Description
The present invention relates to the machinery that a kind of underground pipeline or similar engineering build particularly adopts the method for vibration or vibration compacting that place, the underground pipeline thoracic cavity soil of building is carried out closely knit machine.
Current domestic underground pipeline construction amount is big, and one of reason that has a strong impact on the underground pipeline engineering quality is that in the construction banket and can not reach the compacting requirement in the pipeline thoracic cavity, has influenced the basis of later body, workmanship has been caused the consequence of bad redemption.
The patent documentation SU1520185 that obtains one piece of Soviet Union by retrieval discloses the compacted rammer compacter of a kind of pipeline thoracic cavity place's soil body, it comprises that rammer frame, rammer frame are " Jiong " shape, ram the frame both sides and establish shaker arm, each shaker arm lower end is connected to the vibro-rammer body, the vibration of vibrator reaches the vibro-rammer body by rammer frame, shaker arm, the vibro-rammer body is a slabbed construction, has realized place, pipeline thoracic cavity is vertically tamped.This technology has solved the alternative problem of manually tamping under pipe trench.But remain in following shortcoming: (1) said structure can not produce the horizontal normal pressure that armpit angle, thoracic cavity II (referring to Fig. 1) is located, and can only vertically tamp, and can't be real to the soil water straight tamper at II place, armpit angle; (2) owing to its structures shape, so this vibration source can't produce vibration.In sum, this patented technology still can't solve the soil compaction problem at II place, armpit angle, pipeline thoracic cavity.
The objective of the invention is to design and a kind ofly have the shape of a hoof and ram frame, ram the frame both sides and be provided with the rammer compacter that shaker arm, shaker arm lower end are provided with the new construction of two vibro-rammer bodies, can solve the soil compaction at II place, armpit angle, pipeline thoracic cavity.
The present invention is achieved in that this rammer compacter mainly forms by ramming frame and vibro-rammer body, and the rammer frame is made the shape of a hoof, respectively adorns a vibro-rammer body in both sides, so that carry out tamping operation simultaneously in the pipeline both sides.Because of banketing of II place, armpit angle, body thoracic cavity also needs compacting, i.e. level compacting, so the vibro-rammer body can be rotated to an angle, the direction of ramming the body vibration force changes thereupon, to be fit to the needs of different occasions.Ram in the body and be provided with two eccentric blocks, crankshaft rotating makes them produce in-plane displancement, by being fixed on the flat spring between eccentric block and the vibrating mass, the vibration of drive vibrating mass, bent axle is made of two semiaxis, respectively be provided with a crank throw and adjust the relative angle of two crank throws, can realize ramming the compound motion of the pure vibration of body, pure vibration during rotation.
Below in conjunction with drawings and Examples the present invention is further described.
