[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see the appendix Figure 1-5 This application provides the following technical solutions.

[0022] A steel structure for a crane ladder with a safety protection structure includes two fixed rods 1. A safety railing 2 is fixedly connected to one side of each fixed rod 1. Several anti-slip climbing rods 3 are fixedly connected to opposite sides of the two fixed rods 1. A fixed slide rail 4 is fixedly connected to the middle of each anti-slip climbing rod 3. The fixed slide rail 4 includes a slide rail body 41. A limit groove 42 is formed through the top of the slide rail body 41. A safety rope fixing component 6 is slidably connected to the inner wall of the limit groove 42. Several locking components 5 are fixedly connected to both sides of the slide rail body 41. The locking components 5 and the anti-slip climbing rods 3 are alternately arranged vertically. The locking assembly 5 includes two limiting climbing rods 51. The outer walls of the two limiting climbing rods 51 are slidably connected to movable sleeves 53. The outer walls of the two movable sleeves 53 are provided with anti-slip textures. A connecting rod 57 is fixedly connected to one side of the two movable sleeves 53. Limiting holes 43 are provided in the limiting groove 42 near the limiting climbing rods 51. A sliding groove 52 is provided through the top and bottom of one of the limiting climbing rods 51 near the slide rail body 41. A blocking block 54 is slidably connected to the inner wall of the sliding groove 52. The upper and lower ends of the blocking block 54 pass through the sliding groove 52 and are fixedly connected to the movable sleeve 53.

[0023] It should be noted that during use, if a worker falls due to operational error, the sliding block 61 will slide down along the limiting groove 42 and be blocked by the blocking block 54, stopping the worker from falling and reducing the injury. When the worker is climbing down, the sliding block 61 slides along the limiting groove 42 and stops at the top of the blocking block 54. At this time, the worker holds the corresponding sliding groove 52 and slides it horizontally. The connection of the connecting rod 57 causes the two movable sleeves 53 to move together, driving the blocking block 54 to detach from the slide rail body 41, allowing the safety rope fixing piece 6 to continue sliding down, so that the worker's climbing hand can open the blocking block 54 no matter which side it is on.

[0024] One end of the blocking block 54 is inserted through the limiting hole 43. The bottom surface of the blocking block 54 located in the limiting groove 42 is provided with an inclined surface. The end of the blocking block 54 away from the fixed slide rail 4 is fixedly connected to a sliding rod 55. The end of the sliding rod 55 away from the blocking block 54 is fixedly connected to a spring 56 through an anti-detachment block. The end of the spring 56 away from the sliding rod 55 is fixedly connected to the limiting climbing rod 51 through a fixing block. The safety rope fixing component 6 includes a sliding block 61. Several rollers 63 are rotatably connected to the side wall of the sliding block 61. The rollers 63 are in movable contact with the inner wall of the limiting groove 42. A connecting block 64 is fixedly connected to one side of the sliding block 61. A retaining ring 65 is rotatably connected to one end of the connecting block 64. A slope 62 is provided on the top of the sliding block 61. The top of the slope 62 is corresponding to the inclined surface at the bottom of the blocking block 54.

[0025] It should be noted that after the staff puts on the safety harness securely and confirms that it is intact, they fasten the harness connection into the snap ring 65. Then, they start climbing the device through the fixed rod 1 and the anti-slip climbing rod 3. The connecting block 64 drives the sliding block 61 to move along the slide rail body 41. The roller 63 rolls on the inner wall of the limiting groove 42 to reduce friction. The anti-slip climbing rod 3 increases the safety of the device. When the slope 62 set at the top of the sliding block 61 comes into contact with the inclined surface at the bottom of the blocking block 54, the sliding block 61 pushes the blocking block 54 through the limiting hole 43 and slides along the inner wall of the sliding groove 52, causing the blocking block 54 to move. This causes the spring 56 to contract and generate elastic potential energy until the blocking block 54 disengages from the slide rail body 41. The safety rope fixing piece 6 moves upward along the limiting groove 42 again and passes through the locking assembly 5. The spring 56 releases its elastic potential energy and pushes the blocking block 54 back to its original position.

[0026] In use, the operator first securely puts on the safety harness and, after confirming its integrity, fastens the harness connection into the shackle 65. Then, using the fixed rod 1 and anti-slip climbing rod 3, the operator begins climbing the device. The connecting block 64 drives the sliding block 61 to move along the slide rail body 41. The roller 63 rolls on the inner wall of the limiting groove 42 to reduce friction. The anti-slip climbing rod 3 increases the device's safety. When the slope 62 at the top of the sliding block 61 contacts the inclined surface at the bottom of the blocking block 54, the sliding block 61 pushes the blocking block 54 through the limiting hole 43 and slides along the inner wall of the sliding groove 52, causing the blocking block 54 to move. This causes the spring 56 to contract, generating elastic potential energy until the blocking block 54 detaches from the slide rail body 41. The safety rope fixing member 6 then moves along the... As the limiting groove 42 moves upward again through the locking assembly 5, the spring 56 releases its elastic potential energy to push the blocking block 54 back to its original position. When the worker falls due to operational error, the sliding block 61 slides downward along the limiting groove 42 and is blocked by the blocking block 54, stopping the worker from falling and reducing the injury. When the worker climbs down, the sliding block 61 slides along the limiting groove 42 and stops at the top of the blocking block 54. At this time, the worker holds the corresponding sliding groove 52 and slides horizontally. The connection of the connecting rod 57 causes the two movable sleeves 53 to move together, driving the blocking block 54 to disengage from the slide rail body 41, allowing the safety rope fixing piece 6 to continue sliding downward, so that the worker's climbing hand can open the blocking block 54 no matter which side it is on.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
