The portable crane capable of being assembled on the small car comprises a beam frame and a bottom block movably connected with the beam frame, the bottom of the bottom block is provided with a fixedly-installed arc-shaped petal and a hinged movable hook, a swing part is hinged to the end of the movable hook, ratchet teeth are fixedly installed on the swing part, and the ratchet teeth are movably connected with the arc-shaped petal. A clamping block for locking the ratchet teeth is hinged in the movable hook; the swing piece is attached to the arc-shaped petals in a default state; the movable hook swings upwards so that a preset distance can be kept between the swing piece and the arc-shaped petals. According to the portable crane capable of being assembled on the small car, the steel wire rope falls off from an opening between the swing part and the arc-shaped petal by overturning the movable hook, the movable hook swings upwards to the maximum angle, the clamping block swings to unlock ratchet teeth, the steel wire rope is pressed downwards on the swing part to enable the swing part to be overturned downwards, and therefore the steel wire rope can fall off conveniently; compared with manual picking of the steel wire rope, overturning of the stripping movable hook is more convenient, and the problem that workers are injured due to the fact that goods incline and collapse during manual stripping is solved.

    本发明公开了一种可装配于小型汽车的便携式起重机,包括梁架以及和梁架活动连接的底块,底块的底部设置有固定安装的弧形瓣以及铰接的活动钩,活动钩的端部铰接有摆件,摆件上固定安装有棘轮齿,活动钩内铰接有锁止棘轮齿的卡块;摆件在默认状态下贴合于弧形瓣上;活动钩上摆以使摆件和弧形瓣保持预定间距。该发明提供的可装配于小型汽车的便携式起重机,通过活动钩翻转使钢丝绳从摆件和弧形瓣之间的开口脱落,活动钩上摆至最大角度卡块摆动以对棘轮齿解锁,钢丝绳下压于摆件上以使摆件下翻,从而便于钢丝绳脱落,相比较人工摘取钢丝绳脱料活动钩的翻转更加便捷,且减少了因人工脱料时货物倾斜倒塌砸伤工人的问题。
