Description

Technical Field

[0001] This utility model relates to the field of general underground transportation equipment, and more specifically, to an adjustable safety lifting beam for mining. Background Technology

[0002] During the installation of the support structure, the track of the cut-eye transport support needs to be adjusted. Based on the site conditions, after the adjustment, the angle of the previously installed high-speed lifting beam relative to the track changes due to the change in the track's centerline position. Since the existing lifting beam's anchoring points are fixed, resin anchor rods need to be reinstalled for repositioning, resulting in a cumbersome operation process, material waste, and a risk of runaway during use. Furthermore, the simple structure of the high-speed lifting beam lacks corresponding protective devices.

[0003] Chinese Utility Model Publication CN202323121883.5 discloses an adjustable safety lifting beam frame for mining, including a base plate, which serves as the assembly foundation for the equipment. The base plate has arrayed lifting holes on both sides; two rod supports are fixedly mounted on the top surface of the base plate, arranged in parallel; and a safety lifting rod is fixedly mounted on the top surface of each rod support. Compared to existing lifting beam frames, this utility model has a more rational design. The lifting holes on both sides allow for flexible adjustment of the anchoring point after track adjustment, ensuring the lifting beam frame runs in the center of the track. Furthermore, the safety lifting rod assists in pulling and lifting after the lifting beam runs away, preventing runaway accidents. However, in existing technologies, when the lifting beam needs to rotate, the base plate and rod supports must be disassembled, the angle adjusted, and then reinstalled, which is time-consuming, labor-intensive, and reduces work efficiency. Utility Model Content

[0004] This utility model aims to overcome the problem that when the lifting beam needs to be rotated, the base plate and the pole support need to be disassembled, the angle adjusted, and then reinstalled. It provides a lifting beam frame that can quickly change the direction of the lifting beam and improve work efficiency.

[0005] An adjustable safety lifting beam for mining is installed on the lifting beam body. It is characterized by including a fixed plate, a rotating connector, and a mounting column. The fixed plate is installed on both sides of the lifting beam body. The mounting column is movably and fixedly connected to the fixed plate. The mounting column is rotatably connected to the lifting beam body. The rotating connector is fixedly installed inside the mounting column. The mounting column is rotatably connected to the lifting beam body through the rotating connector.

[0006] Furthermore, the rotating connector is a bearing, which is embedded in the interior of the mounting column on the side away from the fixed plate. Connecting columns are fixedly installed at both ends of the lifting beam body, and the connecting columns are fixedly connected to the interior of the bearing.

[0007] Furthermore, the outer surface of the two connecting columns near the bearing is provided with external threads, and the inner surface of the bearing is provided with internal threads. The connecting columns and the inner surface of the bearing are connected by threads.

[0008] Furthermore, each of the two connecting columns is provided with a first connecting plate at one end near the end of the lifting beam body, and the first connecting plate is bolted to the end of the lifting beam body.

[0009] Furthermore, it also includes a second screw and a locking bolt. The mounting column is fixedly provided with an adjusting ear perpendicular to the direction of the lifting beam body. The adjusting ear has an adjusting hole. An extension plate is provided on the outside of the connecting column. The extension plate has a fixing hole. The adjusting ear passes through the adjusting hole and the fixing hole through the second screw, and the locking bolt is screwed into the second screw to connect with the extension plate.

[0010] Furthermore, it also includes a slide rod and a hydraulic cylinder. A slide groove is provided on the fixed plate, and the hydraulic cylinder is located at the bottom of the slide groove. The output end of the hydraulic cylinder is connected to the bottom of the slide rod. The slide rod is located on the side of the mounting column near the fixed plate, and the slide rod is slidably connected to the fixed plate.

[0011] Furthermore, it also includes a first screw and a nut. Long through holes are provided on both sides of the slide groove. The first screw passes through the slide rod and through the long through holes. The two ends of the first screw are connected to the nut.

[0012] Furthermore, it also includes ground nails, and the fixing plate has adjustable elongated holes, with the ground nails and the fixing plate being fixedly connected.

[0013] Furthermore, it also includes fixing bolts, and a second connecting plate is provided on the top of the ground nail, and the second connecting plate is connected to the fixing plate by fixing bolts.
