The invention relates to the field of lifting equipment, in particular to an examination lifting frame for animal husbandry veterinarians, which comprises a rack, a winch, a winding shaft, a bearing plate, a bearing rope and a brake device, one end of the bearing rope is fixed on the winch, the middle section is wound on the winding shaft, and the other end is connected with the bearing plate; the brake device is installed at the end of the winding shaft and comprises a trigger assembly, a driving plate, a limiting gear and a brake plate, the driving plate extends horizontally and can be installed on the rack in an up-down sliding mode, and the trigger assembly enables the driving plate to move upwards when the bearing rope is broken and the winding shaft suddenly accelerates; the outer side of the upper end of the brake plate can slide front and back with the driving plate and is rotationally connected around a rotating shaft extending front and back, a mounting groove is formed in the brake plate, and teeth are arranged on the inner side wall and the outer side wall of the mounting groove; when the bearing rope is broken, the triggering assembly enables the limiting gear to be meshed with the teeth on the inner side wall or the outer side wall of the mounting groove, so that when the driving plate drives the upper end of the brake plate to move upwards, the lower end of the brake plate rotates inwards around the limiting gear to prevent the winding shaft from rotating.

    本发明涉及提升设备领域,具体涉及一种畜牧兽医用检查升降架,包括机架、卷扬机、缠绕轴、承重板、承重绳和刹车装置,承重绳一端固定于卷扬机,中段缠绕于缠绕轴,且另一端与承重板连接;刹车装置安装于缠绕轴端部,包括触发组件、驱动板、限位齿轮和刹板,驱动板水平延伸,且可上下滑动地安装于机架,触发组件在承重绳断开,缠绕轴突然加速时使驱动板向上移动;刹板上端外侧与驱动板可前后滑动且绕前后延伸的转轴转动连接,刹板内设置有安装槽,安装槽的内侧壁和外侧壁上均设置有齿牙;承重绳断开时,触发组件使限位齿轮与安装槽内侧壁或外侧壁的齿牙啮合,以在驱动板带动刹板的上端向上移动时,刹板的下端绕限位齿轮向内转动阻碍缠绕轴转动。
