[0001] This utility model relates to the field of emergency brake technology, specifically a multi-functional unit fixed lifting and releasing emergency brake device. Background Technology

[0002] The aluminum electrolysis multi-functional unit, also known as the aluminum electrolysis overhead crane, can meet the working environment of high lava flow, high current, and strong magnetic field in the electrolysis cell of the aluminum electrolysis workshop. It is a key piece of equipment in the large-scale prebaked anode aluminum electrolysis production process. In aluminum electrolysis, the multi-functional unit is used to lift the busbar or the upper part of the cell for hoisting operations. When the motor of the multi-functional unit's fixed crane fails, an emergency brake device is used to achieve emergency braking.

[0003] In the existing technology, when installing the brake chuck, since the mounting bracket is fixed, if the angle and position of the chuck deviate, it is impossible to adjust the brake angle and position of the chuck. Therefore, it is necessary to disassemble and reassemble the mounting bracket to adjust the brake angle and position of the chuck. This not only has poor applicability, but also makes the operation more troublesome. Furthermore, it is impossible to monitor the brake in real time after it is engaged. Once the brake becomes loose, it cannot be detected in time, which poses a safety hazard. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: it includes a mounting frame 1 and a chuck 14, the chuck 14 being disposed above the mounting frame 1. A guide rail 2 is fixed inside the mounting frame 1, and a guide block 3 is slidably sleeved around the guide rail 2. A first lead screw 4 is rotatably connected inside the mounting frame 1, and the guide block 3 is threadedly sleeved with the first lead screw 4. A first anti-rotation operating component is provided on the left side of the mounting frame 1. The first anti-rotation operating component includes a first anti-slip pad 5, a first operating plate 6, a first locking tooth block 7, a first return spring 8, a first pull rod 9, and a first operating lever 10. The first anti-slip pad 5 is fixed to the mounting frame 1. On the left side, the first lead screw 4 rotates through the mounting bracket 1 and the left side of the first anti-slip pad 5. The first operating plate 6 is fixed to the left end of the first lead screw 4. There are two first locking blocks 7, both of which abut against the left side of the first anti-slip pad 5. There are two first return springs 8, which are connected to the left side of the two first locking blocks 7. The right side of the first operating plate 6 is connected to the left end of the first return spring 8. There are two first pull rods 9, which are fixed to the left side of the two first locking blocks 7. The first pull rods 9 slide through the first operating plate 6. The first operating lever 10 is fixed to the left end of the two first pull rods 9.

[0023] When adjusting the left and right brake positions of the chuck 14, hold the first operating lever 10 and pull the first pull rod 9 and the first locking block 7 to the left. The first locking block 7 will compress the first return spring 8, so that the first locking block 7 does not contact the first anti-slip pad 5. Then rotate the first operating plate 6 and the first lead screw 4. The first lead screw 4 will drive the guide block 3 to slide left and right along the guide rail 2, thereby driving the hydraulic cylinder 11, the concave frame 12, the adjusting plate 13 and the chuck 14 to move left and right together, which is convenient for adjusting the brake position of the chuck 14. It is easy to operate and has good applicability.

[0024] After the chuck 14 position is adjusted, release the first operating lever 10 and stop compressing the first return spring 8. At this time, the rebound force of the first return spring 8 will drive the first operating lever 10, the first pull rod 9 and the first locking block 7 to reset, so that the first locking block 7 abuts against the first anti-slip pad 5. Since the first locking block 7 abuts against the first anti-slip pad 5, the friction is increased, which helps to prevent the first lead screw 4 from rotating accidentally, thereby ensuring the stability of the chuck 14 after the position is adjusted.

[0025] In this embodiment, a support frame 17 is fixed at the middle position of the bottom of the concave frame 12. A gear 18 is rotatably connected to the upper end of the support frame 17. An adjusting block 19 is fixed between the gear 18 and the adjusting plate 13. A slider 20 is slidably connected to the bottom of the concave frame 12. A toothed plate 21 is fixed to the upper end of the slider 20. The toothed plate 21 meshes with the gear 18. A second lead screw 21 is rotatably connected inside the concave frame 12. The slider 20 is threadedly connected to the second lead screw 21. A second anti-rotation operating component is provided on the left side of the concave frame 12. The second anti-rotation operating component includes a second anti-slip pad 24, a second operating plate 23, a second locking block 25, a second return spring 26, a second pull rod 27, and a second... The operating lever 28, the second anti-slip pad 24 is fixed to the left side of the concave frame 12, the second lead screw 22 rotates through the concave frame 12 and the left side of the second anti-slip pad 24, the second operating plate 23 is fixed to the left end of the second lead screw 22, there are two second locking blocks 25, both abutting the left side of the second anti-slip pad 24, there are two second return springs 26, each fixed to the left side of the two second locking blocks 25, the right side of the second operating plate 23 is connected to the left end of the second return spring 26, there are two second pull rods 27, each fixed to the left side of the two second locking blocks 25, and the second pull rods 27 slide through the left side of the second operating plate 23, the second operating lever 28 is fixed to the left end of the two second pull rods 27.

[0026] When adjusting the brake angle of the chuck 14, hold the second operating lever 28 and pull the second pull rod 27 and the second locking block 25 to the left. The second locking block 25 will compress the second return spring 26, so that the second locking block 25 does not contact the second anti-slip pad 24. Then rotate the second operating plate 23 and the second lead screw 22. The second lead screw 22 will drive the convex tooth plate 21 to slide left and right along the concave frame 12. At the same time, the convex tooth plate 21 will drive the gear 18 to rotate forward or backward. Therefore, the gear 18 will drive the adjusting block 19, the adjusting plate 13 and the chuck 14 to tilt together, which is convenient for adjusting the brake angle of the chuck 14. It is easy to operate and has good applicability.

[0027] After the chuck 14 angle is adjusted, release the second operating lever 28 and stop compressing the second return spring 26. At this time, the rebound force of the second return spring 26 will drive the second operating lever 28, the second pull rod 27 and the second locking block 25 to reset, so that the second locking block 25 abuts against the second anti-slip pad 24. Since the second locking block 25 abuts against the second anti-slip pad 24, the friction is increased, which helps to prevent the second lead screw 22 from rotating accidentally, thus ensuring the stability of the chuck 14 after the angle is adjusted. In summary, there is no need to disassemble and assemble the mounting bracket 1 again to adjust the brake angle and position of the chuck 14, which helps to reduce disassembly and assembly troubles and has good applicability.

[0028] In this embodiment, a hydraulic cylinder 11 is fixed to the upper end of the guide block 3, a concave frame 12 is fixed to the power end of the hydraulic cylinder 11, an adjustment plate 13 is provided above the concave frame 12, a chuck 14 is located above the adjustment plate 13, and a pressure sensor 15 and a telescopic rod 16 are connected between the chuck 14 and the adjustment plate 13. An alarm 29 is fixed to the front of the mounting frame 1, and the pressure sensor 15 is signal connected to the alarm 29.

[0029] When the hydraulic cylinder 11 extends and drives the chuck 14 to brake the motor shaft, a pressure sensor 15 and an alarm 29 are installed. When the pressure sensor 15 is pressed, the pressure sensor 15 monitors the pressure value normally. Once the pressure sensor 15 detects an abnormality and the pressure value decreases, it indicates that the chuck 14 is loosening its grip on the motor shaft. The pressure sensor 15 will then control the alarm 29 to sound an alarm. This allows the staff to promptly detect the loosening of the brake and carry out maintenance, reducing safety hazards.

[0030] Working principle:

[0031] When adjusting the left and right brake positions of the chuck 14, hold the first operating lever 10 and pull the first pull rod 9 and the first locking block 7 to the left. The first locking block 7 will compress the first return spring 8, thus preventing the first locking block 7 from contacting the first anti-slip pad 5. Then, rotate the first operating plate 6 and the first lead screw 4. The first lead screw 4 will drive the guide block 3 to slide left and right along the guide rail 2, thereby driving the hydraulic cylinder 11, the concave frame 12, the adjusting plate 13, and the chuck 14 to move left and right together, facilitating the adjustment of the brake position of the chuck 14. After the position of the chuck 14 is adjusted, release the first operating lever 10. When the lever 10 stops compressing the first return spring 8, the rebound force of the first return spring 8 will cause the first operating lever 10, the first pull rod 9, and the first locking block 7 to reset, thereby causing the first locking block 7 to abut against the first anti-slip pad 5. The friction increased by the first locking block 7 against the first anti-slip pad 5 helps prevent the first lead screw 4 from rotating accidentally. When adjusting the brake angle of the chuck 14, the second operating lever 28 is held and pulled to the left to move the second pull rod 27 and the second locking block 25. The second locking block 25 will compress the second return spring 26, thus preventing the second locking block 25 from engaging with the first anti-slip pad 5. The second anti-slip pad 24 contacts the contact point, and then the second operating plate 23 and the second lead screw 22 are rotated. The second lead screw 22 will drive the toothed plate 21 to slide left and right along the concave frame 12. At the same time, the toothed plate 21 will drive the gear 18 to rotate forward or backward. Therefore, the gear 18 will drive the adjusting block 19, the adjusting plate 13 and the chuck 14 to tilt together, which is convenient for adjusting the brake angle of the chuck 14. After the angle of the chuck 14 is adjusted, the second operating lever 28 is released and the second return spring 26 is no longer compressed. At this time, the rebound force of the second return spring 26 will drive the second operating lever 28 to rotate. The second pull rod 27 and the second locking block 25 are reset, thereby causing the second locking block 25 to abut against the second anti-slip pad 24. Since the second locking block 25 abuts against the second anti-slip pad 24, the friction is increased, which helps to prevent the second lead screw 22 from rotating accidentally. When the extension of the hydraulic cylinder 11 drives the chuck 14 to brake the motor shaft, the pressure sensor 15 is pressed. The pressure sensor 15 monitors the pressure value normally. Once the pressure sensor 15 shows abnormal monitoring and decreases, it indicates that the chuck 14 has loosened its brake on the motor shaft. The pressure sensor 15 will control the alarm 29 to sound an alarm.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
