Abstract
The utility model provides a hydraulic pressure brake shoe formula braking shuttle car, include: brake shoe, brake arm, piston rod, installing support, brake shoe are installed in one side of wheel, the brake shoe is fixed on the brake arm through the installation of round pin axle, and brake arm one end is installed on the piston rod, the other end is installed on the installing support, is equipped with the spring in the piston rod, is equipped with the cylinder liner outside the spring, the installing support installation is fixed on the frame. The utility model discloses with brake force direct action in wheel, make the holding brake reliability strengthen greatly, emergent events such as the disconnected rope of chance react rapidly, and the execution is reliable, strong adaptability can satisfy and includes in any place that fork department stops, it requires relative the reduction to lay orbital sleeper.
Description
Technical field
The utility model relates to the brake system technical field of mine assistant conveyance traction shuttle car, is 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.
Utility model content
The technical matters that the utility model solves is to provide a kind of hydraulic pressure brake shoe formula brake shuttle tram, to solve the problem proposed in above-mentioned background technology.
The technical matters that the utility model solves 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 beneficial effects of the utility model are: braking force is directly acted on wheel by the utility model, and stopping brake reliability is strengthened greatly, meet the accidents such as disconnected rope and are swift in response, and 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.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state schematic diagram of the present utility model.
In figure: 1, wheel; 2, brake shoe; 3, brake control lever; 4, piston rod; 5, cylinder sleeve; 6, spring; 7, mounting bracket; 8, bearing pin.
Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model 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 utility model 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 utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
