The invention relates to a simple manhole cover quick opening and carrying device which comprises a supporting structure, wherein the supporting structure comprises a vehicle frame, the vehicle frame is of a horizontally-arranged U-shaped rod structure with a forward opening, a handrail inclining upwards is fixedly arranged at the rear end of the vehicle frame, and the two sides of the vehicle frame are each provided with a wheel; and a grabbing structure which comprises a rotating rod, wherein two clamping jaws used for grabbing the manhole cover are movably arranged at the bottom of the rotating rod, an operating handle is arranged on a grabbing part at the top of the handrail, and the operating handle is connected with the clamping jaws through a steel wire rope transmission mechanism. The clamping jaw structure capable of rotating relative to the frame is adopted, so that the manhole cover is always kept in a horizontal free state when lifted and opened, the manhole cover cannot incline along with the angle change of the frame, shearing force cannot be generated on the clamping jaws, and the service life of the clamping jaws is prolonged; and under the condition that shearing force is not generated on the clamping jaws, the frame can be tilted by a larger height during transportation, so that the labor intensity of operators is reduced, and the trafficability of the device is improved.
本发明是一种简易井盖快速开启及搬运装置,包括:支撑结构,支撑结构包括车架,车架为水平设置、开口向前的U形杆结构,车架后端固设有向上倾斜的扶手,车架两侧各设有一个车轮;抓取结构,抓取结构包括转动杆,转动杆底部活动设有两个用于抓取井盖的夹爪,扶手顶部抓握部设有操作柄,操作柄通过钢丝绳传动机构与夹爪相连。本发明采用可与车架相对转动的夹爪结构,使得井盖在提升开启时始终保持水平的自由状态,而不会随车架的角度变化而发生倾斜,从而不会对夹爪产生剪切力,延长了夹爪寿命;在不对夹爪产生剪切力的情况下,运输时车架可翘起更大的高度,不仅减少了操作人员的劳动强度,而且增加了装置的通过性。
