Abstract

Power plant's special ring flange dismouting spanner booster. Various pipelines in the power plant are erected, the operable space is narrow, the size of the traditional stressing and hydraulic wrench is huge, and the requirement of pipeline maintenance in the power plant cannot be completely met. The utility model discloses a constitution includes: the upper shell body (7) and the lower shell body (8), a large gear shaft (1), an intermediate shaft gear (2) and a small gear shaft (3) are arranged in the upper shell body and the lower shell body, the large gear shaft is meshed with the intermediate shaft gear, the intermediate shaft gear is meshed with the small gear shaft, the large gear shaft, the intermediate shaft gear and the small gear shaft are respectively connected with the upper shell body and the lower shell body through a group of shaft sleeves (4), the upper shell body and the lower shell body are connected through a group of bolts (9), and a handle is connected with the upper shell body and the lower shell body through 2 pins (10). The utility model is suitable for a special ring flange dismouting spanner booster of power plant.

Description

Special flange plate dismounting wrench assistor for power plant

The technical field is as follows:

the utility model relates to a special ring flange dismouting spanner booster of power plant

Background art:

various pipelines in the power plant stand upright, the operable space is narrow and small, the disassembly and the installation are not convenient, and the traditional force application wrench or the hydraulic wrench and the like cannot completely meet the requirement of pipeline maintenance in the power plant due to huge volume.

The utility model has the following contents:

the utility model aims at providing a special ring flange dismouting spanner booster of power plant

The above purpose is realized by the following technical scheme:

the utility model provides a special ring flange dismouting spanner booster of power plant, its constitution includes: the upper shell and the lower shell are internally provided with a large gear shaft, a middle shaft gear and a pinion shaft, the large gear shaft is meshed with the middle shaft gear, the middle shaft gear is meshed with the pinion shaft, the large gear shaft, the middle shaft gear and the pinion shaft are respectively connected with the upper shell and the lower shell through a group of shaft sleeves, the upper shell and the lower shell are connected through a group of bolts, and a handle is connected with the upper shell and the lower shell through 2 pins.

Power plant's special ring flange dismouting spanner booster, the pinion shaft hexagonal axial through-hole has respectively, pinion shaft tooth number be less than the pinion shaft, the hexagonal hole in the pinion shaft in be equipped with box spanner, the hexagonal hole in the pinion shaft in insert hexagon socket spanner.

The utility model has the advantages that:

1. the utility model is composed of a group of gears meshed with each other, the number of teeth of a pinion shaft (Z2) is less than that of a pinion shaft (Z1), so that the output torque can be effectively enhanced according to the proportion of Z1/Z2.

2. The utility model discloses a structure has the detachable handle, therefore can be equipped with the handle of multiple angle in order to adapt to different workspace's maintenance operation, has solved the partial unsuitable limitation such as hydraulic pressure spanner, air wrench or general spanner, because the utility model discloses a afterburning part is solitary device, and shared space is very little, can satisfy almost the maintenance work demand of the majority in the power plant.

3. The utility model discloses simple structure, convenient to use is owing to use odd number gear to carry out the transmission moreover, and the direction of operation is unanimous with the bolt direction of rotation who dismouting, can be indirect avoid the maloperation, and then has improved work efficiency.

4. The utility model discloses a manual operation can not produce the personal safety accident that mechanical power tool causes, is favorable to the safety control of enterprise.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a sectional view a-a of fig. 1.

The specific implementation mode is as follows:

example 1:

the utility model provides a special ring flange dismouting spanner booster of power plant, its constitution includes: the upper shell and the lower shell are internally provided with a large gear shaft 1, an intermediate shaft gear 2 and a small gear shaft 3, the large gear shaft is meshed with the intermediate shaft gear, the intermediate shaft gear is meshed with the small gear shaft, the large gear shaft, the intermediate shaft gear and the small gear shaft are respectively connected with the upper shell and the lower shell through a group of shaft sleeves, the upper shell and the lower shell are connected through a group of bolts, and a handle is connected with the upper shell and the lower shell through 2 pins.

Example 2
