Description

Technical Field

[0001] The present application relates to the technical field of chains, and specifically to a new type of chain. Background Art

[0002] A chain is generally a metal link or ring, and is mostly used for mechanical transmission and traction. There are many types of chains, but their basic structures are only the following several types, such as drive chains, conveyor chains, detachable chains, and plate chains, etc. Others are variations of these several types. Most chains are composed of components such as chain plates, chain pins, and bushings.

[0003] Patent Publication No. CN216867420U discloses a new type of tensile drill chain. This new type of tensile drill chain is provided with a reinforcement mechanism. The reinforcement mechanism is inserted into the chain roller part and locked by a magic buckle, and is paired with a limiting plate B and a limiting block to clamp the outer chain A and the outer chain B, so as to perform reinforcement and locking treatment on the installation between the parts of the chain, effectively realizing the tensile effect of the drill chain and improving the firmness and stability of the drill chain. However, the method of enhancing the firmness of the drill chain by strengthening the connection tightness between the outer chain and the inner chain cannot achieve the purpose of greatly enhancing the tensile effect of the drill chain. The damage suffered by the drill chain during use has not been reduced, and the loss of the drill chain has not been decreased either. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present application provides a new type of chain, which solves the problems mentioned in the above background art.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present application is realized through the following technical solutions: A new type of chain includes a connection mechanism, an inner chain plate for connecting the outer chain, and an assembly mechanism for installing the chain assembly. An outer chain mechanism that can adjust the chain spacing to relieve pressure when the pressure borne by the chain is too high is slidably connected to the surface of the connection mechanism. The outer chain mechanism includes a double annular opening and a double annular groove. The double annular opening is arranged at the upper and lower ends of the connection mechanism, and the double annular groove is arranged below the inner chain plate. The bottom of the inner chain plate is attached to the surface of the connection mechanism, and the assembly mechanism is arranged inside the connection mechanism.

[0008] By adopting the above technical solutions, it is possible to facilitate the adjustment of the tightness between the inner chain plate and the outer chain mechanism by using the double annular opening and the double annular groove, and reduce the possibility of the drill chain breaking due to excessive pulling during use.

[0009] Preferably, the outer chain mechanism further includes an upper plate and a placement groove. Double annular openings are provided at both ends of the upper plate and both ends of the inner chain plate. The inner wall of the double annular opening is in contact with the side surface of the connecting mechanism. The placement grooves are provided on both sides of the top of the upper plate, and the placement grooves communicate with the double annular openings.

[0010] By adopting the above technical solution, the placement groove on the top of the upper plate can be used to make the nut at the top of the bolt flush with the top of the upper plate, preventing the bolt from rotating and causing the chain to become disconnected under non-artificial adjustment.

[0011] Preferably, the outer chain mechanism further includes a lower plate. Double annular grooves are provided on both sides of the top of the lower plate. The inner wall of the double annular groove is in contact with the lower side surface of the connecting mechanism. The double annular groove has the same shape and size as the double annular opening.

[0012] By adopting the above technical solution, the double annular groove provided on the lower plate can be used to prevent external substances from entering the vacant part of the double annular groove and causing the connecting rod to be unable to move in the double annular groove.

[0013] Preferably, the connecting mechanism includes a connecting rod and a spacer tube. The side surface of the connecting rod is in contact with the inner wall of the double annular opening and the inner wall of the double annular groove respectively. The spacer tube is fixedly connected to the surface of the connecting rod, and both the upper and lower ends of the spacer tube are in contact with the surface of the inner chain plate.

[0014] By adopting the above technical solution, the spacer tube on the surface of the connecting rod can be used to separate the inner chain plates so that the distance between them is in a stable state, facilitating the movement of the gear teeth.

[0015] Preferably, the assembling mechanism includes a threaded groove and a bolt. The threaded groove is provided at the top of the connecting rod. The surface of the bolt is threadedly connected to the threaded groove, and the nut at the top of the bolt is in contact with the placement groove.

[0016] By adopting the above technical solution, the threaded groove can be used to facilitate the rotation of the bolt to fix the upper plate and the upper inner chain plate on the upper surface of the connecting rod, improving the stability of the relative position of the upper plate and the upper inner chain plate when the chain rotates.

[0017] Preferably, the assembling mechanism further includes a movable cavity and a limiting rod. The movable cavity is provided at the bottom of the connecting rod. The movable cavity communicates with the threaded groove. A sliding groove is provided on the side surface of the movable cavity. The surface of the limiting rod is slidably connected to the movable cavity. A limiting block is fixedly connected to the bottom of the limiting rod. A sliding rod is fixedly connected to the side surface of the limiting rod. The surface of the sliding rod is slidably connected to the sliding groove.

[0018] By adopting the above technical solution, the movable cavity can be used to facilitate the up and down movement of the limiting rod whose sliding rod on the side surface is slidably connected to the sliding groove. When the bolt moves downwards, it drives the limiting block at the bottom of the limiting rod to move downwards until it is in contact with the limiting groove, playing the role of limiting the limiting rod.

[0019] Preferably, the assembling mechanism further includes a rotating rod and a movable groove. The surface of the rotating rod is slidably connected to the movable cavity. A limiting groove is formed at the top of the rotating rod, and the shape and size of the limiting groove are the same as those of the limiting block. A control plate is fixedly connected to the right side of the rotating rod. The movable groove is formed on the right side of the movable cavity, and the movable groove is slidably connected to the surface of the control plate.

[0020] By adopting the above technical solution, the control plate in the movable groove can be rotated to drive the rotating rod with the limiting groove formed at the top to rotate, so as to adjust the rotating rod to a proper angle.

[0021] Preferably, the assembling mechanism further includes a downward movement groove and a retaining rod. The downward movement groove is formed on one side of the double annular groove. An arc-shaped groove is formed at the bottom of the downward movement groove. A receiving groove is formed at the rear side of the bottom of the double annular groove. The retaining rod is fixedly connected to the bottom of the rotating rod, and both ends of the retaining rod are slidably connected to the arc-shaped groove and the receiving groove respectively.

[0022] By adopting the above technical solution, the downward movement groove can facilitate the movement of the retaining rod to one end of the arc-shaped groove. The rotation of the rotating rod drives the retaining rod to rotate to one end to fit with the other end of the arc-shaped groove, and the other end of the retaining rod fits with one end of the receiving groove, so as to connect the lower plate and the connecting rod, improving the simplicity of chain assembly.

[0023] (III) Beneficial effects

[0024] This application provides a new type of chain, with the following beneficial effects:

[0025] 1. For this new type of chain, by setting the outer chain mechanism, the double annular opening at the bottom of the placement groove formed at the top of the upper plate and the double annular groove formed at the top of the lower plate provide a certain range of movement for the connecting rod, expanding the range of movement of the teeth formed by the connection between the outer chain and the inner chain, enhancing the anti-tensile effect of the drilling rig chain, reducing the possibility of damage to the drilling rig chain caused by pulling during use, reducing the loss of the drilling rig chain, and extending the service life of the drilling rig chain.

[0026] 2. For this new type of chain, by setting up an assembly mechanism, one end of the retaining rod is moved along the downward movement groove to fit with the arc-shaped groove. Rotating the control plate in the movable groove drives the rotating rod to rotate. The rotation of the rotating rod drives the retaining rod in the arc-shaped groove to rotate. The retaining rod rotates until one end fits with one side of the arc-shaped groove and the other end fits with one side of the receiving groove. Align the bolt with the threaded groove and rotate the bolt so that it moves downward to fit with the top of the limiting rod at the bottom. The downward movement of the bolt drives the side sliding rod and the limiting rod slidingly connected to the chute on one side of the movable cavity to move downward. The limiting rod moves downward until the limiting block fits with the bottom of the limiting groove. At the same time, the nut on the top of the bolt fits with the placement groove, achieving the purpose of connecting the upper plate, lower plate and inner chain plate with the connecting rod, improving the convenience of chain assembly, shortening the time required for chain assembly, and the detachable chain assembly method is more convenient for overhaul and replacement of the chain, improving the cost performance of the chain.
