Embodiment Construction

[0029] The core of the invention is to provide a built-in boom full-shrink detection device. The device can effectively save the peripheral space of the arm frame and reduce the influence of the external environment, thereby improving the reliability and quality of the product.

[0030] Another core of the present invention is to provide a high-altitude operation construction machine provided with the detection device.

[0031] In this article, terms such as "front, back, left, right" indicating orientation are based on the positional relationship of the drawings, and should not be understood as an absolute limitation on the scope of protection. Similarly, terms such as "first, second" It is only for the convenience of description to distinguish different components with the same name, and does not indicate a sequence or a primary and secondary relationship.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the pr...

Abstract

The invention discloses a built-in cantilever frame fully-telescopic detecting device, which comprises a first detecting rod, a second detecting rod and a traveling switch. The traveling switch is mounted on a switch mounting board inside a second cantilever section, the front end of the first detecting rod is mounted on an oil cylinder base inside a fourth cantilever section movably laterally, the second detecting rod is mounted in a slide sleeve of the switch mounting board, a spring is arranged between the front end of the second detecting rod and the slide sleeve, the first detecting rod and the second detecting rod are arranged on the same axis, the rear end of the first detecting rod faces the front end of the second detecting rod, and a retaining board for triggering the traveling switch is arranged at the rear end of the second detecting rod. By the built-in cantilever frame fully-telescopic detecting device, the peripheral space of a cantilever frame can be effectively saved, affection from the external environment is reduced and accordingly reliability and quality of the built-in cantilever frame fully-telescopic detecting device are improved. The invention further discloses overhead operation engineering machinery which is provided with the built-in cantilever frame fully-telescopic detecting device.
