Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of lifting equipment technology, and more specifically, to a material lifting platform for building construction. Background Technology

[0002] In modern building construction, vertical material transportation is a crucial aspect of the construction process. Lifting platforms are designed to handle vertical transport, and they are categorized into wire rope traction and chain traction types, each with its own advantages and disadvantages. For example, wire rope traction platforms offer high strength, the ability to withstand significant tensile forces, and good elasticity and toughness, absorbing some energy under impact loads and reducing damage to the equipment. However, their rigidity is relatively low, making them prone to tensile deformation during traction. Chain traction platforms, on the other hand, offer high rigidity and wear resistance, capable of transmitting larger forces and less susceptible to tensile deformation. However, the chains have relatively poor toughness, making them prone to link breakage under impact loads.

[0003] In existing technologies, wire rope traction lifting platforms are typically used to handle heavy loads. These platforms control the lifting platform's ascent by the winding and unwinding of a winch. To simplify winch placement, the winch is usually placed horizontally on a support frame, and then the wire rope on the winch is verticalized via a first rotating pulley and connected to the lifting platform. However, in actual use, as the weight of the goods on the lifting platform increases, the pressure between the wire rope and the first rotating pulley increases, leading to increased friction. Prolonged operation under heavy loads significantly reduces the service life of the wire rope. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a material lifting platform for building construction, which solves the technical problem that the increased weight of goods on the existing lifting platform will cause accelerated wear of the wire rope.

[0005] According to one aspect, at least one embodiment of this disclosure provides a material lifting platform for building construction, including a support frame, a winch, a wire rope, and a lifting platform, comprising:

[0006] A number of fixing blocks are arranged at intervals on the wire rope;

[0007] The first rotating wheel is rotatably mounted on the bracket. The outer wall of the first rotating wheel has several slots for holding the fixing block. The first rotating wheel is configured such that one end of the wire rope is wound around the winch, and the other end is wound around the first rotating wheel and then fixedly connected to the lifting platform. When the wire rope is wound around the first rotating wheel, the fixing block enters the slot, and the fixing block pushes the first rotating wheel to rotate through the slot.

[0008] For example, in at least one embodiment of this disclosure, a material lifting platform for building construction further includes:

[0009] The first side baffle has two parts, which are respectively disposed on both sides of the first rotating wheel. The two first side baffles and the side wall of the first rotating wheel form a first limiting space. The first limiting space is used for the wire rope to be wound through. The two ends of the fixing block abut against the sides of the two first side baffles that are close to each other.

[0010] For example, in at least one embodiment of this disclosure, a material lifting platform for building construction includes a fixing block comprising:

[0011] The abutment block has an arc-shaped groove for abutting with the wire rope, and one end of the abutment block away from the arc-shaped groove abuts with a first side baffle.

[0012] Two abutting posts are provided on the abutting block. The abutting posts are located on both sides of the arc-shaped groove, and the abutting posts are used to abut against the other first side baffle.

[0013] A clamping plate is slidably disposed on the abutment post. The clamping plate is configured such that after sliding, it approaches or moves away from the arc-shaped groove. The clamping plate and the arc-shaped groove form a clamping space, which is used to clamp the wire rope.

[0014] For example, in a material lifting platform for building construction provided in at least one embodiment of this disclosure, the peripheral wall of the abutting column has external threads, and the fixing block further includes:

[0015] A tightening nut is threadedly engaged with the abutment post. The clamping plate is located between the tightening nut and the abutment block. The tightening nut is used to slide and push the clamping plate toward the abutment block.

[0016] For example, in at least one embodiment of this disclosure, a material lifting platform for building construction includes a winch comprising:

[0017] A rotation drive device is mounted on the bracket, and the rotation drive device has a drive end;

[0018] The second rotating wheel is rotatably mounted on the drive end, and the second rotating wheel is used to fix one end of the wire rope;

[0019] The second side baffle has two sections, which are respectively disposed at both ends of the second rotating wheel. The second side baffle and the outer wall of the second rotating wheel form a second limiting space. The second limiting space is used to wind the steel wire rope, and the fixing block is used to support the adjacent winding layers of the steel wire rope.

[0020] For example, in a material lifting platform for building construction provided in at least one embodiment of this disclosure, the fixed block has arc surfaces at both ends along the radial direction of the second rotating wheel, and the arc surfaces are respectively used to abut against the outer wall of the second rotating wheel and the winding layer of the adjacent wire rope.

[0021] For example, in a material lifting platform for building construction provided in at least one embodiment of this disclosure, a second side baffle has a plurality of first through holes, and the abutment block has a threaded hole. The abutment block is configured such that the abutment block disposed at the end of the wire rope is threadedly connected and fixed to the threaded hole by a bolt passing through one of the first through holes.

[0022] For example, in a material lifting platform for building construction provided in at least one embodiment of this disclosure, the first side baffle has a plurality of first process holes, and a second side baffle has a plurality of second process holes.

[0023] For example, in at least one embodiment of this disclosure, a material lifting platform for building construction further includes:

[0024] A pedal is rotatably mounted on the lifting platform, the axis of rotation of the pedal being perpendicular to the lifting direction of the lifting platform. The pedal is configured such that, after rotation, the other end away from the axis of rotation is used to attach to the building.

[0025] For example, in at least one embodiment of this disclosure, a material lifting platform for building construction further includes:

[0026] A plate is rotatably mounted on the lifting platform. The rotation axis of the plate is perpendicular to the rotation axis of the pedal. The plate is configured to prevent the pedal from rotating closer to the building after rotation.

[0027] The beneficial effects of the embodiments disclosed herein are as follows:

[0028] In this disclosure, a fixed block and a slot are used to rotate the first rotating wheel by friction. This is transformed into the fixed block pushing the slot to rotate the first rotating wheel, which effectively reduces the friction between the wire rope and the first rotating wheel, helps to extend the service life of the wire rope, and reduces the maintenance cost of the equipment and the frequency of replacing the wire rope.

[0045] like Figures 1-8As shown, this illustration depicts a material lifting platform for building construction according to an embodiment of this disclosure. The platform mainly comprises a support frame 100, a winch 200, a wire rope 300, a lifting platform 400, several fixing blocks 500, and a first rotating wheel 610 with a slot 611. The support frame 100 provides a stable support structure for the entire lifting platform. The winch 200 is installed at a suitable position on the support frame 100 and is used to wind and unwind the wire rope 300, thereby controlling the lifting and lowering of the lifting platform 400. Fixing blocks 500 are spaced apart on the wire rope 300, cooperating with the first rotating wheel 610, which is rotatably mounted on the support frame 100 and has a slot 611 on its outer wall, to solve the problem of wear on the wire rope 300 caused by increased cargo weight. The lifting platform 400 is used to carry materials for vertical transportation.

[0046] The support frame 100 is securely fixed to a solid concrete foundation with anchor bolts, ensuring the lifting platform will not sway during operation. The winch 200 is an electric winch, mainly composed of a motor, reducer, and drum. The motor provides power, and the reducer converts the high-speed rotation of the motor into low-speed, high-torque rotation of the drum, achieving the winding and unwinding of the wire rope 300. The drum is made of high-quality carbon steel with a special surface treatment to increase friction with the wire rope 300 and prevent slippage. The winch 200 is equipped with a braking device that can quickly brake the drum in case of power failure or emergency, ensuring the safety of the lifting platform 400.

[0047] Several fixing blocks 500 are spaced apart on the wire rope 300. The fixing blocks 500 are firmly fixed to the wire rope 300 by welding or bolting. The distance between adjacent fixing blocks 500 is the same as the spacing of the slots 611 on the first rotating wheel 610. The spacing between adjacent fixing blocks 500 on the wire rope 300 is generally between 200-500mm. The shape of the fixing block 500 is adapted to the slot 611, and it can be embedded in the slot 611 to achieve effective cooperation with the first rotating wheel 610.

[0048] Working Principle: When materials need to be lifted, the operator presses the "Up" button on the control panel. The motor of the winch 200 starts, driving the drum to rotate via the reducer. The drum begins to wind up the wire rope 300. As the wire rope 300 moves, the fixing blocks 500 on it sequentially approach the first rotating wheel 610. When the fixing block 500 reaches the first rotating wheel 610, it enters the slot 611. Due to the tension of the wire rope 300, the fixing block 500 pushes the first rotating wheel 610 to rotate through the slot 611, allowing the wire rope 300 to smoothly pass over the first rotating wheel 610, change direction, and wind onto the drum of the winch 200, thereby lifting the lifting platform 400. During the lifting process of the lifting platform 400, the guide wheels run along the guide rails on the support 100, ensuring the smooth lifting of the lifting platform 400.

[0049] When materials need to be lowered, the operator presses the descent button, causing the winch 200 motor to reverse, and the drum begins to unwind the wire rope 300. The lifting platform 400 descends under its own weight and the weight of the material. As the wire rope 300 moves, the fixing block 500 pushes the first rotating wheel 610 to rotate. The rotation of the first rotating wheel 610 allows the wire rope 300 to smoothly pass around it, allowing the end of the wire rope 300 connected to the lifting platform 400 to descend under the weight of the lifting platform 400. Similarly, the guide wheel runs along the guide rail, ensuring a smooth descent of the lifting platform 400.

[0050] By using the fixing block 500 in conjunction with the slot 611, the wire rope 300 drives the first rotating wheel 610 to rotate through friction. This is transformed into the fixing block 500 pushing the slot 611 to rotate the first rotating wheel 610, which effectively reduces the friction between the wire rope 300 and the first rotating wheel 610, helps to extend the service life of the wire rope 300, and reduces the maintenance cost of the equipment and the frequency of replacing the wire rope 300.

[0051] In some examples, a first side baffle 620 is also included. There are two first side baffles 620, which are respectively disposed on both sides of the first rotating wheel 610. The two first side baffles 620 and the side wall of the first rotating wheel 610 form a first limiting space 630. The first limiting space 630 is used for the wire rope 300 to be wound and passed through. The two ends of the fixing block 500 abut against the side of the two first side baffles 620 that are close to each other.

[0052] The first side baffle 620 is generally circular, with its inner diameter matching the outer diameter of the first rotating wheel 610, allowing it to fit snugly against both sides of the first rotating wheel 610. The outer diameter is determined based on the actual installation space and protection requirements, generally being 100-200mm larger than the outer diameter of the first rotating wheel 610 to provide sufficient limiting space. The first side baffle 620 is fixed to the bracket 100 by bolts or welding. If bolts are used, corresponding mounting holes are pre-machined on the first side baffle 620 and the bracket 100, and high-strength bolts are used for fastening. This method facilitates installation and disassembly, and makes it convenient for later inspection and maintenance of the first rotating wheel 610, wire rope 300, and fixing block 500. Welding provides a more robust connection and enhances the stability of the overall structure, but disassembly is more difficult during maintenance. During installation, it is necessary to ensure the coaxiality of the two first side baffles 620 and the first rotating wheel 610, ensuring the uniformity of the first limiting space 630 and preventing the wire rope 300 from shifting during winding.

[0053] The two first side baffles 620 and the side wall of the first rotating wheel 610 together form a first limiting space 630, providing a winding channel for the wire rope 300. The wire rope 300 winds and passes through this space, effectively preventing lateral deviation of the wire rope 300 during movement, ensuring that it always runs along the predetermined path, and improving the stability and reliability of the lifting platform operation.

[0054] The two ends of the fixing block 500 abut against the sides of the two first side baffles 620 that are close to each other. The distance between the two first side baffles 620 should be sufficient to ensure that the fixing block 500 can enter the first limiting space 630. The two first side baffles prevent the wire rope 300 from shifting within the first limiting space 630 by abutting against the fixing block 500.

[0055] In some examples, the fixing block 500 includes an abutment block 510 having an arcuate groove 511 for abutting against the wire rope 300. One end of the abutment block 510 away from the arcuate groove 511 abuts against a first side baffle 620. Two abutment posts 520 are provided on the abutment block 510, respectively located on both sides of the arcuate groove 511, and abutting posts 520 abut against the other first side baffle 620. A clamping plate 530 is slidably provided on the abutment post 520. The clamping plate 530 is configured such that after sliding, it approaches or moves away from the arcuate groove 511. The clamping plate 530 and the arcuate groove 511 form a clamping space 540 for clamping the wire rope 300.

[0056] The abutment block 510 is generally rectangular, with an arc-shaped groove 511 machined at one end to fit the wire rope 300. The curvature of the arc-shaped groove 511 is determined according to the diameter of the wire rope 300 to ensure a tight fit with the wire rope 300, increase the contact area, evenly distribute pressure, and avoid local stress concentration that could damage the wire rope 300. The end of the abutment block 510 away from the arc-shaped groove 511 is a flat surface, which abuts against one of the first side baffles 620. When the lifting platform is working, the abutment block 510 transmits part of the lateral force of the wire rope 300 to the first side baffle 620 through this flat surface, enhancing the stability of the fixing block 500 within the first limiting space 630.

[0057] The arc-shaped groove 511 can be increased at both ends along the length of the wire rope 300 to prevent the wire rope 300 from being damaged due to easy contact between the wire rope 300 and the arc-shaped groove 511 caused by the bending of the wire rope 300.

[0058] The abutment post 520 has a circular cross-sectional shape, which facilitates the sliding of the clamping plate 530 and evenly distributes stress under load. The length of the abutment post 520 is greater than the thickness of the clamping plate 530, ensuring that the clamping plate 530 has sufficient travel during sliding to accommodate wire ropes 300 of different diameters. It should be further noted that the different diameter wire ropes 300 referred to here are for abutment blocks 510 with arc grooves 511 of different diameters.

[0059] The clamping plate 530 is rectangular in shape. Anti-slip texture is provided on the side of the clamping plate 530 near the arc groove 511. When the clamping plate 530 slides close to the arc groove 511 to clamp the wire rope 300, the anti-slip texture can increase the friction between the clamping plate 530 and the wire rope 300, preventing the wire rope 300 from sliding in the clamping space 540.

[0060] The operator can manually slide the clamping plate 530 on the abutment column 520, adjusting the distance between the clamping plate 530 and the arc-shaped groove 511 according to the diameter of the wire rope 300 to form a suitable clamping space 540. Once the clamping plate 530 has slid to the appropriate position, the clamping space 540 can firmly clamp the wire rope 300, making the fixing block 500 and the wire rope 300 a single unit, moving synchronously during the operation of the lifting platform. This method simplifies the installation process of the fixing block 500 and allows for free adjustment of the spacing of the fixing blocks 500 according to actual needs.

[0061] The separate design of the clamping plate 530 and the abutment block 510 facilitates the overall assembly of the fixing block 500.

[0062] In some examples, the peripheral wall of the abutment post 520 has external threads, and the fixing block 500 also includes a tightening nut 550 that is threadedly engaged with the abutment post 520. The clamping plate 530 is located between the tightening nut 550 and the abutment block 510, and the tightening nut 550 is used to slide and push the clamping plate 530 toward the abutment block 510.

[0063] The tightening nut 550 engages with the external thread of the abutment post 520. The operator uses a tool to rotate the tightening nut 550, causing it to move along the external thread of the abutment post 520 towards the abutment block 510. As the tightening nut 550 advances, the clamping plate 530 experiences axial force between the tightening nut 550 and the abutment block 510, gradually moving closer to the arc-shaped groove 511, thereby clamping the wire rope 300. The tightening nut 550 not only controls the clamping degree of the clamping plate 530 on the wire rope 300, but also, due to the self-locking characteristic of its thread with the abutment post 520 during the operation of the lifting platform, effectively prevents the clamping plate 530 from loosening due to vibration or changes in the tension of the wire rope 300, ensuring a reliable connection between the fixing block 500 and the wire rope 300 at all times, and guaranteeing the safe and stable operation of the lifting platform. In actual operation, the operator can observe the distance between the clamping plate 530 and the abutment block 510 or use a torque wrench to control the tightening degree of the tightening nut 550 to achieve the appropriate clamping force. When it is necessary to replace the wire rope 300 or maintain the fixing block 500, simply rotate the tightening nut 550 in the opposite direction to move the clamping plate 530 away from the abutment block 510 and loosen the clamping of the wire rope 300.

[0064] In some examples, the winch 200 includes a rotation drive device 210 mounted on the bracket 100 and having a drive end; a second rotating wheel 220 rotatably mounted on the drive end and used to fix one end of the wire rope 300; two second side baffles 230 are respectively disposed at both ends of the second rotating wheel 220, and the outer walls of the second side baffles 230 and the second rotating wheel 220 form a second limiting space 240, which is used for winding the wire rope 300, and a fixing block 500 is used to support adjacent winding layers of the wire rope 300.

[0065] The rotary drive unit 210 is the core power component of the winch 200, mounted on the bracket 100, providing power output for the entire winch 200. It typically consists of a motor, a reducer, and a coupling. The motor, as the power source, can be selected based on the working requirements of the lifting platform, choosing a model with appropriate power and speed. For example, for a material lifting platform used in general building construction, a three-phase asynchronous motor with a power of 5-15kW might be selected to meet the lifting needs under different loads. The reducer serves to lower the motor's output speed and increase its output torque. Common reducer types include gear reducers and worm gear reducers, selected based on actual working conditions. The coupling connects the output shafts of the motor and the reducer, ensuring effective power transmission. Generally, a flexible coupling is used to compensate for the relative displacement between the two shafts and to buffer vibration and impact.

[0066] The second rotating wheel 220 has a cylindrical wheel body. One end of the wire rope 300 is fixed to the second rotating wheel 220. A common fixing method is to provide a fixing groove or fixing hole on the rim of the second rotating wheel 220. The end of the wire rope 300 is then fixed to these structures via a wire rope clamp, wedge joint, or direct winding. Regardless of the fixing method used, it is essential to ensure that the wire rope 300 is securely fixed and will not loosen or fall off during the operation of the winch 200. Two second side baffles 230 are respectively located at both ends of the second rotating wheel 220, forming a second limiting space 240 together with the outer wall of the second rotating wheel 220. The second limiting space 240 allows the wire rope 300 to wind smoothly within it while effectively restricting its lateral movement, ensuring that the wire rope 300 is neatly wound around the second rotating wheel 220.

[0067] The second limiting space provides an orderly winding space for the wire rope 300, preventing stacking or tangling during winding. When the winch 200 winds up and unwinds the wire rope 300, the wire rope 300 is arranged orderly along the outer wall of the second rotating wheel 220 within the second limiting space 240, improving the working efficiency and stability of the winch 200. Furthermore, the fixing block 500 also supports adjacent winding layers of the wire rope 300 during winding, ensuring the stability between adjacent winding layers.

[0068] In some examples, the fixing block 500 has arc surfaces at both ends along the radial direction of the second rotating wheel 220, which are respectively used to abut against the outer wall of the second rotating wheel 220 and the winding layer of the adjacent wire rope 300.

[0069] The fixing block 500 is designed with rounded surfaces at both ends along the radial direction of the second rotating wheel 220. The rounded surfaces can better fit the outer wall of the second rotating wheel 220 and avoid the right-angled edges from damaging the wound wire rope 300.

[0070] In some examples, a second side baffle 230 has a plurality of first through holes 231, and an abutment block 510 has a threaded hole 512. The abutment block 510 is configured such that the abutment block 510 located at the end of the wire rope 300 is threadedly connected to the threaded hole 512 by bolts passing through a first through hole 231.

[0071] During installation, align the abutment block 510 at the end of the wire rope 300 with the first through hole 231 on the second side baffle 230, and then screw a bolt through the first through hole 231 into the threaded hole 512 of the abutment block 510. By rotating the bolt, it is gradually tightened, thereby firmly fixing one end of the wire rope 300 to the second side baffle 230 through the abutment block 510, so that the winch 200 can stably complete the winding of the wire rope 300.

[0072] Fixing the abutment block 510 by means of bolts, threaded holes 512 and first through holes 231 not only helps to ensure the stability of the abutment block 510, but also simplifies the operation for operators and improves the ease of operation.

[0073] In some examples, the first side baffle 620 has a plurality of first process holes 621, and a second side baffle 230 has a plurality of second process holes 232.

[0074] The first process hole 621 and the second process hole on the first side baffle 620 and the second side baffle 230 not only improve the overall aesthetics of the first side baffle 620 and the second side baffle 230, but also reduce the load on the drive device due to the overall weight of the first side baffle and the second side baffle, thus saving energy.

[0075] In some examples, a footboard 700 is also included, which is rotatably mounted on the lifting platform 400. The axis of rotation of the footboard 700 is perpendicular to the lifting direction of the lifting platform 400. The footboard 700 is configured such that, after rotation, the other end of the footboard 700 away from the axis of rotation is used to attach to the building.

[0076] The platform 700 is rectangular in shape, with its length determined by the dimensions of the lifting platform 400 and actual usage requirements, typically between 1 and 2 meters, to ensure stable attachment to the building. Its width is generally 0.5 to 1 meter to facilitate the passage of personnel and materials.

[0077] During operation, once the lifting platform 400 has risen to a suitable height relative to the building's floor level, construction workers can manually rotate the footplate 700 to align it with the building's edge. For ease of operation, handles or pull rings can be installed on the footplate 700, allowing workers to rotate it by holding these grips. After material transport is complete or personnel have left, workers can return the footplate 700 to a position parallel to the lifting platform 400, enabling the platform to resume lifting operations.

[0078] In some examples, a clamping plate 800 is also included, which is rotatably mounted on the lifting platform 400. The rotation axis of the clamping plate 800 is perpendicular to the rotation axis of the pedal 700. The clamping plate 800 is configured to prevent the pedal 700 from rotating closer to the building after rotation. The pedal 800 can be fixed parallel to the side wall of the lifting platform 400 or laid flat on the bottom surface of the lifting platform 400.

[0079] When the pedal 800 is fixed parallel to the side wall of the lifting platform 400, in order to stably fix the pedal 700, a retaining plate 800 can be set on both sides of the fixed position of the pedal 700. After the retaining plate 800 rotates to a position that can block the rotation of the pedal 700, a limit plate prevents the retaining plate 800 from continuing to rotate, so that the retaining plate 800 can stay in the position that blocks the rotation of the pedal 700 by gravity.

[0080] When the pedal 800 is fixed in a flat position on the bottom surface of the lifting platform 400, the pallet 800 can prevent people or materials from being tripped on the pedal 800 and being lifted up, causing an accident.

[0081] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
