Cross-direction supporting pipe fixing device

Abstract

The invention provides a cross-direction supporting pipe fixing device. The problem that since the radian of the end portion of a supporting pipe is difficult to ensure, the building period is long, and work efficiency is affected is solved. The cross-direction supporting pipe fixing device comprises a rigid fixed part, and a sliding groove is formed in the middle of the fixed part in the length direction of the fixed part. The sliding groove is in sliding connection with a plurality of fixed bases in a rotating mode. Each fixed base comprises a sliding block matched with the sliding groove, and the sliding block is provided with an annular hoop. Each hoop comprises an outer ring which is located on the outer circle and made of an elastic material, wherein the upper end of the outer ring is provided with an opening, convex lugs extend outwards from the two ends of the opening, an adjusting bolt is arranged between the two convex lugs, one end of the adjusting bolt is fixedly connected with one of the convex lugs in a rotating mode, and a plurality of arc inner circle portions are fixedly connected to the inner circle of the outer ring at intervals. The cross-direction supporting pipe fixing device ensures the building speed and greatly improves work efficiency.

Description

technical field [0001] The invention relates to a support tube fixing piece for a greenhouse, in particular to a support tube fixing device in a cross direction. Background technique [0002] During the construction of agricultural greenhouses, the upper end of the cross-section is mostly arc-shaped in order to increase the sunlight exposure area, so the skeleton part of the cross-section is mostly made of two butt-joint arc-shaped galvanized steel pipes. It is impossible to use an accurate pipe bending machine, so the ends of the two galvanized steel pipes cannot maintain a tangent structure with the horizontal direction, which causes the ends of the two support pipes to tilt up against each other when they are connected by steel wires. The steel wire is easy to fall off when bundling, and sometimes when the steel pipe has a large warping distance, it is necessary to continuously adjust the radian of the end of the support pipe until the warping distance is within an accept...
