Elevation type feeding work platform

Abstract

The invention discloses an elevation type feeding work platform. The elevation type feeding work platform comprises a stand, chain wheels, screws, shaft seats, a platform body, a speed reducer and a chain. Boards of an upper layer and a lower layer of the stand are supported and connected by tubular columns positioned at four corners, and each chain wheel capable of whirling is assembled at an upper opening end of the corresponding tubular column. The speed reducer is arranged in the stand, an outward side of the speed reducer is an input shaft end provided with a hand wheel, an output shaft is upward and is exposed out of the upper board of the stand, a chain wheel assembled on the output shaft of the speed reducer and the chain wheel connected to the upper opening end of each tubular column are positioned on the same plane, and all the chain wheels are in linkage via the chain. The platform body is placed above the stand, shaft seats are arranged at four corners of the bottom surface of the platform body and correspond to the tubular columns, the platform body is connected with the screws in a positioned manner by the shaft seats, the screws are matched with axial screw holes of the chain wheels at the upper opening ends of the four tubular columns, and therefore, a transmission structure in which the hand wheel controls the platform body to carry out fixed-axis ascending and descending along with the screws is formed. The height of the work platform is adjustable, so that the work platform is in butt joint with corollary equipment conveniently; and owing to barrier-free feeding, labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to a working platform, in particular, the invention relates to a feeding working platform, especially a lift-type feeding working platform for processing drill pipe joints. Background technique [0002] The drill pipe joint is the load-bearing and sealed connection part of the drill pipe. Usually, the drill pipe joint is made separately from the drill pipe, and finally the friction welding process is used to realize the butt joint. Due to different specifications, there are differences in the outer diameter and length of the drill pipe joint, and the largest difference in length is several tens of millimeters. During the production process, workers frequently load and unload drill pipe joints weighing several kilograms. If the position difference between the feeding table and the processing position is too large, it will inevitably increase the labor intensity of the workers. Continuous high-intensity labor will directly reduce pr...
