Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, and in particular to an automatic rolling beam device with adjustable overhang. Background Art

[0002] When using long rail vehicles for collecting, changing, and unloading rails, the roller beam device is a special equipment for carrying long rails. Usually, there are several layers of roller beams, and each layer of roller beams is equipped with several rollers for carrying rails. When collecting or unloading any layer of rails, it is necessary to open the roller beams of the layer above it. The roller beam is usually a beam with a fixed axis at one end. It can be opened or closed by rotating horizontally 90°. The free end of the beam is stably supported by a fixed structure in the fully open or closed state. When in use, the roller beam needs to be manually pushed to open or close, and the fixing device at the free end of the roller beam is also manually operated. There are generally clear requirements for the overhang height of the free end of each layer of beams to match the height of the supporting structure. Therefore, necessary adjustments need to be made when installing the beam.

[0003] Traditional beams and swivels are welded together, with the shafts fixedly installed within the column compartments. Therefore, there is virtually no adjustment capability, and the overhang height can only be slightly altered by adjusting the assembly gaps between the swivels and shafts. These gaps are difficult to adjust and can easily shift during use, causing the beam to sag. Furthermore, due to the need to install a shaft, the column compartments of the welded structure require very high splicing precision, which is difficult to guarantee in terms of process and can easily lead to misaligned shaft positions. Over long-term use, the welded compartments are prone to deformation, causing changes in the overhang height of each layer of beams. The beams themselves lack the ability to adjust, resulting in permanent height changes. Furthermore, all operations are manual, and the beams are heavy, resulting in low efficiency and the risk of safety incidents. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and proposes an automatic roller beam device with adjustable overhang amount, which can reduce manual operations during the operation process, improve overall efficiency, and reduce the probability of safety accidents.

[0005] To achieve the above-mentioned object, the present invention provides an automatic roller beam device with adjustable overhang, comprising a horizontally arranged crossbeam and a locking column and a hinged column respectively used to fix the two ends of the crossbeam. A row of rollers for supporting long rails is provided on the top of the crossbeam; one end of the crossbeam is rotatably connected to the hinged column, and the other end rests on the locking column, and the locking column is provided with a locking mechanism for locking the crossbeam;

[0006] A layer plate for mounting the end of the beam is horizontally arranged on the hinged column, one end of the beam is rotatably connected to the layer plate by a rotating end head, and an end cover for fixing the rotating end head is arranged above the layer plate, and a connecting hole for rotatably connecting the rotating shaft of the rotating end head is vertically arranged on the end cover, one side of the end cover is mounted on the hinged column, and the top of the end cover is provided with a mounting boss on one side of the hinged column, and is detachably connected to the hinged column by a bolt passing through the mounting boss horizontally; the end cover is equipped with a plurality of adjustment pads of different thicknesses, and the adjustment pads are used to pad between the vertical part and the hinged column; a pushing lug is provided on one side of the rotating end head, and the pushing lug is equipped with a horizontally arranged rotating pushing cylinder, which pushes the pushing lug by the rotating pushing cylinder to realize the rotation of the beam.

[0007] In the above scheme: a resting platform for the overhanging end of the beam to rest on is horizontally provided on the locking column, the locking mechanism includes a lever, a locking pin and a locking cylinder respectively located at both ends of the lever, the locking pin is vertically provided below the resting platform, the bottom end of the locking pin rotates on the lever, the beam and the resting platform are both provided with a through hole for the locking pin to pass through, the top of the beam is provided with a groove, the roller is installed in the groove, a locking pin joint is provided in the groove of the beam corresponding to the locking pin, and the bottom of the locking pin joint is provided with a socket for the locking pin to be inserted;

[0008] The locking column is provided with a hinged support ear for hingedly connecting the middle part of the lever, which serves as the fulcrum of the lever. The locking column is provided with a hinged base for installing the locking cylinder. The protruding end of the locking cylinder is hinged and fixed to the other end of the lever through a pin shaft, and the cylinder body of the locking cylinder is connected to the hinged base through a pin shaft.

[0009] In the above solution, the locking cylinder is located on the side of the locking column away from the hinged column. Correspondingly, the locking column is provided with a through hole for the lever to pass through, and the extended end of the locking cylinder is positioned downward. In other words, the top of the locking cylinder is fixed to the locking column, reducing the vertical distance occupied by the locking mechanism and providing a reasonable arrangement.

[0010] In the above solution, a guide cylinder for guiding the locking pin is vertically disposed at the bottom of the platform. The locking pin is slidably connected within the guide cylinder, and a second notch is provided at the bottom of the guide cylinder to provide space for the lever. The lever is provided with a strip-shaped hole for its fulcrum shaft to pass through. The strip-shaped hole extends along the lever shaft, ensuring vertical movement of the locking pin, thereby allowing it to be inserted into the overhanging end of the beam.

[0011] In the above scheme: a support column for fixing the rotary push cylinder is vertically arranged on the vehicle body, and a hinged base is arranged on the support column corresponding to the rotary push cylinder. The two ends of the rotary push cylinder are rotatably connected to the push support ear and the hinged base through a vertically arranged pin shaft.

[0012] In the above solution: the rotary push cylinder is arranged on the side of the hinged column away from the crossbeam, and the hinged column is provided with a first notch for making way for the rotation of the push lug.

[0013] In the above solution: the top of each roller is located outside the groove of the crossbeam, and a roller support plate for mounting the roller is vertically arranged in the groove of the crossbeam;

[0014] The two ends of the roller are rotatably mounted on the roller support plate through the end of the rotating shaft, and the roller support plate is provided with a mounting hole for inserting the end of the rotating shaft;

[0015] Both ends of the roller are provided with outwardly protruding ribs, and the spacing between the ribs at both ends is exactly equal to the width of the bottom end of the long rail. The ribs are provided with circumferential detection notches, and both ends of the roller are provided with sensors for detecting the detection notches. The sensor detection output end is connected to the detection signal input end of the PLC, and the alarm output end of the PLC is connected to the alarm terminal signal input end.

[0016] In the above solution, there are three detection notches on the same rib, and the detection notches on the two end ribs are staggered by 60 degrees. The angles required for the two detection notches to rotate to the corresponding sensors are different. This can generate two detection signals, thereby improving detection accuracy.

[0017] In the above scheme: the mounting hole of the roller support plate is an upper-open mounting notch, and is closed by installing a pressure plate covering the mounting notch, and both ends of the pressure plate are fixed to the roller support plate by mounting screws.

[0018] In summary, the beneficial effects of the present invention are as follows: the use of a fixing device at the upper end of the beam realizes the function of arbitrarily adjusting the height of the overhanging end of the roller beam within a certain range by simply modifying or replacing parts during the initial installation and subsequent use. In addition, this structure is simple and effective, and the installation method is reasonable, which greatly reduces the difficulty of assembling and debugging the roller beam device, improves the accuracy and strength of the overall structure, and solves the problems of complex disassembly and maintenance in the later stage, and difficult construction in a small space. The provided rotating push cylinder and locking cylinder can realize remote control by the operator so that the operations of opening and closing the roller beam and locking the roller beam can be automatically performed, thereby improving the efficiency during operation and avoiding the safety issues of manual operation by the operator in the traditional solution, thus avoiding unnecessary accidents.

DETAILED DESCRIPTION

[0025] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0026] like Figures 1 to 5 As shown, an automatic roller beam device with adjustable overhang includes a horizontally arranged crossbeam 1, a locking column 2, and a hinged column 3 for fixing the ends of the crossbeam 1. A row of rollers 11 is provided on the top of the crossbeam 1 for supporting long rails 13. One end of the crossbeam 1 is rotatably connected to the hinged column 3, forming the hinged end, while the other end rests on the locking column 2, forming the overhanging end. The locking column 2 is provided with a locking mechanism for locking the crossbeam 1.

[0027] A horizontally mounted layer plate 3-1 for mounting the end of the crossbeam 1 is mounted on the hinged column 3. One end of the crossbeam 1 is pivotally connected to the layer plate 3-1 via a rotating head. An end cap 4 is mounted above the layer plate 3-1 to secure the rotating head. A rotating shaft is vertically mounted at both the upper and lower ends of the rotating head. The end cap 4 is vertically mounted with a connection hole for the rotating head's rotating shaft to pivotally connect. One side of the end cap 4 is mounted on the hinged column 3. The top of the end cap 4 is provided with a mounting boss 4-1, mounted on one side of the hinged column 3. The end cap 4 is removably connected to the hinged column 3 via bolts that pass horizontally through the mounting boss 4-1. The end cap 4 is equipped with multiple adjustment pads 6 of varying thicknesses. The adjustment pads 6 are used to cushion the gap between the end cap 4 and the hinged column 3. When installing the adjustment pads 6, they can be flush with the top of the mounting boss 4-1. The bolts also pass through the adjustment pads 6 to prevent them from falling. By switching the adjustment pads 6 of different thicknesses, the angle between the beam 1 and the hinged column 3 can be changed, so that the height of the fixed end of the beam 1 can be adjusted, thereby adjusting the overhang amount of the overhanging end of the beam 1, so that the beam 1 is in a horizontal state, ensuring the stable rotation of the beam 1, and thus opening.

[0028] A push lug 5 is provided on the side of the rotating end away from the crossbeam 1. The push lug 5 is equipped with a horizontally arranged rotary push cylinder 10. A support column 17 for fixing the rotary push cylinder 10 is vertically provided on the vehicle body 18. A hinged base is provided on the support column 17 corresponding to the rotary push cylinder 10. The two ends of the rotary push cylinder 10 are rotatably connected to the push lug 5 and the hinged base via a vertically arranged pin. The rotary push cylinder 10 is extended and retracted to drive the hinged end of the crossbeam 1 to rotate, so that the overhanging end of the crossbeam 1 moves away from the locking column 2, facilitating the collection and removal of the long steel rail 13 on the next layer of crossbeam 1. The rotary push cylinder 10 is an oil cylinder to increase the driving force. The rotary push cylinder 10 is provided on the side of the hinged column 3 away from the crossbeam 1. The hinged column 3 is provided with a first notch 3-2 to make way for the push lug 5 to rotate.

[0029] A resting platform 2-1 for the overhanging end of the beam 1 to rest on is horizontally provided on the locking column 2. The locking mechanism includes a lever 8, a locking pin 9 and a locking cylinder 7 located at both ends of the lever 8. The locking pin 9 is vertically provided below the resting platform 2-1. The bottom end of the locking pin 9 rotates on the lever 8. Both the beam 1 and the resting platform 2-1 are provided with through holes for the locking pin 9 to pass through. A groove is provided at the top of the beam 1, and the roller 11 is installed in the groove. A locking pin joint 16 is provided in the groove of the beam 1 corresponding to the locking pin 9, and a socket for the locking pin 9 to be inserted is provided at the bottom of the locking pin joint 16.

[0030] The locking column 2 is provided with an articulated lug for articulating the middle portion of the lever 8, serving as a fulcrum for the lever 8. The locking column 2 is also provided with an articulated base for mounting the locking cylinder 7. The protruding end of the locking cylinder 7 is hingedly fixed to the other end of the lever 8 via a pin, and the cylinder body of the locking cylinder 7 is connected to the articulated base via a pin. To save space, the locking cylinder 7 is positioned on the side of the locking column 2 away from the articulated column 3. Accordingly, the locking column 2 is provided with a through hole for the lever 8 to pass through. The protruding end of the locking cylinder 7 is positioned downward, meaning that the top of the locking cylinder 7 is fixed to the locking column 2. This reduces the vertical distance occupied by the locking mechanism and is a reasonable arrangement.

[0031] To ensure the vertical movement of the locking pin 9 and its insertion into the overhanging end of the beam 1, a guide cylinder 15 is vertically provided at the bottom of the support platform 2-1 to guide the locking pin 9. The locking pin 9 is slidably connected within the guide cylinder 15, and a second notch 15-1 is provided at the bottom of the guide cylinder 15 to make way for the lever 8. The lever 8 is provided with a strip-shaped hole 8-1 for its fulcrum to pass through. The strip-shaped hole 8-1 extends along the shaft of the lever 8.

[0032] The top of each roller 11 is positioned outside the groove of the crossbeam 1. A roller support plate 12 for mounting the roller 11 is vertically positioned within the groove of the crossbeam 1. Only one roller support plate 12 is positioned between two adjacent rollers 11, and both adjacent rollers 11 share a single roller support plate 12, saving space and achieving a compact structure. The rollers 11 are rotatably mounted on the roller support plates 12 at both ends via the ends of rotating shafts. The roller support plates 12 are provided with mounting holes 12-1 for the ends of the rotating shafts to be inserted into.

[0033] And each roller 11 is equipped with a rotating alarm mechanism. The rotating alarm mechanism includes a rib 11-1 protruding outward at both ends of the roller 11, and the spacing between the ribs 11-1 at both ends is exactly equal to the width of the bottom end of the long rail 13, and the ribs 11-1 at both ends are used to limit the long rail 13 to prevent the long rail 13 from moving left and right. A detection notch 11-2 is provided on the rib 11-1 in the circumferential direction, and a sensor 14 for detecting the detection notch 11-2 is provided on the roller support plate 12. The detection output end of the sensor 14 is connected to the detection signal input end of the PLC, and the alarm output end of the PLC is connected to the signal input end of the alarm terminal. The sensor 14 of this embodiment is an electromagnetic sensor. The PLC of this embodiment is also equipped with a wireless transceiver, and the alarm terminal is also equipped with a wireless transceiver, and the alarm terminal is installed in the cab. The PLC and the alarm terminal are connected by wireless transmission, so that the alarm signal is transmitted to the alarm terminal in the cab.

[0034] There are three detection notches 11-2 on the same rib 11-1, and the detection notches 11-2 on the ribs 11-1 at both ends are staggered by 60 degrees, and the angles required for the detection notches 11-2 at both ends to rotate to the corresponding sensors 14 are not equal. This can generate two detection signals, thereby improving the detection accuracy.

[0035] In this embodiment, there are three crossbeams 1 arranged at intervals in the upper and lower parts. The bottom crossbeam 1 is a fixed raceway beam, and both ends of the crossbeam 1 are fixed on the locking column 2 and the hinge column 3. The remaining crossbeams 1 are hinged to the hinge column 3.

[0036] Each beam 1 is loaded sequentially from bottom to top. Before loading, the adjustment pads 6 of all hinged beams 1 are replaced. Reducing the thickness of the adjustment pads 6 changes the angle between the beam 1 and the hinged column 3, thereby raising the height of the fixed end of the beam 1 and changing the overhang. This mechanism is installed on each layer of beams 1, allowing the overhang of each layer to be adjusted independently.

[0037] When opening, first drive the locking pin 9 downward through the locking cylinder 7 to unlock the beam 1. Then drive the rotary push cylinder 10 to rotate the beam 1 to one side, freeing up the space above the lower beam 1 for loading the long rail 13.

[0038] During loading, long rail 13 is pressed on roller 11 and fixed by the anchoring device of rail transport vehicle. After loading of lower layer crossbeam 1 is finished, upper layer crossbeam 1 is returned to its original position and locked, and adjusting plate 6 is replaced with original adjusting plate 6 simultaneously.

[0039] During transportation, if the locking state of the anchoring device fails, the long rail 13 will undergo longitudinal displacement. Under the action of friction, the roller 11 will rotate. When the detection notch 11-2 of the rib 11-1 on one side of the roller 11 rotates to the sensor 14 on the same side, the electromagnetic induction of the sensor 14 is interrupted, and the first detection signal is emitted. The roller 11 continues to rotate until the detection notch 11-2 of the rib 11-1 on the other side rotates to the other sensor 14. The electromagnetic induction of the other sensor 14 is also interrupted, and the second detection signal is emitted.

[0040] When the PLC receives detection signals from two sensors 14, it sends an alarm signal to the alarm terminal, which issues an alarm prompt. The alarm signal is triggered only when the detection signals from both sensors 14 are met. That is, the two detection signals are used as the basis for judgment to reduce the distortion and misjudgment caused by a single signal triggering the alarm, ensuring that the status of the roller 11 is truly identified. After the alarm terminal issues the alarm prompt, the safety personnel immediately drive the train to slow down and brake, and arrange for the operator to re-lock the long rail 13.

[0041] When unloading is required after transport, each beam 1 is unloaded in sequence from top to bottom. The unloading operation is the same as that of loading. First, replace the adjustment pad 6 with a smaller thickness. Then, the locking cylinder 7 drives the locking pin 9 downward to release the lock of the beam 1. Finally, the push cylinder 10 is rotated to move the beam 1 to the side, freeing up the space above the lower beam 1 for unloading the long rail 13.
