Description

Technical Field

[0002] Prefabricated construction offers advantages such as high efficiency, high quality, and excellent reliability. It circumvents the limitations of traditional construction methods and is therefore becoming a key development direction in railway engineering. Shields are a key prefabricated component in prefabricated high-speed railway construction. They are diverse, in high demand, and suitable for mass production.

[0003] During the production process, the cured panels require lifting and demolding. Specifically, after centralized curing, the panels need to be demolded. Because the panels are not yet sufficiently hard after curing, traditional lifting methods can easily lead to cracks and deformation of the steel bars, affecting the panel's pass rate and proper installation. Furthermore, existing transport and demolding methods also suffer from low efficiency and high labor intensity.

[0004] In the actual production process of blinds, considering factors such as the type, size, and production process of the blinds, technicians have discovered that installing at least two blind molds side by side on the same mold base can effectively improve blind production efficiency (for example, it can achieve efficient material distribution and facilitate blind maintenance, stacking, and transportation), especially better meeting the needs of automated blind production. To solve the above-mentioned problems existing in the existing technology, it is necessary to develop a device that can demold and transport the blinds in this type of blind production model.

[0048] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] The following is based on Figures 1 to 7 The present invention introduces the shield demoulding and transfer equipment and the prefabricated parts production line provided by the present invention.

[0050] The shield demoulding and transfer device 10 provided in this application includes a supporting beam 1, a traveling unit 2, and a shield holding device 3. Two supporting beams 1 are arranged side by side; the traveling unit 2 is connected across the supporting beams 1 and is configured to move along the supporting beams 1.

[0051] It should be pointed out that the "load-bearing beam" in this application is not specifically limited, and it can be any beam body that is arranged horizontally to meet the walking unit's walking needs. In specific implementation, it can be made of square steel pipes, I-beams and other profiles. Figure 1 and Figure 2 As shown, the load-bearing beam 1 is made of I-beam, and the two load-bearing beams 1 are supported by support columns 11 respectively, and the two load-bearing beams 1 are arranged side by side and horizontally.

[0052] It should also be noted that the "shroud" in this application is a type of prefabricated component used in high-speed railway construction. It has a variety of sizes and models. Figure 7 The shield 100 shown includes a prefabricated body 102 and a plurality of spaced apart exposed steel bars 101. It should be noted that although the shields come in a variety of sizes and models, they all include a prefabricated body 102 and a plurality of spaced apart exposed steel bars 101 of similar structure.

[0053] The "traveling unit" in this application is not specifically limited and can be any unit that can be connected across the load-bearing beam and can travel along the load-bearing beam. Figures 1 to 5 As shown, the travel unit 2 can optionally include a crossbeam 22 and an end beam 23. Two crossbeams 22 arranged side by side are each connected to an end beam 23 at each end. The crossbeams 22 are connected across the two supporting crossbeams 1 via the end beams 23. Furthermore, a track extending along the length of the supporting crossbeam 1 is provided on the supporting crossbeam 1, and each end beam 23 is provided with two travel wheel assemblies adapted to the track. Furthermore, at least one of the travel wheel assemblies is connected to a travel drive unit 24. The travel drive unit 24 includes an electric motor, which is controlled by a control unit. During operation, the position of the travel unit 2 on the supporting crossbeam 1 is adjusted by controlling the electric motor.

[0054] As an alternative embodiment, the end beam 23 can optionally be equipped with a slider that slidably engages with the track on the support beam 1. The end beam 23 can be slidably connected to the support beam 1 via the slider. Furthermore, the travel drive unit 24 can be a unit comprising a motor and a linear transmission module. For example, the travel drive unit 24 can include a motor, a transmission gear, and a transmission rack; or the travel drive unit 24 can include a motor and a ball screw.

[0055] In a specific implementation, the shield holding device 3 includes a mounting base 371, a lifting and pushing assembly 38, and a shield holding assembly. The mounting base 371 is connected to the crossbeam 22 and can move along the crossbeam 22. The lifting and pushing assembly 38 is vertically mounted on the mounting base 371, with the pushing end of the lifting and pushing assembly 38 facing downward. The shield holding assembly is connected to the pushing end of the lifting and pushing assembly 38.

[0056] It should be noted that the lifting and pushing assembly in this application is not specifically limited and can be any assembly that can drive the shield holding assembly to lift in the vertical direction. In specific implementation, the lifting and pushing assembly 38 can be selectively made into a telescopic cylinder (pneumatic telescopic cylinder, hydraulic telescopic cylinder or electric cylinder), a screw lifting platform, a gear chain transmission lifting assembly, etc. Figures 3 to 5 As shown, the lifting and pushing assembly 38 is a telescopic cylinder, and two telescopic cylinders are vertically installed at intervals on the mounting base 371.

[0057] The present application provides a lifting and pushing assembly 38, which, under the action of the lifting and pushing assembly 38, can adjust the vertical position of the shield holding assembly, thereby adjusting the vertical positions of the first fork holding member 31 and the second fork holding member 32, thereby better meeting the transportation needs of shields 100 of different models and sizes. In addition, the provision of the lifting and pushing assembly 38 can also enable the shield demolding and transfer device 10 to meet the requirements of demolding the shield 100, thereby providing the shield demolding and transfer device with a demolding function.

[0058] Specifically, the shield holding assembly includes a first fork holding member 31 and a second fork holding member 32 that are opposite to each other. The first fork holding member 31 and the second fork holding member 32 are located below the traveling unit 2. The insertion portion of the first fork holding member 31 extends toward the insertion portion of the second fork holding member 32, and the insertion portion of the second fork holding member 32 extends toward the first fork holding member 31.

[0059] It should be pointed out that the first fork holder 31 and the second fork holder 32 in the present application can be adapted to the exposed steel bars 101 on the shield 100, and the extension lengths of the inserting portions of the first fork holder 31 and the second fork holder 32 are not specifically limited, and can be selectively set according to the position of the ends of the exposed steel bars 101 on the shield 100.

[0060] The first fork holding member 31 and the second fork holding member 32 have a first state in which they are close to each other and a second state in which they are separated. In the first state, the first fork holding member 31 is in a position where it can overlap the exposed steel bars 101 at the first end of the shield 100, and the second fork holding member 32 is in a position where it can overlap the exposed steel bars 101 at the second end of the shield 100, so as to achieve the holding of the shield; in the second state, the shield holding device 3 is in a position to release the shield 100. When the shield 100 is hoisted, the shield holding device 3 of the present application causes the exposed steel bars 101 to be vertically upwardly stressed, which can effectively reduce the local stress between the exposed steel bars 101 and the prefabricated body 102, and reduce the impact of the shield 100 on the product qualification rate during transportation.

[0061] By enabling the first and second fork holders 31 and 32 to have a first, close-together state and a second, separated state, and enabling the travel unit 2 to travel along the support beam 1, the present invention further improves the forking and transporting of the shield 100, thereby satisfying the shield 100's transport function. Secondly, by connecting the shield holding assembly to the lifting and pushing assembly 38, the height position of the shield holding assembly can be adjusted under the action of the lifting and pushing assembly 38, enabling the shield demolding and transporting device 10 to function as a shield demolding device and better meet the transport needs of shields of different models and sizes. Thirdly, the present invention makes the distance between the first and second fork holders 31 and 32 adjustable, thereby meeting the demolding and transport needs of shields 100 of different lengths. The coordinated forking action of the first and second fork holders 31 and 32 further ensures the reliable restraint of the shield 100, preventing it from falling off and ensuring safer and more reliable transport of the shield 100. In addition to the above effects, the shield demoulding and transferring equipment 10 defined in the present application can also meet the requirements of automatic demoulding and transferring of the shield 100 .

[0062] In addition, the shutter demoulding and transfer equipment claimed in the present application can better meet the shutter demoulding and lifting needs of the production mode in which multiple shutter molds are provided on the mold table, thereby indirectly improving the production efficiency of the shutter.

[0063] As some preferred embodiments of the present application, the shield holding assembly includes a first mounting seat 33. Figure 3 、 Figure 4 and Figure 5 As shown, the first mounting seat 33 is connected to the mounting base 371 and is located below the mounting base 371. The first fork holding member 31 is installed below the first end of the first mounting seat 33 and is configured to move toward and away from the second fork holding member 32. The second fork holding member 32 is installed below the second end of the first mounting seat 33 and is configured to move toward and away from the first fork holding member 31.

[0064] It should be noted that the structure of the first mounting base in this application is not specifically limited, and it can be any structure that meets the installation requirements of the first fork holder and the second fork holder. Figure 3 、 Figure 4 and Figure 5 As shown, the first mounting seat 33 is an elongated square frame structure as a whole.

[0065] As some preferred embodiments of the present application, the shield holding device 3 includes a first guide rail 341, a second mounting seat 342, a second guide rail 351, a third mounting seat 352, and a mounting seat driving unit. The mounting seat driving unit is configured to drive the second mounting seat 342 and the third mounting seat 352 to move toward or away from each other.

[0066] Then by Figure 3 、 Figure 4 and Figure 5 As shown, a first guide rail 341 is mounted at the first end of the first mounting seat 33 and extends horizontally toward the second end of the first mounting seat 33. A second mounting seat 342 is connected to the first guide rail 341 and is configured to move along the first guide rail 341. Specifically, two parallel first guide rails 341 are provided on the upper surface of one end of the first mounting seat 33. The first mounting seat 33 is provided with a plurality of sliders that respectively adapt to the two first guide rails 341, so that the second mounting seat 342 can drive the first fork holder 31 to move along the first guide rails 341.

[0067] Then by Figure 3 、 Figure 4 and Figure 5 As shown, a second guide rail 351 is mounted at the second end of the first mounting seat 33 and extends horizontally toward the first end of the second mounting seat 342. A third mounting seat 352 is connected to the second guide rail 351 and is configured to move along the second guide rail 351. Specifically, two parallel second guide rails 351 are provided on the upper surface of the other end of the first mounting seat 33. The third mounting seat 352 is provided with a plurality of sliders that respectively match the two second guide rails 351, so that the third mounting seat 352 can drive the second fork holder 32 to move along the second guide rails 351.

[0068] It should be noted that the "mounting base drive unit" in this application is not specifically limited and can be any unit capable of driving the first fork holding member 31 and the second fork holding member 32. In a specific implementation, the mounting base drive unit can selectively include one drive assembly or two drive assemblies, i.e., the first fork holding member 31 and the second fork holding member 32 are driven by the same drive assembly, or the first fork holding member 31 and the second fork holding member 32 are driven by different drive assemblies.

[0069] In an embodiment driven by the same drive assembly, the mounting base drive unit can optionally include a drive motor, a rocker arm, a first connecting rod, and a second connecting rod, wherein the middle portion of the rocker arm is transmission-connected to the power output end of the drive motor, one end of the first connecting rod is hingedly connected to one end of the rocker arm, and the other end of the first connecting rod is hingedly connected to the second mounting base 342; one end of the second connecting rod is hingedly connected to the second end of the rocker arm, and the other end of the second connecting rod is hingedly connected to the third mounting base 352. When the drive motor drives the rocker arm to rotate, the first connecting rod drives the first fork holder 31, while the second connecting rod drives the second fork holder 32 to move, so that the first fork holder 31 and the second fork holder 32 are in the first state or the second state.

[0070] In an embodiment in which different drive assemblies are used, the mounting base drive unit can optionally include two push-pull assemblies, with the second mounting base 342 connected to one push-pull assembly and the third mounting base 352 connected to the other push-pull assembly. During operation, the first fork holding member 31 and the second fork holding member 32 are placed in the first state or the second state by controlling the two push-pull assemblies.

[0071] This application ensures the position accuracy of the second mounting seat 342 and the third mounting seat 352 by constraining the first guide rail 341 to the second mounting seat 342 and by constraining the second guide rail 351 to the third mounting seat 352, so that the shield holding device 3 can better meet the needs of automated operation.

[0072] As some preferred embodiments of the present application, the first fork holding member 31 preferably includes a first force arm 311 and a second force arm 312. Figure 3 、 Figure 4 and Figure 5 As shown, the first lever arm 311 is connected to the second mounting seat 342 and extends vertically downward, the second lever arm 312 is connected to the extended end of the first lever arm 311 and extends horizontally toward the second fork holding member 32. The second fork holding member 32 includes a third lever arm 321 and a fourth lever arm 322. The third lever arm 321 is connected to the third mounting seat 352 and extends vertically downward, the fourth lever arm 322 is connected to the extended end of the third lever arm 321 and extends horizontally toward the first fork holding member 31.

[0073] It should be noted that the dimensions of the first and second lever arms 311, 312 of the first fork holder 31, and the dimensions of the third and fourth lever arms 321, 322 of the second fork holder 32 should be selectively set as needed. It should also be noted that the cross-section of the second and fourth lever arms 312, 322 perpendicular to their extension direction should be smaller than the area enclosed by the exposed steel bars 101 of the shield 100, so that the first and second fork holders 31, 32 can be smoothly inserted into the area enclosed by the exposed steel bars 101.

[0074] As an example under some of the aforementioned embodiments, the mounting seat driving unit includes a first push-pull component 361 and a second push-pull component 362. The first push-pull component 361 is horizontally mounted on the first mounting seat 33.
