Abstract
The utility model relates to a safety mine car which is applied to the track haulage of the inclined angle 8 DEG to 30 DEG of an inclined drift in a mine. The safety device of the safety mine car is composed of drive parts which are arranged on the bottom of the front end and the rear end of the mine car and a flexible buffer car block part which is arranged between tracks and matched with the drive parts. The drive parts are composed of a touching claw, a supporting spring, a drawing pull rod, etc. The flexible buffer car block part is composed of a flexible buffer car block sleeve and an absorption member. The safety device of the mine car changes original rigid impact into flexible impact in order to reduce the damage for devices.
Description
The utility model relates to a kind of safety type mine car, and particularly a kind of coal mine sloping lane that is applied to transports the safety type mine car of setting up a cover sport car safety device and constitute on mine car, belongs to the colliery transport field.
In the Coal Production process, sliding train in inclined lane is one of the most serious accident of mine transportation, and for resolving the safety problem of inclined gallery, mine transportation, constituent parts is developed multi-form anti-sport car protective device according to the actual conditions of oneself with suiting measures to local conditions.As mine inclined common car lug, hanging beam, the rod of keeping off a car, and the radar type catcher etc., but there are many shortcoming and defect in above alley stopping device in use, when being in operation, mine car take place to break off relations and when disconnected rope and sport car, the common rod of keeping off a car, stop, hanging beam exists the big shortcoming such as fragile equipment that contacts with rigidity of dumb, the impact force of action, though and the radar catcher changes the damage that the rigidity contact has alleviated equipment for flexible contact, but it is big to take up room, invest big expense height, fragile.
The purpose of this utility model is that a kind of mine car of design carries sport car safety device and a kind of safety type mine car with energy-absorbing function simple in structure.
Solution of the present utility model is achieved in that the sport car safety device of safety type mine car partly is made up of drive part and flexible buffer car bumper, and drive part is installed on the mine car, and the flexible buffer car bumper partly is installed between two conveying tracks; Drive part: support spring (4) is housed in support spring tube (3), support spring (4) is enclosed within on the drawing pull bar (2), the front end of drawing pull bar (2) is connected with slide block (13), mine car striking head (5) and slide block (13) and haulage cable (12) flexibly connect with mine car latch (6) pinning, the afterbody that bumps pawl (1) and drawing pull bar (2); The car bumper part is made up of fixing flexible car bumper cover (8) and the absorption cell in it.
For making drawing pull bar (2) that certain displacement be arranged, slide opening (7) should have certain length.
After making the mine car tune, also can transport safely, so drive part is respectively installed a cover in the bottom, rear and front end of mine car.
The change rigid shock is in flexible car bumper cover (8) absorption cell spring or rubber to be housed into the critical component of soft impulse.
The link (9) that is fixed on the flexible absorption cell is made of wire rope.
The utility model is installing two cover sport car safety devices on existing mine car, can be by manufacturer's direct production safety type mine car, also can on the basis of old mine car, transform and form, this apparatus structure is simple, flexible movements because of car bumper partly has buffering energy-absorbing, are soft impulse so this device becomes original rigid shock, significantly reduced the damaged condition of equipment, reached 100% through feasibility test link rate.
Fig. 1 is a structural representation of the present utility model.
Among the figure:
1---bumping pawl 2---drawing pull bar
3---spring strut 4---support spring
5---mine car striking head 6---mine car latch
The flexible car bumper cover of 7---slide openings 8---
9---link 10---rail
11---mine tram wheel 12---haulage cable
13---slide block
The contrast accompanying drawing further describes course of action below:
With threaded hole and slide block (13) pin-and-hole is placed in the mine car striking head (5), the front end of drawing pull bar (2) is screwed in the screwed hole of slide block (13), the slide opening (7) of the pin-and-hole of slide block (13) and mine car striking head (5) and haulage cable (12) mine car latch (6) pinning, when the safety type mine car under coal mine during the normal transport of inclined gallery winch haulage cable (12) by latch (6) pulling slide block (13) along slide opening (7) reach, drive and bump pawl (1) and make it upwards put certain altitude mine car can normally be moved along track thereby drive drawing pull bar (2) compression support spring (4).The afterbody that bumps pawl (1) and drawing pull bar (2) flexibly connects and is fixed on the tramcar chassis.
When unhook or rope-broken accident appear in mine car, drawing pull bar (2) resets to initial position under the effect of support spring (4), owing to arranged fixing flexible car bumper at a certain distance at interorbital, when mine car is gone to the position of fixing flexible car bumper, bump on the link (9) that pawl (1) just is suspended to car bumper automatically, force mine car to stop.
The flexible buffer car bumper is partly installed solid and reliable, and the direction of the position of installation and the angle of inclination and link (9) should make bumps pawl (1) and flexible car bumper and partly be in best link state, guarantees safety.
Claims (5)
1, the safety type mine car of inclined gallery transportation usefulness under a kind of coal mine, it is characterized in that: drive part is installed on the mine car, and the fixing flexible buffering car bumper part that is used with drive part is installed between two tracks; Drive part: support spring (4) is housed in support spring tube (3), support spring (4) is enclosed within on the drawing pull bar (2), the front end of drawing pull bar (2) is connected with slide block (13), with mine car latch (6) pinning mine car striking head (5) and slide block (13) and haulage cable (12), the afterbody that bumps pawl (1) and drawing pull bar (2) flexibly connects; The car bumper part is made up of fixing flexible car bumper cover (8) and the absorption cell in it.
