DETAILED DESCRIPTION

[0027] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with specific embodiments.

[0028] As shown in Figure 3 The utility model provides a prevent loose type rail side equipment installation base, including clamping block 1 and installation block 2, installation block 2 is provided with the equipment mounting panel 7 for installing rail side equipment, clamping groove is opened in the clamping block 1 and installation block 2, the opening of clamping groove on the clamping block 1 and installation block 2 is opposite, is used for clamping the both sides of rail bottom, still including the connecting rod 3 of through clamping block 1 and installation block 2, the both ends of connecting rod 3 are used for clamping block 1 and installation block 2 with nut 4 cooperation and are pulled tight and are stably clamped on rail bottom, still including the loosening prevention component I 9 for preventing nut 4 rotation.

[0029] The utility model prevents the effect of loosening component I 9 in that nut 4 cannot retreat after stopping rotation, so that clamping block 1 and installation block 2 that are pulled tight by connecting rod 3 can keep the interval. Clamping groove is opened on clamping block 1 and installation block 2, so that clamping block 1 and installation block 2 can be clamped on the both sides of rail bottom to avoid slipping. In some embodiments, the clamping groove is wedge-shaped, which can better play a guiding role, so that clamping block 1 and installation block 2 can stably clamp the rail bottom under the tensioning action of the connecting rod.

[0030] Clamping groove is provided with insulating pad 6, which is made of insulating material and can isolate the voltage carried by the steel rail to protect the detection equipment on the rail clamp.

[0031] Specifically, as shown in Figure 1 , Figure 2 In this embodiment, the loosening component I 9 is sheet-shaped, the first end 91 is bent to abut against the side wall of the nut 4, and the second end 92 is bent to abut against the side wall of the clamping block 1 or the installation block 2, so that the loosening component I 9 cannot rotate by itself and cannot rotate relative to the nut 4.

[0032] The nut 4 at the side of the clamping block 1 and the installation block 2 is provided with the loosening component I 9. The second end 92 of the loosening component I 9 is bent to abut against the side wall of the clamping block 1 or the installation block 2, which is equivalent to limiting the rotation direction of the loosening component I 9, so that it cannot rotate. After the first end 91 of the loosening component I 9 abuts against the side wall of the nut 4, it is also equivalent to limiting the rotation direction of the nut 4, so as to prevent loosening caused by rotation of the nut 4.

[0033] It can be understood that, in order to better limit the rotation direction of the nut 4, the nut 4 is a square column, for example, a regular hexagonal column; the first end 91 of the loosening component I 9 is divided into at least two parts, and each part abuts against a different side of the nut 4. As shown in Figure 2As shown, the first end 91 of the anti-loosening component I9 is divided into two parts, which abut against two adjacent side surfaces of the nut 4 respectively, thereby clamping the nut 4 so that the nut 4 cannot rotate.

[0034] In addition, in order to prevent the anti-loosening component I9 from falling off, the connecting rod 3 can also penetrate the anti-loosening component I9 and press the anti-loosening component I9 tightly by the nut 4. After such arrangement, a firm interlocking relationship is formed between the anti-loosening component I9 and the nut 4, which can withstand the vibration generated during train operation.

[0035] In some embodiments, in order to further prevent loosening, a pin hole is opened on the connecting rod 3 behind the nut 4, and a retreat prevention pin 5 is inserted into the pin hole to prevent the nut 4 from retreating. Since the rotation of the nut 4 will inevitably form movement in the axial direction of the connecting rod 3, the retreat prevention pin 5 arranged on the connecting rod 3 limits the axial position of the nut 4, which can avoid loosening of the nut 4 from another dimension.

[0036] In the present embodiment, since all the devices are installed on the device mounting plate 7, it is also necessary to avoid loosening of the device mounting plate 7. Specifically, the device mounting plate 7 is fastened to the mounting block 2 by means of mounting bolts 8; the mounting bolts 8 are even in number, and between every two mounting bolts 8, an anti-loosening component II 10 is arranged to prevent the mounting bolts 8 from rotating.

[0037] The purpose of arranging the anti-loosening component II 10 is to make the two mounting bolts 8 form an interlocking relationship to avoid loosening caused by rotation. Specifically, the anti-loosening component II 10 is in the shape of a sheet, the first end 101 of which is bent to abut against the side wall of the head of a certain mounting bolt 8, and the second end 102 is bent to abut against the side wall of the head of another mounting bolt 8, so that the anti-loosening component II 10 itself cannot rotate and the anti-loosening component II 10 and the mounting bolts 8 cannot relatively rotate.

[0038] The principle of preventing the bolts from rotating by the anti-loosening component II 10 is consistent with that of the anti-loosening component I9, which will not be described here. The difference is that the two ends of the anti-loosening component II 10 abut against the side walls of the two bolts respectively, so that the anti-loosening component II 10 itself does not rotate by two-point fixation. In addition, the anti-loosening component II 10 limits the rotation direction of the bolt head, so that both the bolts cannot rotate.

[0039] Similarly, the mounting bolts penetrate the anti-loosening component II and press it tightly to avoid the anti-loosening component II from falling off.

[0040] More specifically, the head of the mounting bolt 8 is a square column, for example, a hexagonal column; the first end 101 and the second end 102 of the anti-loosening component II 10 each comprises at least two parts, and each part is in close contact with a different side wall of the head of the mounting bolt 8. As with the first end 91 of the anti-loosening component I, the first end 101 and the second end 102 of the anti-loosening component II 10 are each divided into two parts, which are in close contact with two adjacent side walls of the head of the mounting bolt 8, thereby clamping the mounting bolt 8 and preventing the mounting bolt 8 from rotating.

[0041] The anti-loosening component I 9 and the anti-loosening component II 10 in the embodiment are easy to install and implement; have simple structure, low cost, and are easy to mass-produce; are not easy to loosen, stable in installation, and long in service life in effect. Meanwhile, the anti-loosening component I and the anti-loosening component II are convenient to remove and can be reused, thereby saving use cost.

[0042] The above is only the preferred embodiment of the present application, and it should be noted that the above preferred embodiment should not be regarded as limiting the present application, and the protection scope of the present application should be limited by the scope defined in the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
