Description

Technical Field

[0001] The utility model relates to the technical field of power systems, in particular to a wire tensioning device. Background Technique

[0002] In the power system, the tensioning and fixing of wires are key links to ensure the stability and safety of power transmission. At present, most of the wire tensioning devices widely used in the market adopt mechanical springs or hydraulic devices to achieve the automatic adjustment and fixing of wires. However, these existing technical solutions have several significant disadvantages:

[0003] 1. Mechanical spring type device: Although the structure is simple, the spring is prone to fatigue after long-term use, resulting in unstable tension force. The spring needs to be frequently replaced, increasing the maintenance cost and difficulty.

[0004] 2. Hydraulic type device: Although it can provide relatively stable tension force, the system is complex, has high requirements for the quality of the oil, is prone to oil leakage, causing environmental pollution, and is sensitive to changes in environmental temperature, affecting the use effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wire tensioning device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A wire tensioning device, including a base, a slider and a servo motor. A top cover is arranged on the top of the base. Side plates are installed on both sides of the base. A servo motor is arranged on one side inside the base. The output end of the servo motor is installed with a precision lead screw, and one end of the precision lead screw is installed with the side plate through a bearing. A slider is slidably installed inside the base. An installation sleeve is installed on the top of the slider. A force sensor is built in the installation sleeve. The slider is penetrated by the precision lead screw.

[0007] When this device is in use, the device is fixed at a designated position, the cable is penetrated through the installation sleeve and fixed. When tensioning is required, the servo motor is started to drive the precision lead screw to rotate. When the precision lead screw rotates, it will drive the slider to move, and then drive the installation sleeve to move. The staff can precisely adjust the wire tension force by controlling the rotation angle and speed of the servo motor. Because a force sensor is built in the installation sleeve, it can monitor the wire tension force in real time and transmit the data to the backend control system, which is convenient to adjust the output parameters of the servo motor according to parameters such as environmental temperature, wire material and length, to ensure that the best tension state of the wire can be maintained under different working conditions, realizing closed-loop control. It adopts a grease-free lubrication design to avoid environmental pollution; key components are selected from high-strength and corrosion-resistant materials to extend the service life and reduce the replacement frequency.

[0008] Preferably, a sliding hole is opened inside the top cover.

[0009] The sliding hole can facilitate the movement of the installation sleeve, thereby preventing the top cover from interfering with the movement of the installation sleeve.

[0010] Preferably, the mounting sleeve extends to the outside of the sliding hole.

[0011] Because the installation sleeve extends to the outside of the sliding hole, the sliding hole can provide protection for the base while facilitating the installation sleeve to fix the appropriate wire.

[0012] Preferably, the servo motor adopts a servo system.

[0013] Because the servo motor uses a servo system, its position, speed and acceleration can be accurately controlled to achieve high-precision motion control.

[0014] In summary, this application has the following beneficial technical effects:

[0015] This utility model realizes precise control of the tensioning force through the combination of a servo motor and a precision lead screw, ensuring that the wire is in the optimal stress state for a long time. Because the installation sleeve has a built-in force sensor, the wire tensioning force is monitored in real time, and the output parameters of the servo motor can be adjusted conveniently according to changes in parameters such as ambient temperature, wire material and length, ensuring that the optimal tensioning state of the wire can be maintained under different working conditions, realizing closed-loop control, while the oil-free design reduces environmental pollution, and the intelligent adjustment reduces unnecessary energy consumption.
