Description
Technical field
The invention belongs to mining equipment, particularly relate to the stopping means that a kind of rotary drill hoisting mechanism moves up and down.
Background technology
Rotary drill is surface mining heavy drill equipment, its hoisting mechanism is by drilling cramp, pedestal, dc motor, reducer, main clutch, pneumatic tube brake, closed chain, gear and tooth bar are formed, pedestal establishes slew gear, be connected with drilling tool under slew gear, slew gear is installed a pair jockey sprocket, a pair deep trouth hinge wheel and a pair pinion, deep trouth hinge wheel and pinion are contained on a transverse axis, power is transmitted by dc motor, through reducer, main clutch, pneumatic tube brake, closed chain, deep trouth hinge wheel arrives and is positioned on the pinion at transverse axis two ends, pinion rolls along the tooth bar on stand both sides, slew gear drives hoisting mechanism to move up and down along stand.The stopping means of current rotary drill hoisting mechanism is made up of the travel switch and the collision block be arranged on slew gear being arranged on drilling cramp top, collision block impact stroke switch, thus the motion controlling hoisting mechanism.The defect existed is rotary drill hoisting mechanism promoting continually, in decentralization process, because effect of inertia often offside situation occurs, collision block and travel switch are rigid contact, very easily cause travel switch to damage malfunctioning, and then easily there is security incident, travel switch is short for application life, and replacement frequency is high, and spare parts consumption is large, maintenance time is long, inefficiency, increases cost of production, affects mine and normally produce; In addition the drilling cramp top that is arranged on of the travel switch of rotary drill stopping means, installs and maintenance very inconvenience, there is potential safety hazard.
Summary of the invention
In order to overcome the defect of prior art, the object of the present invention is to provide a kind of rotary drill hoisting mechanism taper sleeve type stopping means, extend travel switch application life, reduce travel switch and change number of times, reduce spare parts consumption, reduce cost of production, avoid causing security incident to occur, eliminate safe hidden trouble.
Rotary drill hoisting mechanism taper sleeve type stopping means, comprises drilling cramp and pedestal, is characterized in that this device is made up of upper fixed seat, lower fixed seat, wire rope, overcoat, inner sleeve and travel switch, and described drilling cramp top and bottom establish upper fixed seat, lower fixed seat respectively; Wire rope is vertically arranged in inner sleeve, and upper end is fixed on upper fixed seat, and lower end is fixed on lower fixed seat, and inner sleeve bottom at least establishes a trip bolt to be fixed on wire rope; Coat suit is on interior cover, and travel switch is placed in outer putting, and its movable contact roller is connected mutually with inner sleeve, and during travel switch work, put in travel switch movable contact roller is resisted against, when not working, roller is away from inner sleeve.
The present invention improves further, and fixed seat, lower fixed seat are channel-section steel, and it establishes installing hole, and upper and lower mounting hole site is on same vertical curve, and wire rope is placed in installing hole, and head is fixed by wire clips, ensures that wire rope is vertical.
The present invention improves further, and described inner sleeve is connected and composed by guide pipe and conical tube, and guide pipe is consistent with conical tube internal diameter, and the tapering of the conical tube conical surface is 55 °-65 °, and flange is established in conical tube lower end, and flange prolongs it and at least establishes a screw in the radial direction.
The present invention improves further, described overcoat is made up of cylinder case, annulus landing slab and plate produced from coils, through hole is established in cylinder case upper end, aperture is slightly larger than guide pipe external diameter, the internal diameter of cylinder case is less than inner sleeve flange outside diameter, it is highly greater than the height of conical tube, and cylinder case lower end connects annulus landing slab; Annulus landing slab establishes travel switch, and travel switch pair of rollers flexible case should establish a breach, and movable contact roller stretches into inside case by breach; Plate produced from coils is welded in below landing slab, and plate produced from coils internal diameter is greater than flange outside diameter, and when travel switch closes, annulus landing slab droops on flange, prevents cylinder case wearing and tearing conical tube, ensures travel switch operating sensitivity; The height of plate produced from coils is greater than the height of the thickness+conical tube of flange, when the roller of travel switch leave conical tube domatic time, the pedestal of hoisting mechanism is not yet against to inner sleeve flange.
The present invention improves further, and rubber pad is established in the position of described wire rope corresponding flange screw, and the head of trip bolt holds out against rubber pad, increases the frictional force of wire rope and interior inner room, and when preventing hoisting mechanism from declining, overcoat impacts excessive to inner sleeve, causes inner sleeve landing.
Overcoat is encountered when the pedestal of hoisting mechanism moves upward, overcoat is driven to move upward along the guide pipe of inner sleeve, travel switch movable contact roller slides along the conical tube face of inner sleeve, the movable contact connecting rod of travel switch extends, the internal switch contact of travel switch disconnects power-off, the stop motion of rotary drill hoisting mechanism, when hoisting mechanism moves downward, overcoat drives travel switch to move downward along the guide pipe of inner sleeve due to self gravitation, the movable contact roller of travel switch also slides along the conical tube face of inner sleeve, the movable contact roller of travel switch is in impaction state (i.e. contraction state), the movable contact connecting rod of travel switch shortens, the internal switch closing of contact is energized, the control loop that rotary drill hoisting mechanism moves upward is connected, for moving upward of hoisting mechanism is next time ready.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; This device adopts the cooperation of inner-outer sleeve, the rigid contact of original stopping means is become flexible contact, greatly extend travel switch application life, improve the safety and reliability that rotary drill runs, reduce and change travel switch number of times, easy for installation, avoid causing security incident to occur, eliminate safe hidden trouble, reduce travel switch spare parts consumption simultaneously, reduce cost of production.
