Description
Technical field
The present invention relates to a kind of switch cubicle, and in particular to a kind of switch cabinet handcart propulsion plant.
Background technology
In middle pressure (12-40.5Kv) power supply-distribution system, breaker and all kinds of electric appliance units are widely used.For convenience of maintenance
The reliability powered with raising, and usually console mode hand is installed on a chassis or made to breaker and all kinds of electric appliance units
Car, become packaged type part.On the premise of in accordance with for distribution requirement, these movable parts can be in power distribution cabinet
It is into and out.The movable part of chassis vehicle type all carries propulsion and (exits) mechanism at present, and they match somebody with somebody with the guide rail in cabinet
Close, form middle power distribution cabinet.And all kinds of floor type handcarts do not carry propulsion and (exit) mechanism, if need to be by mobile handcart in cabinet
In be moved to required position, it is necessary to by propulsive mechanism.The removable class handcart of domestic and international each manufacturer production is multifarious, with it
Supporting propulsive mechanism is also ever-changing, but changes ten thousand times without leaving the original aim or stand, and is all T-type structure, the middle pressure exchange as disclosed in Chinese patent
Shelter-clad removal switch cabinet chassis handcart for middle arranged vacuum circuit breaker (patent No. ZL200520119690.9, publication date 2007
On January 10, in), electric chassis vehicle transmission assembly disclosed in Chinese patent (patent No. 200910102191.1, publication date 2010
March 3), press the screw rod of AC metal armored withdraw-type switch cabinet chassis handcart for middle arranged vacuum circuit breaker to be located in one of which
On the center of crossbeam, the push rod of electric chassis vehicle transmission assembly is located at the left side of crossbeam, but crossbeam and screw rod be all on the whole
It is to form T-type structure.So-called T-type structure refers to；Crossbeam is fixed on cabinet by the latch at both ends, the middle part installation spiral shell of crossbeam
Bar, nut transmission mechanism, rotary screw makes to be arranged on handcart top nut equivalent to cross beam movement, horizontal so as to drive handcart to move
Beam and screw type such as T words.
The nut and augering screw of existing propulsive mechanism are all arranged in handcart, to avoid the parts in handcart, they
Often not in the symmetrical centre position of crossbeam, electric chassis vehicle transmission assembly described above, but deviate one section of crossbeam midpoint away from
From.Under this asymmetrical stressing conditions, the advancing resistance of thrust and handcart of screw rod can produce larger moment of torsion, moment of torsion
Handcart can be deflected.So when handcart moves, one in front and one in back synchronism is very poor at handcart or so end, it could even be possible to being press-fitted in occurring
The valve of electric cabinet contact box is not opened or finger of breaker can not inject the situation of contact box.Therefore existing propulsive mechanism has
The shortcomings that following：Firstth, pushnut is connected with several screws with handcart, in the case where crossbeam is not inserted into cabinet, can on
Under rock from side to side and rotate, so crossbeam can only be parked on the bracket of handcart, can not shake at all and carry out five anti-interlockings from handcart
Debugging；Secondth, structural integrity is bad, and pushnut and augering screw are all arranged in handcart and also brought very to installation and maintenance
Big inconvenience, it is just more difficult to install electric operating additional, because hand interior space is very narrow crowded, and designs base in original structure
It is also more difficult to increase manual and electric automatic transfer equipment on plinth；3rd, force-bearing situation is very bad, and crossbeam is fixed to by both ends latch
On cabinet, screw rod can produce very high pulling torque, crossbeam is easily deformed in the middle part stress of crossbeam under drag effect.Therefore it is right
The rigidity of crossbeam has higher requirement；4th, Adapter Property is poor, is installed because propulsive mechanism needs to coordinate with chassis vehicle, chassis
Car need to be reserved for the space that augering screw passes through, the chassis vehicle needed on different breakers, not even with the bottom of manufacturer production
Reserved space on jiggering is different, and the propulsive mechanism of chassis vehicle is required to debug during assembling；6th, augering screw, crossbeam
It is easily deformed, because handcart weight is acted on augering screw, augering screw is acted on crossbeam, and augering screw is easily deformed,
Augering screw easily causes beam deformation with torsion caused by crossbeam；7th, augering screw is long, and installation is inconvenient so that disconnected
Road device handcart movement is slow and potential safety hazard be present；In a word, although T-shaped propulsive mechanism is simple in construction, reliability is very poor, installation and
Inconvenient maintenance.
