Description

Technical Field

[0001] The utility model belongs to the technical field of buckles, and in particular relates to a track monitoring point buckle. Background Art

[0002] Railway tracks, also known as rails, tracks, and tracks, are mainly used on railways and work with switches to allow trains to travel without turning. Railway tracks are usually composed of two parallel rails, which are fixed on sleepers and fastened by rail supports, fasteners, rail clamps, track clamps, spring bars, rail spikes and other railway accessories. Under the sleepers is ballast, which is also called sleepers, ash sleepers, or road sleepers. Its function is to distribute the weight of the rails and the pressure on the rails, maintain a fixed track gauge, and maintain the track gauge of the track.

[0003] In the past, the railway track monitoring point was fixed on the sleeper with steel plate adhesive material, but it is easy to fall off. The patent with application number CN201220083502.1 discloses an automatic remote monitoring device for the railway track itself, which mainly includes a connecting member and a measuring instrument connected to the rail; the connecting member mainly includes a screw, a fixing buckle and a prism; there are two fixing buckles, which are respectively buckled on the left and right sides of the rail foot of the rail; the screw is located at the bottom of the rail, and the two ends thereof pass through the fixing buckle respectively; a prism is set at one end of the screw; the measuring instrument is fixed on a fixed plane, and a signal transmitter is set corresponding to the measuring instrument. The utility model uses a prism and a measuring instrument to automatically and accurately monitor the settlement and displacement of the rail affected during the construction process in real time; in addition, the monitoring results can be remotely obtained through a remote computer, thereby achieving the purpose of ensuring railway safety. The above-mentioned automatic remote monitoring device for the railway track itself discloses a connecting fastener for installing a prism, but the connecting fastener needs to be used with two fixing buckles, and a single fixing buckle cannot be clamped with the rail when used.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0005] The utility model aims to provide a track monitoring point buckle, which adopts a single buckle solution to solve the problem that the previous railway track monitoring points are fixed on the sleepers by steel plate bonding materials and are easy to fall off.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Track monitoring point buckle, including:

[0008] The fastener has a card slot on the upper part and an avoidance slot on the lower part; the card slot has openings at the front end and both sides, and the bottom wall is horizontal and the top wall is inclined;

[0009] A connecting rod, the middle of which is located in the avoidance groove; the middle of the connecting rod is not provided with threads, one end of which is provided with a hook, and the other end is provided with an external thread and a nut matched with the thread;

[0010] A vertical screw rod is located at the top of the fastener; the upper half of the vertical screw rod is provided with external threads, while the lower half of the vertical screw rod is not provided with external threads.

[0011] Preferably, the height of the outer end of the top wall of the slot is greater than the height of the inner end thereof; and the inclination angle of the top wall of the slot is less than 10°.

[0012] Preferably, the opening direction of the avoidance groove is consistent with the front end opening direction of the card slot.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The track monitoring point clip of the utility model adopts a single fastener and a connecting rod to clamp on the track. The L-shaped monitoring prism is installed on the vertical screw at the top of the fastener. The height of the prism does not exceed the track and does not affect driving.

[0015] (2) The top wall of the fastener slot of the track monitoring point buckle of the utility model is inclined, which is convenient for locking with the shape of the track foot; a hook is provided at one end of the connecting rod, which can be locked with the other side of the track foot. When used in conjunction with the slot, the fastener can be fixed to the bottom of the track and is not easy to fall off. BRIEF DESCRIPTION OF THE DRAWINGS
