[0002] A cable is a product consisting of one or more mutually insulated conductive cores covered with insulating materials and a protective layer. It is used to transmit electrical energy, signals or data. A cable pulling detection device is a professional device used to test the performance of a cable under a tensile load. This device is mainly used to detect the tensile strength, elongation, breaking strength and other mechanical performance parameters of the cable.

[0006] The technical solution is: a cable pulling detection device, including a mounting plate, a fixed head, a clamping piece and a protective shell. The left and right sides of the mounting plate are connected to two front and rear fixed heads, the fixed heads are connected to the clamping pieces through threads, and the rear side of the mounting plate is connected to the protective shell.

[0007] As a further preferred solution, the protective shell is made of stainless steel, which has higher hardness and strength.

[0008] As a further preferred solution, each clamping member is provided with a handle.

[0010] As a further preferred solution, it also includes a tension sensor and a hook, the front side of the right pull wire is connected to the tension sensor, and the front side of the tension sensor is connected to the hook.

[0011] As a further preferred solution, a display is also included, and the upper right side of the protective shell is connected to the display.

[0012] The utility model has the following advantages: 1. The utility model drives the pull wire to rotate through the motor on the left side, so that the left clamp moves to the left, and the cable is pulled laterally. The rear motor drives the pull wire on the rear side to pull the hook backward to pull the cable longitudinally, so that the cable can be pulled in different ways. It is easy to adapt to different situations of the cable, improve the flexibility of the use of the device, and improve the reliability of the cable pulling detection results.

[0018] A cable pulling detection device, such as Figure 1-Figure 2 As shown, it includes a mounting plate 1, a fixing head 2, a clamping member 3 and a protective shell 10. The left and right sides of the mounting plate 1 are connected to two front and rear fixing heads 2. The fixing heads 2 are connected to the clamping members 3 through threads. The clamping members 3 are provided with handles. The rear side of the mounting plate 1 is connected to the protective shell 10. The protective shell 10 is made of stainless steel and has high hardness and strength. It also includes a fixing block 4, a winding wheel 5, a pulling wire 6 and a motor 7. The rear side of the left part of the protective shell 10 is connected to the fixing block 4, and the front side of the left part of the mounting plate 1 is also connected to the fixing block 4. The fixed block 4 is rotatably connected to a winding wheel 5, and a pull wire 6 is wound around the winding wheel 5. The pull wire 6 on the right side passes through a protective shell 10, and a motor 7 is connected to the rear right side of the protective shell 10, and a motor 7 is also connected to the left front side of the protective shell 10.

[0019] When it is necessary to perform a pulling test on the cable, the device can be used. The clamping parts 3 are disengaged from each other by twisting the handle, and the cable is placed on the clamping parts 3. Then, the clamping parts 3 on the fixed head 2 are rotated in the opposite direction so that the clamping parts 3 contact each other to clamp the cable. Then, the motor 7 on the left side is started, and the winding wheel 5 on the left side is driven to rotate by the motor 7 on the left side, thereby driving the pull wire 6 on the left side to rotate, so that the clamping part 3 on the left side of the mounting plate 1 moves to the left, thereby pulling the cable laterally. After the pulling is completed, the motor 7 on the left side is turned off, and then the hook is hooked on the cable. The motor 7 on the rear side is started, and the winding wheel 5 on the rear side is driven to rotate by the motor 7 on the rear side, thereby driving the pull wire 6 on the rear side to rotate. The hook moves backwards, thereby pulling the cable longitudinally, so as to detect the pulling of the cable, which is convenient for adapting to different situations of the cable, improving the flexibility of the use of the device, and improving the reliability of the cable pulling detection results. After the pulling is completed, the motor 7 on the rear side is turned off, and the data of the pulling force is transmitted to the display 11 through the tension sensor 8, which is convenient for the operator to record and observe. When the cable breaks, the hook will be thrown out and restricted by the protective shell 10. The protective shell 10 is made of stainless steel and has high hardness and strength, so as to protect the operator, reduce the risk of injury to the operator, ensure the safety of the personnel, and improve the safety of operation.
