Abstract

The utility model relates to an undercutting ballast scarifier, which belongs to the undercutting ballast scarifier of railway line maintenance equipment. The existing ballast scarifier is only applicable to a non-railroad-switch part, and the ballast scarifier of the type can not work at a crossed part. When the undercutting ballast scarifier works, firstly, the digging angle is regulated by a guide part, then, a chain wheel of a digging part drives a chain to rotate, ballast at the bottom part of a steel rail can be scarified out, and finally, the ballast is brought to a screen mesh part through a vehicle wheel device, and the digging mode is completely different from the digging mode of the existing ballast scarifier. The ballast is rotated to the bottom part through single-side digging beams, the defect that the ballast part can not be cleaned can be overcome, at the same time, the labor can be saved from the beginning to the end of the work, the size and the weight of a machine are also reduced, and in addition, the maintenance is convenient.

Description

Fragment-digging equipment at the bottom of a kind of pillow

Affiliated technical field

The utility model belongs to the railway track maintenance of equipment---pillow end fragment-digging equipment.

Background technology

Pillow end fragment-digging equipment is a kind of equipment that is used to claw ballast aggregate at the bottom of the rail iron sleeper on the cleaning car.The cleaning car claws the ballast aggregate of sleeper bottom by fragment-digging equipment, and the bucket wheel by the fragment-digging equipment next door screens cleaning roof on the ballast aggregate band to stone again, will screen good stone at last and put back at the bottom of the steel tie and tamp.

Existing fragment-digging equipment only is applicable to non-track switch place, and operation is more loaded down with trivial details, needs to take off chain during beginning and disconnects, and passes the rail below, and then connects, and also will take apart when finishing at last and take off chain.During work by the major and minor gear in the hydraulic motor driven gear case, pinion is passed to sprocket wheel with power again, take off chain movement thereby drive, take off on the chain taking off the palm and grilled teeth will rest the head on down ballast aggregate and take in the guide groove, be sent in the vibrosieve, vibrosieve passes through to screen, again be routed to the stone that sifts out under the sleeper, by tamping unit stone is made firm by ramming then,, guarantee traffic safety to improve track stability.Broken quarrel and dirty soil is through main dirty dust conveyer belt, turns round that dirty soil is transported to the circuit both sides or to dirty navy barrow.Take off chain and be in the pentagon cocycle campaign of a sealing, take off the longer dimension of chain, quite big to the load of gear, so sprocket wheel is also than being easier to wearing and tearing.The defective of this type of fragment-digging equipment maximum can not be located work at track switch exactly simultaneously, and rail must be in all the time to be taken off in the middle of the chain, runs into infall, and this type of fragment-digging equipment just can't be worked.In addition, when the taking off chain and internal fault occurs of this fragment-digging equipment, chain is heavy grow because of taking off, and dismounting, maintenance bother.

Summary of the invention

For overcoming above-mentioned all class defectives, the utility model provides a kind of new quarrel mode of taking off.Fragment-digging equipment is broken through original through mode and is changed plug-in type at the bottom of a kind of pillow, operating principle: hydraulic motor drives the drive sprocket fast rotational by main shaft, the chain that will be assembled together with drive sprocket, constraint by driven sprocket, make chain produce rapid movement, by rake teeth and the rake plate that is assembled on the chain stone is clawed from sleeper bottom again, thereby make fragment-digging equipment realize that it takes off the function of quarrel.In the fragment-digging equipment course of work, the tensioner oil cylinder is in the automatic tension state all the time, does not need after chain is elongated to adjust.

Technical scheme and basic structure:

The utility model utilizes above-mentioned operating principle, create the structure of the new fragment-digging equipment of a cover: have a guide frame that is connected with car load, what depend on guide frame is the foundation framework that whole working portion is installed, whole operating mechanism mainly is divided into two parts, the one, knuckle section, another is to excavate part, and knuckle section mainly is made up of tooth bar oil cylinder and a pair of gear, excavates part and mainly is made up of digging beam and sprocket wheel.Two groups of gear drives have been comprised in its structure.First group is to be rotated by the hydraulic motor driven gear, and final pulling is taken off the quarrel chain with sprocket rotation.Another group is that the control digging beam enters the gear of duty.When needs excavated, at first tooth bar oil cylinder piston bar motion drove the gear wheel motion, causes the rotation of whole end carriage, just end carriage is changed over to the sleeper bottom, realizes angular adjustment.The ballast aggregate that rotatablely moves sleeper bottom of chain takes the sleeper end to, takes ballast aggregate to screen portion by wheel assembly, and the excavation mode of this kind excavation mode and aforesaid fragment-digging equipment is different fully, and there has been very big progress the manual operation aspect.

Can change the anglec of rotation of excavating bottom girder and adapt to different sleeper extension elongations when track switch place length of sleeper diminishes or becomes big, the oil pressure that this operation only needs to regulate the tooth bar oil cylinder can be realized safe ready.

Beneficial effect of the present invention:

Rotate to the bottom by monolateral digging beam, solved the defective that the track switch place can not clear up, saved manpower at the whole story of work simultaneously, also alleviated volume, the weight of machine, and be convenient to maintenance.

Specific embodiment

As Fig. 1, Fig. 4, shown in Figure 6, before the work, drive foundation framework 2 by guide frame 3, fragment-digging equipment at the bottom of the whole pillow is moved down, bottom girder 6 is reached under the sleeper end.During work, hydraulic motor drives the driven sprocket 8 and the chain 9 (seeing Fig. 2, Fig. 3 and Fig. 5) that are contained on the end carriage 7 and carries out gyration by main shaft drives drive sprocket 1 fast rotational; With hour rack oil cylinder 4 effect, drive bottom girders 6 by the gears in the inner frame 5 10 and turn to, adjusting angle to sleeper incision down, claws ballast aggregate by rake teeth and the rake plate that is assembled on the chain 9 from the sleeper bottom, thereby makes fragment-digging equipment realize that it takes off the function of quarrel.Adjust the oil pressure in the tooth bar oil cylinder 4, can change the anglec of rotation of excavating bottom girder 6 and adapt to different sleeper extension elongations, just work at the track switch prescription.

Show among Fig. 1 that in the fragment-digging equipment course of work, the tensioner oil cylinder is in the automatic tension state all the time, do not need to adjust after chain 9 is elongated.

Shown in Figure 4, pressing plate 11, supporting base 12, dust cover 13 play fixing, dustproof effect to gear 10 in this pillow end fragment-digging equipment, guarantee effective work of tooth bar oil cylinder 4.

Shown in Figure 7, protection base 14 is that the digging beam lubricating oil pipe is protected, in order to avoid ballast aggregate is to pipeline damage.

Shown in Figure 6, the effect of gland 15 is to compress protection drive sprocket 1; Wearing plate 16 protects bottom girder 6 to prevent wearing and tearing in chain 9 courses of work; During 4 work of tooth bar oil cylinder, the pillow of stroke dog 17 control bottom girders 6 is the incision angle down, works when bottom girder 6 is parallel with sleeper; Junction plate 18 plays interconnect function at inner frame 5 and 6 of bottom girders.
