Detailed Implementation

[0029] The following will refer to the appendix in the embodiments of this utility model. Figures 2-9 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.

[0030] (like Figure 3 (As shown) A floating guide rail device for feeding steel rails includes a roller bracket 1, which is horizontally arranged, and several rollers 3 are mounted side by side on the top of the horizontal frame of the roller bracket 1 via several pins 2. It has high load-bearing capacity, low frictional resistance, stable operation, and is easy to maintain.

[0031] In the above embodiments, preferably, the rollers 3 are horizontally and tightly and orderly fixed above the roller bracket 1 by means of pins 2, forming a horizontal and stable rolling support surface.

[0032] This makes the entire device more stable when carrying the rails, reducing swaying and vibration caused by uneven gaps or misalignments between the rollers 3. By horizontally and closely aligning the rollers 3, the weight and pressure from the rails can be more effectively distributed and borne, thereby improving the overall load-bearing capacity of the device. This is particularly important for handling heavy rail materials, ensuring the stability and safety of feeding. The close arrangement of the rollers 3 also reduces relative movement between the rollers, thus reducing wear and friction loss. Furthermore, since the rollers 3 can be individually disassembled and replaced, this design also reduces maintenance costs and time.

[0033] (like Figure 7 In the above embodiment (as shown), preferably, the roller bracket 1 is composed of a square box 101, a channel steel 102, and ear plates 103. The square box 101 is horizontally arranged, and the top of the square box 101 is horizontally supported by the channel steel 102 with its opening facing upward. The channel steel 102 is equipped with several rollers 3 side by side through several pins 2. The front and rear ear plates 103 are respectively fixedly installed on the front and rear vertical outer walls at both ends of the square box 101, and the ear plate connecting holes of the front and rear ear plates 103 are coaxially arranged.

[0034] The square box 101 is the base component of the roller support, and its horizontal arrangement ensures the stability of the entire support. The design of the square box 101 shape makes the support have better anti-deformation ability when bearing heavy load. The channel steel 102 is installed at the top of the square box 101, and its upward opening design facilitates the installation and maintenance of the rollers 3. The channel steel 102, as a carbon structural steel, has good mechanical properties and load-bearing capacity, further enhancing the structural stability of the roller support. The channel steel 102 is installed with several rollers 3 side by side through several pin shafts 2, and this design ensures the close arrangement and stable support of the rollers in the horizontal direction. The pin shaft 2, as the mounting shaft of the roller, has a reasonable number and position design, ensuring the stable installation and smooth rolling of the roller on the channel steel. The front and rear vertical outer walls at the left and right ends of the square box 101 are fixedly installed with front and rear ear plates 103, respectively. This design allows the roller support to be easily connected and fixed with other components. The ear plate connection holes of the front and rear ear plates 103 are coaxially arranged, ensuring that the connecting piece can be smoothly inserted and tightened, improving the reliability and stability of the connection. The entire roller support 1 design considers the convenience of installation and maintenance. The connection between the square box 101, channel steel 102, and ear plate 103 is simple and clear, facilitating disassembly and reinstallation.

[0035] The left and right ends of the roller support 1 are respectively connected to the top end of the piston rod of the hydraulic oil cylinder 5 through the cross joint 4. The piston rod of the hydraulic oil cylinder 5 is vertically lifted, and the roller support 1 is driven to vertically lift through the vertically lifted piston rod.

[0036] The piston rod of the hydraulic oil cylinder 5 can be vertically lifted, which means that the height of the roller support 1 can be flexibly adjusted, making the entire steel rail feeding floating guide rail device adapt to the steel rail feeding requirements of different heights, improving the versatility and flexibility of the equipment. The roller support 1 is connected to the top end of the piston rod of the hydraulic oil cylinder 5 through the cross joint 4, ensuring the stability of the roller support during vertical lifting, avoiding tilting and shaking, and ensuring stable support and load-bearing. The hydraulic oil cylinder 5 is usually equipped with a precise control system, which can realize the precise lifting of the piston rod, which means that the height of the roller support 1 can be accurately adjusted to the required position, meeting the high-precision feeding requirements. In some complex feeding conditions, such as large changes in the height of the steel rail or the need to frequently adjust the feeding height, this design can quickly respond to and adapt to these changes. The connection between the hydraulic oil cylinder 5 and the roller support 1 makes the maintenance and maintenance of the equipment easier, and the relevant components can be easily disassembled and reinstalled. The roller support 1 is driven to vertically lift through the vertically lifted piston rod, which can quickly adjust the feeding height, thereby improving the feeding efficiency.

[0037] (As Figure 8 , Figure 9In the above embodiments, preferably: the cross joint 4 is composed of a pin shaft 401 and a pin shaft sleeve 402; the pin shaft 401 is sleeved with the pin shaft sleeve 402, and the pin shaft sleeve 402 and the pin shaft 401 form a cross intersection structure; the bottom of the pin shaft sleeve 402 is connected to the top end of the piston rod of the hydraulic cylinder 5 through a thread 4021; and the pin shaft 401 is supported at both ends by the front and rear ear plates 103 of the roller bracket 1.

[0038] The cross intersection structure of the pin shaft 401 and the pin shaft sleeve 402 provides a stable connection point, ensuring that the roller bracket 1 can remain stable during vertical lifting and prevent shaking or tilting. The thread 4021 connecting the bottom of the pin shaft sleeve 402 to the top end of the piston rod of the hydraulic cylinder 5 is not only firm and reliable, but also easy to disassemble and reassemble, increasing the flexibility of the connection. The design of the cross joint 4 allows the roller bracket 1 to be precisely positioned at the top end of the piston rod of the hydraulic cylinder 5, ensuring the accuracy and consistency of the lifting action. The combination of the pin shaft 401 and the pin shaft sleeve 402 can withstand a large load, meeting the strength and stability requirements of the roller bracket 1 during vertical lifting and ensuring the normal operation of the equipment. The structure of the cross joint 4 is relatively simple, easy to disassemble and inspect, and if necessary, the relevant parts can be quickly replaced or repaired, reducing maintenance costs and time. The cross joint 4 can reduce friction and wear between the roller bracket 1 and the piston rod of the hydraulic cylinder 5, thereby prolonging the service life of the equipment.

[0039] In the above embodiments, further: the pin shaft 401 is supported at both ends by the front and rear ear plates 103 of the roller bracket 1, and the pin shaft 401 is coaxially connected to the ear plate connection holes of the front and rear ear plates 103.

[0040] The coaxial connection of the pin shaft 401 to the front and rear ear plates 103 increases the overall stability of the roller bracket 1. Since the pin shaft 401 is coaxially connected to the ear plate connection holes of the front and rear ear plates 103, the accuracy and stability of the connection are ensured, preventing the roller bracket 1 from shifting or deforming under stress. The pin shaft 401, as a support component, is designed to withstand the weight and pressure from the roller bracket 1 and the rollers thereon. The coaxial connection to the front and rear ear plates 103 further enhances this load-bearing capacity, allowing the roller bracket 1 to stably support the rail and perform feeding operations. The coaxial connection design reduces the risk of gaps and looseness at the connection site, improving the reliability of the connection and ensuring that the roller bracket 1 can maintain a stable connection state during lifting and feeding, preventing faults or accidents caused by loose connections. The coaxial connection design of the pin shaft 401 to the front and rear ear plates simplifies the installation process and helps maintain the geometric accuracy of the roller bracket 1.

[0041] The upper limiting device 6 and the lower limiting device 7 are installed on the vertical side of the roller support 1 frame body. Specifically, the upper limiting device 6 and the lower limiting device 7 are connected to the input end of the controller, and the output end of the controller is connected to the control input end of the hydraulic cylinder 5. In the above embodiment, further: the upper limiting device 6 and the lower limiting device 7 are both photoelectric sensors, the upper limiting device 6 is used to control the floating rail to stop lifting, and the lower limiting device 7 is used to control the floating rail to return to the starting zero position.

[0042] Wherein, the upper limiting device 6 and the lower limiting device 7 can accurately detect the lifting position of the roller support 1, when the roller support reaches the preset upper or lower limit position, the corresponding limiting device will trigger the controller, so as to stop or reverse the action of the hydraulic cylinder 5, realizing accurate control. By setting the upper limiting device 6 and the lower limiting device 7, it can prevent the equipment damage or personnel injury caused by excessive lifting of the roller support 1, and improve the safety of the whole rail feeding floating rail device. The connection of the limiting device and the controller realizes automatic control, when the roller support 1 lifts to the preset position, it can automatically stop or reverse without manual intervention, improving the automation degree and work efficiency of the equipment. The upper limiting device 6 and the lower limiting device 7 are both photoelectric sensors, which have the advantages of fast response speed and high detection accuracy. At the same time, they are easy to install and maintain, reducing the maintenance cost and time of the equipment. The photoelectric sensor can adapt to different working environments and light conditions, ensuring accurate detection of the position of the roller support 1 in different situations, so that the whole device has stronger adaptability and flexibility. In addition to the basic limiting function, the photoelectric sensor can also be used as a fault warning device, when the roller support 1 lifts abnormally or the sensor cannot detect the signal, the controller can issue an alarm or stop the equipment running, so as to avoid potential safety hazards. By accurately controlling the lifting position of the roller support 1, it can avoid the equipment wear and damage caused by excessive lifting, prolong the service life of the equipment, and reduce the replacement and maintenance cost.

[0043] It should be noted that the utility model also includes a hydraulic station and an electrical control system. The utility model is evenly distributed in the feeding system, and the layout and quantity are reasonably designed according to the actual transportation bearing demand and site conditions. When in use, the hydraulic station is started to provide power source for the hydraulic cylinder 5, so that it has the action ability, then the lifting and falling actions of the hydraulic cylinder 5 are accurately controlled through the electrical control system to realize the lifting function of the floating rail. The operator only needs to operate simply on the operation panel of the electrical control system according to the set operation process to complete the rail piece 8 conveying task. In the whole process, the parts act cooperatively to ensure that the rail piece is conveyed to the specified position stably and accurately, and the operation safety and reliability are ensured.

[0044] The working principle of the utility model is as follows: (as Figure 2Before the steel rail 8 is fed, the power supply, the hydraulic station and the electrical control system are started, the roller support 1 is first lifted by the hydraulic cylinder 5 to lift the steel rail 8 to a height higher than the highest point of the feeding storage rack 9 and the roller 11, and then the rail 8 is pulled to the roller 11 by the pulling mechanism 10 to avoid transverse scratches on the rail bottom and ensure stable transportation; after the feeding is completed, the roller support 1 is reset to the starting zero position by the hydraulic cylinder 5.

[0045] It can be found from the above description that the roller 3 as a component directly contacting the steel rail is arranged in a dense manner and bears the functions of supporting and rolling, thereby greatly increasing the contact points between the rail 8 and the roller 3, reducing the friction between the rail 8 and the roller support 1, effectively preventing scratches between the rail 8 and the roller support 1, and enabling the rail to smoothly move on the roller support 1.

[0046] The pin shaft 2 is used for fixing the rollers 3 on the roller support 1 to ensure the stability and position accuracy of the rollers 3 during operation and prevent the rollers 3 from deviating or falling off.

[0047] The roller support 1 as a mounting base of the rollers 3 bears the rollers 3 and transmits force, has stable, safe and reliable structural strength, realizes lightweight design, and ensures that the roller support 1 does not deform or be damaged under the action of the weight of the rail and various forces in the transportation process.

[0048] The cross joint 4 is threadedly connected with the piston rod of the hydraulic cylinder 5 in the vertical direction, the horizontal end of the other end of the cross joint 4 is connected with the ear plate connection hole reserved in the horizontal direction of the roller support 1, the split structure of the cross joint 4 facilitates on-site disassembly and installation, the structure is simple, the connection is reliable, and the stress is stable.

[0050] The upper limiting device 6 and the lower limiting device 7 control whether the floating guide rail is in place, the floating guide rail stops lifting when reaching the upper limit, and the floating guide rail returns to the original position when reaching the lower limit, and this mode can realize stable feeding in the actual feeding process.

[0051] According to the utility model, the floating guide rail device is added, the rail piece 8 is lifted to the height exceeding the highest point of the feeding storage rack 9 and the roller way 11 before drawing, then the rail piece 8 is drawn to the roller way 11 through the drawing mechanism 10, the scratch on the rail bottom is avoided, the technical problem that the rail bottom horizontal scratch is prone to occur on the contact surface of the traditional transport rail piece and the transportation is not stable is solved, the simple structure is easy to operate, easy to realize, practical, strong adaptability, safe, stable and reliable.
