Description

Technical Field

[0001] The utility model relates to the technical field of belt conveying, in particular to a steel core belt limiting claw. Background Art

[0002] In mining conditions, belts are often used for material transmission. Conveyor belts are mostly made of rubber, with a steel core or wire mesh as a structural reinforcement to improve tear and tensile resistance. Belt conveyors are mostly supported by V-shaped rollers. During the movement of the belt, the belt may deviate to the side of the roller due to the offset of the material support position and the limited rotation of the roller. After the above situation occurs, regardless of the circumstances, the belt can be naturally reset during the subsequent movement, but the deviation may also increase with the subsequent movement. In this case, it is necessary to stop the machine and reset the belt by manual dragging.

[0003] In the prior art, the methods for handling belt deviation have the following shortcomings: 1. Under mining conditions, the transportation of materials is continuous. If the machine is stopped to handle the belt deviation, it will affect the transportation of the ore and cause material accumulation inside the mine; 2. Since the installation location of the belt conveyor is usually a mine scene with uneven ground, there are certain safety hazards in manually dragging the belt to reset it. At the same time, the resetting operation takes a long time and is inconvenient to operate. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5As shown, the utility model provides a steel core belt limiting claw, including a lower clamping frame 1, an outer frame 5 and a belt limiting frame 3, wherein the outer frame 5 is an L-shaped structure, and one end is connected to the middle part of the lower clamping frame 1, and a top plate 4 is arranged on the top of the outer frame 5, and the belt limiting frame 3 is arranged between the top plate 4 and the lower clamping frame 1, and the upper end and the lower end thereof are respectively fixedly connected to the bottom of the top plate 4 and the top of the lower clamping frame 1; the lower clamping frame 1 is a straight channel steel, and the lower clamping frame 1 is formed with fixing holes penetrating the two side walls thereof. When installing, the lower clamping frame 1 can be first clamped above the bracket outside the belt, and then the bolts are inserted into the fixing holes to be fixed to the belt bracket;

[0027] The belt limiting frame 3 is composed of an intermediate frame 31, upper rollers 32, lower rollers 33 and side wheels 34. Among them, the upper rollers 32 and the lower rollers 33 are parallel to each other, and a belt夹缝 is formed between the upper rollers 32 and the lower rollers 33. The side wheels 34 are arranged at one end of the belt夹缝. During installation, the lower clamping frame 1 is installed on the support frame of the belt, and the edge of the belt is clamped in the belt夹缝, and the edge is in contact with the side wheels 34. The width of the belt夹缝 should not be greater than twice the thickness of the belt to prevent "flanging" of the belt edge. After such setting, when the belt deviates during the running process, the edge of the belt is pressed against by the side wheels 34, so as to prevent the deviation of the belt from expanding and achieve the effect of belt limiting. At the same time, through the rolling contact between the upper rollers 32, the lower rollers 33 and the side wheels 34 and the belt, hard scratching is also avoided, the damage of the belt edge can be avoided, and the service life of the belt is guaranteed. The intermediate frame 31 is in a "ji" shape structure, including an upper connecting rod 31a, a lower connecting rod 31b, an upper cross frame 31c, a lower cross frame 31e and a vertical frame 31d. Among them, the upper connecting rod 31a is connected to the top plate 4, the lower connecting rod 31b is connected to the lower clamping frame 1, one end of the upper cross frame 31c is connected to the upper connecting rod 31a, and the other end is connected to the vertical frame 31d; one end of the lower cross frame 31e is connected to the lower connecting rod 31b, and the other end is connected to the other end of the vertical frame 31d; an upper fixing plate 6 is arranged at the upper end of the upper connecting rod 31a, and the upper fixing plate 6 is connected to the top plate 4 by bolts; a lower fixing plate 2 is arranged at the lower end of the lower connecting rod 31b, and the lower fixing plate 2 is connected to the lower clamping frame 1 by bolts; the upper rollers 32 are installed on the upper cross frame 31c, the lower rollers 33 are installed on the lower cross frame 31e, and the side wheels 34 are installed on the vertical frame 31d; both the upper rollers 32 and the lower rollers 33 are in a cylindrical structure and have a length of 150 mm. The distance between the upper rollers 32 and the lower rollers 33 is not greater than 25 mm, and it can also be set according to the thickness of the belt, but the maximum distance should not exceed twice the thickness of the belt. A side groove 35 is formed on the side wheel 34. The side groove 35 is an annular groove formed circumferentially along the surface of the side wheel 34, and the side groove 35 faces the belt夹缝. After such setting, when the edge of the belt deviates along the belt夹缝 to the side wheel 34, the edge of the belt can enter the side groove 35, and through the limitation of the side groove 35, the upward warping or downward turning of its edge is prevented. The side groove 35 is an arc-shaped groove, and the width of the side groove 35 is equal to the width of the belt夹缝. The distance between the side wheel 34 and the upper rollers 32 and the lower rollers 33 is not greater than 5 mm. After the edge of the belt enters the side groove 35, since the inside of the side groove 35 is a uniform arc surface, the friction on the belt can be reduced on the premise of providing effective limitation and anti-folding protection for the edge of the belt.

[0028] By adopting the above structure, during the movement of the belt, its edge is stuck in the U-shaped limiting structure composed of the upper roller 32, the lower roller 33 and the side wheel 34. Under the obstruction of the side wheel 34, the displacement of the side of the belt can be effectively avoided, thereby improving the stability of the belt position; at the same time, the clamping of the belt edge by the upper roller 32 and the lower roller 33 can also avoid the "folding" that occurs after the belt edge and the side wheel 34 are tightened; when the belt is moved by manual dragging, the belt edge needs to be clamped with the help of mechanical tools, which may easily cause the belt to be damaged during the dragging process. In this solution, the upper roller 32, the lower roller 33 and the side wheel 34 are in rotational contact with the belt, thereby reducing the friction damage to the belt edge and ensuring the service life of the belt; the working process does not require manual intervention, thereby ensuring the stability of the belt position during conveying, reducing the downtime of belt adjustment, and does not require manual intervention, thereby improving safety.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
