Abstract
The utility model relates to a high voltage switch cabinet handcart. A top portion casing wall of a cabinet wall is provided with a spacing hole which penetrates through a wall body, an outer side ring wall face at the cabinet wall top portion wall body which is located around the spacing hole is mounted with a first adjusting nut through external threads, a screw extends into the cabinet wall through the first adjusting nut and the spacing hole, a lower end of the screw which extends into the cabinet wall through the spacing hole is inserted in a positioning sleeve tube and is fixedly connected with the positioning sleeve tube, a cart frame is arranged at an internal portion of the cabinet wall, the positioning sleeve tube is fixedly mounted at a top portion of the cart frame, a lower portion of the cart frame is mounted with a wheel shaft, shaft holes extend along a vertical direction to be in a long-strip shape, two end portions of the wheel shaft are in reciprocating sliding fit with the shaft holes along a length direction of the shaft holes, the two end portions are respectively mounted with second adjusting nuts through the external threads when the two end portions extend out of the cabinet wall through the two shaft holes, and the second adjusting nuts are in contact fit with the outer side ring wall face of two side walls of the cabinet wall located around the shaft holes in a heading mode that the external threads arranged along an end portion of the wheel shaft rotate around the wheel shaft. The high voltage switch cabinet handcart further improves stable and accurate butt-joint performance of moving and static contacts.
Description
Technical field
The utility model relates to equipment for power transmission and distribution, particularly high-voltage switch cubicle handcart.
Background technology
Handcart is the critical piece in the withdrawable switch cubicle, for example deviation often appears when fixed contact on the housing docks in the moving contact on the handcart in the 35KV high-tension switch cabinet, cause this result former because: be that error appears in machining accuracy on the one hand, because basis (ground) injustice on the other hand, thereby make dynamic and static contact in conjunction with bad, some moving contact even can't insert in the fixed contact send electricity to cause very large impact for the check of dispatching from the factory, field adjustable.
The utility model content
The purpose of this utility model is to provide a kind of high-voltage switch cubicle handcart, and is rational in infrastructure, and the wheel high flexible is adjustable, further improves the performance of the steady accurate docking of dynamic and static contact.
The purpose of this utility model is achieved in that a kind of high-voltage switch cubicle handcart, wheel shaft passes the center of circle of wheel and the axis hole that bottom, cabinet wall two side arranges respectively, has the cabinet wall, wheel shaft, wheel, the first adjusting nut, positioning pipe sleeve, screw mandrel, vehicle frame and the second adjusting nut, shell wall is arranging the spacing hole that passes its wall body at the top of cabinet wall, corresponding the first adjusting nut that is installed with around spacing hole on the exterior annular wall around cabinet wall top wall body is positioned at spacing hole, screw mandrel stretches into the cabinet pars intramuralis in the setting mode through the first adjusting nut and spacing hole, the internal thread that the external screw thread that screw mandrel has and the first adjusting nut have movingly, screw mandrel inserts positioning pipe sleeve and affixed with positioning pipe sleeve through the lower end that spacing hole stretches into the cabinet wall, vehicle frame is arranged on the cabinet pars intramuralis, positioning pipe sleeve is packed in the vehicle frame top, the vehicle frame bottom is installed with rotating wheel shaft, axis hole is elongated along vertically extending, its both ends axis body of wheel shaft reciprocatingly slides along the length direction of axis hole and axis hole and cooperates and on two axis holes extend out to both ends axis body outside the cabinet wall the second adjusting nut is installed respectively at it, the external screw thread that the internal thread that the second adjusting nut has and wheel shaft both ends arrange movingly, the mode that the second adjusting nut is advanced around the wheel shaft rotation with the external screw thread that arranges along the wheel shaft end and cabinet wall two side are positioned at the cooperation that contacts of axis hole exterior annular wall on every side.
Characteristics of the present utility model are: the height of handcart wheel (two front-wheels) is adjustable, height adjustment range is between 10 ~ 15mm, according to the docking situation of the dynamic and static contact in the scene height with timely adjustment axletree, make dynamic and static contact reach optimum contacting state.The utility model control method: unclamp first the second adjusting bolt, thereby the turn screw mandrel reaches the present position of regulating wheel and axletree, and then the second adjusting bolt tightened, the position that wheel is fixed on adjust, this regulating step possibly dynamic and static contact of repeated multiple times guarantee reaches optimum contacting state.The utility model is rational in infrastructure, and the wheel high flexible is adjustable, further improves the performance of the steady accurate docking of dynamic and static contact.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that first of the utility model part is looked squarely structural representation (axis hole etc. are not shown);
Fig. 2 is that second of the utility model part is looked squarely structural representation (the second adjusting nut etc. are not shown).
Embodiment
