Description

Technical Field

[0001] The utility model relates to the technical field of steel bar stretching, in particular to a multifunctional steel bar stretcher with an infrared sensor. Background Art

[0002] In the field of construction engineering, a steel bar stretcher is a device used to stretch and shape steel bars. During the processing and use of steel bars, due to various factors (such as storage, transportation, processing errors, etc.), the steel bars often bend, twist, or have insufficient length. These problems not only affect the stress performance of the steel bars in the structure, but may also pose a potential threat to the safety of the overall structure. Therefore, stretching and straightening steel bars has become an important task in construction engineering. However, the existing steel bar stretchers are not accurate enough in positioning and stretching the steel bars, which affects the stretching accuracy and efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example

[0017] See also Figure 1-2 The utility model provides the following technical solutions: a multifunctional steel bar tensioner with an infrared sensor, comprising a hydraulic cylinder 9 and a tensioning mechanism 4, an active infrared sensor 12 is arranged above the front end of the hydraulic cylinder 9, and an infrared receiver is arranged on the outer surface of the tensioning mechanism 4.

[0018] Specifically, a hydraulic rod 3 is disposed on the inner side of the hydraulic cylinder 9 , and a stretching head 7 is disposed on one side of the hydraulic rod 3 .

[0019] Specifically, a containing pipe 5 is provided below the hydraulic cylinder 9 , and mounting frames 2 are provided on both sides of the containing pipe 5 .

[0020] Specifically, a fixing block 1 is disposed on the inner side of the mounting frame 2 , and a fixing slot 6 is disposed on the outer side of the mounting frame 2 .

[0022] Specifically, a protection device 11 is provided above the supporting device 8 , and alarm devices 10 are provided on both sides of the outer ends of the protection device 11 .

[0023] In this embodiment, the warning line composed of infrared beams plays a vital role in the multifunctional steel bar tensioner with active infrared sensor 12. Its main functions are as follows:

[0024] Object detection and location: The cordon is composed of a modulated infrared beam emitted by the active infrared sensor 12 transmitter. When a steel bar or other object enters this cordon area, it blocks part or all of the infrared beam. By detecting the blockage of the infrared beam, the sensor can accurately determine the presence of an object and its position in space.

[0025] Stretching control: In the application of multifunctional steel bar stretcher, the warning line is not only used to detect the position of the steel bar, but also to control the stretching process. When the steel bar is correctly placed within the warning line, the sensor will send a signal to the control unit to trigger the stretching mechanism to start the stretching action. By accurately controlling the stretching force and speed, it can ensure that the steel bar is stretched to the predetermined length and shape.

[0026] Enhanced safety: The setting of the cordon also enhances the safety of the operation process. When workers or other objects approach the cordon, the active infrared sensor 12 can immediately detect and trigger the safety warning device, emitting warning signals such as sound and light to remind workers to pay attention to safety and avoid accidental collision or injury.

[0027] Accuracy and stability: Due to the characteristics of infrared light beams such as straight-line propagation and susceptibility to interference, the warning line can provide accurate and stable object detection capabilities, which enables the multifunctional rebar tensioner to work accurately under various environmental conditions and improve the accuracy and reliability of tensioning.

[0028] The working principle and use process of the utility model are as follows: first, the stretching head 7 is started, and the active infrared sensor 12 starts working; then, the active infrared sensor 12 detects the position and shape of the steel bar, and sends a signal to the control unit; the control unit determines the position and shape of the steel bar according to the received signal, and controls the stretching mechanism to perform corresponding stretching actions; during the stretching process, the alarm device 10 monitors the surrounding environment in real time, and immediately sends out a warning signal once a worker or other object is found approaching the stretcher body.
