Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices for hoisting prefabricated components, in particular to a fast and stable supporting device for hoisting prefabricated concrete components. Background Art

[0002] The support device for lifting prefabricated components is an indispensable tool in prefabricated building construction. It is mainly used for the transportation and installation of prefabricated components to ensure construction efficiency and safety. In modern construction, prefabricated components are used more and more widely. They not only improve construction efficiency, but also help to ensure construction safety. There are many kinds of prefabricated components, the more common ones are concrete components, cement components, road curbs, etc. Support devices are required during the installation process of the components to facilitate better lifting.

[0003] According to the patent number CN118597953A, a support device for lifting prefabricated components with adjustable length has great resistance when the protective component is moved left and right during use, and the bottom and the base plate rub against each other, which not only makes movement difficult but also causes wear and tear, making it impossible to move conveniently. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a fast and stable supporting device for hoisting prefabricated concrete components, which solves the above-mentioned problems.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a fast and stable support device for hoisting prefabricated concrete components, comprising a base plate and a receiving plate fixed to the inner cavity of the base plate, the inner cavity of the base plate is slidably connected to a support plate for supporting the prefabricated component, the inner cavity of the receiving plate is slidably connected to a sliding block through a sliding groove, the bottom of the sliding block is fixedly connected to a return spring, the bottom end of the return spring is fixedly connected to the inner cavity of the base plate, the top of the sliding block is rollingly connected to a ball rollingly connected to the bottom of the support plate, one side of the base plate is slidably connected to a limit rod through a guide groove, and the side of the support plate is provided with a plurality of limit grooves adapted to the limit rod. When in use, according to the prefabricated The position of the support plate is adjusted according to the size of the control component, and the support plate is moved by pulling the handle. The return spring drives the sliding block to rise, and drives the ball to move to the top of the receiving plate to support the support plate. The multi-point ball lifts the support plate, and then the support plate can move smoothly, effectively reducing the friction. After moving into place, the support plate is limited in the horizontal direction by inserting the limit rod into the limit groove at the corresponding position, and then the component is lowered and placed on the support plate. The support plate bears the weight and squeezes the ball downward to drive the sliding block and the ball to retract into the sliding groove. At this time, the support plate falls on the surface of the receiving plate and cannot slide left and right, supporting the prefabricated component. After lifting, the return spring is reset, driving the support plate to rise.

[0006] As a further solution of the present invention: the inner cavity of the base plate is provided with an inner groove adapted to the side protrusion of the support plate. The setting of the inner groove can prevent the support plate from falling off from the inside of the base plate, so that it can only slide back and forth along the base plate.

[0007] As a further solution of the present invention: an opening groove is provided at the left end of the limiting groove. Through the setting of the opening groove, the limiting rod can be smoothly inserted into the limiting groove along the opening groove when inserted.

[0008] As a further solution of the present invention: a handle is fixedly connected to the side of the support plate, and the support plate can be pulled by the handle to move the support plate smoothly.

[0009] As a further solution of the present invention: the width of the limit groove is the same as the width of the limit rod, and the height of the limit groove is the sum of the height of the limit rod and the height of the ball above the receiving plate. When the support plate descends, the limit groove descends, and the top end contacts the top of the limit rod, reserving space for movement.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The utility model lifts up the support plate through multi-point ball bearings, and then the support plate can be moved smoothly at this time, effectively reducing friction. After the movement is in place, the limit rod is inserted into the limit groove at the corresponding position to limit the support plate in the horizontal direction, and then the component is lowered and placed on the support plate. The support plate bears the weight and squeezes the ball bearings downward to drive the sliding block and the ball bearings to retract the sliding groove. At this time, the support plate falls on the surface of the receiving plate and cannot slide left and right, thereby supporting the prefabricated component, making displacement convenient, and can be quickly positioned to prevent left and right movement.

[0012] 2. In the utility model, the support plate bears the weight and squeezes the ball downward to drive the sliding block and the ball back into the sliding groove. At this time, the support plate falls on the surface of the receiving plate and cannot slide left and right, supporting the prefabricated component. After lifting, the reset spring resets and drives the support plate to rise, which can prevent the reset spring from being damaged due to excessive pressure, can be reused, and effectively reduces metal fatigue.
