Description

Technical Field

[0001] The invention relates to flange glue coating equipment, in particular to a semi-automatic flange glue coating machine and a use method thereof, which can coat glue on steel flanges at both ends of an oil delivery rubber pipe. Background Art

[0002] Offshore oil hose is a special rubber pipe that can bear high oil pressure. It is a marine engineering product with high technical content and high added value. It is mainly connected to the oil production platform and the oil tanker, responsible for the transmission of oil. Offshore oil transportation technology has become an increasingly perfect rubber hose technology in the field of oil and gas exploration and research and development. A very long oil pipeline is formed by the mutual connection of flanges at both ends of each oil hose. Offshore oil hose is a bonded pipe with a complex structure. It is mainly made of multiple layers of rubber, metal wire and other composite materials (such as mesh and cord) through vulcanization. The anti-corrosion technology of the end face flange of the oil hose in seawater and the close fitting connection between the flange and the rubber pipe body are the key technologies that affect the service life of the oil pipeline. The current flange gluing method is mainly manual operation, and there is no special equipment for gluing the surface of this flange. It is difficult to control the uniformity of the rubber adhesive applied on the flange surface by manual operation, and the rubber adhesive cannot be air-dried quickly after application.

[0003] In addition, the film thickness of the rubber adhesive applied on the surface of the flange is uneven, which seriously affects the fusion and bonding of the flange and the rubber pipe body, and greatly affects the service life of the oil hose. Summary of the invention

The two ends of the spindle 6 are respectively connected to the turntable 8 linked to the spindle 6, and the turntable 8 is a circular disk, which is key-connected to the end of the spindle 6 and fixed to the spindle 6 by a locking nut 10. There are multiple long holes 24 evenly distributed on the turntable 8 along the circumferential direction, and the length direction of the long hole 24 is the radial direction of the turntable 8. The glue coating machine of the present invention is suitable for flanges 22 of class 150 and class 300 of the American standard flanges. Different types of flanges 22 will be used according to the diameter of the oil pipe body; different types of flanges 22 will also have different installation dimensions. The long hole 24 on the end face of the turntable 8 of the present invention is to adapt to the installation of flanges 22 of different types.

[0029] The power transmission device 2 includes a power source and a transmission mechanism. The power source is installed on the machine base 5 and is connected to the main shaft 6 through the transmission mechanism. The power source of this embodiment includes a motor 16 and a reducer 15. The transmission mechanism includes an electromagnetic clutch 14, a small toothed pulley 13, a toothed belt 12 and a large toothed pulley 9. The motor 16, the reducer 15, the electromagnetic clutch 14 and the small toothed pulley 13 form an integral structure and are fixed on the machine base 5. The reducer 15 is connected to the output shaft of the motor 16 to reduce the output speed of the motor 16; the electromagnetic clutch 14 is assembled on the output shaft of the reducer 15, the small toothed pulley 13 is installed on the electromagnetic clutch 14, and the large toothed pulley 9 is installed in the middle of the main shaft 6 and is axially fixed on one side of the large toothed pulley 9 with two round nuts 11, and the other side of the large toothed pulley 9 is fixed through the shoulder on the main shaft 6. The small toothed pulley 13 is connected to the large toothed pulley 9 through the toothed belt 12, and the rotation speed is reduced to the rotation speed required by the main shaft rotating device 1 through the transmission of the toothed belt 12, and it bears the main power output of the glue coating machine of the present invention.

[0030] The drawer oil receiving device 4 is located below the main shaft 6 and also below the machine base 5, and includes a left drawer 19, a right drawer 20 and a drawer rail 21. The drawer rail 21 is installed on the machine base 5. The left drawer 19 and the right drawer 20 are respectively slidably connected to the drawer rail 21. After being pulled out, the left drawer 19 and the right drawer 20 are respectively located below the turntable 8 at both ends of the main shaft 6.

[0031] The top of the machine base 5 is provided with an outer cover 23 located between the two end turntables 8. The main shaft part between the two end turntables 8, the large toothed pulley 9 and the round nut 11 installed on the main shaft 6, and the supporting bearings 7 at both ends of the main shaft 6 are all covered by the outer cover 23. An auxiliary device 3 is installed on the top of the machine base 5 on one side of the main shaft 6. The auxiliary device 3 includes a tool box 17 and a storage box 18. The storage box 18 is located above the tool box 17. The flange 22 to be glued is fixed on the turntable 8 by bolts and nuts. The bolts and nuts are placed in the storage box 18; the tools or standard parts that are not used at ordinary times are stored in the tool box 17, and the commonly used tools are placed in the storage box 18.

[0032] The method of using the glue coating machine of the present invention is:

[0033] During operation, the electromagnetic clutch 14 is powered off, so that the reducer 15 is disengaged from the small toothed pulley 13, and the main shaft 6 and the turntable 8 at both ends are manually rotated. The flange 22 of the offshore oil pipeline to be glued is fixed to the turntable 8 with bolts and nuts by manual operation. The left drawer 19 and the right drawer 20 are pulled outward respectively, so that the left drawer 19 and the right drawer 20 are moved to the specified position on the drawer track 21 (i.e., below the turntable 8 at both ends of the main shaft 6) along the drawer track 21. The electromagnetic clutch 14 is powered on and closed, and the low speed gear (speed of 5r / min) of the motor 16 is turned on, and the motor 16 drives the turntable 8 to rotate at a low speed. The operator stands at both ends of the offshore oil pipeline flange 22, and uses a brush to apply the rubber adhesive evenly on the surface of the flange 22 at one end or both ends of the main shaft 6, and the excess rubber adhesive falls off in the left drawer 19 and / or the right drawer 20. After the rubber adhesive is applied to the surface of the flange 22, the motor 16 is switched to the medium speed gear (rotation speed of 30 r / min) or the high speed gear (rotation speed of 60 r / min), and the rubber adhesive on the surface of the flange 22 is quickly dried during the rotation process.

[0034] When the flange 22 is installed, the end surface of the turntable 8 is close to the end surface of the flange 22, ensuring that the force on the flange 22 is uniform and reliable when the flange 22 rotates. When the glue coating machine is working, the rubber adhesive can be applied to the surface of the flange 22 installed on the turntable 8 at one end of the main shaft 6, or the rubber adhesive can be applied to the surface of the flange 22 installed on the turntable 8 at both ends of the main shaft 6.

[0035] The present invention simplifies the process of coating the outer surface of the flange with rubber adhesive, and constantly controls the uniformity of the outer surface of the flange with rubber adhesive. The coating machine shows flexibility and diversity during operation, which has a great influence on the corrosion resistance of the oil pipe flange and the service life of the oil pipe.

[0036] When the present invention is used, different flange models are used according to different diameters of each oil pipeline body. The present invention is based on the premise that workers can operate the equipment easily and the rubber adhesive applied on the surface of the flange is uniform. The motor is used as a power element to control the rotation speed of the flange accordingly.
