The utility model has the following contents:
the technical problem to be solved by the utility model is as follows: overcome prior art's not enough, provide a regulation formula steel pipe crossing structure base, guarantee crossing structure base and the topography angle of agreeing with under arbitrary slope topography, solved the unable steady supporting of complicated topography base and the inhomogeneous problem of atress.
The technical scheme adopted by the utility model for solving the technical problem is as follows:
an adjustable steel pipe crossing frame base comprises a bottom plate, a vertical plate and a base, wherein the vertical plate is positioned in the middle of the bottom plate and is vertically connected with the bottom plate; a rectangular groove is dug in the middle of the bottom of the base, the rectangular groove in the bottom of the base is buckled outside the vertical plate and fixed through a bolt, a bolt sleeve is arranged outside the bolt, and a limiting pin is inserted into the left end of the bolt; the upper portion of base is provided with the sleeve, and the external diameter phase-match of telescopic internal diameter and steel pipe, the bottom of steel pipe is inserted and is established in the sleeve to fix through the jackscrew.
The side of the vertical plate and the side of the base are respectively and correspondingly provided with a through hole, a bolt sleeve is inserted into the through hole, a bolt is inserted into the bolt sleeve, a matched nut is screwed at the other end of the bolt, a jack is dug on the bolt on the left side of the nut, and a limit pin is inserted into the jack.
The limiting pins are distributed in an R shape.
The base is funnel-shaped distribution.
The utility model has the following positive beneficial effects:
1. the utility model can effectively avoid the problems of uneven stress, broken welding points and the like caused by the untight contact between the base and the ground under the terrain with a certain gradient, and improve the overall safety of the crossing frame; meanwhile, the steel tube crossing frame base is light in overall weight, small in size and convenient to transport.
2. According to the utility model, the bolt sleeve is arranged outside the bolt, so that the transverse shearing force of the bolt is balanced, and the stability of the steel tube crossing frame is improved; through set up the spacer pin at the bolt left end, avoid the condition that the nut appears droing, guaranteed the security of construction.
