Description

Technical Field

[0001] The utility model relates to the technical field of sandwich panel lifting clamps, and more specifically, the utility model relates to an installation lifting clamp for sandwich panels that prevents punching. Background Technique

[0002] The sandwich panel is a common product in current building materials. It can not only have good flame retardancy and sound insulation but also be environmentally friendly and efficient. When installing the sandwich panel at a high place, a lifting device is required to lift the sandwich panel to a high place for installation.

[0003] However, when the current sandwich panel is hoisted, it is necessary to punch holes at the edge of the sandwich panel, and a self-made hook directly penetrates the panel surface for hoisting, which causes certain strength and appearance damage to the sandwich panel.

[0004] After retrieval, the Chinese patent with the authorization announcement number CN219652505U discloses a sandwich panel lifting clamp. In the clamping process of this structure with the sandwich panel body, the original process of punching holes at the edge of the sandwich panel body is reduced, the hoisting efficiency is improved, and the strength of the sandwich panel body itself is not reduced, making the handling process stable and reliable, and also making the appearance of the sandwich panel body more beautiful.

[0005] However, when this structure is actually used, this structure drives the jacking screw to rotate through the adjusting handwheel belonging to the jacking screw to realize the clamping operation of the sandwich panel. However, there is a lack of a structure for limiting the adjusting handwheel, resulting in the risk that the adjusting handwheel rotates due to accidental contact during hoisting and installation, and then the sandwich panel falls. In view of this, the utility model proposes an installation lifting clamp for sandwich panels that prevents punching. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides an installation lifting clamp for sandwich panels that prevents punching to solve the problems raised in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: an installation lifting clamp for sandwich panels that prevents punching, including a concave frame, a lifting ear is fixedly arranged at the top of the concave frame, an adjusting screw rod is rotatably arranged on the outer wall of the concave frame, a convex clamping plate is arranged inside the concave frame, a universal joint is arranged between the adjusting screw rod and the convex clamping block, a turntable is arranged at one end of the adjusting screw rod, and a locking structure is arranged on the surface of the turntable.

[0008] In order to be able to clamp sandwich panels with different thicknesses, preferably, the adjusting screw rod is threadedly connected to the outer wall of the concave frame, the turntable is fixedly connected to one end of the adjusting screw rod, and the other end of the adjusting screw rod is connected to the convex clamping plate through a universal joint.

[0009] In order to improve the anti-slip effect of the lifting clamp, preferably, two first serrated anti-slip pads are fixedly arranged on the inner wall of the convex clamping plate, and a second serrated anti-slip pad is fixedly installed on the inner wall of the concave frame.

[0010] In order to avoid the risk that the turntable rotates due to collision during hoisting, resulting in the dropping of the sandwich panel, preferably, the locking structure includes a sleeve, the sleeve is fixedly installed on the outer wall of the concave frame and is located at the bottom of the turntable. An L-shaped pull rod is arranged inside the sleeve. One end of the L-shaped pull rod is provided with a chuck. A plurality of equally spaced limit holes are distributed in a ring on the surface of the turntable. A limit post is fixedly installed on the surface of the chuck. The limit post is adapted to the structure of the limit hole. One end of the L-shaped pull rod is slidably connected inside the sleeve. A slider is fixedly installed at one end of the L-shaped pull rod inside the sleeve. One end of the slider is provided with a tension spring. Both ends of the tension spring are fixedly connected to the inner wall of the sleeve and one end of the slider respectively.

[0011] The technical effects and advantages of the present utility model:

[0012] 1. By placing the concave frame outside the sandwich panel, the turntable drives the adjusting screw rod to rotate, and drives the convex clamping plate to extend towards the outer wall of the sandwich panel, adapting to sandwich panels of different thicknesses for clamping and installation, so that the sandwich panel is clamped between the convex clamping plate and the concave frame. Moreover, the first serrated anti-slip pad and the second serrated anti-slip pad not only prevent scratches on the sandwich panel, but also improve the anti-slip effect. The entire sandwich panel can be hoisted through the lifting lug on the concave frame. Overall, there is no need for destructive punching hoisting operation on the surface of the sandwich panel, and the entire lifting clamp can be recycled, improving the use effect;

[0013] 2. By setting the locking structure, pulling the L-shaped pull rod to one side causes the L-shaped pull rod to drive the slider to slide inside the sleeve, and stretch the tension spring. The limit post at the chuck at the top of the L-shaped pull rod is inserted into the limit hole on the surface of the turntable. After the tension spring is stretched, it returns to its original position, thereby limiting the turntable, avoiding the risk that the sandwich panel accidentally touches the turntable due to the shaking during hoisting, and further improving the safety of the sandwich panel during hoisting.
