Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-5 The present invention provides a technical solution: a coal mine tunneling support device, including a protective plate 1 and a combination mechanism 2, wherein the combination mechanism 2 is provided on one side of the surface of the protective plate 1;

[0023] The combined mechanism 2 includes a track 201, a fixing block 202, a side plate 203, a first cylinder 204, a top plate 205, an integrated groove 206, a contact plate 207, an arched plate 208, a first threaded groove 209, a threaded cover 210, a second cylinder 211, a connecting hook 212, a support plate 213, and a second threaded groove 214. The track 201 is embedded inside the protective plate 1. The fixing block 202 is fixedly connected to one side of the protective plate 1, and the side plate 203 is fixedly connected to one end of the protective plate 1. The first cylinder 204 is installed on one side of the fixing block 202, and the other side of the side plate 203 is fixedly connected to the first cylinder 204. A top plate 205 is fixedly connected to the side plate 203. An integrated groove 206 is formed on one side of the side plate 203. A contact plate 207 is connected to the other side of the first cylinder 204. An arched plate 208 is connected to the other side of the top plate 205. A first threaded groove 209 is formed on one side of the top plate 205. A threaded cap 210 is threadedly connected to the inside of the integrated groove 206. A second cylinder 211 is installed on one side of the integrated groove 206. A connecting hook 212 is threadedly connected to the inside of the first threaded groove 209. A support plate 213 is fixedly connected to the other side of the second cylinder 211. A second threaded groove is formed on one side of the support plate 213. 214. Through the arrangement of track 201, fixing block 202, side plate 203, first cylinder 204, top plate 205, integrated groove 206, contact plate 207, arched plate 208, first threaded groove 209, threaded cover 210, second cylinder 211, connecting hook 212, support plate 213, and second threaded groove 214, in use, firstly, the connecting hook 212 is installed into the first threaded groove 209 and the second threaded groove 214, and the two sides of the protective net are respectively fixed to the connecting hook 212 of the first threaded groove 209 and the second threaded groove 214. Then, the track 201... Move the device to the location requiring support, then activate the first cylinder 204 and the second cylinder 211. The first cylinder 204 will drive the contact plate 207 to contact the ground, thereby increasing the overall support capacity of the entire arch structure and protecting some components. At the same time, the second cylinder 211 will drive the support plate 213 to move. When the support plate 213 is in contact with both sides of the mine shaft, the support is completed. Simultaneously, the movement of the support plate 213 will drive the connecting hook 212 on the second threaded groove 214 to move, thereby unfolding the protective net and protecting the second cylinder 211 and other components, improving the stability during support.

[0024] Furthermore, four sets of fixing blocks 202 are provided on the protective plate 1. The fixing blocks 202 are evenly distributed on the protective plate 1. Due to the uniform distribution of the fixing blocks 202, they can provide balanced support force on the protective plate 1, making the structure of the entire device more stable and preventing loosening or displacement during use. The even distribution of the fixing blocks 202 on the protective plate 1 ensures that the entire protective plate 1 and other related components maintain a consistent stress state during operation, increasing the stability and pressure resistance of the system. At the same time, a first cylinder 204 is installed on one side of the fixing block 202. The cylinder affects the movement of the contact plate 207 through its extension and retraction. The fixing block 202 provides a fixed support point for the cylinder, ensuring that the cylinder can work in a stable environment.

[0025] Furthermore, both the protective plate 1 and the side plate 203 are provided in two sets. The protective plate 1, side plate 203, top plate 205 and arch plate 208 form a closed arch structure. Through the arrangement of the side plate 203, top plate 205 and arch plate 208, and through the combination of the arch plate 208, top plate 205 and side plate 203, the overall structure can evenly distribute and bear external forces from all directions, enhancing the compressive strength and durability of the device, and ensuring the stability of long-term operation. In general, the synergistic effect of the side plate 203, top plate 205 and arch plate 208 is the key factor for the stability, durability, ease of maintenance and efficient operation of this mechanism. Together, they provide the necessary support, protection and structural strength for the entire system.

[0026] Furthermore, the contact plate 207 forms a sliding structure with the protective plate 1 through the first cylinder 204. One side of the contact plate 207 is in contact with the ground. The main function of the contact plate 207 is to provide stable support by contacting the ground. The design of the contact plate 207 ensures that the device can be firmly held on the ground during operation, preventing displacement or tilting due to vibration or external force. At the same time, the contact surface of the contact plate 207 usually has a large area, which can distribute the pressure acting on the contact plate 207, increase the stability of the ground contact, and ensure that the equipment will not tilt or become unstable due to uneven local force.

[0027] Furthermore, one side of the second cylinder 211 is fitted with the threaded cover 210. The integrated groove 206 is provided in four sets on the side plate 203 and is symmetrically distributed along the side plate 203. Through the setting of the integrated groove 206, the integrated groove 206 provides installation and support space for multiple key components, such as the threaded cover 210 and the second cylinder 211. These components are firmly fixed in the groove through the integrated groove 206, thereby ensuring that they will not loosen or shift during use. The integrated groove 206 provides a standardized installation position for these components, enabling each component to be accurately positioned and ensuring their stability and safety during equipment operation. At the same time, the threaded design in the integrated groove 206 allows the components (such as the threaded cover 210 and the second cylinder 211) to be easily installed, disassembled, or replaced. By rotating the threaded cover 210 and other components, maintenance or replacement can be easily performed, reducing the complexity and time cost of equipment maintenance.

[0028] Furthermore, six sets of first threaded grooves 209 are provided on one side of the top plate 205, and are evenly distributed. Through the setting of the first threaded grooves 209, the first threaded grooves 209 are located on one side of the top plate 205. Their main function is to provide a threaded connection interface, so that the connecting hook 212 can be threadedly engaged with the first threaded grooves 209, ensuring a stable connection between the connecting hook 212 and the top plate 205. Through the threaded connection, the first threaded grooves 209 can firmly fix the connecting hook 212, and connect other component protective nets through the hooks to maintain the integrity and stability of the structure.

[0029] Furthermore, the dimensions of the first threaded groove 209 and the second threaded groove 214 are matched, and the positions of the first threaded groove 209 and the second threaded groove 214 are aligned. Through the setting of the second threaded groove 214, the position and size of the second threaded groove 214 match the first threaded groove 209, and its interior can also cooperate with the connecting hook 212. This design ensures that the protective net can form a stable connection between the top plate 205 and the support plate 213 through the connecting hook 212, effectively protecting the components and extending the service life of the parts.

[0030] Furthermore, the second threaded groove 214 also has a connecting hook 212 threaded inside. The connecting hooks 212 in the first threaded groove 209 and the second threaded groove 214 are of different models. The main function of the connecting hook 212 is to connect with other components (such as top plate 205, support plate 213, etc.) through the first threaded groove 209 and the second threaded groove 214, so as to ensure that the protective net can be installed simply and quickly. When supporting, it can effectively protect the internal components, thereby extending the service life of the components.

[0031] Working principle: First, the connecting hook 212 is installed into the first threaded groove 209 and the second threaded groove 214, and the two sides of the protective net are fixed to the connecting hook 212 of the first threaded groove 209 and the second threaded groove 214 respectively. Then, the device is moved to the position that needs support by the track 201. Then, the first cylinder 204 and the second cylinder 211 are activated. The first cylinder 204 will drive the contact plate 207 to contact the ground, thereby increasing the overall support capacity of the entire arch structure and protecting some components. At the same time, the second cylinder 211 drives the support plate 213 to move. When the support plate 213 is in contact with the two sides of the mine tunnel, the support is completed. At the same time, the movement of the support plate 213 also drives the connecting hook 212 on the second threaded groove 214 to move, thereby unfolding the protective net, thereby protecting the second cylinder 211 and other components and improving the stability during support.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
