Abstract
The invention discloses a temporary supporting device of a driving machine. The temporary supporting device of the driving machine is composed of a large arm, a lifting jack, a cross beam, a longitudinal beam and a longitudinal beam jack, the lower end of the large arm is connected with a driving machine body, the upper end of the large arm is connected with the cross arm, one end of the lifting jack is connected with the large arm, the other end of the lifting jack is connected with the driving machine body, at least one longitudinal beam is arranged on the cross beam, a plurality of idler wheels are arranged on the longitudinal beam, and the longitudinal beam jack is connected between the cross beam and the longitudinal beam. The temporary supporting device can conduct continuous temporary supporting on a top plate in the coal cutting process of the driving machine, the driving machine can move without lifting the temporary supporting device, permanent supporting work is carried out behind the driving machine, driving and anchoring parallel work is achieved, and the driving efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of tunnelling machinery suspension device.
Technical background
The temporary support device majority of road heading machinery is arranged on cutting units at present, when coal cutting and movement, falls withdrawal, while beating anchor pole, again props again.The subject matter of its existence shows as: 1, can not move lasting supporting roof with road heading machinery; 2, cannot realize the parallel operations of road heading machinery coal cutting and permanent support; 3, the frequent lifting of temporary support device in tunneling process, obvious to roof destruction effect.
Summary of the invention
The object of the invention is to solve the problem that current road heading machinery temporary support device exists, a kind of temporary support device that can continue supporting is provided.
Road heading machinery temporary support device of the present invention is made up of large arm, lifting jack, crossbeam, longeron, longeron jack, large arm lower end is connected on development machine body, upper end is connected with crossbeam, lifting jack one end is connected on large arm, the other end is connected with development machine body, at least one longeron is installed on crossbeam, and longeron jack is connected between crossbeam and longeron.
The large arm of temporary support device of the present invention can be integral arms, can be also telescopic arm, and described crossbeam can be linear pattern beam, can be also shaped form beam.
Further, the present invention can also be provided with multiple rollers on the longeron of described temporary support device, and crawler belt is installed on roller.
The present invention is provided with accumulator on described temporary support device, and the pressure pocket of described lifting jack, longeron jack is communicated with accumulator.
Anti-deflection guide strip is installed on temporary support device, and described anti-deflection guide strip is arranged between longeron and crossbeam.
The present invention is also provided with top web storage on temporary support device.
Road heading machinery temporary support device of the present invention can, in road heading machinery coal cutting process, carry out lasting temporary lining to top board, does not need lifting temporary support device just can carry out the movement of road heading machinery.Use temporary support device of the present invention, can implement at road heading machinery rear permanent support operation, and then realize the parallel operations of pick anchor, increase substantially drivage efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of temporary support device of the present invention.
Fig. 2 is the plan structure schematic diagram of temporary support device of the present invention.
Detailed description of the invention
Temporary support device is arranged on development machine body 4, and its structure as shown in Figure 1 and Figure 2, is made up of large arm 1, lifting jack 5, crossbeam 3, longeron 2, longeron jack 7, roller 9, crawler belt 8, accumulator 10, top web storage 6, anti-deflection guide strip 11.Large arm 1 bottom and development machine body 4 are hinged, and top and crossbeam 3 are hinged, and lifting jack 5 is installed between the angle that large arm 1 and development machine body 4 form.Some longerons 2 are installed on crossbeam 3, several rollers 9 are installed on longeron 2, crawler belt 8 is installed on roller 9, and between longeron 2 and crossbeam 3, anti-deflection guide strip 11 is installed, longeron jack 7 is connected between crossbeam 3 and longeron 2.Between longeron 2 and crossbeam 3, due to the anti-deflection effect of anti-deflection guide strip 11, keep consistent with development machine direction of advance always, thereby be unlikely to damage longeron 2 because of deflection problem.Because longeron 2 and longeron jack 7 are hinged, run into back not at ordinary times, longeron 2 fore-and-aft directions swing, and make roller 9 and crawler belt 8 be close to top board.Because crossbeam 3 is hinged with large arm 1, when running into back left and right not at ordinary times, crossbeam 3 can swing at left and right directions, makes roller 9 and crawler belt 8 be close to top board.The pressure pocket of lifting jack 5, longeron jack 7 is communicated with the accumulator 10 being arranged on temporary support device, due to the pressure maintaining effect of accumulator 10, even if development machine driver operation level does not pass a test, cause between roof and floor while highly there is larger variation, each jack also can be always in pressure constant state, the crawler belt 8 of temporary support device is close to back all the time, the support force of top board is kept to relatively constant, thereby realized reliable temporary lining effect, temporary support device needn't be fallen can move forward with road heading machinery.
