e. lapping: laying a layer of clean plastic film on the surface of the lower heating plate, laying a layer of glue stock to enable the glue stock to be matched with the inclined plane of the joint, overlapping steel wire ropes of the same type according to the regulation requirement, coating the glue stock to ensure that the glue stock is uniformly coated and distributed, laying the glue stock, laying a layer of plastic film on the glue stock, and completing the overlapping of the local broken wires of the steel wire rope core conveying belt;
f. after the belt is completely adhered, vulcanizing and hot-repairing the cut belt crack; the hydraulic press plate, the pressure transmission plate and the vulcanizing plate are placed on the basis of the center line of the working surface of the hydraulic press plate, the pressure transmission plate and the vulcanizing plate, and are aligned with the center line of the steel wire rope core conveying belt, and vulcanization work is completed after vulcanization and heating;
g. after all the work is finished, the machine is tested and operated under the state of different frequencies, and the operation condition of the rubber belt conveyor is observed through an online monitor.
Furthermore, the vulcanization heating temperature in the step f is 140-145 ℃, and the vulcanization heating time is 8 hours.
Compared with the prior art, the invention has the following beneficial effects:
the belt at the broken wire part of the steel wire rope is treated by adopting a local treatment method on the premise of not replacing the whole belt, the broken steel wire rope is lapped, and the vulcanization hot patching treatment is carried out on the broken steel wire rope adhesive tape by adopting a vulcanization hot patching process, so that the total time consumption is short. And a vulcanization hot patching process is adopted, so that the cost required for replacing the whole belt once is reduced. The production cost is reduced, and the economic benefit is improved.
Detailed Description
The present invention is further illustrated by the following specific examples.
Example 1
The embodiment takes the coal industry company of the new year of the plastic of the new year of the university and the coal mine group, as an example:
the mine in the coal industry of Xiaoyu has a perfect main transportation system, and particularly, the main shaft belt conveyor has the function of carrying out up-and-down transportation in the well, and is the most important link in the transportation system. The main well conveyer belt uses a steel wire rope core flame-retardant adhesive tape, the model ST/S3150, the bandwidth is 1.4 m, the total length of the upper part and the lower part is 1440 m, 89 inner-connection steel wire ropes are transversely arranged, and the conveyer belt needs to be replaced when the transverse broken wire of the steel wire ropes exceeds 10 percent according to the coal mine safety regulation.
The method is used for repairing the conveying belt of the rubber belt conveyor as follows:
a. and observing the specific position of the conveyor belt where the wire rope breakage exceeds 10% by using an online monitor.
b. The broken wire position is used as the center, the position with the distance of about 0.9 meter between the two sides is fixed by the clamping plate, the belt (conveying belt) is loosened and tensioned, and the running of the conveying belt is prevented.
c. And cutting the belt at the broken wire position by using a belt detaching knife until the steel wire rope at the broken wire position is exposed.
d. Manufacturing a connector: cutting all the net wires of each belt head, scraping off the adhesive on the surface, polishing the steel wire rope core conveying belt at the root of the steel wire rope into a slope with the width of about 100mm by using an angle grinder, then polishing the steel wire rope core conveying belt outwards along the slope for 150mm, removing the surface of the original steel wire rope core conveying belt and polishing the steel wire rope core conveying belt. And cleaning the steel wire and the polished surface by using 120# gasoline.
e. Lapping: firstly, a layer of clean plastic film is laid on the surface of the lower heating plate, and then a layer of glue material is laid, so that the glue material is matched with the inclined surface of the joint. And (3) overlapping steel wire ropes of the same type according to the regulation requirement, and coating the adhesive cement to ensure that the adhesive cement is uniformly coated and distributed. And spreading a layer of plastic film on the rubber material to complete the lapping of the local broken wires of the steel wire rope core conveying belt.
f. And after the belt is completely adhered, performing vulcanization hot patching on the cut belt crack. The hydraulic press plate, the pressure transmission plate and the vulcanizing plate are placed on the basis of the center line of the working surface of the hydraulic press plate, the pressure transmission plate and the vulcanizing plate, and the center line of the hydraulic press plate, the pressure transmission plate and the vulcanizing plate is aligned with the center line of the steel wire rope core conveying belt. And vulcanizing and heating to 140-145 ℃ and working for 8 hours to finish the vulcanizing work.
g. After all work is finished, the test run is carried out under the state of different frequencies, the observation is carried out through the on-line monitoring instrument, and the normal operation is found within one week without any influence.
The belt at the broken part of the steel wire rope is treated by adopting a local method, about 1 day is needed, about 2 days is needed for replacing the whole belt, 1 day is saved, about 1 ten thousand tons of coal are mostly transported for the coal industry company of Shugao coal Xiaoyu in the Shuzhou, and about 250 ten thousand yuan of profit is mostly obtained.
The vulcanization hot patching process is adopted, and the cost of belt material purchase for the Shuozhou Shuaizao Xiaoyu coal industry company is saved by about 1440 multiplied by 400=576000 yuan every time the whole belt is replaced.
