Description

Technical Field

[0001] The utility model relates to the technical field of axle fixing, in particular to a transfer sling for high-speed rail axles and an automatic transportation mechanism. Background Art

[0002] The axle of a high-speed rail train is one of the important components that support the running of the train. The high-speed rail axle usually consists of a bearing, a wheel, and a bearing seat. These components need to be precisely designed and manufactured to ensure the safe, stable, and high-speed operation of the high-speed rail train. The high-speed rail axle is usually made of special alloy steel or high-strength alloy steel to ensure sufficient strength, hardness, and wear resistance. The manufacturing of high-speed rail axles requires multiple processes, including forging, heat treatment, turning, grinding, etc., to ensure that the axles have precise dimensions and surface quality. During the processing of high-speed rail axles, the extremely heavy high-speed rail axles are usually moved by fixing them with jigs.

[0003] Chinese Patent with the publication number CN213707498U discloses a transfer sling for drilling brake drums. The technical solution disclosed in this patent document is as follows: It includes a hanging frame, the hanging frame is of an inverted U-shaped structure, both bottom ends of the hanging frame are fixedly connected with a connecting shaft, the bottom ends of both connecting shafts are rotatably connected with a hook through a rotating shaft, a push rod is fixedly connected between the two hooks, a limiting rod is elastically connected to the middle of the push rod, the limiting rod is of a U-shaped structure, and a pair of limiting holes that can match the two top ends of the limiting rod are opened on the lower surface of the hanging frame. The utility model can drive the hook to rotate by pressing the push rod, so that the hook is separated from or connected to the hanging ring, without the need to lift the brake drum hanging part upward or pull down the hook, and the operation is more convenient and labor-saving; through the design of the limiting rod and the limiting holes, it is convenient to limit the push rod and the hook, and the stability during hoisting is increased. However, the above solution still has the problem that the item to be lifted needs to be drilled. Summary of the Utility Model

[0004] One technical problem solved by the utility model is the problem that the existing device needs to drill the item to be lifted.

[0005] The technical solution adopted by the utility model is: It includes an outer ring for limiting the high-speed rail axle. The high-speed rail axle includes an axle body and a stepped surface. A clamping groove is arranged on the inner circle of the outer ring, and two inner ring parts are arranged in the clamping groove. The two inner ring parts enclose to form a limiting structure, and the stepped surface of the high-speed rail axle is clamped by the limiting structure. The inner diameter of the limiting structure is smaller than the diameter of the stepped surface, and the inner diameter of the outer ring is larger than the diameter of the stepped surface of the high-speed rail axle. Thus, the high-speed rail axle is fixed so that the high-speed rail axle will not fall off.

[0006] As a further improvement of the present utility model, fixed clamping blocks are provided on the outer sides of the joints of the outer ring. A rotating rod is slidably connected through the top of each fixed clamping block. A series connection and fixation structure is rotatably connected to the side of each fixed clamping block away from the outer ring. This enables the high-speed train axle to be evenly stressed.

[0007] As a further improvement of the present utility model, the series connection and fixation structure is used to serially fix the rotating rod, the fixed clamping block, and the outer ring, and the series connection and fixation structure is used to make the outer rings fit together. This achieves a clamping and fixing effect on the high-speed train axle.

[0008] As a further improvement of the present utility model, a rotating connection block is rotatably connected to the sides of the two rotating rods close to each other, and a fixed rod is fixedly connected to the top of the rotating connection block. This enables the high-speed train axle to be lifted.

[0009] As a further improvement of the present utility model, the length of the rotating rod is greater than the distance from the top step surface to the top of the axle body.

[0010] As a further improvement of the present utility model, the inclination angle of the inner ring part is set to 30° - 60°. The appropriate inclination angle allows the operator to more conveniently clamp the high-speed train axle.

[0011] An automatic transportation mechanism for high-speed train axles includes a number of series connection plates. The bottom of each series connection plate is fixedly connected to the top of three fixed rods. A number of transmission structures are fixedly connected to the top of each series connection plate. A transmission chain is slidably connected to the middle of the transmission structure and the series connection plate. This enables multiple high-speed train axles to be transported simultaneously.

[0012] The beneficial effects of the present utility model are as follows: 1. Through the series connection and fixation structure, the outer rings and the inner ring parts on both sides are aligned and sleeved onto the bottom of the top step surface, and then the series connection and fixation structure is contracted. As a result, the inner diameter of the inner ring part is smaller than the diameter of the step surface, and the inner diameter of the inner ring part is larger than the diameter of the axle body. This achieves the fixation of the high-speed train axle. Compared with the existing lifting tools that require drilling, this method does not damage the high-speed train axle by drilling. It reduces the damage to the axle structure and extends its service life. It also reduces the cost and time of maintenance and repair because no additional drilling process is required. Avoiding damage to the axle structure improves the operation safety and reduces accidental risks.

[0013] Through the transmission chain, the transmission structure and the series plate, the movement of the transmission chain will drive the middle part of the transmission structure to rotate, so as to transfer the high-speed rail axle under the action of friction. The automatic transfer can accelerate the material flow speed in the axle processing process, reduce the waiting time, and thus improve the overall production efficiency. Moreover, the automatic transfer can reduce the demand for manual operation, lower the labor cost and labor intensity, and at the same time reduce the impact of human factors on product quality. The automatic transfer system can also accurately control the position and direction of the axle, reduce the errors that may be caused by manual operation, and is conducive to improving the processing accuracy and product quality. Moreover, the automatic transfer can realize the continuous operation of the production line, avoid the shutdown and production interruption caused by the discontinuity of manual operation, and is conducive to improving the continuity and stability of the overall production line.

Detailed Embodiment

[0017] The following will further describe the present utility model with reference to the drawings.

[0018] As shown in the figure, a transfer sling and an automatic transportation mechanism for a high-speed rail axle include an axle body 101, a step surface 102, a series fixing structure 205, an outer ring 206 and an inner ring part 207.

[0019] When it is necessary to transfer the high-speed rail axle 100, the two outer ring parts 206 and the inner ring part 207 are attached to the bottom position of the top step surface 102, and then the two outer ring parts 206 and the inner ring part 207 are attached to each other through the series fixing structure 205. When the outer ring part 206 and the inner ring part 207 are completely attached, the inner diameter of the inner ring part 207 is smaller than the diameter of the step surface 102, and the inner diameter of the inner ring part 207 is larger than the diameter of the axle body 101. Thus, the high-speed rail axle 100 is fixed, achieving the effect that, compared with the existing lifting tools that require drilling, there is no need to drill and damage the high-speed rail axle 100. Not drilling the high-speed rail axle 100 can reduce the damage to the axle structure and extend its service life. Moreover, it can also reduce the costs and time for maintenance and repair because no additional process for drilling is required.

[0020] Furthermore, since the rotating rods 203 are slidably connected inside the fixing blocks 204 fixed on both sides of the outer ring part 206 and the inner ring part 207, and the top of the rotating connection block 202 rotatably connected to the rotating rod 203 is fixedly connected to the fixing rod 201, when the fixing rod 201 moves driven by the series plate 303, the high-speed rail axle 100 will be lifted. Automated lifting can realize the continuous operation of the production line, avoiding work stoppages and production interruptions caused by discontinuous manual operations, which is beneficial to improving the continuity and stability of the overall production line. Moreover, the automated lifting system can precisely control the position of the axle and the lifting process, reducing the errors that may be caused by manual operations, which is beneficial to improving the operation accuracy and product quality.

[0021] Furthermore, after the axle is lifted, by starting the transmission chain 301, the middle part of the transmission structure 302 will be driven to rotate by friction under the movement of the transmission chain 301. Thus, the effect of making the transmission structure 302 move along with the operation of the transmission chain 301 is achieved. Since the series plate 303 fixedly connected to the bottom end of the transmission structure 302 has a fixing rod 201 fixedly connected to its bottom end, the movement of the transmission structure 302 will drive the high-speed rail axle 100 to move horizontally automatically. Thus, the effect of automatically transferring the high-speed rail axle 100 can be achieved. Automated transfer can accelerate the material flow speed during the axle processing, reduce the waiting time, and thus improve the overall production efficiency. Moreover, automated transfer can reduce the need for manual operations, lower the labor cost and labor intensity, and at the same time reduce the impact of human factors on product quality.

[0022] The advantages of the present utility model are as follows: 1) Drilling is not required for high-speed rail axles, which can reduce damage to the axle structure and extend its service life. 2) Automatic lifting can achieve continuous operation of the production line, avoiding shutdowns and production interruptions caused by discontinuous manual operations, and is conducive to improving the continuity and stability of the overall production line. 3) Automatic transfer of high-speed rail axles can accelerate the material flow rate during the axle processing, reduce waiting time, and thus improve the overall production efficiency. 4) Avoiding drilling can prevent damage to the axle structure, improve operation safety, and reduce accidental risks. 5) Automatic transfer can achieve continuous operation of the production line, avoiding shutdowns and production interruptions caused by discontinuous manual operations, and is conducive to improving the continuity and stability of the overall production line.
