Description
Technical field
The utility model relates to a kind of transportation means, especially relates to a kind of lifting mode transfer car(buggy) that transports circuit breaker.
Background technology
The draw out switchgear cabinet is the equipment that often uses in the commercial production; as indoor metal armoring draw out switchgear cabinet; it is the complete distribution equipment of 3-12 kilovolt three-phase alternating current, 50HZ sectionalized single busbar connection system; have five anti-function and earthing switch chain functions; be mainly used in being subjected to electricity, sending of power plant, industrial and mining enterprises' distribution and electric industry secondary system substation; carrying out the usefulness of control protection, monitoring, is a kind of superior distribution equipment.
Handcart type breaker is a core component in the draw out switchgear cabinet, because circuit breaker volume, weight are bigger, and the middle part of draw out switchgear cabinet settles, and it must use transfer car(buggy) in Installation and Debugging, maintenance replacing process.The effect of transfer car(buggy) is to transport circuit breaker, and makes circuit breaker be convenient to pack into the middle cabinet of draw out switchgear cabinet, thereby the height of transfer car(buggy) is corresponding with the height of switch cubicle.When existing transfer car(buggy) uses: 1. the operator operates 4 rotating disks step by step and regulates effort of aspect ratio; 2. be difficult to again after regulating guarantee that handcart supporting plate level raises or reduction; 3. exist the adjusting range of sizes less when regulating height, the differing heights circuit breaker cart must be used the differing heights transfer car(buggy), causes substation's transfer car(buggy) model and quantity more; 4. there is the not enough phenomenon of transfer car(buggy) stability after the lift adjustment.
The utility model content
In order to address the above problem, the purpose of this utility model provides a kind of simple in structure, and is easy to operate, can avoid the lifting mode transfer car(buggy) of above-mentioned 4 kinds of problems simultaneously.
The technical solution of the utility model is: a kind of lifting mode transfer car(buggy) is characterized in that this transfer car(buggy) comprises upper frame, underframe, stay bearing plate, driving stay bearing plate and actuating device; Wherein, actuating device comprises leading screw, swivel nut, bearing two and bearing seat; Described upper frame internal fixation has beam, on the front end of described upper frame and the described beam described bearing seat is installed all, and described leading screw connects by 2 two bearing seats of described bearing, but and an end of described leading screw stretch out in the outer and socket crank of described upper frame;
Described swivel nut is socketed on the described leading screw; The upper end of described driving stay bearing plate and described swivel nut are hinged, and lower end and described underframe are hinged; The upper end of described stay bearing plate and described upper frame are hinged, and the lower end is arranged in the long ellipse regulating tank on the described underframe, and can slide in described long ellipse regulating tank; Described stay bearing plate is connected by bearing one with described driving stay bearing plate intersection center-point.
Further, the front end of described upper frame is provided with brace panel.
The beneficial effects of the utility model are: 1. this transfer car(buggy) is simple in structure, and adjusted is convenient, the parallel motion control in the time of can guaranteeing lifting again; 2. this transfer car(buggy) has the stronger adaptive capacity to each substation's ground difference in height; 3. this transfer car(buggy) can realize that the circuit breaker cart of various differing heights uses unified transfer car(buggy), and actv. reduces the outfit kind and the quantity of substation's transfer car(buggy).4. effectively strengthen the unstable phenomenon that occurs behind original transfer car(buggy) height adjustment.

The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further.
Be illustrated in figure 1 as the structural representation of a kind of lifting mode transfer car(buggy) of the utility model.A kind of lifting mode transfer car(buggy) comprises upper frame 1, underframe 2, stay bearing plate 3, driving stay bearing plate 4 and actuating device.
Wherein, actuating device comprises leading screw 5, swivel nut 6, bearing 29 and bearing seat 8; Be provided with bearing seat 8 on the front end of upper frame 1 and the beam 13, front end is provided with brace panel 11, is equipped with bearing 29 on the bearing seat 8, and leading screw 5 major parts are installed in the upper frame 1 by bearing 29 and bearing seat 8, and leading screw 5 has an end to stretch out in outside the upper frame, but this end socket crank; Swivel nut 6 is socketed on the leading screw 5, the end and the swivel nut 6 that drive stay bearing plate 4 are hinged, the other end and underframe 2 are hinged, one end and the upper frame 1 of stay bearing plate 3 are hinged, the other end and underframe 2 are hinged, and in long ellipse regulating tank 10, slide, stay bearing plate 3 and described driving stay bearing plate 4 intersection center-points are hinged by bearing 1.Underframe 2 bottoms are provided with cardan wheel 12.
Principle of work of the present utility model:
During the transhipment circuit breaker cart, before transfer car(buggy) is shifted switch cubicle onto, the operator is enclosed within crank at an end that is exposed to the outer leading screw of upper frame, shake crank by handle, drive leading screw 5 rotations, because swivel nut is activated the restriction of stay bearing plate and can't be rotated, so swivel nut parallel motion on screw mandrel, drive and drive stay bearing plate 4, drive stay bearing plate 4 and drive stay bearing plate 3 by bearing 1, the slip of stay bearing plate 3 in long ellipse regulating tank 10 under their combined action, makes upper frame realization ascending, descending and can effectively control the distance of lifting.By being installed in upper frame 1 put the beams in place 13 bearing seat 8 and bearing 29, and upper frame 1 front end brace panel 11 guarantees leading screws 5 maintenance levels during this.
