Embodiment Construction

[0035] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0036] The hydraulically driven two-stage feed cylinder-guided symmetrically arranged rock bolt rig includes a support column assembly 1, a frame assembly 2, a carriage assembly 3, long and short feed cylinder assemblies, a chain multiplying mechanism 4, and a drill box assembly 5.

[0037] The carriage assembly includes a set of guide pillars I9 and another set of guide pillars II10 in a cylindrical structure, and the two sets of guide pillars are both composed of two symmetrically arranged guide pillars. The long and short feed oil cylinder assembly includes one short feed oil cylinder 8 and two long feed oil cylinders 7, the short feed oil cylinder 8 is arranged inside the carriage assembly, and the two long feed oil cylinders 7 are placed outside the carriage assembly and separated Symmetrically arranged on both sides. The support column a...

Abstract

The invention belongs to the technical field of the jumbolter, in particular to a hydraulic-driving two-level feeding cylinder-oriented symmetrically-arranged jumbolter. The hydraulic-driving two-level feeding cylinder-oriented symmetrically-arranged jumbolter solves the problem of the traditional jumbolter. The slide block assembly of the hydraulic-driving two-level feeding cylinder-oriented symmetrically-arranged jumbolter comprises two groups of guideposts of a cylindrical structure; a short feeding cylinder is arranged in the slide block assembly; two long feeding cylinders are arranged on the outer side of the slide block assembly; the back of a frame assembly is provided with a dovetail-groove structure in sliding fit with the dovetail-shaped guide rail of a sleeve; the front side of the frame assembly is connected with the guidepost I by a slide block guide block and forms sliding fit with the guidepost I; and a guide connecting plate is connected with the guidepost II and forms sliding fit with the guidepost II. According to the hydraulic-driving two-level feeding cylinder-oriented symmetrically-arranged jumbolter, the reliability of the jumbolter performance can be effectively improved, the anchoring and drilling efficiency is greatly improved, and the hydraulic-driving two-level feeding cylinder-oriented symmetrically-arranged jumbolter can be used for a smaller size space, has a better adaptability and is coal mine underground supporting equipment with high degree of automation and high reliability.

Description

technical field [0001] The invention belongs to the technical field of rock bolt rigs, and in particular relates to a hydraulically driven two-stage feed cylindrical guide symmetrically arranged rock bolt rig. Background technique [0002] Bolt support is a fast, safe and economical roadway support method. It is the representative of advanced support technology and the development direction of coal mine roadway technology. Bolt support has been widely used in major coal-producing countries abroad. my country's bolt support has been using a single hydraulic or pneumatic bolter to drill holes and manually install the bolt. This single-body rock bolt rig is generally composed of three parts: the rotating mechanism, the propulsion mechanism and the power device. It is operated with low automation, high labor intensity, poor safety, slow operation speed, and difficult to control the quality of anchor protection. defect. Contents of the invention [0003] In order to solve th...
