Description

Technical Field

[0001] The utility model relates to the field of elevator brakes, in particular to a switch assembly with a side adjustment function. Background Technique

[0002] An elevator brake is a friction brake, which realizes the braking function of the elevator by interacting with the rotating part of the elevator traction machine; when the elevator is powered on and running, the brake is released to allow the elevator to run normally; when the elevator needs to stop or encounters an abnormal situation, the brake acts quickly to stop the elevator.

[0003] An elevator brake generally includes components such as an electromagnet, a brake arm and a brake spring, a brake pad, a brake disc, and a switch assembly; among them, the switch assembly is one of the important components of the elevator brake. Due to the precise stroke of the brake, that is, the gap requirement between the two states of the traction machine being locked and released is within 0.06 mm, so the position where the switch is located has very high precision requirements.

[0004] The existing elevator brake switch assembly is usually rigidly connected.

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 creative work fall within the protection scope of the present invention.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 to 5 As shown, a switch assembly with a side adjustment function described in an embodiment of the present invention includes a bracket 1; a slide block 12 is slidably connected to the middle of the bracket 1; a switch body 13 is fixedly connected to the middle of the slide block 12; an elastic piece 14 is fixedly connected to the middle of the bracket 1; the elastic piece 14 is located at the top of the switch body 13; a first spring 15 is fixedly connected to the middle of the bracket 1; the first spring 15 and the slide block 12 are fixedly connected; a bolt 16 is installed in the middle of the bracket 1; a fixed groove 17 is formed in the inner side wall of the slide block 12; the inner side wall of the fixed groove 17 is inclined; the fixed groove 17 and the bolt 16 are in contact; during operation, the elastic piece 14 will be subjected to pressure and undergo elastic deformation. At this time, the elastic piece 14 will drive the switch body 13 to be in an open state. When it is necessary to adjust the gap between the elastic piece 14 and the switch body 13, the staff can rotate the bolt 16 so that the bolt 16 slides along the surface of the fixed groove 17. Because the surface of the fixed groove 17 is inclined, the slide block 12 will slide along the bracket 1 under the friction of the bolt 16 and the fixed groove 17. When the slide block 12 moves, the length of the first spring 15 will change. At the same time, the slide block 12 will drive the switch body 13 to move together, so that the distance between the switch body 13 and the elastic piece 14 changes. After adjustment, the gap between the switch body 13 and the elastic piece 14 will obtain a displacement several times larger than the contact point between the pressure and the elastic piece 14; the slide block 12 drives the switch body 13 to slide along the bracket 1 under the friction of the bolt 16 and the fixed groove 17, realizing the adjustment of the height of the slide block 12 and the switch body 13 by the device, shortening the working time required for adjusting the height of the switch body 13, and improving the convenience of adjusting the gap height between the switch body 13 and the elastic piece 14 by the device.

[0027] Please refer toFigure 3 and Figure 4 As shown, a plurality of second springs 2 are fixedly connected to the inner side wall of the fixed groove 17; the end of the second spring 2 is fixedly connected to a connecting plate 22; the connecting plate 22 is slidably connected to the fixed groove 17; a plurality of elastic rods 23 are fixedly connected to the top of the connecting plate 22; an elastic wire 24 is fixedly connected between adjacent elastic rods 23; the elastic wire 24 and the bolt 16 are arranged correspondingly; the elastic wire 24 is in a taut state under normal conditions, and the second spring 2 is also in a compressed state, causing the connecting plate 22 to approach the bolt 16. When the bolt 16 enters the fixed groove 17, the bolt 16 will come into contact with the elastic wire 24 and squeeze it. After being squeezed, the elastic wire 24 will break. At this time, the elastic rod 23 will lose the pulling force of the elastic wire 24 and approach the fixed groove 17 under its own elastic force. When the elastic rod 23 contacts the fixed groove 17, it will knock on the fixed groove 17 and transmit a signal to the staff. According to the feedback of the knock, the staff can immediately understand the degree of the moving distance of the switch body 13. When the bolt 16 moves, it will damage the elastic wire 24, causing the elastic rod 23 to knock on the fixed groove 17 under the elastic force, realizing the timely feedback of information when the device adjusts the height of the slider 12, enabling the staff to quickly master the moving distance of the bolt 16 and proceed to the next step of work, reducing the working time required to observe the moving distance of the slider 12.

[0028] Please refer to Figure 4 As shown, a plurality of third springs 3 are fixedly connected to the top of the connecting plate 22; the top of the third spring 3 is fixedly connected to a baffle 32; the baffle 32 is of an arc structure; the baffle 32 is located at the bottom of the bolt 16. During normal operation, the elastic rod 23 will approach the bolt 16 under the pulling force of the elastic wire 24. At this time, the baffle 32 will block the elastic rod 23, reducing the bending arc of the elastic rod 23, reducing the direct contact between the elastic rod 23 and the bolt 16, and reducing the friction between the elastic rod 23 and the bolt 16. At the same time, when the bolt 16 moves, it will come into contact with the baffle 32, and the baffle 32 will guide the moving trajectory of the bolt 16, enabling the bolt 16 to stably slide along the surface of the fixed groove 17, improving the stability and accuracy of the device for adjusting the slider 12.

[0029] Please refer to Figure 4 As shown, a plurality of balls 4 are rotatably connected to the inner side wall of the baffle 32; the balls 4 are arranged in an array. When the bolt 16 moves, it will come into contact with the baffle 32, and at the same time, the bolt 16 will also come into contact with the balls 4. The balls 4 will rotate under the friction, converting the sliding friction between the baffle 32 and the bolt 16 into rolling friction, reducing the resistance received by the bolt 16 when it moves, and also reducing the damage caused by friction to the surfaces of the bolt 16 and the baffle 32.

[0030] Please refer to Figures 2 to 5As shown, a pair of rivets 5 are fixedly connected to the middle part of the bracket 1; a pair of slide grooves 52 are opened in the middle part of the bracket 1 and the slider 12; the rivet 5 and the slide groove 52 are slidably connected; the rivet 5 and the slider 12 are through-set; the rivet 5 will assist in fixing the slider 12, and when the bolt 16 is rotated to make the slider 12 slide along the bracket 1, the slider 12 will move with the slide groove 52, so that the rivet 5 will slide along the slide groove 52, and the slider 12 will be affected by the friction between the rivet 5 and the slide groove 52 when moving, thereby reducing the deviation and shaking of the slider 12 when moving.

[0031] See also Figure 5 As shown, the inner wall of the slide groove 52 is symmetrically fixed with an oil bag 6; the middle part of the oil bag 6 is rotatably connected with a plurality of rotating wheels 62; lubricating oil is injected into the oil bag 6, and when the slide groove 52 moves with the slider 12, the oil bag 6 and the rotating wheel 62 will also move together, and the rotating wheel 62 will come into contact with the slide groove 52 and rotate under the action of friction. When the rotating wheel 62 rotates, the lubricating oil in the oil bag 6 will adhere to the surface, and then the rotating wheel 62 will brush the lubricating oil to the surface of the rivet 5, so as to lubricate the rivet 5, reduce the wear caused by friction between the rivet 5 and the slide groove 52, and extend the service life of the rivet 5.

[0032] See also Figure 5 As shown, a collecting box 7 is fixedly connected to the bottom of the inner wall of the slide groove 52; the collecting box 7 is located at the bottom of the rivet 5; when the rotating wheel 62 lubricates the rivet 5, there will be splashing lubricating oil, which will enter the interior of the collecting box 7 and be collected by the collecting box 7, thereby realizing the recovery and collection of the lubricating oil by the device.

[0033] Working principle: The elastic piece 14 is subjected to pressure and undergoes elastic deformation. At this time, the elastic piece 14 drives the switch body 13 to be in the on state. When it is necessary to adjust the gap between the elastic piece 14 and the switch body 13, the staff can rotate the bolt 16 so that the bolt 16 slides along the surface of the fixed groove 17. Since the surface of the fixed groove 17 is inclined, the slider 12 slides along the bracket 1 under the friction between the bolt 16 and the fixed groove 17. When the slider 12 moves, the length of the first spring 15 changes. At the same time, the slider 12 drives the switch body 13 to move together, so that the distance between the switch body 13 and the elastic piece 14 changes. After adjustment, the gap between the switch body 13 and the elastic piece 14 will obtain a displacement magnified several times compared with the contact point between the pressure and the elastic piece 14; the elastic wire 24 is in a taut state under normal conditions, and the second spring 2 is also in a compressed state, causing the connecting plate 22 to approach the bolt 16. When the bolt 16 enters the inside of the fixed groove 17, the bolt 16 contacts and squeezes the elastic wire 24. After being squeezed, the elastic wire 24 breaks. At this time, the elastic rod 23 loses the pulling force of the elastic wire 24 and approaches the fixed groove 17 under its own elastic force. When the elastic rod 23 contacts the fixed groove 17, it knocks on the fixed groove 17 and transmits a signal to the staff. The staff can understand the degree of the moving distance of the switch body 13 immediately according to the feedback of the knock; during normal operation, the elastic rod 23 approaches the bolt 16 under the pulling force of the elastic wire 24. At this time, the baffle 32 blocks the elastic rod 23, reducing the bending arc of the elastic rod 23, reducing the direct contact between the elastic rod 23 and the bolt 16, and reducing the friction between the elastic rod 23 and the bolt 16. At the same time, when the bolt 16 moves, it contacts the baffle 32, and the baffle 32 guides the moving track of the bolt 16, so that the bolt 16 can stably slide along the surface of the fixed groove 17; when the bolt 16 moves, it contacts the baffle 32, and at the same time, the bolt 16 also contacts the ball 4. The ball 4 rotates under the friction, converting the sliding friction between the baffle 32 and the bolt 16 into rolling friction; the rivet 5 assists in fixing the slider 12. When the bolt 16 is rotated to make the slider 12 slide along the bracket 1, the slider 12 drives the chute 52 to move together, so that the rivet 5 slides along the chute 52. When the slider 12 moves, it is affected by the friction between the rivet 5 and the chute 52; when the chute 52 moves with the slider 12, the oil bag 6 and the runner 62 also move together. The runner 62 contacts the chute 52 and rotates under the friction. When the runner 62 rotates, lubricating oil in the oil bag 6 adheres to its surface. Subsequently, the runner 62 coats the lubricating oil on the surface of the rivet 5; when the runner 62 lubricates the rivet 5, there will be splashing lubricating oil, and this lubricating oil will enter the inside of the collection box 7 and be collected by the collection box 7.
