Description

Technical Field

[0001] The invention relates to the technical field of track construction equipment, and in particular to intelligent fine-tuning-pouring integrated construction equipment for high-speed railway slab ballastless tracks. Background Art

[0002] During the entire structural construction process of the CRTS III slab track, the fine-tuning of the track slab and the pouring of self-compacting concrete are the key and difficult points of construction. When laying the ballastless track, it is necessary to use a fine-tuning device to adjust the track slab in the vertical, horizontal and longitudinal directions to ensure that the three-dimensional spatial position of the track slab meets the design requirements to ensure the good smoothness of the track structure. After the fine-tuning is completed, it is necessary to pour self-compacting concrete. During the pouring process, the flow of self-compacting concrete will generate buoyancy on the track slab, which will cause changes in the three-dimensional spatial position of the track slab, affecting the smoothness of the track structure and further affecting the safe operation of the train. Therefore, how to efficiently and accurately achieve the fine-tuning of the track slab and ensure the stability of the spatial position of the track slab during the pouring of self-compacting concrete are technical problems that need to be solved in the construction process of CRTS III slab track.

[0003] During the construction of CRTSⅢ slab ballastless track, the base plate, isolation layer and rubber cushion layer are constructed, the self-compacting concrete steel mesh is laid and the track plate is roughly laid. When the track plate is initially positioned, the track plate is fine-tuned, and after the fine-tuning construction, the formwork and clamping device are installed, and finally the self-compacting concrete is poured. Therefore, fine-tuning and pouring construction are the key links in ballastless track construction.

[0004] During the fine-tuning construction process, usually one or two workers operate the total station and prism, and one worker operates the fine-tuning software to direct four workers to adjust four traditional fine-tuning claws at the same time, and jointly adjust the spatial position of the track plate to complete the fine-tuning construction. During the pouring construction process, first install the self-compacting concrete formwork and traditional clamping device on the fine-tuned track plate. The self-compacting concrete is mainly mixed centrally at the mixing station, transported to the construction site by the concrete transport vehicle, and then transported to the top of the track plate to be poured by the truck crane or gantry crane. The high fluidity of the self-compacting concrete is used to fill the gap between the track plate and the base plate to complete the pouring construction.

[0005] At present, the commonly used method is "total station + traditional fine-tuning claw + traditional pole-type clamping device" to achieve the fine-tuning of the track plate and the pouring of self-compacting concrete. There are the following shortcomings:

[0006] The existing fine-tuning construction and pouring construction are independent of each other and have a long interval, so the construction continuity is not strong. During the interval, the environmental load will seriously affect the fine-tuning effect of the track slab.

[0007] In addition, during the fine-tuning construction process, it is necessary to carry the traditional fine-tuning claw to the construction site. Manual installation of the traditional fine-tuning claw is rather cumbersome and time-consuming. The specific fine-tuning process requires the cooperation of multiple people. The fine-tuning claw operator needs to constantly communicate with the fine-tuning software operator, which consumes a lot of manpower. In addition, the efficiency of multi-person collaborative construction is low, and the accuracy of manual adjustment is difficult to guarantee.

[0008] Secondly, self-compacting concrete is mixed in a centralized manner at a mixing station and transported to the construction site by transport vehicles for on-site construction. Since the working performance of self-compacting concrete is greatly affected by the stagnation time, the quality of self-compacting concrete is uneven during on-site pouring construction, which seriously affects the quality of the pouring construction.

[0009] The buoyancy generated by the self-compacting concrete pouring operation on the track plate is mainly controlled by the clamping device. At present, the number of clamping devices required for each track plate during on-site construction operations is large and the size is large, which makes the on-site transportation, installation and disassembly procedures cumbersome and consumes a lot of manpower and material resources during the construction process. At the same time, the connection between the traditional clamping device and the base plate is prone to stress concentration, resulting in initial damage such as cracking of the base plate during the pouring process.

[0047] Example

[0048] like Figures 1 to 7 As shown, in this embodiment, a high-speed railway slab ballastless track intelligent fine-tuning-pouring integrated construction equipment is provided, including: a self-compacting concrete mixing tank 1 is provided on a movable body 19, and the rear side of the self-compacting concrete mixing tank 1 is a raw material supply carriage 2, and the raw material supply carriage 2 contains raw materials such as cement, aggregate, and powder. The raw material supply carriage 2 is connected to the self-compacting concrete mixing tank 1 through a feeding pipe 3, and a power mechanism is provided in the raw material supply carriage 2. When the storage in the self-compacting concrete mixing tank 1 is insufficient, the power mechanism injects the self-compacting concrete raw materials into the mixing tank through the feeding pipe 3 for mixing; the bottom of the self-compacting concrete mixing tank 1 is a mixing tank support seat 4, and the center of the mixing tank support seat 4 is provided with a pouring port (not shown in the figure). Two positioning bearing columns 17 are connected to both ends of the mixing tank support seat 4, and the bottom ends of the two positioning bearing columns 17 located at the same end are commonly connected to a bearing crossbeam 18, and both ends of the bearing crossbeam 18 are provided with track plate positioning adjustment mechanisms, and the bottom of the bearing crossbeam 18 is connected to a telescopic mechanism, and the telescopic mechanism is connected to an anti-floating pressure bar 10. In this embodiment, the telescopic mechanism can be a hydraulic telescopic rod 11.

[0049] In this embodiment, the track plate positioning and adjustment mechanism includes a positioning image acquisition device, a vertical sliding mechanism connected to the end of the bearing crossbeam 18, a lateral sliding mechanism connected to the vertical sliding mechanism, and a longitudinal sliding mechanism connected to the lateral sliding mechanism, and a track plate fixing bolt 6 is provided on the side of the longitudinal sliding mechanism close to the track plate. The vertical sliding mechanism drives the lateral sliding mechanism to achieve lifting and lowering movement in a direction perpendicular to the ground; the lateral sliding mechanism drives the longitudinal sliding mechanism to achieve translation in a direction perpendicular to the track; and the longitudinal sliding mechanism drives the track plate fixing bolt to achieve translation in a direction parallel to the track. The positioning image acquisition device is connected to the main controller, and the main controller is connected to the vertical sliding mechanism, the lateral sliding mechanism and the longitudinal sliding mechanism. The movement of the vertical sliding mechanism, the lateral sliding mechanism and the longitudinal sliding mechanism is controlled by the control software preset in the controller to achieve the docking of the track plate fixing bolt and the track plate hoisting hole.

[0050] In this embodiment, the positioning image acquisition device is installed on the side of the vertical sliding mechanism close to the track plate. The positioning image acquisition device is a positioning camera 5, and the positioning camera 5 is connected to a display for displaying the collected real-time video. The positioning camera 5 collects video data in real time and displays it to the operator through the display. The operator adjusts the position of the movable body in real time according to the transmitted video information until the track plate hoisting hole is located within the automatic installation requirement range of the intelligent fine-tuning claw (i.e., the track plate positioning adjustment mechanism).

[0051] Specifically, in this embodiment, the vertical sliding mechanism includes an L-shaped connecting rod 20, a lifting device 21 and a vertical adjustment block 9; one end of the L-shaped connecting rod 20 is connected to the load-bearing beam 18, and the other end of the L-shaped connecting rod 20 is connected to the lifting device 21; the telescopic end of the lifting device 21 is connected to the vertical adjustment block 9. Specifically, in this embodiment, the lifting device 21 can be a hydraulic telescopic cylinder or an electric telescopic cylinder. When the lifting device 21 is a hydraulic telescopic cylinder, the control system (main controller) can issue instructions to control the hydraulic oil to flow into (out of) the hydraulic telescopic cylinder, thereby controlling the extension or retraction of the vertical adjustment slider 9, thereby achieving lifting in the vertical direction. When the lifting device 21 is an electric telescopic cylinder, the control system (main controller) can issue instructions to control the start of the electric telescopic cylinder, thereby controlling the extension or retraction of the vertical adjustment slider 9, thereby achieving lifting in the vertical direction.

[0052] Combination Figure 3 , Fig. 9As shown, in this embodiment, the lateral sliding mechanism includes a lateral adjustment block 7 slidably connected to the vertical adjustment block 9, and a lateral driving device 24 disposed inside the vertical adjustment block 9 to drive the lateral adjustment block 7 to move. Specifically, in order to achieve the slidability between the lateral adjustment block 7 and the vertical adjustment block 9, a lateral slide rail 28 is disposed on the bottom of the vertical adjustment block 9, and a lateral slide groove 22 matching the lateral slide rail 28 is disposed on the top of the lateral adjustment block 7; lateral racks 26 are disposed on both sides of the lateral slide groove 22, and the lateral driving device 24 is disposed in the internal space of the vertical adjustment block 9, and is driven to connect two lateral gears 27 matching the lateral racks 26, and rectangular through holes (not shown in the figure) are also disposed on both sides of the bottom of the vertical adjustment block 9, and the rectangular through holes are used to achieve the matching meshing contact between the lateral racks 26 and the lateral gears 27. When the vertical adjustment block 9 is lifted and retracted with the lifting device 21, the transverse adjustment block 7 is lifted and retracted by the engagement between the transverse slide rail 28 and the transverse slide groove 22, and the transverse drive device 24 drives the two transverse gears 27 to rotate, thereby driving the transverse adjustment block 7 to move under the matching meshing action with the transverse rack 26. The transverse drive device 24 can be a servo motor. When the system issues a control command, the servo motor drives the transverse gear 27 to rotate forward or reverse, and the transverse gear and the transverse rack mesh with each other, thereby driving the transverse adjustment block 7 to achieve reciprocating transverse movement in the direction perpendicular to the track.

[0053] Combination Figure 3 , Fig. 9As shown, the longitudinal sliding mechanism includes a longitudinal adjustment block 8 slidably connected to the transverse adjustment block 7, and a longitudinal driving device 25 arranged inside the transverse adjustment block 7 to drive the longitudinal adjustment block 8 to move. Specifically, in order to achieve the sliding between the longitudinal adjustment block 8 and the transverse adjustment block 7, a longitudinal slide rail 29 is arranged on the bottom of the transverse adjustment block 7, and a longitudinal slide groove 23 matching the longitudinal slide rail 29 is arranged on the top of the longitudinal adjustment block 8; similarly, similar to the setting structure of the transverse adjustment block 7, longitudinal racks (not shown in the figure) are also arranged on both sides of the longitudinal slide groove 23, the longitudinal driving device 25 is arranged in the internal space of the transverse adjustment block 7, and is driven and connected to two longitudinal gears matching the longitudinal racks, and rectangular through holes (not shown in the figure) are also arranged on both sides of the bottom of the transverse adjustment block 7 to achieve matching meshing contact between the longitudinal racks and the longitudinal gears. When the lateral adjustment block 7 is raised and lowered along with the vertical adjustment block, the longitudinal adjustment block 8 is driven to rise and fall through the engagement between the longitudinal slide rail 29 and the longitudinal slide groove 23, and the longitudinal drive device 25 drives the two longitudinal gears to rotate, thereby driving the longitudinal adjustment block 8 to move under the matching meshing action with the longitudinal rack. The longitudinal drive device 25 can also be a servo motor. When the system issues a control command, the servo motor drives the longitudinal gear to rotate forward or reverse, and the longitudinal gear and the longitudinal rack mesh with each other, thereby driving the longitudinal adjustment block 8 to achieve reciprocating longitudinal movement in the direction parallel to the track.

[0054] In this embodiment, the steps of using the high-speed railway slab ballastless track intelligent fine adjustment-pouring construction integrated equipment for construction are as follows: Figure 8 As shown. When mixing self-compacting concrete on site, the power mechanism injects the self-compacting concrete raw materials into the self-compacting concrete mixing tank 1 through the feed pipe 3 before fine-tuning, and the automatic mixing module performs mixing. The intelligent fine-tuning claw of the integrated equipment for intelligent fine-tuning and pouring construction of high-speed railway slab ballastless track is shown in Figure 1. Figure 3 , 4 As shown, the positioning camera 5 can capture the position of the track plate hoisting hole in real time and transmit it to the operator. The operator adjusts the vehicle position in real time according to the transmitted information until the track plate hoisting hole is within the automatic installation requirement range of the intelligent fine-tuning claw; the track plate fixing bolt 6 is used to dock with the track plate hoisting hole and perform fine-tuning; the horizontal, vertical, and vertical sliding mechanisms can adjust the position of the track plate fixing bolt 6 according to the position information. When the vehicle completes the initial position adjustment, the fine-tuning software equipped in the vehicle system issues instructions to control the horizontal, vertical, and vertical sliding mechanisms to complete the docking of the track plate fixing bolt 6 with the track plate hoisting hole. After docking, the fine-tuning software issues an adjustment instruction according to the current spatial position information of the track plate, and the intelligent fine-tuning claw fine-tunes the track plate according to the adjustment instruction until its spatial position meets the design requirements (at this stage, the hydraulic telescopic rod 11 has not yet been extended, and the anti-floating pressure bar 10 is not in contact with the top of the track plate). After fine-tuning, the track plate pressure plate 12 and the base plate fixing plate 13 are installed.

[0055] After the intelligent fine-tuning claw completes the fine-tuning of the track plate, the hydraulic telescopic rod 11 extends to the top surface of the track plate. After that, the self-compacting concrete mixing tank is opened, and the self-compacting concrete flows down through the central pouring port of the mixing tank support seat and is poured. During the pouring process, the buoyancy generated by the self-compacting concrete is transmitted to the vehicle body by the anti-buoyancy pressure bar and offset by the weight of the vehicle body.

[0056] Combination Figure 6 , Figure 7 As shown, after the pouring is completed, the mouth of the self-compacting concrete mixing tank is closed, and the installation of the telescopic rod 15 begins. A hanging seat 32 is provided on the outer side of the track plate pressure plate 12. The top of the telescopic rod 15 is hung on the hanging seat 32 through a hanging ring 30. A telescopic barrel 16 is rotatably provided on the bottom end of the telescopic rod. An internal thread is provided inside the telescopic barrel 16. A fixing ring 33 is provided on the upper surface of the base plate fixing plate 13. The fixing ring 33 is connected to a hanging buckle 31. An external thread matching the internal thread is provided on the outer side of the hanging rod 34 of the hanging buckle 31. By tightening the telescopic barrel 16, the track plate pressure plate 12 and the base plate fixing plate 13 are tightened under the action of the internal thread and the external thread to limit the floating of the track plate caused by the residual buoyancy after the anti-floating pressure bar is removed. The installation effect of the telescopic rod is as shown in the figure. Figure 6 As shown, the details are as follows Figure 7 After the anti-floating rod is installed, the hydraulic telescopic rod controls the anti-floating pressure bar to retract, the fine-tuning software issues an adjustment command to withdraw the intelligent fine-tuning claw, and the operator controls the equipment to move to the next track plate.

[0057] In summary, the high-speed railway slab track intelligent fine-tuning-pouring integrated construction equipment described in the embodiment of the present invention has (1) a high degree of intelligence: it can realize the automatic installation of the track plate fine-tuning device and the anti-floating device, without consuming manpower for the transportation and installation of traditional fine-tuning claws, hoppers, clamping devices and other tooling. The fine-tuning process adopts the automatic fine-tuning method of the control system. After the fine-tuning is completed, the anti-floating pressure bar can automatically extend to limit the displacement of the track plate, and the degree of automation is high. (2) High operating efficiency: it realizes the integrated and continuous operation of self-compacting concrete mixing, transportation, track plate fine-tuning, and self-compacting concrete pouring, avoiding the tedious operations of manually installing fine-tuning claws, manually controlling fine-tuning claws for fine-tuning, installing traditional clamping devices, transporting self-compacting concrete, and manually disassembling traditional clamping devices, which can save a lot of time. In addition, the integration of various functions into one piece of equipment enhances the connection between various processes and ensures the continuity of construction. (3) Low operating cost: It can greatly reduce the manpower required for track plate fine-tuning and self-compacting concrete pouring, effectively reducing labor costs; in addition, after the use of the present invention, it can quickly move to the area to be operated without the need to manually install the traditional clamping device, which effectively reduces the time cost compared to the original; the anti-floating pull rod mechanism left on site by the present invention has a compact structure, low cost, and easy operation, which replaces the traditional clamping device and effectively reduces the economic cost. (4) Good operating effect: It can realize the self-identification of the track plate and the self-installation of the fine-tuning claws. The intelligent fine-tuning claws are coordinated through the master control. Compared with the current construction where multiple people cooperate to operate the traditional fine-tuning claws, it has higher fine-tuning sensitivity and accuracy, and can avoid construction failures caused by operator errors. Compared with the installation of traditional clamping devices in traditional processes, the present invention has less disturbance to the spatial state of the track plate after fine-tuning, and can better maintain the spatial position of the track plate after fine-tuning. (5) High safety: It effectively reduces manpower input during fine-tuning and pouring construction, and effectively avoids various safety risks caused by traditional manual operations. In addition, the track plate position recognition part of the present invention is automatically performed using an information processing program, which has higher accuracy than manual operation and can avoid unnecessary damage to the track plate during fine-tuning and pouring due to improper operation.

[0058] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that various modifications or variations that can be made by those skilled in the art without creative work on the basis of the technical solution disclosed in the present invention should be included in the scope of protection of the present invention.
