Abstract
The utility model is a kind of lorry connecting pin, comprises cylinder shank, and the top end face of cylinder shank is provided with suspension ring, the sidewall bottom cylinder shank offers blind hole groove, and the bottom face of cylinder shank offers the chute communicated with blind hole groove; Be fitted with spring pin in blind hole groove and be provided with Compress Spring between spring pin inner end and blind hole groove bottom land, spanner is fixed with spring pin through after chute.The utility model achieves the automatic car locking function of lorry, ensure that lorry safe in operation, prevents the accidents such as vehicle disconnection, sport car, avoids occurring great personal casualty and device damage; The utility model design science, make simple, easy to process, simple operation, can realize batch manufacturing completely, can promote the use of in each large colliery.
Description
Technical field
The utility model relates to a kind of parts of underground coal mine lorry, specifically a kind of lorry connecting pin.
Background technology
In coal production, mine inclined tube-train hoisting transport is the important component part of shaft production, and it, through each production link of mine, is related to the transport of colliery all devices and material.Its battle line is grown, is involved a wide range of knowledge, and the geographical environment of application is complicated and changeable, and special work post is many, and technology is strong.Therefore the safe operation of inclined tunnel transporting system is significant with guarantee miner life and health to mine safety production.Coal mine sloping lane transports modal accident by analysis just has because connecting pins is given up the throne in transportation, promotes mine car (lorry) and forms derailing accident when losing connection, and its consequence is very serious, causes casualties and non-fatal accident.
At present, head connection mode between lorry adopts cylindrical pin to wear chain link connection always, give up the throne for preventing this pin, process a hole at column part end, be convenient to wear galvanized wire and play self-locking action, but in actual applications, operating personal is very easily neglected, forget pin-and-hole wear that this important step of galvanized wire or galvanized wire wear tight, in vehicle operation, there will be unhook sport car and cause the accident.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, and provides a kind of lorry connecting pin of brand new.
The utility model is achieved by the following technical solution:
A kind of lorry connecting pin, comprise cylinder shank, the top end face of cylinder shank is provided with suspension ring, the sidewall bottom cylinder shank offers blind hole groove, and the axis of blind hole groove and the axes normal of cylinder shank are arranged; The bottom face of cylinder shank offers along the axis direction of blind hole groove the chute communicated with blind hole groove; Be fitted with spring pin in blind hole groove and between spring pin inner end and blind hole groove bottom land, Compress Spring be installed, spanner is fixed with spring pin through after chute, under the effect of Compress Spring elastic force, spanner by overhead at the trough of chute and the outer end of spring pin is exposed to the outside of blind hole groove.
The main operational principle of the utility model connecting pin is: when cylinder shank will insert coupling link, by promoting spanner, the spring pin be embedded on cylinder shank is pushed in blind hole groove, cylinder shank is through after coupling link, unclamp spanner, spring pin is just ejected blind hole groove after losing external force by Compress Spring, make spring pin automatic locking coupling link, achieve the function of automatic car locking.In the absence of external forces, spring pin is difficult to break off relations, and avoids situation spring pin occurring and gives up the throne, has stopped the generation of derailing accident.When lorry needs to be separated, as long as operating personal promotes spanner gently, spring pin is pushed in blind hole groove, release connection ring, cylinder shank can be taken out.
Further, the outer end of spring pin is wedge-shaped design, the benefit of such design is: when cylinder shank will insert coupling link, only firmly need descend slotting cylinder shank, under the tapered end of spring pin and coupling link interact, spring pin can be pushed in blind hole groove automatically, reaches time saving and energy saving, conveniently object.
The beneficial effects of the utility model are:
1) the utility model achieves the automatic car locking function of lorry, ensure that lorry safe in operation, prevents the accidents such as vehicle disconnection, sport car, avoids occurring great personal casualty and device damage;
2) the utility model design science, make simple, easy to process, simple operation, can realize batch manufacturing completely, can promote the use of in each large colliery;
3) the utility model productive costs is low, and consumptive material is few, can save substantial contribution, has greatly saved human and material resources, financial resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cylinder shank, 2-suspension ring, 3-blind hole groove, 4-chute, 5-spring pin, 6-Compress Spring, 7-spanner.
Detailed description of the invention
Do to state further to the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of lorry connecting pin, comprises cylinder shank 1, and the top end face of cylinder shank 1 is provided with suspension ring 2, the sidewall bottom cylinder shank 1 offers blind hole groove 3, and the axis of blind hole groove 3 and the axes normal of cylinder shank 1 are arranged; The bottom face of cylinder shank 1 offers along the axis direction of blind hole groove 3 chute 4 communicated with blind hole groove 3; Be fitted with spring pin 5 in blind hole groove 3 and between spring pin 5 inner end and blind hole groove 3 bottom land, Compress Spring 6 be installed, spanner 7 is through fixing with spring pin 5 after chute 4, under the effect of Compress Spring 6 elastic force, spanner 7 by overhead at the trough of chute 4 and the outer end of spring pin 5 is exposed to the outside of blind hole groove 3.
During concrete enforcement, the outer end of spring pin 5 is wedge-shaped design.
