[0024] See also Figure 1-5A GIS equipment accessory on-site installation vehicle comprises two sets of parallelly arranged base frames 1, the bottom of each set of base frames 1 is provided with a first wheel 2 for moving the base frames 1, the first wheels 2 are two respectively arranged at the two ends of the bottom of the base frame 1, the top of the base frame 1 is provided with a mounting beam 3, the bottom of the mounting beam 3 is slidably provided with a hoist 4, when moving in a narrow space, the first wheel 2 is driven by a driving device to rotate, so that the low frame 1 drives the top mounting beam 3 to move, and the GIS equipment accessories can be lifted by the hoist 4, wherein the hoist 4 adopts a hoist equipped with a hook commonly found on the market, such as Longhai Lifting Tools Co., Ltd., the intelligent lifting device model NOLD-IL, one side of the base frame 1 is provided with a reinforcing rib 5, which plays a role in improving the overall compression resistance of the installation vehicle.

[0025] A reversible support frame 6 is hinged on the side of the base frame 1 away from the reinforcement rib 5, and a second wheel 61 is arranged at the bottom of the reversible support frame 6. A receiving groove 11 for accommodating the reversible support frame is opened on the side of the base frame 1 in the horizontal direction, and a first channel 12 for passing the reversible support frame 6 begins to be provided on the side of the base frame 1 in the vertical direction. The reversible support frame 6 is rotated and stacked into the receiving groove 11 through the first channel 12. When the reversible support frame 6 and the base frame 1 are required to play a supporting role at the same time, the reversible support frame 6 can be flipped to the side away from the reinforcement rib 5. After being fixed by the channel steel 7, the second wheel 61 is in contact with the ground. At this time, the three wheels are in contact with the ground, which improves the stability of the installation vehicle.

[0026] A channel steel 7 slidably connected to the base frame 1 is provided on one side of the reversible support frame 6, and a limit block 8 is provided at one end of the channel steel 7. The limit block 8 and the channel steel 7 slide simultaneously in the second channel 13 opened inside the base frame 1. When the reversible support frame 6 is fixed, the limit block 8 contacts the step portion 14 integrally provided at one end of the second channel 13 close to the first channel 12, limits the limit block 8, and then the channel steel 7 and the reversible support frame 6 are fixedly connected by bolts to achieve the fixation of the reversible support frame 6.

[0027] Furthermore, in order to prevent the flippable support frame 6 from contacting the reinforcing rib 5 during the flipping process, the distance between the center of the hinged portion of the flippable support frame 6 and the base frame 1 and the other end of the flippable support frame 6 is smaller than the shortest distance between the center of the hinged portion of the flippable support frame 6 and the base frame 1 and the reinforcing rib 5.

[0028] Embodiment 1: Now take a certain indoor project as the implementation object for further explanation. In the construction environment, one end of the GIS equipment is 1474mm away from the wall. The voltage transformer weighs about 0.5 tons and needs to be hoisted more than 2 meters high. The chassis needs to be long enough to ensure the stability of the chassis. After measurement, the minimum chassis length is required to be 1700mm. Therefore, the horizontal part of the designed installation vehicle chassis 1 and the reversible support frame 6 are fixed by the channel steel 7. The total length is 1700mm, of which the reversible support frame 6 is 600mm long. When it is necessary to enter between one end of the equipment and the wall, it is necessary to Remove the bolts that fix the flip support frame 6 and the channel steel 7, flip the flip support frame 6 into the accommodating groove 11, and finally push the channel steel 7 into the second channel 13. At this time, the length of the chassis of the installation vehicle is 1100 mm, and it can enter the wall and one end of the GIS equipment, and then move along the setting direction of the GIS equipment. When hoisting is required, in order to ensure the stability of the chassis of the installation vehicle, the flip support frame 6 is flipped back to its original position and fixed by the channel steel 7. The second wheel 61 contacts the ground, so that the length of the entire chassis of the installation vehicle is restored to 1700 mm, ensuring stability during hoisting.

[0029] When the GIS equipment accessory on-site installation vehicle is used, the distance between one end of the equipment and the wall is narrow and the length of the installation vehicle needs to be shortened. When only the two first wheels 2 of the base frame 1 are in contact with the ground, the reversible support frame 6 is first flipped, first passes through the first channel 12, and finally stacked in the accommodating groove 11, so that the installation vehicle can enter between the equipment and the wall, and continue to move along the setting direction of the equipment. When it reaches the installation position, in order to ensure the reliability during lifting, the reversible support frame 6 is flipped to the other side of the low frame 1, so that the second wheel 61 is in contact with the ground, and then the channel steel 7 is extended from the second channel 13, and the channel steel 7 and the reversible support frame 6 are fixedly connected by bolts, so that the reversible support frame 6 plays a supporting role, extending the length of the chassis of the installation vehicle and improving the stability of the installation vehicle.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
