Description
Technical Field
[0001] This invention relates to the field of vehicle reducer technology, and in particular to an auxiliary detection device and method for detecting the distance between the openings of two brake rails in a vehicle reducer. Background Technology
[0002] A vehicle speed reducer is a device that relies on brake rails to clamp the sides of the vehicle (specifically, a railway train) wheels and achieves speed reduction through friction. It is the main speed control tool for mechanized and automated hump yards.
[0003] After a period of use, the gap between the two brake rails of a vehicle reducer will widen due to prolonged friction between the two brake rails and the wheels, resulting in a decrease in the braking force exerted by the reducer on the wheels. To ensure a constant braking force exerted by the vehicle reducer on the vehicle, the gap between the two brake rails needs to be adjusted periodically. The prerequisite for this adjustment is to detect and obtain the gap size between the two brake rails (i.e., the gap distance, which is the minimum distance between the arc surfaces of the rail heads of the two brake rails, and is the straight-line distance between the two brake rails located on both sides of the base rail).
[0004] However, the tools commonly used to measure the opening size (i.e., opening distance) between brake rails are general measuring tools (such as calipers). Due to the irregular size of the brake rail head end face, the measurement of the minimum distance between two brake rails generally has a large error and low accuracy.
[0005] Therefore, there is an urgent need to develop a technology that can solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to address the technical deficiencies of existing technologies by providing an auxiliary detection device and method for detecting the distance between the openings of the two brake rails of a vehicle decelerator.
[0007] To this end, the present invention provides an auxiliary detection device for the distance between the openings of two brake rails of a vehicle reducer, which includes a traveling device, a testing device and a connecting plate; The traveling device can be moved back and forth and placed on top of the two brake rails to be tested; The two brake rails include a left brake rail and a right brake rail; the basic rail is located below the gap between the left brake rail and the right brake rail. The test device is placed on top of the base rail and positioned between the left and right brake rails; The top of the testing device is connected to the front of the walking device via the connecting plate; The testing device includes: a support base, an intermediate plate, a first test plate, a second test plate, a linear guide rail, a spring, a guide column, and a sensor; A vertically distributed intermediate plate is set at the top rear end of the support base; A horizontally distributed linear guide rail is provided at the top front end of the support base; The linear guide rail has a first slider and a second slider that are spaced apart to the left and right. A first test plate is set on the top of the first slider; A second test plate is provided at the top of the second slider; The upper part of the first test plate and the second test plate on opposite sides is connected to a horizontally distributed guide post. Two guide posts are connected to the two ends of the spring, respectively; The second test board has horizontally distributed sensors on the side facing the first test board.
[0008] As can be seen from the technical solution provided by the present invention above, compared with the prior art, the present invention provides an auxiliary detection device and detection method for the opening distance between the two brake rails of a vehicle reducer. The design is scientific and can assist the staff to conveniently and reliably measure the opening size (i.e., opening distance) between the brake rails, improve the accuracy of the measurement data, and has significant practical significance.
[0009] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The measurement data results of this invention have high accuracy and avoid interference from human measurement factors.
[0010] 2. The measurement results of this invention can provide a basis for adjusting the opening distance between brake rails.
[0011] 3. This invention can be operated by one person without the need for two people to cooperate, which significantly saves manpower and reduces labor costs. Attached Figure Description

[0017] The technical solution of the present invention will be further described below through specific embodiments. Details not specified in the embodiments are all conventional technologies in the industry.
[0018] Example 1 See Figures 1 to 16 The present invention provides an auxiliary detection device for the distance between the openings of two brake rails of a vehicle reducer, comprising a traveling device 1, a testing device 2 and a connecting plate 3; The walking device 1 can be moved back and forth and placed on top of the two brake rails to be tested; The two brake rails include a left brake rail 100 and a right brake rail 200; a base rail 300 (for passing the wheels of the train) is located below the gap between the left brake rail 100 and the right brake rail 200. The test device 2 is placed on top of the basic rail 300 and is located between the left brake rail 100 and the right brake rail 200; The top of the testing device 2 is connected to the front of the walking device 1 via the connecting plate 3; It should be noted that the testing device 2 is used to provide specific data for calculating the opening distance between the two brake rails, left brake rail 100 and right brake rail 200.
[0019] In this invention, specifically, the left brake rail 100 and the right brake rail 200 are axially symmetrically distributed; In this invention, see Figure 3 , Figure 6 and Figure 7 As shown, the walking device 1 includes: a top cover 102, rollers 103 (also known as wheel sets) and handles 104; The upper cover 102 includes an upper cover top plate 1021 and an upper cover side plate 1022; At the bottom left and right ends of the horizontally distributed top cover plate 1021, a vertically distributed side cover plate 1022 is respectively provided. At the bottom front and rear ends of each top cover side panel 1022, a roller 103 is pivotally connected (i.e., rotatably connected); The bottom of roller 103 contacts the top of brake rail; In practice, the bottom of the roller 103 contacts the bottom surface of the groove on the top of the brake rail; In practice, a handle 104 is provided on each of the two opposite sides of the top cover side panels 1022. Furthermore, the two handles 104 are symmetrically distributed from left to right; Furthermore, the front and rear ends of the handle 104 are respectively connected to the upper cover side plate 1022 by a bolt.
[0020] In specific implementation, the two rollers 103 located at the bottom of the left upper cover side plate 1022 are symmetrically distributed with the two rollers 103 located at the bottom of the right upper cover side plate 1022. In this invention, the testing device 2 includes: a support base 201, an intermediate plate 202, a first testing plate 2031, a second testing plate 2032, a limiting frame 204, a linear guide rail 205, a spring 206, a guide post 207, a partition 208, and a sensor 209. A vertically distributed intermediate plate 202 is provided at the top rear end of the support base 201; A horizontally distributed linear guide rail 205 is provided at the top front end of the support base 201; The linear guide 205 has a first slider 2051 and a second slider 2052 that are spaced apart from each other on the left and right sides. It should be noted that the two sliders on the linear guide (e.g., the first slider 2051 and the second slider 2052) can slide laterally left and right along the guide body. Linear guides are conventional mechanical components with mature existing technology and are well-known technology, so they will not be described in detail here.
[0021] The top of the first slider 2051 is provided with a first test plate 2031; The top of the second slider 2052 is provided with a second test plate 2032; The upper part of the first test plate 2031 and the second test plate 2032 on opposite sides is connected to a horizontally distributed guide post 207. Two guide posts 207 are respectively connected to the two ends of the spring 206; The second test board 2032 has horizontally distributed sensors 209 on the side facing the first test board 2031.
[0022] In a specific implementation, the two guide posts 207 are respectively inserted into the inner sides of the two ends of the spring 206; It should be noted that the two guide posts 207 are respectively passed through the two inner ends of the spring 206, the spring 206 is not fixedly connected to the guide posts, and the spring 206 can freely extend and retract. The spring 206 is a compression spring, and the two ends of the spring 206 are in contact with the test plates on both sides (the first test plate 2031 and the second test plate 2032) respectively.
[0023] It should be noted that for the present invention, the spring 206 is placed at the position between the first test plate 2031 and the second test plate 2032, and guided by the two guide posts 207.
[0024] In a specific implementation, the normal cross-sectional shape of the support base 201 is an inverted "U" shape.
[0025] In a specific implementation, the support base 201 is provided with a stock rail receiving groove 2011 with a downward opening; The top of the stock rail 300 is located in the stock rail receiving groove 2011.
[0026] In a specific implementation, the intermediate plate 202 is welded to the support base 201.
[0027] In a specific implementation, the guide rail body 2053 of the linear guide rail 205 is fixed to the top of the support base 201 by a plurality of (for example, three) bolts.
[0028] In a specific implementation, one limit frame 204 is respectively disposed on each of the left and right sides of the support base 201 at a position corresponding to the two ends of the linear guide rail 205; One end of each of the two limit frames 204 is respectively hinged (i.e., connected in a relatively rotatable manner) to the left and right sides of the support base 201 Further, a support base threaded hole 2012 is disposed on each of the left and right sides of the support base 201; Each limit frame 204 includes one limit plate 2041 and one limit post 2042; the middle part of the limit plate 2041 is connected to the limit post 2042; The external thread provided on each limit post 2042 is in threaded connection with the support base threaded hole 2012 on the support base 201, so as to realize the hinged connection between the limit frame 204 and the support base 201; It should be noted that, refer to Figure 15 , Figure 16As shown, the limiting plate 2041 is elongated and fixed together with the limiting post 2042. The limiting post 2042 has external threads, and the support seat threaded hole 2012 on the support seat 201 has internal threads. The limiting post 2042 is threadedly connected to the support seat 201. The limiting post 2042 is screwed into the support seat 201. When the limiting plate 2041 contacts the opposite side of the test plates (first test plate 2031 and second test plate 2032) on the two sliders (e.g., the first slider 2051 and the second slider 2052), it limits the sliders and the test plates on the sliders. When the limiting plate 2041 does not contact the opposite side of the test plates (first test plate 2031 and second test plate 2032) on the two sliders, it means that the limiting frame does not limit the sliders and the test plates on the sliders, that is, it is released.
[0029] It should be noted that, in this invention, since the limiting frame 204 is hinged to the support base 201 via the limiting post 2042, the exposed limiting plate 2041 can be rotated clockwise or counterclockwise by hand or with the aid of other tools, thereby changing the distribution and installation angle of the limiting plate 2041 on the support base 201. For example, it could be... Figure 4 The vertical horizontal distribution shown can also be achieved by rotating the object to a vertical distribution.
[0030] Furthermore, see Figure 13 , Figure 15 As shown, when the limiting plate 2041 is in a vertically distributed state (achieved by rotating the limiting plate), the top height of the limiting plate 2041 is greater than the bottom height of the first slider 2051 and the second slider 2052 and is also greater than the bottom height of the first test plate 2031 and the second test plate 2032. The opposite sides of the first test plate 2031 and the second test plate 2032 on the first slider 2051 and the second slider 2052 respectively abut (closely contact) with the opposite side (inner side) of the two limiting plates 2041. Therefore, at this time, the two limiting plates 2041 can limit the first slider 2051 and the second slider 2052 located inside the two limiting plates 2041, as well as the first test plate 2031 and the second test plate 2032 on the two sliders (to counteract the outward pushing force exerted by the two ends of the spring 206 on the first test plate 2031 and the second test plate 2032, as well as the first slider 2051 and the second slider 2052, i.e., to counteract the elastic pushing force provided by the spring 206 that causes the first test plate 2031 and the second test plate 2032 to move in opposite directions). In other words, at this time, the two limiting plates 2041 are in a limited and locked state.
[0031] Furthermore, see Figure 16 As shown, when the limiting plate 2041 is in a longitudinally horizontal distribution state (achieved by rotating the limiting plate, such as...), Figure 4As shown), the top height of the limiting plate 2041 is less than the bottom height of the first slider 2051 and the second slider 2052 (and also less than the bottom height of the first test plate 2031 and the second test plate 2032). At this time, the two limiting plates 2041 no longer limit the first slider 2051 and the second slider 2052, as well as the first test plate 2031 and the second test plate 2032 on the two sliders. The two limiting plates 2041 are no longer in the limiting and locked state, but in the released state.
[0032] It should be noted that the limiting post 2042 of the limiting frame 204 has external threads, which can be screwed into the threaded holes 2012 of the support seat on both sides of the support seat 201, thereby allowing the limiting plate 2041 to rotate. The two limiting plates 2041 can limit the two sliders on the linear guide rail 205 and the first test plate 2031 and the second test plate 2032 on the two sliders.
[0033] In practice, the bottom of the first test board 2031 is fixedly connected to the first slider 2051 by multiple (e.g., four) bolts; The bottom of the second test plate 2032 is fixedly connected to the second slider 2052 by multiple (e.g., four) bolts; In practice, the two guide pillars 207 are symmetrically distributed from left to right; In specific implementation, the upper part of the first test plate 2031 and the second test plate 2032 on the opposite side are respectively provided with threaded holes 20311 and 20321 through the first test plate. The threaded hole 20311 of the first test plate and the threaded hole 20321 of the second test plate are respectively threadedly fixed to the external thread of one end of a guide post 207.
[0034] In specific implementation, two longitudinally distributed lifting columns 4 are provided on the upper front side of the intermediate plate 202; It should be noted that, in this invention, the testing device 2 can be lifted by the lifting column 4, so that the testing device 2 can leave the basic track 300.
[0035] In specific implementation, the lower part of the second test board 2032 facing the first test board 2031 is provided with horizontally distributed partitions 208; A sensor 209 is installed on the top of the partition 208; The right side of sensor 209 is attached to the left side of the second vertical plate 20320 of the second test plate 2032; It should be noted that sensor 209 is used to measure the distance D between its left side and the right side of the first test plate 2031 (specifically, the right side of the first vertical plate 20310 on the upper part of the first test plate 2031).
[0036] Furthermore, the top height of sensor 209 is lower than the bottom height of spring 206 and guide post 207.
[0037] It should be noted that, in specific implementation, sensor 209 is a well-established and known ranging sensor, such as a laser ranging sensor, ultrasonic ranging sensor, or infrared ranging sensor, which are conventional devices and will not be described in detail here. In this invention, sensor 209 can be a laser sensor of model EG-1000N manufactured by Shenzhen Xinzhun Technology Co., Ltd., which can measure the distance to the test board (right side of the first test board 2031).
[0038] In this invention, specifically, the top of the testing device 2 is connected to the front side of the walking device 1 via the connecting plate 3, and the specific structural design is as follows: The middle plate 202 at the top of the test device 2 is connected to the lower part of the connecting plate 3 through two lifting columns 4; The upper part of the connecting plate 3 is connected to the front side of the top plate 1021 of the upper cover 102 by two bolts; Furthermore, the intermediate plate 202 at the top of the testing device 2 is connected to the lower part of the connecting plate 3 via two lifting columns 4. The specific structural design is as follows: The top of the intermediate plate 202 has an upward-opening connecting plate embedding groove 2021; The lower part of the connecting plate 3 is inserted into the connecting plate embedding groove 2021; Two longitudinally distributed lifting column insertion holes 2022 are provided on the front side of the intermediate plate 202; The rear ends of the two lifting column insertion holes 2022 are directly connected to the inner cavity of the connecting plate embedding groove 2021; At the lower part of the connecting plate 3, a lifting rod docking hole 301 is longitudinally provided at the position corresponding to each lifting column insertion hole 2022; After passing through the lifting column insertion hole 2022 from front to back, the lifting column 4 is inserted into the lifting rod docking hole 301 located at the lower part of the connecting plate 3 in the connecting plate embedding groove 2021.
[0039] Furthermore, the upper part of the connecting plate 3 is connected to the front side of the top plate 1021 of the upper cover 102 via two connecting bolts. The specific structural design is as follows: See Figure 6 , Figure 8 As shown, the upper cover 102 includes an upper cover top plate 1021 with two upper cover top plate threaded holes 10211 in the middle of the front side; A connecting plate through hole 302 is provided on the upper part of the connecting plate 3 at a position corresponding to each threaded hole 10211 on the top plate of the cover; After the connecting bolt passes through the connecting plate through hole 302 on the connecting plate 3 from front to back, it is threadedly fixed to the upper cover top plate threaded hole 10211 on the upper cover top plate 1021.
[0040] Example 2 Based on the auxiliary detection device for the distance between the openings of the two brake rails of a vehicle reducer provided by the present invention, the present invention also provides a method for detecting the distance between the openings of the two brake rails of a vehicle reducer based on the auxiliary detection device for the distance between the openings of the two brake rails of a vehicle reducer, characterized by comprising the following steps: Step S1: Lift the test device 2 upward (by lifting column 4 set on connecting plate 3), and move the walking device 1 longitudinally on left brake rail 100 and right brake rail 200 until it stops at the position where the opening distance needs to be measured on left brake rail 100 and right brake rail 200. At this time, the test device 2 is located at the top of basic rail 300. In specific implementation, in step S1, the two limiting plates 2041 in the two limiting frames 204 of the testing device 2 are respectively in contact with the opposite sides of the first test plate 2031 and the second test plate 2032 on the first slider 2051 and the second slider 2052, i.e., in a limiting and locking state.
[0041] In specific implementation, in step S1, the top of the basic rail 300 is located in the basic rail receiving groove 2011 of the support seat 201 of the test device 2.
[0042] Step S2: Release the two limiting frames 204 in the testing device 2 so that the opposite side of the two limiting plates 2041 in the two limiting frames 204 no longer abuts against the opposite side of the first test plate 2031 and the second test plate 2032 on the first slider 2051 and the second slider 2052. Under the elastic force of the spring 206, the first test plate 2031 and the second test plate 2032 gradually approach the left brake rail 100 and the right brake rail 200, and the opposite side of the first test plate 2031 and the second test plate 2032 respectively fits against the brake rail surface 400 (i.e., the rail head arc surface) on the opposite side of the left brake rail 100 and the right brake rail 200. Step S3: Measure the distance D between the left side of the sensor 209 on the second test board 2032 and the right side of the first test board 2031 (specifically, the right side of the first vertical plate 20310 on the upper part of the first test board 2031) using the sensor 209 on the second test board 2032. Step S4: According to the preset formula for calculating the opening distance of the brake rails, obtain the opening distance L of the left brake rail 100 and the right brake rail 200. In specific implementation, in step S4, the preset formula for calculating the brake rail opening distance is as follows: L=D+C1+C2+T, formula (1); In formula (1), L is the opening distance between the left brake rail 100 and the right brake rail 200; D is the distance between the left side of the sensor 209 and the right side of the first test board 2031; C1 is the lateral thickness of the first test board 2031; C2 is the lateral thickness of the second test board 2032; T is the lateral thickness of the sensor 209 housing (e.g., rectangular in shape); It should be noted that, in this invention, the walking device 1 lifts the testing device 2 via the connecting plate 3, and they walk together on the two brake rails (left brake rail 100 and right brake rail 200). The device stops at the position where the opening distance needs to be measured, and the testing device 2 is lowered. The limiting frame 204 is released (so that the opposite sides of the two limiting plates 2041 in the two limiting frames 204 no longer abut against the opposite sides of the first test plate 2031 and the second test plate 2032 on the first slider 2051 and the second slider 2052). Under the elastic force of the spring 206, the first test plate 2031 and the second test plate 2032 begin to approach the two brake rails. After the first test plate 2031 and the second test plate 2032 (the opposite sides of the two test plates are the measurement reference surfaces) are completely close to the brake rail surfaces 400 of the two brake rails, the sensor 209 on the second test plate 2032 measures the distance to the opposite first test plate 2031 (i.e., the sensor test distance D). In this invention, the opening distance between the left brake rail 100 and the right brake rail 200 is equal to the sum of the sensor test distance D, the thickness of the two test plates, and the lateral thickness of the sensor itself.
[0043] After the test is completed, the two test plates are pressed back to the center position. After rotating the limiting plate and distributing it horizontally and longitudinally, the limiting plate is used to limit the two sliders and the two test plates on the two sliders. At the same time, the lower test device 2 is lifted by the lifting column 4 and then moves to the next test position together with the upper walking device.
[0044] It should be noted that when the limit bracket 204 is released, that is, the limit plate 2041 does not limit the slider. When the limit plate is rotated so that it is not in contact with the slider, it is released; when the limit plate is rotated so that it is in contact with the slider, it is in the limit state.
[0045] Example 3 In this invention, the auxiliary detection device for the distance between the openings of the two brake rails of the vehicle reducer provided by this invention also includes an industrial control computer; An industrial control computer is connected to the sensor 209 to collect the distance D between the left side of the sensor 209 and the right side of the first test plate 2031 (specifically, the right side of the first vertical plate 20310 on the top of the first test plate 2031). Then, according to the calculation formula (1), the opening distance L between the left brake rail 100 and the right brake rail 200 is calculated.
[0046] Example 4 In a specific implementation of this invention, the auxiliary detection device for the distance between the openings of the two brake rails of a vehicle reducer provided by this invention also includes an industrial control computer (specifically, it may be an industrial control computer). Figure 3 The industrial control touch screen 101 shown). An industrial control computer is connected to sensor 209 via communication (either wired or wireless) to collect the distance D between the left side of sensor 209 and the right side of the first test board 2031 (specifically, the right side of the vertical plate at the top of the first test board 2031), and displays it on a display screen on its top. At this point, the operator can calculate the opening distance L between the left brake rail 100 and the right brake rail 200 using the calculation formula (1) and the distance D displayed on the screen.
[0047] In practical implementation, industrial control computers can provide... Figure 3 The industrial control touch screen 101 shown is shown. The industrial control touch screen 101 is located at the top center of the top cover plate 1021.
[0048] It should be noted that industrial control touch screens are existing, mature, and widely used devices. For example, the MT8071IE touch screen manufactured by Weintek Technology Co., Ltd. can be used to display test data here.
[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
