Description
Technical Field
The utility model belongs to the hydroelectric generating set field of overhauing. Namely a special tool for installing the flange connecting bolt of the main shaft of the water turbine.
Background
In the prior art, 4 hydroelectric generating sets in a power plant are in a vertical shaft suspension type. The flange on the main shaft has 20 connecting bolts (M110 multiplied by 650), the weight of each connecting bolt is 50kg, the diameter of the flange is 1600mm, the thickness is 500mm, the length of the bolt pin part is 200mm, and the bolt pin part is a pin bolt, so the matching is tight, the installation is difficult, the labor intensity of workers is high, the danger is high, and the installation time is long. In the past, a traditional mounting process of bolts and pins of a main shaft flange is adopted, a simple wooden working platform is erected below the flange, and supporting points and stress points of mounting bolts are arranged on the platform. The disadvantages are that: the platform is built by vaulting pole and plank, and the stress point has elasticity, when 10 tons of jacks erect the dowel bolt on the platform, the platform elasticity back has been overcome to the bolt, and the pin part of bolt just can rebound gradually, just can accomplish the installation of a dowel bolt many times repeatedly, if touch the dowel bolt fit clearance less in addition, when needing great jacking force, the platform can not bear the pressure of jack, causes the platform to transship, can bring danger for work.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the aforesaid not enough and provide a hydraulic turbine main shaft flange connecting bolt installation specialized tool. The problems that the existing bolt is difficult to install, low in efficiency, labor-consuming and the like are solved.
The utility model discloses technical solution is: a special tool for installing a flange connecting bolt of a main shaft of a water turbine is characterized by comprising a hanging frame, wherein the hanging frame comprises a hook arm, a fork plate is transversely welded at the upper part of the hook arm, and a supporting plate is welded at the lower part of the hook arm in the same direction.
The utility model has the advantages that: simple structure, reasonable, convenient operation, manpower saving, high safety, efficiency improvement and maintenance period shortening.
Drawings
Fig. 1 is a structural diagram of the present invention.
Fig. 2 is a schematic view of the usage state of the present invention.
Detailed Description
Referring to fig. 1 and 2, the names of the components are as follows: the hanging rack comprises a hanging rack 1, a fork plate 2, a supporting plate 3, a jack 4, a hook arm 5, a flange 6, a connecting bolt 7 and a fork opening 8.
Referring to fig. 1 and 2, the special tool for mounting the flange connecting bolt of the main shaft of the water turbine comprises a hanger 1, wherein the hanger 1 comprises a hook arm 5, a fork plate 2 (overlapped with a flange 6 and separated from a connecting bolt 7 through a fork opening 8) is transversely welded at the upper part of the hook arm 5, a supporting plate 3 is welded at the lower part of the hook arm 5 in the same direction, and a jack 4 is placed.
In order to improve the working efficiency, reduce the labor intensity of workers and shorten the overhaul period of a unit, technical innovation is carried out on old technology, stress points of all parts are in rigid contact after improvement, a main board of a hanging rack 1 is cut and manufactured by a whole steel plate with the thickness of 15mm, an upper hanging point is formed by two parts, the contact between the hanging point of the main board and a flange is short, and two auxiliary hanging points are designed on two sides of the main board in order to increase the stability. The lower fulcrum is integrated with the main board cutting for increasing the strength, a jack 4 is designed to be placed on a platform of the supporting board 3, the tool is used to achieve the expected effect, and the jack 4 is operated to complete the installation of one pin bolt at one time.
The using method comprises the following steps: as shown in figure 2, the tool is convenient to use and simple to operate. Inserting the bolt into the hole, hanging the tool on the flange 6, placing the jack 4 on the platform of the lower supporting plate 3, operating the jack 4 to extend out to jack the bolt in, and then disassembling.
The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
