Technical Field

[0001] The invention relates to the technical field of steelmaking equipment, and in particular to a sampling rod lifting and conveying device. Background Art

[0002] Steelmaking involves melting pig iron in a furnace according to a specific process, adjusting the composition of the slag during steelmaking, and producing steel. Steelmaking requires controlling carbon content, eliminating harmful elements, retaining or increasing beneficial elements, and adjusting the ratio of these elements to achieve optimal performance. Sampling measures the temperature of molten steel and collects samples before tapping. This provides temperature and chemical composition parameters for process control and serves as a crucial basis for operational control.

A few use simple lifting equipment to assist workers in lifting and transporting, but the rods need to be manually bundled and loaded and unloaded, which is time-consuming and labor-intensive. The rods are prone to falling, breaking, and injuring workers, resulting in low work safety. In order to improve work safety and efficiency, it is necessary to design and manufacture a sampling rod lifting and conveying device. Summary of the Invention

[0011] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a sampling rod lifting and conveying device includes a mounting frame 1, a lifting assembly 2 and a gripping assembly 3. The mounting frame 1 is a frame-shaped component, which is composed of a plurality of profiles. The lifting assembly 2 includes a driving motor 21, a driving shaft 22, a driven shaft 23 and a chain transmission mechanism 24. The driving motor 21 is fixedly mounted on the lower part of the mounting frame 1, and both ends of the driving shaft 22 are rotatably mounted on the lower part of the mounting frame 1 through bearing seats. The output shaft of the driving motor 21 is connected to the driving shaft 22, and both ends of the driven shaft 23 are rotatably mounted on the upper part of the mounting frame through bearing seats. The driven shaft 23 is arranged parallel to the driving shaft 22. The chain transmission mechanism is well known to those skilled in the art. The chain transmission mechanism 24 mainly includes a driving sprocket, a driven sprocket and a transmission chain. The two chain transmission mechanisms 24 are mounted in parallel on the driving shaft 22 and the driven shaft 23. On the upper part, the two driving sprockets are fixedly mounted on the driving shaft 22, and the two driven sprockets are fixedly mounted on the driven shaft 23. The grasping assembly 3 includes a fixed mounting plate 31, a fixed claw 32, a movable claw 33 and a spring 34. A plurality of fixed mounting plates 31 are evenly and parallelly arranged on the chain transmission mechanism 24.
