Abstract

The invention discloses a movable tension rod shaft, relating to a main part of a static pile press and comprising a lug plate internally provided with an upper shaft hole, wherein an upper shaft penetrates through the upper shaft hole, and the outer side of the upper shaft hole is fixedly provided with a baffle plate through a bolt. The movable tension rod shaft also comprises a buckling plate and a steel rope, wherein the buckling plate is connected with the bottom end of the lug plate and a tension rod sleeve and the steel rope penetrates through the sleeve and bypasses the upper shaft; and the bottom end of the steel rope penetrates through a bottom buckle and bypasses a bottom shaft. The movable tension rod shaft has the advantages of simple structure, reliable performance and long service life. Compared with the other traditional tension rod shafts, the service life is prolonged by 500 percent for the movable tension rod shaft and the movable tension rod shaft does not have the conditions of left and right rotation, locking, and breaking during upward lifting.

Description

Technical field: [0001] The invention relates to a main part of a static pile driver, in particular to a movable tie rod shaft. Background technique: [0002] In the prior art, the pull rod shaft of the static pile driver is generally only processed by forging or round steel, which is easy to break during use, and its left and right rotation is not flexible, the processing technology is relatively cumbersome, and the maintenance probability is high. The problem of tie rod shaft is the most troublesome problem for all pile driver manufacturers in China at present. Invention content: [0003] The technical problem to be solved by the present invention is to provide a movable tie rod shaft with simple structure, reliable performance and long service life. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize: [0005] A movable rod shaft, characterized in that: it includes an ear plate with an upper shaft ho...
