A high-stability elevator balance compensation chain and manufacturing method

Abstract

The present invention discloses a high-stability elevator balance compensation chain and a manufacturing method. The lock ring has two sides with slots, and the slots on the two sides of the lock ring are provided with blocks. The blocks are fixed to the two sides of the lock ring by bolts. The lock rings are connected to each other. Rollers are provided at the two ends of the lock ring at the connection. The lock rings are wrapped with a rubber composite layer on the outside after connection. The invention has a reasonable structure. There will be no torsion between adjacent lock rings, which avoids deformation and rolling of the lock rings, thereby ensuring the stability of the elevator. There will be no collision between adjacent lock rings like in traditional compensation chains, and there will be no friction on the inside of the lock rings, thereby improving the service life of the elevator balance compensation chain. Through the cooperation of the external rubber composite layer, the elevator balance compensation chain will not have two other lock rings connected to one lock ring on the same side, thereby ensuring that the overall length of the elevator balance compensation chain is always maximized, and also ensuring the stability of the elevator.

Description

Technical Field

[0001] The invention relates to the technical field of elevator balancing and compensating chains, and in particular to a high-stability elevator balancing and compensating chain and a manufacturing method thereof. Background Art

[0002] Traditional elevator balance compensation chains are mostly made of traditional locking rings connected in sequence. During use, two adjacent locking rings are prone to rotation and sliding, causing the entire chain to roll, greatly reducing the stability of the elevator. In addition, since the rotating and sliding locking rings are prone to deformation and wear, the service life of the balance compensation chain will be greatly reduced. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Summary of the invention

[0003] The purpose of the present invention is to provide a high-stability elevator balance compensation chain and a manufacturing method. Adjacent locking rings will not have torque between each other, thus avoiding deformation and rolling of the locking rings, thereby ensuring the stability of the elevator. Unlike traditional compensation chains, adjacent locking rings will not collide with each other, and friction will not occur on the inner side of the locking rings, thereby improving the service life of the elevator balance compensation chain. Through the cooperation of the external rubber composite layer, the elevator balance compensation chain will not have two locking rings connected to one locking ring on the same side, thereby ensuring that the overall length of the elevator balance compensation chain is always maximized, and also ensuring the stability of the elevator, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-stability elevator balance compensation chain, comprising a locking ring, a block, a bolt, a roller, and a rubber composite layer, wherein the locking ring is provided with slots on both sides thereof, and blocks are arranged in the slots on both sides thereof, and the blocks are fixed to both sides of the locking ring by bolts, and the locking rings are connected to each other in pairs, and rollers are arranged at the connection points at both ends of the locking ring, and the outside of the connected locking ring is wrapped with a rubber composite layer.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 The present invention provides a technical solution: a high-stability elevator balance compensation chain, comprising a lock ring 1, a block 2, a bolt 3, a roller 4, and a rubber composite layer 5. The lock ring 1 has slots on both sides, the slots on both sides of the lock ring 1 are "convex", the distance between the two sides of the lock ring 1 is consistent with the thickness of the lock ring 1, and screw holes are respectively opened on both sides of the lock ring 1. Blocks 2 are arranged in the slots on both sides of the lock ring 1. The block 2 is fixed to both sides of the lock ring 1 by bolts 3. The bolts 3 are hexagon socket bolts. One side of the block 2 is "convex", and the other side of the block 2 is arched. The "convex" side of the block 2 is aligned with the slot of the lock ring 1. The block 2 is convex and has a screw hole on one side, the screw hole of the block 2 corresponds to the screw hole of the lock ring 1, the block 2 is arched and one side is arranged in the lock ring 1, the two lock rings 1 are connected to each other, and rollers 4 are also arranged at the connection points at both ends of the lock ring 1, and a groove is opened in the middle of the roller 4. The groove in the middle of the roller 4 matches with the two ends of the arched side of the block 2 and the end of the other lock ring 1. The groove opened by the roller 4 is arc-shaped. When the roller 4 is arranged between the blocks 2 on both sides, the roller 4 is respectively connected with the blocks 2 on both sides and the end of the other lock ring 1, and the outside of the connected lock ring 1 is wrapped with a rubber composite layer 5.

[0024] like Figure 2 As shown, the roller 4 is composed of a first body 41 and a second body 42 . A screw 43 is provided at one end of the first body 41 , and a screw hole is provided at one end of the second body 42 . The first body 41 is connected to the second body 42 through the screw 43 .

[0025] A method for manufacturing a high-stability elevator balance compensation chain comprises the following steps:

[0026] Step 1: Make the lock ring 1, the clamping block 2 and the roller 4 respectively, and connect all the lock rings 1 in sequence;

[0027] Step 2: Then insert the clamping block 2 into the clamping grooves on both sides of the lock ring 1 respectively, and fix the clamping block 2 on both sides of the lock ring 1 by bolts 3;

[0029] Step 4: Put the rubber composite layer 5 on the outside of the chain, and after heating it in a drying machine, the rubber composite layer 5 tightly wraps the chain, thereby completing the preparation of the anti-roll type elevator balance compensation chain.

[0030] Principle of use: Since rollers 4 are provided at both ends of each locking ring 1, the sliding of two adjacent locking rings 1 is limited by the rollers 4, and only two adjacent locking rings 1 can form an angle on the same plane, which produces the following beneficial effects. First, there will be no torque between the adjacent locking rings 1 of the elevator balance compensation chain, thereby avoiding deformation and rolling of the locking rings 1, thereby ensuring the stability of the elevator; second, there will be no collision between the adjacent locking rings 1 like traditional compensation chains, and no friction will occur on the inner side of the locking rings 1, thereby improving the service life of the elevator balance compensation chain; third, through the cooperation of the external rubber composite layer 5, the elevator balance compensation chain will not have two locking rings 1 connected to one locking ring 1 on the same side, thereby ensuring that the overall length of the elevator balance compensation chain is always maximized, and also ensuring the stability of the elevator.
