Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a pipeline grinding device for marine engineering. Background Art

[0002] Offshore pipelines refer to pipeline systems laid on the seabed for transporting oil and natural gas. These pipelines typically include submarine oil and gas gathering pipelines, trunk pipelines and attached booster platforms, as well as main pipes connecting the pipelines to the platforms. The main purpose of offshore pipeline projects is to collect oil or natural gas extracted from offshore oil and gas fields and transport them to single-point moorings for moored oil tankers or onshore oil and gas storage stations.

[0003] In order to weld multiple marine pipelines together, a grinding device is generally used to grind the end faces of the marine pipelines flat to facilitate welding. Currently, most existing grinding devices are cylindrical structures. When in use, the marine pipeline needs to be inserted into the cylinder and fixed, so that the grinding wheel installed in the cylinder can be used for grinding. Although the existing grinding devices can achieve a high degree of grinding flatness.

[0004] However, the existing grinding devices are not convenient for directly grinding both ends of the marine pipeline. After grinding one end of the marine pipeline, the marine pipeline needs to be pulled out of the barrel and then replaced with the other end for grinding, which is quite troublesome and seriously affects the grinding efficiency of the marine pipeline and cannot meet the processing requirements. Therefore, a marine engineering pipeline grinding device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a pipeline grinding device for marine engineering, which solves the problem that the existing grinding devices are not convenient for directly grinding the two ends of the marine pipeline. After grinding one end of the marine pipeline, the marine pipeline needs to be pulled out of the barrel and then replaced with the other end for grinding, which is quite troublesome and seriously affects the grinding efficiency of the marine pipeline and cannot meet the processing requirements.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a pipeline grinding device for marine engineering, comprising a frame, a partition being fixedly connected to the inner side of the frame, and a movable grinding mechanism being provided on the frame;

[0007] The movable grinding mechanism includes an installation box fixedly connected to the bottom of the partition, a rotating motor is fixedly installed on the right side of the installation box, the output shaft of the rotating motor is fixedly connected to a screw rod, the outer surface of the screw rod is threadedly sleeved with a threaded sleeve, the top of the threaded sleeve is fixedly connected to a support column around the top, the top of the support column is fixedly connected to a mounting platform, a fixing bracket is installed on the top of the mounting platform, a lower pressure plate is provided on the top of the fixing bracket, positioning holes are provided at the front and rear ends of the fixing bracket and the lower pressure plate, a positioning bolt is provided inside the positioning hole, a positioning nut is threadedly sleeved on the outer surface of the positioning bolt, and semicircular grooves of the same size are provided on the inner sides of the fixing bracket and the lower pressure plate.

[0008] Furthermore, a grinding motor, a fan and a box body are fixedly connected to the left and right sides of the frame, and a grinding wheel is fixedly connected to the output shaft of the grinding motor.

[0009] Furthermore, the fan is connected to the box body, and the top of the box body is fixedly connected to an aluminum alloy suction pipe with one end penetrating the frame and extending to the bottom of the grinding wheel.

[0010] Furthermore, an isolation net is fixedly connected to the interior of the box, and a sealing door is hinged on the front of the box.

[0011] Furthermore, the tops of the installation box and the partition are both provided with openings, and the support columns pass through the openings.

[0012] Furthermore, a limiting rod is fixedly connected to the inner side of the installation box, and the limiting rod is slidably connected to the threaded sleeve.

[0013] Furthermore, the frame and the partition are both made of stainless steel, and a marine pipeline is provided on the inner side of the semicircular groove.

[0014] Furthermore, the rotating motor is a forward and reverse rotating motor, and a protective shell is provided on the outside of the rotating motor.

[0015] Furthermore, the positioning holes of the fixing frame and the lower pressing plate are of the same size and have the same number.

[0016] Furthermore, the end face of the screw rod is rotatably connected to the inner wall of the installation box, and the threaded sleeve is cylindrical.

[0017] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0018] The marine engineering pipe grinding device realizes the effect of directly grinding both ends of the marine pipe by setting a mobile grinding mechanism. During the grinding period, there is no need to repeatedly disassemble and assemble the marine pipe, and there is no need to remove the marine pipe and replace it with the other end for grinding after grinding at one end. It is more convenient, improves the grinding efficiency of the marine pipe, and is more conducive to processing. When in use, the staff first needs to place the marine pipe on the inside of the fixing frame, and then cover the top of the marine pipe with the lower pressure plate so that the hole positions of the positioning holes coincide and the two semicircular grooves close to form a circle. At this time, the positioning bolt is inserted into the positioning hole and tightened. By tightening the positioning nut, the marine pipeline can be fixed for grinding. Subsequently, the rotating motor and the grinding motor are started to make the screw and the grinding wheel rotate clockwise at the same time. When the screw rotates clockwise, it can drive the threaded sleeve to move to the left. Therefore, through the cooperation of the support column and the mounting platform, the fixed marine pipeline is continuously approached to the rotating grinding wheel, thereby grinding the end face flat. In addition, when the end face grinding is completed, the staff only needs to control the output shaft of the rotating motor to rotate counterclockwise to drive the threaded sleeve to move to the right, and finally grind the other end of the marine pipeline.

At this time, the positioning bolts 12 are inserted into the positioning holes 11 and the positioning nuts 13 are tightened to fix the marine pipeline for easy grinding. Subsequently, the rotating motor 4 and the grinding motor 15 are started, so that the screw rod 5 and the grinding wheel 16 can rotate clockwise at the same time.

[0027] Among them, when the screw rod 5 rotates clockwise, it can drive the threaded sleeve 6 to move to the left, so that through the cooperation of the support column 7 and the mounting platform 10, the fixed marine pipeline is continuously approached to the rotating grinding wheel 17, thereby performing the end face grinding process. In addition, when the end face grinding is completed, the staff only needs to control the output shaft of the rotating motor 5 to rotate counterclockwise to drive the threaded sleeve 6 to move to the right, and finally grind the other end of the marine pipeline.

[0028] It should be noted that the fixing frame 9 is fixed to the top of the mounting platform 8 by screws.

The end face of the screw rod 5 is rotatably connected to the inner wall of the mounting box 3, and the threaded sleeve 6 is cylindrical.

[0032] The working principle of the above embodiment is:

[0033] During use, the staff first needs to place the marine pipeline on the inner side of the fixing frame 9, and then cover the lower pressure plate 10 on the top of the marine pipeline so that the hole positions of the positioning holes 11 coincide and the two semicircular grooves 14 close together to form a circle. At this time, the positioning bolt 12 is inserted into the positioning hole 11 and the positioning nut 13 is tightened to fix the marine pipeline for grinding. Subsequently, the rotating motor 4 and the grinding motor 15 are started to make the screw rod 5 and the grinding wheel 16 rotate clockwise at the same time.
