Preferably, a first rubber layer is disposed on the first contact surface 611, and a second rubber layer is disposed on the second contact surface 621. The steel rail can be better protected by the arrangement of the first rubber layer and the second rubber layer, the steel rail is prevented from being directly arranged on the first adjusting block 61 and the second adjusting block 62 to be in hard contact, the steel rail is prevented from being scratched or scratched, friction force between the first adjusting block 61 and the steel rail can be increased, friction force between the second adjusting block 62 and the steel rail is increased, and therefore the steel rail can be better fixed. Further, a first bearing can be arranged between the first adjusting block 61 and the first rotating shaft 631, a second bearing can be arranged between the second adjusting block 62 and the second rotating shaft 641, the arrangement of the first bearing enables the first adjusting block 61 to rotate more smoothly relative to the first rotating shaft 631, so that the first adjusting block 61 can better fit to the steel rail, and the arrangement of the second rotating shaft 641 enables the second adjusting block 62 to rotate more smoothly relative to the second rotating shaft 641, so that the second adjusting block 62 can better fit to the steel rail.

Third embodiment of guard rail lifting device

Referring to fig. 9 to 11, the present embodiment is different from the above embodiments in that:

in this embodiment, the guard rail lifting device further includes a limiting assembly 7, the limiting assembly 7 includes an adjusting bolt 71 and a limiting block 72, the adjusting bolt 71 is parallel to the length direction of the first fixing rod 81, a screw of the adjusting bolt 71 is in threaded connection with the second end of the first fixing rod 81, a part of the screw extends into the hollow portion 811, the limiting block 82 is in spherical hinge connection with an end of the screw of the adjusting bolt 71, the limiting block 72 is located in the hollow portion 811, the limiting block 72 has a third contact surface 721, and the third contact surface 721 is disposed toward the second fixing rod 82. The limiting assembly 7 can further fix the first fixing rod 81 and the second fixing rod 82 so as to ensure the reliability and stability of the rail clamping of the guard rail lifting device. For example, after the first fixing rod 81 and the second fixing rod 82 are fixed by the third bolt group 83, the adjusting bolt 71 is adjusted, so that the adjusting bolt 71 drives the limiting block 72 to move toward the second fixing rod 82 until the third contact surface 721 of the limiting block 72 is attached to and abutted against the second fixing rod 82, wherein the spherical hinge connection between the limiting block 72 and the adjusting bolt 71 enables the limiting block 72 to be better attached to the second fixing rod 82, so as to ensure the reliability of the limiting assembly 7 in fixing the first fixing rod 81 and the second fixing rod 82.

Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the utility model are possible to those skilled in the art, without departing from the spirit and scope of the utility model.
