Abstract
The utility model discloses a matched accessory of a handcart type medium-voltage switch cabinet-a running trolley of a main breaker, which consists of a body (9), and a tray (1) supporting the main breaker; the tray is supported on the body through a horizontal lifting mechanism; the horizontal lifting mechanism consists of grooved long plates (10), a middle plate bracket (11) as well as adjusting screws (14) and nuts (15); the two grooved long plates are symmetrically hinged between two side frames of the middle plate bracket; the upper ends of the grooved long plates are hinged with two sides of the tray, and the lower ends of the grooved long plates are provided with rollers which can roll back and forth in long waist holes at two sides of the body; the corresponding upper ends of the two side frames of the middle plate bracket are provided with rollers which can roll back and forth in long waist holes at two sides of the tray; the front and rear ends of the adjusting screws and nuts are supported on a shaft sleeve (18) at the bottom of the tray; and two sides of the nuts are provided with cams which are hinged with the middle plate bracket. An included angle between the middle plate bracket and the grooved long plates is changed by rotating the screws, thereby being capable of horizontally adjusting the height of the tray; moreover, the tray has good rigidity, is not deformed, can be conveniently adjusted, and has high efficiency.
Description
Affiliated technical field
The utility model relates to a kind of running car of supporting auxiliary-line circuit breaker of handcart-type Medium Voltage Switchgear.
Background technology
The running car of prior art, the pallet that is held line circuit breaker by car body and holder constitutes, pallet overlaps independently by 4, and bolt and nut is supported on the car body, pallet height relies on this group screw device to adjust separately, shows the adjusting inefficiency of this its pallet height of structures shape as Fig. 1, regulate inconvenient, and be difficult to guarantee that four on pallet adjusts point in a horizontal surface, cause pallet to be out of shape, rigidity is relatively poor.And the pallet of running car support circuit breaker only depends on the quadruplet screw rod to support, and causes loosening or stripped thread easily, in operation or use, has unsafe hidden danger.
The utility model content
The purpose of this utility model just provides a kind of later-model handcart-type Medium Voltage Switchgear line circuit breaker transfer car(buggy), and its simple speed easy to adjust is fast, and the high conformity of regulating, guarantee the horizontal rise and fall of pallet, the regulating mechanism self-locking, thus reach strong reliable, simple, the fast speed effect of rigidity.
For achieving the above object, the transfer car(buggy) of handcart-type Medium Voltage Switchgear line circuit breaker of the present utility model, the pallet that is held line circuit breaker by car body and holder constitutes, pallet is supported on the car body by a horizontal lifting mechanism, it is characterized in that: described horizontal lifting mechanism is made of middle board mount, flute profile long slab and adjusting feed screw nut, two flute profile long slabs therefrom symmetry are hinged in the middle of two frames of middle board mount, the upper end of flute profile long slab is hinged with the pallet dual-side again, the lower end then be equipped with roller, can be in the long lumbar hole on car body both sides scroll forward and backward; In the corresponding upper end of board mount two frames be equipped with roller, can be in the long lumbar hole of pallet dual-side scroll forward and backward; The leading screw front and back end of regulating feed screw nut is supported on the bearing of tray bottom, and the both sides of nut have protruding axle hinged with middle board mount.
The kinematic sketch of lifting mechanism as shown in Figure 2, part 1 is a pallet, part 7 is the mounting plane of car body, lever 2 middle parts are connected with hinge with lever 3 middle parts, lever 2 one ends are connected with pallet 1 by fixed hinge, and the other end is connected with slide block 8 by movable hinge, and lever 3 one ends are connected with fixed hinge with mounting plane, the other end is connected with T-nut 5 by movable hinge, and firmware 4 is fixed on screw mandrel 6 on the pallet 1.
Concrete transmission principle is summarized as follows: descend as pallet 1: then during leading screw 6 clickwises, driving T-nut 5 moves right, logical hinge connects, lever 3 moves right, pallet 1 right-hand member moves down, lever 2 is connected through the hinge with lever 3 simultaneously, and slide block 8 moves right, and pallet 1 left end also moves down.Rise as pallet 1, then leading screw 6 contrarotations are got final product.The rise and fall of pallet are that level is carried out.
So the handle rotating threaded shaft seesaws nut by shaking into, thereby board mount changes the height that can adjust the pallet of running car with the angle of flute profile long slab in the drive.
The beneficial effects of the utility model are: owing to adopt a cover leading screw nut to control the height of lift car, and the each point of adjusting is synchronous, and the pallet good rigidity is not yielding, so efficient raising, easy to adjust, convenient aspect in-use performance, quick, reliable.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in the figure, the transfer car(buggy) of handcart-type Medium Voltage Switchgear line circuit breaker of the present utility model, the pallet 1 that is held line circuit breaker by car body 9 and holder constitutes, pallet 1 is supported on the car body 9 by a horizontal lifting mechanism, horizontal lifting mechanism by flute profile long slab 10, middle board mount 11, and regulate leading screw 14, nut 15 constitutes, two flute profile long slabs therefrom symmetry are hinged in the middle of two frames of middle board mount, the upper end of flute profile long slab is hinged with the pallet dual-side again, the lower end then be equipped with roller, can be in the long lumbar hole on car body both sides scroll forward and backward; In the corresponding upper end of board mount two frames be equipped with roller, can be in the long lumbar hole of pallet dual-side scroll forward and backward; Leading screw 14 front and back ends of regulating feed screw nut are supported on the axle sleeve 18 of the front of tray bottom and stay bearing plate 17, and the both sides of nut 15 have protruding axle hinged with the slider support bent plate 16 on the middle board mount, and the front end of leading screw 14 is square toes, is equipped with to shake into handle 19.
By shaking into handle rotational lead screw, the relative pallet of nut produces displacement, and nut drives slider support plate, middle board mount again, thereby has changed the angle of middle board mount and flute profile long slab, and the circuit breaker pallet can raise or reduce.
