Abstract

The utility model provides a vertical digging device which comprises a bottom beam, an erect guide groove connected with both ends of the bottom beam, a supporting arm supporting on the inner side of the upper part of the erect guide groove, a digger chain circulating between the bottom beam and the erect guide groove, a drive wheel and a drive motor driving the digger chain. The utility model is characterized in that the bottom beam is designed into mutually sheathed telescopic bottom beams, the erect guide groove is designed into mutually sheathed telescopic guide grooves and the supporting arm on the inner side of the upper part of the erect guide groove is designed into mutually sheathed telescopic arms. Thus, the vertical digging device can change in no stages on height and bottom width and can simultaneously move left or right round a carriage so as to completely meet needs for digging ballast. All regulation is automatically completed by the machine with no need of manual regulation, so the utility model reduces workmen's labor intensity, raises work efficiency and provides a fast, high-efficiency and effective scheme as a solution for cleaning and screening a switch.

Description

A kind of vertical excavation device

Technical field

The utility model relates to a kind of excavating gear, and especially a kind of vertical excavation device that is used with screen scarifier belongs to railway machinery design and manufacturing technology field.

Background technology

At present, use the tilting excavating gear on the railroad ballast screen scarifier, its digging efficiency height, dependable performance.But when railway switch is carried out ballast cleaning, because the track switch width is greater than the rail width, need manually repeatedly to extend rake chain and bottom girder during cleaning, not only increase working strength of workers, but also time-consuming, do not satisfy, skylight time of short duration requirement big behind the train speed raising to the construction of railways amount.Therefore, be necessary prior art is improved.

Summary of the invention

Need excavate width with artificial lengthening for overcoming existing excavating gear, thereby bring labour intensity big, construction speed waits not enough slowly, and the utility model provides a kind of can increase or dwindle the excavation width automatically, reduces labour intensity, improves the vertical excavation device of efficiency of construction.

The utility model is realized by following technical proposal: a kind of vertical excavation device, comprise bottom girder, be connected the upright guides at bottom girder two ends, and the support arm that is supported on the upright guides upper inner, and circulate in the digger chain between bottom girder and upright guides and drive the driving wheel and the drive motors of digger chain, it is characterized in that bottom girder is arranged to the telescopic bottom girder of mutual socket, upright guides is arranged to the telescopic guide groove of mutual socket, and the support arm of upright guides upper inner is arranged to the telescopic arm of mutual socket.

The telescopic arm of described mutual socket is socketed to form by square interior pipe and outer tube, the upper end of interior pipe is fixed on upright guides top, the outer tube lower end is fixed on the vehicle frame, and oil cylinder is housed in the pipe in square, so that realize that under oil cylinder drives it is flexible, be provided with oil cylinder in the telescopic arm outside, be used to control the swing of telescopic arm, thereby the upper shed of control upright guides is big or little around the vehicle frame fixed point.

The upright guides of described mutual socket is socketed to form by square interior pipe and outer tube, is provided with oil cylinder in the outside of upright guides, is used to control the lifting of upright guides.

The telescopic bottom girder of described mutual socket is socketed to form by interior cover and overcoat, the upright guides bottom that is attached thereto at the bottom girder two ends is fixed four oil cylinders respectively, the other end of oil cylinder is separately fixed on the vehicle frame, by stretching of four oil cylinder control bottom girders, thereby control upright guides under shed is big or little.

The utility model compared with prior art has following advantage and effect: adopt such scheme, the setting of promptly flexible bottom girder, flexible upright guides, flexible support arm, can make the vertical excavation device in height, realize stepless variation on the bottom width, simultaneously can be around a vehicle frame left side or right displacement, the needs of ballast excavating have been satisfied fully, and all regulate all and itself finish automatically by machinery, need not artificial adjustment, both reduced working strength of workers, having improved operating efficiency again, is to solve track switch cleaning effective scheme fast and efficiently.
