矿井运输工具安全制动器
本发明涉及用于控制自由下落运输工具的减速速率的矿井运输工具安全制动器，所述运输工具在竖直、基本竖直或倾斜矿井中的固定罐道内或上操作。所述安全制动器包括启动系统、能操作来用于锁定到一个或更多个罐道上的一个或更多个导件夹具组件、一个或更多个制动组件和附接在所述运输工具上的一个或更多个制动器路径部件。在检测到与所述运输工具的自由下落或受阻状况相关联的运输工具悬吊失效弛绳索条件时，所述启动系统被触发，从而使每个导件夹具组件自锁定到罐道上。在所述运输工具进一步向下行进时，所述制动组件在所述制动器路径部件上向上行进，从而以受控制的方式生成不断增加的制动力，直到所述运输工具达到受控制的停止。所述安全制动器本质上为纯机械的，因为没有涉及电子、电动机械控制或液压系统。
The disclosure relates to a mine shaft conveyance safety brake for controlling the rate of deceleration of a free-falling conveyance, operating within or upon fixed shaft guides, in a vertical, substantially vertical or inclined mine shaft. The safety brake includes an activation system, one or more guide clamp assemblies operable for locking onto one or more shaft guides, one or more braking assemblies and one or more brake paths attached upon the conveyance. Upon detection of a conveyance suspension failure or slack rope condition associated with a free-falling or obstructed condition of the conveyance, the activation system is triggered, causing each guide clamp assembly to self-lock onto a shaft guide. Upon further downward travel of the conveyance, the braking assemblies travel upwardly upon the brake paths, generating increasing braking forces in a controlled manner until the conveyance comes to a controlled stop. The safety brake is purely mechanical in nature, as there are no electronics, electro-mechanical controls or hydraulic systems involved.
