Description

Technical Field

[0001] This utility model belongs to the field of building construction lifting technology, and specifically relates to a building construction lifting device. Background Technology

[0002] Construction hoisting devices use a power system to drive the drum / pulley to rotate, and use wire ropes or chains to transmit power to achieve vertical lifting and lowering of the cage. In construction, the hoisting cage is a key piece of equipment for vertical material transportation, and it often needs to be transported by handcarts loaded with materials. However, the base of existing hoisting cages is mostly a flat structure, lacking a dedicated positioning device for handcarts. As a result, handcarts can only be supported manually or simply tied with ropes during transportation. This not only makes them prone to lateral sliding, tilting, or even tipping over due to inertia when the cage starts, brakes, or is affected by wind, causing material spillage and posing a risk of falling objects from height, but also makes it impossible to use a uniform structure to fix the handcarts due to differences in wheel spacing and diameter. This requires repeated adjustments to the fixing method, which is cumbersome and inefficient. At the same time, the hard contact and collision between the handcart and the cage base and guardrails can easily cause wheel deformation and wear on the inner wall of the cage, increasing equipment maintenance costs. In addition, the shift in the center of gravity of the cage caused by the swaying of the handcart will also accelerate the wear and tear on the hoist guide rails and wire ropes over long-term use, posing significant safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a building construction lifting device to solve the problem mentioned in the background art that the building construction lifting cage does not have a positioning structure for the material handcart.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a building construction lifting device, comprising a lifting cage, a base plate fixed to the bottom of the lifting cage, a lifting wheel fixed to the top of the lifting cage, a rotatable and fixed protective plate provided on both the surface and back of the lifting cage, a material trolley positioning component provided at the top of the base plate, the material trolley positioning component comprising fixed seats symmetrically arranged at the top of the base plate, and an embedded arc groove provided inside the fixed seats.

[0005] Preferably, one end of the fixed base extends and is fixed with an outwardly expanding inclined push plate, the opening of which is conical.

[0006] Preferably, the top of the base plate is provided with a sliding groove, and the bottom of the fixing seat is fixed with a slider embedded in the sliding groove, and the slider is slidably connected to the sliding groove.

[0007] Preferably, a fixing plate is fixed to one side of the fixing base, a locking hole is provided through the top of the fixing plate, a locking rod is provided at the top of the fixing plate and screwed into the locking hole, and the end of the locking rod is pressed and fitted against the top of the base plate.

[0008] Preferably, the other end of the fixing base is provided with a push-out plate, and the cross-section of the push-out plate is a trapezoidal structure.

[0009] Preferably, the inner wall of the fixed base is symmetrically provided with rotating grooves on both sides, and rotating blocks adapted to the rotating grooves are symmetrically fixed on both sides of the push plate. The rotating blocks are rotatably connected to the rotating grooves, and a torsion spring is provided in the end of the rotating block.

[0010] Preferably, both the groove and the slider have T-shaped cross-sections, and the cross-section of the slider is proportionally smaller than that of the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention reliably secures the wheels of a handcart using a material trolley positioning component. An embedded arc-shaped groove conforms to the wheel's contour, and together with a fixing seat, it prevents the handcart from sliding, tilting, or tipping over, avoiding material spillage and the risk of falling objects from heights. The fixing seat is slidably connected to a slide rail via a slider, allowing for adjustable spacing according to the handcart's specifications. An outwardly expanding inclined push plate guides the wheels in quickly, offering strong adaptability and convenient operation. The push-out plate, in conjunction with a torsion spring, reduces rigid impact during push-out, while the T-shaped slide rail and slider ensure stable adjustment and reduce equipment wear. A locking rod quickly locks the position, improving loading efficiency, reducing overall center of gravity shift, and extending the elevator's lifespan, making it suitable for high-frequency material transportation scenarios.

[0019] 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.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a construction lifting device, including a lifting cage 1, a base plate 2 fixed to the bottom of the lifting cage 1, a lifting wheel 3 fixed to the top of the lifting cage 1, and rotatable and fixed protective plates on both the surface and back of the lifting cage 1. A material cart positioning component is provided at the top of the base plate 2. The material cart positioning component includes fixed seats 100 symmetrically arranged at the top of the base plate 2. The fixed seats 100 have an embedded arc groove 101 inside. The symmetrically arranged fixed seats 100 conform to the contour of the handcart wheel through the embedded arc groove 101, which can form a wrap-around limit on the wheel. With the clamping action of the fixed seats on both sides, the rolling of the wheel can be directly restricted, avoiding the handcart from sliding laterally, tilting or overturning when the cage is running (starting, braking or affected by wind), thus preventing the risk of material spillage and falling objects from height from the root, while ensuring that the handcart and the cage are relatively fixed, reducing the wear and tear on the lifting machine caused by the center of gravity shift.

[0021] In this embodiment, preferably, one end of the fixed base 100 is extended and fixed with an outwardly expanding inclined push plate 200. The opening of the inclined push plate 200 is conical. The conical opening design of the inclined push plate 200 can guide the trolley wheels to automatically slide into the fixed base along the inclined surface without the need for precise manual alignment, reducing the difficulty of operation when pushing in and improving loading efficiency. At the same time, the conical structure can buffer the contact impact force between the wheels and the fixed base, reducing equipment wear caused by hard collisions (such as wheel deformation and damage to the edge of the fixed base).

[0022] In this embodiment, preferably, a groove 300 is provided at the top of the base plate 2, and a slider 301 embedded in the groove 300 is fixed at the bottom of the fixed seat 100. The slider 301 is slidably connected to the groove 300. The groove 300 on the base plate 2 is slidably connected to the slider 301 at the bottom of the fixed seat 100, so that the fixed seat 100 can flexibly adjust the spacing along the groove 300 to adapt to different specifications of handcarts (such as wheel spacing of 40-80cm), solving the problem of poor adaptability of traditional fixed structures. The sliding connection method is easy to operate and can be adjusted without disassembly, improving the versatility of the device.

[0023] In this embodiment, preferably, a fixing plate 400 is fixed to one side of the fixing base 100. A locking hole 401 is provided through the top of the fixing plate 400. A locking rod 402 is provided at the top of the fixing plate 400 and is screwed into the locking hole 401. The end of the locking rod 402 is pressed and fitted against the top of the base plate 2. After the locking rod 402 on the fixing plate 400 is screwed into the locking hole 401, the end is pressed and fitted against the base plate, which can quickly lock the adjusted position of the fixing base 100, prevent the fixing base 100 from shifting due to vibration during transportation, and ensure the reliability of the fixing. Loosening the locking rod 402 can release the limit, which is convenient to operate and can complete the switching between fixing and adjustment without tools, thus improving work efficiency.

[0024] In this embodiment, preferably, the other end of the fixed seat 100 is provided with a push-out plate 500. The cross-section of the push-out plate 500 is trapezoidal. When the wheel of the push-out plate is pushed out, it can form a transition slope to guide the wheel to roll out of the fixed seat smoothly, avoiding wheel jamming or hard collision with the end of the fixed seat. The trapezoidal structure can also enhance the load-bearing capacity of the push-out plate, adapt to the push-out requirements of heavy-duty handcarts, and reduce the risk of structural deformation.

[0025] In this embodiment, preferably, the inner wall of the fixed base 100 is symmetrically provided with rotating grooves 600 on both sides, and the two sides of the push plate 500 are symmetrically fixed with rotating blocks 601 adapted to the rotating grooves 600. The rotating blocks 601 are rotatably connected to the rotating grooves 600, and a torsion spring 602 is provided in the end of the rotating blocks 601. The rotatable connection between the rotating blocks 601 and the rotating grooves 600 allows the push plate to be flexibly flipped. With the elastic reset function of the torsion spring 602, the push plate 500 can automatically spring up and reset after the wheel is pushed out, and can return to the initial state without manual intervention, which is convenient for the next use. The buffering effect of the torsion spring 602 can reduce the impact noise and wear when the push plate 500 flips, and extend the service life of the device.

[0026] In this embodiment, preferably, both the slide groove 300 and the slider 301 have T-shaped cross-sections. The cross-section of the slider 301 is proportionally smaller than that of the slide groove 300. The T-shaped cross-section design ensures that the slider 301 will not fall off when sliding in the slide groove 300, improving the stability of the adjustment process of the fixed seat 100 and avoiding tilting or jamming of the fixed seat 100 due to the offset of the slider 301. The slider 301 is smaller than the slide groove 300, leaving a certain gap to reduce sliding friction resistance, making the spacing adjustment smoother and reducing the operating intensity.

[0027] The working principle and usage process of this utility model are as follows: When a handcart containing materials needs to be pushed into the lifting cage 1 for lifting, first rotate and open the protective plate at the entrance of the lifting cage 1. Then, adjust the distance between the two fixed seats 100 according to the size of the handcart. At this time, loosen the locking rod 402 at the top of the fixed plate 400 so that the end of the locking rod 402 separates from the top of the bottom plate 2 and is screwed into the locking hole 401, which can release the limitation on the fixed seat 100. Then, push the fixed seat 100 so that it drives the slider 301 to slide inside the slide groove 300. Once the distance between the two fixed seats 100 is adjusted to match the position of the handcart wheel, tighten the locking rod 402 so that it rotates from the inside of the locking hole 401 and presses against the top of the base plate 2, thus limiting the position of the fixed seat 100. Then, push the handcart into the lifting cage 1 so that the handcart wheel enters the fixed seat 100 through the inclined push plate 200 and is embedded in the inner arc groove 101 for limiting. At this time, the protective plate at the entrance of the lifting cage 1 can be rotated and closed, and then the lifting cage 1 can be lifted upward by the hoist. During the lifting process, the wheels are limited by the embedded arc-shaped groove 101, and the wheels are clamped on both sides by the fixing seat 100, which can fix the handcart and prevent it from sliding or tilting laterally due to inertia. This fundamentally prevents the handcart from colliding with the cage railing, tipping over, or causing the risk of falling objects from height due to spilled materials such as concrete or bricks. When the lifting cage 1 moves to the corresponding height of the building floor, the protective plate at the exit of the lifting cage 1 is rotated open, and then the handcart is pushed forcefully, so that the wheels of the handcart roll out from inside the embedded arc-shaped groove 101. The wheel rolls against the ejector plate 500, causing the ejector plate 500 to rotate out from the other end of the fixed seat 100 and fit against the top of the base plate 2. At the same time, the rotating block 601 rotates inside the rotating groove 600, compressing the torsion spring 602 and causing it to deform. This allows the wheel to be ejected from the outlet of the fixed seat 100 through the ejector plate 500. Then, the handcart enters the interior of the high-rise building from the outlet of the lifting cage 1. At this time, the rotating block 601 rotates and resets inside the rotating groove 600 under the action of the torsion spring 602. At the same time, the ejector plate 500 resets and bounces up, locking into the other end of the inner wall of the fixed seat 100 for closure.
