[0010] Furthermore, the transmission rod is rotatably connected to the outer ladder frame, and the end of the transmission rod extends out of the outer ladder frame and is welded to the hand wheel.

[0011] By adopting the above technical solution, the transmission rod can be conveniently rotated by rotating the hand wheel.

[0012] Furthermore, the gear one is welded to the transmission rod, and the gear one is meshed with the gear two.

[0013] By adopting the above technical solution, the gear 1 rotates under the action of the transmission rod, which drives the gear 2 to rotate, so as to realize the rotation of the screw rod.

[0014] Furthermore, the screw rod is rotatably connected to the outer ladder frame, the screw rod is welded to the second gear and the screw rod is located in the receiving groove.

[0024] In order to solve the problem that the existing portable electric power construction lift can realize convenient lifting and lowering adjustment between the fixed part and the telescopic part of the lift by sliding, plugging and twisting when in use, on the one hand, since the portable electric power construction lift with the above structure needs to slide the sliding hoop and continuously pull the pull ring when adjusting the height to avoid obstruction caused by the telescopic part of the plug-in lift, the above adjustment method requires multiple people to work together to complete the adjustment of the slide height, resulting in the electric power construction lift with the above structure being unable to be quickly adjusted and used when maintenance personnel are short. On the other hand, the portable electric power construction lift with the above structure is mainly used when not in use. The problem is that the electric power construction lift is carried by hand, which consumes a lot of manpower when carrying. When in use, the utility model can realize the rotation of the transmission rod by manually turning the hand wheel in the adjustment assembly by one person, so that the screw rod can be rotated under the action of gear one and gear two while the transmission rod is rotating, so that the inner ladder frame can be quickly extended relative to the outer ladder frame through the cooperation of the screw rod and the screw groove, which is convenient for the rapid adjustment and use of the electric power construction ladder when there is a shortage of maintenance personnel. On the other hand, under the action of the sliding assembly, the electric power construction ladder can be slid and carried with the help of the pulley in the sliding assembly when not in use, which effectively reduces the manpower consumption of the slide during the carrying process.

After the wheel 401 rotates, the inner ladder frame 1 can be conveniently lifted and moved along the outer ladder frame 2 under the action of the threaded transmission. Two sliding components 3 are symmetrically installed on both sides of the bottom end of the outer ladder frame 2. The sliding component 3 includes a U-shaped block 303 installed at the bottom end of the outer ladder frame 2, a pulley 304 installed in the concave part of the U-shaped block 303, a clamping block 302 symmetrically installed on one side wall of the U-shaped block 303, and a fixing groove 301 provided on the outer ladder frame 2 and cooperating with the clamping block 302. After the U-shaped block 303 rotates to the bottom end of the outer ladder frame 2, the outer ladder frame 2 is tilted to achieve the interference limit of the U-shaped block 303 at the bottom end of the outer ladder frame 2, thereby ensuring that the outer ladder frame 2 can be conveniently moved in an inclined sliding manner.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, a storage groove 5 is opened in the outer ladder frame 2 at the inner ladder frame 1, and the storage groove 5 is slidably connected to the inner ladder frame 1. The storage groove 5 can ensure the convenient sliding and storage of the inner ladder frame 1 in the outer ladder frame 2. The transmission rod 406 is rotatably connected to the outer ladder frame 2. The end of the transmission rod 406 extends out of the outer ladder frame 2 and is welded to the hand wheel 401. Rotating the hand wheel 401 can realize the convenient rotation of the transmission rod 406. Gear 1 405 is welded to the transmission rod 406, and gear 1 405 is meshed with gear 2 404. After the gear 1 405 rotates under the action of the transmission rod 406, it will drive gear 2 404 to rotate, so as to realize the rotation of the screw rod 403.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the screw rod 403 is rotatably connected to the outer ladder frame 2, the screw rod 403 is welded to the gear 2 404 and the screw rod 403 is located in the storage groove 5, the screw rod 403 is screwed to the screw groove 402, and the size of the screw groove 402 matches the size of the screw rod 403, which can ensure that the screw rod 403 and the screw groove 402 are reliably matched and installed.

[0035] The specific implementation process of this embodiment is as follows: when in use, the electric construction ladder is first moved to the construction position in an inclined manner with the help of the sliding assembly 3, and then the sliding assembly 3 is clamped on the outer ladder frame 2, and the transmission rod 406 is rotated by turning the hand wheel 401. After the transmission rod 406 rotates, it will drive the gear 2 404 to rotate under the action of the gear 1 405. After the gear 2 404 rotates, it will drive the screw rod 403 to rotate. After the screw rod 403 rotates, the inner ladder frame 1 will be extended along the outer ladder frame 2 under the action of the threaded transmission. After the inner ladder frame 1 is extended to a specified length, it is only necessary to lean the outer ladder frame 2 and the inner ladder frame 1 against the corresponding building wall to put the electric construction ladder into use. Because when in use, the electric construction ladder can not only realize the rotation of the transmission rod 406 by manually turning the hand wheel 401 in the adjustment component 4 by one person, so that the screw rod 403 can be rotated under the action of gear one 405 and gear two 404 while the transmission rod 406 rotates, so that the inner ladder frame 1 can be quickly extended relative to the outer ladder frame 2 through the cooperation of the screw rod 403 and the screw groove 402, which is convenient for the rapid adjustment and use of the electric construction ladder when there is a shortage of maintenance personnel. At the same time, under the action of the sliding component 3, the electric construction ladder can be slid and carried with the help of the pulley 304 in the sliding component 3 when not in use, effectively reducing the manpower consumption of the slide during the carrying process.
