Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to a measuring tool for anchor bolt holes in high-speed railway bearing pads. Background Technology

[0002] A measuring tool is a tool used to measure a certain property. These include length, temperature, time, mass, force, current, voltage, resistance, sound, radio waves, refractive index, and average dispersion. When installing anchor bolts for railway pad bearings, it is necessary to measure the anchor bolt holes to ensure installation accuracy.

[0003] The existing measurement method uses a ruler to repeatedly measure the position of the anchor bolt hole to ensure the accuracy of the measurement, thereby ensuring that the anchor bolt has sufficient stability when fixing the pad stone and ensuring that the fixed position of the pad stone will not shift, thus ensuring the safety of railway operation.

[0004] However, repeatedly measuring with a ruler results in a long installation time for each bearing pad. With hundreds of bearing pads on a single railway line, each measurement requires repeated recording, leading to low measurement efficiency. Therefore, this invention proposes a tool for measuring anchor bolt holes in high-speed railway bearing pads. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the method of repeatedly measuring with a ruler results in a long installation time for each pad stone.

[0008] The surface of the measuring plate is provided with horizontal and vertical support anchor bolt holes. There are four sets of horizontal and vertical support anchor bolt holes arranged in a rectangular array. The centers of the horizontal and vertical support anchor bolt holes are connected to each other. The centers of the horizontal and vertical support anchor bolt holes are closer to the edge of the measuring plate than the multiple support anchor bolt holes and the fixed support anchor bolt holes. The storage box is provided with an elastic component, which is used to control the rotation of the rotating rod.

[0009] Optionally, the elastic component includes a rotating shaft, which is fixedly connected to one end of a rotating rod, and a coil spring is fixedly connected to the outside of the rotating shaft.

[0010] Optionally, a positioning shell is fixedly connected to the end of the coil spring away from the rotation axis, and the positioning shell is fixedly connected to the outside of the storage box.

[0011] Optionally, a gear is fixedly connected to the end of the rotating rod away from the rotating shaft, a positioning block is fitted outside the gear, the positioning block is slidably connected to the outside of the storage box, the positioning block is trapezoidal, and a pull block is fixedly connected to the side of the positioning block away from the storage box.

[0012] Optionally, a spring is fixedly connected to the side of the positioning block away from the gear, and a positioning plate is fixedly connected to the end of the spring away from the positioning block. The positioning plate is fixedly connected to the outside of the storage box.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention employs a combination of multiple support anchor bolt holes, fixed support anchor bolt holes, and transverse and longitudinal support anchor bolt holes on the surface of the measuring plate, which allows for more convenient and accurate measurement of the pad stone anchor bolt holes. Furthermore, during tensile measurement, the connecting plate also drives the cleaning plate to clean the measurement position, thereby ensuring that the measurement is not affected and improving the accuracy and convenience of the measurement.

[0031] Example

[0032] like Figure 1 As shown, this utility model proposes a measuring tool for anchor bolt holes of high-speed railway bearing pads, including a storage box 1. A rotating rod 2 is rotatably connected inside the storage box 1, and a measuring plate 3 is fixedly connected to the outside of the rotating rod 2. The measuring plate 3 can be used to measure the anchor bolt holes of the bearing pads and can also be used to align the center of the bearing. A connecting plate 10 is fixedly connected to the end of the measuring plate 3 away from the rotating rod 2. The connecting plate 10 is used to pull the measuring plate 3 out of the storage box 1. Multiple anchor bolt holes 4 are provided on the surface of the measuring plate 3. There are four groups of anchor bolt holes 4 arranged in a rectangular array. By coordinating the multiple anchor bolt holes 4, the position of the anchor bolt holes of the bearing can be accurately measured. The centers of the multiple anchor bolt holes 4 are interconnected. The surface of the measuring plate 3 is close to the multiple bearing pads. Anchor bolt holes 4 are provided with fixed support anchor bolt holes 5. There are four sets of fixed support anchor bolt holes 5 arranged in a rectangular array. The measurement is more accurate when the fixed support anchor bolt holes 5 are used in conjunction with the multi-support anchor bolt holes 4. The centers of the fixed support anchor bolt holes 5 are connected to each other, and the line used to connect the centers of the fixed support anchor bolt holes 5 is tangent to the outside of the multi-support anchor bolt holes 4. The surface of the measuring plate 3 is provided with horizontal and vertical support anchor bolt holes 6. There are four sets of horizontal and vertical support anchor bolt holes 6 arranged in a rectangular array. The horizontal and vertical support anchor bolt holes 6 are used in conjunction with the fixed support anchor bolt holes 5 and the multi-support anchor bolt holes 4 to make the measurement more convenient. The centers of the horizontal and vertical support anchor bolt holes 6 are connected to each other, and the centers of the horizontal and vertical support anchor bolt holes 6 are closer to the edge of the measuring plate 3 than the multi-support anchor bolt holes 4 and the fixed support anchor bolt holes 5.

[0033] For further details, please refer to Figures 1 to 3 The storage box 1 has an external elastic component that controls the rotation of the rotating rod 2. The elastic component includes a rotating shaft 8, which is fixedly connected to one end of the rotating rod 2 and can rotate with it. A coil spring 7 is fixedly connected to the outside of the rotating shaft 8. When the rotating shaft 8 rotates, it causes the coil spring 7 to coil. A positioning shell 9 is fixedly connected to the end of the coil spring 7 away from the rotating shaft 8. The positioning shell 9 is fixedly connected to the outside of the storage box 1 and is used to fix the position of the coil spring 7 outside the storage box 1. A pressing handle 19 is fixedly connected to the top of the storage box 1. The pressing handle 19 can press down the storage box 1. A tension handle 20 is fixedly connected to the side of the connecting plate 10 away from the measuring plate 3. The tension handle 20 can drive the connecting plate 10 to move. A cleaning plate 11 is embedded inside the connecting plate 10. The cleaning plate 11 can move together with the connecting plate 10 to clean the pad support. The cleaning plate 11 is set in a "T" shape near the connecting plate 10. The structure of the cleaning plate 11 inside the connecting plate 10 makes its installation effect more stable.

[0034] For further details, please refer to Figures 1 to 3 A gear 12 is fixedly connected to the end of the rotating rod 2 away from the rotating shaft 8. The gear 12 can rotate together with the rotating rod 2. A positioning block 13 is fitted outside the gear 12. The positioning block 13 can limit the gear 12 in one direction. The positioning block 13 is slidably connected to the outside of the storage box 1. The positioning block 13 is trapezoidal in shape. The beveled surface of the positioning block 13 ensures the smoothness of the rotation of the gear 12. A pulling block 18 is fixedly connected to the side of the positioning block 13 away from the storage box 1. The pulling block 18 can pull the positioning block 13 to move. A spring 14 is fixedly connected to the side of the positioning block 13 away from the gear 12. A positioning plate 15 is fixedly connected to the end of the spring 14 away from the positioning block 13. The spring 14 can extend and retract between the positioning block 13 and the positioning plate 15, thereby allowing the positioning block 13 to fit tightly with the gear 12 and restricting the rotation of the gear 12. The positioning plate 15 is fixedly connected to the outside of the storage box 1. A sliding rod 16 is fixedly connected to the side of the positioning block 13 near the spring 14. The sliding rod 16 is slidably connected to the inside of the positioning plate 15 at a position away from the positioning block 13. The sliding method of the sliding rod 16 inside the positioning plate 15 can restrict the sliding position of the positioning block 13. A limit block 17 is fixedly connected to the end of the sliding rod 16 away from the positioning block 13. The limit block 17 can prevent the sliding rod 16 from detaching from the inside of the positioning plate 15.

[0035] In this embodiment, when measuring the gap of the pad anchor bolt, first hold the downward handle 19 and let the downward handle 19 move the storage box 1 and the connecting plate 10, so that the cleaning plate 11 can clean the dust and impurities at the measurement position. Then, hold the stretch handle 20 and pull it outward. At this time, the connecting plate 10 will drive the measuring piece 3 to extend out of the storage box 1. After the measuring piece 3 extends out, it can be used for measurement.

[0036] During measurement, align the center of measuring piece 3 with the center of the support. Then, the multiple anchor bolt holes 4 of the support can correspond to the multiple anchor bolt holes of the pad stone. At this time, the anchor bolt holes 5 of the fixed support can be aligned with the position to be installed. The anchor bolt holes 6 of the transverse and longitudinal supports can be used to measure the transverse support and the longitudinal anchor bolt holes, thereby determining whether the hole position is qualified.

[0037] When the connecting plate 10 pulls the measuring piece 3, the connecting plate 10 can also further clean the measuring position. When the measuring piece 3 is pulled out, it will also drive the rotating shaft 8 to drive the coil spring 7 to coil inside the positioning shell 9. When the rotating rod 2 drives the coil spring 7 to coil, it will also drive the gear 12 to rotate. The gear 12 relies on the trapezoidal structure of the positioning block 13 to provide a certain resistance when it is pulled out. After the connecting plate 10 is released, the plane of the positioning block 13 ensures that the gear 12 will not cause the rotating rod 2 to reset and rotate due to the elastic force of the coil spring 7.

[0038] When the positioning block 13 restricts the gear 12, the spring 14 will push the positioning block 13 to fit tightly against the outside of the gear 12 on one side of the positioning plate 15. The positioning block 13 restricts its position by sliding the sliding rod 16 inside the positioning plate 15. When the positioning block 13 is embedded in the outside of the gear 12, the limiting block 17 can also restrict the sliding rod 16 and the positioning block 13 to avoid the positioning block 13 applying pressure to the gear 12 for a long time, which would damage the rotation position of the rotating rod 2.

[0039] After the measurement is completed, the pull block 18 can be pulled to compress the spring 14. The pull block 18 will also cause the sliding rod 16 to slide along the inside of the positioning plate 15, thereby causing the positioning block 13 to disengage from the outside of the gear 12. At this time, the elastic force of the coil spring 7 is released, thereby causing the rotating shaft 8 and the rotating rod 2 to rotate. In this way, the rotating rod 2 can rewind the measuring piece 3 back into the storage box 1. Then the pull block 18 can be released, and the spring 14 can push the positioning block 13 to restrict the gear 12.

[0040] It should be noted that this device uses multiple support anchor bolt holes 4, fixed support anchor bolt holes 5 and transverse and longitudinal support anchor bolt holes 6 on the surface of the measuring plate 3 to cooperate with each other, which can make it more convenient and accurate to measure the anchor bolt holes of the pad stone. In addition, during tensile measurement, the connecting plate 10 will also drive the cleaning plate 11 to clean the measurement position, thereby ensuring that the measurement is not affected and improving the accuracy and convenience of the measurement.

[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
