What Is an Action Device?

The operating device is to distribute power and adjust the movement speed of each working mechanism of the rig. A device for changing the movement direction and form of a working mechanism. The operating mechanism of a mechanical transmission drilling rig is generally set with related components, while the operating mechanism of a liquid drive transmission is mostly set together as an independent component.

The controls are

In a human-computer interaction system, a manipulation device refers to various elements, devices, components, mechanisms, and combinations thereof that make a machine start, stop, or change the operating state through human actions (directly or indirectly). Its basic function is to convert the response output of the operator into the input information of the machinery and equipment, and then control the operating status of the machinery and equipment. The most basic principle of the design of the operating device is to enable the operator to continue to operate accurately, comfortably and conveniently within an operation shift without generating early fatigue. To this end, the designer must fully consider the body shape, dimensions and physiological characteristics , Movement characteristics and psychological characteristics, as well as the limits of human physical strength and ability, can make the designed control device achieve high comfort.

There are many types of manipulation devices. According to the different parts of the human body, the arm movements and palm movements are grouped into the same category, which can be divided into two categories: manual manipulation devices and foot manipulation devices. ^[2]

The factors affecting the comfort of the control device mainly include the following four aspects:

(1) The installation position of the control device.

Includes various mechanisms where the device has a direct relationship with the operator: such as

According to the different parts of the human body, in order to facilitate the calculation of the attributes of the human body in the later stage, the manipulations are divided into five basic types:

(1) Hand-grip type: including finger, palm, and arm movements, using the palm as a support reference point, focusing on the grasping behavior of fingers, and arm movements as auxiliary behaviors.

(2) Grip type: including finger, palm, and arm movements, using the wrist as a support reference point, focusing on the contact behavior of the palms, and arm and finger movements as auxiliary behaviors.

(3) Finger touch: Including finger, palm and part of arm movements, taking the joint of the fingers as the support reference point, focusing on the contact behavior of fingers, and the action of palm and arm as auxiliary behaviors.

(4) Pedal type: Including foot, ankle, and lower limb movements. Determine the reference point according to the actual situation. When the operator operates in the standing position, use the foot and ankle joint as the reference point. When the operator operates in the sitting position, use the The neutral position reference point of the seat on which the human body sits is the reference coordinate system.

(5) Pull-grip style: including finger, palm, and arm movements, taking the shoulder-arm connection as the reference point of support, focusing on the rigid body movement of the arms, and finger and palm movements as auxiliary behaviors. ^[2]
