Utility Model Content

[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: A temporary mining support platform with a fall protection structure, including a bottom support platform 1 and a top support platform 2, and a lifting structure is installed between the bottom support platform 1 and the top support platform 2; the lifting structure includes a support rod 7 between the bottom support platform 1 and the top support platform 2, and the end of the support rod 7 away from the top support platform 2 is rotatably connected to the end of the bottom support platform 1, and the end of the support rod 7 away from the bottom support platform 1 is installed at the bottom of the top support platform 2, and two support rods 7 are symmetrically distributed between the bottom support platform 1 and the top support platform 2, and the bottom support platform 1, the top support platform 2 and the support rod 7 are distributed in a trapezoidal structure; there are two bottom support platforms 1 and two top support platforms 2, and an intercepting net 3 is fixedly connected between the two top support platforms 2, and a rotating shaft 4 is provided in the middle of the bottom support platform 1 and the top support platform 2; a guide rail 5 is fixedly connected to the bottom of the top support platform 2, and a slider 6 is slidably connected to the outside of the guide rail 5, and the slider 6 is slidably connected to the outside of the guide rail 5.

[0026] Before the equipment is transported, the bottom support platform 1 and the top support platform 2 are folded, and the distance between them is minimal. At this time, one end of the support rod 7 is attached to the end of the bottom support platform 1, and the other end is attached to the bottom of the top support platform 2. The lifting mechanism is folded to the most compact state, and the intercepting net 3 between the two top support platforms 2 is also folded. The entire device has a columnar structure, occupies little space, and is easy to transport to the working area of ​​the mine.

[0027] The bottom support platform 1 of the device is placed on both sides of the mine shaft. The placement angle of the bottom support platform is adjusted according to the terrain of the mine shaft to ensure the initial stability of the device as a whole. By rotating the lead screw 10 in the lifting mechanism, the support rod 7 is driven to move upward. During this process, one end of the support rod 7 moves away from the bottom support platform 1 and rotates around the end of the bottom support platform 1. At the same time, the other end of the support rod 7 slides along the slider 6 on the outside of the guide rail 5, so that it moves at the bottom of the top support platform 2.

[0028] As the lead screw 10 rotates, the support rod 7 gradually unfolds and widens the distance between the bottom support platform 1 and the top support platform 2. The angle between the support rod 7 and the bottom support platform 1 and the top support platform 2 continuously increases, making the device form a stable support trapezoidal structure. The bottom support platform 1 and the top support platform 2 are both equipped with a rotating shaft 4 in the middle, which can rotate to a certain extent. This feature allows the device to adapt to the complex terrain and shape inside the mine, thereby improving the applicability of the device.

[0029] After the two top support platforms 2 are raised to a sufficient height, the top interception net 3 will be fully deployed between the two top support platforms 2, forming a barrier covering the top of the mine, preventing loose rocks from falling from the top of the mine, thereby effectively preventing accidents and ensuring the safety of workers.

[0030] Example 2: Based on Example 1, the following structure is also disclosed: Preferably, the support rod 7 is provided with a mounting groove 8 in the middle, and a rotating block 9 is rotatably connected inside the mounting groove 8, and a lead screw 10 is threadedly connected inside the rotating block 9; the threads at both ends of the lead screw 10 are opposite in direction, and a universal joint 11 is provided in the middle of the lead screw 10, and the universal joint 11 and the rotating shaft 4 are aligned with each other; two symmetrically distributed handles 12 are rotatably connected to the end of the lead screw 10 away from the universal joint 11; a snap groove 13 is provided at the end of the handle 12 away from the lead screw 10, and the handle 12 and the lead screw 10 are magnetically attracted to each other.

[0031] The support rod 7 has a mounting groove 8 in the middle, and a rotating block 9 is rotatably connected in the mounting groove. The center of the rotating block 9 has a thread, which cooperates with the lead screw 10 located inside the mounting groove. The lead screw 10 adopts a design with opposite thread directions at both ends to ensure that the rotating block 9 can be pushed to move in the opposite direction at the same time when rotating.

[0032] A universal joint 11 is provided in the middle of the lead screw to ensure that the lead screw 10 can flexibly adjust its running direction and align with the rotating shaft 4 during operation. Both ends of the lead screw 10 are operated by handles 12. The end of the handle 12 away from the lead screw has a groove 13. The handle 12 is rotated through the groove 13 until the handle 12 and the lead screw 10 are perpendicular to each other.

[0033] The operator rotates the handle 12 to rotate the lead screw 10. Since the threads at both ends of the lead screw are in opposite directions, when the lead screw rotates, it will push the two rotating blocks 9 to move in opposite directions. The movement of the rotating blocks 9 directly drives the support rod 7 to expand outward. At the same time, the lower end of the support rod 7 rotates around the end of the bottom support platform 1. As the lead screw 10 continues to rotate, the angle between the support rod 7 and the bottom support platform 1 and the top support platform 2 gradually increases. When the support rod 7 is fully extended, the device forms a stable trapezoidal support structure.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium.
