Description

Technical Field

[0001] The present application relates to the technical field of pipeline welding, and more specifically, to a pipeline welding prefabricated support tool. Background Art

[0002] In the air separation industry, especially the internal pipes of air separation towers, most of them are aluminum pipes, and some are stainless steel pipes. When the air separation tower is installed or fails, the welding of internal pipes is the main workload. The air separation tower is very tall and the internal structure is complex, so on-site construction is very inconvenient. Usually, installation and maintenance personnel use prefabricated pipes and then connect them inside the tower. In addition, the welding quality requirements of low-temperature pipes are high. It is not easy to ensure the welding quality by conventional welding methods, and the work efficiency is low and the labor intensity is high.

[0003] In the related art, in order to facilitate pipeline welding and improve work efficiency, for example, a document with prior art publication number CN213672649U provides a pipeline welding rolling bracket, which supports the pipeline by using the pipeline rolling bracket to make the rotation of the pipeline during welding more convenient, and tightens the adjusting bolt so that the end of the adjusting bolt abuts against the guide rod, thereby fixing the guide sleeve, making it convenient to adjust the distance between the rollers on the left and right sides according to the width of the workpiece, so that the device is easy to adjust.

[0004] Although the above-mentioned prior art solution can achieve the effect of facilitating pipeline rotation welding by supporting the pipeline through rollers with adjustable spacing, when adjusting the distance between the rollers, it is necessary to rotate the adjustment bolt corresponding to each roller. For adjusting multiple groups of rollers, the adjustment process is relatively cumbersome and it is difficult to ensure the symmetry between each group of rollers.

[0005] In view of this, we propose a pipeline welding prefabrication support tool. Utility Model Content

[0006] The purpose of the present application is to provide a prefabricated support tool for pipeline welding, which solves the technical problem that the roller adjustment of the supporting pipeline is not convenient, realizes the technical effect of conveniently adjusting the roller spacing, and ensures the symmetry between the rollers.

[0012] A fixing bolt, wherein the fixing bolt thread is arranged on the inner side of the screw hole, and the fixing bolt passes through the inner side of the through hole.

[0013] By adopting the above technical solution, when adjusting the spacing of the rollers, the pressure plate is loosened by turning the fixing bolts, and the wheel frames can slide on the top of the horizontal slide groove. When one of the wheel frames slides, the other wheel frame is driven to slide in the opposite direction through the transmission assembly, so that the wheel frames drive the rollers to move away from or closer to each other, thereby ensuring the symmetry of the rollers after adjustment. After adjustment, the pressure plate is fixed by turning the fixing bolts, so that the pressure plate presses the wheel frame against the top of the channel steel bracket A, thereby ensuring the stability of the wheel frame after adjustment, and a group of wheel frames can be loosened or tightened at the same time by turning a fixing bolt, thereby making it more convenient to adjust the roller spacing.

[0014] As an optional solution of the technical solution of the present application document, the transmission assembly includes a rack A and a rack B, and the rack A and the rack B are centrally symmetrically meshed on the outside of the gear, and the gear is rotatably arranged on the outside of the fixed shaft, and the fixed shaft is fixedly arranged on the outside of the channel steel bracket A. The ends of the rack A and the rack B that are away from each other are respectively fixed to the two wheel frames, and a slider that slides on the inside of a horizontal slide groove is fixedly arranged at the bottom of the wheel frame.

[0015] By adopting the above technical solution, when one of the wheel frames slides through the slider, the wheel frame drives rack A to slide, so that rack A drives rack B to slide through the gear, and drives the other wheel frame to slide in the opposite direction through rack B, thereby ensuring the symmetry between the rollers.

[0016] As an optional solution of the technical solution of the present application document, a vertical slide groove A is opened on the top of the channel steel bracket A, a slide plate is slidably arranged inside the vertical slide groove A, the slide plate is fixedly arranged at the bottom of the pressure plate, and a scale is opened on the outside of the channel steel bracket A.

[0017] By adopting the above technical solution, when adjusting the spacing of the rollers, the sliding wheel frame drives rack A or rack B to slide, and the distance between the rollers is judged according to the position of rack A or rack B outside the scale, so as to facilitate adjustment according to the diameter of the pipe.

[0018] As an optional solution to the technical solution of the present application document, a vertical slide groove B is symmetrically opened on the top of the channel steel bracket A, and a channel steel bracket B is slidably arranged on the inner side of the vertical slide groove B.

[0019] By adopting the above technical solution, before use, the pipeline support height can be adjusted by sliding the channel steel bracket A outside the channel steel bracket B. After adjustment, the pin is inserted into the first socket at the bottom of the channel steel bracket A to make the channel steel bracket A located at a fixed height to meet different support heights.

[0021] By adopting the above technical solution, the overall stability of the channel steel bracket B and the channel steel bracket A is ensured by arranging a supporting angle steel on the outer side of the channel steel bracket C, and the supporting angle steel is rotated to facilitate storage during movement, thereby reducing the occupied transportation space, and the stability of the supporting angle steel can be maintained by the reinforcement component before and after storage to prevent the supporting angle steel from rotating loose by itself.

At this time, the fixed pin pushes the connecting rod A to rotate and fold the connecting rod B with each other. After folding, the connecting rod A and the stud are fixed by the nut to prevent the supporting angle steel from loosening after storage. When the supporting angle steel is unfolded, the nut is turned to release the fixation of the connecting rod A.

[0035] When adjusting the spacing of the rollers 21, the pressure plate 4 is loosened by rotating the fixing bolt 5. At this time, the wheel frame 2 can slide on the top of the horizontal slide groove 11. When one of the wheel frames 2 slides, the transmission assembly 3 drives the other wheel frame 2 to slide in the opposite direction, so that the wheel frame 2 drives the rollers 21 to move away from or closer to each other, thereby ensuring the symmetry of the rollers 21 after adjustment.
