Detailed Description
The invention is further described with reference to the following figures and detailed description.
Examples
Referring to fig. 1-13, the steel pipe support quick unloading device of the embodiment includes a buckle and an annular wedge pin, where the buckle includes an upper wedge ring 1 and a lower wedge ring 2 that are fastened up and down. Wherein:
the upper wedge-shaped ring 1 and the lower wedge-shaped ring 2 are identical in structure and comprise a circular ring body 3 and guide limiting blocks 4 arranged at the front edge and the rear edge of the circular ring body 3, and the side view of the circular ring body 3 is wedge-shaped. After the upper wedge-shaped ring 1 is buckled with the lower wedge-shaped ring 2, the guide limiting block 4 of the upper wedge-shaped ring 1 is malposed and occluded with the guide limiting block 4 of the lower wedge-shaped ring 2, and a wedge-shaped slot 5 is formed between the annular body 3 of the upper wedge-shaped ring 1 and the annular body 3 of the lower wedge-shaped ring 2.
The annular wedge pin is integrally in a round-angle rectangular shape and comprises a load end 6, an unloading end 7 and two connecting arms 8 arranged between the load end 6 and the unloading end 7, wherein the two connecting arms 8 are symmetrically arranged, and the side view of the two connecting arms is in a wedge shape. When the annular wedge pin is assembled with the ring buckle, two connecting arms 8 of the annular wedge pin are matched with the wedge-shaped slot 5, so that the upper wedge ring 1 can ascend and descend. The side walls of the annular wedge pin load end 6 are relatively high and the side walls of the unload end 7 are relatively short, wherein the maximum height of the load end 6 is greater than the maximum height of the wedge slot 5.
In order to ensure that the annular wedge pin can keep a load state when not loaded, the outer side wall of the load end 6 of the annular wedge pin is provided with a clamping groove 9, an arc-shaped clamp spring 10 is clamped in the clamping groove 9, and two ends of the arc-shaped clamp spring 10 are respectively clamped in clamping holes 11 formed in the two connecting arms 8. Two ends of the arc-shaped clamp spring 10 are respectively buckled with the guide limiting blocks 4 of the upper wedge-shaped ring 1 and the lower wedge-shaped ring 2, so that the annular wedge pin can keep a load state under the condition of no load.
The top surface and the bottom surface of the two connecting arms 8 of the annular wedge pin are correspondingly provided with bosses 12 for preventing the upper wedge ring 1 and the lower wedge ring 2 from sliding back to the unloading end 7 during bearing.
And an unloading knocking surface 13 is arranged on the outer side wall of the unloading end 7 of the annular wedge pin. When unloading, the unloading knocking surface 13 is knocked to move the annular wedge pin, so that quick unloading is realized.
In order to limit the maximum height of the upper wedge ring 1 moving upwards, an anti-falling stop 14 is arranged on one side of the upper edge of the guide limiting block 4. After the upper wedge-shaped ring 1 is buckled with the lower wedge-shaped ring 2, the anti-falling stop dog 14 on the guide limiting block 4 of the upper wedge-shaped ring 1 is positioned under the anti-falling stop dog 14 on the guide limiting block 4 of the lower wedge-shaped ring 2. With the two connecting arms 8 of the annular wedge pin being continuously inserted into the wedge-shaped slot 5, the upper wedge-shaped ring 1 is pushed to continuously move upwards, and when the upper wedge-shaped ring 1 moves upwards to the maximum height, the anti-disengaging stop 14 on the guiding limiting block 4 of the upper wedge-shaped ring 1 is abutted to the anti-disengaging stop 14 on the guiding limiting block 4 of the lower wedge-shaped ring 2.
As another embodiment of the present invention, a plurality of guiding stoppers 4 may be disposed on the periphery of the circular ring body 3, and a gap between two adjacent guiding stoppers 4 can accommodate the guiding stoppers 4 and the anti-falling stoppers 14 engaged with the guiding stoppers in a staggered manner.
The working principle of the invention is briefly described as follows:
the structure of the original steel pipe support is kept unchanged, and the quick unloading device is sleeved on the outer support pipe 17 between the G-shaped hook 15 and the adjusting nut 16.
When the quick unloading device is used, the loading end 6 of the annular wedge pin is pushed, the quick unloading device is in a loading state (refer to fig. 14), at the moment, two ends of the arc-shaped clamp spring 10 are respectively clamped with the guiding limiting blocks 4 of the upper wedge ring 1 and the lower wedge ring 2 (refer to fig. 1), and although the quick unloading device is not loaded at the moment, the annular wedge pin can still maintain the loading state. When the jacking is required, the adjusting nut 16 is rotated to enable the steel pipe support to jack the upper top surface, at the moment, the downward pressure of the top surface acts on the G-shaped hook 15 through the inner support pipe 18, and the G-shaped hook 15 presses on the upper wedge-shaped ring 1. After the top is formed, the unloading knocking surface 13 of the unloading end 7 of the annular wedge pin is knocked to enable the quick unloading device to be in an unloading state (refer to fig. 15), at the moment, the upper wedge ring 1 falls due to losing of the support of the annular wedge pin, the gap between the upper wedge ring 1 and the lower wedge ring 2 is reduced, meanwhile, the G-shaped hook 15 and the inner support pipe 18 fall due to losing of the support of the upper wedge ring 1, the jacking of the building template is released, and the building template is convenient to further dismantle.
The quick unloading device is simple in structure and convenient to operate, adopts a quick-release mode to replace a traditional thread mode to realize quick unloading of the steel pipe support, greatly reduces the labor intensity of construction workers, and improves the disassembling speed of the steel pipe support.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures made by using the contents of the specification and the drawings of the present invention can be directly or indirectly applied to other related technical fields, and are within the scope of the present invention.
