Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a hoisting tool for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings and turning the lines on the design drawings into physical objects at designated locations. During the construction process, different types of boards are used, and the boards need to be transported. During transport, the boards need to be hoisted to suitable positions, which requires the use of hoisting equipment to achieve the hoisting operation.

[0003] A search revealed a construction hoisting device with application publication number CN217780501U, comprising a crossbeam with a sliding cavity inside. Threaded rods are rotatably connected to both ends of the inner wall of the sliding cavity. A threaded sleeve is threadedly connected to the outside of the threaded rods. A spring chamber is welded to the lower surface of the threaded sleeve, and a slider is slidably connected inside the spring chamber. A spring is welded to the upper surface of the slider, and a sliding rod is welded to the side of the slider away from the spring. A pressure-distributing plate is welded to the lower surface of the sliding rod, and a lifting rod is welded to the side of the pressure-distributing plate away from the sliding rod. A sliding hole for the lifting rod to slide is provided at the bottom of the crossbeam, and a hook is provided at the bottom of the lifting rod. The pressure-distributing plate above the sliding hole distributes the tension on the hook, minimizing the direct tension on the threaded rod from the hook and preventing deformation due to strong external forces, thus improving the service life of the device.

[0004] The existing technology has the following problems:

[0005] Traditional lifting tools mostly have a hook at one end of the cable for lifting operations. This is not convenient for lifting sheet materials, especially those of different thicknesses. It is also not convenient to quickly fix the lifting tool to the sheet material or to quickly separate the lifting tool from the sheet material after lifting, making the lifting operation quite cumbersome. Utility Model Content

[0006] The purpose of this utility model is to provide a hoisting tool for building construction to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a construction hoisting tool, comprising a fixed frame, clamping plates, and movable frames. Two clamping plates are movably installed on the inner side of the fixed frame. The outer side of each clamping plate is movably connected to the fixed frame via multiple movable plates, which are arranged vertically and parallel to each other. Two movable frames are slidably installed on the inner side of the fixed frame. Two slide rails are fixedly installed on both sides of the inner wall of the fixed frame. Both ends of each movable frame are slidably connected to the two slide rails. Both movable frames are located on top of the two clamping plates, and both clamping plates are slidably connected to the two movable frames. Fixed rods are fixedly installed on the top of each of the two movable frames, extending above the fixed frame. Two support frames are fixedly connected to the top of the fixed frame, and a fixed plate is fixedly connected between the two support frames, with the fixed plate located above the fixed rods.

[0008] By fixing the fixed plate to one end of the hoisting cable, the cable can be used to move the fixed frame for hoisting operations. Moving the fixed frame allows one side of the building material to be inserted into the frame, pushing two clamping plates upwards. A movable plate provides support for the clamping plates, allowing them to move outwards synchronously. This moves the building material to the inside of the clamping plates. Moving the fixed frame upwards and using the movable plate to support and rotate the clamping plates allows them to close and clamp the building material. This method can clamp and fix building materials of different thicknesses. The weight of the building panel drives the clamping plate downwards. The movable plate supports the clamping plate, gradually increasing the clamping force as it moves downwards to prevent it from falling off. Moving the fixing frame upwards facilitates the hoisting of the building panel. After the building panel is hoisted to the appropriate position, releasing the fixing frame downwards allows one side of the panel to push the two movable frames upwards, causing the clamping plate to move outwards. Pulling the fixing rod upwards makes it easy to remove the fixing frame from the building panel. The operation is simple and quick, improving the hoisting efficiency during construction.

[0009] Preferably, limiting frames are fixedly installed on both the front and rear sides of the fixed frame, and guide slopes are provided at the bottom of both limiting frames. The limiting frames can limit the movable plate to prevent it from tilting when it is flipped, and the guide slopes can guide the building material, making it easier for one side of the building material to extend into the inside of the fixed frame.

[0010] Preferably, the two ends of the fixing plate are fixedly connected to the two support frames by two fixing bolts, and a fixing buckle is fixedly installed on the top of the fixing plate. The fixing bolts can be used to connect and fix the fixing plate to the support frames, and the fixing buckle can be used to connect and fix the fixing plate to the hoisting cable.

[0011] Preferably, multiple fixing teeth are fixedly installed on the inner sides of both clamping plates, and a support rod is fixedly installed on the top of both fixing rods. The fixing teeth facilitate the clamping plates to clamp and fix the building material, preventing the building material from sliding during clamping and fixing, while the support rod facilitates the upward movement of the fixing rods.

[0012] Preferably, multiple bearing seats are fixedly installed on the inner wall of the fixing frame and the outer sides of the two clamping plates, respectively. Each bearing seat has a shaft fixedly installed on its inner side, and both ends of each movable plate are movably connected to two shafts. The bearing seats support and fix the shafts, and the shafts support both ends of the movable plates, while also facilitating the flipping of the movable plates.

[0013] Preferably, each movable frame has a sliding frame fixedly installed at both ends, each sliding frame is slidably connected to a slide rail, and a limiting plate is fixedly installed at the bottom of each slide rail. The sliding frame allows the two ends of the movable frame to slide up and down along the slide rail, and the limiting plate can limit the sliding frame to prevent it from detaching from the slide rail.

[0014] Preferably, the top of the fixing frame has two sliding grooves, and each fixing rod is located inside one of the sliding grooves and slidably connected to the sliding groove. The sliding grooves allow the fixing rod to slide up and down easily.

[0015] Preferably, each of the two movable frames has a movable groove on its inner side, and two sliders are fixedly connected to the top of each clamping plate. Each pair of sliders is located inside the two movable grooves and is slidably connected to them. The movable grooves facilitate the clamping plates to move the sliders left and right, and also facilitate the clamping plates to move the movable frames up and down when they move. The movable frames allow the two clamping plates to move synchronously.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By employing a system of fixed frames, movable plates, clamping plates, and the coordinated operation of the movable frame and fixed rods, and by securing one end of the fixed plate to the hoisting cable, the cable can move the fixed frame to facilitate hoisting operations. Moving the fixed frame allows one side of the building material to be inserted into it, pushing the two clamping plates upwards. Simultaneously, the clamping plates move outwards, moving the building material to the inside of the clamping plates. By further moving the fixed frame upwards, the movable plate supports and rotates the clamping plates, allowing them to clamp and secure the building material. This system can accommodate building materials of varying thicknesses. The building panels are clamped and fixed, and the weight of the building panels drives the clamping plate to move downwards. The clamping plate is supported by a movable plate, which gradually increases the clamping force as the plate moves downwards, preventing it from falling off. This facilitates the hoisting operation of the building panels. After the building panels are hoisted to the appropriate position, the fixing frame is loosened and moved downwards, which causes one side of the panel to push the two movable frames upwards, which in turn moves the clamping plate outwards. By pulling the fixing rod upwards, the fixing frame can be easily removed from the building panels. The operation is simple and quick, improving the hoisting efficiency during construction.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides, for example Figure 1-4The construction hoist shown includes a fixed frame 1, clamping plates 9, and movable frames 11. Two clamping plates 9 are movably installed on the inner side of the fixed frame 1. The outer side of each clamping plate 9 is movably connected to the fixed frame 1 through multiple movable plates 8. The multiple movable plates 8 are arranged vertically and parallel to each other. Two movable frames 11 are slidably installed on the inner side of the fixed frame 1. Two slide rails 14 are fixedly installed on both sides of the inner wall of the fixed frame 1. The two ends of each movable frame 11 are slidably connected to the two slide rails 14. Both movable frames 11 are located on top of the two clamping plates 9. The two clamping plates 9 are slidably connected to the two movable frames 11. Fixed rods 12 are fixedly installed on the top of each of the two movable frames 11. Both fixed rods 12 extend above the fixed frame 1. Two support frames 2 are fixedly connected to the top of the fixed frame 1. A fixed plate 3 is fixedly connected between the two support frames 2. The fixed plate 3 is located above the fixed rods 12.

[0025] Limiting frames 6 are fixedly installed on the front and rear sides of the fixed frame 1, and guide slopes 7 are provided at the bottom of both limiting frames 6;

[0026] The two ends of the fixing plate 3 are fixedly connected to the two support frames 2 by two fixing bolts 4 respectively, and the top of the fixing plate 3 is fixedly installed with a fixing buckle 5;

[0027] Multiple fixing teeth 10 are fixedly installed on the inner side of both clamping plates 9, and a support rod 13 is fixedly installed on the top of the two fixing rods 12;

[0028] Multiple bearing seats 17 are fixedly installed on the inner wall of the fixed frame 1 and the outer sides of the two clamping plates 9 respectively. Each bearing seat 17 has a shaft 18 fixedly installed on its inner side. The two ends of each movable plate 8 are movably connected to the two shafts 18 respectively.

[0029] Each movable frame 11 has a sliding frame 16 fixedly installed at both ends, each sliding frame 16 is slidably connected to a slide rail 14, and each slide rail 14 has a limit plate 15 fixedly installed at the bottom.

[0032] The working principle of the construction hoisting tool based on the embodiment is as follows: by fixing the fixing buckle 5 to one end of the hoisting cable, the cable can drive the fixed frame 1 to move to realize the hoisting operation. By driving the fixed frame 1 to move, one side of the building panel is inserted into the inside of the fixed frame 1. The building panel pushes the two clamping plates 9 to move upward. The movable plate 8 provides movable support for the clamping plates 9, so that the clamping plates 9 can move outward synchronously when moving, and the building panel can be moved to the inside of the clamping plates 9.

[0033] By moving the fixed frame 1 upward, the clamping plate 9 can be supported and rotated by the movable plate 8, so that the clamping plate 9 can be moved to clamp and fix the building material. It can clamp and fix building materials of different thicknesses. The weight of the building material can be used to move the clamping plate 9 downward. By supporting the clamping plate 9 with the movable plate 8, the clamping force of the clamping plate 9 can be gradually increased when it moves downward, so as to avoid falling off.

[0034] By moving the fixed frame 1 upward, it is convenient to hoist the building panels. After the building panels are hoisted to a suitable position, by loosening the fixed frame 1 and moving it downward, one side of the panel can push the two movable frames 11 upward, which can drive the clamping plate 9 to move outward. By pulling the fixed rod 12 upward, it is convenient to remove the fixed frame 1 from the building panels. The operation is simple and quick, improving the hoisting efficiency during construction.
