The sleeve 3 is provided with multiple sets of adjustment holes 4. The snap-fit ​​rod 6 can pass through the mating sleeve 5 and different adjustment holes 4 to quickly snap-fit ​​with the snap-fit ​​tube 7. By selecting different adjustment holes 4, the sleeve 3 can be extended and retracted in the sleeve 2, thereby adjusting the width and position of the base frame 1 and increasing the applicability of the device.

[0032] The locking auxiliary mechanism includes a limiting ring 13, a rotating block 14, a spring rod 15, and a mating hole 16. The limiting ring 13 is rotatably mounted on the outer wall of the locking tube 7. The toothed ring 12 is mounted on the top end of the limiting ring 13.

The threaded ring 22 causes the clamping ring 23 to press the rotating tooth 11, thereby achieving stable clamping.

[0034] Please see Figures 1-5 As a supplementary embodiment of a support and unloading device for a single-layer hyperbolic box-shaped reticulated roof, which includes a bottom adjustment mechanism, a fixing and locking mechanism, and a locking auxiliary mechanism: the base frame 1 is symmetrically arranged and connected by the bottom adjustment mechanism. A side frame 17 is installed on one side of the top end of the base frame 1, and a transverse sliding screw assembly 401 is installed on the side frame 17. A lifting screw assembly 18 is installed on the transverse sliding screw assembly 401, and an installation sleeve 19 is installed on the lifting screw assembly 18. A support column 20 is installed on the 19, and a buffer block 21 is installed at one end of the support column 20. The buffer block 21 is in contact with and supported by the single-layer hyperbolic box-shaped reticulated roof. A threaded ring 22 is threadedly connected to the outer wall of the clamping pipe 7, and a clamping ring 23 is installed at the bottom end of the threaded ring 22. The clamping ring 23 can press the side of the rotating tooth 11 to fix the rotating tooth 11. Guide blocks 24 are installed on both sides of the screw rod frame 10, and the guide blocks 24 are directionally slidable on the side wall of the clamping pipe 7.

[0035] More specifically, the base frame 1 is symmetrically set and fixed on the ground, and the symmetrical base frames 1 are connected by a bottom adjustment mechanism. The specific operation is to select a suitable adjustment hole 4 by extending and retracting the sleeve 3 inside the sleeve 2, and quickly snapping the snap rod 6 with the snap tube 7 to adjust the width and position of the base frame 1. A side frame 17 is installed on one side of the top end of the base frame 1, and a transverse screw assembly 401 is installed on the side frame 17. A buffer block 21 is installed at one end of the support column 20. The buffer block 21 contacts the single-layer hyperbolic box-section grid roof and provides support. By meshing the rotating tooth 11 and the toothed ring 12, the screw frame 10 is driven to rotate, so that the screw frame 10 extends into or away from the slot 8, thereby fixing or releasing the snap rod 6. The threaded ring 22 is threadedly connected to the outer wall of the snap tube 7, and the clamping ring 23 presses the side of the rotating tooth 11 to ensure that the rotating tooth 11 is fixed, thereby achieving stable support and unloading of the single-layer hyperbolic box-section grid roof.

[0036] In summary, during the use or operation of the overall equipment: when the bottom adjustment mechanism is required, the fixed tube is fixedly installed at one end of the base frame 1, and the sleeve 3 is fixedly installed at the other end of the fixed tube, extending into the interior of the sleeve 2. A mating sleeve 5 is installed at one end of the sleeve 2, and a clamping tube 7 is fixedly installed at one end of the mating sleeve 5. The sleeve 3 is provided with multiple sets of adjustment holes 4. The clamping rod 6 can pass through the mating sleeve 5 and different adjustment holes 4 to quickly engage with the clamping tube 7. By selecting different adjustment holes 4, the sleeve 3 can be extended or retracted within the sleeve 2, thereby adjusting the width and position of the base frame 1 and increasing the applicability of the device.

[0037] When the locking mechanism needs to be fixed during operation, the locking groove 8 is set on the side wall of the locking rod 6, the rotating sleeve 9 is laterally limited and rotated on the outer wall of the locking tube 7, the lead screw frame 10 is threadedly connected to the inner wall of the rotating sleeve 9, the rotating tooth 11 is installed at one end of the rotating sleeve 9, the toothed ring 12 is limited and rotated on the outer wall of the locking tube 7 and meshes with the rotating tooth 11. When the rotating tooth 11 rotates, it drives the toothed ring 12 and the lead screw frame 10 to rotate together, so that the lead screw frame 10 extends into or away from the locking groove 8, thereby realizing the fixing and release of the locking rod 6, which facilitates the quick installation and disassembly of the sleeve 3 and the sleeve 2.

[0038] When the locking auxiliary mechanism is in operation, the limiting ring 13 is mounted on the outer wall of the locking tube 7 to limit rotation, the toothed ring 12 is mounted on the top end of the limiting ring 13, the rotating block 14 is mounted on the bottom end of the limiting ring 13, the spring rod 15 is mounted on the rotating block 14, and the mating hole 16 is arranged in a ring on the outer wall of the locking tube 7. The spring rod 15 can extend into different mating holes 16 to make the limiting ring 13 and the toothed ring 12 rotate stably. The rotation of the toothed ring 12 drives the rotating tooth 11 to rotate, which in turn drives the rotating sleeve 9 and the lead screw frame 10 to rotate, ensuring that the lead screw frame 10 stably extends into or pulls out of the locking groove 8. The threaded ring 22 makes the clamping ring 23 press the rotating tooth 11 to achieve stable locking.

[0039] The base frame 1 is symmetrically set and fixed on the ground. The symmetrical base frames 1 are connected by the bottom adjustment mechanism. Specifically, the expansion and contraction of the sleeve 3 within the sleeve 2 is used to select the appropriate adjustment hole 4, and the snap-fit ​​rod 6 is quickly snapped into the snap-fit ​​tube 7 to adjust the width and position of the base frame 1. A side frame 17 is installed on one side of the top end of the base frame 1, and a transverse screw assembly 401 is installed on the side frame 17. A buffer block 21 is installed at one end of the support column 20. The buffer block 21 contacts the single-layer hyperbolic box-section grid roof to provide support. Through the meshing of the rotating tooth 11 and the toothed ring 12, the screw frame 10 is driven to rotate, so that the screw frame 10 extends into or away from the slot 8, thereby fixing or releasing the snap-fit ​​rod 6. The threaded ring 22 is threadedly connected to the outer wall of the snap-fit ​​tube 7, and the clamping ring 23 clamps the side of the rotating tooth 11 to ensure that the rotating tooth 11 is fixed, thereby achieving stable support and unloading of the single-layer hyperbolic box-section grid roof.
