[0023] like Figure 1-2 As shown, a mobile substation maintenance transport equipment lifting platform device includes a mobile base 1, a support 5, a lifting platform 6, and a lifting mechanism 7. The mobile base 1 has two casters 3 at its front end and two brake wheels 2 at its rear end. Adjustable feet 4 are also provided on the mobile base 1. The support 5 is vertically mounted on the upper surface of the mobile base 1, and the lifting platform 6 is slidably mounted on the support 5. The lifting platform 6 is moved up and down by the lifting mechanism 7. The support 5 includes two vertically mounted guide tubes 52. The lifting platform 6 includes a lifting frame 61, a support plate 62, a back plate 63, mounting plates 64, a fixed shaft 65, and U-shaped wheels 66. The support plate 62 is horizontally mounted on the lifting frame 61, and the back plate 63 is perpendicular to the support plate 62 and mounted on one side of the lifting frame 61. Two mounting plates 64 are arranged on the outer side of the back plate 63. Two fixed shafts 65 are connected between the mounting plates 64, and the two fixed shafts 65 are staggered vertically. Two guide rail tubes 52 are set between the two fixed shafts 65. Two U-shaped wheels 66 are provided on each of the two fixed shafts 65 corresponding to the positions of the guide rail tubes 52. The U-shaped wheels 66 are set in pairs on both sides of the same guide rail tube 52 and are in close contact with the guide rail tube 52. The lifting mechanism 7 includes a winch 71, a wire rope 72, a stationary pulley 73 and a movable pulley 74. The winch 71 is fixed on the movable seat 1. The top of the bracket 5 is provided with a stationary pulley 73. One end of the wire rope 72 is fixed to the top of the bracket 5. The other end of the wire rope 72 passes through the movable pulley 74 and the stationary pulley 73 in sequence and is connected to the winch 71. The back plate 63 is provided with a through hole 67. The movable pulley 74 is also connected to a hook 75, which is hung at the through hole 67.

[0024] The front casters can rotate 360 ​​degrees, facilitating vehicle direction adjustments. Brake wheels secure the vehicle once stopped, preventing movement. Adjusting the outriggers after the vehicle is stationary ensures the vehicle remains level in all directions, guaranteeing chassis stability and preventing rollovers when the load is increased.

[0025] Two guide tubes are located between two U-shaped wheels. When the lifting platform moves up and down, the U-shaped wheels roll on the surface of the guide tubes. The rolling motion reduces friction and is more conducive to the up and down movement of the lifting platform.

[0026] For example, the bracket 5 also includes a flip seat 51, a connecting tube 53 and a crossbar 54. The front end of the flip seat 51 is hinged to the upper surface of the movable seat 1, and the rear end of the flip seat 51 is fixed to the movable seat 1 by bolts. Two guide rail tubes 52 are vertically arranged on the flip seat 51. The two guide rail tubes 52 are connected by several connecting tubes 53 arranged vertically. The top ends of the two guide rail tubes 52 are also connected by the crossbar 54. A stationary pulley 73 is arranged on the crossbar 54.

[0027] The flip stand allows the device to be folded down when not in use, making it easy to store in small spaces.

[0028] Specifically, each end of the crossbar 54 is equipped with a safety hook 8. This can be used to attach safety belt hooks during equipment maintenance and repair in substations.

[0029] For example, the upper surface of the support plate 62 is provided with an anti-slip pad.

[0030] For example, the movable base 1 is provided with four symmetrical extension arms 11 inserted in pairs, and the extension arms 11 are vertically provided with adjusting feet 4, and the adjusting feet 4 are screwed to the extension arms 11.

[0031] For example, the swivel wheel 3 and the brake wheel 2 are solid wheels with a diameter of 20-30 cm. Solid wheels reduce the risk of the wheels deforming and getting stuck in gravel under heavy loads. The slick tires used in the swivel wheel 3 and brake wheel 2 further reduce the resistance caused by uneven gravel surfaces when the vehicle is moving. Larger diameter wheels provide better traction on gravel roads. Combined with gravel sizes of 3-5 cm, good traction means the wheels can overcome obstacles with a smaller impact angle, avoiding getting stuck or experiencing excessive bumps.

[0032] For example, the movable base 1 is provided with a spirit level. By adjusting the adjustable feet to center the spirit level, the movable base 1 is kept horizontal.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
