Description

TECHNICAL FIELD

[0001] The utility model relates to prefabricated part production technical field, concretely relates to turnover device for stripping, stripping equipment and prefabricated part production line. BACKGROUND

[0002] The prefabricated part needs to be clothed in the cavity of the mould in the production process, and needs to be turned over and stripped after completing processes such as cloth distribution and maintenance. Since the use field of the prefabricated part is relatively wide, and the use amount is relatively large, how to improve the turnover and stripping efficiency of the prefabricated part is of great significance to the production of the prefabricated part. Realizing the automatic production of the prefabricated part has become the current research emphasis. Especially in the turnover and stripping process of the prefabricated part, the working precision of the mechanical structure of the related equipment is crucial to realize the automatic stripping of the prefabricated part.

[0003] Specifically, for example, in the automatic stripping process of the double-block sleeper, the prefabricated part that has not been stripped needs to be obtained and turned over, and then transported to the stripping platform for stripping, and after the stripping is completed, the mould is transported to the next station. In this process, the turnover device needs to accurately obtain the prefabricated part that has not been stripped and transport it to the stripping platform, and after stripping, the turnover device turns over the mould and transports it away from the stripping platform. How to accurately obtain and transport the mould puts high requirements on the mechanical structure design of the turnover device for stripping.

[0004] In actual production process, in order to better utilize the space, the turnover device for stripping is often arranged between two parallel transport lines, and at the same time, in order to facilitate the transportation of the prefabricated part after stripping, the turnover device needs to be rotated by a set angle in the horizontal direction according to the setting of the production line during the transportation process, so as to better meet the needs of automatic production.

[0005] In addition, in some fields, there are many types of prefabricated parts produced, for example, a large number of prefabricated sleeper and small prefabricated parts are needed in the construction of high-speed railway. If a composite prefabricated part production line that can meet the production needs of sleepers and small prefabricated parts at the same time and a turnover device for stripping that can meet the needs of the composite prefabricated part production line can be developed, it will be of great significance.

Each wheel on each end beam 12 is tractably connected to a drive motor 13, enabling the first mounting frame 1 to allow the demolding overturning device 10 to move within a designated working area as needed, thus giving the demolding overturning device 10 a transfer function. In specific implementations, the supporting beams 11 can be selectively made from profiles that meet load-bearing requirements, or they can be box beams welded from sheet metal. Similarly, the end beams 12 can also be made from profiles or sheet metal.

[0083] This application enables the demolding overturning device 10 to have a walking function by providing a walking wheel on the end beam 12 of the first mounting frame 1, and at least one walking wheel is transmittably connected to a walking drive motor 13. This allows the demolding overturning device 10 to not only have rotation and overturning functions, but also transfer functions, which can better meet the usage requirements of the precast component production line.

[0084] The term "first mounting base" in this application is not specifically limited, and it can be any structural form capable of accommodating the installation of the second mounting base 22. In specific implementations, such as... Figures 1 to 7 As shown, the first mounting base 21 includes a sleeve and a mounting flange fixed to one end of the sleeve. The mounting flange of the first mounting base 21 is hinged to the lower part of the first mounting frame 1 via multiple hinged seats. As an alternative embodiment, the mounting flange of the first mounting base 21 can also be selectively connected to the lower part of the first mounting frame 1 via multiple sets of standard connection assemblies (e.g., connection assemblies including bolts and nuts).

[0085] Furthermore, the positions of the first mounting base 21 and the first mounting bracket 1 in this application are not specifically limited; they can be any arrangement that meets the installation requirements of the second mounting base 22. In specific implementations, the first mounting base 21 can be selectively installed in the middle of the first mounting bracket 1 (not shown in the figure), or the first mounting base 21 can be installed below the middle of the first mounting bracket 1 (e.g., ...). Figures 1 to 7The first mounting seat 21 is selectively arranged integrally with the first mounting frame 1 as a transformable embodiment.

[0086] It should be further pointed out that the "second mounting seat" in the present application is not specifically limited, which can be any structure meeting the installation and bearing requirements. The second mounting seat 22 is rotatable relative to the first mounting seat 21, so that the second mounting seat 22 can be rotated relative to the first mounting seat 21 under the driving of the driving unit, and the stripping turnover device 10 can rotate the transported mold in use to better meet the production requirements. In specific implementation, the second mounting seat 22 comprises a rotary body 221 and a bearing bracket 222. The upper end of the rotary body 221 is drivingly connected to the first mounting seat 21 through a rotary bearing, and the lower end of the rotary body 221 penetrates through the first mounting seat 21 and is connected to the bearing bracket 222. Specifically, as shown in Figures 1 to 7 the rotary body 221 is in a cylindrical structure as a whole, and the rotary body 221 is also provided with a mounting flange corresponding to the mounting flange on the first mounting seat 21. The first mounting seat 21 is arranged outside the second mounting seat 22, and the first mounting seat 21 is connected to the second mounting seat 22 through a rotary bearing (not shown in the figure) (specifically, the mounting flange on the first mounting seat 21 is connected to the mounting flange on the rotary body 221 through the rotary bearing). Since the first mounting seat 21 and the second mounting seat 22 are connected through the rotary bearing, the second mounting seat 22 can be rotated relative to the first mounting seat 21.

[0087] It should be further pointed out that the structure of the "bearing bracket" in the present application is not specifically limited, which can be any structure meeting the bearing and installation requirements of the lifting and pulling component 4. In specific implementation, as shown in Figures 1 to 7 the bearing bracket 222 is in a square frame structure as a whole, and the middle part of the square frame structure is connected to the lower part of the rotary body 221. The second mounting frame 3 is located below the bearing bracket 222, and the second mounting frame 3 is connected to the lower part of the bearing bracket 222 through the lifting and pulling component 4.

In specific implementation, the lifting and pulling component 4 can be a telescopic cylinder assembly, a screw lifting platform, or a scissor-type pulling component, etc. Specifically, as shown in Figure 1 the second mounting frame 3 is connected to the lower part of the bearing bracket 222 through the scissor-type pulling component.

[0089] It should be noted that the structure of the "first turnover unit" in the present application is not specifically limited, and it can be any unit that can cooperate with the second turnover unit 62 to obtain and turn over the mold. Similarly, the structure of the "second turnover unit" in the present application is not specifically limited, and it can be any unit that can cooperate with the first turnover unit 61 to obtain and turn over the mold.

[0090] The present application connects the second mounting bracket 3 with the second mounting seat 22 through the lifting and pulling assembly 4, and then under the action of the lifting and pulling assembly 4, the second mounting seat 22 can be lifted according to the working condition requirements, and then drives the first turnover unit 61 and the second turnover unit 62 to lift. To better meet the position adjustment of the mold during transfer and turnover. In addition, the present application installs the first mounting seat 21 on the first mounting bracket 1, so that the second mounting seat 22 is rotatably connected with the first mounting seat 21, and then the second mounting seat 22 can be rotated relative to the first mounting seat 21 as needed to adjust the position of the transferred mold, and then better adapt to production lines with different settings, so that the demolding turnover device 10 can have better universal applicability.

[0091] As some preferred embodiments of the present application, the demolding turnover device 10 further comprises a first driving unit 24 and a transmission wheel (not shown in the figure), the power output shaft of the first driving unit 24 is in driving connection with the transmission wheel, and the transmission wheel is in driving connection with the slewing bearing. In specific implementation, the first driving unit 24 can be selectively an electric motor or a hydraulic motor, and preferably an electric motor. Specifically, the first driving unit 24 is installed on the first mounting bracket 1. The slewing bearing is selectively an outer ring slewing bearing, and the transmission wheel is a gear matched with the outer ring slewing bearing, and the gear is in driving connection with the power output shaft of the electric motor and is in meshing connection with the outer ring slewing bearing. Under the drive of the electric motor, the second mounting seat 22 can be rotated relative to the first mounting seat 21. In turn, the demolding turnover device 10 can drive the transferred mold or the unmolded preform to rotate, so as to better meet the use requirements of production lines with different arrangements. In specific implementation, in order to meet the transmission needs, the electric motor is further connected with a speed reducer, and the gear is in driving connection with the power output shaft of the speed reducer. In order to achieve the purpose of automation, the first driving unit 24 is further selectively electrically connected with and controlled by a control unit.

[0092] The present application connects the first mounting seat 21 with the second mounting seat 22 through the slewing bearing, which can better ensure the position accuracy of the demolding turnover device 10 and provide technical support for the automatic operation of the demolding turnover device 10.

[0093] As some preferred embodiments of the present application, the lifting and pulling assembly 4 is a scissor type pulling assembly. Specifically, the lower part of the bearing bracket 222 is connected with the upper end of the scissor type pulling assembly, and the upper part of the second mounting frame 3 is connected with the lower end of the scissor type pulling assembly. In order to enable the lifting and pulling assembly 4 to perform the pulling function on the second mounting frame 3, the stripping turnover device 10 further comprises a lifting power assembly, which is in transmission connection with the scissor type pulling assembly and is configured to drive the scissor type pulling assembly to extend and retract.

[0094] It should be explained that the "lifting power assembly" in the present application refers to a power assembly capable of enabling the lifting and pulling assembly 4 to perform the pulling function. In specific implementation, the lifting power assembly can be selectively a power assembly comprising a hydraulic pump and a telescopic cylinder; the lifting power assembly can also be selectively a power assembly comprising an electric motor and a transmission assembly; and the lifting power assembly can also be a screw lifting platform. In specific implementation, when the lifting power assembly comprises a transmission assembly, the transmission assembly can be selectively a transmission assembly comprising a chain and a sprocket, or a transmission assembly comprising a winding drum and a pulley, or a transmission assembly comprising a gear and a rack.

[0095] By making the lifting and pulling assembly 4 a scissor type pulling assembly, the present application can enable the bearing bracket 222 and the second mounting frame 3 to have better rigidity when the second mounting seat 22 rotates relative to the first mounting seat 21, especially to meet the torsion resistance performance of the stripping turnover device 10 during the rotation of the preform that has not been stripped, thereby better ensuring the position accuracy of the stripping turnover device 10. At the same time, the rigidity requirement of the quick rotation of the unit formed by the second mounting seat 22 and the lifting and pulling assembly 4 can be met, thereby indirectly improving the working efficiency of the stripping turnover device 10.

[0096] As some preferred embodiments of the foregoing embodiments, the lifting and pulling assembly 4 is a scissor type pulling assembly, and the lifting power assembly is a power assembly comprising a hydraulic pump and a telescopic cylinder.

The second driving unit 51 is mounted on the bearing support 222, and the driving wheel 52 is in driving connection with the power output shaft of the second driving unit 51. The first driven wheel 531, the second driven wheel 532, the third driven wheel 533 and the fourth driven wheel 534 are mounted on the first transmission shaft 53 at intervals, and the driving wheel 52 is in driving connection with the first driven wheel 531. The fifth driven wheel 541, the sixth driven wheel 542 and the seventh driven wheel 543 are mounted on the second transmission shaft 54 at intervals. In specific implementation, the second driven wheel 532, the third driven wheel 533, the fourth driven wheel 534, the fifth driven wheel 541, the sixth driven wheel 542 and the seventh driven wheel 543 are all sprockets, and the second driven wheel 532 is in driving connection with the fifth driven wheel 541 through an endless chain. The third driven wheel 533, the fourth driven wheel 534, the sixth driven wheel 542 and the seventh driven wheel 543 are respectively in meshing driving connection with a non-endless chain, and one end of each non-endless chain is connected with the second mounting frame 3, so that the third driven wheel 533, the fourth driven wheel 534, the sixth driven wheel 542 and the seventh driven wheel 543 can drive the second mounting frame 3 to rise or fall through the non-endless chain.

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

[0098] It should be pointed out that the second driving unit 51 in the present application is not specifically limited, which can be any unit capable of implementing power driving.

As an alternative implementation, the driving wheel 52 and the first driven wheel 531 can also be selectively gears adapted to each other, and the driving wheel 52 is in meshing driving connection with the first driven wheel 531.

[0100] As some preferred embodiments of the present application, as shown in the figures, Figure 1.1 , Figure 2 , Figure 2.1 , Figure 3、 Figure 3.1 and Figure 7 The first transmission shaft 53 and the second transmission shaft 54 are respectively installed on the upper surface of the bearing support 222 through bearing seats, and are respectively located on opposite sides of the first mounting seat 21 and parallel to each other.

The second driven wheel 532 and the fifth driven wheel 541 are in the same vertical plane, and the second driven wheel 532 is drivingly connected through the annular chain. Then, under the drive of the second drive unit 51, the first transmission shaft 53 and the second transmission shaft 54 can be driven to rotate synchronously, and the driven wheels arranged thereon can also be driven to rotate, and then the second mounting frame 3 can be driven through the non-annular chain.

[0101] Based on the above scheme, under the drive of the second drive unit 51, the scissor-type push-pull assembly can be quickly lifted through the chain wheel and chain transmission mode, and the working efficiency of the demolding overturning device 10 can also be indirectly improved. In addition, by adopting the above chain wheel and chain transmission mode, the third driven wheel 533, the fourth driven wheel 534, the sixth driven wheel 542 and the seventh driven wheel 543 have better synchronicity, and the lifting function and position accuracy of the second mounting frame 3 are better realized, so as to realize the automatic operation of the demolding overturning device 10.

[0102] As some preferred implementation forms of the foregoing embodiments, in order to achieve better transmission effect, the lower part of the bearing support 222 is further provided with a first shaft 55 which is parallel to the first transmission shaft 53 and located below the first transmission shaft 53. The eighth driven wheel 551 and the ninth driven wheel 552 which are both chain wheels are installed on the first shaft 55.

As shown in Figure 7.1 and Figures 1 to 7 The third driven wheel 533 and the eighth driven wheel 551 are in the same vertical plane, and the fourth driven wheel 534 and the ninth driven wheel 552 are also in the same vertical plane. The third driven wheel 533 and the eighth driven wheel 551 are drivingly connected through a non-annular chain, and the fourth driven wheel 534 and the ninth driven wheel 552 are drivingly connected through another non-annular chain (not shown in the figure).

[0103] Similarly, to achieve better transmission performance, a second shaft 56 is provided at the lower part of the support bracket 222. The second shaft 56 is parallel to and located below the second drive shaft 54. A tenth driven wheel 561 and an eleventh driven wheel 562, both sprockets, are mounted on the second shaft 56. The tenth driven wheel 561 is located above the connection point between the third non-circular chain and the second mounting bracket 3 and below the sixth driven wheel 542; the sixth driven wheel 542 is driveably connected to the tenth driven wheel 561 via the third non-circular chain. The eleventh driven wheel 562 is located above the connection point between the fourth non-circular chain and the second mounting bracket 3 and below the seventh driven wheel 543; the seventh driven wheel 543 is driveably connected to the eleventh driven wheel 562 via the fourth non-circular chain. In specific implementation, the sixth driven wheel 542 and the tenth driven wheel 561 are on the same vertical plane, and the seventh driven wheel 543 and the eleventh driven wheel 562 are also on the same vertical plane. The sixth driven wheel 542 and the tenth driven wheel 561 are connected by a non-circular chain drive, and the seventh driven wheel 543 and the eleventh driven wheel 562 are connected by a non-circular chain drive (not shown in the figure).

[0105] This application provides a first shaft 55 located below the first drive shaft 53, with two sprockets on the first shaft 55. A second shaft 56 located below the second drive shaft 54, with two sprockets on the second shaft 56, is also provided. By defining the positions of the sprockets on the first shaft 55 and the second shaft 56, the transmission of the non-circular chain can be better realized, thereby improving the reliability of the lifting transmission of the demolding flipping device 10.

As an alternative embodiment, the guide rod 91 can be selectively fixedly connected to one side of the support bracket 222, and the guide sleeve 92 can be fixedly connected to one side of the second mounting bracket 3.

[0107] The application can ensure the position accuracy of the demolding turnover device 10 during the pushing and pulling of the second mounting frame 3 by the lifting and pulling assembly 4 by setting the guide assembly 9 comprising the guide rod 91 and the guide sleeve 92. In addition, one of the guide sleeve 92 and the guide rod 91 is connected with the bearing support 222, and the other of the guide sleeve 92 and the guide rod 91 is connected with the second mounting frame 3, so that the deformation caused by the inertial force of the unit formed by the second mounting seat 22, the lifting and pulling assembly 4 and the second mounting frame 3 during rotation can be effectively alleviated under the action of the guide assembly 9; and the rigidity and stability between the bearing support 222 and the second mounting frame 3 are improved, so that the precision requirement of the demolding turnover device 10 can be better met.

[0131] In order to better meet the needs of automatic production of prefabricated parts, the application also provides a demolding equipment 100, which comprises a plurality of support columns 81, a first walking beam 82, a second walking beam 83, a demolding platform 20, and the demolding turnover device 10 involved in some of the foregoing embodiments.

[0132] It should be noted that the "demolding platform" of the application is not specifically limited, and it can be any platform that can meet the demolding requirements of prefabricated parts. Specifically, it can be selectively set according to the products to be produced.

[0133] The application also provides a prefabricated part production line, which comprises the demolding device 100 and the first transfer line 501 and the second transfer line 502 according to some of the above-mentioned embodiments or examples. Specifically, as shown in Figure 9 The first transfer line 501 extends from the previous work station to the position directly below the running track of the turnover device 10 for demolding, and the first transfer line 501 is configured to transfer the mold or the prefabricated part that has not been demolded to the working area of the turnover device 10 for demolding; and the second transfer line 502 extends from the working area of the turnover device 10 for demolding to the next work station. It should be pointed out that the previous work station can be a prefabricated part curing station or a turnover demolding station for small prefabricated parts.

[0134] In specific work, the first transfer line 501 can transfer the prefabricated part that has not been demolded to the working area of the demolding device 100. By controlling the demolding device 100, the prefabricated part that has not been demolded can be obtained from the first transfer line 501, and the prefabricated part that has not been demolded can be placed on the demolding platform 20 after being turned over by the demolding device 100, so as to realize the demolding of the prefabricated part by the demolding platform 20. After the demolding is completed, the mold is obtained from the demolding platform 20 and turned over by the demolding device 100, and the demolded mold is further transferred to the second transfer line 502. Further, under the transfer of the second transfer line 502, the demolded mold is transferred to the next work station of the production line.

[0135] When the production line is a composite prefabricated part production line, i.e., the production line can produce prefabricated parts of different categories, the demolding device 100 can be selectively used only to transfer the mold. Specifically, as shown in Figure 9 The production line comprises the first transfer line 501, the second transfer line 502, the demolding device 100, the small prefabricated part turnover demolding device 301 and the demolding device 100. The first transfer line 501 extends from the small prefabricated part turnover demolding device 301 to the working area of the turnover device 10 for demolding included in the demolding device 100. The second transfer line 502 extends from the working area of the turnover device 10 for demolding to the next work station.

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

[0137] When the product produced by the composite preform production line is a small preform, a plurality of small preform molds are fixed on the mold table, and the small preform fixed on the mold table is 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. Further, the mold table carrying the mold is 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, a mold cleaning station) by the second transfer line 502. That is, when the product produced by the production line is a small preform, the demolding device 100 only plays a transfer function for the mold. Then, as shown in the figure, the production line further includes a small preform stacking station 302, and the small preform flipping and demolding device 301 is connected to the small preform stacking station 302 through the small preform transfer line 504; in specific work, the preform demolded by the small preform flipping and demolding device 301 is transferred to the small preform stacking station 302 through the small preform transfer line 504. Figure 9

[0138] When the product produced by the composite preform production line is a sleeper, the undemolded sleeper is transferred to the working area of the demolding flipping device 10 through the first transfer line 501. Further, the undemolded sleeper is obtained from the first transfer line 501 by the demolding flipping device 10, and after the undemolded sleeper is flipped, it is placed on the demolding platform 20. Further, the sleeper is demolded by the demolding platform 20. After demolding is completed, the sleeper mold is obtained and flipped by the demolding flipping device 10, and the sleeper mold is transferred to the second transfer line 502. The second transfer line 502 transfers the sleeper mold to the next station (for example, a mold cleaning station).

[0139] It should be pointed out that the sequence of the demolding flipping device 10 in realizing the functions of flipping and transferring is not specifically limited, and in specific implementation, flipping can be selectively performed first, and then transferring is performed; or, transferring can be selectively performed first, and then flipping is performed; or, flipping can be selectively performed in the process of transferring. In order to improve the production efficiency of the production line, preferably, the demolding flipping device 10 performs the flipping process in the process of transferring.

[0140] In specific implementation, the production line can also selectively include a sleeper detection station 401, a sleeper stacking station 402, and a third transfer line 503. Specifically, as shown in the figure, the sleeper detection station 401 is connected to the first transfer line 501 through the third transfer line 503, and the sleeper detection station 401 is connected to the sleeper stacking station 402 through the second transfer line 502. ​ ​As shown, the third transfer line 503 passes through the tie detection station 401 and extends to the tie stacking station 402 from the working area of the demolding turnover device 10. In a specific working process, the demolded tie is transferred to the tie detection station 401 through the third transfer line 503, and the detected tie is transferred to the tie stacking station 402 through the third transfer line 503 for stacking.

[0141] As the transformable embodiment, the production line can also be selectively made as a tie production line, which is different from the above-mentioned composite preform production line in that the production line does not include the small preform turnover demolding device 301, the small preform transfer line 504 and the small preform stacking station 302.

[0142] It should be further noted that, although the production of small preforms and ties is taken as an example for illustration, the present application is not limited to the above-mentioned preform products. In a specific implementation, the small preform is not specifically limited, and it can be a small preform used in the fields of transportation, construction, water conservancy and municipal administration, etc. For example, it can be a curbstone, a ditch cover plate, a tunnel cable, etc. used in the field of construction; it can also be a roadbed protection fence, a cover plate, a fence piece, a slope protection brick, a column, a building block, etc. used in the field of transportation; and it can also be a cover plate, a slope protection brick, etc. used in the field of water conservancy.

For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above-mentioned description.
