Description

A railway track spacing measuring device after installation Technical Field

[0001] This utility model belongs to the field of track installation technology, specifically relating to a spacing measuring device after railway track installation. Background Technology

[0002] A railway track is a rail line used by trains and other vehicles. It mainly consists of two parallel steel rails fixed to sleepers, with ballast underneath. The primary function of a railway track is to allow trains to travel without needing to turn. With the development of the Industrial Revolution, railway transportation gradually became a major mode of land transport. Early railway tracks mainly consisted of wooden sleepers and rails. With technological advancements, modern railway tracks have gradually adopted concrete sleepers and stronger steel rails. Currently, railway transportation is still widely used globally, and with technological progress, such as the emergence of high-speed rail and maglev trains, the efficiency and comfort of railway transportation continue to improve.

[0003] After the rails are installed on a railway track, it is necessary to measure the distance between them to ensure good parallelism. This measurement requires a special track gauge, a specialized measuring instrument used to measure the distance between the two rails of a railway line. The track gauge is characterized by its composite measuring rod, consisting of a wooden rod and a metal rod joined together by a folding mechanism.

[0004] Existing track gauges are all operated by lifting and placing them using the handle at the top. After measuring one position, one needs to bend over to lift the track gauge and change its position to measure the next position. Repeated bending over reduces work efficiency and can easily cause discomfort to the lower back. Therefore, we propose a track gauge spacing measuring device after the railway track is installed. Summary of the Invention

[0005] The purpose of this utility model is to provide a track gauge measuring device after railway track installation, in order to solve the problem mentioned in the background art that the existing track gauge is lifted and placed by the handle on the top. After measuring one position, it is necessary to bend over to lift the track gauge to change the position and measure the next position. Repeated bending over reduces work efficiency and easily causes discomfort to the waist.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a track gauge measuring device after track installation, comprising a track gauge body, a fixed seat one fixedly mounted on the surface of the track gauge body, a rotating shaft one rotatably mounted on the fixed seat one, a rotating seat fixedly mounted on the outer surface of the rotating shaft one, a rotating shaft two fixedly mounted on the rotating seat, a fixed seat two rotatably mounted on the outer surface of the rotating shaft two, a mounting shell fixedly mounted on the surface of the fixed seat two, an inner mounting rod slidably mounted inside the mounting shell, one end of the inner mounting rod slidably extending out of the mounting shell and fixedly mounted with a handrail, and a retaining plate slidably provided on the side of the track gauge body.

[0007] The above scheme utilizes a combination of fixed base one, a rotating base, and fixed base two to mount the outer casing and the inner rod. The handle on the inner rod allows for easy movement of the gauge ruler without bending over, improving operational convenience. The rotating base rotates between itself and both fixed bases one and two, allowing the outer casing to be folded and stored after use for convenient carrying. A retaining plate works in conjunction with a foot pedal. During measurement, the foot is placed on the foot pedal, causing the guide rod to move the retaining plate downwards, thus limiting the gauge ruler's position and preventing displacement. Spring two deforms during this process, and when the foot leaves the foot pedal, the spring force causes the retaining plate to quickly move upwards to reset, enhancing measurement stability.

[0008] In a preferred embodiment, a fixing screw is fixedly installed on the side of the rotating seat, and an arc-shaped slide is provided on the fixing seat. The arc-shaped slide is coaxially arranged with the rotating shaft, and the fixing screw passes through the arc-shaped slide and is threaded with a nut.

[0009] Using the above solution, by setting a fixing screw to pass through the arc-shaped slide and cooperating with nut one, the rotation of the rotating seat can be realized. Then, by fixing seat two, the tilt adjustment of the outer shell and the inner rod can be realized, which is convenient for pushing and using.

[0010] In a preferred embodiment, a washer is attached to the side of the nut, a limiting block is fixedly installed on the side of the washer, the washer is attached to the side of the fixing seat, and limiting grooves are provided at both ends of the arc-shaped slide on the side of the fixing seat. The limiting block and the limiting groove are used in conjunction.

[0011] By using the above solution and the shims, the surface of the fixed seat can be prevented from being squeezed and damaged when the nut is turned. The position is limited by inserting the limit block into the limit groove, which prevents accidental loosening.

[0012] In a preferred embodiment, a sliding rod is slidably mounted on the fixed base 2, and an operating plate and a locking plate are respectively fixedly mounted at both ends of the sliding rod. A spring 1 is fixedly mounted between the operating plate and the inner wall of the fixed base 2. Two locking slots are opened on the rotating base, and the two locking slots are arranged at a 90-degree angle with the axis of the rotating shaft 2. The locking plate and the locking slots are used in conjunction.

[0013] By adopting the above solution, the elastic force of spring one is used in conjunction with the locking plate, so that the locking plate can move quickly and lock into the locking slot, thus achieving convenient locking operation.

[0014] In a preferred embodiment, a movable screw is provided at the end of the mounting housing, and a nut is threaded onto the outer surface of the movable screw. Several through holes are provided on the mounting inner rod, and the movable screw is used in conjunction with the through holes.

[0015] By using the above solution, the position of the inner rod and the outer shell can be locked by using the movable screw through the through hole and in conjunction with the second nut, thereby achieving adaptive adjustment of the handrail operating height.

[0016] In a preferred embodiment, a mounting bracket is fixedly installed on the surface of the gauge body, a rubber plate is fixedly installed on the inner wall of the mounting bracket, and a slot is provided on the side of the end of the mounting housing. The rubber plate and the slot are used in conjunction.

[0017] Using the above solution, the mounting base and rubber plate are used in conjunction with the slot. After the mounting shell is rotated and retracted, the mounting shell is inserted into the mounting base, and the rubber plate is inserted into the slot, thus realizing the retraction and locking of the mounting shell. This is convenient to operate and avoids shaking.

[0018] In a preferred embodiment, a fixing plate is fixedly installed on the side of the gauge body, a guide rod is slidably installed on the fixing plate, a foot pedal is fixedly installed at the top of the guide rod, the bottom of the guide rod is fixedly connected to the fixing plate, and a spring is sleeved on the outside of the guide rod, with its two ends respectively connected to the fixing plate and the fixing plate.

[0019] Using the above scheme, the guide rod is used in conjunction with spring two. When measuring, the foot is placed on the foot pedal, which drives the guide rod to move the fixing plate downward, thereby limiting the position of the gauge body and preventing displacement. At this time, spring two deforms, so when the foot is removed from the foot pedal, the elastic force of spring two can be used to drive the fixing plate to move upward quickly and reset.

[0020] In a preferred embodiment, an anti-slip toothed plate is fixedly installed on the lower surface of the retaining plate, with the anti-slip teeth of the anti-slip toothed plate facing downwards.

[0021] By adopting the above solution, the anti-slip toothed plate can improve the stability of the retention effect and prevent slippage.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The track gauge measurement device after installation uses a fixed base one, a rotating base and a fixed base two to install the outer shell and the inner rod. The handrail on the inner rod can be used to push the track gauge body to move and measure without bending over, which improves the convenience of measurement operation. The rotating base is rotatably set with both fixed base one and fixed base two, so the outer shell can be rotated and folded after use, making it convenient to carry and use as a whole.

[0024] The track gauge spacing measuring device installed on the railway track uses a fixed plate in conjunction with a foot pedal. When measuring, the foot is placed on the foot pedal, which drives the guide rod to move the fixed plate downward, thus limiting the position of the main body of the gauge and preventing displacement. At this time, the second spring deforms. Therefore, when the foot is removed from the foot pedal, the elastic force of the second spring can drive the fixed plate to move upward quickly to reset, improving the measurement stability.

[0033] Please refer to Figures 1-7. This utility model provides a track gauge body 1 after track gauge installation. A fixed seat 2 is fixedly installed on the surface of the track gauge body 1. A rotating shaft 3 is rotatably installed on the fixed seat 2. A rotating seat 4 is fixedly installed on the outer surface of the rotating shaft 3. A rotating shaft 5 is fixedly installed on the rotating seat 4. A fixed seat 6 is rotatably installed on the outer surface of the rotating shaft 5. An installation shell 7 is fixedly installed on the surface of the fixed seat 6. An inner mounting rod 8 is slidably installed inside the installation shell 7. One end of the inner mounting rod 8 slidably extends out of the installation shell 7 and is fixedly installed with a handrail 9. A retaining plate 10 is slidably provided on the side of the track gauge body 1.

[0034] By using a fixed base 2, a rotating base 4, and a fixed base 6 to cooperate in the installation of the outer casing 7 and the inner rod 8, and by using the handle 9 on the inner rod 8, the main body 1 of the gauge ruler can be moved and measured without bending over, improving the convenience of measurement operation. The rotating base 4 is rotatably connected to both the fixed base 2 and the fixed base 6, so the outer casing 7 can be rotated and folded away after use for easy carrying. By using a retaining plate 10 in conjunction with a foot pedal 25, when the foot is placed on the foot pedal 25, the guide rod 24 drives the retaining plate 10 to move downward, thus limiting the position of the main body 1 of the gauge ruler and preventing displacement. At this time, the spring 26 deforms, so when the foot is removed from the foot pedal 25, the elasticity of the spring 26 can drive the retaining plate 10 to move upward quickly and reset, improving measurement stability.

[0035] A fixing screw 11 is fixedly installed on the side of the rotating seat 4. An arc-shaped slide is provided on the fixing seat 2, and the arc-shaped slide is arranged coaxially with the rotating shaft 3. The fixing screw 11 passes through the arc-shaped slide and is threaded with a nut 14. By setting the fixing screw 11 to pass through the arc-shaped slide and cooperate with the nut 14, the rotating seat 4 can be rotated. Then, the tilt adjustment of the mounting shell 7 and the mounting inner rod 8 can be realized through the fixing seat 2 6, which is convenient for pushing and using.

[0036] A washer 12 is attached to the side of the nut 14, and a limiting block 13 is fixedly installed on the side of the washer 12. The washer 12 is attached to the side of the fixed seat 2. Limiting grooves are opened at both ends of the arc-shaped slide on the side of the fixed seat 2. The limiting block 13 and the limiting groove are used together. With the help of the washer 12, the surface of the fixed seat 2 can be prevented from being squeezed and damaged when the nut 14 is turned. The limiting block 13 is inserted into the limiting groove to achieve a position limiting effect and prevent accidental loosening.

[0037] A sliding rod 15 is slidably mounted on the fixed base 2 6. An operating plate 16 and a locking plate 17 are fixedly mounted on both ends of the sliding rod 15, respectively. A spring 18 is fixedly installed between the operating plate 16 and the inner wall of the fixed base 2 6. Two locking slots are opened on the rotating base 4. The two locking slots are arranged at a 90-degree angle with the axis of the rotating shaft 2 5. The locking plate 17 and the locking slots are used in conjunction. The elastic force of the spring 18 is used to cooperate with the locking plate 17, so that the locking plate 17 can move quickly and lock into the locking slot, realizing the convenience of locking operation.

[0038] A movable screw 19 is inserted through the end of the housing 7. A nut 20 is threaded on the outer surface of the movable screw 19. Several through holes are provided on the inner rod 8. The movable screw 19 is used in conjunction with the through holes. By using the movable screw 19 through the through holes and in conjunction with the nut 20, the positions of the inner rod 8 and the housing 7 can be locked, thereby achieving the adaptive adjustment of the operating height of the handrail 9.

[0039] A mounting base 21 is fixedly installed on the surface of the main body 1 of the gauge ruler. A rubber plate 22 is fixedly installed on the inner wall of the mounting base 21. A slot is opened on the side of the end of the mounting shell 7. The rubber plate 22 and the slot work together. By using the mounting base 21 and the rubber plate 22 to work together with the slot, after the mounting shell 7 is rotated and retracted, the mounting shell 7 is inserted into the mounting base 21 and the rubber plate 22 is inserted into the slot, realizing the retraction and locking of the mounting shell 7. The operation is convenient and avoids shaking.

[0040] A fixing plate 23 is fixedly installed on the side of the main body 1 of the gauge ruler. A guide rod 24 is slidably installed on the fixing plate 23. A foot pedal 25 is fixedly installed on the top of the guide rod 24. The bottom end of the guide rod 24 is fixedly connected to the fixing plate 10. A spring 26 is sleeved on the outside of the guide rod 24, with its two ends connected to the fixing plate 23 and the fixing plate 10 respectively. When the guide rod 24 is used in conjunction with the spring 26, the foot steps on the foot pedal 25 during measurement, which drives the guide rod 24 to move the fixing plate 10 downward, thereby limiting the position of the main body 1 of the gauge ruler and preventing displacement. At this time, the spring 26 deforms. Therefore, when the foot leaves the foot pedal 25, the elastic force of the spring 26 can drive the fixing plate 10 to move upward quickly and reset.

[0041] An anti-slip toothed plate 27 is fixedly installed on the lower surface of the retaining plate 10. The anti-slip teeth of the anti-slip toothed plate 27 are arranged with the anti-slip teeth facing downward. The setting of the anti-slip toothed plate 27 can improve the stability of the retaining effect and avoid slippage.

[0042] During use, the measuring personnel adjust the height of the handrail 9 according to their own usage habits. To adjust, unscrew nut 20 and pull out the movable screw 19. This unlocks the inner rod 8 and the outer casing 7. Holding the inner rod 8, slide it inside the outer casing 7. Once in the desired position, insert the movable screw 19 and tighten nut 20 to lock it in place, thus adjusting the height of the handrail 9. After adjustment, the handrail 9 pushes the gauge body 1 along the two railway tracks for precise measurement. During measurement, the foot rests on the foot pedal 25, which drives the guide rod 24 to move the retaining plate 10 downwards. This causes the retaining plate 10 to contact the ground via the anti-slip toothed plate 27, ensuring the stability of the gauge body 1 and preventing deviation. After measurement, the foot leaves the foot pedal 25, and the spring force of spring 26 causes the retaining plate 10 to move upwards and reset. The outer casing 7 then needs to be adjusted. When folding, unscrew nut 14 and remove washer 12. At this time, the rotating seat 4 and the fixed seat 2 are unlocked. The rotating seat 4 is rotated to a vertical position through the rotating shaft 3. At this time, the mounting shell 7 will rotate to a vertical position simultaneously. Then, put on washer 12 and tighten nut 14 to lock it. Then pull the operating plate 16 to drive the sliding rod 15 to drive the locking plate 17 to move, so that the locking plate 17 is disengaged from the locking groove. At this time, the rotating seat 4 and the fixed seat 6 are unlocked. The fixed seat 6 is rotated to a horizontal position through the rotating shaft 5. At this time, the mounting shell 7 is also rotated to a horizontal position. At this time, release the operating plate 16. The elastic force of spring 18 will drive the locking plate 17 to lock into another locking groove, realizing the locking of one end of the mounting shell 7. At the same time, the other end of the mounting shell 7 will be locked into the locking seat 21, and the rubber locking plate 22 will be locked into the locking groove, realizing the locking of the other end of the mounting shell 7.
