Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention.

As shown in fig. 1, it is a front view of the rotatable transformer positioning trolley according to the embodiment of the present invention; as shown in fig. 2, is a front view of the cart panel according to the embodiment of the present invention. A rotatable transformer in-place trolley comprises an in-place trolley main body, wherein the in-place trolley main body is fixedly connected with a trolley panel 2, and a first circular through hole 6 is formed in the center of the trolley panel 2 according to the requirement of transformer in-place operation. The edge position of the trolley panel 2 is provided with more than two first bolt holes 7, the middle position of the trolley panel 2 is provided with more than two second bolt holes 8, internal threads are arranged in the second bolt holes 8, and the trolley panel 2 is fixedly connected with the transformer box bottom 5 through the first bolt holes 7 by utilizing bolts.

Because the diameter of first round through-hole 6 is generally far greater than the diameter of common connecting bolt's screw rod cap, so, make the dolly of taking one's place unsettledly rotate for through high strength connecting bolt 1, the utility model discloses lower surface at dolly panel 2 has set up the jam plate. The lower fixed surface of dolly panel 2 sets up the jam plate, the central point of jam plate put and set up second circle through-hole, set up the fourth bolt hole in the jam plate with the position that second bolt hole 8 corresponds, utilize the bolt with jam plate and dolly panel 2 fixed connection through fourth bolt hole and second bolt hole 8, pass second circle through-hole and first circle through-hole 6 with connecting bolt 1, connecting bolt 1's screw rod and transformer bottom of the case 5 fixed connection, the diameter of connecting bolt 1's screw cap is less than the diameter of first circle through-hole 6 and is greater than the diameter of second circle through-hole, leaves the space between the screw cap of jam plate and connecting bolt 1 in vertical direction. The locking plate is connected with the trolley panel 2 and then integrally connected with the transformer. The connecting bolt 1 is selected according to the overall weight of the trolley, and the strength of the connecting bolt is required to meet the requirement that the trolley is hung in place vertically in a suspended mode and can bear certain impact.

As a preferred embodiment, the lock plate is formed by combining a right lock plate 3 and a left lock plate 4, and the right lock plate 3 and the left lock plate 4 are identical in structure and are symmetrically combined to form the lock plate. As shown in fig. 3, is a front view of the right lock plate according to the embodiment of the present invention. The right locking plate 3 is of a rectangular flat plate structure, a semicircular notch is formed in one end, in contact connection with the left locking plate 4, of the right locking plate 3, and the diameter of the semicircular notch is slightly larger than that of a screw rod of the connecting bolt 1 and smaller than that of a screw rod cap of the connecting bolt 1; the other end of the right lock plate 3 is provided with a third bolt hole 9, two long bolt holes 10 are formed between the semicircular notch and the third bolt hole 9, and the long bolt holes 10 can ensure that the right lock plate 3 has a certain drawing stroke.

The utility model discloses a theory of operation is: the right locking plate 3 and the left locking plate 4 are firstly connected with the trolley panel 2 of the roller trolley, but the right locking plate 3 and the left locking plate 4 are not fastened firstly, so that the right locking plate 3 and the left locking plate 4 are ensured to have certain drawing stroke. Secondly, a high-strength connecting bolt 1 is installed on a transformer box bottom 5 of the transformer body, a screw cap of the connecting bolt 1 penetrates through a first round through hole 6 on the trolley panel 2 and semicircular gaps of the right locking plate 3 and the left locking plate 4, and the trolley in place is fixedly connected with the transformer box bottom 5 through a first bolt hole 7 on the trolley panel 2 by utilizing a bolt. And finally, sliding the right locking plate 3 and the left locking plate 4 towards the middle to enable the two to be in contact connection and to coat the bolt rod of the high-strength connecting bolt 1, and fixedly connecting the right locking plate 3 and the left locking plate 4 with the trolley panel 2 through a second bolt hole 8 and a long bolt hole 10 on the trolley panel 2 by using bolts, wherein a certain gap is formed between the right locking plate 3 and the left locking plate 4 in the vertical direction and the screw cap of the high-strength connecting bolt 1. When the transformer needs to change tracks, the transformer box body is lifted upwards by a certain height by using a jack, so that the in-place trolley is integrally suspended, the fastening bolt between the bottom 5 of the transformer box and the panel 2 of the trolley is loosened, the in-place trolley can fall by a certain height, and meanwhile, the gap between the right locking plate 3 and the left locking plate 4 can fall onto the screw cap of the connecting bolt 1. At the moment, the screw cap of the high-strength connecting bolt 1 can abut against the gap between the right locking plate 3 and the left locking plate 4, the suspension of the transformer in-place trolley is realized through the combined action of the right locking plate 3 and the left locking plate 4 and the high-strength connecting bolt 1, the trolley panel 2 and the transformer box bottom 5 are not interfered with each other, then the conversion track of the transformer in-place trolley can be easily rotated, the in-place trolley is always connected with the transformer through the connecting bolt 1, and the in-place efficiency is greatly improved.

Finally, it is to be noted that: the above embodiments are only specific embodiments of the present invention, and are not intended to limit the technical solutions of the present invention, and the scope of the present invention is not limited thereto. Those skilled in the art will understand that: any person skilled in the art can modify or easily conceive the technical solutions described in the foregoing embodiments or equivalent substitutes for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
