A height measuring device includes a height measuring sleeve and a distance measuring mechanism. The height measuring sleeve is vertically disposed on the equipment to be measured and includes at least two sleeves which are sleeved and matched with each other. The distance measuring mechanism is provided at bottom or top of the height measuring sleeve. When the lifting mechanism drives the main body rise or fall, the height measuring sleeve extends or retracts as the main body or the lifting mechanism, so that a height information of the main body or the lifting mechanism is obtained according to a height information of the height measuring sleeve measured by the distance measuring mechanism.
