Description

Technical Field

[0001] The utility model belongs to the technical field of elevator detection, and in particular relates to an elevator braking detection device. Background Art

[0002] In the daily operation and maintenance of elevators, it is crucial to accurately measure the elevator's running speed, running distance, braking distance and other data. These data provide a key basis for evaluating the elevator's operating status and ensuring its safety and performance. The traditional method of measuring the speed of elevator wire ropes usually relies on handheld instruments, which measure the speed by contacting the wire rope. The staff needs to manually press the instrument to generate sufficient friction between the front speed measuring wheel and the wire rope so that the two rotate synchronously.

[0003] However, this traditional measurement method has several significant problems. First, the device is large and inconvenient to carry. Due to different pressures applied by different workers, insufficient pressure may lead to insufficient friction, causing slippage between the speed measuring wheel and the wire rope. This slippage will directly lead to errors in the measurement results, affecting the accurate judgment of the elevator operation status.

[0004] Secondly, the existing elevator braking capacity testers have different specifications, which means that the existing fixtures can only test wire ropes of specific specifications and lack versatility. When a tester of a different specification is needed, the fixture needs to be replaced or adjusted, which not only increases the complexity of the operation, but also may affect the accuracy and efficiency of the measurement.

[0005] Therefore, in response to the above problems, it is particularly urgent to improve and innovate the measurement methods and fixing devices of elevator wire rope speed and other data. Utility Model Content

[0006] The utility model provides an elevator brake detection device, aiming to solve the problems that the device is large in size and inconvenient to carry, which limits its rapid movement and application between different elevators; secondly, due to the different pressing strengths of the staff, it may cause insufficient friction and slippage between the speed measuring wheel and the wire rope, thereby introducing measurement errors and affecting the accurate assessment of the elevator status; in addition, the existing elevator braking capacity testers have different specifications, and the fixing devices are usually only applicable to wire ropes of specific specifications, lacking versatility.

[0007] The utility model is implemented as follows: an elevator brake detection device comprises a box body; a detection mechanism arranged on the outside of the box body; wherein the detection mechanism comprises: a first connecting block arranged on the outside of the box body; a speed measuring wheel rotating on the outside of the first connecting block; a second connecting block arranged beside the first connecting block; a clamping wheel rotating on the outside of the second connecting block, the clamping wheel slidingly cooperates with the box body; a rack arranged on the inside of the box body, the second connecting block extending to one side of the box body and connected to the rack; a gear arranged on the rack, the gear meshing with the rack; a screwing handle arranged beside the second connecting block, the screwing handle extending to one side of the box body and fixedly connected to the end key of the gear.

[0008] Preferably, sliding grooves are provided on both sides of the upper surface of the box body, and a same protective cover is slidably fitted between the two sliding grooves.

[0009] Preferably, both side outer walls of the box body are provided with wedge blocks, and connecting ropes are provided on the outer sides of the two wedge blocks, and the same Japanese-shaped buckle is connected between the two connecting ropes.

[0010] Preferably, the outer surfaces of the speed measuring wheel and the clamping wheel are sprayed with an anti-slip layer.

[0011] Preferably, a rubber pad is provided on a side of the box body away from the protective cover, and the rubber pad is provided with anti-slip patterns.

[0012] Preferably, a torque sensor is arranged in the tachometer wheel, and a display screen electrically connected to the tachometer wheel is arranged on the box.

[0013] Preferably, a limiting channel for sliding of the second connecting block is opened on the outer side of the box body.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] First: This device has high adaptability and flexibility. By dynamically adjusting the position of the clamping wheel, it can adapt to elevator wire ropes of different thicknesses with the speed measuring wheel. By adjusting the position between the clamping wheel and the speed measuring wheel, not only the contact area between the two and the elevator wire rope is increased, but also the friction coefficient is optimized, which further ensures the measurement accuracy and reduces the error caused by slipping. The torque sensor integrated inside the speed measuring wheel can sense and measure the speed and torque changes of the elevator wire rope in real time. This real-time monitoring function ensures the accuracy and timeliness of the data. Through the display screen on the box, the staff can intuitively see the real-time data during the elevator braking process. This intuitive display not only makes it easier for the staff to understand and analyze the data, but also improves work efficiency and safety.

[0016] Second: The device is small in size and easy for staff to carry around. It can be easily put into a tool bag or backpack. This portability allows inspectors to move quickly between different elevators, improving work efficiency. The protective cover can effectively protect the internal components of the device from external environmental damage such as dust and moisture, thereby extending the service life of the device. The adjustable connecting rope enables the device to adapt to various working environments and operating scenarios, enhancing its flexibility and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The utility model provides an elevator brake detection device, such as Figure 1-6 As shown, it includes a box body 1; a detection mechanism arranged on the outside of the box body 1; wherein the detection mechanism includes: a first connecting block 201 arranged on the outside of the box body 1; a speed measuring wheel 202 rotating on the outside of the first connecting block 201; a second connecting block 203 arranged beside the first connecting block 201; a clamping wheel 204 rotating on the outside of the second connecting block 203, and the clamping wheel 204 slidingly cooperates with the box body 1; a rack 205 arranged on the inside of the box body 1, and the second connecting block 203 extends to one side of the box body 1 and is connected to the rack 205; a gear 206 arranged on the rack 205, and the gear 206 is meshed with the rack 205; a screwing handle 207 arranged beside the second connecting block 203, and the screwing handle 207 extends to one side of the box body 1 and is fixedly connected to the end key of the gear 206.

[0027] It should be noted that the device is large and inconvenient to carry, which limits its rapid movement and application between different elevators. Secondly, due to the different pressing strengths of the staff, it may cause insufficient friction and slippage between the speed wheel 202 and the wire rope, thereby introducing measurement errors and affecting the accurate assessment of the elevator status. In addition, the existing elevator braking capacity testers have different specifications, and the fixing devices are usually only suitable for wire ropes of specific specifications, lacking versatility. The core features of this solution include the ability to dynamically adjust the clamping wheel 204 and the speed wheel 202 to adapt to elevator wire ropes of different thicknesses, by optimizing the friction coefficient and contact area. The device ensures measurement accuracy and significantly reduces errors caused by slippage. In addition, the torque sensor integrated in the tachometer wheel 202 can sense and measure the rotation speed and torque changes of the elevator wire rope in real time, providing accurate and timely data feedback for the staff; the device is small in size and easy for the staff to carry, thereby improving the work efficiency of moving between different elevators. The protective cover 4 design effectively protects the internal components from the external environment and extends the service life of the device. At the same time, the adjustable connecting rope 6 enables the device to adapt to various working environments and operating scenarios, enhancing its flexibility and adaptability.

[0028] Specifically, in this embodiment, the scheme mainly includes a box body 1 and a detection mechanism arranged on the outside of the box body 1; when the elevator brake is in working state, that is, the elevator stops moving, the elevator brake detection mechanism starts to play its role; first, the staff places the elevator wire rope on the outside of the speed measuring wheel 202 to ensure that the wire rope has good contact with the speed measuring wheel 202; then, the staff rotates the screw handle 207; since the screw handle 207 is fixedly connected to the end key of the gear 206, the rotation of the screw handle 207 will drive the gear 206 to rotate simultaneously. The gear 206 meshes with the rack 205, so the rotation of the gear 206 drives the rack 205 to move linearly; since the second connecting block 203 is connected to the rack 205, the linear movement of the rack 205 drives the second connecting block 203 to move synchronously; as the second connecting block 203 moves, the clamping wheel 204 slides along the box body 1 until it fits to the other side of the wire rope, thereby limiting the moving space of the wire rope. This design enables the clamping wheel 204 to adapt to elevator wire ropes of different thicknesses and perform effective clamping;

[0029] When the elevator brake is applied, the wire rope will contact the tachometer wheel 202 and cause it to rotate. A torque sensor is provided inside the tachometer wheel 202 to measure the rotation speed of the tachometer wheel 202. The torque sensor can accurately sense the change in rotation speed and transmit the data to the display screen 9 provided on the box body 1, thereby indirectly reflecting the braking effect of the elevator brake.

[0030] In a further preferred embodiment of the present invention, Figure 4 As shown, slide grooves 3 are provided on both sides of the upper surface of the box body 1 , and a protective cover 4 is slidably fitted between the two slide grooves 3 .

[0031] In this embodiment, the protective cover 4 can slide to the top of the box body 1 to completely cover the detection display screen 9, thereby playing a protective role. When the device needs to be used, the staff can slide the protective cover 4 to expose the detection display screen 9 for easy operation and monitoring.

[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, wedge blocks 5 are provided on both side outer walls of the box body 1, connecting ropes 6 are provided on the outer sides of the two wedge blocks 5, and the same Japanese-shaped buckle 7 is connected between the two connecting ropes 6.

[0033] In this embodiment, the connecting rope 6 is an important component of the elevator brake detection mechanism, and the need for carrying is taken into consideration. When the length of the connecting rope 6 needs to be adjusted, the staff only needs to unfasten the Japanese buckle 7 and then re-fix it to the desired position, thereby conveniently adjusting the wearing length of the connecting rope 6 to adapt to different usage scenarios and individual needs.

[0034] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the outer surfaces of the speed measuring wheel 202 and the clamping wheel 204 are sprayed with an anti-slip layer.

[0035] In this embodiment, the anti-skid layer can significantly increase the friction between the speed measuring wheel 202 and the clamping wheel 204 and the elevator wire rope, ensuring that the wire rope can firmly fit on the wheel during braking to avoid slipping or sliding; due to the presence of the anti-skid layer, the speed measuring wheel 202 and the clamping wheel 204 can maintain a more stable operating state when contacting the wire rope, thereby improving the accuracy and reliability of braking detection: the anti-skid layer can also reduce the wear between the wheel and the wire rope to a certain extent, extending the service life of the speed measuring wheel 202 and the clamping wheel 204.

[0036] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a rubber pad 8 is provided on the side of the box body 1 away from the protective cover 4, and the rubber pad 8 is provided with anti-slip patterns.

[0037] In this embodiment, when the box body 1 is placed on an uneven or smooth surface, these anti-skid patterns can effectively prevent the box body 1 from sliding or moving, thereby ensuring that the elevator brake detection device remains stable during operation.

[0038] In a further preferred embodiment of the present invention, Figure 4 As shown, a torque sensor is arranged inside the speed measuring wheel 202, and a display screen 9 electrically connected to the speed measuring wheel 202 is arranged on the box body 1.

[0039] In this embodiment, the torque sensor (T22 / 0.5NM) is a device that can measure the torque exerted on a rotating object, and can sense in real time the torque changes generated by the tachometer wheel 202 when it contacts the elevator wire rope; by embedding the torque sensor inside the tachometer wheel 202, the real-time force of the wire rope on the tachometer wheel 202 can be directly obtained, thereby more accurately measuring the rotation speed of the wire rope; the torque sensor converts the sensed torque signal into an electrical signal and transmits it to the display screen 9 on the box 1 for display; the staff can observe the data on the display screen 9 to understand in real time the wire rope rotation speed and torque changes during the elevator braking process.

[0040] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a limiting channel 10 for the second connecting block 203 to slide is opened on the outer side of the box body 1.

[0041] In this embodiment, the limiting channel 10 can ensure the stability and accuracy of the second connecting block 203 during the sliding process, thereby preventing it from shaking or misalignment.

[0042] Working principle: When the device needs to be used, the staff can slide the protective cover 4 to expose the display screen 9 for easy operation and monitoring; when the elevator brake is in working state, that is, the elevator stops moving, the elevator brake detection mechanism begins to play its role; first, the staff places the elevator wire rope on the outside of the speed measuring wheel 202 to ensure that the wire rope has good contact with the speed measuring wheel 202; then, the staff turns the screw handle 207; since the screw handle 207 is fixedly connected to the end key of the gear 206, the rotation of the screw handle 207 will drive the gear 206 rotates synchronously, and the gear 206 is meshed with the rack 205, so the rotation of the gear 206 drives the rack 205 to move linearly; since the second connecting block 203 is connected to the rack 205, the linear movement of the rack 205 drives the second connecting block 203 to move synchronously; as the second connecting block 203 moves, the clamping wheel 204 slides along the box body 1 until it fits to the other side of the wire rope, thereby limiting the moving space of the wire rope. This design enables the clamping wheel 204 to adapt to elevator wire ropes of different thicknesses and perform effective clamping;

[0043] When the elevator brake is applied, the wire rope will contact the tachometer wheel 202 and cause it to rotate. A torque sensor is provided inside the tachometer wheel 202. The torque sensor is a device that can measure the torque exerted on a rotating object and can sense in real time the torque changes generated by the tachometer wheel 202 when it contacts the elevator wire rope. By integrating the torque sensor into the tachometer wheel 202, the real-time force exerted by the wire rope on the tachometer wheel 202 can be directly obtained, thereby more accurately measuring the rotation speed of the wire rope. The torque sensor converts the sensed torque signal into an electrical signal and transmits it to the display screen 9 on the box body 1 for display. The staff can observe the data on the display screen 9 to understand in real time the rotation speed and torque changes of the wire rope during the elevator braking process.
