the utility model provides a propeller paddle is dismantled with drawing horse ware, is in including a supporting beam, setting supporting beam below elevating system and setting supporting beam top is used for the connecting piece of spacing chain, the chain is used for the bolt to draw propeller's paddle.

According to the technical scheme, the paddle is fixed by the chain and then is detached from the propeller under the driving of the lifting mechanism, and the supporting beam provides a supporting stress platform for the chain.

Preferably, the lifting mechanism is a jack, the bottom of the jack is welded with the support beam, and a gasket is arranged at the telescopic end of the jack. The telescopic end of the jack is inserted into a central hole in the propeller, the gasket increases the friction force between the telescopic end and the propeller, and the stability of the puller in the disassembling process is improved.

Preferably, the connecting piece is respectively and symmetrically arranged on the nuts at two sides above the supporting beam, and the central axes of the two nuts are on the same straight line. A chain is adopted, two ends of the chain are respectively fixed on two paddles, and a jack pulls down the paddles in the jacking process.

Preferably, the chain passes two nut settings respectively, just the both ends of chain are equipped with lobster button respectively. The lobster buckle facilitates the fixation of the paddle and is simpler and more convenient to operate.

Preferably, baffles are respectively arranged on the chains and on the inner sides of the screw caps. Improve the stability of the puller during application.

Preferably, a mounting hole is formed in the center of the supporting beam, the lifting mechanism comprises a screw rod penetrating through the mounting hole and an adjusting block in threaded connection with the screw rod, and the adjusting block is located below the supporting beam; and a limiting plate is arranged at the bottom of the screw rod, and a gasket is also arranged at the bottom of the limiting plate. The size of regulating block is greater than the size of mounting hole, and the lower extreme of lead screw is pegged graft in the centre bore of propeller, and the position of the supporting beam of adjustment makes supporting beam and regulating block contact, then presses supporting beam and makes it contact with the regulating block all the time together, rotates the regulating block and makes regulating block and supporting beam move up along the lead screw together, demolishs the paddle.

Preferably, the connecting piece is two nuts which are arranged on the supporting beam in parallel, and central axes of the two nuts are arranged in parallel.

Preferably, chains are respectively arranged in the two nuts, and the chains are annular. The annular chains are adopted to directly sleeve the symmetrical blades on the two sides respectively, so that the operation is more convenient.

Preferably, the support beam is a channel steel. The steel channel is adopted, so that the supporting capacity is strong, the jack is convenient to install, the hardness is high, and the stability is good.

The utility model has the advantages that:

the utility model overcomes current horse puller requires higher shortcoming to the force point, has realized the quick dismantlement to the propeller paddle.
