Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, specifically relating to a multi-dimensional adjustable hoisting structure. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In existing technologies, when lifting goods at four points, four lifting points are typically pre-set on the object to be lifted and connected by a lifting beam. The lifting beam usually consists of four independent lifting rods, and the goods are lifted using a crane hook via ropes and the lifting beam. This method has certain technical problems in practical use: First, when installing the hoisted object, the positions of the four hoisting rods may deviate in the vertical dimension, which increases the difficulty of inserting the rods during hoisting. Even if the rods are successfully inserted, it is difficult to adjust the balance of the hoisted object. Second, the structure lacks versatility. The hoisting beam adopts a fixed frame structure. For different objects to be hoisted, the four preset hoisting points are located at different positions. Therefore, hoisting beams of different sizes and specifications need to be set up for hoisting, or holes need to be customized for hoisting rods of different specifications, resulting in high hoisting costs. Third, in traditional four-point hoisting structures, the difficulty of threading the hoist is reduced by setting up independent hoisting rods with adjustable height. However, the independent hoisting rods only support single-dimensional adjustment, i.e., the height direction, and cannot simultaneously adjust the horizontal position deviation of the hoisted object in the front-back and left-right directions. This makes threading the hoisting rod still difficult, and the balance adjustment relies on repeated manual trial and error. When there are multi-dimensional deviations between the independent hoisting rods and the hoisting holes, multiple disassembly and reassembly or forced correction are required. For example, using a tool hammer to tap and adjust the horizontal position deviation is time-consuming and laborious, easily damages the hoisting structure, and is difficult to operate in a confined space. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-dimensional adjustable hoisting structure. The overall structure is simple, with multiple adjustable dimensions and a large adjustment range. It solves the problem of inconvenient balance adjustment of hoisted objects, improves hoisting connection accuracy and hoisting operation efficiency, and is particularly suitable for use in environments with limited installation space. It also reduces the labor intensity of installation workers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: In a first aspect, embodiments of this utility model provide a multi-dimensional adjustable hoisting structure, including a hoisting beam and a hoisting plate. The two ends of the hoisting beam are respectively provided with an elongated hole and a square hole. A slider is provided in the elongated hole and slidably connected to the elongated hole. The slider is rotatably connected to one end of the hoisting plate to install the hoisting plate on the hoisting beam. The other end of the hoisting plate is provided with a riveting nut hole, which is located above the square hole.

[0006] As a further technical solution, the hoisting beam is arranged in a rectangular structure.

[0007] As a further technical solution, the four sides of the hoisting beam are folded up to form a U-shaped cross-section.

[0008] As a further technical solution, the folded-up portions at both ends of the hoisting beam are provided with multiple bolts.

[0009] As a further technical solution, the thickness of the lifting plate is greater than the thickness of the lifting beam.

[0010] As a further technical solution, two elongated holes are symmetrically provided at both ends of the hoisting beam, and two square holes are symmetrically provided on the hoisting beam between the two elongated holes.

[0011] As a further technical solution, the geometric central axes of the two elongated holes along the length of the hoisting beam are on the same straight line.

[0012] As a further technical solution, the geometric centerlines of the two square holes along the length of the hoisting beam are on the same straight line.

[0013] As a further technical solution, the end of the hoisting plate near the square hole is configured as a trapezoidal structure.

[0014] As a further technical solution, the bottom of the slider is configured as a disc structure, and a strip structure adapted to the width of the elongated hole is provided above the disc structure, and a stepped cylindrical screw is provided above the strip structure.

[0015] The beneficial effects of the above-described embodiments of this utility model are as follows: The multi-dimensional adjustable hoisting structure provided by this utility model, compared with the traditional hoisting structure that only supports single-dimensional adjustment in the vertical direction, achieves dynamic compensation of two-dimensional degrees of freedom in the horizontal plane through the coordinated design of the elongated hole, the slider sliding pair and the hoisting plate rotating pair. The continuous sliding of the slider in the elongated hole realizes axial translation, compensating for the front-to-back deviation of the hoisted object. The radial adjustment of the hoisting plate around the slider axis eliminates the left-to-right positional error, giving the hoisting structure the ability to adjust and adapt to the plane. During the rod insertion process, the hoisting rod can be easily aligned with the riveting nut hole, avoiding damage to the hoisting structure caused by hammering and saving time and effort. The U-shaped beam structure forms continuous reinforcing ribs by folding up its four sides, which increases the moment of inertia of the section; the thickened hoisting plate forms a local shear fortress, suppressing the risk of instability caused by eccentric loads.

[0019] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] Example 1 In a typical embodiment of this utility model, such as Figure 1 As shown, a multi-dimensional adjustable hoisting structure is provided, including a hoisting beam 1 and a hoisting plate 2. The two ends of the hoisting beam 1 are respectively provided with an elongated hole and a square hole. A slider 4 is provided in the elongated hole and slidably connected to the elongated hole. The slider 4 can rotatably connect one end of the hoisting plate 2 to install the hoisting plate 2 on the hoisting beam 1. The other end of the hoisting plate 2 is provided with a riveting nut hole 3, which is located above the square hole.

[0021] This configuration, by installing independent lifting rods on the cargo and threading them to the rivet nut holes 3, allows for adjustment of the connection position between the independent lifting rods and the rivet nut holes 3, further enabling height adjustment of the hoisted cargo. Furthermore, the axial sliding of the slider 4 within the elongated hole and the radial deflection of the hoisting plate 2 around the slider 4 form a two-dimensional motion pair, synchronously compensating for the front-to-back and left-to-right positional deviations of the hoisted object in the horizontal plane. This adapts to the use of the hoisting beam 1 under various working conditions, allowing for adaptive assembly and hoisting of cargo of different specifications under different operating conditions, thus broadening the overall applicability of the hoisting structure.

[0022] In actual use, the rivets are first riveted to the lifting plate 2, and then the slider 4 is installed into the elongated hole of the lifting beam 1. The upper screw of the slider 4 passes through the pre-made mounting hole on the lifting plate 2, and the two are connected together with a nut. It does not need to be tightened. At this time, the strip structure on the slider 4 is adapted to the elongated hole.

[0023] Generally, two sets of this hoisting structure are used to form a four-point hoisting structure. When hoisting goods with rods, the fixed rods of the hoisting object are inserted one by one into the rivet nut holes 3. The front and back positions of the four sets of sliders 4 and the left and right positions of the hoisting plate 2 are adjusted to achieve a four-point balance of the hoisting object. Tightening the nuts on the sliders 4 can fix the position, and then the object can be hoisted.

[0024] Furthermore, the hoisting beam 1 is arranged in a rectangular structure. This arrangement allows the shear force to be evenly distributed along the four sides of the closed frame, suppressing plastic deformation caused by local stress concentration, and making the overall structure more robust and durable.

[0025] Furthermore, the four sides of the lifting beam 1 are folded up to form a U-shaped cross-section. This design creates a continuous reinforcing rib structure on the four sides, improving the strength of the lifting beam 1. At the same time, the central part is designed as a hollow structure, which reduces the weight of the lifting beam 1. This reduces material usage, and the lightweight lifting structure is more convenient to use.

[0026] Furthermore, the folded ends of the lifting beam 1 are equipped with multiple bolts. This arrangement forms a standard connection node, supporting the crane for connection and lifting.

[0027] Furthermore, the thickness of the lifting plate 2 is greater than the thickness of the lifting beam 1. This design allows the thickened lifting plate 2 to withstand the lateral impact of the independent lifting rods, eliminating the risk of tearing at the edge of the rivet nut hole 3. The high-rigidity plate body suppresses elastic deformation, thus improving the structural strength.

[0028] Furthermore, two elongated holes are symmetrically provided at each end of the lifting beam 1, and two square holes are symmetrically provided on the lifting beam 1 between the two elongated holes. This arrangement creates a stable adjustment structure with four symmetrical points, facilitating adjustment during use while effectively distributing eccentric loads. The independent hole positions isolate the movement interference of each adjustment point, achieving stability and convenient adjustment of the lifting structure.

[0029] Furthermore, the geometric centerlines of the two elongated holes along the length of the hoisting beam 1 are on the same straight line.

[0030] Furthermore, the geometric center axes of the two square holes along the length of the hoisting beam 1 are on the same straight line.

[0031] With the above settings, the double elongated holes coincide in axis, amplifying the adjustment stroke, while the collinear elongated holes and square holes provide a centering reference, facilitating the position adjustment of the lifting plate 2.

[0032] Furthermore, the end of the lifting plate 2 near the square hole is configured as a trapezoidal structure. When the lifting plate 2 rotates and adjusts around the slider 4, the trapezoidal structure at the end, when close to the folded structures on both sides of the lifting beam 1, can prevent rigid interference with the folded structures on both sides of the lifting beam 1, while increasing the range of rotation adjustment of the lifting plate 2.

[0033] Furthermore, the bottom of the slider 4 is configured as a disc structure, and above the disc structure is a strip structure adapted to the width of the elongated hole, and above the strip structure is a stepped cylindrical screw.

[0034] With this configuration, the disc-shaped base can suppress the overturning moment, the strip structure matching the elongated hole eliminates gap swaying while achieving stable adjustment along the axial direction of the elongated hole, and the upper stepped cylindrical screw can rotatably connect with the lifting plate 2 while ensuring structural stability. At the same time, it can be connected with the nut to fix the position after adjustment.

[0035] The multi-dimensional adjustable hoisting structure provided by this utility model, compared with the traditional hoisting structure that only supports single-dimensional adjustment in the vertical direction, achieves dynamic compensation of two-dimensional degrees of freedom in the horizontal plane through the coordinated design of the elongated hole, the slider sliding pair and the hoisting plate rotating pair. The continuous sliding of the slider in the elongated hole realizes axial translation, compensating for the front-to-back deviation of the hoisted object. The radial adjustment of the hoisting plate around the slider axis eliminates the left-to-right positional error, giving the hoisting structure the ability to adjust and adapt to the plane. During the rod insertion process, the hoisting rod can be easily aligned with the riveting nut hole, avoiding damage to the hoisting structure caused by hammering and saving time and effort. The U-shaped beam structure forms continuous reinforcing ribs by folding up its four sides, which increases the moment of inertia of the section; the thickened hoisting plate forms a local shear fortress, suppressing the risk of instability caused by eccentric loads.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
