Description

Universal rotary safe and automatic connector for mine car

The utility model relates to a kind of general mine car rotary type safety automatic hitching device.

On all kinds of mines of China, adopt 8 font mine car hook and cylinder plugs that mine car is connected (referring to Fig. 5) at present usually.When connecting mine car, electric locomotive driver and cooperate with car person and to drive up to the mine car place, by following car person's one portable hook, one portable cylinder plugs, earlier with the connecting frame body opening on the end propelling mine car of hook, in the vertical back patchhole that aligns with connecting frame and hook endoporus of cylinder plugs, when connecting with the second joint mine car, follow car person on the other hand hook to be set right and lift and make it to keep the footpath, balance in pitch, the commander that blows a whistle then starts electric locomotive, rapidly hand is decontroled in the moment that electric locomotive comes with car person, the moment that hook enters the connecting frame body opening is worn a lateral pin with cylinder plugs insertion and half-twist or on the top of cylinder plugs rapidly, prevents because of locomotive haulage shake or upset unhook accident.Particularly under mine, the light dark, the tunnel is narrow, and is uneven, under the sliding harsh environment of water multichannel, trainman and big with car person's physical demands is tired easily.If the trainman operates not yet done refining or misoperation, easily cause strong collision, all threatening workpeople's safety all the time.

The purpose of this utility model be for provide a kind of simple in structure, install easily, convenient disassembly, safe and reliable, be applicable to the general mine car rotary type safety automatic hitching device of all kinds of mines particular surroundings.

The utility model is achieved like this: the utility model comprises coupler body; the hook tongue; hand lever; connecting rod; pintle hook lock is (referring to Fig. 1; Fig. 2); knuckle pivot pin passes coupler body and the hook tongue connects hook tongue and coupler body; the hook tongue can rotate around knuckle pivot pin; portable lever and coupler body connect; one end of connecting rod is contained on the portable lever; the other end of connecting rod connects with pintle hook lock; pintle hook lock is contained on the locus of coupler body and can slides along the slideway on the coupler body; during work; if the hook tongue is not opened; just must rotate portable lever; the connecting rod that is contained on the portable lever moves backward; drive pintle hook lock and move backward, make pintle hook lock open (promptly separating), the hook tongue is rotated along knuckle pivot pin with the hook tongue along the coupler body slideway; make it to be open at normal or maximum position; when the latch on hook tongue and the mine car clashed into, the hook tongue rotated around knuckle pivot pin rapidly latch is hooked, and hook tongue tail is pinned by pintle hook lock.

Have in the utility model and pass pintle hook lock and be contained in torque spring on the portable lever, during work, when the hook tongue hooks latch, hook tongue tail and pintle hook lock rigidly connect the moment of touching, pintle hook lock is subjected to the effect of hook tongue tail thrust that the trend of motion is backward arranged, but because the effect of torque spring has prevented the trend that pintle hook lock moves backward, played automatic connection, shut, the effect of locking.

On the portable lever in the utility model eccentric boss is arranged, the control mechanism thread connection is on eccentric boss, and control mechanism comprises locating dowel pin and the pressure spring that is contained on the locating dowel pin.

Two general mine car rotary type safety automatic hitching devices can be connected (referring to Fig. 1) with thru-bolt, can rotate arbitrarily.

The utlity model has simple in structure, dismounting, maintenance, easy to use, advantage such as safe and reliable, cost is low, saves time, laborsaving, goes slick, and is rotatable, can connect automatically, and range of use is wide are installed easily.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Sequence number explanation among Fig. 5:

I hook II cylinder plugs

The utility model is by coupler body 1, hook tongue 3, connecting rod 4, portable lever 5, pintle hook lock 6 is formed, knuckle pivot pin 2 connects hook tongue 3 and coupler body 1, hook tongue 3 can rotate around knuckle pivot pin 2, one end and the portable lever 5 of connecting rod 4 link, on the connecting rod cover 12 lever regulated fixing screw 13 is housed, on the other end of connecting rod 4 guide groove is arranged, connecting rod pin 14 passes guide groove pintle hook lock 6 is linked to each other with connecting rod 4, connecting rod pin 14 can slide along guide groove in the guide groove of connecting rod 4, the front end of coupler body 1 is made splayed, when bumping against with hook tongue 3 tails middle part, main latch 15 play the guiding role, planar slot 18 and slideway 19 are arranged on the coupler body 1, afterbody to hook tongue 3 when planar slot 18 is used for 3 rotations of hook tongue plays the transition directional tagging, pintle hook lock 6 is contained on the locus of coupler body 1 and can does longitudinal sliding motion along the slideway on the coupler body 1 19, slideway 19 also works to prevent pintle hook lock 6 side travels simultaneously, and torque spring 7 passes pintle hook lock 6 and is contained on the portable lever 5, and dust cover 17 is housed above coupler body 1.During work, if hook tongue 3 is not opened, rotate portable lever 5, be contained in the just motion backward of connecting rod 4 on the portable lever 5, driving pintle hook lock 6 moves backward along the slideway on the coupler body 1 19, pintle hook lock 6 is opened, hook tongue 3 just rotates around knuckle pivot pin 2, make it to be open at maximum position, when main latch 15 collisions in hook tongue 3 and the connecting frame that is fixed on the mine car, hook tongue 3 rotates around main latch 15, end in contact and extrude the end face of pintle hook lock 6 before the afterbody of hook tongue 3 and the pintle hook lock 6, force pintle hook lock 6 to move backward, thereby but move forward the anti-left surface that keeps off at hook tongue 3 afterbodys along slideway 19 because the antagonistic force of torque spring 7 promotes pintle hook lock 6, pintle hook lock 6 has pinned hook tongue 3, played automatic connection, close, the effect of pinning, otherwise, if open hook tongue 3, rotate portable lever 5, along with the pintle hook lock of motion backward 6 of connecting rod 4 moves backward, hook tongue 3 is subjected to the traction of cylindrical work latch 15 can separate swivel hook tongue 3 with pintle hook lock 6.

With thru-bolt 16 two general mine car rotary type safety couplings are connected, and make it to go slick, and unload (referring to the Fig. 1) that can overturn 360 °.

Eccentric boss 8 is arranged on the portable lever 5 in the utility model, thread connection has control mechanism 9 on the eccentric boss 8, control mechanism 9 comprises locating dowel pin 10 and the compression spring 11 that is contained on the locating dowel pin 10, on the coupler body 1 with on the locating dowel pin 10 cooresponding positions shrinkage pool first 20 is being arranged, shrinkage pool second 21, when rotating portable lever 5, when locating dowel pin 10 falls into shrinkage pool first 20, control mechanism 9 can play the auxiliary positioning locking, when the portable lever 5 of rotation, when making locating dowel pin 10 fall into shrinkage pool second 21 (this moment, pintle hook lock 6 moved backward), can overcome the application force of torsion spring 7, portable lever 5 can not turn round, and pintle hook lock 6 standard-sized sheets are fixed, and can reach the purpose of safe in operation.

The utility model can be used for mine car or the winch inclined shaft connects (referring to Fig. 4), also can be used for other all kinds of general-purpose vehicles, such as the frequent occasion of dismounting of the connection of automobile, tractor or elevator, connect such as station, vehicle scheduling, harbour, traction when boats and ships pull in to shore.

According to the practical structures geometry of various types of vehicles coupling arrangement, pintle hook lock is vertically fallen by the effect of self gravitation or spring force, reach shut, the purpose of locking.
