Description

[0001] This application belongs to the field of railway construction technology, and in particular relates to a joint-crossing mechanism. Background Technology

[0002] In the construction of high-speed railway bridges, crash barriers, as crucial safety protection structures, present unique challenges in their construction and maintenance. Due to the thermal expansion and contraction characteristics of concrete and the dynamic loads of the bridge, crash barriers must be designed with regularly distributed fracture structures. While these fractures ensure the long-term stability of the barrier, they create natural obstacles to the continuous operation of construction equipment. In traditional construction, whenever equipment reaches a fracture location, the work process must be interrupted, and temporary passages must be manually constructed. This not only reduces construction efficiency but also poses a risk of equipment falling.

[0003] In view of this, there is an urgent need for a cross-seam mechanism. Summary of the Invention

The third support frame, located on top of the tracked chassis, is connected to the first and second support frames respectively, and is used to hold the paving slab in its initial state.

[0011] In some possible implementation methods, the first support frame has a first limiting protrusion on the side adjacent to the crash barrier, for limiting the width of the crash barrier; and / or, The second support frame is provided with a second limiting protrusion on the side adjacent to the crash barrier, which is used to limit the width of the crash barrier.

It significantly improves construction efficiency. This innovative design not only solves the problem of low efficiency in traditional manual paving but also eliminates the safety hazards of high-altitude operations. Attached Figure Description

[0022] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linked," and "socketing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] like Figure 1As shown, this application provides a cross-joint mechanism including a paving slab 1, a traveling mechanism 2, and a telescopic swing assembly 3.

[0024] The paving slab 1 is used to be placed on the crash barriers 4 on both sides of the joint so that a walking road is formed between adjacent crash barriers 4.

[0025] Specifically, the paving slab 1 is plate-shaped, and its length can be a fixed length or a retractable plate structure.

[0026] It should be noted that the paving slab 1 includes: paving slab body 11, paving slab connector 12 and paving slab limiting member 13.

[0027] The paving slab body 11 is used to cross the gap, that is, the two ends of the paving slab body 11 overlap the adjacent crash barrier 4. In this way, the paving slab body 11 can be used as a road slab above the gap formed by the two crash barriers 4 so that the walking mechanism 2 can walk on it.

[0028] The paving slab connector 12 is located on one side below the middle area of ​​the paving slab body 11 and connects to the swing end. The shape of the paving slab connector 12 can be adjusted as needed, for example, it can be triangular, rectangular, or irregular in shape. The paving slab connector 12 serves to connect the swing end, and it also allows a certain distance between the swing end and the top surface of the crash barrier 4, so as to reserve the space required for the walking mechanism 2 to move.

[0029] Paving slab limiting members 13 are respectively installed at both ends of the paving slab body 11, and below the opposite sides of both ends, to limit the width of the crash barrier 4 when the paving slab body 11 crosses over the joint. The paving slab limiting members 13 are plate-shaped structures, perpendicularly connected to both ends of the paving slab body 11. In this way, the opposing paving slab limiting members 13 and the paving slab 1 can form a U-shaped structure, which can be inserted into the top of the crash barrier 4 to form a limit. When paving slab limiting members 13 are provided at both ends of the paving slab body 11, the top of the adjacent crash barrier 4 will be limited, thereby ensuring the stability of the traveling mechanism 2 during travel.

[0030] For example, if the paving slab 1 is a telescopic structure, the paving slab body 11 includes a first paving slab body and a second paving slab body, which are fitted together. The fitting position can be adjusted as needed; for example, the first paving slab body fits onto one end of the second paving slab body. In this way, the paving slab connector 12 can be located on the side of the first paving slab body, adjacent to the second paving slab body. The telescopic movement of the first and second paving slab bodies can be connected by an electric telescopic rod, i.e., the fixed end of the electric telescopic rod is connected to the bottom surface of the first paving slab body, and the telescopic end is connected to the bottom surface of the second paving slab body. By extending and retracting the electric telescopic rod, the position of the first paving slab body fitted onto the second paving slab body can be adjusted, thereby adjusting the overall length of the paving slab body.

[0031] The position of the electric telescopic boom can also be adjusted as needed. For example, when the chassis used by the walking mechanism 2 has two spaced tracks, the electric telescopic boom can be placed on the top surface of the first paving plate body and the second paving plate body. In other words, the position of the electric telescopic boom can be placed at any position that does not affect the movement of the walking mechanism 2.

[0032] Walking mechanism 2 is used to move on the crash barrier 4.

[0033] Specifically, the walking mechanism 2 includes a tracked chassis 21 for walking on the crash barrier 4, and the tracked chassis 21 is connected to the telescopic and rotating ends.

[0034] The tracked chassis 21 can have two sets of rotating wheels 211, one at the front and one at the rear. Each set consists of two opposing rotating wheels 211 arranged separately at both ends of the width of the crash barrier 4. In this configuration, the front set of rotating wheels 211 is the driving wheel, and the rear set is the driven wheel. The driving wheel rotates the driven wheel via the tracks. Alternatively, the tracked chassis 21 can have two wide-body rotating wheels 211, one at the front and one at the rear. In this configuration, the driving wheel rotates the driven wheel via the tracks. The movement of the tracked chassis 21 is achieved through these methods.

[0035] The center of the tracked chassis 21 can be used to arrange drive mechanisms, such as batteries and control systems. Furthermore, to facilitate the fixing of the rotating end, fixing plates 22 can be arranged on both sides of the tracked chassis 21. The outer side of the fixing plate 22 is connected to the rotating end, allowing the rotating end to rotate 360 ​​degrees around the fixing plate 22. The position of the rotating end on the fixing plate 22 can be adjusted as needed, and this application does not limit it.

[0036] It should be noted that, in order to perform engineering operations while crossing the joint, the walking mechanism 2 includes a first support frame 23, a second support frame 24 and a third support frame 25.

[0037] The first support frame 23 and the second support frame 24 are separately installed on both sides of the tracked chassis 21, and are used to limit the movement of the tracked chassis 21 in the width direction of the anti-collision wall 4 when it moves; wherein, the first support frame 23 is on the same side as the telescopic swing assembly 3.

[0038] The third support frame 25 is arranged on the top of the tracked chassis 21 and is connected to the first support frame 23 and the second support frame 24 respectively, and is used to hold the paving slab 1 in its initial state.

[0039] The first support frame 23 and the second support frame 24 are used to support the left and right sides of the tracked chassis 21, and the third support frame 25 is used to support the top of the tracked chassis 21.

[0040] In practical operation, the first support frame 23 and the second support frame 24 can prevent or reduce the swaying of the walking mechanism 2 during walking and working.

[0041] The telescopic swing assembly 3 is connected to the same side of the paving slab 1 and the traveling mechanism 2, respectively.

[0042] Among them, one end of the telescopic swing component 3 is a rotating end and the other end is a swing end. The rotating end is rotatably connected to the walking mechanism 2, and the swing end is connected to the paving plate 1 to adjust the swing angle of the paving plate 1.

[0043] Specifically, the telescopic swing assembly 3 includes a first motor 31 and a telescopic electric cylinder 32.

[0044] The first motor 31 is the rotating end of the telescopic swing assembly 3, and the first motor 31 is connected to the side of the walking mechanism 2; the telescopic electric cylinder 32 is connected to the first motor 31; wherein, driven by the first motor 31, the telescopic swing assembly 3 can rotate 360 ​​degrees relative to the walking mechanism 2.

[0045] The first motor 31 and the telescopic electric cylinder 32 are both conventional motors and electric cylinders.

[0046] The first motor 31 can control the rotation angle of the telescopic electric cylinder 32, thereby enabling the telescopic electric cylinder 32 to rotate at any angle. In other words, the first motor 31 can be used to achieve the suspension of the telescopic electric cylinder 32 at any angle.

[0047] Furthermore, the telescopic swing assembly 3 also includes a second motor 33 and a third motor 34.

[0048] The second motor 33 is rotatably connected to the end of the telescopic cylinder 32 away from the first motor 31; the third motor 34 is connected to the second motor 33, and the third motor 34 and the second motor 33 form the swing end of the telescopic swing assembly 3; the third motor 34 is rotatably connected to the paving slab 1.

[0049] The second motor 33 can adjust the angle between the telescopic cylinder 32 and the third motor 34 during the movement of the walking mechanism 2; the third motor 34 can adjust the angle between the telescopic cylinder 32 and the paving slab 1 during the movement of the walking mechanism 2.

[0050] It should be noted that the second motor 33 and the third motor 34 can increase the degree of freedom of the paving slab 1. In addition, the second motor 33 and the third motor 34 can be connected by a connecting rod. The function of the connecting rod is to increase the distance between the second motor 33 and the third motor 34, so as to make way for the forward direction of the first support frame 23 during the movement of the walking mechanism 2.

[0051] It should be noted that when the paving board connector 12 is long enough, the third motor 34 can be omitted as needed. That is, the third motor 34 is directly connected to the telescopic cylinder 32. Because the paving board connector 12 is long enough, omitting the third motor 34 allows the telescopic cylinder 32 to be directly connected to the second motor 33. The second motor 33 can still achieve 360-degree rotation of the paving board 1, thereby making way for the first support frame 23. However, this will sacrifice the flexibility of the paving board 1.

[0052] In fact, the paving slab connector 12 and the traveling mechanism 2 form a three-axis structure through three motors, which enables the paving slab 1 to rotate around the traveling mechanism 2 in all directions.

[0053] In one embodiment, the first support frame 23 is provided with a first limiting protrusion 231 on the side adjacent to the crash barrier 4, for limiting the width of the crash barrier 4; and / or, The second support frame 24 is provided with a second limiting protrusion on the side adjacent to the crash barrier 4, which is used to limit the width of the crash barrier 4.

[0054] Specifically, the first support frame 23 can be multiple cross-welded connecting rods, such as a rectangular structure. Multiple first limiting protrusions 231 can be provided at the bottom of the first support frame 23 as needed. The function of the first limiting protrusions 231 is to limit the position of the cross-joint mechanism when it is stopped. For example, when inkjet marking or drilling is performed while the cross-joint mechanism is stopped, good stability is required, and the first limiting protrusions 231 can effectively provide fixation.

[0055] It should be noted that the structures of the first limiting protrusion 231 and the second limiting protrusion can be the same. The following description uses the first limiting protrusion 231 as an example. The first limiting protrusion 231 can be a miniature electric push rod. The electric push rod is retracted in the non-operating state and extended in the operating state. A rubber block or suction cup can be provided at the end of the first limiting protrusion 231 away from the first support frame 23. When the first limiting protrusion 231 is in the operating state, it extends, so that the rubber block or suction cup at its front end abuts against the side wall of the anti-collision wall 4, forming a stable fixing structure. When the walking mechanism 2 is moving, the first limiting protrusion 231 is in the non-operating state, retracting to reduce its length and avoid affecting the movement of the walking mechanism 2.

[0056] Furthermore, the multiple first limiting protrusions 231 and second limiting protrusions respectively provided on the first support frame 23 and the second support frame 24 can also adjust the angle of the walking mechanism 2. That is, since the width of the third support frame 25 is greater than the width of the anti-collision wall 4, a certain distance is created between the first support frame 23 and the second support frame 24 and the anti-collision wall 4. In this case, the walking mechanism 2 will inevitably sway slightly when walking. If the walking mechanism 2 is not corrected when inkjet printing or drilling is required, there will be positional deviations in inkjet printing and drilling. At this time, by adjusting the extension and retraction length of the first limiting protrusions 231 and the second limiting protrusions, the posture correction of the walking mechanism 2 can be completed, thereby ensuring the accuracy of inkjet printing or drilling.

[0057] In one embodiment, an inkjet printer or a drilling machine 5 is provided on the second support frame 24; wherein, the inkjet printer is used to spray ink onto the side wall of the crash barrier 4 to form marking points; and the drilling machine 5 is used to drill holes in the marking points.

[0058] It should be noted that both the inkjet printer and the drilling machine 5 are existing structures, and this application has not made any improvements to them. The inkjet printer or the drilling machine 5 is fixed by the second support frame 24. The fixing method can be direct fixing with bolts, or the inkjet printer or the drilling machine 5 can be fixed by adding a fixing seat as needed.

[0059] Furthermore, the seam-crossing mechanism can first be equipped with an inkjet printer, which prints ink according to the set points during the seam-crossing movement. Next, the inkjet printer is replaced with a drilling machine 5, which moves in the reverse direction, thereby completing the drilling according to the marked points using the drilling machine 5.

[0060] In one embodiment, a slit-crossing mechanism further includes sensors and a control system.

[0061] The sensor is installed on the walking mechanism 2 to sense the gap crossing in the walking direction of the walking mechanism 2 and generate a sensing signal. The control system is connected to the sensor to receive the sensing signal, generate a gap crossing command based on the sensing signal, and send it to the walking mechanism 2 and the telescopic swing assembly 3 respectively, so that the walking mechanism 2 can adjust its speed in response to the gap crossing command, and the telescopic swing assembly 3 can adjust the paving slab 1.

[0062] Specifically, the sensor can be a laser sensor. After emitting a laser in the direction the forward-moving mechanism 2 travels, the laser sensor also receives the reflected laser light and determines the existence of the gap based on changes in the laser light. Furthermore, it can also determine the size of the gap using the laser light. This can be understood as using a sensor to perform laser scanning.

[0063] Next, the sensor will generate a sensing signal from the received scanning results and transmit it to the control system. The control system will then determine the size of the gap based on the sensing signal. Subsequently, it will send a gap-crossing command to each motor (first motor 31, second motor 33, and third motor 34). After receiving the gap-crossing command, each motor will perform the corresponding action, such as adjusting the rotation angle. Once each motor has completed the adjustment of the rotation angle, the laying adjustment of the paving slab 1 can be completed.

[0064] It should be noted that the slit-crossing commands sent by the control system to each motor in the application can be obtained by training the existing large model multiple times. For example, the historical slit-crossing dimensions can be input into the large model, and the large model can be used for reasoning to output the start-up time of the first motor 31, the second motor 33, and the third motor 34, as well as the rotation angle of the first motor 31, the second motor 33, and the third motor 34.

[0065] Understandably, the large model can be a neural network large model. This application has not made any adjustments to the structural framework of the large model, and the control system is a conventional computer control system.

[0066] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0067] Obviously, those skilled in the art should understand that the various units or steps of this application described above can be implemented using general-purpose computing devices. They can be centralized on a single computing device or distributed across a network of multiple computing devices. Optionally, they can be implemented using computer-executable program code, thereby storing them in a storage device for execution by a computing device, or fabricating them separately as individual integrated circuit modules, or fabricating multiple modules or steps into a single integrated circuit module. Thus, this application is not limited to any particular combination of hardware and software.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
