Abstract
The utility model discloses a large-scale cylinder pin dismounting device of hydroelectric generating set, hollow stainless steel cylinder (4) on be provided with middle part backup pad flange (3), hollow stainless steel cylinder (4) inside be provided with lower part flange (6), the both sides of lower part flange (6) be provided with bottom connecting screw (7), bottom connecting screw (7) be connected with cylinder pin (8) that the below set up, middle part backup pad flange (3) top be provided with hydraulic jack (2), the top of hydraulic jack (2) be provided with top flange (1); the hand chain block overcomes the defects that the hand chain block using 3T in the prior art is not very inconvenient to operate in a limited space and has safety problems, and has the advantage of ensuring the safety of disassembly under the condition of limited space.
Description
Technical Field
The utility model relates to the engineering machine tool field, more specifically a large-scale barrel pin dismounting device of hydroelectric set.
Background
Current dismantlement technique is for using to erect two calabashes and promote the extraction to the barrel pin, because barrel pin diameter is big, normal behavior is for generating set provides the rotation torque, this unit capacity just reaches 350MW, belong to large-scale unit, the in-process of dismantlement is extremely difficult, and use original single to erect calabash technique just can not be for certain special barrel pin, and use 3T's chain block to operate in the finite space also very inconvenient, the fulcrum of establishing is hung to the calabash simultaneously is also not good to be searched, the condition of drawing to one side probably appears, the security problem is also not optimistic.
Disclosure of Invention
The utility model aims to overcome the weak point of above-mentioned background art, and provide a large-scale barrel round pin dismounting device of hydroelectric set.
The utility model aims at being implemented through the following technical scheme: a large cylinder pin dismounting device for a hydroelectric generating set comprises a top flange, a hydraulic jack, a middle supporting plate flange, a hollow stainless steel cylinder, a connecting screw rod, a lower flange and a bottom connecting screw rod;
the hollow stainless steel cylinder on be provided with middle part backup pad flange, hollow stainless steel cylinder inside be provided with the lower part flange, the both sides of lower part flange be provided with bottom connecting screw, the section of thick bamboo pin junction that sets up with the below of bottom connecting screw, middle part backup pad flange top be provided with hydraulic jack, hydraulic jack's top be provided with the top flange, connecting screw pass in proper order be located the top flange that the top set up with middle part backup pad flange to it is fixed with the lower part flange that the below set up.
The utility model has the advantages of as follows: 1. the utility model discloses special use is in hydroelectric set hydraulic generator rotor and main shaft connecting cylinder round pin dismantlement frock, its simple manufacture, and is practical, adopts the block structure, and single spare part quality is light, and intensity is big, can make things convenient for putting and carrying of frock, is fit for it and is used for narrow and small restricted space, uses and can avoid the calabash to draw safety problem to one side, extracts the cylinder round pin with the help of the disposable that this device can relax, and can not produce the damage to the surface of cylinder round pin, has guaranteed the safety of cylinder round pin equipment.
Drawings
Fig. 1 is a schematic view of the structure using structure of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
In the figure: the hydraulic lifting jack comprises a top flange 1, a hydraulic jack 2, a middle supporting plate flange 3, a hollow stainless steel cylinder 4, a connecting screw rod 5, a lower flange 6, a bottom connecting screw rod 7 and a cylinder pin 8.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, which are not intended to limit the present invention, but are merely exemplary; while the advantages of the invention will be apparent and readily appreciated by the description.
Referring to FIGS. 1-2: a large cylinder pin dismounting device for a hydroelectric generating set comprises a top flange 1, a hydraulic jack 2, a middle support plate flange 3, a hollow stainless steel cylinder 4, a connecting screw rod 5, a lower flange 6 and a bottom connecting screw rod 7;
hollow stainless steel section of thick bamboo 4 on be provided with middle part backup pad flange 3, hollow stainless steel section of thick bamboo 4 inside be provided with lower part flange 6, the both sides of lower part flange 6 be provided with bottom connecting screw 7, bottom connecting screw 7 be connected with the section of thick bamboo round pin 8 that the below set up, 3 tops of middle part backup pad flange be provided with hydraulic jack 2, hydraulic jack 2 top be provided with top flange 1, connecting screw 5 pass in proper order be located the top set up top flange 1 with middle part backup pad flange 3 to it is fixed with the lower part flange 6 that the below set up.
The utility model discloses a concrete use as follows: when the cylinder pin 8 is disassembled, firstly, the connecting screw rod 5 penetrates through the lower flange 6, then the bottom connecting screw rod 7 is connected with the cylinder pin 8, then the hollow stainless steel cylinder 4 is installed for supporting, the middle support plate flange 3 penetrates through the connecting screw rod 5 to be matched and connected with the hollow stainless steel cylinder 4, then the hydraulic jack 2 is placed on the middle support plate flange 3, and then the top flange 1 is installed. After the installation is finished, the hydraulic jack 2 is operated, and the cylinder pin 8 is easily pulled out. By means of the auxiliary tool, the cylinder pin can be directly pulled out, and the disassembly safety can be guaranteed under the condition that the space is limited.
The above-mentioned parts not described in detail are prior art.
