Description

Technical Field

[0001] The utility model relates to the field of traction wheels, in particular to a traction wheel groove wear detection device. Background Art

[0002] As the main component of the elevator traction system, the traction sheave plays an important role in ensuring the safe operation of the elevator. During long-term use, the wheel groove of the elevator traction sheave is in direct contact with the wire rope, which will inevitably cause surface wear. In addition, uneven tension in the same group of wire ropes or inconsistent wheel groove shape and depth of the traction sheave when leaving the factory will cause uneven wear of the traction sheave during use. When the wear of the traction sheave groove reaches a certain extent, it will affect the overall traction performance of the elevator, and it is easy to cause abnormal phenomena such as wire rope slippage and car vibration, which will directly lead to a decrease in riding comfort and even threaten the safety of passengers' lives and property.

[0003] After long-term use, the existing traction wheel requires workers to carry a detection device to detect wear thereof. A large amount of wear impurities will be present on the outer wall of the traction wheel after long-term use. Before detection, the workers are required to clean the outer wall of the traction wheel, which increases the detection burden of the workers. In addition, each time the detection is performed, the workers are required to hold the detection device and move it horizontally at the bottom of the traction wheel. This process wastes too much manpower and material resources and reduces the overall detection efficiency.

[0004] In summary, the above structure requires the staff to clean the outer wall of the traction wheel before testing, which increases the testing burden of the staff, wastes too much manpower and material resources during testing, and reduces the overall testing efficiency. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a traction wheel groove wear detection device to solve the technical problems that the staff is required to clean the outer wall of the traction wheel before detection, which increases the detection burden of the staff, wastes too much manpower and material resources during detection, and reduces the overall detection efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a traction wheel groove wear detection device, comprising a base, a driving assembly is arranged on one side of the base, a detection mechanism cooperating with the driving assembly is slidably arranged on the base, an elastic air bag is arranged on one side of the detection mechanism on the base, nozzles are provided on both sides of the elastic air bag on the base, slide grooves are symmetrically arranged on the top of the base, and a sliding plate is elastically arranged in the slide groove, and a fixed plate is arranged on one side of the top of the base.

[0007] By adopting the above technical scheme, the device is fixed to the outer wall of the traction wheel by the action of the compression spring, and then the detection mechanism is driven by the stepper motor to perform horizontal sliding detection at the bottom of the traction wheel body. At the same time, an elastic airbag is arranged on one side of the detection mechanism. When the stepper motor drives the elastic airbag to slide to one side, the gas in the elastic airbag will be discharged toward the nozzle. In this process, the bottom of the traction wheel body is cleaned during the detection process, which effectively reduces the cleaning burden of subsequent staff.

[0008] The utility model is further configured that the driving component is a stepping motor, and the stepping motor is used to drive the detection mechanism to slide on the base.

[0009] By adopting the above technical solution, it is convenient for the staff to control the sliding speed of the detection mechanism under the action of the stepping motor, thereby further improving the overall practicality of the device.

[0010] The utility model is further configured that a threaded rod is provided at the output end of the stepper motor, and a threaded sleeve is slidably provided on the outer wall of the threaded rod, and the top of the threaded sleeve is connected to the detection mechanism.

[0011] By adopting the above technical solution, the threaded rod at the output end will be driven to rotate under the action of the stepper motor. At this time, the threaded sleeve on the outer wall of the threaded rod will adjust the sliding direction according to the rotation direction of the threaded rod. As a result, the staff can adjust the detection work of the detection mechanism located at the overall traction wheel body according to actual conditions, thereby accelerating its overall detection efficiency.

[0012] The utility model is further configured that a compression spring is arranged in the slide groove, and the other end of the compression spring is connected to the sliding plate.

[0013] By adopting the above technical solution, when the staff pushes the sliding plate to one side, the compression spring is in a stretched state, which makes it easy to insert the traction wheel body between the sliding plate and the fixed plate. Then the staff releases the limiting work on the sliding plate. At this time, under the resetting action of the compression spring, the base is fixed to the outer wall of the traction wheel body.

[0014] The utility model is further configured that an air inlet is provided on one side of the elastic airbag, and an air inlet check valve and an air exhaust check valve are respectively provided in the air inlet and the nozzle.

[0015] By adopting the above technical scheme, during the process of the detection mechanism squeezing the elastic airbag, the air inlet check valve in the air inlet is closed, and the exhaust check valve at the nozzle is opened. At this time, the gas in the elastic airbag can be sprayed out through the nozzle to clean the bottom of the traction wheel body. At the same time, when the elastic airbag is subsequently reset by its own action, the air inlet check valve in the air inlet is opened, and the exhaust check valve at the nozzle is closed. At this time, the outside air is sucked into the elastic airbag, which effectively prevents the nozzle from being blocked due to the inhalation of impurities.

[0016] The utility model is further configured that the inner walls of the sliding plate and the fixed plate are both provided with protective covers.

[0017] By adopting the above technical solution, the protective cover can prevent the sliding plate and the fixing plate from directly contacting the outer wall of the traction sheave body, thereby effectively preventing the traction sheave body from being worn during the clamping and limiting process.

[0018] The utility model is further configured such that the elastic airbag is located on the outer wall of the threaded rod and is in a non-contact state with the threaded rod.

[0019] By adopting the above technical solution, the outer wall of the threaded rod can be prevented from damaging the inner wall of the elastic airbag during the rotation of the threaded rod.

[0020] The utility model is further configured such that the nozzles are located on the top of the base and are inclined relative to each other.

[0021] By adopting the above technical solution, the inclined setting makes it easy to increase the spraying area of ​​the nozzle, and further improves the cleaning effect of the nozzle on the bottom of the traction wheel body.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a sliding plate which is slidably arranged on a base, and the sliding plate is pressed toward one side so that the compression spring is in a stretched state, and then the sliding plate is clamped into the outer wall of the traction wheel body, and the device is fixed to the outer wall of the traction wheel body by the action of the compression spring, and then the detection mechanism is driven by the action of the stepping motor to perform horizontal sliding detection on the bottom of the traction wheel body, which saves a lot of manpower and material resources and speeds up the overall detection efficiency. At the same time, an elastic airbag is arranged on one side of the detection mechanism, and the gas in the elastic airbag is discharged toward the nozzle when the stepping motor drives the elastic airbag to slide toward one side, and in this process, the bottom of the traction wheel body is cleaned during the detection process, which effectively reduces the cleaning burden of subsequent staff.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A traction sheave groove wear detection device, such as Figure 1-Figure 4 As shown, it includes a base 1, a traction wheel body 4, a sliding mechanism, a detection mechanism 10 and a reset mechanism. A slide groove 5 is symmetrically arranged on the top of the base 1, and a compression spring 8 is arranged in the slide groove 5, and the other end of the compression spring 8 is connected to the sliding plate 2. When the staff moves the sliding plate 2 to one side, the compression spring 8 is in a stretched state, which is convenient for the traction wheel body 4 to be stuck between the sliding plate 2 and the fixed plate 7. Then the staff releases the limiting work on the sliding plate 2. At this time, under the reset action of the compression spring 8, the base 1 is fixed to the outer wall of the traction wheel body 4. At the same time, a stepping motor 3 is arranged on one side of the base 1, and the sliding on the base 1 A detection mechanism 10 is provided to cooperate with the stepper motor 3. The stepper motor 3 drives the detection mechanism 10 to perform horizontal sliding detection at the bottom of the traction wheel body 4. In this process, a lot of manpower and material resources are saved, and the overall detection efficiency is accelerated. An elastic airbag 9 is provided on one side of the detection mechanism 10 on the base 1, and nozzles 6 are provided on both sides of the elastic airbag 9 on the base 1. In the process of the stepper motor 3 driving the elastic airbag 9 to slide to one side, the gas in the elastic airbag 9 will be discharged to the nozzle 6. In this process, the bottom of the traction wheel body 4 is cleaned during the detection process, which effectively reduces the cleaning burden of subsequent staff.

[0033] See also Figure 4 An air inlet is provided on one side of the elastic airbag 9, and an air inlet check valve and an exhaust check valve are respectively provided in the air inlet and the nozzle 6. When the detection mechanism 10 squeezes the elastic airbag 9, the air inlet check valve in the air inlet is closed, and the exhaust check valve at the nozzle 6 is opened. At this time, the gas in the elastic airbag 9 can be sprayed out through the nozzle 6 to clean the bottom of the traction wheel body 4. At the same time, when the elastic airbag 9 is reset by its own action, the air inlet check valve in the air inlet is opened, and the exhaust check valve at the nozzle 6 is closed. At this time, the outside air is sucked into the elastic airbag 9, which effectively prevents the nozzle from being blocked due to the inhalation of impurities.

[0034] See also Figure 3 A protective cover is provided on the inner walls of the sliding plate 2 and the fixed plate 7. The protective cover can prevent the sliding plate 2 and the fixed plate 7 from directly contacting the outer wall of the traction wheel body 4, thereby effectively preventing the traction wheel body 4 from being worn during the clamping and limiting process.

[0035] Embodiment 2

[0036] like Figure 1 A traction wheel groove wear detection device shown in the figure has an overall structure similar to that of the first embodiment, wherein a threaded rod is provided at the output end of the stepper motor 3, and a threaded sleeve is slidably provided on the outer wall of the threaded rod, and the top of the threaded sleeve is connected to the detection mechanism 10. Under the action of the stepper motor 3, the threaded rod at the output end is driven to rotate. At this time, the threaded sleeve on the outer wall of the threaded rod adjusts the sliding direction according to the rotation direction of the threaded rod, thereby enabling the staff to adjust the detection work of the detection mechanism located at the entire traction wheel body according to actual conditions, thereby accelerating its overall detection efficiency.

[0037] The working principle of the utility model is as follows: when in use, the sliding plate 2 is pushed to one side so that the sliding plate 2 squeezes the compression spring 8 on the base 1. At this time, the compression spring 8 is in a stretched state. At the same time, the staff clamps the sliding plate 2 and the fixed plate 7 on the outer wall of the traction wheel body 4. Then, under the reset action of the compression spring 8, the sliding plate 2 is driven to reset and slide, so that the base 1 is limited to the outer wall of the traction wheel body 4 as a whole. Then, by starting the stepper motor 3, the detection mechanism 10 is made to slide under the action of the stepper motor 3 to detect the wear of the traction wheel body 4. At the same time, an elastic air bag 9 is provided on one side of the detection mechanism 10 on the base 1. In the process of detecting the traction wheel body 4 by sliding the detection mechanism 10, the detection mechanism 10 will also squeeze the elastic air bag 9 on one side. In this process, the gas in the elastic air bag 9 will be discharged through the nozzles 6 on both sides, thereby realizing the cleaning of the bottom of the traction wheel body 4, effectively reducing the cleaning burden of subsequent staff.

[0038] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
