Background Art

[0002] The vehicle-type rail reinforcement processing equipment developed by our company integrates multiple processes of the railway rail laser reinforcement alloying method into the same equipment, and realizes the construction work of each process along the way through the movement of the vehicle. The time relationship between the processes is controlled by the distance between the heating head, spray gun head and laser head, so as to complete the railway rail laser reinforcement alloying treatment efficiently and conveniently.

Long-term dust and high-humidity environments have a greater impact on the laser heads. Therefore, a set of mechanisms is needed to protect the laser head group when it is idle to improve its accuracy and service life. Utility Model Content

[0045] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0047] like Figure 1 and Figure 2 As shown, a laser head assembly lifting device 100 applied to a track reinforcement vehicle traveling along a track includes a gantry 101 and a laser head assembly 102 installed on the floor of the reinforcement vehicle. Figure 2 FIG. 1 is a schematic diagram of the structure of a reinforced vehicle, in which the laser group lifting system 100 is installed inside the reinforced vehicle, that is, the reinforced vehicle can transport the laser head group lifting system 100. During transportation, the laser head assembly 102 that can move left and right needs to be locked to avoid unnecessary displacement of the laser head assembly 102 during transportation.

[0048] The laser head assembly lifting system 100 is suitable for track-enhanced vehicles traveling along tracks, can be used in different working environments, and has a wide range of applicability. Moreover, the gantry 101 and the laser head assembly 102 are installed on the vehicle floor, and the overall structure is compact, does not occupy additional space, and uses space efficiently; the laser head assembly 102 is installed inside the reinforced vehicle, and the entire system can be transported, avoiding disassembly and assembly during transportation, saving transportation time and cost.

[0049] The laser head assembly 102 includes a connecting device 10 and a laser head group 20, and the laser head group 20 is arranged at the lower end of the connecting device 10. Due to the connection method between the connecting device 10 and the laser head group 20, the overall structure is simple and clear, and easy to install and maintain. Due to the simple structure, it is relatively easy to install and adjust the laser head assembly, reducing the complexity and cost of the installation process.

[0050] like Figure 3 As shown, a through hole 01 is opened on the floor 103 directly below the gantry 101, and the size of the through hole 103 is sufficient for the laser head group 20 to pass through. The laser head group 20 is arranged at the lower end of the connecting device 10. When in use, the entire assembly passes through the through hole 01 opened on the floor below the gantry 101, saving space and making the entire system compact and efficient. Moreover, the laser head group 20 can be conveniently lowered to the working position through the through hole 01 when needed, thereby improving the flexibility and applicability of the system.

[0051] The gantry 101 includes two columns 30 , two sets of lifting mechanisms 40 and a beam 50 ; the two sets of lifting mechanisms 40 are respectively arranged on the inner side of the columns 30 , and both ends of the beam 50 are connected to the lifting mechanisms 40 so that the beam 50 can rise and fall between the two columns 30 .

[0052] The two columns 30 provide a solid support to ensure the stability of the entire system. This structural setting allows the crossbeam 50 to rise and fall freely between the two columns 30, providing a stable support for the lifting of the laser head assembly 102.

[0053] The arrangement of the two lifting mechanisms 40 ensures the balanced up and down movement of the crossbeam 50 , thereby ensuring that the crossbeam 50 remains horizontal during the lifting process, thereby ensuring the stability and accuracy of the laser head assembly 102 .

[0054] The presence of the crossbeam 50 enables it to freely move longitudinally between the two columns 30, thereby improving the flexibility and applicability of the system. This flexible operation mode enables the laser head assembly 102 to operate at different heights to meet different track and operation requirements.

[0055] The design of connecting the two ends of the beam 50 to the lifting mechanism 40 improves the stability of the system. This connection method can effectively transmit force, so that the beam 50 remains stable during the lifting process, thereby ensuring the safe operation of the laser head assembly 102.

[0056] A horizontal slide rail g1 is disposed on the crossbeam 50 , and a slider g2 is disposed on the horizontal slide rail g1 . The upper end of the connecting device 10 is connected to the slider g2 , so that the laser head assembly 20 can move left and right along the horizontal slide rail g1 .

[0057] The laser head assembly 102 is connected to the slider g2 via the connecting device 10, and can move left and right along the horizontal slide rail g1, thereby realizing operations at different positions on the rail. This increases the operating range and flexibility of the system, allowing laser operations to cover a wider area.

[0058] Through the design of the horizontal slide rail g1 and the slider g2, the laser head assembly 102 can achieve precise left and right movement, so that precise laser operation can be performed at the required position, which improves the accuracy and efficiency of the operation.

[0059] Preferably, an intelligent control system can be introduced to realize automatic positioning and operation of the laser head assembly 102. For example, a sensor can be used to monitor the position of the workpiece on the track, and the position and parameters of the laser head assembly 102 can be automatically adjusted to realize automated laser operation.

[0060] In addition, the image recognition technology can be combined, and the laser head assembly 102 can identify the shape, size and position of the workpiece, and automatically adjust the laser operation parameters and position according to the recognition results to achieve more intelligent laser operation.

[0061] Furthermore, in the present invention, under the action of the lifting mechanism, the laser head group 20 can be lowered through the through hole 01 and located at a working position below the floor 103; in a non-working state, the laser head group 20 can be lifted into the reinforced vehicle body 200 on the inner side of the floor 103.

[0062] Through the lifting mechanism, the laser head group 20 can be flexibly switched between the working position and the non-working position. When laser operation is required, the laser head group 20 can be lowered to the working position below the floor to facilitate precise operation on the track. When the operation is completed or needs to be transferred, the laser head group 20 can be lifted into the carriage to ensure the safe storage and transportation of the equipment.

[0063] The laser head group 20 is lifted to the inside of the carriage, which effectively ensures the safety of the equipment when it is not in operation. This design can prevent the laser head group 20 from being exposed to the external environment and being hit, contaminated or damaged, thereby extending the service life of the equipment and reducing maintenance costs. In addition, the design of lifting the laser head group 20 to the inside of the carriage saves site space and improves site utilization. Especially in limited space working scenarios, this design can save space resources to the greatest extent and leave more space for other equipment or operations.

[0064] Furthermore, during transportation, the laser head assembly 20 is lifted into the interior of the carriage, which can effectively reduce the impact of external vibration, impact or other adverse environmental factors on the laser head assembly 20. This helps to reduce the transportation risk of the equipment and ensure the safe transportation of the equipment.

[0065] The laser head group 20 can be quickly lowered to the working position when needed to meet immediate operating requirements, thereby improving production efficiency. In the non-working state, the laser head group 20 is lifted into the interior of the carriage, does not occupy the working area, does not affect other production activities, and helps the overall production process to proceed smoothly.

[0066] Based on the above technical means, the laser head group 20 can be easily switched between the working position and the non-working position. When laser operation is required, the laser head group 20 can be quickly lowered to the working position below the floor to achieve precise laser operation. When the operation is completed or transportation is required, the laser head group 20 can be smoothly lifted into the carriage to ensure the safe storage and transportation of the equipment. This flexibility and adaptability allows the system to be adjusted according to the needs of different stages, improving the system's adaptability and scope of application.

[0067] To sum up, from the perspective of switchability between working and non-working states, this technical solution has the technical advantages of high flexibility, strong security, and optimized space utilization. It can also meet the work needs at different stages and improve the overall performance and reliability of the system.

[0068] More specifically, if Figure 4 and Figure 5 As shown, the connecting device 10 includes a connecting column 11 , a rotating assembly 12 , a limiting assembly 13 and a positioning assembly 14 .

[0069] The connecting column 11 is connected to the laser head assembly 20 via a rotating assembly 12 . The rotating assembly 12 can rotate the laser head assembly 20 180 degrees so that the laser head assembly 20 can operate on the two side tracks respectively.

[0070] The limiting assembly 13 limits the 180-degree rotation of the laser head assembly, and the positioning assembly 14 positions the first position and the second position of the laser head assembly 20 defined by the limiting assembly 13 .

[0071] The synergy of the connecting column 11 and the rotating assembly 12 allows the laser head group 20 to rotate 180 degrees on both sides of the track, which enables the laser head group 20 to operate in different directions and cover a wider area. For example, when it is necessary to process workpieces on both sides of the track, the laser head group 20 can adjust the angle quickly and accurately, thereby effectively improving the system's operational flexibility and coverage.

[0072] Moreover, time and labor costs can be saved by rotating the laser head group 20 without moving the entire system. This design also reduces the wear and tear of the equipment and energy consumption, thereby reducing maintenance and operating costs and improving the economic benefits of the system.

[0073] The setting of the limit assembly 13 and the positioning assembly 14 ensures the accurate positioning and stable operation of the laser head group 20. The limit assembly 13 limits the range of rotation of the laser head group 20 to avoid accidents caused by exceeding the safety range. The positioning assembly 14 ensures the accurate positioning of the laser head group 20 at different positions, improves the accuracy and efficiency of the operation, and reduces errors.

[0074] The rotating assembly 12 includes a connecting plate b1, a rotating component b2 and a base plate b3. The lower end of the connecting column 11 is fixed to the connecting plate b1. The rotating component b2 is arranged between the connecting plate b1 and the base plate b3. The upper end of the laser head group 20 is fixed to the lower side of the base plate b2.

[0075] The connecting plate b1 provides a stable supporting structure for fixing the connecting column 11 and the rotating component b2. The rotating component b2 is located between the connecting plate b1 and the bottom plate b3 and is the core component of the rotating assembly 12.

[0076] The upper end of the laser head group 20 is fixed to the lower side of the bottom plate b2. The rotating component b2 has a rotating function, so that the laser head group 20 can rotate 180 degrees around the fixed point of the connecting column 11 to achieve the direction adjustment of the laser head group 20.

[0077] The bottom plate b3 is located at the bottom of the rotating assembly 12 and is used to fix the rotating component b2 and provide stable support.

[0078] Through the above structure, the rotating assembly 12 can make the laser head group 20 rotate 180 degrees around the fixed point of the connecting column 11, thereby realizing the direction adjustment function of the laser head group 20, providing greater flexibility and accuracy for laser operations.

[0079] The limit assembly 13 includes a fixed limit block c1 on the lower side of the connecting plate b1 and a rotation limit block c2 on the upper side of the bottom plate b3. When the bottom plate b3 rotates 180 degrees, the rotation limit block c2 is limited by the fixed limit block c1. When the bottom plate b3 rotates, the rotation limit block c2 is limited by the fixed limit block c1, so that the rotation assembly 12 can only rotate 180 degrees between the fixed limit block c1 and the rotation limit block c2. Such technical means ensure that the laser head group 20 does not exceed the required range when rotating, avoiding accidental damage or unnecessary movement caused by excessive rotation. Therefore, the limit assembly 13 effectively limits the range of motion of the rotation assembly 12, improving the stability and safety of the system.

[0080] The positioning assembly 14 includes a fixed block d0 on the base plate b3 and a first fixed axis d1 and a second fixed axis d2 on the connecting plate b1. A positioning hole d3 is provided on the fixed block d0, and one of the first fixed axis d1 and the second fixed axis d2 can be inserted into the positioning hole d3. This technical means allows the relative position of the rotating assembly 12 to be adjusted between the connecting plate b1 and the base plate b3. When the first fixed axis d1 or the second fixed axis d2 is inserted into the positioning hole d3, the rotating assembly 12 is fixed in a specific position, thereby ensuring the precise positioning of the laser head group 20. By adjusting the position of the fixed axis, the rotation position of the laser head group 20 can be switched to meet different operating requirements. The design of this positioning assembly 14 improves the accuracy and stability of the system, and helps to ensure the accuracy and efficiency of laser operations.

[0081] like Figure 6 As shown, three sensors are installed on the column 30 on one side of the gantry 101, which are, from top to bottom, the upper limit position sensor p1, the zero position sensor p0 and the lower limit position sensor p2. The upper limit position sensor p1 is the sensor for the laser head group 20 to stop when it is at the uppermost end, the lower limit position sensor p2 is the sensor for the laser head group 20 to stop when it is at the lowermost end, and the zero position sensor p0 is the sensor for the laser head group 20 to stop when it is not in operation.

[0082] The preferred sensor may be applicable as follows: when the laser head group 20 reaches the uppermost position, the upper limit position sensor p1 will be triggered to stop the upward movement of the laser head group 20. This helps prevent the laser head group 20 from exceeding the safety range and avoids possible collisions or other unexpected situations.

[0083] The zero position sensor p0 is a sensor that is triggered when the laser head group 20 is in a non-operating state. It marks the reference position or initial position of the laser head group 20 and is usually triggered when the laser head group 20 is in the middle position. This helps the system restore the laser head group 20 to the standard position when necessary to ensure accuracy and consistency of operation.

[0084] When the laser head assembly 20 reaches the lowermost position, the lower limit position sensor p2 is triggered to stop the descending movement of the laser head assembly 20. This can effectively prevent the laser head assembly 20 from exceeding the safety range and avoid collision or other possible damage.

[0085] A fixing block r is provided at the upper end of the connecting column 11, and a plug hole r1 is provided on the fixing block r. A vertical plate f is provided on the crossbeam 50, and a movable locking pin f1 is provided on the vertical plate f. The locking pin f1 can be inserted into the plug hole r1 of the fixing block r to lock the laser head assembly 102 on the horizontal slide rail g1. In this way, the laser head assembly 102 will be firmly fixed on the horizontal slide rail g1, avoiding its movement or shaking due to vibration or other reasons during transportation, and ensuring the safe transportation of the laser head assembly 102. Thereby, the stability and safety of the laser head assembly lifting system are improved, and the laser head assembly 102 is protected from damage.

[0086] Furthermore, the connection device 10 in this embodiment also includes a rotation stabilization component, which includes a rotation guide ring and three connecting rods. The upper ends of the connecting rods are sleeved on the rotation guide ring, and the lower ends of the connecting rods are fixed on the bottom plate b3. When the bottom plate b3 rotates, the sleeve ring on the upper end of the connecting rod can slide along the rotation guide ring. This technical means can not only stabilize the rotation, but also strengthen the strength of the entire connection device 10.

It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
