Description

Technical Field

[0001] This invention relates to the field of concrete air-raid shelter door production technology, and in particular to an assembly equipment and process for concrete air-raid shelter door panels. Background Technology

[0002] Civil defense doors are the entrances and exits of civil defense projects. They are airtight doors used in wartime and disaster relief projects, and concrete civil defense doors are a common type. Due to the large size of concrete civil defense doors, overhead cranes are essential equipment in their production. The concrete requires pouring and curing, resulting in relatively fixed production methods and equipment. The equipment is often dispersed, bulky, and occupies a large area. After production, the doors need to be transported and installed, but transporting them using overhead cranes is inconvenient, poses significant safety hazards, and involves complex construction steps. The production time for a single door is long, resulting in low production efficiency. Summary of the Invention

[0003] This invention proposes a civil defense concrete door assembly equipment, which solves the problems of current concrete door equipment being scattered, complex, occupying a large area, and having low production efficiency.

[0004] The technical solution of this invention is implemented as follows:

[0005] A civil defense concrete door assembly device includes an assembly platform with mounting holes. Below the assembly platform are mounting components that mate with the mounting holes. These mounting components are used for conveying and installing connecting cylinders. An auxiliary transport device is located above the assembly platform. An L-shaped plate is hinged to one end of the assembly platform to assist in vertically erecting the door leaf. Conveying platforms are located on both sides of the L-shaped plate. A support frame driven by a first hydraulic cylinder is located on the conveying platform. A second hydraulic cylinder is located at the end of the assembly platform furthest from the L-shaped plate. A suction cup for adsorbing the workpiece base plate is hinged to the end of the second hydraulic cylinder.

[0006] The conveyor platform is equipped with casters around its bottom and a limit plate on the side away from the assembly table. Several third hydraulic cylinders are mounted on the limit plate, and electromagnets are mounted at the ends of the third hydraulic cylinders to facilitate limiting the door panels and make the door panels more stable during transportation.

[0007] The auxiliary transport device includes a hanging rail, on which a first slider and a second slider are slidably mounted. A fourth hydraulic cylinder is mounted on the first slider, and a U-shaped clamp is mounted at the end of the fourth hydraulic cylinder. A fifth hydraulic cylinder is mounted on the second slider, and a support block is mounted at the end of the fifth hydraulic cylinder. Several support columns are mounted on the support block.

[0008] The installation components include a slide rail connected to the assembly table, a third slider that slides on the slide rail, a conveying block driven by a sixth hydraulic cylinder on the third slider, and a slot on the conveying block to facilitate the installation of the emergency connecting cylinder and improve assembly efficiency.

[0009] The assembly platform has auxiliary baffles on both sides, with pressure plates hinged to the auxiliary baffles. A fixing plate is located at the end of the assembly platform away from the L-shaped plate, and several springs are installed on the fixing plate. Limiting blocks are installed on the springs to limit the bottom plate of the door leaf and improve the assembly accuracy.

[0010] One assembly process for a civil defense concrete door includes the following steps:

[0011] S1. First, place the bottom plate of the door leaf on the assembly table, and align the bottom plate with the mounting hole.

[0012] S2, the connecting cylinder is assembled with the door leaf base plate through the mounting components and mounting holes, and then welded;

[0013] S3, assemble each concrete block using an auxiliary transport device, and simultaneously place the cover plate and weld it to the bottom plate of the door leaf;

[0014] S4, extend the second hydraulic cylinder to push the door leaf up through the suction cup, while the L-shaped plate rotates to lower the door leaf onto the support frame. At the same time, extend the first hydraulic cylinder to lift the door leaf and cooperate with the auxiliary transport device to move the door leaf away.

[0015] Beneficial effects

[0016] This invention improves the integration of assembly equipment by setting up installation components, installation holes, auxiliary transportation devices, and other components, while reducing the size and floor space of the equipment. The separate and movable conveyor platform facilitates the transfer and installation of door panels. At the same time, the use of concrete blocks for splicing assembly eliminates the need for on-site concrete pouring, shortens the door panel assembly time, improves production efficiency, and overcomes the limitations of site and equipment on door panel assembly, making it convenient for on-site assembly and installation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1 As shown, a civil defense concrete door assembly device includes an assembly platform 1 with mounting holes 28 on it. An installation component that mates with the mounting holes 28 is located below the assembly platform 1. An auxiliary transport device is located above the assembly platform 1. An L-shaped plate 20 is hinged to one end of the assembly platform 1. Conveying platforms 25 are located on both sides of the L-shaped plate 20. A support frame 24 driven by a first hydraulic cylinder 26 is located on the conveying platform 25. A second hydraulic cylinder 10 is located at the end of the assembly platform 1 away from the L-shaped plate 20. A suction cup 11 for adsorbing the bottom plate of the door is hinged to the end of the second hydraulic cylinder 10. The civil defense door in this embodiment includes a door bottom plate 30. Fixed columns are located around the bottom plate 30. Four concrete blocks 32 are located on the bottom plate 30. Cover plates for sealing are located on the fixed columns. A connecting cylinder 33 is passed through the center of the door. Temporary opening and closing doors are installed at both ends of the connecting cylinder 33. Several limiting holes 31 are located on one of the fixed columns.

[0023] The working principle of this embodiment is as follows: By designing a separate door leaf, the door leaf is divided into multiple assembly components, which are then assembled using integrated assembly equipment. This improves assembly efficiency while reducing the floor space occupied by assembly equipment and the overall volume of each piece of equipment. Furthermore, the auxiliary transport device and conveyor platform 25 allow for rapid transfer of the door leaf to the installation location. The conveyor platform 25 then assists in the installation of the door leaf, facilitating assembly and installation. First, the door leaf base plate 30 is placed on the assembly platform 1. Then, the connecting cylinder 33 is assembled and welded to the door leaf base plate 30 using the installation components. Four concrete blocks 32 are placed sequentially on the door leaf base plate 30 using an auxiliary transport device. Then, a sealing cover plate is placed on the concrete blocks 32 and welded to the door leaf base plate 30. After the door leaf is assembled, the second hydraulic cylinder 10 is extended to push the door leaf up. At the same time, the L-shaped plate 20 rotates the door leaf until the door leaf is vertical and the end of the door leaf close to the ground is directly above the support frame 24. Then, the first hydraulic cylinder 26 is extended to make the support frame 24 lock the end of the door leaf and push the door leaf out from the L-shaped plate 20. The door leaf is then transported through the conveyor table 25 and the auxiliary transport device.
