Technical Field
[0001] The utility model belongs to the technical field of fully mechanized mining working faces, and in particular relates to a laser straightening device for a hydraulic support straightness of a fully mechanized mining working face. Background Art
[0002] During fully mechanized coal mining operations, the straightness of hydraulic supports on the face often fails to meet standard requirements due to complex geological conditions, operational instability during mining, and other environmental factors. Substandard support straightness not only impacts smooth coal mining operations but can also lead to problems such as support jamming and substandard straightness. In severe cases, it can even cause electromechanical accidents, threatening coal mine safety. Therefore, precisely controlling the straightness of hydraulic supports and maintaining their stability is a key technical issue in coal mining.
[0003] Currently, the straightness control of hydraulic supports mostly relies on manual wire-pulling. While this method is simple to operate, it suffers from high labor intensity, low efficiency, and poor precision, making it difficult to meet the requirements for efficient production and safety during coal mining. Especially in complex fully mechanized mining face environments, manual methods cannot accurately and timely adjust the straightness of the supports, impacting the efficiency and safety of the entire production process. Therefore, the use of more accurate, efficient, and convenient equipment to monitor and adjust the straightness of hydraulic supports is urgently needed to improve production efficiency and ensure safe operations. Utility Model Content

Through laser technology, it can achieve precise control of the straightness of the hydraulic support, overcome the shortcomings of the traditional manual wire pulling method, improve the straightness adjustment efficiency and accuracy of the working face support, and ensure the smooth progress of the coal mining process.

The first infrared laser device emits a first infrared laser parallel to the chute roadway, the second infrared laser device and the third infrared laser device respectively emit a second infrared laser and a third infrared laser toward the middle hydraulic support, the second infrared laser intersects with the first infrared laser, and the third infrared laser is parallel to the second infrared laser.
[0006] Furthermore, the third infrared laser device is arranged on the inner side of the column.
[0007] Further, the third infrared laser device is fixed on the stand column through a fixing frame, and the fixing frame comprises a clamp, and the clamp is connected with a support base on the outside, and the third infrared laser device is fixed on the support base through screws.

Even in a harsh working environment, the installation and adjustment work can be quickly completed, and a large amount of labor cost and time is saved.
[0010] 2. The high-precision measurement and adjustment of the straightness of the support can be realized by using infrared laser technology, the error of traditional manual wire pulling is avoided, the straightness of the support meets the standard requirement, and the engineering quality problem and safety hazard caused by the non-standard straightness are reduced.
[0011] 3.
