Description

Technical Field

[0001] The present application relates to the technical field of cable processing, and in particular to an oil filling machine and an oil filling method. Background Art

[0002] With the rapid growth of my country's national economy, especially the accelerated pace of rural and urban power grid construction and transformation and the rapid development of communication technology in real estate industries in various places, my country's power industry has developed rapidly, thereby promoting the development of the electrical industry, especially the wire and cable industry, which is compatible with the power industry, and promoting the widespread application of digital communication cable products. At the same time, in order to cope with a wide range of applicable occasions and methods, the variety of wires and cables has shown a diversified trend, and the requirements for water blocking of wires and cables have undergone earth-shaking changes in recent years: the requirements for water blocking were previously limited to the application of submarine cables, ultra-high voltage cables and communication cables, but with the deepening of research and understanding of insulation water absorption and water trees, people are increasingly aware of the importance of waterproof performance for medium and high voltage wires and cables. In areas with high groundwater levels or perennial rainy areas (such as the area south of the Yangtze River in my country), more and more users and various regional occasions have put forward waterproof requirements for cables. With the development of time, water-blocking wires and cables have become an important branch of water-blocking cable products. In addition to their original functions and occasions, they are now mainly used outdoors. In windy and rainy weather and humid seasons, they can prevent water vapor and moisture from entering the cable, allowing it to maintain good transmission performance.

[0003] In order to improve the water blocking performance of the cable, in the prior art, water blocking grease is often filled into the gaps in the cable core to achieve longitudinal water blocking. Figure 1 As shown, it includes an oil tank 1, an oil filling pipe 2, an oil storage tank 4 and a pressurizing device 5. The oil tank 1 is used to pass the wire to be filled with oil. The oil filling pipe 2 is arranged between the oil tank and the oil storage tank 4. The oil storage tank 4 is used to store the ointment. The pressurizing device 5 is arranged above the oil storage tank 4. In the process of the wire to be filled with oil passing through the oil tank 1, the pressurizing device 5 applies a downward pressure to the ointment in the oil storage tank 4, so that the ointment enters the oil tank 1 through the oil filling pipe 2 and adheres to the surface of the wire. For this, it is necessary to continuously input the ointment into the oil storage tank 4. In this technical solution, an oil inlet 3 is opened in the middle of the oil filling pipe 2, and the oil inlet 3 is used to connect the refueling pipeline to continuously replenish the ointment into the oil storage tank 4. However, the ointment is added from the oil filling pipe 2, resulting in the mixing of the oil outlet channel and the oil inlet channel of the oil storage tank 4, which in turn leads to the instability of the oil filling pressure, so that the ointment cannot be evenly attached to the surface of the wire, and it is easy to cause bulging and other situations, which urgently needs to be improved. Summary of the invention

[0004] The purpose of the present application is to provide an oil filling machine and an oil filling method to solve the problem of unstable oil filling pressure caused by replenishing ointment in the prior art.

In addition, the terms "one", "first", "second", "third", "fourth", "fifth", "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0038] Figure 2 The specific structure of an oil filling machine in this application is shown. Figure 3 yes Figure 2 Side view of the Figure 2-3As shown, the oil filling machine includes an oil tank 1, an oil filling pipe 2, an oil storage tank 4 and a pressurizing device 5. The oil tank 1 is used to pass the wire to be filled with oil. The oil filling pipe 2 is arranged between the oil tank and the oil storage tank 4. The oil storage tank 4 is used to store the ointment. The pressurizing device 5 is arranged above the oil storage tank 4. In the process of the wire to be filled with oil passing through the oil tank 1, the pressurizing device 5 applies a downward pressure to the ointment in the oil storage tank 4, so that the ointment enters the oil tank 1 through the oil filling pipe 2 and adheres the ointment to the surface of the wire. For this reason, it is necessary to continuously input the ointment into the oil storage tank 4, so the present application sets a refueling pipe 6 at the bottom of the oil storage tank 4, and the refueling pipe 6 is arranged on the side of the oil filling pipe 2, so that the oil inlet channel and the oil outlet channel to the oil storage tank 4 are staggered.

[0039] In the above technical scheme, the present application sets a refueling pipe 6 at the bottom of the oil storage tank 5, and the refueling pipe 6 is located on the side of the oil filling pipe 2, so that the oil inlet channel and the oil outlet channel to the oil storage tank 4 are staggered. Different from the prior art where the channels for replenishing oil and the channels for discharging oil are mixed, the replenishing oil will not affect the filling pressure of the oil filling device, so that the oil can be evenly adhered to the surface of the wire to avoid bulging and the like.

[0040] In the above technical solution, a wire inlet die 12 and a wire outlet die 13 are provided at both ends of the oil tank 1 to guide the wires to pass in and out.

[0041] Secondly, the pressurizing device 5 is a hydraulic cylinder or an oil cylinder, and the pressurizing device has a telescopic rod, which is inserted into the oil storage tank 4, and the oil paste in the oil storage tank 4 is pressurized by the downward pressure of the telescopic rod.

[0042] In addition, an oil collecting box is provided below the oil tank 1, and the excess oil in the oil tank 1 flows out from both ends of the oil tank 1 and falls into the oil collecting box. Furthermore, a filter screen can be provided at the upper end of the oil collecting box to filter out impurities mixed in the recovered oil.

[0043] Furthermore, the ointment involved in the present application generally has thixotropic properties, that is, its fluidity can be increased by stirring. Therefore, the present application sets a rotating mechanism 7 in the oil storage tank 4 to enable the ointment to flow into the oil tank 1 more smoothly and to make the ointment more evenly distributed in the oil tank 1.

[0044] Figure 4 The specific structure inside the oil storage tank 4 is shown. Figure 5 is a schematic structural diagram of the rotating mechanism 7, Figure 6 is a schematic diagram of the rotation action of the rotating mechanism 7, Figure 7 This is a schematic diagram of the stirring action of the oil filling mechanism. Figure 4-6As shown, the rotating mechanism 7 is arranged at the lower end of the telescopic rod of the pressurizing mechanism 5 and is rotationally connected to the telescopic rod. When the telescopic rod moves up and down in the oil storage tank 4, it can drive the rotating mechanism 7 to rotate, thereby stirring the ointment located below the rotating mechanism 7.

[0045] Specifically, the rotating mechanism 7 includes a cylindrical structure that matches the shape of the telescopic rod. A pressing plate 71 is provided below the rotating mechanism 7. The shape of the pressing plate 71 matches the shape of the inner cavity of the oil storage tank 4. The pressing plate 71 is used to squeeze the oil rod. The pressing plate 71 is fixedly connected to the end of the rotating mechanism 7, and the rotating mechanism 7 can drive the pressing plate 71 to rotate. A stirring blade 72 is provided in the middle of the lower end of the pressing plate 71. The stirring blade 72 is fixedly connected to the pressing plate 71, driving the stirring blade 72 to rotate, thereby stirring the ointment.

[0046] Furthermore, the rotating mechanism 7 is a hollow structure, and a slide bar 74 is arranged inside the rotating mechanism 7, and the slide bar 74 is placed obliquely relative to the rotating axis of the rotating mechanism 7. A vertical opening is arranged on the side wall of the rotating mechanism 7, and the height of the opening is consistent with the vertical height of the slide bar 74. A fixing member 73 is arranged on the inner wall of the oil storage tank 4, and a guide rod is arranged at the front end of the fixing member 73, and the guide rod extends into the interior of the rotating mechanism 7 through the above-mentioned opening. A sliding sleeve 75 is arranged at the front end of the guide rod, and a through hole is arranged inside the slide bar 75, and the through hole and the slide bar 74 are inclined at the same angle, so that the sliding sleeve 75 is sleeved on the slide bar 74.

[0047] In the above technical solution, when the telescopic rod moves downward, the rotating mechanism 7 is driven to move downward, so that the sliding sleeve 75 moves upward relative to the sliding bar 74. Since the sliding bar 74 is placed at an angle, when the sliding sleeve 75 moves on the sliding bar 74, its relative position with the rotating axis of the rotating device 7 changes. However, since the sliding sleeve 75 is fixedly arranged on the fixing member 73 and cannot move, the rotating device 7 rotates.

[0048] Finally, the present application also discloses an oil filling method based on the above oil filling machine, comprising the following steps:

[0049] Refilling the oil: Refill the oil into the oil storage tank 4 through the filling pipe 6;

[0050] Filling oil, applying pressure through a pressure device to press the oil paste in the oil storage tank 4 into the oil tank 1;

[0051] Wire passing: Pass the wire through the oil tank 1 so that the oil paste is evenly attached to the surface of the wire.

[0052] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
