Embodiment Construction
[0012] The telescopic joint for the screw pile machine of the present invention consists of an upper connector 1, a lower connector 2, an outer sleeve 3, an inner sleeve 4, an outer cylinder liner 5, an inner cylinder liner 6, a sliding sleeve 7, a cylinder liner sealing ring 8, a sliding sleeve ring 9 and an oil distribution plate 18. The upper connector 1 is composed of a hexagonal connector and a chassis 10 provided at its lower end. The upper end of the outer sleeve 3 is welded and fixedly connected to the chassis 10 of the upper connector 1. The lower connector 2 is composed of The hexagonal connector and the upper plate 20 provided at its upper end are composed of the lower end of the inner sleeve 4 and the upper plate 20 of the lower connector 2 are welded and fixedly connected, the outer sleeve 3 and the inner sleeve 4 are splined for sliding fit, and the outer cylinder sleeve 5 and the upper end of the inner cylinder liner 6 are fixed and sealed with the chassis 10 of ...

An expansion coupling for a screw pile machine is composed of an upper connecting head (1), a lower connecting head (2), an outer sleeve (3), an inner sleeve (4), an outer cylinder sleeve (5), an inner cylinder sleeve (6), a sliding sleeve (7), a cylinder sleeve sealing ring (8), a sliding ring (9) and an oil distribution disc (18). The outer cylinder sleeve (5), the inner cylinder sleeve (6), the cylinder sleeve sealing ring (8) and the sliding sleeve (7) form a hydraulic cylinder mechanism which drives the outer sleeve (3) and the inner sleeve (4) in spline fit to stretch or shrink, the hydraulic cylinder mechanism is arranged at the upper end of a spiral drill pipe of the screw pile machine in a connected mode, the total length of the spiral drill pipe can be extended to reduce the height of a main rod of the screw pile machine, the vertical height of the screw pile machine is correspondingly reduced, and stability of the screw pile machine is improved.
Description
technical field [0001] The invention relates to pile foundation construction equipment used in building construction, in particular to screw pile machine equipment. Background technique [0002] The screw pile driver consists of a pile driver base, a pile driver main rod, a power head, and an auger drill rod. The power head is connected, and the auger rod is driven by the power head to rotate for drilling. [0003] When using, select the auger rod of the corresponding length according to the depth of the pile foundation. Due to the large depth of the pile foundation, the length of the main rod of the screw pile machine and the auger drill rod will be correspondingly longer, so that the height of the screw pile machine will be higher, and the higher the main rod of the screw pile machine will be, the greater its stability will be. worse. And it is inconvenient to transport and install. Contents of the invention [0004] The object of the present invention is to provide ...
