Detailed Implementation

[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 4-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] A device for longitudinal conveying of irregularly shaped steel rails, (e.g.) Figure 4 As shown, it has a fixed base 1, which is slidably connected to a translational base 2, and the translational base 2 is driven to translate by a gear transmission mechanism.

[0032] It should be noted that the gear transmission mechanism possesses high transmission accuracy and stability. Its design effectively reduces vibration during transmission, thus preventing damage or misalignment of irregularly shaped rails during transport. The gear transmission mechanism also boasts high load-bearing capacity, meeting the heavy-load requirements of longitudinal transport of irregularly shaped rails. Given the potentially complex cross-sectional shape and dimensions of irregularly shaped rails, this device, driven by the gear transmission mechanism to the translation base, better adapts to rails of different shapes and sizes, achieving stable and reliable transport. The gear transmission mechanism has a relatively simple structure, facilitating maintenance and repair. When repair or component replacement is required, it can be easily disassembled and replaced, reducing maintenance costs and time. The device, driven by the gear transmission mechanism to the translation base, can easily extend the transport distance and load-bearing capacity. Simply adding appropriate racks and transmission mechanisms enables long-distance, high-load transport of irregularly shaped rails. The gear transmission mechanism has high transmission efficiency, reducing energy loss and improving energy utilization efficiency. Due to its high transmission accuracy and stability, it reduces additional energy consumption caused by transmission errors and vibration, thus achieving energy conservation and consumption reduction.

[0033] The top of the translation base 2 is equipped with a vertically downward lifting hydraulic cylinder 6. The lifting hydraulic cylinder 6 is fixedly connected to the lifting base 3 at its end and drives the lifting base 3 to rise and fall.

[0034] It should be noted that the lifting hydraulic cylinder 6 provides precise lifting control, ensuring accurate vertical movement of the lifting base 3, which is crucial for conveying irregularly shaped steel rails requiring high-precision positioning. The hydraulic cylinder uses oil to transmit power, reducing friction and vibration between mechanical parts, making the lifting process smoother and avoiding potential damage to the irregularly shaped steel rails caused by shaking or vibration. The hydraulic system has a high load-bearing capacity, easily handling the weight of irregularly shaped steel rails, ensuring stability and safety during lifting. The design of the lifting hydraulic cylinder 6 allows it to adapt to irregularly shaped steel rails of different weights and sizes, meeting diverse conveying needs. The hydraulic system has a fast transmission speed and rapid response, enabling the lifting base 3 to be raised and lowered in a short time, improving work efficiency. The lifting hydraulic cylinder 6 has a relatively simple structure, is easy to maintain and repair, and can be quickly located and repaired in case of failure, reducing downtime. Hydraulic components have a long service life, generally requiring longer maintenance cycles, reducing maintenance costs. The design of the lifting hydraulic cylinder 6 considers safety factors, such as overload protection and pressure limiting, ensuring no unexpected situations occur during lifting. The hydraulic system has a simple and reliable working principle and can operate stably in harsh working environments, thus improving the reliability of the entire conveying device.

[0035] The lifting base 3 is equipped with a clamping hydraulic cylinder 7. The end of the clamping hydraulic cylinder 7 is connected to the gripper 13 via a connecting rod 12 and drives the gripper 13 to perform opening and closing actions.

[0036] It should be noted that the hydraulic transmission system generates enormous pressure, giving the clamping hydraulic cylinder 7 a powerful clamping force. This ensures that the gripper 13 firmly holds the irregularly shaped rail, preventing it from slipping or falling off during transport. The stability of the hydraulic system allows the gripper 13 to maintain a stable clamping force when holding the irregularly shaped rail, without fluctuations due to external factors, thus ensuring a smooth and safe transport process. Through an advanced hydraulic control system, precise control of the opening and closing speed and clamping force of the gripper 13 can be achieved. This precise control capability allows the gripper 13 to adaptively adjust according to different sizes and shapes of irregularly shaped rails, ensuring the accuracy and reliability of clamping. The adjustability of the hydraulic system allows the opening and closing action of the gripper 13 to be flexibly adjusted as needed. For example, when clamping large or heavy irregularly shaped rails, the clamping force and opening and closing speed can be appropriately increased; while when clamping small or light irregularly shaped rails, the clamping force and opening and closing speed can be decreased to achieve more precise operation. Similarly, the hydraulic system's high transmission speed and rapid response enable the gripper 13 to complete its opening and closing action in a short time, thereby improving the overall operating efficiency of the conveying device. Because the gripper 13 can open and close quickly, the waiting time for irregularly shaped rails during conveying is reduced, further improving production efficiency. The clamping hydraulic cylinder 7 and connecting rod 12 have a relatively simple structure, are easy to maintain and repair, and can be quickly located and repaired in case of malfunction, reducing downtime. This design is adaptable to irregularly shaped rails of different sizes, shapes, and weights, demonstrating strong versatility.

[0037] In the above embodiments, preferably, the fixed base 1 is a horizontal block structure, and the top of the horizontal block and the vertical sidewall are respectively provided with a horizontal slide rail slider mechanism 8.

[0038] It should be noted that the fixed base 1 adopts a horizontal block structure, which provides a stable support surface and enhances the stability of the entire device. This structure makes the device less prone to deformation or instability when subjected to heavy loads or vibrations. The transverse slide rail slider mechanism 8, installed at the top and vertical sidewalls of the fixed base 1, further improves the structural stability. The slide rail slider mechanism can withstand large lateral loads, ensuring the smoothness and safety of the translation base 2 and the lifting base 3 during movement.

[0039] In the above embodiments, the fixed base 1 is further slidably connected to the translation base 2 by at least two sets of transverse slide rail slider mechanisms 8, and the transverse slide rail slider mechanism 8 provides linear guidance for the translation of the translation base 2.

[0040] It should be noted that the transverse slide rail slider mechanism 8 typically employs a high-precision guide rail and slider design, ensuring high-precision positioning of the translation base 2 and the lifting base 3 during movement. This is crucial for conveying devices requiring precise control of the position of irregularly shaped steel rails. The slide rail slider mechanism is made of wear-resistant materials, reducing friction and wear and extending its service life. Simultaneously, the design of the slide rail slider mechanism effectively distributes and transmits force, ensuring stable operation of the entire system.

[0041] In the above embodiments, the preferred embodiment is: (in combination with) Figure 6 The translation base 2 is a right-angled plate structure; the gear transmission mechanism consists of a motor 5, a gear 11, and a rack 10; the motor 5 is vertically installed on the outside of the vertical plate of the translation base 2, and the motor shaft of the motor 5 passes horizontally through the vertical plate and then the gear 11 is fixedly installed. The gear 11 meshes with the rack 10, and the rack 10 is horizontally set and fixedly installed on the vertical side wall of the fixed base 1; the aforementioned motor 5 drives the gear 11 to rotate, and the gear 11 meshes with the rack 10 to drive the translation base 2 to translate.

[0042] It should be noted that the translation base 2 adopts a right-angled plate structure. This design makes the device more compact and enables efficient transport of irregularly shaped rails within a limited space. The motor 5 is vertically mounted on the outside of the vertical plate of the translation base 2. The motor shaft passes horizontally through the vertical plate and a gear 11 is fixedly mounted thereafter, meshing with a rack 10 fixed to the vertical sidewall of the fixed base 1. This layout makes full use of the device's space, making the entire device more compact and easier to install and maintain. The gear transmission mechanism features high transmission accuracy and low error. Due to the structural characteristics and working principle of the gear transmission mechanism, the translation base 2 operates smoothly during movement, reducing potential damage to irregularly shaped rails caused by vibration or shaking. The motor 5, as the power source, provides sufficient driving force to drive the gear 11 to rotate, which in turn drives the translation base 2 to move through the rack 10. This design allows the device to carry heavier irregularly shaped rails, meeting the needs of heavy-duty transport. The meshing parts between gear 11 and rack 10 are easy to lubricate and clean in order to maintain their good working condition and extend their service life.

[0043] In the above embodiment, further: a hydraulic cylinder fixing plate 4 is fixedly installed on the top horizontal surface of the translation base 2. The hydraulic cylinder fixing plate 4 is a horizontally extended plate structure. The vertically downward lifting hydraulic cylinder 6 is fixedly installed on the plate extending to the outside of the translation base 2. The end of the lifting hydraulic cylinder 6 is fixedly connected to the lifting base 3 through a connecting plate 16.

[0044] It should be noted that the hydraulic cylinder fixing plate 4, as the supporting structure for the lifting hydraulic cylinder 6, provides a stable installation base through its horizontally extended plate design. By fixing the hydraulic cylinder fixing plate 4 to the top horizontal surface of the translation base 2, the vertical installation and stable operation of the lifting hydraulic cylinder 6 are ensured. The lifting hydraulic cylinder 6, as a power source, provides sufficient driving force to drive the lifting base 3 in lifting motion, enabling the device to bear heavy loads and meet the needs of heavy-duty lifting. The hydraulic system features precise transmission and convenient control; by adjusting the pressure and flow of the hydraulic system, the lifting speed and position of the lifting base 3 can be precisely controlled. The piston rod of the lifting hydraulic cylinder 6 extends or retracts smoothly under hydraulic pressure, driving the lifting base 3 in smooth lifting motion. This design reduces potential damage to the device and load caused by motion impact. The structures of the hydraulic cylinder fixing plate 4 and the lifting hydraulic cylinder 6 are relatively simple and clear, facilitating maintenance and repair, and making inspection and replacement easy.

[0045] In the above embodiments, preferably, the lifting base 3 is a horizontally placed "T-shaped" structure. The "T-shaped" lifting base has a larger support area compared to other shapes. A larger support area means better stability, reducing swaying and tilting during lifting and ensuring load safety. The "T-shaped" design typically places the center of gravity at a lower position, which helps increase the stability of the device and prevents overturning or tipping due to instability during lifting. The "T-shaped" lifting base can better distribute the pressure generated by the load; by distributing the pressure over a wider area, it reduces pressure concentration at a single point, thereby improving the load-bearing capacity of the lifting base. The "T-shaped" lifting base has a relatively open spatial layout, which helps to promptly identify and address potential safety hazards, ensuring the safe operation of the device.

[0046] In the above embodiments, the lifting base 3 is further slidably connected to the vertical outer wall of the translation base 2 via a longitudinal slide rail slider mechanism 9, and the longitudinal slide rail slider mechanism 9 provides linear guidance for the vertical lifting of the lifting base 3.

[0047] It should be noted that the design of the longitudinal slide rail slider mechanism 9 ensures high-precision linear motion of the lifting base 3 in the vertical direction. The high precision of the fit between the slide rail and the slider reduces deviations and swaying during movement, thus ensuring that the lifting base 3 accurately reaches the predetermined position. Because the longitudinal slide rail slider mechanism 9 provides stable linear guidance, the lifting base 3 maintains a smooth movement during lifting. This helps reduce potential damage to the device and load caused by movement impacts, improving the overall stability and service life of the device. The longitudinal slide rail slider mechanism 9 is typically made of high-strength materials and can withstand large loads. This allows the lifting base 3 to maintain a stable movement even when carrying heavy objects, preventing structural instability or damage due to excessive load. Through the connection of the longitudinal slide rail slider mechanism 9, a stable structural relationship is formed between the lifting base 3 and the translation base 2. This design helps enhance the structural stability of the entire device and prevents safety accidents caused by structural instability during lifting.

[0048] In the above embodiment, it further includes a diagonal bracing plate 17, which is a right-angled triangular structure; the diagonal bracing plate 17 is located at the turning point of the "T-shaped" lifting base 3, and the diagonal bracing plate 17 is used to prevent the lifting base 3 from deforming.

[0049] It should be noted that the right-angled triangular bracing plate 17 effectively enhances the bending resistance of the lifting base 3 at the turning points. When the lifting base 3 bears a load, the bracing plate 17 can share part of the bending moment, thereby reducing the bending deformation of the lifting base 3 itself. The bracing plate 17 is closely connected to the main structure of the lifting base 3, forming a more stable whole. This design increases the overall rigidity of the lifting base 3, making it more stable and less prone to deformation when subjected to external forces. It also disperses stress concentration, improves load-bearing capacity, reduces fatigue damage, and extends service life.

[0050] In the above embodiments, the preferred embodiment is: (in combination with) Figure 5 As shown, the lifting base 3 has a horizontal plate, and a vertically downward clamping hydraulic cylinder 7 is fixedly installed on the horizontal plate. The end of the clamping hydraulic cylinder 7 is hinged to the top power input end of a pair of inverted "V"-shaped connecting rods 12, and the bottom power output end of the pair of inverted "V"-shaped connecting rods 12 is hinged to the top of a pair of grippers 13.

[0051] It should be noted that the opening and closing degree of the gripper 13 can be precisely controlled by adjusting the extension and retraction of the clamping hydraulic cylinder 7. This design allows the clamping mechanism to adapt to loads of different sizes and shapes, improving the versatility and flexibility of the equipment. Since the top of the gripper 13 is hinged to the power output end of the connecting rod 12, the gripper 13 can adaptively adjust according to the shape and size of the load. This design helps ensure that the gripper 13 fits tightly against the load, improving the stability and reliability of the clamping.

[0052] In the above embodiments, it further includes a gripper mounting bracket 15, wherein the gripper mounting bracket 15 is hinged to the middle of the bent structure of a pair of grippers 13 via a pin 14, the top power input end of the gripper 13 is hinged to the bottom end of the connecting rod 12, and the bottom opening and closing part of the gripper 13 is used to release or clamp the irregular steel rail.

[0053] It should be noted that the gripper mounting bracket 15 is hinged to the bent structure of the gripper 13 via a pin 14. This design enhances the structural stability of the gripper 13 when clamping irregularly shaped rails. As a support structure, the gripper mounting bracket 15 can withstand the reaction force generated during clamping, preventing the gripper 13 from deforming or being damaged due to excessive force. The bottom end of the connecting rod 12 is hinged to the top power input end of the gripper 13. This connection method allows for more precise control of the opening and closing degree and clamping force when clamping irregularly shaped rails. By adjusting the length or angle of the connecting rod 12, the opening and closing degree of the gripper 13 can be finely adjusted, ensuring that the gripper 13 can closely conform to the shape and size of the irregularly shaped rail. Due to the flexible design of the bottom opening and closing part of the gripper 13, it can adapt to irregularly shaped rails of different shapes and sizes. This design gives the lifting base 3 greater versatility and flexibility when clamping irregularly shaped rails, meeting the needs of different application scenarios. The design of the gripper mounting bracket 15 and connecting rod 12 allows for flexible adjustment of the gripper 13's position. By changing the position of the pin 14 or the length of the connecting rod 12, fine-tuning of the gripper 13's clamping position can be achieved, ensuring that the gripper 13 accurately clamps the irregularly shaped rail at the designated position. Due to the hinged connection between the connecting rod 12 and the gripper 13, and the supporting role of the gripper mounting bracket 15, the gripper 13 can respond quickly and execute the clamping action when clamping the irregularly shaped rail. This design improves the equipment's operating efficiency and reduces wasted time during the clamping process. Because the clamping mechanism is rationally and efficiently designed, unnecessary energy consumption is reduced when clamping irregularly shaped rails. This helps reduce equipment operating costs and improve economic efficiency.

[0054] The working principle of this utility model is as follows: The device is arranged at the sawing station for profiled steel rails with end forming. After the end forming and sawing are completed, the steel rail continues to be conveyed forward a distance via the roller conveyor at the station until it reaches the working position of the device. At this time, the gripper 13 of this utility model is in the open state. When the steel rail reaches the working position, the clamping hydraulic cylinder 7 is activated. The piston rod of the clamping hydraulic cylinder 7 extends, driving the connecting rod 12 and the gripper 13 to rotate. The gripper 13 changes from the open state to the clamping state, clamping the rail head. Then, the lifting hydraulic cylinder 6 is activated. The piston rod of the lifting hydraulic cylinder 6 retracts, and in conjunction with the two sets of longitudinal slide rail slider mechanisms 9, the lifting base 3, which is in a low position, is raised. The lifting base 3 is raised to a position where the bottom of the profiled steel rail can avoid interference from the material rack roller conveyor. The clamping hydraulic cylinder 7, connecting rod 12, and gripper 13 are all mounted on the lifting base 3. Finally, motor 5 drives gear 11 and rack 10, which, together with two sets of transverse slide rail slider mechanisms 8, drive the translation base 2 and the components it supports and connects to, to transport the material along the horizontal longitudinal direction of the rails until the designated position. During the transport process, the forming end of the rail is in a raised state to avoid collision with the material rack roller conveyor.

[0055] As can be seen from the above description, this utility model has a simple and compact structure, and its clamping, lifting, and translation conveying are stable and reliable, making it suitable for widespread application.

[0056] This utility model of a gear transmission mechanism enables translational conveying, and features high stability and precision, high load-bearing capacity and adaptability, easy maintenance and expansion, high efficiency and energy saving, making it more reliable in the conveying of irregularly shaped steel rails.

[0057] This utility model adopts hydraulic lifting, which has the characteristics of high precision and stability, high load capacity and adaptability, high efficiency and energy saving, easy maintenance and upkeep, as well as safety and reliability.

[0059] The fixed base 1 of this utility model adopts a horizontal block structure, and a transverse slide rail slider mechanism 8 is respectively set on its top and vertical side wall.

[0061] The lifting base 3 of this utility model is designed as a horizontally placed "T-shaped" structure, which has a large support area, a lower center of gravity, improved load-bearing capacity, high structural strength, stable support, convenient spatial layout, convenient installation and maintenance, and is easy to inspect and repair.

[0062] The present invention relates to a gripper mounting bracket 15, which uses a pin 14 to hinge a pair of grippers 13 in the middle of a bent structure. The top power input end of the gripper 13 is hinged to the bottom end of an inverted "V"-shaped connecting rod. This design makes the gripping of irregularly shaped steel rails more stable and reliable. By adjusting the length or angle of the connecting rod 12, the opening and closing degree of the gripper 13 can be finely adjusted, thereby ensuring that the gripper 13 can closely fit the shape and size of the irregularly shaped steel rail. It can adapt to the gripping of irregularly shaped steel rails of different shapes, and the gripping is fast, energy-saving, efficient and safe.
