Abstract
A small hydraulic tamping tool comprises a pillar (2), an oil tank (4), an oil pump (6), a beam (7), an elevation oil cylinder (8), a motor (9), a locked oil cylinder (10) and a pick plate (14); the tamping tool is characterized in that the tamping tool also comprises a vibration device; the vibration device comprises a vibration frame (3) and a vibration motor (11); the vibration frame (3) is connected with the bottom of the oil tank (4); the vibration motor (11) is arranged in the vibration frame (3), the cantilever shaft on both sides of the vibration frame (3) is equipped with the pick plate (14). The utility model can remove the problems of the belt skid, the eccentric wearing, the belt losing and the snap etc., caused by the reduced central distance between two band wheels and that the two band wheels are not in the same plane, so the working efficiency is increased.
Description
One, technical field
The utility model belongs to a kind of tamping machine of railway track maintenance operation, particularly relates to a kind of light hydraulic tamping machine.
Two, background technology
The light hydraulic tamping machine of present domestic use (comprising main track and track switch) is mainly by frame: it comprises underframe, guide pillar and crossbeam, Hydraulic Power Transmission System: it comprises oil pump, reversal valve, hoist cylinder, consolidated oil jar and fuel tank, tamping equipment: its involving vibrations framework and tamping pickaxe.The sliding sleeve at fuel tank two ends matches with the guide pillar of frame, and links to each other by the crossbeam of hoist cylinder with fuel tank and frame.Motor mounting is on fuel tank, bottom surface at fuel tank, link to each other with vibration frame by rubber shock absorber, eccentric iron sheet belt wheel is installed on the power transmission shaft at vibration frame center, motor drives eccentric iron by V-belt and belt wheel and rotates, every side cantilevered axle of vibration frame is all installed a pair of tamping pickaxe plate, and the two pick plates upper end of homonymy is equipped with consolidated oil jar, and the centre is equipped with synchronizing bar.In the course of work, motor drives oil pump simultaneously and eccentric iron rotates, and on the one hand eccentric iron rotates, and makes vibration frame produce vibration, drive the pick panel vibration, on the other hand, the oil pump pressure oil output is by reversal valve control hoist cylinder and consolidated oil jar, make the pick plate can carry out lifting, open the folder action, ballast aggregate under pick panel vibration power and folder strength effect, fill up smoothly and closely knit pillow under, finish tamping operation.Tamping tool is being inserted down in the process, be subjected to the resistance of ballast aggregate, rubber shock absorber pressurized and produce distortion, cause that center to center distance reduces between motor and eccentric iron two belt wheels, four rubber shock absorbers are being subjected to the resistance difference in the slotting process down in addition, thereby the compressive strain that produces is unequal, two belt wheels are coplane not, though between two belt wheels regulating wheel is installed, it can only improve the tensioning degree of belt in limited range, in tamping operation, belt creep causes that transmitted power descends, and influences tamping quality, the belt eccentric wear, fall band and fracture, increase the maintenance work of machinery, influence efficiency of operation.
Three, summary of the invention
The utility model technical issues that need to address are: a kind of light hydraulic tamping machine is provided, it can eliminate owing to the reducing of two center distance of belt wheel, not the belt creep, the eccentric wear that produce of coplane, fall band and problem such as fracture, improve operating efficiency.
Technical solution of the present utility model is: light hydraulic tamping machine, comprise guide pillar, fuel tank, oil pump, crossbeam, hoist cylinder, motor, consolidated oil jar and pick plate, it goes back the involving vibrations device, described vibrating device comprises: vibration frame, vibrating motor, described vibration frame links to each other with the bottom surface of fuel tank, in this vibration frame vibrating motor is installed, on the cantilevered axle of described vibration frame both sides the pick plate is installed.
The utility model compared with prior art has following advantage: because novel light hydraulic tamping machine is to utilize vibrating motor to replace original motor, drive eccentric iron by the band transmission and rotate the generation vibration force, eliminated transmitted power decline in the tamping tool work, vibration force reduces, thereby improve the quality and the operating efficiency of tamping operation, also eliminated simultaneously because the maintenance works such as replacing belt that belt falls band and fractures and brought, alleviate working strength of workers, enhanced productivity, reduced operating cost.
Four, description of drawings
Fig. 1 is the front view of the utility model light hydraulic tamping machine;
Fig. 2 is the utility model partial enlarged drawing.
Five, specific embodiments
Two guide pillar 2 upper/lower terminals are threaded to one with crossbeam 7 and underframe 1 usefulness respectively and form frame, the sliding sleeve at fuel tank 4 two ends matches with guide pillar 2, slide up and down, ring Xiao on hoist cylinder 8 cylinder bodies is hinged with the supporting seat that is fixed on the fuel tank 4, hoist cylinder 8 piston rod ends are fixed on the crossbeam 7 with ball pivot, motor 9 and oil pump 6 are installed on the upper cover plate of fuel tank 4, and use the V-belt transmission.Bottom surface at fuel tank 4, link to each other with vibration frame 3 by four rubber shock absorbers 13, the center of vibration frame 3 is equipped with vibrating motor 11, pick plate 14 is installed on the cantilevered axle of vibration frame 3 both sides, the piston rod of pick plate 14 upper ends and consolidated oil jar 10 is hinged, and consolidated oil jar 10 cylinder barrels are hinged with the earrings 12 that is fixed on the vibration frame 3, during hoist cylinder 8 work, can drive fuel tank 4, vibration frame 3, pick plate 14 and consolidated oil jar 10 are along on the guide pillar 2, lower slider, and during consolidated oil jar 10 work, make pick plate 14 around cantilevered axle swing, realize opening and press from both sides reality of pick.
Connect power supply, motor 9 drives oil pump 6 rotations, oil pump 6 pressure oil output, by multiple directional control valve 5 control hoist cylinder 8 and consolidated oil jars 10, realize the lifting of pick plate 14 and open folder, meanwhile, the vibrating motor 11 that is installed in vibration frame 3 centers makes pick plate 14 produce 4000 times/min, the vibration force of 24KN.After the pick plate 14 of vibration inserted railway roadbed, ballast aggregate was vibrated, and mutual frictional force reduces or is overcome, and occurs " flow regime ", and ballast aggregate rearranges closely knit in relative motion, at pick plate 14 folders in real time, filled up pillow space down, reached the purpose of making firm by ramming.
