Technical Field
[0001] The utility model relates to the technical field of hoisting machines for construction projects, and particularly relates to a hoisting machine for construction projects. Background Art
[0002] In the field of modern construction projects, vertical transportation is a crucial operation link. With the rapid progress of urban construction, the building scale is expanding day by day, the number of floors is increasing continuously, and the demand for efficient and safe transportation of building materials, construction equipment and personnel is becoming more and more urgent. In the early days, the vertical transportation means in construction projects were relatively simple, often relying on manual handling or simple rope hoisting devices. These methods are inefficient, not only consuming a large amount of manpower, but also having a very limited transportation volume, making it difficult to meet the needs of large-scale building construction. For example, in small building projects, construction workers need to consume a lot of physical strength to successively pull a small amount of materials such as bricks and cement to the construction floor through ropes. The work intensity is high and the progress is slow. With the development of industrial technology, hoisting machines for construction projects came into being.
[0003] Most hoisting machines for construction projects usually consist of a frame, a driving device, a transmission device, and a working hanging basket. During operation, first place the goods in the hanging basket, start the motor, and drive the hanging basket to rise or fall along the frame guide rail through a reducer and a transmission device. After reaching the designated floor, stop the motor and unload the goods to complete one transportation process.
[0004] In the prior art, when some hoisting machines transmit goods through a hanging basket, due to the vibration of the driving source during movement, the hanging basket itself vibrates, which in turn causes the goods to shake, reducing the stability during transportation, causing the goods to collide with the hanging basket and rub against the outside of the goods, resulting in damage to the quality of the goods. Therefore, in view of the above deficiencies, a hoisting machine for construction projects is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a hoisting machine for construction projects is proposed, aiming to improve the problems of poor stability and easy damage to goods of the hoisting machine in the prior art during the transportation of goods.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A hoist for construction engineering includes two support plates. A support frame is fixedly connected to the top of the two support plates. An electric push rod is fixedly connected to the front side of the top of the support frame. A receiving plate is fixedly connected to the drive end of the electric push rod. Two load plates are slidably connected to the front side of the receiving plate. A turning rod is threadedly connected to the front side of the load plate. A sliding block is rotatably connected to the rear end of the turning rod. A receiving block is fixedly connected to the top of the sliding block. Multiple receiving holes are opened inside the receiving block. A strong spring is installed inside the receiving holes. A clamping assembly is slidably connected to the rear inner wall of the receiving block.
[0008] Furthermore, a fixing rod is fixedly connected to the inner left end of the support frame, a motor is fixedly connected to the rear side of the receiving plate, a rotating rod is fixedly connected to the drive end of the motor, connecting rods are rotatably connected to the left and right sides of the rotating rod, connecting blocks are fixedly connected to the far sides of the two connecting rods, and the front end of the connecting block is fixedly connected to the rear end of the carrying plate.
[0009] Furthermore, the clamping assembly includes multiple sliding rods, with a limiting plate fixedly connected to the front end of each sliding rod, and a clamping plate fixedly connected to the rear end of each sliding rod. The outer side of each sliding rod is slidably connected to the rear inner wall of the receiving block. One end of the powerful spring is fixedly connected to one side of the inside of the receiving hole, and the other end of the powerful spring is fixedly connected to the front end of the limiting plate. The outer side of the limiting plate is slidably connected to the inside of the receiving hole.
[0010] Furthermore, the bottom end of the support plate is fixedly connected to multiple casters, and the front end of the turning rod is fixedly connected to a turning disc.
[0011] Furthermore, the outer side of the sliding block is slidably connected to the inside of the carrying plate, and the bottom end of the receiving block is slidably connected to the top end of the carrying plate.

[0013] Furthermore, two sliding holes are provided on the front side of the receiving plate, and the outer part of the connecting block is slidably connected to the inside of the sliding holes.
[0014] Furthermore, a triangular connecting block is fixedly connected to the rear top of the support plate, the front side of the triangular connecting block is fixedly connected to the rear side of the support frame, and the left side of the receiving plate is slidably connected to the outside of the fixed rod.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, when the goods are placed on the carrying plate, the turning disc is turned so that the turning rod moves the receiving block toward the goods. At this time, the clamping plate will come into contact with the goods, so that the sliding rod drives the limiting disc to squeeze the strong spring. The resulting rebound force clamps the goods, which can improve the stability of the goods during transportation, reduce the friction of the goods caused by vibration, and thus effectively reduce the risk of damage to the goods, ensuring that the goods are transported to the designated floor in good condition.
[0017] 2. In this utility model, by starting the motor, the rotating rod drives the connecting rod to move, which in turn causes the connecting block to slide inside the sliding hole, thereby adjusting the distance between the two carrying plates. This allows it to adapt to the transportation of goods of different sizes and improves the adaptability of the hoist to building materials of different specifications. Attached Figure Description

A receiving plate 4 is fixedly connected to the driving end of the electric push rod 3 to provide additional receiving space. Multiple universal wheels 5 are fixedly connected to the bottom of the support plates 1 to facilitate the movement of the entire device. Two loading plates 6 are slidably connected to the front of the receiving plate 4 to serve as a platform for carrying goods. A turning rod 7 is threadedly connected to the front of the loading plate 6. A turning disc 8 is fixedly connected to the front end of the turning rod 7. The design of the turning disc 8 conforms to ergonomics, allowing the operator to comfortably apply force when holding it. A sliding block 9 is rotatably connected to the rear end of the turning rod 7 to provide a connecting function. The outer side of the sliding block 9 is slidably connected to the inside of the loading plate 6. A receiving block 10 is fixedly connected to the top of the sliding block 9 to provide additional receiving space. The bottom end of the receiving block 10 is slidably connected to the top of the loading plate 6.
[0026] The receiving block 10 has multiple receiving holes 11 inside. A strong spring 12 is installed inside the receiving hole 11 to provide spring force and rebound force. A clamping assembly is slidably connected to the rear inner wall of the receiving block 10. The clamping assembly includes multiple sliding rods 13. The front end of the sliding rod 13 is fixedly connected to a limiting plate 14, which can effectively limit the sliding range of the sliding rod 13. The rear ends of the multiple sliding rods 13 are fixedly connected to a clamping plate 15, which can closely contact the goods and provide a stable clamping force to the goods. The outer side of the sliding rod 13 is slidably connected to the rear inner wall of the receiving block 10. One end of the strong spring 12 is fixedly connected to the inside side of the receiving hole 11, and the other end of the strong spring 12 is fixedly connected to the front end of the limiting plate 14. The outer side of the limiting plate 14 is slidably connected to the inside of the receiving hole 11.
[0027] Reference Figure 1 , Figure 2 and Figure 4Two sliding holes 16 are provided on the front side of the receiving plate 4, and two elongated holes 17 are provided on the top of the carrying plate 6 to provide additional sliding tracks. The outer top of the sliding block 9 is slidably connected to the inside of the elongated hole 17. A fixing rod 19 is fixedly connected to the inner left end of the support frame 2. A triangular connecting block 18 is fixedly connected to the rear side of the top of the support plate 1. The front side of the triangular connecting block 18 is fixedly connected to the rear side of the support frame 2. The left side of the receiving plate 4 is slidably connected to the outside of the fixing rod 19. The fixing rod 19 provides a stable support point for the left side of the receiving plate 4, so that the receiving plate 4 will not tilt during lifting or translating. A motor 20 is fixedly connected to the rear side of the receiving plate 4 to provide driving force. A rotating rod 21 is fixedly connected to the driving end of the motor 20 to provide a connecting function. A connecting rod 22 is rotatably connected to the inside of both the left and right sides of the rotating rod 21. A connecting block 23 is fixedly connected to the far side of the two connecting rods 22. The outside of the connecting block 23 is slidably connected to the inside of the sliding hole 16. The front end of the connecting block 23 is fixedly connected to the rear end of the carrying plate 6.
[0028] Working principle: First, multiple casters 5 are used to push the hoist to the designated loading position to easily move the equipment. At this time, the two loading plates 6 are in the initial spacing state, the electric push rod 3 is in the retracted state, and the receiving plate 4 fixedly connected to its drive end is in a lower position, which is convenient for loading goods.
[0029] Then, building materials and other goods are placed on the carrying plate 6. Next, the rotating disc 8 is turned, which drives the rotating rod 7 to rotate, thereby causing the sliding block 9 to slide backward inside the carrying plate 6. This causes the receiving block 10 to move backward and closer to the goods. As the receiving block 10 moves, the clamping plate 15 comes into contact with the goods. The goods exert a reverse force on the clamping plate 15, causing the clamping plate 15 to drive the sliding rod 13 forward. The sliding rod 13 slides on the rear inner wall of the receiving block 10, while simultaneously causing the front-end fixed limiting disc 14 to slide forward inside the receiving hole 11. This compresses the strong spring 12 inside the receiving hole 11. The rebound force generated by the strong spring 12 acts on the limiting disc 14, causing the clamping plate 15 to tightly clamp the goods.
[0030] If different sized goods are encountered and the spacing between the carrying plates 6 needs to be adjusted, the motor 20 is started. The drive end of the motor 20 drives the rotating rod 21 to rotate. The connecting rod 22, which is rotatably connected to the left and right sides of the rotating rod 21, moves with the rotation of the rotating rod 21. The connecting rod 22 drives the connecting block 23 to slide inside the sliding hole 16. The front end of the connecting block 23 is fixedly connected to the rear end of the carrying plate 6, thereby driving the two carrying plates 6 to adjust the spacing between them, which can adapt to the transportation of goods of different sizes.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
