[0002] During railway track slab construction, the track slab must first be precisely fixed in the designed position. Then, self-compacting concrete is poured into the inner cavity of the slab through the grouting ports. Because the concrete injection generates buoyancy, which may cause the track slab to float and shift, affecting construction accuracy, a pressure device is often used to apply pre-pressure to the track slab for fixation before grouting. Commonly used pressure devices include... Figure 1 As shown, its design is suitable for situations where there is sufficient space on both sides of the track slab. The two ends of the pressing device are fixed to the ground by the diagonal tie rod 100 and connected to the template with bolts, thereby stabilizing the pressing track slab and providing stable construction conditions for concrete pouring.

[0003] However, in some tunnel track slab installation scenarios, the space left on both sides of the track slab is relatively small, and the existing pressing device is heavy and large in size, making the installation process time-consuming and difficult to adjust. Utility Model Content

[0037] Example 1

[0038] like Figures 2-7 As shown, a split-type pressing assembly for a track slab specifically consists of two pressing mechanisms positioned opposite each other on opposite sides of the track slab. Each pressing mechanism includes a reaction beam 1, a support 2, a reaction rod 3, and a support rod 4. One end of the reaction beam 1 is connected to the support 2 for contacting the track slab, and the other end is connected to the support rod 4 for contacting the ground. The support rod 4 vertically penetrates the reaction beam 1 and is threadedly connected to it. A rotating part 41 is provided at the top of the support rod 4. The reaction rod 3 is located between the support rod 4 and the support 2, vertically penetrating the reaction beam 1. An adjusting component 31 is provided on the reaction rod 3, threadedly connected to it and abutting against the top of the reaction beam 1. A connecting part 32 for connecting expansion bolts is provided at the bottom of the reaction rod 3.

[0039] Two pressing mechanisms press down on opposite sides of the track slab to achieve the pressing operation. One end of the reaction beam 1 is connected to the load-bearing support 2, and the other end is connected to the load-bearing rod 4. A reaction rod 3 is set between the load-bearing rod 4 and the load-bearing support 2, and then the reaction rod 3 is connected to the expansion bolt on the ground. In this way, under the action of the adjusting component 31, the reaction beam 1 can be pressed down. According to the lever principle, the load-bearing rod 4 abuts against the ground, thereby enabling the load-bearing support 2 to exert downward pressure on the track slab. The load-bearing rod 4 and the reaction rod 3 are set vertically, which can well adapt to the installation requirements in narrow spaces. The adjusting component 31 is threadedly connected to the reaction rod 3, and the load-bearing rod 4 is also threadedly connected to the reaction beam 1. The rotating parts 41 on the adjusting component 31 and the load-bearing rod 4 are both located above the reaction beam 1. This setting makes it easy for the operator to rotate the adjusting component 31 or the load-bearing rod 4 to flexibly adjust the position of the reaction beam 1, so that it can adapt to narrow working spaces.

[0040] In one or more embodiments, the connecting part 32 is an annular part, which is used to detachably connect with the expansion bolt. Specifically, before installing the pressing mechanism, the expansion bolt needs to be installed on the ground directly below the annular part. The expansion bolt is provided with a hook-shaped part, which fits through the annular part to quickly connect the annular part and the hook-shaped part. Through the movable connection between the hook-shaped part and the annular part, the reaction beam 1 can tilt to a certain extent during adjustment, thereby facilitating the installation and adjustment of the pressing mechanism by the operator.

[0041] In one or more embodiments, the adjusting member 31 includes an abutting nut, and the rotating part 41 includes a nut. By rotating the abutting nut, the position of the abutting nut on the upper reaction rod 3 is changed, thereby adjusting the position of the reaction beam 1. By rotating the nut, the load-bearing rod 4 is rotated, ensuring good contact between the load-bearing rod 4 and the ground, providing good downward pressure to the track slab. The abutting nut and the nut can be operated with common tools, making them easy to use.

[0042] In one or more embodiments, the bottom end of the load-bearing rod 4 is provided with a support seat 42, which is rotatably connected to the load-bearing rod 4; this makes it easy for the load-bearing rod 4 to rotate and for the support seat 42 to be adjusted to contact the ground.

[0043] In an optional embodiment, the support base 42 includes a sleeve 421 and a support plate 422. The sleeve 421 is vertically arranged, and the bottom of the sleeve 421 is connected to the support plate 422. The sleeve 421 is rotatably connected to the load-bearing rod 4. The support plate 422 increases the contact area with the ground, which facilitates the distribution of force and avoids the track plate from floating due to excessive local force on the ground. The end of the load-bearing rod 4 is inserted into the sleeve 421, and the sleeve 421 and the load-bearing rod 4 rotate relative to each other.

[0044] In one or more embodiments, the load-bearing support 2 includes a pressure plate 21 and two connecting plates 22. The connecting plates 22 are connected to the pressure plate 21, and the two connecting plates 22 are spaced apart. The connecting plates 22 are connected to the reaction beam 1. The pressure plate 21 is used to abut against the track plate. The pressure plate 21 abuts against the top of the track plate to increase the contact area and avoid excessive local stress that could damage the track plate.

[0045] In an optional embodiment, the reaction beam 1 is provided with a hinge rod 12, which passes through the reaction beam 1 and is rotatably connected to the reaction beam 1. Both ends of the hinge rod 12 are respectively connected to connecting plates 22. Through the rotatable connection between the hinge rod 12 and the reaction beam 1, the pressure plate 21 can rotate. The track slab at the curve of the railway has superelevation. When pressing down on the track slab at the curve of the railway track, the pressure plate 21 can be rotated to make the pressure plate 21 fit against the top surface of the track slab, which is convenient for pressing down on the track slab with superelevation. Specifically, the reaction beam 1 is located between two connecting plates 22, and the connecting plates 22 are perpendicular to the pressure plate 21.

[0046] In one or more embodiments, a plurality of vertically penetrating through holes 11 are arranged on the reaction beam 1. The through holes 11 are located between the load-bearing rod 4 and the load-bearing support 2, and the reaction rod 3 passes through the through holes 11. Depending on the actual use environment, the reaction rod 3 can be made to pass through the through holes 11 at different positions to adapt to the downward pressure of the track plate under different working conditions. The distance between the load-bearing rod 4 and the reaction rod 3 can be reduced by passing through different through holes 11, thereby adapting to use in narrower spaces. The plurality of through holes 11 are arranged at intervals along the length direction of the reaction beam 1.

[0047] In an optional embodiment, the through hole 11 is an oblong hole, which facilitates the passage of the reaction rod 3, allowing the reaction rod 3 and the reaction beam 1 to rotate relative to each other within a certain range, making it easy for operators to quickly adjust the position of the reaction beam 1.

[0048] Specifically, two connecting nuts are welded inside the reaction beam 1, and the load-bearing rod 4 is threadedly connected to the connecting nuts.

[0049] In this embodiment, a split-type downward pressing assembly for a track slab is used by connecting the connecting part 32 to the expansion bolt, rotating the adjusting part 31 and the load-bearing rod 4 to adjust the position of the reaction beam 1 so that the load-bearing support 2 abuts against the top of the track slab. Then, the adjusting part 31 and the load-bearing rod 4 are finely adjusted so that the load-bearing support 2 applies the required downward pressure to the track slab.

[0050] Example 2

[0051] like Figure 8 As shown, the track slab split-type pressing assembly of this embodiment has a structure that is roughly the same as that of Embodiment 1. The difference from Embodiment 1 is that the reaction beam 1 is provided with a level bubble 5. Through the level bubble 5, the operator can observe the levelness of the reaction beam 1, which makes it convenient for the operator to quickly adjust the reaction rod 3 and the load-bearing rod 4.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
