Description

Technical Field

[0001] The utility model belongs to the technical field of elevator brake assembly equipment, in particular to an elevator brake assembly detection device. Background Art

[0002] The elevator brake is an important safety device for elevators. Its safety and reliability are one of the important factors to ensure the safe operation of elevators. The bidirectional thrust elevator brake generates bidirectional electromagnetic thrust when powered on, which causes the brake mechanism to be separated from the rotating part of the motor (i.e. released). When the power is off, the electromagnetic force disappears, and under the action of the external brake spring pressure, a friction brake is formed for power-off braking. When installing the armature assembly of the elevator brake, hydraulic equipment needs to be used for pressing.

[0003] When a conventional hydraulic press is used directly for pressing, the elevator brake is prone to over-squeezing, which can easily cause pressure damage. If the elevator brake is not placed properly, it is easy to be damaged by uneven force, resulting in the problem of low practicality of conventional hydraulic equipment for assembling elevator brakes.

[0004] Therefore, we propose an elevator brake assembly detection device to solve the above problems. Utility Model Content

After placing the initially installed brake on the target bracket, push the bracket into the hydraulic press, guide the target bracket inward by using the positioning plate, sense the position by the sensor, unlock the hydraulic press downward drive control authority when the sensor senses in place, avoid the hydraulic press from running idle, use the brake to limit the hydraulic press's descending range, and improve the safety factor; when driving the hydraulic press downward, use the pressure sensor to detect the pressure, and use the extrusion frame to press the brake to improve practicality.

[0008] Preferably, the lock buckle comprises a lock frame, a first bolt, a pressure bolt and an extrusion block, wherein the pressure bolt is threadedly mounted on the upper portion of the lock frame, the lower end of the first bolt contacts the extrusion block, the pressure bolt is symmetrically slidably mounted on the inner end of the lock frame, and the extrusion block is movably clamped between the pressure bolts. The first bolt is screwed upward to loosen the extrusion block, which in turn loosens the pressure bolt, thereby loosening the guide column of the hydraulic press, and then the height of the lock buckle is adjusted, and then the first bolt is tightened to allow the pressure bolt to re-press and fix the guide column of the hydraulic press, thereby facilitating the adjustment of the height of the lock buckle.

[0009] Preferably, the lock buckle further comprises a knob, which is fixedly connected to the upper end of the first bolt. The knob is used to increase the length of the screwing lever of the first bolt, so as to facilitate manual operation of rotating the first bolt.

[0010] Preferably, the lock buckle further comprises a threaded ring, the threaded ring is fixedly connected to the upper end of the lock frame, and the first bolt is threadedly installed on the inner end of the threaded ring. The threaded ring is used to increase the thread installation range of the first bolt and improve the stability of the first bolt.

[0011] Preferably, a groove is formed at the outer end of the pressure bolt, so as to increase the contact range between the pressure bolt and the guide column of the hydraulic press.

[0012] Preferably, the brake comprises a brake switch, a level sensor and a fixing frame, the lower end of the brake switch is fixedly connected to the fixing frame, and the level sensor is fixedly connected to the upper part of the fixing frame. When the pressure plate of the hydraulic press squeezes the brake switch, the downward driving command of the hydraulic press is shut down through the brake switch; the levelness of the brake switch is detected by the level sensor, so as to conveniently ensure the levelness of the brake switch.

[0013] Preferably, the positioning plate comprises a plate body, a guide bar and a second bolt, wherein the plate body and the guide bar are fixedly connected as one body. The second bolt passes through the guide bar and is tightened and fixed to the lower part of the hydraulic press.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. After placing the initially installed brake on the target bracket, push the bracket into the hydraulic press, use the positioning plate to guide the target bracket inward, and use the sensor to sense the position. When the sensor senses the position, unlock the hydraulic press downward drive control authority to avoid the hydraulic press from running idle. Use the brake to limit the hydraulic press's descent range and improve the safety factor. When driving the hydraulic press downward, use the pressure sensor to detect the pressure and use the extrusion frame to press the brake to improve practicality.

[0016] 2. Twist the first bolt upward to loosen the extrusion block, which in turn loosens the pressure bolt, thereby loosening the guide column of the hydraulic press. Then adjust the height of the lock, and tighten the first bolt again to tighten the pressure bolt and fix the guide column of the hydraulic press, making it easier to adjust the height of the lock.

[0017] 3. When the pressure plate of the hydraulic press squeezes the brake switch, the downward drive command of the hydraulic press is shut down through the brake switch; the horizontality of the brake switch is detected by the level sensor to ensure the horizontality of the brake switch.
