[0040] The stroller 4 comprises a rectangular stroller body 4-5, and wheels 4-6 and fixing assemblies 4-3 corresponding to the wheels 4-6 are arranged at the four corners of the stroller body 4-5. When the folding safety shielding device is in operation, the wheels are fixed by the fixing assemblies 4-3, and when the folding safety shielding device is moved, the wheels are released from the fixing assemblies 4-3. Specifically, the fixing assemblies 4-3 comprise fixing assembly units arranged at the longitudinal ends of the stroller body 4-5, and each fixing assembly unit comprises anti-skid blocks 4-3a rotatably arranged at the two sides of the longitudinal ends of the stroller body 4-5 by rotating connecting devices 4-3b and corresponding to the wheels 4-6. The rotating connecting devices 4-3b can be hinges, and one side of each anti-skid block 4-3a is provided with a semicircular groove matched with the wheel 4-6. The inner sides of the two anti-skid blocks 4-3a are connected with a connecting rod 4-3d, and the longitudinal ends of the stroller body 4-5 are provided with connecting lines 4-3c, and the front ends of the connecting lines 4-3c are provided with connecting buckles. When the folding safety shielding device is moved, the anti-skid blocks 4-3a at the longitudinal ends of the stroller body 4-5 are rotated outwardly, and the connecting buckles of the two connecting lines 4-3c are connected with the two connecting rods 4-3d, so that the anti-skid blocks 4-3a are prevented from falling when they are moved. At this time, the anti-skid blocks 4-3a do not fix the wheels, and the stroller body 4-5 can be pushed to move by the wheels 4-6. When the folding safety shielding device is used for safety shielding operation, the connecting buckles of the two connecting lines 4-3c are disconnected with the two connecting rods 4-3d, the anti-skid blocks 4-3a at the longitudinal ends of the stroller body 4-5 are rotated inwardly, and the wheels 4-6 are located inside the semicircular grooves of the corresponding anti-skid blocks 4-3a. The folding safety shielding device is supported by the anti-skid blocks 4-3a, so that the folding safety shielding device is prevented from moving.

[0041] In order to facilitate the movement of the stroller 4, as a preferred embodiment, handrails 4-1 are arranged at the two sides of the stroller body 4-5. A “from here” sign can be arranged on one side of the handrail, so as to remind the operator and prevent the operator from walking into the wrong live interval.

[0042] In addition, a storage box 4-4 can be arranged on the handrail 4-1, and a magnetic sign with the words “prohibited climbing, high-voltage danger!” is arranged in the storage box. The magnetic sign can be adsorbed on the adjacent live equipment to be detected, so as to warn the operator and prevent misoperation.

The four corresponding second pin holes 3-1b of the four longitudinal rods 3-1-1 of the two rectangular frames are movably connected by the second pin 3-1a. By rotating the two rectangular frames relative to each other, the height of the overall "X"-shaped support foot 3-1 can be changed, so that the height of the foldable safety shielding device can be adjusted according to the working height. To facilitate installation of the "X"-shaped support leg 3-1 on the vehicle body 4-5, the two transverse rods 3-1-2 at the bottom of the "X"-shaped support leg 3-1 are respectively secured within two transverse slots 4-7 at the top of the vehicle body 4-5. The four longitudinal rods 3-1-1 on either side of the "X"-shaped support leg 3-1 are respectively secured within two longitudinal slots 4-8 at the top of the vehicle body 4-5. To ensure the stability of the "X"-shaped support leg 3-1 on the vehicle body 4-5, as a preferred embodiment, the transverse slots 4-7 formed by the clamping blocks 4-2 are arc-shaped. To increase the wear resistance and friction of the slots, a layer of wear-resistant rubber can be applied to the surfaces of the transverse and longitudinal slots 4-7, 4-8 to enhance friction.

[0045] The support pedal 2 includes a first support pedal 2-1 that is movably mounted on top of an "X"-shaped support leg 3-1. When the first support pedal 2-1 is installed, two fixed seats 2-1a are symmetrically fixed on its bottom, and are rotatably connected to the two transverse rods 3-1-2 on the top of the "X"-shaped support leg 3-1 through the two fixed seats 2-1a. The first support pedal 2-1 has an inner cavity on one longitudinal side and a second support pedal 2-2 that is slidably mounted thereon to match the first support pedal 2-1. This allows operators to extend the working range by stretching the second support pedal 2-2 according to the needs of the operation. The second support pedal 2-2 has "1"-shaped support legs 3-2 correspondingly mounted on both sides of the front bottom of the second support pedal 2-2, and a stable support can be formed by the "1"-shaped support legs 3-2. For ease of marking, the surfaces of the first support pedal 2-1 and the second support pedal 2-2 can also be provided with a "Work Here!" warning to guide the operator's working range.

The first support pedal 2-1 and the second support pedal 2-2 are connected and fixed by the two first pins 2-2a inserted into the two corresponding first pin holes 2-2b of the second support pedal 2-2, so that the extended length of the second support pedal 2-2 can be adjusted according to actual operation needs.

[0046] The shielding device 1 includes shielding units correspondingly arranged on the left and right sides of the support pedal 2. The shielding unit includes two shielding rods 1-4 respectively arranged on the top of the rear end of the first support pedal 2-1 and the top of the front end of the second support pedal 2-2.

The retraction device 1-1 is movably connected with the shielding belt 1-2. The front end of the shielding belt 1-2 passes through the limiting component 1-5 and is provided with a shielding magnet 1-3. The limiting component 1-5 is used to block the shielding magnet 1-3. The shielding magnet 1-3 uses a strong magnetic magnet to facilitate the formation of a strong magnetic force between the metal shell of the equipment to be repaired, and can play a good adsorption and fixing role, so that the shielding rods 1-4 and the shielding belt 1-2 can form a tight isolation shielding.

[0047] As a preferred implementation method, the shielding belt can be an elastic belt with a sign "Stop, high voltage danger!" on the surface.
