Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a prefabricated component sling. Background Art

[0002] Concrete pipe is a kind of concrete pipe prefabricated in the factory. It has the characteristics of standardized production, high quality and high efficiency. It is widely used in municipal administration, water conservancy, roads and other fields. When the shaft is processed through concrete pipe construction, it is often necessary to vertically lift the concrete pipe and install it vertically.

[0003] At present, it is difficult to implement all the vertical lifting methods of concrete precast pipes. Common methods include lifting the concrete precast pipe horizontally to the installation position and then erecting it; straightening it after tilting it; reserving lifting holes on the concrete precast pipe for easy lifting; when the precast pipe is lifted vertically, the lifting operation is relatively cumbersome, the reserved lifting holes will damage the structure of the precast pipe, and it is more dangerous during lifting.

[0004] For this purpose, a prefabricated component lifting device is proposed. Utility Model Content

[0024] As Figures 1 to 4As shown in the figure, a lifting device for prefabricated components includes a lifting frame 1 and a tubular prefabricated component 9. A hoisting mechanism 2 is fixedly installed at the end of the lifting frame 1, and a vertical frame mechanism 3 is fixedly installed at the end of the hoisting mechanism 2. A movable frame 4 is slidably installed on the surface of the vertical frame mechanism 3. Link rods 5 are hingedly installed on the surfaces of the vertical frame mechanism 3 and the movable frame 4, and a clamping assembly 6 is hingedly installed at the end of the link rod 5. A spring 7 is sleeved on the surface of the vertical frame mechanism 3, and both ends of the spring 7 are fixedly installed with the end face of the vertical frame mechanism 3 and the bottom end of the movable frame 4 respectively. A pull rope 8 is arranged on the top surfaces of the movable frame 4 and the vertical frame mechanism 3. More specifically, when hoisting the tubular prefabricated component 9, the vertical frame mechanism 3 is moved above the tubular prefabricated component 9 through the hoisting mechanism 2. By pulling the pull rope 8, the movable frame 4 is driven to move vertically along the surface of the vertical frame mechanism 3. When the movable frame 4 moves vertically upward, the distance between the clamping assembly 6 and the vertical frame mechanism 3 is reduced through the link rod 5, and the spring 7 is stretched. The clamping assembly 6 is inserted into the interior of the tubular prefabricated component 9. The spring 7 drives the movable frame 4 to move vertically downward, and through the link rod 5, the distance between the clamping assembly 6 and the vertical frame mechanism 3 is increased, so that the surface of the clamping assembly 6 fits with the inner wall of the tubular prefabricated component 9, thereby fixing the tubular prefabricated component 9. The hoisting mechanism 2 can hoist the tubular prefabricated component 9, and can vertically hoist the tubular prefabricated component 9 without damaging the structure of the tubular prefabricated component 9 during hoisting. When hoisting the tubular prefabricated component 9, the spring 7 is in a stretched state. After the tubular prefabricated component 9 is moved to a suitable position by the lifting frame 1 and placed by the hoisting mechanism 2, the pull rope 8 is pulled to drive the movable frame 4 to move vertically, and the link rod 5 drives the clamping assembly 6 to laterally stretch the spring 7, thereby releasing the fixation of the tubular prefabricated component 9.

[0025] The lifting frame 1 includes a U-shaped frame 101. A column 102 is fixedly installed on the top surface of the U-shaped frame 101. A universal wheel 103 is fixedly installed on the bottom surface of the U-shaped frame 101, and the universal wheels 103 are arranged in an array on the bottom surface of the U-shaped frame 101. More specifically, the universal wheels 103 on the bottom surface of the U-shaped frame 101 facilitate the movement of the tubular prefabricated component 9.

[0026] The hoisting mechanism 2 includes a U-shaped seat 201. The U-shaped seat 201 is fixedly installed at the front end of the column 102. A motor 202 is fixedly installed on one side wall of the U-shaped seat 201, and a rotating shaft 203 is fixedly installed at the output end of the motor 202. A winding wheel 204 is fixedly sleeved on the surface of the rotating shaft 203, and a rope 205 is wound around the surface of the winding wheel 204. More specifically, the motor 202 drives the rotating shaft 203 to rotate, and by winding the rope 205 on the surface of the rotating shaft 203, the tubular prefabricated component 9 can be vertically hoisted.

[0027] The vertical frame mechanism 3 includes an upper plate body 301. The bottom end of the rope 205 is fixedly installed with the upper plate body 301, and a notch 302 is formed on the surface of the upper plate body 301. A vertical rod 303 is fixedly installed on the bottom surface of the upper plate body 301, and a lower plate body 304 is fixedly installed on the bottom surface of the vertical rod 303. An activity frame 4 is slidably sleeved on the surface of the vertical rod 303. The surfaces of the activity frame 4 and the lower plate body 304 are hingedly installed with a clamping assembly 6 through a connecting rod 5. A pulling rope 8 is fixedly installed on the top surface of the activity frame 4, and the pulling rope 8 is movably inserted into the upper plate body 301. More specifically, through the vertical rod 303, the vertical movement of the activity frame 4 can be limited and guided. Through the notch 302 on the surface of the upper plate body 301, it is convenient for the operator to take, and it can correspond to the inner wall of the tubular precast member 9.

[0028] The clamping assembly 6 includes a housing 601. The end of the connecting rod 5 is hingedly installed with the housing 601. An installation groove 602 is formed on the inner wall of the housing 601. A rubber sheet 603 is inserted into the interior of the housing 601 and the interior of the installation groove 602. More specifically, through the installation groove 602 formed on the inner wall of the housing 601, it is convenient to install the rubber sheet 603. By contacting the inner wall of the tubular precast member 9 with the rubber sheet 603, it is convenient to fixedly clamp the inner wall of the tubular precast member 9.

[0029] The rubber sheet 603 is made of rubber material, and anti-slip grooves 604 are formed on the surface of the rubber sheet 603. The end face of the rubber sheet 603 is in a fitting setting with the inner wall of the tubular precast member 9. More specifically, through the anti-slip grooves 604 on the surface of the rubber sheet 603, the friction force in contact with the tubular precast member 9 is increased, so as to realize the fixed vertical lifting of the tubular precast member 9.

[0030] In summary: When lifting the tubular prefabricated component 9, the vertical frame mechanism 3 is moved above the tubular prefabricated component 9 by the winch lifting mechanism 2. By pulling the pull rope 8, the movable frame 4 is driven to move vertically along the surface of the vertical frame mechanism 3. As the movable frame 4 moves vertically upward, the distance between the clamping assembly 6 and the vertical frame mechanism 3 is reduced through the connecting rod 5, and the spring 7 is stretched. The clamping assembly 6 is inserted into the interior of the tubular prefabricated component 9. The spring 7 drives the movable frame 4 to move vertically downward, and through the connecting rod 5, the distance between the clamping assembly 6 and the vertical frame mechanism 3 is increased, so that the surface of the clamping assembly 6 fits against the inner wall of the tubular prefabricated component 9, thereby fixing the tubular prefabricated component 9. The winch lifting mechanism 2 enables the tubular prefabricated component 9 to be lifted, and thus enables the vertical lifting of the tubular prefabricated component 9 without damaging the structure of the tubular prefabricated component 9 during lifting. When the tubular prefabricated component 9 is lifted, the spring 7 is in a stretched state. After the tubular prefabricated component 9 is moved to a suitable position by the hanger 1 and then placed by the winch lifting mechanism 2, pulling the pull rope 8 drives the movable frame 4 to move vertically, and the connecting rod 5 drives the clamping assembly 6 to laterally stretch the spring 7, thereby releasing the fixation of the tubular prefabricated component 9.
