Description

Hoisting tooling for guide vane assembly of hydro-generator set

technical field

The utility model belongs to the technical field of installing tooling for hydraulic generator sets, in particular to a guide vane assembly and hoisting tooling for hydraulic generator sets.

Background technique

At present, the guide vane body is an important component of the hydroelectric generator set. In the prior art, the guide vane body is generally installed by winding and hoisting a steel wire rope. To hoist the guide vane body with a steel wire rope, the center of gravity of the guide vane body needs to be determined first to ensure The guide vane body will not shift and fall during the hoisting process. To determine the center of gravity of the guide vane body requires repeated adjustments by the operator. This process is time-consuming and laborious, which seriously affects the installation speed of the guide vane body and low work efficiency. The outlet edge of the guide vane body has a sharp edge, and the weight of each guide vane body often exceeds 1 ton. During the hoisting process of the guide vane body, the wire rope used to wind the guide vane body is easily damaged by the sharp edge of the guide vane body. The cutting edge of the guide vane body will be cut off, which will cause the guide vane body to fall and be damaged, and the amount of steel wire rope will increase, which will increase the production cost of the hydroelectric generator set. Serious consequences and extremely high potential safety hazards.

In order to solve the technical problems in the known technology, the utility model provides a hydraulic generator set guide vane assembly and hoisting tool which is simple in structure, easy to use, can improve production efficiency, reduce production cost, and can effectively eliminate potential safety hazards.

The technical solution adopted by the utility model to solve the technical problems in the known technology is: a hydraulic generator set guide vane assembly hoisting tool, which is characterized in that: it includes a spiral pull rod with a drag hook at one end, and the other end of the spiral pull rod is Threaded rod, nuts are installed on the threaded rod of the screw rod, the screw rod is connected with the clamp body with a through hole, and the pull hook of the screw rod and the nut installed on the threaded rod are respectively located on both sides of the through hole, and the clamp body is hinged There are lug pressure rods.

The utility model can also adopt the following technical solution: the clip body includes a tie rod connection part and a lifting lug connection part, and a hook groove is formed between the tie rod connection part and the lifting lug connection part.

One end of the lifting lug pressing rod is provided with a lifting hole, and the other end is an arc structure.

The advantages and positive effects of the utility model are: because the utility model adopts the above-mentioned technical scheme, it includes a spiral pull rod with a drag hook at one end, the other end of the spiral pull rod is a threaded rod with a nut, and the spiral pull rod is connected with a through hole. The clip body is connected, and the pull hook of the screw rod and the nut installed on the threaded rod are respectively located on both sides of the through hole, and the clip body is hinged with a lifting lug pressure bar. When the guide vane of the hydro-generator set with the above structure is assembled and hoisted, the guide vane body is fixed by tightening the nut on the threaded rod. The role of the lock. Compared with the prior art, the utility model has the advantages of simple structure, convenient use, high assembly efficiency, and can reduce production costs, and effectively prevents the guide vanes from falling during the hoisting process, eliminating potential safety hazards. One end of the lifting lug pressure rod is provided with a lifting hole, and the other end is a curved surface structure, which is in contact with the guide vane body, which can prevent the lifting lug pressure rod from scratching the guide vane body.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are exemplified, and detailed descriptions are as follows in conjunction with the accompanying drawings: Please refer to Figure 1 and Figure 2, a kind of hydraulic generator set guide vane assembly and hoisting tooling, Including a screw rod 1, one end of the screw rod 1 is a hook 1-1, the other end of the screw rod 1 is a threaded rod 1-2, a nut 5 is installed on the threaded rod 1-2, and the screw rod 1 is connected with the clamp body 2 , the clamp body 2 includes a tie rod connecting part 2-2 and a lifting lug connecting part 2-1, a hook groove 2-3 is formed between the tie rod connecting part 2-2 and the lifting lug connecting part 2-1, and the tie rod connecting part 2- 2 is provided with a through hole, and the screw rod 1 passes through the through hole, and the drag hook 1-1 of the screw rod 1 and the nut 5 installed on the threaded rod 1-2 are respectively located on both sides of the through hole, so as to realize the connection between the screw rod 1 and the clip. For the specific connection of 2, the lifting lug connecting part 2-1 is hinged with the lifting lug pressure bar 3 through the pin 6, and one end of the lifting lug pressure bar 3 is provided with a lifting hole 3-1, and the other end is an arc structure, which can prevent the lifting lug from being pressed. The rod 3 scratches the guide vane body 4 during hoisting and self-locking.

Working Principle During the use of the tooling described in the utility model, the guide vane body 4 is first placed between the drag hook 1-1 of the screw rod 1 and the hook groove 2-3 of the clamp body 2, and the cutting edge of the guide vane body 4 It is located on the side of the pull hook 1-1. After adjusting the guide vane body 4 to a suitable position, tighten the nut 5 on the threaded rod 1-2 to fix the guide vane body 4 on the tooling. The tooling can be lifted. During the hoisting of the guide vane body 4, the lifting lug pressure rod 3 forms a lever with the pin 6 as the fulcrum, so that self-locking is realized by the self-weight of the guide vane body 4, which effectively prevents the guide vane from being locked during the hoisting process. body 4 falls, in addition, the contact end of lifting lug pressure rod 3 and guide vane body 4 is set as a circular arc surface structure, which can prevent lifting lug pressure rod 3 from scratching guide vane body 4. Compared with the prior art in which wire ropes are used to wind and lift guide vanes, the tooling has the advantages of simple structure, convenient use, high assembly efficiency, and reduced production costs.
