[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 6 A portable electric transfer vehicle for high and low voltage switch cabinets includes an electric transfer vehicle body 1 for transporting high and low voltage switch cabinets.

A plurality of anti-skid protrusions are provided on the upper surface of the bearing platform 2. The bearing platform 2 is pushed to the bottom of the high and low voltage switch cabinets, and then the bearing platform 2 is lifted up by the electric transfer vehicle body 1 to realize the transportation of the high and low voltage switch cabinets. The anti-skid protrusions can increase the friction and improve the stability during transportation.

[0033] In order to improve the flexibility during transportation, in this embodiment, a rotating mechanism 3 is arranged between the electric transfer vehicle body 1 and the supporting platform 2; the rotating mechanism 3 includes a driving motor 31, a meshing driving gear 32 and a driven gear 34, and a swivel seat 33 welded and installed on the lower surface of the supporting platform 2 and rotatably connected to the upper surface of the electric transfer vehicle body 1; through the transmission cooperation of the driving motor 31, the driving gear 32 and the driven gear 34, the rotation of the high and low voltage switch cabinets can be realized.

[0034] In order to improve the meshing effect between the driving gear 32 and the driven gear 34, a lubrication part is provided on the upper surface of the electric transport vehicle body 1, and the lubrication part is composed of a lubrication mechanism 5 and an oil delivery mechanism 6;

[0035] The lubrication mechanism 5 includes a lubrication cylinder 51, a transmission shaft 52 rotatably installed inside the lubrication cylinder 51, and a stirring rod 53, the bottom end of the transmission shaft 52 is connected and fixed to the output shaft of the drive motor 31, the top end of the stirring rod 53 extends to the outside of the lubrication cylinder 51, and a connecting block 54 is rotatably installed on the top end of the stirring rod 53, and a return spring 55 is fixedly installed between the connecting block 54 and the lubrication cylinder 51, and a connecting arm 56 is fixedly installed on the upper surface of the connecting block 54, and a contact roller 57 is rotatably installed at one end of the connecting arm 56; a mounting frame 4 is bolted on the upper surface of the electric transfer vehicle body 1 and located on one side of the drive motor 31, and the lubrication cylinder 51 is fixedly installed on the mounting frame 4.

[0036] The oil delivery mechanism 6 includes a pump housing 61 fixedly mounted on the outer surface of the lubrication cylinder 51, a valve housing 62 fixedly connected to the outer surface of the opposite side of the pump housing 61, a piston block 63 slidably arranged inside the pump housing 61, and a piston rod 64 fixedly mounted on the upper surface of the piston block 63 and extending to the outside of the pump housing 61. Check valve plates 65 are elastically hingedly mounted in the two valve housings 62, a connecting plate 68 is installed between the top end of the piston rod 64 and the connecting arm 56, and the two valve housings 62 are fixedly connected with connecting pipes 66 at one end away from each other, and one of the connecting pipes 66 is fixedly connected to the lubrication cylinder 51, and an output head 67 is threadedly mounted on the end of the other connecting pipe 66; an arc-shaped abutting seat 7 abutting against the abutting roller 57 is installed on the lower surface of the support platform 2, and the abutting roller 57 is rollingly connected to the outer surface of the arc-shaped abutting seat 7.

[0037] Specifically, the driving gear 32 is fixedly mounted on the output shaft of the driving motor 31, and the driven gear 34 is fixedly mounted on the outer surface of the rotating seat 33. The driving gear 32 and the driven gear 34 are of different sizes. The transmission shaft 52 is a spline shaft, and a spline groove matching the spline shaft is provided inside the stirring rod 53. The transmission shaft 52 and the stirring rod 53 are both connected to the bearing inside the lubricating cylinder 51. Through the sliding fit between the spline shaft and the spline groove and the deformation of the return spring 55, the stirring rod 53 is reciprocated up and down, thereby stirring the lubricating oil in the lubricating cylinder 51 and improving the activity of the lubricating oil.

[0038] In this embodiment, the return spring 55 surrounds the top outer surface of the stirring rod 53, and the stirring rod 53 is sleeved on the outer surface of the transmission shaft 52.

The working principle of the oil delivery mechanism 6 is the piston pump principle. When the stirring rod 53 reciprocates up and down, the piston rod 64 is driven up and down by the connecting plate 68, so that the piston block 63 reciprocates in the pump chamber, thereby changing the pressure in the pump chamber to realize oil pumping. The extracted lubricating oil is transported through the output head 67 and sprayed to the connection between the driving gear 32 and the driven gear 34 to realize lubrication, ensure the stable lubrication drive of the driving gear 31 and the driven gear 32, and improve the adjustment stability of the support platform 2.

[0041] The working principle of the above embodiment is:

[0042] When in use, push the carrying platform 2 to the bottom of the high and low voltage switch cabinets, and then use the electric transfer vehicle body 1 to lift the high and low voltage switch cabinets, so as to realize the transportation of the high and low voltage switch cabinets. When the high and low voltage switch cabinets need to be rotated, the high and low voltage switch cabinets can be rotated by driving the motor 31, the driving gear 32 and the driven gear 34;

[0043] In addition, when the driving gear 32 is meshed with the driven gear 34, the stirring rod 53 is driven to rotate through the transmission shaft 52. Moreover, when the supporting platform 2 rotates, the arc-shaped abutment seat 7 and the abutment roller 57 are abutted and matched, and the deformation of the reset spring 55 is utilized to realize the up and down reciprocating motion of the stirring rod 53, thereby realizing the stirring of the lubricating oil in the lubrication cylinder 51 and improving the activity of the lubricating oil. When the stirring rod 53 reciprocates up and down, the piston rod 64 is driven up and down through the connecting plate 68, so that the piston block 63 reciprocates in the pump chamber, thereby changing the pressure in the pump chamber to realize oil pumping. The extracted lubricating oil is transported through the output head 67 and sprayed to the connection between the driving gear 32 and the driven gear 34 to realize lubrication, ensure the stable lubrication drive of the driving gear 31 and the driven gear 32, and improve the adjustment stability of the supporting platform 2.

In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
