Abstract

The utility model belongs to a safety catcher for inclined shafts of mines, which is composed of a control box, a car-catching claw, a buffer, etc. The utility model is installed on the middle of the running track of a mine car; when the wire rope of the mine car breaks or the wire rope of the mine is out of control, the shaft of the car-catching claw is driven and controlled by a swinging rod mechanism to move and rotate, the car-catching claw disengages to slide downwards along the buffer under the action of a spring to enable the mine car to stop slowly to achieve the purpose of the automatic control of the mine car. Compared with the prior art, the utility model has the advantages of simple structure design, reasonable structure design, low cost, good car-catching effect, etc. The utility model is a requisite safety device for the inclined shafts of the mines.

Description

The automatic stop of inclined shaft tub

The utility model belongs to the mining machinery technical field, is specifically related to the automatic stop of a kind of inclined shaft tub in a kind of slope of mine transportation.

At present public mine car stop or stop device are owing to the restriction of structure, and engineering reliability is relatively poor, and safety factor is little.So be difficult to promote.

The purpose of this utility model provide a kind of simple in structure, that cost is low, flexibility is caught pawl is effective, buffer structure is installed in the automatic stop of inclined shaft tub that does not influence the normal operation of mine car in the middle of the track.

The utility model is to realize like this, the automatic stop of inclined shaft tub, comprise controller, catch the car pawl, it is characterized in that energy disperser passes through fixedly channel-section steel and road rail coupling, control box is contained in the energy disperser middle part, the energy disperser slide block is contained in the both sides groove of energy disperser, catches the car pawl by catching car pawl axle and the energy disperser slide block links, and catches car pawl axle by control again and control box links.In the both sides groove of energy disperser the wedge shape soft material is housed also, has reached the purpose that flexible buffer is caught the pawl car.

Dress fork, balance staff are equipped with the control slide block in the control box of the present utility model on the balance staff, and the slide block on the actuating spindle links to each other with fork by bearing pin, and front and back two cover swing-bar mechanisms utilize the time difference, have reached the purpose of catching the pawl sport car.

Description of drawings:

Fig. 1 is the main TV structure scheme drawing of the automatic stop of inclined shaft tub;

Fig. 2 is the plan structure scheme drawing of Fig. 1;

Fig. 3 is control box plan structure figure;

Fig. 4 is a wedge shape soft material diagrammatic sketch.

Label declaration:

1, control box 2, catch car pawl 3, energy disperser 4, fork 5, fork 6, control catch axletree 7, energy disperser slide block 8, wedge shape soft material 9, fixedly channel-section steel 10, spring 11, track 12, fixedly iron plate 13, fork 4 control slide blocks 14, fork 5 are controlled wedge block 15, actuating spindle 6 slide blocks 16, mobile pins 17, catch car pawl axle 18, are controlled and catch car pawl axle sleeve

With reference to the accompanying drawings embodiment is done further detailed description, the utility model is to prevent wire cable rupture and a kind of protection of installing and a kind of device of catching the pawl sport car automatically when being used for the transportation of mine inclined shaft, be fixed in the track 11, by control box 1, catch car pawl 2, energy disperser 3 is formed, unified being installed on the block plate 12, be connected as a single entity by hold down groove net 9 and track 11, and be fixed between the track of mine car operation, when sport car occurring, the mine car front axle is stirred fork 4, fork 5 (fork 4,5 distance limits, the time that permission is passed through can manually be adjusted) time shorten, fork 4 drives control and catches the 6 action rotations of car pawl axle, fork 4 drives control and catches car pawl axle 6, catches car pawl 2 and leans on the effect of spring 10 to upwarp, and can block the mine car rear axle and glide, the drive of mine car huge impact power is caught car pawl 2 and is glided along energy disperser 3 by slide block 7, contact with channel-section steel by wedge shape soft material (rubber), under the extruding of slide block 7, mine car is slowly stopped, thereby reach the effect of flexible braking.

The utility model compared with prior art has the structural design advantages of simple, and cost is low, it is effective etc. to catch car Advantage is a kind of safety means of slope indispensability.
