Abstract

The utility model discloses a handcart operation interlocking mechanism of a middle-and-high voltage switch cabinet. The handcard operation interlocking mechanism of the middle-and-high voltage switch cabinet comprises a handcart frame and a handcart panel. A lead screw mechanism is arranged between the handcart frame and the handcart panel. The handcart panel can lock a cabinet door of the switch cabinet through a locking mechanism. The front end of the handcart frame is provided with an ejecting rod. The inside part of the cabinet door is provided with a sliding block which is provided with a guiding inclined surface that opposes the ejecting rod. The inside part of the handcart panel is provided with a spacing surface. The ejecting rod can abut against the guiding inclined surface of the sliding block and makes the sliding block be disengaged from the spacing surface of the handcart panel. The ejecting rod can separate from the guiding inclined surface of the sliding block and makes the sliding block block the spacing surface at inside part of the handcart panel. After the structure of the handcart operation interlocking mechanism is adopted, the handcart operation interlocking mechanism has advantages of: simple structure, convenient and labor-saving operation, high reliability and no maloperation. The handcart operation interlocking mechanism of the middle-and-high voltage switch cabinet further has functions of: ensuring high operation safety; realizing convenient mounting and maintenance; obtaining large force bearing, accurate action, flexible operation and labor saving in forward movement of the handcart; simultaneously reducing production cost; and improving economic benefit.

Description

Middle-high voltage switch handcart operation interlocking mechanism

Technical field

The utility model relates to a kind of handcart operation interlocking mechanism, specifically a kind of middle-high voltage switch handcart operation interlocking mechanism.

Background technology

In the design of operation interlocking mechanism arrangement, there are a lot of potential safety hazards in the manufacturer of existing domestic mesohigh and direct-current switch cabinet, such as separate between interlock, there is not necessary contact, so cause its operating sequence also there is no inevitable contact, the randomness of user's operation is larger, once misoperation, is prone to accidents; Meanwhile, domestic a lot of mesohighs and direct-current switch cabinet operation interlocking mechanism more complicated, production cost is higher, operation effort, reliability is not high, and installation and maintenance inconvenience causes user easily to slip up in the time of operation operation.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to operate, and reliability is high, middle-high voltage switch handcart operation interlocking mechanism convenient for installation and maintenance.

In order to solve the problems of the technologies described above, middle-high voltage switch handcart operation interlocking of the present utility model mechanism, comprise handcart vehicle frame and handcart panel, between handcart vehicle frame and handcart panel, there is the screw body that can make handcart vehicle frame move between test position and service position, handcart panel can lock by the cabinet door of locking mechanism and switch cubicle, the front end of handcart vehicle frame is provided with push rod, cabinet door inner side is provided with slide block that can in the vertical direction lower slider, on slide block, be provided with the guiding surface relative with push rod, handcart panel inner side has confined planes, push rod can be pressed against on the guiding surface of slide block and make slide block depart from the confined planes of handcart panel, push rod also can leave the guiding surface of slide block and make slide block gear on the confined planes of handcart panel inner side.

The both sides of described handcart panel are provided with telescopic dead bolt, are also provided with the latch that stretches out handcart panel end face in handcart panel, and described latch can be controlled dead bolt and move handcart panel locking.

Adopt after above-mentioned structure, due to the push rod of front end setting and the slide block of cabinet door inner side installation of handcart vehicle frame, thus when handcart vehicle frame is during in test position, thereby push rod is pressed against on the guiding surface of slide block and the confined planes that makes slide block depart from handcart panel can be opened handcart panel, when handcart vehicle frame is in work, thereby push rod leaves the guiding surface of slide block and make slide block gear on the confined planes of handcart panel inner side, handcart panel can not be opened, its structure arranges simply, easy to operate, reliability is high, can there is not the problem of misoperation, ensure the fail safe of operation, installation and maintenance are also very convenient, when handcart advances, load-bearing is large, action accurately, flexible operation Portable power saving, reduced manufacturing cost simultaneously, improve economic benefit.

Embodiment

Below in conjunction with the drawings and specific embodiments, middle-high voltage switch handcart operation interlocking of the present utility model mechanism is described in further detail.

As shown in the figure, middle-high voltage switch handcart operation interlocking of the present utility model mechanism, comprise handcart vehicle frame 1 and handcart panel 2, between handcart vehicle frame 1 and handcart panel 2, there is the screw body 3 that can make handcart vehicle frame move between test position and service position, promoting screw body by handle can make handcart vehicle frame move back and forth between test position and service position, handcart panel 2 can lock by the cabinet door of locking mechanism and switch cubicle, the front end of handcart vehicle frame 1 is provided with push rod 5, cabinet door inner side is provided with slide block 4 that can in the vertical direction lower slider, slide block 4 slides up and down by track, on slide block 4, be provided with the guiding surface relative with push rod 5, handcart panel 2 inner sides have confined planes, when handcart vehicle frame is during in test position, push rod 5 is pressed against on the guiding surface of slide block 4 and makes slide block 4 depart from the confined planes of handcart panel 2, when handcart vehicle frame is in work, push rod 5 leaves the guiding surface of slide block 4 and slide block 4 is kept off on the confined planes of handcart panel 2 inner sides.

Further can be provided with telescopic dead bolt 6 in the both sides of handcart panel 2, also be provided with the latch 7 that stretches out handcart panel end face in handcart panel 2, latch 7 can be controlled dead bolt 6 and move handcart panel 2 is locked.

Its operation principle is as follows:

As shown in Figure 1, swinging handle, moves from service position handcart to test position, now slide block 4 is due to the support of push rod 5, freely along moving on track, in the time that handcart arrives test position, slide block no longer blocks handcart panel 2 inner side limiting-position faces, and so far, on cabinet, handcart panel can be opened from outward;

As shown in Figure 2, swinging handle, makes handcart move to service position from test position, and now slide block, owing to losing the support of push rod 5, freely glides along track, blocks on the confined planes of handcart panel 2 inner sides, and so far, on cabinet, handcart panel cannot be opened.
