[0030] In order to make the above-mentioned purpose, technical scheme and advantages of the present invention more clear and easy to understand, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments of the present invention described herein only constitute part of the embodiments of the present invention, which are only used to explain the present invention and do not constitute a limitation of the present invention. In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0031] Example 1

[0032] See also Figure 2 As shown, the present invention provides a portable tool for rapid installation of floating rail fasteners, including a force frame 2, the force frame 2 is arranged in an X shape through a movable pin 5, and its upper end is a pressurizing end and is equipped with a pressurizing device 1, and its lower end is a pressure-applying end and is equipped with a lateral force block 8, the floating rail fastener has an elastic body on both sides of its rail waist, and the lateral force block 8 is used to be clamped at both ends of the elastic body to pressurize or relieve pressure and separate the floating rail fastener.

[0033] like Figure 1 The figure is a schematic diagram of the operation of the floating rail fastener during pressurized installation in the prior art. Figure 1 In the installation process, the installation tool consists of a manual hydraulic pump, a pressure gauge, an oil pipe, an oil cylinder, and an installation fixture, wherein the installation fixture is composed of two C-shaped steel plates connected by 4 to 5 bolts. During the installation process, the various components must first be assembled into one, and then the two C-shaped steel plates must be positioned and fixed in the desired position by adjusting the nuts on the bolts. The entire assembly and positioning process is complicated and cumbersome, and when a group of floating rail fasteners is installed, the installation fixture must be manually disassembled and the installation tool must be moved to the next group of floating rail fasteners, and then the above assembly and positioning procedures must be repeated. Due to the heavy weight of components such as the C-shaped steel plate in the installation tool, it often requires two to three people to work together to complete the installation of the floating rail fasteners during the mobile operation.

[0034] In the present invention, by using an X-shaped force frame 2 as the installation fixture, not only the force structure of the installation fixture and its positioning and adjustment method are greatly optimized, but also the use of steel plates in the existing installation fixture is greatly reduced, so as to achieve a significant weight reduction effect. At the same time, due to the setting of the lateral force block 8, the pressing force transmitted from the pressure end can be evenly distributed from both ends to the floating rail fastener, that is, to ensure that the force frame 2 has a certain length of uniform distribution for the load requirement of the floating rail fastener, and at the same time ensure that the floating rail fastener is not easy to deviate during the installation process, which is equivalent to obtaining a substitution effect. Figure 1 The effect of the installed fixture on the distributed transmission of force.

[0035] Therefore, the portable tool for rapid installation of floating rail fasteners described in the present invention can significantly reduce the overall weight of the installation tool and improve the efficiency of rapid installation of floating rail fasteners.

[0036] Preferably, the pressurizing device 1 is a jack.

[0037] Specifically, by adopting an X-shaped force-adding frame 2 as the installation fixture, while greatly optimizing the force-bearing structure form and positioning and adjustment method of the installation fixture, the force-adding frame 2 can be used in conjunction with the common jacks on the market, that is, the pressure-adding device 1 can be a jack, thereby eliminating the need to purchase a dedicated hydraulic pump, which is beneficial to significantly save expensive expenses.

[0038] Preferably, the pressurizing end is provided with a mounting platform 3 adapted to the pressurizing device 1 .

[0039] Specifically, when in use, the pressurizing device 1 , such as a jack, can be placed on the mounting platform 3 to ensure that the pressurizing device 1 is not misplaced during use.

[0040] As one of the preferred embodiments of the present invention, a groove is provided on the mounting platform 3 , and the groove is adapted to fit the pressurizing device 1 .

[0041] Preferably, a connecting rod 4 is extended or welded below the mounting platform 3 , and the connecting rod 4 is vertically arranged downward and is used to abut against a rail.

[0042] For details, see Figure 1 Combined with Figure 2 As shown, when the floating rail fastener is installed, the height of the rail will be significantly higher than the force application surface of the lateral force block 8 (the force application surface can be a flat surface or a curved surface). After the installation tool is positioned on the floating rail fastener, the connecting rod 4 can abut against the rail to play a limiting role, and provide strong support for the installation platform 3 with the pressurizing device 1 installed in the vertical direction, thereby avoiding the unstable center of gravity of the force frame 2 that is easily caused by the pressurizing device 1 during the pressurizing operation, which is beneficial to ensure the installation quality of the floating rail fastener.

[0043] Preferably, the connecting rod 4 is also fixedly connected to the force frame 2 via the movable pin 5 .

[0044] Specifically, the pressurization pressure required for the installation of the floating rail fastener is about 40Mpa, so the strength of the installation tool is also required to be relatively high. The further fixed connection between the connecting rod 4 and the booster frame 2 is beneficial to improving the overall structural strength of the installation tool and further ensuring that the center of gravity of the booster frame 2 is stable during the entire pressurization operation.

[0045] Preferably, the connecting rod 4 abuts against the rail in a sliding or rolling manner through a moving device 7 installed at the lower end thereof.

[0046] As one of the preferred embodiments of the present invention, the moving device 7 is a roller.

[0047] Specifically, since the force structure form and positioning adjustment method of the installation fixture are greatly optimized, in the present invention, after the lateral force block 8 is depressurized and separated from the floating rail fastener, the installation tool can be moved by rolling the roller on the rail, that is, the installation tool does not need to be removed from the rail at all, and the overall movement of the installation tool can be directly achieved, so that only one person can easily complete the whole process of the floating rail fastener, thereby greatly improving the efficiency of the installation tool for the rapid installation of the floating rail fastener. Of course, it should be noted that although rolling is more labor-saving than other forms of movement such as sliding, the rolling direction of the roller must be consistent with the longitudinal direction of the rail when rolling.

[0048] Preferably, the moving device 7 is threadedly connected to the lower end of the connecting rod 4 through a screw rod 6 welded at the upper end thereof.

[0049] Specifically, through the further threaded connection setting of the screw rod 6, when the floating rail fastener is installed using the installation tool, the force application point of the floating rail fastener, that is, the force application surface of the lateral force block 8, can be appropriately adjusted in height according to the installation requirements, so as to improve the expansion adaptability of the installation tool while ensuring the installation quality of the floating rail fastener.

[0050] Example 2

[0051] This embodiment is a further optimization made on the basis of the first embodiment with respect to the size and material structure of the portable tool.

[0052] See also Figure 2 As shown, the material structure of the portable tool is as follows:

[0053] The force frame 2, the mounting platform 3, the connecting rod 4, and the transverse force block 8 are all made of stainless steel, the movable pin 5 is made of No. 35 steel, and the screw rod 6 is made of No. 45 steel.

[0054] Specifically, the above-mentioned material structure can further ensure the overall lightness and low cost of the installation tool on the basis of satisfying the respective relevant functional characteristics, and further improve the portability of the installation tool.

[0055] Preferably, the size structure of the portable tool satisfies any one of the following:

[0056] The cross-sections of the force-adding frame 2 and the connecting rod 4 are both solid circles with a diameter of 10 mm;

[0057] The force frame 2 is 1200 mm high, and the connecting rod 4 is 800 mm high;

[0058] The installation platform 3 is 200 mm long, 100 mm wide, and 10 mm high, and the groove formed thereon is 5 mm deep;

[0059] The aspect ratio of the screw 6 is 15;

[0060] The roller diameter is 30 mm;

[0061] The lateral force block 8 is 30 mm long, 20 mm wide and 10 mm high.

[0062] Specifically, the structural dimensions of the portable tool are closely related to the structural dimensions of the floating rail fastener, wherein the movable pin 5 can generally be a cylindrical pin. In view of the fact that the structural dimensions of the floating rail fastener in China have been basically standardized, when the size structure of the portable tool is roughly or even strictly adopted as the above size structure, its various performances, such as positioning and adjustment reliability, load distribution characteristics, wheel-rail movement characteristics, and the force-bearing structure form of the force frame 2 itself and its pressurization matching form with the pressurizing device 1, etc., will be optimal in terms of overall comprehensive performance.

[0063] Example 3

[0064] See also Figure 1-2 As shown, the present invention also provides a quick installation method based on a floating rail fastener, using a portable tool as described in any one of embodiments 1-2, the method comprising the following steps:

[0065] S1: placing the portable tool without the pressurizing device 1 directly above the floating rail fastener, and adjusting the height of the moving device 7 according to the force application point of the floating rail fastener;

[0066] S2: placing the pressurizing device 1 on the mounting platform 3;

[0067] S3: the pressure device 1 applies a load and transmits the load to the floating rail fastener to install and maintain the floating rail fastener;

[0068] S4: After the installation and adjustment of the floating rail fasteners are completed, the pressure of the pressurizing device 1 is unloaded;

[0069] S5: moving the portable tool to the next set of floating rail fasteners;

[0070] S6: Execute steps S3-S5 in a loop.

[0071] Specifically, usually, only steps S3-S5 need to be executed cyclically to continuously install and maintain the next set of floating rail fasteners in the mobile operation mode. During the cyclic execution of steps S3-S5, whether the height of the moving device 7 needs to be adjusted can be selectively set according to actual installation needs.

[0072] Preferably, after step S5 and before step S3, step S6 further includes the following specific steps:

[0073] S61: judging whether the height of the moving device 7 needs to be adjusted according to the force application point of the current floating rail fastener;

[0074] S62: If yes, adjust the height of the moving device 7 according to the force application point of the current floating rail fastener, and go to step S3; if no, directly execute step S3.

[0075] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
