[0002] The invention patent application of our company with the application number CN202410231226.6 - a novel mobile end isolation support, includes a crawler chassis and a hydraulic support. The hydraulic support is arranged on the upper end face of the crawler chassis; one side of the hydraulic support is provided with a side retaining wall through a connecting piece in a hinged structure. Both ends of the driving oil cylinder are respectively hinged to the base of the hydraulic support and the connecting piece to drive the side retaining wall to rotate around the hinge point; a support oil cylinder is vertically arranged on the hydraulic support in a fixed structure. The support oil cylinder extends downward into the crawler chassis and is provided with a tray. The tray is arranged at the lower end of the support oil cylinder in a hinged structure; it transfers the gravity of the hydraulic support and the upward pressure it receives to the ground, reducing the load on the crawler chassis and also improving the service life of the crawler chassis.

[0003] This patent application sets the side retaining wall on the crawler chassis through a connecting piece, restricting the position of the side retaining wall in terms of height. For roadways with a height exceeding 5 meters, that is, ultra-high standard roadways, due to the limited telescopic range at the lower part of the side retaining wall, the upper part cannot completely block the roadway, severely restricting the application range of this isolation support. Summary of the Utility Model:

[0004] To solve the above technical problems, the utility model provides a crawler-mounted rapid roadway blocking device, and the technical solution adopted is:

[0005] A crawler-mounted rapid roadway blocking device, comprising:

[0006] A crawler chassis, on the upper end face of which a base is arranged;

[0007] A top beam and a connecting rod mechanism, one end of the top beam is connected to the base through the connecting rod mechanism;

[0008] A telescopic column, both ends of which are respectively connected to the base and the top beam;

[0009] Two juxtaposed movable arms, one end of each movable arm is connected to the top beam in a hinged structure;

[0010] A power oil cylinder, one end of which is hinged to the movable arm and the other end is hinged to the top beam;

[0011] A side retaining wall, the inner side of which is connected to the movable arm in a hinged structure.

[0012] Furthermore, an installation seat is arranged on the lower end face of the top beam in a fixed structure;

[0013] The top beam is respectively hinged to the movable arm and the power oil cylinder through the mounting seat.

[0014] Furthermore, the mounting seat is provided with a support arm in a hinged structure, the other end of the support arm is connected to the side retaining wall in a hinged structure, and the support arm is arranged parallel to the movable arm.

[0017] The adjusting rod is provided with insertion holes adapted to the pin holes, and the insertion holes and the pin holes are respectively penetrated by pin shafts.

[0018] The beneficial effects of the utility model are as follows: The side retaining wall is installed on the top beam through the movable arm, and the height of the top beam is controlled by the telescopic column, which expands the movement range of the side retaining wall. Furthermore, after the side retaining wall is extended, the requirements for plugging ultra-high roadway can be met, and the applicable range is expanded.

[0019] By arranging the support arm and the movable arm to form a link structure, the movement stability of the side retaining wall is improved.

[0024] To make the purpose, technical solutions and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the drawings and the following embodiments, so that the public can better master the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0025] A crawler - type rapid roadway plugging device, including a crawler chassis 1. On the upper end face of the crawler chassis 1, there is a base 2. The base 2 is connected to a roof beam 4 through a connecting rod mechanism 3. Between the base 2 and the roof beam 4, there are at least two telescopic columns 5. The roof beam 4 is provided with two juxtaposed movable arms 7 in an articulated structure manner. The other end of the movable arm 7 is provided with a side retaining wall 10 through an articulated structure. The movable arm 7 is provided with a power cylinder 8 through an articulated structure. The other end of the power cylinder 8 is hinged to the roof beam 4 to drive the movable arm 7 to rotate around the hinge point with the roof beam, install the side retaining wall 10 on the roof beam 4 through the movable arm 7, and control the height of the roof beam 4 through the telescopic column 5, expanding the vertical movement range of the side retaining wall 10. Thus, after the side retaining wall 10 is extended, it can meet the requirements of plugging ultra - high roadways, expanding the scope of application.

[0026] It should be elaborated that on the lower end face of the roof beam 4, there is a mounting seat 6 arranged in a fixed structure. The roof beam 4 is respectively hinged to the movable arm 7 and the power cylinder 8 through the mounting seat 6, which is convenient for installation and improvement on the basis of the existing hydraulic support, saving the design cost.

[0027] It should be noted that the mounting seat 6 is provided with a support arm 9 in an articulated structure manner. The other end of the support arm 9 is connected to the side retaining wall 10 in an articulated structure manner, and the support arm 9 is arranged parallel to the movable arm 7. By setting the support arm 9, a link structure is formed with the movable arm 7, improving the stability of the movement of the side retaining wall.

[0028] In another embodiment, the support arm 9 includes an adjusting cylinder 91 hinged to the mounting seat 6. The output shaft of the adjusting cylinder 91 is provided with an adjusting rod 92 in a fixed structure manner. The other end of the adjusting rod 92 is connected to the side retaining wall 10 in an articulated structure manner. When the roadway is uneven, the angle of the side retaining wall can also be adjusted through the telescopic movement of the adjusting cylinder, ensuring that the side retaining wall is in a vertical state, and it is also convenient for the assembly of multiple adjacent side retaining walls, improving the assembly efficiency.

[0029] Specifically, two pin holes are arranged at intervals along the axis of the output shaft of the adjusting cylinder 91. The adjusting rod 92 is provided with jacks 11 adapted to the pin holes. The jacks 11 and the pin holes are respectively penetrated by pin shafts, which is convenient for disassembly and replacement in case the adjusting cylinder 91 is damaged.

[0030] The working principle and process of the present utility model are as follows:

[0031] The first step is to start the crawler chassis 1 to a predetermined position;

[0032] The second step is to lift the roof beam 4 to a predetermined height by using the telescopic column 5 according to the roadway height;

[0033] In the third step, start the power cylinder 8. The power cylinder 8 drives the movable arm 7 to rotate around the hinge point with the mounting seat 6. At the same time, the support arm 9 also rotates to send the side retaining wall 10 outward;

[0034] In the fourth step, according to the on-site situation, if the inclination angle of the side retaining wall 10 needs to be adjusted, start the adjusting cylinder 91. The output shaft of the adjusting cylinder 91 extends, causing the length of the support arm 9 to increase. The side retaining wall 10 rotates around the hinge point with the movable arm 7 until the side retaining wall 10 becomes vertical;

[0035] In the fifth step, start the telescoping of the side retaining wall 10 until both the upper and lower ends are in contact with the roadway to complete the operation.
