Description

Technical Field

[0001] The invention relates to the technical field of railway engineering construction equipment, in particular to a rolling device for railway roadbed construction filler. Background Art

[0002] During road construction, the roadbed needs to be compacted. The compacting device moves back and forth, and the heavy objects cause the roadbed soil to deform under pressure, thereby compacting and strengthening the roadbed to ensure the road's load-bearing capacity and stability and prevent potholes and bumps on the road surface. Therefore, professional rolling equipment is needed to fully compact the filler. Currently, existing railway roadbed rolling equipment often has the following shortcomings: The conversion between movement and working state is inconvenient. The existing rolling device is fixedly connected to the vehicle body, and the rolling rollers are used as wheels to achieve mobile rolling. In the non-operating state (such as when moving to a new site), the rolling rollers are in long-term contact with the ground, which can easily cause wear. The overall flexibility of the equipment is poor, especially it cannot be moved on railways with paved rails. The rolling method is single, and the rolling structure of existing rolling devices (such as rolling rollers) is mostly fixed, mostly cylindrical rolling rollers or triangular rolling rollers.

The beneficial effects are as follows: 1. Flexible switching between conventional rolling and impact rolling: By changing the structure to drive the support seat in the rolling structure to flip, the rolling roller can be switched between cylindrical rolling and impact rolling with support seat; when the support seat is stored in the embedded groove, the rolling roller is conventionally cylindrical, which is suitable for uniform compaction of conventional fillers such as sand and gravel; when the support seat is flipped and unfolded, the rolling roller will be lifted up due to the support seat contacting the ground when it rotates, and then rely on gravity to drop and hit the roadbed, forming an impact rolling effect, and enhancing the compaction degree of difficult-to-compact fillers such as clay; the rolling mode can be flexibly adjusted according to the material of the roadbed filler (such as sand, gravel, clay) and the compaction standard, to avoid insufficient compaction quality or excessive rolling problems caused by a single rolling method, and improve the stability and service life of the railway roadbed.

[0014] 2. Linked lifting of wheels and rolling rollers: The first screw in the support unit drives the sliding seat to move, driving the linkage arm to adjust the angle of the wheel frame, so that the wheel can be switched between raised (rolling roller on the ground during rolling operation) and lowered (wheel on the ground during transfer). During transfer, the rolling roller is suspended to avoid wear caused by long-term contact with the ground. At the same time, the wheel supports the movement of the equipment, improving maneuverability on complex terrain such as railroads. There is no need for complicated disassembly steps. The load-bearing state conversion of the rolling roller and wheel can be completed in minutes by simply driving the crank to operate the screw transmission, reducing construction preparation time and improving work efficiency.

[0015] 3. Unified control of the driving crank: The cross-shaped driving crank is adapted to the driving ports of the first screw and the second screw to achieve unified control of the moving state switching and the rolling mode adjustment, simplifying the operation process and reducing the difficulty of manual operation.

[0016] 4. The flipping angle of the support seat and the height of the rolling roller are controllable: when the second screw rotates, the moving distance of the linkage seat on the sliding shaft can be precisely controlled, and then the support seat is driven to flip to different angles through the support arm, thereby changing the effective rolling radius and impact force of the rolling roller; at the same time, the first screw adjusts the height difference between the wheel and the rolling roller, which can accurately control the pressure of the rolling roller on the roadbed and meet the parameter requirements of different compaction processes.

[0021] More specifically, through the design of the concave main frame 11 and the cross-shaped slide groove 4, the stable sliding and positioning of the support and replacement unit 14 are achieved, ensuring the structural rigidity of the equipment in the mobile and operating states. The driving crank 13 and the hexagonal driving port 10 of the first screw 143 are adapted to achieve quick connection and power transmission, which is easy and reliable to operate.

[0022] like Figure 2 and Figure 3As shown, further, the support and replacement unit 14 includes a baffle 141, an axis arm 142, a first screw 143, a sliding seat 144, a pair of locking rods 145, a wheel frame 146, a wheel 147 and a pair of linkage arms 148; the baffle 141 is detachably mounted on one end of the main frame 11, and a rubber pad is provided on the baffle 141, one end of the axis arm 142 is movably mounted on one end of the main frame 11, and the axis arm 142 can be flipped upward on the main frame 11, and the axis arm 142 cannot be flipped downward by being blocked by the blocking edge 101, and the first screw 14 3 is movably embedded in the left wall of the main frame 11, and the other end of the first screw rod 143 is movably inserted into the middle of the slide groove 4.

The other end of the locking rod 145 can be inserted into one end of the shaft arm 142 The wheel frame 146 is movably arranged on the lower wall of one end of the main frame 11, and the wheel frame 146 is symmetrically provided with a compensation groove 5, and the wheel 147 is movably arranged in the other end of the wheel frame 146, and the wheel 147 is close to the compensation groove 5, and one end of a pair of linkage arms 148 is movably arranged in the middle of the front and rear side walls of the sliding seat 144, and the other ends of the linkage arms 148 are respectively inclined to the left, and the other ends of the linkage arms 148 are respectively movably connected to the compensation groove 5 of the wheel frame 146, and the other ends of the linkage arms 148 can move along the compensation groove 5; the baffle 141 is blocked The blocking slide groove 4 and the shock absorption are carried out by rotating the first screw 143 to cause the sliding seat 144 to move under force, and drive the locking rod 145 to pass through the baffle 141. The locking rod 145 can be inserted into one end of the shaft arm 142 for locking, or the locking rod 145 can be detached from the shaft arm 142 to unlock. The unlocked shaft arm 142 can be flipped upward on the main frame 11. When the sliding seat 144 moves, the wheel frame 146 is flipped with the help of the inclined linkage arm 148, and the wheel 147 can be adjusted to the ground or lifted. The wheel 147 can be located above or below the lower wall of the rolling roller 21.

[0023] More specifically, the plug-in locking structure of the locking rod 145 and the shaft arm 142 is used to reliably fix the shaft arm 142 in a horizontal position, ensuring the stability of the equipment during movement. The threaded transmission of the first screw 143 and the sliding seat 144 is used to convert the rotational motion into linear motion, thereby realizing the coordinated lifting and lowering of the wheel 147 and the rolling roller 21, which is easy to operate and has high transmission efficiency. The design of the compensation groove 5 solves the problem of motion interference of the linkage arm 148 during the flipping of the wheel frame 146, and can ensure that after the locking rod 145 is unlocked, the shaft arm 142 can flip upward and the wheel 147 is still lifted.

[0024] like Figure 4As shown, further, the rolling structure 2 includes a rolling roller 21, a pair of supports 22 and two pairs of linkage components 23; a pair of embedded grooves 8 are symmetrically opened on the side wall of the rolling roller 21, and a connected starting port 9 is opened in the middle of the embedded groove 8, the pair of supports 22 are arc-shaped, one end of a pair of supports 22 is movably placed in one end of the embedded groove 8 through a pin shaft, a pair of supports 22 are movably embedded in the embedded groove 8, and the supports 22 are fit in the embedded groove 8, a pair of linkage components 23 are respectively arranged between the pair of supports 22 along the front and back, and the linkage component 23 is located in the middle of the rolling roller 21; the rolling roller 21 is rotated to roll the roadbed, and the support 22 is controlled to flip through the linkage component 23. When the support 22 is flipped open, the rolling roller 21 is rotated to increase the height and then descends to achieve the rolling and falling impact effect.

[0025] More specifically, through the flippable structural design of the support 22, the single rolling roller 21 can be switched between conventional rolling and impact rolling modes, thereby improving the adaptability and versatility of the equipment. The linkage assembly 23 adopts a combination structure of a universal joint connecting rod 232 and a support arm 233 to ensure that the support 22 is evenly stressed and moves smoothly during the flipping process to avoid jamming.

[0026] like Figure 4 、 Figure 5 and Figure 8 As shown, further, the linkage assembly 23 includes a linkage seat 231, a pair of universal shaft connecting rods 232 and a pair of support arms 233; the linkage seat 231 is movably arranged in the middle part of the rolling roller 21, a spiral hole is opened in the middle part of the two ends of the linkage seat 231, and a sliding port 6 is opened in the middle part of the linkage seat 231, one end of a pair of universal shaft connecting rods 232 are symmetrically arranged on the upper and lower sides of the middle part of the linkage seat 231, one end of a pair of support arms 233 are respectively fixedly arranged on the other end of the universal shaft connecting rod 232, and the other ends of the support arms 233 are respectively tilted and movable to pass through the starting port 9, and the other end of the support arm 233 is movably connected to the support seat 22; the linkage seat 231 is driven by the second screw 33 to move on the upper limit of the sliding shaft 32, and the support seat 22 is supported and flipped by means of the tilted support arm 233, and the flipping of the support seat 22 will drive the support arm 233 to flip and link with the help of the universal shaft connecting rod 232.

[0027] More specifically, the threaded transmission between the spiral hole and the second screw 33 converts rotational motion into linear motion, thereby realizing precise control of the flipping of the support 22. The cooperation between the sliding port 6 and the sliding shaft 32 ensures the precise movement trajectory of the linkage seat 231, prevents deviation and shaking, and improves the stability of the mechanism; the universal joint 232 solves the problem of multi-plane motion coordination during the flipping of the support 22, and can adapt to complex changes in motion trajectory; the design of the inclined support arm 233 converts the linear motion of the linkage seat 231 into the flipping motion of the support 22, thereby realizing effective force transmission and amplification, and reducing driving energy consumption.

[0028] like Figure 6 and Figure 7 As shown, further, the replacement structure 3 includes a pair of roller caps 31, a sliding shaft 32, a pair of second screw rods 33, a pair of gears 34 and a chain 35; the pair of roller caps 31 are respectively detachably buckled on the two ends of the rolling roller 21, and the roller caps 31 are fixed at equal distances by bolts, a sleeve is provided in the middle of the pair of roller caps 31, and the pair of roller caps 31 are respectively movably set between the other ends of the shaft arms 142 through the sleeves, and the two ends of the sliding shaft 32 are respectively detachably inserted between the sleeves of the roller caps 31, and the sliding shaft 32 cannot rotate, and the upper and lower side walls of the sliding shaft 32 are symmetrically provided with limiting grooves 7 that fit with the sliding opening 6, and the sliding shaft 32 movably passes through the sliding opening 6 in the middle of the linkage seat 231, and a pair of second screws 33 are respectively movably provided between the roller caps 31, and the second screws 33 are symmetrically located on both sides of the sliding shaft 32, and the two ends of the pair of second screws 33 respectively movably pass through the roller caps 31, and the pair of second screws 33 respectively movably pass through The spiral holes of the linkage seat 231 are rotationally connected, and a pair of second screw rods 33 are provided in the middle of both ends of the pair of second screw rods 33 with a driving port 10 corresponding to the driving crank 13. A pair of gears 34 are fixedly mounted on one end of the second screw rod 33 and are symmetrical to each other, and the chain 35 is movably mounted between the gears 34; the roller cap 31 is installed at both ends of the rolling roller 21 for transfer support, and by driving the crank 13 to drive one of the second screw rods 33 to rotate, the gear 34 and the chain 35 can be used to drive the other second screw rod 33 to rotate, thereby realizing the synchronous driving of the linkage seat 231 by two people to move, and performing labor-saving regulation. The rotation of the second screw 33 drives the linkage seat 231 to move on the sliding shaft 32, and the support arm 233 drives the support seat 22 to flip, and the driving crank 13 can be inserted into the first screw rod 143 and the second screw rod 33, and the crank 13 is driven to drive the first screw rod 143 and the second screw rod 33 to rotate.

[0029] More specifically, the detachable snap-on design of the roller cap 31 facilitates the assembly and disassembly of the rolling roller 21 and the exchange structure 3, thereby improving the equipment maintenance efficiency; the detachable plug-in and limit groove 7 design of the sliding shaft 32 and the roller cap 31 ensure the linear motion accuracy of the linkage seat 231, and avoid offset and shaking during the movement; the synchronous transmission mechanism of the gear 34 and the chain 35 realizes the synchronous drive of a pair of second screws 33, ensuring that the two sides of the support seat 22 are evenly stressed, the flipping action is coordinated, and two people can drive synchronously for labor-saving control.

[0030] Working principle: S1. First, the device is connected to the existing vehicle body through the adapter 12 on the main frame 11, and the vehicle body can be used to drive the device to move and turn; S2. During movement, the rolling roller 21 of the compaction structure 2 is supported and limited by the shaft arm 142 of the support and exchange unit 14. Since the roller caps 31 of the exchange structure 3 are symmetrically disposed at both ends of the compaction roller 21 and are movably connected to the shaft arm 142, the movement of the shaft arm 142 drives the compaction roller 21 and the roller cap 31 to rotate, thereby performing cylindrical rolling compaction. S3. In the cylindrical rolling roller 21, the locking rod 145 is inserted into the arm 142 at one end of the movable connection to lock the limit, prompting the arm 142 to maintain parallel docking with the main frame 11 in the frame structure 1; S4. When the rolling mode needs to be changed, the driving crank 13 is inserted into the driving port 10 at one end of the first screw 143 and rotated. This forces the sliding seat 144 in the linkage assembly 23 to move within the slide groove 4. The sliding seat 144 drives the locking rod 145 away from the shaft arm 142 to unlock the lock. The sliding seat 144 moves toward the adapter 12 to unlock the lock. At the same time, it drives the linkage arm 148 to slide within the compensation groove 5 of the wheel frame 146, keeping the wheel 147 lifted and the rolling roller 21 on the ground. S5. By driving the crank 13 to rotate the second screw 33 in the exchange structure 3, the two second screws 33 are rotated synchronously between the hole caps by means of the linkage of the gear 34 and the chain 35, driving the linkage seat 231 to be subjected to force and to be limited to the sliding shaft 32. The linkage seat 231 is subjected to force and slides on the sliding shaft 32 by means of the sliding opening 6, and drives the inclined support arm 233 to apply force to the support seat 22, causing the support seat 22 to flip open from the embedded groove 8. The support seat 22 will be located on the outside of the rolling roller 21, and the support arm 233 will pass through the starting opening 9 with the help of the universal shaft connecting rod 232 as the support seat 22 flips, so that the support arm 233 can be flipped and adjusted accordingly within the range of the starting opening 9, thereby providing stable supporting force for the support seat 22; S6. When the two supports 22 are symmetrically flipped open, the shaft arm 142 is also released from the locking rod 145 and unlocked. As the equipment moves, the rolling roller 21 is forced to rotate and is lifted by the curved supports 22 during rotation. When the supports 22 contact the ground, the rolling roller 21 is lifted by the upward flip of the shaft arm 142. As the rolling roller 21 rotates, it falls due to gravity and hits the ground to increase compaction. S7. When the equipment is being transported, when the support 22 contacts the ground, the rolling roller 21 drives the shaft arm 142 to rise. Since the locking rod 145 has been disengaged from the shaft arm 142 and unlocked, the first screw 143 can be rotated further to move the sliding seat 144 toward the transfer seat 12. The tilted linkage arm 148 is used to apply downward force to flip the wheel frame 146, which in turn drives the wheel 147 downward to contact the ground. The second screw 33 is then rotated by the driving crank 13 to reset the support 22 into the embedded groove 8. The rolling roller 21 then descends due to gravity. With the shielding of the stop edge 101, the shaft arm 142 is limited, and the rolling roller 21 is suspended in the air, moving with the help of the wheel 147. S8. That is, cylindrical rolling is performed when the rolling roller 21 contacts the ground, and the clockwise arranged supports 22 can be located on the left and right sides of the rolling roller 21, neither of which contacts the ground to achieve a suspended state. At this time, the second screw 33 is started to rotate, and the supports 22 are opened with little effort, and the operation will not be difficult due to the gravity of the rolling roller 21; when the supports 22 are flipped open, one of the supports 22 is forced to contact the ground to lift the rolling roller 21, and the wheel 147 can be lowered with the locking rod 145 unlocked, forcing the wheel 147 to contact the ground, and then the equipment is moved to rotate the rolling roller 21. When the support 22 is separated from the ground, the rolling roller 21 is suspended, which is convenient for resetting the support 22, thereby realizing the alternating transformation of the wheel 147, the rolling roller 21 and the support 22.

[0031] Since the arc-shaped support 22 in the equipment is arranged clockwise, it is necessary to pull or push the movement according to the actual equipment, and set the orientation of the two ends of the rolling roller 21, that is, the orientation of the support 22 is required. The support 22 is required to rotate with the rolling roller 21, so that the movable connection of the support 22 at one end of the embedded groove 8 first contacts the ground, and the other end of the flipped open support 22 contacts the ground before the rotation and lifting of the rolling roller 21 can be achieved.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or functional replacements made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
