Description

Coal mine explosion-proof special type storage battery monorail hoist

The utility model belongs to the electric locomotive technical field, is the suspension type of underground mine use flameproof special type battery locomotive.

In technique known, owing to be subjected to the restriction of colliery underworkings condition, mine transport vehicle adopts ground narrow gage locomotive traction more.Along with the development of coal production, the down-hole transportation range is in continuous extension, and therefore, the underworkings transportation route needs enlarging thereupon.Especially to mine newly developed, the narrow hauling engine in tunnel can't pass through, and mining equipment need lean on manpower to carry, and has directly influenced the efficient of producing.Therefore, solve the target that this difficult problem has become those skilled in the art to capture.

The purpose of this utility model is a kind of coal mine explosion-proof special type storage battery monorail hoist of development, make it to be applicable to that the biogas that the down-hole narrow gage locomotive can't pass through is given prominence to, the tunnel is narrow, be difficult for the production scene that track is laid on ground, or the conveying of pit gear newly developed etc.

The utility model is achieved in that coal mine explosion-proof special type storage battery monorail hoist, comprises supply unit, control part, speed reduction gearing, drive wheel, driving setting device and carrying part.Be characterized in above-mentioned part crank connecting link being integral and fixing with suspension bracket separately; By being suspended on two sides of the monorail that I-beam section constitutes with the fixing scroll wheel of its suspension bracket.The electrical motor of this crane is positioned at the bottom of speed reduction gearing, and speed reduction gearing is twin shaft output, and its double output shaft is the axle drive shaft of two side drive wheel, and two drive wheels are by driving two sides that setting device is pressed on the monorail of I-beam section formation.Adopt the coal mine explosion-proof special type storage battery monorail hoist of said structure formation, can realize the purpose of invention of the present utility model.

Below in conjunction with accompanying drawing the utility model is described further:

The utility model is the suspension type of underground mine use flameproof special type battery locomotive.The control part of this monorail hoist is positioned at the front end of car, and it comprises master cock 7, the travel switch 8 of illuminating lamp 1, alarm bell 2 and the illuminating lamp of driver controller 3, resistor 4, comprehensive protector 5, volt meter 6 and this crane two sides.Electrical motor 9 be fixed in speed reduction gearing below, power supply box 11 is arranged on the back of speed reduction gearing, is 2 24V power supplys, can in parallel or single use.For guaranteeing power supply box 11 held stationary that is in operation, power supply box 11 2 ends hang on the power supply box suspension bracket 17 by shock absorber 22.12 for being positioned at the latch unitor of power supply box 11 sides, and 13 be connecting rod, is used for supply unit, control part, speed reduction gearing, the trucking department formation integral structure that links together that grades, and 14 be chain block, and 15 are the fixing suspension brackets partly of carrying, and 16 is scroll wheel.Mode of the present utility model is that the driver walks with garage, direct control department control handle.Its control principle is as follows: power supply E is through latch unitor QGL1, QGL2 and automatic switch DK or to driver controller HK (part 3) and resistor r (part 4) and traction motor D (part 9).By driver controller HK bar handle each contact is changed mutually control that monorail hoist starts, moves, stops, commutation etc.Handle has three positions." 0 ", commutation drum contact H ₁, H ₂, H ₃, H ₄Disconnect, monorail hoist is in the readiness that advances, and rotates governor handle, and monorail hoist can advance." backward " position, H at this moment ₃, H ₄Connect H ₁, H ₂Disconnect, monorail crane is in laggard readiness, rotates governor handle, and monorail hoist can retreat.The contact of each position of governor handle is organized closed situation and is seen the contact closure table.DK is the automatic switch in the gas cutoff instrument.DK closure under the normal circumstances.DK disconnects the monorail hoist power supply when gas density exceeds standard.But gas cutoff instrument surface is provided with the traffic lights monitor battery capacity, also is provided with button Q1 or Q2 in the monorail hoist rear and front end in addition, presses the button Q1 or Q2 when emergency situation, and automatic switch DK can disconnect, and makes monorail hoist out of service.Q3 is front and back luminous lamp switch (part 7).The utility model is source of AC and direct supply dual-purpose.Direct supply directly uses, and source of AC uses after adding conv.

The speed reduction gearing of this crane is made of upper and lower two part drop-gear boxs.Bottom drop-gear box 10 is worm screw, worm drive, and the lead angle of worm screw 28, worm gear 23 is from the locking angle, as long as outage can reach the parking requirement.Worm screw 28 simultaneously with two worm gears, 23 engagements of symmetric arrangement, the power of worm screw 28 is from the output shaft of the electrical motor 9 that is fixed in the speed reduction gearing bottom, by power being passed to the last drop-gear box 20 of two symmetric arrangement with the engagement of two worm gears 23.Go up drop-gear box 20 for two and be gear transmission, gear 24 is coaxial with worm gear 23, and the output shaft of gear 26 is an axle drive shaft 25, and drive wheel 19 is fixed on the axle drive shaft 25.27 are the fixing fixedly suspension bracket of speed reduction gearing.The characteristics of this speed reduction gearing are that speed ratio is big, the intensity height, and stable drive, safe and reliable, noise is little, is superior to other drive mechanism.

Drive wheel 19 is major parts of the utility model operation or parking, is made up of wheel carrier 29, pressing plate 31, rubber wheel 32, and allotment pad 30 is housed between pressing plate 31 and the wheel carrier 29, and rubber wheel 32 is loaded on outside the wheel hub that is made of pressing plate 31 and wheel carrier 29.Rubber wheel 32 usefulness polyurethane rubbers and steel wire compacting form, and are adjusted the elasticity of rubber wheel 32 by the gradient of wheel hub outer face.This structure is made handling ease, assembles easy to adjust.

Driving setting device 18 is made up of fixed mount 33, adjustment pull bar 37, pull bar 39, spring 40, steel rope 38 and adjustment nut.36 is packing ring.Fixed mount 33 is fixed in the last deceleration box place of two sides, pull bar 39 pocketed springs 40 of band pressing plate are connected with adjustment pull bar 37 by steel rope 38, adjust and fix with circular arc nut 35, nut 34, pull bar 39, adjustment pull bar 37 are individually fixed on the fixed mount 33 of two sides.Guarantee the normal operation of monorail hoist by the size of the gripping power between whole two drive wheels of this Adjustable structure.Under turning or uneven situation, two drive wheels can swing and prevent the generation of derailment occurring.When the fixing nut of adjusting pull bar 37 was adjusted to gripping power and is zero, under external force, drive wheel can be free to slide.Brake mode of the present utility model adopts the braking of spiral self-locking principle, promptly is in operation as long as outage is just stopped voluntarily.

The technical characterictic of this monorail hoist is as follows:
