Problems solved by technology

[0009] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent foldable crane for municipal roads, so as to solve the problem of low intelligence and complex working environment in the prior art during the construction of municipal roads. Folding cranes cannot effectively solve the deficiencies in the operation process, and it is easy to cause the equipment to pull and rush to the top. The safety performance is too low, and it cannot effectively maintain the safety of the equipment and the efficiency of municipal road construction.

Abstract

The invention discloses an intelligent foldable crane for a municipal administration path. The intelligent foldable crane structurally comprises a fixing base, an execution mechanism, a coupling rod, a cargo boom support rod, a pin shaft, a hydraulic cylinder, a folding arm, a main arm, a hoisting folding hydraulic cylinder, bolts, an end wall connecting shaft, an end wall, a cushion plate, a drive rotary disc, a telescopic square pipe, a hook and a hydraulic cylinder fixing base. In the crane folding process, an oblique pulling sensor and a jacking sensor are arranged in the execution mechanism, and accordingly the system works more reliably; in combination of the design of a single-chip microcomputer and a programmable logic controller, the functions of voice broadcasting, communication management, monitoring and intelligent machine body control are achieved, the defect in the folding crane running process can be effectively overcome, the situations of equipment oblique pulling and jacking are avoided, safety performance is high, equipment safety is effectively maintained, and the municipal administration path construction efficiency is improved.

Description

technical field [0001] The invention is an intelligent foldable crane used for municipal roads, which belongs to the field of cranes. Background technique [0002] Urban roads are divided into four levels: expressway, main road, sub-arterial road, and branch road. The width of the red line at each level is controlled: the expressway is not less than 40 meters, the main road is 30-40 meters, the secondary road is 25-40 meters, and the branch road is 12-40 meters. 25 meters, there is no mandatory requirement for the width of the red line of the road, only the requirements for the width of the road, the composition of the cross section and the minimum width of each functional belt; [0003] ⑴ Expressway Urban roads are provided with a central divider, with more than four motor vehicle lanes, all or part of which adopt three-dimensional intersections and control access, and are used by vehicles to drive at relatively high speeds, also known as vehicle-only lanes. The designed d...
