[0048] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0049] 1. In the monitoring and warning device applied to the escalator brake, for the monitoring operation of the escalator brake, the simulation is completed by using the escalator drive wheel and the escalator drive belt to simulate the brake when it is installed inside the escalator, ensuring that the monitoring operation is consistent with the actual installation and use conditions. At the same time, when the escalator is actually in use, the position of the gear set outside the drive shaft can be adjusted by moving the outer movable block and the side stop block driven by the reciprocating screw rod, so that the second transmission gear installed inside the gear set can be meshed and transmitted with different first transmission gears, and the rotation speed of the rotating shaft can be adjusted by changing the gear ratio. Among them, by changing the rotation speed, the state of the escalator when transporting different numbers of passengers can be simulated in real time (the escalator speed is relatively fast when the number of passengers is small, and the escalator speed is relatively slow when the number of passengers is large), and the braking capabilities in different situations are monitored and recorded to ensure the safety of the brake when it is installed inside the escalator;

[0050] 2. In the monitoring and warning device applied to the escalator brake, when adjusting the rotation speed of the rotating shaft to simulate the state of the escalator under different use conditions, it only needs to drive the output end telescopic block, the outer ring body movably connected to the bottom of the telescopic block and the connecting rod to extend into the mating port inside the coupling shaft by the telescopic cylinder, which is simple and convenient to operate and effectively improves the efficiency of the escalator when it is used and monitored under different conditions. At the same time, for the connection methods of the connecting rod to the outer shaft rod and the coupling shaft respectively, it is ensured that the connection state of the two will not conflict when the connecting rod rotates and telescopic moves inside the two, and the connection can be cut off in time after the rotation speed adjustment, which is convenient for monitoring and recording the braking function of the brake;

[0051] 3. In the monitoring and warning device applied to the escalator brake, when monitoring the function of the brake, the monitored data can be transmitted to the inside of the electrical cabinet through the brake monitoring device, and the data recording and storage are realized through the brake control module inside the electrical cabinet. At the same time, when the braking effect reaches the critical point, the brake control module will transmit a signal to the brake monitoring device, release the operation of the brake through the brake monitoring device, and start the alarm to give an alarm warning, reminding the staff to record the data and restore the brake to its initial state, improving the safety of the monitoring operation;

[0052] 4. In the monitoring and warning device applied to the brake of an escalator, when the rotating shaft rotates and the rotation speed is adjusted, the driving of the rotational force and the change of the rotational speed are both completed through the meshing connection of several second speed-changing gears and several first speed-changing gears inside the gear set. At this time, through the design of gear meshing connection, not only can the rotational speed of the rotating shaft be adjusted by changing the transmission ratio of the meshing gears, but also the stability of the torque force (rotation) during transmission can be improved through the design of gear meshing connection, and it has a long service life when monitoring several escalator brakes.

There are two groups of escalator driving wheels 301. One group of escalator driving wheels 301 is installed on the side of the belt transmission assembly 80 by screws, and the other group of escalator driving wheels 301 is installed on the side of the brake clamping assembly 90 by screws. An escalator driving belt 302 is arranged outside the two groups of escalator driving wheels 301, and the escalator driving belt 302 is arranged obliquely.

[0079] In the monitoring and warning device for the brake of an escalator applied in the present invention, when monitoring the brake, the escalator driving wheel 301 and the escalator driving belt 302 can simulate the state when the brake is actually installed inside the escalator and in use, improving the accuracy of the brake during monitoring.

[0082] Specific reference Figure 5 、 Figure 6 and Figure 7, the gear shifting assembly 60 includes a driving shaft 601, the driving shaft 601 is connected to the output end of the motor 50 and is rotatably connected inside the positioning protrusion 602.

Among them, an activity cavity 6021 is provided inside the equipment table 10 between the two groups of positioning protrusions 602; a gear set 603, the gear set 603 is arranged outside the driving shaft 601, and a first speed-changing gear 604 is meshed at the bottom. A rotating shaft 605 is installed inside the first speed-changing gear 604, and the rotating shaft 605 is rotatably connected inside the activity cavity 6021; a protrusion 606, the protrusion 606 is installed outside the driving shaft 601 and is located between the two groups of positioning protrusions 602, and the protrusion 606 is slidably connected to the gear set 603.

[0083] In this embodiment, the gear set 603 is composed of three second speed-changing gears 6031, and the gear ratios of the three second speed-changing gears 6031 are 1:3:2. And there are three first speed-changing gears 604, which are respectively meshed with the three second speed-changing gears 6031. The rotation speed can be adjusted by the meshing connection between the second speed-changing gears 6031 and the first speed-changing gears 604 inside the gear set 603, simulating different states of the escalator during actual use.

[0084] At the same time, in this embodiment, a speed-changing switching assembly 70 is installed at the bottom of the driving shaft 601. The speed-changing switching assembly 70 is installed outside the second speed-changing gear 6031 at the central part, and drives the gear set 603 to move outside the driving shaft 601. And a belt transmission assembly 80 is installed at the bottom of the rotating shaft 605. The rotation of the rotating shaft 605 can drive the belt transmission assembly 80 to operate.

[0085] In the monitoring and warning device for the escalator brake applied in the present invention, when driving the belt transmission assembly 80 to operate, the driving shaft 601 is started to rotate through the internal control module of the electrical cabinet 40, driving the gear set 603 installed outside the driving shaft 601 to rotate, and causing the first speed-changing gear 604 meshed at the bottom of the gear set 603 to rotate. At this time, when the first speed-changing gear 604 rotates, it will drive the rotating shaft 605 installed inside it to rotate, so that the belt transmission assembly 80 connected to the outside of the rotating shaft 605 rotates and operates.

[0086] For specific reference Figure 8 、 Figure 9 and Figure 10, the speed change switching component 70 includes an extension shaft 701. The extension shaft 701 is installed at the bottom of the drive shaft 601 and is rotatably connected to the inside of the outer bracket 702. The outer bracket 702 is installed on the side of the positioning protrusion 602; a first transmission belt 703. The first transmission belt 703 is connected to the outside of the extension shaft 701 through a synchronous pulley and is movably connected to the side of the outer bracket 702. The inside of the first transmission belt 703 is also connected to a coupling shaft 704 through a synchronous pulley. Among them, a mating port 7041 is provided inside the coupling shaft 704; an outer frame 705. The outer frame 705 is installed on the top of the equipment table 10. A horizontal groove 706 is provided at the center of the top of the outer frame 705. An activity block 707 is slidably connected inside the horizontal groove 706; and a reciprocating lead screw 708. The reciprocating lead screw 708 is connected to the inside of the activity block 707 through a ball and is rotatably connected to the inside of the horizontal groove 706. A side stop block 7071 is provided at the bottom of the activity block 707. The side stop block 7071 is provided on the outside of the second speed change gear 6031 at the central part. Among them, a torque connection component 709 is provided on one side of the reciprocating lead screw 708 close to the coupling shaft 704. The torque connection component 709 extends into the mating port 7041.

[0087] In this embodiment, the torque connection component 709 includes an outer shaft rod 7091. The outer shaft rod 7091 is installed on the side of the reciprocating lead screw 708. A connecting rod 7092 extending to the outside is slidably connected inside the outer shaft rod 7091. The top of the connecting rod 7092 protrudes outward and forms a limiting part 7093. The limiting part 7093 is slidably connected to the outer shaft rod 7091. Among them, the connecting rod 7092 extends into the mating port 7041 through the limiting part 7093 and matches the mating port 7041; an outer ring body 7094. The outer ring body 7094 is installed on the outside of the connecting rod 7092. A telescopic block 7095 is movably connected to the top of the outer ring body 7094. The telescopic block 7095 is connected to the output end of a telescopic cylinder 7096. Among them, the telescopic cylinder 7096 is installed at the center of the top of the outer frame 705 and is located on the side of the horizontal groove 706.

[0088] In this solution, when it is necessary to adjust the rotation speed of the rotating shaft 605, the control module starts the telescopic cylinder 7096 to operate, moves the telescopic block 7095 connected to the output end of the telescopic cylinder 7096, and drives the outer ring body 7094 and the connecting rod 7092 movably connected to the bottom of the telescopic block 7095 to extend into the mating port 7041. When the coupling shaft 704 rotates, it drives the outer shaft rod 7091 to rotate and drives the reciprocating lead screw 708 connected to the outer shaft rod 7091 to rotate. When the coupling shaft 704 rotates, it drives the connecting rod 7092 and the outer shaft rod 7091 to rotate under the action of the limiting part 7093. Then, when it is necessary to release the connection state, the telescopic cylinder 7096 contracts to drive the telescopic block 7095, the outer ring body 7094 and the connecting rod 7092 to move, and moves the connecting rod 7092 out of the mating port 7041.

[0089] In the monitoring and warning device applied to the escalator brake of the present invention, when it is necessary to adjust the rotation speed of the rotating shaft 605, the rotation of the drive shaft 601 drives the extension shaft 701 installed at its bottom to rotate, and drives the first transmission belt 703 connected by a synchronous pulley on the outside of the extension shaft 701 to operate. At this time, when the first transmission belt 703 operates, it drives the coupling shaft 704 connected by a synchronous pulley on its inner side to rotate, so that the reciprocating lead screw 708 connected to the side of the coupling shaft 704 through the connecting rod 7092 and the outer shaft rod 7091 rotates. Then, when the reciprocating lead screw 708 rotates, the movable block 707 connected to its outside through a ball expands and contracts inside the horizontal groove 706, and drives the gear set 603 contacted by the bottom of the movable block 707 through the side stop block 7071 (outside the drive shaft 601 and does not affect normal rotation) to move, driving the second speed-changing gear 6031 inside the gear set 603 to move to the side of another first speed-changing gear 604 and meshing with the first speed-changing gear 604, and changing the rotation speed of the rotating shaft 605 through the change of the gear ratio.

[0091] In the monitoring and warning device applied to the escalator brake of the present invention, when the rotating shaft 605 rotates, it drives the second transmission belt 801 connected by a synchronous pulley on its outer side to operate, and drives the transmission shaft 802 connected by a synchronous pulley on the inner side of the second transmission belt 801 to rotate. At this time, when the transmission shaft 802 rotates, the turntable 804 installed on its outer side will rotate synchronously, and then drive the escalator transmission wheel 301 connected by screws on the side of the turntable 804 to rotate. At the same time, when the escalator transmission wheel 301 rotates, the escalator transmission belt 302 installed on its outer side will move, so that the brake braking assembly 90 connected by another group of escalator transmission belts 302 on the inner side of the escalator transmission belt 302 operates. At the same time, by driving the escalator transmission wheel 301 and the escalator transmission belt 302 to operate, the state when the brake is installed inside the escalator and used is simulated, so as to ensure that the monitoring results conform to the actual installation and use situation.

The brake braking monitoring device 903 is electrically connected to the electrical cabinet 40.

[0093] In the monitoring and warning device applied to the escalator brake of the present invention, when the escalator transmission wheel 301 rotates, the monitoring shaft 902 installed at its bottom will rotate, and the braking effect is monitored through the rotation of the monitoring shaft 902 and the brake installed on the outer side of the monitoring shaft 902. Among them, the brake is actually installed on the outer side of the brake braking monitoring device 903, and the brake braking monitoring device 903 records the driving braking ability and effect of the brake in real time and transmits it to the inside of the electrical cabinet 40 for feedback; the design of the brake braking monitoring device 903 can release the operation of the brake.

[0094] In the present invention, when performing brake detection, it is divided into three steps:

[0095] 1) Start: The escalator simulation assembly 30 operates to simulate the state of the escalator transmission belt 302 when the escalator operates. Then the gear speed change assembly 60, the speed change switching assembly 70, and the belt transmission assembly 80 operate to check the situation of the brake braking assembly 90 at different speeds;

[0096] 2) Reversal: After each forward rotation detection is completed, the escalator simulation component 30 is used to detect the reverse rotation of the brake braking component 90, improving the stability and accuracy of the brake braking component 90 during detection;

[0097] 3) Reset: After the detection is completed, the internal parts of the brake detection device return to their original positions.
