Abstract

The utility model discloses a feeding device for a cleaning machine for pipelines used for cleaning pipelines, comprising a casing, a key, an eccentric shaft, small shafts, a roller, etc., wherein, the both ends of the small shafts and the eccentric shaft are arranged in the corresponding holes of the casing and a cover, and the two small shafts and the eccentric shaft are provided with rollers respectively. During cleaning, when a flexible shaft is stopped and is not able to move forward, the key is rotated to change the eccentric position of the eccentric shaft to clamp the flexible shaft to accomplish strong feeding. The utility model which has the advantages of simple operation, labor saving and big and uniform clamping force improves the working condition of the flexible shaft and prolongs the life time of the flexible shaft.

Description

Fedding Machine for cleaning pipe

The utility model relates to a kind of feed arrangement of tube cleaning.

The present pipeline cleaning instrument that uses, be steel pipe is surrounded "

" shape, flexible axle therefrom passes and puts in the pipeline and clears up, and when running into hard thing and stop up, flexible axle spins, and comes to a halt; At this moment screw is screwed in the screwed hole on the tube wall and clamps flexible axle, send to carry out brute force.The shortcoming of this badger is manually to loosen, tighten screw continually, wastes time and energy, and fragile flexible axle influences service life.

The purpose of this utility model is the tube cleaning feed arrangement for a kind of clamping flexible axle of being made up of three rollers that overcomes that above-mentioned weak point designs.

The utility model content, the tube cleaning feed arrangement is made up of housing ［ 1 ］, key ［ 3 ］, lid ［ 6 ］, eccentric shaft ［ 2 ］, little axle ［ 9 ］, roller ［ 5 ］ and ［ 8 ］; The two ends of little axle ［ 9 ］ and eccentric shaft ［ 2 ］ are installed in the respective aperture of housing ［ 1 ］ and lid ［ 6 ］; On the little axle ［ 9 ］ roller ［ 8 ］ is housed, on the eccentric shaft ［ 2 ］ the cylindrical car being housed there is the roller of groove ［ 5 ］; Eccentric shaft ［ 2 ］ end is milled with flat horizontal surface ［ 4 ］.

The utility model advantage is compared with existing badger, and the utility model utilizes three rollers to clamp flexible axle, has one to be sleeved on the eccentric shaft in three rollers; The groove of key bottom and eccentric shaft mill flat plane and match; The turn key, the eccentric position of change eccentric shaft can clamp flexible axle realization brute force and send the cleaning pipeline to; Easy and simple to handle, laborsaving, clamping force is big and evenly, therefore not fragile flexible axle has prolonged service life.In addition, the utility model compact overall structure, volume are little.

Below in conjunction with description of drawings the utility model embodiment, flexible axle ［ 10 ］ stretches out along the hole ［ 7 ］ that cylinder ［ 12 ］ inwall is coiled in cylinder ［ 12 ］ lining and passes the tube cleaning feed arrangement, cylinder ［ 12 ］ two ends are provided with bolster, this bolster is contained in support ［ 11 ］ lining, and handgrip ［ 13 ］ is installed on its right-hand member bolster; The tube cleaning feed arrangement is loaded on the left end of support ［ 11 ］, and coaxial with cylinder ［ 12 ］; Housing ［ 1 ］ and lid ［ 6 ］ go up each line boring require coaxial, can rotate flexibly behind guarantee to pack into little axle ［ 9 ］ and roller ［ 8 ］, eccentric shaft ［ 2 ］ and the roller ［ 5 ］; Roller ［ 5 ］ the cylindrical groove of having got on the bus has improved and the contacting of flexible axle ［ 10 ］, and has increased clamping force.The relative two sides, end of eccentric shaft ［ 2 ］ respectively mills out flat horizontal surface ［ 4 ］, matches with the groove of handgrip ［ 3 ］ bottom; During the cleaning pipeline, rotate handgrip ［ 13 ］, flexible axle ［ 10 ］ advances along pipeline, when flexible axle ［ 10 ］ runs into hard thing in pipeline, advances when being obstructed, and flexible axle ［ 10 ］ spins on the spot and can not advance; At this moment, only need move key ［ 3 ］ makes eccentric shaft ［ 2 ］ can clamp flexible axle ［ 10 ］ at flexible axle ［ 10 ］ direction increase offset, the realization brute force is sent the cleaning pipeline to, because roller ［ 5 ］ and ［ 8 ］ have certain-length, so clamping force is big and flexible axle ［ 10 ］ is stressed evenly, has prolonged the life-span; The below at the center that is centered close to the tube cleaning feed arrangement in hole ［ 7 ］ is with the volume and the appearance and size of dwindling the tube cleaning feed arrangement, compact conformation.
