[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 4As shown, embodiment 1 of the utility model is a switch trolley transfer vehicle, comprising a base 1, two support plates 2, two adjustment mechanisms 3 and a guide bar 4. A slide groove 12 is provided on the base 1, and a guide bar 4 slidably connected to the slide groove 12 is provided at the bottom of the support plate 2, and rollers 21 are provided on both sides of the guide bar 4 of the two support plates 2; an adjustment mechanism 3 is provided on the inner side of each support plate 2, and the adjustment mechanism 3 comprises a rotating shaft 31, a paddle 32 and a positioning column 33, the paddle 32 is rotatably connected to the inner side of the support plate 2 through the rotating shaft 31, and a positioning column 33 is vertically arranged at the bottom of the paddle 32, and a plurality of limiting holes 11 compatible with the positioning column 33 are provided on the top of the base 1 along the extension direction of the slide groove 12.

[0021] When it is necessary to adjust the distance between the two pallets 2 to adapt to the switch trolley and switch cabinet of smaller width, flip the paddle 32 outward, pull the positioning column 33 out of the current limit hole 11, select the limit hole 11 that matches the width of the switch cabinet and switch trolley, pull the pallet 2, the guide bar 4 slides in the slide groove 12, the roller 21 rolls parallel to the slide groove 12, flip the paddle 32, insert the positioning column 33 into the selected limit hole 11, repeat the above steps to adjust the other pallet 2, and after the distance between the two pallets 2 corresponds to the width of the switch trolley and the switch cabinet, the switch trolley can be sent into or moved out of the switch cabinet; by setting the rotating shaft 31, the paddle 32 and the positioning column 33, the width of the pallet 2 on the transfer vehicle can be adjusted, so that a transfer vehicle can adapt to a variety of switch trolleys and switch cabinets, with strong adaptability. There is no need to prepare a variety of transfer vehicles of different specifications in the distribution room, saving space resources in the distribution room.

[0022] It should be noted that: the guide bar 4 is used to guide the pallet 2 to move along the slide groove 12, and is also used to support the pallet 2. In a specific implementation, at least two guide bars 4 are arranged at intervals along the slide groove 12 at the bottom of each pallet 2 to improve the support stability; the roller 21 is used to support the pallet 2 and facilitate the movement of the pallet 2; under the support of the guide bar 4 and the roller 21, the pallet 2 can be horizontally stationary.

[0023] Embodiment 2 of the utility model is a switch trolley transfer vehicle, which, based on embodiment 1, further includes a positioning pin 6 and a positioning rod 7. A fixing block 5 is provided in the middle of the front end of the base 1, and a positioning pin 6 is provided at the front end of the fixing block 5. A positioning rod 7 is provided at the front end of each support plate 2, and the positioning rod 7 and the positioning pin 6 are located in the same horizontal plane. The positioning pin 6 is adapted to the socket in the middle of the switch cabinet, and the positioning rod 7 can move with the support plate 2 and adapt to the sockets on both sides of the switch cabinet. After the positioning pin 6 and the positioning rod 7 on the transfer vehicle are inserted into the sockets for positioning, the subsequent operation can be started.

[0024] Embodiment 3 of the present utility model is a switch trolley transfer vehicle, which, based on embodiment 1, further includes a baffle 8, and each support plate 2 is vertically provided with a baffle 8 on the outside to prevent the switch trolley from lateral displacement on the support plate 2 and prevent the switch trolley from falling from the transfer vehicle.

[0025] Embodiment 4 of the present utility model is a switch trolley transfer vehicle, which, based on embodiment 3, further includes a limit screw 9, and a limit screw 9 is arranged on the support plate 2 inside the tail of the baffle 8.
