阅读说明：本技术 一种托钢轮 (Steel supporting wheel ) 是由 任吉堂 于 2020-05-18 设计创作，主要内容包括：本发明公开了一种托钢轮,属于热轧棒材穿水冷却设备领域,包括卡套在冷却器上的轮架和连杆,其特征在于轮架两侧的耳轴与两根平行连杆中部的孔铰接,连杆下部孔嵌入的工程塑料材质的滑动轴承对托起热轧棒材的托轮轴构成的约束；连杆上部孔与中部有径向贯穿螺孔的螺母销轴铰接,活节螺丝的螺纹端旋入螺母销轴的螺孔内,带孔的另一端则套在轮架上部两个凸起支点孔中的支点销轴上,组成了托钢轮的托轮高度调整机构。当热轧棒材在多个冷却器内孔依次高速通过时,其重量就落到了冷却器出口端的托轮上,且在托轮表面的V型槽侧壁的限制下,始终处于冷却器内孔的几何中心。既避免了冷却器内衬套的磨损,又确保了热轧棒材的均匀冷却。(The invention discloses a steel supporting wheel, belonging to the field of hot-rolled bar water cooling equipment, comprising a wheel carrier and a connecting rod which are clamped and sleeved on a cooler, and being characterized in that trunnions at two sides of the wheel carrier are hinged with holes at the middle parts of two parallel connecting rods, and a sliding bearing made of engineering plastics and embedded in a hole at the lower part of the connecting rod restrains a trunnion shaft for supporting the hot-rolled bar; the upper hole of the connecting rod is hinged with a nut pin shaft with a middle part radially penetrating through a screw hole, the thread end of the movable joint screw is screwed into the screw hole of the nut pin shaft, and the other end of the hole is sleeved on a fulcrum pin shaft in two raised fulcrum holes at the upper part of the wheel carrier, so that the riding wheel height adjusting mechanism of the steel riding wheel is formed. When the hot-rolled bar passes through the inner holes of the coolers at high speed in sequence, the weight of the hot-rolled bar falls onto the supporting roller at the outlet end of the cooler and is always positioned at the geometric center of the inner holes of the coolers under the limitation of the side wall of the V-shaped groove on the surface of the supporting roller. Not only avoids the abrasion of the inner bushing of the cooler, but also ensures the uniform cooling of the hot rolled bar.)
