Description
Technical Field
The utility model relates to an interlock in the electrical field.
Background
In the electrical industry, the switch cabinet has a mandatory requirement on the structural design of electrical five-prevention. The electric five-prevention is a general name that five kinds of false touch prevention functions are required to be performed on electric equipment (high-voltage cabinet) in order to ensure personal safety and safety of mechanical equipment, and is one of key measures for electric power safety production. In order to meet the requirement of five prevention, the isolation grounding switch and the cable chamber lower hanging door are interlocked, and the lower hanging door can be opened only when the opening ground is in a position. The traditional method is to adopt a 'soft interlocking' structure, namely a 'brake cable' structure formed by combining hard plastic wires wrapped in an outer plastic hose, wherein the form determines that the material is plastic material due to the structure, and the material also determines the problem of short service life caused by poor weather resistance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a lower hanging door five-prevention interlocking device, the structural style of having avoided "brake cable" completely realizes the interlocking bolt of ground connection branch position.
In order to realize the above-mentioned purpose, the utility model provides a lower hanging door five-prevention interlocking device, including the shunting operating axis, the cover is equipped with the cam on the shunting operating axis, the cam corresponds the setting with the interlocking bolt, the interlocking bolt cooperatees with the reset structure who sets up at horizontal baffle, be provided with down the hanging door under the horizontal baffle, all set up on hanging door and the horizontal baffle down and hold interlocking bolt male jack.
Compared with the prior art, the utility model has the advantages that the shunting operating shaft is rotated to rotate the cam, the convex part of the cam rotates downwards to be contacted with the interlocking bolt and press the interlocking bolt downwards, the interlocking bolt moves downwards and finally passes through the horizontal clapboard and the lower hanging door, and the lower hanging door can not be opened when the cam is in the grounding position; when rotatory shunting operating axis and make the cam upwards rotate to ground connection and close the position, make the interlocking bolt shift up to the normal position again under the effect of reset structure, and then make lower hanging door normally open, keep away the structural style of "brake cable" completely, realize the interlocking bolt of ground connection branch position, the utility model discloses can be used for hanging door under the cubical switchboard five prevent chain.
As a further improvement, the reset structure includes the reset shelf, be provided with reset spring in the reset shelf, reset spring establishes in interlocking bolt periphery, the interlocking bolt is pegged graft in the reset shelf, the reset shelf sets up at the horizontal partition board upper surface, and the interlocking bolt is driven the downstream by the cam like this, and then makes upper end and interlocking bolt connection's reset spring compressed, upwards rotates when the cam, breaks away from with the interlocking bolt, and reset spring no longer receives the decurrent pressure of cam, and then resumes again, drives the upstream with the interlocking bolt, realizes resetting of interlocking bolt.
As the utility model discloses a further improvement, reset spring is the cone form and around establishing in interlocking bolt periphery, and the narrow width down on reset spring can form bigger elasticity after the compression like this for the interlocking bolt can lift up fast and reset.
As a further improvement, the top of interlocking bolt is provided with horizontal pressing plate, horizontal pressing plate's front end is under the cam, horizontal pressing plate's the other end is provided with vertical clamp plate, the arc groove has been seted up on the upper portion of vertical clamp plate, the arc groove is in shunting operating axis one end under, and the cam rotates downwards like this, and with the horizontal pressing plate contact, has increased area of contact, more makes things convenient for the interlocking bolt of pushing down, and after the interlocking bolt resets, the arc groove on the vertical clamp plate contacts with the end of shunting operating axis for the interlocking bolt can not rise too high because of elasticity.
Drawings
Fig. 1 is a schematic view of the internal structure of the present invention.
Fig. 2 is a schematic view of the interlocking structure of the present invention.
The device comprises a cam 1, an arc groove 2, a tapping operation shaft 3, a vertical pressing plate 4, a horizontal partition plate 5, a reset frame 6, an interlocking bolt 7, a reset spring 8, a horizontal pressing plate 9 and a lower hanging door 10.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the five-prevention interlocking device for the lower hanging door comprises a tapping operation shaft 3, wherein a cam 1 is sleeved on the tapping operation shaft 3, the cam 1 and an interlocking bolt 7 are correspondingly arranged, the interlocking bolt 7 is matched with a reset structure arranged on a horizontal partition plate 5, the lower hanging door 10 is arranged right below the horizontal partition plate 5, and jacks into which the interlocking bolt 7 can be inserted are formed in the lower hanging door 10 and the horizontal partition plate 5; the reset structure comprises a reset frame 6, a reset spring 8 is arranged in the reset frame 6, the reset spring 8 is sleeved on the periphery of an interlocking bolt 7, the interlocking bolt 7 is inserted in the reset frame 6, and the reset frame 6 is arranged on the upper surface of the horizontal partition plate 5; the reset spring 8 is wound on the periphery of the interlocking bolt 7 in a cone shape; the top of interlocking bolt 7 is provided with horizontal press plate 9, the front end of horizontal press plate 9 is under cam 1, the other end of horizontal press plate 9 is provided with vertical clamp plate 4, arc groove 2 has been seted up on the upper portion of vertical clamp plate 4, arc groove 2 is under 3 one ends of shunting operating axis.
When the device works, the cam 1 and the tapping operation shaft 3 are welded together, the tapping operation shaft 3 is in a hexagonal shape and can be rotated by a wrench, after the tapping operation shaft 3 rotates to drive the convex part of the cam 1 to rotate downwards, the cam 1 presses the horizontal pressing plate 9 downwards, so that the horizontal pressing plate 9 moves downwards, the interlocking bolt 7 connected with the horizontal pressing plate is driven to move downwards to penetrate through the horizontal partition plate 5 and the upper surface of the lower door, and the aim that the lower hanging door 10 cannot be opened when the tapping operation shaft 3 rotates to the grounding position is fulfilled; after the convex part that the operation shaft 3 of shunting rotated and drove cam 1 upwards rotates, cam 1 and horizontal pressing plate 9 separation, reset spring 8 has lost the decurrent pressure of cam 1 this moment, reset under the effect of self elasticity, and then drive interlocking bolt 7 and shift up, when the arc groove 2 of vertical clamp plate 4 pushed up the operation shaft 3 end of shunting, stop shifting up, interlocking bolt 7 contracts to return in the frame 6, when shunting operation shaft 3 rotated to ground connection closed position like this, lower overhead door 10 can be opened.
The utility model completely avoids the structural form of a brake cable, the rotation of the tapping operation shaft 3 is used for driving the cam 1 which is welded with the shaft into a whole, the cam 1 presses down (the grounding tapping) interlocking bolt 7, and the lower hanging door 10 can not be opened; the cam 1 rotates (the grounding closing position) and the reset pressure spring lifts the interlocking bolt 7, the lower hanging door 10 can be normally opened, the requirement of five-prevention can be well met, and the interlocking of the isolation grounding switch and the cable chamber lower door is realized.
