DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0045] As described in the background technology, the self-moving machine tail of the related technology includes a conveying device, which is used to transport materials such as gravel and soil generated during the excavation process to the rear. Rollers are set at the bottom of the conveying device, and a driving device is set on the conveying device. The driving device is used to drive the rollers to rotate forward or reverse, so that the rollers drive the conveying device forward or backward in the tunnel.

[0046] However, when there is a turning position in the tunnel, the driving device cannot drive the roller to drive the conveying device to turn, so that the self-moving tail cannot be applied to the tunnel with the turning position.

[0047] In response to the above technical problems, the embodiment of the present application provides a self-moving tail of a tunneling device and a tunneling device. When it is necessary to drive the conveying device forward, the driving end of the first tightening oil cylinder is driven to disengage from the abutment with the top wall of the tunnel, and the first material trailer is detached from the tunnel. The driving end of the second tightening oil cylinder is driven to abut against the top wall of the tunnel to fix the extension mechanism to the tunnel. The first material trailer is driven away from the extension mechanism by the telescopic member, so that the first material trailer drives the control system trailer and the tail body forward a certain distance. At the same time, the deviation adjustment cylinder can be used to drive the abutment The connecting plate abuts against the side wall of the tunnel, thereby adjusting the forward direction of the tail body. Then, the driving end of the first tightening cylinder is driven to abut against the top wall of the tunnel to fix the first material trailer to the tunnel. The driving end of the second tightening cylinder is driven to abut against the top wall of the tunnel to detach the extension mechanism from the tunnel. The extension mechanism is driven by the telescopic cylinder to approach the first material trailer, so that the extension mechanism drives the second material trailer forward a certain distance. By repeating the above steps, the first material trailer and the extension mechanism can move forward and change the forward direction while moving forward.

[0048] When it is necessary to drive the conveying device backward, the first material trailer is fixed to the tunnel by driving the driving end of the first tightening cylinder to abut against the top of the tunnel, and the extension mechanism is detached from the tunnel by driving the driving end of the second tightening cylinder to disengage from the abutment with the top wall of the tunnel, and the extension mechanism is driven away from the first material trailer by the telescopic cylinder, so that the extension mechanism drives the second material trailer to retreat a certain distance, and then, the first material trailer is detached from the tunnel by driving the driving end of the first tightening cylinder to disengage from the abutment with the top wall of the tunnel, and the first material trailer is fixed to the tunnel by the driving end of the second tightening cylinder to abut against the top wall of the tunnel, and the extension mechanism is driven close to the extension mechanism by the telescopic cylinder. , so that the first material trailer drives the control system trolley and the tail body to retreat a distance. By repeating the above steps, the first material trailer and the extension mechanism retreat, so that the conveying device is suitable for tunnels with turning positions, and when there are obstacles in the tunnel, by adjusting the forward or backward direction of the conveying device, it is convenient to drive the conveying device to bypass the obstacles, thereby improving the movement effect of the conveying device in the tunnel; by setting the deviation adjustment cylinder, the relative position between the conveying device and the tunneling equipment can be adjusted, thereby preventing the conveying device from having a position deviation with the tunneling equipment when receiving the materials of the tunneling equipment, indirectly improving the accuracy of the conveying device in receiving the materials of the tunneling equipment.

[0049] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems.

[0053] At least one deviation adjustment device 300 is provided on the conveying device 100 . The deviation adjustment device 300 moves relative to the conveying device 100 to abut or disengage with the side wall of the tunnel, thereby adjusting the forward and backward directions of the conveying device 100 .

[0054] By adopting the above technical solution, the driving device 200 is used to drive the conveying device 100 to move forward and backward simultaneously with the tunneling equipment, thereby facilitating the transportation of the generated materials while the tunneling equipment is excavating, thereby eliminating the need for the tunneling equipment to stop and wait for the transportation of the materials, thereby improving the tunneling efficiency; by adopting the deviation adjustment device 300, when the conveying device 100 moves forward or backward in the tunnel, the deviation adjustment device 300 can abut or disengage from the abutment with the side wall of the tunnel, thereby causing the deviation adjustment device 300 to push the conveying device 100 to move, thereby adjusting the forward and backward directions of the conveying device 100. The direction of the conveying device 100 can be adjusted, so that the conveying device 100 is suitable for tunnels with turning positions, and when there are obstacles in the tunnel, the forward or backward direction of the conveying device 100 can be adjusted to facilitate the conveying device 100 to bypass the obstacles, thereby improving the movement effect of the conveying device 100 in the tunnel; through the setting of the deviation adjustment device 300, the relative position between the conveying device 100 and the tunneling equipment can be adjusted, thereby preventing the conveying device 100 from having a position deviation with the tunneling equipment when receiving materials from the tunneling equipment, indirectly improving the accuracy of the conveying device 100 in receiving materials from the tunneling equipment.

The driving members 310 on both sides respectively drive the abutment members 320 on both sides to abut against the side wall of the tunnel, so that the forward and backward directions of the conveying device 100 can be adjusted to the left or right, thereby improving the adjustment range of the forward and backward directions of the conveying device 100.

[0057] Combine Figures 1 to 4 The driving member 310 includes a deviation adjusting cylinder 311 , and the abutting member 320 includes an abutting plate 321 . The abutting plate 321 is provided on the driving end of the deviation adjusting cylinder 311 .

[0061] Combine Figures 1 to 4 At least two driving members 310 are provided on both sides of the conveying device 100 , and at least one driving member 310 is provided on both ends of the conveying device 100 .

[0062] In this embodiment, four driving members 310 are provided, two of which are provided on one side of the conveying device 100, and the other driving member 310 is provided on the other side of the conveying device 100; in other embodiments, the number of driving members 310 can be adaptively adjusted as needed, for example, the number of driving members 310 is adjusted to six, three of which are evenly distributed along the length direction of the same side of the conveying device 100, and the other three driving members 310 are evenly distributed along the length direction of the other side of the conveying device 100, which can also realize the adjustment of the forward and backward directions of the conveying device 100.

[0063] By adopting the above-mentioned technical solution, by arranging two driving parts 310 on both sides of the conveying device 100, the two deviation adjustment cylinders 311 on the same side of the conveying device 100 can simultaneously adjust the forward direction and backward direction of the conveying device 100, which is further suitable for heavier conveying devices 100, and the forward direction and backward direction of the conveying device 100 can be adjusted at different positions through the deviation adjustment cylinders 311 at both ends of the conveying device 100, thereby further improving the steering accuracy of the conveying device 100.

By providing three of the first fixing member 210 and the second fixing member 220, the fixing strength of the first material trailer 110 and the extension mechanism 120 to the tunnel can be further improved. By providing three of the telescopic member 230, the speed at which the first material trailer 110 and the extension mechanism 120 approach and move away from each other can be further improved.

[0073] By adopting the above technical solution, when it is necessary to drive the conveying device 100 forward, the first material trolley 110 is detached from the tunnel by the first fixing member 210, the extension mechanism 120 is fixed to the tunnel by the second fixing member 220, and the first material trolley 110 is driven away from the extension mechanism 120 by the telescopic member 230, so that the first material trolley 110 advances a certain distance, and then, the first material trolley 110 is fixed to the tunnel by the first fixing member 210, the extension mechanism 120 is detached from the tunnel by the second fixing member 220, and the extension mechanism 120 is driven close to the first material trolley 110 by the telescopic member 230, so that the extension mechanism 120 advances a certain distance, and by repeating the above steps, the first material trolley 110 and the extension mechanism 120 can advance; when it is necessary to drive the conveying device 100 backward, the first material trolley 110 is detached from the tunnel by the first fixing member 210 The extension mechanism 120 is fixed to the tunnel by the second fixing member 220, and the extension mechanism 120 is driven away from the first material trolley 110 by the telescopic member 230, so that the extension mechanism 120 retreats a certain distance.

By adopting the setting of the telescopic cylinder 231, very large thrust and pulling force can be generated, which is suitable for the heavier conveying device 100; the deviation adjustment cylinder 311 is compact in design and occupies a small space, which is convenient for use with the conveying device 100 in a narrow tunnel; through precise hydraulic control, the deviation adjustment cylinder 311 can achieve very precise position control and speed control, thereby improving the steering accuracy of the conveying device 100; and the deviation adjustment cylinder 311 can quickly respond to control signals to achieve rapid start and stop; the stroke, speed and force of the deviation adjustment cylinder 311 can be adjusted by the hydraulic system to adapt to different work requirements; the deviation adjustment cylinder 311 can work under a variety of environmental conditions, including extreme temperatures and harsh industrial environments.

[0085] An embodiment of the present application also provides a tunneling device, including a tunneling machine and a self-moving tail of the tunneling device of any of the above embodiments arranged on the tunneling machine.

[0086] Among them, the specific structure of the self-moving tail of the tunneling equipment has been described in detail in the above embodiments and will not be repeated here.

[0087] The tunneling equipment provided in the embodiment of the present application is provided with a self-moving tail of the tunneling equipment. When it is necessary to drive the conveying device 100 forward, the driving end of the first tightening oil cylinder 211 is driven to disengage from the abutment with the top wall of the tunnel, so as to detach the first material trolley 110 from the tunnel, and the driving end of the second tightening oil cylinder 221 is driven to abut against the top wall of the tunnel to fix the extension mechanism 120 to the tunnel. The first material trolley 110 is driven away from the extension mechanism 120 by the telescopic member 230, so that the first material trolley 110 drives the control system trolley 140 and the tail body 130 to advance a certain distance. At the same time, the abutment plate 321 can be driven by the deviation adjustment oil cylinder 311 It abuts against the side wall of the tunnel, thereby adjusting the forward direction of the tail body 130, and then, by driving the driving end of the first tightening cylinder 211 to abut against the top wall of the tunnel, the first material trailer 110 is fixed to the tunnel, and by driving the driving end of the second tightening cylinder 221 to abut against the top wall of the tunnel, the extension mechanism 120 is detached from the tunnel, and the extension mechanism 120 is driven by the telescopic cylinder 231 to approach the first material trailer 110, so that the extension mechanism 120 drives the second material trailer 150 to move forward a certain distance. By repeating the above steps, the first material trailer 110 and the extension mechanism 120 can move forward and change the forward direction while moving forward.

[0088] When it is necessary to drive the conveying device 100 backward, the driving end of the first tightening cylinder 211 is driven to abut against the top of the tunnel to fix the first material trolley 110 to the tunnel, and the driving end of the second tightening cylinder 221 is driven to disengage from the abutment with the top wall of the tunnel to detach the extension mechanism 120 from the tunnel, and the extension mechanism 120 is driven away from the first material trolley 110 by the telescopic cylinder 231, so that the extension mechanism 120 drives the second material trolley 150 backward for a distance, and then, the driving end of the first tightening cylinder 211 is driven to disengage from the abutment with the top wall of the tunnel to detach the first material trolley 110 from the tunnel, and the driving end of the second tightening cylinder 221 is driven to abut against the top wall of the tunnel to fix the extension mechanism 120 to the tunnel, and the first material trolley 110 is driven close to the tunnel by the telescopic cylinder 231. The extension mechanism 120 enables the first material trolley 110 to drive the control system trolley and the tail body 130 to retreat a certain distance. By repeating the above steps, the first material trolley 110 and the extension mechanism 120 retreat, so that the conveying device 100 is suitable for tunnels with turning positions, and when there are obstacles in the tunnel, by adjusting the forward or backward direction of the conveying device 100, it is convenient to drive the conveying device 100 to bypass the obstacles, thereby improving the movement effect of the conveying device 100 in the tunnel; by setting the deviation adjustment cylinder 311, the relative position between the conveying device 100 and the tunneling equipment can be adjusted, thereby preventing the conveying device 100 from having a position deviation with the tunneling equipment when receiving the materials of the tunneling equipment, indirectly improving the accuracy of the conveying device 100 in receiving the materials of the tunneling equipment.
