Description

A telescopic belt conveyor equipped with a belt idler mechanism

technical field

The utility model belongs to the field of logistics machinery, in particular to a telescopic belt conveyor provided with a belt idler mechanism.

Background technique

Telescopic belt conveyors are widely used in the express logistics industry. Due to the development of online shopping, a large amount of mail and parcels are produced in China every day. The telescopic machines in the sorting center work for a long time, and even run continuously for several days during the "Double Eleven" period. Belts wear out during everyday work, reducing machine life. The belt is an indispensable part of the telescopic machine. After the belt is installed, the equipment can transport the goods under the action of the prime mover, so as to load and unload the goods. The price of the belt is high. Once the belt is damaged, problems such as deviation may occur, and even cause damage to other parts of the equipment. In order to avoid the above situations, in addition to normal maintenance, it is necessary to strengthen the protection of the belt from the inside of the equipment.

Conventional belt conveyors use rollers and bed plates to support the belt, plus a tensioning roller to keep the belt taut to transport goods.

However, as the number of expansion joints increases, the internal structure of the telescopic machine becomes more complicated. And the belt is long, it will sag in different degrees. Once it has been running for a long time, the sag will be excessive, and the belt will continue to hit the frame of the telescopic machine during the rotation process, which will wear the belt and accelerate the damage of the equipment.

Specifically, it is that the tank chain 6 is set as follows: its widest face is perpendicular to the horizontal plane. The tank chain fixing plate 5 has a through hole, and the tank chain 6 is connected to the tank chain fixing plate 5 by bolts. The two-section traveling bridge frame 3 is fixed on the second expansion joint 4 through screw connection. The tank chain fixing plate 5 is welded on the second expansion joint 4 .

The belt conveyor described in the utility model is provided with five expansion joints, further improved, wherein the first to fourth joints adopt the above-mentioned idler mechanism 8, and the last joint adopts supporting rollers, and the supporting rollers are composed of The installation bearing 801, the rolling bearing 802, and the outer ring 803 are composed. Described mounting bearing 801 is fixed on the telescoping machine frame with positioning pin. The outer ring is used for tight fit with the rolling bearing. When the belt sags, the belt will rotate under the action of friction between it and the active rolling at the joint with the outer ring. The outer ring is installed on the bearing and can rotate with the belt. .

Beneficial effects: the belt is a necessary part of the telescopic belt conveyor, and the equipment cannot operate without it; at the same time, the price of the belt is very expensive, and once it is damaged, the cost will increase; in addition, the damage of the belt may also lead to the damage of other parts inside the equipment , Extend the service life of the belt, that is, extend the service life of the telescopic machine.
