[0043] Example 1

[0044] like Figures 1 to 4 As shown, this utility model discloses a rapid hoisting device for prefabricated fence bases, applicable to scenarios such as construction site fencing and construction enclosure, aiming to improve the hoisting efficiency and safety of prefabricated fence bases. It includes a first clamping arm 100, a second clamping arm 200, and a first hinge portion 300. The middle portion of the first clamping arm 100 is hinged to the middle portion of the second clamping arm 200 via the first hinge portion 300.

[0045] One end of the first clamping arm 100 is a first lifting end 101 and the other end is a first clamping end 102. One end of the second clamping arm 200 is a second lifting end 201 and the other end is a second clamping end 202. The end of the first clamping end 102 is provided with a first clamping component, and the end of the second clamping end 202 is provided with a second clamping component that works in conjunction with the first clamping component.

[0046] The prefabricated base of the enclosure is quickly hoisted by using a second clamping component in conjunction with the first clamping component.

[0047] like Figures 1 to 2 As shown, in this embodiment, the first clamping assembly includes a first connecting part 104. One end of the first connecting part 104 is hinged to the end of the first clamping end 102 through a second hinge part 103, and the other end of the first connecting part 104 is provided with a first clamping pad 105.

[0048] A first lower connecting ear 106 is provided on the upper surface of the middle part of the first connecting part 104, and a first upper connecting ear 107 is provided on the corresponding wall surface of the first clamping arm 100 near the first clamping end 102. The first lower connecting ear 106 is connected to the first upper connecting ear 107 by a first spring 108.

[0049] A second lower connecting ear 206 is provided on the upper surface of the middle part of the second connecting part 204, and a second upper connecting ear 207 is provided on the corresponding wall surface of the second clamping arm 200 near the second clamping end 202. The second lower connecting ear 206 is connected to the second upper connecting ear 207 by a second spring 208.

[0050] Through the design of the second hinge 103, the first connecting part 104, the first clamping pad 105, the first lower connecting ear 106, the first upper connecting ear 107, and the first spring 108, and through the design of the third hinge 203, the second connecting part 204, the second clamping pad 205, the second lower connecting ear 206, the second upper connecting ear 207, and the second spring 208, it is ensured that the first clamping pad 105 and the second clamping pad 205 can correspond to each other and smoothly face the two side walls of the prefabricated base of the enclosure during the clamping process, until they are tightly fitted and clamped. This avoids the possibility of the base tilting or falling off.

[0051] like Figures 1 to 2 As shown, in this embodiment, a plurality of through first pin holes 109 are provided on the side wall of the first clamping arm 100, and are symmetrically distributed on both sides of the first hinge portion 300.

[0052] The second clamping arm 200 has multiple through second pin holes 209 on its side wall surface, which are symmetrically distributed on both sides of the first hinge portion 300.

[0053] When the rapid hoisting device is in the retracted state, each of the first pin holes 109 is aligned with a corresponding second pin hole 209, and each of the first pin holes 109 can be locked to the corresponding second pin hole 209 by a movable pin.

[0054] The design of the first pin hole 109 and the second pin hole 209 enables the quick hoisting device to be better retracted and locked.

[0055] like Figures 1 to 2 As shown, in this embodiment, the first hinge portion 300 is a movable bearing or a rotating shaft. By designing the first hinge portion 300 as a movable bearing or a rotating shaft, it is ensured that the first clamping arm 100 and the second clamping arm 200 can cooperate to form a clamping structure. This adapts to prefabricated enclosure bases of different sizes and weights, expanding the application range.

[0056] like Figures 1 to 2 As shown, in this embodiment, both the first clamping end 102 and the second clamping end 202 are "L" shaped, and the first clamping end 102 and the second clamping end 202 are arranged symmetrically with respect to the first hinge portion 300.

[0057] With the first clamping end 102 and the second clamping end 202 both being "L"-shaped, and the first clamping end 102 and the second clamping end 202 being symmetrically arranged with the first hinge portion 300, the first clamping end 102 cooperates with the second hinge portion 103, the first connecting portion 104, the first clamping pad 105, the first lower connecting ear 106, the first upper connecting ear 107 and the first spring 108, and the second clamping end 202 cooperates with the third hinge portion 203, the second connecting portion 204, the second clamping pad 205, the second lower connecting ear 206, the second upper connecting ear 207 and the second spring 208, further ensuring that the first clamping pad 105 and the second clamping pad 205 can correspond to each other and smoothly face the two side walls of the prefabricated base of the enclosure during the clamping process, until they are tightly fitted and clamped.

[0058] like Figures 1 to 4 As shown, in this embodiment, both the first lifting end 101 and the second lifting end 201 are provided with lifting holes. This design, where both the first lifting end 101 and the second lifting end 201 are provided with lifting holes, facilitates the connection of the wire rope of the lifting equipment to them.

[0059] like Figures 1 to 4 As shown, in this embodiment, the back of the first clamping arm 100 near the first clamping end 102 has a first adjustment cavity 401 extending in the width direction, and a first moving block 402 is slidably connected inside the first adjustment cavity 401.

[0060] The top of the first movable block 402 is provided with a first lifting lug 406.

[0061] The first movable block 402 has a first through hole in its middle. The outer wall of the first clamping arm 100 has a plurality of first fixing holes 404 that are evenly spaced along the length of the first adjusting cavity 401 and match the first through hole. The first through hole and the first fixing hole 404 are locked together by a first fixing member 405.

[0062] The bottom of the first moving block 402 is provided with a first transition block 403, the top surface of the first transition block 403 is in contact with the outer bottom surface of the first adjusting cavity 401, and the bottom surface of the first fixing hole 404 is fixedly connected to the first upper connecting ear 107.

[0063] The second clamping arm 200 has a second adjusting cavity 501 extending through the width direction on its back side near the second clamping end 202. A second moving block 502 is slidably connected inside the second adjusting cavity 501.

[0064] The top of the second moving block 502 is provided with a second lifting lug 506.

[0065] The second moving block 502 has a second through hole in its middle. The outer wall of the second clamping arm 200 has a plurality of second fixing holes 504 that are evenly spaced along the length of the second adjusting cavity 501 and match the second through hole. The second through hole and the second fixing hole 504 are locked together by a second fixing member 505.

[0066] The bottom of the second moving block 502 is provided with a second transition block 503. The top surface of the second transition block 503 is in contact with the outer bottom surface of the second adjusting cavity 501, and the bottom surface of the second fixing hole 504 is fixedly connected to the second upper connecting ear 207.

[0067] Through the design of the first adjusting cavity 401, the first moving block 402, the first transition block 403, the first fixing hole 404, the first fixing member 405, and the first lifting lug 406, and through the design of the second adjusting cavity 501, the second moving block 502, the second transition block 503, the second fixing hole 504, the second fixing member 505, and the second lifting lug 506, the first upper connecting lug 107 and the second upper connecting lug 207 can be in a sliding and adjustable state, and can also be in a locked state, thereby indirectly adjusting the rotation state of the first connecting part 104 and the second connecting part 204 to achieve a more suitable clamping state.

[0068] Use external equipment to hold the first lifting lug 406 (or a steel bar), then remove the first fixing part 405. Then, with the external equipment pulling (two operators lift the steel bar to move), the first moving block 402 slides along the length of the first adjusting cavity 401 in the first adjusting cavity 401 until it reaches the position of the next first fixing hole 404. When the position of the first connecting part 104 is also basically adjusted, insert the first fixing part 405 (e.g., countersunk bolt and nut) into the first fixing hole 404 and the first through hole and lock it. Then remove the external equipment from the first lifting lug 406.

[0069] Using external equipment to hold the second lifting lug 506 (or a steel bar), remove the second fixing part 505. Then, with the external equipment pulling (two operators lifting the steel bar), the second moving block 502 slides along the length of the second adjusting cavity 501 until it reaches the position of the next first fixing hole 404. When the position of the second connecting part 204 is also basically adjusted, insert the second fixing part 505 (e.g., countersunk bolt and nut) into this first fixing hole 404 and the first through hole and lock it. Remove the external equipment from the second lifting lug 506. The focus is on fine-tuning to compensate for the spring after a period of use. When fine-tuning cannot be performed using the above structure, the first spring 108 and the second spring 208 can be replaced.

[0070] All of the aforementioned hinge positions are rotatable and can be installed using existing mature hinge connection technology. A wear-resistant and anti-slip layer made of wear-resistant and anti-slip material is provided on the facing surfaces of both the first clamping pad 105 and the second clamping pad 205.

[0071] Working principle:

[0072] During the hoisting process, firstly, the first hoisting ends 101 at both ends of the retracted hoisting device are connected to the existing mature hoisting equipment wire ropes. The movable pin is removed from the second pin hole 209. Then, the first clamping pad 105 and the second clamping pad 205 are placed at the center (center of gravity) of the precast component to be hoisted (i.e., the precast base of the enclosure). The hoisting equipment is started, causing the first hoisting ends 101 and 201 to be slowly raised. Using the first hinge 300 as the rotation center, the gravity of the precast component to be hoisted tightly connects the rapid hoisting device of this invention to the precast component (the precast component is clamped by the first clamping pad 105 and the second clamping pad 205) until the precast component is hoisted to the predetermined position. Under safe conditions, the rapid hoisting device is released, allowing it to retract (e.g., ...). Figure 3 Then insert the movable pin again, and wait until the next precast component is hoisted before unloading it. Repeat this process.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
