DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] Example:

[0033] A high-speed railway bridge waterproof protective layer construction machine, such as Figure 1 As shown, it includes an upper frame 1, a base plate 2, an adjustment component 3 and a moving component 4. Among them, the upper frame 1 includes two cross beams 11 and two longitudinal beams 12, and the two cross beams 11 are welded and connected by two longitudinal beams 12. The upper frame 1 is connected to the base plate 2 through the adjustment component 3, and the adjustment component 3 can flexibly adjust the distance between the upper frame 1 and the base plate 2, so that the construction machinery and tools are adapted to the height of the roadbed 5 of the ballastless track, and the construction thickness of the concrete protective layer is controlled according to the construction requirements. The moving component 4 is located at both ends of the two cross beams 11 and the base plate 2. The moving component 4 can enable the construction machinery and tools to move forward and backward along the construction route, thereby improving the stability of the movement of the construction machinery and tools.

[0034] like Figure 1-2 As shown, the adjustment assembly 3 includes a screw rod 31 and an adjustment member 32. The bottom of the screw rod 31 is welded to the bottom plate 2, and a through hole 121 is opened in the middle of the two longitudinal beams 12. The end of the screw rod 31 away from the bottom plate 2 passes through the through hole 121 to achieve a detachable connection with the longitudinal beam 12. The adjustment member 32 is threadedly connected to the screw rod 31 and is located above the longitudinal beam 12. By rotating the adjustment member 32, the extension length of the screw rod 31 can be flexibly adjusted, thereby accurately controlling the distance between the upper frame 1 and the bottom plate 2. In this embodiment, the adjustment member 32 can be selected as a bolt.

[0035] like Figure 1-2 As shown, in this embodiment, the moving assembly 4 includes a first moving wheel 41 and a second moving wheel 42. Among them, there are four first moving wheels 41, all connected to the end of the crossbeam 11, and the first moving wheel 41 moves close to the top surface of the roadbed 5. There are four second moving wheels 42, and the four second moving wheels 42 are in a group of two, respectively welded to the two ends of the bottom plate 2, and the second moving wheels 42 move close to the side wall of the roadbed 5. The design of the moving wheel enables the entire construction machine to easily move along the roadbed 5 of the ballastless track, significantly improving the construction efficiency.

[0036] like Figure 1 , 2 As shown in Figure 4, in this embodiment, the side wall of the roadbed 5 is provided with a guide groove 6, which is arranged along the length direction of the roadbed 5, and the second moving wheel 42 is located in the guide groove 6. During construction, the second moving wheel 42 moves in the guide groove 6, and the guide groove 6 guides the walking path of the second moving wheel 42, which effectively improves the accuracy of construction and ensures the flatness of the surface of the concrete protective layer after construction.

[0037] like Figure 4 As shown, a gasket 61 is also provided at the lower end of the guide groove 6, and the main function of the gasket 61 is to adjust the slope of the guide groove 6. By adding, removing or replacing gaskets 61 of different thicknesses, construction personnel can fine-tune the construction slope of the machine according to actual needs to ensure that the concrete protective layer after construction has an ideal longitudinal drainage slope and improve the drainage effect of the concrete protective layer. In this embodiment, the guide groove 6 is selected as a channel steel.

[0038] like Figure 1-2 As shown, in order to increase the structural strength of the bottom plate 2, a reinforcement member 23 is welded on the upper end surface of the bottom plate 2, and the reinforcement member 23 is arranged along the length direction of the bottom plate 2. The reinforcement member 23 can ensure that the bottom plate 2 will not be deformed or damaged during the construction process, thereby extending the service life of the bottom plate 2. In this embodiment, the reinforcement member 23 is selected as a channel steel.

[0039] like Figure 1-2 As shown, in this embodiment, in order to improve the drainage effect of the concrete protective layer, a symmetrical transverse slope 21 is formed on the bottom plate 2 along the center to both sides, and the transverse slope 21 is high in the middle and low on both sides, so as to ensure that the concrete protective layer after construction has an ideal transverse drainage slope, guide rainwater and other surface water away from the track structure, reduce moisture penetration into the track foundation and internal structure, and reduce structural damage and corrosion problems caused by long-term water accumulation.

[0040] like Figure 1As shown, in this embodiment, in order to further enhance the construction quality of the protective layer, a vibrator 7 is further installed on the upper end surface of the base plate 2 for vibrating the concrete during the pouring process, thereby improving the density and flatness of the protective layer.

[0041] Working principle: During construction, a guide groove 6 is laid along the length direction of the side wall of the ballastless track 5, and a gasket 61 is placed at the lower end of the guide groove 6 according to the longitudinal slope requirements of the line to adjust the longitudinal slope of the guide groove 6, and the construction machine is placed in the ballast bed 5 so that the bottom plate 2 with a certain slope is attached to the concrete surface, and the second moving wheel 42 is placed in the guide groove 6. At this time, the vibrator 7 is turned on and the machine is moved at a uniform speed. The vibration wave generated by the vibrator 7 is indirectly transmitted to the concrete through the bottom plate 2, so that the concrete surface block quickly forms a longitudinal and transverse slope, and the vibration is completed at the same time, and the surface is manually finished before the initial setting of the concrete.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
