Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figure 1As shown, this embodiment provides a push-pull type vibratory slurry leveling machine for high-speed railway concrete sealing layer, including a walking frame 1, a vibratory slurry leveling structure 2, and an adjustment structure 3. The walking frame 1 has four corners at its bottom, each equipped with a traveling wheel 4 that travels on the top of the track slab. The vibratory slurry leveling structure 2 includes a vibrating plate 2.1, a vibrating motor 2.2, and elastic telescopic wheels 2.3. The vibrating plate 2.1 is installed at the bottom of the walking frame 1, the vibrating motor 2.2 is installed at the top of the vibrating plate, and the elastic telescopic wheels 2.3 are located at each of the four corners at the top of the vibrating plate 2.1, and are used to travel along the side of the track slab. The adjustment structure 3 is located between the vibrating plate 2.1 and the walking frame 1, and is used to adjust the height and lateral movement of the vibrating plate 2.1.

[0018] In use, the traveling wheels 4 on both sides of the traveling frame 1 are supported on the top of the track slab, and the elastic telescopic wheels 2.3 are supported on the side walls of the track slab. Then, the vibration motor 2.2 is started, and the traveling frame 1 is manually pulled so that the entire leveling machine moves on the track slab. The vibrating plate 2.1 levels the concrete slurry. Specifically, in this embodiment, the width of the vibrating plate 2.1 is slightly smaller than the distance between the two track slabs. The elastic telescopic wheels 2.3 provide support to ensure that the vibrating plate 2.1 does not collide with the track slab. At the same time, the vibrating plate 2.1 can be pulled left and right to further compress one side of the elastic telescopic wheel 2.3, thereby controlling the lateral movement of the vibrating plate 2.1 and achieving leveling of the edge concrete.

[0019] Specifically, the traveling frame 1 includes two crossbeams 1.1 and two pairs of longitudinal beams 1.2. The two crossbeams 1.1 are parallel and spaced apart, and the ends of the two crossbeams 1.1 on the same side are connected by a pair of longitudinal beams 1.2. One traveling wheel 4 is installed at each end of the bottom of the longitudinal beam 1.2. The crossbeams 1.1 and longitudinal beams 1.2 can be fabricated using steel pipes available on the construction site, making the materials readily available and easy to manufacture.

[0020] In this embodiment, the adjustment structure 3 includes a lead screw 3.1, a connecting rod 3.2, and a positioning nut 3.3. Two lead screws 3.1 are provided, and the two lead screws 3.1 are fixedly installed on both sides of the top of the vibration plate 2.1. Two pairs of connecting rods 3.2 are provided, and each pair of connecting rods 3.2 is located on both sides of the lead screw 3.1, and the two ends of the connecting rods 3.2 are fixedly connected to the two crossbeams 1.1. Two positioning nuts 3.3 are threadedly installed on each lead screw 3.1, and the two positioning nuts 3.3 are located on the upper and lower sides of the connecting rod 3.2, respectively.

[0021] The connecting rod 3.2 further connects the two crossbeams 1.1, improving the overall stability and rigidity of the walking frame 1. At the same time, the connecting rod 3.2 is clamped by two positioning nuts 3.3, thereby using the positioning nuts 3.3 and the lead screw 3.1 to achieve the positioning of the height of the vibrating plate 2.1.

[0022] When adjusting the vibrating plate 2.1 upwards, first rotate the lower positioning nut 3.3 downwards, then rotate the upper positioning nut 3.3 downwards to adjust the vibrating plate 2.1 to a suitable height. Then rotate the lower positioning nut 3.3 upwards again, so that the two positioning nuts 3.3 clamp the connecting rod 3.2 from both the top and bottom. When adjusting the vibrating plate 2.1 downwards, directly rotate the upper positioning nut 3.3 upwards. After adjusting the vibrating plate 2.1 downwards to a suitable height, rotate the lower positioning nut 3.3 upwards again, so that the two positioning nuts 3.3 clamp the connecting rod 3.2 from both the top and bottom.

[0023] In this embodiment, the walking frame 1 also includes two pairs of diagonal braces 1.3 symmetrically distributed along the length of the vibrating plate 2.1. The bottom ends of each pair of diagonal braces 1.3 are rotatably connected to both sides of the top surface of the vibrating plate 2.1, and each pair of diagonal braces 1.3 is arranged in a cross configuration. A buckle 1.4 is rotatably installed on the crossbeam 1.1, and the buckle 1.4 fixes the top of the diagonal braces 1.3 to the crossbeam 1.1.

[0024] By setting the diagonal brace 1.3, the vibration plate 2.1 can be more stably installed on the walking frame 1. When adjusting the height of the vibration plate 2.1, first loosen the clip 1.4 so that the diagonal brace 1.3 can be disengaged from the clip 1.4. After the height of the vibration plate 2.1 is adjusted, put the diagonal brace 1.3 back into the clip 1.4 and then use the clip 1.4 to fix the diagonal brace 1.3.

[0025] The elastic telescopic wheel 2.3 includes a wheel body and an elastic telescopic rod disposed between the wheel body and the vibrating plate 2.1. The elastic telescopic rod provides force to support the wheel body against the side wall of the track plate. Specifically, the fixed end of the elastic telescopic rod is fixed to the top of the vibrating plate 2.1, and the wheel body is connected to the extended end of the elastic telescopic rod. When the wheel body moves along the side wall of the track plate, the elastic telescopic rod provides it with support.

[0026] Specifically, in this embodiment, the crossbeam 1.1 includes a first sleeve section 1.11, a screw section 1.12, a rod-shaped section 1.13, and a second sleeve section 1.14. The first sleeve section 1.11 is located in the middle position. The inner end of the screw section 1.12 is rotatably connected to the outer end of the first sleeve section 1.11. The inner end of the rod-shaped section 1.13 is fixedly connected to the outer end of the screw section 1.12. The second sleeve section 1.14 is rotatably sleeved on the outside of the rod-shaped section 1.13, and the end of the longitudinal beam 1.2 is fixedly connected to the second sleeve section 1.14. An inner support frame 5 is provided between the two screw sections 1.12 on the same side, and the inner support frame 5 is threadedly connected to the screw section 1.12. An inner support wheel 6 is provided at the bottom of the inner support frame 5, which is supported on the side wall of the track plate.

[0027] By rotating the outer end of the screw section 1.12, the screw section 1.12 is rotated. At this time, the threaded engagement between the screw section 1.12 and the inner support frame 5 allows adjustment of the inner and outer displacement of the inner support frame 5, enabling the inner support wheel 6 to be supported on the side wall of the track slab. Simultaneously, the distance between the support wheel and the side wall of the track slab can be controlled, limiting the lateral movement of the vibrating plate 2.1. This prevents the elastic telescopic wheel 2.3 from excessively displacing laterally and impacting the track slab under vibration or due to worker error, thus providing better protection for the vibrating plate 2.1 and improving the safety of the leveling operation.

[0028] Furthermore, a sliding rod 7 is slidably installed inside the first sleeve section 1.11. The end of the connecting rod 3.2 and the buckle 1.4 are both connected to the sliding rod 7. A first through hole 8 is provided in the middle of the first sleeve section 1.11 corresponding to the top of the crossbeam 1.1. Second through holes 9 are provided on both sides of the first sleeve section 1.11. The end of the connecting rod 3.2 and the buckle are both located within the range of the first through hole 8. Two longitudinal rods 10 located within the range of the first through hole 8 are fixedly installed on the top of one of the sliding rods 7.

[0029] The sliding rod 7, in conjunction with the connecting rod 3.2 and the diagonal brace 1.3, enables the sliding rod 7, the connecting rod 3.2, the diagonal brace 1.3, and the vibrating plate 2.1 to move laterally in the first pipe section 1.11. Furthermore, the inner support wheel 6 provides stable support on the side wall of the track plate, ensuring that the traveling wheel 4 does not move laterally on the top of the track plate during the lateral movement of the vibrating plate 2.1. This allows for more precise control over the lateral movement of the vibrating plate 2.1.

[0030] The second through hole 9 ensures that when the vibrating plate 2.1 moves laterally, the end of the connecting rod 3.2 and the latch 1.4 are not affected by the first sleeve section 1.11 when the sliding rod 7 moves within the first sleeve section 1.11. The longitudinal rod 10 allows workers to directly pull it laterally to move the sliding rod 7, thereby moving the vibrating plate 2.1 laterally, making operation easier.

[0031] More specifically, a connecting plate 11 is fixedly installed on the top of the first through hole 8 on the opposite side of the longitudinal rod 10. An operating rod 12 capable of rotating in the horizontal direction is provided on the top of the connecting plate 11. The end of the operating rod 12 away from the connecting plate 11 passes between the two longitudinal rods 10. The connecting plate 11 allows the operating rod 12 to be installed in the middle of the first sleeve section 1.11. When the worker moves the vibrating plate 2.1 laterally, he only needs to squeeze the operating rod 12 to one side, and use the operating rod 12 to squeeze the longitudinal rod 10 on that side to push the sliding frame to one side, thereby realizing the lateral movement of the vibrating plate 2.1.

[0032] By making the above settings, during the leveling of concrete slurry on straight sections, the support wheels on both sides are stably supported on the sidewalls of the track slab, ensuring that the entire traveling frame 1 does not shift laterally on the track slab, thus providing a stable foundation for the lateral movement control of the vibrating plate 2.1. During the leveling of concrete slurry on curved sections, a stable gap is maintained between the two support wheels and the sidewalls of the track slab, ensuring that the traveling wheels 4 do not detach from the top of the track slab when the entire traveling frame 1 passes through curved areas. Simultaneously, the lateral movement of the traveling frame 1 can be limited, preventing the vibrating plate from excessively shifting laterally and impacting the track slab.

[0033] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
