[0002] With the construction of super-high-rise buildings, bridges, and large-capacity power plants, the material handling equipment used, namely tower cranes, is being installed at ever-higher heights. Especially with the rapid development of China's infrastructure and bridge construction, tower crane installations are reaching heights of 200m, 300m, and even 400m. This significantly increases the height and intensity of the climb required for operators to reach the driver's cab, increasing climbing time from under 20 minutes to 1-2 hours, impacting construction progress. Vertical climbing also consumes significant physical energy, leading to fatigue and reduced work efficiency, indirectly increasing construction safety risks.

[0003] Existing technologies, such as the patent with announcement number "CN 209405607 U", disclose a convenient and stable electric tower climbing device, which uses a threaded connection method to connect the climbing rod to the corresponding regular hexagonal prism connecting shaft and the connecting threaded hole of the regular hexagonal prism mounting shaft, and climbs upward through multiple climbing rods. The above existing technologies have achieved the effect of providing convenient climbing, but when used on a tower crane that is too high, the operators need to climb upward manually and need to install the climbing rods in advance, which consumes a lot of time in the climbing process, reduces work efficiency and increases construction safety hazards. Utility Model Content

[0006] Working principle of the utility model: When operation is required, the vehicle body is located at the bottom of the ladder under the drive of the guide rail assembly. The staff stands on the vehicle body and connects the safety rope to the anti-fall device. At this time, the guide rail assembly is started, and the guide rail assembly drives the vehicle body to rise on the ladder. When the vehicle body reaches the operation height, the guide rail assembly is stopped. At this time, the drive assembly is started, and the drive assembly makes the pressing block inside the vehicle body press tightly against the guide rail assembly. At this time, the vehicle body is fixed on the ladder, and the staff can start working.

The upper limit trigger and the lower limit trigger are electrically connected to the motor. When working, the motor is started, and the output shaft of the motor drives the multiple guide wheels to rotate, so that the multiple guide wheels move on the rack guide rail, driving the vehicle body to rise or fall.

[0009] Further, the drive assembly includes a punch rod and a hydraulic cylinder. The punch rod is connected to the side of the vehicle body, the hydraulic cylinder is connected to the inside of the vehicle body, the output shaft of the hydraulic cylinder is horizontally connected to the rack guide rail and the pressing block, and the punch rod is electrically connected to the hydraulic cylinder. When working, the punch rod moves downward. At this time, the hydraulic cylinder is started, and the output shaft of the hydraulic cylinder drives the pressing block to extend outwards. The pressing block clamps the rack guide rail. When the operation is completed, the punch rod is lifted. At this time, the hydraulic cylinder is started, and the output shaft of the hydraulic cylinder drives the pressing block to press tightly against the vehicle body.

[0010] Further, a plurality of handles are connected to the top end of the vehicle body, and a pedal is arranged at the bottom end of the vehicle body. Through the arrangement of the pedal, the staff can stand better.

The output shaft of the motor drives the two guide wheels 10 to rotate, so that the two guide wheels 10 move on the rack guide rail 3, driving the vehicle body 6 to rise. When the vehicle body 6 reaches the working height, the motor is stopped. The punching rod 1103 is moved downward. At this time, the hydraulic cylinder 1102 is started. The output shaft of the hydraulic cylinder 1102 drives the pressing block 1104 to extend outwards. The pressing block 1104 clamps the rack guide rail 3. At this time, the vehicle body 6 is fixed on the climbing ladder 9 and the staff can start working. After the work is completed, the punching rod 1103 is lifted. At this time, the hydraulic cylinder 1102 is started. The output shaft of the hydraulic cylinder 1102 drives the pressing block 1104 to be close to the vehicle body 6. The motor is started. The output shaft of the motor drives the two guide wheels 10 to rotate in the reverse direction, so that the vehicle body 6 moves downward on the rack guide rail 3. When it moves to the initial position, the lower limit trigger 7 sends an electrical signal and the motor stops working. If the vehicle body 6 rises to the limited height, the upper limit trigger 1 contacts the vehicle body 6 and sends an electrical signal, and the motor stops working.
