Petroleum refining pipeline flange butt joint equipment capable of avoiding abrasion and dislocation

Abstract

The invention discloses petroleum refining pipeline flange butt joint equipment capable of avoiding abrasion and dislocation in the technical field of flange mounting equipment. A bottom plate, a mounting frame, a sliding rod and sliding sleeves are included, two groups of connecting blocks are in cup joint to the outer wall of a threaded rod, the outer walls of the bottoms of the connecting blocks are fixedly connected with the outer walls of the tops of the sliding sleeves, and fixing devices are arranged on the outer walls of the bottoms of the sliding sleeves. A detection device is arranged on the outer wall of the bottom of the sliding rod, the left end and the right end of the detection device are connected with the outer walls of the sides, close to each other, of the two sets of fixing devices correspondingly, the device inclines along with dislocation of the fixing devices through a mounting rod, conductive liquid flows towards one side of a storage groove, conductive pieces inside are connected, an LED lamp is powered on to work, and the prompting effect is achieved; and a worker can know the dislocation condition of the two fixing devices in time, timely adjustment is facilitated, the phenomenon that the flange plate is damaged in the installation process due to dislocation is avoided, and the sealing performance of pipeline installation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of flange mounting equipment, in particular to pipeline flange butt joint equipment for petroleum refining that can avoid wear and dislocation. Background technique [0002] When docking the flanges of the oil refining pipe, in order to facilitate the docking of the flanges, it is necessary to fix the flanges, and then make the two sets of flanges close together for docking. The application number is CN201711211403.0 This method is disclosed in the public document of a pipe flange butt joint device for petroleum refining. However, during the butt joint process, the sliding block that moves with the fixing device will slide on the outer wall of the slide rail, and the long-term work sliding will cause The slider is worn, and the degree of wear is uncontrollable and uneven, which will cause the two sets of fixing devices to fall and displace, resulting in the two sets of fixing devices not being at the same le...

[0002] When docking the flanges of the oil refining pipe, in order to facilitate the docking of the flanges, it is necessary to fix the flanges, and then make the two sets of flanges close together for docking. The application number is CN201711211403.0 This method is disclosed in the public document of a pipeline flange butt joint device for petroleum refining. However, during the butt joint process, the sliding block that moves with the fixing device will slide on the outer wall of the slide rail, and the long-term work sliding will cause The slider is worn, and the degree of wear is uncontrollable and uneven, which will cause the two sets of fixing devices to fall and dislocate, resulting in the two sets of fixing devices not being at the same level. If the degree of dislocation is small, the staff will If it cannot be found directly, it will lead to misalignment of the butt flanges, making it easy for the bolts to collide and rub against the flanges when they pass through the mounting holes on the flanges, easily causing damage to the butt flanges, and affecting the pipe installation Sealing, for this reason, we propose a pipeline flange butt joint equipment for petroleum refining that can avoid wear and dislocation
