Description

Coupler for tamping pickaxe

Technical Field

The utility model relates to a shaft coupling, concretely relates to a shaft coupling for tamping pickaxe reduces the transmission shake and the big shaft coupling of transmission torque.

Background

The tamping pickaxe is one of common tools in railway construction, the existing internal combustion engine tamping pickaxe adopts a gasoline engine as power, the gasoline engine is positioned between two handles at the upper part and is connected and transferred with a pickaxe body at the lower part through a universal joint. However, in the existing tamping pickaxe structure, the universal joint part is easy to damage, the torque is limited when power is transmitted, the buffering function is not provided, and the operator shakes greatly and is easy to fatigue when holding the handle.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem that exists among the prior art, provide a shaft coupling for tamping pickaxe.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a tamping pick is with shaft coupling which characterized in that: comprises an I-shaped shaft and two shaft rings which are respectively arranged at the upper end and the lower end of the I-shaped shaft; shaft holes are formed in the two sides of the upper part and the lower part of the I-shaped shaft; the shaft collar is a rubber ring, four embedded blocks are equiangularly arranged in the shaft collar, axial fixing bolt holes are formed in the two opposite embedded blocks, and the fixing bolt holes are matched with shaft holes in the I-shaped shaft; the remaining two blocks are provided with radial fixing holes which are respectively matched with the driving shaft and the driven shaft.

Further: the embedded block is a metal block and is integrally vulcanized, molded and connected.

Further: the inner hole of the collar is matched with the driving shaft and/or the driven shaft.

Further: the fixing holes are matched with the driving shaft and the driven shaft respectively through bolts.

The utility model has the advantages that: the utility model discloses simple structure, simple to operate is swift, can be fine after the installation transmit the transmission shaft and then transmit the pickaxe operation of tamping with the power of internal-combustion engine, because of the axle collar itself is the rubber ring, the accessible warp and absorbs certain energy, consequently, when producing vibrations and less displacement change, absorption compensation that can be fine, simultaneously, the compensation process is mild, can make the vibrations of operating personnel handle part feel diminish and become soft, has improved the travelling comfort of operation.

The sequence numbers in the figures illustrate: 1 is the I-shaped shaft, 2 is the axle collar, 3 is the shaft hole, 4 is the abaculus, 5 is the fixing bolt hole, 6 is the fixing hole.

Detailed Description

As shown in fig. 1-2, the coupler for a tamping pickaxe of the present invention comprises an i-shaped shaft 1 and two shaft collars 2 fixed on the upper and lower ends of the i-shaped shaft respectively through bolts; shaft holes 3 are formed in the two sides of the upper part and the lower part of the I-shaped shaft; the shaft collar is a rubber ring, four embedded blocks 4 are equiangularly arranged in the shaft collar, axial fixing bolt holes 5 are arranged on the two opposite embedded blocks, and the fixing bolt holes are matched with shaft holes in the I-shaped shaft; the remaining two blocks are provided with radial fixing holes 6, and the fixing holes on the upper and lower shaft rings are respectively matched with the driving shaft and the driven shaft.

Wherein: the inserted block be the metal block, inlay and establish in the inside of rubber shaft collar and be connected with the integrative vulcanization shaping of shaft collar, the inserted block can be inseparabler with bolt fit, provides bigger fastening force. To improve its adhesion strength, the thickness of the rubber may be increased outside the insert.

Wherein: the inner diameter of the shaft collar is matched with the driving shaft and/or the driven shaft, and the shaft collar is sleeved on the outer side of the shaft.

Wherein: the fixing hole is matched with the stepped hole and can be matched with the inner hexagon bolt, so that the bolt cannot exceed the outer surface, and the rotation problem cannot be caused. And bolts in the fixed holes are respectively matched with threaded holes in the driving shaft and the driven shaft to fixedly connect the shaft collar with the shaft. The inner bore diameter of the shaft collar is matched with the outer diameter of the shaft, and the part, facing one side of the shaft, of the embedded block where the fixing hole is located is arc-shaped, so that the embedded block is conveniently and tightly matched with the shaft.

The assembly and the use process of the structure of the utility model are as follows, the two shaft rings are respectively arranged at the upper end and the lower end of the I-shaped shaft and are fixed together by bolts; the transmission shaft of the internal combustion engine of the tamping pickaxe is fixedly connected with the upper side shaft collar through a bolt, and the transmission shaft is fixedly connected with the lower side shaft collar through a bolt, so that the installation and the fixation of the coupler are realized. In the use, can be fine transmit the transmission shaft and then transmit the pick with the power transmission of internal-combustion engine and carry out the tamping operation, because of the axle collar itself is the rubber ring, the accessible warp and absorbs certain energy, consequently, when producing vibrations and less displacement change, absorption compensation that can be fine, simultaneously, the compensation process is mild, can make the vibrations of operating personnel handle part feel diminish and become soft, has improved the travelling comfort of operation.

The present invention has been described in detail with reference to the preferred embodiments. However, variations and additions to the embodiments will become apparent to those of ordinary skill in the art upon a reading of the foregoing description. It is the intention of the applicant that all such variations and additions fall within the scope of the invention as claimed.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless otherwise defined, all terms (including technical and scientific terms) used herein are the same as commonly understood by one of ordinary skill in the art to which this invention belongs.
