Abstract

The synchronous fastening device for the bolt of the variable pitch motor is replaced. When the variable pitch motor is replaced, an original encoder plug of the variable pitch motor and a power supply heavy-load connector need to be pulled out, a screw of the variable pitch motor M12X30 is loosened by using an 18mm fork, after a fixing screw is removed, 4 bolts of a flange face of a gear box rotate reversely and synchronously, the motor is jacked up, but the operation needs the close fit of four persons, the synchronous rotation of the four bolts is guaranteed, otherwise, the variable pitch motor is enabled to be ejected and inclined, and the variable pitch motor is damaged. The utility model discloses the constitution includes: even board (4) and two worker's word boards (2), every the one end of worker's word board all with pivot (10) rotatable coupling, the pivot pass even sliding hole (5) back both ends threaded connection of board have the nut, the both ends of I-shaped board respectively with two ratchet spanner (1) rotatable coupling. The utility model is used for become synchronous fastener of oar motor change bolt.

Description

Synchronous fastening device for replacing bolt of variable pitch motor

Technical Field

The utility model relates to a become synchronous fastener of oar motor change bolt.

Background

When the variable pitch motor is replaced, an original encoder plug of the variable pitch motor and a power supply heavy-load connector need to be pulled out, a screw of the variable pitch motor M12X30 is loosened by using an 18mm fork, after a fixing screw is removed, 4 bolts of a flange face of a gear box rotate reversely and synchronously, the motor is jacked up, but the operation needs the close fit of four persons, the synchronous rotation of the four bolts is guaranteed, otherwise, the variable pitch motor is enabled to be ejected and inclined, and the variable pitch motor is damaged.

Disclosure of Invention

The utility model aims at providing a become synchronous fastener of oar motor change bolt.

The above purpose is realized by the following technical scheme:

the utility model provides a become synchronous fastener of oar motor change bolt, its constitution includes even board and two I-shaped boards, every the one end of I-shaped board all with pivot rotatable coupling, the pivot pass even sliding hole back both ends threaded connection of board have the nut, the both ends of I-shaped board respectively with two ratchet spanner rotatable coupling.

Become synchronous fastener of oar motor change bolt, characterized by: and a handrail which is vertically arranged is fixed on each I-shaped plate.

Has the advantages that:

1. the utility model discloses every ratchet spanner rotates a bolt, operates the device through alone, controls the hand power saw formula action and can realize rotating four bolts simultaneously for become the oar motor by vertical jack-up.

2. The utility model discloses simple structure, convenient operation simultaneously.

Description of the drawings:

fig. 1 is a top view of the present invention;

FIG. 2 is a front view of the present invention;

FIG. 3 is a top view of the present invention in use;

FIG. 4 is a front view of the present invention in use;

in the figure: 1. a ratchet wrench; 2. i-shaped plates; 3. a grab bar; 4. connecting plates; 5. a slide hole; 6. a lower flange face; 7. a variable pitch motor; 8. adjusting the bolt; 9. an upper flange face; 10. a rotating shaft.

The specific implementation mode is as follows:

example 1:

the utility model provides a become synchronous fastener of oar motor change bolt, its constitution includes even board 4 and two I-shaped boards 2, every the one end of I-shaped board all with pivot 10 rotatable coupling, the pivot pass even board 5 back both ends threaded connection have the nut, the both ends of I-shaped board respectively with two ratchet spanner 1 rotatable coupling.

Example 2:

according to the synchronous bolt fastening device for changing the pitch motor in embodiment 1, a handrail rod 3 which is vertically arranged is fixed on each I-shaped plate and is fixedly welded.

The working principle is as follows: have four screw holes on the flange face 6 of lower part, with four bolt difference threaded connection in every screw hole for the highly uniform of every bolt, then all overlap every ratchet spanner of device on adjusting bolt 8, both hands hold the handrail respectively, carry out the dragsaw formula reciprocating motion, can realize like this that four bolts rotate in step, make four bolts can push up simultaneously and jack-up become oar motor 7 on upper portion flange face 9.

Claims

1. The utility model provides a become synchronous fastener of oar motor change bolt which characterized by: the structure comprises a connecting plate and two I-shaped plates, wherein one end of each I-shaped plate is rotatably connected with a rotating shaft, the rotating shaft penetrates through a sliding hole of the connecting plate, nuts are connected to the two ends of each sliding hole in a threaded mode, and the two ends of each I-shaped plate are rotatably connected with two ratchet wrenches respectively.

2. The synchronous bolt fastening device for the change of the pitch motor according to claim 1, which is characterized in that: and a handrail which is vertically arranged is fixed on each I-shaped plate.
