The invention content is as follows:

the utility model aims at providing a hydraulic turbine runner transportation buffer stop.

The above purpose is realized by the following technical scheme:

the utility model provides a hydraulic turbine runner transportation buffer stop which constitutes includes: the horizontal section of the anti-collision box body is of a T-shaped cavity structure, wherein the anti-collision box body consists of an upper leakage-stopping ring storage cavity and a lower leakage-stopping ring storage cavity, the length of the upper leakage-stopping ring storage cavity is greater than that of the upper leakage-stopping ring storage cavity, and the upper leakage-stopping ring supporting assembly is installed at the bottom of the upper leakage-stopping ring storage cavity;

the upper stop leakage ring supporting assembly consists of a supporting vertical plate, a base plate and rib plates, the supporting vertical plate and the base plate are vertically welded and fixed, bolts are inserted into mounting holes in the base plate to fixedly connect the base plate with the bottom of the anti-collision box body, and the rib plates are arranged on two sides of the supporting vertical plate;

the anti-collision box is characterized in that two sides of the outer box body of the anti-collision box body are vertically connected with lug plates, and steel wire rope insertion holes are formed in the lug plates.

In the anti-collision device for the transportation of the water turbine runner, the upper stopping leakage ring of the water turbine runner is placed on the upper stopping leakage ring supporting component on the upper stopping leakage ring storage cavity;

the lower leak-stopping ring is stored in the cavity and is prevented from being provided with the lower leak-stopping ring of the water turbine runner.

The hydraulic turbine runner transportation buffer stop, buffer liner of the cotton material of pearl has been placed between crashproof box and the hydraulic turbine runner.

The utility model has the advantages that:

1. the utility model discloses when transporting hydraulic turbine runner, at first place hydraulic turbine runner transportation buffer stop on the low flat board of low dull and stereotyped trailer, then pass the wire rope jack of the otic placode on the anticollision box with wire rope's one end, wire rope's the other end is fixed on the hitch on the low flat board, fix the anticollision box on the low flat board of low dull and stereotyped trailer this moment, then hoist the steam turbine runner, prevent two internal top stop leak ring supporting component of anticollision box with hydraulic turbine runner, top stop leak ring supporting component's support riser is supported the stop leak ring on the hydraulic turbine runner, the lower stop leak ring of anticollision box is placed in the cavity is deposited to the stop leak ring down, the bottom supports through the bottom plate of anticollision box, then fully fills through the cushion pad with the space between hydraulic turbine runner and the anticollision box, accomplish the work of packing into the anticollision box of runner, at last carry out the secondary in the fixing of hydraulic turbine runner through wire rope, transport the hydraulic turbine runner through low dull and stereotyped trailer.

The utility model has the advantages of being simple in structure and convenient in operation, through setting up hydraulic turbine transportation anticollision box, can make the hydraulic turbine runner be vertical structure and place, avoid when horizontal transportation hydraulic turbine runner, the lower leak-stopping ring of hydraulic turbine runner extends the both ends of low link plate, sets up the anticollision box simultaneously and can prevent when transporting the hydraulic turbine runner, because what emergency brake produced is used to and makes the hydraulic turbine runner roll, has improved the security of hydraulic turbine runner greatly.
