Description

Mining spring hydraulic type safety brake

Technical field

The utility model relates to the braking technology field, is specifically related to a kind of mining spring hydraulic type safety brake.

Background technique

The trackless assistant conveyance vehicle that uses under the coal mine is in the middle of the environment of very severe, and operating mode is also more special, and the break of its use not only will have good braking ability; Also need possess reliable Security and resistance tocrocking; What the colliery underground vehicle used at present mainly is the break wet multi-disc, and it only realizes the hydraulic braking of oil bath type cooling and lubricating, does not also have compulsive-cooling safety type break; Break can produce great amount of heat energy when car brakeing; If the heat energy that break produces can not in time conduct or distribute, will make friction plate in the break overheated and the brake braking force square is descended, sharply shorten the working life of friction plate.

The model utility content

The purpose of the utility model is the mining spring hydraulic type safety brake that a kind of easy realization thrust disc brake off is provided and can in time dispels the heat.

In order to realize above function; The utility model adopts following technological scheme, and mining spring hydraulic type safety brake comprises left shell, central enclosure, right shell body and friction plate; Said left shell, central enclosure, right shell body connect successively; Said friction plate is installed on the central enclosure inboard, also comprises thrust disc, pressure spring and piston, and said thrust disc is between left shell and central enclosure; Said pressure spring is between left shell and thrust disc, in the piston groove of said piston between thrust disc and central enclosure.

Preferably, the mining spring hydraulic type safety brake of the utility model, said left shell, central enclosure, right shell body connect through bolt.

Preferably, the mining spring hydraulic type safety brake of the utility model, the width of said piston is less than the width of said piston groove.

Preferably, the mining spring hydraulic type safety brake of the utility model also comprises seal ring, and said seal ring is installed between left shell and the thrust disc.

Preferably, the mining spring hydraulic type safety brake of the utility model, said left shell exterior edge face is provided with cooling-oil outlet, air hole, cooling-oil inlet and retardation pressure mouth.

Preferably, the mining spring hydraulic type safety brake of the utility model is also installed wear indicator in the said cooling-oil outlet, and said wear indicator bottom contacts with thrust disc.

Preferably, the mining spring hydraulic type safety brake of the utility model, said friction plate comprises outside friction disc and interior friction plate, said outside friction disc and interior friction plate are at least a pair of.

Preferably, the mining spring hydraulic type safety brake of the utility model also comprises bearing, and said Bearing Installation is inboard in right shell body.

The utlity model has following beneficial effect:

1, solve on the present vehicle similar break take place easily owing to the thrust disc jam can't brake off and the piston seal life-span lack very much and the higher shortcoming of the too high manufacture cost that causes of requirement on machining accuracy;

2, use hydraulic pressure oil to promote piston and make thrust disc move brake off again, and conveniently dispel the heat, be prone to realize.

Description of drawings

Fig. 1 be the utility model plan view;

Fig. 2 is the A-A direction sectional view shown in Figure 1 of the utility model.

The practical implementation instance

To combine accompanying drawing and embodiment to come the utility model is done further detailed explanation below.

Shown in Fig. 1-2; The mining spring hydraulic type safety brake that the utility model provides; Comprise left shell 1, central enclosure 3, right shell body 4 and friction plate, said left shell 1, central enclosure 3, right shell body 4 connect successively, and said friction plate is installed on central enclosure 3 inboards; Also comprise thrust disc 2, pressure spring 7 and piston 9; Said thrust disc 2 is between left shell 1 and central enclosure 3, and said pressure spring 7 is between left shell 1 and thrust disc 2, in the piston groove 10 of said piston 9 between thrust disc 2 and central enclosure 3; Said left shell 1, central enclosure 3, right shell body 4 connect through bolt; The width of said piston 9 is less than the width of said piston groove 10; The utility model also comprises seal ring 8, and said seal ring 8 is installed between left shell 1 and the thrust disc 2; Said left shell 1 exterior edge face is provided with cooling-oil outlet 13, air hole 14, cooling-oil inlet 15 and retardation pressure mouth 16; In the said cooling-oil outlet 16 wear indicator 11 is installed also, said wear indicator 11 bottoms contact with thrust disc 2; Said friction plate comprises outside friction disc 5 and interior friction plate 6, and said outside friction disc 5 and interior friction plate 6 are at least a pair of; The utility model also comprises bearing 12, and said bearing 12 is installed on right shell body 4 inboards, is installed on the axle through bearing 12 at last.

The utility model is to realize braking through following mode like this and the brake off process:

One, braking process:

Give pressure from retardation pressure mouth 16, promote pressure spring 7 compressions, make thrust disc 2 under the effect of pressure spring 7, outside friction disc 5 is pressed together with interior friction plate 6 and right shell body 4 realize braking.

Two, brake off process:

The piston groove 10 of pressure oil in cooling-oil inlet 15 gets into the right side of pistons 9, make piston 9 promote thrust disc 2 to left movement to left movement, last pressure spring 7 and in making friction plate 6 combine and then brake off with outside friction disc 5 disengagings; Wherein, Air hole 14 is used for discharging the air of brake hydraulic line when debugging for the first time in system, friction disc wear indicator 11 is because the one of which end contacts with thrust disc 2; Be mainly used in the abrasion condition of indication outside friction disc 5 and interior friction plate 6, supply the maintenance man to confirm whether friction plate needs to change.

The foregoing description is the utility model preferred implementation; But the mode of execution of the utility model is not restricted to the described embodiments; Do not deviate from change, the modification done under spirit and the principle of the utility model, substitute, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
