Abstract
The invention provides a hydraulic brake block type brake shuttle car. The brake shuttle car comprises a brake block, a brake arm, a piston rod and a mounting bracket, wherein the brake block is mounted at one side of wheels, and is fixedly mounted on the brake arm through a pin shaft; one end of the brake arm is mounted on the piston rod, and the other end is mounted on the mounting bracket; a spring is arranged in the piston rod; a cylinder jacket is arranged at the outer side of the spring; and the mounting bracket is fixedly mounted on the frame. Braking force is directly acted on the wheels, so that the parking brake reliability is greatly promoted, the response to such emergencies as rope break is fast, and the performance is reliable; and the hydraulic brake block type brake shuttle car is strong in adaptability, can be parked in any place including a turnout, and relatively reduces the paving requirements of rail sleepers.
Description
Technical field
The present invention relates to the brake system technical field of mine assistant conveyance traction shuttle car, be specially a kind of hydraulic pressure brake shoe formula brake shuttle tram.
Background technology
SQ-1200 endless rope series tractor be coal mine down-hole tunnel with a kind of common rail transportation device of rope traction, and tractor truck must have braking function, prevents from slipping because of wire cable rupture the generation of the accident such as car, sport car.
The brake system of existing shuttle car generally adopts inserting grab, and wirerope-winding, on capstan drum, by the annulus on slotting pawl, is mentioned slotting pawl, fag end is fixed by vehicle frame.When steel rope surprisingly ruptures, retaining pawl for want of rope support and fall, between the sleeper being stuck in track, realize stopping-down.But in fact, when unexpected generation, this kind of brake response is blunt, and slotting pawl can not fall in time or slotting pawl falls and fully effectively can not block sleeper, and car brakeing is stopped and be there is very large potential safety hazard.
Summary of the invention
Technical matters solved by the invention is to provide a kind of hydraulic pressure brake shoe formula brake shuttle tram, to solve the problem proposed in above-mentioned background technology.
Technical matters solved by the invention realizes by the following technical solutions: hydraulic pressure brake shoe formula brake shuttle tram, comprise: brake shoe, brake control lever, piston rod, mounting bracket, brake shoe is arranged on the side of wheel, described brake shoe is fixed on brake control lever by bearing pin, brake control lever one end is installed on the piston rod, the other end is arranged on mounting bracket, be provided with spring in piston rod, spring outwards is provided with cylinder sleeve, and described mounting bracket is fixed on vehicle frame.
Described cylinder sleeve is fixed on vehicle frame.
Described brake shoe and wheel concentric circles are arranged.
Compared with prior art, the invention has the beneficial effects as follows: braking force is directly acted on wheel by the present invention, stopping brake reliability is strengthened greatly, meet the accidents such as disconnected rope and be swift in response, perform reliable; Strong adaptability, can meet and comprise the parking of turnout place anywhere; The sleeper of track is laid and requires relatively to reduce.

Detailed description of the invention
In order to make actualizing technology means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
As shown in Figure 1 and Figure 2, hydraulic pressure brake shoe formula brake shuttle tram, comprise: brake shoe 2, brake control lever 3, piston rod 4, mounting bracket 7, brake shoe 2 is arranged on the side of wheel 1, described brake shoe 2 is fixed on brake control lever 3 by bearing pin 8, and brake control lever 3 one end is arranged on piston rod 4, the other end is arranged on mounting bracket 7, is provided with spring 6 in piston rod 4, be provided with cylinder sleeve 5 outside spring 6, described mounting bracket 7 is fixed on vehicle frame.
Described cylinder sleeve 5 is fixed on vehicle frame.
Described brake shoe 2 is arranged with wheel 1 concentric circles.
Hydraulic pressure brake shoe formula brake shuttle tram is arranged in the left and right sides of shuttle car vehicle frame, and every side is each a set of, is installed between the two-wheeled of front and back, and often cover comprises:; Two brake shoes, 2, two brake control levers, 3, two piston rods, 4, cylinder sleeve, 5, spring 6, a set of mounting bracket 7, six bearing pins 8.
Concrete enforcement is that brake shoe 2 bearing pin 8 on the left side and a brake control lever 3 are coupled together, and is then also connected by bearing pin 8 grade with mounting bracket 7 lower end of brake control lever 3.The fitting process of right-hand member brake shoe and brake control lever is identical with left side program.After brake block components has assembled, mounting bracket is connected and fixed on the vehicle frame of tractor truck by bolt by shown position.Again the cylinder sleeve 5 of oil cylinder is also fixed on the vehicle frame of tractor truck by shown position.Finally the piston rod 4 of oil cylinder is connected by bearing pin 8 with the upper end hole of brake control lever.This hydraulic pressure brake shoe formula brake equipment is totally two covers, controls former and later two wheels of the left and right sides of brake shuttle tram respectively.
Principle of work of the present invention is: suppress oiling by piston rod 4 end of the hydraulic parts such as hydraulic oil pipe to oil cylinder simultaneously, when oil pressure reaches the spring force overcoming spring 6, piston rod 4 drives brake control lever 3 to middle displacement, and brake shoe leaves wheel, the state that declutches of the normal work in place.When braking car and needing braking, operated by the valve of hydraulic efficiency pressure system, the fluid in oil cylinder is discharged by hydraulic fluid port under the effect of spring 6, and piston rod 4 is protruding, and promote brake control lever 3 and move laterally, wheel is close to by brake shoe, vehicle place braking mode.During reset, then operate by the above-mentioned feed liquor that carries out.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
