Abstract

The utility model relates to a hand-held internal combustion oscillatory type tamping pickaxe. A conventional internal combustion tamping pickaxe has the disadvantages of short service lifetime, loud noise and bad hand feeling of operators, etc. The utility model thus provides the hand-held internal combustion oscillatory type tamping pickaxe which has the characteristics of long service lifetime, low noise and good hand feeling of operators. The hand-held internal combustion oscillatory type tamping pickaxe in the utility model comprises a control handle, an internal combustion engine, a connecting seat, a gear box, a damping pad tube, a rubber spring, an adapting tube, a sleeve, a pick, an eccentric shaft, a flexible shaft and a housing. The upper end of the eccentric shaft is equipped inside the inner chamber of the sleeve. The control handle is connected with the damping pad tube. The input gear shaft of the gear box is equipped inside the connecting seat. One end of the input gear shaft of the gear box is an inner concave cylindrical face which cooperates with a centrifugal swing block on the main shaft of the internal combustion engine. The flexible shaft is equipped inside the inner chambers of the rubber spring and the adapting tube. A shaft joint on the flexible shaft is connected with the output shaft of the gear box. A lower joint on the flexible shaft is connected with the eccentric shaft.

Description

Hand-held internal combustion vibrating type tamping pickaxe

Technical field

The utility model belongs to railway line maintenance and uses field of work machines, particularly a kind of hand-held internal combustion vibrating type tamping pickaxe.

Background technology

Along with the high speed development of domestic railway, train travel density heightens, and rail track safeguards that the development trend that adopts large-scale tamping car and small-sized portable tamping pickaxe to carry out coordinating operation has become inevitable.At present, portable tamping pickaxe commonly used on the line generally has electronic tamping pickaxe and internal combustion tamping pickaxe, and electronic tamping pickaxe needs configuration power supply separately, and the scope of application is restricted; The internal combustion tamping pickaxe has and not influenced by power supply; Maneuverability, advantage such as in light weight; But owing between the output shaft of reducer and eccentric shaft, is connected in the existing internal combustion tamping pickaxe through power transmission shaft, the shortcoming that the violent vibration of tamping pickaxe in use causes power transmission shaft to damage causing tamping pickaxe to be lacked application life easily, in addition; It is big that existing internal combustion tamping pickaxe also exists noise, the weak point of operator's feel difference.

Summary of the invention

The utility model is short existing above-mentioned application life in use to existing internal combustion tamping pickaxe, and noise is big, and operator's feel is poor; Weak points such as labour intensity is big; A kind of long service life is provided, and noise is little, the hand-held internal combustion vibrating type tamping pickaxe of operator's good hand touch.

The technical scheme that the utility model adopts is accomplished through following mode: a kind of hand-held internal combustion vibrating type tamping pickaxe; It comprises control handle, internal combustion engine, Connection Block, speed-changing gear box, beam pipe, rubber spring, transfer tube, sleeve, pick, eccentric shaft, flexible axle and outer cover, and internal combustion engine, Connection Block, speed-changing gear box, beam pipe, rubber spring, transfer tube, sleeve and pick join successively; The eccentric shaft upper end is contained in the barrel bore through bearing; Control handle is connected with the beam pipe through clip; The input gear shaft of speed-changing gear box is installed in the Connection Block through bearing, and an end of speed-changing gear box input gear shaft is that the indent cylinder is planar, matches with centrifugal block for clutch use on the internal combustion engine main shaft; Outer cover and clip are connected, and outer cover plays dustproof effect; Flexible axle is made up of universal coupling, steel wire axle and shaft coupling, and wherein, universal coupling is to be formed by connecting through cross axle top connection and lower contact; Steel wire axle is to be wound in a shape by steel wire to form, and flexible axle is located in the inner chamber of rubber spring and transfer tube, and the shaft coupling on the flexible axle and the output shaft of speed-changing gear box join; Lower contact and eccentric shaft on the flexible axle join; Flexible axle plays the transferring power effect, drives the eccentric shaft rotation, makes eccentric shaft produce vibrations; Be convenient to tamping pickaxe and play shake, can also effectively prolong bearing life simultaneously.

In described hand-held internal combustion vibrating type tamping pickaxe, between clip and beam pipe, be provided with beam.

In described hand-held internal combustion vibrating type tamping pickaxe, put at control handle and to be provided with sponge tube, sponge tube plays anti-skidding and effect damping.

In described hand-held internal combustion vibrating type tamping pickaxe, on control handle, be provided with the I. C. engine oil door switch, the throttle size of controlling combustion engine.

In described hand-held internal combustion vibrating type tamping pickaxe, safety switch is housed on internal combustion engine,, emergency presses safety switch when taking place, and tamping pickaxe can be shut down at once, and operator's safety is played guaranteeing role.

During use; Starting apparatus combustion engine is stirred the output speed of the Oil Switch adjustment internal combustion engine on the control handle, and the centrifugal block for clutch use of internal combustion engine bottom is pressed under centrifugal action on the indent face of cylinder of input gear shaft of speed-changing gear box; Through the frictional force between contact surface the power of internal combustion engine is input to speed-changing gear box; Output shaft by speed-changing gear box is delivered to flexible axle again, and flexible axle lower end universal coupling drives the eccentric shaft rotation, under action of centrifugal force, knocks sleeve in the eccentric shaft rotation process; Make sleeve drive pick and produce vibrations, make function firm by ramming thereby make tamping pickaxe possess vibrations.
