Description

Technical Field

[0001] The invention relates to the technical field of sleeper rail production, and in particular to a sleeper rail production line. Background Art

[0002] Sleepers (or sleepers, sleeper plates) are key components of railway track systems. They support the rails, maintain the geometry of the track, disperse the load of the train, and maintain the stability of the track. With the development of railway transportation, the performance and life requirements of sleepers have been continuously improved, prompting the transition from wooden sleepers to concrete sleepers. In the production process of concrete sleepers, "secondary casting" or "post-casting" technology is sometimes used, that is, it is first made into a hollow and then concrete is poured into it. This casting method is for prestressing. In the production of prestressed concrete sleepers, holes are reserved first to install prestressed steel bars or steel wires inside the sleepers and tension them. Prestressing is applied by stretching and fixing the steel bars before the concrete hardens, and then pouring concrete around the steel bars. The reserved holes are to facilitate the installation and tensioning of prestressed steel bars and ensure that the prestress can be evenly distributed. The existing technology can realize the production line production of sleepers with a high level of automation, but the efficiency of finishing after secondary casting is low, and the smoothing effect is not ideal.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] Reference Figure 1 to Figure 7 An embodiment of the present invention proposes a sleeper rail production line for pouring concrete into the inner cavity of a sleeper rail blank, comprising a processing frame 1, the processing frame 1 having a processing space 101; a conveying frame 2 is partially located in the processing space 101, the conveying frame 2 is used to convey the sleepers, and the conveying direction of the conveying frame 2 for the sleepers is longitudinal, and the sleepers enter or leave the processing space 101 after moving; a pouring piece 3 is transversely slidably arranged on the processing frame 1, and is located in the processing space 101. The pouring piece 3 has a pouring port 301, and the pouring piece 3 is used to abut against one end of the sleeper rail blank after moving, and the pouring port 301 is used to face the inner cavity of the sleeper rail blank.

[0045] In this embodiment, considering that the efficiency of finishing after the secondary pouring of concrete sleeper rail blanks by the secondary pouring method in the prior art is low, the smoothing effect is not ideal, and there are still many cases where manual closing is required, a processing frame 1 is provided in this solution, and basic devices such as a lifting device and a moving device are provided on the processing frame 1, which can be used to perform hoisting operations on the sleeper rail blanks. On the other hand, a conveying frame 2 is also provided, and the sleeper rail blanks can be hoisted into the processing space 101 according to actual conditions or transported to the processing space 101 by the conveying frame 2. In the early processing process, an X-shaped grouting port is processed on one side of the sleeper rail blank, and an air outlet is processed on the other side, which respectively act on the two side openings of the inner cavity, and an exhaust device is provided on one side of the air outlet. This solution focuses on the description of the grouting device side. When the workpiece is transported to the processing space 101, the conveying frame 2 stops conveying the sleeper rail blank, and the pouring piece 3 slides to the pouring port 301 to abut against the entrance at one end of the inner cavity, and pours into the interior. The size of the pouring port 301 is larger than the entrance at one end of the inner cavity, which can more fully pour the inner cavity and prevent leakage. The design adopts an automated pouring method, which greatly reduces the use of manual labor. The direct connection between the pouring port 301 and the entrance of the inner cavity also prevents leakage of concrete and makes the filling more sufficient. The pouring piece 3 adopts an electric grouting machine with a grouting nozzle of corresponding size.

[0046] Furthermore, the positioning clamp 4 is lifted and slidably arranged on the processing frame 1, and the positioning clamp 4 has a limit clamping groove 401. After the positioning clamp 4 moves downward, the limit clamping groove 401 is used to clamp on the sleeper rail blank.

[0047] In this embodiment, a positioning card 4 is provided on the processing frame 1 for lifting and sliding. The positioning card 4 has a limit slot 401, and the positioning card 4 and the pouring member 3 are located on the same straight line in the horizontal direction. The limit slot 401 has the same shape and size as the outer contour of the sleeper rail. When the positioning card 4 is lowered and clamped on the sleeper rail blank, it can perform a small correction on the sleeper rail blank that has been placed and transported to the position, so that the pouring port 301 can be accurately aligned with the entrance of the inner cavity of the sleeper rail blank, further improving the stability and efficiency of concrete pouring.

[0048] Furthermore, the filling port 301 includes a plurality of diversion portions 302, which are arranged in a circle and intersect with each other, and also includes a scraper member 5 which is slidably and swingably arranged in the diversion portion 302, and the scraper member 5 has an arc scraper portion 501 and a flat scraper portion 502, and the arc scraper portion 501 and the flat scraper portion 502 are adjacently arranged. After the scraper member 5 swings, the arc scraper portion 501 extends out or retracts into the filling port 301, and the flat scraper portion 502 is flush with the filling port 301 or retracts into the filling port 301.

[0049] In this embodiment, the pouring port 301 includes a plurality of diversion parts 302, each of which together forms an X-shape with the same shape as the entrance of the inner cavity of the sleeper rail blank. A scraper 5 is slidably arranged in each diversion part 302, and the scraper 5 has an arc scraper part 501 and a flat scraper part 502. In the specific pouring process, a small amount of overflowing excessive pouring method is adopted. After the scraper 5 swings, the arc scraper part 501 can extend out of the pouring port 301, that is, it can extend into the entrance of the inner cavity of the sleeper rail blank. As the scraper The sliding of part 5 can smear the concrete at the entrance of the inner cavity of the sleeper rail blank into an arc-shaped groove. The effect of this processing method is, on the one hand, that it can compact the concrete at the entrance of the inner cavity of the sleeper rail blank to prevent the formation of cavities or overflow therein; on the other hand, it can help to backfill the remaining or overflowed concrete into the arc-shaped groove when the flat scraper part 502 swings to be flush with the pouring port 301 during the next movement process, and scrape off the excess concrete, finally forming a flat surface without hollows or missing materials.

[0050] Furthermore, the arc-shaped scraping portion 501 has a notch portion 503 .

[0051] In this embodiment, a notch portion 503 is provided on the arc-shaped scraper portion 501. The notch portion 503 can retain a portion of concrete material in the middle part of the concrete at the entrance of the inner cavity of the sleeper rail blank scraped by the arc-shaped scraper portion 501 for backfilling of the flat plate scraper portion 502 in the later stage. At the same time, since the amount of concrete material on the retained side is quantitatively determined by the notch portion 503 of the same size, the backfilling can have the same amount of material each time, and the amount of material required and remaining during leveling and scraping can be controlled within a certain range, so that the scraping and leveling operations can be performed more accurately and stably, and it is also convenient to set up a corresponding material collection and processing device for processing it in the later stage.

[0052] Furthermore, the filling port 301 has four diversion parts 302, and one end of the four diversion parts 302 intersects, the scraper 5 is divided into a first scraper 504 and a second scraper 505, the first scraper 504 and the second scraper 505 are each arranged in pairs, and the first scraper 504 and the second scraper 505 are respectively arranged in two adjacent diversion parts 302, after the two first scrapers 504 slide to the intersection of the diversion parts 302, the flat scraper parts 502 of the two first scrapers 504 abut against each other, after the two second scrapers 505 slide to the intersection of the diversion parts 302, the flat scraper parts 502 of the second scraper 505 abut against the first scraper 504.

[0053] In this embodiment, it is considered that when multiple scrapers 5 slide to the intersection of the diversion part 302, it is difficult to achieve a smoothing effect at the intersection, and a large amount of concrete material will remain, which will cause quality problems in the final product. In this solution, the scraper 5 is divided into a first scraper 504 and a second scraper 505. The first scraper 504 and the second scraper 505 have the same main structure, both of which have an arc-shaped scraper part 501 and a flat scraper part 502. Through a certain adjustment of the size, the states of the two at the intersection of the diversion part 302 are slightly different. The two relatively sliding first scrapers 504 and the two relatively sliding second scrapers 505 are respectively located on two lines of the X-shaped pouring port 301 , and it is set that when the scraper 5 is away from the intersection, the arc-shaped scraper portion 501 is extended, and when it moves close to the intersection, the flat scraper portion 502 is flush with the pouring port 301. When completely converged, the flat scraper portions 502 of the two first scrapers 504 directly abut to complete the complete smoothing of a line, and the flat scraper portions 502 of the two second scrapers 505 abut against the side walls of the two first scrapers 504, achieving complete smoothing of the line where the second scrapers 505 are located, and the abutment of the flat scraper portions 502 can also prevent the occurrence of concrete residue or incomplete smoothing at the intersection, further achieving good pouring and smoothing effects of the present device.

[0054] Furthermore, the filling piece 3 has a filling space 303 inside, and also includes a partition plate 6. The partition plate 6 is arranged in the filling space 303 and divides the filling space 303 into a filling cavity 304 and an isolation cavity 305. The filling port 301 is located at one end of the filling cavity 304.

[0055] In this embodiment, considering that a driving member needs to be provided inside the pouring member 3 to drive the movement of the scraper member 5, the driving device and the transmission device need to work in a relatively stable environment and also need a good setting position. In this scheme, a partition plate 6 is provided in the pouring space 303 to divide the pouring space 303. The pouring chamber 304 is mainly used to circulate concrete so that the concrete can fully flow into the inner cavity of the sleeper rail blank. The isolation chamber 305 is used to place the main power and transmission mechanism, thereby ensuring the stability of the working environment. There will be some connecting holes between the two chambers, and a small range of movable sealing treatment will be performed at the connecting holes, such as sliding seals, etc., so as to achieve a stable working environment while ensuring a good transmission effect of the device, thereby reducing the failure rate of the device.

[0056] Furthermore, it also includes a first connecting rod 7 hinged to the scraper 5; a second connecting rod 8 hinged to the scraper 5 and located on one side of the first connecting rod 7; a third connecting rod 9 hinged to the first connecting rod 7 at one end and hinged to the second connecting rod 8 at the other end, and the third connecting rod 9 has an arc groove 901; a transmission member 10 is slidably set on the partition plate 6, and the transmission member 10 has a first guide groove 1001 perpendicular to the direction of the diversion part 302; the guide member 11 has a first sliding part 1101 and a second sliding part 1102, the first sliding part 1101 is slidably set in the first guide groove 1001, the second sliding part 1102 is slidably set in the arc groove 901, and the second sliding part 1102 drives the scraper 5 to swing after sliding in the arc groove 901.

[0057] In the present embodiment, a specific transmission method for the scraper 5 is involved. For ease of understanding, the field of view is described with the direction of view being the same as the entrance direction of the inner cavity of the sleeper rail blank. The first scraper 504 and the second scraper 505 on the left are a group that are synchronously transmitted, and the first scraper 504 and the second scraper 505 on the right are a group that are synchronously transmitted. Since there is a slight difference in the length of one end of the intersection of the first scraper 504 and the second scraper 505, the synchronous drive can achieve a simultaneous intersection of the two when the initial movement setting is made. The specific transmission method is that a first connecting rod 7 and a second connecting rod 8 are hinged on each scraper member 5, and a third connecting rod 9 is also provided which is hinged with the first connecting rod 7 and the second connecting rod 8 at the same time. The movement and swinging state of the scraper member 5 can be realized by driving both ends of the third connecting rod 9 and driving the third connecting rod 9 to move. An arc groove 901 is provided on the third connecting rod 9, and a guide member 11 is also provided. When the guide member 11 slides to the end of the arc groove 901 away from the intersection of the diverter portion 302, the scraper member 5 is driven to swing to the state where the arc scraper portion 501 is working, and vice versa, it swings to the state of the flat scraper portion 502. In addition, a transmission member 10 is provided as a source of transmission power. The transmission member 10 itself moves stably left and right, and there are two transmission members 10, which move closer or farther from each other, and are used to drive the left and right pairs of first scraper members 504 and second scraper members 505. When the transmission member 10 slides, the scraper member 5 is driven to slide by the force component in the direction of the diverter 302. Considering that the distance between the guide member 11 and the transmission member 10 will change, the present solution is provided with a first guide groove 1001 on the transmission member 10, and the guide member 11 can slide in the first guide groove 1001, so as to realize a smooth driving transmission process. This transmission mode can realize stable sliding and swinging motion of the scraper member 5 while simplifying the power device. At the same time, since there is no large load in the working environment, this device is sufficient to achieve good transmission work.

[0058] Furthermore, the transmission member 10 also has a second guide groove 1002, the first guide groove 1001 and the second guide groove 1002 are adjacently arranged, a guide member 11 is slidably arranged on the third connecting rod 9 arranged on the scraper member 5, and the two guide members 11 on the vertically adjacent first scraper member 504 and the second scraper member 505 are slidably arranged in the first guide groove 1001 and the second guide groove 1002 respectively.

[0059] In this embodiment, the third connecting rod 9 is provided on both the first scraper 504 and the second scraper 505, and a guide member 11 is slidably provided on each third connecting rod 9. Considering that the sliding directions of the first scraper 504 and the second scraper 505 on the same side are different, the present solution provides staggered first guide grooves 1001 and second guide grooves 1002 on the transmission member 10, respectively providing sliding channels for the two guide members 11, so that the operation of the device is more reasonable and the work is more stable.

[0060] Furthermore, it also includes a bidirectional screw rod 12 rotatably set on the partition plate 6, located in the isolation chamber 305; the transmission member 10 is set on the nut 13, the nut 13 has a threaded portion, and the threaded portion is threadedly matched with the bidirectional screw rod 12; the output end of the rotating drive member is set on the bidirectional screw rod 12, driving the bidirectional screw rod 12 to rotate.

[0061] In this embodiment, the two transmission members 10 with opposite moving directions are driven to move by the cooperation of the bidirectional screw rod 12 and the nut 13, and a rotating driving member and a screw rod and nut 13 are arranged in the isolation chamber 305. On the one hand, the movement of the transmission members 10 on both sides is made more precise and stable, so that the flat scraper part 502 can perform a better final finishing and smoothing work, and the arc scraper part 501 can accurately complete the entire work process.

[0062] Furthermore, the partition plate 6 also has a plurality of feed ports 601 , and also includes a feed pipe 14 for pouring concrete into the pouring cavity 304 through the feed ports 601 .

[0063] In this embodiment, by setting up a feed pipe 14 to pour concrete into the pouring chamber 304, the safety of the isolation chamber 305 is further achieved. At the same time, the position of the concrete discharge is closer to the pouring port 301, and the pouring and stopping of the pouring action can be carried out faster, further improving the working efficiency of the device and the pouring finishing effect.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
