Problems solved by technology

[0004] The safety ladder cages used in engineering are all directly installed and fixed on the ground, so that the height of the safety ladder cage cannot be adjusted. In addition, based on the use of flat-plate structure pedals in the safety ladder cage, there are gaps between adjacent pedals, so that construction workers can go up and down safely. It is easy to have a sense of fear in the ladder cage, and it will cause dizziness and cause safety accidents if it is serious

Embodiment 1

[0052] as attached figure 1 As shown, the present invention provides a height-adjustable safety ladder cage combination device for engineering, the structure of which includes a fixedly connected safety ladder cage and a height-adjustable component A.

[0053] The safety ladder cage also includes:

[0054] A ladder cage frame formed by a plurality of vertically arranged columns C and a plurality of horizontally arranged beams D is fixedly connected,

[0055]A plurality of safety ladders E arranged inside the cage frame. The safety ladder E is a closed staircase structure formed by connecting the first positions of multiple L-shaped pedals in sequence.

[0056] combined with figure 2 , the height-adjustable component A further includes:

[0057] Vertically arranged adjusting lead screw A9;

[0058] The fixed base A6 is sleeved on the outer side of the lower part of the adjustment screw A9, the adjustment screw A9 is connected to the fixed base A6 through the upper bearing ...

Embodiment 2

[0073] combined with Figure 7 , on the basis of the structure of Embodiment 1, a handle A4 is also fixed in the middle of the adjustment screw A9 involved, and the handle A4 is located below the lock nut A3. By turning the handle A4, the adjustment screw A9 is directly driven to rotate, which is convenient to use.

[0074] The T-shaped outer surface of the involved movable top seat A1 is arranged with a plurality of upper reinforcing ribs A2, which are used to improve the strength of the movable top seat A1 supporting the ladder cage frame upwards, and the outer surface of the fixed base A6 is arranged with a plurality of lower reinforcing ribs A2' is used to strengthen the self-strength of the fixed base A6.

Embodiment 3

[0076] combined with figure 1 , the safety ladder cage involved also includes a stair guard rail F, and the stair guard rail F is arranged on the upper surface of the safety ladder E.

[0077] The involved safety ladder cage also includes a protective net G, which is arranged on opposite sides of the safety ladder E, and the protective net G is in contact with the side of the safety ladder E.

[0078] combined with Figure 6 , in the three embodiments of the present invention, the height-adjustable component A involved is connected with the frame of the ladder cage through the center limit component B of the column, and the adjusting screw A9 extends upward into the limit square tube B1, and by rotating Tighten the bolt B6, adjust the telescopic length of the spring B7, so that the spherical limit head B5 presses against the outer surface of the adjustment screw A9 along the direction of the through hole B2, and under the action of multiple spherical limit heads B5, ensure th...

Abstract

The invention belonging to the technical field of safety ladder cages provides a height-adjustable safety ladder cage composite device for engineering. The height-adjustable safety ladder cage composite device comprises a safety ladder cage and a height adjusting assembly that are fixed connected. The safety ladder cage includes a ladder cage frame encircled by a plurality of standing columns anda cross beam based on fixed connection and a plurality of safety ladders arranged in the ladder cage frame. Besides, the height adjusting assembly includes a vertically arranged adjusting lead screw,a fixed base sleeving the lower part of the adjusting lead screw, a locking nut in threaded connection with the middle part of the adjusting lead screw, a moving top base having a T-shaped vertical cross section; the adjusting lead screw is connected with the fixed base by a bearing; a threaded hole is formed in the T-shaped middle part of the moving top base and the moving top base is connected to the bottom of the ladder cage frame fixedly and upwardly; the moving top base is in threaded connection with the upper part of the adjusting lead screw through the threaded hole; and when the adjusting lead screw rotates around the own axis, the moving top base moves up and down along the adjusting lead screw. Therefore, the height adjustment of the safety ladder cage is realized on the premisethat the verticality and the levelness of the safety ladder cage are ensured.

Description

technical field [0001] The invention relates to the technical field of safety ladder cages, in particular to a height-adjustable safety ladder cage combination device for engineering. Background technique [0002] During the construction of high bridge piers, deep foundation pits, subways and other constructions, safety ladder cages are usually provided to the staff for use. [0003] The structure of the safety ladder cage usually includes a ladder cage frame and a plurality of safety ladders arranged inside the ladder cage frame, wherein the ladder cage frame is fixedly connected by a plurality of columns and beams, and the plurality of safety ladders are arranged obliquely and connected end to end. [0004] The safety ladder cages used in engineering are all directly installed and fixed on the ground, so that the height of the safety ladder cage cannot be adjusted. In addition, based on the use of flat-plate structure pedals in the safety ladder cage, there are gaps betwee...
