Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coal mine tunneling auxiliary equipment, specifically a segmented support device. Background Technology
[0002] A mine is an area where humans extract coal resources in coal-rich mining areas. During coal mining, tunneling machines are typically used. To prevent loosened and falling rocks from the roof after blasting and causing injury, temporary support devices are needed at the bottom of the roof in the tunneling roadway. Tunneling is the work of excavating shafts, tunnels, and chambers of various shapes, cross-sections, or crisscrossing structures within rock (soil) or mineral layers. The tunneling process is divided into main processes and auxiliary processes. The main processes refer to those completed directly on the working face to ensure its progress, as well as the support work carried out in the tunneling area. The main processes are determined by the nature of the rock through which the tunnel passes. When tunneling hard rock, the main processes include drilling, loading explosives, blasting, ventilation, safety inspection of the working face, rock loading, and tunnel support work.
[0003] A support device is disclosed in existing publication CN222121548U. The support device includes a telescopic component and a support component. The telescopic component includes a support top plate and an extended support plate, which is arranged parallel to the support top plate and movably positioned relative to it. The telescopic component is mounted on the support component. By movably positioning the extended support plate, it has an initial position coinciding with the support top plate and a support position extending beyond it. By providing the support component to support the telescopic component, and by extending the extended support plate beyond the support top plate to expand the support area on the side of the support top plate, the overall support area of the telescopic component is increased. This solves the problem of difficulty in adjusting the top support range of existing support devices.
[0004] In current coal mine roadway support operations, the depth of tunneling directly determines the length of the roadway when using a tunneling machine. As the roadway length increases, the distance requiring support also increases. Due to the long roadway length, to ensure the stability of the entire roadway, support devices must be installed at multiple locations to support the entire roadway structure and prevent the collapse of a section of the roadway due to insufficient support points. Therefore, multiple support device points are set up in the roadway at different distances. As the roadway length continues to increase, the number of support devices required will also gradually increase. However, when performing segmented support, these support devices often lack effective splicing structures, resulting in inconsistent distances between different support sections. There is insufficient tension between adjacent support devices, and the interconnectivity between them is poor. This directly affects the balance between adjacent support devices. Therefore, in actual segmented support operations, due to these factors, the support effect is often unsatisfactory.
[0005] Therefore, those skilled in the art have provided a segmented support device to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this utility model is to provide a segmented support device to solve the problem mentioned in the background art that the existing support devices lack connectivity between adjacent devices when performing segmented support, resulting in poor balance between adjacent support devices and unsatisfactory support effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A segmented support device includes: a support frame, a support plate rotatably mounted on the top of the support frame, a lifting cylinder mounted on the bottom of the support plate, an mounting frame fixedly mounted on the outside of the lifting cylinder, and a telescopic cylinder fixedly connected to the front end of the mounting frame, a connecting seat fixedly mounted on the output end of the telescopic cylinder, and a connecting frame fastened to the upper surface of the connecting seat by screws, a stabilizing rod fixedly mounted on the surface of the connecting frame, a hook fixedly connected to the front end of the stabilizing rod, and a connecting hook connected to the inside of the front end of the hook.
[0009] As a further embodiment of this utility model: the telescopic cylinder is fixedly connected to the lifting cylinder through the mounting bracket, and the telescopic cylinder is connected to the connecting bracket through the connecting seat.
[0010] As a further improvement of this utility model: the connecting frame and the stabilizing rod are fixedly connected, and both the connecting frame and the stabilizing rod are vertically symmetrical about the symmetrical center line of the connecting seat.
[0011] As a further improvement of this utility model: the hook and the front end of the connecting frame are fixedly connected, and the hook and the connecting hook are hook-and-hang connection.
[0012] As a further improvement of this utility model, the external structure of the connecting hook is shaped like an "S".
[0013] As a further embodiment of this utility model: a rocker arm is rotatably connected to the surface of the connecting seat, and a rotating shaft is provided between one end of the rocker arm and the connecting seat. The rocker arm is rotatably connected to the connecting seat through the rotating shaft, and a hydraulic cylinder is rotatably mounted on the upper surface of the rocker arm.
[0014] As a further embodiment of this utility model: a pad is fixedly installed at the front end of the swing arm, and a base is fixedly installed at the lower end of the pad; an extension arm is fixedly connected to the outer edge of the base, and an anti-slip foot is fixedly installed at the front end of the extension arm.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The support frame and the support plate are designed with a rotating structure. This structure allows the support plate to be adjusted in angle as needed to adapt to roadway walls of different shapes and sizes. A lifting cylinder is used to adjust the support plate. The introduction of the lifting cylinder allows the support plate to move up and down according to actual support requirements, thereby effectively supporting and fixing the mine wall. In addition, a telescopic cylinder is installed on one side of the lifting cylinder, further enhancing the flexibility and adaptability of the device. The output end of the telescopic cylinder is connected to a connecting seat, which is connected to a hook via a connecting frame and a stabilizing rod. The design of these components not only ensures a fixed connection between the stabilizer bar and the connecting seat, but also greatly enhances the connection stability and strength of the connecting frame itself through the addition of the stabilizer bar. By adjusting the position of the connecting seat using a telescopic cylinder, the distance between adjacent support devices can be adaptively adjusted. This adjustment allows adjacent support devices to move closer or further apart as needed, thereby achieving the best support effect. When it is necessary to connect adjacent support devices, a connecting hook can be used to complete this process. The design of the connecting hook makes the connection between adjacent support devices simple and secure.
[0017] 2. When carrying out segmented support, the connection between the connecting seats not only helps to maintain the equidistant setting of each support device, but also greatly improves the stability between the support devices and the overall balance through this uniform distribution. This design not only improves work efficiency, but also ensures the safety of mine tunnel construction. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4This utility model provides a segmented support device, including: a support frame 1, a support plate 2 rotatably mounted on the top of the support frame 1, a lifting cylinder 3 mounted on the bottom of the support plate 2, an mounting frame 4 fixedly mounted on the outside of the lifting cylinder 3, and a telescopic cylinder 5 fixedly connected to the front end of the mounting frame 4. A connecting seat 6 is fixedly mounted on the output end of the telescopic cylinder 5, and a connecting frame 7 is fastened to the upper surface of the connecting seat 6 by screws. A stabilizing rod 8 is fixedly mounted on the surface of the connecting frame 7. The telescopic cylinder 5 is fixedly connected to the lifting cylinder 3 through the mounting frame 4, and the telescopic cylinder 5 is connected to the connecting frame 7 through the connecting seat 6. The connecting frame 7 and the stabilizing rod 8 are fixedly connected, and the connecting frame 7 and the stabilizing rod 8 are symmetrical about the center line of the connecting seat 6. By using the telescopic cylinder 5 to adjust the position of the connecting seat 6, the connecting seat 6 can be adjusted according to the distance between adjacent support devices. The design of the connecting seat 6 not only includes a connecting frame 7, but also a stabilizing tie rod 8. The two are parallel to each other, and the two ends of the stabilizing tie rod 8 are firmly fixed to the connecting frame 7 with screws. The purpose of this structural design is to use the stabilizing tie rod 8 to significantly enhance the connection strength of the connecting frame 7, thereby improving the overall hardness and stability of the connecting frame 7, and ensuring the stability and reliability of the entire support device.
[0025] A rocker arm 11 is rotatably connected to the surface of the connecting seat 6, and a rotating shaft 14 is provided between one end of the rocker arm 11 and the connecting seat 6. The rocker arm 11 is rotatably connected to the connecting seat 6 through the rotating shaft 14. A hydraulic cylinder 12 is rotatably mounted on the upper surface of the rocker arm 11. A pad 13 is fixedly mounted on the front end of the rocker arm 11, and a base 15 is fixedly mounted on the lower end of the pad 13. An extension arm 16 is fixedly connected to the outer edge of the base 15, and an anti-slip foot 17 is fixedly mounted on the front end of the extension arm 16. The connecting seat 6 not only has a fixed installation of the connecting frame 7 and the stabilizing rod 8, but also a rotatable swing arm 11. The presence of these connecting frames 7 and stabilizing rods 8 significantly improves the overall stability of the hook 9. The swing arm 11, through its rotating structure, can flexibly adjust the support position of the foot 15, thereby greatly enhancing the stability of the docking connection between adjacent support devices. This design effectively avoids the docking point being in a suspended state, thereby reducing the risks that may be caused by unstable docking. In addition, three sets of extended arms 16 are fixedly installed in a ring on the foot 15, so that the anti-slip foot 17 provides three-point anti-slip support. The setting of these three sets of extended arms 16 further improves the stability of the foot 15, ensuring the stability and reliability of the entire device in various working environments.
[0026] The front end of the stabilizing tie rod 8 is fixedly connected to a hook 9, and the front end of the hook 9 is internally connected to a connecting hook 10. The hook 9 is fixedly connected to the front end of the connecting frame 7, and the hook 9 and the connecting hook 10 are hooked together. The external structure of the connecting hook 10 is S-shaped. By using the S-shaped connecting hook 10, the hooks 9 on adjacent support devices are hooked together, thus smoothly completing the docking work between adjacent support devices. This docking method ensures that the spacing between adjacent support devices can be maintained in a stable state, thereby achieving the purpose of segmented support. The setting of the connecting hook 10 not only facilitates movable hooking, but also allows the support devices to be easily separated and reconnected when needed, greatly improving the flexibility and efficiency of the operation.
[0027] The working principle of this utility model is as follows:
[0028] When using this utility model, firstly, the support device is placed in the area requiring support. The height of the support plate 2 is adjusted using the lifting cylinder 3 to adapt to different working environments and needs, supporting the mine wall. Subsequently, the position of the connecting seat 6 is precisely adjusted using the telescopic cylinder 5 to ensure that the spacing between adjacent support devices reaches the preset value. In the design of the connecting seat 6, the connecting frame 7 is fixedly connected to the stabilizing rod 8, so that the support device can remain stable under force and is not prone to deformation or damage. At the same time, the hook 9 is hooked to the connecting hook 10, connecting the hooks 9 on adjacent support devices together, so that adjacent support devices can be tightly connected to form an integral support structure, and in the segmented... During support, adjacent support devices are interconnected. If the position or spacing of the support devices needs to be adjusted during use, the position of the connecting seat 6 can be adjusted by using the telescopic cylinder 5 to adjust the spacing between adjacent support devices. The operation is simple and quick. In addition, the setting of the swing rod 11 allows the base 15 to flexibly adjust the support position. Through the rotation structure between the swing rod 11 and the rotating shaft 14, the hydraulic cylinder 12 is used to pull the swing rod 11 to rotate, thereby adjusting the angle of the swing rod 11. The base 15 at the lower end of the pad foot 13 contacts the ground and provides support, further enhancing the stability of the support device. The design of the anti-slip foot 17 effectively prevents the support device from sliding or displacing during operation, ensuring the support effect.
