Abstract

The utility model provides a hook lock type tramcar plug pin. The hook lock type tramcar plug pin overcomes the defect that accidents often occur due to the fact that an existing tramcar connecting plug pin is not good in connection effect. The hook lock type tramcar plug pin comprises a plug pin shaft, a shoulder is fixedly arranged on the top portion of the plug pin shaft, and the diameter of the shoulder is larger than that of the plug pin shaft. A U-shaped clamping seat is fixedly arranged on the top portion of the shoulder, and an L-shaped latch hook is hinged inside the U-shaped clamping seat. The short wall of the L-shaped latch hook is arranged between two side walls of the U-shaped clamping seat, a hinging hole is formed in the end portion of the short wall, a rivet is arranged in the hinging hole in a penetrating mode, two ends of the rivet are respectively fixedly arranged on two side walls of the U-shaped clamping seat, and a hook is arranged on the end portion of the long wall of the L-shaped latch hook. The short wall, the long wall and the hook of the L-shaped latch hook are all on an identical plane. The hook lock type tramcar plug pin is simple in structure, reasonable in design, convenient to use, good in disconnecting resistant effect, safe and reliable and capable of effectively preventing the occurrence of transportation accidents, and finally achieves the purpose of safe production of mines.

Description

Hook lock formula mine car latch

Technical field

The utility model relates to the Transport Machinery technical field, and particularly a kind of device for the various mine cars connections of down-hole, mine transport systems specifically is a kind of hook lock formula mine car latch.

Background technology

The used various mine cars of overwhelming majority mines connect latches to be had so several: the anticreep latch of common ball end, band lateral pin, at the anticreep latch of latch afterbody punching, two kinds of anticreep latches of back all are in order to prevent that mine car latch in operational process from jumping out in anti-raising one's hat, to cause the various shipping accidents that occur behind the mine car sport car.Even if like this, jumping out the various shipping accidents that cause because of pin also happens occasionally, the major cause that these accidents take place is: mine car the is anti-bump between the mine car and mine car in use of raising one's hat, bump between large-scale material and mine car are prevented raising one's hat, under the accident condition to the anti-bump of raising one's hat of mine car, more than these situations caused anti-distortion of raising one's hat, the mine car latch of band anticreep lateral pin is worn to enter and is used common latch instead, be to use the mine car latch of afterbody punching to require to use the iron wire binding not according to rules, aggregate analysis: 1, existing mine car latch anticreep effect has certain defective, and effect is poorer behind the anti-collision deformation of raising one's hat.2, the mine car latch in band anticreep hole uses inconvenience, breaks rules and regulations easily to use in operating process.

Summary of the invention

The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of novel hook lock formula mine car latch is provided.

The utility model is achieved through the following technical solutions:

A kind of hook lock formula mine car latch comprises bolt axle, and the shoulder first is fixedly arranged at the top of bolt axle, and shoulder first diameter is greater than the bolt axle diameter; U-shaped deck is fixedly arranged at shoulder first top, is hinged with L type latch hook in the U-shaped deck; The shortwall of L type latch hook places between the two side of U-shaped deck and the shortwall end offers hinge hole, is equipped with rivet in the hinge hole, and the two ends of rivet are separately fixed on the two side of U-shaped deck, and the longwell end of L type latch hook is provided with crotch; The shortwall of L type latch hook, long-armed and crotch all are positioned at same plane.

During use, as shown in Figure 4, bolt axle of the present utility model is inserted in anti-the raising one's hat on the mine car vehicle frame, the shoulder first on the bolt axle is fastened on the anti-port of raising one's hat, and L type latch hook falls by deadweight, and the crotch of L type latch hook will prevent that the bottom of raising one's hat catches on.Bolt axle is in anti-raising one's hat, and it has only 2mm with the diameter clearance between anti-raising one's hat, and radially wobbles maximum clearance 4mm, can guarantee that latch hook can not take off bottom anti-the raising one's hat.Bolt axle can rotate by 180 degree in anti-raising one's hat, and has guaranteed that the utility model can not jump out anti-raising one's hat at an arbitrary position.Bolt axle axial runout (up and down) has only the 5mm gap, can guarantee that also bolt axle can not jump out of anti-raising one's hat.When needs were extracted the utility model from anti-raising one's hat, the L type that lifts latch hook that must be artificial was also upwards extracted.

Further, the long 90mm of shortwall of described L type latch hook, long-armed long 125mm, the long 44mm of crotch.

The utility model apparatus structure is simple, reasonable in design, easy to use, good anti-drop effect, safe and reliable, can effectively prevent the generation of shipping accident, finally realizes the purpose that mine safety is produced.
