Description

Technical Field

[0001] This utility model relates to the field of railway sleeper production, specifically to a double-block railway sleeper demolding table, a railway sleeper demolding system, and a prefabrication production line. Background Technology

[0002] Double-block sleepers are the mainstream track bed structure for urban rail transit and one of the most widely used ballastless track structures in high-speed railways. This structure is widely used due to its simple structure, fast construction speed, and lower cost compared to track slabs. As a precast component, its actual production process requires processes such as material placement, curing, and demolding.

[0003] In existing double-block sleeper demolding processes, the mold needs to be flipped and placed on a demolding table. Further force is applied to the mold to separate the sleeper from it. However, in actual production, to ensure successful demolding, the mold is often lifted to a set height using an airbag and then allowed to fall freely. Demolding is achieved through impact with the support platform. However, because it's difficult to accurately determine if demolding has been successful, multiple impacts are often required. Furthermore, due to the poor hardness of the cured sleepers, existing demolding methods easily cause cracks, severely impacting the quality and yield of the leveling process, resulting in significant waste. Utility Model Content

[0004] The purpose of this application is at least to provide a sleeper demolding table that can reduce product cracking during the demolding process of two-piece sleepers and improve the product qualification rate. This is achieved through the following solution:

[0005] Firstly, the double-block sleeper demolding table provided in this application includes a mold support device, a sleeper bearing beam, a sleeper detection unit, and a control unit. Two mold support devices are arranged side-by-side, and at least one mold support device is equipped with a vibration motor; two sleeper bearing beams are arranged side-by-side between the two mold support devices; at least one sleeper bearing beam is equipped with a sleeper detection unit configured to detect whether the sleeper has detached from the sleeper mold; the vibration motor is signal-connected to and controlled by the control unit, and the sleeper detection unit is signal-connected to the control unit; when the sleeper detection unit detects that the sleeper has detached from the mold, the control unit controls the vibration motor to stop working.

[0006] This application utilizes a vibrating motor to apply small-amplitude, high-frequency vibrations to the mold during sleeper demolding, thereby enabling the sleeper to detach from the mold more effectively. Verification has shown that this demolding method effectively reduces the impact of sleeper demolding on sleeper quality and significantly improves product yield. Secondly, this application incorporates a sleeper detection unit to monitor the demolding status and promptly provide information to the control unit. The control unit then controls the vibrating motor to stop operation in a timely manner, ensuring timely vibration cessation while guaranteeing complete sleeper demolding.

[0007] In some embodiments of this application, the sleeper detection unit includes a mounting base, an actuating element, an elastic element, and a position detection component. The mounting base is mounted on the sleeper support beam. The actuating element is connected to the mounting base via the elastic element. The actuating element has a first position extending beyond the support surface on the sleeper support beam and a second position having a downward movement of a predetermined distance. The position detection component is mounted directly below the actuating element and is signal-connected to the control unit. The position detection component is configured to detect whether the actuating element is in the second position.

[0008] This application includes a sleeper detection unit comprising an actuating element, an elastic element, and a position detection component. When the sleeper is demolded, the actuating element is pressed down, and the position detection component collects the position information of the demolded sleeper. This information can then be transmitted to the control unit in a timely manner to control the vibration motor. This has the advantages of fast response and timely control.

[0009] In some embodiments of this application, multiple sleeper detection units are installed at intervals on the side wall of the sleeper-bearing beam. In the demolding state, each sleeper detection unit corresponds to one sleeper, and the trigger is directly opposite one sleeper.

[0010] In some embodiments of this application, each sleeper-bearing crossbeam is provided with multiple sleeper detection units, and the sleeper detection units are located on the side directly opposite another sleeper-bearing crossbeam. The number of sleeper detection units provided on each sleeper-bearing crossbeam is any value from 1 to 6. By providing multiple sleeper detection units, this application can detect the demolding status of multiple demolded sleepers one by one.

[0011] In some embodiments of this application, the sleeper detection unit further includes guide rods. Two guide rods are vertically mounted on the mounting base, and the elastic element is a helical spring. Each guide rod is fitted with a helical spring. One end of the helical spring abuts against the mounting base, and the other end of the helical spring abuts against the trigger. The trigger and the guide rod are slidably connected.

[0012] In some embodiments of this application, the mold support device includes a mounting support, a mold support structure, and a vibration damping unit. The mold support structure is mounted directly above the mounting support via the vibration damping unit; the vibration motor is mounted on the mold support component. By mounting the mold support structure on the mounting support via the vibration damping unit and mounting the vibration motor on the mold support component, the dynamic load generated by the vibration motor can be isolated from the mounting support by the vibration damping unit, making the vibration force generated by the vibration motor more concentrated and better meeting the demolding requirements of the sleeper.

[0013] In some embodiments of this application, the upper surface of the mold support structure has a mold support plane, and the upper surface of the sleeper support beam has a sleeper support plane. The vertical height of the mold support plane is higher than the vertical height of the sleeper support surface, and the height difference is 10-50mm. By limiting the height difference between the mold support plane and the sleeper support surface, this application can minimize the drop after the sleeper detaches from the mold, and effectively reduce the probability of damage to the sleeper during the detachment process.

[0014] In some embodiments of this application, the upper surface of the mold support structure is provided with a plurality of spaced first limiting guide structures, and the plurality of first limiting guide structures are staggered relative to each other; in the demolding state, some of the first limiting guide structures are located inside the sleeper mold, and some of the first limiting guide structures are located outside the sleeper mold, and the plurality of first limiting guide structures are configured to constrain the sleeper mold to a set position; and / or, at least one second limiting guide structure is provided on the outer sides of both ends of the mold support structure, and on each second limiting guide structure, the second limiting guide structure is configured to constrain the sleeper mold to a set demolding position.

[0015] This application, through the provision of a first limiting guide structure and / or a second limiting guide structure, can guide the placement of undemolded sleepers during the process, reducing placement difficulty and the positioning accuracy requirements of the transfer equipment, and facilitating automated operation. Furthermore, the restriction provided by the first limiting guide structure and / or the second limiting guide structure can prevent large displacement of the sleeper mold during vibration, allowing the sleeper demolding table to smoothly implement the demolding process.

[0016] Secondly, this application provides a dual-block sleeper demolding system, including a dual-block sleeper demolding platform and a mold transfer device as described in any of the foregoing embodiments. The dual-block sleeper demolding platform is located directly below the working area of ​​the mold transfer device. The mold transfer device is configured to transfer undemolded molds to the dual-block sleeper demolding device and to transfer demolded molds away.

[0017] Thirdly, this application provides a precast component production line, including a double-block sleeper demolding table as described in some of the foregoing embodiments, or a double-block sleeper demolding system as described in some of the foregoing embodiments; it also includes a sleeper transfer device configured to transfer the demolded sleepers to a set position.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The following is based on Figures 1 to 4 This invention introduces the double-block sleeper demolding table, sleeper demolding system, and precast component production line provided by this utility model.

[0035] The double-block sleeper demolding table disclosed in this application includes a mold support device 1, a sleeper support device 2, a sleeper detection unit 3, and a control unit. Two mold support devices 1 are arranged side-by-side, and each mold support device 1 is configured to support the sidewalls of the sleeper mold. Two sleeper support devices 2 are spaced apart between the two mold support devices 1. At least one mold support device 1 is equipped with a vibration motor 14, and the sleeper support device 2 is configured to support the demolded sleeper. The sleeper detection unit 3 is configured to detect whether the sleeper has been completely demolded. The sleeper detection unit 3 is signal-connected to the control unit, and the vibration motor 14 is signal-connected to and controlled by the control unit.

[0036] It should be noted that the term "mold support device" in this application is not specifically limited, and can be any device capable of supporting the sleeper mold. In specific implementation, two mold support devices 1 support the two opposite side walls of the mold.

[0037] As some preferred embodiments of this application, the sleeper support device 2 includes a support column 21 and a sleeper-bearing beam 22. The sleeper-bearing beam 22 is installed on the upper part of the support column 21 and is configured to receive the sleeper after demolding. Specifically, as follows... Figure 1As shown, each sleeper support device 2 includes two support columns 21, which are installed at intervals on the foundation. A sleeper-bearing crossbeam 22 spans across the two support columns 21. A second support plate 23 is provided on the sleeper-bearing crossbeam 22. In practice, both the sleeper-bearing crossbeam 22 and the support columns 21 are made of metal profiles.

[0038] In some preferred embodiments of this application, the sleeper detection unit 3 is installed on the sleeper bearing beam 22, and the sleeper detection unit 3 is configured to detect whether the sleeper has been demolded. After detection by the sleeper detection unit 3, a detection signal can be provided for the sleeper demolding process, so as to control the vibration duration and avoid the vibration time of the vibration motor 14 being too long or too short.

[0039] It should be noted that the sleeper detection unit in this application is not specifically limited, and it can be any detection unit capable of determining whether the sleeper has been demolded. In specific implementation, the sleeper detection unit 3 can be selectively configured to include a distance sensor or a limit switch.

[0040] As some preferred embodiments of the foregoing implementation, the sleeper detection unit 3 includes a mounting base 31, an actuating element 32, an elastic element 33, and a position detection component 34. Specifically, as follows... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple mounting bases 31 are spaced apart on the sleeper-supporting crossbeam 22 along its extension direction. Multiple actuating elements 32 are connected to the mounting bases 31 via elastic members 33; each actuating element 32 has a first position extending beyond the sleeper-supporting plane 231 of the sleeper support device 2 and a second position moving downwards a predetermined distance from the first position. A position detection component 34 is mounted on the mounting base 31 and is used to detect the vertical position of the actuating elements 32 to determine if demolding was successful. The control unit is signal-connected to the position detection component 34, and the vibrating motor 14 is signal-connected to and controlled by the control unit. In operation, after the sleeper is demolded, the actuating elements 32 are pressed down. The position signal of the actuating elements 32 is collected by the position detection component 34. When the actuating element 32 is detected to be in the second position, the collected information is transmitted to the control unit, which then determines the operating condition of the vibrating motor 14 based on the collected information.

[0041] As some preferred embodiments of the foregoing implementation, multiple sleeper detection units 3 are further installed at intervals on the side wall of the sleeper-supporting beam 22. In the demolding state, each sleeper detection unit 3 corresponds to one sleeper, and the trigger 32 is directly opposite one sleeper. Specifically, as follows... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple sleeper detection units 3 are provided on the side wall of each sleeper-bearing beam 22.

[0042] It should be noted that there is no specific limit to the number of sleeper detection units 3 included in the double-block sleeper demolding table; the number and position of the sleeper detection units 3 can be set according to the number of mold cavities of the sleeper mold. Specifically, as follows... Figure 1 , Figure 2 and Figure 4 As shown, four sleeper detection units 3 are spaced apart on each sleeper-supporting crossbeam 22, and each sleeper detection unit 3 can correspond to one double-block sleeper. As an alternative implementation, a sleeper detection unit 3 can also be selectively installed on one of the two sleeper-supporting crossbeams 22.

[0043] This application utilizes the sleeper detection unit 3 as defined above, which relies on the position detection component 34 to detect the position of the trigger 32 to obtain a signal indicating whether the sleeper has completed demolding. This information can then be provided to the control unit, which can further control the vibration motor 14 based on the demolding status. This addresses the problems of incomplete demolding or excessively long vibration time for the sleeper.

[0044] In specific implementation, the sleeper detection unit 3 further includes guide rods. Two guide rods are vertically installed on each mounting base 31, and the elastic element 33 is a helical spring. Each guide rod is fitted with a helical spring. One end of the helical spring abuts against the mounting base 31, and the other end of the helical spring abuts against the trigger 32. The trigger and the guide rod are slidably connected.

[0045] In specific implementation, the mold support device 1 includes a mounting support 11, a mold support structure 12, a vibration damping unit 13, and a vibration motor 14. The mold support structure 12 is connected to the mounting support 11 via the vibration damping unit 13, and the vibration motor 14 is mounted on the mold support structure 12. This application uses a vibration motor 14 to apply small-amplitude, high-frequency vibration to the sleeper mold, enabling the sleeper to detach smoothly from the mold and achieve successful demolding. Furthermore, by connecting the mold support structure 12 to the mounting support 11 via the vibration damping unit 13, this application effectively isolates the dynamic load generated by the vibration motor 14 from the mounting support 11 during vibration, effectively reducing noise.

[0046] It should be noted that the installation support in this application is not specifically limited; it can be any structure that meets the installation and load-bearing requirements of the vibration damping unit 13. Specifically, as shown below... Figures 1 to 4 As shown, the mounting bracket 11 is a load-bearing structure made of welded metal plates that can provide support.

[0047] The vibration damping unit in this application is not specifically limited; it can be any structure or unit that can buffer and dampen vibrations during sleeper demolding. In specific implementations, the vibration damping unit 13 is preferably a rubber spring or a vibration damping pad. Verification has shown that this arrangement can effectively reduce cracks in the sleeper products after demolding and significantly improve the pass rate of the sleeper products.

[0048] As some preferred embodiments of this application, specifically as follows: Figure 1 and Figure 4 As shown, the mold support structure 12 is generally flat and is located directly above the mounting support 11. The mold support structure 12 is connected to the mounting support 11 via two spaced-apart vibration damping units 13, and the vibration motor 14 is installed between the two vibration damping units 13. This application achieves better vibration isolation by connecting the mold support structure 12 to the mounting support 11 via two vibration damping units 13.

[0049] In specific implementation, the upper surface of the mold support structure 12 is the mold support plane 1211; the upper surface of the sleeper support device 2 is the sleeper support plane 231. The vertical height of the mold support plane 1211 is higher than the vertical height of the sleeper support surface. Preferably, the vertical height difference between the mold support plane 1211 and the sleeper support surface can be selectively set to 10mm-50mm. In specific implementation, the height difference can be any value between 10mm and 50mm, for example, it can be selectively set to any value among 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, and 50mm. It should be noted that the height difference is not limited to the values ​​listed above, and can also be any value between 10mm and 50mm, such as 11mm. This application limits the height difference between the mold support plane 1211 and the sleeper support surface, thereby reducing the drop difference after the sleeper separates from the mold. This effectively reduces damage or cracks to the sleeper during the detachment process, thereby improving the product qualification rate.

[0050] As some preferred embodiments of this application, the mold support structure 12 is further provided with a plurality of spaced first limiting guide structures 15, each first limiting guide structure 15 being provided with a first guide surface 151, the first guide surface 151 extending obliquely downward from the upper part of the first limiting guide structure 15 toward the mold support plane 1211.

[0051] In some embodiments of this application, multiple first limiting guide structures 15 are staggered relative to each other. In the demolding state, some of the first guide structures are located inside the sleeper mold, and some are located outside the sleeper mold. This arrangement provides better constraint on the mold. Specifically, as follows... Figure 1 , Figure 2 and Figure 4 As shown, the first limiting guide structure 15 is a plate-like structure, and four first limiting guide structures 15 are vertically fixed on the mold support structure 12. Two of the first limiting guide structures 15 are staggered and opposite to the other two. When placing the sleeper mold, the first limiting guide structure 15 makes it easier to place the sleeper mold on the set position of the mold support structure 12.

[0052] In specific implementation, at least one second limiting guide structure 16 can be provided on the outer sides of both ends of the mold support structure 12. Each second limiting guide structure 16 is provided with a second guide surface 161, which extends obliquely downward from the upper part of the second limiting guide structure 16 toward the mold support plane 1211. Specifically, as shown... Figure 1 , Figure 3 and Figure 4 As shown, two second limiting guide structures 16 are provided on the outer sides of both ends of each mold support structure 12, and two adjacent second limiting guide structures 16 are configured as adjacent side walls of one corner of the stop mold.

[0053] This application, through the provision of a first limiting guide structure 15 and / or a second limiting guide structure 16, can guide the placement of undemolded sleepers, reducing placement difficulty and facilitating automated operation. Furthermore, the restriction provided by the first limiting guide structure 15 and / or the second limiting guide structure 16 can prevent significant displacement of the sleeper mold during vibration, ensuring the smooth implementation of the demolding process on the sleeper demolding table.

[0054] As some preferred embodiments of this application, the mold support structure 12 further includes a first support plate 121, which is detachably mounted on the upper part of the mold support structure 12 and is made of a wear-resistant material. Specifically, as follows... Figure 1 and Figure 2 As shown, the upper part of the mold support structure 12 is provided with multiple first support plates 121, and the first support plates 121 are fixedly installed by bolt assembly and can be replaced as needed.

[0055] In addition, in the specific implementation, it will be determined by... Figure 1 and Figure 2As shown, the sleeper support device 2 also includes a second support plate 23, which is detachably installed on the upper part of the sleeper support device 2 and is also made of wear-resistant material.

[0056] As an alternative implementation, in specific implementations, the first support plate 121 and / or the second support plate 23 may be selectively omitted.

[0057] This application also provides a two-block sleeper demolding system, including a two-block sleeper demolding platform and a mold transfer device as described in any of the foregoing embodiments. The two-block sleeper demolding platform is located directly below the mold transfer device, and the mold transfer device is configured to transfer the undemolded mold to the two-block sleeper demolding platform and transfer the demolded mold away.

[0058] In actual operation, the mold transfer equipment lifts the undemolded sleeper molds onto the double-block sleeper demolding table. After the double-block sleeper demolding table demolds the sleepers, the mold transfer equipment then transfers the molds to the designated location.

[0059] It should be noted that the mold transfer equipment in this application is not specifically limited. In specific implementations, the mold transfer equipment can be an overhead crane capable of transferring undemolded double-block sleepers, or a transfer device designed specifically for undemolded double-block sleepers. In specific implementations, the mold transfer equipment can optionally have the function of flipping the sleeper mold, that is, making the sleeper opening face downwards to better achieve sleeper demolding.

[0060] This application also provides a precast component production line, including a double-block sleeper demolding table as described in any of the foregoing embodiments, or a double-block sleeper demolding system as described in some of the foregoing embodiments; it also includes a sleeper transfer device configured to transfer the demolded sleepers to a set position.

[0061] It should be noted that there are no specific restrictions on the sleeper transfer equipment; it can be any device capable of transferring sleeper molds. In specific implementation, the sleeper transfer equipment may optionally include a transfer trolley with a lifting platform. During operation, the sleeper transfer equipment moves between the two sleeper support devices 2, and uses the lifting platform to retrieve the demolded sleepers from the sleeper support devices 2, further transferring the demolded double-block sleepers to the designated position.

[0062] In specific implementation, the sleeper transfer equipment can be optionally an automated transfer vehicle (e.g., an AGV or a rail transfer vehicle) that includes a lifting platform. As an alternative implementation, the automated transfer vehicle can also be optionally made without a lifting platform. In specific operation, the demolded sleepers can be transferred to the automated transfer vehicle by other transfer equipment, and then the sleepers can be further transferred to the set position by the automated transfer vehicle.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
