The braking device comprises a brake driving device and a basic brake driven by the brake driving device, wherein, the brake driving device comprises an air compressor, an air reservoir, a hand brake control valve and a piston type spring brake air cylinder, all of which are connected with one another through pipelines in series; the piston type spring brake air cylinder has a non-brake spring side chamber connected with the hand brake control valve by a quick exhaust valve, a foot brake control valve is in series connection between a brake spring side chamber of the piston type spring brake air cylinder and the air reservoir. The utility model has the advantages of reasonable structure and flexible use; moreover, depending on the operating conditions such as roads and speeds, etc., a driver can conveniently adjust the braking force by the foot brake control valve, thereby reaching the aim of the effective brake.

Description

The two-way double acting air brake equipment of industrial-mineral electric locomotive
Technical field
The utility model relates to a kind of industrial-mineral electric locomotive brake equipment, specifically is the two-way double acting air brake equipment of a kind of industrial-mineral electric locomotive.
Background technology
Industrial-mineral electric locomotive air brake equipment in the past mainly adopts to wind braking and two kinds of brake mode of air draft braking.They have following shortcoming: 1, to wind braking when locomotive is not worked, brake block (basic drg) is thrown off with wheel, slides or slip car in order to prevent locomotive, must increase by one and overlap hand brake device; 2, the blast to wind braking and air draft braking is the fixed numbers of setting in advance, can't accomplish free adjustment at any time, causes the too big locking wheel of braking force deficiency or braking force easily, finally causes braking failure.
Summary of the invention
The utility model is not good for the braking effect that solves existing industrial-mineral electric locomotive brake equipment, the problem of other need complemental brake system, provides a kind of industrial-mineral electric locomotive two-way double acting air brake equipment.
The utility model is to adopt following technical scheme to realize: the two-way double acting air brake equipment of industrial-mineral electric locomotive, comprise brake transsmission device and the basic drg (being brake block) that drives by brake transsmission device, brake transsmission device comprises by pipeline and is series at together air compressor, the gas storage reservoir, hand braking control cock and piston type brake application by spring cylinder, piston type brake application by spring cylinder brakeless spring side cavity links to each other with hand braking control cock through quick exhaust valve, and piston type brake application by spring cylinder has between retarding spring side cavity and the gas storage reservoir and is in series with the foot brake control cock by the road.
Its basic functional principle is as follows: be pressed into pressurized air in the gas storage reservoir by air compressor, under the control of brake control valve, pass to each brake cylinder by the road, piston rod/push rod by piston type brake application by spring cylinder drives basic drg (being brake block), and locomotive is braked.The utility model adopts piston type brake application by spring cylinder to realize the air draft braking, before the normal operation of locomotive, need to alleviate, be about to hand braking control cock and pull the alleviation position, pressurized air did not have the spring side from piston type brake application by spring cylinder and entered this moment, promote piston and make length of spring compressed, piston rod then drives foundation brake rigging motion (being about to brake block opens), thereby locomotive is alleviated; During the locomotive normal brake application, hand brake valve is pulled retarder location, at this moment in the quick exhaust valve exhaust to atmosphere, alleviate by retarding spring along pipeline for the pressurized air in the brake cylinder, and piston rod then drives the foundation brake rigging motion, thereby makes locomotive brake.In addition, when locomotive during at last hill-start, at the locomotive relieved state, step on the foot brake valve, to brake cylinder compressed air pressure of retarding spring side is arranged, like this making a concerted effort just greater than the pressure of brake cylinder brakeless spring side of it and retarding spring, at this moment the quick exhaust valve that links to each other with brake cylinder brakeless spring side will be opened, make piston type brake application by spring cylinder brakeless spring side fast pressure relief, thereby make locomotive enter braking mode; Along with the rising of the locomotive tractive effort, slowly unclamp the foot brake valve, locomotive will be under situation about not sliding backward smooth starting; When locomotive during at steep gradient descending or emergency braking, hand braking control cock is pulled retarder location, this moment, the foundation brake rigging of locomotive was in braking mode, step on the foot brake control cock again, to brake cylinder compressed air pressure of retarding spring side is arranged,, improve braking effect to increase braking force.
Compared with prior art, the utility model adopts the energy brake pattern, when locomotive starts, and the inflation of piston type brake application by spring cylinder brakeless spring side, foundation brake rigging declutches, release of brake; In case the airline decompression, brake cylinder is exhaust immediately, and locomotive enters braking mode automatically, therefore cancels the manipulator brake equipment, and more convenient and safe and reliable more than the manipulator brake equipment; And with reference to the automobile brake principle, adopt the foot brake control cock to have the spring side to provide pressure controlled source of the gas to piston type brake application by spring cylinder, requirement when satisfying needs air brake in the locomotive driving, and because air pressure is adjustable with the foot brake control cock, guaranteed the soft of braking force, effectively avoided causing the danger of braking failure on rail level, and the phenomenon of car appears slipping when starting in the ramp in locomotive because of brake shoe locking wheel causes wheel to skid.Described air compressor, hand braking control cock, foot brake control cock, quick exhaust valve are modular, pneumatically powered components and parts; Piston type brake application by spring cylinder is existing known products, can be buied by brake cylinder professional production producer.
The utility model is rational in infrastructure, and effect is flexible, and the driver can by the size that the foot brake control cock is regulated braking force easily, reach the purpose of effective braking according to working conditions such as road, the speed of a motor vehicle.
Description of drawings
Fig. 1 is the structural principle scheme drawing of the utility model brake transsmission device;
Among the figure: the KYJ-air compressor; CQFG-gas storage reservoir; JZ-foot brake control cock; The hand braking control cock of SZ-; ZDQG-piston type brake application by spring cylinder; The PQ-quick exhaust valve; The pneumatic bigeminy part of ER-.
The specific embodiment
The two-way double acting air brake equipment of industrial-mineral electric locomotive, comprise brake transsmission device and the basic drg (being brake block) that drives by brake transsmission device, brake transsmission device comprises by pipeline and is series at together air compressor KYJ, gas storage reservoir CQFG, hand braking control cock SZ and piston type brake application by spring cylinder ZDQG, piston type brake application by spring cylinder ZDQG brakeless spring side cavity links to each other with hand braking control cock SZ through quick exhaust valve PQ, and piston type brake application by spring cylinder ZDQG has and is in series with foot brake control cock JZ between retarding spring side cavity and the gas storage reservoir by the road.During concrete enforcement, foot brake control cock JZ links to each other with gas storage reservoir CQFG through pneumatic bigeminy part ER with hand braking control cock SZ.
