Description

Technical Field

[0001] The utility model relates to the technical field of chemical pipeline protection, in particular to a safety protection device for a chemical pipeline. Background Art

[0002] After searching, application number 202321129466.2 discloses a new type of chemical safety protection device, including a half ring, which is provided with two groups and is symmetrically arranged. It also includes a positioning clamping assembly, a threaded rod and a positioning plate. The positioning clamping assembly is arranged on the half ring, and the positioning clamping assembly is arranged in an arc shape. The threaded rod is arranged between the half rings, and the threaded rod is symmetrically arranged. The positioning plate is rotatably arranged at one end of the threaded rod. The positioning clamping assembly includes an electric push rod, a cross plate, a sliding column, a spring and a clamping plate.

[0003] During use, a new type of chemical safety protection device in this patent application controls the electric push rod to extend and drive the horizontal plate to move downward, so that the clamping plate clamps and fixes the outer wall of the chemical pipeline, and then forms a buffer protection for the chemical pipeline through the elastic force of the spring. However, during such use, since the multiple clamping plates on the equipment are respectively controlled by multiple electric push rods, the use cost of the equipment is increased. At the same time, the clamping force formed by the multiple electric push rods on the outer wall of the chemical pipeline through the clamping plate is often uneven, which in turn affects the protection effect of the equipment on the chemical pipeline. For this reason, we propose a safety protection device for chemical pipelines. Utility Model Content

[0015] 1. The safety protection device for a chemical pipeline is provided with a protection mechanism, an adjustment mechanism and a positioning mechanism. When in use, the two protection semi-rings are symmetrically placed at the upper and lower ends of the chemical pipeline, and the two positioning threaded rods are symmetrically threadedly connected to the inside of the positioning threaded grooves on the two connecting plates. The fixing through holes on the four connecting plates are fixedly connected by fixing bolts and fixing nuts. The two positioning threaded rods are rotated to drive the two arc-shaped positioning plates to approach each other and fit the outer wall surface of the chemical pipeline for clamping and fixing operations. At this time, the multiple clamping slide bars drive the arc-shaped clamping plates to elastically contact with the chemical pipeline under the action of the elastic force of the multiple clamping springs, so as to form a buffer protection for the chemical pipeline, and the arc-shaped synchronous plate forces the multiple synchronous force-applying slide bars to drive the multiple clamping slide bars to move synchronously along the inside of the multiple limiting slide barrels through the multiple synchronous linear through grooves thereon, so that the clamping force of the multiple clamping slide bars on the outer wall surface of the chemical pipeline through the arc-shaped clamping plate is uniform, thereby improving the protection effect of the equipment on the chemical pipeline.
