Description

Technical Field

[0001] The embodiments of this utility model belong to the technical field of modular building hoisting equipment, and more specifically, relate to a modular building component hoisting device that is easy to adjust the hoisting points. Background Technology

[0002] With the rapid development of prefabricated buildings, modular buildings have gradually become one of the mainstream construction methods. Unlike traditional prefabricated buildings that separate beams, slabs, and columns into independent prefabricated components, modular building components can complete the installation of the main building structure, internal water, electricity, and some equipment in the factory. During construction, multiple modular building components only need to be assembled together.

[0003] Due to the high integration of modular building components and their relatively complex shapes, the arrangement of lifting points has become more diverse, placing higher demands on the lifting equipment. Currently, the lifting equipment used on site is generally a rectangular frame structure, with lifting points set at the lower part of the four corners of the frame structure. When the position of the lifting points needs to be adjusted, new lifting lugs generally need to be welded on. The lifting points of the lifting equipment cannot quickly adapt to the pre-embedded lifting ring positions of the modular building components, making the operation more complicated. At the same time, it is difficult to accurately set the position of the lifting points.

[0004] Therefore, there is an urgent need for a modular building component hoisting device that can adjust the hoisting points according to the pre-embedded hoisting ring positions of the modular building components, and is simple to operate and easy to construct. Summary of the Invention

[0005] To address the problems of existing hoisting devices, such as the difficulty in quickly adapting the lifting points to the pre-embedded lifting ring positions of modular building components, the complexity of operation, and the difficulty in accurately setting the lifting point positions, this utility model provides a modular building component hoisting device that is easy to adjust the lifting points to solve these problems.

[0006] To achieve the above objectives, this utility model provides a modular building component hoisting device that is easy to adjust the lifting points. It includes a frame connected to the main hook at the top by a steel wire rope. The frame is a lattice structure, comprising multiple sets of vertically intersecting horizontal and vertical beams. A first chute located at the bottom of the frame has multiple sets, each fixed to the bottom of the horizontal and vertical beams. The chute bottom has a first opening along its central axis, and racks are provided on the bottom of the chute on both sides of the first opening. A slider located in the first chute is a T-shaped steel component, comprising a horizontal plate and a vertical plate perpendicular to the central axis at the bottom of the horizontal plate. The bottom of the horizontal plate also has locking teeth located on both sides of the vertical plate, which are adapted to the racks and interlock. The vertical plate has hoisting holes for connecting a hand-operated hoist.

[0007] Furthermore, the first groove is used to limit the sliding block, and it is made of channel steel. The top groove is fixed to the bottom of the crossbeam and the longitudinal beam by welding.

[0008] Furthermore, the thickness of the vertical plate is the same as the width of the first opening, allowing the vertical plate to undergo linear displacement along the first opening.

[0009] Furthermore, it also includes a reset assembly, which includes a second slide, a spring rod, and a slide plate.

[0010] Furthermore, the second slide groove is located inside the first slide groove, and its top opening is fixed to the bottom of the crossbeam and the longitudinal beam respectively by welding; the bottom of the second slide groove has a second opening along the central axis; the slide plate is slidably disposed in the second slide groove, and its diameter is greater than the width of the second opening; the bottom of the spring rod is fixedly connected to the bottom of the slide plate, and its bottom passes through the second opening and is fixedly connected to the top of the slider, and its elastic potential energy is greater than the weight of the slider itself.

[0011] Furthermore, both the crossbeams and longitudinal beams are made of square steel.

[0012] Furthermore, the top of the hanger is fixedly provided with multiple sets of lifting lugs, which are used as lifting points to connect the wire rope to the hanger.

[0013] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0014] (1) The hoisting device of this utility model is easy to operate. The position of the hoisting point can be quickly adjusted according to the position of the pre-embedded hoisting ring of the modular building component.

[0015] (2) The hoisting device of this utility model can accurately adjust the position of the hoisting point.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1-4 As shown, this utility model provides a modular building component hoisting device that is easy to adjust the hoisting point, including a main hook 1, a wire rope 2, a hanger 3, a lifting lug 4, a first slide groove 6, a slider 8, and a hand-operated hoist 14. The upper end of the main hook 1 is connected to the lifting equipment; the wire rope 2 is provided in multiple sets, with the upper ends of the multiple sets of wire rope 2 suspended on the main hook 1 and the lower ends respectively connected to the corresponding lifting lugs 4 provided on the top of the hanger 3; the hanger 3 is a grid frame structure, including multiple sets of vertically intersecting horizontal beams and longitudinal beams; the first chute 6 is a through groove, which is provided in multiple sets and respectively fixed to the bottom of the horizontal beams and longitudinal beams. The bottom of the chute 6 has a first opening along the central axis, and the bottom of the groove on both sides of the first opening is provided with racks 12; the slider 8 is a T-shaped steel component, including a horizontal plate and a vertical plate vertically provided at the bottom central axis of the horizontal plate. The bottom of the horizontal plate is also provided with teeth 11, which are located on both sides of the vertical plate and are adapted to the racks 12; the vertical plate has a lifting hole 13 for connecting a hand chain hoist 14. During the installation and adjustment of the hoisting device of this utility model, the hoisting equipment moves the lifting frame 3 above the modular building component 5, and moves the slider 8 along the first opening, so that the slider 8 slides directly above the lifting lug 4. A hand-operated hoist 14 connects the slider and the lifting ring 15. The hand-operated hoist 14 is slightly tightened, so that the lower part of the slider 8 is tightened and moves downward, so that the locking teeth 11 and the rack 12 engage, temporarily fixing the slider 8. After completion, the construction personnel leave, and the hoisting equipment moves the modular building component 5 to the installation position for the next construction operation. The hoisting device of this utility model can adapt to the arrangement of lifting points of various modular building components by sliding adjustment of the lifting points. It is simple to operate and highly practical.

[0024] like Figure 1-2 As shown, the main hook 1 is used to connect with the lifting equipment, which has a large lifting weight. By suspending multiple sets of steel wire ropes 2 on the main hook 1, the modular building components 5 are lifted and moved smoothly.

[0025] Multiple sets of lifting lugs 4 are fixedly installed on the top of the gantry 3 to serve as lifting points for connecting the wire rope 2 to the gantry 3. When using the wire rope 2 to connect the lifting lugs 4, the appropriate lifting lugs 4 can be selected to connect the wire rope 2 according to the position of the lifting ring 15 on the top of the modular building component 5, so that the center of gravity of the modular building component 5 is located below the center of the gantry 3, thereby ensuring the smooth progress of the hoisting operation.

[0026] The lifting frame 3 is a lattice frame structure, including multiple sets of vertically intersecting horizontal beams and vertical beams; the horizontal beams and vertical beams are all made of square steel. Due to the hollow structure of the square steel tube, the weight is significantly reduced, and it has high compressive, bending and torsional strength, and can withstand large loads. While ensuring structural strength, it can effectively reduce the overall lifting weight and ensure the safety and stability of the lifting operation.

[0027] like Figure 2-4 As shown, the first chute 6 is used to limit the sliding slider 8, thereby changing the position of the lifting point. It is a channel steel, and the top opening of the channel is fixed to the bottom of the crossbeam and the longitudinal beam by welding. Furthermore, the first chute 6, which is respectively located at the bottom of the crossbeam and the longitudinal beam, has its groove wall cut off at the intersection to form a cross through groove, so that the slider 8 can slide smoothly in a straight line along the first opening. The bottom of the first chute 6 has a first opening along the central axis. The width of the first opening is adapted to the thickness of the lower end of the slider 8, so that the slider 8 can move in a straight line along the first opening. Furthermore, the bottom of the first chute 6 has a rack 12, which is located on both sides of the first opening. By interlocking with the locking teeth 11 on the slider 8, it can prevent the slider 8 from sliding in the first chute 6 during the lifting operation under the heavy clamping force of the modular building component 5, thus ensuring the stability of the lifting operation.

[0028] like Figure 3-4 As shown, the slider 8 is a T-shaped steel component, including a horizontal plate and a vertical plate vertically disposed at the bottom center axis of the horizontal plate; wherein, the bottom of the horizontal plate is also provided with a locking tooth 11, which is located on both sides of the vertical plate and is adapted to the rack 12; the thickness of the vertical plate is the same as the width of the first opening, so that the vertical plate can be linearly displaced along the first opening; furthermore, the lower end of the vertical plate is provided with a lifting hole 13, which is located at the bottom of the first sliding groove 6 and is used to hang the hand chain hoist 14.

[0029] The hoisting device of this utility model also includes a reset component. After the operator releases the hand chain hoist 14, the slider 8 is no longer subjected to the lower pulling force. At this time, under the pull of the elastic rod 9, the slider 8 overcomes its own weight, and the meshing teeth 11 and the rack 12 will automatically separate. The operator can then push the slider 8 horizontally to move the hoisting point to the designated position, which can greatly improve the hoisting efficiency. The reset assembly includes a second slide groove 7, a spring rod 9, and a slide plate 10. The second slide groove 7 is located inside the first slide groove 6, and its top opening is fixed to the bottom of the crossbeam and the longitudinal beam by welding. The bottom of the second slide groove 7 has a second opening along the central axis. The slide plate 10 is slidably disposed inside the second slide groove 7, and its diameter is larger than the width of the second opening. The bottom of the spring rod 9 is fixedly connected to the bottom of the slide plate 10, and its bottom passes through the second opening and is fixedly connected to the top of the slider 8. Its elastic potential energy is greater than the weight of the slider 8 and the hand chain hoist 14. When the slider 8 is not under external load, it lifts the slider 8 by its own elastic potential energy, causing the interlocking teeth 11 and the rack 12 to separate.

[0030] When the hoisting device of this utility model is in operation, according to the position of the top lifting ring 15 of the modular building component 5, the corresponding lifting lug 4 is selected to connect the wire rope 2, so that the center of gravity of the modular building component 5 is located below the center of the hanger 3; after the wire rope 2 is connected to the lifting lug 4, the hoisting equipment moves the hanger 3 above the modular building component 5. Since the slider 8 has no external load, the spring rod 9 pulls the slider 8 up to the reset state, and the interlocking teeth 11 and rack 12 separate. The operator can pull the hand chain hoist 14, thereby driving the slider 8 to slide directly above the lifting lug 4, and connect the lower end of the hand chain hoist 14 to the lifting lug 4; After multiple chain hoists 14 are connected to the lifting lugs 4 of the modular building component 5, the operator stands up, and the lifting equipment lifts the modular building component 5. At this time, the external load on the slider 8 is much greater than the potential energy of the spring rod 9, and the slider 8 descends, so that the locking teeth 11 and the rack 12 are tightly engaged, preventing the slider 8 from sliding in the first slide groove 6 during the lifting operation, thus ensuring the stability of the lifting operation. After the lifting equipment turns the modular building component 5 to the installation position, the connection between the chain hoist 14 and the lifting lugs 4 of the modular building component 5 is removed, and the spring rod 9 pulls up the slider 8 to reset and unlock it, so that the next round of lifting point adjustment and lifting operation can be carried out.

[0031] The hoisting device of this utility model is simple to operate. The position of the hoisting point can be quickly adjusted according to the position of the pre-embedded hoisting ring of the modular building component. There is no need to re-weld new hoisting lugs, which simplifies the operation process and facilitates construction.

[0032] The hoisting device of this invention allows for precise adjustment of the hoisting point position. Through the cooperation of structures such as sliding grooves, sliders, and racks, the hoisting point position can be accurately set, thereby improving the accuracy and reliability of hoisting.

[0033] The hoisting device of this utility model has strong applicability. It can adapt to modular building components of different shapes and sizes, and has good versatility and flexibility, which can meet diverse hoisting needs.

[0034] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
