Description

Crawler crane is used in narrow low tunnel

Technical field

The present invention relates to a kind of narrow low tunnel in tunnel that is used under the coal mine and use crawler crane, belong to mechanical equipment technical field.

Background technology

Under mine, in the installation process, there are many equipment in installation process, need sling or under the state of slinging, move a segment distance at present.The ground hoisting crane of tradition can be accomplished sling weight and translation easily, but because the tunnel is narrow, the traveling difficulty, traditional ground crane-car can not use under the coal mine.The general method that adopts is to use simple lifting tools such as gin pole, chain block, and labor strength is big, efficient is low.Since the eighties in 20th century, also once used equipment such as chamber hoisting crane, lifting machinery under the mine, but these equipment can not extend and move because of stationkeeping and can not satisfy the downhole anti-explosion requirement with the tunnel.Though also occurred some down-hole hoisting cranes now, all have the drawback of poor effect, in narrow and low tunnel voluntarily the walking, aspect such as translation weight, the big quality weight of slinging does not also have good terms of settlement on a large scale.

Summary of the invention

The crawler crane that the purpose of this invention is to provide narrow low tunnel under a kind of coal mine, the labour intensity when installing to reduce underground equipment is increased work efficiency.

The present invention adopts following technical scheme to realize: crawler crane is used in narrow low tunnel; Comprise the traveling gear on the vehicle main body; Traveling gear is made up of crawler body and hydraulic efficiency pressure system thereof; Be fixed with turn table and rigid platfor on the crawler body, turn table is provided with rotary motor, preceding counterweight, hydraulic telescopic arm and operator's compartment; Hydraulic telescopic arm inside is provided with telescopic oil cylinder, is provided with amplitude oil cylinder between hydraulic telescopic arm and the turn table; Hydraulic telescopic arm links to each other with turn table on the crawler body through hinge and amplitude oil cylinder, and amplitude oil cylinder is controlled the downward tilt of telescopic boom, and rotary motor is controlled the telescopic boom sway; Suspension hook is fixed on through adapter plate on the hydraulic telescopic arm of car front end, and the up-and-down movement of suspension hook is through the work of getting off on the hydraulic telescopic arm; Vehicle front is equipped with forklift; Preceding counterweight is fixed on the rotary table with rotary motor turns round with hydraulic telescopic arm.

Vehicle main body top is provided with firedamp sensor.When gas density reached specified value in the air, firedamp sensor received behind the signal in the operator's station alarm display, and drives the relay movement in the closing appliance, cuts off the electricity supply, and crawler vehicle quits work; The operator's compartment internal fixation has the gas alarming of containing operation displayed platform, and the operator's compartment top is provided with the anti-guar plate of pounding of detouchable.

On the rigid platfor of the postmedian of car, be fixed with anti-explosion diesel unit, water supply tank, gas tank, fuel tank, hydraulic reservoir, hydraulic efficiency pressure system and back counterweight.

The telescopic boom front end is installed hydraulic pressure portion additional device, reserves in the automobile hydraulic system and can handle the fluid control valve that is installed at arm front end additional work device hydraulic actuator.

Crawler width is 58.8% of an overall width, makes under narrow vehicle body state, to have less specific pressure over the ground.

Hydraulic telescopic arm adopts rigid telescopic oil pipe and telescopic oil cylinder fixedly to guarantee to be synchronized with the movement.

Working process of the present invention: narrow low tunnel advances to the work place with crawler crane by pithead voluntarily; Or deliver to the down-hole from well head; Operating personal is into the car in the work of driver behavior platform control crawler body then; Crawler body drives hoisting crane and advances, thereby in the mine tunnel, walks, and forklift is rooted out the little obstacle of the road of advancing simultaneously.When running to working position, operating personal passes through the fluid control valve modulated pressure telescopic boom of operator's station, the weight thereby sling in the position of control suspension hook.Thereby can make the remote hoisting heavy of flexible translation of arm hydraulic telescopic arm through control to telescopic oil cylinder; When hoisting heavy, can control the upper and lower, left and right translation of arm hydraulic telescopic arm through rotary motor and amplitude oil cylinder, thereby enlarge the height and the position of hoisting heavy.Preceding counterweight guarantees the hoisting crane balance of arm hydraulic telescopic arm when diverse location is sling weight along with the arm hydraulic telescopic arm turns round together; The solid word of back counterweight is motionless, has improved the ability that side direction is sling weight.Lifting telescopic boom front end can be installed the hydraulic pressure additional device, reserved in the automobile hydraulic system and can handle the fluid control valve that is installed at arm front end additional work device hydraulic actuator, so this hoisting crane installs different accessories additional and just possesses multifunctionality.

Advantage of the present invention is following:

1. crawler type of the present invention tunnel draining pump truck vehicle width is narrow, highly low, is suitable for hoisting heavy in the tunnel narrow, short under mine, while and the lifting of can walking.Crawler width is 58.8% of an overall width, makes under the narrow vehicle body state, also has less specific pressure over the ground;

2. narrow low tunnel of the present invention is equipped with perching knife with the crawler crane vehicle front, and carrying capacity is strong;

3. crawler type of the present invention tunnel draining pump truck has designed telescopic Hydraulic jip and rotary table, can control the weight level of slinging, left and right, upper and lower moving by the fluid control valve on operator's station during lifting.The lifting telescopic boom can about 90 degree work, luffing angle be-10 the degree to+30 the degree, maximum lifting weight is 5 tons;

4. narrow low tunnel of the present invention without steel rope type winch, is that the motion with arm comes work with the motion of suspension hook in the crawler crane, and simple in structure, the weight lifting can be lifted by crane in limited height with a simple accessory;

5. narrow low tunnel of the present invention adopts two counterbalance design with crawler crane, guarantees the lifting balance when diverse location is sling weight;

6. narrow low tunnel of the present invention adopts coal peace type anti-explosion diesel unit driving engine with crawler crane, and has gas alarming to show on the operator's station, has guaranteed downhole operations personnel's safety;
