Description
Technical field
This utility model is taken a step automatic moving type novel advance timbering group, is widely used in coal mine roadway gib field.
Background technology
During China's coal-mine tunnelling at present, support pattern visits empty top zone before all using a plurality of forestope (steel pipe or Fang Gang) to hang at top board along roadway direction, prevents top board roof fall from causing personal injury accidents.This front canopy support defect is: not having setting load, security reliability is poor, it is impossible to is supported trying hard to keep to empty top zone top board and protects, and operating process is complicated, and labor strength is big.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model proposes one and take a step automatic moving type novel advance timbering group.
One is taken a step automatic moving type novel advance timbering group, it is composed in series by front and back two frame, including back timber, telescopic jack, side arm top board, side arm column, after-frame column, side arm base, after-frame base, double leval jib under back timber, side arm on after-frame top board, after-frame back timber, advancing jack, side arm.Described column one end is connected with back timber, and one end is connected with base；Under described side arm, back timber is connected by advancing jack with after-frame back timber；Described top board is connected with back timber；On described side arm, back timber is installed and under side arm on back timber；Described telescopic jack one end is connected with back timber on side arm, and one end is connected with back timber under side arm；Described double leval jib lower end is connected with base, and upper end is connected with back timber.
Automatic moving type of taking a step of the present utility model novel advance timbering group has the advantage that
(1) each jack of support is controlled flexible by hydraulically operated valve control, operation, cancels a dead lift, alleviate the labor intensity of workman, can realize simultaneously advancing with work surface, be greatly improved productivity ratio, the motion of support can be automatically obtained, it is not necessary to increase workman's amount of labour.
(2) automatic moving type novel advance timbering group of taking a step is composed in series by front and back two frame, and two framves support each other, take a step alternately to walk, and immediately following the paces of development machine, the top board and two that immediate support is exposed is helped, it is achieved mechanization advance support.
(3) this utility model is cheap, simple in construction, durable practicality, simple to operate.
Accompanying drawing explanation
Fig. 1 is automatic moving type of taking a step novel advance timbering group structural representation.
In figure: 1-after-frame column, 2-after-frame back timber, 3-after-frame top board, 4-advancing jack, back timber under 5-side arm, 6-telescopic jack, 7-side arm top board, back timber on 8-side arm, 9-side arm column, 10-side arm base, 11-double leval jib, 12-after-frame base.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further, it should be appreciated that following example are merely to illustrate utility model not for the scope limiting utility model.
This utility model automatic moving type novel advance timbering group of taking a step straddles on development machine, and when development machine tunnels forward, support need to be followed development machine and be moved forward, and top board is carried out immediate support.During use, automatic moving type of taking a step novel advance timbering group moves frame process has Four processes, as shown in Figure 1, process one, side arm column 9 shrinks, and advancing jack 4 elongation passage side arm base 10 travels forward, and side arm column 9 hydraulic cylinder elongation side arm top board 7 is lifted and contacts with back；Process two, after-frame column 1 shrinks, and advancing jack 4 shrinks and pulls after-frame base 12 to travel forward, and after-frame column 1 hydraulic cylinder extends, and after-frame back timber 2 is lifted and contacts with back；Process three, telescopic jack 6 extends, and on side arm, back timber 8 travels forward together with side arm top board 7, and workman completes monomer jumbolter under the gib of top board and bores square, installs the support work such as anchor pole, networking；Process four, in order to not affect the cut work of next circulation development machine, telescopic jack 6 is shunk and is driven back timber 8 on side arm to retract backward a cycling distance.So repetitive process one to four, can realize the supporting purpose of novel advance timbering group.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; this this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope that this utility model is claimed.This utility model claims scope and is defined by appending claims and equivalent thereof.
