[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0029] Combined with Figure 1 、 Figure 2 and Figure 3 As shown, the embodiment of the present invention provides a slab ballastless track fine adjustment machine, including a frame 1, an adjustment bracket 2 is arranged on the frame 1, the adjustment bracket 2 includes an adjustment beam 21 and a bracket beam 22, and a fine adjustment assembly is arranged on the bracket beam 22. Both ends of the adjustment beam 21 are respectively connected to the frame 1 through a lifting adjustment mechanism 7, and the lifting adjustment mechanism 7 is used to make both ends of the adjustment beam 21 move up and down relative to the frame 1 respectively; a horizontal adjustment mechanism 5 is connected between the adjustment beam 21 and the bracket beam 22, and the horizontal adjustment mechanism 5 is used to make the bracket beam 22 horizontally traverse relative to the adjustment beam 21.

[0030] The horizontal adjustment mechanism 5 and the lifting adjustment mechanism 7 respectively enable the bracket beam 22 to achieve horizontal transverse movement and longitudinal lifting, thereby adjusting the position of the fine adjustment assembly, enabling it to accurately connect and align with the elevation screw and the rotating shaft respectively, adjusting the track slab parameters, ensuring the accuracy of the adjustment parameters, ensuring the construction accuracy of the slab ballastless track, and at the same time being able to reduce the labor intensity of the staff and improve the construction efficiency.

[0031] The adjustment beam 21 is slidably and guidingly connected to the bracket beam 22. Specifically, a chute 23 through which the bracket beam 22 can slide may be connected to the adjustment beam 21. When the bracket beam 22 performs horizontal transverse movement, the bracket beam 22 slides through the chute 23, and the chute 23 plays a guiding role for the sliding of the bracket beam 22.

[0032] The adjustment beam 21 is provided with a hollowed-out area 24 through which the horizontal adjustment mechanism 5 and the fine adjustment machine assembly can pass. The horizontal adjustment mechanism 5 and the fine adjustment machine assembly respectively perform horizontal transverse movement within the corresponding hollowed-out area 24. The hollowed-out setting method can reduce the installation area, thereby reducing the volume of the entire fine adjustment machine. At the same time, it can reduce the weight and facilitate operation.

[0033] As Figure 1 shown, the horizontal adjustment mechanism 5 of the present application includes a telescopic device 51. One end of the telescopic device 51 is connected to the bracket beam 22, and the other end of the telescopic device 51 is connected to the adjustment beam 21. Since the horizontal position of the adjustment beam 21 relative to the frame 1 does not change, the telescopic function of the telescopic device 51 can be used to drive the bracket beam 22 to move horizontally, changing the horizontal parameters of the fine adjustment assembly.

[0034] In some embodiments, the telescopic device 51 may adopt an electric push rod structure, that is, the driving mechanism of the electric push rod is installed on the bracket beam 22, and the rod member 52 of the electric push rod is installed on the adjustment beam 21. Specifically, an installation seat may be provided on the adjustment beam 21, and a transverse connection ear seat 53 is provided on the installation seat. The free end of the rod member 52 is arranged on the transverse connection ear seat 53. Similarly, the driving mechanism can also be installed on the adjustment beam 21, and the rod member 52 can be arranged on the bracket beam 22, with a simple structure and convenient operation.

[0035] In some other embodiments, the telescopic device 51 may also adopt a telescopic rod structure, that is, a driving motor is provided on the bracket beam 22, the output shaft of the driving motor is connected to an outer sleeve, the inner sleeve is threadedly connected inside the outer sleeve, and the end of the inner sleeve is arranged on the adjustment beam 21. By rotating the motor, the outer sleeve is driven to rotate, thereby changing the relative position between the inner sleeve and the outer sleeve. Similarly, the driving motor can also be arranged on the adjustment beam 21, and the end of the inner sleeve can be arranged on the bracket beam 22.

[0036] In some other embodiments, the telescopic device 51 may also adopt the setting mode of a folding rod, that is, a driving motor is arranged on the bracket beam 22, the output shaft of the driving motor is in transmission connection with the driving rod, the end of the driving rod is hinged to the transmission rod, and the end of the transmission rod is installed on the adjusting beam 21. By driving the driving rod to rotate through the driving motor, the angle between the driving rod and the driven rod is changed, and the relative position between the bracket beam 22 and the adjusting beam 21 is changed. Similarly, the driving motor can also be arranged on the adjusting beam 21, and the end of the driven rod can be arranged on the bracket beam 22.

[0037] Combined with the above embodiments, it can be seen that the specific manner of the telescopic device 51 is not limited, as long as the relative movement between the bracket beam 22 and the adjusting beam 21 can be satisfied.

[0038] Such as Figure 2 As shown, in some preferred embodiments, the lifting and adjusting mechanism 7 of the present application includes connecting ear seats 72 arranged at both end portions on the two sides of the adjusting beam 21. The connecting ear seats 72 are hinged with sliding sleeves 73. The sliding sleeves 73 are slidably connected with vertical sliding rails 71 arranged on the frame 1. The middle of the sliding sleeves 73 is in transmission connection with a lead screw 74. One end of the lead screw 74 is connected with a driving device 75 arranged on the frame 1, and the other end of the lead screw 74 is connected with the frame 1.

[0039] During use, the fine-tuning machine control system issues a lifting command, the driving device 75 drives the lead screw 74 to rotate. When the lead screw 74 rotates, it drives the sliding sleeve 73 to slide vertically in the vertical sliding rail 71. During the vertical sliding of the sliding sleeve 73 on the vertical sliding rail 71, it drives the connecting ear seat 72 to slide vertically, so as to realize the lifting of the adjusting beam 21 and the bracket beam 22. The lifting and adjusting mechanism 7 enables the adjusting bracket 2 to drive the fine-tuning assembly to lift, thereby realizing accurate connection and alignment.

[0040] Among them, the vertical sliding rail 71 plays a role in guiding during the sliding process, increasing the accuracy of positioning. At the same time, it can effectively increase the smoothness of the sliding process.

[0041] In some other preferred embodiments, the lifting and adjusting mechanism 7 of the present application may also adopt the setting mode of a worm and worm gear lift. In this setting mode, the driving mechanism of the worm and worm gear lift is arranged inside the sliding sleeve 73. The worm is vertically arranged inside the sliding sleeve 73 and is in transmission connection with the worm gear on the driving mechanism. During use, the driving mechanism rotates, and drives the sliding sleeve 73 to move up and down through the action relationship between the worm and the worm gear, thereby adjusting the position of the bracket beam 22 in the vertical direction.

[0042] In some other preferred embodiments, the lifting and adjusting mechanism 7 of the present application may also adopt the setting mode of folding rods. In this setting mode, the driving motor is arranged on the frame 1, the output shaft of the driving motor is in transmission connection with the driving rod, the end of the driving rod is hinged to the driven rod, and the end of the driven rod is arranged on the sliding sleeve 73. By driving the driving rod to rotate by the driving motor, the angle between the driving rod and the driven rod is changed, and then the adjusting beam 21 is driven to move in the vertical direction through the sliding sleeve 73.

[0043] Combined with the above embodiments, it can be seen that the specific manner of the lifting and adjusting mechanism 7 is not limited, as long as the relative movement between the bracket beam 22 and the adjusting beam 21 can be satisfied.

[0044] In order to change the rotation speed of the output shaft of the driving motor, the driving motors described in the present application can all be connected to a speed reducer or a transmission.

[0045] The frame 1 of the present application is a gantry frame, which saves material costs, and a cable trough parallel to the adjusting beam 21 is provided on the top side cross beam of the gantry frame. Further optimized, an electric control box 4 is also arranged on the frame 1, and a fine adjustment machine control system and an energy storage device are installed inside the electric control box 4. The energy storage device provides a power source for the fine adjustment of the slab track without ballast. Moving wheels 3 for moving the frame 1 are also arranged at the bottom of the frame 1. The overall structure of the present application has a relatively light self-weight and can be manually pushed.

[0046] The single fine adjustment machine assembly of the present application includes an elevation adjustment mechanism 6 and a track alignment adjustment mechanism 8 respectively connected to the bracket beam; the elevation adjustment mechanism 6 is used to cooperate with the elevation adjustment screw rod, and the track alignment adjustment mechanism 8 is used to cooperate with the track alignment adjustment screw rod to realize the automatic adjustment of the position parameters of the track slab.

[0047] There are two elevation adjustment mechanisms 6 in the present application. The two elevation adjustment mechanisms 6 are respectively close to the two ends of the bracket beam 22 and are respectively connected to the elevation screw rods, and the track alignment adjustment mechanism 8 is located between the two elevation adjustment mechanisms 6, meeting the construction requirements.

[0048] In some embodiments, the elevation adjustment mechanism 6 and the track alignment adjustment mechanism 8 of the present application are both composed of a driving mechanism and a vertical shaft vertically arranged on the driving mechanism. A connection structure is provided at the bottom of the vertical shaft. When in use, it is connected to the screw for adjusting the track elevation or track alignment parameters through their respective connection mechanisms. The driving mechanism operates, drives the screw to rotate through the vertical shaft, and then adjusts the parameters of the track slab. This technology is already relatively mature in the prior art. Among them, the driving mechanism can be composed of a motor or a form of motor + reduction box. The vertical shaft can be a simple shaft structure, with its top directly connected to the output shaft of the driving mechanism (here, the output shaft is the output shaft of the motor or the output shaft of the reduction box). The vertical shaft can also be a universal shaft structure, that is, the vertical shaft is universally connected to the driving mechanism, and the vertical shaft is also universally connected to the connecting piece arranged on the vertical shaft. Thus, it can be ensured that even if the vertical shaft does not move in place and there is a certain angular deviation between the vertical shaft and the screw, the angle between the universal shaft and the screw can be adjusted through the universal connection structure to make it vertically connected to the screw.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
