Description

A kind of chain-type valve transmission mechanism

Technical field

The utility model relates to switch cubicle, particularly a kind of chain-type valve transmission mechanism in the switch cubicle.

Background technology

Height piezoelectricity cabinet is as the electric installation control and the protection equipment of power plant, industrial and mining enterprises and transformer station, and the security performance of power distribution cabinet is even more important, therefore; After handcart is return, guarantee that valve mechanism falls fully, cover electrified body fully; At this moment; The cabinet door just can be opened, and valve has covered electrified body fully, just can not have an accident when the operator operates in cabinet.

Traditional electric cabinet valve (see figure 1) is provided with two fan doors (11,12) up and down; Hold a side of door respectively through steel wire rope 13; Through pushing mechanism 14 pulling steel wire ropes 13; Making up and down, two fan valve (11,12) use steel wire rope 13 to open the door and have following defective respectively to both direction unlatching up and down:

1. the valve volume is big, and self is heavy, and the strong point is few, poor stability;

2. adopt the steel wire rope sliding door, valve stressed few, useful life is short;

3. steel wire rope and pushing mechanism have only a fulcrum, and when handcart withdrawed from, valve mechanism blocked sometimes and declines down; High-tension electricity does not cut off, and at this moment, the operator who opens the cabinet door will directly face high-tension electricity; This advances to operate and will get an electric shock, and causes the accident of casualties.

The utility model content

In order to address the above problem, the utility model provides a kind of chain-type valve transmission mechanism, comprises the track that is located on the left side plate, to the doorstep and the Xiamen; To the doorstep and the both sides of Xiamen be respectively equipped with slide block, slide block is stuck in the track, and can slide in orbit; Also comprise cog, lower gear and pull bar, pull bar through chain be set in cog with lower gear on, also comprise collision block and pull bar; One end of pull bar and collision block flexibly connect, and the other end and Xiamen flexibly connect.

Said comprise to the doorstep first to the doorstep with second to the doorstep; First flexibly connects with second to the doorstep to the doorstep, and the Xiamen comprises first Xiamen and second Xiamen, and first Xiamen and second Xiamen flexibly connect; Second end of calling with cog engagement, an end of second Xiamen and lower gear mesh.

Said pull bar is arranged in a crossed manner, pull bar be 8 fonts after chain is connected, go up lower gear during the chain pulling and rotate in the opposite direction.

The two ends up and down of said track are set as arc, and radian is identical.

Said collision block is provided with bayonet socket, and handcart combines with collision block at the bayonet socket place, and the turnover of dolly drives, the advancing or retreat of collision block.

Said pull bar comprises first pull bar and second pull bar, and first pull bar and second pull bar flexibly connect.

The advantage of the chain-type valve transmission mechanism of the utility model is:

1. utilize gear and the chain conduct pulling mechanism of valve up and down, long service life.

2. on collision block, be provided with bayonet socket, make handcart and collision block combine effective.

3. cabinet is provided with track, and valve is connected with track through slide block up and down, and making up and down, valve is that ON/OFF is convenient, can not block along the track slip opening or closing.

4. vision is seen more attractive in appearance internally.

Embodiment

Further specify the utility model with reference to the accompanying drawings.

The utility model provides a kind of chain-type valve transmission mechanism, comprises the track 1 that is located on the left side plate, to the doorstep 2 and Xiamen 3,2 is respectively equipped with slide block 11 with the both sides of Xiamen 3 to the doorstep; Slide block 11 is stuck in the track 1, and can in track 1, slide, also comprise cog 51, lower gear 52 and pull bar 4; The two ends of pull bar 4 respectively through chain 6 be set in cog 51 with lower gear 52 on, also comprise collision block 8 and push rod 7, push rod 7 comprises first push rod 71 and second push rod 72; Saidly to the doorstep 2 comprise that first 21 and second calls 22 to the doorstep; First 21 and second 22 flexibly connects to the doorstep to the doorstep, and Xiamen 3 comprises that first Xiamen 31 and 32, the first Xiamen 31, second Xiamen and second Xiamen 2 flexibly connect; Second 22 an end and 51 engagements that cog, an end of second Xiamen 32 and lower gear 52 engagements to the doorstep.

One end of first push rod 71 is connected with second time valve 32, and the other end is connected with second push rod 72, and an end of second push rod 72 and collision block 8 flexibly connect, and the other end is connected with first push rod 71.

Said pull bar 4 is arranged in a crossed manner, pull bar 4 be after chain 6 is connected 8 fonts be enclosed within cog 51 with lower gear 52 on, cog during chain 6 pullings and lower gear rotates in the opposite direction.
