Description

Technical Field

[0001] This invention relates to the field of elevator brake technology, specifically to a cleaning device for elevator brakes. Background Technology

[0002] Elevator brakes are important safety devices for elevators. Their safety and reliability are one of the key factors in ensuring the safe operation of elevators. They are characterized by their compact structure, convenient installation, low noise, and low vibration.

[0003] The existing elevator brakes lack cleaning and self-inspection mechanisms, making it impossible to clean the outer walls of the brake wheel and brake shoes, as well as the inner walls of the traction groove. This can easily lead to insufficient braking force of the brake and insufficient traction force of the traction wheel, further affecting the braking effect of the brake and the traction effect of the traction wheel. It also makes it easy for manual inspection to miss or mischeck the height difference of the wire rope, which can easily lead to safety hazards in the elevator.

[0004] To address the aforementioned problems, the inventors have proposed a cleaning device for elevator brakes. Summary of the Invention

[0005] In order to solve the problem that existing elevator brakes lack cleaning and self-inspection mechanisms, the present invention aims to provide a cleaning device for elevator brakes.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cleaning device for elevator brakes, including a mounting base, a traction machine, a brake wheel, and a traction sheave for use on one side of the mounting base, and an array of traction grooves on the traction sheave. A brake for use with the brake wheel is provided on the mounting base, and a lifting mechanism is provided on the other side of the mounting base. A first cleaning mechanism and a limiting mechanism for use are provided at the lower end of the lifting mechanism, and a self-inspection mechanism for use is provided at the upper end of the lifting mechanism. A second cleaning mechanism for use is provided on the lifting mechanism. The combined use of the first cleaning mechanism and the second cleaning mechanism can effectively clean the outer wall of the brake wheel and the corresponding part of the brake shoe, as well as the inner wall of the traction groove. The combined use of the lifting mechanism and the limiting mechanism facilitates the replacement of the worn first cleaning mechanism. The combined use of the lifting mechanism and the self-inspection mechanism can promptly and accurately remind elevator maintenance personnel to inspect the wire rope and traction sheave when the height difference between the wire ropes exceeds the normal range.

[0007] Preferably, the lifting mechanism includes a mounting bracket, which is fixedly mounted on a mounting base. An electric telescopic rod is fixedly inserted into the upper end of the mounting bracket. A through-hole is formed at the upper end of the mounting bracket, and the electric telescopic rod is fixedly inserted into the through-hole. A lifting bracket is fixedly sleeved at the output end of the electric telescopic rod, and one end of the lifting bracket is slidably inserted into the mounting bracket. A sliding groove is formed at the lower end of the mounting bracket, and the lower end of the lifting bracket is slidably inserted into the sliding groove. Two guide vertical rods are fixedly inserted into one end of the mounting base, and two guide vertical holes are formed at the bottom end of the lifting bracket, with the guide vertical rods slidably inserted into the guide vertical holes.

Symmetrically distributed arc-shaped mounting plates are detachably mounted on the first rotating rod, and mounting plates are fixedly mounted on the outer wall of the arc-shaped mounting plates. The system is equipped with a cleaning groove brush that can be movably engaged within the traction groove. A first gear and a cleaning ring brush are fixedly sleeved on a first rotating rod, with the cleaning ring brush fitting against the outer wall of the brake wheel away from the traction wheel. A drive gear ring is fixedly sleeved on the outer side of the brake wheel near the traction wheel and meshes with the first gear. The second cleaning mechanism includes a cleaning sleeve, which is fixedly installed at both ends of a mounting bracket. A rotating hole is opened through the cleaning sleeve, and a second rotating rod is rotatably inserted into the rotating hole. A cleaning fan blade is fixedly sleeved at one end of the second rotating rod. An array of air inlet holes is opened through one side of the cleaning sleeve, and an air outlet hole is opened through the other side of the cleaning sleeve. A cleaning guide tube that works with the air outlet hole is fixedly installed on the cleaning sleeve and works with the brake wheel and brake. A second gear is fixedly sleeved at the end of the second rotating rod and meshes with the drive gear ring.

[0008] Preferably, the limiting mechanism includes a first spring and a limiting rod. One end of the arc-shaped mounting plate is provided with a matching mounting countersunk hole and a limiting countersunk hole. The first spring is fixedly installed on the inner wall of the mounting countersunk hole, and the end of the first spring is fixedly connected to a limiting slide plate. The inner wall of the mounting countersunk hole is provided with a mounting recess, and a limiting slide rod is fixedly inserted into the mounting recess. One end of the limiting slide plate is provided with a limiting slide hole, and the limiting slide rod slides through the limiting slide hole. One end of the limiting slide plate is fixedly installed with a limiting pin, and the limiting pin on one arc-shaped mounting plate can be slidably inserted into the limiting countersunk hole on another arc-shaped mounting plate. The limiting rod is fixedly installed on the inner wall of the arc-shaped mounting plate, and the limiting rod has a symmetrical structure. The outer wall of the first rotating rod is provided with symmetrically arranged limiting holes, and the limiting rod can be slidably inserted into the limiting holes.

[0009] Preferably, the self-testing mechanism includes a buzzer alarm, a fixed insert rod, and a self-testing slide rod. The buzzer alarm is fixedly inserted into the lifting bracket. A fixed insert hole is opened through the upper end of the lifting bracket, and the buzzer alarm is fixedly inserted into the fixed insert hole. An array of mounting through holes is opened through one end of the lifting bracket. The fixed insert rod is fixedly inserted into the mounting through hole near the buzzer alarm, and a first guide rod is fixedly installed at the upper end of the fixed insert rod. The self-testing slide rod is slidably inserted into the mounting through hole away from the buzzer alarm. A second guide rod and a third guide rod are fixedly installed at the upper ends of the four self-testing slide rods near the fixed insert rod, and a third guide rod is fixedly installed at the upper end of the self-testing slide rod away from the fixed insert rod. The third guide rod and the second guide rod are staggered. The second guide rod and the first guide rod are not on the same horizontal line.

A second spring is fixedly installed at the bottom end of the installation collar, and the bottom end of the second spring is fixedly connected to the lifting bracket.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. Through the coordinated use of the first cleaning mechanism and the second cleaning mechanism, the cleaning ring brush and the two arc-shaped mounting plates can be driven to rotate synchronously, thereby driving the two cleaning groove brushes to rotate synchronously. This effectively cleans the outer wall of the corresponding part of the brake wheel and brake shoe, as well as the inner wall of the traction groove. It also quickly guides air between the brake wheel and brake shoe, thereby avoiding insufficient braking force of the brake and insufficient traction force of the traction wheel, thus effectively ensuring the braking effect of the brake and the traction effect of the traction wheel.

[0012] 2. Through the coordinated use of the lifting mechanism and the limiting mechanism, the arc-shaped mounting plate and the cleaning groove brush can be easily lifted and lowered, and the connection and fixation of the two arc-shaped mounting plates and the first rotating rod are facilitated. In addition, the arc-shaped mounting plate is easily disassembled, which facilitates the replacement of the worn cleaning groove brush, and thus facilitates the operation and use of the elevator maintenance personnel.

[0013] 3. By using the lifting mechanism and the self-inspection mechanism in conjunction, the self-inspection slide bar can be easily raised and lowered. This allows the power to be turned on and the buzzer alarm to be triggered when the height difference between the wire ropes exceeds the normal range. This enables the self-inspection of the height difference of the wire ropes and timely and accurate reminders to elevator maintenance personnel to inspect the wire ropes and traction sheaves. This eliminates the need for manual inspection by elevator maintenance personnel, saving manpower and improving inspection efficiency and accuracy. It also effectively avoids safety hazards caused by manual omissions or errors in inspection. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example: Figure 1-9As shown, the present invention provides a cleaning device for an elevator brake, including a mounting base 1. One side of the mounting base 1 is provided with a traction machine 2, a brake wheel 21, and a traction sheave 22 for cooperative use. The traction sheave 22 has arrayed traction grooves 23. The mounting base 1 is provided with a brake 3 for cooperative use with the brake wheel 21. The brake 3 includes a magnet and brake shoes, etc., which is prior art and will not be described in detail here. The other side of the mounting base 1 is provided with a lifting mechanism 4. The lower end of the lifting mechanism 4 is provided with a first cleaning mechanism 5 and a limiting mechanism 6 for cooperative use. The upper end of the lifting mechanism 4 is equipped with a self-inspection mechanism 7 for use with it. The lifting mechanism 4 is equipped with a second cleaning mechanism 8 for use with it. The use of the first cleaning mechanism 5 and the second cleaning mechanism 8 together can effectively clean the outer wall of the brake wheel 21 and the corresponding part of the brake shoe, as well as the inner wall of the traction groove 23. The use of the lifting mechanism 4 and the limit mechanism 6 together facilitates the replacement of the worn first cleaning mechanism 5. The use of the lifting mechanism 4 and the self-inspection mechanism 7 together can promptly and accurately remind elevator maintenance personnel to inspect the wire rope and traction wheel 22 when the height difference between the wire ropes exceeds the normal range.

[0027] The lifting mechanism 4 includes a mounting bracket 41, which is fixedly mounted on the mounting base 1. An electric telescopic rod 42 is fixedly inserted into the upper end of the mounting bracket 41. A through hole 46 is provided through the upper end of the mounting bracket 41, and the electric telescopic rod 42 is fixedly inserted into the through hole 46. The through hole 46 ensures the stable installation of the electric telescopic rod 42. A lifting bracket 43 is fixedly sleeved at the output end of the electric telescopic rod 42, and one end of the lifting bracket 43 is slidably inserted into the mounting bracket 41. A sliding groove 47 is provided through the lower end of the mounting bracket 41, and the lower end of the lifting bracket 43... The lifting bracket 43 is slidably inserted into the sliding groove 47. Two guide rods 44 are fixedly inserted into one end of the mounting base 1, and two guide holes 45 are opened through the bottom end of the lifting bracket 43. The guide rods 44 are slidably inserted into the guide holes 45. The cooperation between the guide rods 44 and the guide holes 45 plays a limiting and guiding role in the movement adjustment of the lifting bracket 43. The first cleaning mechanism 5 includes a first rotating rod 51 and a drive gear ring 52. A rotating through hole 48 is opened through the lower end of the lifting bracket 43. The first rotating rod 51 is rotatably inserted into the rotating through hole 48, and symmetrically distributed arc-shaped mounting plates 5 are detachably provided on the first rotating rod 51. 3. A cleaning groove brush 54 is fixedly installed on the outer wall of the arc-shaped mounting plate 53, and the cleaning groove brush 54 can be movably locked in the traction groove 23. A first gear 55 and a cleaning ring brush 56 are fixedly sleeved on the first rotating rod 51, and the cleaning ring brush 56 is in contact with the outer wall of the brake wheel 21 away from the traction wheel 22. The drive gear ring 52 is fixedly sleeved on the outer side of the brake wheel 21 near the traction wheel 22, and the drive gear ring 52 meshes with the first gear 55. The second cleaning mechanism 8 includes a cleaning sleeve 81, which is fixedly installed at both ends of the mounting bracket 41, and a rotating through hole 82 is opened through the cleaning sleeve 81. A second rotating rod 83 is rotatably inserted into the perforation 82, and a cleaning fan blade 84 is fixedly sleeved on one end of the second rotating rod 83. An array of air inlet perforations 85 are opened through one side of the cleaning sleeve 81, and an air outlet hole 86 is opened through the other side of the cleaning sleeve 81. A cleaning guide 87 that works with the air outlet hole 86 is fixedly installed on the cleaning sleeve 81, and the cleaning guide 87 works with the brake wheel 21 and the brake 3. The end of the cleaning guide 87 works with the brake wheel 21 and the brake shoe. A second gear 88 is fixedly sleeved on the end of the second rotating rod 83, and the second gear 88 meshes with the drive gear ring 52.

[0028] By adopting the above technical solution, during use, the brake wheel 21 will drive the drive gear ring 52 to rotate synchronously, thereby driving the first gear 55 and the second gear 88 to rotate synchronously, which in turn drives the first rotating rod 51 and the second rotating rod 83 to rotate synchronously, further driving the cleaning ring brush 56 and the two arc-shaped mounting plates 53 to rotate synchronously, thereby driving the two cleaning groove brushes 54 to rotate synchronously, thus effectively cleaning the outer wall of the brake wheel 21 and the corresponding part of the brake shoe, as well as the inner wall of the traction groove 23. At the same time, the second rotating rod 83 will drive the cleaning fan blade 84 to rotate, thereby drawing air into the cleaning sleeve 81 through the air inlet perforation 85 and quickly guiding it into the cleaning duct 87 through the air outlet vent 86. Subsequently, the air will be quickly guided between the brake wheel 21 and the brake shoe, thereby avoiding the phenomenon of insufficient braking force of the brake 3 and insufficient traction force of the traction wheel 22, thus effectively ensuring the braking effect of the brake 3 and the traction effect of the traction wheel 22.

[0029] The limiting mechanism 6 includes a first spring 61 and a limiting rod 62. One end of the arc-shaped mounting plate 53 has a matching mounting countersunk hole 57 and a limiting countersunk hole 58. The first spring 61 is fixedly mounted on the inner wall of the mounting countersunk hole 57, and a limiting slide plate 63 is fixedly connected to the end of the first spring 61. A mounting recess 510 is provided on the inner wall of the mounting countersunk hole 57, and a limiting slide rod 65 is fixedly inserted into the mounting recess 510. One end of the limiting slide plate 63 has a limiting slide hole 66, and the limiting slide rod 65 slides through the limiting slide hole 66. The combination of 65 and the limiting sliding hole 66 plays a limiting and guiding role in the movement adjustment of the limiting slide plate 63. One end of the limiting slide plate 63 is fixedly installed with a limiting pin 64, and the limiting pin 64 on one arc-shaped mounting plate 53 can be slidably inserted into the limiting countersunk hole 58 on another arc-shaped mounting plate 53. The limiting rod 62 is fixedly installed on the inner wall of the arc-shaped mounting plate 53, and the limiting rod 62 has a symmetrical structure. The outer wall of the first rotating rod 51 is provided with symmetrically arranged limiting holes 59, and the limiting rod 62 can be slidably inserted into the limiting holes 59.

[0030] By adopting the above technical solution, during use, after the maintenance work is completed, the elevator maintenance personnel need to pull the two limit slide plates 63 simultaneously, which can drive the two limit slide plates 63 to move in opposite directions, thereby driving the two limit pins 64 to move in opposite directions and stretching the first spring 61. When the limit pins 64 are completely separated from the corresponding limit countersunk holes 58, the two arc-shaped mounting plates 53 are pulled to move in opposite directions, thereby enabling the limit rods 62 to separate from the corresponding limit holes 59. When the limit rods 62 are completely separated from the limit holes 59, the two worn cleaning groove brushes 54 are removed, and then the two new cleaning groove brushes 54 are reset and fixed according to the above steps.

[0031] The self-testing mechanism 7 includes a buzzer 71, a fixed insert 72, and a self-testing slide bar 73. The buzzer 71 is fixedly inserted into the lifting bracket 43. A fixed insert hole 410 is provided through the upper end of the lifting bracket 43, and the buzzer 71 is fixedly inserted into the fixed insert hole 410. An array of mounting through holes 49 are provided through one end of the lifting bracket 43. The fixed insert 72 is fixedly inserted into the mounting through hole 49 near the buzzer 71, and a first guide rod 74 is fixedly installed at the upper end of the fixed insert 72. The self-testing slide bars 73 are slidably inserted into the mounting through holes 49 away from the buzzer 71. A second guide rod 75 and a third guide rod 76 are fixedly installed at the upper ends of the four self-testing slide bars 73 near the fixed insert 72. A third guide rod 76 is fixedly installed on the upper end of the self-testing slide bar 73, and the third guide rod 76 and the second guide rod 75 are staggered. The second guide rod 75 and the first guide rod 74 are not on the same horizontal line, so as to ensure that the first guide rod 74 and the second guide rod 75 are on the same horizontal line during the start of the test operation and under normal conditions where there is no height difference in the wire rope. When the third guide rod 76 contacts the first guide rod 74 or the third guide rod 76 contacts the second guide rod 75, the buzzer alarm 71 will be powered on. This is the prior art and will not be described in detail here. The upper end of the self-testing slide bar 73 is fixedly sleeved with an installation collar 77, and the bottom end of the installation collar 77 is fixedly installed with a second spring 78, and the bottom end of the second spring 78 is fixedly connected to the lifting bracket 43.

[0032] By adopting the above technical solution, during elevator maintenance, the brake wheel 21 is locked by the brake 3, and then the electric telescopic rod 42 is activated, which drives the lifting bracket 43 to move downwards. This, in turn, drives the cleaning groove brush 54, the first gear 55, the cleaning ring brush 56, the buzzer alarm 71, the fixing rod 72, and the self-test slide rod 73 to move downwards. This further separates the first gear 55 from the drive gear ring 52. When the lifting bracket 43 moves to its lowest point, the electric telescopic rod 42 is closed. At this time, the self-test slide rod 73 will contact the corresponding wire rope and the second spring 78 will be in a stretched state. If the height difference between the wire ropes is within the normal range, the second spring 78 will drive the corresponding self-test slide rod 73 to move autonomously. However, the first guide rod 74 and the corresponding third guide rod 76, as well as the other third guide rods 76, will not move downwards. The second guide rod 75 will not make contact, thus preventing the triggering of the buzzer alarm 71. If the height difference between the wire ropes exceeds the normal range, the second spring 78 will drive the self-checking slide rod 73 corresponding to the abnormal wire rope to continue moving downwards. This will allow the second guide rod 75 or the third guide rod 76 on the corresponding self-checking slide rod 73 to make contact with the adjacent first guide rod 74 or the corresponding third guide rod 76 or the second guide rod 75 on the adjacent self-checking slide rod 73. This will connect the power supply and trigger the buzzer alarm 71, thereby enabling self-checking of the height difference of the wire rope and timely and accurate reminders to elevator maintenance personnel to inspect the wire rope and traction sheave 22. This eliminates the need for manual inspection by elevator maintenance personnel, saving manpower and improving inspection efficiency and accuracy. Furthermore, it can effectively avoid the existence of safety hazards due to manual omissions or errors in inspection.

[0033] Working principle: During use, the brake wheel 21 drives the drive gear ring 52 to rotate synchronously, which in turn drives the first gear 55 and the second gear 88 to rotate synchronously, which in turn drives the first rotating rod 51 and the second rotating rod 83 to rotate synchronously, which in turn drives the cleaning ring brush 56 and the two arc-shaped mounting plates 53 to rotate synchronously, which in turn drives the two cleaning groove brushes 54 to rotate synchronously, thus effectively cleaning the outer wall of the brake wheel 21 and the corresponding part of the brake shoe and the inner wall of the traction groove 23. At the same time, the second rotating rod 83 drives the cleaning fan blade 84 to rotate, which draws air into the cleaning sleeve 81 through the air inlet perforation 85 and quickly guides it into the cleaning duct 87 through the air outlet vent 86. Subsequently, the air will be quickly guided between the brake wheel 21 and the brake shoe, thus avoiding the phenomenon of insufficient braking force of the brake 3 and insufficient traction force of the traction wheel 22, thereby effectively ensuring the braking effect of the brake 3 and the traction effect of the traction wheel 22.

[0034] When the elevator is being maintained, the brake wheel 21 is locked by brake 3, and then the electric telescopic rod 42 is activated, which moves the lifting support 43 downward. This, in turn, moves the cleaning brush 54, the first gear 55, the cleaning ring brush 56, the buzzer alarm 71, the fixing rod 72, and the self-test slide rod 73 downward. This further separates the first gear 55 from the drive gear ring 52. When the lifting support 43 reaches its lowest point, the electric telescopic rod 42 is closed. At this time, the self-test slide rod 73 will contact the corresponding wire rope and the second spring 78 will be in a stretched state. If the height difference between the wire ropes is within the normal range, the second spring 78 will move the corresponding self-test slide rod 73 autonomously. However, the first guide rod 74 and the corresponding third guide rod 76, as well as the other third guide rods 76 and the corresponding second guide rod 75, will not move. The two springs will not make contact, thus preventing the triggering of the buzzer alarm 71. If the height difference between the wire ropes exceeds the normal range, the second spring 78 will drive the corresponding self-checking slide bar 73 of the abnormal wire rope to continue to move downward. This will allow the second guide bar 75 or the third guide bar 76 on the corresponding self-checking slide bar 73 to contact the adjacent first guide bar 74 or the corresponding third guide bar 76 or the second guide bar 75 on the adjacent self-checking slide bar 73. This will connect the power supply and trigger the buzzer alarm 71, thereby enabling the self-checking of the height difference of the wire rope and timely and accurately reminding elevator maintenance personnel to inspect the wire rope and traction sheave 22. This eliminates the need for manual inspection by elevator maintenance personnel, saving manpower and improving inspection efficiency and accuracy. Furthermore, it can effectively avoid the phenomenon of safety hazards due to manual omissions or errors in inspection.

[0035] After the maintenance work is completed, the elevator maintenance personnel need to pull the two limit slide plates 63 simultaneously, which will cause the two limit slide plates 63 to move in opposite directions, thereby causing the two limit pins 64 to move in opposite directions and stretch the first spring 61. When the limit pins 64 are completely separated from the corresponding limit countersunk holes 58, the two arc-shaped mounting plates 53 are pulled to move in opposite directions, thereby causing the limit rods 62 to separate from the corresponding limit holes 59. When the limit rods 62 are completely separated from the limit holes 59, the two worn cleaning groove brushes 54 are removed. Then, the two new cleaning groove brushes 54 are reset and fixed according to the above steps, and the electric telescopic rod 42 is restarted, which will cause the lifting bracket 43 to reset and the first gear 55 to mesh with the drive gear ring 52 again.

[0036] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
