Abstract

A driving mechanism installed outside tunneller mainly aims to solve technical problems such as inconvenient installation and maintenance and adopts the following technical proposal: the outside of the center line of a tunneller and one side of a decelerator are provided with a prime mover driving and connected with a drive piece; the drive piece drives and is connected with the decelerator and adopts gear drive or chain wheel drive. The utility model is suitable for various tunnellers.

Description

The transmission mechanism that the development machine outside is arranged

Technical field:

The utility model relates to a kind of along the self-propelled machinery of work plane, particularly a kind of transmission mechanism.

Background technology:

Existing boom-type roadheader is a kind of collection cut, shipment, functions such as walking are in the coal cutting roadway heading equipment of one, the power transmission arrangment of its walking mechanism as shown in Figure 3, two transmission mechanisms are separately positioned on the both sides of development machine center line 00, engine 1 (hydraulic motor or motor) is positioned at the inboard of nearly center line 00, engine 1 concentric is connected in transmission mechanism 3 (as the walking reducer), the outside of transmission mechanism 3 connects walking mechanism 4, because the boom-type roadheader volume is little, compact conformation, engine 1 and transmission mechanism 3 are laid in the below of unit, and the inboard of the close nearly center line 00 of development machine, near apart from ground, installing space is minimum, the unit assembling is very inconvenient, and underground working is abominable, and the unit base plate often has ponding and coal slime, in case engine 1 produces fault, when needing maintenance, operating personnel must enter crawl space and overhaul, and sometimes even need dig pit on the ground to increase essential operating space, bring difficulty and danger to maintenance, and time-consuming, increase operation costs.

The utility model content:

Technical problem to be solved in the utility model is, a kind of development machine transmission mechanism that the outside is arranged is provided, and it is convenient that it can make unit that maintenance is installed, and improves the operation economic benefit.

The technical scheme in the invention for solving the above technical problem is: be provided with prime mover in the outside of development machine center line and a side of reducer, prime mover driven connects driving member, and driving member drives connection reducer.Prime mover drives through driving member and connects walking mechanism, and prime mover and walking mechanism are placed side by side the outside that is installed in the development machine center.

The setting of its driving member of the utility model mat, make prime mover be positioned at the outside of development machine, overcome the defective of traditional drive mechanism, the installation of transmission mechanism and maintenance no longer are subjected to the restriction of the narrow condition in space, can reduce the installation exercise time, and can shorten auxiliary maintenance time greatly, and improve the Homes Using TV and the production efficiency of development machine, improve the operation economic benefit.

Description of drawings:

Fig. 1 is that the gear train shaft that the utility model development machine outside is arranged is surveyed schematic diagram.

Fig. 2 is the motion sketch of Fig. 1.

Fig. 3 is the traditional structure schematic diagram.

The specific embodiment:

With reference to Fig. 1,2, the transmission of development machine walking mechanism includes prime mover 1, driving member 2, reducer 3 (as planetary reduction gear) and walking mechanism 4.

Prime mover 1 includes hydraulic motor (or motor) 11, brake 12 and power transmission shaft 13, two outsides that prime mover 1 is positioned at development machine center line 00 are the symmetry laying, the axis of the power transmission shaft 13 of prime mover 1 is connected walking mechanism 4 with reducer 3 axis 41 is parastate, and promptly driving wheel 41 axis of prime mover 1 axis and walking mechanism 4 are parallel.

Driving member 2, include casing 20, gear 21,22,23,24, axle 25,26 and bearing etc., gear 21,22,23,24, axle 25,26 and bearing are installed in the casing 20, gear 21 is installed on prime mover 1 power transmission shaft 13, is to drive with key, spline or other similar driving connected modes to connect; Or gear 21 establishes axle in addition, and this beam warp shaft coupling is to drive with power transmission shaft 13 and is connected, and gear 22,23 is a sloth wheel gear, is slidingly located in spools 25,26; Gear 24 is installed in to be on the input shaft extension of reducer 3 to drive and connects, and also can establish in addition to be to drive on the input shaft extension of beam warp shaft coupling and reducer 3 to be connected; Gear 21 and gear 22 engagements, gear 22 and gear 23 engagements, the transmission meshing relation of gear 23 and gear 24 engagements formation driving member 2; Another structural concept of driving member 2 by sprocket wheel 21 ', 24 ' and silent chain form, driving member 2 also can be installed in the casing 20, sprocket wheel 21 ' is installed on prime mover power transmission shaft 13, be the company of driving with key, spline or other similar driving connected modes, or sprocket wheel 21 ' is established axle in addition, this beam warp shaft coupling is to drive with power transmission shaft 13 and is connected, sprocket wheel 24 ' is installed in to be on the input shaft extension of reducer 3 to drive and connects, also can establish in addition to be on the input shaft extension of beam warp shaft coupling and reducer 3 to drive and be connected, be connected transmission by silent chain between sprocket wheel 21 ' and sprocket wheel 24 '; The another structural concept of driving member 2 by two sprocket wheels 21 ', 24 ' and high-test chain form, its structure is similar with above-mentioned silent chain transmission.

The utility model mat said structure scheme, engine 11, brake 12, power transmission shaft 13 by prime mover 1 are given driving member 2 with transmission of power, gear 21, sloth wheel gear 22,23 and gear 24 through driving member 2 are delivered to reducer 3, reducer 3 drives the creeper tread motion for the driving wheel 42 that is contained on the frame transmission of power through axle 41, realize the walking kinetic energy of walking mechanism, because its left and right prime mover 1 is laid in development machine bottom centre line 00 outside, it is convenient that maintenance is installed, shorten the auxiliary repair time greatly, improve the Homes Using TV and the production efficiency of development machine.
