Overview of polyurethane roller tank ear
Jining Dongda Wang Can hotline
Polyurethane roller tank ear (Coal Safety Certificate No.: M, M, M, M ) are used as guide buffers for mine hoisting containers. The polyurethane roller tank ears produced by our company have multiple patents (patent number: .). The technical performance of polyurethane roller tank ears is domestically leading.
The polyurethane roller tank ears adopt advanced sealing technology to adapt to harsh environments such as water spray and coal dust. The lug head of the polyurethane roller tank is installed with a three-locking structure to completely avoid the accident of the wheel head falling off. The roller is cast with tetrahydrofuran epoxypropane 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 polyurethane roller can earphone holder and swing frame are welded and formed from high-quality steel plates. The polyurethane roller can ear is small in size, light in weight, and easy to install.

Polyurethane roller tank ear is a combined steel tank channel guide device independently developed by our company. Polyurethane roller tank ear is mainly composed of rollers and brackets , spring buffer device, base and other components. The spring buffer device in the polyurethane roller tank ear 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 tube, etc.
Polyurethane roller tank ear Performance advantages
Jining Dongda Wang Can Hotline
. Good buffering performance and stable operation
. Long service life
. Easy and reliable compensation adjustment after roller wear
. Easy to install and maintain.
Installation and use of polyurethane roller tank lugs
. Connect the polyurethane roller tank lugs to the lifter with a screw, and adjust the position of the three polyurethane roller tank lugs relative to the tank channel to ensure that the clearance between the polyurethane roller tank lugs and the tank channel is consistent. (The gap is about mm), the axis center line is horizontal, the radial center line is perpendicular to the tank channel surface, and then tighten the fixing bolts.
.According to the wear of the roller, the roller should be adjusted by loosening the screw locking nut and driving the screw to make the roller move toward the tank channel with a gap of ~mm. After adjustment, tighten the locking nut.

Working principle of polyurethane roller tank ears
The polyurethane roller tank ear buffer device adopts a butterfly spring group, which complies with the Ministry of Coal Industry Standard M. Its working principle is that the roller is stressed through the bracket, adjustment sleeve, adjustment screw, and disc spring The shaft is applied to the disc spring, and the up and down movement of the disc spring shaft releases and compresses the disc spring group to achieve buffering.
The disc spring shaft of the polyurethane roller tank ear moves up and down in the guide sleeve and the guide hole at the bottom of the cylinder. The lower end of the disc spring shaft is milled with a keyway, and the disc spring shaft cannot rotate due to the flat key at the bottom of the cylinder. 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.
During the operation of the polyurethane roller tank ear, the rubber layer of the roller is worn, and the roller is adjusted forward by the adjusting screw to 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. Drive the adjusting screw counterclockwise. The screw is unscrewed and the roller tilts forward to approach the tank channel. After adjustment, tighten the nut under the adjusting screw.
