Description
Technical Field
The utility model relates to a modular mechanism handcart interlocking piece belongs to the interlocking device technical field of circuit breaker.
Background
The handcart type circuit breaker interlocking mechanism is a device which is used for limiting the switching-on and switching-off of a circuit breaker of a high/low voltage switch cabinet synchronously with the pushing and withdrawing of a handcart during test, maintenance and power transmission and can be divided into an electrical interlocking mechanism and a mechanical interlocking mechanism. The electric interlocking mechanism is easy to realize, flexible and simple, and the two interlocked devices can be installed at different positions but have poor reliability; the mechanical interlocking mechanism has higher reliability than the electrical interlocking mechanism, but has a more complex structure. The components of the existing mechanical interlocking mechanism of the handcart type circuit breaker are generally arranged on the handcart through respective racks. The interlocking mechanism has a plurality of parts, and the parts are complex to process, assemble and overhaul; the transmission parts are multiple, the clamping stagnation phenomenon is easy to occur in the use process, the interlocking is not reliable, and potential safety hazards are brought to the operation of a power grid.
Disclosure of Invention
Technical problem to be solved
In order to solve the problem, the utility model provides an adopt high integrated configuration design's modular mechanism handcart interlocking piece, the while action reliability is high, and processing technology is single and efficient, low in production cost.
(II) technical scheme
The utility model discloses a modular mechanism handcart interlocking, including the interlocking main part, interlocking main part top one side be equipped with energy storage holding catch restriction face, energy storage holding catch restriction face have to prevent the swing inclined plane, the interlocking main part on open and to have the displacement slotted hole, one of them displacement slotted hole outside is equipped with prevents the swing facade, the interlocking main part form the extension board through bending, should extend the board and be located interlocking main part below, and it has handcart shutting restriction hole to open on this extension board, handcart shutting restriction hole downside be equipped with handcart interlocking board working face, interlocking main part one side be equipped with self extension spring couple that resets, this self extension spring couple upside that resets is equipped with combined floodgate turning arm under the working face.
Furthermore, the anti-swing inclined plane and the anti-swing vertical plane are provided with angles, so that the effects of stabilization and limitation are achieved, and the interlocking part main body can be unlocked under the effect of the self-reset tension spring.
Furthermore, the limiting surface of the energy storage retaining latch is matched with the energy storage retaining latch to realize mutual restriction.
Furthermore, a linkage assembly capable of moving the interlocking part main body is arranged in the displacement slotted hole, so that the interlocking part main body can conveniently move to be opened and closed.
(III) advantageous effects
Compared with the prior art, the utility model, it has following beneficial effect: the utility model discloses a highly integrated structural design, the action reliability is high, and processing technology is single and efficient, low in production cost.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is the structure schematic diagram of the utility model discloses a modular mechanism handcart interlocking piece.
Fig. 2 is a schematic side structure diagram of the handcart interlocking part of the modular mechanism of the present invention.
Fig. 3 is a top view of a modular mechanism handcart interlocking member of the present invention.
1. The device comprises an energy storage retaining pawl limiting surface, 2, an anti-swing inclined surface, 3, a displacement hole groove, 4, an anti-swing vertical surface, 5, a closing crank arm pressing action surface, 6, a self-reset tension spring hook, 7, a handcart locking limiting hole and 8, and a handcart interlocking plate action surface.
Detailed Description
The handcart interlocking part comprises an interlocking part main body, wherein an energy storage retaining pawl limiting surface 1 is arranged on one side of the interlocking part main body, the energy storage retaining pawl limiting surface 1 corresponds to a swing preventing inclined plane 2, a displacement slotted hole 3 is formed in the interlocking part main body, a swing preventing vertical face 4 is arranged on the outer side of one displacement slotted hole 3, the interlocking part main body forms an extension plate through bending, the extension plate is located below the interlocking part main body, a handcart locking limiting hole 7 is formed in the extension plate, a handcart interlocking plate acting face 8 is arranged on the lower side of the handcart locking limiting hole 7, a self-reset tension spring hook 6 is arranged on one side of the interlocking part main body, and a closing crank arm pressing acting face 5 is arranged on the upper side of the self-reset tension spring hook 6.
When the switch is in a closing state, the interlocking piece main body cannot be lifted upwards under the limitation of the closing crank arm. Therefore, the switch cannot be moved out or pushed to a working position in a switching-on state, and the function of preventing the handcart from being moved when the switch is switched on is achieved.
When the switch is in a switching-off state to push the handcart to move, the interlocking plate of the handcart is lifted upwards, the interlocking piece main body is lifted upwards while the interlocking piece main body is lifted upwards, and the energy storage retaining latch limiting surface 1 of the handcart and the lug boss of the energy storage retaining latch are restricted mutually after the interlocking piece main body is lifted to the highest point, so that the retaining latch cannot act under the action of external force. Thereby preventing the switch from being switched on by mistake in the moving process of the handcart.
Wherein, the anti-swing inclined plane 2 and the anti-swing vertical plane 4 are provided with angles.
The said energy storage retaining latch limiting surface 1 matches the energy storage retaining latch.
And a linkage assembly for moving the interlocking piece main body is arranged in the displacement slotted hole 3.
The utility model discloses a highly integrated structural design, the action reliability is high, and processing technology is single and efficient, low in production cost.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
