Abstract

The utility model discloses a limit unit of a handcart of a switch cabinet. A locking plate, a curved plate and a cantilever support of the limit unit are fixed on a middle cabinet body partition plate; a limit disc is fixed on the locking plate; after passing through the limit disc and a limit hole on the curved plate, an operating rod is firmly connected with a crankarm; a pressure spring and a limit sleeve are sleeved on the operating rod; small lateral plates are movably connected with the bottom of the cantilever support; link lever joints are fixed on both ends of a pull rod and respectively movably connected with the respective small lateral plates; the middle part of the pull rod is clamped in a slide way of the crankarm; and the small lateral plates can push a limit lever to pass through the middle cabinet body partition plate. By limiting the handcart, the limit unit has a good prevention effect in the prevention of the arc discharge accident on contacts caused by the retreat of the handcart and the earthquake resistance of switch equipment, and is characterized by high processing precision and accurate positioning.

Description

A kind of switch cabinet handcart stopping means
Technical field
The utility model relates to a kind of switch cabinet handcart stopping means.
Background technology
Mainly there is following problem in present domestic existing product: handcart is realized pushing and withdrawing from by the operation worm and gear in the switch cubicle, handcart is located by leading screw after arriving the service position, do not prevent the stopping means that handcart retreats, because of vibrations handcart is retreated easily or the handcart operation dynamic/static contact arcing accident that causes not in place.Nuclear level switchgear assembly requires still can carry out its safety function under the seismic environment condition, and original structural design pattern can not satisfy the designing requirement of antidetonation.
Summary of the invention
For solving the problem of above existence, the utility model provides a kind of switch cabinet handcart stopping means, and its technical scheme of taking is:
The lockplate of this stopping means, bent plate and cantilever seat are fixed on the cabinet median septum, position-arresting disk is fixed on the lockplate, position-arresting disk can limit the rotational angle of action bars, action bars is fixedlyed connected with connecting lever after passing spacing hole on position-arresting disk and the bent plate, this spacing hole is the regular hexagon hole, can limit the rotation of action bars, action bars is the regular hexagon axle with regular hexagon hole tabling, action bars near the spacing hole rear end partly is a circular shaft, be with stage clip and stop collar on the action bars, stop collar can limit the position of action bars, and the rear end of action bars is fixed with spacing pressing plate, and stage clip is connected between spacing pressing plate and the bent plate, stop collar is connected between bent plate and the connecting lever, the bottom of cantilever seat flexibly connects little side plate, and the two ends of pull bar are fixed with linkage connector, and they flexibly connect each self-corresponding little side plate respectively, the mid portion of pull bar is stuck on the chute of connecting lever, gag lever post is positioned near the cantilever seat, and when little side plate upwards rotated, little side plate can head on gag lever post and pass the cabinet median septum.
This device is spacing by handcart, causes the antiseismic effect of contact arcing accident, switchgear to play the excellent prevention effect for preventing that handcart from giving up the throne, and has the machining accuracy height, the characteristics of accurate positioning.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2, lockplate 1, bent plate 4 and cantilever seat 14 are fixed on the cabinet median septum 16, position-arresting disk 2 is fixed on the lockplate 1, action bars 3 is fixedlyed connected with connecting lever 9 after passing spacing hole on position-arresting disk 2 and the bent plate 4, this spacing hole is the regular hexagon hole, action bars 3 is the regular hexagon axle with regular hexagon hole tabling, action bars 3 parts near the spacing hole rear end are circular shaft, be with stage clip 7 and stop collar 5 on the action bars 3, the rear end of action bars 3 is fixed with spacing pressing plate 8, stage clip 7 is connected between spacing pressing plate 8 and the bent plate 4, stop collar 5 is connected between bent plate 4 and the connecting lever 9, the bottom of cantilever seat 14 flexibly connects little side plate 13, the two ends of pull bar 10 are fixed with linkage connector 11, and they flexibly connect each self-corresponding little side plate 13 respectively, and the mid portion of pull bar 10 is stuck on the chute 6 of connecting lever 9, gag lever post 15 is positioned near the cantilever seat 14, and gag lever post 15 can pass cabinet median septum 16 and move up and down.
After the service position is operated on the handcart chassis, pull out action bars 3, stage clip 7 is compressed, action bars 3 turns clockwise, the part of action bars 3 this moment in spacing hole is circular shaft, can not be limited to rotate, connecting lever 9 upwards rotates under the effect of action bars 3, drive pull bar 10 transverse movements under the restriction of the chute 6 of connecting lever 9, pull bar 10 promotes little side plate 13 and rotates up around cantilever seat 14, moves upward thereby promote gag lever post 15, position-arresting disk 2 is spacing behind action bars 3 rotations 60 degree, operation puts in place, and action bars 3 resets under the active force of stage clip 7 and be locked, the also limited locking in handcart chassis.Be rotated counterclockwise 60 degree after action bars 3 pulled out and remove limitation locking.
