The main bevel gear 22 and the side bevel gear 21 in the driving mechanism 2 are meshed and connected to achieve efficient transmission, thereby driving the screw rod 5 to rotate, and then allowing the slide bar 6 to slide smoothly in the sleeve frame 4. This design effectively ensures the accuracy and flexibility of the support length adjustment. At the same time, the combination of the sleeve frame 4, the screw rod 5 and the slide bar 6 ensures the reliability of the support. The setting of the support assembly 7 can better adapt to the mine environment and provide stable support for the mine. In short, the structure has the advantages of high stability, convenient adjustment and strong adaptability.

[0026] refer to Figure 3 The adjustment mechanism 3 includes a fixing frame 31 and a limiting hole 32. The fixing frame 31 is fixedly installed in the middle of one side of the fixing frame 1. The fixing frame 31 is rotatably connected with a rotating shaft 33 inside. The limiting holes 32 are arranged in a ring shape with equal spacing and are opened in the middle of one side of the fixing frame 31. The end of the rotating shaft 33 is fixedly connected to the outer side of the main bevel gear 22. A rotating disk 34 is fixedly installed on the outer side of the rotating shaft 33. One end of the outer side of the rotating disk 34 is fixedly connected to a limiting assembly 35. The end of the limiting assembly 35 passes through the rotating disk 34 and is inserted into the inner side of the limiting hole 32. The frame 31 is fixed to the middle of one side of the fixed frame 1, providing stable support for the rotating shaft 33, so that the rotating shaft 33 can rotate smoothly to drive the main bevel gear 22 to realize power transmission. The limiting holes 32 are arranged in a ring with equal spacing, and cooperate with the limiting components 35 on the turntable 34. After adjustment, they can be accurately limited and fixed to ensure the stability of the supporting state. This design makes the adjustment operation flexible and reliable, and can quickly and accurately adjust and fix the supporting structure, thereby improving the convenience and safety of the entire mine auxiliary support structure during use.

[0027] refer to Figure 3The limiting assembly 35 includes a concave frame 351, which is fixedly installed at one end of the outer side of the rotating disk 34. The inner part of the concave frame 351 is fixedly connected to a limiting spring 352, and the end of the limiting spring 352 is fixedly installed with a limiting plate 353. The side of the limiting plate 353 close to the fixed frame 1 is fixedly connected to a limiting pin 354. The end of the limiting pin 354 penetrates the rotating disk 34 and is inserted into the inner side of the limiting hole 32. The concave frame 351 provides a stable installation foundation for the internal structure, and is tightly connected to the rotating disk 34 to ensure the overall stability. The limiting spring 352 is fixedly connected to the inner side of the limiting plate 353. The spring 352 gives the limit plate 353 elastic activity, so that the limit pin 354 can be flexibly plugged into or separated from the limit hole 32. This elastic mechanism can not only achieve reliable limit fixation when needed and ensure the stability of the adjusted state, but also can easily and quickly perform unlocking and adjustment. At the same time, this design is simple and effective, and has high reliability and durability in actual use. It provides important guarantees for the stable operation and convenient adjustment of the entire mine auxiliary support structure, can adapt to the complex and changeable mine working environment, and ensure the smooth progress of support operations.

[0028] refer to Figure 3 The outer end of the limit pin 354 away from the fixed frame 1 is fixedly installed with a connecting shaft 355, the outer end of the connecting shaft 355 passes through the concave frame 351 and is rotatably connected to a crank 356, and the outer surface of the crank 356 is fixedly connected to an arm cover. The setting of the connecting shaft 355 makes it easier to operate the limit pin 354 through the crank 356 to achieve its interactive action with the limit hole 32. The crank 356 provides a convenient fulcrum for the operation. By rotating the crank 356, the connecting shaft 355 and the limit pin 354 can be easily driven to move, thereby improving the efficiency and convenience of adjustment. The presence of the arm cover increases the comfort and stability of holding, allowing the operator to better apply force and control during use. This design not only increases The convenience and humanization of operation are enhanced, and the support structure can be quickly and accurately adjusted and fixed under various working conditions, which further improves the practicality and adaptability of the entire mine auxiliary support structure. During use, the crank handle 356 is held by hand to pull the connecting shaft 355 outward, and the connecting shaft 355 drives the limit pin 354 to disengage from the limit hole 32. At this time, the turntable 34 and the fixed frame 31 lose the lock, and the force of pulling outward is maintained. At the same time, the crank handle 356 is pulled to drive the turntable 34 to rotate. It is not necessary to remove the crank handle 356 and then rotate the turntable 34. After the pulling is completed, the crank handle 356 is released, and the limit spring 352 is reset to drive the limit pin 354 to be inserted into the corresponding limit hole 32 for limiting.

[0029] refer to Figure 1-Figure 2 and Figure 4The support assembly 7 includes a connecting plate 71, which is fixedly connected to the outer end of the slide rod 6. The outer end of the connecting plate 71 is fixedly connected to a hinge ball 72. The outer surface of the hinge ball 72 is rotatably connected to a fixing seat 73. The outer side of the fixing seat 73 is rotatably connected to a support plate 74. The connecting plate 71 effectively connects the slide rod 6 with other parts to ensure the transmission of force and the stability of the support. The setting of the hinge ball 72 enables the fixing seat 73 to rotate flexibly, so that the support plate 74 can adaptively adjust the angle according to actual conditions to better fit the inner wall of the mine, greatly improving the adaptability to different mine environments. The rotatable connection between the support plate 74 and the fixing seat 73 further enhances this adaptability, enabling the support plate 74 to flexibly cope with various complex mine surface conditions and ensure the reliability and stability of the support. Such a support assembly 7 is exquisitely designed and can play a good supporting effect in practical applications.

[0030] refer to Figure 4 , reserved grooves 75 are provided at equal intervals on the outer side of the fixing seat 73, and the shape of the reserved grooves 75 corresponds to the connecting plate 71, and mounting holes 76 are provided at the four corners of the support plate 74. The mounting holes 76 provided at the four corners of the support plate 74 provide convenience for further fixing the support plate 74 or connecting it with other components, thereby increasing its flexibility and versatility in use. At the same time, the reserved grooves 75 can increase the rotation range of the connecting plate 71, thereby improving the overall adjustment and adaptability of the device.

[0031] refer to Figure 1 The outer side of the support plate 74 is fixedly connected with anti-skid bevel teeth 77 at equal intervals, and the mounting holes 76 are set as countersunk holes. The anti-skid bevel teeth 77 at equal intervals on the outer side of the support plate 74 can enhance the friction between the contact surface, making the support more stable and reliable, and effectively preventing unstable situations such as sliding in the mine environment, thereby ensuring operational safety; and setting the mounting holes 76 as countersunk holes, on the one hand, can make the surface of the connected component after installation flush with the surface of the support plate 74, maintaining the flatness and aesthetics of the appearance, and on the other hand, it is also beneficial to avoid the connection component from causing scratches and other effects on the surrounding environment. At the same time, the design of the countersunk holes also provides a more stable structural foundation for installation and fixation.

[0032] Principle and advantages of use: By setting the support assembly 7, the device can be used to assist in adjusting the rotation of the screw rod 5 through the adjustment mechanism 3 during use. The rotation of the screw rod 5 can assist in driving the slide rod 6 to slide on the inner side of the sleeve frame 4. The sliding of the slide rod 6 can assist in driving the connecting plate 71 to move toward the outside. When the support plate 74 on the outside of the connecting plate 71 contacts the inner wall of the mine, due to the articulation design of the articulated ball 72 at the fixed seat 73, the support plate 74 can rotate adaptively at this time. At the same time, the connection plate 71 cooperates with the reserved groove 75 to improve the rotation adaptation of the articulated ball 72. The range enables the device to adapt according to the self-adaptive adjustment rotation at the inclined surface inside the mine during the support process, so that the device as a whole has a strong adaptability, and during use, the setting of the anti-slip bevel teeth 77 can increase the friction force on the outside of the support plate 74, and can improve the stability of the support plate 74 in fitting the inside of the mine, and due to the setting of the mounting hole 76, when stable installation is required, bolts or anchor rods can be inserted into the inner side of the mounting hole 76, so that the device can be stably supported inside the mine, which can improve the overall comprehensive stability of the device as a whole;

[0033] By setting the adjustment mechanism 3, the device can be moved outward by pulling the crank handle 356 during use. At this time, the crank handle 356 can pull the connecting shaft 355 to drive the limiting plate 353 to move outward. The limiting plate 353 moves outward to drive the limiting pin 354 to disengage from the limiting hole 32. The limiting hole 32 and the limiting pin 354 are separated from each other. At this time, the limit between the turntable 34 and the fixed frame 1 is lost. At this time, the crank handle 356 is pushed to drive the turntable 34 to rotate. The rotation of the turntable 34 can drive the rotating shaft 33 to rotate. The rotation of the rotating shaft 33 can drive the main bevel gear 22 to rotate, and the main bevel gear 22 is meshed with the side bevel gear 21. At this time, as the main bevel gear 22 rotates, the side bevel gear 21 can be driven The wheel 21 rotates, and the side bevel gear 21 rotates to synchronously drive the two sets of screw rods 5 to rotate. By rotating the two sets of screw rods 5, the slide rod 6 and the sleeve frame 4 can be assisted to slide against each other, and then the overall support length of the device can be adjusted. When the support length is adjusted, by loosening the crank handle 356, the limit spring 352 is reset to drive the limit pin 354 to be inserted into the inner side of the limit hole 32. At this time, the limit hole 32 and the limit pin 354 are mutually limited to fix the turntable 34, and then the side bevel gear 21 and the main bevel gear 22 can be locked and fixed, thereby locking the screw rod 5. It can be seen that the overall disassembly, assembly and maintenance of the device is relatively convenient, which can improve the adaptability and adjustment convenience of the device during overall use.
