[0002] A brake is a device that has functions such as decelerating, stopping, or maintaining a stopped state of a moving part (or moving machinery), and is a mechanical part that stops or decelerates a moving part in a machine. Commonly known as a brake or a brake, a brake mainly consists of a brake frame, a braking member, and a control device, etc. Some brakes are also equipped with an automatic adjustment device for the clearance of the braking member. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), it should be installed on the low-speed shaft close to the working part of the equipment. At present, some industrial brakes are mainly used as safety brakes in the crane industry, metallurgical industry, and mines. Industrial brakes are mainly divided into various types according to their structures: arm disc brakes, block brakes, caliper disc brakes, etc.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0044] Refer to Figures 1-5, A brake for an industrial device and a method for monitoring the brake state, including a connecting pipe 2 provided at one end of a motor 1 and a rotating rod 3 provided on the side of the connecting pipe 2; a housing 4 is connected to the surface of the connecting pipe 2, and a positioning component is provided on the surface of the housing 4; the internal of the positioning component includes a sleeve 12, and a through groove 13 is provided at the connection between the sleeve 12 and the housing 4; a moving groove 14 is provided on the surface of the sleeve 12, and an L-shaped rod 15 is movably connected inside the moving groove 14. A pressure sensor 16 is provided at the bottom end inside the sleeve 12, and a first spring 17 is connected to the top end of the pressure sensor 16. The top end of the first spring 17 is connected to a T-shaped rod 18, and a limiting ball 19 is connected to the top end of the T-shaped rod 18; a positioning hole 20 is provided on the surface of the connecting pipe 2; an auxiliary component is provided on the surface of the connecting pipe 2, and an extrusion component is provided inside the connecting pipe 2. The through groove 13 facilitates moving the T-shaped rod 18 and the limiting ball 19 into the inside of the housing 4. When in use, when the motor 1 is powered on, the electromagnet 25 is also powered on. After being powered on, the electromagnet 25 can attract the moving plate 22, so that the support rod 23 at the top end of the moving plate 22 drives the second extrusion ball 24 to move and move it to the surface of the first extrusion ball 10 to extrude it, so that the first extrusion ball 10 drives the cushion block 9 to move through the connecting rod 8, and moves the cushion block 9 into the limiting groove 6, so that when the connecting plate 5 rotates, the limiting ball 19 can move from the surface of the cushion block 9. When the motor 1 is powered off, the electromagnet 25 is also powered off. Through the action of the third spring 21, the moving plate 22 can drive the second extrusion ball 24 to move away from the first extrusion ball 10. At the same time, the first extrusion ball 10 drives the cushion block 9 and the like to move through the second spring 11, and the cushion block 9 can be moved into the connecting plate 5. Through the action of the first spring 17, the T-shaped rod 18 can drive the limiting ball 19 to move, and the limiting ball 19 can be moved into the limiting groove 6 to brake and limit the connecting pipe 2, the rotating rod 3, etc. At the same time, when the T-shaped rod 18 moves, it can drive the L-shaped rod 15 to move, and the L-shaped rod 15 can be moved into the positioning hole 20 to brake and limit the connecting pipe 2, the rotating rod 3, etc. again.

[0045] Further, the cross-section of the housing 4 is square, and sleeves 12 are provided on all four sides of the housing 4. The distances between the L-shaped rods 15 on the sleeves 12 on the surface of the square-section housing 4 and the positioning holes 20 are the same, so that it is convenient for each L-shaped rod 15 to contact the inside of the positioning hole 20 at the same time.

[0046] Further, the positioning holes 20 are annularly and equidistantly distributed on the surface of the connecting pipe 2. The number of L-shaped rods 15 is the same as the number of positioning holes 20, and the L-shaped rods 15 are in contact with the inside of the positioning holes 20, so as to brake and limit the connecting pipe 2.

[0047] Further, the L-shaped rod 15 passes through the moving groove 14 and is connected to the surface of the T-shaped rod 18. The moving groove 14 facilitates the T-shaped rod 18 to drive the L-shaped rod 15 to move when moving.

[0048] Further, the interior of the auxiliary component includes a connecting plate 5, and a limiting groove 6 is formed on the surface of the connecting plate 5. A vertical plate 7 is arranged inside the connecting plate 5, and a connecting rod 8 is slidably connected to the surface of the vertical plate 7. One end of the connecting rod 8 is connected to a cushion block 9, and the other end of the connecting rod 8 is connected to a first extrusion ball 10. A second spring 11 is arranged between the vertical plate 7 and the first extrusion ball 10. The second spring 11 facilitates the limiting movement of the cushion block 9 and the first extrusion ball 10 through the connecting rod 8.

[0049] Further, the limiting grooves 6 and the vertical plates 7 are annularly and equidistantly distributed on the surface of the connecting plate 5. The limiting grooves 6 correspond to the cushion blocks 9 one by one, and the number of the limiting grooves 6, the cushion blocks 9, and the limiting balls 19 is the same. The orientation of the positioning holes 20 is also the same as that of the limiting grooves 6, facilitating the L-shaped rod 15 to be in contact with the inside of the positioning holes 20 when the limiting balls 19 are in contact with the inside of the limiting grooves 6.

[0050] Further, the interior of the extrusion component includes a third spring 21, and the third spring 21 is located at the bottom end inside the connecting pipe 2. The top end of the third spring 21 is connected to a moving plate 22, and the top end of the moving plate 22 is connected to a support rod 23. The top end of the support rod 23 is connected to a second extrusion ball 24. An electromagnet 25 is installed on the inner wall of the connecting pipe 2. The electromagnet 25 is connected to a power supply and a control board. Whether the power supply supplies power to the electromagnet 25 is controlled by the control board. When the electromagnet 25 is powered on, it facilitates the second extrusion ball 24 to move towards the surface of the first extrusion ball 10. When the electromagnet 25 is powered off, under the action of the third spring 21, the second extrusion ball 24 moves away from the first extrusion ball 10. The pulling force of the third spring 21 is greater than the elastic force of the four second springs 11, so that when the electromagnet 25 is powered off, the third spring 21 can make the second extrusion ball 24 move.

[0051] Further, the moving plate 22 is slidably connected to the inner wall of the connecting pipe 2, and the moving plate 22 is a metal plate that can be attracted by the electromagnet 25 when the electromagnet 25 is powered on. When the electromagnet 25 is powered on, the moving plate 22 can drive the support rod 23 and the second extrusion ball 24 to move, and the second extrusion ball 24 can be moved to the surface of the first extrusion ball 10 and extruded. The first extrusion ball 10 can drive the connecting rod 8 and the cushion block 9 to move, and the cushion block 9 inside the connecting plate 5 can be moved into the limiting groove 6 to block the limiting groove 6, facilitating the limiting ball 19 to move from the surface of the limiting groove 6.

[0052] A method for monitoring the brake state of an industrial device, including a pressure sensor 16, which is used to monitor the pressure values received by the limit ball 19 and the T-shaped rod 18.

[0053] Further, it includes the following steps:

[0054] S1: When the motor 1 stops working, the electromagnet 25 is powered off. Through the action of the third spring 21, the moving plate 22, the support rod 23, the second extrusion ball 24, etc. can be pulled to move, and the second extrusion ball 24 can be moved away from the surface of the first extrusion ball 10.

[0055] S2: At the same time, through the action of the second spring 11, the first extrusion ball 10, the connecting rod 8, the cushion block 9, etc. can be driven to move into the inside of the connecting plate 5, and the cushion block 9 can be moved into the inside of the connecting plate 5, so that the limit groove 6 on the surface of the connecting plate 5 is exposed.

[0056] S3: And through the action of the first spring 17, the T-shaped rod 18 and the limit ball 19 can be pushed to move, and the limit ball 19 can be moved into the limit groove 6 to limit the connecting plate 5, the connecting pipe 2, the rotating rod 3, etc. At the same time, when the T-shaped rod 18 moves, the L-shaped rod 15 connected to its surface can be driven to move inside the moving groove 14, and one end of the L-shaped rod 15 can be moved into the positioning hole 20, so as to brake and limit the connecting pipe 2, etc. again.

[0057] S4. Finally, the pressure sensor 16 is used to monitor the pressure received by the T-shaped rod 18, the limit ball 19, etc. If the pressure is within the set threshold range, it means that the connecting pipe 2, the rotating rod 3, etc. are braked normally. If the pressure is less than or greater than the set threshold, it means that the connecting pipe 2, the rotating rod 3, etc. are braked abnormally, and a signal is output for an alarm.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
