[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, a safety ladder for construction includes a moving unit 1, a climbing unit 2 arranged above the moving unit 1, an extension unit 3 arranged inside the climbing unit 2, and an adjustment unit 4 arranged between the moving unit 1 and the climbing unit 2;

[0031] like Figure 5 As shown, the extension unit 3 includes a movable frame 301 movably mounted on the inner wall of the climbing unit 2, a reinforcing plate 302 mounted on the inner wall of the movable frame 301, and a connecting member 303 arranged between the movable frame 301 and the reinforcing plate 302. The connecting member 303 is arranged to achieve a stable connection between the movable frame 301 and the reinforcing plate 302;

[0032] like Figure 2As shown in the figure, the adjusting unit 4 includes a U-shaped seat 401 installed at the bottom of the climbing unit 2, a fixed column 402 installed inside the U-shaped seat 401, a moving member 403 movably installed on the circumferential side of the fixed column 402, and a telescopic member 404 arranged above the moving unit 1. During the telescopic process of the telescopic member 404, the moving member 403 can be driven to slide along the fixed column 402.

[0033] As Figure 1 shown in the figure, the moving unit 1 includes a base 101 and universal wheels 102 installed at the bottom of the base 101. The setting of the universal wheels 102 facilitates the movement of the safety ladder.

[0034] As Figure 1 shown in the figure, the moving unit 1 further includes a traveling handrail 103 installed at the top of the climbing unit 2. The setting of the traveling handrail 103 facilitates the control of the traveling direction.

[0035] As Figure 5 shown in the figure, the climbing unit 2 includes a climbing frame 201 movably installed inside the base 101 and a plurality of climbing boards 202 installed on the inner wall of the climbing frame 201. The plurality of climbing boards 202 are arranged at equal intervals, and the climbing boards 202 facilitate the staff to climb up.

[0036] As Figure 4 shown in the figure, the telescopic member 404 includes a U-shaped seat 4041 installed at the top of the base 101 and a hydraulic telescopic rod 4042 movably installed inside the U-shaped seat 4041 with its telescopic end movably connected to the moving member 403. During the telescopic process of the hydraulic telescopic rod 4042, the moving member 403 can be synchronously driven to move.

[0037] When it is necessary to adjust the pitching angle of the safety ladder, the telescopic end of the hydraulic telescopic rod 4042 expands and contracts. When the telescopic end of the hydraulic telescopic rod 4042 extends, the moving member 403 moves upward along the fixed column 402, and then drives the climbing frame 201 to rotate clockwise around the base 101. At this time, the included angle of the safety ladder becomes smaller and the overall height decreases. When the telescopic end of the hydraulic telescopic rod 4042 contracts, the moving member 403 moves downward along the fixed column 402, and then drives the climbing frame 201 to rotate clockwise around the base 101. At this time, the included angle of the safety ladder becomes larger and the overall height increases.

[0038] Embodiment 2

[0039] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown in the figure, a safety ladder for building construction includes a moving unit 1, and further includes a climbing unit 2 arranged above the moving unit 1, an extension unit 3 arranged inside the climbing unit 2, and an adjusting unit 4 arranged between the moving unit 1 and the climbing unit 2;

[0040] As shown Figure 5 in the figure, the lengthening unit 3 includes a movable frame 301 movably installed on the inner wall of the climbing unit 2, a reinforcing plate 302 installed on the inner side wall of the movable frame 301, and a connecting member 303 disposed between the movable frame 301 and the reinforcing plate 302. The setting of the connecting member 303 is used to achieve a firm connection between the movable frame 301 and the reinforcing plate 302;

During the telescopic process of the telescopic member 404, the moving member 403 can be driven to slide along the fixed column 402.

[0042] As shown Figure 1 in the figure, the moving unit 1 includes a base 101 and universal wheels 102 installed at the bottom of the base 101. The setting of the universal wheels 102 facilitates the movement of the safety ladder.

[0043] As shown Figure 1 in the figure, the moving unit 1 further includes a traveling handrail 103 installed at the top of the climbing unit 2. The setting of the traveling handrail 103 facilitates the control of the traveling direction.

[0044] As shown Figure 5 in the figure, the climbing unit 2 includes a climbing frame 201 movably installed in the base 101 and a plurality of climbing boards 202 installed on the inner wall of the climbing frame 201.

The setting of the connecting spring 3034 facilitates the automatic rebound of the clamping seat 3032.

[0046] As shown Figure 3 in the figure, the connecting member 303 further includes a clamping groove opened on the side wall of the movable frame 301. When the clamping seat 3032 is clamped with the clamping groove, the fixation between the movable frame 301 and the climbing frame 201 is achieved.

[0047] As shown Figure 4As shown, the telescopic member 404 includes a U-shaped seat 4041 installed on the top of the base 101, a hydraulic telescopic rod 4042 movably installed inside the U-shaped seat 4041 and with the telescopic end movably connected to the moving member 403. During the telescopic process of the hydraulic telescopic rod 4042, the moving member 403 can be synchronously driven to move.

[0048] When it is necessary to extend the overall height of the safety ladder for construction, first, pull the stretching seat 3033 so that the movable column 3031 drives the locking seat 3032 to approach the climbing frame 201 and compress the connecting spring 3034. Then, rotate the movable frame 301 clockwise until the movable frame 301 touches the climbing frame 201 and stops. At this time, remove the force applied to the stretching seat 3033, and under the elastic force of the connecting spring 3034, the locking seat 3032 is locked with the locking groove; thereby achieving the height extension of the safety ladder.
