Abstract
The invention discloses an anti-disengaging device for mine cars, which comprises a cushion connection device, a pin bolt, a protection cover, a compression bar and a compression spring. The protection cover is fixed on the upper side of the cushion connection device. A cover board is fixed on the upper side of the protection cover. The pin bolt is installed in the centre portion of the cover board. A fixed groove is arranged on the lower side of the centre portion of the cover board. The lower end of the compression bar contacts with the upper end surface of the pin bolt by passing through the pin bolt and the compression spring. A gasket is mounted between the compression spring and the cover board. A pull ring is disposed at the upper end of the compression bar. The invention has the advantages of safe and reliable using, high mechanical strength, reasonable design, simple structure, easy operation, small volume, light weight, convenient assemble and disassemble, easy transport, low manufacturing cost and ease of use. The invention totally eliminates the hidden danger of channeling pin, decoupling and sliding down.
Description
Technical field
The present invention relates to a kind of anticreep latch, be specifically related to a kind of mine car anti-loosing device.
Background technology
At present, China's coal-mine is aboveground, the overwhelming majority uses mine car to transport in the transport of down-hole, and the attaching parts of mine car is generally common latch, and existing common latch anti-loose function is not strong.When in transportation, mine car is crossed grade change point or crossed electrodeless rope sheave, its common latch is very easily deviate from, and then causes the generation of derailing accident, brings great hidden danger to the safety in production in colliery.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of mine car anti-loosing device, it is safe and reliable, mechanical strength is high, thoroughly can eliminate the hidden danger of altering pin, unhook and sport car, reasonable in design, structure is simple, easy and simple to handle, compact, lightweight, easy accessibility, be convenient to carrying, productive costs is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of mine car anti-loosing device, comprising buffer connecting rods and pitch the pin that is contained on described buffer connecting rods, it is characterized in that: also comprising protective case, depression bar that side is fixedly installed card column and be arranged on described protective case internal cavities for compressing the Compress Spring of described depression bar; Protective case is fixedly installed on the upside of described buffer connecting rods; cover plate is fixedly installed on the upside of described protective case; pin-and-hole is provided with in the middle part of described cover plate; in the middle part of described cover plate, downside is provided with hold down groove; described depression bar lower end contacts with described pin upper surface with described Compress Spring through described pin-and-hole; be provided with pad between described Compress Spring and described cover plate, described depression bar upper end is provided with draw ring.
Above-mentioned mine car anti-loosing device, is characterized in that: described cover plate is fixedly connected with by screw with described protective case.
Above-mentioned mine car anti-loosing device, is characterized in that: described protective case is fixedly connected with by screw with described buffer connecting rods.
The present invention compared with prior art has the following advantages:
(1) this mine car anti-loosing device is safe and reliable, and mechanical strength is high, thoroughly can eliminate the hidden danger of altering pin, unhook and sport car.
(2) this mine car is very reasonable with anti-loosing device design, and structure is simple, and depression bar only need insert in the pin-and-hole of cover plate by operating personal, operates very easy.
(3) this mine car anti-loosing device compact, lightweight, easy accessibility, is convenient to carrying.
(4) this mine car is simple by anti-loosing device production technology, and requirement on machining accuracy is low, and a lot of parts are convenient to produce, buy all very much, and thus its productive costs is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
A kind of mine car anti-loosing device as Figure 1-Figure 4, comprise buffer connecting rods 6 and pitch the pin 5 be contained on described buffer connecting rods 6, also comprising protective case 3, depression bar 4 that side is fixedly installed card column 4-1 and be arranged on described protective case 3 internal cavities for compressing the Compress Spring 7 of described depression bar 4; Protective case 3 is fixedly installed on the upside of described buffer connecting rods 6; cover plate 2 is fixedly installed on the upside of described protective case 3; pin-and-hole 2-1 is provided with in the middle part of described cover plate 2; in the middle part of described cover plate 2, downside is provided with hold down groove 2-2; described depression bar 4 lower end contacts with described pin 5 upper surface with described Compress Spring 7 through described pin-and-hole 2-1; pad 8 is provided with between described Compress Spring 7 and described cover plate 2; described depression bar 4 upper end is provided with draw ring 1, and draw ring 1 can help user to insert easily or extract depression bar 4.
In the present embodiment, described cover plate 2 is fixedly connected with by screw with described protective case 3, and screw connects safe and reliable, cheap.
In the present embodiment, described protective case 3 is fixedly connected with by screw with described buffer connecting rods 6, and screw connects safe and reliable, cheap.
The working process of mine car anti-loosing device of the present invention is: first this mine car anti-loosing device is fixed on control position, depression bar 4 inserts in pin-and-hole 2-1 by hand-held draw ring 1, rotating draw ring 1 makes the card column 4-1 inlay card of depression bar 4 in hold down groove 2-2, depression bar 4 lower end compresses pin 5, Compress Spring 7 automatic impaction pad 8 simultaneously, namely pad 8 prevents depression bar 4 from getting loose because of vibration by card column 4-1, thus effectively prevents pin 5 from occurring altering the problems such as pin.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solution of the present invention.
