Installation device for transmission line screw pile and assembling method of installation device

Abstract

The invention provides an installation device for a transmission line screw pile and an assembling method of the installation device. A loader-digger is transformed, so that the loader-digger has the screw pile installation function. According to the specific scheme, a power output shaft of a hydraulic rotary power head is provided with a quick connecting piece used for being connected with a screw pile material and further provided with a torque displayer used for measuring and displaying the torque value reached by rotation of the screw pile in real time, and the torque displayer is installed on the power output shaft of the hydraulic rotary power head. Due to the low transforming price and the dual-purpose function, the installation device for the screw pile is no longer a bottleneck restraining popularization of a screw pile type foundation in a transmission line, and the simple, convenient and efficient foundation mode can be widely applied and popularized. In construction of an iron tower foundation of the transmission line, the installation device is used so that the construction efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of transmission line iron tower foundation construction, in particular to a screw pile installation device. Background technique [0002] Long-distance power transmission lines often cross a variety of geological forms. During the construction of power transmission lines, it is inevitable to encounter geological conditions such as sandy soil, swamps and shallow groundwater layers. These geological conditions have a great impact on the construction of transmission line tower foundations. In recent years, a new type of foundation construction—screw pile has emerged as the times require. This foundation form can effectively solve the foundation construction under these special geological conditions. [0003] Screw piles consist of two parts, the anchor head and the extension rod. The anchor head is rod-shaped, with a helical helical blade at the end. It is screwed into the soil layer by the transmission torque of the po...

Problems solved by technology

[0005] There are two problems with some existing screw pile installation equipment at home and abroad. One is the high cost of special installation equipment for large screw piles. Since the screw pile foundation has not been widely used, the equipment and machinery purchased at a large cost will be idle for a long time after being used once or twice. cause waste

The second is that the installation depth is small. At present, the existing screw pile installation equipment can only meet the installation of screw piles with a maximum of 10m. The foundation design of transmission lines under some special geological conditions requires the installation depth of screw piles to exceed 50m, which cannot be met by existing equipment.
