[0001] The utility model relates to the technical field of a turning device, in particular to a turning device of a permanent magnet coupling direct-drive water injection system. Background Art

[0002] The permanent magnet coupling direct drive water injection system is a new type of high-efficiency water injection technology. The permanent magnet coupling direct drive system is directly connected to the water injection pump through a coupling, and directly drives the water injection pump to operate at a low speed. During the operation of the permanent magnet coupling direct drive water injection system, the purpose of cranking the system before the water injection pump starts or after it stops is to ensure that the rotor at the drive end is evenly heated or cooled during frequent starts and stops, prevent the rotor from bending and deforming to prevent starting difficulties, eliminate thermal bending of the rotor, reduce the temperature difference between the upper and lower cylinders of the water injection pump, and reduce the impact torque. In addition, manual cranking is required before starting to prevent the permanent magnet coupling direct drive water injection system from getting stuck, but cranking is difficult due to the large friction and the lack of a pulley for transmission.

[0003] During the maintenance of the permanent magnet coupling direct drive water injection system, electric motors and other electrical equipment are not used to ensure safety. Therefore, the existing electric winching device with a motor cannot be used normally. The existing winching device is generally a winching rod or a winching wheel, which rotates the water injection pump by turning the motor. However, the rotor at the driving end is heavy, and the friction of the reciprocating mechanism inside the water injection pump is large. The winching rod or the winching handwheel is difficult to operate, and it is difficult for a single person to operate. In addition, since most of the existing manual winching devices are heavy and difficult to install, it is difficult to adapt to the complex working conditions of different shaft end spacings under different installation and positioning conditions and different heights of the permanent magnet coupling direct drive water injection system. Summary of the invention

[0004] The purpose of the utility model is to provide a permanent magnet coupling direct drive water injection system turning device, so as to achieve the purpose of simple and reliable structure, strong adaptability, easy single-person operation and more labor-saving operation.

[0008] Furthermore, the diameter of the high-speed gear is larger than the diameter of the high-speed gear; the diameter of the low-speed gear is larger than the diameter of the low-speed gear.

[0009] Furthermore, the transmission ratio between the high-speed gear and the high-speed pinion is 9, and the transmission ratio between the low-speed pinion and the low-speed gear is 5.6.

[0010] Furthermore, the mating surface between the output shaft coupling sleeve and the outer extension end of the output shaft is a regular hexagon, and a cylindrical pin hole is provided on the output shaft coupling sleeve; the mating surface between the output shaft coupling sleeve and the rotating shaft of the permanent magnet coupled direct-drive water injection system is provided with a keyway, and the rotating shaft of the permanent magnet coupled direct-drive water injection system is connected through the keyway and the key.

Since the diameter of the high-speed large gear is larger than the diameter of the high-speed small gear, and the diameter of the low-speed large gear is larger than the diameter of the low-speed small gear, the transmission component plays a role in reducing the rotation speed and increasing the torque. In this way, it is more labor-saving to hand-crank the input shaft handle, and it is easier to crank by one person. By adjusting the height of the support base, it can adapt to permanent magnet coupling direct drive water injection systems of different heights, and has a wide range of applications.

[0024] like Figure 1-Figure 10 As shown, the present invention provides a permanent magnet coupling direct drive water injection system winch device, which is specifically composed of a gearbox, an output shaft coupling sleeve 42, an input shaft handle 41 and a transmission assembly. The above-mentioned gearbox includes a box body 11 and a box cover 12. Specifically, the transmission assembly is arranged in the gearbox, and the transmission assembly also includes an input shaft 311, a high-speed pinion 312, a high-speed gear 32, an intermediate shaft 34, a low-speed pinion 33, a low-speed gear 35, and an output shaft 36. The input shaft and the high-speed pinion are an integrally formed structure. The input shaft, the intermediate shaft, and the output shaft are rotatably arranged in the gearbox, one end of the input shaft extends outward through the gearbox, and the outer extension end of the input shaft is fixedly connected to the input shaft handle, so that the input shaft handle and the input shaft are synchronously rotated. The high-speed pinion is arranged on the input shaft, the high-speed gear and the low-speed pinion are arranged on the intermediate shaft, and the high-speed gear, the low-speed pinion and the intermediate shaft rotate synchronously. The low-speed gear is arranged on the output shaft, the high-speed pinion is meshed with the high-speed gear, the high-speed gear rotates synchronously with the low-speed pinion, and the low-speed pinion is meshed with the low-speed gear, wherein the diameter of the high-speed gear is larger than the diameter of the high-speed pinion of the input shaft, so as to achieve the effect of deceleration and torque amplification, and the diameter of the low-speed gear is larger than the diameter of the low-speed pinion, so as to further achieve the effect of deceleration and torque amplification. In addition, one end of the output shaft extends outward through the gear box, and the outer extension end of the output shaft is connected to the coupling sleeve, and the output shaft coupling sleeve is used to connect the rotating shaft of the permanent magnet coupling direct drive water injection system.

[0025] The transmission assembly of the utility model adopts a two-stage cylindrical gear set structure, including a high-speed gear set and a low-speed gear set. The high-speed gear set includes a high-speed pinion and a high-speed gear. The input shaft high-speed pinion and the high-speed gear are respectively arranged on the input shaft and the intermediate shaft, and the diameter of the high-speed gear is larger than the diameter of the input shaft high-speed pinion. Preferably, the transmission ratio between the high-speed gear and the high-speed pinion is 9. At the same time, the low-speed pinion is also arranged on the intermediate shaft and meshes with the low-speed gear. The high-speed gear and the low-speed pinion have the same rotation speed. Since the diameter of the high-speed gear is larger than the diameter of the low-speed pinion, the linear speed of the low-speed pinion is smaller than the linear speed of the high-speed gear. At the same time, the rotation speed of the low-speed gear is smaller than the rotation speed of the low-speed pinion. Preferably, the transmission ratio between the low-speed pinion and the low-speed gear is 5.6. Therefore, the speed of the low-speed large gear can be further reduced and the torque can be increased through the intermediate shaft. The operator only needs less effort to shake the input shaft handle to drive the permanent magnet coupled direct drive water injection system.

[0026] like Figure 8-Figure 10 As shown, in one embodiment of the utility model, the input shaft, the intermediate shaft, and the output shaft are respectively assembled on the gear box through the deep groove ball bearing 51 and the end cover 21. A sleeve 24 is provided between the high-speed gear and the deep groove ball bearing, between the low-speed pinion and the deep groove ball bearing, and between the low-speed gear and the deep groove ball bearing. The axial positioning of each gear can be achieved through the cooperation of the shaft shoulder and the sleeve, so that the gear does not slip axially when it is running.

[0027] like Figure 3 As shown, in one embodiment of the utility model, the mating surface 421 between the output shaft coupling sleeve and the outer extension end of the output shaft is a regular hexagon, which is radially fixed to the output shaft through the regular hexagonal cross section, and the torque is transmitted by synchronous rotation. In addition, a cylindrical pin hole 423 is also provided on the output shaft coupling sleeve, and after the output shaft and the output shaft coupling sleeve are matched, axial fixation is performed to avoid the sleeve from sliding during operation and causing safety problems. In addition, the mating surface between the output shaft coupling sleeve and the rotating shaft of the permanent magnet coupling direct drive water injection system is provided with a keyway 422, and the rotating shaft of the permanent magnet coupling direct drive water injection system is connected by the keyway and the key. The utility model can be more widely adapted to the permanent magnet coupling direct drive water injection system and the fixed position of the winch base, as well as the complex working conditions such as the small distance between the output shaft and the permanent magnet coupling direct drive water injection system through the output shaft coupling sleeve.

[0028] like Figure 6As shown, in one embodiment of the utility model, a support base is provided at the bottom of the gearbox, and a retractable support leg is provided below the support base, and is fixed with a limit bolt. In a specific embodiment of the utility model, the support base includes a support plate 61, a support leg and a limit bolt 63, the support leg is arranged at the bottom of the support plate and is arranged in a rectangular shape, and the gearbox is positioned and installed with the support plate through the countersunk bolt hole at the bottom. The support leg further includes an upper support leg 621 and a lower support leg 622, and the lower support leg can be slidably inserted in the upper support leg, and the length adjustment and fixation between the two are achieved by the limit bolt. The support base in this embodiment plays a role in supporting and stabilizing the gearbox, so that the output shaft and the permanent magnet coupling direct drive water injection system are accurately aligned horizontally, which facilitates the connection of the output shaft coupling sleeve with the permanent magnet coupling direct drive water injection system. The support leg realizes the telescopic function through the cooperation and sliding of the upper support leg and the lower support leg, and its length can be adjusted according to the horizontal height of the end of the permanent magnet coupling direct drive water injection system, thereby adjusting the height of the output shaft, so that the manual turning device can be adapted to various types of water injection pumps. Optionally, a chassis 64 is provided at the bottom end of the supporting leg, and the cross-sectional area of ​​the chassis is larger than the cross-sectional area of ​​the supporting leg. The provision of the chassis can further improve the stability of the gear box, making the gear box less likely to tip over.

[0029] When the utility model is used, the height of the support leg is first adjusted so that the output shaft coupling sleeve is connected to the rotating shaft of the permanent magnet coupling direct drive water injection system, the limit bolt is turned and tightened to fix the support leg, and then the input shaft handle is shaken, through the input shaft, high-speed pinion, high-speed gear, intermediate shaft, low-speed pinion and low-speed gear, and the torque is transmitted to the output shaft, and then the permanent magnet coupling direct drive water injection system is turned until the turning work is completed. The utility model can adapt to different shaft end spacings under different installation and positioning conditions and complex working conditions of different heights of the permanent magnet coupling direct drive water injection system. It has a simple and reliable structure, strong adaptability, is easy to operate by one person, and is more labor-saving to operate.
