Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and specifically to an intelligent lifting device for deep well pump maintenance. Background Art

[0002] As a water pumping device, deep well pumps are widely used in various fields, including the explosion-proof areas of ships. However, deep well pumps need to be regularly maintained, and during this process, they must be lifted and moved to a designated area. Traditional lifting methods mostly use chain hoists as lifting tools. This method not only has low efficiency and a low safety factor, but also lacks a transportation function and cannot directly transport the lifted deep well pump to the maintenance location.

[0003] Chinese Patent Application CN116040470A discloses a device for deep well pump maintenance. The device includes: a frame, which includes a load-bearing beam, vertical seats, and fixing members. The vertical seats are vertically installed at both ends of the load-bearing beam, and the fixing members are distributed on the lower side of the load-bearing beam and inside the vertical seats; a lifting assembly, which includes a lifting member and a limiting member. The lifting member is arranged on the load-bearing beam, and the limiting member is located between the two vertical seats; a moving assembly, which is composed of a transmission member and a moving member. One end of the transmission member is connected to the lifting member, and the other end is connected to the moving member. The vertical seat includes a column, a leg, and a convex block. The column is a hollow structure, one end is connected to the load-bearing beam, the other end is connected to the leg, and the convex block is arranged on the opposite surfaces of the two columns.

[0004] The above solution realizes the lifting of the deep well pump through motor drive, but the entire lifting device occupies 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 smaller floor area, and the working area is circular, which is more compact than gantry lifting equipment and is more suitable for use on ships. However, these simple lifting devices have the problem of a long installation time, and the connection with the ship is relatively weak, posing a risk of tipping during lifting. Summary of the Invention

By setting a rotating disk, the first clamping block arranged in the base extends out after the base is inserted into the installation groove, and the extended first clamping block can be clamped and matched with the first clamping groove on the side wall of the installation groove. At the same time, there is a locking unit to lock the first clamping block, which improves the installation efficiency of the lifting device and also ensures the stability of the lifting device during use.

[0011] Preferably, a bracket is fixedly arranged on the upper part of the base. The sleeve penetrates through the bracket in the vertical direction and is slidably matched with the bracket. There is a third gap between the upper end of the sleeve and the upper end of the bracket.

[0032] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0033] Referring to Figure 1 、 Figure 2 、 Figure 9 and Figure 11 : An intelligent lifting device for deep well pump maintenance, including an installation groove 21 vertically opened on a boat plate 2; the installation groove 21 is a cylindrical structure, and on the side wall of the installation groove 21, first clamping grooves 211 are evenly opened around the axis of the installation groove 21, the first clamping grooves 211 are arranged along the radial direction of the installation groove 21, a base 1 that is in plug-in fit with the installation groove 21 is arranged in the installation groove 21, the base 1 is a cylindrical shell structure, a first clamping assembly 11 is arranged in the base 1 along the radial direction of the base 1, there are multiple first clamping assemblies 11, the multiple first clamping assemblies 11 are evenly arranged around the axis of the base 1 and correspond to the first clamping grooves 211 one by one, each first clamping groove 211 can be in clamping fit with the corresponding first clamping 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 collinear with the axis of the base 1, multiple tilted grooves 121 are evenly distributed around the axis of the rotating disk 12 on the rotating disk 12, the first clamping assembly 11 extends into the tilted grooves 121 and is in sliding fit with the tilted grooves 121, and a locking unit 13 for locking the first clamping assembly 11 when it extends into the first clamping groove 211 is arranged on the moving path of the first clamping assembly 11, and the locking unit 13 is arranged on the upper part of the base 1.

[0034] Deep well pumps are mostly cylindrical in structure. When hoisting a deep well pump, the hook 3 needs to be hung at one end of the deep well pump, and then the deep well pump can be lifted by an electric hoist 4. After the deep well pump is repaired, the lifting device can be disassembled and removed, thus ensuring that the space on the ship's plate 2 will not be blocked by the lifting device all the time. However, the installation method of the existing detachable lifting device is relatively traditional. That is, when installing the lifting device, the staff needs to fixedly connect the bottom of the lifting device to the ship's plate 2 with screws. And to ensure the stability of the connection, multiple screws need to be set between the lifting device and the ship's plate 2 to complete the normal connection. The installation time is relatively long, and when installing, it is necessary to ensure that the torque of each screw is the same, so as to ensure that the whole lifting device is in a vertical state. Otherwise, the situation of larger wear on one side and smaller wear on the other side of the lifting device will occur. Seriously, the screws on the side with larger wear may be damaged and cannot be disassembled normally.

[0035] In order to avoid the above situation, the lifting device is redesigned. Among them, the base 1 of the lifting device is redesigned with emphasis to make the installation and disassembly of the base 1 of the lifting device more convenient. The specific structure and installation method of the base 1 are as follows:

[0036] An installation groove 21 for installing the base 1 is provided on the ship plate 2. During installation, the base 1 is inserted vertically into the installation groove 21. It should be noted that the base 1 can slide vertically with the installation groove 21, but the base 1 cannot rotate around its own axis in the installation groove 21. After the base 1 is completely inserted into the installation groove 21, the rotating disc 12 on the upper part of the base 1 is rotated. The inclined groove 121 provided on the rotating disc 12 rotates synchronously with the rotating disc 12. It should be noted that there is an included angle between the extending direction of the inclined groove 121 and the radial direction of the rotating disc 12. When the rotating disc 12 rotates, the inclined groove 121 drives the first clamping component 11 to move in the radial direction of the base 1. The first clamping component 11 moves towards the side wall of the installation groove 21 under the guidance of the inclined groove 121. Since the first clamping component 11 and the first clamping groove 211 correspond to each other, and at the same time the base 1 cannot rotate around its own axis in the installation groove 21, in this way, the first clamping component 11 can smoothly slide into the first clamping groove 211. When the first clamping component 11 completely slides into the first clamping groove 211, the first clamping component 11 completes the clamping with the first clamping groove 211. At the same time, the locking unit 13 provided above the base 1 will also lock the first clamping component 11, ensuring that during subsequent use, the rotating disc 12 will not rotate due to the rotation during subsequent hoisting operations, avoiding the phenomenon that the first clamping component 11 slides out of the first clamping groove 211, and ensuring the stability of the installation of the base 1. After the installation of the base 1 is completed, the support rods 14 are sequentially inserted and all inserted on the upper part of the base 1. An electric hoist 4 is provided on the uppermost support rod 14, and a hook 3 is provided below the electric hoist 4. In this way, the installation is completed.

[0037] During disassembly, the support rods 14 are sequentially removed, and then the rotating disc 12 is rotated in the reverse direction. The locking unit 13 unlocks the first clamping component 11. The rotating disc 12 drives the first clamping component 11 to slide out of the first clamping groove 211 through the inclined groove 121, and then the base 1 can be taken out of the installation groove 21. In this way, screws are not needed when installing the base 1 of the hoisting device, improving the installation efficiency and avoiding the situation of screw damage caused by uneven torque during screw installation, ensuring the stability during hoisting.

[0038] Refer to Figure 4 、 Figure 7 and Figures 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.

[0039] 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.

[0040] 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.

[0041] Reference Figures 1 - 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 .

[0042] 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.

[0043] Reference Figure 5 and Figure 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.

[0044] Reference Figure 5: An extension rod 134 is fixedly arranged vertically on the upper part of the second clamping block 131. A sleeve 135 is sleeved outside the extension rod 134. The extension rod 134 is in sliding fit with the sleeve 135. 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. The two ends of the second spring 133 are respectively fixedly connected to the second clamping block 131 and the sleeve 135.

[0045] Refer to Figure 5 and Figure 8 : A bracket 136 is fixedly arranged on the upper part of the base 1. The sleeve 135 penetrates through the bracket 136 vertically and is in sliding fit 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 vertically in the third gap. The two ends of the third spring 137 are respectively fixedly connected to the bracket 136 and the upper end of the sleeve 135.

[0046] Refer to Figure 5 and Figure 8 : A first roller 1351 is rotatably arranged on the upper part of the sleeve 135. A trigger block 138 is arranged above the first roller 1351. The number of trigger blocks 138 corresponds one-to-one to the number of first rollers 1351. The trigger blocks 138 are arranged evenly around the axis of the base 1 and rotate synchronously with the rotating disc 12. When the trigger block 138 passes by the first roller 1351, the sleeve 135 descends vertically.

[0047] Refer to Figure 1 、 Figure 5 and Figure 11 : A pushing block 113 is movably arranged in the base 1 along the moving direction of the first clamping block 111. The upper part of the pushing block 113 extends into the inclined groove 121 and is in sliding fit with the inclined groove 121. There is a fourth gap between the pushing block 113 and the first clamping block 111. A fourth spring 112 is arranged along the moving direction of the pushing block 113 in the fourth gap. The two ends of the fourth spring 112 are respectively fixedly connected to the first clamping block 111 and the pushing block 113.

[0048] During 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 through the fourth spring 112. The first clamping block 111 moves towards the first clamping groove 211, and the second clamping groove 132 on the upper part of the first clamping block 111 also gradually approaches the second clamping block 131. When the trigger block 138 that rotates synchronously with the rotating disk 12 moves above the first roller 1351, the first roller 1351 presses down the sleeve 135. The third spring 137 located between the sleeve 135 and the bracket 136 is compressed. At the same time, the sleeve 135 also compresses the second spring 133. 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 in the radial direction of the base 1, the first clamping block 111 and the end of the second clamping block 131 are in sliding fit. 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 exactly 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 engaged with the second clamping groove 132, thus realizing self-locking and ensuring that the first clamping block 111 will not slip out of the first clamping groove 211 during the transportation of the deep well pump.

[0049] After use, when disassembling the lifting device, just rotate the rotating disk 12 in the reverse direction. At this time, the rotating disk 12 drives the pushing block 113 to perform a reset operation through the inclined groove 121. The pushing block 113 moves towards the center of the base 1 along the radial direction of the base 1. However, 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. As the pushing block 113 moves, the spring between the pushing block 113 and the first clamping block 111 is gradually stretched. And the trigger block 138 also rotates in the reverse direction with the rotating disk 12. The trigger block 138 rotates out from above the first roller 1351 as the rotating disk 12 rotates. The third spring 137 pushes the upper end of the sleeve 135 to rise. In this way, the extrusion force of the sleeve 135 on the second spring 133 is reduced. The sleeve 135 drives the second clamping block 131 to rise through the second spring 133. In this way, the second clamping block 131 can slide out of the second clamping groove 132. Lubricating oil is coated in the second clamping groove 132. In this way, the friction when the second clamping block 131 slides out of the second clamping groove 132 is reduced, ensuring that the second clamping block 131 can smoothly slide out of the second clamping groove 132. After the second clamping block 131 slides out of the second clamping groove 132, the first clamping block 111 is unlocked. The first clamping block 111 retracts into the base 1 under the pulling force of the fourth spring 112. In this way, the base 1 can be smoothly taken out from the installation groove 21.

[0050] Thus, the function of automatically locking or unlocking the first clamping block 111 can be achieved only by rotating the rotating disk 12, making the operation more convenient.

[0051] It should be noted that the weights of the second clamping block 131 and the extension rod 134 are constant. When the sleeve 135 moves up to the highest position, the second clamping block 131 will not directly contact the first clamping block 111. Thus, during the rising process of the sleeve 135, the second clamping block 131 clamped in the second clamping groove 132 does not move due to friction first. Then, the second spring 133 is gradually stretched during the rising process of the sleeve 135. The elastic force of the second spring 133 pulls out the second clamping block 131 from the second clamping groove 132. In this way, it is ensured that when the sleeve 135 rises, the second clamping block 131 can smoothly be pulled out from the second clamping groove 132.

[0052] Refer to Figure 3 and Figure 11 : A rotating cylinder 15 is arranged above the rotating disk 12. The rotating cylinder 15 and the rotating disk 12 are fixedly connected through a connecting column 151. A rotating groove 16 is vertically opened in the upper part of the rotating cylinder 15.

[0053] The trigger block 138 is fixedly arranged at the bottom of the rotating cylinder 15.

[0054] Refer to Figure 6 : At the bottom of the rotating groove 16, a plurality of second rollers 17 evenly distributed around the axis of the rotating groove 16 are provided. The second rollers 17 are arranged along the radial direction of the rotating groove 16 and can rotate around their own axes.

[0055] A plurality of support rods 14 are sequentially inserted vertically to form a support assembly of the lifting device, and the support assembly is inserted into the rotating groove 16. Since the second rollers 17 are provided in the rotating groove 16, when the end of the support rod 14 is inserted into the rotating groove 16, the second rollers 17 will rollingly cooperate with the end of the support rod 14, ensuring that the hook 3 can rotate smoothly after lifting the deep well pump, and the support rod 14 will not drive the rotating disk 12 to rotate when rotating, avoiding the unlocking of the locking unit 13 due to the accidental rotation of the rotating disk 12.

[0056] Working principle: An installation groove 21 for installing the base 1 is provided on the ship plate 2. During installation, the base 1 is inserted vertically into the installation groove 21. It should be noted that the base 1 can slide vertically with the installation groove 21, but the base 1 cannot rotate around its own axis in the installation groove 21. After the base 1 is completely inserted into the installation groove 21, the rotating disk 12 on the upper part of the base 1 is rotated, and the inclined groove 121 provided on the rotating disk 12 rotates synchronously with the rotating disk 12. It should be noted that the extending direction of the inclined groove 121 has an included angle with the radial direction of the rotating disk 12. When the rotating disk 12 rotates, the inclined groove 121 drives the first clamping component 11 to move along the radial direction of the base 1. The first clamping component 11 moves towards the side wall of the installation groove 21 under the guidance of the inclined groove 121. Since the first clamping component 11 and the first clamping groove 211 correspond to each other, and at the same time the base 1 cannot rotate around its own axis in the installation groove 21, thus the first clamping component 11 can smoothly slide into the first clamping groove 211. When the first clamping component 11 completely slides into the first clamping groove 211, the first clamping component 11 completes the clamping with the first clamping groove 211, and at the same time the locking unit 13 provided above the base 1 will also lock the first clamping component 11, ensuring that during subsequent use, the rotating disk 12 will not rotate due to the rotation during subsequent hoisting operations, avoiding the phenomenon that the first clamping component 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 sequentially inserted and all inserted above the base 1. An electric hoist 4 is provided on the uppermost support rod 14, and a hook 3 is provided below the electric hoist 4, thus completing the installation. During use, only by rotating the support rod 14 can the hook 3 drive the deep well pump to rotate, while the base 1 itself does not rotate.
