Description

Technical Field

[0001] This utility model relates to the field of steelmaking equipment technology, specifically to a sampling rod lifting and conveying device. Background Technology

[0002] Steelmaking refers to the process of melting pig iron in a steelmaking furnace according to a specific process, adjusting the composition of the slag in the steel and iron production, and producing finished steel. Steelmaking requires controlling carbon content, eliminating harmful elements, retaining or increasing beneficial elements, and adjusting the proportions between elements to obtain optimal performance. Sampling is conducted before tapping the molten steel to measure its temperature and collect samples, providing temperature and chemical composition parameters for process control and serving as a crucial basis for steelmaking operations.

[0003] Currently, the lifting and lowering of sampling rods mostly requires manual handling by workers on-site, which is labor-intensive and inefficient. A few use simple hoisting equipment to assist workers, but this still requires manual binding and unloading of the sampling rods, which is time-consuming and labor-intensive, and prone to accidents such as the sampling rods falling, breaking, or injuring workers, resulting in low work safety. Therefore, designing and manufacturing a sampling rod lifting and conveying device is essential to improve work safety and efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a sampling rod lifting and conveying device with a novel structure and practical function. It can realize one-to-one clamping and conveying of sampling rods, thereby improving conveying efficiency and safety.

The mounting frame 1 is a frame-shaped component, composed of multiple profiles connected together. The lifting assembly 2 includes a drive motor 21, a drive shaft 22, a driven shaft 23, and a chain transmission mechanism 24. The drive motor 21 is fixedly installed at the lower part of the mounting frame 1.

Two chain transmission mechanisms 24 are installed side by side on the drive shaft 22 and the driven shaft 23. On the 3rd, two driving sprockets are fixedly mounted on the driving shaft 22, and two driven sprockets are fixedly mounted on the driven shaft 23. The gripping assembly 3 includes a fixed mounting plate 31, a fixed claw 32, a movable claw 33, and a spring 34. Multiple fixed mounting plates 31 are evenly and parallelly arranged on the chain transmission mechanism 24. The two ends of the fixed mounting plate 31 are fixedly connected to two transmission chains respectively. Two fixed claws 32 are fixedly mounted on one fixed mounting plate 31. The movable claw 33 is hinged to the fixed claw 32 through a connecting pin 35. The fixed claw 32 and the movable claw 33 are provided with grooves that match the outer cylindrical surface of the sampling rod. The spring 34 is arranged between the fixed claw 32 and the movable claw 33, and its two ends are connected to the fixed claw 32 and the movable claw 33 respectively.

[0006] A further improvement is that anti-slip rubber pads are provided in the grooves on the fixed claw 32 and the movable claw 33.
