Preferably, the buffer plates are two in total, and the buffer plates have the function of better buffering impact force.

Compared with the prior art, the beneficial effects of the utility model are that: through motor, slider, handrail, threaded rod, make the cat ladder have the activity handrail that can adjust at any time, control, make the workman also can not have the thing to hold up even the operation of standing, the effectual probability that has reduced the workman and accidentally drop because of the health is unbalanced through buffer board, spring, telescopic link, make the cat ladder can utilize buffer board and spring to absorb the impact in unexpected landing, and then reduce the injury to cat ladder and workman, increase the security of cat ladder.

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a top view of the present invention;

fig. 3 is a bottom view of the present invention.

In the figure: 1 ladder frame, 10 diaphragm, 11 springs, 12 buffer boards, 13 guide bars, 14 anti-skidding stripes, 15 ladder bars, 16 batteries, 17 grooves, 18 telescopic rods, 2 motors, 3 vertical boards, 4 sliding blocks, 5 handrails, 6 anti-skidding rubbers, 7 threaded rods, 8 infrared receivers and 9 round bars.

Detailed Description

Referring to fig. 1, 2 and 3, a ladder stand for hydraulic engineering overhaul comprises ladder stands 1, ladder rods 15 are welded between the ladder stands 1, vertical plates 3 are welded on the ladder stands 1, a motor 2 is connected on the vertical plates 3 through screws, the motor 2 is used for providing power for sliding blocks 4 to enable handrails 5 to be adjusted at any time, threaded rods 7 are rotatably connected between the vertical plates 3, guide rods 13 are welded between the vertical plates 3, a main shaft of the motor 2 penetrates through the vertical plates 3 to be connected with the threaded rods 7 through a coupler, the sliding blocks 4 are connected on the threaded rods 7 in a threaded matching manner, the sliding blocks 4 are rotatably connected with the guide rods 13, round rods 9 are welded on the ladder stands 1, a transverse plate 10 is welded at one end of each round rod 9, springs 11 are welded on the transverse plate 10, telescopic rods 18 are arranged on the transverse plate 10, grooves 17 are arranged on the buffer plates 12, the telescopic rods 18 are slidably connected with the grooves 17, and buffer plates 12 are welded at one end of the springs 11, the buffer plate 12 is used for absorbing the impact force by the buffer plate 12 and the spring 11 when the ladder stand accidentally slips off, so that the damage to the ladder stand and workers is reduced, and the safety of the ladder stand is improved.
