Description

Technical Field

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

[0002] In the complex process of building construction, various building materials often need to be hoisted from the ground to specific heights to meet the needs of different construction stages. For example, when constructing multi-story or high-rise buildings, basic building materials such as cement, bricks, and steel bars, as well as large prefabricated components, doors, and windows, must be precisely moved to the building platform at the corresponding height for subsequent installation and construction operations.

[0003] The use of hoisting equipment for building materials has drawbacks, such as the difficulty in achieving precise multi-directional movement, which seriously affects construction efficiency and quality. Traditional hoisting equipment, such as tower cranes, is mainly designed to meet the needs of large-scale and heavy-duty hoisting, with a single mode of movement, making it difficult to make fine adjustments in complex environments. Modern construction environments are becoming increasingly complex, and scenarios such as high-rise buildings and underground projects have extremely high requirements for hoisting precision. However, due to design limitations and technological lag, traditional equipment is unable to meet the needs of multi-directional and detailed movement. In addition, the varying skill levels of operators further exacerbate the difficulty of precise control, leading to multiple adjustments during construction, wasting time and manpower, and even affecting material positioning and construction quality.

[0004] In response to this technical problem, this application proposes a hoisting device for building construction materials. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction material hoisting device. This device allows for precise adjustment of the material being hoisted at the mobile platform during positioning, facilitating accurate placement of the material at the construction site, ensuring stability during the clamping process, and enabling the device to maintain a continuous fixing effect on the material during hoisting operations.

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

[0007] A construction material hoisting device includes a support platform. A fixed frame is fixedly connected to the top of the support platform. Universal wheels are fixedly connected to the front and rear sides of the bottom of the support platform at both ends. A second motor is fixedly connected to the front end of the inner wall of the fixed frame. A movable frame is connected to the drive end of the second motor via a transverse assembly. A first motor is fixedly connected to the rear end of the inner wall of the fixed frame. A second screw is connected to the drive end of the first motor via a longitudinal assembly. A movable platform is threadedly connected to the outer wall of the second screw. A connecting frame is connected to the bottom end of the movable platform via a retractable assembly. A sliding tube is fixedly connected to the bottom end of the connecting frame. A clamping claw is connected to the outer wall of the sliding tube via a clamping assembly. A controller is installed on the right end of the support platform.

[0008] Furthermore, the transverse assembly includes a screw rod fixedly connected to the drive end of the second motor, the front end of the movable frame is threadedly connected to the outer wall of the screw rod, and the outer wall of the movable frame is slidably connected to the inner wall of the fixed frame.

[0009] Furthermore, the longitudinal assembly includes a hexagonal rod fixedly connected to a drive end of the motor, and a transition ring is slidably connected to the outer wall of the hexagonal rod.

[0010] Furthermore, a helical gear is fixedly connected to the outer wall of the adapter ring, and a helical gear is fixedly connected to the right end of the screw. The helical gear and the helical gear are meshed together.

[0011] Furthermore, the shrinking assembly includes an electric take-up wheel installed at the bottom of the moving platform, with a connecting rope fixedly connected to the drive end of the electric take-up wheel, and the other end of the connecting rope fixedly connected to the top of the connecting frame.

[0012] Furthermore, the clamping assembly includes traction frames rotatably connected to both ends of the slide tube, with the opposite ends of the traction frames rotatably connected to the top of the clamping claws.

[0013] Furthermore, both ends of the connecting frame are slidably connected to slide plates, the bottom end of the slide plates is fixedly connected to a fixing ring, the inner wall of the fixing ring is fixedly connected to a positioning plate, and the clamping claws are rotatably connected to the left and right ends of the fixing ring respectively.

[0014] Furthermore, a second adapter ring is rotatably connected to the bottom end of the inner wall of the groove tube, a locking rod is slidably connected to the inner wall of the second adapter ring, and a central column is fixedly connected to the top end of the locking rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the starting motor 2 drives the screw 1 to move the moving frame along the fixed frame, so that the moving frame moves the moving platform laterally. When the motor 1 drives the hexagonal rod to rotate, the rotating ring 1 drives the hexagonal gear 2 through the helical gear 1, causing the screw 2 to rotate. The screw 2 then moves the moving platform longitudinally, so that the material hoisted at the moving platform can be precisely adjusted during positioning, making it convenient to place the material accurately at the construction site.

[0017] 2. In this utility model, the connecting rope is lowered by the electric winding wheel, causing the connecting frame to drive the fixing ring to contact the material. After contact, the connecting frame moves along the slide plate. The clamping rod of the central column inside the slide tube is triggered to rotate by the reverse force, locking into the positioning plate. The slide tube drives the clamping claw to retract and clamp the material through the traction frame. When resetting, the clamping rod maintains the locked state to ensure clamping stability and the stability of the clamping process. This allows the device to maintain the fixing effect on the material during hoisting operations, significantly improving the safety and operational efficiency of high-altitude hoisting.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a construction material hoisting device, including a support platform 1, a fixed frame 3 fixedly connected to the top of the support platform 1, universal wheels 2 fixedly connected to the bottom of the support platform 1 on both the left and right ends, a motor 5 fixedly connected to the front end of the inner wall of the fixed frame 3, a screw 7 fixedly connected to the drive end of the motor 7, a movable frame 8 threadedly connected to the front end of the screw 7, the outer wall of the movable frame 8 slidably connected to the inner wall of the fixed frame 3, a motor 4 fixedly connected to the rear end of the inner wall of the fixed frame 3, a hexagonal rod 6 fixedly connected to the drive end of the motor 4, a transition ring 9 slidably connected to the outer wall of the hexagonal rod 6, a movable platform 11 threadedly connected to the outer wall of the screw 10, a helical gear 24 fixedly connected to the outer wall of the transition ring 9, a helical gear 25 fixedly connected to the right end of the screw 10, and the helical gear 24 and the helical gear 25 are meshed together.

[0028] Specifically, in the multi-directional positioning and adjustment system of the device, when motor 5 is started, its output shaft drives screw 7 to rotate via a coupling. Utilizing the threaded transmission principle, this drives the moving frame 8 to move laterally along the linear guide rail inside the fixed frame 3. Simultaneously, the moving frame 8, through a rigid connection, pushes the upper moving platform 11 to move laterally, forming a foundation for lateral adjustment. When longitudinal fine-tuning is required, motor 4 starts, and its power is transmitted to the hexagonal rod 6 via a spline structure, driving the rod end adapter ring 9 to rotate at 30 r / min. At this time, the helical gear 24 at the end of adapter ring 9 and the helical gear 25 at the end of screw 10 form an orthogonal meshing transmission, converting the rotation direction to a vertical plane, thereby driving screw 10 to rotate around its own axis. The rotational motion of screw 10 is converted into precise displacement of the moving platform 11 along the longitudinal guide rail through the threaded pair, thus achieving precise longitudinal adjustment of the hoisted material. Through the coordinated control of the horizontal and vertical dual motors, the moving platform 11 can complete a composite movement within a range of ±50cm in a two-dimensional plane, enabling the hoisted materials to be positioned and calibrated at the millimeter level in the construction area, and finally accurately placed at the preset coordinate point, effectively solving the technical defects of the traditional hoisting device in terms of rough positioning.

[0029] Reference Figures 4-6An electric winding wheel 12 is installed at the bottom of the moving platform 11. A connecting rope 13 is fixedly connected to the drive end of the electric winding wheel 12. The other end of the connecting rope 13 is fixedly connected to the top of the connecting frame 14. A sliding tube 20 is fixedly connected to the bottom of the connecting frame 14. A traction frame 18 is rotatably connected to both ends of the sliding tube 20. The opposite ends of the traction frame 18 are rotatably connected to the top of the clamping claw 19. A controller is installed on the right end of the right support platform 1. A sliding plate 16 is slidably connected to both ends of the connecting frame 14. A fixing ring 15 is fixedly connected to the bottom of the sliding plate 16. A positioning plate 17 is fixedly connected to the inner wall of the fixing ring 15. The opposite ends of the clamping claw 19 are rotatably connected to the left and right ends of the fixing ring 15. A second adapter ring 23 is rotatably connected to the bottom of the inner wall of the sliding tube 20. A locking rod 22 is slidably connected to the inner wall of the second adapter ring 23. A central column 21 is fixedly connected to the top of the locking rod 22.

[0030] Specifically: During the operation of the construction material hoisting device, after the support platform 1 is flexibly moved to the location of the target building material by the universal wheels 2 mounted at the bottom, the operator immediately starts the drive system of the electric winding wheel 12. As the electric winding wheel 12 rotates, the connecting rope 13 wound on its surface begins to perform directional winding and unwinding operations—the connecting frame 14 connected to the end of the connecting rope 13 drives the fixing ring 15 to descend vertically until the fixing ring 15 forms stable contact with the surface of the building material. When the fixing ring 15 touches the material surface, the connecting rope 13 enters a slack state. At this time, the connecting frame 14 generates horizontal displacement in the guide groove of the slide plate 16, simultaneously driving the slide tube 20 to move downward in the vertical direction. During this process, the central column 21 set inside the slide tube 20 and its end-extending clamping rod 22 pass through the reserved holes of the positioning plate 17 in sequence and form physical contact with the surface of the fixing ring 15. As the connecting frame 14 continues to press down, the clamping rod 22 is subjected to a reverse force applied by the fixing ring 15, causing the central column 21 to undergo axial displacement inside the sliding tube 20. Due to the pre-set staggered zigzag groove structure on the inner wall of the sliding tube 20, which includes a guide rail with a 45-degree phase difference, the central column 21 is forcibly guided to rotate 90 degrees during the displacement process, ultimately causing the clamping rod 22 to lock into the slot of the positioning plate 17. This mechanical linkage triggers the sliding tube 20 to drive the two sets of clamping claws 19 to complete a centripetal retraction action through the traction frame 18, achieving a stable clamping of the building material. When the operator pulls the connecting rope 13 a second time to reset the connecting frame 14, the clamping rod 22 locked in the slot of the positioning plate 17 forms a self-locking mechanism, ensuring that the sliding tube 20 maintains the retracted state of the clamping claws 19 through the traction frame 18. This double-locking design not only ensures the stability of the clamping process but also ensures that the device maintains a continuous fixing effect on the material during hoisting operations, significantly improving the safety and operational efficiency of high-altitude hoisting.

[0031] Working principle: When the support platform 1 moves to the material position via the casters 2, the electric winding wheel 12 is activated to rotate, winding up and unwinding the connecting rope 13 connected to the electric winding wheel 12. The connecting rope 13 causes the lower fixing ring 15 of the connecting frame 14 to adhere to the building material. When the fixing ring 15 touches the material, the connecting rope 13 loosens, causing the connecting frame 14 to move at the slide plate 16, thereby causing the slide tube 20 at the connecting frame 14 to move downwards, so that the slide tube 20... The clamping rod 22 connected to the central column 21 passes through the positioning plate 17 and touches the surface of the fixing ring 15. When the connecting frame 14 continues to press down, the clamping rod 22 is subjected to a reverse force from the fixing ring 15, causing the clamping rod 22 to drive the central column 21 to move inside the slide tube 20. Due to the action of the misaligned zigzag groove provided inside the slide tube 20, the central column 21 rotates 90 degrees inside the slide tube 20, causing the clamping rod 22 to be locked at the positioning plate 17. The slide tube 20 is then pulled by the traction frame. 18 drives the clamping claw 19 to retract inward, clamping the material. Pulling the connecting rope 13 again resets the connecting frame 14. At the center column 21, the locking rod 22 engages with the positioning plate 17, fixing the connecting frame 14 and maintaining the retraction effect of the clamping claw 19 driven by the traction frame 18. This maintains the clamping claw 19's fixation of the material, facilitating material hoisting. The starting motor 25 drives the screw 1 7 to move the moving frame 8 within the fixed frame 3, causing the moving frame 8 to move the moving platform 11 laterally. When the motor 1 4 drives the hexagonal rod 6 to rotate the transition ring 9, the transition ring 9, through the helical gear 1 24, drives the helical gear 2 25, causing the screw 2 10 to rotate. This causes the screw 2 10 to move the moving platform 11 longitudinally, allowing for precise positioning of the material hoisted at the moving platform 11, facilitating accurate placement at the construction site.
