[0002] During coal mining operations, with the continuous increase in the depth of modern fully mechanized coal mining, the geological conditions become increasingly complex. Not only does the in-situ stress of the deep rock strata in the mine increase continuously, but the surrounding rock is easily damaged. Under the action of pressure, the surrounding rock is overly relaxed and prone to instability, resulting in excessive plastic deformation or loosening damage problems under the action of secondary stress. Therefore, support devices are needed.

[0003] After retrieval, the utility model patent with the publication (announcement) number of CN219492313U discloses a temporary support device for coal mining and excavation. Generally speaking, it includes two vertical plates, and an arc-shaped support plate is arranged above the two vertical plates. An adjustment groove is opened at the top of the vertical plate, and an adjustment seat fixedly connected to the arc-shaped support plate is slidably installed in the adjustment groove. When in use, it can adjust the height of the arc-shaped support plate, and can achieve the purpose of temporary support during coal mining and excavation in different scenarios. Through the cooperation of the support screw and the connecting rod, the arc-shaped support plate can be supported, thereby achieving the purpose of increasing the stability of the arc-shaped support plate. However, the above device still has certain deficiencies. For example, the above device is not easy to move, and it is time-consuming and laborious when handling and moving positions, etc. Moreover, it also requires manual height adjustment, and the process is also relatively cumbersome, with poor practicability. Therefore, we propose a temporary support device. Content of the Utility Model

[0026] Two bases 1;

[0027] Two moving mechanisms are respectively arranged on two bases 1. The moving mechanism includes a chute, two threaded shafts 2 and multiple pulleys 3. The chute is opened on the base 1. The two threaded shafts 2 are both rotatably connected through the base 1. The multiple pulleys 3 are all installed on the base 1. A slider 4 is slidably connected in the chute. Two threaded grooves are opened on the slider 4. The threaded shaft 2 is threadedly connected in the threaded groove. A turntable 5 is fixedly connected to the threaded shaft 2. A top plate 6 is fixedly connected to the slider 4. The pulleys 3 are used to facilitate people's movement. The threaded shafts 2, the slider 4, etc. are used to drive the top plate 6 to be fixed on the ground, play a supporting role, and are used to move and support and fix the overall device;

[0028] A supporting mechanism is arranged on two bases 1. The supporting mechanism includes two support frames 7, two motors 8 and four support cylinders 9. The two support frames 7 are respectively fixedly connected to the two bases 1. The two motors 8 are respectively installed on the two bases 1. The four support cylinders 9 are respectively fixedly connected to the two bases 1. A support column 10 is slidably connected in the support cylinder 9. A support plate 11 is fixedly connected to the four support columns 10. A support plate 12 is fixedly connected to the support plate 11. Two fixing blocks 13 are fixedly connected to the support plate 11 and the support plate 12. The output end of the motor 8 penetrates through the support frame 7 and is fixedly connected to a threaded column 14. An internally threaded cylinder 15 is threadedly sleeved on the threaded column 14. The internally threaded cylinder 15 is fixedly connected to the fixing block 13. The motor 8 is used to provide power. The threaded column 14, the internally threaded cylinder 15, etc. are used for height adjustment. The support plate 12 is used for support.

[0029] A plurality of limiting grooves are opened on the base 1. A control rod 16 is slidably connected through the turntable 5. One end of the control rod 16 is located in one of the limiting grooves, which is used to limit the turntable 5 and make the top plate 6 support better.

[0030] The four support cylinders 9 are grouped in pairs. Connecting rods 17 are fixedly connected to both of the two support cylinders 9. A stabilizing ring 18 is fixedly connected between the two connecting rods 17. The stabilizing ring 18 is slidably sleeved on the internally threaded cylinder 15, which is used to improve the stability of the internally threaded cylinder 15.

[0031] Two stabilizing rods 19 are fixedly connected in the chute. Two stabilizing grooves are opened on the slider 4. The stabilizing rods 19 are located in the stabilizing grooves, which is used to improve the stability of the slider 4.

[0032] A plurality of fixing rods 20 are fixedly connected between the support plate 11 and the support plate 12, which are used to support the support plate 12.

[0033] It should be further noted that the motor 8 in this embodiment is a conventional device well-known to those skilled in the art and can be purchased on the market. The model can be selected according to actual needs or customized. In this patent, we only use it without improving its structure and function. For those skilled in the art, its setting method, installation method, and electrical connection method only need to be debugged according to the requirements of its user manual, so it will not be elaborated here. Moreover, the motor 8 is provided with a matching control switch, and the installation position of the control switch is selected according to actual use requirements for the convenience of operation and control by the operator.

[0034] In summary, the working principle and process of this temporary support device are as follows: during use, first, the temporary support device is pushed to the required location through the pulley 3. The pulley 3 facilitates the movement of the device by people, improving its practicability. Then, the positive and negative rotation circuits of the motor 8 are connected according to the corresponding manual. Then, people pull out a control rod 16 with each hand, causing the two turntables 5 to rotate simultaneously, which is convenient for the turntables 5 to drive the threaded shaft 2 to rotate. The threaded shaft 2 drives the slider 4 and the top plate 6 to descend. The top plate 6 abuts against the ground. Then, people release the control rod 16 and let the control rod 16 enter other limit slots. At this time, people start the motor 8. The motor 8 drives the threaded column 14 to rotate, and the threaded column 14 drives the internal threaded cylinder 15 to rise and fall. The internal threaded cylinder 15 drives the support plate 11, the support plate 12, etc. to rise and fall. At the same time, the support column 10 also rises and falls and slides in the support cylinder 9, improving the stability of the support plate 11 and the support plate 12. In this way, the height adjustment is completed, saving manpower, avoiding manual operation, and improving practicability.

[0035] The above embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
