Description

Nothing wheel transport mine car under a kind of coal mine

Technical field

The utility model relates to transport mine car equipment technical field under coal mine, is specifically related under a kind of coal mine without wheel transport mine car.

Background technology

Efficiently, safety, intensive production is the direction of Dissertation of Development of Coal Industry, is also the important technical that improves coal enterprise's survival and development and the market competitiveness.But, along with Mechanion on even keel improves, due to the particularity of coal mine down-hole tunnel and environment, most of tunnels are fluctuating shape and arrange, make assistant conveyance become the bottleneck that restriction production efficiency improves, especially in the long assistant conveyance apart from tunnel, when the application of winch and rail transport is subject to limiting to, can only adopt original manpower as people's back of the body, the physical transportation mode of weight shouldering or lift, labour intensity is large, inefficiency, elapsed time is long, and safe controllability is not high.Therefore, in some Special Laneways, find a kind of rational assistant conveyance mode imperative, to reduce manual labor, change traditional old assistant conveyance modes such as manpower haul, improve to greatest extent mine production efficiency and economic benefit.

Coal mining car is mainly used in large tunnel under coal mine, medium and small inclined shaft cylinder, little inclined shaft crossheading and grass transportation, is a kind of main transportation device of coal mine ground and underworkings carry coal and spoil.Under coal mine, conventional mine car has side bottom dumping car, fixed mine wagon, bucket-tipping car, shuttle car, one-sided bend granby car etc.Side bottom dumping car can be realized continuous loading, unloading ore deposit, does not block bucket, and it is clean to unload ore deposit, can shorten the loading, unloading ore deposit time, has greatly improved work efficiency, but its service life is short, maintenance load large, transport systems poor reliability; That fixed mine wagon has is simple in structure, sturdy and durable, drag coefficient is little, load-carrying capacity is large, the feature such as easy to maintenance, but its have easy sport car, quality is large, manufacturing cost is high; Shuttle car mine car has the advantages such as handling speed is fast, damping performance good, be difficult for sliding down, but its freight volume is little, easily makes when driving cable mop floor, and travel way is more limited.Most colliery is all to adopt fixed mine wagon to realize the transportation of coal and spoil, but also there is the phenomenon of easy sport car in this mine car, for this phenomenon, safety regulations in coal mine regulation has each slope in the inclined tunnel transporting system of taking turns mine car that three above catchers must be set, " slope three gears " namely often said, yet this apparatus cost is higher, maintenance load lost efficacy more greatly and easily, so " slope three gears " catcher is also impracticable in practice, the problem of mine car sport car is not solved.Therefore, correctly determine transport systems, select transportation device, reasonably organize mine transport, design can realize in the underworkings of many gradients, landform more complicated safe, efficiently and cheaply assistant conveyance mode is imperative.

Utility model content

The purpose of this utility model is under existing coal mine, to have in wheel mine car because equipment designs the problem of unreasonable existence, provides under a kind of simple in structure, papery cost is low, " sport car " accident that can effectively prevent occurs coal mine without wheel transport mine car.

The purpose of this utility model can be achieved through the following technical solutions:

Nothing wheel transport mine car under a kind of coal mine, it is characterized in that: at the bottom of comprising vehicle frame, car, at the bottom of described car, comprise the first bottom girder and the second bottom girder, described the first bottom girder and the second bottom girder are symmetrically welded under described vehicle frame, the inner side of two rails, on described the first bottom girder and the second bottom girder side, be respectively equipped with outstanding guide beam, described guide beam is the I-groove of corresponding two rails respectively, and described guide beam is embedded in rail I shape channel-section steel, play the guiding role.

Preferably, described the first bottom girder, the second bottom girder divide other bottom surface, rear and front end to become cambered surface.Like this, be convenient to not have the mine car of wheel to rely on the Sledge type slip on the ground of the first bottom girder, the second bottom girder.

Described vehicle frame two ends are respectively arranged with energy disperser, on described energy disperser is installed at the bottom of car.Avoid mine car collision between any two to cause mine car corrupted.

Preferred, the projected length of described energy disperser is greater than projection at the bottom of described car, is so more conducive to protect mine car.

Described vehicle frame two ends are respectively arranged with adaptor union, and described adaptor union is arranged on described vehicle frame, and described adaptor union is provided with connecting bore, for the connection between a plurality of mine cars.

The beneficial effects of the utility model:

1) what, this practicality adopted is to have the wheel of wheel mine car to remove, will at the bottom of the car of mine car, be designed to the slide block combination of sled shape, saved like this coordinating of original axletree and antifriction-bearing box, avoid assembly error to cause the possibility of accident, make processing and manufacturing simpler, thereby also reduce costs.

2) what, the utility model adopted is without wheel construction, original friction of rolling is become to cliding friction, make at the bottom of car on directly domatic in tunnel to slide, increased friction coefficient, while moving on domatic, the gravity that the friction force that mine car is subject to is greater than mine car and the thing of freighting is all the time along the downward power of line of slope, so, when winch rope breaks suddenly, can make mine car be parked in domatic on, avoided the generation of " sport car ", made mine car transportation more safe and reliable.
