Background technology:

In the mine of modern fully-mechanized mining, especially in the coal mining of well palace, the driving in tunnel is the bottleneck of restriction manufacturing schedule always.Because the tunnel is the necessary condition of all activities in production of down-hole, the headwork in tunnel not only affects the progress of other work, more is faced with many difficult problems: ventilation, supporting etc.Since modern fully-mechanized digging machine is used; though the operating type that is through with to a certain extent and " drilled and blasted " in the past; improved drivage efficiency; but still following: tunnel a step pitch and---shut down, withdraw from---and beat the work pattern of bolt support, its mechanizeding continuous operation ability can not get performance.

Summary of the invention:

The purpose of this utility model is the deficiency at above-mentioned prior art and technology, provide a kind of scientific structure reliable and meet the novel tunnelling advance support rack that condition is installed and used in the down-hole, can with the fully-mechanized digging machine coordinating operation, make development machine realize working continuously, the back that has just exposed in the driving is carried out temporary lining, allow the workman beat anchor pole, make permanent support at the development machine rear.Thereby realize the concurrent job of driving and permanent support, this all is significant to China and even worldwide tunnelling.

A kind of novel tunnelling advance support rack is connected to form by passing jack by two of A type and Type Bs; Every comprises column, it is characterized in that: it also comprises the A frame along beam, the suitable beam of B frame, A frame crossbeam, B frame crossbeam, and above-mentioned A frame crossbeam is provided with B frame crossbeam top and is connected otic placode, and its bottom, two ends is provided with needling; The A frame connects by bearing pin with the otic placode that is connected of A frame crossbeam along beam; The B frame connects by bearing pin with the otic placode that is connected of B frame crossbeam along beam; The needling of the column cap of column and A frame crossbeam and B frame crossbeam is connected; Be connected with the ship shape suspension column at the bottom of the post of each column.When assembling connected, the A frame all was positioned at the top of A frame crossbeam and B frame crossbeam along beam along beam and B frame; A frame crossbeam and B frame crossbeam are alternately arranged.

The inside, two ends of described A frame crossbeam and B frame crossbeam is equipped with the thruster jack, and the movable telescopic end of jack is connected with side guard board.

Described B frame is provided with the movable telescopic beam along the front end of beam, links to each other with the body pillar of B frame along beam by the extensible canopy jack in it.

The utlity model has following characteristics:

1, all connections are simple bearing pin connection, adapt to the down-hole and install and use condition;

2, support is made up of the back timber of in any case arranged alternate and the column that is positioned at two ends, and it is little to take up room, and supporting back area is big, does not influence the development machine working space;

3, the walking manner of support is plug-type before and after the simple jack;

4, each jack of support is controlled by hydraulically operated valve, and convenient operation and control can realize advancing synchronously with fully-mechanized digging machine, boosts productivity greatly;

5, can as the length of fully-mechanized digging machine, increase or reduce number of holders according to actual needs.

The specific embodiment:

Embodiment:

With reference to Fig. 1-7, by A type and two novel lame advanced supporting racks that connect to form by passing jack 7 of Type B; Every comprises column 3, also comprises the A frame along beam A1, B frame suitable beam B1, A frame crossbeam A2, B frame crossbeam B2, and above-mentioned A frame crossbeam A2 is provided with B frame crossbeam B2 top and is connected otic placode 2-1, and its bottom, two ends is provided with needling 2-2; The A frame connects by bearing pin 6 with the otic placode 2-1 that is connected of A frame crossbeam A2 along beam A1; The B frame connects by bearing pin 6 with the otic placode 2-1 that is connected of B frame crossbeam B2 along beam B1; The needling 2-2 of the column cap of column 3 and A frame crossbeam A2 and B frame crossbeam B2 is connected; Be connected with ship shape suspension column 8 at the bottom of the post of each column 3.When assembling connected, the A frame all was positioned at the top of A frame crossbeam A2 and B frame crossbeam B2 along beam B1 along beam A1 and B frame; A frame crossbeam A2 and B frame crossbeam B2 alternately arrange, and the B frame is before.

The inside, two ends of described A frame crossbeam A2 and B frame crossbeam B2 is equipped with thruster jack 4, and the movable telescopic end of jack is connected with side guard board 5.

Described B frame is provided with movable telescopic beam B1-1 along the front end of beam B1, links to each other with the body pillar B1-3 of B frame along beam B1 by extensible canopy jack B1-2 in it.

Operating principle of the present utility model:

During holding state, as shown in Figure 5, column stretches out, and the A frame all contacts and the supporting back along beam B1 with the B frame along beam A1, and column suspension column 8 supports roadway floor; In the time of need being movably walking (among Fig. 5 be to advance left example), the column 3 that is connected with B frame crossbeam B2 is regained, then gravitate B frame falls to the B frame and rides on the A frame crossbeam A2 along beam B1, as shown in Figure 8, at this moment, pass jack 7 actions (stretching out), the B frame that then will be in suspended state is passed a step pitch forward, as shown in Figure 9, the column 3 of B frame stretches out then, supports the B frame.Equally, A frame column 3 is regained, and the A frame falls to the A frame and rides on the B frame crossbeam B2 along beam A1, passes jack 7 actions (withdrawal) then, and the A frame is spurred a step pitch forward, and column 3 supports, and entire bracket comes back to initial holding state.
