Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and more specifically, to a device for clamping and fixing cables during the installation of large submersible pump equipment. Background Technology

[0002] During the installation of large submersible pump equipment, one end of the cable is connected to the motor in the submersible pump and then hoisted to the ground. During this process, the laying and fixing of the cable (especially large cross-section power cable and multi-core control cable) is a key technical step.

[0003] In existing technologies, commonly used cable fixing techniques mainly include: 1. Single-point suspension fixing: The cable is fixed to a single point on the bracket by cable clamps or cable ties, resulting in stress concentration at the fixing point; 2. Rigid cable tray support: Metal cable trays are used to support the weight of the cables, but the stress distribution in different sections cannot be dynamically adjusted; 3. Segmented binding and fixing: Although it can achieve multi-point fixing, there is a lack of mechanical linkage between the fixing points, and it is impossible to form a systematic load-bearing structure.

[0004] The cable fixing techniques described above typically focus on securing the cable in a specific location, but they fail to adequately consider the effective distribution of the cable's total weight. This is especially true for large-section or heavy-duty cables, and these fixing methods present the following problems during installation and long-term operation: 1. Traditional single-point fixing causes the cable's self-weight stress to concentrate at the fixing point. If effective support and fixing measures are lacking during installation, it is very easy to cause conductor deformation and insulation layer damage. 2. Under dynamic operating conditions (such as submersible pump vibration, thermal expansion and contraction), alternating stress is easily generated at fixed points, which accelerates cable fatigue fracture; 3. The existing fixing method cannot suppress the lateral swing of the cable during the hoisting and lowering of the cable and submersible pump, which leads to friction damage to the insulation layer; 4. In the on-site method, during the hoisting and lowering of cables and submersible pumps, construction personnel need to adjust heavy cables by hand, which poses a risk of falling from height; the laying of cables for high-power submersible pumps requires multiple people to work together, resulting in low installation efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device for clamping and fixing cables during the installation of large submersible pump equipment, which can effectively transfer and disperse the total weight of the cable and prevent the cable from being damaged by gravity and mechanical stress during installation and use; The solution adopted by this utility model to solve the technical problem is: A device for clamping and fixing cables during the installation of large submersible pump equipment includes multiple sets of clamping members for clamping cables and steel wire ropes connected to the clamping members; the multiple sets of clamping members are arranged along the axial direction of the steel wire ropes. The clamping component is provided with multiple sets of clamping cavities for clamping cables and wire ropes.

[0006] In some possible implementations, the clamping member includes an upper plate, a lower plate that cooperates with the upper plate to form a clamping cavity, and a connecting assembly for connecting the upper plate and the lower plate.

[0007] In some possible implementations, the cable includes cable one and cable two; the clamping cavity is in three sets, including clamping cavity one for clamping cable one, clamping cavity two for clamping cable two, and clamping cavity three for clamping wire rope.

[0008] In some possible implementations, the third clamping cavity is located between the first clamping cavity and the second clamping cavity.

[0009] In some possible implementations, buffer layers that fit against the cable are respectively provided in the clamping cavity one and clamping cavity two, and the buffer layers are fitted on the outside of the cable.

[0010] In some possible implementations, the buffer layer includes a polyurethane foam layer disposed on the inner side of clamping cavity one or clamping cavity two, a rubber layer disposed on the polyurethane foam layer, and a nylon fiber layer disposed on the side of the rubber layer away from the polyurethane foam layer.

[0011] In some possible implementations, the upper plate and the lower plate have the same structure, both being elongated plate-like structures, and multiple sets of clamping cavities are arranged along the length direction of the elongated plate-like structures.

[0012] In some possible implementations, the connecting components are in multiple sets, and a clamping cavity is provided between two sets of the connecting components.

[0013] In some possible implementations, the connecting assembly includes a bolt with one end passing through the lower plate and the upper plate in sequence, and a nut suitable for cooperating with the bolt.

[0014] In some possible implementations, the cross-section of the buffer layer is semi-circular, and the clamping cavity is provided with an arc surface that fits the outer side of the buffer layer or the wire rope.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses multiple sets of clamping components to further clamp the cable in segments. The multiple sets of clamping components are arranged along the length of the steel wire rope and connected to the steel wire rope. Through the synergistic effect of the steel wire rope and the clamping components, the weight of the cable is gradually distributed to the steel wire rope, avoiding excessive stress at a single point. The steel wire rope effectively transfers and disperses the total weight of the cable, preventing damage to the cable due to gravity and mechanical stress during installation and use. This invention, through its buffer layer, can effectively absorb vibration and impact loads, reduce the impact force on the cable during installation and use, effectively protect the cable, and improve its service life. This utility model effectively connects the clamping component and the wire rope by setting the connecting component, ensuring that the weight of the cable can be smoothly transferred to the wire rope. This utility model has a simple structure and is highly practical. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] The present invention will now be described in detail.

[0019] like Figures 1-2 As shown: A device for clamping and fixing cables during the installation of large submersible pump equipment includes multiple sets of clamping members for clamping cables and steel wire ropes 5 connected to the clamping members; the multiple sets of clamping members are arranged along the axial direction of the steel wire ropes 5. The clamping member is provided with multiple sets of clamping cavities for clamping cables and wire ropes 5.

[0020] Specifically, when lowering the cable and submersible pump vertically, one end of the cable is connected to the submersible pump, and one end of the wire rope 5 is connected to the submersible pump. Then, a set of clamps is installed to fix the cable and wire rope 5. Then, the submersible pump, wire rope 5, and cable are lowered by the hoisting device. After the submersible pump has descended a certain distance, another set of clamps is installed to fix the cable and wire rope 5. This operation is repeated until the submersible pump is lowered to the designated position. By setting up multiple sets of clamping components, the weight of the cable is transferred to the wire rope 5 in segments. When the cable is lowered with the submersible pump, the multiple sets of clamping components set along the length of the wire rope 5 are used to clamp and fix the cable. The wire rope 5 is taut and vertically set throughout the entire process of lowering the submersible pump, so that the lowered cable will not rub against the inner wall of the well or pipe. By setting up multiple sets of clamping components, the weight of the cable is gradually distributed and transferred to the wire rope 5, avoiding excessive stress at a single point and effectively transferring the weight load of the cable. At the same time, since the clamping components clamp and fix the cable in sections, the cable will no longer require a large number of construction workers to hold the cable, which greatly improves the installation efficiency.

[0021] In some possible implementations, the clamping member includes an upper plate 1, a lower plate 2 that cooperates with the upper plate 1 to form a clamping cavity, and a connecting assembly for connecting the upper plate 1 and the lower plate 2.

[0022] Specifically, both the upper plate 1 and the lower plate 2 are made of aerospace-grade high-strength alloy, which has both high rigidity and lightweight characteristics, making them suitable for heavy-duty cable fixing. The upper plate 1 and the lower plate 2 are connected by a connecting component, which can realize the opening and closing function, making it convenient for cable installation and removal.

[0023] In some possible implementations, the cable includes cable one 6 and cable two 7; the clamping cavity is three sets, including clamping cavity one for clamping cable one 6, clamping cavity two for clamping cable two 7, and clamping cavity three for clamping wire rope 5.

[0024] In some possible implementations, the third clamping cavity is located between the first clamping cavity and the second clamping cavity.

[0025] In some possible implementations, a buffer layer 3 that fits against the cable is provided in the clamping cavity one and the clamping cavity two respectively. The buffer layer 3 is fitted on the outside of the cable, and the buffer layer 3 effectively protects the cable at the clamping and fixing point.

[0026] In some possible implementations, the buffer layer 3 includes a polyurethane foam layer disposed on the inner side of the clamping cavity, a rubber layer disposed on the polyurethane foam layer, and a nylon fiber layer disposed on the side of the rubber layer away from the polyurethane foam layer. Specifically, the polyurethane foam layer is a polyurethane foam with high resilience, which has good cushioning properties and can absorb the impact force generated by the cable due to gravity and vibration. The rubber layer is made of insulating rubber, which can effectively provide electrical isolation and has a certain degree of sealing to prevent dust and moisture from entering the gap between the clamp and the cable; The nylon fiber layer is aramid fiber reinforced nylon, which can effectively resist mechanical wear and ultraviolet aging, providing effective protection for the cable machinery.

[0027] In some possible implementations, the upper plate 1 and the lower plate 2 have the same structure, both being elongated plate-like structures, and multiple sets of clamping cavities are arranged along the length direction of the elongated plate-like structures; The upper plate 1 and the lower plate 2 are respectively provided with grooves on one side close to each other. The two sets of corresponding grooves cooperate to form a clamping cavity, thereby realizing the clamping and fixing of the cable and the wire rope 5. The cross-section of the groove is semi-circular.

[0028] In some possible implementations, there are multiple sets of connecting components, and a clamping cavity is provided between two sets of connecting components; Combination Figure 1 , Figure 2 As shown, there are four sets of connecting components and three sets of clamping cavities, thereby achieving effective fixation of the cables and wire ropes 5 clamped in the three sets of clamping cavities.

[0029] In some possible implementations, to facilitate the installation and removal of the cable, the connecting assembly 4 includes a bolt with one end passing through the lower plate 2 and the upper plate 1 in sequence, and a nut suitable for cooperating with the bolt.

[0030] In some possible implementations, the cross-section of the buffer layer 3 is semi-circular, and the two sets of buffer layers 3 in the same clamping cavity have the same structural dimensions and are fitted on the outside of the cable; the clamping cavity is provided with an arc surface that fits against the outside of the buffer layer 3 or the wire rope 5, the inner side of the buffer layer 3 fits against the outer side of the cable, and the outer side of the buffer layer 3 fits against the clamping cavity. Under the action of the connecting component, the cable can be effectively clamped and fixed.

[0031] It should be noted that: Before hoisting the submersible pump, one end of the steel wire rope 5 holding the clamping component is fixedly connected to the lifting ring of the submersible pump; one end of the cable is connected to the submersible pump. Then, a set of clamping components are installed; Specifically, the power cable (cable 6) and the control cable (cable 7) are installed on the lower plate 2, ensuring that the cables are fully in contact with the buffer layer 3. After checking that everything is correct, install the upper plate 1 and tighten it with connecting bolts and nuts so that the cable is completely in contact with the buffer layer 3 on the upper plate 1. The submersible pump is lowered by a hoisting device. During the descent of the submersible pump, the wire rope 5 moves synchronously with the hoisting device. During the lowering of the submersible pump and cable, the wire rope 5 is held at the shaft opening by other equipment or personnel, so that the section of the wire rope 5 lowered into the shaft is in a vertical state. After each section of descent in the shaft or pipeline, a set of clamping devices is installed at the top of the shaft. The above steps are repeated to ensure that the weight of the cable is evenly distributed until the submersible pump reaches the target installation position.

[0032] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
