Description

Technical Field

[0001] The utility model belongs to the technical field of steel rolling equipment, and in particular relates to a steel rolling billet rejecting device. Background Art

[0002] In steel rolling production, wires, bars and steel sections are heated in a heating furnace and then enter the roller area in front of the furnace, where they are sent to the next process via conveyor rollers. Raw steel billets that do not meet the processing temperature requirements often appear in the roller area in front of the furnace and need to be removed for reheating. Therefore, it is very necessary to configure corresponding equipment to remove or remove the steel billets.

[0003] Traditionally, a crane is used to suspend the rope and use the rope to move the steel billet. This method is prone to cause safety accidents due to unstable lifting during the steel billet lifting process.

[0004] The patent with publication number CN107695112A discloses a device for removing steel billets on a rolling mill roller conveyor. In the device, the oil cylinder base and the steel throwing stand are located on the same side of the roller conveyor, the oil cylinder base is below the steel throwing stand, the cylinder body of the oil cylinder is connected to the oil cylinder base through a rotating shaft, the connecting rod shaft seat is fixedly mounted on the steel throwing stand, the connecting rod is mounted on the connecting rod shaft seat through the connecting rod rotating shaft, one end of the connecting rod is rotatably connected to the front end of the oil cylinder push rod, the other end of the connecting rod is located between the two rollers of the roller conveyor, and the upper surface of the connecting rod is lower than the roller surface. The device realizes the removal of steel billets, but in the removal process, the device needs to first lift the steel billet, and then the steel billet slides down under the action of gravity. However, for heavy steel billets, the lifting process requires a large force to be applied, and the sliding of the steel billet will also bring a large impact, causing loss to the device.

[0008] Optionally, a material receiving platform is provided on the side of the conveying roller facing away from the telescopic rod, and the material receiving platform is provided on the belt conveyor.

[0009] Optionally, the receiving platform is flush with the top end of the conveying roller, and a top block is provided at the front end of the pusher claw, and the top block is used to push the steel billet onto the conveyor belt.

[0010] Optionally, two front and rear pulleys are provided under the pusher claw, the pulleys are slidably connected to the track, and the pulley close to the push rod is hinged to the push rod.

[0011] Optionally, a bracket is further included, on which a track bracket is arranged, and the track is arranged on the track bracket.

[0012] Optionally, the telescopic rod adopts an electro-hydraulic push rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model utilizes a telescopic rod to drive the connecting rod to rotate, and the push rod pushes the push claw under the drive of the connecting rod. The push claw is provided with front and rear pulleys, and the pulley on the side of the push claw close to the push rod is hinged to the push rod, so that the push claw can move along the horizontal track and push the steel billet horizontally, avoiding the loss of the device caused by excessive force in the process of lifting the steel billet or the impact of the steel billet sliding off. After the steel billet is pushed horizontally to the receiving platform, it moves along the conveyor belt on the belt conveyor, which is convenient for timely removal of the steel billet; the multi-point support of the driving device by the base and the track bracket enhances the stability of the driving device.
