Description

Technical Field

[0001] At least one embodiment of the utility model relates to a brake, and in particular to a caliper disc brake for a traction machine, a traction machine and an elevator. Background Art

[0002] The caliper disc brake in the elevator system has the characteristics of low noise and compact structure. It is currently the most commonly used brake type for elevator traction machines. For traction machines equipped with caliper disc brakes, the caliper disc brake is usually installed on the traction machine base in an axial floating manner through a pin shaft. After the caliper disc brake is powered on, the brake pad on one side of the caliper disc brake is separated from the brake disc under the action of electromagnetic attraction, while the brake pad on the other side is still in contact with the brake disc. When the traction machine starts to rotate, the impact force generated by the collision between the brake disc and the contacting brake pad overcomes the axial friction between the base of the caliper disc brake and the pin shaft, causing the brake pad on the other side of the caliper disc brake to move in the direction of separation from the brake disc and disengage from the brake disc.

[0003] During the use of the traction machine, the axial friction force increases due to rust on the pin surface or uneven installation, so that the impact force between the brake disc and the brake pad of the caliper disc brake used for the traction machine is insufficient to overcome the axial friction between the base of the caliper disc brake and the pin. The brake pad of the caliper disc brake cannot be completely disengaged from the brake disc, and a slight friction sound will be generated when the traction machine is running. In addition, when the electromagnetic force of the caliper disc brake is too large, leakage magnetic attraction will be generated on the surface of the brake disc, causing the brake pad to be adsorbed on the surface of the brake disc. Excessive friction will cause the brake pad to lose powder or reduce the braking torque, which will seriously affect the safe operation of the caliper disc brake.

[0004] In order to solve the above problems, the existing caliper disc brake for traction machine is usually equipped with elastic parts and limit assemblies at both ends of the pin shaft. Therefore, during maintenance, the caliper disc brake needs to be disassembled from the traction machine to complete the disassembly and assembly between the elastic part and the limit assembly and the pin shaft, which is inconvenient for maintenance on-site.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0041] According to the inventive concept of one aspect of the utility model, a caliper disc brake for a traction machine is provided, comprising: a pin shaft, a first end of the pin shaft extends into a machine base of the traction machine; a base, movably mounted on the pin shaft, the base being constructed as a block with an opening on the lower side; an armature, reciprocatingly mounted in a lateral direction on a first inner wall of the base on a side of the machine base away from the traction machine; a first brake pad, mounted on the armature, and reciprocatingly moving linearly in the lateral direction with the armature; a second brake pad, mounted on a second inner wall of the base facing the first inner wall, the first brake pad and the second brake pad being respectively and parallelly arranged on opposite sides of the brake disc of the traction machine; and a position adjustment portion, mounted on an outer wall of the base on a side where the armature is mounted, and being constructed so that when the armature drives the first brake pad to leave the brake disc, the base is driven to move toward the machine base relative to the pin shaft, so that a gap is generated between the brake disc and the second brake pad.

[0042] Figure 1 It is a schematic diagram of assembling a caliper disc brake for a traction machine and a traction machine according to an embodiment of the utility model; Figure 2 The utility model is a schematic diagram of assembling a caliper disc brake for a traction machine, a brake disc of the traction machine and a machine base according to an embodiment of the utility model.

[0043] According to the exemplary embodiment of the present invention, please refer to Figure 1-Figure 2, a caliper disc brake for a traction machine is provided, comprising a pin shaft 7, a base 1, an armature 3, a first brake pad 4, a second brake pad 5 and a position adjustment portion 6. The first end of the pin shaft 7 extends into the base 21 of the traction machine 2. The base 1 is movably mounted on the pin shaft, and the base 1 is constructed as a block with an opening on the lower side. The armature 3 is reciprocatingly mounted on the first inner wall 11 of the base 1 on the side of the base 21 away from the traction machine 2 in a lateral direction. The first brake pad 4 is mounted on the armature 3 and moves linearly and reciprocatingly in the lateral direction with the armature 3. The second brake pad 5 is mounted on the second inner wall 12 of the base 1 facing the first inner wall 11, and the first brake pad 4 and the second brake pad 5 are respectively arranged in parallel on the opposite sides of the brake disc 221 of the traction machine 2. The position adjustment part 6 is installed on the outer wall of the base 1 on the side where the armature 3 is installed, and is constructed to drive the base 1 to move toward the machine base 21 relative to the pin shaft 7 when the armature 3 drives the first brake pad 4 to leave the brake disc 221, so that a gap is generated between the brake disc 221 and the second brake pad 5.

[0044] In this embodiment, by installing a position adjustment part 6 on the outer wall of the base 1 on the side where the armature 3 is installed, when the armature 3 drives the first brake pad 4 to leave the brake disc 221, the base 1 is sufficient to overcome the axial friction between the base 1 and the pin 7 under the action of the driving force of the position adjustment part 6, and pushes the base 1 to move toward the machine base 21 relative to the pin 7, so that a gap is generated between the brake disc 221 and the second brake pad 5, thereby avoiding the friction sound caused by the continuous collision between the second brake pad 5 and the brake disc 221 when the traction machine is running.

[0045] It should be noted that, in this embodiment, the base 1 is movably mounted on the pin 7, which means that when the armature 3 drives the first brake pad 4 to leave the brake disc 221, the base 1 can move relative to the pin 7 toward the base 21 under the drive of the position adjustment unit 6. Figure 2 The left and right direction in .

[0046] Figure 3 It is a schematic diagram of the assembly between the caliper disc brake and the brake disc of the traction machine in the case of power-off braking of the caliper disc brake used for the traction machine according to an embodiment of the utility model; Figure 4 The utility model is a schematic diagram of the assembly between the caliper disc brake and the brake disc of the traction machine when the caliper disc brake is powered but not braked.

[0047] In some exemplary embodiments, referring to Figure 2-Figure 4The position adjustment part 6 includes a guide rod 61, an elastic member 62 and a support assembly 63. The guide rod 61 extends in the transverse direction, and the first end of the guide rod 61 extends into the end surface of the second end of the pin shaft 7, for example, by means of a threaded connection. The elastic member 62 is sleeved on the second end of the pin shaft 7 extending out of the base 1, and abuts against the outer wall of the base 1 on the side where the armature 3 is installed. The support assembly 63 is immovably sleeved on the outside of the guide rod 61 and is located at the end of the elastic member 62 opposite to the base 1, so that the elastic member 62 is compressed when the armature 3 drives the first brake pad 4 to press the brake disc 221, and when the armature 3 drives the first brake pad 4 to leave the brake disc 221, the base 1 is elastically pushed to move relative to the pin shaft 7 toward the base 21 of the traction machine 2. In some exemplary embodiments, the guide rod may include a screw or a bolt.

[0048] Through the above-mentioned arrangement, when the caliper disc brake is energized and not braking, the armature 3 drives the first brake pad 4 to leave the brake disc 223. Under the action of the elastic force of the elastic member 62, sufficient driving force is provided to overcome the axial friction between the base 1 and the pin 7, so that the base 1 moves relative to the pin 7 toward the base 21 of the traction machine 2, thereby separating the brake disc 221 from the second brake pad 5.

[0049] In some exemplary embodiments, referring to Figure 2-Figure 4 The position adjustment part 6 further includes a limit assembly 64. One end of the limit assembly 64 is movably mounted on the outer portion of the guide rod 61 opposite to the pin shaft 7, and the other end is mounted on the base 1. The limit assembly 64 is configured to limit the spacing between the limit assembly 64 and the support assembly 63 in the lateral direction when the armature 3 drives the first brake pad 4 to press the brake disc 221.

[0050] In this embodiment, the spacing between the limit assembly 64 and the support assembly 63 along the lateral direction is limited when the armature 3 drives the first brake pad 4 to press the brake disc 221, so as to limit the spacing between the brake disc 221 and the second brake pad 5 along the lateral direction when the armature 3 drives the first brake pad 4 to leave the brake disc 221.

[0051] In some exemplary embodiments, referring to Figure 2-Figure 4 The support assembly 63 includes a support member 631 and a fastener 632. The support member 631 is sleeved on the guide rod 61, and one side abuts against the elastic member 62. The fastener 632 is sleeved on the guide rod 61 and abuts against the other side of the support member 631 to lock the support member 631 and the elastic member 62 on the pin 7.

[0052] Through the above arrangement, the elastic member 62 is locked on the pin shaft 7 under the action of the support member 631 and the fastener 632 .

[0053] It should be noted that, in this embodiment, the support member 631 may be a gasket, and the fastener 632 may be a fastening screw.

[0054] Figure 5 It is a schematic plan view of a base of a caliper disc brake for a traction machine according to an embodiment of the utility model.

[0055] In some exemplary embodiments, referring to Figure 2-Figure 5 , a first connecting hole 14 is provided on the base 1. The limiting assembly 64 includes a first connecting plate 641 and a second connecting plate 642 which are connected to each other. The first connecting plate 641 is movably mounted on the guide rod 61. The second connecting plate 642 extends in the transverse direction, and a plurality of second connecting holes 6421 which are adapted to the first connecting hole 14 are provided in the transverse direction on the second connecting plate 642. By adjusting different second connecting holes 6421 to be combined with the first connecting hole 14, the spacing between the first connecting plate 641 and the fastener 632 can be adjusted. Among them, the spacing between the first connecting plate 641 and the fastener 632 is equal to the spacing between the brake disc 221 and the second brake pad 5 when the armature 3 drives the first brake pad 4 to leave the brake disc 221.

[0056] In this embodiment, if Figure 2-Figure 4 As shown, by adjusting the different second connecting holes 6421 arranged on the second connecting plate 642 in combination with the first connecting hole 14 arranged on one side extending along the longitudinal direction of the base 1, the distance between the first connecting plate 641 and the fastener 632 can be adjusted when the armature 3 drives the first brake pad 4 to press the brake disc 211, thereby adjusting the distance between the brake disc 221 and the second brake pad 5 when the armature 3 drives the first brake pad 4 to leave the brake disc 211.

[0057] In detail, Figure 3 As shown, when the armature 3 drives the first brake pad 4 to press the brake disc 221, the base 1 moves away from the base 21 of the traction machine 2 relative to the pin 7 ( Figure 3 Since the fastener 632 is immovably mounted on the guide rod 61, the elastic member is compressed. At the same time, since the first connecting plate 641 moves with the base 1, a gap is generated between the first connecting plate 641 and the fastener 632. On the other hand, Figure 4 As shown, when the armature 3 drives the first brake pad 4 to leave the brake disc 221, the elastic member 62 stretches due to the disappearance of the external force and overcomes the axial friction between the base 1 and the pin 7 to elastically drive the base 1 to move relative to the pin 7 toward the base 21 of the traction machine 2 ( Figure 3The limiting assembly 64 moves with the base 1 relative to the pin shaft 7 toward the base 21 of the traction machine 2, and the first connecting plate 641 moves relative to the guide rod 61 toward the fastener 632, so that after the first connecting plate 641 abuts against the fastener 632, the base 1 stops moving relative to the pin shaft 7 toward the base 21 of the traction machine 2, thereby preventing the first brake pad 4 from abutting against the brake disc 221 during the movement of the base 1 relative to the pin shaft 7 toward the base 21, thereby ensuring that there is a gap between the brake disc 221 and the first brake pad 4, so that there are gaps between the two sides of the brake disc 211 and the first brake pad 4 and the second brake pad 5 respectively, thereby preventing the brake disc 211 from colliding with the first brake pad 4 or the second brake pad 5 to generate friction noise.

[0058] In some exemplary embodiments, referring to Figure 3-Figure 4 , the spacing between the first connecting plate 641 and the fastener 632 is equal to one half of the distance that the armature 3 moves relative to the base 1 when the armature 3 drives the first brake pad 4 to leave the brake disc 221. In this way, when the armature 3 drives the first brake pad 4 to leave the brake disc 221, due to the movement of the base 1 relative to the pin 7 toward the base 21, the spacing between the first connecting plate 641 and the fastener 632 is set to be equal to one half of the distance that the armature 3 moves relative to the base 1, so that the spacing between the brake disc 211 and the first brake pad 4 and the spacing between the brake disc 211 and the second brake pad 5 can be equal.

[0059] Further, refer to Figure 2 A plurality of second connecting holes 6421 are evenly spaced on the second connecting plate 642, so as to accurately define the distance between the first connecting plate 641 and the fastener 632 when the armature 3 drives the first brake pad 4 to press the brake disc 221, and to accurately define the distance between the brake disc 221 and the second brake pad 5 when the armature 3 drives the first brake pad 4 to leave the brake disc 221.

[0060] In some exemplary embodiments, referring to Figure 3-Figure 4 The elastic member 62 is a tubular elastic body made of rubber, a corrugated spring and a disc spring.

[0061] In some exemplary embodiments, referring to Figure 3-Figure 4 The armature 3 includes a connecting rod 31 and an armature body 32. The connecting rod 31 extends in the lateral direction, and one end thereof extends into the interior of the base 1. The armature body 32 extends in the vertical direction, and is slidably sleeved on the exterior of the connecting rod 31, and reciprocates and moves linearly along the axial direction of the connecting rod 31.

[0062] Through the above-mentioned arrangement, when the caliper disc brake is energized and not braking, under the action of electromagnetic attraction, the armature body 32 moves along the axial direction of the connecting rod 31 toward the first inner wall 11 of the base 1, so as to drive the first brake pad 4 to move toward the first inner wall 11 of the base 1, so that the first brake pad 4 is separated from the brake disc 221.

[0063] It should be noted that in this embodiment, a slot 15 extending in the transverse direction is provided on one side of the base 1 away from the base 21 of the traction machine 2 , one end of the connecting rod 31 extends into the base 1 through the slot 15 , and the other end extends to the outside of the base 1 .

[0064] In this embodiment, when the caliper disc brake is powered on and not in braking state, under the action of electromagnetic force, the armature body 32 moves toward the first inner wall 11 of the base 1 along the axial direction of the connecting rod 31, so as to drive the first brake pad 4 to move toward the first inner wall 11 of the base 1, so that the first brake pad 4 leaves the brake disc 221. Furthermore, the elastic member 62 drives the base 1 to move toward the base 21 of the traction machine 2 relative to the pin shaft 7, so that a gap is generated between the brake disc 221 and the second brake pad 5. Furthermore, during the movement of the limit assembly 64 along with the base 1 relative to the pin shaft 7 toward the base 21 of the traction machine 2, the first connecting plate 641 moves relative to the guide rod 61 toward the fastener 632. When the first connecting plate 641 abuts against the fastener 632, the base 1 stops moving relative to the pin shaft 7 toward the base 21 of the traction machine 2, so as to avoid the brake disc 221 abutting against the first brake pad 4 during the movement of the base 1 relative to the pin shaft 7 toward the base 21 of the traction machine 2, thereby ensuring a gap between the brake disc 221 and the first brake pad 4.

[0065] In addition, in order to overcome the technical defect that the impact force between the brake disc and the brake pad in the caliper disc brake used for the traction machine in the prior art is not enough to overcome the axial friction between the base and the pin of the caliper disc brake, the brake pad of the caliper disc brake cannot be completely disengaged from the brake disc. In the prior art, an elastic member is arranged on one side of the pin of the caliper disc brake, and a limit assembly is arranged on the other side. Therefore, during maintenance, it is usually necessary to remove the caliper disc brake from the traction machine before the elastic member and the limit assembly can be disassembled and assembled at both ends of the pin of the caliper disc brake. In the traction machine used for the elevator, the caliper disc brake is a safety component. The disassembly and assembly of the caliper disc brake needs to be strictly carried out in accordance with the operating procedures, and additional tooling needs to be set up at the maintenance site for support, which makes the operation at the maintenance site complicated and the maintenance cost high. In the caliper disc brake for the traction machine of the utility model, the position adjustment part 6 is installed on the outer wall of the base 1 on the side where the armature 3 is installed, so that during the disassembly and assembly of the position adjustment part 6, there is no need to remove the caliper disc brake from the traction machine, and the caliper disc brake can be directly installed on one side of the caliper disc brake, which greatly reduces the work content at the maintenance site and improves the work efficiency at the maintenance site.

[0066] According to the exemplary embodiment of the present invention, please refer to Figure 1-Figure 2 , a traction machine is provided, comprising a machine base 21, a main shaft 23, a rotor assembly 22, two bearings 24 and the caliper disc brake for the traction machine described in the above embodiment. The main shaft 23 extends in the lateral direction and is mounted on the machine base 21. The rotor assembly 22 is sleeved on the outside of the main shaft 23, and the rotor assembly 22 comprises a traction wheel 222, a brake disc 221 and a magnetic steel mounting portion 223 connected in sequence. The two bearings 24 are respectively sleeved on both ends of the main shaft 23. The caliper disc brake for the traction machine described in the above embodiment is mounted on the machine base 21, and the first brake pad 4 and the second brake pad 5 are respectively arranged in parallel on both sides of the brake disc 221.

[0067] Through the above-mentioned arrangement, a traction machine is provided in which the caliper disc brake for the traction machine described in the above-mentioned embodiment is installed on the machine base 21, thereby avoiding the situation in which the second brake pad 5 cannot be completely disengaged from the brake disc 221 when the impact force between the brake disc 221 and the second brake pad 5 is insufficient to overcome the axial friction force between the base 1 and the pin 7, thereby avoiding the friction sound generated when the traction machine 2 is running.

[0068] It should be noted that, in this embodiment, the rotor assembly 22 is press-fitted on the outside of the main shaft 23, and the two bearings 24 are press-fitted on both ends of the main shaft 23. The main shaft 23, the rotor assembly 22 and the two bearings 24 are press-fitted to form a rotating component. The traction sheave 222 provides traction for the elevator operation, the brake disc 221 provides braking force for the elevator operation, and the magnetic steel mounting portion 223 is used to install the magnetic steel.
