Automatic electric energy storage pipe column conveying device for well servicing

Abstract

The invention relates to an automatic electric energy storage pipe column conveying device for well servicing. The automatic electric energy storage pipe column conveying device for well servicing comprises a lifting mechanism, wherein the lifting mechanism is fixed onto a base body; two ends of a feeding mechanism are respectively hinged with the lifting mechanism and the base body; a transfer gearbox is connected with the lifting mechanism and the feeding mechanism through two output shafts; a coiling block is connected onto the lifting mechanism and pulls the bottom end of a lifting frame to move through a flexible rope so as to jack the feeding mechanism; a gear rack mechanism is fixed onto the feeding mechanism; a gear set rotatably moves forwards on a rack set and is used for pushinga V-shaped groove to move parallelly along a conveying arm slideway; and the transfer gearbox is used for transmitting a motor drive force to the gear set and the coiling block. The automatic electric energy storage pipe column conveying device for well servicing provided by the invention is used for lifting a pipe column to a wellhead from the ground, and effectively solves the problems of hydraulic oil leakage, energy loss and low transmission efficiency of a pipe column conveying device based on hydraulic transmission, difficulty in working under the severe environments such as high temperature and low temperature, and idle work of the mechanism when the pipe column and an empty slot descend, so that the energy utilization rate and the transmission efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of new energy workover equipment, and in particular relates to an automatic delivery device for an electric energy storage pipe string for workover. Background technique [0002] New energy is currently most of the existing string conveying devices in my country adopt the hydraulic transmission method, but the transmission accuracy of the hydraulic transmission is not high due to the inevitable leakage of the relative moving surface, it is difficult to achieve further automation, and it is sensitive to oil temperature, so it is not suitable Work in harsh environments such as high and low temperature; there are along-line loss, local loss and leakage loss in the process of oil flow, and the transmission efficiency is low; and the hydraulic components are difficult to maintain and difficult to check when they fail. And after the pipe string is pulled up, the gravitational potential energy absorbed by the hydrau...
