A rail bottom concrete troweling tool

Abstract

This utility model discloses a tool for plastering concrete under rails, including a base. A first electromagnet is installed inside the base via a sliding mechanism. A slot is formed inside the base, and a mounting post is installed on the inner wall of the slot via a reset mechanism. A mounting bracket is installed at the bottom of the base via a moving mechanism. The first electromagnet can fix the entire assembly in a designated position. The reset mechanism moves the mounting post away from the inner wall of the mounting slot, allowing the sliding block to move and thus adjust the position of the trowel. The reset mechanism also moves the mounting post into the inner wall of the mounting slot, limiting the sliding block and fixing the position of the base. The moving mechanism moves the trowel for plastering. Rotating a rotating rod drives a worm gear, which in turn drives a worm wheel, allowing the trowel to be raised or lowered via a lifting mechanism, thus adjusting the height of the trowel.

Description

Technical Field

[0001] This utility model relates to the field of concrete plastering technology for rail bases, and in particular to a tool for plastering concrete on rail bases. Background Technology

[0002] In railway engineering, track bottom concrete typically refers to the concrete layer laid at the bottom of the track structure, which serves to bear weight and transmit force. Depending on the type of track structure, its specific location and function vary. During construction, concrete is usually poured, and after pouring, a finishing tool is typically used to smooth the concrete surface.

[0003] When using troweling tools to smooth concrete, the space under the rails and fasteners is narrow and the lighting is insufficient, making it difficult to smooth the surface with ordinary concrete trowels. This results in low construction efficiency because workers need to bend over frequently to check the surface, which is labor-intensive and detrimental to the smoothing of concrete and the use of troweling tools. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tool for plastering concrete on the rail base, which solves the problems mentioned in the background.

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

[0006] A tool for finishing concrete on rail bases includes a base. A first electromagnet is mounted inside the base via a sliding mechanism. A slot is formed inside the base, and a mounting column is mounted on the inner wall of the slot via a reset mechanism. A mounting frame is mounted on the bottom of the base via a moving mechanism. A rotating rod is rotatably mounted on the inner wall of the mounting frame. A worm gear is fixedly mounted on the surface of the rotating rod, and a worm wheel is meshed on the surface of the worm gear. A connecting column is mounted on the inner wall of the worm wheel via a lifting mechanism. A second electromagnet is fixedly mounted at one end of the connecting column. A third electromagnet is located at the bottom of the second electromagnet, and a finishing mechanism is located at the bottom of the third electromagnet.

[0007] Preferably, the sliding mechanism includes a sliding groove formed inside the base, a sliding block slidably mounted on the inner wall of the sliding groove, an installation groove formed on one side of the sliding block, and one side of the sliding block and one side of the first electromagnet are fixedly mounted.

[0008] Preferably, the reset mechanism includes a sliding column slidably mounted on the inner wall of the slot, a sliding plate fixedly mounted on one end of the sliding column, a spring fixedly mounted on the inner wall of the slot, one end of the spring and one side of the sliding plate being fixedly mounted, and one side of the sliding plate and one end of the mounting column being fixedly mounted.

[0009] Preferably, the moving mechanism includes an electric slide rail fixedly installed at the bottom of the base, a slider slidably mounted on the surface of the electric slide rail, and the bottom of the slider and the top of the mounting bracket being fixedly installed.

[0010] Preferably, the lifting mechanism includes a lead screw fixedly installed on the inner wall of the worm gear, and a lifting plate is threaded onto the surface of the lead screw. The bottom of the lifting plate and one end of the connecting column are fixedly installed.

[0011] Preferably, the smearing mechanism includes a connecting rod fixedly installed at the bottom of the third electromagnet, and a smear blade is provided at one end of the connecting rod.

[0012] Preferably, a connecting frame is fixedly installed on one side of the base, and a wide-angle reflector is provided on one side of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This rail-bottom concrete plastering tool can be fixed in a designated position by a first electromagnet. A reset mechanism moves the mounting post away from the inner wall of the mounting groove, allowing the sliding block to move and adjust the position of the base, thereby adjusting the position of the trowel. After adjustment, the reset mechanism inserts the mounting post into the inner wall of the mounting groove, limiting the sliding block and fixing the position of the base. A moving mechanism moves the trowel, allowing for plastering. Rotating the rotating rod drives the worm gear, which in turn drives the worm wheel, raising and lowering the trowel via a lifting mechanism, allowing for height adjustment and facilitating plastering at specific heights. Disconnecting the second and third electromagnets allows the trowel to be removed. A new trowel is then installed by attaching the third and second electromagnets to the top and energizing them. This achieves the purpose of convenient plastering, eliminating the need for workers to frequently bend over. The structure is simple and easy to use. Attached Figure Description

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.

[0021] Example: Refer to Figure 1-5 This utility model provides a technical solution: a tool for plastering concrete under rails, comprising a base 1. A first electromagnet 5 is mounted inside the base 1 via a sliding mechanism. The sliding mechanism includes a groove 2 formed inside the base 1, a sliding block 3 slidably mounted on the inner wall of the groove 2, and an installation groove 4 on one side of the sliding block 3. One side of the sliding block 3 and one side of the first electromagnet 5 are fixedly mounted for easy adjustment of the first electromagnet 5. A connecting frame 24 is fixedly mounted on one side of the base 1, and a wide-angle reflector 25 is provided on one side of the connecting frame 24 to achieve blind-spot-free observation of the rail bottom. A slot 6 is formed inside the base 1, and the inner wall of the slot 6 is accessed by a reset mechanism. The mounting post 10 is installed, and the reset mechanism includes a sliding post 7 that is slidably installed on the inner wall of the slot 6. A sliding plate 9 is fixedly installed at one end of the sliding post 7. A spring 8 is fixedly installed on the inner wall of the slot 6. One end of the spring 8 is fixedly installed on one side of the sliding plate 9. One side of the sliding plate 9 is fixedly installed on one end of the mounting post 10, which facilitates the movement of the mounting post 10. The bottom of the base 1 is equipped with a mounting frame 13 through a moving mechanism. The moving mechanism includes an electric slide rail 11 fixedly installed on the bottom of the base 1. A slider 12 is slidably installed on the surface of the electric slide rail 11. The bottom of the slider 12 is fixedly installed on the top of the mounting frame 13, which facilitates the adjustment of the position of the mounting frame 13.

[0022] Specifically, a rotating rod 14 is rotatably mounted on the inner wall of the mounting bracket 13. A worm gear 15 is fixedly mounted on the surface of the rotating rod 14. A worm wheel 16 is meshed on the surface of the worm gear 15. A connecting column 19 is mounted on the inner wall of the worm wheel 16 via a lifting mechanism. The lifting mechanism includes a lead screw 17 fixedly mounted on the inner wall of the worm wheel 16. A lifting plate 18 is threaded onto the surface of the lead screw 17. The bottom of the lifting plate 18 and one end of the connecting column 19 are fixedly mounted to facilitate the lifting and lowering of the connecting column 19. A second electromagnet 20 is fixedly mounted on one end of the connecting column 19. A third electromagnet 21 is provided at the bottom of the second electromagnet 20. A troweling mechanism is provided at the bottom of the third electromagnet 21. The troweling mechanism includes a connecting rod 22 fixedly mounted on the bottom of the third electromagnet 21. A trowel 23 is provided at one end of the connecting rod 22. The entire assembly can be fixed in a designated position by the first electromagnet 5. The sliding block 3 can be slid by the reset mechanism driving the mounting column 10 away from the inner wall of the mounting groove 4. By moving the base 1, the position of the trowel 23 can be adjusted. After adjustment, the mounting post 10 is inserted into the inner wall of the mounting groove 4 by the reset mechanism, and the position of the base 1 is fixed by limiting the installation of the sliding block 3. The trowel 23 can be moved by the moving mechanism to perform surface troweling. By rotating the rotating rod 14, the worm gear 15 is rotated, and the worm gear 16 is rotated, which in turn drives the lifting mechanism to raise and lower the trowel 23, allowing the height of the trowel 23 to be adjusted for specific heights. By disconnecting the power to the second electromagnet 20 and the third electromagnet 21, the trowel 23 can be removed. Then, the third electromagnet 21 and the second electromagnet 20 are attached to the top of the new trowel 23 and energized, so that the trowel 23 can be installed. This achieves the purpose of facilitating surface troweling, eliminating the need for workers to frequently bend over, and is simple in structure and easy to use.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use: When using this rail-based concrete plastering tool, the entire assembly can be fixed in the designated position by the first electromagnet 5. By pulling the sliding column 7, the sliding plate 9 is moved, which in turn moves the mounting column 10, causing it to move away from the inner wall of the mounting groove 4. This allows the sliding block 3 to move, adjusting the position of the base 1 and consequently the position of the trowel 23. After adjustment, the spring 8 returns the slide plate 9 to its original position, moving it and causing the mounting column 10 to move. The mounting column 10 then inserts into the inner wall of the mounting groove 4, limiting the sliding block 3 and fixing the position of the base 1. The electric slide rail 11 moves the slider 12, which in turn moves the mounting frame 13, which in turn moves the trowel 23. The trowel 23 can be moved to perform surface finishing. Rotating the rotating rod 14 drives the worm gear 15 to rotate, which in turn drives the worm wheel 16 to rotate. The worm wheel 16 drives the lead screw 17 to rotate, which in turn drives the lifting plate 18 to rise and fall. The lifting plate 18 drives the connecting column 19 to rise and fall, which in turn drives the trowel 23 to rise and fall, allowing the height of the trowel 23 to be adjusted for specific surface finishing needs. By disconnecting the power to the second electromagnet 20 and the third electromagnet 21, the trowel 23 can be removed. Then, the third electromagnet 21 and the second electromagnet 20 are attached to the top of the new trowel 23 and energized, allowing the trowel 23 to be installed. This achieves the purpose of facilitating surface finishing, eliminating the need for workers to frequently bend over, and features a simple structure that is easy to use.
