Description
Technical Field
[0001] The utility model belongs to the technical field of detection and warning, and in particular relates to a downslide detection and warning device for a lift brake. Background Art
[0002] The brakes used in elevators are commonly divided into three types: disc block brakes, short-stroke electromagnetic brakes and friction plate brakes. They are all normally closed brakes. Normally closed brakes mean that the brakes are always in a braking state when the machine is stopped. The brakes will only be released after the motor is started, allowing the elevator to start operating. Therefore, it is necessary to confirm the braking state of the brakes through a downward sliding detection warning device.
[0003] Based on the above, the inventors have found that the existing elevator brake downslide detection and warning device has the following deficiencies:
[0004] 1. The device is in sliding contact with the bottom of the lift box, which results in a large friction force when the device is folded and extended. It is not convenient to add rolling contact measures to the device to reduce the friction resistance of the device when it is folded and extended;
[0005] 2. The device is retracted and extended by an electric cylinder, which results in a slow retraction process that affects normal lifting and lowering. It is not convenient to install quick retraction measures on the device to quickly retract and extend the device. Utility Model Content

[0030] The specific usage and function of this embodiment are as follows:
[0031] In the present utility model, Figure 1When the device body 1 shown is in use, the fixed bearing plate 8 is fixed inside the elevator channel by bolts so that it is at the lower part of the elevator box stop position, the retracting and extending motor 9 is connected to the elevator motor control box, and the alarm button 7 is connected to the external alarm. When the elevator is braked by the brake, the elevator motor loses power and stops rotating, the synchronous brake is energized for braking, and the synchronous retracting and extending motor 9 is energized for forward rotation. The retracting and extending motor 9 drives the retracting and extending rotating rod 10 to rotate forward synchronously, so that the retracting and extending rotating rod 10 rotates and engages with the retracting and extending moving block 11 threadedly, so that the retracting and extending moving block 11 descends through the threaded engagement, and the retracting and extending moving block 11 drives the upper end of the retracting and extending linkage rod 12 to synchronously descend, so that the lower end of the retracting and extending linkage rod 12 flips to the left, and the upper end of the flip bearing tube 5 is pushed to flip to the left by the lower end of the retracting and extending linkage rod 12, and the lifting detection rod 2 is driven to flip to the left synchronously by the flip bearing tube 5. The state is as follows Figure 4 As shown, the sliding contact wheel 3 is placed under the elevator case. When the bottom of the elevator case contacts the sliding contact wheel 3, the lifting detection rod 2 is forced to move downward and compress the reset column spring 4. When the lifting detection rod 2 is unable to press the alarm button 7 when it has descended, it means that the elevator brake has passed the braking and sliding distance. When the lifting detection rod 2 is able to press the alarm button 7 when it has descended, it means that the elevator brake has failed the braking and sliding distance. Thus, the elevator brake braking and sliding detection warning is realized. When the elevator descends again, the retracting and extending motor 9 is energized to reverse, and the retracting and extending rotating rod is driven by the retracting and extending motor 9. 10 is synchronously reversed, so that the retracting and unfolding rotating rod 10 rotates and engages with the retracting and unfolding moving block 11 threadedly, so that the retracting and unfolding moving block 11 rises through the threaded engagement, and the upper end of the retracting and unfolding linkage rod 12 is synchronously raised through the retracting and unfolding moving block 11, so that the lower end of the retracting and unfolding linkage rod 12 is flipped to the right, and the upper end of the flip bearing cylinder 5 is driven to flip to the right through the lower end of the retracting and unfolding linkage rod 12, and the lifting detection rod 2 is synchronously flipped to the right through the flip bearing cylinder 5, so that the lowering contact wheel 3 rolls to the right at the bottom of the elevator box, so that the lowering contact wheel 3 rolls to the right and leaves the bottom of the elevator box, and then the lifting detection rod 2 is raised and reset through the force of the reset column spring 4, and the state is as follows Figure 1 As shown, the lowering contact wheel 3 is retracted away from the bottom of the elevator box, the synchronous brake loses power and stops braking, and the synchronous elevator motor is powered on to rotate.
[0032] Embodiment 2:
[0033] The difference from the first embodiment is that the regular hexagonal prism of the anti-slip anti-rotation column 6 can also be set as a regular heptagonal prism, so that the anti-slip anti-rotation column 6 can only be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and disassembling the anti-slip anti-rotation column 6.
[0034] Embodiment three:
[0035] The difference from the first embodiment is that the regular hexagonal ring plate of the alarm button 7 can also be set as a regular heptagonal ring plate, so that the alarm button 7 can only be rotated by a special tool that cooperates with the regular heptagonal ring plate, preventing non-staff from rotating and disassembling the alarm button 7.
