Description

Technical Field

[0001] The invention relates to the field of building ladders, in particular to a safety folding ladder for construction engineering. Background Art

[0002] In building construction, in order to facilitate construction at high places, folding stairs are used in buildings for climbing to high construction positions. There is currently a public patent with a patent number of CN202122963369.0, which discloses a folding staircase for use at a construction site of a building project, including several groups of L-shaped support plates and a wall connection device for fixing each L-shaped support plate to a wall. Each wall connection device includes an articulated frame rotatably connected to the corresponding L-shaped support plate through a pin shaft and a clamping frame clamped to the corresponding L-shaped support plate. The L-shaped support plate includes a pedal, a support frame, a material transport plate and a clamping block. The pedal is fixedly connected to the support frame, and the clamping block is fixed above the side of the pedal away from the wall. The pedal is rotatably connected to the material transport plate through a rotating shaft. Rollers are installed on both sides of the material transport plate. When in the unfolded state, the clamping frame is separated from the clamping block, and the L-shaped support plate rotates around the articulated frame until the pedal is in a horizontal state. The material transport plate is rotated and tilted through the rotating shaft, and a conveyor belt is installed to the roller. People step on the pedal to assist in transporting materials on the conveyor belt.

[0003] However, in this disclosed patent, there is no protective mechanism on the side of the pedal away from the wall. As the position of the pedal gradually increases, if an accidental collision or slip occurs during walking, the worker may fall from a height, and the safety of using the stairs is low.

The shock-absorbing spring 16 at the lower part of the upper support column 14 is arranged on the inner side of the lower support column 15, and the bottom end of the lower support column 15 is fixedly connected to a base 17 connected to the ground with bolts, and both sides of the bottom end of the top plate 9 are fixedly connected to the side support columns 10, and the bottom ends of the side support columns 10 are fixedly connected to the support plate 11, and the bottom ends of both sides of the support plate 11 are hinged to the shock-absorbing structure 12, and the bottom end of the shock-absorbing structure 12 is fixedly connected to the base 13 connected with bolts.

[0025] The shock-absorbing bolt structure 2 includes: a support tube 2.1 fixedly connected to the bottom end of the base plate 1, a shock-absorbing spring 2.2 fixedly connected to the top end of the support tube 2.1, a T-bolt 2.3 fixedly connected to the ground at the bottom end of the shock-absorbing spring 2.2, and a top end of the shock-absorbing spring 2.2 fixedly connected to the bottom end of the base plate 1.

The shock-absorbing mechanism under the top plate also has a shock-absorbing and buffering effect, which reduces the noise caused by stepping on the top plate, improves the supporting strength, and increases the safety index.

[0030] During use of the device, the bottom ends of both sides of the base plate 1 are fixedly connected to the ground through the shock-absorbing bolt structure 2. The shock-absorbing spring 2.2 increases the comfort of the foot pedal base plate 1 and reduces shock. It is not easy to make noise when stepping on it. The upper side of the horizontal pedal 5 is fixedly connected to the non-falling structure 6 by bolts. When it hits the side railing 7, the middle part of the supporting ball 6.2 in the non-falling structure is hinged to the inner bottom end of the hemispherical package 6.1 through the support rod 6.3, thereby reducing the probability of the side railing 7 toppling over and improving the safety index. A shock-absorbing spring 2 16 is provided at the lower middle part of the inclined support plate 4. Due to the shock-absorbing and buffering effect, the noise of stepping on the horizontal pedal is reduced, the supporting strength is improved, and the stability is increased. The shock-absorbing mechanism under the top plate also has a shock-absorbing and buffering effect, which reduces the noise of stepping on the top plate, improves the supporting strength, and increases the safety index.
