Abstract
The utility model is provided with symmetrical left and right supports which are arranged under the front of a handcart bedplate of a light voltage switch cabinet. The bottoms of the supports overlap with each other and are fixed by screws, while the tops are fixed below the handcart bedplate, with a rotary shaft extending through the two supports. Both ends of the rotary shafts are fixed to the frames by screws and the shafts are mounted with two locking parts, with the two locking parts overlapping with each other. The locking parts are positioned at the middle of the rotary shaft with the locking parts rotary at a 90 degree on the rotary shaft. A rotary screw and two pin shafts mounted with a reset spring are arranged below the handcart bedplate to fix the trigger plate under the handcart bedplate and to make the first of the two locking parts extend through the waist hole in the trigger plate and the aperture in the handcart bedplate and protrude out of the handcart bedplate. As the handcart is pushed in, the trigger plate pushes the protruded locking parts to a horizontal position. The handcart can be pushed in and the outward movement of the handcart is stopped by the locking parts, thereby the handcart is incapable of falling off to the ground and the safety is secured.
Description
Technical field
The utility model is the anti-handcart of the high-tension switch cabinet mechanical interlocks that comes off when shifting out, relate to and remove circuit breaker cart in the middle high-tension switch cabinet, PT handcart, isolate handcart etc. and be connected with switch cabinet body when unreliable not having the dolly of transfer or shift dolly, prevent to be shed to when handcart from shifting out the mechanical interlocks on ground reliably.
Background technology
Remove circuit breaker cart in the middle high-tension switch cabinet, PT handcart, isolate handcart etc., in high-tension switch cabinet, track is pulled out in its propelling all has certain altitude apart from ground, when needs debugging, inspection, maintenance, replacing, need handcart is moved on the transfer dolly, therefore, shift the degree of reliability that is connected between dolly and switch cabinet body and just determined the safe coefficient that handcart shifts out.There is not the machinery interlocking between present domestic transfer dolly and switch cabinet body, whether it connects reliably between the two, or do not connect, all can not limit handcart moves outside cabinet, but operate by operational procedure and guarantee by operating personnel's strictness, this just exists handcart in the hidden danger that comes off easily when mobile outside cabinet, causes the damage owing to handcart to bring unnecessary loss, particularly the circuit breaker cart cost is very high, and its loss is also huge.And the anti-handcart of the custom-designed high-tension switch cabinet mechanical interlocks that comes off when shifting out has remedied just between transfer dolly and switch cabinet body and has been connected unreliable or connectionless defective.
Summary of the invention
The anti-handcart of the utility model high-tension switch cabinet mechanical interlocks that comes off when shifting out, be left socle and the right support that two symmetries are installed in high-tension switch cabinet handcart platen front lower place, frame bottom is overlapping and tighten up with screw, the top is fixed on handcart platen bottom, run through a rotating shaft between the two stands, the rotating shaft two ends are screwed on support, be with two locking pieces in the rotating shaft, two locking pieces overlap, locking piece is positioned in the middle of the rotating shaft by axle sleeve, and can in rotating shaft, make 90 degree and rotate, following at the handcart platen in addition with rotatable screw and two bearing pins that are with back-moving spring, the fixing swinging plate of handcart platen bottom, and make a locking piece in two locking pieces pass waist hole on the swinging plate and the perforate on the handcart platen, reach above the ride plate.
The locking piece head that reaches above the ride plate is made oblique arrowhead form, and there is a straight pin its underpart, and this straight pin inserts the hole below another locking piece, and two locking pieces are coincided together.
Advantage is effectively to prevent to be shed to when handcart from shifting out ground, thereby protects the safety of levying the high pressure circuit breaker.

Embodiment
See also accompanying drawing 1, shown in 2, the left socle 5 and the right support 6 of two symmetries are installed in high-tension switch cabinet handcart platen 12 front lower places, support 5,6 bottoms are overlapping and tighten up with screw 10, the top is fixed on handcart platen 12 bottoms by screw 13, two stands 5, run through a rotating shaft 4 between 6, rotating shaft 4 two ends are fixed on support 5 with screw 14, on 6, be with two locking pieces 1 in the rotating shaft 4,2, two locking pieces 1,2 overlap, be positioned at rotating shaft 4 centres by axle sleeve, and can in rotating shaft 4, make 90 degree and rotate, following at handcart platen 12 in addition with rotatable screw 11 and two bearing pins 8 that are with back-moving spring 15, the fixing swinging plate 7 of handcart platen 12 bottoms, and make locking piece 1 pass waist hole 16 on the swinging plate 7 and the perforate on the handcart platen 12, reach above the ride plate 12.
Reach locking piece 1 head above the ride plate 12 is made oblique arrowhead form, and there is a straight pin 9 its underpart, and this straight pin 9 inserts the hole 17 below locking pieces 2, makes two
When handcart need push in the cabinet, the transfer dolly that is loaded with handcart is aimed at high-tension switch cabinet, the position fixing handle on the dolly is shifted in actuating, position fixing handle promptly promotes swinging plate simultaneously in operating process, swinging plate promotes locking piece 1, making it be rotated down 90 ° is horizontal, handcart can push test position in the cabinet, withdraw the transfer dolly this moment, position fixing handle on it is also withdrawn thereupon, and the back-moving spring that swinging plate is mounted on the bearing pin that resets is got back to the home position, and the locking piece 1 that loses swinging plate thrust automatically resets by deadweight and eccentric locking piece 2, i.e. half-twist upward just stretches in the handcart chassis in the custom-designed for this purpose open slot; If handcart is outside when mobile, locking piece 1 stopped by left and right support base, thereby guaranteed not to be connected with switch cabinet body when unreliable having the dolly of transfer or shift dolly, and handcart is shifted out outside the cabinet, reaches to prevent that handcart is shed to the purpose on ground.
Claims (2)
