[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a telescopic ladder device for construction engineering, which has the following

[0018] Beneficial effects:

[0019] 1. The telescopic ladder device for construction engineering is provided with a driving mechanism and a moving mechanism. The driving mechanism makes the moving mechanism contact with the ground, and the telescopic ladder can be easily pushed to move by a push handle. When the telescopic ladder is not needed, the moving mechanism is driven to move downward. After the dual-axis servo motor is started, its left and right output shafts drive the threaded rod to rotate. Since the threaded rod is threadedly connected with the threaded block, the rotation of the threaded rod is converted into linear motion of the threaded block. The linear motion of the threaded block makes the strip plate move downward through the connecting plate and the U-shaped rod and is transmitted to the lifting plate, so that the lifting plate slides on the vertical rod, thereby driving the cylinder and the moving wheel to move downward, causing the moving wheel to contact with the ground, and then the telescopic ladder device can be pushed to move as a whole by the push handle, thereby achieving the purpose of easy moving.

[0020] 2. The telescopic ladder device for construction engineering is provided with a driving mechanism and a stabilizing mechanism. The driving mechanism drives the stabilizing mechanism to extend to improve the overall stability. The bottom of the threaded block drives the support plate to slide in the limit groove through the connecting column. When the ladder needs stable support during use, the support plate is extended and contacts the ground, and the moving wheels are retracted. The anti-slip pad at the bottom increases the friction to prevent the ladder from sliding, thereby achieving the purpose of anti-dumping function. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] There are four rectangular holes 9 in number and two are arranged in a group and are symmetrically distributed on the left and right sides.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] In summary, the telescopic ladder device for construction engineering is provided with a driving mechanism 3 and a moving mechanism 5. The driving mechanism 3 makes the moving mechanism 5 contact with the ground, and the push handle 11 is used to facilitate the movement of the telescopic ladder. When the telescopic ladder is not needed, the moving mechanism 5 is driven to move downward. After the dual-axis servo motor 31 is started, its left and right output shafts drive the threaded rod 32 to rotate. Since the threaded rod 32 is threadedly connected with the threaded block 33, the rotation of the threaded rod 32 is converted into a linear motion of the threaded block 33. The linear motion of the threaded block 33 causes the strip plate 53 to move downward through the connecting plate 54 and the U-shaped rod 55 and is transmitted to the lifting plate 52, so that the lifting plate 52 slides on the vertical rod 51, thereby driving the cylinder 56 and the moving wheel 57 to move downward, causing the moving wheel 57 to contact with the ground, and then the lifting plate 52 can be moved downward by the push handle 11. The telescopic ladder device is pushed to move as a whole, thereby achieving the purpose of easy moving. By setting a driving mechanism 3 and a stabilizing mechanism 4, the driving mechanism 3 drives the stabilizing mechanism 4 to extend to improve the overall stability. The bottom of the threaded block 33 drives the support plate 42 to slide in the limiting groove 10 through the connecting column 41. When the ladder needs stable support during use, the support plate 42 is extended and contacts the ground, and the moving wheel 57 is retracted. The anti-skid pad 43 at the bottom increases the friction to prevent the ladder from sliding, thereby achieving the purpose of having an anti-dumping function. The problem of being inconvenient to move the telescopic ladder and being able to move the telescopic ladder only by hand-held lifting is solved, which is time-consuming and laborious to use and carry, and does not have an anti-dumping function during use. The bottom of the telescopic ladder is prone to sliding, making the telescopic ladder unsafe when in use.
