Description

Technical Field

[0001] The utility model relates to the technical field of component hoisting, in particular to a hoisting device for prefabricated components of assembled buildings. Background Art

[0002] Prefabricated components are building components made in advance in factories using concrete as the basic material. They include beams, slabs, columns and building decoration accessories, etc. They are assembled on the construction site. At present, most of them are assembled using lifting equipment.

[0003] In the prior art, for example, a hoisting device for assembled prefabricated building components disclosed in publication number CN214326899U records: by providing an extension mechanism, a motor is used to drive the rotation of the rotating shaft, and a first load-bearing frame, a second load-bearing frame, a threaded rod, a rotating bearing and a sliding block are coordinated, so that the hoisting device can be conveniently adjusted according to the size of the prefabricated building components before hoisting, which greatly avoids the safety hazards caused by the left and right shaking of the prefabricated building components during hoisting, making the operation safer.

[0004] In actual use, when the equipment is clamping prefabricated components, it is necessary to start the cylinder on one side, push the prefabricated components to the other side, and clamp the prefabricated components with a load-bearing frame and a push plate. Some thinner prefabricated components will tilt on one side when clamped by this equipment, and the one-sided tilt can easily cause accidents in which the prefabricated components fall. In addition, when the lifting height is too high, it is difficult for the entire equipment to avoid shaking during the lifting process. The rotation of the equipment and the influence of wind will cause the equipment to shake, and the clamping surface of the lifting equipment lacks support and blocking structures in the vertical direction. When shaking occurs, the friction force of the clamping surface alone cannot maintain the stability of the prefabricated components, which will cause the prefabricated components to fall during the shaking, posing a safety hazard. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The problem of unilateral tilt of the equipment when clamping some prefabricated components is solved; and the problem of failure to keep the position of the internal prefabricated components stable when the equipment shakes is solved.

[0007] (II) Technical solution

[0008] To achieve the above object, the utility model provides the following technical solution: a hoisting device for prefabricated components of an assembled building, comprising a bearing plate, one end of which is provided with a threaded groove, and the other end of which is fixedly connected to a limit ring;

[0009] It also includes a clamping structure arranged on the outside of the bearing plate and having hoisting and clamping functions;

[0010] The clamping structure includes a central end fixedly connected to the outside of the bearing plate, a cylinder fixedly connected to the inside of the central end, a clamping plate arranged on the telescopic rod of the cylinder, and a sliding block arranged at the bottom of the clamping plate.

[0011] Preferably, one side of the central end is fixedly connected to a limiting rod, and one side of the limiting rod is fixedly connected to a blocking block.

[0012] Preferably, a lifting ring is fixedly connected to the upper side of the central end.

[0013] Preferably, a slide groove is provided on the inner side of the carrying plate, and a slot is provided on the outer side of the carrying plate.

[0014] Preferably, a screw rod is provided on the inner side of the bearing plate, and a stabilizing structure is provided on the outer side of the bearing plate.

[0015] Preferably, the stabilizing structure includes a latch plugged into the outer side of the bearing plate, an L-shaped baffle fixedly connected to the latch, a buffer rod evenly arranged on one side of the L-shaped baffle, and a buffer pad fixedly connected to the buffer rod.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a hoisting device for prefabricated components of assembled buildings, which has the following beneficial effects:

[0018] 1. Under the action of the clamping structure, the original unilateral pressure clamping is changed to bidirectional pressure clamping. While the clamping itself is more stable, it also keeps the prefabricated components in the center of the equipment during transportation. Therefore, the overall device will not tilt on one side, ensuring the stability of the position of the device itself and the prefabricated components and increasing construction safety.

[0019] 2. The use of a stable structure allows the vertical direction of the clamping direction of the prefabricated components to be equally strong. Even if the device and the prefabricated components shake during transportation, the combination of the buffer pad and the buffer rod can always provide support for the prefabricated components. Under the premise of not causing impact damage to the prefabricated components, it can ensure that the prefabricated components do not slip in the vertical direction, thereby reducing safety hazards.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a lifting device for prefabricated components of assembled buildings, including a bearing plate 1, a thread groove 11 is provided at one end of the bearing plate 1, a limiting ring 12 is fixedly connected to the other end of the bearing plate 1, the inner thread of the thread groove 11 is connected to a screw rod 3, and a motor is connected to the side of the screw rod 3 close to the limiting ring 12 of the other bearing plate 1, and the screw rod 3 is located on the inner side of the limiting ring 12 of the other bearing plate 1, the limiting ring 12 is not connected to the screw rod 3, the limiting ring 12 is sleeved on the screw rod 3, and the limiting ring 12 can be translated along the screw rod 3, so that under the action of the two screw rods 3, the two bearing plates 1 can move toward each other;

[0028] It also includes a clamping structure arranged on the outside of the bearing plate 1 and having hoisting and clamping functions;

[0029] The clamping structure includes a central end 21 fixedly connected to the outside of the bearing plate 1, a cylinder 22 fixedly connected to the inside of the central end 21, the cylinder 22 has a telescopic rod directed toward the bearing plate 1, and a clamping plate 23 arranged on the telescopic rod of the cylinder 22. The clamping plate 23 is made of a material with a large friction coefficient with the prefabricated component, and a slider 24 is arranged at the lower part of the clamping plate 23, and the slider 24 can slide in the slide groove 13.

[0030] A limiting rod 25 is fixedly connected to one side of the central end 21. The central ends 21 on different supporting plates 1 are provided with square holes. The positions of the square holes correspond to the positions of the limiting rods 25 on the central ends 21 on different sides, and the limiting rods 25 can pass through. A blocking block 26 is fixedly connected to one side of the limiting rod 25. The blocking block 26 can ensure that the limiting rod 25 does not leave the parallel central ends 21 on different sides.

[0031] A lifting ring 27 is fixedly connected to the upper side of the central end 21, and the lifting ring 27 can be connected to a device responsible for raising the height of the lifting equipment.

[0032] A sliding groove 13 is formed on the inner side of the carrying plate 1 , and a slot 14 is formed on the outer side of the carrying plate 1 .

[0033] A screw rod 3 is arranged on the inner side of the bearing plate 1 , and a stabilizing structure is arranged on the outer side of the bearing plate 1 .

[0034] During use, the prefabricated component is first placed on the upper side of the supporting plate 1, and then two motors connected to the screw rod 3 are started at the same time. The motor drives the screw rod 3 to rotate, thereby displacing the threaded groove 11 threadedly connected to the screw rod 3 and displacing the supporting plate 1 on this side, ensuring that both ends of the prefabricated component can contact the upper side of the supporting plate 1, and then all cylinders 22 are started at the same time. The cylinder 22 will push the telescopic rod to displace the clamping plate 23 along the slide groove 13 until the clamping plate 23 is close to the prefabricated component and stops. During the process, the limit rod 25 passes through the square hole on the central end 21 in a parallel position on the other side to maintain the position of the central end 21 without shifting during the displacement process.

[0035] Example 2

[0036] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0037] The stabilizing structure includes a latch 41 plugged into the outside of the bearing plate 1, an L-shaped baffle 42 fixedly connected to the latch 41, and buffer rods 43 evenly arranged on one side of the L-shaped baffle 42. The buffer rods 43 are fixedly connected to the baffle perpendicular to the L-shaped baffle 42 and the bearing plate 1. The number of buffer rods 43 can be increased according to actual needs. A buffer pad 44 is fixedly connected to the buffer rod 43, and the buffer pad 44 is made of a material with a large friction coefficient with the prefabricated component.

[0038] During use, before clamping the prefabricated component, an appropriate number of stabilizing structures can be installed according to the approximate size of the prefabricated component, and the pin 41 can be inserted into the slot 14 on the outside of the load-bearing plate 1 to complete the connection. The subsequent steps of clamping the prefabricated component can be followed. In the process of transporting the prefabricated component, when there are too many impurities at the connection between the prefabricated component and the clamping structure or the prefabricated component shakes too much, resulting in insufficient friction of the clamping structure, the prefabricated component will hit the buffer pad 44 on the inside, and the buffer pad 44 will transfer the impact force to the buffer rod 43, which absorbs the impact force to maintain the stability of the equipment itself, and an appropriate number of stabilizing structures can disperse the impact of the prefabricated component when it shakes, thereby keeping the equipment stable.

[0039] The remaining structures are the same as those of Example 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
