Description

Technical Field

[0001] This utility model belongs to the field of coal mine transportation technology, and relates to belt conveyors, specifically a quick repair kit for steel wire rope core conveyor belts. Background Technology

[0002] In coal mine transportation, belt conveyors play a crucial role. However, during actual transportation, protrusions from anchor bolts, pallets, coal retaining plates, damaged idlers, sharp stones, etc., can cause longitudinal tears in the operating belt. These longitudinal tears often lead to material spillage, which in turn halts transportation operations and causes significant economic losses to the coal mine.

[0003] Existing preventative measures mostly involve installing various protective devices on belt conveyors, but these still cannot completely prevent longitudinal tears. Therefore, we also need to focus on rapid belt repair, enabling quick repairs without affecting the conveyor's operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a quick repair kit for steel wire rope core conveyor belts, which can quickly repair longitudinal tears in conveyor belts without replacing the belt, without affecting normal production, and at low cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick repair kit for steel wire rope core conveyor belts, including an emergency self-locking clamp, galvanized iron wire, and cold repair adhesive; The emergency self-locking clip is used to temporarily clamp the longitudinal tear of the conveyor belt, that is, to fix several emergency self-locking clips at equal intervals along the longitudinal tear of the conveyor belt. The galvanized iron wire is used to replace the emergency self-locking clamp during repairs, that is, galvanized iron wire is used for transverse fixation at fixed intervals along the longitudinal tear of the conveyor belt; The cold-applied adhesive is applied to the longitudinal tear of the conveyor belt, and the galvanized iron wire is embedded in the cold-applied adhesive to ensure its lateral repair strength.

[0006] More preferably, the emergency self-locking clamp is a countersunk self-locking tooth structure with bolts symmetrically arranged on both sides, which are fixed to the longitudinal tear sides of the conveyor belt respectively.

[0007] More preferably, the emergency self-locking clamp includes an upper clamping plate and a lower clamping plate, and the two sides of the upper clamping plate and the lower clamping plate are clamped to the longitudinal tear of the conveyor belt by bolts and nuts; the upper clamping plate and / or the lower clamping plate are provided with a plurality of protrusions that can be embedded in the conveyor belt.

[0008] More preferably, the emergency self-locking clamp is clamped at a distance of 50cm at the longitudinal tear of the conveyor belt.

[0009] More preferably, the galvanized iron wires are arranged at intervals of 50 cm at the longitudinal tear points of the conveyor belt.

[0010] More preferably, the conveyor belt has a built-in steel wire rope core, and the distance between every two steel wire rope cores is 8mm.

[0011] More preferably, the galvanized iron wire is fixed to the steel wire rope core at 6cm on both sides of the longitudinal tear of the conveyor belt.

[0012] More preferably, the cold patch adhesive is a cold vulcanization layer repair adhesive.

[0013] More preferably, the working surface of the longitudinal tear of the conveyor belt is repaired with cold vulcanized layer adhesive with EP (polyester fiber) reinforcement, while the non-working surface is repaired with ordinary cold vulcanized layer adhesive.

[0014] The process of using this utility model: When a long-distance longitudinal tear of the conveyor belt occurs, first install two emergency self-locking clamps every 50cm to ensure that the longitudinally torn conveyor belt does not leak coal and to ensure normal production.

[0015] Then, repairs were carried out in stages during the downtime for maintenance. The emergency self-locking clips at the repair site were removed, and the longitudinal tear was ground, cleaned, coated with adhesive, and dried with a hot air gun. Galvanized iron wire was used to fix the two steel wire ropes 6cm apart on both sides of the longitudinal tear to replace the emergency self-locking clips.

[0016] Finally, apply cold-curing adhesive to the longitudinal tear of the conveyor belt. The working side of the longitudinal tear uses cold-curing adhesive with EP reinforcement, while the non-working side uses regular cold-curing adhesive, ensuring the cold-curing adhesive completely covers the galvanized wire.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This invention is easy to operate and has a simple process, achieving the repair effect without the need for large-scale vulcanization equipment.

[0018] Temporary repairs to longitudinal tears in the conveyor belt using emergency self-locking clamps ensure that the belt does not leak coal, can be started, and guarantees normal production. Furthermore, repairs can be made during maintenance time, allowing for immediate use after repairs, thus shortening downtime and improving work efficiency.

[0019] Longitudinal tears are repaired with cold-applied adhesive, which has the same service life as the original tape and will not delaminate or peel off from the original tape, thus eliminating the need for rework. Attached Figure Description

[0026] Please see Figures 1-2 A quick repair kit for steel wire rope conveyor belts includes an emergency self-locking clip 2, galvanized iron wire 3, and cold repair adhesive 4. Figure 3 As shown, the emergency self-locking clamp 2 has a countersunk self-locking tooth structure, with bolts 21 symmetrically arranged on both sides. These bolts 21 are used to clamp the conveyor belt 1 to both sides of the longitudinal tear. Galvanized iron wire 3 is used in place of the emergency self-locking clamp 2 during repairs; that is, galvanized iron wire 3 is used for transverse fixation at fixed intervals along the longitudinal tear of the conveyor belt 1. Cold repair adhesive 4 is applied to the longitudinal tear of the conveyor belt 1, covering the galvanized iron wire 3.

Figure 2 As shown in the figure, ensure that the longitudinally torn conveyor belt does not leak coal and guarantee normal production.

[0033] Then, repairs are carried out in segments during daily downtime maintenance. The emergency self-locking clip 2 at the repair site is removed, and the longitudinal tear is sanded, cleaned, coated with adhesive, and dried with a hot air gun. Galvanized iron wire 3 is used to fix and replace the emergency self-locking clip 2 between the two steel wire rope cores 11 6cm apart on both sides of the longitudinal tear (e.g.,...).
