Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, in particular to a hoisting auxiliary hoisting device which is convenient for turning over a concrete prefabricated wall panel. Background Art

[0002] During the construction process, in order to save construction time, the concrete slabs in the structure are often prefabricated, and the hoisting operation is carried out after the concrete reaches the designed strength. The traditional construction process is to reserve steel bar lifting rings on the prefabricated concrete slabs. The lifting rings are constructed together with the steel bars of the prefabricated concrete slabs. The bottom of the lifting rings is poured in the concrete, and the concrete slabs are lifted by the lifting equipment and the lifting rings.

[0003] However, when the concrete slab lifting equipment in the prior art lifts the concrete slab, the entire load-bearing weight of the concrete slab depends entirely on the lifting ring. When the hook and the lifting ring on one side become loose, the entire concrete slab will quickly tilt to the other side and swing violently, causing the steel wire to break, posing a safety hazard. In order to solve the above problems, we propose a lifting auxiliary sling that is convenient for flipping the concrete prefabricated wall panel to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a lifting auxiliary hoist that is convenient for flipping over prefabricated concrete wall panels. By coordinating the fixing assembly and the driving assembly, the utility model solves the problem that the concrete slab lifting equipment in the prior art lacks a protective function and the risk of the concrete slab easily falling occurs when the lifting is unbalanced.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a hoisting auxiliary hoist for facilitating the flipping of a concrete prefabricated wall panel, comprising a horizontal frame, both sides of the bottom of the horizontal frame are fixedly connected with a first hook, and the top of the horizontal frame is provided with a second hook; and

[0017] 1. The utility model can move two groups of clamping plates to both sides of the concrete slab through the setting of the fixing components, limit the two sides of the concrete slab, and limit the left and right tilting of the concrete slab when one group of first hooks is unhooked from the concrete slab, so as to avoid the concrete slab from deflecting and shaking when losing the supporting force at one end, thereby improving the safety of hoisting the concrete slab.

[0018] 2. Through the setting of the driving component, the utility model can transmit the tension of a single set of steel cables to two sets of clamping plates when the winding wheel reels the steel cables, thereby realizing the relative movement of the two sets of clamping plates and fixing the concrete slab.

[0031] A fixing assembly 2, which is disposed at the bottom of the horizontal frame 1, and includes a support column 201, which is fixed to the bottom of the horizontal frame 1, a support tube 202 is fixedly connected to the bottom of the support column 201, clamping plates 203 are disposed on both sides of the support tube 202, and a sliding rod 204 is fixedly connected to the opposite side of the clamping plate 203; and

A winding wheel 302 is fixedly connected to the rear side of the driving motor 301 . A steel cable 303 is fixedly connected to the surface of the winding wheel 302 .

[0033] Specifically: the first hook 101 is divided into two groups, which can cooperate with the hanging ring on the top of the concrete slab to bear the weight of the concrete slab. The second hook 102 and the first hook 101 are both movably connected with anti-drop pins. When the hanging rope is pressed into the second hook 102 and the first hook 101, the anti-drop pin prevents the hanging rope from detaching, thereby improving the connection stability. Specific embodiment 2

[0035] See also Figure 1-6 On the basis of the specific embodiment 1, the bottom of the steel cable rope 303 is divided into two groups, both ends of the bottom of the steel cable rope 303 are fixedly connected to the clamping plate 203, the opposite side of the slide rod 204 penetrates into the support tube 202 and is fixedly connected with a slider, the slider is slidably connected to the inner wall of the support tube 202, and a spring 4 is sleeved on the surface of the slide rod 204, and both ends of the spring 4 are fixedly connected to the support tube 202 and the clamping plate 203 respectively.

[0036] Specifically: the steel cable rope 303 can transmit the traction force of the driving motor 301. The driving motor 301 has a self-locking function. After the steel cable rope 303 is wound, the winding length can be fixed to achieve the fixing effect on the position of the clamping plate 203. The steel cable rope 303 is composed of multiple groups of steel wires. At its bottom, the wound steel wire rope is divided into two to achieve the effect of dispersing the pulling force. The spring 4 has an elastic effect and can reset the clamping plate 203. Specific embodiment three

[0038] See also Figure 1-6 On the basis of the first and second specific embodiments, support wheels 5 are sleeved on both sides of the steel cable rope 303, the front side of the support wheel 5 is fixedly connected to the support tube 202, the front side of the winding wheel 302 is movably connected to a bearing seat 6, the bottom of the bearing seat 6 is fixedly connected to the cross frame 1, the bottom of the second hook 102 is fixedly connected to a support sleeve 7, the inside of the support sleeve 7 is movably connected to a disc 8, the bottom of the disc 8 is fixedly connected to a traction rope 9, and the bottom of the traction rope 9 is fixedly connected to the cross frame 1.

[0040] The working principle of the utility model is as follows: the staff connects with the external traction equipment through the second hook 102, and then connects with the hanging ring on the top of the concrete slab through the first hook 101 to realize the lifting of the concrete slab, and then starts the driving motor 301 through the external controller, and the driving motor 301 cooperates with the winding wheel 302 to wind up the steel cable 303, and the two ends of the bottom of the steel cable 303 respectively pull the two groups of clamping plates 203 to move, and the two groups of clamping plates 203 move relatively and fit the concrete slab to clamp and fix the concrete slab. When one of the two groups of first hooks 101 loses its force, the clamping plate 203 can be used to limit the tilting of the concrete slab, so that the concrete slab remains stable and the stability during lifting is improved. The disc 8 slides inside the support sleeve 7, and when the concrete slab moves to the specified position, the cross frame 1 can maintain a rotational connection with the second hook 102, which is convenient for the staff to manually push the concrete slab to tilt and adjust the installation position to realize the flipping effect.
