Description
Technical Field
The utility model belongs to the technical field of hanging tiles of screw conveyors, and particularly relates to a quick-release structure of hanging tiles of screw conveyors.
Background
The hanging tile in the main stream screw conveyor in the market can be divided into a hanging tile main body, a spline housing I and a spline housing II. The hanging tile main body consists of a spline shaft, a clamp spring I, a hanging tile rack, a clamp spring II, a copper sleeve and other parts. The spline shaft is inserted into a copper sleeve in the hanging tile frame, and can only circumferentially rotate in the hanging tile main body under the limit of the clamp spring I and the clamp spring II. The spline housing I and the spline housing II are matched with the spline shaft in a large clearance, and the spline housing I and the spline housing II can freely axially slide on the spline shaft.
Commonly used layout designs for screw conveyors are typically "stabbed" assemblies. The screw conveyor with the common conveying distance of more than 6 meters is provided with hanging tiles in the middle section so as to ensure that the hinge shaft of the inlet section and the hinge shaft of the outlet section cannot be subjected to large deflection change, thereby avoiding the hidden trouble that the hinge shaft scrapes the wall plate of the screw conveyor casing. However, the copper sleeve in the hanging tile main body is easy to wear, and the service life of the copper sleeve which works for 12 hours daily is only 6-10 months under the condition that the oil injection maintenance requirement reaches the standard. It can be seen that the difficulty of the replacement of the copper bush directly affects the operation and maintenance costs of the screw conveyor.
The replacement sequence of hanging tiles in the existing screw conveyor is as follows: disassembling the combined piece I, and disassembling the spiral conveyor from the ash bucket of the dust remover to be placed on the ground; unscrewing the closing part V, withdrawing the packing sealing cover and the graphite packing from the spiral conveyor shell, unscrewing the closing part IV between the outlet section twisting shaft and the tail shaft; the fastening piece III is disassembled, and then the bearing seat and the tail shaft are horizontally pulled out and disassembled; the spline housing is fully welded with a sleeve on the outlet section winch shaft, and the outlet section winch shaft is horizontally pulled out from the spline shaft on the hanging tile main body to be detached; unscrewing the combined part II, cushioning the hinge shaft of the inlet section to stabilize the hinge shaft, and horizontally dragging the hanging tile main body out of the hinge shaft of the inlet section through the spline housing II fully welded by the sleeve; and disassembling the hanging tile main body and replacing the copper bush.
The work load of the tile hanging process is extremely large, and the associated parts are extremely large. The replacement and assembly work of the hanging tile copper sleeve are extremely unfavorable, the production progress is further influenced, and the operation cost of the equipment system is greatly improved.
