Novel oil cylinder pressurizing and lifting device for blast hole drilling machine

Abstract

The invention discloses a novel oil cylinder pressurizing and lifting device for a blast hole drilling machine, and belongs to the field of mining machinery. The pressurizing and lifting device comprises a tower device and an oil cylinder arranged inside the tower device; the two ends of a piston rod are fixed to the tower device; a cylinder barrel slides up and down along the piston rod; pulley yokes at the two ends of the cylinder barrel are slidably connected with the tower device and provided with guide devices used for limiting the transverse rotation of the cylinder barrel; the two endsof a power head are connected with an upper steel wire rope and a lower steel wire rope correspondingly; the upper steel wire rope and the lower steel wire rope respectively bypass a upper driving wheel and a lower driving wheel and are fixed on the tower device; and the power head is driven to move up and down along the tower device through the stretching of the cylinder barrel. According to thenovel oil cylinder pressurizing and lifting device for the blast hole drilling machine, the up-and-down movement of the driving wheels is not limited by longitudinal space, so that the increasing of the diameter of the pulley is facilitated, and the service life of the steel wire ropes is prolonged; and the guide devices prevent the cylinder barrel from longitudinally deviating on the piston rod,so that the problems of shaking and instability in the drilling process are solved, and the system stability is improved.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and more specifically relates to a novel oil cylinder pressurizing lifting device for a blast hole drilling machine. Background technique [0002] In the prior art, the oil cylinder pressurization and lifting device usually fixes the cylinder barrel and uses hydraulic oil to drive the cylinder rod to slide. This kind of oil cylinder drive system has poor guidance and stability and is not suitable for large-scale mechanical equipment. [0003] For example, the patent application number: 2015210415129, the application date: December 15, 2015, and the name of the invention is: the pressurization and lifting device for the cylinder chain of the roller drilling rig. The top of the frame is provided with a first spring seat and a synchronous shaft assembly, the bottom of the drilling frame is provided with an oil cylinder seat, and an oil cylinder and a pulley are installed on the oil cylinder...

AI Technical Summary

Problems solved by technology

[0007] The new oil cylinder pressurized lifting device provided by the present invention is equipped with an upper drive wheel, a lower drive wheel and a double-acting double-piston rod oil cylinder inside the tower device. Long life, the pulley frame is equipped with a guiding device for limiting the lateral rotation of the cylinder, which can prevent the cylinder from longitudinally shifting when sliding on the piston rod, overcome the problems of vibration and instability during the drilling process of the drill pipe, and improve the stability of the system
