Abstract

The utility model relates to a device which conveys finished product steel pipes and semi-product steel pipes into a material collecting basket, which comprises crank and slide bar mechanisms; each crank and slide bar mechanism is composed of a crank 1 which is driven to rotate by a motor and a slide bar 2 which is driven to rotate by a pin shaft 6 at the other end of the crank 1. The device is composed of at least two crank and slide bar mechanisms which are arranged in the direction of conveying steel pipes in parallel. The upper and front end of the slide bar 2 is provided with a salient position block 5. The steel pipes on a bracket for a sloping bench can be raised up in parallel and conveyed to the bottom of a material bracket. The pin shaft 6 on the crank 1 can slide upward and downward in a slide-way 4 below the slide bar. The multi-layer accumulation of the steel pipes can be realized. With the device, the height of a free falling body of the steel pipes is reduced; the average peak value of noise pulse is caused to be reduced by about 10 dB.

Description

A kind of slide crank rod-type steel pipe noise reduction feedway

The utility model relates to a kind of steel pipe feedway, especially in the steel pipe's production process finished product, half-blank is transported in the collection charging basket.

At present, in the steel pipe's production process, generally adopt steel pipe on sloping skid, freely to tumble in the charging basket, in the free-falling body process of steel pipe, the violent collision being taken place between steel pipe and steel pipe, steel pipe and the charging basket, continuously make a noise, seriously influences the healthy of operator.

The purpose of this utility model is to obtain a kind of slide crank rod-type steel pipe feedway, can from sloping skid steel pipe be transported to the charging basket bottom, reduces the height of steel pipe free-falling body, with the noise that reduces to send because of bump between the steel pipe.

For achieving the above object, the utility model is achieved in that

A kind of slide crank rod-type steel pipe noise reduction feedway, it comprises: by the crank 1 of driven by motor rotation and the slide crank linkage be made up of the slide bar 2 that the bearing pin 6 of the crank other end drives swings, this device is made up of at least two above-mentioned slide crank linkages along the parallel placement of steel pipe throughput direction, front end has the locating piece 5 of projection above the slide bar 2, and slide bar 2 rear portions have chute 9 to slide on rest pin.

The chute 4 of above-below direction is arranged at slide bar 2 bottoms, and the bearing pin 6 on the crank 1 slides in chute 9.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Accompanying drawing is the utility model slide crank rod-type steel pipe transport conveyor constructions scheme drawing.

Referring to accompanying drawing, this device is installed in sloping skid 7 and steel pipe is collected between the charging basket 8, when steel pipe stops after sloping skid 7 tumbles baffle plate 10 places, at this moment, crank 1 by driven by motor upwards rotates, and drives slide bar 2 and swings forward, and the locating piece of slide bar 2 front ends 5 lifts steel pipe, this device is made up of at least two said mechanism along the parallel placement of steel pipe throughput direction, steel pipe can be lifted abreast to send into and collect the charging basket bottom; Crank 1 is to lower swing then, and the chute 9 at slide bar 2 rear portions slides backward along rest pin 3, drives slide bar 2 and withdraws from beyond the charging basket position, prepares to prop up next root steel pipe.

When steel pipe is stacked into certain altitude, because the chute 4 of an above-below direction is arranged at slide bar 2 bottoms, the bearing pin 6 of crank 1 can slide up and down in chute, can guarantee that a back steel pipe is below slide bar 2 front end height are deposited on the steel pipe, along with crank 1 continues revolution, slide bar 2 is extracted out from two steel pipes, reaches multilayer steel pipe windrow.

Adopt device of the present utility model steel pipe can be delivered to the charging basket bottom from sloping skid, reduce the height of steel pipe free-falling body, reduce the noise that bump produces between the steel pipe, steel pipe noise pulse average peak descends about 10 decibels.
