Description

Technical Field

[0001] The present application is applied to the field of hoisting technology, and in particular relates to a hoisting device. Background Art

[0002] Major construction projects such as water conservancy, shipping, subways, and high-rise buildings often require the excavation of deep foundation pits or tunnels, which inevitably affect the slopes and surrounding buildings (structures). To ensure the safety of the slopes and surrounding buildings (structures), the regulations require regular deep water level monitoring of the slopes and surrounding buildings (structures). To this end, pressure measuring pipes need to be laid near the slopes and surrounding buildings (structures) within the affected area. During the installation process, it is necessary to drill a hole at the designed position first, and then install the pressure measuring pipe. Commonly used pressure measuring pipes are galvanized pressure measuring steel pipes with an inner diameter of 50mm and a thickness of 3.5mm. When a 6m long pressure measuring steel pipe is used, the weight of a single pipe is 30kg; and some pressure measuring holes are as deep as 60m, and 10 pipes connected together weigh 300kg. Therefore, in the process of lifting and installing the pressure measuring pipe, if a rope is used to fix it, it is easy to slip during the lifting process, causing the pressure measuring pipe to fall from the air. If it hits the installation workers below, it will cause serious production safety accidents; and in the case of a depth of 60m, the pressure measuring pipe weighs hundreds of kilograms, and multiple people are required to hold the installed pressure measuring pipe on site. If it is fixed by manpower alone, once it is lost in the middle, the installed part of the inclinometer pipe will fall into the borehole, which will cause the entire pressure measuring pipe to be scrapped, thereby causing economic losses.
