Description

Technical Field

[0001] The invention mainly relates to the technical field of oil pump monitoring, and in particular to a belt monitoring device of an oil pump. Background Art

[0002] The oil pump is a kind of machine equipment for oil extraction, commonly known as "kowtow machine". The oil pump is the most important lifting equipment in the rod pumping system. During the use of the oil pump, the drive motor will drive the oil pump through the transmission belt. If the belt operates at high load for a long time, cracks will appear on the surface, which will cause the belt to wear and break, thus causing damage to the oil pump.

[0003] Therefore, when the existing oil pump is in use, a monitoring device is usually set at the transmission belt to monitor the wear state of the transmission belt. The existing monitoring device usually uses a camera for monitoring, which can only monitor the cracks on the belt surface. If cracks appear inside the belt and have not extended to the surface, this method cannot be monitored. However, when the internal cracks extend to the surface of the transmission belt, the transmission belt may break. At this time, it is too late to shut down the machine for maintenance. Moreover, the existing monitoring device can only monitor the cracks in the transmission belt, and cannot mark the places where the cracks appear in the transmission belt. This will result in that when the oil pump is shut down for maintenance, the staff will need to check the cracks themselves, which will affect work efficiency. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a belt monitoring device for an oil pump, which is used to solve the technical problem mentioned in the above background technology that the existing monitoring device cannot monitor the cracks inside the transmission belt, and the existing monitoring device cannot mark the places where cracks appear in the transmission belt.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A belt monitoring device for an oil pump comprises an oil pump body, a support shell is arranged on the oil pump body, a transmission belt is arranged inside the support shell, an extrusion roller for maintaining the extrusion fit of the transmission belt is arranged inside the support shell, a marking component for monitoring and marking cracks on the transmission belt and giving an audible reminder is arranged on the extrusion roller, and a compensation component for replenishing the marking component detached from the extrusion roller is arranged on the extrusion roller.

[0007] Preferably, a rotating shaft and a supporting shaft are provided inside the supporting shell, and squeezing rollers are provided on the rotating shaft and the supporting shaft, and the two squeezing rollers are attached to the upper and lower sides of the transmission belt.

[0008] Preferably, a motor is provided on the support shell, an output end of the motor is connected to one end of the rotating shaft, transmission wheels are provided on the rotating shaft and the support shaft, and tension belts are sleeved on the two transmission wheels.

[0009] Preferably, the extrusion roller is provided with a plug-in slot, the compensation component comprises a telescopic sleeve rod, the telescopic sleeve rod is arranged inside the plug-in slot, a first spring is sleeved on the telescopic sleeve rod, and a pushing plate for pressing against two sides of the compensation component is provided at one end of the telescopic sleeve rod.

[0010] Preferably, the marking assembly comprises an insertion rod, the insertion rod is arranged inside the insertion slot, a telescopic rod is inserted into the insertion rod, and a second spring is sleeved on the telescopic rod.

[0011] Preferably, a top block is provided on the telescopic rod, a magnet is provided above the top block, the top block and the magnet are arranged on the extrusion roller in a circumferential array and a transverse array, and the top block and the magnet fit together to form a cylindrical shape as a whole.

[0012] Preferably, a piston is provided at one end of the telescopic rod away from the top block, and the piston is inserted into the inner cavity of the insertion rod.

[0013] Preferably, an air outlet and an air inlet are provided on the insertion rod, a whistle is provided on the insertion rod, and the whistle is arranged at the air outlet.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: a layer of marking components is covered on the outer sides of the upper and lower squeezing rollers, and the marking components are in contact with the belt. When cracks appear on the belt, whether it is the upper surface, the lower surface or the inside of the belt, there is a gap where the cracks appear on the belt, and that part of the belt is relatively weak, and the marking components on both sides will be pushed to move inward toward each other, and because the uppermost layer of the marking components is provided with magnets, when the marking components on both sides are pushed inward, the spacing between the relative marking components on both sides becomes smaller, and the suction force generated by the magnets provided on the two marking components becomes larger, so that the marking components on both sides will be attracted to fall off from the squeezing rollers and adsorbed on both sides of the belt, thereby marking the places where cracks appear on the belt, and because the marking components are on the belt, the marking components can not only monitor the places where cracks appear on the belt, but also mark the specific positions of the cracks.

[0015] When both sides of the marking component are adsorbed on the transmission belt, the marking component on the inside will move with the transmission belt and come into contact with the pulley. When the marking component moves to the pulley, the pulley will compress the marking component. At this time, the marking component on the inside will push the gas inside the inner cavity of the plug rod to the air outlet for discharge. At this time, the whistle set at the air outlet will make a sound, which serves to remind the staff that there are cracks on the belt, so there is no need for the staff to keep an eye on the belt all the time.

[0016] When the marking component marks a crack on the belt, a notch will appear in the marking component on the extrusion roller. Because the belt will not stop running immediately after being marked, and there is no guarantee that there will be only one crack on the belt, when the marking component is detached from the extrusion roller, the compensation component in the same slot will push the marking components inside this row of slots from both sides to move the marking components on both sides toward the notch, and the spare marking components set inside this row of slots will fill the notch. In this way, after the marking component marks one crack on the belt, the belt continues to work, and the marking component can also mark subsequent cracks on the belt to prevent gaps from causing loopholes in the belt marking by the marking component.

[0017] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] Please refer to the attached Figure 1-Figure 8A belt monitoring device for an oil pump comprises an oil pump body 1, a support shell 2 is arranged on the oil pump body 1, a transmission belt 3 is arranged inside the support shell 2, a squeezing roller 4 for maintaining the squeezing and fitting of the transmission belt 3 is arranged inside the support shell 2, a marking component 6 for monitoring and marking cracks on the transmission belt 3 and giving a sound reminder is arranged on the squeezing roller 4, and a compensation component 5 for replenishing the marking component 6 detached from the squeezing roller 4 is arranged on the squeezing roller 4.

[0042] The specific operation process of the present invention is as follows: when the oil pump body 1 is working, the transmission belt 3 works to transmit, and at this time, the two squeezing rollers 4 are driven to work. The marking components 6 on the two squeezing rollers 4 are attached to the upper and lower sides of the transmission belt 3, and the two squeezing rollers 4 rotate relative to each other. When a crack appears on the transmission belt 3, no matter whether the crack is on the upper surface, the lower surface or the inside of the transmission belt 3, as long as the crack is large enough to cause the transmission belt 3 to break, when the crack of the transmission belt 3 moves between the upper and lower squeezing rollers 4, the marking component 6 on the squeezing roller 4 will press on the crack, and the marking components 6 on both sides will adsorb and mark the crack of the transmission belt 3, and the marking component 6 moves with the transmission belt 3. When the marking component 6 moves to the pulley and is squeezed, the marking component 6 will make a sound to remind, and a pair of marking components 6 on the two squeezing rollers 4 will be separated and a gap will be generated. At this time, the compensation component 5 will push this row of marking components 6, and push the row of spare marking components 6 on the squeezing roller 4 to supplement the gap, so that the transmission belt 3 continues to work. If cracks appear in other places, the marking component 6 can continue to monitor and mark.

[0043] Please refer to Figure 4 and Figure 5 A rotating shaft 8 and a supporting shaft 9 are arranged inside the supporting shell 2, and squeezing rollers 4 are arranged on the rotating shaft 8 and the supporting shaft 9. The two squeezing rollers 4 are attached to the upper and lower sides of the transmission belt 3. A motor 7 is arranged on the supporting shell 2, and the output end of the motor 7 is connected to one end of the rotating shaft 8. Transmission wheels 10 are arranged on the rotating shaft 8 and the supporting shaft 9, and tensioning belts 11 are sleeved on the two transmission wheels 10.

[0044] Start the motor 7, which drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the support shaft 9 to rotate relative to each other through the tensioning belt 11 and the transmission wheel 10. At this time, the rotating shaft 8 and the support shaft 9 drive the upper and lower squeezing rollers 4 to rotate relative to each other to assist the middle transmission belt 3 to pass through.

[0045] Please refer to Figure 5 and Figure 6A plug-in slot 54 is provided on the extrusion roller 4, and the compensation component 5 includes a telescopic sleeve rod 51, which is arranged inside the plug-in slot 54, and a first spring 52 is sleeved on the telescopic sleeve rod 51. A pushing plate 53 for supporting both sides of the marking component 6 is provided at one end of the telescopic sleeve rod 51.

[0046] A plurality of groups of plug-in slots 54 are provided on the squeezing roller 4 in a circular array, and a compensation component 5 is provided on the left and right sides of each plug-in slot 54. The compensation component 5 is pressed against the two sides of a group of compensation components 5 provided inside each plug-in slot 54 by the first spring 52 to push the push plate 53. The telescopic sleeve 51 is used to limit the push plate 53 to prevent the push plate 53 from offset and flipping when pushing the compensation component 5. Not all of the compensation components 5 inside each plug-in slot 54 are in contact with the transmission belt 3, but a part of them is in a standby state. The marking components 6 in these standby states can be limited and compressed by the shell to prevent the marking components 6 on both sides from extending and adsorbing each other. When the marking component 6 in contact with the transmission belt 3 is adsorbed on the transmission belt 3 and separated from the squeezing roller 4, a gap will appear in the marking component 6 on the squeezing roller 4. At this time, the spare marking component 6 is pushed toward the gap by the push plates 53 provided on both sides to supplement the gap with the marking component 6.

[0047] Please refer to Figure 7 and Figure 8 The marking assembly 6 includes an insertion rod 61, which is arranged inside the insertion groove 54. A telescopic rod 62 is inserted into the insertion rod 61, and a second spring 65 is sleeved on the telescopic rod 62. A top block 63 is arranged on the telescopic rod 62, and a magnet 64 is arranged above the top block 63. The top block 63 and the magnet 64 are arranged in a circular array and a transverse array on the extrusion roller 4, and the top block 63 and the magnet 64 fit each other to form a cylindrical shape as a whole.

[0048] The compensation component 5 is arranged on a circle of the squeezing roller 4, and the adjacent top blocks 63 and magnets 64 of the compensation component 5 are attached to each other to form a cylindrical shape. The magnet 64 is arranged in the middle above the top block 63 to prevent the adjacent magnets 64 from being adsorbed together. The top block 63 will separate the adjacent magnets 64 from each other. The bottom of the plug-in slot 54 is an arc shape with an opening formed on the top. The plug-in slot 54 has a certain clamping force on the plug rod 61, and the plug rod 61 can move along the plug-in slot 54 under the action of the pushing plate 53. The clamping force of the plug-in slot 54 on the plug rod 61 can ensure the balance state of the magnets 64 on both sides of the intact transmission belt 3 (referring to when the transmission belt 3 is intact, the magnets 64 are attached to both sides of the transmission belt 3, and the magnets 64 on both sides will generate suction between each other to make the magnets 64 on both sides adsorb to each other, but this At this time, since the transmission belt 3 is intact, the thickness of the belt makes the suction force between the magnets 64 on both sides not so great, which is not enough to break free from the clamping force of the plug-in slot 54 on the plug rod 61). When a crack appears on the transmission belt 3 and allows the magnet 64 on one side to move forward, the clamping force is less than the suction force between the magnets 64. The magnets 64 on both sides of the transmission belt 3 will be adsorbed on the transmission belt 3 and carried away by the transmission belt 3. A part of the compensation component 5 is attached to the transmission belt 3, and a shell is provided at the part of the extrusion roller 4 that is not in contact with the transmission belt 3. The shell wraps the spare part of the compensation component 5 inside. The shell is used to wrap the spare part of the magnet 64 and the top block 63 inside in a compressed state to prevent this part of the magnet 64 and the top block 63 from being pushed upward by the second spring 65, causing the spare marking components 6 on both sides to be adsorbed together.

[0049] Please refer to Figure 7 and Figure 8 A piston 66 is provided at one end of the telescopic rod 62 away from the top block 63, and the piston 66 is inserted into the inner cavity of the insertion rod 61. The insertion rod 61 is provided with an air outlet 67 and an air inlet 69. A whistle 68 is provided on the insertion rod 61, and the whistle 68 is set at the air outlet 67.

[0050] When the compensation component 5 is adsorbed on the transmission belt 3 and moves with the transmission belt 3, the transmission belt 3 drives the compensation component 5 to move to the pulley, the pulley and the transmission belt 3 will compress the insertion rod 61 and the telescopic rod 62, and the piston 66 on the telescopic rod 62 moves down along the inside of the insertion rod 61, squeezing the air inside the insertion rod 61 out from the air outlet 67, and the air flows to the whistle 68 to make a sound for prompting. When the compensation component 5 moves away from the pulley, the second spring 65 will push the top block 63 upward again, and the telescopic rod 62 will also be pulled out from the inside of the insertion rod 61. At this time, the piston 66 moves upward to draw air into the inner cavity of the insertion rod 61 from the air inlet 69.

[0051] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
