Screw pile machine includes a machine base, stake owner bar, unit head, auger stem formation, stake owner bar is arranged on a machine base, unit head is slidably installed on stake owner bar, and auger stem upper end is connected with unit head, drives auger stem to rotate hole by unit head.
During use, according to the pile foundation degree of depth, select the auger stem of corresponding length.Because the pile foundation degree of depth is larger, so the mobile jib of screw pile machine and the length of auger stem will be corresponding longer, the height that screw pile machine is erect is just higher, and higher its stability that screw pile machine mobile jib stands is just poorer.And need transportation and install also inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of screw pile machine expansion coupling.By expansion coupling, connect auger stem, the overall length that makes auger stem is by can extension elongation, can make the mobile jib height of screw pile machine reduce meeting bore pile foundation hole in the situation that, the corresponding reduction in the high end that screw pile machine is erect, improve screw pile machine stability, simultaneously also convenient transportation and installation.
The utility model screw pile machine uses expansion coupling by upper binding head 1, lower union joint 2, outer sleeve 3, inner sleeve 4, outer cylinder sheath 5, inner cylinder liner 6, sliding sleeve 7, cylinder packing ring 8, slip ring 9, oil distribution casing 18 forms, the chassis 10 that upper binding head 1 is provided with by six side's connectors and its lower end forms, the upper end of outer sleeve 3 is fixedly connected with the chassis 10 of upper binding head 1, the upper dish 20 that lower union joint 2 is provided with by six side's connectors and its upper end forms, the lower end of inner sleeve 4 is fixedly connected with the upper dish 20 of lower union joint 2, outer sleeve 3 is slidably matched with inner sleeve 4 splines, chassis 10 fixed seal connections of the upper end of outer cylinder sheath 5 and inner cylinder liner 6 and upper binding head 1, form the interior outer cylinder of hydraulic cylinder, the lower end of sliding sleeve 7 is fixedly connected with the upper dish 20 of lower union joint 2, sliding sleeve 7 is enclosed within on inner cylinder liner 6 outer ring surfaces and is slidably matched with inner cylinder liner 6, in sliding sleeve 7 upper ends, be fixedly connected with cylinder packing ring 8, cylinder packing ring 8 is slidably matched with the inner ring surface of outer cylinder sheath 5 and the sealing of the outer ring surface of inner cylinder liner 6, on the inner ring surface of the lower end of outer cylinder sheath 5, be fixedly connected with slip ring 9, the outer ring surface of the inner ring surface of slip ring 9 and sliding sleeve 7 is slidably matched, on upper binding head 1, offering fuel feed hole 12 communicates with the cylinder chamber of outer cylinder sheath 5 and 6 formation of inner cylinder liner, at 10 upper ends, chassis of upper binding head 1 and connector 1, be connected and be provided with oil distribution casing 18, 10 upper ends, chassis and 18 of oil distribution casings at connector 1 are provided with plane bearing 19.
When the utility model is used, upper binding head 1 is connected with the unit head of stake machine, and lower union joint 2 and auger stem utilize this expansion coupling to extend the length of auger stem.The overall length that makes auger stem is by can extension elongation, can make the mobile jib height of screw pile machine reduce meeting bore pile foundation hole in the situation that, and the corresponding reduction of height that screw pile machine is erect, improves screw pile machine stability, simultaneously also convenient transportation and installing.
The utility model is structural good, easily manufactured.
