Description

Technical Field

[0001] This utility model relates to the field of building hoisting technology, and more specifically, to a spherical rotatable hoisting seat. Background Technology

[0002] A hoisting bracket is used to install lifting equipment (such as a hoist), and it also has lifting holes for the hoisting rope to pass through. The lifting equipment uses the hoisting rope to lift building components (such as steel connecting corridors). Most existing hoisting brackets are integral structures that provide support. However, under certain working conditions, the hoisting rope is not vertically downward, but at a certain angle to the vertical direction. This causes the rope to be subjected to oblique force, which leads to accelerated wear between the rope and the lifting hole. Furthermore, the contact point between the lifting hole and the rope is prone to premature fatigue cracks, severely affecting the service life of both the rope and the hoisting bracket. Utility Model Content

[0003] The purpose of this invention is to provide a spherical rotatable hanger to solve the above-mentioned defects of existing hangers when used in special working conditions.

[0004] This utility model is achieved through the following technical solution:

[0006] The connecting support with a ball hole at the top is provided with a fixed lifting hole that extends through the height direction;

[0007] The steering seat includes a ball and a steering base plate. The ball mates with a ball hole, and the steering base plate is located on top of the ball for mounting a lifter. The steering seat has a steering lifting hole that extends through the height direction.

[0008] And several elastic elements are located between the steering base plate and the connecting support.

[0009] Optionally, the elastic element is a helical spring.

[0016] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the steering seat and the connecting support are connected by a ball and a ball hole, allowing the steering seat to rotate at any angle within the target range. At the same time, the steering seat and the connecting support are provided with several elastic elements, which enable the steering seat and the lifting device to rotate adaptively according to the direction of the force on the lifting rope when the rope is subjected to oblique force, thereby greatly reducing the wear between the lifting rope and the lifting hole and avoiding excessive impact on the service life of the lifting rope and the lifting seat.

[0023] Example 1

[0024] refer to Figure 1 A spherical rotatable suspension bracket includes a connecting support 1, a steering seat 2, and several elastic elements 3.

[0025] The connecting support 1 has a ball hole 101 at its top. The steering seat 2 includes a ball 201 and a steering base plate 202. The ball 201 engages with the ball hole 101, allowing the steering seat 2 to rotate relative to the connecting support 1. The steering base plate 202 is located on top of the ball 201. The two are integrally formed or welded together. It should be understood that a gap is left between the steering base plate 202 and the connecting support 1 to allow the steering seat 2 to rotate at any angle within the target range. At the same time, the top surface of the connecting support 1 also serves as a rotation limit for the steering seat 2, restricting the steering seat 2 to its extreme rotational position.

[0026] In practical applications, the lifter 4 is installed on the top of the steering base 2. A fixed lifting hole 102 is provided through the connecting support 1, and a steering lifting hole 203 is provided through the steering base 2. The lifting rope (not shown) passes through the fixed lifting hole 102 and the steering lifting hole 203 and is then connected to the lifter 4. An elastic element 3 is located between the steering base plate 202 and the connecting support 1. During use, when the lifting rope is subjected to oblique force, the steering base 2 and the lifter 4 can adaptively rotate according to the direction of the force on the lifting rope, thereby significantly reducing wear between the lifting rope and the lifting hole and avoiding excessive impact on the service life of the lifting rope and the base. The number of elastic elements 3 is not specifically limited. In practical applications, several are arranged in a circular array around the center of the fixed lifting hole 102, or multiple pairs are symmetrically arranged about the center of the fixed lifting hole 102.

[0027] As an alternative, in this embodiment, the elastic element 3 is a helical spring. When the elastic element 3 is a helical spring, the lower end of the helical spring is fixed to the connecting support 1 by welding, riveting or other means, and the upper end abuts against the steering base plate 202.

[0028] refer to Figure 2 In this embodiment, the sidewall of the ball hole 101 is provided with several lubrication grooves 103, which can store lubricating oil to keep the steering seat 2 rotating smoothly. Furthermore, the sidewall of the ball hole 101 and the surface of the ball 201 are provided with a smooth, wear-resistant coating to improve wear resistance and smoothness. The coating thickness is 0.2-0.5 mm, and the coating material is not limited, such as alumina ceramic coating, polytetrafluoroethylene coating, metal carbide coating, graphene coating, etc.

[0029] The bottom edges of both the fixed lifting hole 102 and the steering lifting hole 203 are rounded with a radius of 3-5 mm. Furthermore, a smooth, wear-resistant coating is applied to the walls of both the fixed lifting hole 102 and the steering lifting hole 203 to improve wear resistance and smoothness, reducing friction and wear on the hole walls and the lifting rope. Similarly, the coating thickness is 0.2-0.5 mm, and the coating material is not limited, such as alumina ceramic coating, polytetrafluoroethylene coating, metal carbide coating, graphene coating, etc.

[0030] In this embodiment, when not in use, the steering base plate 202 and the connecting support 1 are connected and fixed by bolts (not shown) to prevent them from separating and being lost.

[0031] Example 2

[0032] refer to Figure 3 The difference between this embodiment and Embodiment 1 lies in the selection of the elastic element 3. In this embodiment, the elastic element 3 is a hydraulic spring. The lower end of the elastic element 3 is fixedly connected to the connecting support 1, and the upper end of the elastic element 3 abuts against the steering base plate 202. When the elastic element 3 is a hydraulic spring, the hydraulic spring is installed on the connecting support 1, and its upper end abuts against the bottom of the steering base plate 202. Furthermore, in practical applications, the top of the hydraulic spring can be designed as a hemispherical shape to allow the steering seat 2 to rotate smoothly. In actual use, when the hoisting rope is subjected to an oblique force, the steering seat 2 and the lifting device 4 rotate accordingly. The state before rotation is as follows: Figure 4 As shown, the state after rotation is as follows Figure 5 As shown (easy to understand), Figure 5 This only represents a certain rotation angle and does not mean that the state will be the same after each rotation.

[0033] In other embodiments, the elastic element 3 can also be a gas spring, and the gas spring is configured in the same way as the hydraulic spring.

[0034] Example 3

[0035] This embodiment is a further optimization based on Embodiment 1 (and can also be further optimized based on Embodiment 2). Specifically, in this embodiment, the sphere 201 can be formed by forging, and the material is high-quality alloy steel. Its sphere diameter tolerance is controlled within ±0.1mm, the surface hardness is not less than HRC40, and it has undergone fine grinding and polishing treatment, with a surface roughness Ra value not greater than 0.2μm. This ensures that it has a low coefficient of friction and good wear resistance during contact with the suspension rope and rotation, reduces wear on the suspension rope, and ensures smooth rotation.

[0036] In addition, the entire surface of the spherical rotatable suspension base can be coated with a protective paint layer. The protective paint layer adopts a composite coating system of epoxy zinc-rich primer and polyurethane topcoat. The dry film thickness of the primer is between 60-80μm, and the dry film thickness of the topcoat is between 80-100μm. This protective paint layer has good weather resistance, corrosion resistance and scratch resistance, and can protect the suspension base from corrosion and damage in harsh industrial or outdoor environments for a long time, maintaining the appearance quality and structural performance of the suspension base.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
