Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, and in particular to an intelligent lifting device for repairing a deep well pump. Background Art

[0002] As a kind of pumping equipment, deep well pumps are widely used in various fields, including explosion-proof areas of ships. However, deep well pumps need to be regularly inspected and repaired, during which they must be lifted and moved to the designated area. Traditional lifting methods mostly use hand chain hoists as lifting tools. This method is not only inefficient and has a low safety factor, but also lacks transportation functions and cannot directly transport the lifted deep well pump to the maintenance site.

[0003] Chinese patent application CN116040470A discloses a device for overhauling a deep well pump, which includes: a frame, which includes a load-bearing beam, a seat and a fixing part, the seat is vertically installed at both ends of the load-bearing beam, and the fixing parts are distributed on the lower side of the load-bearing beam and inside the seat; a lifting component, which includes a lifting part and a limiting part, the lifting part is arranged on the load-bearing beam, and the limiting part is located between the two seats; a moving component, which is composed of a transmission part and a moving part, one end of the transmission part is connected to the lifting part, and the other end is connected to the moving part, the seat includes a column, a leg and a protrusion, the column is a hollow structure, one end is connected to the load-bearing beam, and the other end is connected to the leg, and the protrusion is arranged on the opposite surfaces of the columns on both sides.

[0004] The above scheme uses a motor to drive the deep well pump to lift the pump, but the entire lifting device takes up a large space, and its gantry structure limits flexibility, resulting in a large amount of available space on the ship being occupied. In contrast, many existing simple marine lifting devices have a small footprint and a circular working area. Compared with gantry lifting equipment, they are more compact and more suitable for use on ships. However, these simple lifting devices have the problem of long installation time, and the connection with the ship is relatively weak, which poses a risk of tipping over during lifting.

At the same time, a locking unit is provided to lock the first clamping block, which improves the installation efficiency of the lifting device and ensures the stability of the lifting device when in use.

[0006] In order to solve the problems of the prior art, the present invention provides an intelligent lifting device for deep well pump maintenance, comprising a mounting groove vertically opened on a ship board; the mounting groove is a cylindrical structure, and a first clamping groove is evenly opened on the side wall of the mounting groove around the axis of the mounting groove, and the first clamping groove is arranged along the radial direction of the mounting groove.

[0007] Preferably, a receiving plate is arranged in the installation groove for movement in the vertical direction, and the receiving plate and the installation groove can only slide and cooperate with each other in the vertical direction. There is a first gap between the receiving plate and the bottom of the installation groove, and a first spring is arranged in the first gap, whose two ends are respectively fixedly connected to the receiving plate and the bottom of the installation groove. A plug-in slot is opened on the upper part of the receiving plate, and the plug-in slot is a non-circular structure. A plug-in block is fixedly arranged at the bottom of the base, and the plug-in block is plug-fitted with the plug-in slot.

[0008] Preferably, the horizontal cross-section of the plug-in block and the horizontal cross-section of the plug-in slot are the same in shape and size, the plug-in block is a polygonal column structure, and the number of edges of the plug-in block is the same as the number of the first clamping slots.

[0010] Preferably, an extension rod is fixedly provided in the vertical direction on the upper part of the second clamping block, a sleeve is provided on the outer periphery of the extension rod, the extension rod and the sleeve are slidably matched, a second gap is provided between the bottom of the sleeve and the second clamping block, a second spring is provided in the second gap, and both ends of the second spring are fixedly connected to the second clamping block and the sleeve respectively.

[0011] Preferably, a bracket is fixedly provided on the upper part of the base, the sleeve passes through the bracket in the vertical direction and slides with the bracket, there is a third gap between the upper end of the sleeve and the upper end of the bracket, a third spring is arranged in the vertical direction in the third gap, and both ends of the third spring are fixedly connected to the upper ends of the bracket and the sleeve respectively.

[0012] Preferably, a first roller is rotatably arranged on the upper part of each sleeve, and a trigger block is correspondingly arranged above each first roller.

When the base is fully inserted into the mounting groove, the rotating disk on the upper part of the base is rotated, and the inclined groove arranged on the rotating disk rotates synchronously. The first clamping assembly moves toward the side wall of the mounting groove under the guidance of the inclined groove. Since the first clamping assembly and the first clamping groove correspond to each other, and the base cannot rotate around its own axis in the mounting groove, the first clamping assembly can slide smoothly into the first clamping groove. At the same time, the locking unit arranged above the base will lock the first clamping assembly to ensure that in the subsequent use process, the rotating disk will not rotate accidentally due to the external force in the lifting operation, thereby avoiding the phenomenon that the first clamping assembly slides out of the first clamping groove, and ensuring the stability of the base installation. Compared with the traditional lifting device installation method, the lifting device installation method in the present invention is not only faster, but also avoids the damage of the screws caused by uneven torque during the installation of the screws, and further ensures the stability during lifting.

[0018] 2.

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] Reference Figure 1 , Figure 2 , Fig. 9 and Fig.11 : An intelligent lifting device for deep well pump maintenance, comprising a mounting groove 21 vertically opened on a shipboard 2; the mounting groove 21 is a cylindrical structure, and a first clamping groove 211 is evenly opened on the side wall of the mounting groove 21 around the axis of the mounting groove 21, and the first clamping groove 211 is arranged along the radial direction of the mounting groove 21, and a base 1 plugged with the mounting groove 21 is arranged in the mounting groove 21, and the base 1 is a cylindrical shell structure, and a first clamping assembly 11 is arranged in the base 1 along the radial direction of the base 1, and a plurality of first clamping assemblies 11 are arranged, and the plurality of first clamping assemblies 11 are evenly arranged around the axis of the base 1 and connected one by one with the first clamping groove 211. Correspondingly, each first snap-fitting groove 211 can be snap-fitted with the corresponding first snap-fitting assembly 11. A rotating disk 12 is rotatably arranged on the upper part of the base 1. The rotating disk 12 rotates around its own axis, and the axis of the rotating disk 12 is colinear with the axis of the base 1. A plurality of inclined grooves 121 are evenly distributed around the axis of the rotating disk 12 on the rotating disk 12. The first snap-fitting assembly 11 extends into the inclined groove 121 and slidably cooperates with the inclined groove 121. A locking unit 13 is arranged on the moving path of the first snap-fitting assembly 11 for locking the first snap-fitting assembly 11 when it extends into the first snap-fitting groove 211. The locking unit 13 is arranged on the upper part of the base 1.

[0034] Most deep well pumps are cylindrical in structure. When hoisting the deep well pump, the hook 3 needs to be hung on one end of the deep well pump, and then the deep well pump can be lifted by the electric hoist 4. The lifting device of the deep well pump can be disassembled and removed after maintenance, thereby ensuring that the space on the shipboard 2 will not be blocked by the lifting device. The installation method of the existing detachable lifting device is relatively traditional, that is, when installing the lifting device, the staff needs to fix the bottom of the lifting device with the shipboard 2 by screws, and in order to ensure the stability of the connection, multiple screws need to be set between the lifting device and the shipboard 2 to complete the normal connection. The installation time is long, and during installation, it is necessary to ensure that the torque of each screw is the same, so as to ensure that the entire lifting device is in a vertical state. Otherwise, one side of the lifting device will be more worn and the other side will be less worn. In severe cases, the screws on the side with greater wear will be damaged and cannot be disassembled normally.

[0035] In order to avoid the above situation, the lifting device is redesigned, wherein the base 1 of the lifting device is designed with emphasis, so that the base 1 of the lifting device is more convenient to install and disassemble. The specific structure and installation method of the base 1 are as follows: A mounting groove 21 for mounting the base 1 is provided on the shipboard 2. When installing, the base 1 is inserted into the mounting groove 21 in the vertical direction. It is worth noting that the base 1 can slide and cooperate with the mounting groove 21 in the vertical direction, but the base 1 cannot rotate around its own axis in the mounting groove 21. After the base 1 is fully inserted into the mounting groove 21, the rotating disk 12 on the upper part of the base 1 is rotated, and the inclined groove 121 set on the rotating disk 12 rotates synchronously with the rotating disk 12. It is worth noting that there is an angle between the extension direction of the inclined groove 121 and the radial direction of the rotating disk 12. When the rotating disk 12 rotates, the inclined groove 121 drives the first clamping assembly 11 to move along the radial direction of the base 1. The first clamping assembly 11 moves toward the side wall of the mounting groove 21 under the guidance of the inclined groove 121. Since the first clamping assembly 11 and the first clamping groove 211 correspond to each other, and the base 1 cannot rotate around its own axis in the mounting groove 21, the first clamping assembly 11 can slide smoothly into the first clamping groove 211. When the first clamping assembly 11 completely slides into the first clamping groove 211, the first clamping assembly 11 is clamped with the first clamping groove 211, and the locking unit 13 arranged above the base 1 will also lock the first clamping assembly 11, ensuring that in the subsequent use, the rotating disk 12 will not rotate due to the rotation during the subsequent lifting operation, thereby avoiding the first clamping assembly 11 from slipping out of the first clamping groove 211, thereby ensuring the stability of the installation of the base 1. After the installation of the base 1 is completed, the support rods 14 are plugged in sequence and all of them are plugged into the upper part of the base 1, and an electric hoist 4 is arranged on the uppermost support rod 14, and a hook 3 is arranged below the electric hoist 4, so that the installation is completed.

[0036] When disassembling, the support rods 14 are removed in sequence, and then the rotating disk 12 is rotated in the opposite direction, the locking unit 13 unlocks the first clamping assembly 11, and the rotating disk 12 drives the first clamping assembly 11 to slide out of the first clamping groove 211 through the inclined groove 121, and then the base 1 is taken out from the installation groove 21. In this way, no screws are needed when installing the base 1 of the lifting device, which improves the installation efficiency, avoids the damage of the screws caused by uneven torque during the installation of the screws, and ensures the stability during lifting.

[0037] Reference Figure 4 , Figure 7 and Figure 9-11 : A receiving plate 22 is arranged in the installation groove 21 for movement along the vertical direction. The receiving plate 22 and the installation groove 21 can only slide and cooperate with each other along the vertical direction. There is a first gap between the receiving plate 22 and the bottom of the installation groove 21. A first spring 23 is arranged in the first gap, and its two ends are respectively fixedly connected to the receiving plate 22 and the bottom of the installation groove 21. A plug-in groove 221 is opened on the upper part of the receiving plate 22. The plug-in groove 221 is a non-circular structure. A plug-in block 222 is fixedly arranged at the bottom of the base 1, and the plug-in block 222 is plugged and cooperated with the plug-in groove 221.

[0038] By arranging a receiving plate 22 that can move in the vertical direction in the installation groove 21, it is ensured that when the lifting device is not used daily, the receiving plate 22 can rise under the action of the first spring 23 and cover the installation groove 21, which can prevent the staff from stepping on empty space when passing through the installation groove 21. At the same time, the receiving plate 22 can have a dust-proof function for the first clamping groove 211.

[0039] It is worth noting that when installing the base 1, it is necessary to set a minimum descending height for the descending receiving plate 22. In this way, a limit ring 24 is also provided in the installation groove 21. The limit ring 24 limits the descending receiving plate 22. When the receiving plate 22 descends to the position of the limit ring 24, it will no longer descend.

[0040] Reference Figure 1-Figure 11 : The horizontal cross-section of the plug-in block 222 is the same in shape and size as the horizontal cross-section of the plug-in slot 221 . The plug-in block 222 is a polygonal column structure, and the number of edges of the plug-in block 222 is the same as the number of the first clamping slot 211 .

[0041] The side lengths of each edge of the plug-in block 222 are equal, so that the number of edges of the plug-in block 222 is equal to the number of the first snap-in grooves 211, ensuring that as long as the plug-in block 222 at the bottom of the base 1 can be smoothly inserted into the plug-in groove 221 of the receiving plate 22, the end of the first snap-in component 11 located in the base 1 can face the first snap-in groove 211, and when the rotating disk 12 rotates, the first snap-in component 11 can be smoothly snapped into the first snap-in groove 211.

[0042] Reference Figure 5 and Fig.11 The first clamping assembly 11 includes a first clamping block 111 that moves along the radial direction of the base 1, and a second clamping groove 132 is vertically opened above each first clamping block 111. A second clamping block 131 corresponding to the second clamping groove 132 is vertically penetrated through the upper part of the base 1, and the second clamping block 131 is slidably matched with the upper part of the base 1 along the vertical direction, and the second clamping block 131 is clamped and matched with the second clamping groove 132.

[0043] Reference Figure 5 : An extension rod 134 is fixedly arranged in the vertical direction on the upper part of the second clamping block 131, and a sleeve 135 is sleeved on the outer periphery of the extension rod 134. The extension rod 134 and the sleeve 135 are slidably matched. There is a second gap between the bottom of the sleeve 135 and the second clamping block 131. A second spring 133 is arranged in the second gap, and the two ends of the second spring 133 are fixedly connected to the second clamping block 131 and the sleeve 135 respectively.

[0044] Reference Figure 5 and Figure 8 : A bracket 136 is fixedly arranged on the upper part of the base 1, and the sleeve 135 penetrates the bracket 136 in the vertical direction and slides with the bracket 136. There is a third gap between the upper end of the sleeve 135 and the upper end of the bracket 136. A third spring 137 is arranged in the vertical direction in the third gap, and the two ends of the third spring 137 are fixedly connected to the upper ends of the bracket 136 and the sleeve 135 respectively.

[0045] Reference Figure 5 and Figure 8 A first roller 1351 is rotatably arranged on the upper part of the sleeve 135, and a trigger block 138 is arranged above the first roller 1351. The number of the trigger blocks 138 corresponds to the number of the first rollers 1351. The trigger blocks 138 are evenly arranged around the axis of the base 1 and rotate synchronously with the rotating disk 12. When the trigger block 138 passes the first roller 1351, the sleeve 135 descends in the vertical direction.

[0046] Reference Figure 1 , Figure 5 and Fig.11 A pushing block 113 is arranged in the base 1 along the moving direction of the first clamping block 111, and the upper part of the pushing block 113 extends into the inclined groove 121 and slides with the inclined groove 121. There is a fourth gap between the pushing block 113 and the first clamping block 111, and a fourth spring 112 is arranged in the fourth gap along the moving direction of the pushing block 113, and the two ends of the fourth spring 112 are fixedly connected to the first clamping block 111 and the pushing block 113 respectively.

[0047] When in use, first insert the base 1 into the installation groove 21, and then rotate the rotating disk 12. At this time, the trigger block 138 rotates synchronously with the rotating disk 12. The rotating disk 12 pushes the pushing block 113 through the inclined groove 121. The pushing block 113 pushes the first clamping block 111 to move through the fourth spring 112. The first clamping block 111 moves toward the first clamping groove 211, and the second clamping groove 132 on the upper part of the first clamping block 111 gradually approaches the second clamping block 131. At this time, when the trigger block 138 that rotates synchronously with the rotating disk 12 moves to the top of the first roller 1351, the first roller 1351 presses the sleeve 135 downward, and the third spring 137 located between the sleeve 135 and the bracket 136 is squeezed. At the same time, the sleeve 135 also squeezes the second spring 133, and the elastic force of the second spring 133 acts on the second clamping block 131, so that the end of the second clamping block 131 abuts against the upper part of the first clamping block 111. When the first clamping block 111 moves along the radial direction of the base 1, the first clamping block 111 The first clamping block 111 is slidably matched with the end of the second clamping block 131. When the first clamping block 111 is completely inserted into the first clamping groove 211, the second clamping groove 132 at the upper end of the first clamping block 111 is just located below the second clamping block 131. The second clamping block 131 is inserted into the second clamping groove 132 under the elastic force of the second spring 133. In this way, the second clamping block 131 is clamped with the second clamping groove 132, thereby realizing self-locking and ensuring that the first clamping block 111 will not slide out of the first clamping groove 211 during the transportation of the deep well pump.

[0048] After use, when disassembling the lifting device, it is only necessary to rotate the rotating disk 12 in the opposite direction. At this time, the rotating disk 12 drives the pushing block 113 to reset through the inclined groove 121, and the pushing block 113 moves toward the center of the base 1 along the radial direction of the base 1, but at this time, the second clamping block 131 clamps the second clamping groove 132 on the first clamping block 111, and the second clamping block 131 cannot move synchronously with the pushing block 113, that is, at this time, the first clamping block 111 is still clamped in the first clamping groove 211, and as the pushing block 113 moves, the spring between the pushing block 113 and the first clamping block 111 gradually stretches. As the rotating disk 12 rotates in the opposite direction, the trigger block 138 also rotates out from above the first roller 1351 as the rotating disk 12 rotates, and the third spring 137 pushes the upper end of the sleeve 135 to rise, so that the squeezing force of the sleeve 135 on the second spring 133 is reduced, and the sleeve 135 drives the second clamping block 131 to rise through the second spring 133, so that the second clamping block 131 can slide out of the second clamping groove 132. Lubricating oil is coated in the second clamping groove 132, so that the friction force when the second clamping block 131 slides out of the second clamping groove 132 is reduced, ensuring that the second clamping block 131 can slide out of the second clamping groove 132 smoothly. After the second clamping block 131 slides out of the second clamping slot 132 , the first clamping block 111 is unlocked and retracts back into the base 1 under the pulling force of the fourth spring 112 , so that the base 1 can be smoothly removed from the installation slot 21 .

[0049] Therefore, the function of automatically locking or unlocking the first clamping block 111 is achieved by simply rotating the rotating disk 12, making the operation more convenient.

[0050] It is worth noting that the weight of the second clamping block 131 and the extension rod 134 is constant. When the sleeve 135 moves to the highest position, the second clamping block 131 will not directly contact the first clamping block 111. In this way, during the rising process of the sleeve 135, the second clamping block 131 clamped in the second clamping groove 132 will not move due to friction. Then the second spring 133 is gradually stretched during the rising process of the sleeve 135, and the second clamping block 131 is pulled out of the second clamping groove 132 by the elastic force of the second spring 133. In this way, it is ensured that the second clamping block 131 can be smoothly pulled out of the second clamping groove 132 when the sleeve 135 rises.

[0051] Reference Figure 3 and Fig.11 A rotating cylinder 15 is arranged above the rotating disk 12 . The rotating cylinder 15 and the rotating disk 12 are fixedly connected via a connecting column 151 . A rotating groove 16 is vertically opened on the upper part of the rotating cylinder 15 .

[0052] The trigger block 138 is fixedly disposed at the bottom of the rotating cylinder 15 .

[0053] Reference Figure 6 A plurality of second rollers 17 are evenly distributed around the axis of the rotating groove 16 at the bottom of the rotating groove 16. The second rollers 17 are arranged along the radial direction of the rotating groove 16 and can rotate around their own axes.

[0054] A plurality of support rods 14 are sequentially plugged in the vertical direction to form a support assembly of the lifting device, and the support assembly is plugged into the rotating groove 16. Since a second roller 17 is provided in the rotating groove 16, when the end of the support rod 14 is inserted into the rotating groove 16, the second roller 17 rolls with the end of the support rod 14, ensuring that the hook 3 can rotate smoothly after lifting the deep well pump, and the rotation of the support rod 14 will not drive the rotating disk 12 to rotate, thereby avoiding the locking unit 13 from being unlocked due to the accidental rotation of the rotating disk 12.

[0055] Working principle: A mounting groove 21 for mounting the base 1 is provided on the shipboard 2. When installing, the base 1 is inserted into the mounting groove 21 in the vertical direction. It is worth noting that the base 1 can slide and cooperate with the mounting groove 21 in the vertical direction, but the base 1 cannot rotate around its own axis in the mounting groove 21. After the base 1 is fully inserted into the mounting groove 21, the rotating disk 12 on the upper part of the base 1 is rotated, and the inclined groove 121 set on the rotating disk 12 rotates synchronously with the rotating disk 12. It is worth noting that there is an angle between the extension direction of the inclined groove 121 and the radial direction of the rotating disk 12. When the rotating disk 12 rotates, the inclined groove 121 drives the first clamping assembly 11 to move along the radial direction of the base 1. The first clamping assembly 11 moves toward the side wall of the mounting groove 21 under the guidance of the inclined groove 121. Since the first clamping assembly 11 and the first clamping groove 211 correspond to each other, and the base 1 cannot rotate around its own axis in the mounting groove 21, the first clamping assembly 11 can slide smoothly into the first clamping groove 211. When the first clamping assembly 11 completely slides into the first clamping groove 211, the first clamping assembly 11 is clamped with the first clamping groove 211, and the locking unit 13 arranged above the base 1 will also lock the first clamping assembly 11, ensuring that in the subsequent use process, the rotating disk 12 will not rotate due to the rotation during the subsequent lifting operation, avoiding the phenomenon that the first clamping assembly 11 slides out of the first clamping groove 211, ensuring the stability of the installation of the base 1. After the installation of the base 1 is completed, the support rods 14 are inserted in sequence and all inserted into the upper part of the base 1. The electric hoist 4 is arranged on the uppermost support rod 14, and the hook 3 is arranged below the electric hoist 4, so that the installation is completed. When in use, only the support rod 14 needs to be rotated, so that the hook 3 can drive the deep well pump to rotate, and the base 1 itself does not rotate.
