Description

Technical Field

[0001] The utility model relates to the technical field of rail measurement, in particular to a portable push-type digital display rail gauge. Background Art

[0002] The railway track gauge (abbreviated as track gauge) is an important railway-specific measuring instrument that provides a direct technical basis for line maintenance and construction. It is mainly used for static measurement of these geometric parameters. It also has the function of measuring the inspection interval and back guard distance of turnouts. It can be used for engineering maintenance, overhaul, engineering surveying and other line operations of relevant departments.

[0003] When measuring the railway gauge, it is convenient for the workers to measure a single measuring point. However, when multiple points need to be measured, since the gauge needs to be constantly moved between multiple measuring points, the workers need to stand up, bend over or squat down many times to move or carry the gauge. The labor intensity of the workers is high, the workers are easily tired, and the work efficiency is low.

[0004] For example, the patent with publication number CN215832635U discloses a portable push-type track gauge ruler, which includes a ruler rod and a fixed measuring seat and a movable measuring seat arranged at both ends of the ruler rod. The fixed measuring seat is connected to one end of the ruler rod in a "T" shape, and a first rolling wheel is arranged at each end. A second rolling wheel is arranged under the movable measuring seat. The track gauge ruler is supported to move on the rails by three walking wheels connected to the bottom of the movable measuring seat and the fixed measuring seat. A push rod for pushing the track gauge ruler is arranged on the side of the ruler rod. When measurement is required, only the push rod needs to be pushed, thereby avoiding the measurement worker from bending over to place the track gauge ruler, thereby reducing the labor intensity of the measurement personnel.

[0005] Although the above-mentioned track gauge can greatly reduce the labor intensity of surveyors and improve work efficiency during use, the applicant has found that it has certain defects during actual use. Specifically, in the existing track laying, in order to compensate for the thermal expansion and contraction of the rails caused by temperature changes, a certain gap is set between the two butted rails. In order for the above-mentioned track gauge to be able to travel on the rails, the axial direction of the running wheels is perpendicular to the axial direction of the rails. In this way, the running wheels will generate additional impact and vibration when passing through the gap between the rails, which will cause additional pressure on the track gauge and accelerate the wear of the track gauge. At the same time, the movement of the track gauge on the rails is not smooth, affecting the user experience. Utility Model Content

[0038] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1 As shown, combined Figure 2 The embodiment of the utility model provides a portable push-type digital track gauge, comprising a track gauge body 1, fixed measuring devices 2 and movable measuring devices 3 arranged at both ends of the track gauge body 1 in the length direction, and a push rod 6 arranged on the track gauge body 1.

[0040] The fixed measuring device 2 is used to support one end of the track gauge body 1 and is installed on the rail S as a positioning basis. Specifically, the fixed measuring device 2 of this embodiment includes a mounting plate 21, a first measuring wheel 22 and a first running wheel 23.

[0041] The mounting plate 21 is horizontally fixedly arranged at one end of the track gauge body 1, and the length direction of the mounting plate 21 is perpendicular to the length direction of the track gauge body 1. Two first measuring wheels 22 and two first running wheels 23 are provided. The two first measuring wheels 22 are respectively arranged at the bottom surfaces of both ends of the length direction of the mounting plate 21, and the two first running wheels 23 are respectively arranged horizontally and rotatably at the bottom surfaces of both ends of the length direction of the mounting plate 21. In this arrangement, one end of the track gauge body 1 can be supported by two first running wheels 23 arranged at intervals, and at the same time, the two first running wheels 23 run on the top surface of the rail. In actual use, the two first measuring wheels 22 are in contact with the inner side wall of one of the rails. When the first running wheels 23 run, the first measuring wheels 22 roll along the inner side wall of the rail.

[0042] In order to measure the distance between two rails, the present embodiment cooperates with a movable measuring device 3 and a fixed measuring device 2. Specifically, the movable measuring device 3 includes a second measuring wheel 31 and a second running wheel 32 arranged at the other end of the track gauge body 1. The second running wheel 32 and the second measuring wheel 31 can slide horizontally along the length direction of the track gauge body 1 synchronously. In the present embodiment, the bottom surfaces of the second running wheel 32 and the first running wheel 23 are located on the same horizontal plane. Thus, when the entire track gauge is placed horizontally between the two rails, the first running wheel 23 and the second running wheel 32 are respectively used for rolling connection with the top surface of the rail. Since the first running wheel 23 is set to two and the second running wheel 32 is set to one, the three points are coplanar, so that the entire track gauge can be stably supported between the two rails. At the same time, when the first running wheel 23 and the second running wheel 32 cooperate with each other to slide on the rail, the entire track gauge can be translated along the axial direction of the rail.

[0043] In this embodiment, the first measuring wheel 22 and the second measuring wheel 31 are respectively used for rolling connection with the inner wall of the rail, and the first measuring wheel 22 and the second measuring wheel 31 are located between the first running wheel 23 and the second running wheel 32 .

[0044] When measuring the track gauge of a rail, first place the first running wheel 23 on the top surface of the first rail, then make the first measuring wheel 22 contact the inner side wall of the first rail, then move the second measuring wheel 31 and the second running wheel 32 on the track gauge body 1 toward the movable measuring device 3 synchronously, so that the second measuring wheel 31 contacts the inner side wall of the second rail, and at the same time, the second running wheel 32 contacts the top surface of the second rail, and the track gauge between the two rails can be measured through the distance measuring assembly 12 on the track gauge body 1.

[0045] When it is necessary to measure different positions of the rails, it is only necessary to use the push rod 6 to push the track gauge body 1 so that the track gauge body 1 can be translated between the two rails through the first running wheel 23 and the second running wheel 32. After the entire track gauge is moved to the appropriate position, the distance measuring component 12 on the track gauge body 1 can be used to measure the rail gauge.

[0046] Since the existing rails are not made of an independent rail, multiple rails are usually connected to form one rail for use. Since a certain gap is set between the two connected rails, when the axis of the running wheel is perpendicular to the axis of the rail, the running wheel will generate additional impact and vibration when passing through the gap between the rails, which will cause additional pressure on the track gauge and accelerate the wear of the track gauge. At the same time, the movement of the track gauge on the rail is not smooth, affecting the user experience.

[0047] To this end, this embodiment is improved on the basis of the existing track gauge structure. Specifically, the solution adopted in this embodiment is: the axes of the first running wheel 23 and the second running wheel 32 are at a certain angle to the length direction of the track gauge body 1. In this way, when the running wheel passes through the gap obliquely, a part of the running wheel will first contact the opposite track, so that the running wheel can pass over the opposite track more smoothly, instead of directly crossing the gap vertically. Since the entire running wheel does not cross the gap at the same time, but gradually transfers the contact point, the impact force of the running wheel at the gap can be dispersed, the vibration can be reduced, thereby reducing the wear of the running wheel at the gap and increasing the service life of the track gauge. In addition, the inclined running wheel can smoothly cross the gap, making the track gauge smoother when moving horizontally on the rail, enhancing the user experience.

[0048] As some preferred embodiments, the angle between the axis of the first running wheel 23 and the second running wheel 32 and the length direction of the track gauge body 1 is 10° to 30°. Specifically, when the angle is less than 10°, when the running wheel crosses the opposite track, a longer part of the running wheel will contact the gap, causing the running wheel to impact when crossing the gap. When the angle is greater than 30°, there is a certain offset force component during the running of the running wheel, which makes the pushing process more laborious. Therefore, this embodiment sets the angle to 10° to 30°. While considering the width of the existing joint track gap, the running wheel can smoothly cross the track gap, avoid or reduce the impact and vibration of the track gap on the running wheel, and improve the service life of the track gauge.

[0049] See attached Figure 2As shown, in order to make the entire track gauge ruler run smoothly between the two rails, in this embodiment, the end of the track gauge ruler body 1 is fixedly connected to the middle of the mounting plate 21, and the two first measuring wheels 22 and the two first running wheels 23 are symmetrically arranged on the bottom surfaces of the two ends of the mounting plate 21 in the length direction relative to the central axis of the track gauge ruler body 1. In this way, the connection line of the second measuring wheel 31 and the two first measuring wheels 22 forms an isosceles triangle, and the connection line of the second running wheel 32 and the two first running wheels 23 forms an isosceles triangle, thereby ensuring that the track gauge ruler body 1 is stably and reliably supported on the surfaces of the two rails, and the overall structural strength is more stable.

[0050] The first measuring wheel 22 is located at one end of the mounting plate 21 close to the movable measuring device 3, a first connecting rod 24 is fixedly arranged on the bottom surface of the mounting plate 21, the first measuring wheel 22 is horizontally rotatably arranged at the bottom end of the first connecting rod 24, and a first rotating seat 25 for mounting the first running wheel 23 is also arranged on the bottom surface of the mounting plate 21. Through the arrangement of the first connecting rod 24, the position of the first measuring wheel 22 on the bottom surface of the mounting plate 21 can be adjusted, so that the first measuring wheel 22 can be conveniently assembled with the mounting plate 21 by means of the first connecting rod 24, and the arrangement of the first rotating seat 25 can facilitate the assembly of the first running wheel 23 on the mounting plate 21.

[0051] As some preferred embodiments, a locking member 26 is provided on the top surface of the mounting plate 21, and the locking member 26 is used to fix or release the position of the first running wheel 23 relative to the first rotating seat 25. When the track gauge is moved to the position to be measured on the rail, the first running wheel 23 and the first rotating seat 25 can be fixed by the locking member 26, so that the entire track gauge remains in place on the rail, which facilitates accurate track gauge measurement at the test position of the rail to be measured.

[0052] The track gauge body 1 of the present embodiment includes a ruler rod 11 having an installation cavity 110 disposed along its length direction. A distance measuring assembly 12 is disposed in the installation cavity 110 and is used to measure the outer distance of the first measuring wheel 22 and the second measuring wheel 31 in the horizontal direction. The outer distance of the first measuring wheel 22 and the second measuring wheel 31 in the horizontal direction measured by the distance measuring assembly 12 can reflect the track gauge between the two rails.

[0053] This embodiment shows a preferred implementation of the activity measurement device 3. Figure 3 As shown, the movable measuring device 3 further includes a slide rail 33 , a slider 34 , a linkage member 35 , a second rotating seat 36 and a second connecting rod 37 .

[0054] The slide rail 33 is horizontally fixedly arranged on the bottom surface of one end of the ruler rod 11 away from the fixed measuring device 2. The second rotating seat 36 is slidably connected to the slide rail 33 through the slider 34. The second walking wheel 32 is rotatably arranged on the second rotating seat 36. The second connecting rod 37 is vertically arranged on the side of the second walking wheel 32 facing the fixed measuring device 2. The upper end of the second connecting rod 37 moves into the interior of the ruler rod 11 and is connected to the distance measuring component 12. The second measuring wheel 31 is horizontally rotatably arranged at the lower end of the second connecting rod 37. The second rotating seat 36 and the second connecting rod 37 are fixedly connected by a linkage 35.

[0055] By adopting the above technical solution, when the spacing between the second measuring wheel 31 and the first measuring wheel 22 changes, the outer distance of the first measuring wheel 22 and the second measuring wheel 31 in the horizontal direction can be measured by the distance measuring assembly 12. At the same time, when the second measuring wheel 31 translates relative to the first measuring wheel 22 on the ruler rod 11, the second measuring wheel 31 can drive the second rotating seat 36 to slide on the slide rail 33 through the linkage 35, thereby making the second measuring wheel 31 and the second running wheel 32 translate synchronously relative to the ruler rod 11. Since the relative positions of the second running wheel 32 and the second measuring wheel 31 remain unchanged, when the spacing between the two rails changes, the second running wheel 32 can adaptively translate horizontally and effectively contact the top surface of the rail, thereby realizing running on the rail in cooperation with the first running wheel 23.

[0056] In order to measure the track gauge of the rail, this embodiment shows a preferred implementation of the distance measuring component 12. Figure 4-6 As shown, the distance measuring assembly 12 includes a wrench 121 , a hinge rod 122 , a pull rod 123 , an elastic member 124 and a displacement sensor 125 .

[0057] Among them, the pull rod 123 is horizontally arranged in the installation cavity 110, one end of the pull rod 123 is fixedly connected to the upper end of the second connecting rod 37, and the other end passes through the displacement sensor 125 fixedly arranged in the installation cavity 110, and the elastic member 124 is sleeved on the pull rod 123; a handle 111 is arranged on the top surface of the ruler rod 11, and the wrench 121 is hinged on the handle 111, and at least a part of the wrench 121 extends into the installation cavity 110, and one end of the pull rod 123 away from the second connecting rod 37 is hinged to the wrench 121 through a hinge rod 122; an inclination sensor 126 is also arranged in the installation cavity 110, and a digital display module 4 is also arranged on the top surface of the ruler rod 11, and the digital display module 4 is respectively connected to the displacement sensor 125 and the inclination sensor 126.

[0058] By adopting the above technical solution, when the wrench 121 is moved, the wrench 121 and the hinge rod 122 form a connecting rod assembly to apply rotational force, transmit the rotational force of the wrench 121 to the hinge rod 122, and pull the pull rod 123 through the hinge rod 122. When the pull rod 123 is pulled, it drives the second connecting rod 37 to translate, and the second connecting rod 37 drives the second measuring wheel 31 to move toward the side of the fixed measuring device 2. The second connecting rod 37 compresses the elastic member 124. At this time, the second measuring wheel 3 1 and the first measuring wheel 22 are reduced. When the first measuring wheel 22 and the second measuring wheel 31 both abut against the inner wall of the rail, the wrench 121 is loosened. Under the preload of the elastic member 124, the pull rod 123 translates in the opposite direction, so that the second measuring wheel 31 abuts against the inner wall of the rail. The displacement of the pull rod 123 can be obtained by the displacement sensor 125, and the inclination angle of the ruler rod 11 can be obtained by the inclination sensor 126, so that the rail gauge and height difference can be calculated and displayed by the digital display module 4.

[0059] In order to facilitate the pushing of the track gauge ruler, the present embodiment is provided with an articulated seat 113 on one side of the ruler rod 11 in the width direction, and a clamping seat 114 is provided on one side of the articulated seat 113 in the horizontal direction. One end of the push rod 6 is hingedly connected to the articulated seat 113, and the other end can be horizontally clamped in the clamping seat 114. Thus, when the track gauge ruler needs to be pushed on the rail, it is only necessary to take the push rod 6 out of the clamping seat 114, and the push rod 6 can be held by hand to push the track gauge ruler body 1 to translate along the axial direction of the rail.

[0060] In order to facilitate the measurement of the track gauge after translation to the test position, a handheld storage button 61 is provided at the end of the push rod 6 away from the hinge seat in this embodiment, and the handheld storage button 61 is electrically connected to the digital display module 4 through a conductive line. According to this arrangement, the track gauge can be measured by pressing the handheld storage button 61 during the pushing process, and the data can be displayed through the digital display module 4 at the same time, without bending over to push the track gauge, which saves time and effort.

[0061] As some preferred embodiments, a mounting bracket 5 is fixedly provided on the mounting plate 21, and a display terminal 51 is detachably provided on the mounting bracket 5. A Bluetooth transmission module is provided in the digital display module 4, and the Bluetooth transmission module is wirelessly connected to the display terminal 51. With the above technical solution, during the implementation process, the measurement is performed by pressing the handheld storage button 61, and the detection data is transmitted to the display terminal 51 in real time, eliminating the process of bending over to adjust and read data, significantly reducing labor intensity and greatly improving work efficiency, so that the line inspection is changed from point measurement to line measurement, and full coverage of the line inspection is achieved. In this embodiment, the display terminal 51 can be a mobile phone, a tablet or other handheld terminal.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
