Description

Technical Field

[0001] This utility model relates to the field of circular link chain technology, specifically to a high-strength compact chain with an installation device. Background Technology

[0002] The chain consists of multiple metal links. Each link includes two straight sections and two curved sections connecting them. The side faces of the two straight sections on the same link are called side faces, and the side faces of the two straight sections on the same link that are far apart are called end faces. In the chain drive system of a scraper conveyor, the links are divided into flat links and vertical links according to their state during use. The side faces of the flat links are in contact with the sprocket, and the end faces of the vertical links are in contact with the sprocket. The flat links and vertical links are connected alternately. During the use of the chain drive system, sensors or trackers need to be installed at specific locations, and the installation positions of the sensors or trackers should not interfere with the sprockets during use. Currently, there is no good way to install sensors or trackers, and most of them are fixed by welding. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a high-strength compact chain with an installation device.

[0004] This utility model is achieved through the following technical solution: a high-strength compact chain with an installation device is provided, comprising staggered vertical rings and horizontal rings. Each vertical ring includes two straight vertical ring sections and two curved vertical ring sections. Each horizontal ring includes two straight horizontal ring sections and two curved horizontal ring sections. Each straight vertical ring section has an inwardly protruding intermediate protrusion. The distance between the two intermediate protrusions is smaller than the diameter of the curved horizontal ring section. The top of each intermediate protrusion has an installation groove, and an installation pin insertion space is formed between the two installation grooves.

[0005] In this design, the middle protrusion on the inner side of the straight ring separates the two connected flat rings, preventing misalignment and ensuring the normal operation of the chain. The space between the two mounting slots forms a space for inserting mounting pins. The mounting device can be inserted into this position, and then a sensor or tracker can be installed on the mounting device. Since this position does not contact the sprocket or other components, interference is unlikely to occur after installation.

[0006] As an optimization, a compression plane is provided on the outer side of the straight section of the vertical ring, and the cross-section of the straight section of the vertical ring is D-shaped. The compression plane increases the contact area between the outer side of the straight section of the vertical ring and the sprocket, reduces the pressure between the straight section of the vertical ring and the sprocket, and enhances the wear resistance of the straight section of the vertical ring.

[0007] As an optimization, the length of the central protrusion gradually decreases in the direction away from the straight portion of the vertical ring. In this design, the length of the central protrusion gradually decreases in the direction away from the straight portion of the vertical ring, which saves material, reduces stress concentration, increases the contact area with the arc-shaped portion of the flat ring, and reduces wear while ensuring separation capability.

[0008] As an optimization, the central protrusion is located in the middle of the straight section of the vertical ring. In this design, the central protrusion is located in the middle, thereby ensuring that the two flat rings are symmetrically and evenly connected.

[0009] As an optimization, the mounting groove is an arc-shaped groove, with two arc-shaped grooves concentric. This facilitates the insertion of mounting device structures with circular cross-sections.

[0010] As an optimization, the thickness of the central protrusion is less than the thickness of the straight portion of the vertical ring. This design reduces the thickness of the central protrusion, saving material.

[0011] As an optimization, the cross-section of the straight section and the cross-section of the curved section of the flat ring are both circular with equal diameters. In this design, the flat ring is formed by bending and butt-jointing round steel, which facilitates the connection of the two vertical rings and makes processing easier.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a high-strength compact chain with an installation device. The two flat rings connected on the vertical plate are separated by the middle protrusion of the inner side of the vertical ring, which prevents the two flat rings from being misaligned and ensures the normal operation of the chain. An installation pin insertion space is formed between the two installation slots. The installation device (usually an installation ring) can be inserted into this position, and then a sensor or tracker can be installed on the installation device, which is convenient for installation.

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] like Figures 1-5 As shown, this utility model discloses a high-strength compact chain with an installation device, comprising staggered vertical and horizontal rings. Each horizontal ring includes two straight sections 21 and two arc-shaped sections 22. The cross-sections of the straight sections 21 and the arc-shaped sections 22 are both circular with equal diameters. The structure of the horizontal ring is a common circular chain link. The horizontal ring can be formed by bending round steel. During bending, adjacent vertical rings are connected, thus the vertical rings can be pre-processed into a ring structure.

[0022] The vertical ring includes two straight sections 11 and two arc-shaped sections 12. The outer side of the straight section 11 is provided with an extrusion plane 14. Here, the outer side refers to the side where the two straight sections 11 are far apart from each other. The extrusion plane 14 is formed by extrusion from the outside. After extrusion, the cross section of the straight section 11 is D-shaped.

[0023] The straight section 11 of the vertical ring is provided with a middle protrusion 13 that protrudes inward. The inner side refers to the side where the two straight sections 11 of the vertical ring are close to each other. The middle protrusion 13 is located in the middle of the straight section 11 of the vertical ring and is integrally formed with the straight section 11 of the vertical ring.

[0024] The two intermediate protrusions 13 are set separately, and the distance between the two intermediate protrusions 13 is smaller than the diameter of the flat ring arc portion 22, thereby preventing the flat ring from passing through the space between the two intermediate protrusions 13.

[0025] The length of the intermediate protrusion 13 gradually decreases in the direction away from the straight portion 11 of the vertical ring. That is... Figure 3 The dimensions of the central protrusion 13 gradually decrease in the direction away from the straight section 11 of the vertical ring.

[0026] like Figure 5 As shown, the thickness of the intermediate protrusion 13 is less than the thickness of the straight portion 11 of the vertical ring. The connection between the intermediate protrusion 13 and the straight portion 11 of the vertical ring is rounded, thereby making the connection smooth.

[0027] like Figure 3 As shown, the top of the intermediate protrusion 13 is provided with a mounting groove 15, which is an arc-shaped groove with two concentric arc-shaped grooves. A mounting pin insertion space is formed between the two mounting grooves 15, through which a mounting device can be inserted and then a sensor or tracker can be mounted.

[0028] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
