Description

The Pneumatic impact jumbolter
Technical field
The utility model relates to a kind of jumbolter, especially a kind of Pneumatic impact jumbolter.
Background technology
At present at the concrete characteristics of coal mining enterprise's economic situation and coal petrography, alternate heading bolt support, the monomer pneumatic rotary formula jumbolters that use more, the actuating unit of this kind rig is a kind of head of high-speed rotary, it passes through the output shaft outputting power by motor and deceleration device, drive drill bit and carry out rock-breaking drilling, advantage such as have rate of penetration height, consuming little energy, frame for movement is simple, work noise is low in the rotary cutting mode.Yet this pneumatic roof bolter that is rock-breaking drilling power in pure rotary cutting mode, still can not satisfy compressive strength and creep into work greater than the bolthole of the high sharp rock of 60MPa: because the rotary cutting performance of rig is often lost on the hard rock of this class, and very big to the wearing and tearing of self drill bit.Certainly often use monomer Pneumatic impact hammer drill to carry out the work of creeping into of bolthole at this situation people.
The connection of the whole each several part of existing monomer Pneumatic impact hammer drill, especially Pneumatic impact head section mechanism and following propulsive mechanism to be connected what adopt be flexibly connecting of a kind of articulated form, therefore in concrete anchor pole installation, use it beat meet head on or the horizontal hole effect fine; Yet often have head and top board out of plumb in the plate bolthole process of pinching, bolthole is beaten not straight problem.The operating mechanism of this kind hammer drill often is arranged on the head section mechanism simultaneously, and this just causes in the actual drilling operation, and operating mechanism can only be followed head section mechanism and be walked; Be equally in the plate bolthole process of pinching, head section mechanism constantly raises under the promotion of propulsive mechanism, and this brings difficulty just for constructor's manipulation operations mechanism.So whole anchor pole mounting process of this class Pneumatic impact hammer drill incompatibility.
Summary of the invention
The purpose of this utility model provides a kind of Pneumatic impact jumbolter, solves existing pneumatic rotary formula jumbolter above-mentioned and Pneumatic impact hammer drill and is carrying out deficiency and the defective of bolthole when creeping into operation.
In order to achieve the above object, the technical scheme of the utility model Pneumatic impact jumbolter is as follows: it comprises four parts of actuating unit, Connection Block, operating mechanism, propulsive mechanism of pneumatic roof bolter; Actuating unit, Connection Block and propulsive mechanism are taked to be rigidly connected from top to bottom successively, and operating mechanism is microscler control arm, and the one end is hinged on the Connection Block, and it is characterized by described actuating unit is a kind of Pneumatic impact head section mechanism.
The Pneumatic impact head section mechanism of this Pneumatic impact jumbolter can be the head section mechanism of existing Pneumatic impact hammer drill, comprises shell, rotating drill rod mechanism and drill steel fixed mechanism.It constitutes turning set, piston, rifle bar, ratchet mechanism rotating drill rod mechanism: turning set one end inside is milled with spline, matches with spline on the piston small end, is fixed with the bit shank cover in the other end; In the big end of piston rifle nut is housed, is tightened to one with piston, the spiral-shaped teeth of rifle bar small end inserts in the rifle nut, and the big end of rifle bar connects ratchet mechanism, and ratchet mechanism is fixed on the Connection Block.The drill steel fixed mechanism is connected bit shank and puts.
Built-in mechanism as existing Pneumatic impact hammer drill, spiral-shaped teeth on the rifle bar small end in this class rotating drill rod mechanism is left-handed, in the backward stroke of the piston process, because the folk prescription of ratchet mechanism has stoped the rotation of rifle bar to gyroscopic characteristics, so piston can turn clockwise with the left-handed shape tooth on the rifle bar.And jack panel in the anchor pole mounting process, needing sometimes, existing nut is the right-handed nut, and the nature that turns clockwise of piston is unfavorable for tightening of nut.
Secondly, present drill steel fixed mechanism is an a kind of rhampotheca mechanism, one end lock ring bit shank cover shell, and the other end is a double hook shape structure, radially clamps drill steel, string moves before and after it and vertically can allow.This mechanism head height that extended has relatively also increased head weight, tends in the practical operation to the plate bolthole of pinching controlling of head be brought certain influence.
At two above-mentioned problems, the head section mechanism of the utility model Pneumatic impact jumbolter improves: at first change the left-handed shape tooth on the rifle bar into dextrorotation, cause in the backward stroke of the piston to be rotated counterclockwise, thereby in the anchor pole mounting process, play the effect of jack panel with dextrorotation shape tooth.
Secondly, change original drill steel fixed mechanism into a kind of spring card slot mechanism, the architectural feature of this mechanism is, the bit shank cover is equipped with a circle hole of running through inside and outside wall near running-on part sustained height, and interior cinclides is less than outer cinclides; Embed steel ball from outer cinclides, steel ball has part to protrude interior cinclides, but can not pass.Bit shank cover outer wall has an annular cover, between annular cover inwall and bit shank cover outer wall cavity is arranged, and the cavity bottom is by spring junctor head mechanism shell; Under the spring nature, empty cavity position is higher than steel ball, and spring blocks steel ball, prevents and treats it and deviates from outer cinclides.During the dress drill steel, the presses annular cover, length of spring compressed, cavity descends, steel ball falls into, insert drill steel this moment, on the drill steel with bit shank cover in steel ball position sustained height be milled with the rectangular channel that cooperates with the steel ball projection, adjust slightly, unclamp the annular cover, spring is upspring steel ball is pushed in the hole, and steel ball embeds in the rectangular channel, and drill steel can only be slided along groove.This structure has shortened the head height relatively, has also alleviated head weight, in the actual plate bolthole process of pinching, head section mechanism can be controlled better.
Propulsive mechanism simultaneously of the present utility model adopts the glass fiber reinforced plastic supporting leg, and aluminium alloys supporting leg weight is lighter relatively, adapts to the plate bolthole operation of pinching in the anchor pole mounting process more.Yet the oil cylinder of glass fiber reinforced plastic supporting leg is bigger, and in the physical device, supporting leg thrust increases with the increase of oil cylinder, and excessive thrust often makes equipment lose impact capacity.Therefore, the utility model is also installed gas-pressure controlling valve on the gas circuit of glass fiber reinforced plastic supporting leg, is the propulsive mechanism decompression in real work.
The utility model Pneumatic impact jumbolter, owing to adopt the head section mechanism of impact type, compare with pneumatic rotary formula jumbolter, replace original pure rotary cutting to break the rock mode in the broken rock mode of impact rotating, make rig effectively remedy the shortcomings and deficiencies of Primordial Qi acting rotary jumbolter in compressive strength competent anchor pole installation work on the high sharp rock greater than 60MPa.The utility model is again the improvement to former pneumatic percussion hammer simultaneously, guaranteed that head section mechanism and propulsive mechanism are for being rigidly connected in the body, and the flexibly connecting of operating mechanism and other parts, optimized the position of operating mechanism, also bore bit fixed cover and drill steel and propulsive mechanism are optimized, make rig integral body more meet the anchor pole mounting process.
