Description
Technical Field
The utility model belongs to the maintenance is with the facility, specifically speaking is a repair dedicated maintenance platform of wire rope bearing roller.
Background
The loading building system is used for loading and transporting the bulk cargos, has the advantages of accurate measurement, balanced loading and high automation degree, is widely used in mines and ports, and has the following loading and transporting processes: the bulk goods on the loading building are metered and then placed in an open wagon carriage below the loading building, the carriage filled with the goods is pulled away from the loading position by a steel wire rope on a winch, and meanwhile, the next carriage is pulled to the loading position to continue the loading. The traction steel wire rope is horizontally arranged in a closed ring shape, the steel wire rope is connected with the part between the two carriages, the steel wire rope can droop to the ground under the action of self gravity and is abraded with the ground, in order to reduce the abrasion of the steel wire rope, a bracket is required to be arranged on the ground every 10 meters, and the carrier roller is arranged on the bracket, so that the steel wire rope passes through the carrier roller and drives the carrier roller to rotate. The total length of the steel wire rope is determined by the loading capacity of the whole loading building system, generally about 2000 meters, so that hundreds of carrier rollers are required to be installed.
The structure of the carrier roller is as shown in fig. 4, an inner sleeve 6.2 is supported on a shaft 6.5 of a supporting carrier roller 6 by a bearing 6.3, and a bearing gland 6.4 is buckled on the outer ends of two ends of the inner sleeve 6.2 for fixing; in order to prevent the steel wire rope from directly wearing the inner sleeve 6.2, the outer sleeve 6.1 is closely matched and arranged outside the inner sleeve 6.2, and in order to facilitate installation, disassembly and replacement, the outer sleeve 6.1 is generally equally divided into three sections which are sequentially arranged and sleeved on the outer surface of the inner sleeve 6.2.
When the support is used, the shaft heads at two ends of the shaft 6.5 are supported by the bracket placed on the ground, when the steel wire rope pulls the wagon compartment to move, the drooping part of the steel wire rope is in contact with the outer sleeve 6.1 of the carrier roller 6, and under the action of friction force, the steel wire rope drives the outer sleeve 6.1 and the inner sleeve 6.2 of the carrier roller 6 to rotate on the shaft 6.5 together.
When the winch works, a drooped steel wire rope rubs against an outer sleeve of a carrier roller, the outer sleeve is worn firstly because the hardness of the outer sleeve is lower than that of the steel wire rope, and a plurality of rugged grooves appear on the surface of the outer sleeve along with the increase of the running time; in addition, the surrounding environment for conveying goods mostly has more dust, sewage or sundries such as oil stain, and sometimes the carrier roller can still be soaked in the sewage, so that the carrier roller and the supporting bearing thereof are damaged seriously, and the whole fault rate of the carrier roller is high, so that the service life of the carrier roller is shortened. The loading and unloading work of the loading building is continuously carried out, a large amount of damages to the carrier roller can be caused, if the carrier roller is not repaired in time, the damaged carrier roller can damage the steel wire rope, the service life of the steel wire rope is shortened, the loss of raw materials is high, the normal production is influenced, and therefore the damaged carrier roller needs to be repaired in time for standby recycling.
The whole shape of the carrier roller is slender, the weight of each carrier roller is about 30 kilograms, and in order that an inner sleeve and an outer sleeve on the carrier roller cannot be separated in use, the inner sleeve and the outer sleeve are tightly matched. When the outer sleeve is worn and needs to be replaced, the long and thin carrier roller is not easy to erect, and the outer sleeve is very difficult to disassemble, so that the outer sleeve is taken down in a gas cutting mode in the prior art, fire is required to be started, and fuel gas is consumed; meanwhile, after the carrier roller is disassembled, one end head of the carrier roller is clamped on a bench vice, a new sleeve is knocked and installed, and the part is easy to damage due to unstable clamping and fixing and knocking and installation; moreover, when the bearing is replaced, because the space is narrow, the supporting roller clamped on the bench clamp is easy to damage other parts by hammering, the labor intensity is high, and the bearing replacing device is unsafe; in addition, the inner sleeve can be damaged if the outer sleeve is not well controlled during gas cutting, and the gas cutting is carried out in an open place with fire prevention measures, so that the gas cutting is very inconvenient.
The mode of dismouting bearing roller has not only occupied a large amount of manpower and materials, and maintenance efficiency is also very low, because the speed of maintenance can not keep up with its speed of damaging, can only purchase new finished product spare part in a large number to increase the occupation of fund, increased production and cost of maintenance.
Disclosure of Invention
The utility model aims to solve the technical problem that, when overcoming the bearing roller that current maintenance bearing wire rope used, it needs to use the mode fragile relevant part of gas cutting to change its overcoat, it is inconvenient to have fire prevention measure, it will press from both sides the bearing roller with the hammer beat to the bench vice with the installation overcoat to change the bearing, intensity of labour is big and dangerous, maintenance efficiency is low, the speed of damage can not be followed in the repair, many reserve spare parts occupy the fund volume greatly, shortcoming that cost of maintenance is high, a special maintenance platform of wire rope bearing roller is provided.
