Description

Technical Field

[0001] This utility model relates to the field of railway sleeper production and conveying technology, and in particular to a railway sleeper conveying line. Background Technology

[0002] In railway construction and maintenance, railway sleepers are crucial railway components, and their production and transportation are of paramount importance. Traditional sleeper conveying equipment suffers from numerous problems in practical applications, such as sleeper slippage and misalignment during transport, leading to low conveying efficiency; poor adaptability to different sleeper sizes, failing to meet diverse production needs; and the lack of an effective centering adjustment mechanism, affecting the subsequent stacking and usage accuracy of sleepers. Therefore, developing a new type of sleeper conveying line that can solve these problems is of significant practical importance. Utility Model Content

[0003] The main purpose of this utility model is to provide a sleeper conveyor line that can effectively solve the problems of sleeper slippage and deviation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A sleeper conveyor line includes a linear support frame one and a linear support frame two. Both the linear support frame one and the linear support frame two are provided with multiple horizontal rollers inside. The end of the linear support frame one away from the linear support frame two is also provided with an arc-shaped support component. The side of the linear support frame two along the flow line direction is also provided with a centering component.

[0006] Preferably, the arc-shaped support assembly includes a connecting frame, with arc-shaped brackets at both ends of the connecting frame. The central axes of the two arc-shaped brackets coincide, and an inclined roller is rotatably mounted between the two arc-shaped brackets. The outer surface of the inclined roller is covered with a rubber pad, and the outer surface of the rubber pad has a plurality of friction strips arranged in a ring.

[0007] Preferably, the inclined roller surface is provided with multiple steps symmetrically arranged on the left and right sides, and adjacent steps are transitioned by inclined edges.

[0008] Preferably, the inclined roller is inclined downward on the side away from the central axis of the arc-shaped support.

[0009] Preferably, the centering component includes a double-ended bolt that rotates between the linear support frames. A nut is threaded onto the outer surface of the double-ended bolt. A guide plate is rotatably mounted on the upper end of the nut. The two side walls of the linear support frame are also provided with mounting grooves. Limiting grooves are provided on the bottom and top surfaces of the mounting grooves. The guide plate is slidably mounted in the limiting grooves.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This sleeper conveyor line adopts an arc-shaped support component design. The inclined roller is covered with a rubber pad and equipped with friction strips, which increases the friction between the roller and the sleeper and effectively prevents the sleeper from slipping during transmission. At the same time, the inclined design of the inclined roller and the staggered step structure make the inner ring conveying speed of the sleeper slower than the outer ring when turning, accurately controlling the turning of the sleeper, avoiding positional deviation, and ensuring a stable and accurate conveying process.

[0012] 2. This sleeper conveyor line adopts a centering component design. By adjusting the double-headed bolts and nuts, the spacing of the guide plates can be flexibly changed to achieve centering and straightening of the sleepers, which facilitates subsequent stacking and use, and improves the practicality and convenience of sleeper conveying.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 - Figure 4 As shown, a sleeper conveying line includes a linear support frame 1 and a linear support frame 2. Both the linear support frame 1 and the linear support frame 2 are equipped with multiple horizontal rollers 3. The horizontal rollers 3, the linear support frame 1, and the linear support frame 2 are all existing technologies. The horizontal rollers 3 are used for conveying the sleepers. The end of the linear support frame 1 away from the linear support frame 2 is also equipped with an arc-shaped support component 4. The linear support frame 2 is also equipped with a centering component 5 on one side along the flow line direction.

[0020] like Figure 2 and Figure 3As shown, the arc-shaped support assembly 4 includes a connecting frame 41, with arc-shaped brackets 42 at both ends of the connecting frame 41. The central axes of the two arc-shaped brackets 42 coincide, and the two arc-shaped brackets 42 are used to support the inclined roller 43. The inclined roller 43 is rotatably mounted between the two arc-shaped brackets 42 so that the device can change the conveying direction when conveying the sleeper. In addition, the rotation and control methods of the horizontal roller 3 and the inclined roller 43 are existing technologies, and will not be described in detail in this embodiment. The outer surface of the inclined roller 43 is covered with a rubber pad, and multiple friction strips 44 are arranged in a ring on the outer surface of the rubber pad. The friction strips 44 are made of a soft, elastic material, such as rubber, to facilitate the production and molding of the friction strips 44. The integrated design can also prevent the friction strips 44 from tilting or falling off during the sleeper conveying process, thereby affecting the normal operation of the device. The friction strips 44 can increase the friction between the inclined roller 43 and the sleeper, preventing the sleeper from slipping during the conveying process of the inclined roller 43.

[0021] In addition, since the device may need to transport the sleepers in different directions during actual use, the design of multiple arc-shaped support components 4 can adjust the transport direction of the sleepers by setting the number of arc-shaped support components 4 so that the device can be used to adapt to different working conditions.

[0022] like Figure 3 As shown, the inclined roller 43 has multiple steps symmetrically arranged on its surface. Adjacent steps are connected by an inclined edge. The stepped design of the inclined roller 43 prevents the sleeper from shifting during transport, thus affecting the normal operation of the device. Multiple sets of steps also make it suitable for sleepers of different sizes. Furthermore, the side of the inclined roller 43 away from the central axis of the arc-shaped support 42 is inclined downwards. Since the inner conveying speed is slower than the outer conveying speed when the sleeper turns during transport, the inclined roller 43 needs to be tilted. Because the inclined roller 43 has multiple symmetrical steps on its surface, the sleeper presses against the steps during transport. The staggered steps of the inclined roller 43 support the sleeper. The different diameters of the staggered steps ensure that the inner conveying speed is slower than the outer conveying speed when the sleeper turns, preventing the sleeper from shifting during transport and affecting its normal transport.

[0023] like Figure 4As shown, the centering component 5 includes a double-ended bolt 51 that rotates between the linear support frames. A nut 52 is threaded onto the outer surface of the double-ended bolt 51. Due to the design of the double-ended bolt 51 and nut 52, when a mechanism limits the nut 52 (i.e., the nut 52 cannot rotate with the double-ended bolt 51), the rotation of the double-ended bolt 51 allows the two nuts 52 to move away from each other. A guide plate 53 is rotatably mounted on the upper end of the nut 52. The side wall of the linear support frame 2 also has a mounting groove 54. The bottom surface of the inner cavity of the mounting groove 54... Both the top and bottom surfaces have limit grooves 55, and the guide plate 53 is slidably installed in the limit groove 55. Due to the design of the guide plate 53 sliding in the limit groove 55 and the rotatable connection between the guide plate 53 and the nut 52, it can prevent the nut 52 from rotating with the double-ended bolt 51 when the double-ended bolt 51 rotates. When the double-ended bolt 51 rotates, the two nuts 52 move to the side closer to each other or to the side farther away from each other, thereby adjusting the shortest distance between the two guide plates 53, so that the sleeper to be used is centered and straightened, so as to facilitate the stacking and use of the device.

[0024] The method of using the device is as follows: During installation, first fix and level the linear support frame 1 and linear support frame 2 according to the layout, install multiple horizontal rollers 3 inside them, install inclined rollers 43 to make them rotate smoothly, and check whether there is any abnormality in the rotation of the rollers.

[0025] After normal debugging, the sleepers are transported. The sleepers are placed on the horizontal roller 3 and transported in a straight line. When they reach the turning point, the rubber pads and friction strips 44 of the inclined roller 43 increase the friction to prevent the sleepers from slipping. At the same time, the inclined design of the inclined roller 43, combined with the staggered steps, allows the sleepers to turn during transport.

[0026] Since the sleeper will tilt when turning, the double-ended bolt 51 is adjusted according to the width of the sleeper. When the double-ended bolt 51 rotates, it adjusts the shortest distance between the guide plates 53 through the cooperation between the double-ended bolt 51 and the nut 52, so as to guide the sleeper back to the correct position.

[0027] The installation of components, circuit connections, and control methods of this utility model are conventional designs. During use, operators need to regularly inspect and maintain the equipment to ensure good operating condition and improve the efficiency and quality of sleeper transportation.

[0028] It should be noted that the specific installation methods and control methods of the double-headed bolt 51 and nut 52 in this utility model are all conventional designs, and will not be described in detail in this utility model.
