br/> Overview of roller tank ears
Roller tank ears (coal safety certificate number:,,) are used for guide buffering of mine hoisting containers. The roller tank ears produced by our company have a number of patents (patent number:.), The technical performance of roller can ears is domestically leading.
The roller tank ears adopt advanced sealing technology to adapt to harsh environments such as water spray and coal dust. The installation of the wheel head of the roller tank adopts a three-locking structure to completely avoid the accident of the 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 roller tank earphone holder and swing frame are welded and formed from high-quality steel plates. The roller tank earphones are small in size, light in weight, and easy to install.
Roller tank ear structure
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, spring buffer devices, bases, etc. The spring buffer device in the roller tank ear is composed 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, etc.
Working principle of a roller tank ear
The roller tank ear buffer device adopts a butterfly spring group, which complies with the Ministry of Coal Industry Standard 3-. Its working principle is that the force of the roller is applied to the disc spring through the bracket, adjustment sleeve, adjustment screw, and disc spring shaft. The upper and lower movement of the shaft releases and compresses the disc spring group to achieve buffering.
The disc spring shaft of the 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 roller tank ear, the rubber layer of the roller is worn, and the roller is adjusted forward by adjusting the screw to move closer to 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.
Performance advantages of roller tank ears
. Good buffering performance and stable operation
. Long service life
3. Easy and reliable compensation adjustment after roller wear
. Installation, Easy to maintain.
Installation and use of roller tank ears
. Connect the roller tank ears to the lifter with a screw, adjust the position of the three roller tank ears relative to the tank channel, and ensure that the gap with the tank channel is consistent (the gap is about (), the axis center line is horizontal, the radial center line is perpendicular to the tank channel surface, and then the fixing bolts are tightened.
.According to the wear condition of the roller, the roller should be adjusted by loosening the screw lock nut and driving the screw to make the roller lean to the tank channel with a clearance of ~, and tighten the lock nut after adjustment.
