Description
Technical field
The utility model relates to a kind of temporary support device, specifically a kind of damping type temporary support device for tunnelling machine.
Background technology
Tunnelling temporary lining problem is a technical barrier of puzzlement Safety of Coal Mine Production always.The temporary lining form that domestic colliery generally uses at present alters pipe forestope and pillar adds crossbeam two kinds of modes.Although design a kind of vehicle-mounted temporary support device for development machine for above situation, substitute original temporary lining form.But large because shaking when this vehicle-mounted temporary support device for development machine uses in rock gangway, cause frequent damage, causing piggyback temporary support device to obtain cannot normally use, and the safety of workman can not get ensureing.
For this reason, improvement is made to existing structure, design a kind of temporary support device with damping performance, solve the problems referred to above.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides a kind of damping type temporary support device for tunnelling machine.
The utility model solves the technical scheme that its technical problem adopts:
A kind of damping type temporary support device for tunnelling machine, comprise upper frame, outer column and folding ram, one end of described outer column and folding ram is rotationally connected with development machine body respectively, and the other end of folding ram is also rotationally connected with on outer column, described upper frame rear end is hingedly connected with inner column, connected by hoist cylinder between described inner column and above-mentioned outer column, the support cylinder be obliquely installed also is connected with between described upper frame rear portion and outer column, wherein, drawing cylinder is connected with between described upper frame front portion and outer column, and the control circuit of described drawing cylinder and above-mentioned folding ram, hoist cylinder, the control circuit of support cylinder is connected to the master control circuit of development machine body.
Further, the soffit of described upper frame is provided with beam.
Concrete, bottom and the outer column of described drawing cylinder are articulated and connected, and the pull bar top of drawing cylinder and upper frame removably connect.
More specifically, an end of described outer column and the bottom of folding ram are connected to development machine body respectively by rotating shaft, and the pull bar top of folding ram is also articulated and connected on outer column; The other end of described outer column is fixedly connected with bottom hoist cylinder, and the pull bar top of hoist cylinder is fixedly connected with inner column.
A kind of beneficial effect compared with prior art produced for the damping type temporary support device of tunnelling machine of the present utility model is:
1) the utility model is assemblied in the cantilever middle and upper part of development machine body, and structure is simple, little to the transformation amount of development machine body, realizes the do mechanization operation of temporary lining, reduces operation intensity, improve drivage efficiency, ensure that the safety of Anchor Care workman;
2) in the utility model, fixed by drawing cylinder between upper frame and outer column, operating cyloinder operating valve, drawing cylinder is regained, make upper frame contacting with the cover plate of development machine body tightly, and in upper frame bottom, beam is installed, between upper frame and cover plate, become flexible contact, make piggyback temporary support device and development machine become an entirety, reduce the destruction that vibrations produce.

Detailed description of the invention
Below in conjunction with accompanying drawing 1,2, a kind of damping type temporary support device for tunnelling machine of the present utility model is described in detail below.
As shown in accompanying drawing 1,2, a kind of damping type temporary support device for tunnelling machine of the present utility model, its structure comprises upper frame 2, outer column 3 and folding ram 4;
An end of described outer column 3 and the bottom of folding ram 4 are connected to development machine body 1 respectively by rotating shaft, and the pull bar top of folding ram 4 is also articulated and connected on outer column 3;
Described upper frame 2 right-hand member is hingedly connected with inner column 5, is connected between described inner column 5 and above-mentioned outer column 3 by hoist cylinder 6, is also connected with the support cylinder 7 be obliquely installed between described upper frame 2 right part and outer column 3;
Be connected with drawing cylinder 8 between described upper frame 2 left part and outer column 3, bottom and the outer column 3 of described drawing cylinder 8 are articulated and connected, and pull bar top and the upper frame 2 of drawing cylinder 8 removably connect;
And the control circuit of the control circuit of described drawing cylinder 8 and above-mentioned folding ram 4, hoist cylinder 6, support cylinder 7 is connected to the master control circuit of development machine body 1.
The soffit of described upper frame 2 is provided with beam 9.
When the utility model is in contraction state, pull bar top and upper frame 2 bolt of drawing cylinder 8 removably connect, and the pull bar of drawing cylinder 8 is in contraction state, and upper frame 2 carries out flexible contact with the cover plate of development machine body 1 by beam 9;
When support is stretched out by needs, first the link position of manual teardown drawing cylinder 8 and upper frame 2 is wanted, then operating grip is promoted, open folding ram 4, coordinate another operating grip simultaneously, support cylinder 7 is opened simultaneously, under the state keeping upper frame 2 to be horizontal, folding ram 4 promotes outer column 3 and rotates around the axis, folding ram 4 also rotates around the axis simultaneously, thus promotion hoist cylinder 6 and inner column 5 turn forward, and then open hoist cylinder 6, make hoist cylinder 6 slowly increase, reach tunnel desired height.
Draw to draw a conclusion after test of many times uses, the utility model is assemblied in the cantilever middle and upper part of development machine body 1, and structure is simple, little to the transformation amount of development machine body 1, realize the do mechanization operation of temporary lining, reduce operation intensity, improve drivage efficiency, ensure that the safety of Anchor Care workman.On the basis of original supporting, fixed by drawing cylinder 8 between upper frame 2 and outer column 3, operating cyloinder operating valve, drawing cylinder 8 is regained, make upper frame 2 contacting with the cover plate of development machine body 1 tightly, and in upper frame 2 bottom, beam 9 is installed, between upper frame 2 and cover plate, become flexible contact, make piggyback temporary support device and development machine become an entirety, reduce the destruction that vibrations produce.
