Technical Field

[0001] The utility model relates to the technical field of monorail cranes, in particular to a monorail crane chain hanging point structure. Background Art

[0002] When a monorail crane is used to transport large cargo, a lifting beam is required. The lifting beam is usually composed of a multi-level beam body, and the upper and lower beam bodies are usually connected by a circular chain. When the lifting beam passes through a curve, or when the cargo shakes and swings during transportation, the chain will twist and tilt, causing damage or even destruction to the chain. In addition, the fixed structure of the chain should be easy to adjust and replace in length. Utility Model Content

[0003] Aiming at the deficiencies of the prior art, the utility model provides a monorail hanging chain hanging point structure.

[0004] The utility model is realized through the following technical scheme, and provides a monorail chain suspension point structure, comprising a circular link chain and a support plate, wherein the support plate is provided with a circular link chain through hole, and further comprising a thrust bearing and two horizontally symmetrically arranged semicircular chain plates, wherein the upper end surface of the support plate is provided with a circular countersunk hole for accommodating the thrust bearing, and the two chain plates constitute a chain column whose lower end is inserted into the inner ring of the thrust bearing, and the chain plate is fixedly connected with an upper retaining edge located at the outer ring of the chain column, and the two chain plates are provided with a single-sided vertical ring groove on one side close to each other, and a single-sided flat ring groove is provided on the upper end surface of the single-sided vertical ring groove, and the two single-sided vertical ring grooves constitute a vertical ring through hole for accommodating the vertical ring of the circular link chain, and the lower end of the flat ring of the circular link chain is supported on the two single-sided flat ring grooves.

[0005] In this scheme, two chain plates are assembled at appropriate positions on the circular link chain, so that a circular link chain vertical ring on the circular link chain is located in the vertical ring passing hole, and the lower end of the circular link chain flat ring above the circular link chain vertical ring is supported on two single-sided flat ring grooves, and the chain column after the two chain plates are assembled is inserted downward into the inner hole of the thrust bearing, and the upper retaining edge is supported on the upper end face of the thrust bearing, thereby achieving the fixation of the circular link chain. When the circular link chain rotates, the thrust bearing rotates with it to prevent the circular link chain from being torsionally damaged. When the circular link chain is obliquely pulled, relative deflection can occur between the circular link chain flat ring and the single-sided flat ring groove, thereby achieving the oblique pulling of the circular link chain. When the length of the circular link chain needs to be adjusted, the two chain plates are taken out upwards and separated, and the circular link chain vertical ring and the circular link chain flat ring at appropriate positions are clamped between the two chain plates, thereby adjusting the length of the circular link chain.

[0006] As an optimization, the upper ribs of the two chain plates form a circular ring structure. In this solution, the upper ribs of the two chain plates form a circular ring structure, so that support is achieved through the circular ring structure, and the support strength is high.

[0007] As an optimization, the vertical ring through hole is a long hole, so as to adapt to the external dimensions of the vertical ring of the round ring chain.

[0008] As an optimization, the single-sided vertical ring groove is a spherical surface, so that the flat ring of the round link chain can achieve a certain deflection in the spherical groove, which is convenient for realizing the oblique pulling of the round link chain.

[0009] As an optimization, a protective cover wrapped around the outer ring of the thrust bearing is also included. The protective cover in this solution protects the outer ring of the thrust bearing and prevents dust from entering.

[0010] As an optimization, the upper end of the protective cover extends to between the upper rib and the thrust bearing, so that the protective cover is pressed against the thrust bearing through the upper baffle to prevent it from coming out.

[0011] The beneficial effects of the utility model are as follows: a monorail crane chain hanging point structure of the utility model can realize the fixed installation of the circular link chain and the support plate, and the installed hanging point structure can realize the rotation and oblique pulling of the circular link chain, thereby preventing the circular link chain from being damaged by twisting or oblique pulling, and the lifting length of the circular link chain can be adjusted arbitrarily to meet the lifting requirements of the monorail crane.

[0025] The circular link chain is formed by connecting a plurality of chain links. For the convenience of description, the circular link chain in the present application is formed by staggered connection of a plurality of circular link chain vertical links 4 and circular link chain horizontal links 5, and adjacent circular link chain vertical links 4 and circular link chain horizontal links 5 are vertically arranged.

[0026] It also includes a thrust bearing 1, the outer ring of the thrust bearing 1 is relatively fixed to the support plate 6, the inner ring of the thrust bearing 1 is connected to the round link chain, the upper end surface of the support plate 6 is provided with a circular countersunk hole for accommodating the thrust bearing 1, the lower end of the outer ring of the thrust bearing 1 is inserted into the circular countersunk hole to prevent it from moving horizontally, and the circular countersunk hole is concentrically arranged with the through hole of the round link chain.

[0027] It also includes two semicircular chain plates 3 that are symmetrically arranged horizontally. The two chain plates 3 are on the same horizontal plane and are symmetrically arranged bilaterally. The planes of the two chain plates 3 fit together, so that the two chain plates 3 form a chain column with the lower end inserted into the inner ring of the thrust bearing 1. The outer ring of the lower end of the chain column fits with the inner ring of the thrust bearing 1 and rotates with the inner ring of the thrust bearing 1.

[0028] In order to prevent the two chain plates 3 from falling, an upper rib 33 located on the outer ring of the chain column is fixed to the chain plate 3. The upper rib 33 in this embodiment is an integrally formed structure with the chain plate 3, and is a semi-annular structure protruding outward on the outer arc surface of the chain plate 3. Therefore, the upper rib 33 of the two chain plates 3 constitutes a circular structure, and the lower end surface of the upper rib 33 is supported on the upper end surface of the inner ring of the thrust bearing 1.

[0029] The two chain plates 3 are provided with a single-sided vertical ring groove 31 on the side close to each other. The two single-sided vertical ring grooves 31 constitute a vertical ring through hole for the circular chain vertical ring 4 to pass through. The vertical ring through hole is a long hole. The butt joint surface of the two chain plates 3 is coplanar with the long strip center of the long hole. The projection of the circular chain vertical ring 4 on the horizontal plane is a long strip, so the circular chain vertical ring 4 is accommodated in the vertical ring through hole, which can achieve a certain positioning and prevent large-scale movement.

[0030] The upper end surface of the unilateral vertical ring groove 31 is provided with a unilateral flat ring groove 32, and the unilateral vertical ring groove 31 is a spherical surface. The lower end of the round chain flat ring 5 is supported on the two unilateral flat ring grooves 32.

The upper end of the protective cover 2 extends horizontally inwards, and the upper end of the protective cover 2 extends between the upper rib 33 and the thrust bearing 1. The outer ring of the lower end surface of the upper rib 33 is provided with an annular groove, and the part of the upper end of the protective cover 2 extending horizontally inwards is accommodated in the annular groove.

[0032] The use of the utility model:

[0033] During installation, the thrust bearing 1 is placed in the circular countersunk hole on the upper end face of the support plate 6 for positioning, the chain passes through the thrust bearing 1 and the round-ring chain through-hole on the support plate 6, the protective cover 2 is covered on the thrust bearing 1, and the two chain plates 3 are assembled at appropriate positions on the round-ring chain, so that a round-ring chain vertical ring 4 on the round-ring chain is located in the vertical ring through-hole, and the lower end of the round-ring chain flat ring 5 above the round-ring chain vertical ring 4 is supported on two single-sided flat ring grooves 32, and the chain column after the two chain plates 3 are assembled is inserted downward into the inner hole of the thrust bearing 1, and the upper retaining edge 33 is supported on the upper end face of the thrust bearing 1, thereby achieving the fixation of the round-ring chain.

[0034] When the round link chain rotates, the thrust bearing rotates with it to prevent the round link chain from being torsionally damaged. When the round link chain is obliquely pulled, relative deflection can occur between the round link chain flat ring 5 and the single-sided flat ring groove 32, thereby realizing the oblique pulling of the round link chain.

[0035] When the length of the circular link chain needs to be adjusted, the two chain plates 3 are taken out upward and separated, and the vertical rings 4 and the horizontal rings 5 ​​of the circular link chain at appropriate positions are clamped between the two chain plates 3, so as to adjust the length of the circular link chain to meet the lifting requirements of the monorail crane.
