Description

Homemade Portable Nail Ruler Technical Field

[0001] This utility model relates to the field of measuring devices, specifically to a self-made portable track gauge. Background Technology

[0002] Rail transport is the most important auxiliary transportation method in coal mines. High-quality, high-standard track anchoring directly ensures the smooth and normal operation of rail transport, effectively preventing derailments and handling the safety risks associated with them. Track gauges are commonly used during track anchoring to measure the spacing and level of the pre-anchored rails on both sides.

[0003] Existing track gauge structures, such as the utility model patent with application number CN202420417764.X, disclose a track gauge for track maintenance, including a toothed rod with distance scale lines on its upper surface. A fixed measuring head is fixedly connected to one side of the bottom of the toothed rod. An elongated cavity is formed inside one end of the toothed rod, and a slider is slidably installed inside the elongated cavity. A movable measuring head is fixedly connected to the lower end of the slider, and a handle is fixedly connected to the upper end of the slider. When measuring the distance between two rails, the fixed measuring head is placed against the inside of one rail, and the handle is held to move the movable measuring head closer to the inside of the other rail. The distance between the two rails is obtained by reading the distance scale lines indicated by two first pointers.

[0004] However, the aforementioned gauge does not have telescopic or folding functions, and its length makes it inconvenient to carry. Summary of the Invention

[0005] The purpose of this invention is to provide a self-made portable nail ruler that is telescopic and adjustable for easy carrying, thereby addressing the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A homemade portable track gauge includes a first and a second gauge body positioned horizontally. Both the first and second gauge bodies are hollow square tubes. One end of the second gauge body is slidably fitted inside one end of the first gauge body. A locking component is provided between the first and second gauge bodies to restrict the sliding of the second gauge body along the first gauge body. Measuring plates for abutting against the inner side of the track are fixedly installed at the bottom of the first gauge body and at the bottom of the end of the second gauge body extending outside the first gauge body. A first pad for fitting against the top of the track is fixedly installed at the bottom of the first gauge body, and a second pad for fitting against the top of the track is fixedly installed at the bottom of the end of the second gauge body extending outside the first gauge body. The bottom of the first pad and the bottom of the second pad are flush. A level is fixedly installed at the top of the first gauge body.

[0008] As a further improvement, the inner wall of the first ruler body is provided with a guide protrusion extending along its length direction, and the outer wall of the second ruler body is provided with a strip groove that matches the guide protrusion.

[0009] As a further improvement, the locking component includes a screw that is fixedly mounted on the second ruler and extends perpendicular to its length direction. The side wall of the first ruler is provided with a strip-shaped slot through which the screw passes. The strip-shaped slot extends along the length direction of the first ruler. A wing nut for pressing against the outer wall of the first ruler is screwed onto the screw.

[0010] As a further improvement, a sliding pin is fixedly installed on the second ruler body, extending perpendicular to its length direction, and a strip hole matching the sliding pin is provided on the side wall of the first ruler body, the strip hole extending along the length direction of the first ruler body.

[0011] As a further improvement, a lifting handle is movably mounted on one end of the second ruler extending outside the first ruler. One end of the lifting handle is rotatably mounted on the second ruler via a damping shaft, and both the lifting handle and the second ruler are perpendicular to the axis of the damping shaft. A first handle is fixedly mounted on the end of the lifting handle away from the damping shaft, and a second handle is fixedly mounted on the end of the first ruler away from the second ruler. When the sliding pin moves to the end of the strip hole away from the second ruler and the lifting handle rotates towards the first ruler to a horizontal state, the first handle and the second handle engage to form a third handle.

[0012] As a further improvement, a limiting post matching the lifting handle is fixedly installed on the second ruler body. When the lifting handle is rotated upward to a vertical position, the limiting post abuts against one side of the lifting handle and prevents the lifting handle from rotating away from the first ruler body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. After the nail track ruler is used up, the wing nut is loosened to release the restriction on the second ruler body. Then, the second ruler body is slid to the left along the first ruler body to allow more of the second ruler body to be retracted into the first ruler body, thereby reducing the overall space occupied by the nail track ruler. Then, the lifting handle is rotated to the left to a horizontal position to retract it. The staff can carry the nail track by the third handle composed of the first handle and the second handle, which has the advantages of being convenient to carry and store.

[0015] 2. When using a track gauge to measure the track spacing, the lifting handle can be rotated upwards to a vertical position and unfolded. The right side of the lifting handle is held in place by the limiting post. The operator can lift the track gauge by the first handle and move it to different positions on the track for measurement. This eliminates the need for the operator to frequently bend over to pick up and put down the track gauge during measurement, making it convenient to use. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As shown in Figures 1 to 3, a homemade portable track gauge includes a first gauge body 1 and a second gauge body 2 arranged horizontally. Both the first gauge body 1 and the second gauge body 2 are hollow square tubes. The left end of the second gauge body 2 is slidably fitted inside the right end of the first gauge body 1. A locking component is provided between the first gauge body 1 and the second gauge body 2 to restrict the sliding of the second gauge body 2 along the first gauge body 1. A measuring plate 3 for abutting against the inside of the track is welded or fixed by bolts to the bottom left end of the first gauge body 1 and the bottom right end of the second gauge body 2. The measuring plate 3 is arranged vertically.

[0023] In use, firstly, according to the preset width of the track, slide the second ruler 2 along the first ruler 1 to adjust the distance between the outer sides of the two measuring plates 3. In this embodiment, the top of the second ruler 2 is marked with a scale so that the distance between the outer sides of the two measuring plates 3 can be confirmed according to the corresponding scale on the right end of the first ruler 1. After adjusting the distance between the outer sides of the two measuring plates 3 to the correct position, adjust the locking component to restrict the sliding of the second ruler 2 along the first ruler 1, so that the distance between the outer sides of the two measuring plates 3 remains fixed. After completing the above adjustment, the track spacing can be measured. The two measuring plates 3 are used to confirm whether the track spacing meets the requirements. Specifically: if the two measuring plates 3 can be inserted between the two tracks, the spacing between the two tracks meets the requirements; if the two measuring plates 3 cannot be inserted smoothly between the two tracks, the spacing between the two tracks is too narrow; if there is still a large lateral movement margin after the two measuring plates 3 are inserted between the two tracks, the spacing between the two tracks is too wide.

[0024] The bottom left end of the first ruler body 1 is welded or fixed with bolts to a first pad 4 for attaching to the top of the track. The bottom right end of the second ruler body 2 is welded or fixed with bolts to a second pad 5 for attaching to the top of the track. The bottom of the first pad 4 is flush with the bottom of the second pad 5. The first pad 4 and the second pad 5 are located on the outside of the two measuring plates 3 respectively. The top of the first ruler body 1 is fixed with screws or glued to a level 6.

[0025] After inserting the two measuring plates 3 between the two tracks, the two tracks support the first pad 4 and the second pad 5 respectively. Since the bottom of the first pad 4 is flush with the bottom of the second pad 5, the levelness between the two tracks can be confirmed by observing the level 6.

[0026] The inner wall of the first ruler 1 is integrally formed with a guide protrusion 7 extending along its length direction, and the outer wall of the second ruler 2 is provided with a strip groove 8 that matches the guide protrusion 7, which can improve the stability of the second ruler 2 sliding along the first ruler 1.

[0027] The locking component includes a screw 9 welded to the bottom of the second ruler 2 and extending perpendicular to its length direction. The bottom wall of the first ruler 1 is provided with a strip-shaped slot 10 through which the screw 9 passes. The strip-shaped slot 10 extends along the length direction of the first ruler 1 and is open at the right end. A wing nut 11 for pressing against the outer wall of the first ruler 1 is screwed onto the screw 9.

[0028] After adjusting the distance between the outer sides of the two measuring plates 3 by sliding the second ruler 2 along the first ruler 1, tighten the wing nut 11 to make it press against the bottom wall of the first ruler 1, thereby restricting the sliding of the second ruler 2 along the first ruler 1 and keeping the distance between the outer sides of the two measuring plates 3 fixed. When the track gauge is finished, loosen the wing nut 11 to remove it from the bottom wall of the first ruler 1, thereby releasing the restriction on the second ruler 2. Then, more of the second ruler 2 can be retracted to the left into the first ruler 1, thereby reducing the overall space occupied by the track gauge and making it more convenient to carry and store. In addition, the lower end of the screw 9 in this embodiment is also equipped with a stop bar, which is located below the wing nut 11, to prevent the wing nut 11 from completely detaching from the screw 9 and being lost when it is loosened.

[0029] The front and rear sides of the second ruler 2 are respectively fitted with sliding pins 12 extending perpendicular to its length direction. The front and rear side walls of the first ruler 1 are respectively provided with strip holes 13 that match the sliding pins 12. The strip holes 13 extend along the length direction of the first ruler 1. When the second ruler 2 slides along the first ruler 1, it can drive the sliding pins 12 to slide along the strip holes 13. The strip holes 13 can limit the sliding stroke of the second ruler 2 and prevent the second ruler 2 from completely separating from the first ruler 1.

[0030] The right end of the second ruler 2 is movably mounted with two lifting handles 14 on the front and rear sides respectively. The distance between the two lifting handles 14 is greater than the width of the first ruler 1. One end of the lifting handle 14 is rotatably mounted on the second ruler 2 through a damping shaft 15. The axis of the damping shaft 15 extends front and rear. Both the lifting handle 14 and the second ruler 2 are perpendicular to the axis of the damping shaft 15. The ends of the two lifting handles 14 away from the damping shaft 15 are fixedly mounted with a first handle 16 by screws. The left end of the first ruler 1 is fixedly mounted with a second handle 17 by screws. When the sliding pin 12 moves to the left end of the strip hole 13 and the lifting handle 14 rotates to the left to a horizontal state, the first handle 16 fits against the upper side of the second handle 17, and the first handle 16 and the second handle 17 are interlocked to form a third handle 18.

[0031] Specifically, after the nail track ruler is used up, loosen the wing nut 11 to disengage it from the bottom wall of the first ruler body 1, and then slide the second ruler body 2 to the left along the first ruler body 1 to retract more of the second ruler body 2 into the first ruler body 1 until the second ruler body 2 drives the sliding pin 12 to move to the left end of the strip hole 13. Then, turn the lifting handle 14 to the left to a horizontal position to retract it. At the same time, the lifting handle 14 drives the first handle 16 to adhere to the upper side of the second handle 17, as shown in Figure 3. The worker can carry the nail track by holding the third handle 18, which is composed of the first handle 16 and the second handle 17.

[0032] The top of the second ruler body 2 is fixed with two upright plates arranged opposite each other. On the side of the two upright plates that are far apart from each other, a limiting post 19 that matches the corresponding lifting handle 14 is welded. The limiting post 19 is located on the rotation trajectory of the corresponding lifting handle 14. When the lifting handle 14 is rotated upward to the vertical position and the worker lifts the nail track ruler by holding the first handle 16, the limiting post 19 abuts against the right side of the corresponding lifting handle 14 and prevents the lifting handle 14 from continuing to rotate to the right relative to the second ruler body 2.

[0033] When using a track gauge to measure the track spacing, the lifting handle 14 can be rotated upwards to a vertical position and unfolded. The right side of the lifting handle 14 is held in place by the limiting post 19, as shown in Figure 1. The operator can lift the track gauge by the first handle 16 and move it to different positions on the track for measurement, so that the operator does not need to frequently bend over to pick up and put down the track gauge during the measurement operation.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
