Technical Field

[0001] This utility model relates to the field of railway track replacement technology, and in particular to a multi-directional elevation positioning device for sleeper replacement. Background Technology

[0002] Railway sleeper replacement is one of the main tasks of mechanized maintenance of railway lines. To carry out sleeper replacement, the ballast needs to be treated first. This is done by a road-rail dual-purpose excavator. Generally, during sleeper replacement operations on overhaul trains, the ballast is removed by a device integrated on the vehicle. Then, steel reinforcement templates are woven, the sleeper boxes are positioned, and then new sleepers are poured.

[0003] When locating the sleeper boxes, it is necessary to manually use a measuring ruler to measure the horizontal, left, right, front, back, and elevation of each sleeper box's pre-embedded position to determine its location and then mark it. This is very time-consuming and labor-intensive, reducing the efficiency of replacement and laying. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: when positioning the sleeper box, it is necessary to manually use a measuring ruler to measure the horizontal, left, right, front, back and elevation of the pre-embedded position of each sleeper box to determine its position and then mark it, which is very time-consuming and labor-intensive and reduces the efficiency of replacement and laying. Therefore, a multi-directional elevation positioning device for sleeper replacement is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The worm is rotatably connected to the side wall of the housing. The worm wheel is fixedly connected to the outer surface of the rotating rod, and the worm and the worm wheel are meshed together. Threads are formed at both ends of the rotating rod. Two connecting plates are threaded onto the rotating rod. Two measuring rods are fixedly connected to the ends of the two connecting plates away from the worm wheel. The measuring rods are slidably connected to the housing. Two measuring plates are fixedly connected to the ends of the two measuring rods away from the connecting plates.

[0008] Preferably, a slide rod is slidably connected to the inner side wall of the worm gear, and a push block is fixedly connected to the side wall of the slide rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A multi-directional elevation positioning device for sleeper replacement includes a housing 1 and a rotating rod 2. The rotating rod 2 is rotatably connected to the inner wall of the housing 1. Most of the main material of the internal mechanism is made of high-strength plastic, so it is lightweight and easy to carry.

[0023] The housing 1 is equipped with an adjustment mechanism, which includes a worm 3, a worm wheel 4, a connecting plate 5, a measuring rod 6, and a measuring plate 7. The worm 3 is rotatably connected to the side wall of the housing 1. The outer surface of the rotating rod 2 is fixedly connected to the worm wheel 4, and the worm 3 and the worm wheel 4 are meshed together. The two ends of the rotating rod 2 are respectively threaded. The two connecting plates 5 are respectively threaded onto the rotating rod 2. The two threads are in opposite directions, so when the rotating rod 2 rotates, the two connecting plates 5 will move closer to each other in the same direction or move away from each other. The two measuring rods 6 are respectively fixedly connected to the ends of the two connecting plates 5 away from the worm wheel 4. The measuring rods 6 are respectively slidably connected to the housing 1. The two measuring plates 7 are respectively fixedly connected to the ends of the two measuring rods 6 away from the connecting plates 5. The distances of the measuring plates 7 on both sides to the housing 1 are equal.

[0024] A sliding rod 8 is slidably connected to the inner wall of the worm gear 3. A push block 9 is fixedly connected to the side wall of the sliding rod 8. A marking block 10 is rotatably connected to the end of the sliding rod 8 away from the push block 9. A marking groove is opened on the side wall of the housing 1. The marking block 10 is slidably connected in the marking groove. The marking groove limits the marking block 10 to prevent the marking block 10 from rotating with the sliding rod 8. When the push block 9 is not pressed, the marking block 10 is stored in the housing 1 to avoid chalk leaving marks on the rail and causing errors when adjusting the position. Multiple installation grooves are opened at the end of the marking block 10 away from the sliding rod 8. Chalk can be placed in the installation grooves. The distance from the installation groove to the bottom surface of the measuring plate 7 corresponds to the distance between the measuring plate 7 and the upper surface of the sleeper box. The multiple installation grooves correspond to the top steel bar, the upper inclined surface, and the upper plane of the sleeper box, etc. Chalk can be installed at one of the positions as needed to mark the corresponding position. The marking block 10 is located on the center line of the housing 1.

[0025] A rotating ring 11 is fixedly connected to the outer surface of the worm gear 3. A return spring 14 is fixedly connected between the rotating ring 11 and the push block 9. The outer surface of the rotating ring 11 is provided with anti-slip texture to prevent slippage and facilitate the rotation of the rotating ring 11 and the worm gear 3.

[0026] Handles 12 are fixedly connected to both ends of the housing 1. Magnetic blocks 13 are fixedly connected to the four corners of the end of the housing 1 away from the handles 12. The magnetic blocks 13 can be attracted to the rails to facilitate the stability of the housing 1 during marking.

[0027] In this utility model, during use, the sleeper rails are first removed intermittently, along with the middle one of the three sleeper rails. Using the sleeper rail boxes on both sides as a reference, the new sleeper rail box positions are determined. Holding the handle 12, the rotating ring 11 on the housing 1 is rotated, causing the worm gear 3 to rotate. The rotation of the worm gear 3 causes the worm wheel 4 and the rotating rod 2 to rotate. The threads on the rotating rod 2 move the two connecting plates 5 away from each other. The connecting plates 5 move the measuring rod 6 and the measuring plate 7 away from each other. The measuring plate 7 is placed against the upper surface of the sleeper rail boxes on both sides. The rotating ring 11 is rotated so that the measuring plate 7 is placed between the two sleeper rail boxes. When the two measuring plates 7 are respectively against the side walls of the two sleeper rail boxes, the measuring plate 7 is placed on the upper surface of the two sleeper rail boxes. The housing 1 is placed against the rail. Under the magnetic attraction of the magnetic block 13, the housing 1 is attracted to the rail, ensuring the stability during marking.

[0028] The two sleeper boxes are almost perpendicular to the rails. Therefore, the center line of the housing 1 is the midpoint of the two sleeper boxes. The vertical distance from the measuring plate 7 to the sleeper box is the distance from the measuring plate 7 to the corresponding mounting groove in the marking block 10. At this time, pressing the push block 9 inward will drive the sliding rod 8 and the marking block 10 to move and compress the return spring 14. The marking block 10 will drive the chalk to move and mark on the rail. After releasing, under the elastic force of the return spring 14, the push block 9 will drive the sliding rod 8 and the marking block 10 to return to their original positions, thus determining the front and rear positions and elevation of the sleeper boxes. Since the sleeper boxes are buried directly below the rails and distributed with the rails as the center line, the position of the sleeper boxes is determined by the marking point and the rails themselves during construction.

[0029] The spacing between the sleeper boxes is almost the same. Even if there is a deviation, it can be adjusted by simply rotating the rotating ring 11 slightly, which is very simple and quick. Therefore, the adjusted measuring plate 7 is continuously mounted on the top of the two spaced sleeper boxes, and the pusher block 9 is pressed inward close to the rail to mark continuously. There is no need to calculate each measurement separately. The marking and measurement are completed simultaneously, which greatly reduces the time required for positioning, saves time and effort, and improves construction efficiency.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
