Description

Technical Field

[0001] This utility model relates to the field of construction hoisting equipment technology, specifically an adjustable universal hoisting equipment for prefabricated components of assembled buildings. Background Technology

[0002] Prefabricated building components are building components that are prefabricated in a factory or on-site and then transported to the construction site for assembly. Their production must follow the design drawings and adopt standardized processes, involving materials such as concrete and steel. The types of components are diverse, such as beams, slabs, columns, walls, and stairs. It can improve construction efficiency, reduce on-site wet work and construction waste. Through precise prefabrication and assembly, the quality and precision of the components can be guaranteed, realizing industrialized building production.

[0003] When assembling prefabricated components for prefabricated buildings, hoisting equipment is needed to transfer and assist in the assembly of the prefabricated building components. Currently, the mainstream hoisting products include special hoisting tools and general hoisting tools. As the name suggests, special hoisting tools are custom-made according to the size of the components, which has poor adaptability and leads to higher construction costs. When adjustable hoisting equipment is used to assemble prefabricated building components, the clamping angle needs to be frequently adjusted according to the size of the components. Although the adjustment connection method is mostly a pin-pin insertion method, the frequent alignment and insertion of the end into the opening anti-detachment pin results in low adjustment efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0023] An adjustable universal lifting device for prefabricated components of assembled buildings includes a scissor hanger 1. A steel beam 2 with a square, hollow structure is horizontally positioned below the scissor hanger 1. Pulling components, each including two pulling rods 4, are horizontally inserted into both sides of the scissor hanger 1. The scissor hanger 1 is connected to the pulling rods 4. Several strip-shaped guide grooves 3 are formed through both sides of the steel beam 2. Several pulling holes 5 are formed through both sides of the pulling rods 4, corresponding to the strip-shaped guide grooves 3. Two control pins 6 are horizontally positioned at the lower end of the scissor hanger 1, and these control pins 6 horizontally move through the strip-shaped guide grooves 3 on both sides of the scissor hanger 1. Two control pins 6 are inserted into one side of the scissor hanger 1, and one of the two pulling core rods 4 is inserted through the pulling hole 5. The pulling hole 5 is located in the strip guide groove 3 away from the scissor hanger 1. When it is necessary to clamp the prefabricated building components, the upper end of the scissor hanger 1 is connected to the lifting rope. At this time, under the pull of the lifting rope and the weight of the steel beam 2 below, the lower scissor feet of the scissor hanger 1 will retract inward. At this time, the scissor hanger 1 can be pulled towards the center of the steel beam 2 by the control pins 6. The control pins 6 can only slide horizontally in the strip guide groove 3. The scissor hanger 1 can be a common scissor hanger in this field, but it must meet the usage requirements of the building weight.

[0024] A clamping assembly is installed to hold the building component. The clamping assembly includes two adjusting connecting sleeves 7, which are movably connected to both sides of the scissor hanger 1. The lower end of the adjusting connecting sleeve 7 is vertically provided with a clamping plate 8. One side of the clamping plate 8 is provided with a triangular reinforcing rib. Anti-slip plates 9 are provided on opposite sides of the two clamping plates 8. When the two clamping plates 8 move towards the center of the steel beam 2 along with the core rod 4, the anti-slip plate 9 on one side of the clamping plate 8 can contact the side of the building component to prevent slippage.

[0025] Each adjusting connecting sleeve 7 is equipped with a pin connection assembly, which includes four welding boxes 10 and four combined pins 12. The four welding boxes 10 are respectively arranged in pairs on both sides of the adjusting connecting sleeve 7. Each welding box 10 has an inner groove 11 on one side, and each inner groove 11 has a through hole penetrating the adjusting connecting sleeve 7. The through hole corresponds to the strip guide groove 3 and the pulling hole 5. One side of each of the four combined pins 12 passes through the through hole and the strip guide groove 3 of the welding box 10 and is inserted into the pulling hole 5 of the pulling core rod 4. The adjusting connecting sleeve 7 is... Two welding boxes 10 on one side are provided with a cover plate 16 by screws. The cover plate 16 covers two inner grooves 11. The cover plate 16 is provided with a guide hole on one side of the inner groove 11. The combined pin 12 moves through the guide hole of the cover plate 16 on the side away from the pulling core rod 4. When the combined pin 12 is inserted into the pulling hole 5 of the pulling core rod 4, the adjusting connecting sleeve 7 moves together with the pulling core rod 4. When the two pulling core rods 4 move towards the center of the steel beam 2, the action of the two hanging plates 8 clamping the building components is completed.

[0026] A spring pressure plate 13 is provided on one side of the combined pin 12 located within the inner groove 11. An insertion spring 14 is sleeved on the side of the combined pin 12 located within the inner groove 11. The two sides of the insertion spring 14 are in contact with the spring pressure plate 13 and the cover plate 16, respectively. A rope groove 15 is provided on the side of the combined pin 12 extending out of the cover plate 16. The cooperation of the combined pin 12, the spring pressure plate 13, and the insertion spring 14 enables the combined pin 12 to automatically and stably insert and pull the core rod 4. When adjusting the distance between the two hanging plates 8 inside the hole 5, pull the combined pin 12 to extend one end of the cover plate 16. After the combined pin 12 disengages from the pulling hole 5 and the strip guide groove 3, it can be automatically inserted at the next pulling hole 5 and strip guide groove 3 position, realizing quick docking of the adjustment. The rope groove 15 is set so that the two combined pins 12 on the same side can be pulled at the same time by tying a pull rope in the rope groove 15, which facilitates the combined pin 12 to disengage from the strip guide groove 3 and the pulling hole 5.

[0027] In addition, the detachable design of the cover plate 16 makes it easy to replace the combination pin 12 and the insertion spring 14 for maintenance, making the operation simple and worry-free.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
