Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a lightweight material hoisting device. Background Technology

[0002] In modern industrial production and logistics, hoisting operations are indispensable. Traditional large-scale hoisting equipment, such as gantry cranes and tower cranes, demonstrate significant advantages in transporting heavy goods due to their powerful lifting capacity. However, the limitations of this type of large equipment are also quite obvious; they are bulky and occupy a lot of space, requiring substantial manpower, material resources, and time costs for installation, commissioning, dismantling, and relocation.

[0003] However, lifting is often required during the handling of light materials. When faced with the need to handle light materials, large hoisting equipment takes a long time in preparation, hoisting operations, and finishing up, which is extremely inefficient given the high frequency and small batch characteristics of handling light materials.

[0004] Existing lightweight lifting devices, besides having heavy components that are inconvenient to move, also require connection points above the work platform for fixing and supporting the lifting equipment to provide stable support. These connection points are typically building structural components, such as steel beams or concrete beams, or specially designed embedded parts for auxiliary lifting. When there are no fixed support points above the platform, it becomes impossible to lift materials to the target platform, leading to work difficulties and affecting overall work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight material hoisting device to alleviate the technical problems of existing technologies, such as the large weight of its own components and the need to set fixed support points above the work platform.

[0006] The present invention provides a lightweight material hoisting device, comprising: a lever arm, a first pulley, a second pulley, a winch, a wire rope, a slide assembly, a rotating assembly, and a support assembly;

[0007] One end of the lever arm is fixed to a first pulley, and the other end of the lever arm is fixed to a second pulley. A winch is arranged above the second pulley, and a wire rope is wound on the winch. The end of the wire rope away from the winch passes through the second pulley and the first pulley in sequence and is connected to the light material. The wire rope is used to drive the light material to reciprocate in the vertical direction.

[0008] The slide cylinder assembly is sleeved on the outer wall of the lever arm. The bottom end of the slide cylinder assembly is detachably connected to the rotating assembly, and the bottom end of the rotating assembly is fixedly connected to the support assembly.

[0009] Furthermore, the slide assembly includes a sleeve body, a connecting lug, and fastening bolts;

[0010] The sleeve body is fitted onto the outer wall of the lever arm. A connecting lug is fixed to any end of the sleeve body. The connecting lug has a first through hole for detachable connection with the rotating component. Threaded holes are also symmetrically formed on the surface of the sleeve body. The threaded holes are threadedly connected to fastening bolts, and the end of the fastening bolt abuts against the outer wall of the lever arm.

[0011] Furthermore, the rotating assembly includes an inner rod, an outer rod, rollers, and a sliding platform;

[0012] The bottom end of the inner rod is inserted into the outer rod. The upper part of the inner rod has a second through hole that matches the first through hole. The second through hole is connected to the first through hole through a pin. A roller is set in the middle of the inner rod. A sliding platform is welded along the outer periphery at the top of the outer rod. The bottom of the roller abuts against the sliding platform. The bottom of the outer rod is fixedly connected to the support assembly.

[0013] Furthermore, the support components include a triangular frame and pulleys;

[0014] The triangular frame moves via pulleys at its bottom, and its top is fixed to the outer rod.

[0015] Furthermore, the support assembly includes a fixed rod and a frustum fixed to the bottom end of the fixed rod;

[0016] The fixing rod is cylindrical, and its top end is fixedly connected to the outer rod.

[0017] Furthermore, the support assembly also includes a support frame disposed at the end of the lever arm; the support frame is used to support the lever arm.

[0018] Furthermore, several positioning rings are evenly spaced on the outer wall of the lever arm, and the steel wire rope passes through the positioning rings.

[0019] Furthermore, the inclination angle between the first pulley and the lever arm is 30° to 45°; the second pulley is perpendicular to the lever arm.

[0020] Furthermore, a counterweight basket is installed at the end of the lever arm that is away from the lightweight material.

[0021] Furthermore, a handle is fixed to the end of the lever arm.

[0022] Beneficial effects:

[0023] This utility model provides a lightweight material lifting device. One end of a lever arm is fixedly connected to a first pulley, and the other end is fixedly connected to a second pulley. A winch is positioned above the second pulley, and a steel wire rope is wound around the winch. The end of the steel wire rope away from the winch passes sequentially through the second pulley and the first pulley, connecting to the lightweight material. The steel wire rope is used to drive the lightweight material to reciprocate vertically. By cooperating with the winch and the two pulleys, and utilizing the pulley system principle, the pulling force required to lift the lightweight material can be effectively reduced, making operation easier. The traction action of the winch is used to achieve the purpose of lifting operations on a platform without a fixed upper point, thereby completing the transportation of the required materials on a platform without a fixed upper point.

[0024] The sliding cylinder assembly is sleeved on the outer wall of the lever arm. The bottom end of the sliding cylinder assembly is detachably connected to the rotating assembly, and the bottom end of the rotating assembly is fixedly connected to the support assembly. The sliding cylinder assembly and the rotating assembly together form a universal structure that can adjust the rotation direction, allowing for easy torque adjustment and convenient control during hoisting operations.

[0025] This utility model is simple to manufacture and has a low manufacturing cost. It is suitable for hoisting materials weighing up to 1000kg. It is small in size, easy to carry, and easy to assemble and disassemble. It is convenient for on-site use to quickly complete the hoisting and handling of materials on platforms without fixed points above. Attached Figure Description

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] like Figure 1 As shown, this utility model provides a lightweight material hoisting device, including: lever arm 1, first pulley 2, second pulley 3, winch 4, wire rope 5, slide assembly 6, rotating assembly 7, and support assembly 8;

[0041] One end of lever arm 1 is fixedly connected to a first pulley 2, and the other end of lever arm 1 is fixedly connected to a second pulley 3. Winch 4 is arranged above the second pulley 3. Steel wire rope 5 is wound on winch 4. The end of steel wire rope 5 away from winch 4 passes through the second pulley 3 and the first pulley 2 in sequence and is connected to the light material. Steel wire rope 5 is used to drive the light material to reciprocate in the vertical direction.

[0042] The slide cylinder assembly 6 is sleeved on the outer wall of the lever arm 1. The bottom end of the slide cylinder assembly 6 is detachably connected to the rotating assembly 7, and the bottom end of the rotating assembly 7 is fixedly connected to the support assembly 8.

[0043] Specifically, lever arm 1 is made of thick-walled seamless steel pipe, with a length of approximately 6 meters. This length of steel pipe effectively prevents deformation due to insufficient strength. If working on an open platform, it can be lengthened or thickened according to the actual situation. At both ends of lever arm 1, a first pulley 2 and a second pulley 3 are installed respectively, and both pulleys are fixed pulleys. Fixed pulleys can change the direction of force, making the tension direction of the wire rope more consistent with the actual operational requirements.

[0044] Above the second pulley 3, a bracket is formed by welding iron plates, and the winch 4 is mounted on this bracket. To protect the winch 4 from rainwater corrosion, a rain cover is added above it. A steel wire rope 5 is wound around the winch 4, passing sequentially around the second pulley 3 and the first pulley 2. At the end of the steel wire rope 5, a hook is provided for suspending lightweight materials; for some specially shaped lightweight materials, the steel wire rope 5 can also be directly wound around the material, and the winch 4 can be used to pull the lightweight material to reciprocate in the vertical direction, thereby achieving longitudinal displacement during hoisting. This utility model can complete the material handling task even when there are no steel beams, concrete beams, or specially embedded hoisting parts above the platform, i.e., when there is no fixed point on the upper platform.

[0045] A sliding cylinder assembly 6 is fitted onto the outer wall of the lever arm 1, near the front end, at a position of 1 / 4 to 1 / 5. The sliding cylinder assembly 6 can slide flexibly left and right on the lever arm 1. By adjusting its position, the torque can be changed according to the weight of the material, ensuring the stability and safety of the lifting operation. The bottom end of the sliding cylinder assembly 6 is detachably connected to the rotating assembly 7. The two are pre-drilled with matching concentric holes, and a pin is inserted into the hole to achieve the connection. This connection method facilitates the movement of the sliding cylinder assembly 6 according to actual needs during operation and also facilitates disassembly during equipment transportation or storage. When the rotating assembly 7 rotates left and right, it can drive the lever arm 1 to rotate as well, and in conjunction with the traction of the winch 4, achieve the ideal lifting effect.

[0046] The bottom of the rotating component 7 is welded integrally with the support component 8. The support component 8 comes in two types. For temporary work scenarios, a triangular support component can be selected, with casters equipped with brakes at the feet for easy movement and quick deployment. When fabricating this triangular support bracket, angle iron of 10mm x 10mm or larger, or channel steel of 10mm or larger, must be used to ensure structural strength. For platforms used in long-term fixed positions, a fixed bracket is used, which must be made of thick-walled seamless steel pipe of at least DN80. Before hoisting operations, the support bracket must be securely connected to the fixed point using ropes. Especially for heavy materials, it is crucial to ensure the stability of the support bracket to prevent equipment swaying due to excessive weight during hoisting, thus ensuring operational safety.

[0047] In embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the slide assembly 6 includes a sleeve body 601, a connecting lug 602, and a fastening bolt 604;

[0048] The sleeve body 601 is sleeved on the outer wall of the lever arm 1. A connecting ear 602 is fixedly connected to any end of the sleeve body 601. The connecting ear 602 has a first through hole 603, which is used for detachable connection with the rotating component 7. The surface of the sleeve body 601 is also symmetrically provided with threaded holes, which are threadedly connected to the fastening bolt 604. The end of the fastening bolt 604 abuts against the outer wall of the lever arm 1.

[0049] The rotating assembly 7 includes an inner rod 701, an outer rod 702, a roller 704, and a sliding platform 705;

[0050] The bottom end of the inner rod 701 is inserted into the outer rod 702. The upper part of the inner rod 701 is provided with a second through hole 703 that matches the first through hole 603. The second through hole 703 is connected to the first through hole 603 by a pin. A roller 704 is provided in the middle of the inner rod 701. A sliding platform 705 is welded along the outer periphery at the top of the outer rod 702. The bottom of the roller 704 abuts against the sliding platform 705. The bottom of the outer rod 702 is fixedly connected to the support assembly 8.

[0051] Specifically, the sleeve body 601 is cylindrical and fits onto the outer wall of the lever arm 1, with its installation position located at the front end of the lever arm 1. It can slide left and right on the lever arm 1, adjusting the position of the connected rotating component 7 by changing its own position. This allows for torque adjustment based on the weight of the material, ensuring the stability and safety of the entire lifting operation.

[0052] A cylindrical connecting lug 602 is welded to either end of the sleeve body 601, and a first through hole 603 is provided on the connecting lug 602. The first through hole 603 is used to match a concentric hole on the rotating component 7, and then a pin is inserted into the hole to achieve the connection between the two.

[0053] To prevent the sleeve body 601 from slipping during operation, threaded holes are symmetrically opened on the surface of the sleeve body 601. By connecting with the fastening bolt 604, the end of the fastening bolt 604 is pressed tightly against the outer wall of the lever arm 1, thereby locking the sleeve body 601 onto the lever arm 1.

[0054] The inner rod 701 in the rotating assembly 7 is fork-shaped. Two second through holes 703, matching the first through hole 603 of the connecting lug 602, are opened on both sides of the upper U-shaped portion of the inner rod 701. A pin is inserted to detachably connect the two second through holes 703 to the first through hole 603. The bottom of the outer rod 702 is welded to the support assembly 8.

[0055] The bottom columnar part of the inner rod 701 is inserted into the outer rod 702. Two iron plates clamp the roller 704 at the bottom of the U-shaped section of the inner rod 701. A rotating shaft is inserted into the center of the roller 704, and sliding bearings are fitted on both sides to hold the roller 704. The bottom of the roller 704 abuts against the sliding platform 705, which is welded to the outer periphery of the top of the outer rod 702 in a disc shape. The rotating assembly 7 allows the inner rod 701 to rotate 360° omnidirectionally based on the outer rod 702, making it suitable for different positions and ultimately meeting the lifting needs of lightweight materials.

[0056] As one embodiment of this utility model, such as Figure 4 As shown, the support assembly 8 includes a triangular frame 801 and pulleys 802;

[0057] The triangular frame 801 moves via the pulley 802 at its bottom end, and the top of the triangular frame 801 is fixedly connected to the outer rod 702.

[0058] Specifically, in temporary work scenarios, the support component 8 is triangular. The bottom of the triangular frame 801 is equipped with pulleys 802, allowing for quick movement to the work position and setup. For stability and safety during operation, the materials used to manufacture the triangular support bracket are angle iron with a specification of 10mm × 10mm or larger, or channel steel with a thickness of 10mm or larger, ensuring sufficient structural strength to provide reliable support for the entire hoisting operation.

[0059] As another embodiment of this utility model, such as Figure 5 As shown, the support assembly 8 includes a fixed rod 803 and a frustum 804 fixed to the bottom end of the fixed rod 803;

[0060] The fixing rod 803 is cylindrical, and the top of the fixing rod 803 is fixedly connected to the outer rod 702.

[0061] Specifically, for platforms used in a fixed position for extended periods, a fixing rod 803 is used. The fixing rod 803 is made of thick-walled seamless steel pipe with a diameter of at least DN80. For added stability, a frustum 804 is also arranged at the bottom of the fixing rod 803 to increase the contact area with the ground.

[0062] It should be noted that, regardless of the type of support component used, before hoisting operations, the support frame must be securely connected to the fixing point using ropes (e.g., Figure 4 (Diagonal lines and trapezoids in the image), especially for heavier materials, ensure the stability of the support frame to prevent the equipment from shaking due to excessive weight during hoisting and ensure operational safety.

[0063] In an embodiment of the present invention, the support assembly 8 further includes a support frame 805 disposed at the end of the lever arm 1; the support frame 805 is used to support the lever arm 1.

[0064] Specifically, the support frame 805 can be triangular or T-shaped. The support frame 805 is made of small iron pipes and its weight can be manually moved to support the lifting boom 1 during operation or standby.

[0065] In an embodiment of this utility model, a plurality of positioning rings 101 are evenly spaced on the outer wall of the lever arm 1, and the steel wire rope 5 passes through the positioning rings 101.

[0066] The inclination angle between the first pulley 2 and the lever arm 1 is 30° to 45°; the second pulley 3 is perpendicular to the lever arm 1.

[0067] A counterweight basket 102 is provided at the end of the lever arm 1 that is away from the light materials.

[0068] A handle 103 is fixedly attached to the end of lever arm 1.

[0069] Specifically, several positioning rings 101 are evenly and equidistantly distributed on the outer wall of the lever arm 1, through which the wire rope 5 passes. The positioning rings 101 effectively prevent the wire rope 5 from detaching from the lever arm 1 when the winch 4 starts, ensuring the stability of the wire rope 5's movement trajectory and providing a guarantee for the safety of the hoisting operation.

[0070] Specifically, the first pulley 2 is installed at an angle between its inclination and that of the lever arm 1, maintained between 30° and 45°, while the second pulley 3 is perpendicular to the lever arm 1. This angle setting optimizes the force and direction of movement of the wire rope 5. By utilizing the characteristic of the fixed pulley to change the direction of force, operators can more easily control the winch 4, smoothly lifting light materials vertically and improving the operability of the lifting operation.

[0071] Specifically, a counterweight basket 102 is provided at the end of the lever arm 1 that is away from the light materials. Its main function is to adjust the torque balance of the entire device by adding or removing weights in the counterweight basket 102 according to the weight of the hoisted object, so as to prevent the device from overturning due to torque imbalance during hoisting and ensure the stability of hoisting operations.

[0072] A handle 103 is fixed to the end of the lever arm 1 to facilitate control of the lifting lever arm 1 during operation.

[0073] Based on the above embodiments, the working process of the lightweight material hoisting device provided by this utility model is as follows: select a suitable support component 8 according to the operation scenario. Taking a temporary operation scenario as an example, select a triangular frame 801 with pulleys 802, move it to the operation position, use ropes to firmly connect the support bracket to the fixed point, and brake and lock the pulleys 802.

[0074] Adjust the position of the slide assembly 6 on the lever arm 1 according to the weight, generally ensuring that the length of the lever arm 1 at the front end of the slide assembly 6 is at least 1.5m; fix it to the lever arm 1 using the fastening bolts 604 on the slide assembly 6. At the same time, add or remove weights in the counterweight basket 102 according to the torque ratio to adjust the counterweight, following the principle of choosing the larger rather than the smaller counterweight.

[0075] Rotate the lifting boom 1 out of the platform and suspend it in the air. Lower the wire rope 5 and operate the winch 4 to pull the wire rope 5. The wire rope 5 will lift the light material vertically until the object is lifted to a position above the platform.

[0076] The rotating component 7 drives the entire lever arm 1 to rotate, causing lightweight materials to fall onto the platform, thus completing the hoisting process. The hoisting device does not require an upper fixing point and has a simple structure, making it easy to move and use.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
