Problems solved by technology

At a height of more than 50 meters or higher, there are serious safety hazards for the staff who need to climb the tower crane to work
Users need to buckle one section at a time. When working in a hurry, in order to save time, many users will ignore the wearing of the safety sling. Tragedy often happens at this time, and the safety of the safety sling is not completely reliable.

Embodiment Construction

[0018] Such as Figure 1-3 A standard section ladder is shown, including a climbing cage 1, a steel plate a2, a steel plate b3, a pedal 4 and a spring cross hinge butterfly hinge 5;

[0019] The steel plate a2 and the steel plate b3 are fixed on the spring cross hinge butterfly hinge 5, and are connected with the climbing cage 1 through the spring cross hinge butterfly hinge 5;

[0020] The upper and lower ends of the steel plate a2 are respectively provided with a pedal 4, and the pedal 4 is provided with a tripod 6;

[0021] The pedal 4 at the lower end of the steel plate a2 is provided with an infrared monitoring device;

[0022] Through infrared sensing of body temperature, the steel plate b3 can be flipped 270° from the outside of the ladder to the inside.

[0023] The preferred solution of the standard section ladder is that both the steel plate a and the steel plate b are provided with soft packages. Statement security for better protection of people.

[0024] The s...

Abstract

The invention discloses a standard section crawling ladder. The standard section crawling ladder comprises a crawling cage, steel plates a, steel plates b, pedals and spring cross butterfly hinges, wherein each steel plate a and each steel plate b are fixed on the corresponding spring cross butterfly hinge and are connected with the climbing cage through the spring cross butterfly hinge; the pedals are arranged at the upper end and the lower end of each steel plate a respectively, and tripods are arranged on the pedals; infrared monitoring devices are arranged on the petal at the lower ends ofthe steel plates a; and through infrared induction of body temperatures, the steel plates b can be turned by 270 degrees from the outside to the inside of the crawling ladder. The standard section crawling ladder is higher in safety, more convenient to operate, simple and convenient to mount, high in humanization degree and low in relative cost.

Description

technical field [0001] The invention relates to the technical field of climbing ladders, and in particular relates to a standard section climbing ladder. Background technique [0002] The tower crane is generally at a height of more than 50 meters. The users and maintainers of the tower crane must climb the ladder to go up and operate, and the ladder operation (operation, maintenance, testing) is from middle-aged people who have worked for many years, down to fledgling college students, Homework for all ages. At a height of more than 50 meters or higher, there is a serious safety hazard for the staff who need to climb the tower crane to work. For tower crane users, most of the existing safety equipment in the process of working at heights is to install a sling on the tower crane, one end is hung in the climbing cage suspended in the middle of the standard, and the other end is connected to the connecting rope of the operator's body end. Users need to buckle one section at...
