Description

Technical Field

[0001] The present invention belongs to the technical field of submerged pump cross-section grinding, and particularly relates to a grinding device for the cross-section of a submerged pump. Background Art

[0002] A submerged pump is a device commonly used for pumping liquids, and is widely used in industries such as chemical engineering, petroleum, metallurgy, and electric power. Its design is mainly for providing efficient liquid transportation capacity in occasions where the depth of liquid extraction is relatively large or the space is narrow. The structure of a submerged pump generally includes a pump body, a pump shaft, an impeller, a sealing device, etc. Different from traditional vertical pumps and horizontal pumps, the pump body part of a submerged pump is usually submerged in the liquid, and its suction port is located at the bottom of the pump body. Therefore, it can effectively solve the suction problem when the liquid level is relatively low. The cross-section structure design of a submerged pump is crucial, and it is usually necessary to ensure the stability and durability of its various components during operation, especially the sealing part, which can prevent liquid leakage and ensure the long-term efficient operation of the pump.

[0003] The cross-section of a submerged pump is crucial during use and must undergo relevant processing to meet the use requirements. When the existing grinding device for the cross-section of a submerged pump is grinding, it usually requires an operator to hold it by hand individually for grinding, resulting in low grinding efficiency and poor stability, thereby reducing the processing speed of the submerged pump. In addition, the specifications of submerged pumps vary in length, resulting in poor balance control during the grinding process by the operator, and thus uneven grinding, which affects the quality of the submerged pump. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a grinding device for the cross-section of a submerged pump.

[0005] The technical solution adopted to solve the above technical problem is: a grinding device for the cross-section of a submerged pump, including a main body and a pump body. A clamping mechanism is installed on the outer wall of the pump body for clamping the pump body to keep it stable; The clamping mechanism includes a plurality of L-shaped rods. A connecting rod is rotatably connected to one end of each of the plurality of L-shaped rods away from the pump body, and an arc-shaped clamp is fixedly connected to one end of each of the plurality of L-shaped rods close to the pump body. By lifting and lowering the plurality of connecting rods to drive the corresponding L-shaped rods to rotate, the plurality of arc-shaped clamps clamp the pump body. A locking mechanism is installed at the bottom of the plurality of connecting rods for driving the L-shaped rods to rotate and lock the pump body; The locking mechanism includes two square plates and corresponding staggered serrated rings. A limiting column is slidably connected between the two serrated rings. A support column is fixedly connected to the top of the limiting column, and a trapezoidal block is fixedly connected to the top of the support column. Brackets are installed at both ends of the two square plates away from the support column, and a rectangular plate is fixed to the top of the bracket away from the square plate. A rectangular groove is opened inside the rectangular plate for limiting the trapezoidal block to control the lifting height of the plurality of connecting rods.

[0006] A cabinet door is installed at one end of the main body surface away from the clamping mechanism, and an inner built-in plate is fixedly connected to the inner wall of the main body.

[0007] Furthermore, an alternating mechanism is installed on the top of the built-in plate. The alternating mechanism includes an equilateral triangle chassis, and an equilateral triangle chute is provided on the outer side of the top of the equilateral triangle chassis. A circular groove is provided on the inner section of the equilateral triangle chute. Three oblong gears are slidably connected inside the equilateral triangle chute and the circular groove. Two limiting wheels are rotatably connected to the bottom of each oblong gear. The limiting wheel on the side of the oblong gear close to the apex angle of the equilateral triangle chassis reaches the corner groove of the equilateral triangle chassis. Then, the limiting wheel on the side of the oblong gear away from the apex angle of the equilateral triangle chassis is squeezed into the circular groove by the length of the oblong gear, realizing the direction conversion of the oblong gear. Three circular gears are meshed with the outer walls of the three oblong gears. A first motor connected to the bottom of the circular gear is installed at the bottom of the built-in plate, and driving the circular gear to rotate drives the pump bodies on the three oblong gears to change positions.

[0008] Through the above technical solution, during use, after opening the cabinet door, the pump bodies are sequentially placed into the main body, and then the alternating mechanism is used to transport the pump bodies to achieve grinding. At the same time, the position can be changed during the grinding process to ensure sufficient grinding of the pump bodies. In addition, the alternating mechanism is used in cooperation with other mechanisms. When the pump bodies enter and rotate one circle, they enter the inner side. When they are turned to the outer side again, they are taken off, thereby ensuring the grinding time of the pump bodies. Specifically, start the first motor, and its output shaft drives the circular gear to rotate. Subsequently, based on the meshing of the three oblong gears with the circular gear, the three oblong gears will be driven to rotate. First, they move in the equilateral triangle chute. When the limiting wheel on the side of the oblong gear bottom close to the equilateral triangle chassis first enters the apex angle of the equilateral triangle chute, based on the length of the oblong gear itself, as it rotates, the limiting wheel on the side of the oblong gear bottom away from the equilateral triangle chassis will slide along the circular groove, thereby realizing the change of the direction and position of the oblong gear, so as to realize the mutual rotation change of the three apex angles. It should be understood that when the pump bodies are placed, the side of the pump bodies close to the cabinet door, after passing through the three apex angles, the pump bodies are rotated to the side away from the cabinet door. When rotating one more circle, the pump bodies can be taken out after being fully ground.

[0009] Furthermore, two slope extrusion blocks are installed at one end of the surface of the built-in plate away from the pump bodies. A fitting frame located between the brackets is fixedly connected to the bottom of one of the square plates. A spring is installed between the top of the other square plate and the rectangular plate. By contacting the extrusion block to squeeze the fitting frame upward, the two square plates and the staggered serrated ring move upward. Opposite-direction fixing plates are installed on the tops of the three oblong gears. The tops of the multiple fixing plates are fixedly connected to the brackets and are slidably connected to the fitting frame inside.

[0010] Through the above technical solution, after the pump body is placed, it is first necessary to ensure the stability of the pump body before grinding. At this time, the locking mechanism is required to fix it to ensure the stability of grinding and ensure that there is no offset phenomenon. At the same time, during the grinding process, on the basis of ensuring the grinding time, it is also convenient for the taking and placing of the pump body. Specifically, as the oval gear rotates, the fixing plate located on the oval gear will pass one of the extrusion blocks on the surface of the built-in plate. At this time, the fitting frame will extend upward along the sloped extrusion block, and then the fitting frame will drive the two square plates to move upward along the bracket, thereby squeezing the spring. As the extrusion continues, when the part composed of the limit post, the support post, and the trapezoidal block extends upward until it is squeezed, the limit post rotates on the two staggered sawtooth rings. It should be understood that when the extrusion of the limit post reaches the top sawtooth ring from the bottom sawtooth ring, and the two sawtooth rings are staggered, rotation occurs during the movement process, and then the trapezoidal block rotates accordingly. At the same time, it is limited by the rectangular groove inside the rectangular plate and then opens to facilitate the placement of the pump body. In addition, when the trapezoidal block rises to the limit and rotates, it will rebound a certain distance to ensure subsequent tightening and extrusion.

[0011] Further, a circular bottom frame is installed at the bottom of the pump body. A support plate is installed at the junction of the outer side of the circular bottom frame and the corresponding L-shaped rod. A plurality of fitting clips are installed at the joint of the outer wall of the circular bottom frame and the outer wall of the pump body. A plurality of connecting plates are installed between the two square plates, and the plurality of connecting plates are respectively rotatably connected to one end of the corresponding connecting rod.

[0012] Through the above technical solution, as the locking mechanism operates, it drives the clamping mechanism to open and receive the placement of the pump body. Specifically, as the two square plates move upward, it will drive the connecting rods on the plurality of connecting plates to move upward. At this time, under the rotational support of the plurality of support plates, the arc-shaped clips at one end of the plurality of L-shaped rods close to the pump body will open to the side away from the circular bottom frame. Subsequently, under the stabilization of the plurality of fitting clips, the pump body is placed. Then, when the oval gear continues to rotate, the fitting frame will touch another extrusion block and be squeezed, and then the above steps are repeated. The difference is that as the two columns on the outer side of the limit post rotate on the staggered sawtooth rings, the trapezoidal block is disengaged from the rectangular groove. Under the connection of the spring, the two square plates move downward, thereby clamping the pump body, and then waiting for grinding.

[0013] Further, a grinding mechanism is installed at the top of the main body. The grinding mechanism includes a hydraulic cylinder. A fixed head is installed at the piston end of the hydraulic cylinder close to the pump body. The grinding height is controlled by driving the fixed head through the telescopic movement of the hydraulic cylinder. A second motor is installed inside the fixed head. The bottom output end of the second motor is fixed with a drive shaft. A grinding disc is installed at the bottom of the drive shaft away from the second motor. The grinding disc is driven by the rotation of the drive shaft of the second motor to synchronously grind a plurality of pump bodies.

[0014] Through the above technical solution, after the pump body is placed, the grinding mechanism is used to grind it. Specifically, the hydraulic cylinder is started, and its piston end drives the second motor on the fixed head to move downward to determine the grinding height. Then, the second motor is started to drive the grinding disc on the drive shaft to rotate, realizing the grinding of the cross-section of the submersible pump.

[0015] The beneficial effects of the present invention are as follows: (1) By designing the alternating mechanism, the locking mechanism and the clamping mechanism, when the grinding device is working, the submersible pump can be quickly placed and then quickly clamped for grinding, thereby accelerating the grinding efficiency of the cross-section of the submersible pump. At the same time, multiple submersible pumps are alternately ground, and on the basis of ensuring the grinding quality, a fixed grinding cycle state is realized, thus ensuring the working performance of the grinding device; (2) By designing the alternating mechanism, when the cross-section of the submersible pump is ground, multiple submersible pumps can be ground synchronously, and while multiple submersible pumps are alternating, it is ensured that a single submersible pump is ground in the grinding device for a specified time, thereby ensuring the grinding quality. After cycling, the submersible pump is taken off, improving the working performance of the grinding device; (3) By designing the locking mechanism and the clamping mechanism, the submersible pump is clamped and relaxed by the external extrusion during the flow-type grinding, and at the same time, the position is changed for grinding, so that the submersible pump can switch positions for grinding during grinding, and at the same time, the stability during grinding is ensured, avoiding the inclination of the submersible pump, thereby improving the grinding quality of the submersible pump.

Detailed implementation manners

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] As Figures 1-10As shown in the figure, a grinding device for the cross-section of a submersible pump in this embodiment includes a main body 11 and a pump body 14. A cabinet door 12 is installed at one end of the surface of the main body 11 away from the clamping mechanism 4. An inner built-in plate 13 is fixedly connected to the inner wall of the main body 11. An alternating mechanism 2 is installed on the top of the inner built-in plate 13. The alternating mechanism 2 includes an equilateral triangle chassis 21, and an equilateral triangle chute 22 is provided on the outer side of the top of the equilateral triangle chassis 21. A circular groove 23 is provided on the inner section of the equilateral triangle chute 22. Three oblong gears 26 are slidably connected inside both the equilateral triangle chute 22 and the circular groove 23. Two limiting wheels 27 are rotatably connected to the bottom of each oblong gear 26. The limiting wheel 27 on one side of the oblong gear 26 close to the apex angle of the equilateral triangle chassis 21 reaches the angle groove of the equilateral triangle chassis 21. Then, the limiting wheel 27 on the side of the oblong gear 26 away from the apex angle of the equilateral triangle chassis 21 is squeezed into the circular groove 23 by the length of the oblong gear 26, realizing the direction conversion of the oblong gear 26. Three circular gears 25 are meshed with the outer walls of the three oblong gears 26. A first motor 24 connected to the bottom of the circular gear 25 is installed at the bottom of the inner built-in plate 13 to drive the circular gear 25 to rotate, driving the pump body 14 on the three oblong gears 26 to change positions. When in use, after opening the cabinet door 12, the pump body 14 is sequentially placed into the main body 11, and then the alternating mechanism 2 is used to transport the pump body 14 for grinding. At the same time, the position can be changed during the grinding process to ensure sufficient grinding of the pump body 14. In addition, the alternating mechanism 2 is used in cooperation with other mechanisms. When the pump body 14 enters and rotates one circle, it enters the inner side. When it is turned to the outer side again, it can be taken down, thereby ensuring the grinding time of the pump body 14. Specifically, start the first motor 24, and its output shaft drives the circular gear 25 to rotate. Then, based on the meshing of the three oblong gears 26 and the circular gear 25, the three oblong gears 26 will be driven to rotate. First, they move in the equilateral triangle chute 22. When the limiting wheel 27 on the side of the bottom of the oblong gear 26 close to the equilateral triangle chassis 21 first enters the apex angle of the equilateral triangle chute 22, based on the length of the oblong gear 26 itself, as it rotates, the limiting wheel 27 on the side of the bottom of the oblong gear 26 away from the equilateral triangle chassis 21 will slide along the circular groove 23, thereby realizing the change of the direction and position of the oblong gear 26, and thus realizing the mutual rotation change of the three apex angles. It should be understood that when the pump body 14 is placed, the side of the pump body 14 close to the cabinet door 12, after passing through the three apex angles, the pump body 14 is rotated to the side away from the cabinet door 12. When it rotates one more circle, the pump body 14 can be taken out after being fully ground.

[0020] As Figures 5-10As shown, a locking mechanism 3 is installed at the bottom of multiple connecting rods 42 for driving the L-shaped rod 44 to rotate and lock the pump body 14. The locking mechanism 3 includes two square plates 38 and corresponding staggered serrated rings 39. A limiting column 310 is slidably connected between the two serrated rings 39. A support column 35 is fixedly connected to the top of the limiting column 310. A trapezoidal block 311 is fixedly connected to the top of the support column 35. Brackets 33 are installed at both ends of the two square plates 38 away from the support column 35. A rectangular plate 34 is fixedly installed at the top of the bracket 33 away from the square plate 38. A rectangular groove 36 is provided inside the rectangular plate 34 for limiting the trapezoidal block 311 to control the lifting height of the multiple connecting rods 42. Two slope extrusion blocks 31 are installed at one end of the surface of the built-in plate 13 away from the pump body 14. A fitting frame 37 located between the brackets 33 is fixedly connected to the bottom of one of the square plates 38. A spring 312 is installed between the top of the other square plate 38 and the rectangular plate 34. By the contact extrusion block 31 squeezing the fitting frame 37 upward, the two square plates 38 and the staggered serrated rings 39 move upward. Opposite-direction fixing plates 32 are installed at the tops of the three oval gears 26. The tops of the multiple fixing plates 32 are fixedly connected to the brackets 33 and are slidably connected to the fitting frame 37 inside. After the pump body 14 is placed, it is first necessary to ensure the stability of the pump body 14 before grinding. At this time, the locking mechanism 3 is required to fix it to ensure the stability of grinding and at the same time ensure that no offset occurs. At the same time, during the grinding process, on the basis of ensuring the grinding time, it is also convenient for the loading and unloading of the pump body 14. Specifically, as the oval gear 26 rotates, at this time, the fixing plate 32 located on the oval gear 26 will pass by one of the extrusion blocks 31 on the surface of the built-in plate 13. At this time, the fitting frame 37 will extend upward along the sloped extrusion block 31. Furthermore, the fitting frame 37 will drive the two square plates 38 to move upward along the brackets 33, thereby squeezing the spring 312. As the extrusion continues, when the part composed of the limiting column 310, the support column 35, and the trapezoidal block 311 extends upward until it is squeezed, the limiting column 310 rotates on the two staggered serrated rings 39. It should be understood that when the extrusion of the limiting column 310 reaches the top serrated ring 39 from the bottom serrated ring 39, and the two serrated rings 39 are staggered, rotation occurs during the movement process. Furthermore, the trapezoidal block 311 rotates accordingly and is limited by the rectangular groove 36 inside the rectangular plate 34, and then opens up to facilitate the placement of the pump body 14. In addition, when the trapezoidal block 311 rises to the limit and rotates, it will rebound a certain distance to ensure subsequent tightening and extrusion.

[0021] As Figure 7 and Figure 9As shown, a clamping mechanism 4 is installed on the outer wall of the pump body 14 for clamping the pump body 14 to keep it stable. The clamping mechanism 4 includes a plurality of L-shaped rods 44. One end of each of the plurality of L-shaped rods 44 away from the pump body 14 is rotatably connected to a connecting rod 42. One end of each of the plurality of L-shaped rods 44 close to the pump body 14 is fixedly connected to an arc-shaped clamp 45. By lifting and lowering the plurality of connecting rods 42 to drive the corresponding L-shaped rods 44 to rotate, the plurality of arc-shaped clamps 45 can clamp the pump body 14. A circular bottom frame 47 is installed at the bottom of the pump body 14. A support plate 43 is installed at the junction of the outer side of the circular bottom frame 47 and the corresponding L-shaped rod 44. A plurality of fitting clamps 46 are installed at the joint where the outer wall of the circular bottom frame 47 fits the outer wall of the pump body 14. A plurality of connecting plates 41 are installed between the two square plates 38, and one end of each of the plurality of connecting plates 41 is rotatably connected to the corresponding connecting rod 42. As the locking mechanism 3 operates, the clamping mechanism 4 is driven to open to accommodate the placement of the pump body 14. Specifically, as the two square plates 38 move upward, the connecting rods 42 on the plurality of connecting plates 41 will be driven to move upward. At this time, under the rotational support of the plurality of support plates 43, the arc-shaped clamps 45 at one end of the plurality of L-shaped rods 44 close to the pump body 14 will open towards the side away from the circular bottom frame 47. Then, with the stabilization of the plurality of fitting clamps 46, the pump body 14 is placed in. Subsequently, when the long circular gear 26 continues to rotate, the fitting frame 37 will touch another extrusion block 31 and be extruded, and then the above steps are repeated. The difference is that as the two cylinders on the outer side of the limit post 310 rotate on the staggered sawtooth ring 39, the trapezoidal block 311 is separated from the rectangular groove 36. Under the connection of the spring 312, the two square plates 38 move downward, thereby clamping the pump body 14, and then waiting for grinding.

[0022] As Figure 3 As shown, a grinding mechanism 5 is installed on the top of the main body 11. The grinding mechanism 5 includes a hydraulic cylinder 51. A fixed head 52 is installed at the piston end of the hydraulic cylinder 51 close to the pump body 14. The telescopic movement of the hydraulic cylinder 51 drives the fixed head 52 to control the grinding height. A second motor 53 is installed inside the fixed head 52. A driving shaft 54 is fixed to the bottom output end of the second motor 53. A grinding disc 55 is installed at the bottom of the driving shaft 54 away from the second motor 53. The rotation of the driving shaft 54 of the second motor 53 drives the grinding disc 55 to synchronously grind a plurality of pump bodies 14. After the pump body 14 is placed, the grinding mechanism 5 is used to grind it at this time. Specifically, the hydraulic cylinder 51 is started, and its piston end drives the second motor 53 on the fixed head 52 to move downward to determine the grinding height. Then, the second motor 53 is started to drive the grinding disc 55 on the driving shaft 54 to rotate, realizing the grinding of the section of the submersible pump.

[0023] The working principle of this embodiment is as follows. When in use, after opening the cabinet door 12, the pump body 14 is sequentially placed into the main body 11. Subsequently, the first motor 24 is started, and its output shaft drives the circular gear 25 to rotate. Subsequently, on the basis of the meshing of the three oval gears 26 with the circular gear 25, the three oval gears 26 will be driven to rotate. First, they move in the equilateral triangular chute 22. When the limiting wheel 27 on the side of the bottom of the oval gear 26 close to the equilateral triangular chassis 21 first enters the vertex angle of the equilateral triangular chute 22, on the basis of the length of the oval gear 26 itself, with the rotation, the limiting wheel 27 on the side of the bottom of the oval gear 26 far from the equilateral triangular chassis 21 will slide along the circular groove 23, thereby realizing the change in the direction and position of the oval gear 26. With the rotation of the oval gear 26, at this time, the fixing plate 32 on the oval gear 26 will pass by one of the extrusion blocks 31 on the surface of the built-in plate 13. At this time, the fitting frame 37 will extend upward along the sloped extrusion block 31, and then the fitting frame 37 will drive the two square plates 38 to move upward along the support 33, thereby squeezing the spring 312. With the continuous progress of the extrusion, when the part composed of the limiting column 310, the support column 35, and the trapezoidal block 311 extends upward until it is squeezed, the limiting column 310 rotates on the two staggered serrated rings 39, and then the trapezoidal block 311 rotates accordingly. At the same time, it is limited by the rectangular groove 36 inside the rectangular plate 34, and then opens. With the upward movement of the two square plates 38, at this time, the connecting rods 42 on the multiple connecting plates 41 will be driven to move upward. At this time, under the rotational support of the multiple support plates 43, the arc-shaped clamps 45 at the ends of the multiple L-shaped rods 44 close to the pump body 14 will open toward the side away from the circular chassis 47. Subsequently, with the stabilization of the multiple fitting clamps 46, the pump body 14 is placed. Subsequently, when the oval gear 26 continues to rotate, the fitting frame 37 will touch another extrusion block 31 and be squeezed, and then the above steps are repeated. The difference is that as the two cylinders on the outside of the limiting column 310 rotate on the staggered serrated rings 39, the trapezoidal block 311 is disengaged from the rectangular groove 36. Under the connection of the spring 312, the two square plates 38 move downward, thereby clamping the pump body 14. Finally, the hydraulic cylinder 51 is started, and its piston end drives the second motor 53 on the fixed head 52 to move downward to determine the grinding height. Subsequently, the second motor 53 is started to drive the grinding disc 55 on the drive shaft 54 to rotate, realizing grinding while rotating.

[0024] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
