Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and particularly to an anti-slip structure for a climbing conveyor. Background Art

[0002] A belt conveyor is a machine that transports materials by the endless movement of a belt. The belt conveyor has the advantages of long transportation distance, large transportation capacity, small working resistance, convenient installation, low power consumption, and less wear. When the inclination angle of the belt telescopic machine is adjustable, a climbing machine is formed, which is suitable for the continuous transportation of goods between floors or at height differences. When transporting upwards, the inclination angle is required not to be greater than 18°. When it is greater than 18°, the goods will slide down and cannot be pulled up.

[0003] The utility model patent "A climbing conveyor" with the publication number of CN216036997U discloses a climbing conveyor. By providing a retaining strip on the conveyor belt, which is designed in a meandering structure, it can block the goods and prevent the goods from falling. At the same time, when the goods are being transported, they contact the baffle on the side wall of the inclined conveyor frame. The inclined baffle rotates under force and is elastically supported by a second spring, which will not affect the transportation of the goods. At the same time, the elastic return of the baffle can block the goods and further prevent the goods from falling.

[0004] In order to prevent the items from sliding down during the transportation process, some anti-slip measures are adopted. For example, during the manufacturing process of the conveyor belt, integrally formed anti-slip patterns are provided on the surface. The anti-slip patterns will be worn out recently during use. After wear, the entire conveyor belt needs to be replaced, and the replacement cost is high. Therefore, an anti-slip structure for a climbing conveyor needs to be designed. Content of the Utility Model

[0005] Aiming at the above technical problems, the purpose of the utility model is to overcome the problem that the anti-slip patterns on the conveyor belt need to replace the entire conveyor belt after being worn, and the subsequent replacement cost is high in the prior art.

[0006] To achieve the above purpose, the utility model provides an anti-slip structure for a climbing conveyor, including: a middle connecting seat fixedly assembled on the conveyor belt, a pair of end connecting seats symmetrically arranged with respect to the middle connecting seat and fixedly assembled on the conveyor belt, and a V-shaped flexible chain capable of contacting the conveyor belt. The end connecting seat is located on one side of the middle connecting seat close to the conveying direction of the conveyor belt.

[0007] The V-shaped flexible chain includes a middle connecting block detachably connected to the middle connecting seat, a pair of end connecting blocks respectively detachably connected to the corresponding end connecting seats, and a pair of flexible connecting strips symmetrically arranged with respect to the middle connecting block and hinged to the middle connecting block at one end through a first hinge shaft. The length direction of the first hinge shaft is consistent with the width direction of the conveyor belt. The end of the flexible connecting strip far from the middle connecting block is hinged to the end connecting block through a second hinge shaft parallel to the first hinge shaft.

[0008] Preferably, the flexible connecting strip includes resistance blocks in sequential contact. Adjacent resistance blocks are connected through a third hinge shaft parallel to the first hinge shaft, and a plurality of third hinge shafts are arranged in sequence in a staggered manner along the direction close to the middle connecting block.

[0009] Preferably, a convex block portion protrudes on the side of the end connecting seat far from the conveyor belt, a groove portion matching the convex block portion is recessed on the end connecting block, and the end connecting block is connected to the end connecting seat through at least one mounting bolt;

[0010] A threaded hole is provided on the convex block portion, and a through hole for the mounting bolt to pass through and matching the threaded hole is provided on the end connecting block.

[0011] Preferably, the middle connecting seat includes a sliding strip portion with a length direction perpendicular to the width direction of the conveyor belt and a limiting portion fixedly provided at the end of the sliding strip portion close to the end connecting seat. An installation sliding groove matching the sliding strip portion is recessed on the side of the middle connecting block close to the conveying direction of the conveyor belt.

[0012] Preferably, both the end connecting seat and the middle connecting seat are assembled on the conveyor belt through a plurality of rivets.

[0013] Preferably, two counterbore holes with parallel axes are provided on each resistance block.

[0014] According to the above technical solution, the beneficial effects of an anti-slip structure of a climbing conveyor provided by the present utility model during use are as follows: First, when the V-shaped flexible chain needs to be replaced, the end connecting block is separated from the corresponding end connecting seat, and then the middle connecting block is separated from the corresponding middle connecting seat, and the V-shaped flexible chain can be disassembled. Then, a new V-shaped flexible chain is installed on the middle connecting seat and the end connecting seat, and the subsequent replacement cost is low;

[0015] Second, when the conveyor belt passes through the turning area, the V-shaped flexible chain will deform to pass through the turning area and will not pull the conveyor belt, which can improve the service life of the conveyor belt and the V-shaped flexible chain;

[0016] Third, the shape of the V-shaped flexible chain is V-shaped. When the items roll, the items can also be gathered towards the middle connecting seat to prevent the items from rolling off the transmission edge.

SPECIFIC IMPLEMENTATION

[0028] The following will describe in detail the specific implementation of the present utility model with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present utility model and does not limit the present utility model.

[0029] In the present utility model, unless otherwise specified, the directional terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0030] As Figures 1-7 shown, an anti-slip structure for a slope conveyor includes: a middle connecting seat 1 fixedly assembled on the conveyor belt, a pair of end connecting seats 2 symmetrically arranged with respect to the middle connecting seat 1 and fixedly assembled on the conveyor belt, and a V-shaped flexible chain capable of contacting the conveyor belt. The end connecting seat 2 is located on one side of the middle connecting seat 1 close to the conveying direction of the conveyor belt;

[0031] The V-shaped flexible chain includes a middle connecting block 3 detachably connected to the middle connecting seat 1, a pair of end connecting blocks 4 respectively detachably connected to the corresponding end connecting seats 2, and a pair of flexible connecting strips symmetrically arranged with respect to the middle connecting block 3 and having one end of each hinged to the middle connecting block 3 through a first hinge shaft 5. The length direction of the first hinge shaft 5 is the same as the width direction of the conveyor belt. The end of the flexible connecting strip away from the middle connecting block 3 is hinged to the end connecting block 4 through a second hinge shaft 6 parallel to the first hinge shaft 5.

[0032] When the conveyor belt is inclined, the V-shaped flexible chain can intercept the items sliding downward; when the V-shaped flexible chain needs to be replaced, the end connecting block 4 is separated from the corresponding end connecting seat 2, and then the middle connecting block 3 is separated from the corresponding middle connecting seat 1, and the V-shaped flexible chain can be disassembled, and then a new V-shaped flexible chain can be installed on the middle connecting seat 1 and the end connecting seat 2; when the conveyor belt passes through the turning area, the V-shaped flexible chain will deform to pass through the turning area, which can also improve the service life of the conveyor belt and the V-shaped flexible chain; because the shape of the V-shaped flexible chain is V-shaped, when the items roll, the items can also be gathered towards the middle connecting seat 1 to prevent the items from rolling off the transmission edge.

[0033] The flexible connecting strip includes resistance blocks 13 that are sequentially in contact. Adjacent two resistance blocks 13 are both connected through a third hinge shaft 7 parallel to the first hinge shaft 5, and a plurality of third hinge shafts 7 are sequentially arranged in a staggered manner along the direction close to the middle connecting block 3.

[0034] Because the first hinge shaft 5, the second hinge shaft 6 and the third hinge shaft 7 are arranged parallel to each other, when the V-shaped flexible chain passes through the turning area of the conveyor belt, the resistance blocks 13 will rotate around the corresponding third hinge shafts 7, so that adjacent two resistance blocks 13 will contact the arc part of the conveyor belt, enabling the flexible connecting strip to smoothly pass through the turning area of the conveyor belt.

[0035] A bump portion 8 is protrudingly provided on one side of the end connecting seat 2 away from the conveyor belt. A groove portion matching the bump portion 8 is recessedly provided on the end connecting block 4. The end connecting block 4 is connected to the end connecting seat 2 by at least one mounting bolt 9.

[0036] A threaded hole is provided on the bump portion 8, and a through hole for the mounting bolt 9 to pass through and matching the threaded hole is provided on the end connecting block 4.

[0037] When the V-shaped flexible chain needs to be replaced, loosen and remove the mounting bolt 9, and move the end connecting block 4 away from the end connecting seat 2, then the end connecting block 4 can be separated from the end connecting seat 2. The cooperation between the groove portion and the bump portion 8 can play a role in fixing the end connecting block 4, and the cooperation with the mounting bolt 9 can improve the mounting firmness of the end connecting block 4.

[0038] The middle connecting seat 1 includes a slide bar portion 10 whose length direction is perpendicular to the width direction of the conveyor belt, and a limiting portion 11 fixedly provided at the end of the slide bar portion 10 close to the end connecting seat 2. An installation chute 12 matching the slide bar portion 10 is recessedly provided on one side of the middle connecting block 3 close to the conveying direction of the conveyor belt.

[0039] When the V-shaped flexible chain needs to be replaced, after the end connecting block 4 is separated from the end connecting seat 2, pull the middle connecting block 3 away from the end connecting seat 2, driving the middle connecting block 3 to slide away from the limiting portion 11 on the slide bar portion 10 until the middle connecting block 3 is separated from the slide bar portion 10.

[0040] When installing the V-shaped flexible chain, slide the middle connecting block 3 from the end of the slide bar portion 10 away from the limiting portion 11 and sleeved on the slide bar portion 10 until it contacts the limiting portion 11, and then fix the end connecting block 4 and the end connecting seat 2. After the end connecting block 4 and the end connecting seat 2 are connected, the middle connecting block 3 cannot move away from the limiting portion 11.

[0041] Both the end connecting seat 2 and the middle connecting seat 1 are assembled on the conveyor belt by a plurality of rivets.

[0042] Two countersunk holes with parallel axes are provided on each of the resistance blocks 13.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0044] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.

[0045] In addition, any combination can be made between various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should also be regarded as the content disclosed by the present utility model.
