In Business, What is a Lateral Move?

Horizontal transfer equipment refers to the equipment used to transfer the casting slabs to the cooling bed or other sites by using transfer trolleys, traversing machines and push and pull steel machines. There are many types of horizontal transfer equipment, mainly including transfer trolleys, horizontal transfer machines and push and pull steel machines. Large slab casters often use transfer trolleys to complete the lateral transfer of the slab. The transfer trolley is composed of a roller table, a car body, a running device, a slide wire electrical connection device, a buffer device, and electronic control equipment. The roller table set on the trolley is part of the roller bed of the continuous casting machine during the pouring process. After the casting slab is in place, the truck quickly moves laterally and is connected with the roller table of the next process to convey the cast slab One process.

Equipment for lateral transfer of slabs to cooling beds or other sites. The traversing machine generally adopts the upper track type, which is provided with a running device, a lifting arm or a claw and its transmission device. Pushing and pulling steel is a simple horizontal transport equipment, there are many types, such as hydraulic steel pushing machine, electric-mechanical steel pulling machine and so on. The hydraulic pusher consists of a pusher trolley, a swing lever, a synchronous shaft and a hydraulic cylinder. There are many types of electric-mechanical steel drawing machines, such as wire rope-dip claw trolley, steel drawing type and plate chain type. ^[1]

According to the requirements of locomotive and vehicle maintenance process, after the bogie and the body car are disassembled, a tooling equipment is needed to move the bogie to other lanes, further decompose the bogie frame and the motor wheel pair, and disassemble the disassembled frame , Wheelset, motor maintenance work. At the same time, the inspection and assembly of the bogie also requires such tooling equipment to move the bogie to the strand where the car body is located to assemble and connect with the car body. The traditional method is to use the overhead crane and spreader in the warehouse to move the bogie between the various lanes. This method is cumbersome, time-consuming and labor-intensive, and has many potential safety hazards. To this end, the locomotive bogie lateral movement equipment was developed.

1. Technical performance characteristics

Horizontal mobile device control mode is wireless remote control and button control box. By operating the corresponding buttons, the hydraulic jacking automatic compensation mechanism can be raised and lowered, the bogie can be raised to a certain height, and the bogie can be laterally migrated. Relevant technical performance characteristics are as follows: control distance is within 100m; hydraulic system is used for flexible control during operation; lateral mobile equipment walking speed can be adjusted; the driving power supply is battery-powered, and the battery capacity needs to be regularly checked and charged in a timely manner; lateral mobile equipment is continuous The working time is 2h; when horizontal mobile equipment is working, sound and light warning is adopted to prevent accidents.

3. Equipment composition

The main equipment consists of: 1 set of control system; 1 set of hydraulic pump station; 2 sets of driving device; 2 sets of driven device; 2 sets of hydraulic jacking automatic compensation mechanism; 1 set of gantry body frame; 4 sets of auxiliary support.

(1) Control system

The power source of the horizontal mobile equipment uses two sets of batteries, each of which is a group of 16 and a total of 16 batteries (12V 100AH). The reserve electric energy can meet the continuous operation of the load for 2 ~ 4h. Configure the control cabinet and install all control components, integrated boards, controllers, contactors, air switches and other components. The electrical control part has two operation modes of remote control and manual control, which can switch without disturbance. The core of the control part adopts the controller assembly and brushless DC motor of Prion Technology Co., Ltd., with high integration, easy use, low failure rate and strong anti-interference. The remote control can control the lifting and walking of the traverse equipment within a distance of 100m.

(2) Hydraulic pumping station

The hydraulic pump station consists of a hydraulic pump, an integrated valve block, a hydraulic valve, a pipeline, a fuel tank, a DC motor, and a bracket. It has two major functions: supplying oil to the hydraulic cylinder of the lifting mechanism to realize the lifting movement of the bogie; supplying oil to the hydraulic motor of the driving device to realize the forward and backward movement of the bogie.

(3) Driving device

The driving device is composed of a hydraulic motor, a driving wheel assembly, and a support. When the hydraulic pumping station supplies oil to the hydraulic motor, the hydraulic motor rotates, thereby driving the driving wheel to rotate to realize the movement of the traverse equipment.

(4) Driven device

The driven device is composed of a driven wheel assembly, a support and the like. The rotation of the driving wheel drives the rotation of the driven wheel to realize the movement of the traverse device.

(5) Hydraulic jacking automatic compensation mechanism

The hydraulic jacking automatic compensation mechanism consists of a hydraulic cylinder, a single lug base for automatic compensation of the lifting arm, a pin, and a floating support. When the hydraulic pumping station supplies oil to the hydraulic jacking mechanism, the hydraulic jacking mechanism makes the bogie lift.

(6) Gantry body structure

The gantry body frame is used to install and fix components such as a hydraulic lifting mechanism, a driving device, and an auxiliary support, thereby becoming an integral rigid mechanism.

(7) Auxiliary support

The auxiliary support is composed of a support, a shaft, a bearing and a retaining ring. When the traverse device walks to the cross track, the auxiliary support works. During normal walking, the auxiliary support is not in contact with the track.

4.Conclusion

The locomotive bogie lateral movement equipment is a new product developed and developed. After in-depth and detailed research and multiple simulation tests, key components such as control systems, drive devices, and hydraulic jacking automatic compensation mechanisms were optimized and designed to fully meet the requirements of the bogie maintenance process. The development of the locomotive bogie lateral movement equipment not only realizes the transfer of the locomotive bogie between the various lanes in the maintenance warehouse, but also fills the gap in the horizontal movement of the long-distance bogie between the maintenance warehouses in the locomotive section and outside the warehouse. . The operation process of the horizontal mobile device can be semi-automatic wireless remote control, and can also be manually controlled by button operation. The device uses the hydraulic control system and the electronic control system to realize the lifting and moving of the bogie, which is easy to operate (only one person needs to operate), stable movement, adjustable walking speed, accurate positioning, saving manpower, and reducing the labor intensity of employees. The operating safety factor is increased, the working efficiency is improved, and the requirements of the bogie maintenance process are fully met. A number of projects have been implemented for locomotive bogie lateral movement equipment. New projects have been built in the railway bureau's locomotive depot, and high-power maintenance bases have been put into use. Practice has shown that the equipment has stable quality performance, good operating conditions, and satisfactory customers. ^[2]
