Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a coal mine excavation support device with an adjustment function, including a protection block 5, characterized in that: a shell 1 is arranged on both sides of the bottom of the protection block 5, each shell 1 is fixedly connected to the inner wall of the bottom plate 8, a slider 9 is fixedly connected to the top of the bottom plate 8, a motor 10 is fixedly connected to one side of the slider 9, and a support block 13 is fixedly connected to the other side of the slider 9, a bidirectional threaded rod 11 is fixedly connected to the output end of the motor 10, and a plurality of sliders 29 are threadedly connected to the outer wall of the bidirectional threaded rod 11, and each slider 29 is fixedly connected to a connecting rod 13 on both sides.

[0034] Specifically, the motor 10 is started, and the motor 10 is used to provide power support for the rotation of the two-way threaded rod 11, thereby driving the sliders 29 on both sides to move in the opposite direction on the surface of the slider 1 9, and the support block 13 is used to support one end of the two-way threaded rod 11, and the slider 1 9 is used to reduce the friction during the movement of the slider 29. When the sliders 29 on both sides move in the opposite direction, the connecting bar 12 drives one end of the connecting block 2 17 to move synchronously, and the other end of the connecting block 2 17 drives the top plate 19 to move up and down linearly through the connecting bar 4 18. During the rotation of the connecting block 2 17, the connecting block 15 is driven to rotate synchronously through the connecting bar 3 16, and the connecting block 15 is used to enhance the stability of the connecting block 2 17 during its rotation. When the top plate 19 moves up and down, it drives the shell 2 2 to slide on the outer wall of the shell 1, thereby realizing the height adjustment of the support device, avoiding the reduction of the product protection effect due to inappropriate height. This structural design improves the convenience and practicality of the support device during use, and provides users with a better use experience.

[0036] Specifically, when a block on the top of the tunnel falls to the top of the support device, the rolling action of the roller 6 is used to relieve part of the impact force. When the impact force is transmitted to the surface of the rubber block 20 through the shell three 4, the connecting block three 21 is driven to move downward, and the rubber block 20 is used to relieve part of the impact force. While the connecting block three 21 moves downward, it drives the connecting column one 22 and the connecting column two 23 to move downward. The connecting column one 22 moves downward and drives the spring 27 to perform a corresponding extrusion movement through the connecting plate 26. The soft characteristics of the spring 27 are used to relieve the remaining impact force. The connecting column two 23 slides on the inner wall of the fixed column 25 to give the spring 27 a limiting effect, thereby improving the relief effect of the spring 27. This structural design improves the protective effect of the product, protects the life, health and safety of the staff, and at the same time reduces the degree of damage to the protective device caused by the block, thereby extending the service life of the product.

[0037] Working principle: When the support device is in use, the protective device is moved to a specific position, the motor 10 is started, and the output end of the motor 10 is used to drive the bidirectional threaded rod 11 to rotate, thereby driving the sliders 29 on both sides to move in the opposite direction of the slider 1 9, and the connecting strip 1 12 is used to drive the bottom of the connecting block 2 17 to move synchronously, thereby driving the top plate 19 to move up and down through the connecting strip 4 18. During the rotation of the connecting block 2 17, the connecting block 1 15 is driven to rotate through the connecting strip 3 16. During the up and down movement of the top plate 19, the protective block 5 is driven to adjust its height to a specific position through the shell 2 2, thereby realizing the height adjustment of the support device. This design structure avoids the problem of difficulty in protective support due to height mismatched tunnels. The safety and convenience of the support device during use are improved. During the use of the support device, when gravel or other block objects such as gravel on the top of the tunnel hits the top of the support device, the rolling action of the roller 6 reduces the impact force of the block objects on the support device, and the remaining impact force is transmitted to the surface of the rubber block 20 through the outer shell 3 4 to drive the connecting block 3 21 to move downward, and the rubber block 20 is used to reduce the impact force. The connection block 3 21 moves to drive the connecting column 1 22 and the connecting column 2 23 to move downward, and the connecting column 1 22 moves downward to drive the spring 27 to perform a compression movement, and the spring 27 is used to relieve the remaining impact force. The connecting column 2 23 slides on the inner wall of the fixed column 25 to achieve a limiting effect on the spring 27, thereby enhancing the protective effect of the support device, reducing the degree of damage during use, and extending the service life of the product.
