Description

Technical Field

[0001] The utility model relates to the technical field of mine material conveying equipment, in particular to a head wheel housing at the top of a mine bucket elevator which is convenient to open and close. Background Technique

[0002] For the TBG series plate chain type high-efficiency bucket elevator, the conveyed material is upgraded coal blocks with a particle diameter less than 10 mm, the lifting height is 30490 mm, the lifting speed is 36 m / min, the conveying capacity is 70 m³ / h, and it is fed by a screw conveyor, and the bottom is of a sealed design. During the existing use of the elevator, problems such as serious wear of the head wheel and loosening of the chain plates frequently occur, resulting in multiple accidents of the entire chain collapsing and breaking, causing damage to the components of the bucket elevator. Due to the long time required for accident repair, maintenance personnel must conduct inspections and maintenance continuously for 24 hours, and it is stipulated that the upper cover of the head wheel housing at the top of the bucket elevator should be opened at least twice a week to check the wear conditions of the head wheel and the chain plates. To prevent the chain of the bucket elevator from collapsing and to discover and eliminate problems before the components such as the head wheel and the chain plates deteriorate, and at the same time to reduce the labor intensity and improve the work efficiency, it is necessary to technically improve the method of opening the upper cover of the head wheel housing at the top of the bucket elevator to check the wear conditions of the head wheel and the chain plates. Since the continuity of production needs to be ensured, the maintenance personnel only have 30 minutes to conduct inspections, resulting in limited time for the maintenance personnel to open the upper cover of the head wheel housing at the top of the bucket elevator each time to check the wear conditions of the head wheel and the chain plates. Usually, the entire disassembly, installation and inspection work cannot be completed at one time and must be divided into two feeding cycles to complete. One feeding cycle is about 6 hours.

[0003] To overcome the above disadvantages, the traditional solution is that maintenance personnel need to prepare tools such as wrenches and chain hoists in advance. After the operator removes the twenty-eight fastening bolts on the upper cover of the head wheel cover plate at the top of the bucket elevator one by one with a wrench, and then cooperates with other operators to remove and lift the upper cover of the head wheel cover plate at the top of the bucket elevator with a chain hoist, and then check the head wheel, chain plate and chain bucket. After the inspection, the cover plate is reinstalled. However, during the operation of the equipment, this conventional method of removing the upper cover of the head wheel cover plate at the top of the bucket elevator takes too long and will affect the production efficiency, and wastes inspection time, manpower and material resources, greatly delaying the operation cycle of the equipment.
