Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a tension-resistant cable. Background Art
[0002] Tensile cable, also known as tensile cable or high-strength cable, is a cable designed to withstand large tensile forces. This type of cable is usually used in situations where it is necessary to resist physical stress, vibration or external forces, such as construction sites, mines, tunnels, bridge construction, marine engineering, wind turbine towers, aerial work platforms, etc.
[0003] At present, in construction projects, cables are generally buried in the soil as needed to protect them from external damage. However, some soils have high moisture content and high humidity, which can cause the surface of the cable to become damp, leading to aging and damage of the insulating material, affecting the tensile properties of the cable itself. Secondly, microorganisms in the soil and soils with different pH values can also corrode the cables, affecting the tensile properties of the cables themselves. Utility Model Content
[0004] The purpose of the utility model is to provide a tensile-resistant cable to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A tensile-resistant cable comprises a cable body, a first shell and a second shell are arranged on the outside of the cable body, a plurality of rolling grooves are provided inside the first shell and the second shell along the circumferential direction, balls are installed in the rolling grooves, the balls are rollingly connected to the rolling grooves, the balls are in contact with the cable body, slide grooves are provided at both ends of the first shell and the second shell, the slide grooves are symmetrically arranged, a fixing component for fixing the first shell and the second shell is connected to the first shell, and sealing components for protecting the cable are connected at both ends of the first shell.
[0007] When the cable encounters easily corroded soil during burial, a first shell and a second shell are arranged on the outside of the cable and connected by a fixing component to prevent the soil from contacting the outer surface of the cable, thereby corroding the surface of the cable and affecting the tensile performance of the cable itself. Sealing components are arranged at both ends of the first shell to prevent moisture or microorganisms such as insects from entering the interior of the shell (the shell includes the first shell and the second shell) and causing harm to the cable body. Ball bearings are arranged inside the first shell and the second shell to reduce the friction between the shell and the cable body when the shell slides, thereby preventing the cable from being worn and causing a decrease in the tensile performance of the cable.
[0008] A further improvement of the technical solution of the utility model is that the fixing component includes a spring sheet, which is symmetrically arranged and fixedly connected to the first shell. A fixing block is fixedly connected to the first shell and is symmetrically arranged. A fixing groove and a clamping groove are symmetrically opened on the second shell, respectively. The fixing block is slidably connected to the fixing groove, and the spring sheet is slidably connected to the clamping groove.
[0009] The above technical solution is adopted. In this solution, when the first shell and the second shell need to be fixed on the surface of the cable, the fixing block is aligned with the fixing groove, and then the spring piece is pressed so that the spring piece and the slot slide and get stuck. At this time, the first shell and the second shell will clamp the cable in the middle to prevent the soil from contacting the cable body, thereby preventing the cable from being corroded and causing the tensile performance of the cable to decrease.
[0010] A further improvement of the technical solution of the utility model is that the sealing component includes a rotating block, which is respectively located at the two ends of the first shell and the second shell, the rotating block is slidably connected to the slide groove, and a sealing plate is fixedly connected to the side of the rotating block away from the slide groove, the sealing plate is in contact with the cable body, and adjacent rotating blocks are used in conjunction with each other.
[0011] The above technical solution is adopted. In this solution, when the first shell and the second shell need to be fixed, the rotating block is placed in the slide groove in advance, so that the rotating block and the slide groove are slidably connected, and then when the first shell and the second shell are fixed, the rotating block can be slid, thereby improving the fixing effect between the first shell and the second shell. At the same time, a sealing plate is provided on the rotating block to contact with the cable to prevent some insects and moisture in the soil from entering the shell to cause corrosion to the cable body, thereby effectively protecting the cable and preventing the cable from being corroded and causing the tensile performance of the cable to decrease.
[0012] A further improvement of the technical solution of the utility model is that a plurality of grooves are provided on one side of the first shell and the second shell away from the cable body.
[0013] The above technical solution is adopted, in which grooves are provided on one side of the first shell and the second shell to reduce the mass of the shell and prevent the shell from exerting excessive pressure on the cable body. Secondly, the grooves can increase the force of the soil on the shell, so that the shell is fixed more tightly and prevent the shell from swinging in the soil.
[0014] A further improvement of the technical solution of the utility model is that a sealing layer is arranged on one side of the first shell and the second shell close to the cable body, and the material of the sealing layer is silicone.
[0015] By adopting the above technical solution, a sealing layer is provided at the connection between the first shell and the second shell to prevent moisture and other microorganisms from passing through the gaps between the shells. At the same time, when the material of the sealing layer is rubber, the friction force generated when rubber contacts each other is large, which can enhance the fixing effect between the shells.
[0016] A further improvement of the technical solution of the utility model is that a plurality of protrusions are arranged on the surfaces of the first shell and the second shell on the side away from the cable body.
[0017] The above technical solution is adopted, in which a plurality of protrusions are arranged on the surface of the shell to increase the friction between the shell and the soil, so as to prevent the shell from moving and thereby increase the force on the cable, so as to better protect the cable.
[0018] A further improvement of the technical solution of the utility model is that the outer surfaces of the first shell and the second shell are painted with an anti-corrosion paint layer.
[0019] By adopting the above technical solution, an anti-corrosion paint layer is provided on the outer side of the shell, which can delay the corrosion of the shell by the soil, thereby extending the service life of the shell.
[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0021] 1. The utility model provides a tensile-resistant cable. When the cable is buried in soil that is easily corroded, a first shell and a second shell are arranged on the outside of the cable and connected by a fixing component to prevent the soil from contacting the outer surface of the cable, thereby corroding the surface of the cable and affecting the tensile performance of the cable itself. Sealing components are arranged at both ends of the first shell to prevent moisture or microorganisms such as insects from entering the inside of the shell (the shell includes the first shell and the second shell) to cause harm to the cable body. Ball bearings are arranged inside the first shell and the second shell to reduce the friction between the shell and the cable body when the shell slides, thereby preventing the cable from being worn and causing a decrease in the tensile performance of the cable.
[0022] 2. The utility model provides a tensile-resistant cable. When the first shell and the second shell need to be fixed on the surface of the cable, the fixing block is aligned with the fixing groove, and then the spring piece is pressed so that the spring piece and the slot slide and get stuck. At this time, the first shell and the second shell will clamp the cable in the middle to prevent soil from contacting the cable body, thereby preventing the cable from being corroded and causing the tensile performance of the cable to decrease.
[0023] 3. The utility model provides a tensile-resistant cable. When the first shell and the second shell need to be fixed, the rotating block is placed in the slide groove in advance so that the rotating block and the slide groove are slidably connected. Then, when the first shell and the second shell are fixed, the rotating block can be slid, thereby improving the fixing effect between the first shell and the second shell. At the same time, a sealing plate is provided on the rotating block to contact with the cable to prevent some insects and moisture in the soil from entering the shell to cause corrosion to the cable body, thereby effectively protecting the cable and preventing the cable from being corroded, which causes the tensile performance of the cable to decrease.

[0032] The present invention is further described in detail below in conjunction with the embodiments:
[0033] like Figure 1 , Figure 4As shown, the utility model provides a tensile-resistant cable, including a cable body 1, a first shell 2 and a second shell 3 are arranged on the outside of the cable body 1, a plurality of rolling grooves 4 are opened inside the first shell 2 and the second shell 3 along the circumferential direction, balls 5 are installed in the rolling grooves 4, the balls 5 are rollingly connected with the rolling grooves 4, the balls 5 are in contact with the cable body 1, slide grooves 6 are opened at both ends of the first shell 2 and the second shell 3, the slide grooves 6 are symmetrically arranged, a fixing component for fixing the first shell 2 and the second shell 3 is connected to the first shell 2, and a sealing component for protecting the cable is connected to both ends of the first shell 2.
[0034] In this embodiment, when the cable encounters easily corroded soil during burial, a first shell 2 and a second shell 3 are provided on the outside of the cable and connected by a fixing component to prevent the soil from contacting the outer surface of the cable, thereby corroding the surface of the cable and affecting the tensile strength of the cable itself. Sealing components are provided at both ends of the first shell 2 to prevent moisture or microorganisms such as insects from entering the interior of the shell (the shell includes the first shell 2 and the second shell 3) and causing harm to the cable body 1. Ball bearings 5 are provided inside the first shell 2 and the second shell 3 to reduce the friction between the shell and the cable body when the shell slides, thereby preventing the cable from being worn and causing a decrease in the tensile strength of the cable.
[0035] like Figure 3 As shown, in this embodiment, preferably, the fixing component includes a spring piece 7, which is symmetrically arranged, and the spring piece 7 is fixedly connected to the first shell 2. A fixing block 8 is fixedly connected to the first shell 2, and the fixing block 8 is symmetrically arranged. A fixing groove 10 and a card slot 9 are symmetrically opened on the second shell 3, respectively, and the fixing block 8 is slidably connected to the fixing groove 10, and the spring piece 7 is slidably connected to the card slot 9.
[0036] When the first shell 2 and the second shell 3 need to be fixed on the surface of the cable, the fixing block 8 is aligned with the fixing groove 10, and then the spring piece 7 is pressed so that the spring piece 7 and the card slot 9 slide and get stuck. At this time, the first shell 2 and the second shell 3 will clamp the cable in the middle to prevent the soil from contacting the cable body 1, thereby preventing the cable from being corroded and causing the tensile performance of the cable to decrease.
[0037] like Figure 1 , Figure 6 As shown, preferably, the sealing component includes a rotating block 11, which is respectively located at the two ends of the first shell 2 and the second shell 3, the rotating block 11 is slidably connected to the slide groove 6, and a sealing plate 12 is fixedly connected to the side of the rotating block 11 away from the slide groove 6, the sealing plate 12 is in contact with the cable body 1, and adjacent rotating blocks 11 are used in conjunction with each other.
[0038] When the first shell 2 and the second shell 3 need to be fixed, the rotating block 11 is placed in the slide groove 6 in advance, so that the rotating block 11 is slidably connected with the slide groove 6, and then when the first shell 2 and the second shell 3 are fixed, the rotating block 11 can be slid, thereby improving the fixing effect between the first shell 2 and the second shell 3. At the same time, a sealing plate 12 is provided on the rotating block 11 to contact with the cable to prevent some insects and moisture in the soil from entering the shell to cause corrosion to the cable body 1, thereby effectively protecting the cable and preventing the cable from being corroded and causing the tensile performance of the cable to decrease.
[0039] like Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, a plurality of grooves 13 are provided on the side of the first shell 2 and the second shell 3 away from the cable body 1 .
[0040] In this embodiment, a groove 13 is provided on one side of the first shell 2 and the second shell 3 to reduce the mass of the shell and prevent the shell from exerting excessive pressure on the cable body 1. Secondly, the groove 13 can increase the force of the soil on the shell, so that the shell is fixed more tightly and prevent the shell from swinging in the soil.
[0041] like Figure 3 As shown, based on Example 2, the utility model provides a technical solution: preferably, a sealing layer 14 is provided on one side of the first shell 2 and the second shell 3 close to the cable body 1, and the material of the sealing layer 14 is silicone.
[0042] In this embodiment, a sealing layer 14 is provided at the connection between the first shell 2 and the second shell 3 to prevent moisture and other microorganisms from passing through the gaps between the shells. At the same time, when the sealing layer 14 is made of rubber, the friction force generated when rubber contacts each other is relatively large, which can enhance the fixing effect between the shells.
[0043] like Figure 4 As shown, based on Example 3, the utility model provides a technical solution: preferably, a plurality of protrusions are provided on the surface of the first shell 2 and the second shell 3 away from the cable body 1.
[0044] In this embodiment, by providing a plurality of protrusions on the surface of the shell, the friction between the shell and the soil can be increased to prevent the shell from moving and thus increase the force on the cable, thereby better protecting the cable.
[0045] like Figure 1 As shown, preferably, the outer surfaces of the first shell 2 and the second shell 3 are coated with an anti-corrosion paint layer.
[0046] By providing an anti-corrosion paint layer on the outer side of the shell, the corrosion of the shell by the soil can be delayed, thereby extending the service life of the shell.
[0047] The following is a detailed description of the working principle of the tensile cable.
[0048] like Figure 1-6 As shown, when the cable encounters soil that is easily corroded during burial, the first shell 2 and the second shell 3 are connected by a fixing component on the outside of the cable to prevent the soil from contacting the outer surface of the cable, thereby corroding the surface of the cable and affecting the tensile performance of the cable itself. By providing sealing components at both ends of the first shell 2, moisture or microorganisms such as insects can be prevented from entering the interior of the shell (the shell includes the first shell 2 and the second shell 3) to cause harm to the cable body 1. By providing a ball 5 inside the first shell 2 and the second shell 3 to reduce the friction between the shell and the cable body when the shell slides, the cable is prevented from being worn and causing the tensile performance of the cable to decrease. When the first shell 2 and the second shell 3 need to be fixed on the surface of the cable, the fixing block 8 is aligned with the fixing groove 10, and then the spring piece 7 is pressed so that the spring piece 7 slides and is stuck with the card slot 9. At this time, the first shell 2 and the second shell 3 will clamp the cable in the middle to prevent the soil from contacting the cable body 1, thereby preventing the cable from being corroded and causing the tensile performance of the cable to decrease. When the first shell 2 and the second shell 3 need to be fixed, the rotating block 11 is placed in the slide groove 6 in advance so that the rotating block 11 is slidably connected with the slide groove 6. Then, when the first shell 2 and the second shell 3 are fixed, the rotating block 11 can be slid, thereby improving the fixing effect between the first shell 2 and the second shell 3. At the same time, a sealing plate 12 is provided on the rotating block 11 to contact with the cable to prevent some insects and moisture in the soil from entering the shell to corrode the cable body 1, thereby effectively protecting the cable and preventing the cable from being corroded and causing the tensile performance of the cable to decrease. When a groove 13 is provided on one side of the first shell 2 and the second shell 3, in order to reduce the mass of the shell, the pressure of the shell on the cable body 1 is prevented from being too large. Secondly, the groove 13 can increase the force of the soil on the shell, so that the shell is fixed more tightly and prevent the shell from swinging in the soil. By providing a sealing layer 14 at the connection between the first shell 2 and the second shell 3, microorganisms such as moisture can be prevented from passing through the gap between the shells. At the same time, when the material of the sealing layer 14 is rubber, the friction generated when rubber and rubber contact each other is large, which can enhance the fixing effect between the shells. By providing a plurality of protrusions on the surface of the shell, the friction between the shell and the soil can be increased to prevent the shell from moving, thereby increasing the force on the cable and better protecting the cable. By providing an anti-corrosion paint layer on the outside of the shell, the corrosion of the shell by the soil can be delayed, thereby extending the service life of the shell.
[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
