Description
Technical Field
[0001] This application relates to the technical field of construction hoisting, and in particular to a hoisting device for construction projects. Background Technology
[0002] Currently, hoisting equipment, as a core piece of equipment for material handling in construction engineering, is widely used in high-rise building, bridge construction, and steel structure installation. With the increasing scale and complexity of modern construction projects, higher demands are placed on the operational efficiency, safety performance, and environmental adaptability of hoisting equipment. Traditional hoisting equipment achieves load lifting and displacement through mechanical transmission and manual operation. However, modern construction is typically done in multi-level structures, using platforms to achieve level construction and tower cranes to suspend the gantry structure for the hoisting of some loose components.
[0003] In the prior art, lifting boxes used to support loose parts generally include a metal bucket made of iron material, with a sealed bottom wall forming a plane in contact with the ground, and multiple lifting lugs fixedly connected to the open side. The lifting lugs are used to suspend steel wire ropes, which are connected to the hook of the tower crane. During lifting operations, loose parts are generally placed in the metal bucket, and then the steel wire ropes are connected to the hook of the tower crane before the lifting operation is carried out.
[0004] However, when hoisting close to the building wall, the metal bucket is prone to swaying due to wind or during its descent. This swaying can cause the metal bucket to collide with the building wall, reducing safety. Summary of the Invention
[0005] To improve equipment safety, this application provides a hoisting device for construction engineering.
[0006] This application provides a hoisting device for construction engineering, which adopts the following technical solution:
[0007] A hoisting device for construction engineering, comprising:
[0008] The hoisting bucket forms a storage space for holding materials and has an opening on one side. The opening on one side is provided with an outwardly extending protective flange, and the outer surface of the protective flange is covered with an elastic buffer layer.
[0009] Lifting lugs are provided on the open side of the lifting bucket for suspending steel wire ropes. Multiple lugs are provided and distributed along the edge of the open side, and adjacent lugs are connected by flexible connecting strips to form a mesh protective structure.
[0010] Support wheels are provided on the side wall of the hoisting bucket, and multiple support wheels are provided and symmetrically distributed on both sides of the side wall of the hoisting bucket. They are used to contact the building wall and can rotate along the wall. Each support wheel is connected to the hoisting bucket through a telescopic connecting rod.
[0011] By adopting the above technical solution, after the material is loaded on the open side of the hoisting bucket, it is lifted and lowered by suspending a steel wire rope through the lifting lugs. During the hoisting process, the support wheels contact the building wall and roll along the wall surface. The elastic buffer layer of the protective flange provides initial cushioning when it approaches the wall, and the flexible connecting belt suppresses the swaying of the hoisting bucket. The protective flange and the elastic buffer layer directly absorb the impact of the collision, reducing the risk of hard contact between the hoisting bucket and the wall. The symmetrically distributed support wheels form double-sided support, reducing the swaying of the hoisting bucket and reducing large-scale contact and slippage between the hoisting bucket and the wall, thus reducing damage to the wall surface. The flexible connecting belt is used to limit the swaying of the lifting lugs and forms protection on the open side of the hoisting bucket, reducing the fall of smaller parts and improving safety.
[0012] Optionally, a pressure sensor is provided on the telescopic link.
[0013] By adopting the above technical solution, the pressure sensor monitors the contact pressure between the support wheel and the wall in real time, which facilitates the command of the tower crane to drive the hoisting bucket and reduces excessive force on the wall.
[0014] Optionally, the support wheel includes a wheel body and a wheel frame. The outer layer of the wheel body is covered with a rubber buffer layer, and the inner layer is embedded with a honeycomb shock-absorbing layer. The wheel frame is connected to the telescopic link through a ball joint, so that the support wheel can adaptively adjust the contact angle with the wall.
[0015] By adopting the above technical solution, when the support wheel contacts the wall, the ball joint structure allows the wheel to adaptively adjust its tilt angle; the rubber buffer layer and the honeycomb damping layer together attenuate vibration energy.
[0016] The ball joint connection allows the support wheel to fit against the wall at different inclination angles, avoiding local stress concentration; the honeycomb structure disperses impact force, and the rubber layer further absorbs high-frequency vibration, extending the life of the support wheel.
[0017] Optionally, the telescopic link is equipped with an adjustment component, which dynamically adjusts the extension length of the support wheel based on the contact pressure value fed back by the pressure sensor, so that the hoisting bucket maintains a preset distance from the wall.
[0018] By adopting the above technical solution, the pressure sensor detects the contact pressure between the support wheel and the wall; the adjustment component dynamically extends and retracts the connecting rod according to the pressure value to adjust the position of the support wheel; it maintains a constant distance between the hoisting bucket and the wall, which facilitates the construction of the wall surface by the workers loaded in the hoisting bucket, and also reduces the risk of scratches caused by the hoisting bucket being too close to the wall when transporting materials; it automatically maintains a safe distance to avoid collisions caused by human operation errors; and it only activates hydraulic adjustment when the pressure exceeds the limit, reducing energy waste.
[0019] Optionally, the end of the protective flange is provided with a detachable anti-collision strip, the anti-collision strip is filled with energy-absorbing material, and the outer surface is provided with a rolling ball, which can slide along the wall when in contact with the wall.
[0020] By adopting the above technical solutions, the anti-collision strip slides into contact with the wall through a rolling ball; the energy-absorbing material (such as foam metal) is compressed and deformed to absorb the collision energy; the anti-collision strip can be quickly disassembled and replaced after wear; rolling friction reduces contact resistance, and the energy-absorbing material further buffers the impact; the modular design simplifies the replacement process and reduces downtime.
[0021] Optionally, the end of the telescopic link away from the support wheel is rotatably mounted on the hoisting bucket, and the rotation direction is perpendicular to the hoisting bucket's lifting direction.
[0022] By adopting the above technical solution, when the hoisting bucket is raised or lowered, the telescopic connecting rod rotates around an axis perpendicular to the lifting direction; the support wheel automatically adjusts its angle according to the wall's orientation; when not in use, the support wheel can be folded to fit the hoisting bucket, reducing interference with the hoisting process; the support wheel can adapt to unevenness or changes in trajectory at corners; the degree of rotational freedom avoids rigid interference between the support wheel and the wall surface.
[0023] Optionally, a stop block is detachably connected to the hoisting bucket, and the stop block is located on the folded side of the telescopic link.
[0024] By adopting the above technical solution, when the telescopic link rotates to be perpendicular to the hoisting bucket, a stop block is installed on one side of the telescopic link to limit its rotation, reduce the rotation of the telescopic link, and ensure stable contact between the support wheel and the wall, thereby improving safety.
[0025] Optionally, a limiting groove is provided on the stop block, which can be used to limit the telescopic link when it is retracted.
[0026] By adopting the above technical solution, the telescopic link is embedded in the limiting groove of the stop when it is folded, and the limiting groove fixes the position of the link by physical buckle; mechanical limiting ensures the stability of the storage state and avoids shaking; the link can be fixed without additional tools, improving operation efficiency; at the same time, it can reduce the rotation of the telescopic link when it is not in use, reducing interference with hoisting.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. The flexible connecting strap is designed to limit the swaying of the lifting lugs and form a protective barrier on the opening side of the lifting bucket, reducing the fall of smaller parts and improving safety;
[0029] 2. After the telescopic link rotates to be perpendicular to the hoisting bucket, a stop block is installed on one side of the telescopic link to limit its rotation, reduce the rotation of the telescopic link, and ensure stable contact between the support wheel and the wall, thereby improving safety.
[0030] 3. No additional tools are required to fix the linkage, improving operational efficiency; at the same time, it can reduce the rotation of the telescopic linkage when it is not used, thus reducing interference with hoisting. Attached Figure Description

Detailed Implementation
[0037] The following combination Figures 1 to 5 This application will be described in further detail.
[0038] This embodiment discloses a hoisting device for construction engineering.
[0039] Reference Figure 1 The hoisting device of this application comprises a hoisting bucket 100, lifting lugs 200, and support wheels 300. The hoisting bucket 100 is used to hold materials or transport personnel. The lifting lugs 200 are installed on the hoisting bucket 100 to suspend steel wire ropes. The support wheels 300 are installed on the hoisting bucket 100 and are used to roll and connect with the wall when in contact with it. Materials are loaded from the open side of the hoisting bucket 100 and suspended by steel wire ropes through the lifting lugs 200; the support wheels 300 roll in contact with the building wall, dynamically adjusting the spacing and buffering collisions.
[0040] The hoisting bucket 100 is a box with an open top and a single-sided opening, with the opening side used for loading and unloading materials. A protective flange 110 is detachably connected to the hoisting bucket 100 by bolts. The protective flange 110 extends horizontally outward from the opening end, and its outer surface is covered with an elastic buffer layer (such as polyurethane rubber) with a thickness of 10-20mm, which is used to initially absorb collision energy.
[0041] There are four lifting lugs 200, which are evenly distributed along the side edge of the opening and are used to connect the steel wire rope. A flexible connecting strip is set between the lifting lugs 200. The flexible connecting strip is connected between two lifting lugs 200 by Kevlar fiber braided strip to form a protective net with a mesh size of 10cm×10cm.
[0042] Reference Figure 1 and Figure 2 Multiple support wheels 300 are provided and symmetrically arranged on both sides of the hoisting bucket 100. Each support wheel 300 includes a wheel body 310 and a wheel frame 320. The wheel body 310 is rotatably connected to the wheel frame 320. Each support wheel 300 is connected to the hoisting bucket 100 via a telescopic connecting rod 400. The outer layer of the wheel body 310 is a rubber buffer layer, and the inner layer is a rubber honeycomb shock-absorbing layer with thicknesses of 5mm and 15mm, respectively. The wheel frame 320 is connected to the telescopic connecting rod 400 via a ball joint, enabling adaptive adjustment of the support wheel 300's ±15° tilt angle. The telescopic connecting rod 400 includes a first set of rods 410 and a second set of rods 420. The first sleeve rod 410 and the second sleeve rod 420 are both square tubes. The first sleeve rod 410 is rotatably connected to the side wall of the hoisting bucket 100 through a hinge seat. The rotation direction of the first sleeve rod 410 is perpendicular to the lifting direction of the hoisting bucket 100. A sliding groove is provided in the first sleeve rod 410. The second sleeve rod 420 is slidably connected in the sliding groove and connected to a ball joint. The adjusting component 430 can be a spring 431. The spring 431 is set at the bottom of the sliding groove. The other end of the spring 431 is connected to the second sleeve rod 420. The spring 431 pushes the second sleeve rod 420 away from the hoisting bucket 100.
[0043] In other embodiments, the adjusting assembly 430 further includes an electric push rod 432, which is a threaded electric push rod 432. The electric push rod 432 is disposed within the first sleeve rod 410, and the piston rod is connected to the second sleeve rod 420. In other embodiments, it can also be used in conjunction with a spring 431. When used in conjunction, it also includes an adjusting plate, which slides within a sliding groove. The spring 431 is disposed on the adjusting plate, and the piston rod of the electric push rod 432 is connected to the adjusting plate.
[0044] Pressure sensors are installed in the first set of rods 410 and the second set of rods 420. The pressure sensors are used to measure the pressure exerted by the wall on the hoisting bucket 100.
[0045] In other embodiments, the pressure sensor can be electrically connected to the electric push rod 432 to dynamically adjust the length of the telescopic link 400 based on the contact pressure (threshold set to 50-200N) fed back by the pressure sensor, thereby maintaining the distance between the hoisting bucket 100 and the wall.
[0046] The protective flange 110 has a detachable anti-collision strip 120 at its end, which is filled with foam aluminum energy-absorbing material and has a ceramic rolling ball embedded on its outer surface with a diameter of 20mm.
[0047] Reference Figure 3 , Figure 4 and Figure 5 To facilitate the fixing of the telescopic link 400, a slot 130 is provided on the hoisting bucket 100. The slot 130 is located on the inner side of the telescopic link 400 in the folding direction, near the middle of the hoisting bucket 100. A stop block 500 is inserted into the slot 130 and abuts against the rotating side of the telescopic link 400 to limit the folding of the telescopic link 400. A limiting groove 510 is provided on the stop block 500. The opening width of the limiting groove 510 is adapted to the outer side of the first sleeve rod 410. When the first sleeve rod 410 is folded, the stop block 500 can be inserted into the slot 130, and the limiting groove 510 is engaged with the first sleeve rod 410 to fix the first sleeve rod 410 in the retracted state.
[0048] To improve the installation stability of the stop block 500, an anti-detachment groove 140 is provided on the side wall of the limiting groove 510. The anti-detachment groove 140 is provided along the length direction of the first sleeve rod 410 after it is folded. An anti-detachment block 600 is provided on the stop block 500. When the end of the stop block 500 is 5cm away from the bottom of the slot 130, the anti-detachment block 600 corresponds to the anti-detachment groove 140 and can slide into the anti-detachment groove 140. The anti-detachment groove 140 is used to limit the anti-detachment block 600 from moving away from the hoisting bucket 100.
[0049] Load concrete or other materials or transport personnel into the side hoisting bucket 100 from the opening, connect the tower crane wire rope to the lifting lug 200; install the anti-collision strip 120, and check whether the telescopic linkage 400 is in the deployed working state.
[0050] The tower crane lifts the hoisting bucket 100, and the support wheels 300 contact the wall and roll. The electric push rod 432 automatically adjusts the spacing according to the pressure feedback. If the hoisting bucket 100 is deflected due to a sudden lateral wind, the elastic buffer layer of the protective flange 110 and the anti-collision strip 120 absorb the collision energy step by step. After the operation is completed, the stop block 500 is removed, the support wheels 300 are manually folded back to fit against the side wall of the hoisting bucket 100, and then the stop block 500 is inserted into the slot 130 and slid to make the anti-detachment block 600 move into the anti-detachment groove 140.
[0051] The elastic buffer layer, hydraulic spacing adjustment, and anti-collision strip 120 form a three-level buffer, reducing the wall scratch rate by more than 70%; the rolling ball reduces the contact friction coefficient from 0.6 to 0.2, reducing power loss; the support wheel 300 adaptive adjustment combined with the counterweight dynamic balance controls the swing amplitude of the hoisting bucket 100 within ±5°; the flexible connecting belt reduces the risk of material falling by 90%.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
