Description

Technical Field

[0001] The present invention belongs to the field of elevator brake detection, and in particular, relates to an elevator brake safety performance 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 disengages the brake mechanism from the rotating part of the motor. 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. It is mainly matched with the drive motor on the elevator traction machine to form an electromagnetic brake three-phase asynchronous motor for elevators. It is widely used in occasions that can achieve smooth parking and rapid starting, as well as safe braking when the power is off; and the elevator brake safety performance detection device is a device specifically used to monitor and evaluate the safety performance of elevator brakes. The device uses a series of technical means to detect the operating status of the elevator brake in real time to ensure that it meets safety standards, thereby ensuring the safe operation of the elevator.

[0003] After searching, Chinese patent number CN220602790U discloses an elevator brake detection device, which relates to the field of elevator brake detection technology, including a fixed plate, a fixed frame is fixed on the upper surface of the fixed plate, a top plate is fixed on the upper end of the fixed frame, a traction machine is fixed on the upper surface of the top plate, a brake is fixed on the traction machine, a wire rope is wound on the traction machine, a simulation box is fixed on one end of the wire rope, a load-bearing plate is fixed on the other end of the wire rope, a fixed column is fixed on the upper surface of the top plate, a lifting rod is slidably provided on the fixed column, and a fixed plate is fixed on the upper end of the lifting rod.

[0031] The working principle of the elevator brake safety performance detection device proposed by the present invention is that the traction machine 5 drives the wire rope 7 to move, the wire rope 7 drives the load-bearing plate 9 to rise, and the other end drives the simulation box 8 to descend. When the simulation box 8 descends to a certain position, the traction machine 5 is stopped by the brake 6. At this time, the lower end of the simulation box 8 is in contact with the detection mechanism. At this time, the detection mechanism can be used to buffer the simulation box 8 to prevent the simulation box 8 from being damaged due to excessive descent speed. At the same time, the brake 6 can also be tested for safety performance.

[0032] It is worth noting that the brake 6 can be quickly disassembled and installed through the fixing mechanism, so that different brakes 6 can be easily tested.

[0033] In one embodiment, for the above-mentioned support rod 2, the support rod 2 is fixedly installed above the bottom plate 1, the top plate 3 is fixedly installed on the top of the support rod 2, the sliding groove 4 is fixedly installed above the bottom plate 1, and the traction machine 5 is fixedly installed above the top plate 3.

[0034] In one embodiment, for the above-mentioned fixing mechanism, the fixing mechanism includes a clamping block 10 arranged on the brake 6, the clamping block 10 is fixedly installed on the brake 6, the hoisting machine 5 is provided with a clamping hole 11, the clamping hole 11 is slidably connected with the clamping block 10, the clamping block 10 is provided with a hole 12, the hole 12 is clamped with a bolt 13, and the bolt 13 is threadedly connected to the traction machine 5.

[0035] The working principle of the elevator brake safety performance detection device proposed by the present invention is that when the brake 6 needs to be disassembled, the operator can rotate the bolt 13 so that the bolt 13 is disengaged from the clamping hole 11, and then the brake 6 can be pulled, so that the clamping block 10 is disengaged from the inside of the clamping hole 11, thereby facilitating the disassembly of the brake 6;

[0036] When the brake 6 needs to be installed, it is only necessary to snap the block 10 into the inside of the snap hole 11 and then rotate the bolt 13 so that the bolt 13 can be snapped into the inside of the hole 12 to complete the installation of the brake 6.

[0037] In one embodiment, for the above-mentioned wire rope 7, one end of the wire rope 7 passes through the top plate 3 and is fixedly connected to the simulation box 8, and the other end is fixedly connected to the load-bearing plate 9 through a fixed pulley 14, and the fixed pulley 14 is rotatably installed on the top plate 3, and the load-bearing plate 9 is fixedly installed with a sliding block 15, and the sliding block 15 is slidably connected to the inside of the sliding groove 4.

[0038] In one embodiment, for the above-mentioned detection mechanism, the detection mechanism includes a detection box 16 arranged above the base plate 1, one end of a buffer column 17 is fixedly installed inside the detection box 16, and a buffer plate 18 is fixedly installed on the other end of the buffer column 17. The buffer plate 18 is slidably connected to the inside of the detection box 16, and a detection table 19 is fixedly installed on the detection box 16, and a buffer spring 20 is sleeved on the buffer column 17.

[0039] In one embodiment, for the above-mentioned buffer plate 18, a protrusion block 21 is fixedly installed on one side of the buffer plate 18 close to the detection box 16, and the protrusion block 21 is rotatably installed with one end of a connecting rod 22, and the other end of the connecting rod 22 is rotatably installed on a sliding disk 23, and the sliding disk 23 is slidably connected to a fixed shaft 24, and the fixed shaft 24 is fixedly installed inside the detection box 16.

[0040] In one embodiment, for the protruding block 21 , two protruding blocks 21 , connecting rods 22 and sliding disks 23 are provided, and their installation methods are the same. A return spring 25 is provided between the two sliding disks 23 , and the return spring 25 is sleeved on the fixed shaft 24 .

[0041] In one embodiment, for the above-mentioned support rods 2 , four support rods 2 are provided, and the four support rods 2 are used to support the top plate 3 .

[0042] The working principle of the elevator brake safety performance detection device proposed by the present invention is that when the simulation box 8 falls on the buffer plate 18, the buffer column 17 and the buffer spring 20 cooperate with each other to play a preliminary shock absorbing role on the buffer plate 18, thereby buffering the simulation box 8 above to prevent collision and damage;

[0043] It is worth noting that the simulation box 8 will drive the buffer plate 18 to move, so that the buffer plate 18 moves toward the inside of the detection box 16, and then drives the protrusion block 21 to move, thereby driving one end of the connecting rod 22 to rotate, and the other end drives the sliding plate 23 to move along the fixed axis 24 while rotating. At this time, the two sliding plates 23 will move toward the center position of the fixed axis 24 at the same time, so that the reset spring 25 will shrink and maintain the outward tension force, and then use the reaction force of the reset spring 25 to drive the buffer plate 18 to move away from the detection box 16, so that the buffer plate 18 repeatedly moves up and down, so as to further buffer the simulation box 8 to prevent damage, and the descent distance is recorded on the detection table 19, which is convenient for intuitively understanding the braking torque of the elevator and convenient for personnel to adjust the braking torque of the elevator.
