[0029] As Figure 1 shown, the running rail fastener system of the railway passing platform in this embodiment is used to be installed on the frame body 200 of the railway passing platform to clamp the running rail 300. The fastener system includes a plurality of clamping assemblies 100. The plurality of clamping assemblies 100 are respectively arranged at opposite ends of the running rail 300 on the frame body 200. The clamping assembly 100 includes a mounting base 110 arranged on the frame body 200, a spring strip 120 arranged on the mounting base 110 for elastically clamping the running rail 300, a gauge block 130 inserted and matched with the mounting base 110 for horizontally abutting against the running rail 300, a height adjusting pad 140 abutting against the mounting base 110 and arranged below the running rail 300 to adjust the height of the running rail 300, and a connecting member 150 respectively connected to the spring strip 120 and the mounting base 110 for detachably connecting to the frame body 200 to assemble the spring strip 120 and the mounting base 110 on the frame body 200.

[0030] As Figure 1As shown in the figure, specifically, the railway passing platform running rail fastener system of the present utility model is used to be installed on the frame main body 200 of the railway passing platform to buckle the running rail 300. The fastener system arranges a plurality of buckling components 100 at the opposite ends of the running rail 300 on the frame main body 200 respectively. The buckling component 100 is detachably connected to the frame main body 200 through the connecting piece 150, so as to assemble the elastic strip 120 and the mounting base 110 on the frame main body 200. The mounting base 110 does not need to be buried in the frame main body 200. The elastic strip 120 is installed through the mounting base 110, and then the rail limb of the running rail 300 is elastically buckled through the elastic strip 120, so as to reduce the lateral force through elastic buffering, thereby extending the service life. Then, different specifications of gauge blocks 130 are inserted and matched with the mounting base 110 to adjust the gauge of the running rail 300 through different specifications of gauge blocks 130. Then, the height of the running rail 300 is adjusted through the shim plate 140 arranged under the running rail 300, and the shim plate 140 abuts against the mounting base 110, that is, the mounting base 110 abuts against and limits the shim plate 140 to improve the stability of the shim plate 140 after installation. Each component in the buckling component 100 cooperates with the mounting base 110, with good integrity, compact structure and reliable strength. Compared with the prior art, it has a long service life, is suitable for use on the railway passing platform, and has the functions of height adjustment and gauge adjustment, with strong practicability and is suitable for wide promotion and application. It should be understood that the opposite ends of the running rail 300 refer to the two ends in the width direction of the running rail 300.

[0031] As Figure 2 shown, in this embodiment, the elastic strip 120 includes a connecting portion 121 attached to the mounting base 110 and connected to the connecting piece 150 and a pressing portion 122 which is bent and arranged for elastically buckling the running rail 300.

Specifically, the elastic strip 120 is attached to the mounting base 110 through the connecting portion 121 to increase the contact area with the mounting base 110, thereby improving the stability of the overall structure after the connecting piece 150 connects the mounting base 110 and the elastic strip 120. Then, the running rail 300 is elastically buckled through the pressing portion 122 to fix the running rail 300. And because the connecting portion 121 and the pressing portion 122 are integrally formed, the strength of the elastic strip 120 is stable and reliable, it can bear a large lateral force and has a long service life.

[0032] As Figure 2As shown, in this embodiment, the mounting base 110 includes a support portion 111 that supports and connects the portion 121, and a limiting portion 112 that extends vertically upward and is inserted and cooperated with the gauge block 130. The limiting portion 112 and the support portion 111 are used to enclose a limiting groove 113 with the frame body 200, and the wall of the limiting groove 113 is used to abut and limit the height-adjusting pad 140. Specifically, the mounting base 110 supports and connects the portion 121 through the support portion 111, then is inserted and cooperated with the gauge block 130 through the limiting portion 112, and encloses the limiting groove 113 with the frame body 200 through the limiting portion 112 and the support portion 111, so as to abut and limit the height-adjusting pad 140 through the wall of the limiting groove 113, thereby cooperating with the elastic strip 120, the gauge block 130, and the height-adjusting pad 140 respectively to improve the stability of the overall structure.

[0033] As Figure 2 and Figure 4 shown, in this embodiment, the limiting portion 112 is concavely provided with a plugging groove 114 on the end face facing the running rail 300, and the gauge block 130 is convexly provided with a plugging protrusion 131 that is inserted and cooperated with the plugging groove 114. Specifically, the plugging groove 114 is inserted and cooperated with the plugging protrusion 131 to fix the gauge block 130, and then the gauge block 130 is horizontally abutted against the running rail 300, so as to adjust the gauge of the running rail 300.

[0034] In another embodiment, the limiting portion 112 is convexly provided with a plugging convex block on the end face facing the running rail 300, and the gauge block 130 is concavely provided with a wrapping groove that is inserted and cooperated with the plugging convex block. Specifically, the wrapping groove wraps the plugging convex block to achieve the insertion and cooperation and fixation on the limiting portion 112.

[0035] As Figure 3 shown, in this embodiment, the height-adjusting pad 140 is convexly provided with an ear plate 141 that extends into the limiting groove 113. Specifically, the ear plate 141 on the height-adjusting pad 140 extends into the limiting groove 113 to abut against the inner wall of the limiting groove 113, so as to cooperate with the ear plate 141 and the limiting groove 113 to achieve the limitation of the height-adjusting pad 140 after installation.

[0036] As Figure 3 shown, in this embodiment, there are two ear plates 141, and the two ear plates 141 are arranged oppositely on the height-adjusting pad 140 and are respectively used to extend into the limiting grooves 113 arranged at the opposite ends of the running rail 300. Specifically, the height-adjusting pad 140 extends into the limiting grooves 113 arranged at the opposite ends of the running rail 300 through the two ear plates 141 respectively to cooperate with the two limiting portions 112 respectively, so as to simultaneously limit the height-adjusting pad 140 through the two limiting grooves 113, realize the reliable fixation of the height-adjusting pad 140 after installation, and improve the stability of the overall structure of the fastener system.

[0037] AsFigure 4 As shown in the figure, in this embodiment, the gauge block 130 is provided with an avoidance notch 132 for avoiding the ear plate 141. Specifically, since the ear plate 141 needs to extend into the limit groove 113, the avoidance notch 132 is provided on the gauge block 130 to avoid the ear plate 141 through the avoidance notch 132 when installing the height-adjusting pad 140, so that the ear plate 141 can extend into the limit groove 113, thereby avoiding mutual interference and obstruction during component assembly.

[0038] As Figure 1 As shown in the figure, in this embodiment, the connecting member 150 includes a connecting bolt 151 passing through the connecting portion 121 and the supporting portion 111, and a locking nut 152 threadedly connected to the penetrating end of the connecting bolt 151. Specifically, the connecting bolt 151 passes through the connecting portion 121, the supporting portion 111 and the frame body 200, and then the locking nut 152 is threadedly connected to the penetrating end of the connecting bolt 151, so as to assemble the mounting base 110 and the elastic strip 120 on the frame body 200. Optionally, the connecting bolt 151 passes through the main beam of the frame body 200.

[0039] As Figure 5 As shown in the figure, the railway meeting platform of this embodiment includes the above-mentioned railway meeting platform running rail fastener system. Specifically, by adopting the above-mentioned railway meeting platform running rail fastener system on the railway meeting platform, the running rail 300 can be buckled and fixed, so as to ensure a long service life while facilitating the adjustment of the gauge and height of the running rail 300, with strong practicability and suitable for wide promotion and application. Optionally, the railway meeting platform includes a frame body 200 and a plurality of running rails 300 arranged at intervals on the frame body 200. It should be understood that the gauge of the running rail 300 may change during the hoisting of the frame body 200, and thus fine adjustment needs to be carried out through the gauge block 130. It should be understood that after the running rail 300 is installed, if there is a height difference between adjacent running rails 300, the height-adjusting pad 140 needs to be used for padding.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
