Description

Technical Field

[0001] This utility model belongs to the field of rail production technology, specifically, it relates to a guide wheel device for the bottom of a rail production roller conveyor. Background Technology

[0002] The guide wheel device at the bottom of the rail production roller conveyor is a mechanical device used to guide and position the rails as they move on the roller conveyor. Its core function is to achieve precise guidance of the rails through rolling friction, ensuring the stability and efficiency of the production process.

[0003] The prior art discloses a rail roller conveyor guiding mechanism (CN206705182U), which includes a roller conveyor, at least a pair of guide rollers are provided on the roller conveyor, and a boss is provided at the end of the guide roller away from the roller conveyor. The working surface of the guide roller and the roller conveyor together form a rail channel with an open top. The rail is placed upside down in the rail channel, the upper tread surface of the rail is located on the roller conveyor, and the rail web is located between the bosses. The rail bottom and rail legs do not have direct contact with the transport components, and the rail bottom coating is effectively protected to ensure the coating quality of the rail.

[0004] Research revealed that existing technologies, when lifting rails onto the roller conveyor, are prone to causing the rails to fall directly onto the guide rollers due to positional deviations. This leads to problems such as jamming, wear, and difficulty in rail movement. This not only reduces production efficiency but also increases maintenance costs. Furthermore, the guide rollers in existing technologies are mostly welded and fixed, lacking adjustability and unable to adapt to changes in rail width. They also lack a buffer mechanism, making it easy for the falling rails to damage the device.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A guide wheel device for the bottom rail of a steel rail production roller line includes a steel rail, a support, and a driven roller. Two supports are symmetrically arranged, and the same driven roller is rotatably connected between the two supports. The steel rail is slidably fitted on the driven roller.

[0008] The guide assembly includes a guide assembly at each end of the passive roller. The guide assembly includes a base, a conical guide baffle, and a guide wheel. The base is fixedly installed on the roller conveyor by bolts. The guide wheel is rotatably mounted on the base. The conical guide baffle is welded and fixed to the top surface of the guide wheel.

[0009] An elastic adaptation mechanism is movably disposed within a guide wheel. The elastic adaptation mechanism includes an adaptation abutment, a feeding wheel, a square plate, and a connecting rod. The adaptation abutment is movably disposed at the four internal corners of the guide wheel. The feeding wheel and the square plate are rotatably disposed within the guide wheel. The connecting rod is hinged between the square plate and the adaptation abutment. The square plate is movably disposed on the top surface of the feeding wheel.

[0010] In a preferred embodiment of this utility model, a bearing support is fixedly connected to the top surface of the base, and the guide wheel is rotatably connected to the bearing support.

[0011] In a preferred embodiment of this utility model, the conical guide baffle is provided with a slot, and multiple sets of conveying wheels are arranged in an array inside the slot. The conveying wheels are rotatably connected inside the slot, and the curved surface of the conveying wheels is flush with the curved surface of the slot.

[0012] In a preferred embodiment of this utility model, the guide wheel has an inner cavity, and the four corners of the outer curved surface of the guide wheel each have an arc-shaped shrinkage groove, which communicates with the inner cavity. The adapting abutment rod slides through and between the shrinkage groove and the inner cavity.

[0013] In a preferred embodiment of this utility model, a pulley is rotatably provided at one end of the adapting abutment rod that extends into the inner cavity. The pulley slides and engages with the curved surface of the abutment wheel. A connecting rod is hinged to each of the four corners of the square plate, and an adapting abutment rod is hinged to each of the four corner connecting rods.

[0014] In a preferred embodiment of this utility model, a turntable is rotatably arranged inside the inner cavity, and a cross-shaped abutting wheel is fixedly connected to the top surface of the turntable. The square plate is rotatably arranged on the top surface of the abutting wheel.

[0015] In a preferred embodiment of this utility model, a spring is fixedly provided between the inner center of the feeding wheel and the bottom surface of the square plate, and the feeding wheel is elastically connected to the square plate through the spring.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By setting up a guide assembly, conveyor wheels are arrayed in the groove of the conical guide baffle, which converts sliding friction into rolling friction. When the rail is lifted by a hoist and placed on the roller conveyor, after the rail contacts the inclined surface of the conical guide baffle, it moves down onto the roller conveyor under the rolling cooperation of multiple sets of conveyor wheels, completing the normal movement of the rail. This avoids the rail from getting stuck and has difficulty moving, while reducing wear on the rail.

[0018] 2. By setting up an elastic adaptation mechanism and the linkage design of the spring and connecting rod, the adaptive abutment rod can adaptively drive the connecting rod and the abutment wheel according to the change of the rail bottom width. The connecting rod drives the square plate, avoiding the jamming problem caused by the change of rail shape of the traditional fixed guide wheel. In addition, the elastic energy stored in the spring can convert the impact energy of the falling rail into mechanical deformation energy, thereby reducing the impact load and reducing some of the impact force damage to the equipment.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A guide wheel device for the bottom of a rail production roller conveyor, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a rail 10, a support 12 and a driven roller 13. Two supports 12 are symmetrically arranged, and the two supports 12 are rotatably connected to the same driven roller 13. The rail 10 is slidably fitted on the driven roller 13.

[0029] The guide assembly has a guide assembly at each end of the passive roller 13. The two guide assemblies form a V-shaped guide channel for conveying the rail 10 through their respective conical guide baffles 14. The guide assembly includes a base 11, a conical guide baffle 14 and a guide wheel 15. The base 11 is fixedly installed on the roller table by bolts. The guide wheel 15 is rotatably mounted on the base 11. The conical guide baffle 14 is welded and fixed to the top surface of the guide wheel 15.

[0030] The elastic adaptation mechanism is movably disposed within the guide wheel 15. The elastic adaptation mechanism includes an adaptation rod 17, a feeding wheel 22, a square plate 25, and a connecting rod 26. The adaptation rod 17 is movably disposed at the four internal corners of the guide wheel 15. The feeding wheel 22 and the square plate 25 are both rotatably disposed within the guide wheel 15. The connecting rod 26 is hinged between the square plate 25 and the adaptation rod 17. The square plate 25 is movably disposed on the top surface of the feeding wheel 22.

[0031] Specifically, this device utilizes a V-shaped guide channel formed by guide components on both sides to guide and transport the rail 10, and uses guide wheels 15 within the guide components on both sides to guide and correct the rail 10. Then, the rotation of the passive roller 13 assists in the transport of the rail 10. In this device, by setting up guide components and using an array of conveyor wheels 19 within a conical guide baffle 14, sliding friction is converted into rolling friction. When the rail is lifted by a hoist and placed on the roller conveyor, after the rail 10 contacts the inclined surface of the conical guide baffle 14, it moves downwards onto the roller conveyor under the rolling cooperation of multiple sets of conveyor wheels 19, completing the normal movement of the rail 10. This avoids descent jamming and difficulty in rail movement while reducing wear on the rail. Then, the falling rail 10 pushes against the elastic adaptation mechanism, allowing the adapting abutment rod 17 to adaptively drive the connecting rod 26 and the abutment wheel 22 according to the change in the width of the rail bottom of the rail 10. The connecting rod 26 drives the square plate 25, avoiding the jamming problem caused by changes in the rail shape of traditional fixed guide wheels.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a bearing support 16 is fixedly connected to the top surface of the base 11. A bearing hole is provided in the bearing support 16. A shaft is integrally formed on the bottom surface of the guide wheel 15. The shaft of the guide wheel 15 is rotatably connected to the bearing hole in the bearing support 16 through a bearing.

[0033] like Figure 3 As shown, a slot 20 is provided on the conical guide baffle 14. Multiple sets of conveyor wheels 19 are arranged in an array inside the slot 20 to reduce friction. The conveyor wheels 19 are rotatably connected to the slot 20 through bearings, and the curved surface of the conveyor wheels 19 is flush with the curved surface of the slot 20.

[0034] The working principle is as follows: when the rail 10 is lifted by the hoist and placed on the roller conveyor, after the rail 10 contacts the inclined surface of the conical guide baffle 14, it is assisted by the conveyor wheel 19 in the groove 20 of the conical guide baffle 14 to accelerate the process of the rail 10 falling. This converts the sliding friction between the rail 10 and the curved surface of the conical guide baffle 14 into rolling friction, reduces frictional resistance, and helps the rail 10 move smoothly to the roller conveyor. At this time, the movement of the rail 10 after falling directly drives the passive roller 13 to rotate, completing the normal movement of the rail.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, the guide wheel 15 has an inner cavity 27 inside. The inner cavity 27 is a cross-shaped cavity composed of a cylindrical cavity and four slides. An arc-shaped contraction groove 18 is opened at each of the four corners of the outer curved surface of the guide wheel 15. The contraction groove 18 communicates with the inner cavity 27. The adapting abutment rod 17 slides through and between the contraction groove 18 and the inner cavity 27. The adapting abutment rod 17 is composed of an arc-shaped plate corresponding to the contraction groove 18 and a square rod. The arc-shaped plate slides through and within the slide through the square rod.

[0036] like Figure 4 As shown, a pulley 24 is rotatably provided at one end of the adapting abutment 17 that extends into the inner cavity 27. The pulley 24 slides in cooperation with the curved surface of the abutment wheel 22. A connecting rod 26 is hinged between the top surface of the end of the adapting abutment 17 that extends into the inner cavity 27 and one corner of the square plate 25. The abutment 26 is L-shaped. A connecting rod 26 is hinged at each of the four corners of the square plate 25. The square plate 25 is hinged to an adapting abutment 17 through the connecting rods 26 at the four corners.

[0037] like Figure 4 and Figure 5 As shown, a turntable 21 is rotatably mounted inside the inner cavity 27. A cross-shaped abutment wheel 22 is fixedly connected to the top surface of the turntable 21. The turntable 21 is configured to correspond to the specifications of the cylindrical cavity. A connecting shaft is provided on the bottom surface of the square plate 25, and the square plate 25 is rotatably mounted on the top surface of the abutment wheel 22 via the connecting shaft; Figure 5 As shown, a spring-loaded spring 23 is fixedly installed between the inner center of the feed wheel 22 and the bottom surface of the square plate 25, and the feed wheel 22 is elastically connected to the square plate 25 through the spring-loaded spring 23.

[0038] Specifically, in the initial state, the spring 23 is in a relatively static, non-energy-storing state. At this time, the adapting abutment 17 is exposed outside the contraction groove 18. At this time, the outer curved surface of the abutment wheel 22 touches the pulley 24, and the four sides of the square plate 25 are perpendicular to the slide rail. When the rail 10 falls, the bottom of the rail 10 presses against the adapting abutment 17 in the guide components on both sides. Under the action of compression, the adapting abutment 17 on both sides adapts to the width of the bottom of the rail 10 and pushes the connecting rod 26 to move. The connecting rod 26 is driven by force to rotate the square plate 25 and the abutment wheel 22. Here, the square plate 25 and the abutment wheel 22 move in opposite directions. Since the shape of the abutment wheel 22 is similar to a one-way windmill structure, when the pulley 24 moves towards the center of the inner cavity 27, the abutment wheel 22 can only rotate clockwise in one direction when it is pushed. And since the shape of the connecting rod 26 is similar to a one-way windmill structure, the abutment wheel 22 can only rotate clockwise in one direction when it is pushed. The L-shaped rod has its opening facing clockwise. When the pulley 24 approaches the center of the inner cavity 27, it pushes the connecting rod 26 to rotate counterclockwise. The connecting rod 26, in conjunction with the four corner adaptive abutment rods 17, adjusts synchronously to form an adaptive guiding force. Therefore, at this time, the spring 23 is subjected to a preload generated in opposite directions between the square plate 25 and the abutment wheel 22. At this time, the adaptive abutment rods 17 on both sides simultaneously clamp the bottom of the rail 10. The guide wheel 15 and the driven roller 13 guide the movement of the rail 10. During the process, the adaptive abutment rods 17, in conjunction with the rotation of the guide wheel 15, adhere to the surface of the bottom of the rail 10 for rotational conveying. When the rail 10 is disengaged, the spring 23 releases its stored energy, driving the square plate 25 and the abutment wheel 22 to rotate in opposite directions, thereby realizing the reset process.
