Description
The utility model belongs to a kind of mine car in the mine shaft conveyance system, is specifically related to a kind of mine car dead-man's device that is installed on the mine car underframe.
At present, known automobile, train and other vehicle as transportation means, its brake portion generally has oil brake, brake device.And in mine shaft conveyance system, the mine car row of traction such as electric locomotive, diesel locomotive only are equipped with brake gear on hauling engine, are pulled the mine car that locomotive draws, and generally all do not have brake gear.Particularly under coal mine in the main haulage roadway, be pulled the mine car row of locomotive traction, because mine car is not installed brake gear, so the deceleration of operating permutation mine car and braking are the brakings by the brake gear of hauling engine itself, the force of inertia of buffering permutation mine car is realized.Because the braking of mine car row is to adopt aforesaid way, so travelling speed and transport capacity all are restricted, the mine transportation is the sustainer that mine is produced.Along with the development and the raising of mine capacity, mine transportation problem at present as the mine car row of the main transportation means of mine and the above-mentioned brake mode of mine car thereof, is one of problem that influences the mine capacity raising particularly.
The purpose of this utility model is for being pulled mine car and the mine car row thereof that locomotive draws in the mine shaft conveyance system, a kind of mine car dead-man's device being provided, in order to solve the operating quick short range braking problem of mine car.
Below in conjunction with accompanying drawing the mine car dead-man's device is described in detail.
Accompanying drawing 1 is mounted in the constructional drawing of facing of mine car dead-man's device on the mine car underframe;
Accompanying drawing 2 is mounted in the plan structure figure of the mine car dead-man's device on the mine car underframe;
Accompanying drawing 3 is constructionals drawing of engaging and disengaging gear (4), buffer gear (9);
Accompanying drawing 4 is square section scheme drawings of self-locking runback detent mechanism (16).
From accompanying drawing 1, accompanying drawing 2, this mine car dead-man's device is installed on the mine car underframe.It comprises by a stressed probe (1), engaging and disengaging gear (4), buffer gear (9), rotating shaft (12), bearing support (13), brake shoe (14), self-locking runback detent mechanism (16), collision mechanism (20) etc. and forming.
The stressed probe (1) of this mine car dead-man's device is mounted in a connecting rod on the mine car underframe, and the first half of stressed probe (1) passes the device of meeting and discussing (21), and device one segment distance of meeting and discussing in advance.General run of thins lower stress probe (1) keeps meeting and discussing in advance device one segment distance under the application force of spring (2).When the effect that is subjected to force of inertia, when bumping between car and the car, the suffered force of inertia of stressed probe (1) promptly passes to engaging and disengaging gear (4).
Engaging and disengaging gear (4) is made up of thrust block (3), force block (6) and thrust pin (5), and an end of engaging and disengaging gear (4) is connected with probe (1) tail end, and the other end is connected with buffer gear (9).Thrust pin (5) is fixed in the upright opening of thrust block (3) tail end.The thrust pin two ends are installed in the L shaped groove of the last one group of symmetry of force block (6).Thrust block (3) can only be made axial motion in the groove of force block (6).Force block (6) both can axially move, and can move up and down again.This piece can change the position of thrust pin (5) in L shaped groove under the control of self-locking runback detent mechanism (16).If thrust pin (5) drops in the vertical channel of L shaped groove, then the thrust that stressed probe (1) is produced is added on the thrust block (3), thrust block (3) again by thrust pin (5) with thrust on force block (6).Force block (6) then passes to thrust buffer gear (9).If thrust pin (5) is in the horizontal slot of L shaped groove, because of thrust pin (5) only slides in this horizontal slot, force block (6) can not get thrust.This is equivalent to a power-transfer clutch, and the former is the power-transfer clutch closure, and the latter is a disengaging of clutch.
Said buffer gear (9) is made up of screw rod (7), pressure spring (8), shift fork (10), little axle (11), screw rod (7) one ends are connected with force block (6), the other end is with spring (8), passes the hole of the little axle (11) on the shift fork (10), and the termination is fixed with nut.This mechanism be with the thrust on the force block (6) on pressure spring (8), by spring (8) buffering, power is passed to shift fork (10), shift fork (10) converts reciprocating power to angular motion power, by rotating shaft (12), power is passed on the brake shoe (14) then.
The brake shoe of said mine car dead-man's device (14) is a pair of cast iron product that is installed in respectively on the tramcar wheel side bearing frame (13), and bearing support (13) is contained in the two ends of rotating shaft (12).Under non-braking state, brake shoe (14) is subjected to the tension of spring (15), does not rub with wheel.
When needs brake, can operate the brake gear on the hauling engine, hauling engine speed is slowed down.This moment, haulage speed was less than being pulled speed, make near the stressed probe (1) of first mine car of hauling engine at first with the device of meeting and discussing (21) collision of hauling engine, at this moment stressed probe (1) has stopped the motion to hauling engine, and mine car still continues ahead running by force of inertia.Make stressed probe do motion backward like this, force of inertia is added on the thrust block (3) with respect to mine car.If engaging and disengaging gear this moment (4) is in closure state, the position that is thrust pin (5) is in the vertical channel of force block (6), force of inertia will be by force block (6), screw rod (7) spring (8), shift fork (10), rotating shaft (12), bearing support (13), brake shoe (14) is moved to axis wheel, rub with wheel, produce brake action, the speed of first mine car is slowed down.Speed because of first mine car slows down equally, and and then above-mentioned phenomenon takes place second mine car, and the result also produces braking.By that analogy, all are pulled mine car and all produce braking successively, and the speed of permutation mine car can slow down very soon so, realize quick short range braking.
When mine car will be when preacceleration moves, because of the speed of hauling engine at first greater than mine car speed, the distance of hauling engine and first mine car is drawn back, stressed probe (1) is held out by spring (2), the thrust that is added in pressure spring (8) is disengaged, brake shoe (14) is drawn back by spring (15), removes braking state.First mine car and hauling engine with speed after, the mine car of back also order is removed braking state, with the hauling engine ahead running, the situation when this is ahead running.
When the function of dead-man's device need be removed, its way was that the thrust pin (5) on the engaging and disengaging gear (4) is in the horizontal slot on the force block (6).
In the bottom of force block (6) a self-locking runback detent mechanism (16) is installed.On the slide block set (17) on the said self-locking runback detent mechanism (16) slide block (19) is housed, there is one to be carved with the groove that is similar to b shape on the slide block (19), a slidably locating dowel pin (18) is housed in the groove, and the other end of locating dowel pin (18) is installed on the slide block.
The device that is used for controlling this detent mechanism is a collision mechanism (20), and this mechanism is a buting iron that has two inclined-planes that is fixed on the roadbed.
The slide block (19) that makes each mine car dead-man's device bumps with buting iron through collision mechanism, makes slide block (19) to top offset.If locating dowel pin (18) is in a position, locating dowel pin this moment (18) moves to the b locking position with respect to slide block (19) along solid arrow; Slide block (19), force block (6) are held up, and thrust pin (5) falls into vertical channel, and device is in the preparation braking state.When slide block (19) collided with collision mechanism (20) once more, locating dowel pin returned a point along dotted arrow, and slide block (19) falls, and thrust pin (5) is got back to the horizontal slot left side, and engaging and disengaging gear is in released state, and brake function is disengaged.
The enforcement of automatic brake device for mine cars has only changed the brake gear by traction locomotive, the method for retarding braking, thus can give full play to the propulsive efficiency of traction locomotive, improve transport capacity, and to transporting positive meaning safely.
This dead-man's device is full mechanical, can implement on the basis that does not change existing mine car structure. This dead-man's device utilizes inertia force to do brake power, neither consumes any energy, and is again free from environmental pollution.
