Description

Technical Field

[0001] The present disclosure relates to the technical field of detection instruments and meters, and more specifically, to a detection device and method for brakes. Background Art

[0002] The caliper disc brake is small in size, compact in structure, and can be set up in multiple groups, so it is widely used in the elevator industry. The caliper disc brake is usually floatingly mounted on a pair of pins and mounted to the traction machine through the pins to achieve the braking of the elevator traction machine.

[0003] The caliper disc brake is installed floatingly on the pin shaft. After the brake is powered on, the friction plates on both sides of the brake cannot move synchronously. Usually, the friction plate on one side is separated from the friction disc under the action of electromagnetic suction, and the friction plate on the other side needs to rely on the impact force generated by the collision between the rotating brake disc and the friction plate. The impact force overcomes the axial friction between the brake and the pin shaft, so that the friction plate and the brake disc are separated. When the axial friction between the brake and the pin shaft is too large, the friction plate on one side of the brake cannot be separated from the brake disc, resulting in disc rubbing noise when the brake is running, affecting the comfort of the elevator operation. If the disc rubbing problem is not solved for a long time, the brake pad on one side of the brake will be worn for a long time, which can reduce the life of the brake and affect the safety of the elevator operation.

[0039] The detailed background technology may include other technical problems besides the technical problems solved by the claim alone.

[0040] like Figures 1 to 7 As shown, an embodiment of the present disclosure provides a detection device for a brake, including: a base 1, provided with at least one shaft 11, on which a brake 3 is slidably arranged; a force-applying structure 2, arranged on the base 1, the force-applying structure 2 has a force-applying member 21, and the force-applying member 21 can move toward the brake 3 to drive the brake 3 to slide on the shaft 11, wherein the force direction of the force-applying member 21 is parallel or colinear with the axial direction of the shaft 11; a force measuring structure 4, arranged on the force-applying structure 2 and / or the brake 3, for obtaining the force value of the force-applying member 21.

[0041] The detection object of the brake detection device in the present disclosure is the brake. There are many types of brakes. The present disclosure takes the caliper disc brake as an example to specifically explain the scheme of the present disclosure. Obviously, the detection object of the brake detection device in the present disclosure is not limited to the floating caliper brake, and other types of axial floating brakes are also applicable to the present technology.

[0042] It can be understood that the present technology can also be applied in other devices and equipment fields that require the measurement of friction between a shaft and a hole.

[0043] The base 1 is a basic component for installing the force-applying structure 2, the brake 3, and the force-measuring structure 4. It is necessary to set relevant installation holes, positioning bumps and other structures on it to realize its function as an installation base. The structural form of the base 1 can be described as a common block-shaped solid structure or a common frame structure.

[0044] See also Figure 5 As shown, the shaft 11 is mounted on the base 1, and the number of the shafts 11 depends on the number of shaft holes on the brake 3 to be tested. In this embodiment, there are two shafts 11, which are installed at intervals on the base 1. The brake 3 to be tested is slidably mounted on the shaft 11 through the shaft hole structure thereon.

[0045] In order to facilitate understanding of the installation method of the caliper disc brake on the shaft 11 in the present disclosure, one structural form of the floating caliper brake is described:

[0046] The floating caliper brake has a housing, which contains parts such as an iron core; a bushing is also arranged in the housing, and a pin is suitable for being inserted into the bushing. As described in the background technology section, the friction plate that needs to collide with the brake wheel to separate is arranged on the housing, and the magnitude of the sliding friction force of the housing on the pin directly affects whether the friction plate can be separated from the brake wheel immediately. Therefore, in the actual test of this embodiment, the shaft 11 can directly adopt the pin structure in the brake. When testing different types of brakes, the corresponding pin structures are different, and the type of shaft 11 needs to be replaced to adapt to the test needs. Of course, the shaft 11 can also be processed by itself, ensuring that the size and the friction coefficient on the circumference are consistent with the parameters of the pin used in the original brake.

[0047] There are many structural forms of the force-applying structure 2, such as a common electric push rod structure, a hydraulic or pneumatic pressure plus a telescopic shaft structure, etc. Its main function is to apply a force toward the brake 3 to drive the brake 3 to move on the shaft 11. Among them, in order to directly and conveniently obtain the friction force value between the brake 3 and the shaft 11, on the basis of ensuring that the force-applying direction is parallel or collinear with the axial direction, a force measuring structure 4 is introduced to facilitate direct acquisition of the test results.

[0048] It is understandable that the setting of ensuring that the force direction is parallel or colinear with the axial direction can restore the force state of the brake on the shaft during actual use as much as possible, making the test results more accurate. As a variation, when there is an angle between the force direction and the axial direction, the required friction force value can be obtained by force decomposition.

[0049] Since the force is mutual, the force measuring structure 4 can be arranged on the force applying structure 2 or the brake 3. The force measuring structure 4 can also be arranged on both the force applying structure 2 and the brake 3 to provide more force measuring points and improve the accuracy of the force measuring result.

[0050] There are many types of force measuring structures 4. In this embodiment, a common force measuring sensor or a push-pull force gauge is used.

[0051] It can be understood that when the brake 3 slides on the shaft 11, there is a static friction force generated from a stationary state to the beginning of sliding, and a dynamic friction force generated during the sliding process. The force value obtained in the present disclosure includes the static friction value and the dynamic friction value mentioned above. When judging whether the friction between the brake and the shaft 11 is compliant, the maximum value of the detected force value is compared with the preset friction value. As a modified implementation, in some usage scenarios, it is also possible to detect only the dynamic friction value of the brake during sliding, or the static friction value from stationary to moving.

[0052] It can be understood that in the present disclosure, the brake 3 to be tested is set on the shaft 11 of the base 1, and the force is applied to the brake 3 by the force applying member 21 to drive the brake 3 to slide on the shaft 11. The force measuring structure 4 detects the value of the force applied by the force applying member 21 on the brake 3, and then obtains the value of the friction between the brake 3 and the shaft 11. Subsequently, the obtained friction value is compared with the friction value in the working mode of the brake 3 to determine whether the brake 3 is qualified. When a brake 3 with compliant friction indicators is used, when performing the braking operation of the traction machine in the elevator, there will be no problem that the friction plate and the friction disc cannot be separated due to excessive friction.

[0053] The specific structure of this embodiment is described below:

[0054] See also Figure 1 As shown, the base 1 in this embodiment includes: a first base 12, on which the force-applying structure 2 is arranged; a second base 13, which is fixed on the test station, and on which the shaft 11 is detachably arranged. When in use, the first base 12 is installed on the second base 13 to realize the assembly of the entire base 1. The base 1 is divided into a first base 12 and a second base 13. The first base 12 is responsible for installing the force-applying structure 2, and the second base 13 is responsible for installing the brake 3. When the type of the brake 3 to be tested changes, the second base 13 can be replaced. This arrangement ensures that the same force-applying structure 2 and the force-measuring structure 4 can test different types of brakes 3 without replacement, thereby improving the applicability of the product and avoiding the problem of equipment replacement during testing.

[0055] As a variation, the first base 12 may be fixed on a testing station, and the second base 13 may be installed on the first base 12 .

[0056] As a variation, the base 1 can of course adopt an integrated structure to simplify the assembly steps in the scenario where a single type of product is to be tested.

[0057] See also Figure 1 and Figure 2As shown, the first base 12 in this embodiment is constructed as a common frame structure, which specifically includes: a frame 121, the frame 121 has a plurality of support beams, and the plurality of support beams are spliced ​​together to form a square frame, and a containing space is formed inside the square frame to facilitate the installation of the force-applying structure 2, the force-measuring structure 4, the distance-measuring device 5, etc. A first support plate 122 and a second support plate 123 spaced and arranged opposite to the first support plate 122 are also arranged on the frame 121, and one implementation method is: the first support plate 122 is arranged at the lower end of the frame 121 by screw locking or welding, and the second support plate 123 is arranged at the upper end of the frame 121 by screw locking or welding. The force-applying structure 2 in this embodiment is accommodated between the first support plate 122 and the second support plate 123 to prevent the force-applying structure 2 from leaking out and causing safety hazards during operation. As a modified implementation, corresponding support plate structures may also be installed on other sides of the rack 121 to construct the entire first base 12 into a box structure, thereby protecting the internal equipment of the rack 121 and providing rain and dustproof effects.

[0058] It is understandable that four feet 14 are also installed on the lower end surface of the first support plate 122 to ensure the stability of the support. As a modified embodiment, walking wheels can also be installed on the first support plate 122 to facilitate the movement of the brake detection device and facilitate the detection personnel to detect the brake at different locations.

[0059] See also Figure 2 As shown, the force-applying structure 2 in this embodiment includes: a lead screw 22, which is rotatably arranged on a first support plate 122, and two first mounting blocks 15 are arranged at intervals at the upper end surface of the first support plate 122. The first mounting blocks 15 are processed with threaded holes that can be screwed with the lead screw 22, and the two ends of the lead screw 22 are rotatably supported on the first mounting blocks 15. The force-applying structure 2 also includes: a power structure 23, which is arranged at the power input end of the lead screw 22 to drive the lead screw 22 to rotate. The power structure 23 in this embodiment is constructed as a handle structure, which is fixed at one end of the lead screw 22, and the rotation of the lead screw 22 is achieved by manual hand-cranking. As a modified embodiment, the structural form of the power structure 23 can also be driven by a motor, or other electric drive methods. The force-applying structure 2 also includes: a slider 24, which is slidably arranged on the lead screw 22. Manually shaking the handle structure drives the lead screw 22 to rotate, and then drives the slider 24 to make a linear reciprocating motion on the lead screw 22. The force member 21 in this embodiment is disposed on the slider 24, and can be detachably mounted by screw locking or the like to reduce the difficulty of assembling the whole device. As a modified embodiment, the force member 21 can also be integrally formed on the slider 24 to reduce the number of parts.

[0060] See also Figure 2As shown, the force-applying member 21 in this embodiment includes: a push rod 211, which is arranged on the slider 24. Specifically, the slider 24 in this embodiment includes: a sliding portion 241 arranged on the lead screw 22; and a connecting portion 242 detachably arranged on the sliding portion 241. The push rod 211 is arranged on the connecting portion 242. An axial hole is processed on the connecting portion 242. One end of the push rod 211 is fixed in the above-mentioned axial hole. The force-applying member 21 also includes a pressure head 212, which is detachably arranged at the end of the push rod 211 away from the slider 24. A through hole is provided in the axial direction of the pressure head 212. A threaded hole is provided in the axial direction of the push rod 211. The screw passes through the through hole and is locked in the threaded hole to fix the pressure head 212 on the push rod 211. When the handle structure rotates the lead screw 22, the slider 24 drives the pressure head 212 to abut against the brake 3. For the abutment position of the pressure head 212 on the brake 3, refer to Figure 7 As shown, combined with the above description of the structural form of the brake 3 in this embodiment, the pressure head 212 abuts against the housing of the brake 3 and is placed in the middle position of two axial holes suitable for installing pin shafts. The distance from the center of the two axial holes in the accompanying drawings to the center of the pressure head 212 is d.

[0061] See also Figure 1 and Figure 2 As shown, the force measuring structure 4 in this embodiment includes: a force sensor 41, which is arranged on the push rod 211 to obtain the pressure value applied by the pressure head 212 on the brake 3. The force sensor 41 in this embodiment is installed in a way that it is directly mounted on the push rod 211, and is located between the pressure head 212 and the adapter 242. When the pressure head 212 abuts against the brake 3, as the force is applied, the force sensor 41 will detect the value of the force.

[0062] In order to facilitate the inspection personnel to observe the friction force value detected by the force sensor 41, the force measuring structure 4 in this embodiment also includes: a digital dynamometer 42, which is arranged on the upper surface of the second support plate 123 and is connected to the force sensor 41 to display the pressure value. The second support plate 123 is arranged at the upper end of the brake detection device to facilitate the inspection personnel to observe. As a modified embodiment, the implementation position of the digital dynamometer 42 can also be on the side, front end or rear end of the brake detection device.

[0063] See also Figure 2As shown, the present embodiment also includes a distance measuring device 5, which is suitable for controlling the sliding stroke of the brake on the shaft 11. The distance measuring device 5 includes: a main scale 51, which is arranged on the upper surface of the second support plate 123 to facilitate the inspector to observe the distance measurement value; a vernier scale 52, which is slidably arranged on the main scale 51; a first adapter 53, one end of which is arranged on the vernier scale 52, and the other end is arranged on the slider 24. The specific first adapter 53 is constructed as an "L"-shaped sheet metal structure, and one end of which is specifically fixed on the adapter 242 on the slider 24. As a variation, the first adapter 53 can also be a "U"-shaped or other bent sheet metal. The distance measuring device 5 is used to facilitate the inspector to observe the moving distance of the brake on the shaft 11, and accurately define the starting moving position of the brake 3 on the shaft 11, so as to facilitate the comparison and judgment with the position movement in the use state, thereby improving the accuracy of the measurement.

[0064] See also Figure 5 As shown, in this embodiment, the second base 13 is mainly used to install the brake to be tested, and cooperate with the first base 12 to realize the detection of the brake thereon. The second base 13 includes: a third support plate 131, on which an axial hole is provided, and the axial hole and the shaft 11 are interference fit. When installing, the shaft 11 is installed in the axial hole by external force. The shaft 11 is fixed on the third support plate 131 in the following manner: the second base 13 includes a second adapter 132, which is a common flat plate structure, which is detachably arranged on the third support plate 131 in a screw-locking manner and covers the axial hole. The shaft 11 is arranged on the second adapter 132 through the axial hole, and a fixing hole is arranged on the axial end surface where the shaft 11 and the second adapter 132 cooperate, so as to facilitate the use of screws to lock the shaft 11 on the second adapter 132. When the shaft 11 needs to be replaced, the third support plate 131 with a new axial hole size can also be replaced.

[0065] Furthermore, the present embodiment further includes a fourth support plate 135 vertically disposed at the lower end of the third support plate 131, and the fourth support plate 135 is in contact with the ground to support the entire second base 13. A reinforcing plate 136 is further disposed at the connection between the third support plate 131 and the fourth support plate 135 to ensure the stability of the connection between the third support plate 131 and the fourth support plate 135.

[0066] In order to realize the detachable connection between the first base 12 and the second base 13, a first connecting member 124 is provided on the frame 121 in this embodiment. The first connecting member 124 is installed on the frame 121 near the pressure head of the first base 12. It is constructed as a common connecting plate structure. A clamping groove 1241 is provided on the first connecting member 124. The clamping groove 1241 is a common "U"-shaped groove structure with one end open. A second connecting member 133 is provided at the end of the shaft 11. The clamping groove 1241 can be clamped on the second connecting member 133. Specifically, the second connecting member 133 is in the shape of a roller. The middle of the wheel body is recessed inward to form a limiting groove 1331. When the clamping groove is clamped on the second connecting member 133, the limiting groove 1331 is limited to prevent it from detaching from the second connecting member 133. A mounting hole is provided at the middle position of the wheel body, which is screwed to the end position of the shaft 11.

[0067] Furthermore, the multiple slots 1241 in this embodiment are arranged at intervals on the first connecting member 124. Since the distances between the two pins of different brakes are different, the position of the second connecting member 133 on the corresponding third support plate 131 changes accordingly. The setting of the multiple slots 1241 can adapt to pin shaft distances of various sizes to facilitate the detection of various types of brakes, reduce the replacement of parts, and facilitate operation.

[0068] It can be understood that when the brake is mounted on the shaft 11, the distance between the second connecting member 133 and the third supporting plate 131 is greater than the maximum axial dimension of the brake to ensure that the brake can slide on the shaft.
