Description

Technical Field

[0001] This utility model relates to the field of hoisting component technology, specifically a hoisting component for the production and processing of PC prefabricated components. Background Technology

[0002] Background Technology: Precast PC components refer to concrete products manufactured in factories using standardized methods. They require on-site model making, pouring, and curing. Precast components are commonly used in large-scale construction and transportation projects, playing a vital role in these fields. The quality of precast PC components can generally be better controlled through mechanized production. Compared with traditional on-site molding, factory molds can be reused, saving costs. During the production and processing of precast PC components, hoisting equipment is needed to lift them to designated locations.

[0003] Chinese utility model patent application CN115303930A discloses a hoisting assembly for the production and processing of precast PC components, including a hoisting frame. A hoisting component is connected to the top of the hoisting frame, and reels are rotatably connected to both ends of the hoisting frame. A limiting head is provided at the top of the hoisting frame, aligned with the position of the reels, and is inserted into the top of the hoisting frame and locked onto the reels. A chain is connected to the bottom of the reels, and a hook is provided at the bottom of the chain. This invention solves the problem that existing hoisting assemblies cannot adjust the chain, resulting in the inability to quickly adjust the chain length at different positions according to usage requirements during hoisting. By improving and optimizing the structure of the hoisting assembly, the chain of the hoisting assembly can be adjusted according to usage requirements. This structure of the hoisting assembly is flexible in use, easy to operate, and convenient for quickly lifting precast components in conjunction with hoisting equipment. However, this device does not solve the problems of easily adjusting the angle and height, or improving the stability of hoisting precast PC components. Therefore, we propose a hoisting assembly for the production and processing of precast PC components. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting assembly for the production and processing of PC precast components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hoisting assembly for the production and processing of precast PC components includes a fixed base, a main body mechanism movably disposed on the top of the fixed base, a control mechanism fixedly disposed on the top of the main body mechanism, and a support mechanism fixedly disposed on the bottom of the fixed base. The main body mechanism includes a support shaft, a device mounting shell, and a fixed column. The support shaft is movably disposed inside the fixed base, the device mounting shell is movably disposed on the top of the support shaft, and the fixed column is fixedly disposed on the top of the device mounting shell.

[0007] Preferably, a drive motor is fixedly installed at the bottom of the support shaft. The support shaft adjusts the angle of the device mounting shell by means of the rotation of the drive motor, which is beneficial to better adjust the angle of the structure at the top of the device mounting shell by means of the drive motor and the support shaft.

[0008] Preferably, a hydraulic cylinder is fixedly installed inside the fixed column, and an L-shaped support column is movably installed on the top of the hydraulic cylinder. An insertion hole is opened at the bottom of one side of the L-shaped support column, and a fixed rotating shaft is movably installed inside the L-shaped support column. A rotating support column is fixedly installed in the middle of the fixed rotating shaft, and a fixed ring is fixedly installed at the top of the fixed rotating shaft. A T-shaped connecting rod is fixedly installed at the bottom of the fixed ring, and a first set of collars is fixedly installed at the bottom of the T-shaped connecting rod. When adjusting the hoisting angle, the PC precast component panels often fall off due to shaking. Therefore, when the rotating support column shakes violently, the rotating support column will swing freely at the top of the fixed rotating shaft with inertia, thereby adapting to the inertia caused by the violent shaking and preventing the PC precast component panels from falling off.

[0009] Preferably, a plurality of high-strength ropes are movably arranged inside the first set of collars, and a second set of collars is movably arranged on the high-strength ropes at the other end away from the first set of collars. A square support frame is fixedly arranged at the bottom end of the second set of collars. A first set of electric push rods is fixedly arranged inside the square support frame, and a second set of electric push rods is fixedly arranged on the other side away from the first set of electric push rods. U-shaped clamping plates are movably arranged on both sides of the first set of electric push rods and the second set of electric push rods. The first set of electric push rods and the second set of electric push rods drive the U-shaped clamping plates to move and clamp towards the center, so that the PC precast component plate is clamped in the middle of the square support frame and the U-shaped clamping plates.

[0010] Preferably, the control mechanism includes a controller and a control screen. The control screen is fixedly mounted on the surface of the controller, and a group of control buttons is fixedly mounted on one side of the control screen. Both the control screen and the control button group are electrically mounted on the surface of the controller, which facilitates better control of Q through the control mechanism.

[0011] Preferably, the support mechanism includes a device mounting plate and a first set of bolt holes. The first set of bolt holes is fixedly provided on the surface of the device mounting plate, and a second set of bolt holes is fixedly provided on one side of the first set of bolt holes. This facilitates the installation of the processing hoisting component on other equipment through the support mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This is a hoisting assembly for the production and processing of precast PC components. The assembly places the precast PC component on a horizontal surface. A hydraulic cylinder lowers an L-shaped support column from the top of a fixed column, causing a square support frame to rest on top of the PC component. A first and second set of electric push rods move a U-shaped clamping plate towards the center, clamping the PC component between the square support frame and the U-shaped clamping plate. After the placement is determined, a hydraulic cylinder drives the structure at the bottom of the L-shaped support column to rise and fall freely. A drive motor and support shaft rotate the structure at the top of the mounting shell. When adjusting the hoisting angle, the PC component often falls due to swaying. Therefore, when the rotating support column sways violently, the top of the fixed shaft sways slightly due to inertia, thus mitigating the inertia and preventing the PC component from falling. This design allows for easy adjustment of the angle and height of the hoisting assembly and improves the stability of hoisting the PC component.

[0014] This hoisting assembly for the production and processing of precast PC components achieves easy control and installation on other equipment through a combination design of control and support mechanisms. Attached Figure Description

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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution for a hoisting assembly used in the production and processing of precast PC components:

[0022] A hoisting assembly for the production and processing of precast PC components includes a fixed base 1, a main body mechanism movably mounted on the top of the fixed base, a control mechanism fixedly mounted on the top of the main body mechanism, and a support mechanism fixedly mounted on the bottom of the fixed base 1. The main body mechanism includes a support shaft 2, a device mounting shell 3, and a fixed column 4. The support shaft 2 is movably mounted inside the fixed base 1, the device mounting shell 3 is movably mounted on the top of the support shaft 2, and the fixed column 4 is fixedly mounted on the top of the device mounting shell 3.

[0023] In this embodiment, preferably, a drive motor 5 is fixedly installed at the bottom of the support shaft 2. The support shaft 2 adjusts the angle of the device mounting shell 3 by means of the rotation of the drive motor 5, which is beneficial to better adjust the angle of the structure at the top of the device mounting shell 3 by means of the drive motor 5 and the support shaft 2.

[0024] In this embodiment, preferably, a hydraulic cylinder 6 is fixedly installed inside the fixed column 4, and an L-shaped support column 7 is movably installed on the top of the hydraulic cylinder 6. An insertion hole 8 is opened at the bottom of one side of the L-shaped support column 7. A fixed rotating shaft 9 is movably installed inside the L-shaped support column 7. A rotating support column 10 is fixedly installed in the middle of the fixed rotating shaft 9. A fixed ring 11 is fixedly installed on the top of the fixed rotating shaft 9. A T-shaped connecting rod 12 is fixedly installed at the bottom of the fixed ring 11. A first set of collars 13 is fixedly installed at the bottom of the T-shaped connecting rod 12. When adjusting the hoisting angle, the PC precast component panels often fall off due to shaking. Therefore, when the rotating support column 10 shakes violently, the rotating support column 10 will shake freely at the top of the fixed rotating shaft 9 with inertia, thereby adapting to the inertia caused by the violent shaking and preventing the PC precast component panels from falling off.

[0025] In this embodiment, preferably, a plurality of high-strength ropes 14 are movably arranged inside the first set of collars 13, and a second set of collars 15 is movably arranged on the high-strength ropes 14 away from the other end of the first set of collars 13. A square support frame 16 is fixedly arranged at the bottom end of the second set of collars 15. A first set of electric push rods 17 is fixedly arranged inside the square support frame 16, and a second set of electric push rods 18 is fixedly arranged on the other side away from the first set of electric push rods 17. U-shaped clamping plates 19 are movably arranged on both sides of the first set of electric push rods 17 and the second set of electric push rods 18. The first set of electric push rods 17 and the second set of electric push rods 18 drive the U-shaped clamping plates 19 to move and clamp towards the center, so that the PC precast component plate is clamped in the middle of the square support frame 16 and the U-shaped clamping plates 19.

[0026] In this embodiment, preferably, the control mechanism includes a controller 20 and a control screen 21. The control screen 21 is fixedly mounted on the surface of the controller 20, and a control button group 22 is fixedly mounted on one side of the control screen 21. Both the control screen 21 and the control button group 22 are electrically mounted on the surface of the controller 20, which facilitates better control of Q through the control mechanism.

[0027] In this embodiment, preferably, the support mechanism includes a device mounting plate 23 and a first set of bolt holes 24. The first set of bolt holes 24 is fixedly provided on the surface of the device mounting plate 23, and a second set of bolt holes 25 is fixedly provided on one side of the first set of bolt holes 24. This facilitates the installation of the processing hoisting component on other equipment through the support mechanism.

[0028] In this embodiment, a hoisting assembly for the production and processing of precast PC components is used as follows: Bolts are installed at the top of the first set of bolt holes 24 and the second set of bolt holes 25 to transport the component (Q) to its destination. The control screen 21 and control button group 22 are used to open the assembly, placing the precast PC component on a horizontal surface. The hydraulic cylinder 6 drives the L-shaped support column 7 to descend from the top of the fixed column 4, causing the square support frame 16 to rest on top of the precast PC component. The first set of electric push rods 17 and the second set of electric push rods 18 drive the U-shaped clamping plate 19 to move towards the center to clamp the precast PC component. The sheet material is clamped in the middle of the square support frame 16 and the U-shaped clamping plate 19. After the placement position is determined, the structure at the bottom of the L-shaped support column 7 is freely raised and lowered by the hydraulic cylinder 6. The structure at the top of the device mounting shell 3 is rotated by the drive motor 5 and the support shaft 2. When adjusting the hoisting angle, the clamped PC precast component sheet material often falls off due to shaking. Therefore, when the rotating support column 10 shakes violently, the rotating support column 10 will shake slightly with inertia at the top of the fixed shaft 9, thereby adapting to the inertia brought by the violent shaking and preventing the PC precast component sheet material from falling off.
