Description
Technical field
Present invention is mainly applied to underground coal mine track Orbital Transport Systems, belong to coal production underground transport system auxiliary
Facility.
Background technique
In terms of development of auxiliary transport in coal mines at home, rail transport is increasingly paid attention to, wherein being developed based on track
Clamp rail rail system out, is also used on a large scale at home.
Track clamp rail rail system is divided into wire saws clamp rail rail system and ultromotivity clamp rail according to the difference of mode of traction
Rail system.
Wire saws clamp rail rail system mainly uses vertical slot just for running track, is turned using one group of continuous rope connection power
The mode of traction of disk and endless-rope towing vehicle.The system has following defects that
1, by continuous rope length limitation, general transportation lengths are within 2000 meters；
2, it is drawn using wirerope, there is disconnected rope risk, security risk is more；
3, continuous rope can only transport one time every time, cannot achieve more vehicle continuative transports, and freight volume is limited.
Ultromotivity clamp rail rail system is mainly used using clamp rail rack rails as the means of transportation of conveying track, and track is abnormal shape
There are vertical rack bar in rail, centre, by the continuous rotation of locomotive idler drive gear, drive the advance and retrogressing of locomotive.
Clamp rail rack locomotive, by hydraulic system, drives hydraulic motor, band mainly using anti-explosion diesel engine as power source at present
Motivation Chinese herbaceous peony into retrogressing.Brake apparatus is integrated in hydraulic motor rear portion, and brake action prevents hydraulic horse when braking is required
Up to rotation, parking is realized.In parking using same a set of mode of braking, parking braking is carried out.
Summary of the invention
It is a set of brake the invention solves parking braking and stopping brake, with the abrasion of brake(-holder) block, brake force meeting
Gradually decline, in long-term parking, there is the problem of security risk.
A kind of clamp rail rack locomotive parking braking system by parking braking block, parking oil cylinder one, disc spring one, disc spring two, is stayed
Vehicle oil cylinder two, adjustable throttling, two-position three way magnetic valve composition.
Disc spring one is set to the rodless cavity of parking oil cylinder one, and parking oil cylinder one is enable to stretch out cylinder rod in decompression；Disc spring
Two are set to two rod chamber of parking oil cylinder, and parking oil cylinder two is enable to shrink cylinder rod in decompression.
Parking braking block is connect with the cylinder rod of parking oil cylinder one and parking oil cylinder two respectively, is controlled by two oil cylinders
The location status of parking braking block.It is that on-position is still with rack gear disengaging that parking braking block, which is inserted among rack gear, in the present invention
Non-brake state.
Adjustable throttling is mounted on the hydraulic fluid port position of parking oil cylinder two, and oil inlet and oil return opening share one, pass through parking
The flow of oil cylinder two is adjusted, and realizes the movement speed of parking oil cylinder two, it is therefore an objective to the movement of parking oil cylinder two to be much slower than parking oil
Cylinder one.
The present invention is non-interference with stopping brake using independent a set of arrestment mechanism；It is realized and is stayed using rack gear latch mode
Vehicle braking, no friction are not worn, parking safety.
The present invention realizes that parking braking, no friction are not worn, brake force using rack gear latch mode compared with prior art
Greatly, safer；It is non-interference with stopping brake, form double brake protection.
Detailed description of the invention

Specific embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, a kind of clamp rail rack locomotive parking braking system, the parking braking system is installed on card
Below the carrying platform of rail rack locomotive 2, and pass through two pin shaft connections.
Parking braking system by parking braking block 6, parking oil cylinder 1, disc spring 1, disc spring 29, parking oil cylinder 2 10, can
Flow regulating valve 11, two-position three way magnetic valve 12 form.
Disc spring 1 is set to the rodless cavity of parking oil cylinder 1, and parking oil cylinder 1 is enable to stretch out cylinder rod in decompression；Dish
Spring 29 is set to 2 10 rod chamber of parking oil cylinder, and parking oil cylinder 2 10 is enable to shrink cylinder rod in decompression.
Parking braking block 6 is connect with the cylinder rod of parking oil cylinder 1 and parking oil cylinder 2 10 respectively, by two oil cylinders come
Control the location status of parking braking block 6.It is on-position or and rack gear that parking braking block 6, which is inserted among rack gear, in the present invention
Being detached from is non-brake state.
Adjustable throttling 11 is mounted on the hydraulic fluid port position of parking oil cylinder 2 10, oil inlet and oil return mouth only one, pass through parking oil
The flow of cylinder 2 10 is adjusted, and realizes the movement speed of parking oil cylinder 2 10, it is therefore an objective to the movement of parking oil cylinder 2 10 to be much slower than and be stayed
Vehicle oil cylinder 1.
When locomotive drive system work, driving fluted disc 3 normally rotates, and coke oven controller controls two-position three way magnetic valve 12
Movement makes hydraulic of locomotive system provide pressure to parking oil cylinder 1 and parking oil cylinder 2 10, and parking oil cylinder 1 is shunk, parking oil
Cylinder 2 10 stretches out, and the rack gear of control parking braking block 6 and clamp rail rack rails track 5 is detached from, and does not influence locomotive normal operation.
When locomotive drive system does not work, driving fluted disc 3 stops rotating, and coke oven controller is to two-position three way magnetic valve 12
Power-off, resets to it and unloads oil condition, and emptying, parking oil cylinder 1 are quickly stretched simultaneously for parking oil cylinder 1 and parking oil cylinder 2 10
Out, parking oil cylinder 2 10 is slowly shunk by adjustable throttling 11, and control parking braking block 6 being capable of quick insertion clamp rail rack rails rail
In the rack gear in road 5, locomotive is forbidden to be moved forward and backward.
