Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to multi-functional hoisting tools. Background Technology

[0002] With the continuous development of construction technology, prefabricated buildings are becoming increasingly common. Unlike traditional construction methods, prefabricated buildings transfer a large amount of on-site work to factories. Prefabricated components and accessories are manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Some prefabricated components and accessories need to be hoisted to heights for installation. Damage to prefabricated components during storage, transportation, and hoisting is difficult to repair, causing delays and economic losses. Existing prefabricated component hoisting frames are usually fixed structures adapted to the prefabricated component structure to ensure stability during hoisting. Using multiple hoisting frames to hoist each prefabricated component and accessory separately will inevitably increase hoisting costs. Utility Model Content

[0003] The present invention aims to solve the problem that the above-mentioned prefabricated component lifting frame is not suitable for lifting a variety of prefabricated components and accessories, and thus provides a lifting tool that can be used for lifting a variety of prefabricated components or accessories.

[0004] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0005] A multi-functional lifting tool includes a fixed frame with multiple sliding rods slidably mounted on it. Each sliding rod has a first fastener connected to both ends, which is used to engage with the fixed frame. Each sliding rod has multiple second fasteners slidably mounted on it, and each second fastener is connected to a support rod. Lifting lugs for connecting a lifting mechanism are fixed to both ends of the fixed frame.

[0006] Compared with the prior art, the advantages of this utility model, which adopts the above technical solution, are as follows:

[0007] This utility model discloses a multi-functional hoisting tool. A fixed frame serves as the hoisting base, and lifting lugs on both sides are used to connect the hoisting mechanism for easy lifting. Multiple support rods serve as limiting elements for prefabricated parts or accessories on the fixed frame to prevent them from falling during hoisting. The support rods are slidably mounted on a sliding rod via a second fastener, and the sliding rod is slidably mounted on the fixed frame, making it easy to adjust the position of each support rod so that it can be used to clamp and place different prefabricated parts or accessories.

[0008] As a preferred embodiment, a further technical solution of this utility model is:

[0009] The mounting frame includes a rectangular frame at the bottom and lifting brackets fixed to the front and rear ends of the rectangular frame. Lifting lugs are fixed to the top of the lifting brackets. The rectangular frame serves as the base for fixing the lifting brackets, facilitating the lifting of the mounting brackets via the lifting lugs.

[0010] The rectangular frame has sliding grooves along its length at the middle of its left and right sides. The two ends of the sliding rod are slidably positioned within these grooves. Multiple positioning grooves are formed at the top of the left and right sides of the rectangular frame, symmetrically arranged. A first fastener is used to engage with one of these positioning grooves. This structure allows the sliding rod to slide within the rectangular frame, and the cooperation of the first fastener and the positioning grooves fixes the position of the sliding rod relative to the rectangular frame.

[0011] The first fastener includes a C-shaped locking block and a spring. Limiting grooves are formed at both ends of the slide rod. The lower clamping edge of the C-shaped locking block is movably inserted into the limiting groove, and the lower clamping edge of the C-shaped locking block is connected to the inner end of the limiting groove via a spring. When the spring is in its natural state, the upper clamping edge of the C-shaped locking block is engaged in one of its positioning grooves. Through the structure of the first fastener, the C-shaped locking block is elastically connected to the slide rod, and when the spring automatically returns, it inserts into the positioning groove, thus fixing the position of the slide rod.

[0012] The second fastener includes two C-shaped clamps for securing it to the slide rod. One end of each C-shaped clamp is hinged, and the other end is fixed with bolts. The support rod is fixed to the upper C-shaped clamp. This structure allows for easy adjustment of the second fastener's position on the slide rod by adjusting the tightness of the bolts.

[0017] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0018] Reference Figure 1-3 This application discloses a multifunctional hoisting tool, including a fixed frame. Multiple sliding rods 3 are slidably arranged at the bottom of the fixed frame. Each sliding rod 3 has a first fastener 4 connected to both ends. The first fastener 4 is used to snap onto the fixed frame. Multiple second fasteners are slidably arranged on each sliding rod 3. Each second fastener is connected to a support rod 31. Lifting lugs 21 for connecting a hoisting mechanism are fixed at both ends of the top of the fixed frame.

[0019] In this embodiment, the fixed frame includes a rectangular frame 1 at the bottom and a hoisting frame 2 fixed at the front and rear ends of the rectangular frame 1. The hoisting frame 2 is a trapezoidal iron frame, and the lifting lugs 21 are fixed to the top of the trapezoidal iron frame. The steel wire rope of the hoisting mechanism is connected through the lifting lugs 21 to increase the structural stability of the fixed frame during hoisting. The rectangular frame 1 serves as the base for fixing the hoisting frame 2, which facilitates the hoisting of the fixed frame through the lifting lugs 21.

[0020] In this embodiment, sliding grooves 12 are provided at the middle positions of the left and right sides of the rectangular frame 1 along the length direction. The two ends of the slide rod 3 are slidably disposed in the sliding grooves 12 on both sides. Multiple positioning grooves 11 are provided at the top of the left and right sides of the rectangular frame 1 along the length direction of the rectangular frame 1. The spacing between each positioning groove 11 is equal. The positioning grooves 11 on the left and right sides of the rectangular frame 1 are symmetrically arranged. The lower end of the first fastener 4 is elastically connected to the slide rod 3, and the upper end of the first fastener 4 is used to engage in one of its positioning grooves 11. Specifically, the first fastener 4 includes a C-shaped locking block 41 and a spring 42. The upper clamping edge of the C-shaped locking block 41 is set to a shape and size that matches the positioning groove 11, so that the upper clamping edge of the C-shaped locking block 41 can... The slide rod 3 is inserted into the positioning groove 11. Both ends of the slide rod 3 are provided with a rectangular limiting groove 34. The lower clamping edge of the C-shaped locking block 41 is set to match the shape and size of the limiting groove 34. The lower clamping edge of the C-shaped locking block 41 is movably inserted into the limiting groove 34, and the end of the lower clamping edge of the C-shaped locking block 41 is connected to the inner end of the limiting groove 34 by a spring 42. The elastic deformation direction of the spring 42 is parallel to the axis of the slide rod 3. When the spring 42 is in its natural state, the upper clamping edge of the C-shaped locking block 41 is engaged in one of its positioning grooves 11. Through the above structure, the slide rod 3 can be slidably set in the rectangular frame 1. At the same time, the position of the slide rod 3 and the rectangular frame 1 can be fixed by the cooperation of the first fastener 4 and the positioning groove 11.

[0021] In this embodiment, the second fastener includes two C-shaped clamps 32, which are used to clamp onto the slide rod 3. One end of each C-shaped clamp is hinged, and the other end is fixed by bolts 33. The support rod 31 is fixed to the upper C-shaped clamp 32. This structure facilitates adjusting the position of the second fastener on the slide rod 3 by adjusting the tightness of the bolts 33. In use, pull the C-shaped blocks 41 on both sides simultaneously. At this time, the lower clamping edge of the C-shaped blocks 41 moves outward, causing the upper clamping edge of the C-shaped blocks 41 to move out of the positioning groove 11. At this time, the two ends of the slide rod 3 can move back and forth in the sliding groove 12. Move the slide rod 3 to the desired position and release the C-shaped blocks 41 on both sides. Under the action of the spring 42, the C-shaped blocks 41 on both sides move inward, so that the upper clamping edge of the C-shaped blocks 41 on both sides inserts into the positioning groove 11 at the desired position. This allows the distance between the support rods 31 of different slide rods 3 to be adjusted through each slide rod 3. Then loosen the bolt 33 to increase the distance between the two C-shaped clamps 32. At this time, the position of the second fastener on the slide rod 3 can be adjusted, thereby adjusting the spacing between the support rods 31 on the same slide rod 3.

[0022] The multi-functional hoisting tool of this embodiment can be used to hoist various prefabricated components and accessories, such as prefabricated wall panels and prefabricated stirrups. When hoisting prefabricated wall panels using the hoisting tool of this embodiment, multiple wall panels can be stacked vertically between the support rods 31 on both sides and the wall panels can be clamped by the support rods 31. Alternatively, each wall panel can be inserted horizontally between the support rods 31 of two adjacent sliding rods 3 to hoist each wall panel separately. When hoisting prefabricated stirrups using the hoisting tool of this embodiment, each stirrup can be put on the support rod 31.

[0023] This utility model's multifunctional lifting tool uses a fixed frame as the lifting base, with lifting lugs 21 on both sides for connecting the lifting mechanism to facilitate lifting. Multiple support rods 31 serve as limiting elements for prefabricated parts or accessories on the fixed frame to prevent them from falling during lifting. The support rods 31 are slidably mounted on slide rods 3 via second fasteners, and the slide rods 3 are slidably mounted on the fixed frame, making it easy to adjust the position of each support rod 31 so that it can be used to clamp and place different prefabricated parts or accessories.
