Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a hoisting device for building construction. Background Technology

[0002] Construction hoisting equipment is a type of mechanical equipment used on construction sites for lifting, moving, and installing heavy objects. It typically consists of a metal structure, a power system, a control system, and hoisting accessories. It features high load-bearing capacity, flexible operation, and safety and reliability. Hoisting equipment improves construction efficiency and reduces labor intensity, making it an indispensable piece of equipment in modern construction.

[0003] Traditional lifting equipment is usually designed for specific types of lifting tasks, making it difficult to adapt to various complex construction environments and different lifting requirements. In addition, traditional lifting equipment may lack effective object stabilization and clamping mechanisms, which can cause objects to sway, tilt, or fall off during the lifting process, thereby increasing construction risks and uncertainties.

[0004] Therefore, those skilled in the art have provided a hoisting device for building construction to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hoisting device for construction. A first servo motor drives a unidirectional threaded rod to control the movement of a first sliding block, thereby adjusting the horizontal position of the first protective shell, winding rollers, and mounting frame. A second servo motor, through a gear meshing design, ensures that the two winding rollers work synchronously, causing the hoisting rope to wind in opposite directions and smoothly adjust the height of the mounting frame. Furthermore, a third servo motor drives a bidirectional threaded rod, causing the second sliding block to move flexibly back and forth within the mounting groove, allowing the clamping plate to adapt to the hoisting requirements of different objects and achieve stable clamping. This multi-directional adjustment function not only improves the accuracy and efficiency of hoisting operations but also adapts to various complex construction environments, meeting the needs of different hoisting tasks.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hoisting device for building construction includes a base, a first protective shell, and a mounting frame. A second servo motor is fixedly connected to the inner top surface of the first protective shell. The output end of the second servo motor passes through the first protective shell to its lower end and is fixedly connected to a driving helical gear. The front and rear ends of the outer wall of the driving helical gear are gear-meshing driven helical gears. A take-up roller is fixedly connected to the outer wall of the driven helical gear at the end away from the center of the first protective shell. A hoisting rope is wound around the outer wall of the middle part of the take-up roller. Both sides of the lower end of the hoisting rope are fixedly connected to the upper surface of the mounting frame. A second mounting groove is opened in the middle of the lower surface of the mounting frame. A second protective shell is fixedly connected to the outer wall of the rear end of the mounting frame. A bidirectional threaded rod is provided inside the second mounting groove. A third servo motor is provided inside the second protective shell. The output end of the third servo motor passes through the mounting frame to the interior of the second mounting groove and is fixedly connected to the middle of the rear end of the bidirectional threaded rod. A second sliding block is threadedly connected to the front and rear ends of the outer wall of the bidirectional threaded rod. A clamping plate is fixedly connected to the lower end of the second sliding block.

[0008] Through the above technical solution, the gear meshing design of the second servo motor, the active helical gear and the driven helical gear ensures that the two winding rollers can work synchronously, so that the lifting rope is wound in opposite directions, thereby smoothly adjusting the height of the mounting frame. At the same time, the third servo motor drives the bidirectional threaded rod, which drives the second sliding block to move flexibly back and forth in the second mounting groove, so that the clamping plate can adapt to the lifting requirements of different objects and achieve stable clamping and fixing.

[0009] Furthermore, a hydraulic rod is fixedly connected to the middle of the upper surface of the base, and a fixing frame is provided at the upper end of the hydraulic rod. One side of the lower surface of the fixing frame is fixedly connected to the output end of the hydraulic rod. A first mounting groove is opened in the middle of the outer wall of the fixing frame. A one-way threaded rod is provided inside the first mounting groove. A first servo motor is fixedly connected to the inner wall of the other side of the first mounting groove. The output end of the first servo motor is fixedly connected to the middle of the other side of the one-way threaded rod. A first sliding block is threadedly connected to the outer wall of the one-way threaded rod. The upper surface of the first protective shell is fixedly connected to the lower end of the first sliding block. A fixing rod is rotatably connected to the outer wall of the winding roller at the end away from the center of the first protective shell. The upper end of the fixing rod is fixedly connected to the outer wall of the lower end of the first sliding block at the end away from the center of the first protective shell.

[0010] Through the above technical solution, the height of the fixed frame can be flexibly adjusted by the extension and retraction of the hydraulic rod. At the same time, the first servo motor drives the one-way threaded rod to control the movement of the first sliding block, thereby adjusting the horizontal position of the first protective shell, the winding roller and the mounting frame. This multi-directional adjustment function not only improves the accuracy and efficiency of hoisting operations, but also adapts to various complex construction environments and meets the needs of various hoisting tasks.

[0011] Furthermore, brake casters are fixedly connected to the four corners of the lower surface of the base, a counterweight is fixedly connected to one side of the upper surface of the base, and a PLC control panel is fixedly connected to the front end of the other side of the upper surface of the base.

[0012] The above technical solution uses braked casters for movement and stability, counterweights to keep the device balanced, and a PLC control panel to control the operation of the entire device.

[0013] Furthermore, the lower front end, rear end and both sides of the hydraulic rod are fixedly connected with reinforcing blocks, and the other side of the output end of the hydraulic rod is fixedly connected with a reinforcing plate. The upper end of the reinforcing plate is fixedly connected to the lower surface of one side of the fixing frame.

[0014] The above technical solution enhances the stability of the device through the reinforcement blocks and plates.

[0015] Furthermore, the winding direction of the take-up roller is opposite;

[0016] With the above technical solution, since the two driven helical gears driven by the active helical gear rotate in opposite directions, the opposite winding direction of the winding roller can make the movement of the installation frame driven by the lifting ropes at both ends synchronized. This synchronized movement can ensure that the installation frame remains stable and balanced during the hoisting process.

[0017] Furthermore, the rear end of the third servo motor is fixedly connected to the rear end of the inner wall of the second protective shell;

[0018] The above technical solution protects the internal third servo motor with a second protective shell, preventing external dust, moisture, and other contaminants from entering.

[0019] Furthermore, the front and rear ends of the bidirectional threaded rod are rotatably connected to the front and rear ends of the inner wall of the second mounting groove, the outer walls of the second sliding block are slidably attached to the inner wall of the second mounting groove, and the upper surface of the clamping plate is slidably attached to the lower surface of the mounting bracket.

[0020] The above technical solution and design make the clamping process of the second sliding block driving the clamping plate more stable.

[0021] Furthermore, one side of the one-way threaded rod is rotatably connected to the inner wall of one side of the first mounting groove, the outer wall of the upper end of the first sliding block is slidably attached to the inner wall of the first mounting groove, and the inner wall of the lower end of the first sliding block is slidably attached to the outer wall of the lower end of the fixing frame.

[0022] The above technical solution and design make the movement of the first sliding block, the first protective shell and the lower part more stable.

[0023] This utility model has the following beneficial effects:

[0024] 1. The hoisting device for building construction proposed in this utility model ensures that the two winding rollers can work synchronously through the gear meshing design of the second servo motor, the driving helical gear and the driven helical gear, so that the hoisting rope is wound in opposite directions, thereby smoothly adjusting the height of the mounting frame. At the same time, the third servo motor drives the bidirectional threaded rod, which drives the second sliding block to move flexibly back and forth in the second mounting groove, so that the clamping plate can adapt to the hoisting requirements of different objects and achieve stable clamping and fixing.

[0025] 2. The hoisting device for building construction proposed in this utility model can flexibly adjust the height of the fixed frame by extending and retracting the hydraulic rod. At the same time, the first servo motor drives the one-way threaded rod to control the movement of the first sliding block, thereby adjusting the horizontal position of the first protective shell, the winding roller and the mounting frame. This multi-directional adjustment function not only improves the accuracy and efficiency of hoisting operations, but also adapts to various complex construction environments and meets the needs of various hoisting tasks.

A second servo motor 5 is fixedly connected to the inner top surface of the first protective shell 403. The output end of the second servo motor 5 passes through the first protective shell 403 to the lower end of the first protective shell 403 and is fixedly connected to a driving helical gear 501. The front and rear ends of the outer wall of the driving helical gear 501 are gear-meshing with driven helical gears 502. A winding roller 6 is fixedly connected to the outer wall of the driven helical gear 502 at the end away from the center of the first protective shell 403. A hoisting rope 601 is wound around the outer wall of the middle part of the winding roller 6.

The system includes a bidirectional threaded rod 801 and a third servo motor 8 inside the second protective shell 702.

The front and rear ends of the outer wall of the bidirectional threaded rod 801 are threadedly connected to second sliding blocks 802. The lower ends of the second sliding blocks 802 are fixedly connected to clamping plates 803. The gear meshing design of the second servo motor 5, the driving helical gear 501, and the driven helical gear 502 ensures that the two winding rollers 6 can work synchronously, so that the lifting rope 601 is wound in opposite directions, thereby smoothly adjusting the height of the mounting frame 7. At the same time, the third servo motor 8 drives the bidirectional threaded rod 801, causing the second sliding block 802 to move flexibly back and forth in the second mounting groove 701, so that the clamping plate 803 can adapt to the lifting requirements of different objects and achieve stable clamping and fixing.

Fixed rods 602 are rotatably connected to the outer wall of the end away from the center of the first protective shell 403. The upper end of the fixed rods 602 is fixedly connected to the outer wall of the lower end of the first sliding block 402 away from the center of the first protective shell 403. The height of the fixed frame 3 can be flexibly adjusted by the extension and retraction of the hydraulic rod 2. At the same time, the first servo motor 4 drives the one-way threaded rod 401 to control the movement of the first sliding block 402, thereby adjusting the horizontal position of the first protective shell 403, the winding roller 6 and the mounting frame 7. This multi-directional adjustment function not only improves the accuracy and efficiency of hoisting operations, but also adapts to various complex construction environments and meets the needs of various hoisting tasks.

[0035] Reference Figure 1 , Figure 2 and Figure 3Brake casters 101 are fixedly connected to the four corners of the lower surface of the base 1. A counterweight 103 is fixedly connected to one side of the upper surface of the base 1, and a PLC control panel 102 is fixedly connected to the front end of the other side of the upper surface of the base 1. The brake casters 101 are used for the movement and stability of the device, the counterweight 103 is used to keep the device balanced, and the PLC control panel 102 is used to control the operation of the entire device.

A reinforcing plate 202 is fixedly connected to the other side of the output end of the hydraulic rod 2. The upper end of the reinforcing plate 202 is fixedly connected to the lower surface of one side of the fixed frame 3. The reinforcing blocks 201 and the reinforcing plate 202 enhance the stability of the device. The winding direction of the take-up roller 6 is opposite. Since the two driven helical gears 502 driven by the active helical gear 501 rotate in opposite directions, the opposite winding direction of the take-up roller 6 can make the movement of the mounting frame 7 driven by the suspension ropes 601 at both ends synchronized. This synchronized movement can ensure safety. The mounting frame 7 maintains stability and balance during hoisting. The rear end of the third servo motor 8 is fixedly connected to the rear end of the inner wall of the second protective shell 702. The second protective shell 702 protects the internal third servo motor 8 from external dust, moisture, etc. The front and rear ends of the bidirectional threaded rod 801 are rotatably connected to the front and rear ends of the inner wall of the second mounting groove 701. The outer wall of the second sliding block 802 is slidably attached to the inner wall of the second mounting groove 701. The upper surface of the clamping plate 803 is flush with the lower surface of the mounting frame 7. The sliding contact design makes the clamping process of the second sliding block 802 driving the clamping plate 803 more stable. One side of the one-way threaded rod 401 is rotatably connected to the inner wall of one side of the first mounting groove 301.

This design makes the movement of the first protective shell 403 and the lower part of the first sliding block 402 more stable.

[0036] Working principle: The height of the fixed frame 3 is adjusted by the hydraulic rod 2 to achieve vertical positioning of the device. The second servo motor 5 drives the active helical gear 501 to mesh with the driven helical gear 502, so that the two winding rollers 6 work synchronously. The height of the mounting frame 7 is smoothly adjusted by the winding rope 601 in opposite directions. At the same time, the third servo motor 8 drives the bidirectional threaded rod 801, which drives the second sliding block 802 to move back and forth in the second mounting groove 701, so that the clamping plate 803 can adapt to the lifting requirements of different objects and achieve stable clamping. The brake universal wheel 101 on the base 1 provides movement and stability functions. The counterweight block 103 keeps the device balanced. The PLC control panel 102 realizes the overall operation control. The reinforcing block 201 and reinforcing plate 202 enhance the stability of the device.
