Detailed ways

In order to clearly explain the technical features of this solution, this solution will be described below through specific implementation methods.

A convenient electric meter box lifting device consists of five parts: a bottom support mechanism 1, a top support device 2, a telescopic mechanism 3, a driving mechanism 4 and a hoisting mechanism 5.

As shown in Figure 1, the inclined telescopic mechanism 3 is the main body of the entire device, which is mainly composed of two mutually nested steel pipes. The lower end of the telescopic mechanism 3 is connected to the bottom support mechanism 1, and the upper end is connected to the top support mechanism 2. The bottom steel pipe is A driving mechanism 4 is welded, and the driving mechanism 4 controls the height of the hoisting mechanism 5 by controlling the winding degree of the wire rope 9 .

As shown in Figure 2, the bottom support mechanism 1 is a support plate A101 with a length of 60 cm, a width of 6 cm, and a height of 3 cm. There are through holes on both sides of the support plate A101, which allows the expansion bolts 102 to pass through. The two expansion bolts 102 connect the entire The device is fixed on the ground 6 to ensure that it does not collapse.

As shown in Figure 3, the top support mechanism 2 includes a support plate B201 with a length of 60 cm, a width of 6 cm, and a height of 3 cm and a soft rubber plate 202 of the same length and width. The thickness of the soft rubber plate 202 can be selected according to the actual situation, and its bottom surface is The wall A7 is in contact with each other to increase friction and prevent the device from slipping on the vertical wall.

As shown in Figure 4, the telescopic mechanism 3 mainly consists of a bottom tube 301 nested with a top tube 302 and a steel hook 305 welded on the top tube 302. The top tube 302 and the bottom tube 301 are penetrated by through holes of the same size and spacing. 303, the clamping bolt 304 can be passed through the outer bottom tube 301 and the inner top tube 302, thereby fixing the length of the extended top tube 302; the wire rope 9 passes through the steel hook 305, and steel wires of different heights can be selected according to the actual situation. Hook 305, because the steel hook is triangular, it is helpful to adjust the left and right position of the wire rope, and can also prevent the wire rope from falling off.

As shown in Figures 5 and 6, the overall frame of the driving mechanism 4 is in the shape of an isosceles trapezoid. The upper and both sides of the trapezoid are formed by bending and welding steel pipe A401, and the bottom and upper sections of the isosceles trapezoid are formed by angle iron 402. An isosceles trapezoidal frame with a wide base is welded below the bottom tube (301); the two steel sleeves are in the same horizontal position and are passed through by the cradle 407. The cradle 407 is welded with a pinion 408, and the column tube 404 is covered by the steel pipe B403 The column pipe 404 can slide left and right on the steel pipe B403. The steel pipe B403 and two steel sleeves 406 are welded to the two side bottoms of the isosceles trapezoid. The large gear 405 on the column pipe 404 and the small gear on the rocker 408 mesh with each other; a "6"-shaped buckle 409 is nested on the top edge of the steel pipe A401. (In this embodiment, according to the way the wire rope is wound, the buckle must be "6" from the right view. font, not "∂" font), the buckle can be freely rotated and moved left and right on the steel pipe 401.

As shown in Figure 8, the hoisting mechanism 5 is composed of two vertical fixed blocks 502 connected by a horizontal steel pipe C. The steel wire rope 9 is fixed in the middle of the steel pipe C501. The fixed blocks 502 are hollow square tube structures, and a crane is installed below. Hook 503, the hook 503 passes through the angle iron 504. There are round holes and round slotted holes on both sides of the angle iron 504 to facilitate installation and adjustment of the fixed position. The lower end surface of the angle iron 504 and the top surface of the meter box 10 are connected by bolts. connect.

Steps:

As shown in Figures 1 to 8, the meter installer first brings the device in a retracted state to the working position, which is the ground 6 and the vertical wall A in the picture, and then selects the appropriate installation height according to the wall A, and adjusts the The telescopic length of the top tube 302 and the bottom tube 301 in the telescopic mechanism 3 of this device is fixed with at least two bolts 304; then the steel wire rope 9 fixed on the left end surface of the column tube 404 is lengthened and passed through several suitable steel wires. Hook 305, fix the other end of the wire rope 9 on the lifting mechanism 5, and then fix the lifting mechanism 5 on the top surface of the meter box 10 through bolts. At this time, the meter box is placed on the ground, and the installer leans the lifting device On the wall A to be installed, due to the extrusion deformation of the soft rubber plate 202 and the friction resistance of the rubber itself, it can be temporarily fixed. At this time, the expansion bolt 102 is driven into the ground 6 through the support plate 101, and the entire device is The installation is completed; the installer slightly slides the column tube 404 left and right to engage the large and small gears with each other, and at the same time moves the buckle 409 to the back to prevent the small gear 408 from being stuck, as shown in Figure 6, rotate the crank 407 counterclockwise, and the large gear 405 It is driven clockwise, so that the length of the wire rope 9 on the column tube 404 is getting longer and longer, driving the meter box 10 to rise. After the meter box 10 rises to the designated height, stop rotating the rocker, and at the same time turn back the buckle 409 To the front, the small gear 408 is stuck. Due to the gravity of the meter box 10, the large gear 405 will rotate counterclockwise, which will then cause the small gear 408 to rotate clockwise. However, as shown in Figure 7, the longest outer diameter of the small gear 408 The sum of the diameter r3 and the longest radius r2 of the buckle is greater than the center distance h1, and the three sides are fixed to form a stable triangle. Therefore, the gravity of the meter box 10 will not cause the wire rope 9 to rewind due to the presence of the buckle 409. At this time The lifting operation of the meter box is completed. The installer can then use the straight ladder to climb up the wall A 7 to install it. At the same time, the meter box can also be rotated horizontally 90 degrees and installed on the wall B 8.
