The invention belongs to the technical field of elevator equipment, and provides an elevator main machine multi-brake manual brake release device and a using method, the device comprises a crowbar mechanism, a pull rope piece and a plurality of brakes arranged on an elevator main machine, and a brake release operation mechanism is arranged on each brake. The brake release operating mechanism comprises a brake release connecting part, a brake release acting part and a brake release pulling part, the brake release pulling part comprises a brake release pull rod and an elastic assembly, acting force is applied to the brake release acting part by setting the compression amount of the elastic assembly, the tightening degree of the pull rope piece is adjusted, synchronous opening or asynchronous opening of a plurality of brakes can be achieved, and the brake release effect is improved. Opening operation of a plurality of brakes is operated through one crowbar mechanism, the number of operators is reduced, and therefore maintenance cost is saved, and the crowbar mechanism is reasonable in structural design, small in occupied space, low in production cost, high in universality and convenient to popularize.

    本发明属于电梯设备技术领域,提供一种电梯主机多制动器手动松闸装置及使用方法,装置包括撬棍机构、拉绳件和设于电梯主机上的多个制动器,所述制动器上设有松闸操作机构。所述松闸操作机构包括松闸连接部、松闸作用部和松闸拉动部,所述松闸拉动部包括松闸拉杆和弹性组件,通过设置弹性组件的压缩量来对松闸作用部作用力,而对拉绳件的绷紧度进行调节,可以实现多个制动器同步打开或者非同步打开,将多个制动器的打开操作通过一个撬棍机构操作,节省操作人员数量,从而节省维保成本,本方案的结构设计合理,占用空间小,生产成本低,通用性强,便于推广。
