Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a convenient tooling kit for hoisting water pipes. Background Technology

[0002] Deep well pumps, as key equipment for extracting deep underground water, typically require dozens of sections of riser pipes extending hundreds of meters underground. During maintenance, these riser pipes must be brought to the surface section by section. Therefore, the safety and convenience of the hoisting tools directly affect maintenance efficiency and operational safety. Currently, hoisting tools for deep well pump riser pipes are mainly divided into two categories: traditional clamping fixtures and enclosed hoisting devices. With traditional clamping fixtures, the clamps need to be frequently disassembled and replaced after every 4-5 sections of riser pipe are hoisted. Furthermore, after removal, the clamps must be manually transported to the well for reinstallation, increasing the workload of maintenance personnel and extending maintenance time. Moreover, when crustal movement causes well tilting or misalignment, the riser pipe is prone to jamming during hoisting, easily leading to clamp disengagement, pipe falls, and other safety accidents, posing serious safety hazards.

[0003] To address the aforementioned issues, Chinese Patent No. CN212769350U discloses a closed-type hoisting device for deep well submersible pumps, comprising a bracket assembly, a disc clamp, and a water delivery pipe. The bracket assembly includes a concave plate, a connecting plate, and a limiting plate. A connecting plate is fixed between the middle of the two side plates of the concave plate. A limiting plate is rotatably connected to the end of one side plate of the concave plate. The rectangular area formed by the limiting plate and the connecting plate provides a limiting and blocking fit against the circumferential side of the water delivery pipe. This device restricts the water delivery pipe through the rectangular area and supports the connecting flange of the water delivery pipe using a second support column. Then, the water delivery pipe is restricted within the support area by locking with an L-shaped locking plate on the limiting plate. Finally, the water delivery pipe is hoisted using a hoisting support plate.

[0004] Although the existing devices mentioned above have improved the safety and efficiency of lifting water pipes to some extent, they still have the following shortcomings in actual use: First, the support structure of the bracket assembly needs to be deliberately avoided from the inner edge of the disc clamp, otherwise it will be difficult to disassemble the disc clamp; second, the support components of the bracket may block the bolt holes of the water pipe flange, affecting the insertion of the flange connection bolts and increasing the complexity of operation; in addition, the fixing and disassembly process requires multiple operations of the locking plate, bolts and screws, which is cumbersome and still cannot meet the needs of efficient maintenance. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing hoisting devices, such as difficulty in disassembling disc clamps, complex operation, and low efficiency, and to provide a convenient tooling kit for hoisting water pipes.

[0006] This utility model is achieved through the following technical solution: a convenient tooling kit for hoisting a water delivery pipe, including a bracket and a flange clamp; one end of the bracket is provided with a U-shaped opening, the width B of which is greater than the diameter of the water delivery pipe and smaller than the diameter of the flange at the end of the water delivery pipe; the bracket spans across the wellhead and is inserted into the outside of the water delivery pipe through the U-shaped opening, thereby forming a structure capable of supporting the water delivery pipe; a supporting column is provided on the top side of the bracket, the supporting column is located near the closed end of the U-shaped opening, and the top side of the supporting column can abut against the flange. The bottom side; the top side of the bracket is provided with a closing pin for closing the U-shaped opening. The closing pin is located away from the closed end of the U-shaped opening, and the closing pin cooperates with the U-shaped opening to form a closed opening. The water supply pipe is located inside the closed opening. The top of the flange clamp is provided with a lifting hole, and the bottom of the flange clamp is provided with a T-shaped latch that cooperates with the flange. The flange clamp is locked to the outside of the flange through the T-shaped latch. The flange clamp is provided with a positioning pin corresponding to the flange hole. The positioning pin can be inserted into the flange hole.

[0007] This invention eliminates the need to deliberately avoid the inner hole of the clamp or obstruct the flange bolt holes, thus solving the structural interference problem between the bracket and the clamp in the prior art. The cooperation between the U-shaped opening and the closing pin enables quick assembly and disassembly, avoiding the cumbersome operation of the L-shaped locking plate and limit bolts in the prior art, and significantly improving the efficiency of assembly and disassembly. The overall structure of this invention eliminates the risk of disengagement through multiple limiting mechanisms, namely, the cooperation of support, closure, and pin positioning, resulting in higher safety.

[0008] A further improvement of this utility model is that the closing pin includes a pin rod A and two horizontal bushings. The two horizontal bushings are symmetrically fixed on the brackets on both sides of the U-shaped opening. The pin rod A spans across the U-shaped opening, and the two ends of the pin rod A are respectively inserted into the two horizontal bushings.

[0009] Compared with the prior art, which requires rotating the limiting plate, adjusting the L-shaped locking plate, and tightening the limiting bolts, the above-mentioned design of this utility model enables the pin rod A to be inserted and closed immediately, and pulled out immediately, which greatly shortens the assembly and disassembly time and reduces labor intensity.

[0010] A further improvement of this utility model is that the supporting column can be located at a position between two adjacent flange holes on the flange.

[0011] Through the specific design of the above-mentioned support column, this utility model can avoid interference problems when workers disassemble flange bolts, thereby improving work efficiency.

[0012] A further improvement of this utility model is that the positioning pin includes a pin rod B and a vertical bushing, the vertical bushing is fixed to the side of the flange clamp, and the pin rod B is inserted into the vertical bushing.

[0013] The vertical bushing of this invention guides the pin B, ensuring that the pin is accurately inserted into the flange hole. This solves the positioning problem in the prior art where the screw needs to be repeatedly adjusted to match the semi-straight slot, making assembly and disassembly more convenient.

[0014] A further improvement of this utility model is that the pin B has an L-shaped structure, and the side of the flange clamp is provided with a fixing plate located above the vertical bushing. The horizontal part of the pin B can be placed on the fixing plate to fix the position of the pin B.

[0015] Compared to the existing technology that requires tightening the limiting bolts to prevent the locking plate from falling off, this design of the present invention can achieve the anti-detachment effect simply by inserting and overlapping, reducing the number of operation steps; and the L-shaped structure makes it easy to hold and insert / remove, further improving the operation efficiency.

[0016] A further improvement of this utility model is that two positioning pins are provided, which are arranged on both sides of the flange clamp and located at both ends of the T-shaped bayonet.

[0017] The specific design of this positioning pin ensures balanced force on the flange, avoiding flange misalignment issues that may occur with single-screw positioning in existing technologies; at the same time, the double-sided pins enhance the connection strength between the clamp and the flange.

[0018] A further improvement of this utility model is that the top of the flange clamp has a triangular structure.

[0019] This triangular structure, while ensuring load-bearing strength, is lighter and reduces material consumption compared to existing disc clamps; it is also simple in structure, easy to carry and install, and suitable for narrow wellhead spaces.

[0020] A further improvement of this utility model is that the bracket has a rectangular structure.

[0021] The rectangular structure has a simple manufacturing process, which significantly reduces processing costs compared to the existing concave plate + connecting plate combination structure; moreover, the flat long side makes it easy to place stably at the wellhead, and it has greater versatility to adapt to wellheads of different specifications.

[0022] A further improvement of this utility model is that a mouth-shaped handle is provided at the other end of the bracket.

[0023] This design solves the problem of inconvenient handling caused by the lack of a grip structure in existing technologies, reduces the burden of manual handling, and is especially suitable for scenarios where the bracket is moved frequently, thereby improving work efficiency.

[0024] A further improvement of this utility model is that guide arc surfaces are respectively provided on both sides of the open end of the U-shaped opening.

[0025] Compared to the existing technology where the open semi-straight slot requires precise alignment with the water pipe before it can be fitted, the guide arc surface design reduces the difficulty of installation and alignment, allowing the bracket to be quickly fitted with the water pipe and shortening the preparation time.

[0026] As can be seen from the above technical solutions, the beneficial effects of this utility model are: 1. This utility model, through optimized structural design, completely solves the structural interference problem existing in enclosed hoisting devices. Existing bracket supports require deliberate avoidance of the inner edge of the disc clamp's hole and easily obstruct the bolt holes of the water pipe flange, leading to difficulties in clamp disassembly or bolt insertion. In contrast, the bracket in this solution uses a U-shaped opening with a closed pin structure, and the flange clamp is fixed to the positioning pin via a T-shaped latch. The two intersect without interference, eliminating the need to consider avoidance issues and fundamentally eliminating operational obstacles caused by structural conflicts.

[0027] 2. In terms of ease of operation, this utility model represents a significant improvement over existing technologies. Existing technologies require multiple steps to achieve fixation, including rotating the limiting plate, adjusting the L-shaped locking plate, tightening the limiting bolts, and coordinating the screw and positioning sleeve, making assembly and disassembly cumbersome. In contrast, the bracket of this utility model can achieve water pipe positioning simply by inserting and removing the sealing pin. The flange clamp only needs to be inserted into the positioning pin and rotated 90° to prevent detachment. No tools are required during assembly and disassembly, greatly shortening the operation time, reducing the labor intensity of maintenance personnel, and improving the hoisting efficiency of each section of water pipe.

[0028] 3. This utility model offers superior safety and practicality. Existing support structures rely on two-point support and bolt locking, posing a risk of disengagement when the water pipe becomes stuck. This utility model, however, utilizes three-point support of the bracket, radial limiting of the sealing pin, and circumferential fixing of the positioning pin to create multiple layers of protection, completely eliminating the hazards of wire rope disengagement and water pipe falling. Furthermore, the bracket's open handle, the U-shaped guide arc surface, and the lightweight triangular design of the flange clamp further enhance the tooling's portability and adaptability to various scenarios, making it more suitable for the complex working conditions of deep well pump maintenance.

[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0036] Now refer to Figures 1-4The following is a description of a specific embodiment: The present invention provides a convenient tooling kit for hoisting a water delivery pipe, comprising a bracket 1 and a flange clamp 4. One end of the bracket 1 is provided with a U-shaped opening 101, the width B of which is greater than the diameter of the water delivery pipe 7 and smaller than the diameter of the flange 701 at the end of the water delivery pipe 7. The bracket 1 spans across the wellhead 8 and is inserted into the outside of the water delivery pipe 7 through the U-shaped opening 101, thereby forming a structure capable of supporting the water delivery pipe 7. A supporting column 3 is provided on the top side of the bracket 1, the supporting column 3 being located near the closed end of the U-shaped opening 101, and the top side of the supporting column 3 abutting against the bottom side of the flange 701. The top side of the bracket 1 is provided with a closing pin 2 for closing the U-shaped opening 101. The closing pin 2 is located away from the closed end of the U-shaped opening 101, and the closing pin 2 cooperates with the U-shaped opening 101 to form a closed opening 5. The water supply pipe 7 is located inside the closed opening 5. The top of the flange clamp 4 is provided with a lifting hole 401, and the bottom of the flange clamp 4 is provided with a T-shaped bayonet 402 that cooperates with the flange 701. The flange clamp 4 is locked to the outside of the flange 701 through the T-shaped bayonet 402. The upper part of the flange clamp 4 is provided with a positioning pin 6 corresponding to the flange hole 702. The positioning pin 6 can be inserted into the flange hole 702.

[0037] The bracket 1 is fitted onto the outside of the water delivery pipe 7 through the U-shaped opening 101. Because the width B of the U-shaped opening 101 is greater than the diameter of the water delivery pipe 7 and less than the diameter of the flange 701, the bracket 1 can directly support the flange 701 of the water delivery pipe 7 when it spans the wellhead 8, preventing the water delivery pipe 7 from falling. The support column 3 abuts against the bottom side of the flange 701, further enhancing the support stability of the flange 701 and forming an interval space that is convenient for workers to operate. The sealing pin 2 closes the U-shaped opening 101 to form a closed opening 5, restricting the radial sway of the water delivery pipe 7. The flange clamp 4 clamps the flange 701 through the T-shaped clamp 402, and the positioning pin 6 is inserted into the flange hole 702 to achieve circumferential fixation. The lifting hole 401 connects to the lifting equipment to complete the segmented lifting.

[0038] This invention eliminates the need to deliberately avoid the inner hole of the clamp or obstruct the flange bolt holes, thus solving the structural interference problem between the bracket and the clamp in the prior art. The cooperation between the U-shaped opening 101 and the closing pin 2 enables quick assembly and disassembly, avoiding the cumbersome operation of the L-shaped locking plate and limit bolts in the prior art, and significantly improving the efficiency of assembly and disassembly. The overall structure of this invention eliminates the risk of disengagement through multiple limiting mechanisms, namely, the cooperation of support, closure, and pin positioning, resulting in higher safety.

[0039] Specifically, refer to Figure 3The closing pin 2 includes a pin rod A201 and two horizontal bushings 202. The two horizontal bushings 202 are symmetrically fixed on the brackets 1 on both sides of the U-shaped opening 101. The pin rod A201 spans across the U-shaped opening 101, and the two ends of the pin rod A201 are respectively inserted into the two horizontal bushings 202.

[0040] The two horizontal bushings 202 of the closing pin 2 are fixed on both sides of the U-shaped opening 101. The pin rod A201 spans the U-shaped opening 101 and is inserted into the bushing. The U-shaped opening 101 can be quickly closed and opened by inserting and pulling the pin rod A201.

[0041] Compared with the prior art, which requires rotating the limiting plate, adjusting the L-shaped locking plate, and tightening the limiting bolts, the above-mentioned design of this utility model enables the pin rod A201 to close with one insertion and open with one pull, which greatly shortens the assembly and disassembly time and reduces labor intensity.

[0042] Specifically, refer to Figure 3 The supporting column 3 can be located at a position between two adjacent flange holes 702 on the flange 701.

[0043] Through the specific design of the above-mentioned support column 3, this utility model can avoid the problem of interference when workers disassemble flange bolts, thereby improving work efficiency.

[0044] Specifically, refer to Figure 4 The positioning pin 6 includes a pin rod B601 and a vertical bushing 602. The vertical bushing 602 is fixed to the side of the flange clamp 4, and the pin rod B601 is inserted into the vertical bushing 602.

[0045] The vertical bushing 602 of the positioning pin 6 is fixed to the side of the flange clamp 4. The pin rod B601 is inserted along the axial direction of the bushing, precisely aligned and passed through the flange hole 702, so as to achieve circumferential fixation between the flange clamp 4 and the flange 701.

[0046] The vertical bushing 602 of this utility model guides the pin B601, ensuring that the pin is accurately inserted into the flange hole 702. This solves the positioning problem in the prior art where the screw needs to be repeatedly adjusted to match the semi-straight slot, making assembly and disassembly more convenient.

[0047] Specifically, refer to Figure 4 The pin B601 has an L-shaped structure. The flange clamp 4 has a fixing plate 603 located above the vertical bushing 602 on its side. The horizontal part of the pin B601 can be placed on the fixing plate 603 to fix the position of the pin B601.

[0048] After the L-shaped pin B601 is inserted into the flange hole, its horizontal part rests on the fixing plate 603. The pin B601 is prevented from falling off axially by gravity and the limiting effect of the fixing plate 603.

[0049] Compared to the existing technology that requires tightening the limiting bolts to prevent the locking plate from falling off, this design of the present invention can achieve the anti-detachment effect simply by inserting and overlapping, reducing the number of operation steps; and the L-shaped structure makes it easy to hold and insert / remove, further improving the operation efficiency.

[0050] In one embodiment, reference Figure 4 There are two positioning pins 6, which are arranged on both sides of the flange clamp 4 and located at both ends of the T-shaped bayonet 402.

[0051] The specific design of this positioning pin 6 enables the flange to be subjected to balanced force, avoiding the flange displacement problem that may be caused by a single screw positioning in the prior art; at the same time, the double-sided pins enhance the connection strength between the clamp and the flange.

[0052] In one embodiment, reference Figure 4 The top of the flange clamp 4 has a triangular structure.

[0053] The top of the flange clamp 4 adopts a triangular structure, and the lifting hole 401 is set at the top of the triangle to distribute the tensile force during lifting by utilizing the mechanical stability of the triangle.

[0054] This triangular structure, while ensuring load-bearing strength, is lighter and reduces material consumption compared to existing disc clamps; it is also simple in structure, easy to carry and install, and suitable for narrow wellhead spaces.

[0055] In one embodiment, reference Figure 3 The bracket 1 has a rectangular structure.

[0056] The long side of the rectangular bracket 1 spans across the well opening 8, and the width of the short side is adapted to the size of the well opening 8. When placed, it fits against the edge of the well opening 8 to form a stable supporting base.

[0057] The rectangular structure has a simple manufacturing process, which significantly reduces processing costs compared to the existing concave plate + connecting plate combination structure; and the flat long side makes it easy to place stably on the wellhead 8, making it more versatile and adaptable to different specifications of wellhead 8.

[0058] In one embodiment, reference Figure 3 The other end of the bracket 1 is provided with a mouth-shaped handle 102.

[0059] The mouth-shaped handle 102 at the other end of the bracket 1 is for the operator to hold, making it easy to move the bracket 1 to or from the wellhead 8.

[0060] This design solves the problem of inconvenient handling caused by the lack of a grip structure in existing technologies, reduces the burden of manual handling, and is especially suitable for scenarios where the bracket is moved frequently, thereby improving work efficiency.

[0061] In one embodiment, reference Figure 3 The U-shaped opening 101 has guide arc surfaces 103 on both sides of its open end.

[0062] The guide arc surface 103 at the open end of the U-shaped opening 101 provides an inclined guide for the water delivery pipe 7 to enter the U-shaped opening 101. The water delivery pipe can slide into the U-shaped opening 101 along the arc surface without the need for precise alignment.

[0063] Compared to the existing technology where the open semi-straight slot requires precise alignment with the water pipe 7 before it can be inserted, the design of the guide arc surface 103 reduces the difficulty of installation alignment, enabling the bracket 1 to quickly insert the water pipe 7 and shorten the preparation time.

[0064] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
