Description

Technical Field

[0001] The utility model relates to the technical field of railway square rulers, in particular to a new type of railway square ruler. Background Art

[0002] A railway square, also known as a track square, is a measuring tool specifically designed to inspect track geometry and smoothness. Typically consisting of a straightedge, angle square, and level, it can accurately measure track gauge, superelevation, and levelness. These measurements allow engineers to assess track condition, providing crucial insights for railway maintenance and upkeep.

[0003] A new type of railway square ruler is disclosed in the Chinese utility model patent with publication number CN213515475U, which includes a projector laser bracket. A mounting notch is provided at the top of the projector laser bracket. Support plates are fixedly connected to the top of the projector laser bracket and on both sides of the mounting notch. Level meters are provided on the upper surfaces of the two support plates. A projector laser platform is fixedly connected to the top of the projector laser bracket and at the mounting notch. The top of the projector laser platform is fixedly connected to the projector laser body.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when in use, the above-mentioned railway square directly clamps the projector laser bracket with a long angle steel structure on the track, which is easy to shake or even fall off during measurement. It needs to be fixed with the help of other tools or directly by manpower, affecting the accuracy of the measurement. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a new type of railway square.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: A new type of railway square ruler, comprising an L-shaped plate, an installation opening is provided on the L-shaped plate, a mounting plate is provided on the inner wall of the installation opening, a projector laser is provided on the upper surface of the mounting plate, a fixed plate is slidably connected to the bottom of the horizontal part of the L-shaped plate, a slide groove is provided on the bottom of the horizontal part of the L-shaped plate, a driving assembly for driving the fixed plate to move is installed on the L-shaped plate, the driving assembly comprises a slider fixed to the upper surface of the fixed plate and slidably connected to the inner wall of the slide groove, a first screw rod is provided through the side wall of the L-shaped plate and is rotatably connected, and a star-shaped handle fixed to one end of the first screw away from the slider, one end of the first screw is rotatably connected to the inner wall of the slide groove, the first screw passes through the side wall of the slider and is threadedly connected to the slider.

[0007] By adopting the above technical solution, when it is necessary to measure the track, the staff will place the L-shaped plate on the track and press the L-shaped plate against the track, and rotate the first screw rod through the star-shaped handle. Since the first screw rod is threadedly connected to the slider, and the slider is slidingly connected to the inner wall of the slide groove, the slider drives the fixed plate to move axially along the first screw rod, so that the side wall of the fixed plate presses against the side wall of the track, and then the track is measured by the projector laser, which reduces the probability of the L-shaped plate shaking or even falling off during measurement, affecting the measurement accuracy.

[0008] Furthermore, an adjustment groove is opened on the side wall of the fixing plate close to the vertical part of the L-shaped plate, and a reinforcement component is installed on the fixing plate, and the reinforcement component includes a limit plate slidingly connected to the inner wall of the adjustment groove, a second screw rod penetrating the fixing plate and rotatably connected, and a rotating block fixed to the lower end of the second screw rod, the upper end of the second screw rod is rotatably connected to the top wall of the adjustment groove, and the second screw rod passes through the limit plate and is threadedly connected to the limit plate.

[0009] By adopting the above technical solution, after the fixed plate is driven to press against the side wall of the track through the driving assembly, the staff rotates the second screw through the rotating block. Since the second screw is threadedly connected to the limit plate, the limit plate is slidingly connected to the inner wall of the adjustment groove, so that the limit plate moves axially along the second screw, so that the limit plate presses upward against the track, further enhancing the stability of the device.

[0010] Furthermore, a limiting assembly for limiting the rotation of the first screw is installed on the first screw, and the limiting assembly includes a limiting nut sleeved on the first screw and threadedly connected to the first screw.

[0011] By adopting the above technical solution, when the fixing plate is pressed against the side wall of the track, the staff needs to tighten the limiting nut so that the side wall of the limiting nut is pressed against the side wall of the L-shaped plate, thereby limiting the rotation of the first screw and reducing the probability of the fixing plate loosening due to the rotation of the first screw.

[0012] Furthermore, an annular gasket is sleeved on the first screw and is located between the limiting nut and the L-shaped plate.

[0013] By adopting the above technical solution, the annular gasket is made of rubber material, which has greater friction, thereby increasing the friction between the limiting nut and the L-shaped plate and enhancing the limiting effect on the first screw.

[0014] Furthermore, a plurality of rubber pads are fixed to the bottom of the horizontal portion of the L-shaped plate.

[0015] By adopting the above technical solution, the rubber pad is made of rubber material, and its surface has a large friction coefficient. The rubber pad increases the friction between the bottom of the horizontal part of the L-shaped plate and the track surface, reducing the probability of displacement of the L-shaped plate. In addition, the setting of the rubber pad also reduces the wear on the bottom of the horizontal part of the L-shaped plate.

[0016] Furthermore, the mounting plate is rotatably connected to the inner wall of the mounting opening.

[0017] By adopting the above technical solution, the rotatably connected mounting plate allows the mounting plate and the projector laser to be rotated and folded away when no measurement is required, making the device easy to carry.

[0018] Furthermore, a first magnetic block is embedded in the inner wall of the installation opening, and a second magnetic block that is magnetically attracted to the first magnetic block is embedded in the side wall of the installation plate.

[0019] By adopting the above technical solution, the first magnetic block and the second magnetic block are magnetically attracted to each other, and the mounting plate is adsorbed and fixed in the mounting opening, thereby reducing the probability of the mounting plate automatically rotating during carrying.

[0020] Furthermore, a bubble level is provided on the upper surface of the L-shaped plate.

[0021] By adopting the above technical solution, the staff can observe the horizontality of the L-shaped plate through the bubble level, which is convenient for leveling the L-shaped plate and the projector laser.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. In this application, when the track needs to be measured, the staff places the L-shaped plate on the track and presses the L-shaped plate against the track. The staff rotates the first screw rod through the star-shaped handle. Since the first screw rod is threadedly connected to the slider, and the slider is slidably connected to the inner wall of the slide groove, the slider drives the fixed plate to move along the axial direction of the first screw rod, so that the side wall of the fixed plate presses against the side wall of the track. The track is then measured by the projector laser, which reduces the probability of the L-shaped plate shaking or even falling off during measurement, affecting the measurement accuracy.

[0024] 2. In this application, after the fixed plate is driven to press against the side wall of the track by the driving assembly, the staff rotates the second screw by the rotating block. Since the second screw is threadedly connected to the limit plate, the limit plate is slidingly connected to the inner wall of the adjustment groove, thereby causing the limit plate to move axially along the second screw, causing the limit plate to press upward against the track, further enhancing the stability of the device;

[0025] 3. In this application, after the fixing plate is pressed against the side wall of the track, the staff needs to tighten the limiting nut so that the side wall of the limiting nut is pressed against the side wall of the L-shaped plate, thereby limiting the rotation of the first screw and reducing the probability of the fixing plate loosening due to the rotation of the first screw.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] like Figure 1-3 As shown, an embodiment of the present application discloses a new type of railway square, including an L-shaped plate 1, a mounting plate 2, a projector laser 3, a fixing plate 4 and a driving assembly 5.

[0032] The L-shaped plate 1 is a plate-like structure with an L-shaped cross-section. It has a mounting opening 11, and a slide groove 12 is defined at the bottom of the horizontal portion of the L-shaped plate 1. The mounting plate 2 is a plate-like structure and is positioned within the mounting opening 11. The projector laser 3, a projector laser 3 commonly used in the prior art and suitable for this embodiment, is positioned on the upper surface of the mounting plate 2. The fixing plate 4 is a rectangular plate-like structure and is slidably connected to the bottom of the horizontal portion of the L-shaped plate 1.

[0033] The drive assembly 5 is mounted on the L-shaped plate 1 and is used to drive the fixed plate 4 to move. The drive assembly 5 includes a slider 51, a first screw 52, ​​and a star-shaped handle 53. The slider 51 is a rectangular parallelepiped structure fixed to the upper surface of the fixed plate 4 and slidably connected to the inner wall of the chute 12. The first screw 52 is a horizontally arranged rod-like structure that extends through the side wall of the L-shaped plate 1 and is rotatably connected. One end of the first screw 52 is rotatably connected to the inner wall of the chute 12. The first screw 52 extends through the side wall of the slider 51 and is threadedly connected to the slider 51. The star-shaped handle 53 is fixed to the end of the first screw 52 away from the slider 51, and the axis of the star handle 53 coincides with the axis of the first screw 52.

[0034] When the track needs to be measured, the staff places the L-shaped plate 1 on the track and presses the L-shaped plate 1 against the track, and rotates the first screw rod through the star-shaped handle 53. Since the first screw rod is threadedly connected to the slider 51, the slider 51 is slidingly connected to the inner wall of the slide groove 12, so that the slider 51 drives the fixed plate 4 to move axially along the first screw rod, so that the side wall of the fixed plate 4 presses against the side wall of the track, and then the track is measured by the projector laser 3, which reduces the probability of the L-shaped plate 1 shaking or even falling off during measurement, affecting the measurement accuracy.

[0035] In order to further enhance the stability of the device, an adjustment slot 41 is provided on the side wall of the fixed plate 4 near the vertical portion of the L-shaped plate 1. A reinforcement assembly 6 is installed on the fixed plate 4, and the reinforcement assembly 6 includes a limit plate 61, a second screw 62, and a rotating block 63. The limit plate 61 is a rectangular plate-like structure, and the limit plate 61 is slidingly connected to the inner wall of the adjustment slot 41. The second screw 62 is a vertically arranged rod-like structure, and the second screw 62 is arranged on the fixed plate 4 and is rotatably connected. The upper end of the second screw 62 is rotatably connected to the inner top wall of the adjustment slot 41, and the second screw 62 passes through the limit plate 61 and is threadedly connected to the limit plate 61. The rotating block 63 is a round block-shaped structure, and the rotating block 63 is fixed to the lower end of the second screw 62, and the axis of the rotating block 63 coincides with the axis of the second screw 62. After the fixed plate 4 is driven to press against the side wall of the track through the driving assembly 5, the staff rotates the second screw 62 through the rotating block 63. Since the second screw 62 is threadedly connected to the limit plate 61, the limit plate 61 is slidingly connected to the inner wall of the adjustment groove 41, so that the limit plate 61 moves axially along the second screw, so that the limit plate 61 presses upward against the track, thereby further enhancing the stability of the device.

[0036] To reduce the possibility of the fixing plate 4 loosening due to the rotation of the first screw 52, ​​a limiting assembly 7 is mounted on the first screw 52 to limit its rotation. The limiting assembly 7 comprises a limiting nut 71 and an annular washer 72. The limiting nut 71 is sleeved onto the first screw 52 and threadedly connected thereto. The axis of the limiting nut 71 coincides with the axis of the first screw 52. The annular washer 72 is sleeved onto the first screw 52 and positioned between the limiting nut 71 and the L-shaped plate 1. After the fixing plate 4 is secured against the sidewall of the track, the operator tightens the limiting nut 71 so that the sidewall of the limiting nut 71 mates with the sidewall of the L-shaped plate 1 and abuts against the annular washer 72, thereby limiting the rotation of the first screw 52 and reducing the possibility of the fixing plate 4 loosening due to the rotation of the first screw 52. The annular washer 72 is made of a rubber material with high friction, which increases the friction between the limiting nut 71 and the L-shaped plate 1, thereby enhancing the retaining effect on the first screw 52.

[0037] In order to reduce the probability of displacement of the L-shaped plate 1, a plurality of rubber pads 8 are fixed to the bottom of the horizontal portion of the L-shaped plate 1. The rubber pads 8 are made of rubber material and have a large friction coefficient on their surface. The rubber pads 8 increase the friction between the bottom of the horizontal portion of the L-shaped plate 1 and the track surface, thereby reducing the probability of displacement of the L-shaped plate 1. In addition, the provision of the rubber pads 8 also reduces the wear on the bottom of the horizontal portion of the L-shaped plate 1.

[0038] In order to facilitate carrying the device, the mounting plate 2 is rotatably connected to the inner wall of the mounting opening 11. The rotatably connected mounting plate 2 allows the mounting plate 2 and the projector laser 3 to be rotated and retracted when no measurement is required, thereby facilitating carrying the device.

[0039] In order to reduce the probability of the mounting plate 2 automatically rotating during carrying, a first magnetic block 13 is embedded in the inner wall of the mounting opening 11, and a second magnetic block 21 that is magnetically attracted to the first magnetic block 13 is embedded in the side wall of the mounting plate 2. The first magnetic block 13 and the second magnetic block 21 are magnetically attracted to each other, and the mounting plate 2 is adsorbed and fixed in the mounting opening 11, thereby reducing the probability of the mounting plate 2 automatically rotating during carrying.

[0040] In order to facilitate the leveling of the L-shaped plate 1 and the projector laser 3, a bubble level 9 is provided on the upper surface of the L-shaped plate 1. The staff can observe the horizontality of the L-shaped plate 1 through the bubble level 9, thereby facilitating the leveling of the L-shaped plate 1 and the projector laser 3.

[0041] The operating principle of a new type of railway ruler in this embodiment is as follows: when it is necessary to measure the track, the staff places the L-shaped plate 1 on the track and makes the L-shaped plate 1 press against the track, and rotates the first screw rod through the star-shaped handle 53. Since the first screw rod is threadedly connected to the slider 51, the slider 51 is slidingly connected to the inner wall of the slide groove 12, so that the slider 51 drives the fixed plate 4 to move along the axial direction of the first screw rod, so that the side wall of the fixed plate 4 presses against the side wall of the track, and then the track is measured by the projector laser 3, which reduces the probability of the L-shaped plate 1 shaking or even falling off during measurement, affecting the measurement accuracy.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
