For example, the mobile device is a self-moving tail of a belt conveyor. A belt conveyor (also called a belt conveyor) is a commonly used continuous transport device. Each time the belt conveyor is extended, a section of belt conveyor and a frame are required to be added. During the extension process or the adding process, the tail needs to be detached from the rubber belt conveyor, the middle frame is added, then the tail is carried in place, and the rubber belt is connected again. The whole extension work, especially the work of the carrier tail therein, has high labor intensity and large workload, needs a long time and greatly influences the progress of operations such as engineering construction and the like.

The rubber belt conveyor is a telescopic belt conveyor, the length of a belt can be automatically adjusted, the position of the tail of the rubber belt conveyor is only required to be adjusted, and a section of belt supporting frame is additionally arranged in the middle of the rubber belt conveyor. In another embodiment, the belt conveyor is not a telescopic belt conveyor, so that after the position of the tail is adjusted, a section of belt conveyor is required to be added in addition to a section of belt supporting frame.

In the embodiment of the present invention shown in fig. 1 and fig. 2, the belt conveyor self-moving tail includes: a frame 1; an auxiliary support device 2; and a walking support device 3, wherein the auxiliary support device 2 and the walking support device 3 are spaced apart from each other in the longitudinal direction of the frame 1.

The lifting and lowering of the auxiliary support 2 is achieved by the extension and retraction of the lift cylinders.

The auxiliary supporting devices 2 are usually arranged in groups, each group comprising one auxiliary supporting device 2 on the left and one on the right. This may improve the stability of the support. At least two sets of auxiliary support means 2 are arranged spaced apart from each other, typically in the longitudinal direction of the frame. More sets of auxiliary support devices 2 (e.g., 8 sets of auxiliary support devices 2 in one embodiment) may also be provided on the frame 1 as needed to further improve the stability of the support, and an ultra-long frame may be provided.

The elevation cylinder is a hydraulic cylinder, for example, supplied with pressure by a hydraulic source provided on the frame, and controlled by a control unit provided on the frame.

Advantageously, the raising cylinders of the same set of auxiliary support means 2 are controlled by the same valve or set of valves, acting in synchronism. It should be noted that the synchronized action does not mean that the extended lengths are necessarily the same, but rather that the same support force is provided. For example, after the lower end of one side contacts the ground and the lower end of the other side does not contact the ground, the lower end of the other side continues to extend downward until contacting the ground, and then the pressures of the lift cylinders of both sides are raised synchronously.

The telescopic auxiliary supporting device with the oil cylinder is adopted, so that the auxiliary supporting device can be lifted up and fall down. Therefore, compared with the fixed supporting device, the device can better avoid the protrusions on the ground. And when the support is provided for the frame, the support can adapt to the fluctuation condition of the ground, better support the frame and play a role in leveling the frame.

That is, the walking support 3 can be adjusted in three directions.

The walking support devices 3 are typically arranged in groups, each group comprising one walking support device 3 on the left and one on the right. This may improve the stability of the support. It is usually necessary to provide at least two sets of walking supports 3 spaced apart in the longitudinal direction of the frame (e.g., one set at each end in the longitudinal direction). If necessary, more sets of walking supporters 3 (for example, 8 sets of walking supporters 3 in one embodiment) may be provided on the frame 1, so as to further improve the stability of the support, and an ultra-long frame may be provided. For example, the walking support devices are bilaterally symmetrical and are in a group of two, and the walking support devices are respectively arranged in front and at back, and comprise at least four support cylinders, four horizontal pushing cylinders, two lateral deviation adjusting cylinders and four groups of roller mechanisms, and the walking support devices are in the same structure.

After the transverse pushing, namely the left and right adjustment, is in place, the auxiliary supporting device 2 falls down, the walking supporting device 3 is lifted up, and the auxiliary supporting device 2 supports the machine frame 1. Then the deviation-adjusting oil cylinder 63 retracts, the walking supporting device is pulled to move transversely relative to the frame 1, and after the work is finished, the walking supporting device 3 falls down to finish one-time transverse adjustment. If necessary, the lateral adjustment is continued and the next cycle is repeated. The adjustable auxiliary supporting device and the auxiliary supporting device are mutually lifted and fall in the transverse adjusting process, and all fall after one-time transverse adjustment of the walking is completed to jointly support the rack. The deviation adjusting oil cylinder 63 is used for realizing the left-right movement of the front part, the left-right movement of the rear part or the whole left-right movement of the frame so as to adjust the operation center deviation of the belt conveyor.

The vertical drive unit is, for example, a hydraulic cylinder; the hydraulic drilling machine moves up and down, for example, guided by a slide rail. When the self-moving tail needs to be anchored relative to the ground, for example, after the self-moving tail completes the whole travel, the hydraulic drilling machine of the anchoring device drills a drill rod into the ground under the action of hydraulic force. The drill rod is used as an anchor rod to anchor the self-moving tail.

In an alternative embodiment, the anchoring means 4 are mounted on the auxiliary support means 2. For example on the cylinder of the lift cylinder of the auxiliary support 2.
