Structural principle of roller tank ear
The roller tank ear is a combined steel tank channel guide device independently developed by our company. The roller tank ear is mainly composed of rollers, brackets, It is composed of spring buffer device, base, etc. The spring buffer device consists of an adjusting sleeve, an adjusting screw, a nut, a disc spring shaft, a guide sleeve, a coupling cap, a set screw, a disc spring, a flat key, a cylinder barrel, etc.
The roller tank ear buffer device adopts a disc spring group. Its working principle is that the roller is released by the vehicle through the bracket, adjustment sleeve, adjustment screw, and disc spring shaft. The up and down movement of the disc spring shaft is released and the disc spring group is compressed. buffer.
The disc spring shaft moves up and down in the guide sleeve and the guide hole at the bottom of the cylinder barrel. There is a key milled on the lower end of the disc spring shaft. The disc spring shaft cannot rotate due to the flat key at the bottom of the cylinder barrel. The guide sleeve is screwed into the cylinder and presses the disc spring shaft so that the shoulder of the disc spring shaft presses the disc spring. For safety and reliability, the guide sleeve is locked with a cap, and drilled and tapped together with the cylinder barrel, and set screws are used. Fasten.
Due to the rubber layer of the roller being worn during operation, the roller is adjusted by adjusting the screw to tilt forward and approach the tank channel. One end of the adjusting screw has a left-hand thread and the other end has a right-hand thread. Screw in the adjusting sleeve and disc spring shaft respectively. When adjusting, loosen the nut under the adjusting screw and turn the adjusting screw counterclockwise. The screw is screwed out and the roller tilts forward to approach the tank channel. After adjustment, tighten the nut under the adjustment lever.
Installation of roller tank ears
Connect the roller tank ears to the lifting container with bolts. Adjust the position of the three roller tank ears relative to the tank channel to ensure that the clearance with the tank channel is consistent and the axis center line is horizontal. The radial centerline is perpendicular to the tank channel surface, and then the fixing bolts are tightened.
Use of roller tank ears
According to the wear of the roller, the roller should be adjusted by loosening the screw lock nut, turning the screw to make the roller lean to the tank channel, the gap is ~, and tighten the lock after adjustment Tighten the nut.
Regular inspections should be made on whether the top screw, nut, shaft end nut and other fasteners of the roller spindle are tightened, whether the roller is loose, whether the roller is running and worn, and whether the swing frame is deformed. If any abnormality is found, check The reason can be explained and it can be used after recovery.
If you find quality problems, you are not allowed to disassemble it yourself. You should negotiate with the dealer for repair or return, or you can contact our company directly.
Roller tank ears
Series of roller tank ears (Coal Safety Certificate No.:,,) are used for guide buffering of lifting containers in mines. The roller tank ears produced by our company have a number of patents (Patent No.:.) , the technical performance is domestically leading.
This product adopts advanced sealing technology and is suitable for harsh environments such as water spray and coal dust. The wheel head installation adopts a three-locking structure to completely avoid the accident of wheel head falling off. The roller is cast with tetrahydrofuran-propylene oxide copolyether polyurethane, which has the advantages of high elasticity, tear resistance, water resistance, and oil resistance. The roller wear compensation adjustment adopts left-hand and right-hand screws, and the adjustment is quick and convenient. The machine base and swing frame are welded and formed from high-quality steel plates, which are small in size, light in weight and easy to install.
