Description

Technical Field

[0001] The present invention relates to oilfield industrial equipment, and in particular to a production line for winding glue on sucker rods. Background Art

[0002] Sucker rods are important oil production equipment in current oilfield production, and are collectively referred to as the "three pumping" equipment together with sucker pumps and pumping units. With the exploitation of oilfields, the complexity of oil wells has increased day by day, and various inclined wells, horizontal wells, heavy oil wells, scale-containing wells, wax-containing wells, and combined oil wells with the above situations have become the norm in oilfield wells. Operating in these environments will cause the sucker rods to bend, eccentric wear, blockage, etc., seriously affecting the normal use of the sucker rods and shortening the service life of the sucker rods. Therefore, in these oil wells, centralizers, anti-eccentric wear devices, etc. need to be fixedly installed on the rod body of the sucker rod to prevent the rod body from bending and eccentric wear, or a wax scraper needs to be installed to scrape the wax scale on the inner wall of the tubing. The application of centralizing and wax scraping sucker rods is increasing day by day. Before the processing of the centralizer and the wax scraper, certain reinforcement measures need to be taken on the rod body to avoid the sliding and falling off of the centralizer or the wax scraper, resulting in product failure.

[0003] Applying and drying epoxy resin glue on the surface of the sucker rod body is an important measure for strengthening the centralizer and the wax scraper on the rod body at present. Applying epoxy resin glue on the surface of the sucker rod body is called the glue winding process in the industry. The prior art CN215283366 U discloses an automatic glue winding device for sucker rods. When this device is used, it is necessary to manually load and clamp the sucker rod, and use a motor to drive the sucker rod to rotate, so that the tape is wound on the surface of the sucker rod to achieve the effect of automatic glue winding, and finally manually unload the material. Although the disclosed patent describes glue winding for sucker rods, the tape wound is not epoxy resin glue, and the loading and unloading of the sucker rods are both manual operations, with a relatively large labor intensity. Currently, the glue winding process on the sucker rod body is relatively cumbersome, mainly manual operation, which requires manual holding of the rod body for loading and unloading, with a large labor intensity and low processing efficiency. Moreover, only single sucker rods are operated during loading and unloading, and the efficiency is significantly low. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present invention are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of protection of the claims.

[0021] As Figures 1 to 3 shown, the sucker rod rubber winding production line includes a loading rack 1. A rubber winding platform 2 is correspondingly installed on the discharging side of the loading rack 1. A plurality of double-station rubber winding devices 3 are arranged along the axis direction of the sucker rod 6 on the rubber winding platform 2. The double-station rubber winding device 3 includes an installation base 31. A lateral adjustment device is provided between the installation base 31 and the rubber winding platform 2. A rod driving device is installed on the installation base 31. There is a rubber winding station respectively in front of and behind the rod driving device. A rod loading device corresponding to the discharging side of the loading rack 1 is provided on one side of the rod driving device. A double-rod feeding device is correspondingly installed between the rod loading device and the rod driving device. A rod discharging device is provided on the other side of the rod driving device. A discharging guiding device 4 corresponding to the rod discharging device is provided on the discharging side of the rubber winding platform 2. A discharging rack 5 is correspondingly provided on the discharging side of the discharging guiding device 4.

[0022] Before rubber winding, several sucker rods 6 are placed on the loading rack 1 and wait for the rubber winding operation. Since the sucker rod 6 is a slender rod, during the rubber winding operation, a plurality of double-station rubber winding devices 3 act synchronously to cooperate with multi-point support for the sucker rod 6 to realize automatic loading, automatic rotation, and automatic unloading of the sucker rod 6. Each action of the double-station rubber winding device 3 is as follows: First, the rod loading device acts first, loading two sucker rods 6 on the loading rack 1 at one time. The two sucker rods 6 roll down along the rod loading device to above the rod driving device, and then cooperate with the double-rod feeding device to separate the two sucker rods 6 and guide them to the two rubber winding stations respectively. At this time, the rod driving device acts to drive the two sucker rods 6 at the two rubber winding stations to rotate respectively. During the rotation of the sucker rod 6, manual rubber winding operation of epoxy resin glue is carried out. The rubber winding position is operated by the worker at a certain section of the sucker rod 6 according to actual needs, and the rubber winding position varies according to the market or the product. After the rubber winding is completed and dried, the rod discharging device acts to lift the two sucker rods 6 and roll them down obliquely to the discharging guiding device 4, and finally the discharging guiding device 4 guides them to the discharging rack 5.

[0023] This wrapping gum production line can realize the automatic feeding and discharging of the sucker rod 6. During the wrapping gum operation, manual wrapping is adopted to avoid the disadvantage of glue blockage existing in automatic wrapping due to easy solidification. In the whole production line, only the wrapping gum step is manually operated. Compared with the completely manual operation in the prior art, the labor intensity is significantly reduced, and the processing efficiency can be effectively improved. At the same time, when this wrapping gum production line is working, two sucker rods 6 move to two wrapping gum stations respectively through a one-time feeding step, and then rotate and wait for wrapping gum at the two wrapping gum stations respectively. After wrapping gum, the two sucker rods 6 are discharged at one time. During this process, due to the simultaneous setting of two wrapping gum stations and the one-time feeding and discharging of two sucker rods 6, the feeding and discharging time can be greatly shortened, the continuity of the wrapping gum operation can be improved, the degree of automation is relatively high, and the processing efficiency is relatively high. And the structural design of the double-station wrapping gum device 3 is novel and the layout is reasonable, providing a relatively prominent innovative structure for the continuous and automatic production of the sucker rod 6 wrapping gum operation, filling the blank of this industry.

[0024] See Figure 1 , the loading rack 1 includes a horizontal storage rack 11, and a horizontal support is provided at the top of the horizontal storage rack 11 for storing the sucker rods 6 to be cleaned. And on one side of the horizontal storage rack 11, there is an inclined feeding rack 12. A downward inclined support is provided at the top of the inclined feeding rack 12 for placing and feeding support of the sucker rods 6. Since the rod body of the sucker rod 6 is a cylinder, it can roll on the inclined support to realize automatic feeding. The wrapping gum platform 2 is installed on the discharging side of the inclined feeding rack 12, and the rod body feeding device corresponds to the discharging side of the inclined feeding rack 12, and can take down the two sucker rods 6 discharged from the discharging side of the inclined feeding rack 12.

[0025] Since the sucker rod 6 is a slender rod, a plurality of double-station wrapping gum devices 3 are required to cooperate to support at multiple positions of the sucker rod 6. And in order to meet the length requirements of various different sucker rods 6, it is necessary for the double-station wrapping gum device 3 to be horizontally slidably adjusted along the axial direction of the sucker rod 6 (also called the transverse direction of the wrapping gum platform 2). Therefore, the transverse adjustment device is provided. See Figure 2 , the transverse adjustment device includes a transverse guide rail 32 installed on the wrapping gum platform 2. The transverse guide rail 32 is parallel to the axial direction of the sucker rod 6. A transverse sliding seat 33 is fixed at the bottom end of the mounting base 31. The transverse sliding seat 33 is slidably installed on the transverse guide rail 32. Through the corresponding cooperation of the transverse sliding seat 33 and the transverse guide rail 32, a driving cylinder can be provided between the mounting base 31 and the wrapping gum platform 2, so as to realize automatic transverse position adjustment. At other positions on the wrapping gum platform 2 except the positions avoiding the double-station wrapping gum device 3, receiving cover plates are placed to receive the waste generated during wrapping gum.

[0026] See Figure 2 andFigure 3 The rod driving device includes a rod driving wheel 34 rotatably mounted on the mounting base 31, a rotating power device is connected between the rod driving wheel 34 and the mounting base 31, and a rod supporting wheel 35 is rotatably mounted on the axis of the rod driving wheel 34 in front and back, and the rod supporting wheel 35 is rotatably mounted on the mounting base 31 through a bracket, and the rod driving wheel 34 is staggered with the two rod supporting wheels 35, and each corresponds to a glue wrapping station, that is, the rod driving wheel 34 is staggered with one of the rod supporting wheels 35 located on the front side to form a glue wrapping station, and is staggered with the other rod supporting wheel 35 located on the rear side to form another glue wrapping station, and the two glue wrapping stations are parallel. The rotating power device includes a glue wrapping driving motor 36 mounted on the mounting base 31, and the output end of the glue wrapping driving motor 36 is connected to the rod driving wheel 34 through a sprocket and chain transmission. The glue wrapping driving motor 36 rotates, and drives the rod body driving wheel 34 to actively rotate through the sprocket and the chain, thereby driving the sucker rods 6 on the two glue wrapping stations to rotate. During the rotation of the sucker rods 6, the glue wrapping operation of epoxy resin glue is performed manually.

[0027] The rod feeding device includes a rod feeding cylinder 37 installed on the installation base 31. A rod receiving and supporting plate 38 is installed at the top of the rod feeding cylinder 37. The rod receiving and supporting plate 38 is located at the side of the rod driving device and corresponds to the two winding rubber stations. The top surface of the rod receiving and supporting plate 38 is provided with a rod feeding inclined surface that is inclined upward towards the feeding rack 1. One end of the feeding side of the rod feeding inclined surface is provided with a rod separating hook 39. The rod top hook corresponds to the discharging side of the feeding rack 1. One end of the discharging side of the rod feeding inclined surface is provided with a rod blocking block 310. The bottom end of the rod blocking block 310 is provided with a blocking block base. The blocking block base is adjustably installed on the rod receiving and supporting plate 38 through a long hole, and the horizontal position of the blocking block base can be freely adjusted according to the specification of the sucker rod 6. Herein, the rod separating hook 39 is used to separate two sucker rods 6 from the feeding rack 1 to achieve one-time feeding; the rod feeding inclined surface is used to guide the two sucker rods 6 to roll and feed; and the rod blocking block 310 serves as a limiting structure to prevent the two sucker rods 6 from rolling excessively. During feeding, the cylinder rod of the rod feeding cylinder 37 extends to drive the rod receiving and supporting plate 38 to move upward. The rod separating hook 39 is exactly located directly below the two sucker rods 6 at the discharging side of the upper feeding rack 1 above. The rod separating hook 39 can separate the two sucker rods 6 on the feeding rack 1 from other sucker rods 6. As the rod receiving and supporting plate 38 continues to rise, until the two sucker rods 6 completely contact the rod feeding inclined surface, and then roll downward along the rod feeding inclined surface and stop after rolling to the rod blocking block 310. At this time, the two sucker rods 6 are arranged in contact front and back. As the rod receiving and supporting plate 38 continues to descend, the double-rod separating device will separate the two contacting sucker rods 6. See Figure 3 .

[0028] The rod feeding inclined surface includes a rod receiving inclined surface 311 near the feeding side. The discharging end of the rod receiving inclined surface 311 is provided with a rod separating inclined surface 312. The rod separating inclined surface 312 corresponds to the double-rod separating device. The inclination angle of the rod separating inclined surface 312 is smaller than the inclination angle of the rod receiving inclined surface 311. The inclination angle of the rod receiving inclined surface 311 is larger to achieve the rapid rolling of the two sucker rods 6, while the inclination angle of the rod separating inclined surface 312 is smaller. On the one hand, it can achieve the downward rolling of the sucker rod 6, and on the other hand, the height difference between the two sucker rods 6 is smaller, which does not affect the subsequent separating operation.

[0029] The double-rod feeding device includes a double-rod feeding base, which is adjustably installed on the installation base 31 through long holes. A double-rod feeding block 313 is provided at the top of the double-rod feeding base. The horizontal position of the double-rod feeding block 313 can be freely adjusted according to the specifications of the sucker rods 6 to ensure accurate feeding. A double-rod feeding edge 314 is provided at the top of the double-rod feeding block 313. On the front and rear sides of the double-rod feeding edge 314, there are respectively provided feeding guiding inclined surfaces 315 that are inclined downward; the double-rod feeding edge 314 corresponds to the axis of the rod driving wheel 34, and the top of the double-rod feeding edge 314 is higher than the top surface of the rod driving wheel 34. As the rod feeding cylinder 37 continues to shorten, it drives the rod receiving tray 38 and the two sucker rods 6 thereon to move downward. When the two sucker rods 6 contact the double-rod feeding block 313, when the rod receiving tray 38 continues to move downward, the double-rod feeding edge 314 pushes open the two sucker rods 6 to separate the two sucker rods 6. The two sucker rods 6 respectively roll forward and backward along the feeding guiding inclined surfaces 315, and then the two sucker rods 6 respectively roll forward and backward along the outer circumferential surface of the rod driving wheel 34 until the two sucker rods 6 are respectively stuck at the front rubber winding station and the rear rubber winding station and stop, completing the feeding process of the two sucker rods 6. See Figure 3 。

[0030] The rod discharging device includes a rod discharging cylinder 316 installed on the installation base 31. A rod discharging tray 317 is installed at the top of the rod discharging cylinder 316. The rod discharging tray 317 is located at the side of the rod driving device and corresponds to the two rubber winding stations. On the top surface of the rod discharging tray 317, there is provided a rod discharging inclined surface 318 that is inclined downward towards the discharging guiding device 4. After the rubber winding is completed, the cylinder body of the rod discharging cylinder 316 extends, driving the rod discharging tray 317 to move upward. During the upward movement, the two sucker rods 6 are lifted and roll downward along the rod discharging inclined surface 318, and the two sucker rods 6 roll onto the discharging guiding device 4.

[0031] The blanking guiding device 4 includes a blanking guiding frame 41 arranged between the blanking rack 5 and the rubber winding platform 2. The top of the blanking guiding frame 41 corresponds to the rod blanking device. The upper part of the blanking guiding frame 41 is hinged on the rubber winding platform 2. A guiding frame driving cylinder 42 for driving the blanking guiding frame 41 to change the inclination angle is further arranged between the blanking guiding frame 41 and the rubber winding platform 2. After the rubber winding is completed, the blanking guiding driving cylinder cooperates to extend, driving the blanking guiding frame 41 to incline towards the blanking rack 5. The sucker rod 6 rolling onto the blanking guiding frame 41 rolls down along the inclined surface onto the blanking rack 5, completing the automatic blanking of the sucker rod 6. After the blanking is completed, the guiding frame driving cylinder 42 retracts, driving the blanking guiding frame 41 to vertically move downward for avoidance, facilitating the rubber winding operation of the worker on the sucker rod 6 at the rubber winding station.

[0032] The blanking rack 5, also known as the storage rack, can adopt a layered structure for multi-layer storage to increase the storage capacity.
