The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the present invention can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Below in conjunction with Fig. 2 to Fig. 3, the preferred embodiment of development machine of the present invention is described in further detail.
This preferred embodiment development machine comprises that development machine basic structure comprises cutting units 1, shovel board portion 2, first transporter 3, body 4, main walking mechanism 5, support portion 6, back, backplate portion 7, hydraulic system 8 and electrical system 9 and auxiliary propelling machine 10.That is to say that remove outside the auxiliary propelling machine 10, other each several part structure designs according to development machine arrangement in the correlation technique.Wherein, main walking mechanism can be walked at gallery or light grade tunnel by the individual responsibility development machine.
Main walking mechanism 5 is driven by first drive unit.Auxiliary propelling machine is driven by second drive unit.And, second drive unit and first drive unit as can be seen from Figure 2, auxiliary propelling machine 10 is positioned at the rear end of main walking mechanism 5, and is connected with the back support portion 6 of development machine.
The present embodiment digging implement has following advantage:
When the first, the gradient is the tunnel descending driving of α, owing to be provided with auxiliary propelling machine in the rear end of main walking mechanism, and this auxiliary propelling machine can be driven by second drive unit, and this second drive unit is independent of first drive unit as main walking mechanism power source; Therefore, auxiliary propelling machine can support complete machine work, can assist main walking mechanism to drive the complete machine walking again, thereby, the tractive force of development machine complete machine improved, namely improve development machine in the driving moment of heavy grade tunnel walking, reduced grounding pressure, increased adhesive power, avoided skidding, make development machine can realize quick transfer, further improve the compliance of roadway construction;
The second, because auxiliary propelling machine is arranged at the rear end of main walking mechanism, therefore, move behind the position of centre of gravity of development machine, improve job stability;
Three, auxiliary propelling machine is directly connected in the rear end of main walking mechanism, can not occur in the prior art, and development machine connects the existing potential safety hazard of winch by wire rope, and easy to operate.
In the present embodiment, development machine comprises two auxiliary propelling machines 10; Each auxiliary propelling machine 10 is arranged at the left and right sides of support portion 6, back, with respect to the development machine bilateral symmetry.In addition, left and right sides auxiliary propelling machine can independently moving, also can link.
Further, auxiliary propelling machine 10 can adopt crawler type walking mechanism, comprises the auxiliary running part 11 of crawler type and auxiliary mobile roof support 12; First end of auxiliary mobile roof support 12 is connected with the auxiliary running part 10 of crawler type; Second end of auxiliary mobile roof support 12 is fixedlyed connected with the back support portion 6 of development machine.Wherein, the auxiliary running part of crawler type comprises crawler belt and walking beam, and for a person skilled in the art, the structure of crawler-type traveling portion is known, present embodiment this is not done more speak more bright.
Further preferably, auxiliary propelling machine 10 can also comprise the elevating movement device, and the elevating movement device is connected between the back support portion 6 of auxiliary mobile roof support 12 and development machine.The benefit that the elevating movement device is set has two:
The first, when development machine keeps in repair, can be by the elevating movement device flexible, auxiliary support apparatus is supported complete machine, like this, main walking mechanism just can be unsettled, and then can make things convenient for inspection and the maintenance of main walking mechanism fault; Perhaps, by stretching of elevating movement device, rely on main walking mechanism to support complete machine, at this moment, auxiliary support apparatus is unsettled, and then can make things convenient for inspection and the maintenance of auxiliary propelling machine fault.
The second, when not needing support or auxiliary walking, by stretching of elevating movement device, auxiliary propelling machine is packed up, and then, the further realization of development machine complete machine is transferred fast.
For example, when development machine turns round, just auxiliary propelling machine can be packed up, like this, when turning, just need not coordinate the drive unit between main walking mechanism 5 and the auxiliary propelling machine 10.
In addition, about elevating movement device lifting separately in two auxiliary propelling machines, also lifting simultaneously.
Further, in the present embodiment, this elevating movement device comprises slideway 15, slide block 14 and telescopic oil cylinder 13; Telescopic oil cylinder 13 comprises first end and second end, and the back support portion 6 of first end and development machine is hinged; Second end and auxiliary mobile roof support 12 are hinged or fixedly connected; Slideway 14 is arranged at the back support portion 6 of development machine; Slide block 14 is slidingly connected with the inwall of slideway 15, and slide block 14 also is rigidly connected with auxiliary mobile roof support 12.When telescopic oil cylinder 13 motions, can drive the auxiliary running part 11 of crawler type and together move along the direction of slideway 14.
Certainly, need to prove that telescopic oil cylinder 13 also can adopt other mechanisms with Telescopic to substitute, for example, realize that other lifting gears of spiral lifting motion also can.This is known for those skilled in the art, and the present invention no longer too much illustrates at this.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
