DETAILED DESCRIPTION The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2 As shown, a high-voltage meter box installation device for a distribution room includes a base 1, as shown in FIG. Figure 5As shown, one end of the base 1 is provided with a rear frame 107, and both sides of the rear frame 107 are connected to side frames 106 connected to the base 1. The width of the side frames 106 is smaller than the length of the base 1, and a lifting mechanism is provided between the two side frames 106. Figure 9 、 Figure 10 As shown, the lifting mechanism includes a main lifting platform 4 that moves up and down along the side frame 106. A lifting basket 2 is connected to one side of the main lifting platform 4. The lifting basket 2 is located above the base 1 and does not extend beyond the base 1. A lifting auxiliary lifting platform 5 is provided at the upper end of the main lifting platform 4. The upper end of the auxiliary lifting platform 5 is provided with a translation seat 6 that can be adjusted left and right. The upper end of the translation seat 6 is provided with a push seat 7 that can move forward and backward. The high-pressure metering box is placed on the upper end of the push seat 7. After being raised to the installation height, the high-pressure metering box can be pushed toward the wall by the push seat 7 for hanging installation (expansion screws for hanging are pre-driven into the wall). The end of the push seat 7 facing the wall can extend from the rear frame 107. When the high-pressure metering box is placed on the push seat 7, the rear end of the high-pressure metering box extends out of the push seat 7, that is, the rear end of the high-pressure metering box is suspended in the air. When the push seat 7 transports the high-pressure metering box forward, the rear end of the high-pressure metering box first contacts the wall.

When the lifting frame is raised, the push rod 301 rests on the roof, positioning the entire device between the roof and the ground, ensuring stability and security during use. When the lifting frame is lowered, it is located outside the side frame 106, allowing it to be stored, reducing the overall height and facilitating movement. The lower ends of the main lifting platform 4 are provided with lifting frames 401 on both sides, and the side walls of the lifting frames 401 are provided with guide wheels for climbing along the side frames 106. Figure 6 As shown, a supporting rod 112 is provided in the side frame 106, and a gear 114 is provided at the upper end of the supporting rod 112 and the side frame 106, and a chain 110 is connected between the two gears 114, and a clearance hole 115 is provided at the upper end of the side frame 106 to cooperate with the chain 110, and a motor 113 for driving the gear 114 is provided on the supporting rod 112. The gears 114 on the two supporting rods 112 can be connected by a rotating shaft to realize the drive of one motor 113, and the lifting frame 401 is connected to the chain 110 through the clamping block 402. The rotation of the chain 110 drives the lifting frame 401 to move up and down, and a vertical second guide rod 109 is provided in the rear frame 107, and a cross bar 407 is provided between the two lifting frames 401. The cross bar 407 cooperates with the second guide rod 109 through a guide ring to further improve the stability of the movement of the main lifting platform 4. A vertical slide groove 111 is provided on the side wall of the vertical rod of the side frame 106. Figure 12 As shown, the guide wheel includes a wheel seat 403 connected to the lifting frame 401. The wheel seat 403 is a right-angle structure and is sleeved on the outside of the vertical rod of the side frame 106. A pulley 404 that cooperates with the slide groove 111 is provided on the wheel seat 403, which can not only realize the positioning and guidance of the main lifting platform 4, but also reduce the friction during the lifting process.

One end of the second screw 504 is connected to a second hand wheel 505. The second screw 504 can be rotated by the second hand wheel 505 to realize the left and right movement of the translation seat 6, thereby adjusting the left and right position of the high-pressure metering box.

[0023] The upper end of the translation seat 6 is provided with a parallel third screw 605 and a slide rod 604, one end of the third screw 605 is provided with a third hand wheel 603, the lower end of the pushing seat 7 is provided with a second nut seat 712 cooperating with the third screw 605 and an ear plate 706 cooperating with the slide rod 604, and the third screw 605 can be rotated by the third hand wheel 603 to realize the forward and backward movement of the pushing seat 7, thereby hanging the high-pressure metering box on the wall.

[0024] like Figure 13 As shown, the upper end of the pushing seat 7 is provided with a guide groove 701 parallel to the third screw 605, and the upper end of the pushing seat 7 is provided with a pushing block 703 and an anti-slip pad 702. The anti-slip pad 702 can prevent wear between the high-pressure metering box and the pushing seat 7. The pushing block 703 is pressed against the front end of the high-pressure metering box to prevent it from sliding. The lower end of the pushing block 703 is provided with a first positioning plate 704 that cooperates with the guide groove 701. The side wall of the pushing block 703 is connected to the first positioning plate 704, and the first positioning bolt 705 is provided on the first positioning plate 704. The position of the pushing block 703 can be limited by the first positioning bolt 705, thereby positioning the high-pressure metering box front and back; as shown Figure 14 As shown, support sleeves 711 are provided on both sides of the lower end of the pushing seat 7, and a telescopic rod 708 is slidably fitted in the support sleeve 711. The end of the telescopic rod 708 is provided with a clamping plate 707 for positioning the high-pressure metering box, and a second positioning plate 709 is provided on the side wall of the pushing seat 7. The second positioning plate 709 is provided with a second positioning bolt 710 for fixing the telescopic rod 708. The two clamping blocks 402 can be used to position the two sides of the high-pressure metering box to prevent left and right movement, thereby ensuring safe use.
