[0027] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figs. 1 to 4 This invention provides a more detailed description of a double-block ballastless track bed slab lifting device.

[0028] like Figs. 1 to 4 As shown in the figure, an embodiment of the present invention provides a double-block ballastless track slab lifting device, which includes a lifting device slide assembly 100. The lifting device slide assembly 100 is the main structure of the entire double-block ballastless track slab lifting device. The lifting device slide assembly 100 includes two transverse slides 110 and two longitudinal slides 120. The two transverse slides 110 are parallel to each other, and the two longitudinal slides 120 are parallel to each other. The transverse slides 110 and the longitudinal slides 120 are perpendicular to each other, forming a rectangle. This rectangular layout ensures that the lifting device has good stability and load-bearing capacity during operation, providing a solid foundation for the lifting of the track slab assembly. Several lifting lugs are provided on the transverse slides 110 and the longitudinal slides 120 for the hooks of gantry cranes to lift the lifting device slide assembly 100.

[0029] Two track bed plate hoisting assembly are arranged on the transverse sliding groove 110, and the two track bed plate hoisting assembly on one transverse sliding groove 110 are connected through a connecting rod 350, and the track bed plate hoisting assembly is used for suspending the track bed plate assembly 400. The sliding groove assembly 100 and the track bed plate hoisting assembly enable the suspended track bed plate assembly 400 to be stably suspended below the double-block ballastless track track bed plate hoist, so that hoisting and moving operations are facilitated.

[0030] In the utility model, one distance adjusting assembly is arranged at each end of the transverse sliding groove 110. The side, away from the connecting rod 350, of the track bed plate hoisting assembly abuts against the distance adjusting assembly; distance adjusting assemblies are arranged at the two ends of the longitudinal sliding groove 120, and the distance adjusting assemblies abut against the transverse sliding groove 110; adjusting handles 220 are arranged on the distance adjusting assemblies, and the distance of the track bed plate assembly 400 from the target position in the periphery is adjusted by rotating the adjusting handles 220. The axial direction of the longitudinal sliding groove 120 is the same as the axial direction of the track on the track bed plate assembly 400, and the axial direction of the transverse sliding groove 110 is perpendicular to the axial direction of the track on the track bed plate assembly 400. In the utility model, in the horizontal direction, the two sides parallel to the axial line of the track on the track bed plate assembly 400 are called left and right, and the two sides perpendicular to the axial line of the track on the track bed plate assembly 400 are called front and back.

[0031] Understandably, the track bed plate hoisting assembly comprises a hoisting upper part 310, the hoisting upper part 310 is provided with a square upper outer frame 311, the upper outer frame 311 is provided with upper rollers 312, and one side of the upper outer frame 311, opposite to the upper rollers 312, is connected with a hoisting screw rod 320. The hoisting screw rod 320 is threadedly connected with a hoisting lower part 330, and the hoisting lower part 330 is used for connecting the track bed plate assembly 400.

[0032] The hoisting screw rod 320 is threadedly connected with a lower nut 333, and the hoisting lower part 330 comprises a lower outer frame, the lower outer frame comprises an outer frame top 331 and two outer frame sides 332, and the outer frame top 331 is in contact connection with one side of the lower nut 333, close to the hoisting upper part 310. This design can ensure the stable installation of the hoisting lower part 330 on the hoisting screw rod 320. Since two through holes are arranged on the two tracks of the hoisted track bed plate assembly 400, the through holes are used for hoisting the tracks and related components, therefore two opposite track through holes are arranged on the outer frame sides 332, a track hoisting bolt 340 is arranged in the track through holes, the track hoisting bolt 340 passes through one track through hole and then passes through the through hole on the track, then the hoisting bolt 340 passes through the other track through hole, and finally the hoisting bolt 340 is tightened, so that the track and the hoisting lower part 330 are connected and used for hoisting.

[0033] It can be understood that the lifting screw 320 is threadedly connected with the upper outer frame 311. The lifting screw 320 below the outer frame top 331 is provided with a plurality of lower nuts 333, and adjacent two lower nuts 333 are in contact connection.

[0034] In the utility model, distance adjusting assembly includes adjusting fixed part 210, adjusting fixed part 210 on transverse sliding groove 110 is fixedly connected with transverse sliding groove 110, and adjusting fixed part 210 on longitudinal sliding groove 120 is fixedly connected with longitudinal sliding groove 120;Adjusting fixed part 210 is threadedly connected with adjusting handle 220, and adjusting handle 220 on transverse sliding groove 110 is in abutment with lifting upper part 310, and adjusting handle 220 of longitudinal sliding groove 120 is in abutment with transverse sliding groove 110.

[0035] When using, ensure that the upper roller 312 cooperates with the transverse sliding groove 110, ensure that the lifting assembly can smoothly move on the transverse sliding groove 110.Ensure that the sliding groove roller 111 cooperates with the longitudinal sliding groove 120, ensure that the transverse sliding groove 120 can move on the longitudinal sliding groove 110.First, the track bed plate assembly 400 on the isolation layer is lifted away from the isolation layer.Lifting bolt 340 is passed through the track on track bed plate assembly 400 so that track bed plate assembly 400 is connected to lifting lower part 330.Because the height of the horizontal plane of the two tracks on the same track bed plate assembly 400 is not consistent, such as at the turning place, the track bed plate assembly 400 is in an inclined state, so the height of the two tracks is also not consistent.In order to solve this problem, the lifting lower part 330 is designed.Adjust the lower nut 333, so that the lifting lower part 330 moves up and down on the lifting screw 320, to achieve the purpose that the lifting lower part 330 can adapt to tracks of different heights.When adjusting the lower nut 333 to the different heights of the two tracks of the same track bed plate assembly 400, the lifting tool sliding groove assembly 100 needs to be kept in a horizontal state.This setting can maintain the inclination angle of the track bed plate assembly 400 before lifting when maintaining the isolation layer needs to lift the track bed plate assembly 400 back, maximize the accuracy of the inclination angle, reduce the height adjustment in the vertical direction during lifting, and improve the lifting efficiency.

[0036] After the track bed plate assembly 400 is connected with the lifting lower part 330, the gantry crane is started, and the track bed plate assembly 400 is adjusted away from the isolation layer area needing to be maintained. After the track bed plate assembly 400 is maintained, the track bed plate assembly 400 is lifted back to the original position. During the whole lifting away and lifting back process, the lower nut 333 is preferably not rotated and adjusted after being arranged. In this way, the inclination angle of the track bed plate assembly 400 during the lifting back process is consistent with the inclination angle of the track bed plate assembly 400 before being lifted. Since the lower nut 333 is used to rotate on the lifting screw 320 to realize the adjustment of the inclination angle of the track bed plate assembly 400, the design can be infinitely adjusted, and the inclination angle of the track bed plate assembly 400 can be adjusted to a large extent. In order to avoid the rotation of the lower nut 333 during the lifting process, a plurality of lower nuts 333 are arranged on one lifting screw 320 in the utility model. This design can minimize the deviation of the inclination angle of the track bed plate assembly 400 caused by the rotation of the lower nut 333 during the lifting process.

[0037] During the lifting back process of the track bed plate assembly 400 to the isolation layer, the track bed plate assembly 400 is close to the isolation layer, and the track bed plate assembly 400 will usually deviate from the position to be placed in the horizontal direction. This deviation needs to be eliminated through the distance adjustment assembly.

[0038] When it is found that the track bed plate assembly 400 deviates to the left and right, the adjustment handle 220 on the transverse sliding groove 110 is rotated to move the track bed plate lifting assembly on the transverse sliding groove 110. If the track bed plate assembly 400 deviates to the front and back, the adjustment handle 220 on the longitudinal sliding groove 120 is rotated to move the track bed plate lifting assembly on the longitudinal sliding groove 120. When the adjustment handle 220 is rotated, since the adjustment handle 220 and the adjustment fixing part 210 are threadedly connected, the adjustment handle 220 will advance or retreat relative to the adjustment fixing part 210. When the track bed plate assembly 400 needs to be close to a certain direction, the adjustment handle 220 in the direction can be rotated to make the adjustment handle 220 in contact with the track bed plate lifting assembly or the transverse sliding groove 110. The distance by which the adjustment handle 220 needs to be rotated away from the track bed plate lifting assembly or the transverse sliding groove 110 is equal to the distance by which the track bed plate assembly 400 needs to be adjusted. The rotation adjustment handle 220 on the opposite side is adjusted again to push the track bed plate lifting assembly or the transverse sliding groove 110 to move to re-contact the rotation adjustment handle 220 that is out of contact, so as to adjust the deviation of the track bed plate assembly 400 relative to the target position. These adjustments are also infinite adjustments. The slight deviation can also be adjusted

[0039] In some embodiments, the adjusting fixed part 210 is provided with an adjusting motor 230, a motor shaft of the adjusting motor 230 is fixedly connected with an adjusting screw 240, the adjusting screw 240 is threadedly connected with the adjusting handle 220, and the adjusting motor 230 is used to drive the adjusting handle 220 to rotate. The adjusting motor 230 is electrically connected with a control assembly, and the control assembly is used to control rotation of each adjusting motor 230. Such a design can make it unnecessary for a construction worker to directly operate the double-block type ballastless track bed plate lifting device by manpower in deviation correction. Instead, the deviation is adjusted by operating the control assembly and then by the adjusting motor 230. The design can further reduce the requirement for the construction worker's physical strength and improve operation accuracy.

[0040] It can be understood that the side of the transverse sliding groove 110 facing the longitudinal sliding groove 120 is provided with a plurality of sliding groove rollers 111, which are in contact with the longitudinal sliding groove 120. The sliding groove rollers 111 can reduce the friction between the transverse sliding groove 110 and the longitudinal sliding groove 120, so that the lifting device moves more smoothly and improves work efficiency. It also improves the convenience and safety of the construction workers.

[0041] In addition, a plurality of positioning indicators are arranged on the transverse sliding groove 110 and the longitudinal sliding groove 120, and the positioning indicators are used to indicate the position in the vertical direction of the lifting device sliding groove assembly 100. In actual construction, a laser pen or the like can be used as the positioning indicator. At this time, the laser emitted by the laser pen can be irradiated on the isolation layer, thereby indicating the position to which the bed plate assembly 400 is installed in the current state, thereby providing more intuitive and accurate reference for the construction workers to adjust the deviation of the bed plate assembly 400 hoisting.

[0042] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
