Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe oiling mechanisms, and specifically relates to a surface oiling mechanism for seamless steel pipe quality inspection. Background Technique

[0002] The inspection and oiling of seamless steel pipes are important links in the steel pipe production process, which respectively ensure the quality of the steel pipes and the convenience of subsequent use. The inspection of seamless steel pipes involves multiple aspects, mainly including geometric dimension and shape inspection, surface quality inspection, and physical and chemical properties and process performance inspection. The oiling of seamless steel pipes is an important step in the production process, which helps to prevent the steel pipes from rusting and corroding during storage and transportation. The oiling is usually carried out after the steel pipes pass the quality inspection and are confirmed to be qualified.

[0003] The utility model patent with the publication number of CN208878886U discloses a seamless steel pipe oiling device, the structural composition of which includes a conveying support, a conveyor belt, a conveying motor, a driving roller, a first support plate, a second support plate, a driven roller and an oil spraying tank. The conveying motor is fixedly installed on one side of the conveying support, the driving end of the conveying motor is fixedly connected with the driving roller, the two second support plates and the driven roller are located on the other side of the conveying support, both ends of the driven roller are rotatably connected with the two second support plates respectively, the conveyor belt is sleeved on the driving roller and the driven roller, and the conveyor belt is slidably connected above the conveying support. The oil spraying tank is fixedly installed at the central position above the conveying support, and a rotating mechanism is installed on one side of the conveying support away from the conveying motor. The utility model oils the steel pipes comprehensively and evenly, and has high oiling quality.

[0004] However, when the above device is used, since only one side of the pipe fitting can be oiled each time, it is necessary to go through two oiling steps to complete the oiling of the entire outer surface of the pipe fitting. And in one oiling step, it is necessary to wait for the oil spraying tank to finish walking the entire length of the pipe fitting to complete the oiling of one side of the pipe fitting, resulting in low oiling efficiency. Therefore, in view of the above problems, a surface oiling mechanism for seamless steel pipe quality inspection is proposed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a surface oiling mechanism for quality inspection of seamless steel pipes, wherein the steel pipe oiling mechanism can drive the pipe mounted therebetween to rotate by the rotation of two oiling rollers, and at the same time, part of the oiling roller is located in the oil storage tank, so that when it rotates, the oil can be brought out and evenly brushed on the surface of the pipe, and finally the entire pipe can be oiled while the pipe is rotated, which can greatly improve the oiling efficiency. In addition, in order to prevent the oil from causing insufficient friction between the oiling roller and the pipe, so that the pipe slips, during oiling, the hydraulic cylinder can drive the movable frame to descend, so that the auxiliary driving roller is pressed on the upper side of the pipe and drives it to rotate at the same time, so that the driving force exerted on the pipe can be significantly improved, so that it can rotate continuously without slipping, and solves the technical problems that it is impossible to simultaneously oil all parts of the outer surface of the pipe in the prior art, and that in one oiling step, it is necessary to wait for the oiling equipment to complete the entire length of the pipe before completing the oiling work on one side of the pipe, thereby resulting in low oiling efficiency.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A surface oiling mechanism for quality inspection of seamless steel pipes, comprising an oil storage tank, in which an oiling roller for oiling pipe fittings is rotatably arranged, a hydraulic cylinder, whose output shaft frame is provided with a movable frame, on which an auxiliary driving roller is rotatably arranged, and a roller driving mechanism, which is used to drive the oiling roller and the auxiliary driving roller to rotate, wherein two oiling rollers are provided, and the two oiling rollers are connected by a linkage member provided at the ends, and the oiling roller consists of a roller body and an oiling sleeve layer provided on the outside, and the outer surface of the oiling sleeve layer is provided with velvet bristles.

[0008] Through the above-mentioned structural form, the rotation of the two oiling rollers can drive the pipe mounted therebetween to rotate along with it, and at the same time, part of the oiling rollers is located in the oil storage tank, so that when it rotates, it can bring out the oil and evenly apply it to the surface of the pipe, ultimately achieving the goal of rotating the pipe while oiling the entire pipe, which can greatly improve the oiling efficiency; in addition, in order to prevent the oil from causing insufficient friction between the oiling rollers and the pipe, causing the pipe to slip, during oiling, the hydraulic cylinder can drive the movable frame to descend, so that the auxiliary driving roller is pressed on the upper side of the pipe and drives it to rotate at the same time, thereby significantly improving the driving force received by the pipe, allowing it to rotate continuously without slipping.

[0009] In a possible implementation, the movable frame includes a frame plate, and two auxiliary drive rollers are rotatably arranged on the lower side of the frame plate. The two auxiliary drive rollers are transmission-connected via linkage members arranged at the ends.

[0010] With the above structural form, due to the provision of the linkage member, it is possible to ensure the synchronous rotation of the two auxiliary drive rollers, so that only one set of roller drive mechanisms needs to be provided to achieve the synchronous drive of the two auxiliary drive rollers.

[0011] In a possible implementation manner, each linkage member includes two friction wheels, which are installed at both ends of the oiling roller and the auxiliary drive roller, and the friction wheels are connected by a transmission belt.

[0015] In a possible implementation manner, the roller drive mechanism includes a drive motor, a driving wheel and a driven wheel. The driving wheel is fixedly connected to the output shaft of the drive motor, the driven wheel is fixedly connected to the ends of the oiling roller and the auxiliary drive roller, and the driving wheel and the driven wheel are connected by a drive belt.

[0017] In a possible implementation manner, an oil storage tank is provided in the oil storage pool, and an oil liquid is stored in the oil storage tank. When the oil storage tank is full of the oil liquid, the liquid level height does not exceed the horizontal plane where the central axis of the oiling roller is located.

[0018] With the above structural form, when the oiling roller rotates, it can take out the oil liquid attached to its surface and brush it onto the surface of the pipe fitting.

[0019] In a possible implementation manner, protective cover plates are provided on both sides of the oil storage pool, and the protective cover plates can completely cover the linkage members.

[0020] With the above structural form, the protective cover plates can protect the linkage members and prevent external foreign objects from falling onto the linkage members and causing damage to their work.

[0021] In a possible implementation, support feet arranged in the center are fixedly provided on both sides of the shelf board, and the output shaft end of the hydraulic cylinder is fixedly connected to the support feet.

[0022] Through the above structural form, the transmission connection between the hydraulic cylinder and the shelf board can be realized.

[0023] To sum up, the utility model includes the following beneficial technical effects:

[0024] The rotation of two oiling rollers can drive the pipe fittings erected therebetween to rotate accordingly. At the same time, part of the oiling rollers are located in the oil storage tank, so that the oil can be taken out when they rotate and evenly coated on the surface of the pipe fittings. Finally, the whole pipe fitting can be oiled while rotating, which can greatly improve the oiling efficiency.

[0025] In addition, in order to prevent insufficient friction between the oiling rollers and the pipe fittings caused by the oil, resulting in the slipping of the pipe fittings, during oiling, the hydraulic cylinder can drive the movable frame to lower, so that the auxiliary driving roller presses on the upper side of the pipe fitting and drives it to rotate at the same time. In this way, the driving force received by the pipe fitting can be significantly increased, enabling it to rotate continuously without slipping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0034] like Figure 1 - Figure 3 As shown, the present embodiment provides a surface oiling mechanism for quality inspection of seamless steel pipes, comprising an oil storage tank 1, in which an oiling roller 2 for oiling the pipe fittings is rotatably arranged, wherein two oiling rollers 2 are arranged in total, and the two oiling rollers 2 are transmission-connected by a linkage member 7 arranged at the ends, the oiling roller 2 is composed of a roller body 21 and an oiling sleeve 22 arranged externally, and the outer surface of the oiling sleeve 22 is provided with velvet bristles, and through the above-mentioned structural form, the two oiling rollers 2 can be rotated to drive the pipe fittings mounted therebetween to follow the rotation, and at the same time, part of the oiling roller 2 is located in the oil storage tank 1, so that when it rotates, it can bring out the oil and evenly apply it on the surface of the pipe fitting, and finally realize oiling the entire pipe fitting while rotating, which can greatly improve the oiling efficiency.

[0035] In addition, hydraulic cylinders 3 are provided on both sides of the oil storage tank 1, and a movable frame 4 is provided on its output shaft frame. An auxiliary driving roller 5 is rotatably provided on the movable frame 4, and a roller driving mechanism 6 is used to drive the oiling roller 2 and the auxiliary driving roller 5 to rotate. In order to prevent the oil from causing insufficient friction between the oiling roller 2 and the pipe fitting, causing the pipe fitting to slip, when oiling, the hydraulic cylinder 3 can drive the movable frame 4 to descend, so that the auxiliary driving roller 5 is pressed on the upper side of the pipe fitting and drives it to rotate at the same time, thereby significantly improving the driving force exerted on the pipe fitting, allowing it to rotate continuously without slipping.

[0036] like Figure 4 As shown, the movable frame 4 includes a frame plate 41, and two auxiliary driving rollers 5 are rotatably arranged on the lower side of the frame plate 41. The two auxiliary driving rollers 5 are connected by a linkage member 7 arranged at the end. Through the above-mentioned structural form, since the linkage member 7 is arranged, it can ensure that the two auxiliary driving rollers 5 rotate synchronously, so that only one set of roller driving mechanism 6 is required to realize the synchronous driving of the two auxiliary driving rollers 5 to rotate.

[0037] In addition, centrally arranged support feet 42 are fixedly provided on both sides of the frame plate 41, and the output shaft end of the hydraulic cylinder 3 is fixedly connected to the support feet 42. Through the above-mentioned structural form, a transmission connection between the hydraulic cylinder 3 and the frame plate 41 can be achieved.

[0038] like Figure 3As shown in the figure, each linkage member 7 includes two friction wheels 71. The friction wheels 71 are installed at both ends of the oiling roller 2 and the auxiliary drive roller 5. The friction wheels 71 are drivingly connected by a transmission belt 72. With the above structural form, due to the frictional effect between the friction wheels 71 and the transmission belt 72, when one friction wheel 71 rotates, it can drive the other friction wheel 71 to rotate synchronously, thereby achieving the linkage effect.

[0039] As Figure 5 shown in the figure, the auxiliary drive roller 5 includes a roller 51 and an anti-slip sleeve layer 52 sleeved outside. A plurality of groups of through oil holes 53 are opened in both the roller 51 and the anti-slip sleeve layer 52. With the above structural form, the anti-slip sleeve layer 52 provided can increase the friction between the auxiliary drive roller 5 and the pipe fitting, and the oil holes 53 can prevent the formation of an oil film on the surface of the auxiliary drive roller 5, resulting in a decrease in friction, and finally ensuring the driving effect of the auxiliary drive roller 5.

[0040] As Figure 4 shown in the figure, the roller drive mechanism 6 includes a drive motor 61, a drive wheel 62 and a driven wheel 63. The drive wheel 62 is fixedly connected to the output shaft of the drive motor 61. The driven wheel 63 is fixedly connected to the ends of the oiling roller 2 and the auxiliary drive roller 5. The drive wheel 62 and the driven wheel 63 are drivingly connected by a drive belt 64. With the above structural form, when the drive motor 61 works to drive the drive wheel 62 to rotate, and through the driving action of the drive belt 64, the driven wheel 63 is driven to rotate, and finally the oiling roller 2 and the auxiliary drive roller 5 are driven to rotate.

[0041] As Figure 1 shown in the figure, an oil storage tank 11 is provided in the oil storage pool 1. The oil storage tank 11 stores oil. When the oil storage tank 11 is full of oil and the liquid level height does not exceed the horizontal plane where the central axis of the oiling roller 2 is located, with the above structural form, when the oiling roller 2 rotates, it can take out the oil adhering to its surface and brush it onto the surface of the pipe fitting.

[0042] In addition, protective cover plates 12 are provided on both sides of the oil storage pool 1, and the protective cover plates 12 can completely cover the linkage member 7. With the above structural form, the protective cover plates 12 can protect the linkage member 7 and prevent external foreign objects from falling on the linkage member 7 and causing damage to its work.

[0043] The working principle and working process of the present utility model:

[0044] The rotation of the two oiling rollers 2 can drive the pipe fitting installed therebetween to rotate. At the same time, part of the oiling roller 2 is located in the oil storage pool 1. Therefore, when it rotates, it can take out the oil and evenly brush it on the surface of the pipe fitting. Finally, while rotating the pipe fitting, the whole pipe fitting is oiled, which can greatly improve the oiling efficiency;

[0045] In addition, in order to prevent insufficient friction between the oiling roller 2 and the pipe fitting caused by the oil fluid, resulting in the slipping of the pipe fitting, during oiling, the hydraulic cylinder 3 can drive the movable frame 4 to lower, so that the auxiliary driving roller 5 presses on the upper side of the pipe fitting and drives it to rotate simultaneously, thereby significantly increasing the driving force received by the pipe fitting, enabling it to rotate continuously without slipping.

[0046] Finally, it should be noted that: Obviously, the above embodiments are merely examples given for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
