Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a portable device for disassembling and assembling a fast spring clip and a spring clip cap. Background Art

[0002] In the rail transit industry, the coordination of the Fastclip and the clip cap is a critical component of the fastening system. During the production process, specialized equipment is often required to install the clip cap to ensure a tight and secure fit between the clip and the clip cap.

[0003] These specialized devices are often designed for high precision and efficiency, enabling accurate installation of the clip cap onto the clip during pre-assembly. However, these devices are often large and difficult to port, which limits their use. This is particularly true in field operations, where limited space and complex environments make these large devices difficult to use.

[0004] When track maintenance is required, on-site operating space is often limited, and large equipment is difficult to carry and use. In these situations, maintenance personnel often rely on simple tools, such as blunt instruments, to remove and install the spring clip caps by hammering. This method is not only inefficient but also unsafe. The hammering process significantly damages the spring clip caps and the spring clips, compromising their effectiveness.

[0005] Furthermore, due to the complexity and uncertainty of on-site working environments, using blunt instruments for striking may also lead to other potential safety hazards. For example, sparks generated during striking could cause dangerous situations such as fire or explosion; at the same time, excessive striking force could cause unnecessary damage to the track structure.

[0006] Therefore, to address the issue of clip cap removal and installation in rail transit fastclip fasteners, there is an urgent need for a portable, efficient, and safe removal and installation device. This device should be adaptable to the specific working environment, meet the needs of maintenance personnel for clip cap removal and installation, and ensure safety and efficiency during operation.

[0016] The beneficial effects of the present invention are specifically reflected in the following aspects:

[0017] (1) The disassembly and assembly equipment is centered around the spring clip disassembly and assembly base, with cleverly designed positioning slots and disassembly parts, enabling efficient disassembly and assembly of the fast spring clip and the spring clip cap.

In summary, this portable fast spring clip and spring cap disassembly and assembly equipment is undoubtedly a major breakthrough in the field of track accessory disassembly and assembly technology. It not only solves many pain points and problems in traditional disassembly and assembly methods, but also provides a strong guarantee for the efficiency and safety of track maintenance work.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1:

[0036] like Figure 1-10 As shown, a portable fast clip and clip cap disassembly and assembly device includes a clip disassembly and assembly base. A positioning groove 5 for positioning the fast clip is designed on the clip disassembly and assembly base 1. A disassembly member 3 for disassembling the clip cap is installed at a position corresponding to the positioning groove on the clip disassembly and assembly base. The middle portion of the disassembly member is rotatably mounted on the clip disassembly and assembly base via a rotating shaft 6. An installation claw 302 and a disassembly claw 301 are relatively mounted on the lower end of the disassembly member. A force-applying portion is installed on the upper end of the disassembly member, which drives the installation claw or the disassembly claw to rotate around the axis. The installation claw 302 is used to install the clip cap 8 on the fast clip 7 in the positioning groove, and the disassembly claw is used to remove the clip cap from the fast clip in the positioning groove.

[0037] The force-applying portion is equipped with an extension rod 303 for extending its power arm, thereby increasing its power arm and reducing the operator's labor intensity. According to the principle of leverage, the longer power arm enables the operator to apply greater thrust to the spring clip cap while using the same amount of force, making it easier to remove and install the spring clip cap. This design significantly reduces the operator's labor intensity and improves work efficiency.

[0038] As a preferred embodiment, the installation claw 302 and removal claw 301 are asymmetrically designed, with inwardly curved bends 304 at their ends, enabling more precise positioning and operation when performing their respective functions. The curved bends not only increase the contact area and friction between the claws and the spring clip cap, but also make the assembly and disassembly process smoother and more controllable. This design effectively prevents damage to the spring clip cap or the track structure caused by improper operation, improving the precision and safety of assembly and disassembly.

[0039] As a preferred embodiment, an extension plate assembly 4 is further installed on the side of the spring clip disassembly and assembly base 1 close to the force application direction. The extension plate assembly 4 includes an extension base plate 401 and a reinforcement vertical plate 402. A reinforcement connecting plate 403 is relatively installed between the extension base plate and the reinforcement vertical plate. A triangular support structure is formed between the extension base plate, the reinforcement vertical plate and the reinforcement connecting plate. The position of the extension plate assembly is replaced according to the operation scenario. To install the fast spring clip cap, the extension plate assembly needs to be installed behind the spring clip disassembly and assembly base; to remove the fast spring clip cap, the extension plate assembly needs to be installed in front of the spring clip disassembly and assembly base; when the fast spring clip cap is disassembled, since it uses the lever principle and the hook is hinged, the force at the input end is not a horizontal force, and an oblique upward component force will be applied to the spring clip disassembly and assembly base. Adding the extension plate assembly can effectively prevent the spring clip disassembly and assembly base from being affected by its component force.

[0040] As a preferred embodiment, a cover plate 2 is detachably mounted on the upper part of the spring clip disassembly base 1, and a positioning groove 3 is formed between the spring clip disassembly base and the cover plate. The cover plate 3 limits the fast spring clip up and down, and the spring clip disassembly base limits the fast spring clip front and back.

[0041] As a form of the cover plate, footrests 9 are symmetrically installed on both sides of the cover plate 2 to prevent the equipment from tilting during operation.

[0042] like Figure 9 As one of the positioning forms, there are two limit points on the spring clip disassembly and assembly base 1, corresponding to ⑨ and ⑩ in the figure, which match the inner arc of the end of the middle toe of the fast spring clip.

[0043] like Figure 8 As another form of positioning, there are four positioning points on the spring clip assembly and disassembly base, corresponding to ①, ②, ③, and ④ in the figure, which correspond to the end of the middle toe of the fast spring clip and the front end of the toes on both sides of the fast spring clip respectively.

[0044] This disassembly and assembly device primarily consists of a clip assembly base, a positioning slot, a disassembly unit, installation claws, removal claws, and a force-applying unit. The clip assembly base serves as the supporting structure for the entire device. It features positioning slots for precisely positioning the fast clip, ensuring accuracy and stability during assembly and disassembly. The disassembly unit is the core component of the device. Its center pivots on a shaft mounted on the clip assembly base, enabling flexible rotational operation. The disassembly unit's lower end features installation and removal claws, respectively used for installing and removing the clip cap. The installation claws precisely attach the clip cap to the fast clip in the positioning slot, while the removal claws easily remove it from the positioning slot. The force-applying unit, located at the upper end of the disassembly unit, amplifies the force applied by the operator. By leveraging the force-applying unit, the operator only needs to apply minimal force to quickly install and remove the clip cap. This not only effectively reduces labor intensity and prevents violent construction, but also significantly improves work safety and efficiency. Furthermore, the device boasts a simple structure and easy portability. Its compact and rational overall design makes it easy to carry and store, making it ideal for use on track maintenance sites. Whether on busy mainline railways or remote mountainous areas, this disassembly and assembly equipment demonstrates its unique advantages, providing strong support for track maintenance personnel.

[0045] The implementation method of the disassembly and assembly device in this embodiment is as follows:

[0046] (1) Confirm whether you are installing or removing the fast clip cap. To install the fast clip cap, install the extension plate behind the clip assembly base; to remove the fast clip cap, install the extension plate in front of the clip assembly base.

[0047] (2) After the fast spring clip is fixed, the rotation direction of the extension rod is selected according to the installation and removal of the spring clip cap. After confirming that it is correct, the extension rod is pulled and the spring clip cap moves back and forth to realize the installation and removal of the spring clip cap of the fast spring clip.

[0048] (3) After the spring clip cap is disassembled and assembled, the spring clip is taken out and the entire operation process is completed; the fast spring clip is fixed using the spring clip disassembly base and cover plate.

[0049] (4) After the fast spring clip is fixed, the rotation direction of the extension rod is selected according to the installation and removal of the spring clip cap. After confirming that it is correct, the extension rod is pulled and the spring clip cap moves back and forth to realize the installation and removal of the spring clip cap of the fast spring clip.

[0050] (5) After the spring bar cap is disassembled and assembled, the spring bar is taken out and the entire operation process is completed.

[0051] In order to further prove the operability of the above equipment, the following feasibility analysis is made: Analysis of the overall stability of the equipment:

[0052] When removing and installing the clip cap, the fast clip uses the lever principle and the hook is hinged. The input force is not horizontal, and will exert an upward component on the clip removal base. Adding an extension plate can effectively prevent the clip removal base from being affected by this component force.

[0053] The cover structure can also be changed to limit the displacement of the base for disassembly and assembly of the spring bar through the cover, and pedals can be added to prevent the equipment from tilting during operation by stepping on it. When disassembling and assembling, you only need to change the direction of the cover.

[0054] 2. Design of the fixed structure of the spring bar:

[0055] like Figure 8 、 9 10. When the fast clip is disassembling and installing the clip cap, the fast clip needs to be fixed. The clip disassembling base designed in this invention can effectively prevent the fast clip from being displaced in the horizontal direction during the disassembly and installation of the clip cap. During installation, the fast clip is fixed through fixing points ③, ④, ⑤, ⑥, ⑦, and ⑧. During disassembly, the fast clip is fixed through fixing points ①, ②, ⑤, ⑥, ⑦, and ⑧. The fixing points of the clip disassembly base can also be changed to fixing points ⑨ and ⑩, and the clip can be fixed through the inner arc at the end of the middle toe of the clip.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
