In this embodiment, the movable pressing block structure 210 can be driven to move by manual driving. Manual force is applied to the driving handle 223 to drive the driving pawl 222 and further to move the ratchet wheel 221, and finally to move the movable pressing block structure 210. So set up, elevator flaring device 1000 structure is more simple, convenient to carry for detect operation convenient and fast more.
Because the flaring device 1000 of the elevator needs to extend into the gap between the coil end cover 421 and the brake arm 422 of the elevator brake 420, the detection operation is further simplified and is more convenient for holding. The base assembly 100 may further include a support handle 120 disposed alongside the drive handle 223, the support handle 120 being configured to support the base assembly 100. On the one hand, support handle 120 makes base assembly 100 support more stable, and on the other hand, support handle 120 is also convenient for hold, and the inspector both hands hold support handle 120 and actuating handle 223 respectively, simplify detection operation, promote detection efficiency.

To ensure smooth power transmission, the movement of the rack 213 is not deviated from the designed direction, and the power is smoothly transmitted to the movable pressing block structure 210. A guide block 140 may be disposed on the base assembly 100, the guide block 140 is pressed on the upper panel 160 and the lower panel 170 of the base assembly 100, the position of the guide block 140 is disposed corresponding to the ratchet wheel 221, and the guide block 140 is used for pressing against the ratchet wheel 221 and the rack 213 to transmit a lateral force generated when the force is transmitted, and guiding the rack.
Referring to fig. 1, in a preferred embodiment of the present invention, the operation procedure for detecting the working condition of the lever drum brake by using the flaring device 1000 of the elevator is as follows: when the driving handle 223 swings clockwise and leftward, the ratchet wheel 221 is driven by the driving pawl 222 to rotate clockwise, so as to drive the rack 213 to move rightward, and the pressing block 211 fixed on the rack 213 opens rightward. Because the weight of the elevator counterweight side is greatly different from that of the elevator car side, when a brake shoe of the brake is separated from a brake drum, the elevator is kept still, otherwise, the brake on the other side is indicated to be problematic, if the situation occurs, the driving handle 223 can be immediately swung to the right to the bottom, so that the non-return pawl 224 is released, and under the action of the brake pressing spring, the movable pressing block structure 210 drives the rack 213 to move to the left, so that the brake on the side is put into operation, and the moving elevator is stopped.
In the drum brakes of elevators that are commonly used at present, the adjustment of the pressure value of the compression spring is very critical. The magnitude of the spring pressure can be adjusted through the compression nut, and the excessive or insufficient pressure of the compression spring can generate adverse effect on the braking of the elevator. When the spring pressure is too large, the electromagnetic force generated by the coil of the brake can not overcome the spring pressure and can not be completely and normally opened, so that the elevator dragging brake can operate; the spring pressure is too low to provide sufficient braking torque, which may prevent the elevator from braking properly. In both cases, elevator accidents may occur. Therefore, it is very necessary to measure the pressure of the lever drum brake hold-down spring to verify whether the spring pressure is within the range specified by the manufacturer when the elevator is regularly maintained and inspected.
