Abstract
The utility model discloses a special column shoe which comprises a bottom plate (1) and iron plates (2). The special column shoe is characterized in that a hot-rolling seamless pipe (3) is welded to the center of the bottom plate (1), the diameter of an inner hole of the hot-rolling seamless pipe (3) is phi 154mm, the length of the hot-rolling seamless pipe (3) is 70mm, and two right-angle sides of each of the four iron plates (2) are connected to the bottom plate (1) and the hot-rolling seamless pipe (3) in a welded mode respectively. The special column shoe is steady in supporting, improves the repeated use rate and saves quantities of used materials.
Description
Technical field
The utility model relates to a kind of supporting instrument, particularly a kind of supporting instrument of hydraulic prop.
Background technology
The post footwear are the used important support materials in down-hole, previously used post footwear are to utilize waste and old U-shaped forging to break into post footwear plate, post footwear circle in the stewing of post footwear plate welding one 12 round steel, pegging graft into sling with 3 fens wire rope is connected with post footwear plate, the post footwear are placed on below the hydraulic prop during use, increase the contact surface on hydraulic prop and ground, and just the aspect ratio of post footwear circle is lower, the effectively slippage of hydraulic prop is being reclaimed the multiplexing very big waste that causes simultaneously.
Summary of the invention
The technical problems to be solved in the utility model: a kind of post footwear are provided, can effectively prevent the slippage of hydraulic prop.
The technical solution of the utility model: a kind of special post footwear comprise: base plate, and iron plate, the welding hot-rolled seamless steel pipe in base plate center, the endoporus of hot rolled seamless steel tube are φ 154mm, length is 70mm; Two right-angle sides of four iron plates are welded in respectively on base plate and the hot rolled seamless steel tube.
The shape right-angled triangle of described iron plate, wherein the junction with base plate and hot rolled seamless steel tube is provided with the hole that can pass the big chain of 40T.
Described base plate is the iron plate that thickness is not less than 12mm.
The beneficial effects of the utility model: the utility model supports firm, and has improved repeat usage, has saved coming into operation of material.
