Abstract

The utility model relates to a Spring buffer idler, belonging to the technical field of a machinery conveyer. The utility model comprises an idler, a side bracket, a load bearing cross beam, buffer springs, etc., wherein, the number of the buffer springs is two, and the buffer springs are symmetrically arranged at the lower part of the idler and are formed into a definite angle with the load bearing cross beam. The utility model is suitable for conveying dispersed materials for metallurgy, a mine, coal, an electric power, a harbor, etc. The utility model has the advantages of simple structure, stable running, impact damage prevention, long service life, etc.

Description

The spring loaded impact idler

The utility model relates to the mechanical conveyor technical field, especially relates to having spring bearing housing in the roller conveyor, is installed in the roller configuring technical field on the framework.

Be used for metallurgy, the mine, coal, electric power, the belt conveyer of bulk material is carried at harbours etc., usually bigger at the impulsive force of blanking place material, cause adhesive tape, even the damage of support, for solving the shock problem at blanking place, belt conveyer is furnished with various impact idlers, as China's utility model patent: " a kind of belt conveyer shock absorber (patent No.: 96232399.3) ", it is that spring is installed in idler stand frame bottom, thereby plays buffer action, though this structure can reach the purpose of buffering preferably, but carrying roller for most of limits rack form, the essential bearing support crosspiece that increases could adapt to, and this will increase the cost of equipment.

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of buffering that can adapt to limit support carrying roller to be provided, can saving the spring loaded impact idler of cost again.

The technical solution of the utility model is such; A kind of spring loaded impact idler; comprise parts such as roller, limit support, load-bearing crossbeam, recoil spring; recoil spring has two groups; it is angled with the load-bearing crossbeam to be arranged on the roller below symmetrically; be coupled to limit support middle inside by spring shaft one end hinge, the other end and load-bearing crossbeam hinge connection are for the protective cradle power that is not hit is damaged; support connects employing hinge connection mode with the load-bearing crossbeam, the change fixed support is travel(l)ing rest.

Owing to adopted this version, realized the purpose that limit support carrying roller is installed recoil spring, do not need to increase the support crosspiece more simultaneously, saved cost, and also simple in structure, operate steadily, carrying roller prolongs service life.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing is a structural representation of the present utility model.

As seen from the figure, the utility model comprises roller 15, limit support 11, load-bearing crossbeam 4, recoil spring 13 parts such as grade, the limit support cuts with scissors connection with pin 1 mutually with support plate 2 on being welded on the load-bearing crossbeam, recoil spring has two groups, it is angled with the load-bearing crossbeam to be arranged on the roller below symmetrically, is coupled to limit support middle inside by spring shaft 12, one ends by pin 10 hinges, the other end mutually cuts with scissors connection with the load-bearing crossbeam with pin 9 by spring perch 5, there is pressing spring nut 3 on the spring top, and its end places on the spring perch, and spacing by stop screw 6.

15 fens middle roller of roller and limit roller, the limit roller links by limit axle 14, one ends and limit support, the axis 7 of the other end and middle roller with pin 8 mutually glue join; The roller faces of roller 15 adopts hot-cast glue, the middle roller face side of being thread form wherein, and the limit roller faces is left and right helix.

Claims
