Description

Technical Field

[0001] The invention relates to the technical field of prefabricated part production, and in particular to a composite prefabricated part production line and a prefabricated part production method. Background Art

[0002] In the fields of transportation, construction, water conservancy and municipal administration, there are many types of small prefabricated parts used in large quantities. Realizing the mass production, streamlining and high efficiency of prefabricated parts production has become the current and future development focus and direction.

[0003] In the existing production process of small preforms, due to the small structure of the preforms, in order to reduce the investment cost of equipment, the molds used are generally made of low-cost materials such as plastic. Specifically, multiple small preform molds are fixed on the mold table to facilitate the implementation of processes such as laying, transporting, and demoulding of small preforms, thereby better realizing the batch and automated production of small preforms and improving production efficiency.

[0004] Flip demoulding is an important process in the production of prefabricated parts. In the field of railway transportation, what needs to be produced is not only small prefabricated parts, but also bridge deck components with larger structures. However, the flip demoulding equipment for small prefabricated parts and the flip demoulding equipment for bridge deck components with larger structures often require flip demoulding equipment with different structures for flip demoulding. Moreover, in the prior art, small prefabricated parts and bridge deck components are produced through different production lines, which has the problems of large floor space, high production cost and overcapacity. The existing squirrel cage type small prefabricated part flip demoulding equipment obviously cannot meet the assembly line production requirements for the production of small prefabricated parts and bridge deck components at the same time. Therefore, it is of great significance to develop a small prefabricated part flip demoulding equipment that can meet the assembly line production requirements of small prefabricated parts and bridge deck components with larger structures at the same time. Summary of the invention

[0061] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] According to the following Figures 1 to 9 The composite prefabricated part production line and production method provided by the present invention are introduced.

[0063] The composite prefabricated component production line provided in the present application is used to produce bridge deck components and small prefabricated components. The composite prefabricated component production line includes a conveying line 91 , a flip demoulding device 200 and a small prefabricated component transfer line 92 .

[0064] Among them, the conveyor line 91 is configured to be able to transport bridge deck component molds and transport mold platforms carrying small prefabricated component molds. It should be pointed out that the "conveyor line" in this application is not specifically limited, and it can be any conveyor line that can transport mold platforms carrying undemolded prefabricated components. The conveyor line 91 should be selectively set according to actual needs so that the conveyor line 91 can meet production needs. In specific implementation, the conveyor line 91 can be selectively made into a roller conveyor line, a roller conveyor line, a traction conveyor line, or a conveyor line including a transfer trolley. As a preference, the conveyor line 91 is an automated conveyor line to realize the automated transportation process of the mold platform. In specific implementation, the mold of the bridge deck component transported by the conveyor line 91 can be a mold that has been demolded or a mold that has not been demolded. Similarly, the small prefabricated component mold transported by the conveyor line 91 can be a mold that has been demolded or a mold that has not been demolded.

[0065] The "small preform transfer line" in the present application is not specifically limited, and it can be any transfer line that can receive the small preforms removed by the flip demoulding device 200. In specific implementation, the small preform transfer line can be selectively a roller transfer line, a sprocket chain transfer line, or a belt transfer line, etc. In specific implementation, the small preform transfer line 92 is also preferably an automated transfer line. In order to better realize the automated production of small preforms.

[0066] The flip demoulding device 200 includes a carrier frame 1, a mold table holding device 2, a conveying device 3, a flipping drive device 5 and a jacking demoulding device 7. The mold table holding device 2 is installed on the carrier frame 1, and the conveying device 3 is connected to the carrier frame 1. The flipping drive device 5 is transmission-connected to the carrier frame 1, and the flipping drive device 5 is configured to drive the carrier frame 1 to flip so that the carrier frame 1 has a first position and a second position flipped toward one side. The jacking demoulding device 7 is configured to lift the mold table 100 located at the second position, and the jacking demoulding device 7 is located on one side of the conveyor line 91, as shown in FIG. Figure 2 and Figure 3 As shown, the jacking and demoulding device 7 is located on one side of the flipping and demoulding equipment 200, the small preform transfer line 92 is located on one side of the jacking and demoulding device 7, and the small preform transfer line 92 is configured to receive and transfer the small preforms conveyed by the conveying device 3.

[0067] It should be noted that the "lifting and demoulding device" in the present application is not specifically limited, and it can be any device that can lift the mold platform to facilitate the demoulding of the small preform. Figure 3 and Figure 5 As shown, the lifting and demoulding device 7 includes four groups of supporting columns 71, each group of supporting columns 71 can pass through the conveying device 3 to support the mold table flipped by the small preform flipping device. And each group of supporting columns 71 is correspondingly provided with a lifting rod 72, and the first end of the lifting rod 72 is configured to pass through the conveying device 3 to lift the mold table flipped by the small preform flipping device. The second end of the lifting rod 72 is connected to an inflatable bag 73.

[0068] During specific operation, the demoulding device 200 flips the mold platform carrying the undemolded mold to the second position, and multiple groups of support columns 71 support the flipped mold platform, and further inflate and deflate the airbag 73 to drive the lifting rod 72 to lift the mold platform, thereby vibrating the mold platform to achieve the demoulding effect. During specific implementation, the lifting and demoulding device 7 can also be a lifting and demoulding device including a crank connecting rod mechanism; or the lifting and demoulding device 7 can be selectively a lifting and demoulding device including a telescopic cylinder.

[0069] In a specific implementation process, when the carrier 1 is in the first position, the conveyor line 91 passes under the carrier 1. The conveyor 3 moves toward the conveyor line 91 (such as Figure 2 and Figure 3 ), and the mold table holding device 2 has a position to hold the mold table conveyed by the conveyor line 91. When the carrier 1 is in the second position, the mold table holding device 2 has a position to hold the mold table after demoulding. The conveying device 3 is located above the lifting and demoulding device 7 and below the carrier 1, so that the conveying device can receive and transfer the demoulded small preforms in the second position.

[0070] Specifically, Figure 1As shown, when the carrier 1 is in the first position, the conveyor line 91 passes under the carrier 1, so that the conveyor line 91 can transfer the mold table 100 carrying the un-demolded preforms to the flip demoulding device 200; it can also carry and transfer the demoulded mold table 100. In order to enable the small preform transfer line 92 to receive the demoulded small preforms, Figure 1 As shown, the small preform transfer line 92 is located on one side of the lifting and demoulding device 7, and the extension direction of the small preform transfer line 92 is parallel to the extension direction of the conveying line 91. The small preform transfer line 92 is located downstream of the conveying route of the conveying device 3 to receive the small preforms transferred by the conveying device 3. As a convertible embodiment, the small preform transfer line 92 can also be selectively made perpendicular to the conveying line 91.

[0071] Specifically, Figure 2 and Figure 3 As shown, the conveying device 3 is connected to the carrier 1 via the lifting drive device 4, so that the conveying device 3 can approach and move away from the mold platform placement area 10. The conveying direction of the conveying device 3 is perpendicular or substantially perpendicular to the push-pull direction of the lifting drive device 4, and when the carrier 1 is in the first position, the conveying device 3 can move toward and away from the conveyor line. And the flipping drive device 5 is transmission-connected to the carrier 1, and the flipping drive device 5 is configured to drive the carrier 1 to flip, so that the carrier 1 is in the first position or in the second position.

[0072] It should be noted that the flip demoulding device 200 of the present application may not be provided with the lifting drive device 4, and the specific setting can be selected according to production needs. However, it is preferred that the conveying device 3 is connected to the carrier 1 through the lifting drive device 4.

[0073] When the small preform needs to be flipped and demolded, the mold table holding device 2 holds the mold table 100 in the mold table placement area 10, and moves the conveying device 3 toward the mold table 100 to a set position through the lifting drive device 4, so as to limit and receive the demolded preform. The carrier 1 is further driven to flip toward one side to a set position through the flipping drive device 5 (preferably, the flipped mold table 100 is in a horizontal or substantially horizontal state). The mold table holding device 2 releases the flipped mold table 100 to a set position (for example, a position that can support the mold table 100); then, the mold table 100 is vibrated and demolded to vibrate the small preform onto the conveying device 3. The conveying device 3 transports the demolded preform to a set position (for example Figure 1 As shown, the conveying device 3 transfers the preform to the small preform transfer line 92). After demolding is completed, the demolded mold table 100 is further obtained by the mold table holding device 2, and then the demolded mold table 100 is flipped to the mold table placement area 10 by the flip driving device 5.

[0074] It should be noted that the "mold table placement area" in this application refers to the position where the mold table transferred by the conveyor line is located so that the mold table holding device can pick it up. Figure 6 shown.

[0075] It should be noted that the "carrier" mentioned in this application is not specifically limited, and it can be any structure that meets the installation requirements of the carrier and conveyor device 3. The carrier 1 can be selectively made of profiles (such as square steel pipes, channel steels, etc.). Figures 2 to 7 The supporting frame 1 shown is welded from square steel pipes, channel steels and the like.

[0076] It should also be noted that the "transfer device" in the present application is not specifically limited, and it can be any conveying device that can receive the small preforms after demoulding and can transfer the received small preforms to a set position. In specific implementation, the conveying device 3 can be selectively a conveying device including a plurality of conveying rollers 32 (such as Figure 2 and Figure 3 The conveying device 3 may also be a chain conveying device (such as Fig. 9 The conveyor 3 may be a belt conveyor (not shown in the figure). In the specific implementation, it is preferred that the conveyor components of the conveyor 3 are on the same plane as a whole, and can cover the mold fixed on the mold table 100, so that the demolded preforms can be better received during the flipping and demolding process. The present application provides a conveyor 3, which can assist in the flipping and demolding of small preforms under the action of the conveyor 3; specifically, during the flipping of the mold table 100, the conveyor 3 can limit and receive the small preforms to prevent the small preforms from falling during the flipping process, thereby avoiding the problem of damage to the preforms.

[0077] In addition, the present application connects the conveyor 3 to the carrier 1 through the lifting drive device 4, thereby adjusting the distance between the conveyor 3 and the mold table 100. In the specific production process, the distance between the conveyor 3 and the mold table 100 held by the mold table holding device 2 can be adjusted according to the production needs of small preforms of different sizes, specifications and types, so that the conveyor 3 is located in a position where it can better receive the small preforms.

[0078] It should also be pointed out that the "lifting drive device" in the present application is not specifically limited, and it can be any drive device that can meet production needs and can drive the conveying device 3 to move toward or away from the mold table placement area 10 to a set position.

[0111] The carrier frame 1 is located at a first position;

[0112] The lifting drive device 4 drives the conveying device 3 to move a set distance toward the mold table placed in the mold table placement area 10;

[0113] The mold stage 100 placed in the mold stage placement area 10 is held by the mold stage holding device 2;

[0121] In specific implementation, the support frame 1 is located at the first position or the second position by means of the flip drive device 5. Specifically, according to the needs of the production process, the flip drive device 5 is controlled to make the support frame 1 located at the first position or the second position.

[0122] There is no specific limitation on the distance set by which the lifting drive device 4 drives the conveyor device 3 to move toward the mold table placement area 10, and it can be selectively set according to the size of the small preforms to be produced, so as to reduce the distance between the mold on the mold table and the conveyor device 3 as much as possible without affecting the demoulding process, so as to achieve the purpose of reducing the falling height of the small preforms when demoulding.

[0123] When the production line is producing larger bridge deck components, in order to prevent the flip demoulding device 200 from affecting normal production, the carrier 1 should be located in the second position so that the conveyor line 91 can meet the conveying needs of the production of larger prefabricated parts.
