Colliery is the proportional space that the mankind are excavated when digging is rich in the geological stratification for having coal, generally includes tunnel, well
Cave and face etc..Coal is topmost solid fuel, is one kind of kaustobilite.It was grown by certain geological epoch
Plant in great numbers, in suitable geological environment, thick-layer is gradually piled into, and be buried in water-bed or silt, by very long
The geochronic natural incoalation in matter age and formed.In the world in Various Geolcgical Ages, with the Carboniferous Period, the Permian Period, Jurassic Period and
Producing coal is important coal-forming age at most in three stratum recorded.The phosphorus content of coal is generally 46~97%, brown to black,
With dimness to metallic luster, coal is described as " the real grain " of industry.
Noise is a kind of main occupational hazards of coal mining industry, and not only the live worker's of influence is healthy, while
Influence safety in production.Especially in fully mechanized mining, driving face, because machinery equipment power is big, equipment is more, working space is narrow and small,
Reflecting surface is big, easily forms mixed noise, has a strong impact on the health and production safety of workman.In each noise like, car puller noise
The a great problem of live worker is always annoying, so far still without effective solution.
The content of the invention
For a variety of deficiencies of prior art, inventor in long-term practical activity, by pin-gear car puller
Noise source is analyzed, and combines requirement of the working environment to pin-gear car puller, has formulated optimization noise reduction measure.Using high score

Low axle friction, weakens noise；Noise reduction layer is set in running wheel outer surface, and wheel shaft is fixed by holding out against part, reduce noise
While extend service life, ensure worker's occupational health.
To achieve the above object, the present invention provides following technical scheme：
One kind passage car, including vehicle frame, platform, running wheel and go-cart pawl, the go-cart pawl is hinged with vehicle frame, and go-cart pawl and
The contact surface of platform is provided with noise reduction layer, and the running wheel is installed on vehicle frame by wheel shaft, and the two ends of the wheel shaft are arranged with axle
Hold, the running wheel outer surface is provided with noise reduction layer, and it is sheathed on bearing, the wheel shaft is located at the position set between vehicle frame and running wheel
Noise reduction protective case is provided with, the platform is provided with and holds out against part, and holds out against the lower end of part and wheel shaft offsets.
Further, the noise reduction layer is made up of macromolecule polyurethane resin.
Further, the noise reduction layer is set to more than two-layer.
Further, the noise reduction protective case is nylon jacket.
Further, the part that holds out against is for bolt, and holds out against part through platform setting.
Further, the part that holds out against is set to multiple, and multiple holds out against part and is distributed on platform along wheel shaft.
Further, the part that holds out against is set to two.
A kind of pin-gear car puller, comprising above-mentioned passage car.
The beneficial effects of the invention are as follows：
The contact surface of go-cart pawl and platform is made using macromolecule polyurethane resin, to reduce collision noise；On wheel shaft
Noise reduction protective case is arranged, axle friction is reduced, weakens noise；In addition, noise reduction layer is set in running wheel outer surface, and by holding out against part pair
Wheel shaft is fixed, and service life is extended while reducing noise, improves worker's operating environment, ensures that worker's occupation is strong
Health.

Specific embodiment
In order that those skilled in the art more fully understand technical scheme, it is right with reference to accompanying drawing of the invention
Technical scheme carries out clear, complete description, and based on the embodiment in the application, those of ordinary skill in the art exist
Other the similar embodiments obtained on the premise of not making creative work, should all belong to the scope of the application protection.
Embodiment one：
As shown in Figure 1-2, a kind of passage car, including platform 1, vehicle frame 2, running wheel 4 and go-cart pawl 3, the platform 1 are located at car
The top of frame 2, both are fixedly connected, and the platform 1 is used to carry mine car, and the go-cart pawl 3 is hinged with vehicle frame 2, and go-cart pawl 3 and
The contact surface 11 of platform 1 is provided with noise reduction layer, and than front end weight, front end tilts for the rear end of the go-cart pawl 3, and the noise reduction layer is by height
Molecule polyurethane resin is made, and to reduce collision noise, the noise reduction layer is set to two-layer, increases the service life, two-layer noise reduction layer
Between fixed using binder or bolt.In some other embodiment, the noise reduction layer can also be had high-strength using other
Degree, tear-proof, the macromolecular material of antiwear characteristic are made.
The running wheel 4 is installed on vehicle frame 2 by wheel shaft 6, and the wheel shaft 6 runs through vehicle frame 2, and its two ends is arranged with bearing,
The outer surface of the running wheel 4 is provided with noise reduction layer, and the noise reduction layer is made up of macromolecule polyurethane resin, reduces running wheel 4 and interorbital
Friction noise, noise reduction layer is set to four layers, increases the service life, solid using binder or bolt between four layers of noise reductions layer
It is fixed.In some other embodiment, the noise reduction layer can also have the height of high intensity, tear-proof, antiwear characteristic using other
