Description

Technical Field

[0001] This utility model relates to the field of precast component production technology, specifically to a shield holding device, a shield demolding and transfer equipment, and a precast component production line. Background Technology

[0002] Prefabricated construction boasts advantages such as high efficiency, high quality, and high reliability, overcoming various limitations of traditional construction methods. Therefore, it is becoming an important development direction for railway engineering construction. Prefabricated panels are crucial components in prefabricated high-speed railway construction, with substantial demand and suitability for mass production and automation.

[0003] During the production of the shielding panels, processes such as hoisting and demolding are required after curing. Specifically, after centralized curing, the shielding panels need to be demolded. Because the curing panels are not yet sufficiently hard, traditional hoisting methods easily lead to cracks and deformation of the reinforcing bars, affecting the pass rate and proper installation. The main reason is the lack of suitable hoisting equipment. During hoisting and demolding, the panels are lifted manually using diagonal ropes connecting both ends, which easily damages the connection between the exposed reinforcing bars and the concrete structure. Furthermore, existing transfer methods suffer from low efficiency and high labor intensity for workers, severely hindering the implementation of automated shielding panel production.

[0004] Furthermore, in the actual production process of masking panels, considering factors such as the type, size, and production technology of the masks, technicians found that installing at least two masking molds side by side on the same mold table can effectively improve the production efficiency of the masks (for example, it can achieve efficient material distribution and facilitate masking panel curing, stacking, and transfer), and can especially better meet the needs of automated masking panel production. Developing a masking panel holding device, a masking panel demolding and transfer equipment, and a prefabrication production line that can better meet the needs of masking panel transfer would be of great significance. Utility Model Content

[0005] The purpose of this application is at least to provide a mask holding device that can meet the needs of mask transfer and holding, especially the needs of automated lifting and transfer of masks, so as to better solve the problems of mask transfer and demolding holding. Specifically, this is achieved through the following solution:

[0006] In a first aspect, this application provides a shield holding device, including a first mounting base, a first fork, a second fork, a first push-pull assembly, and a second push-pull assembly. The first fork and the second fork are opposite to each other and are both movably connected to the first mounting base. The first push-pull assembly is mounted on the first mounting base, and the push-pull end of the first push-pull assembly faces the first fork and is connected to the first fork. The second push-pull assembly is mounted on the first mounting base, and the push-pull end of the second push-pull assembly faces the second fork and is connected to the second fork.

[0007] The first fork holder and the second fork holder have a first state of being close to each other and a second state of being far apart. In the first state, the first fork holder is in a position that can overlap the exposed reinforcing bar at the first end of the cover plate, and the second fork holder is in a position that can overlap the exposed reinforcing bar at the second end of the cover plate. In the second state, both the first fork holder and the second fork holder are in a position where the cover plate is released.

[0008] This application, by setting up a first fork and a second fork, and adjusting the distance between the first and second fork, can hold and release the cover plate to meet the holding and releasing needs during the transfer process. Secondly, when hoisting the cover plate, the cover plate holding and releasing device of this application ensures that the exposed reinforcing bars are subjected to vertical upward force, effectively reducing the impact of local stress between the exposed reinforcing bars and the precast structure on the product qualification rate. Thirdly, by making the distance between the first and second fork adjustable, this application allows the cover plate holding and releasing device to meet the holding and releasing needs of cover plates of different lengths; and under the action of the first and second fork, reliable constraints can be applied to the cover plate, preventing it from falling off during transfer, making the transfer of the cover plate safer and more reliable. The cover plate holding and releasing device of this application can adjust the distance between the first and second fork by controlling the first and second push-pull components, thereby enabling the cover plate holding and releasing device to meet the needs of automated transfer.

[0045] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0046] Although terms such as "first," "second," and "third" may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these technical terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as a first element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

Therefore, the example term "below" can include both upper and lower orientations.

[0048] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "provided with," "connected," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] In this application, "above a certain number" includes the number itself; for example, "two or more" includes two.

[0051] 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.

[0052] The following is combined with Figures 1 to 9 This invention introduces the mask holding device 3, the mask demolding and transfer equipment 10, and the precast component production line provided by this utility model.

[0053] The cover holding device 3 of this application includes a first mounting base 33, a first fork holder 31, a second fork holder 32, a first push-pull assembly 361, and a second push-pull assembly 362. The first fork holder 31 and the second fork holder 32 are opposite to each other and both are movably connected to the first mounting base 33. The first push-pull assembly 361 is mounted on the first mounting base 33, and its push-pull end faces and is connected to the first fork holder 31. The second push-pull assembly 362 is also mounted on the first mounting base 33, and its push-pull end faces and is connected to the second fork holder 32. Under the action of the first fork holder 31 and the second fork holder 32, the cover holding device 3 of this application can reliably constrain the cover 100, preventing the cover 100 from falling off during transport, making the transport of the cover 100 safer and more reliable.

[0054] It should be noted that the structure of the first and second fork holders in this application is not specifically limited; they can be structural components that cooperate with each other to hold and place the cover plate 100. Specifically, as shown below... Figures 1 to 5 As shown, both the first fork holder 31 and the second fork holder 32 are L-shaped structures. In specific implementations, the first fork holder 31 and the second fork holder 32 are arranged in a first state where they are close to each other and a second state where they are far apart.

[0055] In practical operation, when in the first state, the first fork holder 31 is positioned to overlap the exposed reinforcing bar 101 at the first end of the cover plate 100, and the second fork holder 32 is positioned to overlap the exposed reinforcing bar 101 at the second end of the cover plate 100. When in the second state, both the first fork holder 31 and the second fork holder 32 are in the position where the cover plate 100 is released. When the cover plate 100 is lifted, the cover plate holding and releasing device 3 of this application causes the exposed reinforcing bar 101 to be subjected to vertical upward force, which can effectively reduce the local stress between the exposed reinforcing bar 101 and the precast body 102, and reduce the impact of the cover plate 100 on the product qualification rate during the transfer process.

[0056] In practical operation, the first push-pull assembly 361 and the second push-pull assembly 362 can be controlled to place the first fork holder 31 and the second fork holder 32 in a first state capable of holding the cover 100 or in a second state releasing the cover 100. This application, by setting the first fork holder 31 and the second fork holder 32 and adjusting the distance between them, can hold and release the cover 100 to meet the holding and placement needs of the cover 100 during transport. Furthermore, by making the distance between the first fork holder 31 and the second fork holder 32 adjustable, this application allows the cover holding and placement device 3 to meet the holding and placement needs of covers of different lengths.

[0057] It should also be noted that the "shield" in this application refers to a type of prefabricated component used in high-speed railway construction. It comes in various sizes and models. Specifically, as shown... Figure 9 The shield 100 shown includes a precast body 102 and a plurality of spaced-apart exposed steel bars 101. It should be noted that although the shield 100 has various sizes and models, they all include a precast body 102 with a similar structure and a plurality of spaced-apart exposed steel bars 101.

[0058] Specifically, such as Figure 2 and Figure 5 As shown, both the first push-pull assembly 361 and the second push-pull assembly 362 are telescopic cylinders. In operation, the telescopic cylinders are controlled to hold and release the cover. Specifically, a control unit controls the telescopic cylinders to automate the states of the first fork holder 31 and the second fork holder 32. The control unit can be optionally a PLC programmable controller, an industrial computer, etc. To better automate the transfer of the cover, relevant information can be collected by sensors as needed.

[0059] As an alternative implementation, the first push-pull assembly 361 and the second push-pull assembly 362 can be selectively both ball screw linear drive modules; or, selectively, the first push-pull assembly 361 and the second push-pull assembly 362 can be selectively both rack and pinion linear drive modules. The cover holding device 3 of this application can adjust the distance between the first fork holder 31 and the second fork holder 32 by controlling the first push-pull assembly 361 and the second push-pull assembly 362, thereby enabling the cover holding device 3 to meet the needs of automated transfer.

[0060] In some preferred embodiments of this application, the cover holding device 3 includes a first guide rail 341, a second mounting base 342, a second guide rail 351, and a third mounting base 352. The first guide rail 341 is mounted on the first mounting base 33 and extends toward the side where the second fork holder 32 is located; the second mounting base 342 is slidably adapted to the first guide rail 341, and the first fork holder 31 is mounted on the second mounting base 342. The second guide rail 351 is mounted on the first mounting base 33 and extends toward the side where the first fork holder 31 is located; the third mounting base 352 is slidably adapted to the second guide rail 351, and the second fork holder 32 is mounted on the third mounting base 352.

[0061] This application constrains the second mounting base 342 with the first guide rail 341 and the third mounting base 352 with the second guide rail 351, thereby better ensuring the positional accuracy of the second mounting base 342 and the third mounting base 352, so that the cover holding device 3 can better meet the needs of automated operation.

[0062] As some preferred embodiments of the foregoing implementation methods, such as Figure 1 and Figure 2 As shown, the first mounting base 33 is a long, narrow frame structure. Two parallel first guide rails 341 are provided at the upper part of the first end of the first mounting base 33. A second mounting base 342 is provided with a first slider that matches the first guide rails 341, and the second mounting base 342 is slidably connected to the first guide rails 341 via multiple first sliders. Two parallel second guide rails 351 are provided at the upper part of the second end of the first mounting base 33. A third mounting base 352 is provided with a second slider that matches the second guide rails 351, and the third mounting base 352 is slidably connected to the second guide rails 351 via multiple second sliders.

[0063] In order to better hold and place the cover, such as Figures 1 to 5 As shown, the first fork holder 31 includes a first lever arm 311 and a second lever arm 312. The first lever arm 311 is connected to the second mounting base 342 and extends vertically downward. The second lever arm 312 is connected to the extension end of the first lever arm 311 and extends horizontally toward the second fork holder 32, forming an L-shaped fork holder. The second fork holder 32 includes a third lever arm 321 and a fourth lever arm 322. The third lever arm 321 is connected to the third mounting base 352 and extends vertically downward. The fourth lever arm 322 is connected to the extension end of the third lever arm 321 and extends horizontally toward the first fork holder 31. In actual operation, when in the first state, the second lever arm 312 overlaps with at least one exposed reinforcing bar 101 at one end of the cover plate 100, and the fourth lever arm 322 overlaps with at least one exposed reinforcing bar 101 at the other end of the cover plate 100 to hold the cover plate 100.

[0064] To enable the cover holding device 3 to meet the requirements of automated operation, the first push-pull assembly 361 and the second push-pull assembly 362 can be selectively both telescopic cylinders (e.g., pneumatic telescopic cylinders, hydraulic telescopic cylinders, or electric cylinders). As an alternative implementation, the first push-pull assembly 361 and the second push-pull assembly 362 can also be selectively both ball screw linear drive modules; or selectively both gear and rack linear drive modules. It should be noted that the first push-pull assembly 361 and the second push-pull assembly 362 of this application are not limited to the push-pull assemblies listed above; they can also be other components capable of pushing and pulling the fork holder, such as linear drive motors, crank-connecting rod mechanisms, etc.

[0065] like Figures 3 to 7 The mask demolding and transfer device 10 shown includes a walking unit 2, a mounting base 41, a lifting and pushing assembly 43, and a mask holding device 3 as described in any of the aforementioned embodiments. Specifically, as follows... Figures 3 to 5As shown, the walking unit 2 includes an end beam 23, a crossbeam 22, and a walking drive unit 24. Each end of the crossbeam 22 is connected to an end beam 23, and the walking drive unit 24 is configured to drive the walking unit 2 to move. A mounting base 41 is connected to the crossbeam 22 and can move along the extension direction of the crossbeam 22; a lifting and pushing assembly 43 is vertically mounted on the mounting base 41, with the pushing and pulling end of the lifting and pushing assembly 43 facing downwards, and a cover plate holding device 3 is connected to the pushing and pulling end of the lifting and pushing assembly 43.

[0066] This application enables the mounting base 41 to travel along the extension direction of the crossbeam 22, thereby enabling the masking plate demolding and transfer equipment 10 to meet the demolding and hoisting needs of an efficient production mode in which at least two masking plate molds are installed side by side on the same mold table.

[0067] It should be noted that the lifting and pushing assembly in this application is not specifically limited; it can be any assembly capable of driving the cover holding assembly to rise and fall vertically. In specific implementations, the lifting and pushing assembly 43 can be selectively configured as a telescopic cylinder (pneumatic telescopic cylinder, hydraulic telescopic cylinder, or electric cylinder), a screw lifting platform, a gear and chain driven lifting assembly, etc. Specifically, as shown... Figures 3 to 5 As shown, the lifting and pushing assembly 43 is a telescopic cylinder, and two telescopic cylinders are vertically spaced on the mounting base 41.

[0068] like Figures 3 to 5 As shown, the demolding and transfer equipment 10 also includes a load-bearing truss, which comprises two load-bearing beams 1, each supported by two support columns 11. The traveling unit 2 is connected to the load-bearing beams 1 via end beams 23. The traveling unit 2 is capable of moving on the load-bearing truss.

[0069] It should also be noted that the walking drive unit in this application is not specifically limited; it can be any unit capable of bridging the supporting beam 1 and moving along the supporting beam 1. In specific implementation, such as... Figures 1 to 5 As shown, a track extending along the length of the supporting beam 1 is provided on the supporting beam 1, and two sets of traveling wheels adapted to the track are respectively provided on each end beam 23. At least one set of traveling wheels is further connected to a traveling drive unit 24. The traveling drive unit 24 includes a motor, and the motor is controlled by a control unit. In actual operation, the position of the traveling unit 2 on the supporting beam 1 is adjusted by controlling the motor.

[0070] As an alternative implementation, the end beam 23 may be optionally equipped with a slider that slides to adapt to the track on the bearing beam 1, and the end beam 23 is slidably connected to the bearing beam 1 via the slider. Furthermore, the travel drive unit 24 may be a unit including a motor and a linear transmission module. For example, the travel drive unit 24 may be a drive unit including a motor, transmission gears, and a transmission rack; or the travel drive unit 24 may be a drive unit including a motor and a ball screw.

[0071] This application connects the mask holding device 3 to the mounting base 41 via the lifting and pushing assembly 43, thereby enabling the vertical adjustment of the mask holding device 3 and allowing the mask demolding and transfer equipment 10 to demold the mask. Furthermore, the height adjustment function of the lifting and pushing assembly 43 allows for adaptation to different mask models, meeting the demolding requirements of various mask models. Secondly, this application includes a walking unit 2 in the mask demolding and transfer equipment 10, and connects the mask holding device 3 to the walking unit 2 via the mounting base 41, thereby enabling the mask demolding and transfer equipment 10 to meet the transfer needs of the mask 100. Thirdly, this application achieves automated demolding and transfer functions of the mask 100 through the control of the walking drive unit 24, the lifting and pushing assembly 43, and the first and second pushing and pulling assemblies 361 and 362.

[0072] As some preferred embodiments of this application, for example Figures 3 to 5 As shown, the mask demolding and transfer device 10 also includes a fourth mounting base 42, which is located directly below the mounting base 41. The push-pull end of the lifting and pulling assembly 43 is connected to the fourth mounting base 42, and the first mounting base 33 is located directly below the fourth mounting base 42, with its middle portion connected to the fourth mounting base 42. As a possible implementation, in specific implementations of the technical solution of this application, the fourth mounting base 42 may not be provided, allowing the push-pull end of the lifting and pulling assembly 43 to be directly connected to the first mounting base 33.
