Description

Technical Field

[0001] The utility model belongs to the field of track construction, in particular to a flat vibration beam for a waterproof layer between ballastless track lines. Background Art

[0002] Ballastless track, also known as ballastless track, is a special railway track structure. Unlike traditional ballast track, ballastless track does not have a traditional ballast cushion layer, but uses other methods to provide support and stability.

[0003] The main feature of ballastless track is that the track is laid directly on the sand layer or special base material. It usually consists of the following parts: hard base layer, waterproof layer, isolation layer and upper track structure.

[0004] The main function of the vibration beam is to act on the waterproof layer to make it lay tightly without gaps. The overall structure of the vibration beam is rigid, with wheels of a certain height on both sides. When using it, you need to first lay walls of a certain height on both sides of the road, and then install limit rails on the walls for the wheels to travel. This limits the use scenario to a limit rail that matches the height of the wheels, which has great limitations. Utility Model Content

[0008] Furthermore, the fixing mechanism includes a plurality of connection holes that penetrate through the sleeve and the connecting rod and are evenly distributed along the height direction thereof, and the sleeve and the connecting rod are connected with a combination bolt through the connection holes.

[0009] Furthermore, the combined bolt is composed of a head, a stud and a nut. A washer can be sleeved on the outer peripheral side of the stud, and the washer is located between the nut and the sleeve.

[0010] Furthermore, the crossbeam includes a crossbar fixed on the frame and an insertion rod movably inserted at the outer end of the crossbar; in addition, a positioning mechanism is provided between the two for positioning the insertion rod after it is extended and retracted.

[0023] In the description of the present application, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] The ballastless track waterproof layer flat vibration beam provided in this specific embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a main body structure and an improved structure, wherein:

[0025] The main structure includes a frame 1, a vibrator 2 installed on the frame and two crossbeams 3, both ends of the two crossbeams 3 are connected to side frames 4, a mounting frame 5 is arranged below the side frames 4, a moving wheel 6 is arranged inside the mounting frame 5, and the mounting frame 5 is a U-shaped frame with an opening facing downward; specifically, an axle rod is installed on the moving wheel 6; at the same time, two mounting holes are symmetrically opened on the U-shaped frame, a bearing is installed in each mounting hole, and the inner wall of the U-shaped frame is fixed to the outer ring of the bearing, and the inner ring of the bearing is interference fit with the end of the axle rod, so that the moving wheel 6 can be rotatably connected;

[0026] The improved structure includes a support rod 7 connected between the mounting frame 5 and the side frame 4 and can be extended in the vertical direction, such as Figure 3 and Figure 4As shown, the support rod 7 is composed of a sleeve 701 fixed to the side frame 4 at the top and a connecting rod 702 movably inserted in the sleeve 701 and fixed to the mounting frame 5 at the bottom; in addition, a fixing mechanism 8 is provided between the two for fixing the connecting rod 702 at that position after it is extended and retracted, and the fixing mechanism 8 includes a plurality of connecting holes 801 uniformly distributed along the height direction of the sleeve 701 and the connecting rod 702, and the sleeve 701 and the connecting rod 702 are fixed by a combination bolt 802 through the connecting holes 801; in addition, The crossbeam 3 can also be extended and retracted in the horizontal direction, because the crossbeam 3 includes a crossbar 301 fixed on the frame 1 and an insertion rod 302 movably inserted at the outer end of the crossbar 301; in addition, a positioning mechanism 9 is provided between the two for positioning the insertion rod 302 after it is extended and retracted.
