Description

Technical Field

[0001] This invention relates to the field of railway bolt protection technology, and in particular to a railway rail protection component. Background Technology

[0002] Railway bolts (also called railway fastener bolts or track bolts) are key components in railway track systems, primarily used to connect railway tracks, sleepers, track slabs, and other components to ensure the track's fixation and stability. Protective grease is a protective lubricant used on metal components such as railway bolts; its main function is to prevent bolts and other metal parts from corroding, rusting, or wearing in harsh environments.

[0003] Currently, there are two different packaging methods for protective grease for railway bolts. The first method involves pre-quantitatively filling the protective grease into the bushing (a component of railway fasteners) using standard iron drums. The advantage of this packaging method is that it ensures accurate quantification of the anti-corrosion grease. The second method involves packaging the protective grease in plastic drums, which can be used directly on-site and is suitable for manual application by on-site workers. However, this operation is very cumbersome and time-consuming, especially during large-scale construction projects.

[0004] Due to a lack of quantitative control, construction workers often cannot accurately control the amount of grease added each time, which may result in over- or under-addition. Excessive grease is not only wasteful but may also affect the protective effect on railway bolts; while insufficient grease will not fully exert its anti-corrosion function and will not effectively prevent the railway bolts from rusting or wearing. Therefore, this invention proposes a railway rail protection component to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a railway track protection component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rail protection component for protecting railway bolts in railway fasteners includes a component box. A rotating seat is rotatably connected to the upper side of the component box. The rotating seat has a sliding groove inside, and two sliders are slidably connected inside the groove. A clamping shaft is fixed to the lower end of each slider, located inside the component box. A filling seat is fixed to the front end of the component box. A clamping seat is rotatably connected to the front side of the filling seat. Each clamping seat has a placement groove on its inner side. A handle block is fixed to the upper end of the clamping seat, and a worm gear is fixed to the upper transition part of the clamping seat. A corresponding meshing worm wheel is provided on the outer side of the worm gear. A rotating seat second, rotatably connected to the component box, is provided below the worm wheel. A fixed clamping shaft is fixed to the lower side of the rotating seat second, and a clamping shaft second, rotatably connected to the rotating seat second, is provided on one side of the fixed clamping shaft.

[0007] A rail protection component further includes a filling component, which is used in conjunction with a component box. The filling component includes several tubular bags, each containing a casing bag filled with a measured amount of protective grease.

[0008] Preferably, the tubular bag has a tear-out section at the bottom, which can be torn open to open the bottom opening of the tubular bag, through which the casing bag inside the tubular bag slides out, and the placement groove is adapted to the shape of the tubular bag.

[0009] Preferably, a lever is fixed on the upper side of each of the two sliders in the groove, and a compression spring located in the groove is provided on the outer side of each of the two sliders. A handle is fixedly installed on one side of the upper part of the component box.

[0010] Preferably, a side cover is hinged to the rear side of the component box via a spring hinge, and a bottom cover is hinged to the side cover via a spring hinge. Both the side cover and the bottom cover cover the outside of the component box.

[0011] Preferably, the worm gear is rotatably connected to the component box, a ratchet is fixed on the lower side of the worm gear, a corresponding one-way wheel is provided on the outer side of the ratchet, and the one-way wheel is fixedly connected to the corresponding rotating seat below.

[0012] Preferably, the outer periphery of the one-way wheel is evenly provided with several tooth blocks corresponding to the ratchet. The tooth blocks are restricted by the rotation of the one-way wheel and can only rotate in one direction within a certain range of angles. A torsion spring is provided at the junction of the tooth blocks.

[0013] Preferably, a torsion spring is provided at the junction of the second clamping shaft, and a limit block is fixed at the lower end of both the second clamping shaft and the fixed clamping shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses pre-filled protective grease in sausage casing bags. The flexible material enables automatic rupture when the bolt is screwed in, ensuring precise control of the grease quantity and avoiding errors caused by manual filling. The tubular bag continuous design, combined with the tear-out structure, enables rapid positioning and release. The worm gear drive and ratchet one-way mechanism work together to ensure that each press of the handle only moves the tubular bag by one unit width, achieving precise filling of the grease bag compartment by compartment and preventing overfilling or underfilling. 2. The component box of this invention enables rapid loading of filling components through the opening and closing structure of the side cover and bottom cover. The clamping shaft group, together with the compression spring, automatically fixes the bag connecting component and guides it to the clamping shaft two to complete the positioning. The overall assembly process is simple and efficient. The coordinated action of holding the handle with one hand and pressing the hand block, combined with the one-way wheel limiting mechanism, allows the staff to complete continuous filling without complicated debugging, significantly reducing the intensity of operation. 3. The present invention features a double-fixed clamping shaft assembly consisting of a torsion spring and a limiting block, combined with the unidirectional transmission characteristics of a ratchet, ensuring no reverse displacement during the winding process of the tubular bag, preventing misalignment or accumulation of the grease bag, and the placement groove formed by the filling seat and the clamping seat is perfectly adapted to the shape of the tubular bag. The combination of the tear-out part and the casing bag material enables damage-free release, protecting the integrity of the components and ensuring smooth grease injection.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-8A rail protection component for protecting railway bolts in railway fasteners includes a component box 1. A rotating seat 2 is rotatably connected to the upper side of the component box 1. A sliding groove 6 is provided inside the rotating seat 2. Two sliders are slidably connected inside the sliding groove 6. A clamping shaft 5 located inside the component box 1 is fixed to the lower end of each slider. A lever 8 is fixed to the upper side of each slider inside the sliding groove 6, and a compression spring 7 located inside the sliding groove 6 is provided on the outer side of each slider. A handle 10 is fixedly installed on one side of the upper part of the component box 1. A filling seat 14 is fixed to the front end of the component box 1. A clamping seat 15 is rotatably connected to the front side of the filling seat 14. A placement groove 22 is provided inside the clamping seat 15. A rail protection component further includes a filling component 9, which works in conjunction with a component box 1 mechanism. The filling component 9 includes several tubular bags 901, each containing a casing bag 902 filled with a measured amount of protective grease. A tear-open portion 903 is provided at the bottom of each tubular bag 901; tearing the tear-open portion 903 opens the lower opening of the tubular bag 901, allowing the casing bag 902 to slide out through the lower opening. A placement groove 22 is adapted to the shape of the tubular bag 901. This filling component 9 dispenses a measured amount of protective grease. The grease is filled into a casing bag 902 and then packaged by several connected tubular bags 901. The filling component 9 of the connected bags, together with the specially designed component box 1, can greatly improve the filling of the protective grease in the sleeve. The casing bag 902 is made of a flexible and easily broken material. When the railway bolt is screwed into the corresponding sleeve, the casing bag 902 is squeezed and broken, without affecting the normal installation of the bolt. This filling component 9 solves the problem of inaccurate grease filling in traditional manual filling and greatly improves the filling efficiency of protective grease in combination with the component box 1 structure. A side cover 3 is hinged to the rear of component box 1 via a spring hinge. A bottom cover 4 is hinged to the side cover 3 via a spring hinge. Both the side cover 3 and the bottom cover 4 cover the outside of component box 1. When using this component box 1 mechanism, the side cover 3 and bottom cover 4 of component box 1 need to be opened to easily insert several bag-type filling components 9. One side of the bag-type filling component 9 is fixed between two clamping shafts 5. The two clamping shafts 5 are subjected to the elastic force of the two outer compression springs 7, causing the two clamping shafts 5 to clamp one side of the middle filling component 9. Simultaneously, the bag-type filling component 9... The component is wound inside the component box 1 until the component box 1 is full. The other side of the filling component 9 is guided to the clamping shaft 12 on the front outside of the component box 1. The clamping shaft 12 is opened by the limiting block 13, so that the other side of the bag filling component 9 is placed between the clamping shaft 12 and the fixed clamping shaft 11. The clamping shaft 12 is under the action of the torsion spring and works with the fixed clamping shaft 11 to firmly clamp the other side of the bag filling component 9. At this time, the internal assembly of the bag filling component 9 inside the component box 1 is completed, and the subsequent filling work of the inner casing bag 902 of the filling component 9 can be carried out. A handle block 16 is fixed to the upper end of the clamping seat 15, and a worm gear 17 is fixed to the upper end of the clamping seat 15. A worm wheel 18 is provided on the outer side of the worm gear 17. A rotating seat 20 is rotatably connected to the component box 1 on the lower side of the worm wheel 18. A fixed clamping shaft 11 is fixed to the lower side of the rotating seat 20. A clamping shaft 12 is rotatably connected to the rotating seat 20 on one side of the fixed clamping shaft 11. A torsion spring is provided at the rotating part of the clamping shaft 12, and a limit block 13 is fixed to the lower end of both the clamping shaft 12 and the fixed clamping shaft 11. The worm gear 18 is rotatably connected to the component box 1. A ratchet 21 is fixed to the lower side of the worm gear 18. A corresponding one-way wheel 19 is provided on the outer side of the ratchet 21. The one-way wheel 19 is fixedly connected to the corresponding rotating seat 20 below. Several tooth blocks corresponding to the ratchet 21 are evenly arranged on the outer periphery of the one-way wheel 19. The tooth blocks are restricted by the rotation of the one-way wheel 19 and can only rotate in one direction within a certain range of angles. A torsion spring is provided at the junction of the tooth blocks. When filling the protective grease inside the railway fastener sleeve, hold the handle 10 with one hand and support the component box 1 with the other hand, aligning the filling seat 14 with the filling point of the lower sleeve. Note the position: Press the clamping seat 15 connected by the hand block 16. The clamping seat 15 rotates open, and the worm gear 17 at its connecting part drives the worm wheel 18 meshing on the outside. The worm wheel 18 drives the ratchet 21 fixed on the lower side to rotate. The ratchet 21 drives the one-way wheel 19 to rotate in one direction at a certain angle through several tooth blocks. The one-way wheel 19 drives the rotating seat 20 structure fixed on the lower side to rotate at a certain angle. The rotating seat 20 and the two clamping shaft structures on the lower side drive the bag filling component 9 fixed on one side to wind. The rotation angle of the rotating seat 20 is just enough to cause the filling component 9 to be displaced by a distance of one tubular belt 901 width. Meanwhile, the clamping seat 15 connected to the handle block 16 rotates vertically. Due to the setting of the one-way wheel 19 and the ratchet 21, the ratchet 21 will not be driven by the one-way wheel 19 when it is driven to rotate. Therefore, the rotating seat 20 will not rotate. At this time, the tubular bag containing the casing bag 902 is located in the placement groove 22 between the filling seat 14 and the clamping seat 15. The worker tears open the lower opening of the tubular bag 901 through the lower tear part 903, so that the lower opening of the tubular bag 901 is open. At this time, the worker presses the clamping seat 15 connected to the handle block 16 again. The tubular bag 901, which is no longer restricted and has its lower end open, can not only be rolled up by the structure of the clamping shaft 2 12 rotating on one side, but also the casing bag 902 inside falls into the corresponding sleeve below, thereby completing the quantitative, precise and rapid filling of the protective oil.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
