Description

Technical Field

[0001] The present invention relates to the technical field of heavy long-distance climbing transportation devices in mines, and specifically relates to a compensable tape repair clamping device and a manufacturing method thereof. Background Art

[0002] In mine transportation, belt conveyors are widely used for transporting ores, waste rocks, etc. As Figure 1 shown, it includes: a belt conveyor tail part 101, a belt conveyor head part 102, and a counterweight part 103;

[0003] 1. When the tape of a long-distance climbing belt conveyor reaches its service life limit, the tape needs to be replaced section by section. During the conventional construction process, the counterweight of the belt conveyor needs to be lifted. As Figure 2 shown: it includes: a counterweight box 1031, a counterweight deflecting roller 1032, and a deflecting roller 1033; after relaxing the belt, the front and rear ends of the tape to be bonded are pulled close and fixed on the belt conveyor support, and then the front and rear ends of the tape are placed between two steel profiles (angle steel or channel steel) serving as the upper pressing plate and the lower pressing plate, and bolts are arranged on both sides of the two steel profiles for connection. Through the bolt connection, the upper and lower steel profiles clamp the tape for fastening. As Figures 3-4 shown, it includes: an upper steel profile 201, a lower steel profile 202, a connecting bolt A 203, a nut A 204, and a tape 205. When clamping the tape in this way, due to the pre-tightening force of the bolts at both ends of the fixture, the fixture will produce bending deformation and the middle part will bulge. In addition, the wear of the middle part of the tape is larger than that of the edge part, resulting in a gap e1 - e2 between the fixture and the middle part of the tape, and the actual clamping contact area is insufficient, easily causing a sliding phenomenon between the tape and the fixture, resulting in misalignment and skew of the tape docking interface, and causing the tape to deviate during production; at the same time, to prevent sliding, the operator will increase the pre-tightening force of the bolts, and at this time, the edge corners of the steel profile fixture will damage the tape.

[0004] 2. During the process of transportation production, it is also often necessary to repair and replace some deflecting rollers of the belt conveyor. Conventionally, when replacing the roller, the counterweight of the belt conveyor needs to be lifted. After relaxing the belt, the tape at both ends of the roller is pulled against each other with a steel profile fixture, so that the tape at the roller is relaxed to a certain extent, and then fixed to the belt conveyor support with a hoist, and then the roller is replaced. The pulling force required when pulling the tape against each other is very large, so there will also be situations such as sliding between the fixture and the tape. Summary of the Invention

[0005] The purpose of the present invention is to provide a compensable tape repair clamping device and its manufacturing method. By setting a floating splint and using adjustment screws to locally adjust the uneven local wear of the compensable tape and the gap generated by the deformation of the fixture, sufficient clamping area is ensured, the constancy of the pre-tightening force is effectively guaranteed, and it is safe and effective to solve the problems proposed in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] Furthermore, it also includes a steel wire rope, an electric hoist, upper rollers and brackets, lower rollers and a belt conveyor bracket; the belt conveyor bracket is used to support and connect the tape, and the tape includes an upper belt and a lower belt; multiple groups of upper rollers and brackets are supported and connected below the upper belt; multiple groups of lower rollers are connected below the lower belt; the clamping body is respectively clamped on the upper belt and the lower belt; the steel wire rope is sleeved at both ends of the clamping body, and the other end of the steel wire rope is connected to the electric hoist, and the electric hoist is fixedly connected to the belt conveyor bracket through the steel wire rope.

[0009] Furthermore, a gap is left between the flange of the floating splint and the flange of the upper fixture to compensate for the gap e1 - e2 generated by deformation.

[0010] The present invention provides another technical solution: a manufacturing method of a compensable tape repair clamping device, including the following steps:

[0011] S1: When clamping the upper belt, 1 - 2 groups of upper rollers and brackets can be removed first, then the upper fixture is placed above the upper belt, and the lower fixture is placed below the upper belt;

[0013] S3: After preliminarily tightening the connecting bolts B at both ends to sufficient torque for the second time, then preliminarily tighten the adjusting screws in the middle, and then tighten the lock nut and nut B.

[0014] S4: Put steel wire ropes on both ends of the upper fixture and the lower fixture, and fix them on the belt conveyor support with an electric hoist and the steel wire ropes.

[0015] S5: When clamping the lower belt, it is not necessary to remove the upper idlers and their supports. Place the upper fixture below the lower belt and the lower fixture above the lower belt.

[0016] S6: Pass the connecting bolts B through the holes at both ends of the upper fixture and the lower fixture. After preliminarily tightening the connecting bolts B until there is no gap between the two side edges of the lower belt and the fixture, evenly tighten the adjusting screws in the middle of the upper fixture from the middle to both sides until there is no gap in the middle.
