Description

Technical Field

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

[0002] In some fields, such as construction, transportation, and water conservancy, there are many types of prefabricated components and the demand is large. The existing prefabricated component production lines are highly targeted and it is difficult to meet the production needs of prefabricated components with large differences at the same time. For example, in the railway field, especially when laying high-speed railways, a large number of sleepers (especially double-block sleepers) and small prefabricated components are required. The small prefabricated components required are not only large in number, but also of many types; for example, roadbed protection fences, cover plates, fences, slope protection bricks, columns, etc.

[0003] Automation, batch production and flexibility of prefabricated components have become the future development trend. In the actual production process, different types of prefabricated component products often have different production processes, and the equipment for implementing the processes cannot be well adapted. Different production lines are often used for production, resulting in large space occupied by the production line, high production input costs, low production line utilization, and high production costs.

[0004] In the actual production process of prefabricated components, the required production processes vary greatly depending on the structure. For example, the actual production process of double-block sleepers requires mold cleaning, mold release spraying, sleeve spiral reinforcement assembly mold placement, truss mold placement, material laying, vibration, maintenance and demoulding. In the actual production process of small prefabricated components, mold cleaning, mold release spraying, steel skeleton mold placement, material laying, vibration, maintenance and demoulding are required. Although double-block sleepers and small prefabricated components have the same process, due to the different sizes of sleepers and small prefabricated components, the molds required for production are different, resulting in different implementation methods for the same process. For example, for the same demoulding process, it has been proven in practice that the demoulding equipment for double-block sleepers is not suitable for demoulding of small prefabricated components, and the demoulding equipment for small prefabricated components is not suitable for demoulding of double-block sleepers.

[0005] There is no production line in the prior art that can simultaneously meet the production needs of sleepers and small prefabricated components. In summary, it would be of great significance if a production line that can meet the production needs of sleepers and small prefabricated components could be developed. Summary of the invention

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.

[0091] Combine the following Figures 1 to 8The composite prefabricated component production line provided by the present invention is introduced. The composite prefabricated component production line provided by the present application includes a material distribution station 1, a curing kiln 3, a flip demoulding device 4, a sleeper demoulding device 5, a mold cleaning station 6, a demoulding agent spraying station 7, a casing spiral rib installation station 8, a metal frame installation station 9, a first transfer line 21, a second transfer line 22, a third transfer line 23, a fourth transfer line 24, a fifth transfer line 25, a sixth transfer line 26, a seventh transfer line 27 and an eighth transfer line 28.

[0092] It should be noted that the composite prefabricated component production line involved in this application can also be called a flexible prefabricated component production line, which specifically means that the production line defined in this application can simultaneously meet the production needs of at least two prefabricated components with different production processes. The composite prefabricated component production line involved in this application especially meets the production needs of small prefabricated components and double-block sleepers.

[0093] It should also be noted that the material dispensing station 1 in the present application is a station set up to achieve material dispensing in the cavity of the mold. In specific implementation, a material dispensing machine for dispensing materials for different products can be configured at the material dispensing station 1 according to actual needs. The specific selection can be based on the material quantity of the product.

[0094] It should be pointed out that the small prefabricated components produced by the production line involved in this application can be any small prefabricated components used in the construction field, transportation field, water conservancy field, etc. For example, curbstones, ditch covers, tunnel cable covers, etc. used in the construction field; and roadbed protection fences, covers, fences, slope protection bricks, columns, masonry pieces, etc. used in the transportation field (specifically, such as high-speed railways, highways, municipal administration, etc.). Another example is the covers and slope protection bricks used in the water conservancy field.

[0095] Specific as Figure 1 and Figure 3 As shown, the material distributing station 1 is provided with a first material distributing device 11 and a second material distributing device 12 . The first material distributing device 11 is configured to distribute material to the sleeper mold carried by the first transfer line 21 , and the second material distributing device 12 is configured to supply material to the small prefabricated component mold carried by the first transfer line 21 .

[0096] It should be pointed out that the sleeper mold in the present application refers to the mold required for producing sleepers, and the small prefabricated component mold in the present application refers to the mold used for producing small prefabricated components.

[0097] It should also be pointed out that the first material distribution equipment 11 in the present application is not specifically limited, and it can be any material distribution equipment that can meet the material distribution requirements of sleeper production. Similarly, the second material distribution equipment 12 in the present application is not specifically limited, and it can be any material distribution equipment that can meet the material distribution requirements of small prefabricated component production. In specific implementation, the first material distribution equipment 11 and the second material distribution equipment 12 can be selectively fixed at the material distribution station 1 at intervals along the extension direction of the first transfer line 21.

[0098] When the material quantities of different prefabricated component products are similar, the same material distribution equipment can be selected for distribution. Preferably, the material distribution amount of the material distribution equipment is adjustable to better meet the distribution needs of different products with similar material quantities. For example, for small prefabricated components of different shapes, although the structures are different, the material quantities are similar, and the production needs of different prefabricated components can be better met by adjusting the material output of the material distribution equipment. In order to meet the distribution needs of different prefabricated components, it is further preferred that the material distribution machine includes multiple material distribution outlets, so that the material distribution equipment can distribute multiple products at a time, thereby improving the production efficiency of prefabricated components. For example, the number of material distribution outlets provided on the material distribution machine is one, two, three, four or more than five. Preferably, the position of at least part of the material distribution outlets is further made adjustable to meet the distribution adjustment requirements of small prefabricated components of different specifications.

[0099] As some preferred embodiments of the present application, at least one of the first material distribution equipment 11 and the second material distribution equipment 12 can be selectively moved along the extension direction of the first transfer line 21. Specifically, a guide rail is laid on the material distribution station 1, and the guide rail extends from the material distribution station 1 toward the curing kiln 3 to a set position to meet the position adjustment needs of the first material distribution equipment and / or the second material distribution equipment. As a convertible embodiment, the first material distribution equipment 11 and the second material distribution equipment 12 can be selectively suspended above the first transfer line 21, and at least one of the first material distribution equipment 11 and the second material distribution equipment 12 can be moved above the first transfer line 21 along the extension direction of the first transfer line 21.

[0100] As some preferred embodiments under the aforementioned implementation modes, the material distribution station 1 is further provided with a vibrating device 13, and the vibrating device 13 is configured to vibrate the mold after the material distribution. In specific implementation, it is preferred to set two vibrating devices 13 at the material distribution station 1, one of which is a strong vibrating device and the other is a weak vibrating device. Or both vibrating devices 13 are strong vibrating devices, thereby indirectly improving the production efficiency and product quality of the product while meeting the material distribution vibration requirements. When one of the two vibrating devices 13 is a strong vibrating device and the other is a weak vibrating device, during the working process, the mold after the material distribution is first vibrated for a set time by the strong vibrating device, and then the mold after the material distribution is vibrated for a set time by the weak vibrating device. When both vibrating devices 13 are strong vibrating devices, during the working process, the mold after the material distribution is vibrated for a set time by the two strong vibrating devices respectively. The present application sets a vibrating device 13 at the material distribution station 1, so as to vibrate the mold after the material is distributed, so as to eliminate bubbles in the product, make the concrete more dense and uniform, and thus ensure the quality of the produced product.

[0101] The first transfer line 21 in the present application is also preferably configured to transfer molds between the material distribution station 1 and the material distribution station 1 and the curing kiln 3.

The first conveying device is located between the first end wall 41 and the second end wall 42, wherein the conveying path of the first conveying device extends from the first opening 411 to the second opening 421.

[0124] It should be noted that the shapes and sizes of the "first opening" and the "second opening" in the present application are not specifically limited, and they can be any shapes and sizes that allow the mold and the mold table to pass through. Figures 4 to 6 As shown, the first opening 411 and the second opening 421 are both arranged in a square shape. In specific implementation, one of the first opening 411 and the second opening 421 can be selectively used as a mold entry point, and the other of the two can be used as a mold exit point.

[0126] like Figures 4 to 6 As shown, the second conveying device 44 is connected to the first end wall 41 and the second end wall 42 respectively and is located between the first end wall 41 and the second end wall 42. Figure 6 and Figure 8 As shown, the second conveying device 44 includes a second conveying drive motor 441 and a second conveying unit 442 directly opposite to the first conveying device. The second conveying unit 442 is transmission-connected to the second conveying drive motor 441, and the second conveying unit 442 is configured to be able to move toward or away from the first conveying device as a whole. In a specific implementation, the second conveying drive motor 441 is electrically connected to the control unit and is controlled by the control unit.

Figure 1 and Figure 2As shown, the composite prefabricated component production line includes a small prefabricated component transfer line 30, and the small prefabricated component transfer line 30 has a position for transmission in alignment with the second conveying unit 442, so that the demoulded small prefabricated components can be transferred to the small prefabricated component stacking station 10 through the second conveying unit 442 and the small prefabricated component transfer line 30. In specific implementation, it is preferred to set an automatic stacking device for stacking small prefabricated components at the small prefabricated component stacking station 10. This makes the production of small prefabricated components more automated.

[0128] The present application enables the flip demoulding equipment 4 to include a first conveying device, a second conveying device 44 and a control unit, and enables the first conveying drive motor 431 and the first conveying unit 432 included in the first conveying device to be transmission-connected, and enables the second conveying drive motor 441 and the second conveying unit 442 included in the second conveying device 44 to be transmission-connected, and further enables the first conveying drive motor 431, the second conveying drive motor 441 and the supporting wheel drive motor 4711 to be controlled by the control unit, thereby enabling the flip demoulding equipment 4 to better meet the needs of automated demoulding and transportation of the prefabricated component production line.

Specifically, the second conveying unit 442 can be moved to an appropriate position toward the first conveying unit 432 before flip demoulding, so that the prefabricated components that have been separated from the mold can be better received during the flipping and demoulding process. It can effectively prevent the prefabricated components from slipping out of the mold and falling from a high position during the flipping process, and can shorten the falling distance of the prefabricated components during the demoulding process. In this way, the quality and yield rate of the prefabricated component products can be better guaranteed. At the same time, the impact load generated by the prefabricated components during the demoulding process can be reduced to better improve the working condition of the second conveying unit 442 and reduce the maintenance cost of the equipment.

Specifically, when the product to be produced is a sleeper, the flip demoulding device 4 is in the second state, and the flip demoulding can convey the un-demolded sleeper product through the first conveying device. When the product to be produced is a small prefabricated component, the flip demoulding device 4 switches between the first state and the second state to realize the demoulding process of the small prefabricated component.
