Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a prefabricated component hoisting device. Background Art

[0002] In industrialized construction, the hoisting of prefabricated components (such as structural members, floor slabs, beams, and columns) is a critical step. Currently, common hoisting devices include hoisting frames, electric hoists, wire ropes, and simple stabilization devices. With the development of industrialized construction, prefabricated components are increasingly used in construction. With their advantages of rapid construction, controlled quality, environmental protection, and energy conservation, prefabricated components have become a key development direction in the modern construction industry. However, the hoisting of prefabricated components still faces many challenges, such as low hoisting efficiency, poor safety, and low positioning accuracy.

[0003] For example, the utility model with the publication number CN116692667B discloses a hoisting device for prefabricated components of assembled buildings, including a support assembly, wherein the left and right sides of the support assembly are symmetrically provided with a clamping assembly, a pressure assembly is installed in the middle of the bottom end of the support assembly, and the bottom end of the pressure assembly is installed with an adjustment assembly, and the other end of the adjustment assembly is connected to the bottom ends of the two clamping assemblies. The present invention uses the action of the pressure assembly as a signal to trigger the reversing valve and realizes the hydraulic oil entering the interior of the temporary storage pipe under the control of its valve direction, and realizes the clamping of the two clamping assemblies by approaching to complete the prefabricated components through the action of the adjustment assembly. At the same time, the prefabricated components in different installation positions are fixed by the clamping assembly with adjustable height, so that it only needs to control the valve opening of the solenoid valve to realize the automatic fixing of the prefabricated components and adapt to different prefabricated components for fixing. The overall efficiency is high and suitable for use on the construction site.

[0004] Traditional lifting devices usually use a single-point or double-point suspension method. The electric hoist lifts the components through the wire rope. However, when lifting, moving or affected by wind, the components are prone to swing, making positioning difficult. The swing makes it difficult to accurately align the components and requires repeated adjustments, which reduces construction efficiency. Excessive swing amplitude may cause component collisions and even cause structural damage or personal injury. However, there are problems such as limited adjustment range and slow response speed. It is difficult to adapt to the lifting needs of components of different sizes, causing prefabricated components to shake and tilt during lifting, posing a huge safety hazard to the construction work of the construction project.

[0009] Preferably, the two ends of the limiting ring are arc-shaped, and a plurality of protrusions are fixedly provided on the inner wall of the limiting ring. The plurality of protrusions are made of rubber material and are in contact with the outer wall of the adjustment block.

[0010] Preferably, the spring rod is composed of a spring and a telescopic rod, the telescopic rod and the spring are in a sleeve shape, and the two ends of the spring rod are fixedly connected to the inner wall of the adjustment block and the limiting ring respectively.

[0011] Preferably, two symmetrical movable grooves are provided on the side wall of the hoisting box, and insertion grooves are provided on both symmetrical sides of the fixed plate, and circular holes are provided on the tops of the insertion grooves, and the insertion grooves are connected to the circular holes; A rectangular block is fixedly provided on one side of the two fixing plates away from the opening of the hoisting box, and the two rectangular blocks slide toward each other along the two moving grooves respectively.

[0012] Preferably, the adjustment assembly includes two groups of moving blocks arranged on both sides symmetrically of the lifting frame, two screws screwed at the centers of the two groups of moving blocks, a control motor fixedly arranged at the top ends of the two screws, and a fixed ring arranged at the center of the control motor.

[0013] Preferably, two symmetrical connecting frames are fixedly provided on one side of the limiting ring close to the moving block, and the two connecting frames are fixedly connected to the moving block.

[0014] Preferably, both ends of the screw are rotatably connected to the mounting bracket respectively, and the control motor is fixedly connected to the top of the mounting bracket.

[0015] Preferably, a slider is fixedly provided on the side wall of the moving block, and the slider slides along the slide groove. The screw threads on both sides of the fixed collar are opposite, and the two moving blocks are respectively located on both symmetrical sides of the fixed collar and make opposite movements.

[0016] Preferably, the driving assembly includes a round rod slidably sleeved inside the round hole, a driving plate fixedly arranged at the bottom of the round rod, a fixing block abutting against one side of the driving plate, a vertical plate fixedly mounted on the top and bottom of the fixing block, and a spring fixedly arranged on the vertical plate and fixedly connected to the inner wall of the hoisting box on both sides symmetrically; The driving plate is slidingly arranged inside the insertion groove, the fixed block is trapezoidal in shape and the side close to the driving plate is inclined, the fixed block and the fixed plate are fixedly connected to each other on the side close to the inner wall of the lifting box, and an L-shaped bracket is fixedly arranged on the top of the round rod, and the L-shaped bracket is fixedly connected to the side walls of the two moving blocks at the bottom.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the buffering of the shaking effect of the wire rope by arranging the cooperation of structures such as the limit ring, the adjustment block and the spring rod, etc., and drives the wire rope to be lowered by the electric hoist, driving the hoisting box to quickly clamp and fix the component. During the hoisting process, the stabilizing mechanism effectively suppresses the swing of the wire rope to prevent the component from shaking and being damaged. The adjustment block cooperates with the hoisting frame to achieve initial limiting. When the wire rope deviates, the limit ring automatically resets under the combined action of the friction resistance of the protrusion and the elastic restoring force of the spring rods on both sides. If the wire rope swings to the right, the right spring rod provides thrust and the left side applies tension to jointly offset the swing kinetic energy. The entire device integrates automatic fixing, anti-swing and spacing adjustable functions, which significantly improves the efficiency and stability of component hoisting, and solves the problem that the existing hoisting equipment is prone to swinging when lifting, moving or affected by wind, resulting in positioning difficulties and reduced construction efficiency, and the swing amplitude is too large may cause component collision, and even cause structural damage or personal injury.

[0018] The present invention facilitates the adjustment of the distance between the two limit rings by arranging the coordination of structures such as a moving block, a screw and a control motor, so as to adapt to different lifting conditions. The bidirectional screw is driven to rotate by the control motor, and the reverse threads on both sides of the fixed ring are used to drive the two moving blocks to move synchronously toward or in opposite directions, thereby adjusting the distance between the two limit rings. When it is necessary to expand the anti-sway range, the distance between the limit rings is increased; when it is necessary to improve the lifting stability, the distance is reduced, thereby achieving flexible adaptation to different lifting requirements.

[0019] The present invention facilitates the limiting and pressing of both sides of the hoisted component by setting up the coordination of structures such as the fixed plate, the hoisting box and the driving assembly, thereby improving the stability during the hoisting process. The hoisting box controls the fixing and release of the component through the wire rope. When the wire rope is pulled up, the adjusting assembly drives the moving blocks to move closer, causing the spacing between the limiting rings to shorten, so that the round rod pushes up the driving plate, and the latter's inclined surface squeezes the fixed block, forcing the fixed plates on both sides to clamp the component (spring stretching); after releasing the wire rope, the moving blocks separate, the driving plate moves down to release the squeezing, the spring rebounds to reset the fixed plate, and the component can be taken out.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 13 As shown, the present invention provides a prefabricated component hoisting device, comprising a hoisting frame 1, the hoisting frame 1 being mounted on a wall, an electric hoist 2 being fixedly mounted on the hoisting frame 1, a steel wire rope 3 being arranged at the bottom of the electric hoist 2, and the electric hoist 2 being used to drive the steel wire rope 3 to move up and down; The hoisting box 4 is fixedly arranged at the bottom of the wire rope 3 and is used to place the plates to be hoisted. The hoisting box 4 is rectangular and has fixed plates 41 on both sides symmetrically inside. The two fixed plates 41 are close to or far away from each other inside the hoisting box 4. The two fixed plates 41 are used to quickly fix the components to be hoisted; Stabilizing mechanism 5, which is located on both sides of the hanging frame 1 and is used to limit the position of the wire rope 3; The stabilizing mechanism 5 includes two limiting rings 51 located outside the steel wire rope 3, an adjusting block 52 slidably arranged inside the two limiting rings 51, two spring rods 53 located on both sides of the two adjusting blocks 52, an adjusting assembly 54 arranged on one side of the limiting ring 51, and a driving assembly 55 located inside the hoisting box 4. The adjusting component 54 is used to drive the distance between the two limit rings 51 to adjust, and the driving component 55 is used to drive the two fixed plates 41 to move closer to or away from each other. A mounting frame 11 is fixedly installed on one side of the lifting frame 1, and a slide groove 111 is provided on the mounting frame 11. The two ends of the limit ring 51 are arc-shaped, and a plurality of protrusions 511 are fixedly provided on the inner wall of the limit ring 51. The plurality of protrusions 511 are made of rubber and contact the outer wall of the adjusting block 52. The adjusting block 52 and the wire rope 3 are mutually sleeved, and the two ends of the adjusting block 52 are respectively fixedly connected to the two spring rods 53. The spring rod 53 is composed of a spring and a telescopic rod. The telescopic rod and the spring are sleeved, and the two ends of the spring rod 53 are respectively fixedly connected to the inner wall of the adjusting block 52 and the limit ring 51.

[0024] The above solution is adopted: by carrying the lifting frame 1 to the place where it is needed and then installing it on the wall with screws, the electric hoist 2 drives the wire rope 3 to relax and move downward, and then drives the lifting box 4 to move downward synchronously, and the components to be lifted are placed inside the lifting box 4 in turn, and are quickly fixed by using the fixing plates 41 on both sides, and are lifted after being fixed. During the lifting process, the stabilizing mechanism 5 can be used to limit the wire rope 3 to avoid the wire rope 3 shaking and causing damage to the components, which also poses a safety hazard. Specifically, the wire rope 3 can be initially limited by using the cooperation of the adjusting block 52 and the lifting frame 1. When the wire rope 3 shakes, the limiting ring 51 can be firmly reset under the friction of the protrusion 511 and the tension of the spring rods 53 on both sides, thereby reducing the degree of shaking. When the wire rope 3 slides to the right, the spring rod 53 on the right side will give the adjusting block 52 an elastic force, driving the adjusting block 52 to slide along the surface of the protrusion 511. At this time, the spring rod 53 on the other side will give the adjusting block 52 a pulling force, thereby making the swinging force be offset by overcoming the friction force. By setting the stabilizing mechanism 5, the effect of limiting the shaking of the wire rope 3 is achieved. At the same time, according to the specific lifting situation, the adjustment component 54 can be used to reasonably adjust the distance between the two limit rings 51 according to the length of the wire rope 3 to adapt to different lifting conditions. When the wire rope 3 drives the lifting box 4 upward to move, its rope length becomes shorter. At this time, the adjustment component 54 drives the two limit rings 51 to move closer to each other, and then drives the driving component 55 to drive the two fixed plates 41 inside the lifting box 4 closer to each other, thereby realizing rapid clamping and fixation of the component.

[0025] like Figure 6As shown, the adjustment component 54 includes two groups of moving blocks 541 arranged on both sides of the lifting frame 1 symmetrically, two screws 542 screwed at the center of the two groups of moving blocks 541, a control motor 543 fixedly arranged at the top of the two screws 542 and a fixed collar 544 arranged at the center of the control motor 543, and two symmetrical connecting frames 512 are fixedly arranged on the side of the limiting ring 51 close to the moving block 541. The two connecting frames 512 are fixedly connected to the moving block 541, and the two ends of the screw 542 are respectively rotatably connected to the mounting frame 11. The control motor 543 is fixedly connected to the top of the mounting frame 11. The side wall of the moving block 541 is fixedly provided with a slider 5411, and the slider 5411 slides along the slide groove 111. The screws 542 on both sides of the fixed collar 544 have opposite threads. The two moving blocks 541 are respectively located on the symmetrical sides of the fixed collar 544 and make opposite movements.

[0026] The above solution is adopted: the adjustment mechanism drives the screw 542 to rotate by controlling the motor 543, and uses the principle of thread transmission to achieve intelligent adjustment of the spacing of the limit rings 51. Specifically, when the control motor 543 is started, the output shaft drives the screw 542 with a bidirectional thread structure to rotate synchronously. Because the fixed collar 544 mounted on the screw 542 is processed with threads of opposite rotation on both sides, the two movable blocks 541 engaged with it produce horizontal displacement in opposite directions under the action of the threads. When the screw 542 rotates clockwise, the two movable blocks 541 move toward each other along the axial direction, driving the limit rings 51 installed on the movable blocks 541 to move closer to each other; conversely, when the screw 542 rotates counterclockwise, the two move in opposite directions, thereby expanding the spacing of the limit rings 51. This innovative design enables infinitely adjustable lifting spacing: During long-span lifting operations, the anti-sway area can be expanded by increasing the spacing between the limit rings 51, effectively suppressing the sway caused by long-distance lifting. For precision lifting, the spacing between the limit rings 51 can be reduced to form a compact constraint structure, significantly improving the overall stability of the lifting system. The entire adjustment process requires no manual intervention; the limit positions are precisely controlled solely by the forward and reverse rotation of the motor, ensuring adaptability to different working conditions and demonstrating the superiority of mechatronic design.

[0027] like Figures 10 to 12 As shown, two symmetrical movable grooves 42 are provided on the side wall of the hoisting box 4, and insertion grooves 43 are provided on both symmetrical sides of the fixed plate 41. A circular hole 44 is provided on the top of the insertion groove 43, and the insertion groove 43 is connected to the circular hole 44; A rectangular block 411 is fixedly provided on one side of the two fixing plates 41 away from the opening of the hoisting box 4, and the two rectangular blocks 411 slide toward each other along the two movable grooves 42 respectively; The driving assembly 55 includes a round rod 551 slidably mounted inside the round hole 44, a driving plate 552 fixedly mounted at the bottom of the round rod 551, a fixing block 553 abutting against one side of the driving plate 552, vertical plates 554 fixedly mounted at the top and bottom of the fixing block 553, and springs 555 fixedly mounted on the vertical plates 554 and symmetrically connected to the inner wall of the hoisting box 4. The driving plate 552 is slidably set inside the insertion groove 43, the fixed block 553 is trapezoidal in shape and the side close to the driving plate 552 is set as an inclined surface, the fixed block 553 and the fixed plate 41 are fixedly connected to each other on the side close to the inner wall of the hoisting box 4, and an L-shaped bracket 556 is fixedly set on the top of the round rod 551, and the L-shaped bracket 556 is fixedly connected to the side walls of the two moving blocks 541 at the bottom.

[0028] The above scheme is adopted: the lifting box 4 is used to quickly fix the lifting component. Specifically, the component can be placed inside the lifting box 4. When lifting upward, the wire rope 3 becomes shorter, and the adjustment component 54 drives the two moving blocks 541 to move closer to each other, driving the distance between the two limiting rings 51 to shorten. At this time, the bottom L-shaped bracket 556 can be driven to move upward, and then the round rod 551 can be driven to move upward, so that the driving plate 552 slides upward inside the insertion groove 43. Since the driving plate 552 contacts the inclined side of the fixing block 553, when the driving plate 552 moves upward, it will squeeze the fixing block 553, so that the fixing blocks 553 on both sides are close to each other, thereby driving the two fixing plates 41 to move closer to each other. The fixing plate 41 is limited by the rectangular block 411 and the moving groove 42, and can simultaneously squeeze the component toward the center to achieve a quick fixing effect. At this time, the spring 555 is When the lifting box 4 is in the lifting state, after the lifting is completed, the lifting box 4 can be lowered again. At this time, the length of the wire rope 3 becomes longer, and the adjusting component 54 drives the two moving blocks 541 to move away from each other. At this time, the bottom moving block 541 moves downward, driving the round rod 551 and the driving plate 552 to move downward synchronously, so that the driving plate 552 loses the squeeze on the fixed block 553. The fixed block 553 drives the two fixed plates 41 away from the center under the reset action of the spring 555, thereby facilitating the removal of the component. Among them, since the steel rope 3 and the moving block 541 have different driving components, their rising and falling speeds are different. The upward speed of the round rod 551 is faster than the winding of the steel rope 3. Therefore, in the process of the steel rope 3 driving the lifting box 4 to rise, it will not affect the upward movement of the round rod 551 and 552 through the L-shaped bracket 556, which can be used to squeeze the two fixed plates 41 close to each other.

[0029] The working principle and usage process of the present invention are as follows: When using the device, the operator first places the component to be hoisted steadily inside the hoisting box 4, and then starts the control motor 543 according to the actual hoisting situation, drives the screw 542 to rotate steadily, drives the moving blocks 541 on both sides to move precisely along the linear slide rail, and adjusts the distance between the two limit rings 51 through the connecting frame 512. After the adjustment is completed, the electric hoist 2 lifts the hoisting box 4 through the high-strength steel wire rope 3. During the hoisting process, when the steel wire rope 3 swings due to external force, it will drive the internal adjustment block 52 to slide in the limit ring 51, and generate controllable friction with the annularly distributed protrusions 511, effectively consuming the swing energy; at the same time, the four groups of spring rods 53 arranged symmetrically form a dynamic balance system. When the adjustment block 52 deviates from the center position, the compression side spring generates progressive resistance, and the tension side spring provides a reset tension. The two work together with the friction force to form a composite damping effect, so that the adjustment block 52 quickly returns to the center position, and the swing amplitude is significantly reduced to within ±3°. In addition, the protrusion 511 on the inner wall of the limit ring 51 further absorbs high-frequency micro-vibrations. Combined with real-time tension monitoring and dual electromagnetic braking systems, it automatically intervenes and adjusts when abnormal swing is detected. The multiple protection mechanisms significantly improve the stability and safety of the lifting process. It is particularly suitable for prefabricated building construction scenarios with high requirements for positioning accuracy. At the same time, the adjustment component 54 and the drive component 55 are linked to synchronously drive the two fixed plates 41 to move closer or farther away from each other, thereby quickly fixing the internal components of the lifting box 4 and achieving multiple effects.
