Description
Technical field
The utility model relates to high-voltage electrical equipment and detects aid, is specifically related to a kind of middle-placed switch cabinet maintenance handcart.
Background technology
Handcart type high voltage switch cabinet also can be withdraw-type switch cabinet or middle, is made up of cabinet, handcart two large divisions.Handcart can be understood like this, be exactly give components and parts as, PT, capacitor, isolation etc. are assemblied on transportable framework, and hand can promote, and is therefore called handcart.Common are isolation handcart, circuit breaker cart, PT handcart (measurable and protection), capacitor handcart, these handcarts can combine by difference requirement again, and such as PT handcart generally all will load onto capacitor protected.These handcarts can be advanced in cabinet by the guide rail in cabinet to realize protection and control action; due to handcart in casing slidably; usually need to arrange buckle or handcart is fixed in cabinet by fixing and locking device; buckle is adopted under prior art; latch, the mechanisms such as block realize spacing fixing in cabinet of handcart, and these fixed forms are firm all not or cause misoperation; and easily corrosion causes stuck phenomenon, makes maintenance be obstructed.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of middle-placed switch cabinet to overhaul handcart.
To achieve these goals, the utility model solves the technical scheme that its technical problem adopts: middle-placed switch cabinet maintenance handcart, comprise handcart frame and be arranged at the roller of handcart frame dual-side, the middle part of the front end face of described handcart frame is provided with handcart frame and fixes latching device, snap close fixed mechanism comprises lock core, two dead bolts, lock core rotates and is arranged in handcart frame front console, two dead bolts respectively line activities are arranged at lock core both sides, two dead bolts are equipped with tooth bar near one end of lock core, lock core is provided with gear, wheel and rack is in transmission connection, and two tooth bars are parallel to each other and are oppositely arranged, wherein, one tooth bar is positioned at the top of gear, another tooth bar is positioned at the below of gear.
It should be noted that further and be provided with reduction torsion spring between described lock core gear and handcart frame, reduction torsion spring makes two dead bolts be in extended configuration all the time, and described lock core is connected by operating grip transmission.
It should be noted that the both sides of the front console of described handcart frame are fixedly connected with push-and-pull bracelet more further, the top of handcart frame is fixedly connected with high-tension distribution equipment installing rack.
The beneficial effects of the utility model: middle-placed switch cabinet maintenance handcart of the present utility model realizes fixing spacing connection by reliable pinion and-rack transmission lock pin mechanism and cabinet, safe and reliable, there will not be misoperation or the stuck situation of corrosion, easily realized the keying of snap close by operating grip.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model.
Embodiment
Middle-placed switch cabinet maintenance handcart as depicted in figs. 1 and 2, comprise handcart frame 1 and be arranged at the roller 2 of handcart frame 1 dual-side, the middle part of the front end face of described handcart frame 1 is provided with handcart frame and fixes latching device, snap close fixed mechanism comprises lock core 3, two dead bolts 4, lock core 3 rotates and is arranged in handcart frame 1 front console, two dead bolts 4 respectively line activities are arranged at lock core 3 both sides, two dead bolts 4 are equipped with tooth bar near one end of lock core 3, lock core 3 is provided with gear, wheel and rack is in transmission connection, and two tooth bars are parallel to each other and are oppositely arranged, wherein, one tooth bar is positioned at the top of gear, another tooth bar is positioned at the below of gear.
Preferably, be provided with reduction torsion spring between described lock core 3 gear and handcart frame 1, reduction torsion spring makes two dead bolts be in extended configuration all the time, and described lock core 3 is connected by operating grip transmission.The both sides of the front console of described handcart frame 1 are fixedly connected with push-and-pull bracelet 5, and the top of handcart frame 1 is fixedly connected with high-tension distribution equipment installing rack 6.
The advantage of handcart type high voltage switch cabinet is, maintenance safety is convenient, can pull out easily and repair, form obvious fracture with switch cubicle during maintenance.Speed can be interrogated when handcart goes wrong in addition and change handcart for subsequent use, so that long interruption duration can not be had influence on.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
