Technical Field

[0001] This utility model relates to the field of support device technology, specifically a temporary support device for roadways. Background Technology

[0002] Mining is the technology and science of extracting mineral resources from within the Earth's crust and on its surface. In a broader sense, mining also includes the extraction of coal and oil. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, while non-metallic ores are important chemical raw materials and building materials.

[0003] A patent search revealed a document titled "A Temporary Support Device for Roadways" (publication number "CN218376518U"). This device allows for adjustment in both lateral and longitudinal directions, enabling it to be adapted to different roadway sizes. However, its overall structure cannot be stowed away, making relocation extremely inconvenient and hindering the ease of transport by workers. Therefore, this invention designs a temporary support device for roadways to address these problems. Utility Model Content

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a temporary support device for a tunnel includes a support plate 1, a sliding plate 2, a rotating plate 3, and a connecting plate 4. There are two support plates 1, which are parallel to each other. The sliding plate 2 is slidably disposed inside the support plate 1. The rotating plate 3 is rotated onto the upper inner side of the sliding plate 2. The connecting plate 4 is slidably sleeved on the outside of the rotating plate 3. The inner side of the rotating plate 3 is made of rubber. The two connecting plates 4 are designed to be rotatably connected. A drive assembly 5 is provided on the outer wall of the support plate 1. The drive assembly 5 includes a motor 501 fixed to the lower outer side of the support plate 1. A worm gear 502 is fixedly disposed at the output end of the motor 501. The worm gear 502 rotates through the support plate 1. A rotating rod 503 is rotated inside the support plate 1. The rotating rod 503 is threaded through the sliding plate 2. A worm wheel 504 is fixedly sleeved on the lower outer side of the rotating rod 503. The worm wheel 504 and the worm gear 502 are designed to be meshed. Magnetic strips 505 are fixed inside the connecting plate 4 and inside the support plate 1.

[0020] The first lithium battery 6 at the upper end of the motor 501 is fixedly connected to the support plate 1. The first lithium battery 6 and the motor 501 correspond one-to-one. The first lithium battery 6 and the motor 501 are connected by wires. The top of the slide plate 2 is fixedly provided with a mounting plate 7. The mounting plate 7 has a stud 8 inside the thread. The stud 8 and the slide plate 2 are designed to be perpendicular to each other. The rotating plate 3 has a screw hole 9 integrally provided on the inner and outer sides. The screw hole 9 is a blind hole design. The screw hole 9 and the stud 8 are connected by threads for disassembly and assembly.

[0021] First, the two connecting plates 4 and the rotating plate 3 are parallel to each other with the support plate 1, so that the rotating plate 3 and the connecting plate 4 are in a retracted state. In addition, the magnetic strip 505 on the connecting plate 4 and the magnetic strip 505 on the support plate 1 are magnetically attracted to each other, so that the retracted connecting plate 4 and the rotating plate 3 are firmly connected to the support plate 1. This allows the staff to easily move the retracted device to the use area. When the device needs to be unfolded, the staff first moves the two support plates 1 in opposite directions, and then separates the magnetic strip 505 on the connecting plate 4 from the support plate 1. This makes the unfolded state of the rotating plate 3 and the connecting plate 4 perpendicular to the support plate 1. Then, the stud 8 is screwed into the screw hole 9 to lock the unfolded state of the rotating plate 3 and the connecting plate 4. Example 2

[0022] like Figure 1 , Figure 2 , Figure 4 As shown, a sealing strip 10 is fixedly provided at the end of the connecting plate 4 away from the screw hole 9. An exhaust hole 11 is integrally provided inside the connecting plate 4, and the interior of the exhaust hole 11 is connected to the interior of the connecting plate 4. A pump 12 for both pumping and venting is fixedly provided on the outer wall of the left side of the connecting plate 4. A connector 13 is fixedly provided at the rear end of the pump 12 and is fixedly inserted through the connecting plate 4. The interior of the connector 13 is connected to the interior of the exhaust hole 11 on the left side. A second lithium battery 14 is fixedly provided on the outer wall of the left side of the connecting plate 4 and is connected to the pump 12 by a wire. Springs 15 are fixedly provided at both ends of the outer side of the rotating plate 3. The end of the spring 15 away from the rotating plate 3 is fixedly connected to the connecting plate 4. The spring 15 and the exhaust hole 11 are offset from each other. The sealing strip 10 has a rectangular cross-section when viewed from the side. The center of the rectangular sealing strip 10 coincides with the center of the exhaust hole 11.

[0023] According to the operation method in Embodiment 1, when the unfolded state of the rotating plate 3 and the connecting plate 4 is locked, the state of the two connecting plates 4 being tightly fitted together is simultaneously locked. In addition, the exhaust holes 11 in the two connecting plates 4 are in a connected state. The sealing strip 10 seals the area where the two exhaust holes 11 are connected. The operator can turn on the motor 501. The motor 501 drives the worm gear 502 to drive the worm wheel 504 to rotate the rotating rod 503. Through the threaded transmission between the rotating rod 503 and the sliding plate 2, the sliding plate 2 drives the unfolded rotating plate 3 and the connecting plate 4 to be raised and lowered along the longitudinal direction of the support plate 1. In addition, the operator can turn on the air inflation function of the pump 12 to discharge the outside air into the connecting plate 4 through the exhaust hole 11 from the connector 13. This causes the inflation air to push the rotating plate 3, together with the sliding plate 2 and the support plate 1, to move along the outer direction, and the spring 15 deforms. In the above way, the support plate 1, the sliding plate 2, the rotating plate 3 and the connecting plate 4 can be matched and used with tunnels of different sizes.
