Abstract
A handcart-type high-voltage switch cabinet comprises a cabinet body with the middle part provided with a middle-positioned track, a functional handcart and a chassis cart, wherein, the lower end of the chassis cart is provided with wheels while the upper end is fixedly connected with a static cart frame; a shaker propulsion screw which can rotate around the own medial axis is arranged on the static cart frame; a locking device used to lock with the cabinet body mutually is arranged on the chassis cart; the functional handcart is positioned above the chassis cart; the lower end of the functional handcart is provided with a roller coordinated with the middle-positioned track on middle part of the cabinet body and a thread sleeve having an inner thread; the shaker propulsion screw is encased in the thread sleeve and coordinated with the inner thread of the thread sleeve. When the handcart is shifted and pushed integrally, the functional handcart is fixed on the chassis cart, which is as stable and flexible as a common floor type handcart, and has very high accuracy when being inserted to a working position.
Description
(1) technical field
The utility model relates to a kind of handcart type high-voltage switch cabinet.
(2) background technology
High-tension switch cabinet can be divided into fixed and withdraw-type two big classes on structure, can remove parts and be commonly referred to as handcart, and therefore, moveable high-voltage switchgear is also referred to as the handcart type high-voltage switch cabinet.3.11 couples of GB3906 " 3～35kV ac metal closing switch gear " can remove parts and be defined as " parts that can remove fully and can replace, no exception when major loop is charged " from metal enclosed switchgear.According to the function needs, the configurable circuit breaker cart of the parts removed of switchgear, voltage transformer handcart, isolation handcart, lightning arrester handcart, fuse handcart and house transformer handcart etc., consumption with circuit breaker cart in the actual use engineering serves as maximum, the handcart of same type can exchange use, is convenient to equipment replacement and maintenance.
As shown in Figure 1, general high-tension switch cabinet handcart all lands, handcart has test/open position and service position in high-tension switch cabinet, all there is positioner each position, roller is housed on the handcart, can move on the guide rail in switch cubicle, this handcart moves on the ground and pushes away also relatively steadily.But this console mode handcart structure is huge, and the insertion precision of insulating contact is accurate inadequately.
As shown in Figure 2, a kind of in addition " middle " handcart high-voltage switch cabinet, function handcart are at the medium position of switch cubicle, and the function handcart will advance or withdraw from switch cubicle and all want the service firing car to load when indoor transhipment, and the running car does not enter switch cubicle." middle " handcart is compared with " console mode " handcart, compact conformation, and overall dimension is little, so the accuracy of manufacture is higher, guarantees the insertion precision of insulating contact easily, so the use of middle high-tension switch cabinet is more and more welcome.But the function handcart just simply locks on the running car, and center of gravity is very high, therefore is not suitable for remote implementation, especially is not suitable for carrying out on uneven ground, otherwise topples over easily.
(3) summary of the invention
For the insertion precision that overcomes console mode wheelbarrow switch cabinet handcart insulating contact in the prior art accurate inadequately, and the handcart of middle handcart high-voltage switch cabinet moves the deficiency of the shortcoming of stationarity when pushing away outside cabinet, the utility model provide a kind of handcart insulating contact the insertion precision accurately, outside cabinet, move the handcart type high-voltage switch cabinet that stationarity is good when pushing away.
The technical scheme in the invention for solving the technical problem is: a kind of handcart type high-voltage switch cabinet, comprise cabinet and function handcart, the middle part of described cabinet is provided with mid-track, also comprise the chassis car, car lower end, described chassis is equipped with wheel, the upper end of described chassis car is connected with quiet vehicle frame, and described quiet vehicle frame is provided with and can shakes into screw rod around what self axis rotated, and described chassis car is provided with and is used for the locking device that locks mutually with cabinet; Described function handcart is positioned at the top of described chassis car, the lower end of described function handcart is provided with roller and thread bush, described roller cooperates with the mid-track at described cabinet middle part, described thread bush has internal thread, described shake in the cover of screw rod into and the described thread bush and with the screw-internal thread fit of thread bush.
Further, described shake into screw rod by Bearing Installation on described quiet vehicle frame.
Further, described locking device is the latch that is inserted on the car of described chassis, offers the lockhole that cooperates with described latch on the described cabinet.
Further, described quiet vehicle frame is fixed on the upper end of described chassis car by hold-down screw.
Handcart integral body outside cabinet moves that the function handcart is fixed on the car of chassis when pushing away, and is steady, flexible as the common handcart that lands.Handcart enters switch cubicle test/open position chassis car and is locked by locking device, continue when the shift-in of service position, and the roller of function handcart enters the mid-track on the cabinet, and screw rod is advanced into the service position with the function handcart by shaking into.
The beneficial effects of the utility model are: handcart integral body outside cabinet moves that the function handcart is fixed on the car of chassis when pushing away, and is steady, flexible as the common handcart that lands.When being inserted into the service position, has very high accuracy again.

Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of handcart at test/open position.
Fig. 3 is the schematic diagram of handcart in the service position.
Fig. 4 is the structural representation of quiet vehicle frame.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1,2,3,4, a kind of handcart type high-voltage switch cabinet, comprise cabinet 1, function handcart 2 and chassis car 3, the middle part of described cabinet 1 is provided with mid-track 4, car 3 lower ends, described chassis are equipped with wheel 5, and the upper end of described chassis car 3 is connected with quiet vehicle frame 7 by hold-down screw 6, are equipped with and can shake into screw rod 9 around what self axis rotated by bearing 8 on the described quiet vehicle frame 7, be inserted with latch on the chassis car 3, offer the lockhole that cooperates with described latch on the cabinet 1.
Handcart integral body outside cabinet moves that function handcart 2 is fixed on the chassis car 3 when pushing away, and is steady, flexible as the common handcart that lands.When handcart enters switch cubicle test/open position, latch inserts the lockhole on the cabinet, and chassis car 3 is locked, continue when the shift-in of service position, the roller 10 of function handcart 2 enters the mid-track 4 on the cabinet, and screw rod 9 is advanced into the service position with function handcart 2 by shaking into.
