[0023] See also Figure 4The first limit stop 355 of the present invention is a plurality of limit stops 351, 352 and 353. The limit stop 355 of the present invention is a plurality of limit stops 351, 352 and 353. The limit stop 355 of the present invention is a plurality of limit stops 351, 352 and 353. The limit stop 355 of the present invention is a plurality of limit stops 351, 352 and 353. The limit stop 355 of the present invention is a plurality of limit stops 351, 352 and 353.

[0024] See also Figure 5 The utility model provides a construction climbing frame, the pushing structure 37 includes a guide groove 371, a connecting rod 372, a push plate 373, an anchor point 374, an L-shaped plate 375, a sliding groove 376 and a positioning rod 377. The lower side of the inner wall of the guide groove 371 is in contact with the connecting rod 372, the rear end of the connecting rod 372 is fixedly connected to the limit plate 353, the lower end surface of the front side of the connecting rod 372 is in contact with the push plate 373, and the lower side of the push plate 373 is provided with an anchor point 374, and the anchor point 374 is fixed. An L-shaped plate 375 is installed in the middle of the front end surface of the sliding block 34 and the upper end surface of the push plate 373. A sliding groove 376 is opened in the middle of the front end surface of the L-shaped plate 375. The upper side of the inner wall of the sliding groove 376 is fitted with the positioning rod 377. The positioning rod 377 is fixedly connected to the sliding block 34. The guide groove 371 is opened on the front end surface of the sliding block 34. The front side diameter of the positioning rod 377 is larger than the width of the sliding groove 376, which is convenient for horizontally limiting the L-shaped plate 375 by the positioning rod 377.

[0025] Here's how it works:

[0026] First, the new climbing frame 1 is set at the desired location;

[0027] When the user wears the safety belt and hangs the safety belt hook on the anchor point 374 for support and limitation, when the user climbs up the ladder, the safety belt hook pulls the sliding block 34 to move upward along the straight rod 33. The limiting block 355 of the first limiting structure 35 of the sliding block 34 is consistent with the inclined angle of the latch tooth 32. When the limiting block 355 moves upward, it is squeezed by the latch tooth 32, so that the limiting block 355 slides along the limiting rod 352 through the slot 356, and the limiting block 355 drives the limiting plate 353 to move. The limiting plate 353 squeezes the spring 354, causing the spring 354 to contract. At the same time, the second limiting structure 36 moves according to the same principle. After the limiting block 355 moves upward, it automatically extends out by utilizing the resilience of the spring 354. When the user accidentally falls, the latch tooth 32 supports the limiting block 355, preventing the sliding block 34 from sliding downward, thereby achieving the effect of protecting the user.

[0028] Third, the user pushes the L-shaped plate 375 upward, and the L-shaped plate 375 drives the push plate 373 to move upward. The push plate 373 pushes the two sets of connecting rods 372 to move upward. The connecting rods 372 use the limit of the guide groove 371 to drive the two sets of limit blocks 355 to retract, thereby releasing the limit on the sliding block 34, making it easier for the user to move downward.

[0029] The control method of the present invention is to manually start and stop the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices. Therefore, the control method and wiring arrangement are not explained in detail in the present invention.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
