Abstract
A quick plugging type self-locking pin for a mine car is composed of a pin component and a pin base component, wherein the pin component comprises a pin body, a pressing cover, a handle and a check ring, the pressing cover and the handle are welded together, the upper portion of the pin body is sleeved with the pressing cover which can slide along the pin body, an annular groove and an annular boss are arranged on the upper portion of the pin body, and the upper end of the pin body and the check ring are welded together; the pin base component comprises a pin base, a spring, a locking rod and a screw plug, the pin base is welded to a mine car traction position, a through hole is formed in the pin base, internal threads are arranged at the outer end of the through hole, the spring and the locking rod are arranged in the through hole, and the outer end of the through hole is fastened through the screw plug. The quick plugging type self-locking pin is easy to operate, unlocking and pin pulling are achieved by holding the handle and lifting upwards, pin inserting and self-locking are achieved by putting the handle down, accidental pin disengagement is prevented, and the quick plugging type self-locking pin is especially suitable for bunching connection during mine car transportation.
Description
Technical field
The invention belongs to connection of mining vehicles connecting device, particularly one plugs mine car self-lock pin soon.
Background technology
In current mining conveying process, the bunching of mine car connects general plug formula mine car latch, and mine car is in Long-Time Service, because jolting, colliding, vibrate and cause key seat self-locking grooves to damage, lose lock pin function, mine car latch is surprisingly out of stock causes derailing accident, and potential safety hazard is large.
Summary of the invention
The invention provides a kind of easy and simple to handle, robust fast plug mine car self-lock pin.
The present invention adopts following technical scheme: a kind of fast plug mine car self-lock pin, comprise pin assemblies and key seat assembly, pin assemblies comprises shank, friction top, handle and baffle ring, together with friction top welds with handle, shank top is provided with circular groove and ring-shaped lug, together with shank upper end is welded with baffle ring, key seat assembly comprises key seat, spring, locking lever and screw plug, key seat is welded on car haul place, key seat is symmetrical arranged through hole, through hole outer end arranges negative thread, is provided with spring and locking lever in through hole, and through hole outer end is fastening by screw plug.
Feature of the present invention is: after shank inserts key seat, friction top continues to move down, and is inwardly passed by locking lever, and the inner termination of locking lever is inserted in the circular groove of shank, shank can not be moved, realize auto-lock function; When pulling pin, above handle, friction top moves, and locking lever moves the promotion of spring is lower outside, and locking lever inner termination shifts out from the circular groove of shank, realizes unlocking, handle in continuation, friction top effect baffle ring, and drive shank to move up, shank departs from key seat.
Shank of the present invention, key seat and locking lever, material is superior alloy steel, sturdy and durable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is pin assemblies structural representation of the present invention.
Fig. 3 is key seat unit construction schematic diagram of the present invention.
Detailed description of the invention
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of fast plug mine car self-lock pin of the present invention, comprise pin assemblies and key seat assembly, pin assemblies comprises shank 1, friction top 7, handle 11 and baffle ring 10, together with friction top 7 welds with handle 11, shank 1 top is provided with circular groove 8 and ring-shaped lug 9, together with shank 1 upper end is welded with baffle ring 10, key seat assembly comprises key seat 2, spring 3, locking lever 5 and screw plug 6, key seat 2 is welded on car haul place, key seat 2 is symmetrical arranged through hole 4, through hole 4 outer end arranges negative thread, spring 3 and locking lever 5 is provided with in through hole 4, through hole 4 outer end is fastening by screw plug 6.
During latch, the lower end of shank 1 is inserted in the centre hole of key seat 2 by portable handle 11, continue to transfer handle 11, shank 1 arrives the position shown in Fig. 1, handle 11 and friction top 7 continue to move down, and are inwardly passed by locking lever 5, and the inner termination of locking lever 5 is inserted in the circular groove 8 of shank 1, shank 1 can not be moved, realize bolt self-locking.
When pulling pin, on handle 11, friction top 7 moves, and locking lever 5 moves the promotion of spring 3 is lower outside, and locking lever 5 inner termination shifts out from the circular groove 8 of shank 1, realize unlocking, handle 11 in continuation, friction top 7 acts on baffle ring 10, drives shank 1 to move up, shank 1 departs from key seat 2, completes unblock and pulls pin.
The present embodiment not does any pro forma restriction to shape of the present invention, structure etc., every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and replacement, all belong to the protection domain of technical solution of the present invention.
