Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The clamp device suitable for steel rail sound wave detection as shown in fig. 1 to 3 comprises a clamp body, and is characterized in that: the clamp body comprises a lower cladding body 1 used for being combined with the steel rail 8, and cladding combination with the lower half section of the steel rail 8 can be achieved. Meanwhile, in order to realize more attachment and stable combination, one side of the lower cladding body 1 is extended with a cladding short edge 2, and the other side of the lower cladding body 1 is extended with a cladding long edge 3. In addition, the inner side of the coated long side 3 forms a sensor accommodating space, so that the laser linear sensor can be conveniently and properly clamped, accommodated and positioned. In order to avoid unnecessary displacements of the clamp body due to vibrations caused by the passage of trains, a main coupling mechanism may be provided on the covered short side 2. Correspondingly, a secondary coupling mechanism may be provided on the coated long side 3. Specifically, the main combining mechanism and the auxiliary collecting mechanism both comprise screw holes 4, and bolts 5 are arranged in the screw holes 4. Like this, even go into the locating hole of predetermineeing on the rail 8 through bolt 5, can realize the utility model discloses an effective locking combines.

In combination with the preferred embodiment of the present invention, the lower cladding body 1 is shaped to fit the rail 8 for the purpose of achieving a relatively tight fit. During the implementation, the outer shapes of the short covering sides 2 and the long covering sides 3 can be adapted to the outer structure of the rail 8. Like this, realize utility model whole laminating on rail 8 after follow-up locking, avoid appearing the resonance because improper combination clearance, do not influence laser sensor 7's data acquisition.

Further, in order to accommodate and limit the laser sensor 7, an accommodating groove is formed in the inner wall of the long covering edge 3, which is located in the sensor accommodating space. Therefore, after the installation, the laser sensor 7 can be embedded into the accommodating groove and clamped by proper external force, and front-back displacement and axial rotation cannot occur.

Combine the actual implementation to see, for the convenience of the utility model discloses the whole better laminating is in the 8 outsides of rail, wears to be equipped with the gasket (not shown in the figure) on the bolt 5. Therefore, the bolt 5 can apply force better during combination, and a combination gap possibly generated due to tolerance can be filled.

Further, considering that there may be differences in the shapes of different rails 8, in order to facilitate the selection of a clamp body with a proper shape for limiting and combining during construction, a label area 6 is disposed outside the coated long side 3. The tag area 6 may be accompanied by parameters adapted to the type of rail 8. From this, can be convenient for the user discerns the comparatively similar anchor clamps body of appearance fast, select suitable anchor clamps body to come the adaptation. Meanwhile, the outer edges of the lower cladding body 1, the cladding short edge 2 and the cladding long edge 3 are all provided with arc chamfers. In this way, the presence of sharp edges can be avoided, without scratching the user during installation, and without scratching the laser sensor 7.

Furthermore, in order to avoid the unstable combination caused by the improper unscrewing of the bolt 5 during the subsequent use, the top of the bolt 5 is provided with a hexagonal inner hole or a special-shaped inner hole. Therefore, the operation and maintenance personnel can adjust the screw by adopting a specific tool, and the screw is prevented from being operated and screwed by a common screwdriver during inspection.

The working principle of the utility model is as follows:

a worker checks parameters in the label area 6 outside the coating long edge 3 on the clamp body according to the type or the shape of the current steel rail 8, and selects and matches a proper clamp body.

The rail 8 is then pried slightly, the cladding short edge 2 is passed through the bottom of the rail 8, and the lower cladding 1 is guided to the bottom of the rail 8. Subsequently, the coated short side 2 and the coated long side 3 are kneaded, and the jig body is more preferably attached to the rail 8.

Subsequently, the cladding short edge 2 is positioned and combined with the steel rail 8 through the bolt 5. Then, the coated long side 3 is coupled to the rail 8 by the bolt 5. During this time, the laser sensor 7 can be placed in the sensor housing space. And then, the bolt 5 is screwed down, so that the coated long edge 3 is matched with the outer side of the steel rail 8, and the laser sensor 7 is stably clamped and limited.

After the installation is finished, the clamp body and the laser sensor 7 are stirred by appropriate force application, and the whole assembly can be completed without loosening.

During actual manufacturing, the clamp body is made of polytetrafluoroethylene, and the service life is prolonged. Meanwhile, the width of the cloth can be adjusted according to actual needs, and 1 cm to 2 cm can be selected.
