Abstract

This invention presents a brake control device for high-rise fire rescue systems, notable for its well-thought-out design, high safety standards, and consistent, dependable functionality. The system features two main elements: cable take-up device A on base frame A, and cable take-up device B on base frame B. A connecting device ensures the A transfer spindle of device A and the B transfer spindle of device B rotate in unison. Central to the system is the emergency braking device, comprising a reduction gearbox located under either the A or B cable take-up device. This gearbox is equipped with an input shaft and an output shaft, linked by a gear transmission set. The input shaft connects to the A or B cable take-up device via a transmission member. A magnetic block is affixed to the output shaft's end, and a permanent magnetic crane is positioned at the magnetic block's end.

A braking control device for a high-rise fire rescue system, the high-rise fire rescue system comprising:

an A cable take-up device (2) mounted on a base frame A (1) and a B cable take-up device (4) mounted on a base frame B (3), an A transfer spindle (5) on the A cable take-up device (2) and a B transfer spindle (6) of the B cable take-up device (4) being connected together by a connection device (7) to achieve synchronous rotation;
wherein the braking control device comprises a reduction gearbox (8) located below the A cable take-up device (2) or the B cable take-up device (4), wherein the reduction gearbox (8) comprises an input shaft (9) and an output shaft (10) and a gear train, the input shaft (9) and the output shaft (10) is connected by the gear train, the input shaft (9) is connected to the A cable take-up device (2) or a drive member (11) is provided between the input shaft (9) and the B cable take-up device (4), a magnetic block (12) is provided at one end of the output shaft (10), and a permanent magnetic crane (13) is provided at one end of the magnetic block (12);
wherein a mounting base (17) is provided at a lower end of the reduction gear box (8), a side plate (18) is provided at each end of the mounting base (17), a connecting horizontal plate (19) is provided at an upper end of one side plates (18), and a connecting longitudinal plate (20) is provided at one end of the connecting horizontal plate (19);
a connecting square tube (21) is provided between the connecting horizontal plate (19) and the mounting base (17), a central part of the connecting square tube (21) is provided with a mounting slot (22), the mounting slot (22) is fitted with the permanent magnetic crane (13), one end of the permanent magnetic crane (13) is provided with at least two nuts (23), the connecting longitudinal plate (20) is provided with at least two adjusting bolts (24), the adjusting bolts (24) are connected to the nuts (23) through the connecting longitudinal plate (20) and the mounting slot (22), one end of the output shaft (10) passes through the one side plate (18) and is located at an other end of the permanent magnetic crane (13), and an other end of the output shaft (10) passes through an other side plate (18).
