Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a cable tensile testing device. Background Art

[0002] In cable manufacturing and quality control, cable tensile strength is a crucial performance indicator. It directly impacts the durability and reliability of cables in practical applications. To accurately assess a cable's tensile strength, specialized testing equipment is required to simulate the cable's tensile state and measure the maximum tensile force it can withstand.

[0003] Traditional cable tensile testing equipment often has some shortcomings, such as unstable testing process, imprecise pressure application method, and difficulty in accurately measuring the tensile force on the cable. These problems may lead to inaccurate test results, thus affecting the judgment of cable quality. Utility Model Content

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0026] like Figure 1 and Figure 2 As shown, the cable tensile testing equipment of the present practical design is characterized in that it comprises two groups of relatively arranged cable support seats 1; a cable bearing roller 2 is installed on the cable support seat 1; a lifting platform 3 and a lifting mechanism 4 connected to the lifting platform 3 are arranged between the two groups of cable support seats 1; a cable pressure seat 5 is mounted on the lifting platform 3, and a cable pressure roller 5.1 for contacting the cable is provided on the cable pressure seat 5; a cable clamp 6 for fixing the cable is also arranged on one side of each cable support seat 1.

[0027] As an embodiment, a winding post 7 is arranged adjacent to the cable clamp 6 , and a spiral anti-slip groove 7 . 1 is provided on the outer surface of the winding post 7 .

[0028] The primary function of the winding post 7 is to guide the cable, maintaining a defined path and shape during testing. Positioning the winding post adjacent to the cable clamp 6 ensures that the cable moves in the desired direction when subjected to tension, minimizing twisting and irregular deformation. The anti-slip groove effectively grips the cable surface, preventing it from slipping or falling off when subjected to tension.

[0029] As an embodiment, the lifting mechanism 4 includes:

[0030] A plurality of wire holders 4.1 are provided on the lifting platform 3;

[0031] A screw rod 4.2 is connected to the screw seat 4.1;

[0032] A commutator 4.3 connected to the input end of the screw 4.2;

[0033] A drive shaft 4.4 connected to the input end of the commutator 4.3;

[0034] A motor drive 4.5 connected to the drive shaft 4.4.

[0035] The motor drive 4.5 serves as the power source for the entire lifting mechanism, providing the necessary rotational force. When activated, it rotates the connected drive shaft 4.4. Through motor drive, direction-changing speed regulation, transmission conversion, and precise control, the position of the lifting platform can be precisely adjusted, thus meeting the requirements for the magnitude and direction of the tensile force during cable tensile testing.

[0036] As an embodiment, a plurality of guide rods 8 are installed under the cable pressure seat 5 and are slidably matched with the lifting platform 3. The provision of the guide rods 8 enables the cable pressure seat 5 to move smoothly along a predetermined trajectory during the lifting process, thereby reducing the test error caused by deviation or shaking.

[0037] Specifically, a pressure detection seat 9 is provided between the lifting platform 3 and the cable pressure seat 5 , and a pressure sensor for detecting the downward pressure of the cable pressure seat 5 is provided in the pressure detection seat 9 .

[0038] The pressure detection seat 9 is located between the lifting platform 3 and the cable pressure seat 5, and plays the dual role of bridge and monitoring. It can not only support the cable pressure seat, but also detect and feedback the downward pressure applied by the cable pressure seat to the cable in real time.

[0039] The pressure sensor is the core component of the pressure test seat. It can convert the pressure applied by the cable pressure seat to the cable into an electrical signal and display it through the data processing system. In this way, the tester can intuitively understand the real-time changes in the tension of the cable during the test.

[0040] As an embodiment, the cable pressure roller 5.1 and the cable support roller 2 have diameters that taper from both ends toward the center. Since the rollers are narrower at both ends and wider in the center, when they press on the cable, they can ensure that the cable's force-bearing surface is more uniform, avoiding the situation of excessive local pressure.

[0041] The working principle of this utility model is as follows:

[0042] Stable Support: The equipment uses two sets of oppositely positioned cable support bases 1, providing a stable support platform for the cable. Cable bearing rollers 2 installed on the support bases effectively reduce friction between the cable and the support bases during the test, protecting the cable surface and ensuring the accuracy of the test results.

[0043] Precise Pressure: A lift platform 3 is installed between the two sets of cable supports. This lift platform is precisely controlled by a connected lifting mechanism 4. The lifting mechanism utilizes the precise coordination of components such as the motor, drive shaft, commutator, and lead screw to achieve smooth lifting and lowering of the lift platform, thereby precisely controlling the tension applied to the cable.

[0044] Contact Pressure: A cable pressure roller 5.1, designed specifically for contacting the cable, is mounted on a cable pressure seat 5 mounted on the lifting platform. This roller acts directly on the cable, applying tension to the cable through the lifting platform's upward and downward motion. The roller's design helps evenly distribute tension, reducing localized stress concentration in the cable and ensuring the reliability of test results.

[0045] Cable Fixing: To prevent the cable from sliding or falling off during the test, a cable clamp 6 is provided on one side of each cable support. These clamps can firmly fix both ends of the cable, ensuring that the cable can maintain a stable posture when subjected to tension, thereby improving the accuracy and safety of the test.

[0046] It should be noted that, in this article, the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise expressly specified and limited, the terms "install", "connect", and "connect" 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 an indirect connection through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0048] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
