Problems solved by technology

The existing upper and lower working platforms are mostly realized by the linkage mechanism, which is large in size and heavy in weight. Due to the limitation of its own structure, the lowest working surface of the upper and lower working platforms is mostly higher than the ground. The amount is large, the efficiency of drilling pipe up and down is low, and it is difficult to realize automation

Embodiment Construction

[0020] The preferred examples of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] A new type of automatic lifting device for drill pipes, comprising: a frame, a drill pipe lifting mechanism, a drill pipe bracket, and a drill pipe pushing mechanism, characterized in that: an oil cylinder seat is fixedly installed on the frame, and the lifting cylinder is fixedly installed on the cylinder block. The pulley is hinged with the piston rod of the lifting cylinder through the shaft, and the two ends of the lifting wire rope are connected with the frame and the support frame through the pin shaft, and connected with the pulley. The overturning oil cylinder is respectively hinged with the support frame and the drill pipe fork through the pin shaft, and t...

Abstract

The invention discloses an automatic lifting device for drill pipes. The automatic lifting device comprises a rack, a drill pipe lifting mechanism, a drill pipe bracket and a drill pipe pushing mechanism. By the aid of the automatic lifting device, the drill pipes can be pushed from one working platform to another working platform one by one. A cylinder barrel of a lifting cylinder is fixedly connected with the rack through a support; pulleys are connected with a piston rod of the drill pipe lifting cylinder through shaft hinging; two ends of each lifting steel wire rope are fixedly connected with a supporting frame and the rack respectively; turnover oil cylinders are hinged to the supporting frame and drill pipe forks respectively; the drill pipe forks are hinged to the supporting frame; and the supporting frame and the rack can slide relatively. According to the automatic lifting device for the drill pipes, the drill pipe lifting mechanism adopts a movable pulley structure, so that the lifting mechanism is effectively simplified, and the operation is simple. The drill pipe pushing mechanism adopts a link mechanism consisting of the oil cylinders and the drill pipe forks and is simple in structure, small in size and high in practicability.

Description

technical field [0001] The invention belongs to the field of drill rods for vehicle-mounted drilling rigs, and in particular relates to an automatic lifting device for drill rods. Background technique [0002] The tripping and unloading of drilling tools is an important link that affects the efficiency of drilling operations. At present, most vehicle-mounted drilling rigs use the elevator to lift the drill pipe first, and after the drill pipe is clamped by the slips, the task of loading and unloading the drill pipe is completed by means of the winch system and manual work. The platform of the rod loading device is relatively high. During the process of loading and unloading drill pipes, it is necessary to move the drill pipes onto or off the platform, which is difficult for manual labor. The upper and lower working platforms are used to go up and down the drill pipe, and assist the drill pipe to automatically enter or roll out of the drill pipe pallet. The existing upper a...
