Abstract
Be used for railway and make the pillow electric tamper of ballast aggregate down firm by ramming, vibrating device is by constant speed, counter-rotational two vibrating shafts constitute each other.Maximum slotting vibration force down is two eccentric block centrifugal force sums, and the component of two eccentric block centrifugal force horizontal directions has then changed into the alternation couple, forms the pick palmar surface to resting the head on down the twisting vibration of ballast aggregate.Concrete vibrating mode uniqueness of the present invention, compact conformation, good rigidity, stable working is easy to lightweight, vibration efficiency height, and handgrip frame and damping device structure are rationally advanced.Be convenient to handle, improved surfaceman's operation posture and condition of labor.
Description
Be used for the m of w operation and make the pillow special-purpose machinery of ballast aggregate down firm by ramming.
In the prior art, mechanized maintenance book series " DDJ-300 type electric rammer " (publish by people's railway publishing house, in March, 1977.Standard book number 15043.6064) electric rammer that uses on the China railways all is by the dress eccentric block at motor rotor shaft one end.Eccentric block is the vibration force of electric rammer with the centrifugal force of rotor rotation, will rest the head on down the ballast aggregate tamping by pick plate, pick transmitting vibrations power.Its shortcoming:
The vibration force of the horizontal direction that eccentric block is vertical with pick plate center line, can only make body is that fulcrum is done the lateral oscillation vibration with the pick.Its result not only causes energy loss.And it is harmful to the operator.
Eccentric block with the vibration force of pick plate center line parallel direction.Because this power and pick plate center line have the distance of 50 millimeter.The mass cg of body is not also on the center line of pick plate in addition.Therefore in the process of vibrating the pick plate has been formed certain bending moment.Cause pick plate elastic bending deflection.Not only off-energy weakens the vibration force that the pick plate is transmitted.And be directed at pick plate fracture to the life factor.DZG-350 type electric rammer is an elasticity pick plate.350 kilograms of the specified perturbed forces of this machine (vibration force).Actual measurement is 272 kilograms.The verified seriousness of this problem.
The electric rammer of various models.Handgrip is horizontal in-line setting.Because body center of gravity.Far away from handgrip.Therefore it is very inconvenient to lift.Easily the pick plate must be inserted down to the pillow slanted floor during flicflac operation.The surfaceman will bend over obliquely firmly to advance.Operate very arduous.Since staff thrust direction and pick plate center line differ to.Thrust forms moment of flexure to the pick plate.Handgrip frame and body are again by the damping ring resilient connection.Therefore the macrobending state is serious more more for thrust.The transmission efficiency of people's both hands thrust is also low more.Be exactly because the effect of above-mentioned all factors.So the little difficult insertion railway roadbed of the vibration force of electric rammer, compact zone is little, tamping quality is low.
The objective of the invention is to eliminate the nuisance vibration power of electric rammer horizontal direction, and and then with its conversion, in order to improve tamping result and to improve surfaceman's condition of labor.
Technical scheme of the present invention is, the vibrating motor armature spindle, do not adorn an end of eccentric block.Be processed into gear.By gear drive, drive that gear shaft, diaxon that another root below it also is equipped with eccentric block want that rotating speed equates, the centrifugal force of switched in opposite and two eccentric blocks equates.The phase place of two eccentric blocks is identical during assembling.After rotor rotation is got up like this.The maximum centrifugal force of vertical direction is two eccentric block centrifugal force sums.And two eccentric block centrifugal force sums of horizontal direction just have been transformed into an alternation couple.With the tamping rod of this couple by straight down.The pick palm is to pillow ballast aggregate output twisting vibration down.By the pick palmar surface ballast aggregate is carried out vibration tamping.The vertical state work of body like this.The surfaceman also just directly waist operated.Two hands do not need to exert pressure to handgrip yet when making firm by ramming.
Characteristics of the present invention are the vertical state work of body when making firm by ramming.In the twisting vibration mode.Carry out vibration tamping to resting the head on down ballast aggregate.Pick is slapped the reaction force of a side line slag to pick palm vibration force.Being born by pick palm opposite side ballast aggregate, is not to go balance by the strength of body weight and machine top staff.Eliminated energy loss.Improved vibrating effect, stable working.
When inserting down, the maximum vibration power of vertical direction is the centrifugal force sum of two eccentric blocks.The pick pinnacle, pick palm thickness is less, again because the twisting vibration factor is arranged.Therefore slotting resistance is little down to make the pick palm stir ballast aggregate to its two side direction.On the other hand, the cross section because of tamping rod is a tubular.The compact rigidity of housing construction symmetry is big.Therefore to the transmission efficiency height of vibration force.The efficient of staff active force is also high, and the following ability of inserting of institute is strong.
The handgrip frame is that T shape symmetrical structure handgrip vertically is provided with.As Fig. 1, vibration absorber: adopt the damping ring vibration damping, so just can improve the relative position state of handgrip frame and body.Again because the body center of gravity is near from handgrip on the upper side.So the present invention is easy to use laborsaving.Can alleviate surfaceman's labour intensity.
Fig. 1 is the preceding diagrammatic sketch of electric tamper of the present invention.
Fig. 2 is that generalized section is looked on the right side of electric tamper of the present invention.
Optimum implementation of the present invention is.Pick (1), the pick palm (2) are welded on the lower end of tamping rod (3).The upper end is integrally welded with the stator casing (8) of motor by lower connecting plate (4), gusset (5), upper junction plate (6) and two end plates (7).
Rotor tooth wheel shaft (12) left side eccentric block (10) is connected and fixed by key (11).Left end dress bearing (13) reinstalls end cap (9).Right-hand member dress bearing (19), bearing support (17) reinstall flange (16).Gear shaft (20) left end dress bearing (19), bearing support (17) reinstall in the seat hole of axle box (23).Middle part eccentric block (22) is connected and fixed by key (11), and right-hand member dress bearing (19), bearing cover (21) use bolt (spring pad) (18) to be fixed on the right side of axle box (23) again.
In the middle of end cap (9) and axle box (23) were pressed in by its rim of the mouth, with stator casing (8) and flange (16), the bolt hole that is passed two end plates (7) by two cover bolts (nut, spring pad) (32) and two bolts (spring pad) (33) was connected and fixed.
Below the damping ring (36) four groups 20 by bolt (32,33) and support bar (35), cottor pin (34) support fixation, above two groups 8 be fixed on the bracing frame (14) of two end plates (7) lateral surface by bolt (nut, spring pad) (32) and went here and there the support bar (35) of axle bed (15) and cottor pin (34) and realize support fixation.
Grip (26) passes through axle (28), plain cushion (27) rivet clasp on axle bed (25).Wire clip (30), bolt (nut, spring pad) (29) with lead fixed on gusset (31).
