Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical continuous casting equipment, specifically to a lifting baffle for a billet conveying roller conveyor. Background Technology

[0002] In metallurgical continuous casting production, the process of conveying steel billets on the conveying track needs to be controlled and guided to achieve functions such as accurate positioning, separation, or changing the conveying direction of the steel billets. Currently, the common technology is mainly to use hydraulic or pneumatically driven lifting baffles to block the steel billets. However, due to the harsh working conditions such as heavy load impact and high temperature, the service life of the equipment foundation and lifting baffle equipment is relatively short, which is not conducive to the efficient and smooth operation of the continuous casting production process. Utility Model Content

[0003] The purpose of this invention is to provide a lifting baffle for billet conveying rollers, which solves the problem of poor shock absorption and buffering effect of traditional lifting baffles in the prior art.

[0004] The technical solution adopted by this utility model is as follows: a lifting baffle for a billet conveying roller, including a fixed frame, a rotating plate hinged to the fixed frame, a lifting baffle hinged to the other end of the rotating plate, the middle part of the lifting baffle hinged to the rotating plate, a pair of buffers hinged to the bottom of the lifting baffle, the other ends of the two buffers being hinged to the bottom of the fixed frame, and a hydraulic cylinder support, the hydraulic cylinder support being fixed to the bottom of the fixed frame, a hydraulic cylinder hinged to the hydraulic cylinder support, the telescopic end of the hydraulic cylinder being hinged to the side of the rotating plate near the lifting baffle.

[0005] The features of this utility model also include:

[0006] The fixed frame includes a first side plate and a second side plate, which are arranged in parallel.

[0007] The top plate is fixedly connected to the top of the first side plate and the second side plate. One end of the top plate is fixedly connected to the first side plate, and the second side plate is located in the middle of the top plate.

[0008] The bottom of the first side plate and the second side plate are both fixedly connected to a base plate, one end of which is fixedly connected to the second side plate, and the first side plate is located in the middle of the base plate.

[0009] The fixed frame also includes two rotating plate support plates, one of which is fixed between the top plate and the first side plate, and the other rotating plate support plate is fixed between the top plate and the second side plate; the hydraulic cylinder support is fixed to the bottom plate.

[0010] The rotating plate includes a rotating plate body formed by four steel plates. Connecting rods are fixed to both sides of the rotating plate body. It also includes a hydraulic cylinder telescopic end support, which is fixed to the middle of the bottom edge of the rotating plate body.

[0011] The lifting baffle includes a trapezoidal plate, a channel steel is fixed to one side of the trapezoidal plate near the long bottom, and a pair of reinforcing plates symmetrically fixed to the trapezoidal plate. The reinforcing plates and the channel steel are arranged on the same side of the lifting baffle.

[0012] One side of the connecting rod is hinged to the rotating plate support plate, and the other side of the connecting rod is hinged to the middle of the reinforcing plate.

[0013] The buffer body is hinged to a buffer support, which is fixed to the bottom of the base plate.

[0014] One end of the hydraulic cylinder is hinged to the hydraulic cylinder support.

[0015] The other end of the hydraulic cylinder is hinged to the support of the hydraulic cylinder extension end.

[0016] The beneficial effects of this utility model are as follows: The lifting baffle of the billet conveying roller conveyor of this utility model is hydraulically driven, and the hydraulic system, including components such as an oil inlet pipe, an oil drain pipe, an oil return pipe, and a three-position four-way directional valve, controls the action of the hydraulic cylinder. During the lifting and lowering of the baffle, smooth buffering is achieved, absorbing the kinetic energy of the continuously cast billet, reducing impact load, and ensuring high positioning accuracy and reliable operation of the baffle.

[0017] It adopts a hinged connecting rod, with a reinforcing plate hinged to one end of the connecting rod. The lifting and lowering of the baffle is controlled by a hydraulic cylinder installed at the bottom.

[0018] A buffer is installed on the baffle. When the billet approaches the baffle, the buffer device can retreat a certain distance to prevent the billet from impacting the baffle and hydraulic cylinder, thus extending the service life of the equipment and providing a buffer and shockproof effect for the running billet.
