Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped PC component construction, in particular to special-shaped PC component hoisting equipment. Background Art

[0002] During the hoisting, docking, and installation of special-shaped PC components, when they are hoisted near the preset installation location of the building, since the special-shaped PC components are located outside the building, in order to ensure that the special-shaped PC components can be accurately installed in the preset location, it is necessary to manually attach to the outside of the building to pull the special-shaped PC components or use slings to adjust the state and position of the special-shaped PC components. Relying on the cooperation of multiple workers, the special-shaped PC components are stabilized in the adjusted state and position, and finally lowered to the preset position to complete the docking and installation of the special-shaped PC components. Since the special-shaped PC components are located outside the building, manual operation is required outside the building, resulting in certain safety hazards in high-altitude operations. At the same time, the shaking of the special-shaped PC components will also pull workers, affecting their stability while standing on the building. In addition, the special-shaped PC components, after the state and position are adjusted, rely on manual support for positioning, which has poor stability. Once they deviate, they must be repeatedly adjusted and re-calibrated, affecting the construction progress. Utility Model Content

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, a device for lifting special-shaped PC components includes a suspension rod 1, with hooks 2 installed on both sides of the outer side of the suspension rod 1, a pull rod 3 provided at the front end of the suspension rod 1, a support seat 4 provided at the bottom end of the pull rod 3, and a stop rod 5 extending vertically downward provided at the end of the suspension rod 1 away from the pull rod 3. The pull rod 3 can be extended and retracted in the height direction, and a quick-connect hole is provided on the support seat 4. During the process of lifting the special-shaped PC component to the preset position and docking the special-shaped PC component, the staff stands on the building, pulls the pull rod 3 toward one side of the building, and then uses the quick-connect hole to fix the support seat 4 to the building. At this time, the pull rod 3 and the suspension rod 1 can form a certain limit on the special-shaped PC component, preventing the special-shaped PC component from shaking at high altitude, thereby improving safety. Then, the pull rod 3 and the suspension rod 1 can be used to pull the special-shaped PC component toward the side of the building to adjust the distance between the special-shaped PC component and the building. By utilizing the performance of the pull rod 3 being able to extend and retract in the height direction, the special-shaped PC component can be directly lowered by a crane, so that the special-shaped PC component can fall into the position to be installed more accurately.

[0024] By making the above arrangement, when realizing the hoisting operation of the special-shaped PC component, the worker does not need to stand on the building and lean outward to pull the sling, which is safer. At the same time, the use of the pull rod 3, the suspension rod 1 and the support base 4 to limit the special-shaped PC component can better stabilize the state and position of the special-shaped PC component, make it more convenient to accurately lower and dock the special-shaped PC component, and reduce the construction difficulty of high-altitude operations.

[0025] In this embodiment, the quick-connect hole is a through hole, and a hole can be drilled on the building to install a bolt, or a steel wire or iron wire can be passed through the quick-connect hole to tie and fix the support base 4 to the building or the steel bars of the building. This is the existing technology and will not be described in detail here.

[0026] An adjustment slot 6 is provided at one end of the boom 1 facing the draw rod 3. An adjustment rod 7 is rotatably mounted on the top end of the draw rod 3 facing one side of the boom 1, which cooperates with the adjustment slot 6 to control the displacement of the draw rod 3 along the length direction of the boom 1. The adjustment rod 7 is rotatably connected to the draw rod 3. By rotating the adjustment rod 7 to move within the adjustment slot 6, the draw rod 3 is driven to move. By precisely controlling the position of the draw rod 3, the position of the special-shaped PC component in the front-to-back direction is adjusted to achieve the distance between the special-shaped PC component and the building according to the preset installation position, ensuring that the special-shaped PC component can enter the preset installation position more accurately and directly, thereby improving the construction efficiency of the hoisting operation, docking and installation of the special-shaped PC component.

[0027] The adjustment rod 7, extending from one side of the boom 1 toward the side of the pull rod 3, comprises a first rod portion 7.1 and a second rod portion 7.2. The first rod portion 7.1 is a threaded rod, while the second rod portion 7.2 is a smooth rod-shaped structure. The adjustment slot 6 comprises a first slot body 6.1, a second slot body 6.2, and a third slot body 6.3. The second slot body 6.2 is located between the first and third slot bodies 6.1 and 6.3. The first and third slot bodies 6.1 and 6.3 are configured as threaded grooves capable of threading with the first rod portion 7.1. The second slot body 6.2 has a smooth inner wall. In the initial state, the first rod portion and the first slot body 6.1 are threadedly engaged. At this time, the pull rod 3 and the boom 1 are relatively short. In this state, the pull rod 3 rests on one side of the special-shaped PC component, improving the stability of the special-shaped PC component during lifting. When the special-shaped PC component is hoisted to a predetermined location, the first rod portion 7.1 is separated from the first groove 6.1 by rotating the adjustment rod 7. Then, the pull-out rod 3 can be quickly pulled outward to thread the first rod portion 7.1 into the third groove 6.3. The distance between the special-shaped PC component and the building can be adjusted by rotating the adjustment rod 7, using the support base 4 and the pull-out rod 3 as the fulcrum.

[0028] The top of the pulling rod 3 is fixedly mounted with a top plate 8 that slides on the upper surface of the boom 1. The top plate 8 allows the pulling rod 3 to remain stable during displacement to prevent it from deviating from the predetermined trajectory. At the same time, the sliding connection between the top plate 8 and the boom 1 also allows the pulling rod 3 to move freely within a certain range.

[0029] The pull rod 3 comprises an upper rod body 3.1 and a lower rod body 3.2. The bottom end of the upper rod body 3.1 is plugged into the top end of the lower rod body 3.2, and the adjustment rod 7 is rotatably mounted on the upper rod body 3.1. The upper rod body 3.1 is raised and lowered on the lower rod body 3.2 to accommodate the position of the special-shaped PC component after calibration.

[0030] The top of the support base 4 is provided with a chute 9 extending perpendicularly to the displacement direction of the pull rod 3. The bottom end of the pull rod 3 slides in the chute 9, and a transverse adjustment member is connected between one of the pull rods 3 and the support base 4 at its bottom. The pull rod 3 can slide horizontally on the support base 4. The transverse adjustment member is used to adjust the horizontal position of the pull rod 3 on the support base 4, and is used to adjust the left-right position of the special-shaped PC component. This makes it easier to align the special-shaped PC component with the preset installation position on the building, further improving the construction efficiency of the hoisting and docking of the special-shaped PC component.

[0031] The transverse adjustment member includes a threaded through groove 10 provided at the bottom end of the pulling rod 3 and a transverse bolt 11 rotatably mounted on the support seat 4 , and the transverse bolt 11 is threadably engaged with the threaded through groove 10 .

[0032] Positioning plates 12 are fixedly mounted on the side of the pull rod 3 and support base 4 facing away from the boom 1. Positioning bolts 13 are connected between the two positioning plates 12, one above the other. By inserting the positioning bolts 13 through the positioning plates 12 on the pull rod 3 and support base 4, the pull rod 3 and support base 4 can be positioned horizontally. Before operating the lateral adjustment member, first remove the positioning bolts 13 and then rotate the transverse bolts 11.

[0033] A hook seat 14 is fixedly mounted on the top of the hook 2, and a slide plate 15 is provided on the outside of the boom 1. The design of the hook seat 14 and the slide plate 15 allows the hook 2 to slide on the outside of the boom 1 to accommodate special-shaped PC components of different widths or shapes, thereby enhancing the flexibility and adaptability of the equipment.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
