Abstract
The utility model relates to a handcart-type vacuum circuit breaker. The vacuum circuit breaker comprises a handcart frame and a circuit breaker arranged on the handcart frame. A wheel is arranged on a bottom of the handcart frame. The bottom of the handcart frame is provided with a side plate. The wheel is fixed on an outer side of the side plate through a wheel shaft. A bearing is arranged between the wheel and the wheel shaft. A bending plate covers an upper portion of the wheel. One end of the bending plate is fixed on the side plate and the other end is bended downwardly. The wheel shaft passes through the bending plate. According to the vacuum circuit breaker of the utility model, through additionally arranging a wheel positioning mechanism on the wheel of the handcart, the handcart is not deflected when a switch cabinet is rolled in and exits so that the handcart-type vacuum circuit breaker is reliable.
Description
Technical field
The utility model relates to a kind of handcart type vacuum circuit breaker.
Background technology
Handcart type vacuum circuit breaker is generally installed 4 wheels in the bottom of vehicle frame, to realize circuit breaker shaking into and exiting in metal enclosed switchgear (hereinafter to be referred as switch cubicle).When handcart shakes into and exits in switch cubicle, because there are error in handcart and coordinating of switch cubicle, can cause the skewness of handcart, thereby cause the insertion depth of three-phase Mume flower contact inconsistent, even exist certain one side phase insertion depth not reach the situation of specification requirement.In debug process, often to spend larger energy and time.One of reason that causes deflection be the quality of fit of circuit breaker cart and switch cubicle not high due to.And to improve the quality of fit of circuit breaker cart and switch cubicle, what at first will solve is the problem of circuit breaker cart wheel alignment.Because people are not enough to the cooperation understanding of circuit breaker cart and switch cubicle, do not cause enough attention in the wheel alignment of circuit breaker cart, generally by adding in the wheel both sides, adjust the location that pad is realized wheel, even do not design the axial location of wheel.
Summary of the invention
For the handcart and the not high deficiency that causes easy deflection of switch cubicle quality of fit that overcome prior art, the utility model provides a kind of handcart type vacuum circuit breaker with wheel alignment structure.
The technical scheme in the invention for solving the technical problem is:
A kind of handcart type vacuum circuit breaker, comprise vehicle frame and be arranged on the circuit breaker on vehicle frame, the bottom of described vehicle frame is equipped with wheel, the bottom of described vehicle frame is provided with side plate, described wheel is fixed on the outside of described side plate by an axletree, between wheel and axletree, bearing is set, and the top of wheel also is covered with bent plate, one end of bent plate is fixed on side plate, and the other end is bent downwardly and is worn by described axletree.
As preferably, bearing is provided with 2, is clutch shaft bearing and the second bearing, and clutch shaft bearing and the second bearing lay respectively at the both sides of wheel.
As preferably, be provided with positioning sleeve between bent plate and axletree, the outside locking of positioning sleeve has locking nut.
During installation, bearing is pressed into respectively in the hole of wheel both sides, the positioning sleeve bent plate of packing into, axletree through positioning sleeve, bent plate, bearing, wheel and side plate, is then locked by lock nut respectively.By axletree, wheel is positioned, wheel is positioned on the same level line, and is connected with wheel by bearing, the outside of wheel arranges a bent plate again, and bent plate is located on wheel, has guaranteed that wheel deflection can not occur.
The beneficial effects of the utility model are: the utility model is set up wheel alignment mechanism by the wheel of rival car, and handcart, when switch cubicle shakes into and exits, skewness can not occur, more reliable.
The accompanying drawing explanation
Fig. 1 is part-structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of handcart type vacuum circuit breaker, comprise vehicle frame and be arranged on the circuit breaker on vehicle frame, the bottom of vehicle frame is equipped with wheel, the bottom of vehicle frame is provided with side plate 1, wheel 2 is fixed on the outside of side plate by an axletree 4, the centre of wheel 2 both sides inwardly is provided with groove, be respectively charged into clutch shaft bearing 3 in groove, the second bearing 7, between wheel 2 and axletree 4, by clutch shaft bearing 3, with the second bearing 7, be connected, the top of wheel also is covered with bent plate 8, one end of bent plate 8 is fixed on side plate 1, the other end is bent downwardly and is worn by described axletree 4.Be provided with positioning sleeve 6 between bent plate 8 and axletree 4, the outside locking of positioning sleeve has locking nut 5.
During installation, clutch shaft bearing 3, the second bearing 7 are pressed into respectively in the groove of wheel both sides, positioning sleeve 6 bent plate 8 of packing into, axletree 4 through positioning sleeve 6, bent plate 8, bearing, wheel 2 and side plate 1, is then locked by lock nut 5 respectively.Position by 4 pairs of wheels of axletree, wheel is positioned on the same level line, and is connected with wheel by bearing, the outside of wheel arranges a bent plate again, and bent plate is located on wheel, has guaranteed that wheel deflection can not occur.
The utility model is set up wheel alignment mechanism by the wheel of rival car, and handcart, when switch cubicle shakes into and exits, skewness can not occur, more reliable.
