Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ballastless track body construction, and particularly relates to a double-block ballastless track body fine adjustment device. BACKGROUND

[0002] At present, when the track bed slab of the double-block ballastless track body is constructed, the track row method is used for construction, the track row refers to a track body frame formed by two track bodies and track parts using fasteners, and the track part is mainly a sleeper, and the track row method is a ballastless track body construction method in which a track row is hoisted into place by using hoisting and laying tools, and after fine adjustment and qualification, the track bed slab concrete is poured into the forming template. When the track row method is used to construct the track bed slab of the double-block ballastless track body, the precast sleeper is accurately positioned under the corresponding position of the track body by hoisting and fine adjustment of the track row, and then the cement concrete is poured, so that the fine positioning of the track row before pouring becomes a key control process. In actual construction, the fine adjustment accuracy of the track row is required to be very high, and the spatial position error (including the elevation error and the centerline error) of the sleeper before pouring is required to be less than ±0.5mm.

[0003] In the past, the fine adjustment of the track row was completed by the cooperation of the measurer and the worker. The measurer used the position error of each sleeper of the total station instrument, and then orally transmitted the error value to the worker, and the worker used the wrench to rotate the elevation screw rod and the centerline screw rod on the track row to eliminate the error. In the actual construction process, the defects of the above-mentioned track row fine adjustment construction method are obvious, including the following aspects: first, the demand for manpower is large, and 2 measurers and 4 to 6 workers are required to cooperate and operate; second, the adjustment speed is slow, and it takes 15 to 25 minutes to complete the adjustment of one track row; and third, the adjustment accuracy is low, and is easily affected by the manual oral transmission of the error and the manual operation error, resulting in unstable construction quality. Due to the above three defects and problems, the construction period of the ballastless track body construction is long, and the construction quality is low.

[0004] Therefore, a double-block ballastless track body fine adjustment device is urgently needed to solve the above problems. Content of the utility model

[0042] In combination Figures 1-5As shown, a double-block type ballastless rail body fine adjustment device comprises a plurality of lifting mechanisms 20, a plurality of horizontal pushing mechanisms 30, and a plurality of pushing pieces 40. The plurality of lifting mechanisms 20 are symmetrically arranged on both sides of two rail bodies 11 arranged on a plurality of sleepers 10 arranged along the railway extension direction. The plurality of horizontal pushing mechanisms 30 are arranged on both sides of the rail body 11 and fixedly connected with the lifting mechanisms 20 on the corresponding side. A cross beam 12 is fixedly arranged between the plurality of horizontal pushing mechanisms 30, and a pull beam 13 for clamping the two rail bodies 11 is slidably arranged on the inner side of the cross beam 12. The plurality of pushing pieces 40 are arranged on the inner side of the pull beam 13. One end of each pushing piece 40 is fixedly connected with the fixed end of the corresponding horizontal pushing mechanism 30, and the other end is connected with the sliding end of the corresponding horizontal pushing mechanism 30. The sliding end of each horizontal pushing mechanism 30 is fixedly connected with the rail body 11, so as to drive the two rail bodies 11 to be adjusted in the same direction in the horizontal direction.

[0043] In the above scheme, the lifting mechanisms 20 are symmetrically arranged on both sides of the two rail bodies 11 arranged on the sleepers 10 arranged along the railway extension direction, for adjusting the height of the rail body 11 and ensuring the accurate position of the rail body 11 in the vertical direction. The horizontal pushing mechanisms 30 are fixedly connected with the lifting mechanisms 20 on the corresponding side, and the two are connected with each other through the cross beam 12, for adjusting the rail body 11 in the horizontal direction. The working end of the horizontal pushing mechanism 30 is fixedly connected with the connecting piece 40, so that the action of the horizontal pushing mechanism 30 is directly transmitted to the connecting piece 40, and the horizontal position of the entire rail body 11 on the sleeper 10 is adjusted. The cross beam 12 is fixedly arranged between the plurality of horizontal pushing mechanisms 30, which provides the sliding rail body 11 for the pull beam 13 while limiting the sliding path of the pull beam 13, so as to ensure the accurate adjustment of the horizontal position of the rail body 11. The connecting piece 40 is arranged on the inner side of the pull beam 13, and the two ends thereof are fixedly connected with the working end of the corresponding horizontal pushing mechanism 30. When the horizontal pushing mechanism 30 acts, the connecting piece 40 moves, thereby pushing or pulling the rail body 11, so as to realize the horizontal adjustment of the rail body 11. The present application discards the traditional manual oral communication of the rail body 11 adjustment pitch and manual operation, and adopts the lifting mechanisms 20, the horizontal pushing mechanisms 30 and the control matched therewith to realize the fine adjustment of the rail body 11, so as to reduce the labor demand and improve the fine adjustment rate of the rail body 11 by using the mechanical automation mode.

[0044] The periphery of each lifting mechanism 20 is horizontally provided with a support 15 for fixing the corresponding horizontal pushing mechanism 30. The inside of the support 15 is provided with a limiting assembly 50, and the bottom of the limiting assembly 50 abuts against the top of the horizontal pushing mechanism 30 to form a limiting fit.

[0045] In the above scheme, when the lifting mechanism 20 lifts the horizontal pushing mechanism 30 and the support 15 connected thereto to a predetermined height, the working end of the horizontal pushing mechanism 30 starts to move in the horizontal direction. During the movement of the horizontal pushing mechanism 30, the top thereof keeps in contact with the bottom of the limiting assembly 50. On the one hand, it ensures that the horizontal pushing mechanism 30 always remains stable during movement, avoiding precision decline or damage due to shaking or deviation. On the other hand, it avoids the reaction force generated when the horizontal pushing mechanism 30 drives the connecting piece 40 to adjust the lateral displacement of the rail body 11, so as to prevent the horizontal pushing mechanism 30 from overturning upward or downward along the inner wall of the support 15, and ensure that the output end of the horizontal pushing structure and the connecting piece 40 are always in linearity, thereby ensuring the accuracy of the lateral adjustment of the rail body 11. In practice, the support 15 in the present application has an overall L-shaped structure. The horizontal section thereof is fixedly connected to the periphery of the outer cylinder 22 away from the rail body 11, and the vertical section is arranged at the bottom of the horizontal section. The horizontal section and the vertical section of the support 15 are provided with a missing area for fixing the horizontal pushing mechanism 30.

[0046] The lifting mechanism 20 comprises an inner cylinder 21, an outer cylinder 22, a nut 23, a first speed reducer motor 24 and a first drive motor 25. The inner cylinder 21 is vertically fixedly arranged outside the rail body 11 and between adjacent sleepers 10. The outer cylinder 22 is slidingly arranged on the periphery of the inner cylinder 21, and the periphery of the outer cylinder 22 is fixedly connected to the top of the support 15. The nut 23 is fixedly arranged on the top of the inner cylinder 21. The first speed reducer motor 24 is arranged on the top of the outer cylinder 22. The output end of the first speed reducer motor 24 extends to the bottom of the inner cylinder 21 through the outer cylinder 22 and the nut 23 in sequence. The first drive motor 25 is horizontally arranged on one side of the first speed reducer motor 24. The output end of the first drive motor 25 is fixedly connected to the input end of the first speed reducer motor 24, for driving the vertical displacement of the horizontal pushing mechanism 30.

[0047] In the above scheme, when it is necessary to lift the horizontal pushing mechanism 30, the first drive motor 25 is started, and the output end thereof drives the first speed reducer motor 24 to rotate. The first speed reducer motor 24 converts the high-speed low-torque power into low-speed high-torque power, and then the output end thereof cooperates with the nut 23 to convert the rotary motion into linear motion, driving the outer cylinder 22 to move up and down along the inner cylinder 21. Since the periphery of the outer cylinder 22 is fixedly connected to the top of the support 15, the support 15 and the horizontal pushing mechanism 30 fixedly arranged on the support 15 will also move up and down with the movement of the outer cylinder 22, thereby adjusting the relative position of the horizontal pushing mechanism 30 and the rail body 11 in the vertical direction.

[0048] The combination design of the inner cylinder 21, the outer cylinder 22, the nut 23, the first reduction motor 24 and the first driving motor 25 in the present application makes the lifting mechanism 20 compact in structure and small in floor area, facilitating installation and use in the limited space of the railway rail body 11. Through the reduction effect of the first reduction motor 24, the rotational movement of the output end thereof can be more stable, thereby avoiding excessive impact and vibration during lifting.

[0049] The horizontal pushing mechanism 30 comprises a sliding box 31, a fixed block 32, a screw rod 33, a second reduction motor 34 and a second driving motor 35. The sliding box 31, which is internally hollow and open at both ends, is horizontally arranged at the bottom of the support 15, and the top of the sliding box 31 abuts against the bottom of the limiting assembly 50. One end of the sliding box 31 close to the rail body 11 is fixedly connected with one end of the pull beam 13. The fixed block 32 is arranged in the interior of the sliding box 31, and the two ends in the width direction of the fixed block 32 are fixedly connected with the two side inner walls of the sliding box 31. The screw rod 33 is arranged in the interior of the sliding box 31 and passes through the fixed block 32. The screw rod 33 is threadedly connected with the fixed block 32, and one end of the screw rod 33 close to the rail body 11 is threadedly connected with the connecting piece 40. The second reduction motor 34 is horizontally arranged in the interior of the sliding box 31 on any one side away from the rail body 11. The output end of the second reduction motor 34 passes through the middle part of the fixed block 32 and is screwed with one end of the screw rod 33 away from the rail body 11. The second driving motor 35 is vertically arranged in the interior of the support 15 away from the rail body 11, and the output end of the second driving motor 35 is fixedly connected with the input end of the second reduction motor 34.

[0050] In the above scheme, the sliding box 31 is horizontally arranged at the bottom of the support 15 as the main structure of the horizontal pushing assembly. The fixed block 32 is arranged in the interior of the sliding box 31 for fixing and supporting the screw rod 33. The screw rod 33 is arranged in the interior of the sliding box 31 and passes through the fixed block 32, and is threadedly connected with the fixed block 32 to form a screw rod transmission mechanism. One end of the screw rod 33 close to the rail body 11 is threadedly connected with the connecting piece 40 for pushing the connecting piece 40 to move. The second reduction motor 34 is horizontally arranged in the interior of the sliding box 31 away from the rail body 11. The output end of the second reduction motor 34 passes through the middle part of the fixed block 32 and is screwed with one end of the screw rod 33 away from the rail body 11 for driving the screw rod 33 to rotate. The second driving motor 35 is vertically arranged in the interior of the support 15 away from the rail body 11. The output end of the second driving motor 35 is fixedly connected with the input end of the second reduction motor 34 for providing power.

[0051] Alternatively, the second driving motor 35 and the second speed reducer 34 can be arranged on the slide box 31 on either side of the rail body 11, or on both sides of the rail body 11. When the second driving motor 35 and the second speed reducer 34 are arranged on the slide box 31 on one side of the rail body 11, the slide box 31 on the opposite side is fixedly connected to the screw rod 33 and the top piece inside, so that when the screw rod 33 is driven to rotate by the second driving motor 35 and the second speed reducer 34, the slide box 31 without the second driving motor 35 and the second speed reducer 34 is driven to slide towards the side close to the rail body 11, and at this time, the folded edge of the slide box 31 away from the rail body 11 can abut against the bottom of the limiting assembly 50 to prevent the rail body 11 from being excessively displaced;

[0052] When the rail body 11 needs to be pushed horizontally, the second driving motor 35 is started, and the output end drives the second speed reducer 34 to rotate. The speed reducer converts high-speed low-torque power into low-speed high-torque power, which is then transmitted to the screw rod 33. Since the screw rod 33 is threadedly connected to the fixed block 32, the rotational movement of the screw rod 33 is converted into linear movement, which drives the connecting piece 40 threadedly connected thereto to move along the slide box 31. During the movement of the connecting piece 40, the slide box 31 is connected to the support 15, the draw beam 13 and other structures, thereby realizing the horizontal pushing adjustment of the rail body 11.

[0053] The limiting assembly 50 includes a limiting box 51, a first limiting rod 52 and a second limiting rod 53. The limiting box 51 is fixedly arranged inside the support 15 and located on the top of the slide box 31. The bottom of the limiting box 51 is slidably connected to the top of the slide box 31. One end of the first limiting rod 52 horizontally extends into the interior of the limiting box 51, and the other end penetrates through the side of the support 15. A limiting groove is formed in the radial direction of the first limiting rod 52 close to the limiting box 51. One end of the second limiting rod 53 vertically penetrates through the exterior of the slide box 31, and the other end vertically extends into the interior of the slide box 31 and is embedded in the limiting groove to form a limiting fit.

[0054] In the above scheme, the limiting box 51 is fixedly arranged inside the support 15 and located on the top of the slide box 31, serving as the main structure of the limiting assembly 50 and being used to accommodate and support the first limiting rod 52 and being connected to the slide box 31 through sliding connection. One end of the first limiting rod 52 horizontally extends into the interior of the limiting box 51, and the other end penetrates through the side of the support 15, thereby providing limiting action in the horizontal direction. A limiting groove is formed in the radial direction of the first limiting rod 52 close to the limiting box 51, thereby cooperating with the second limiting rod 53. One end of the second limiting rod 53 vertically penetrates through the exterior of the slide box 31, and the other end vertically extends into the interior of the slide box 31 and is embedded in the limiting groove of the first limiting rod 52 to form a limiting fit, thereby providing limiting action in the vertical direction.

[0055] In the present application, the limiting box 51 is fixed to the horizontal section of the support 15 through the first limiting rod 52 and the second limiting rod 53, preventing the limiting box 51 from overturning upward or downward along the length direction of the slot of the support 15, thereby realizing the limiting of the sliding box 31 in both horizontal and vertical directions, and ensuring the stability and safety of the sliding box 31, the transverse pushing assembly and the lifting mechanism 20 connected thereto during movement.

[0056] The pull beam 13 is provided with a mounting slot 131 at both ends along the width direction thereof for adapting the rail body 11, and the mounting slot 131 is provided with the cushion block body 14 between the rail body 11.

[0057] In the above scheme, the installation of the mounting slot 131 enables the rail body 11 to be accurately placed therein, thereby ensuring the stability and position accuracy of the rail body 11 and avoiding installation errors and stress concentration that may be caused by direct welding or bolt connection. The cushion block body 14 is arranged between the mounting slot 131 and the rail body 11, which on the one hand adjusts the height of the rail body 11 to ensure that the rail body 11 reaches the required height, and on the other hand absorbs the vibration and impact force generated during the operation of the first drive motor 25, the first speed reducer 24, the second drive motor 35 and the second speed reducer 34; additionally, it provides additional support and stability for the connection between the rail body 11 and the pull beam 13, ensuring that the position of the rail body 11 in the mounting slot 131 will not be deviated due to external force.

[0058] The cushion block body 14 includes a first cushion block 141 and a second cushion block 142 which are identical in structure, one side of each of the first cushion block 141 and the second cushion block 142 is a horizontal surface and the other side is an inclined surface; the horizontal surface of the first cushion block 141 abuts against the inner side surface of the rail body 11, the horizontal surface of the second cushion block 142 abuts against the slot wall of the mounting slot 131, the inclined surface of the first cushion block 141 and the inclined surface of the second cushion block 142 are complementary to each other and form a rectangular structure.

[0059] The first cushion block 141 has a horizontal surface and an inclined surface. The horizontal surface of the first cushion block 141 is in contact with the inner side surface of the rail body 11, ensuring the stability and position accuracy of the rail body 11 in the installation groove 131. The design of the horizontal surface provides uniform support force, preventing the rail body 11 from tilting or shifting during installation. The horizontal surface of the second cushion block 142 is in contact with the groove wall of the installation groove 131, ensuring the stability and position accuracy of the cushion block body 14 in the installation groove 131. This design not only provides additional support for the rail body 11, but also prevents the cushion block body 14 from moving or tilting during installation by its close contact with the groove wall of the installation groove 131. The inclined surface of the first cushion block 141 is complementary to the inclined surface of the second cushion block 142, forming a rectangular structure. The design of the inclined surface allows the cushion block body 14 to adapt to different directions and sizes of force, enhancing its adaptability and durability, and the complementarity of the inclined surfaces makes the cushion block body 14 easier to install and disassemble, reducing installation time and cost.

[0060] In an embodiment, the connecting piece 40 in the present application can be a threaded sleeve, which is sleeved on the corresponding end of the screw rod 33 and fixedly connected by a pin. The thread direction on the inner wall of the connecting piece 40 is opposite or the same as the thread direction on the surface of the screw rod 33.

[0061] In the above scheme, when a rotating force is applied to the connecting piece 40, due to the opposite direction of the threads, the connecting piece 40 will move along the axial direction of the screw rod 33. If the rotating direction is such that the connecting piece 40 is "tightened" relative to the screw rod 33, the connecting piece 40 will move towards the other end of the screw rod 33, thereby moving the rail body 11 to one side; conversely, if the rotating direction is "loosening", the connecting piece 40 will move towards one end of the screw rod 33, thereby moving the rail body 11 to the other side. And due to the thread friction between the screw rod 33 and the connecting piece 40, when the connecting piece 40 is tightened to a certain extent, it will be self-locked on the screw rod 33, preventing loosening due to external vibration or impact, thereby ensuring the stability and safety of the lateral fine adjustment of the rail body 11.

[0062] In the present application, the second drive motor 35 and the second speed reduction motor 34 are arranged on the sliding box 31 on either side of the rail body 11, or can be arranged on the sliding boxes 31 on both sides of the rail body 11.

[0063] As Figure 3As shown, the preferred embodiment of this application is that when the second drive motor 35 and the second reduction motor 34 are mounted on the slide box 31 located on one side of the rail body 11, the thread direction of the connecting member 40 is opposite to the thread direction of the screw 33. Since the internal screw 33 of the slide box 31 is fixedly connected to the top fitting, when the second drive motor 35 and the second reduction motor 34 drive the screw 33 to rotate, the screw 33 will rotate with the connecting member 40, which will drive the slide box 31 without the second drive motor 35 and the second reduction motor 34 to slide closer to the rail body 11. At this time, the flange of the end of the slide box 31 away from the rail body 11 can abut against the bottom of the limiting component 50 to prevent the rail body 11 from being over-displaced.

[0064] like Figure 4 As shown, the feasible solution of this application is that when the second drive motor 35 and the second reduction motor 34 are simultaneously installed on the slide box 31 located on one side of the rail body 11, the thread direction of the connector 40 is the same as the thread direction of the screw 33. Since the screws 33 are all fixedly installed in the fixing block 32 inside the slide box 31, the connector 40 will slide along the axial length direction of the screw 33. During this process, the connector 40 abuts against the pull beam 13, causing the pull beam 13 to move with the slide box 31, thereby driving the rail body 11 to move and realizing the lateral fine adjustment of the rail body 11.
