The invention relates to a portable assisting dismounting and transporting trolley for road metal guardrails, and belongs to the field of municipal engineering construction. The problems that time and labor are wasted and efficiency is low when metal guardrails used for roads, bridges and the like are disassembled and transferred are solved. The trolley has two functions of lifting and transporting. In order to disassemble the guardrail, a ratchet bar-pawl intermittent lifting mechanism is designed, and labor is saved under the driving of a lever mechanism. The trolley is mainly composed of an L-shaped bracket, an L-shaped connecting frame, a ratchet strip, a pawl, a pawl spring, a pawl rope, a T-shaped sliding block, a trapezoidal supporting frame, a rubber pad, a C-shaped groove, a rectangular-section lever, a U-shaped support, a circular-section rod, a U-shaped lever restraining frame, a pawl rope, a pawl rope penetrating pin, a lever rope penetrating pin, a handrail, a trolley plate and the like. The trolley is manually operated and has the advantages of simple structure, simplicity and convenience in operation, flexibility in operation, no pollution, low noise and the like. Meanwhile, the trolley is particularly suitable for the situation that a large number of metal guardrails are dismantled and transferred within a short time and used when the guardrails are installed.

    本发明涉及一种便携式道路金属护栏助力拆卸与运输小车,属于市政工程建设领域。解决了道路桥梁等使用的金属护栏拆卸与转运费时费力、效率低下等问题。小车包含举升和运输两个功能。为实现护栏拆卸,设计了棘条‑棘爪间歇举升机构,并在杠杆机构驱动下实现省力。该小车由L型托架、L型连接架、棘条、棘爪、棘爪弹簧、棘爪绳、T型滑块、梯形支撑架、橡胶垫、C型槽、矩形截面杠杆、U型支架、圆形截面杆杆、U型杠杆约束架、棘爪绳、棘爪穿绳销、杠杆穿绳销、扶手和车板等主要结构组成。小车为人工操作,具有结构简单、操作简便、运转灵活、无污染和低噪声等优点。同时,小车尤其适合短时间内拆除并转运大量金属护栏的情况,以及安装护栏时使用。
