[0002] In the process of realizing the automated demoulding of sleepers (especially double-block sleepers), it is necessary to obtain and flip the undemolded sleepers, and transfer them to the demoulding platform for demoulding. After the demoulding is completed, the mold and the sleeper product are transferred to the corresponding next station respectively. In the process of realizing the automated demoulding of sleepers, it is necessary to use a flipping device to accurately obtain the undemolded sleepers and transfer them to the demoulding platform. After demoulding, the mold is flipped and removed from the demoulding platform by a flipping device. How to accurately obtain and transfer the mold is the key to realizing the automation of the flipping device for sleeper demoulding. Therefore, higher requirements are placed on the mechanical properties of the flipping device for sleeper demoulding.

[0003] In the actual production process, in order to make better use of space, the flipping equipment for sleeper demoulding is often set between two parallel transfer lines; at the same time, in order to take into account the convenient transfer of the sleepers after demoulding, the flipping equipment needs to be rotated in the horizontal direction during the transfer process according to the setting of the production line, so as to better meet the needs of automated production.

[0004] In addition, a large number of sleepers and small prefabricated parts are needed in the construction of high-speed railways.

In the specific implementation, the first drive unit 24 can be selectively an electric motor or a hydraulic motor, preferably the first drive unit 24 is an electric motor. The slewing bearing is selectively an outer gear ring slewing bearing, and the transmission wheel is a gear adapted to the outer gear ring slewing bearing, and the gear is transmission-connected to the power output shaft of the motor and meshed with the outer gear ring slewing bearing. Driven by the motor, the second mounting seat 22 can be rotated relative to the first mounting seat 21. Then, the demoulding turning device 10 for sleepers can drive the transported mold or the undemolded sleeper to rotate, so as to better meet the use requirements of production lines with different arrangements.

[0094] It should be explained that the "lifting power assembly" in the present application refers to a power assembly that can cause the lifting and pushing assembly 4 to implement the pushing and pulling function. In specific implementation, the lifting power assembly can be selectively made to be a power assembly including a hydraulic pump and a telescopic cylinder; the lifting power assembly can also be selectively made to be a power assembly including an electric motor and a transmission assembly; the lifting power assembly can also be made to be a screw lifting platform.

[0097] It should be explained that the "ring chain" in this application refers to a chain that is connected end to end to form a ring for transmission. In specific implementation, the length of the ring chain can be selectively set according to actual design needs. In addition, the "non-ring chain" in this application refers to a chain that is not connected at both ends and is used for transmission.

[0098] It should be noted that the second driving unit 51 in the present application is not specifically limited, and it can be any unit that can implement power drive.

Further, the second driven wheel 532 and the fifth driven wheel 541 are in the same vertical plane, and the second driven wheel 532 can be connected by a ring chain. Then, under the drive of the second driving unit 51, the first transmission shaft 53 and the second transmission shaft 54 ​​can be rotated synchronously, and the driven wheels arranged thereon are driven to rotate, and then the second mounting frame 3 is driven by the non-ring chain.

[0101] Based on the above scheme, under the drive of the second driving unit 51, the scissor-type push-pull assembly can be driven to rise and fall relatively quickly through the sprocket chain transmission mode, and the working efficiency of the rail sleeper demoulding flipping device 10 can also be indirectly improved. In addition, by adopting the above-mentioned sprocket chain transmission mode, the third driven wheel 533, the fourth driven wheel 534, the sixth driven wheel 542 and the seventh driven wheel 543 can have better synchronization, thereby better realizing the lifting function and position accuracy of the second mounting frame 3, so as to realize the automatic operation of the rail sleeper demoulding flipping device 10.

And an eighth driven wheel 551 and a ninth driven wheel 552, both of which are sprockets, are installed on the first shaft 55. The eighth driven wheel 551 is located above the connection between the first non-annular chain and the second mounting frame 3 and below the third driven wheel 533; the third driven wheel 533 is transmission-connected to the eighth driven wheel 551 via the first non-annular chain.

The second shaft 56 is provided with a tenth driven wheel 561 and an eleventh driven wheel 562, both of which are sprockets. The tenth driven wheel 561 is located above the connection between the third non-annular chain and the second mounting frame 3 and below the sixth driven wheel 542; the sixth driven wheel 542 is transmission-connected to the tenth driven wheel 561 via the third non-annular chain.

By limiting the positions of the sprockets on the first shaft 55 and the second shaft 56 as mentioned above, the transmission of the non-annular chain can be better realized, thereby improving the reliability of the lifting and lowering transmission of the flipping device 10 for rail sleeper demoulding.

As a convertible embodiment, the guide rod 91 can also be selectively fixedly connected to one side of the supporting bracket 222, and the guide sleeve 92 can be fixedly connected to one side of the second mounting frame 3.

[0107] The present application provides a guide assembly 9 including a guide rod 91 and a guide sleeve 92, thereby ensuring the position accuracy of the flipping device 10 for demoulding the sleeper during the process of the second mounting frame 3 being pushed and pulled along with the lifting and pushing assembly 4. In addition, the present application connects one of the guide sleeve 92 and the guide rod 91 to the bearing bracket 222, and the other of the guide sleeve 92 and the guide rod 91 to the second mounting frame 3, thereby effectively reducing the deformation caused by the inertial force of the unit formed by the second mounting seat 22, the lifting and pushing assembly 4, and the second mounting frame 3 during the rotation process under the action of the guide assembly 9; thereby improving the rigidity and stability between the bearing bracket 222 and the second mounting frame 3, and better meeting the accuracy requirements of the flipping device 10 for demoulding the sleeper.

[0133] The present application also provides a preform production line, including the demoulding device 100 and the first transfer line 501 and the second transfer line 502 involved in some of the aforementioned embodiments or examples. Fig. 9 As shown, the first transfer line 501 extends from the previous station to the right below the running track of the demoulding turning device 10 for sleepers, and the first transfer line 501 is configured to transfer the mold or the un-demolded sleeper to the working area of ​​the demoulding turning device 10 for sleepers; the second transfer line 502 extends from the working area of ​​the demoulding turning device 10 for sleepers to the next station. It should be pointed out that the previous station can be selectively a prefabricated part maintenance station or a small prefabricated part turning and demoulding station.

[0134] During specific operation, the first transfer line 501 can transfer the un-demolded sleepers to the working area of ​​the demoulding device 100. By controlling the demoulding device 100, the un-demolded sleepers can be obtained from the first transfer line 501, and the un-demolded sleepers are flipped and placed on the demoulding platform 20 by the demoulding device 100, and the sleepers are demoulded by the demoulding platform 20. After the demoulding is completed, the mold is obtained from the demoulding platform 20 and flipped by the demoulding device 100, and the demoulded mold is further transferred to the second transfer line 502. Further, under the transfer of the second transfer line 502, the demoulded mold is transferred to the next station of the production line.

[0135] When the aforementioned production line is a composite preform production line, that is, the production line can produce preforms of different types, the demoulding device 100 can be selectively used only for the function of transferring the mold.

[0136] In specific implementation, the products produced by the composite prefabricated part production line can be selectively sleepers (especially double-block sleepers) and small prefabricated parts.

[0137] When the products produced by the composite preform production line are small preforms, a plurality of small preform molds are fixed on the mold table, and the small preforms fixed on the mold table are flipped and demolded by the small preform flipping and demolding device 301. After demolding, the mold table carrying the mold is transferred to the first transfer line 501, and under the transfer of the first transfer line 501, the mold table carrying the mold is transferred to the working area of ​​the demolding device 100. The mold table carrying the mold is further transferred to the second transfer line 502 by the demolding device 100, and the mold table carrying the mold is transferred to the next station (for example, the mold cleaning station) by the second transfer line 502. That is, when the products produced by the production line are small preforms, the demolding device 100 only serves the function of transferring the mold. Then by Fig. 9 As shown, the production line also includes a small preform stacking station 302, and the small preform flipping and demoulding device 301 is connected to the small preform stacking station 302 via a small preform transfer line 504; during specific operation, the preforms demoulded by the small preform flipping and demoulding device 301 are transferred to the small preform stacking station 302 via the small preform transfer line 504.

[0138] When the product produced by the composite prefabricated part production line is a sleeper, the undemolded sleeper is transferred to the working area of ​​the sleeper demoulding turning device 10 via the first transfer line 501. The undemolded sleeper is further obtained from the first transfer line 501 by the sleeper demoulding turning device 10, and the undemolded sleeper is turned over and placed on the demoulding platform 20, and the sleeper is further demoulded by the demoulding platform 20. After the demoulding is completed, the sleeper mold is further obtained and turned over by the sleeper demoulding turning device 10, and the sleeper mold is transferred to the second transfer line 502, and the second transfer line 502 transfers the sleeper mold to the next station (for example, the mold cleaning station).

In specific implementation, the turning device 10 for demoulding the sleeper can be turned over first and then transported; or it can be turned over first and then transported; it can also be turned over during the transport process. In order to improve the production efficiency of the production line, it is preferred that the turning device 10 for demoulding the sleeper is turned over during the transport process.

[0140] In specific implementation, the production line may also selectively include a sleeper inspection station 401, a sleeper stacking station 402 and a third transfer line 503. Fig. 9As shown, the third transfer line 503 passes through the sleeper inspection station 401 from the working area of ​​the sleeper demoulding turning device 10 and extends to the sleeper palletizing station 402. In specific operation, the demoulded sleepers are transferred to the sleeper inspection station 401 via the third transfer line 503, and the inspected sleepers are then transferred to the sleeper palletizing station 402 via the third transfer line 503 for palletizing.

[0141] As a convertible embodiment, the production line can also be selectively made into a sleeper production line only. The difference from the above-mentioned composite preform production line is that the production line does not include the small preform flipping and demoulding equipment 301, the small preform transfer line 504 and the small preform stacking station 302.

[0142] It should also be noted that although the present application uses the production of small prefabricated parts and sleepers as an example, it is not limited to the above-mentioned prefabricated products.
