Emergency standby device for fire-fighting door closer
The invention relates to the technical field of fire-fighting equipment, and discloses a fire-fighting door closer emergency standby device which comprises a shell, a bearing and a first gear, the bearing penetrates through and is clamped in the center area of the top of the shell, the first gear is fixedly installed at the top end of the bearing, and the bearing is fixedly sleeved with a rope disc, a second gear and a resistance disc in sequence from the top end to the bottom end; the right side of the bearing is fixed to a fixing frame at the top of an inner cavity of the shell, a pulley is fixedly installed at the bottom end of the fixing frame, an electromagnetic device is fixedly installed at the bottom of the inner cavity of the shell, the rope disc is fixedly connected with a rope, and the tail end of the rope is fixedly connected with a permanent magnet after the rope turns through the pulley. The standby fire-fighting hydraulic device is a standby device capable of enabling a fire-fighting door to be normally used after the hydraulic device loses functions, meanwhile, unique electromagnetic attraction is matched with the pressure of a friction block I and a friction block II on a rope so that the door can be opened in a labor-saving mode and closed at a constant speed, and the standby fire-fighting hydraulic device has the function of tightly closing the door through strong attraction force in a fire disaster.
本发明涉及消防设备技术领域，且公开了一种消防闭门器应急备用装置，包括外壳、轴承、第一齿轮，所述外壳的顶部中心区域轴承贯穿卡接，所述第一齿轮固定安装在轴承顶端，所述轴承从顶端到底端依次固定套接有绳索盘、第二齿轮、电阻盘，所述轴承的右侧固定于外壳的内腔顶部有固定架，固定架的底端固定安装有滑轮，外壳的内腔底部固定安装有电磁装置，所述绳索盘固定连接有绳子，所述绳子通过滑轮转向后末端固定连接有永磁铁。该备用消防液压器是在液压装置失去功能后能使消防门正常使用的备用装置，同时独有的电磁吸附配合摩擦块Ⅰ和摩擦块Ⅱ对绳子的压力使门打开时省力关闭时匀速关门，再火灾发生时具有强吸附力使门紧闭的功能。
