Abstract

The utility model relates to a power-drive tamper, belonging to the tamping machinery of a building or road building aspect. The utility model is mainly characterized in that the power-drive tamper takes two identical anti-vibrating double-shaft extending motors whose power is 1-4KW and whose motor shells are integrated as power. A pair of synchronous gears are provided between the two anti-vibrating double-shaft extending motors to drive eccentric blocks which are directly installed on two extending ends of motor shafts, and a vibrating body is formed. The vibrating body and the power-drive tamper are connected rigidly, and are slanted for a definite angle. When the power-drive tamper runs, the two anti-vibrating double-shaft extending motors simultaneously inwards rotate to drive the eccentric blocks, which makes the vibrating body generate longitudinal exciting force, and a tamped object is tamped by a tamping body. Due to the fact that the vibrating body and the tamping body are slanted for the definite angle, when running, the power-drive tamper has horizontal component force, and the power-drive tamper forward runs depending on the horizontal component force.

Description

Power-drive tamper

The utility model is a kind ofly to be used to build or the ballast consolidating machine of the aspect of building the road.

At present, the rammer compacter that is used for constructing, great majority adopt a common motor or internal combustion engine to drive an eccentric block that is installed in the casing by belt and produce vibration, between motor or internal combustion engine and the rammer body good vibration absorber need be arranged, complex structure, poor reliability like this, by belt transmission, power loss is big, can only drive by unit, compacting power is little; Chinese patent CN85101705A reversing motor-driven tamper adopts two twin shafts to stretch motor, the eccentric block that driving is directly installed on the shaft extension two ends produces vibration, but because motor and the parallel connection of rammer body are a motor operation substantially during operation, another does not change, efficient is lower like this, turn round simultaneously as two-shipper, can only tamp in the original place, can not walk, and operation is unstable, and practicality is little.

The purpose of this utility model provides a kind of double motor and turns round simultaneously, can be voluntarily, and compacting power is big, the electric rammer of good reliability.

The casing that it is 1～4KW that main feature of the present utility model has been to adopt two identical power is that the twin shaft of one is stretched the anti-motor that shakes, link to each other by intermeshing synchromesh gear between the two motors, drive is directly installed on four eccentric blocks at motor shaft extension two ends, forms vibrating body.Vibrating body is rigidly connected with ramming body by flange, and 5～20 degree that tilt.

The advantage of this machine is: two motor inwardly rotations simultaneously when 1, moving, drive four eccentric blocks, make vibrating body produce exciting force longitudinally, because this power is by the two motors generation of turning round simultaneously, exciting force than monomotor or internal combustion engine generation is twice, can make the also corresponding increasing of compacting power of rammer compacter, improve efficient; Because the motor that adopts is the anti-motor that shakes, under strong vibration, can guarantee reliablely, improved reliability and life-span; Owing to link to each other by a pair of synchromesh gear between the two motors, guarantee two motors run-in synchronism, make the rammer compacter operation more steady.

2, vibrating body and rammer body are rigidly connected, and the inclination certain angle, and rammer compacter has a horizontal component during operation, can make rammer compacter walking forward voluntarily by this power, bi-motor was turned round simultaneously produced big compacting power, have solved problem voluntarily again.

3, this machine only is made up of vibrating body, rammer body, handrail and vibration insulating system, and structure is simpler.

Below by accompanying drawing, center of the present utility model technology contents is done to introduce in detail further.

Fig. 1 is the elevation of electric rammer.

Fig. 2 is the top view sectional drawing of electric rammer.

With reference to Fig. 1,2, stretch motor 10, a pair of synchromesh gear 9 and eccentric block 8 by two identical anti-twin shafts that shake and constitute vibrating body 5.The casing of two motors 10 is integral by welding or cast steel or cast iron.A pair of synchromesh gear 9 be contained in the motor casing and 10 on two motor on, be meshing with each other, guarantees that 10 runnings of two motor are synchronous.4 eccentric blocks 8 are equipped with at motor shaft extension two ends, are fixed in motor 10 axle heads by key and nut.Vibrating body 5 is rigidly connected with ramming body 7 by flange 6, and gradient is 5～20 degree.Case 4 is contained in and rams on the body 7, with vibrating body 5 sealings.Shock-absorbing spring 3 is contained between case 4 and the pressing plate 2, and handrail 1 is contained on the pressing plate 2.

Claims

1, a kind of electric rammer, used two identical power of electric motor are every 1～4KW, it is characterized in that this machine twin shaft that two identical casings are arranged is one stretches the anti-motor 10 that shakes, eccentric block 8 directly is contained in the two ends of motor shaft extension, and formation vibrating body 5, for being rigidly connected, its gradient is 5～20 degree between vibrating body 5 and the rammer body 7.

2, it is characterized in that according to the described electric rammer of claim 1, the synchromesh gear 9 of pair of meshing is housed between two motors.
