Problems solved by technology

[0003] However, the crane hoisting operation space of the power grid plant (station) is small, and it faces the risk of electric shock caused by accidental contact with high-voltage live equipment, and the existing crane hoisting telescopic arm does not consider the safe distance detection function of the high-voltage power grid in the structural design. If the temporary installation is safe Distance detection equipment is time-consuming and labor-intensive

Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 to Figure 5 As shown, in the embodiment of the present invention, a crane hoisting telescopic arm is proposed, which is arranged between the crane base (not shown) and the crane head (not shown), including the main arm L1 and its inner parts in sequence one by one. The telescopic multi-section jib L2 also includes a telescopic hydraulic strut and a telescopic mechanism; wherein, the main arm L1 is fixed on the crane base, and the above-mentioned multi-section jib L2 is embedded in it; the multi-section jib L2 is the most The outermost jib is embedded in the cavity of the main boom L1 and can realize telescopic movement in the cavity of the main boom L1. The innermost jib of the multi-section jib L2 is installed on the end away from the cra...

Abstract

The invention provides a crane hoisting telescopic arm which is arranged between a crane base and a crane head and comprises a main arm and a plurality of sections of auxiliary arms which are sequentially telescopic section by section in the main arm, wherein at least one safety distance measurement early warning device used for detecting surrounding obstacles is installed on the outer wall of the section of fly jib on the innermost layer, and each safety distance measurement early warning device can be contained in a corresponding sliding groove formed in the section of fly jib adjacent to the section of fly jib on the innermost layer; each sliding groove is a notch groove located in the inner wall of the adjacent section of the section of the auxiliary arm on the innermost layer, and each notch groove is a long-strip-shaped groove with a notch. Each safe distance measurement early warning device can move back and forth in the corresponding sliding groove, the set alarm upper limit value of the safe distance measurement early warning device is smaller than or equal to the preset detection range of the safe distance measurement early warning device, and the set alarm lower limit value is larger than the radial value of the corresponding sliding groove. According to the invention, detection and early warning can be carried out on obstacles in a safe area during the hoisting operation of the crane, the risk of touching electricity by mistake is reduced, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane hoisting telescopic arm. Background technique [0002] With the development of society, the probability of crane hoisting operation also increases, especially in power grid plants (stations). [0003] However, the crane hoisting operation space of power grid plants (stations) is small and faces the risk of accidental electric shock by high-voltage live equipment, and the existing crane hoisting telescopic arms do not consider the safety distance detection function of high-voltage power grid on-site operation in the structural design. If the temporary installation is safe Distance detection equipment is time-consuming and labor-intensive. [0004] Therefore, it is necessary to improve the existing crane hoisting telescopic arm, which can not only detect and warn the obstacles in the safe area during the crane hoisting operation, reduce the risk of accidental electric shock...
