Embodiment
Following the present invention is further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 3, the present invention mainly comprises that 1, two handcart frame 1 rear end of two handcart frames that are symmetrical set links into an integrated entity by connecting plate 3.Fix respectively a column 26 on two handcart frames 1, each column 26 upper end connects a transmission mechanism support 9, and each transmission mechanism support 9 is provided with a transmission mechanism 2.
The connecting rod 5 that transmission mechanism 2 is connected by an end drives drive lead screw 8 rotations that the other end connects, and drive lead screw 8 one ends are fastened on the bearing pedestal 7 on transmission mechanism support 9.
As shown in Figure 3, described transmission mechanism 2 comprises the first bevel gear 21, the second bevel gear 22, shaft of bevel gear 23, driving chain 24 and the 3rd bevel gear 25, the first bevel gear 21 and the second bevel gear 22 that are connected on connecting rod 5 are connected with a joggle, the second bevel gear 22 connects shaft of bevel gear 23, and shaft of bevel gear 23 upper ends are fixed on transmission mechanism support 9.The second bevel gear 22 is automatically connected in the 3rd bevel gear 25 on drive lead screw 8 by driving chain 24 bands.The gearratio of described the first bevel gear 21 and the second bevel gear 22 is 3:1.The first 21 of bevel gears needs rotate a circle, and the second bevel gear 22 just can rotate three circles, and rapid operation is convenient.
Vertically be provided with lift rail 11 on handcart frame 1.The feed screw nut 13 that is spirally connected on drive lead screw 8, feed screw nut 13 is fixed on and promotes on guide plate 10.Promote guide plate 10 sides and be provided with a plurality of lifting guide wheels 12, a plurality of lifting guide wheels 12 are slidably mounted in lift rail 11.When connecting rod 5 drives drive lead screw 8 rotation by transmission mechanism 2, feed screw nut 13 drives lifting guide plates 10 and moves both vertically along lift rail 11.
Described two handcart frame 1 rear ends are provided with handcart handrail 4, and handcart handrail 4 is convenient for people to promote handcart frame 1.
Described connecting rod 5 one ends connect rocker lever 6, are convenient for people to drivening rod 5 by rocker lever 6 and rotate.
Described two handcart frame 1 lower ends are rotationally connected respectively two rollers 20.
Operation principle of the present invention is: during work, high-voltage switch gear is pushed in supporting bracket 14 by horizontal guide rail 15.Then pivot link 5, and when connecting rod 5 drives drive lead screw 8 rotation by transmission mechanism 2, feed screw nut 13 drives lifting guide plates 10 and arrives the height of high-tension switch cabinet along lift rail 11 vertical lifting.Then rotate bolt rod 17 by latch handle 19, bolt rod 17 front ends eject the connection high-tension switch cabinet, thereby fixed support support 14 pushes high-voltage switch gear in high-tension switch cabinet.In the present invention, the gearratio of the first bevel gear 21 and the second bevel gear 22 is 3:1.The first 21 of bevel gears needs rotate a circle, and the second bevel gear 22 just can rotate three circles, and rapid operation is convenient.Utilize the principle of gearratio, the gearratio by bevel gear is realized lifting heavier object and reaching the height of regulation by lighter power.High-voltage switch gear leads by guide rail, realizes that accurately high-voltage switch gear moves in the high-voltage switch gear cabinet smoothly.Add that handcart structural design volume is little, conveniently moving, to can realize operation preferably in little place, electric substation place.The requirement that the present invention goes back coupling apparatus pushes the wheel on high-voltage switch gear in design with the guide rail location, not only can avoid occurring that displacement can also not there will be inclination and play in moving process and the damage, the hoisting mechanism that cause can realize that by screw mandrel and nut transmission mobile accuracy is high stably.Both sides are moved and adopted square steel is that connecting rod can promote the phenomenon of avoiding occurring the both sides injustice uniformly in same direction.
