DETAILED DESCRIPTION

[0021] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 6 As shown, a fully automatic sliding shielding door in the embodiment of the first aspect of the utility model includes a door body 1, a door body connecting plate 6, a longitudinal slider 8, a longitudinal beam 7, a cross beam 9, a cross slider 14, a longitudinal displacement drive device and a cross displacement drive device; the top of the door body 1 is connected to the door body connecting plate 6, and the longitudinal slider 8 arranged on the top of the door body connecting plate 6 is slidably connected to the longitudinal beam 7, and the longitudinal displacement drive device is used to drive the longitudinal slider 8 to slide back and forth along the longitudinal beam 7; cross sliders 14 are fixed at both ends of the longitudinal beam 7, and the cross slider 14 is slidably connected to the cross beam 9, and the cross displacement drive device is used to drive the cross slider 14 to slide back and forth along the cross beam 9.

[0024] In the above embodiment, it should be noted that the shielding door utilizes a top rail, with the entire shielding door leaf suspended on it. The rail is fixed to the darkroom's supporting steel structure. The entire control process utilizes an electric drive and electric locking system. The shielding door consists of multiple components: door leaf, door frame, suspension drive mechanism, locking mechanism, control system, threshold, and safety guards.

[0025] Steel structure support: After leaving a clearance width in front of the shield door, independent steel structures are used on both sides for support. The steel structure's top features a lattice structure to minimize deformation, and modular columns save space and increase overall rigidity. The steel structure is designed to have a deformation limit of no more than 1 / 500, meeting the structural deformation requirements of the shield door's sliding motion. It also meets the seismic fortification requirements of the eight major cities. The steel structure is sprayed with anti-corrosion paint, ensuring a corrosion resistance of at least 15 years.

[0026] Door body: Shielded doors have a large net opening area. Using an integral door body would result in severe welding deformation, making closing and locking difficult. Therefore, an assembled design should be used. Specifically, the door frame is constructed from steel beams assembled with high-strength bolts, with elliptical holes cut into them for tolerance adjustment to ensure assembly accuracy. The interior of the shielded door body is assembled using standard shielding panels, fabricated in the same manner as standard shielding bodies. Non-welding eliminates the effects of welding deformation. The inner surface of the door body can be fitted with pendants for attaching absorbing materials. Installation of these pendants should not affect shielding effectiveness. Shielded doors are heavy, and the center of gravity remains largely unchanged after attaching the absorbing material. Therefore, the impact of the absorbing material's weight on the door does not need to be considered.

[0027] The door frame's size and position correspond to the door leaf, which is locked to the door frame via locking mechanisms around its perimeter to achieve electromagnetic shielding. The door frame should be welded integrally. For transportation purposes, it can also be spliced, designed as multiple modules for on-site assembly. The door frame is welded or spliced ​​to the shielding steel plate of the shielding enclosure, forming a single unit. The installation process should be consistent with that of the shielding enclosure. The locking mechanism is directly fixed to the steel beam. The high-strength steel beam limits deformation of the insert blade and spring, while ensuring both in-plane and out-of-plane rigidity.

[0028] The shielding door's body and frame are secured with a knife and spring, ensuring shielding effectiveness. Traditional straight knife and spring designs require minimal tolerance in the operation of the shielding door; otherwise, locking failures or mislocking can occur, leading to deformation and unusability. To meet the tolerance requirements of large shielding doors, a unique knife and spring design with an outward opening angle is employed. This allows the shielding door to lock even with slight deviations in its operating position. Furthermore, the specially designed opening angle significantly reduces locking force while ensuring high shielding effectiveness.

[0029] The suspension and driving mechanisms are linked to enable the shielding gate leaves to move on the top guide rail.

[0030] A supporting steel structure is erected at the installation location of the shielding door, which is connected to the steel structure of the darkroom shielding shell to form a whole and ensure consistent style. At the same time, in order to prevent the large-sized door body from deformation, multiple horizontal and vertical supporting structures are added to the door body to ensure the strength of the door body and stabilize the relationship between the movable door body and the supporting steel structure.

[0031] The shielding door has a heavy weight. To ensure strength and rigidity during operation, the wheel set design refers to the design method of the beam crane. Multiple sets of high-strength wheel sets are directly hung on the H-shaped steel beam. To ensure flatness, stainless steel plates are attached to the contact surface between the steel beam and the wheel set to ensure smooth operation. The movement of the door leaf is divided into two parts: one is the longitudinal walking mechanism. After the door leaf and the door frame are released, they move backward, allowing the wave-absorbing spikes on the shielding door to completely exit the shielding shell.

[0032] After the wave-absorbing spikes on the shielded door have completely exited the shielding shell, the drive structure drives the door leaves to move horizontally, making room for the door entrance and exit. This movement is completed by the door's horizontal drive system.

[0033] When the shielding door leaf reaches the closed position, the guide wheels on the leaf and the Y-shaped slots in the door frame ensure precise alignment between the leaf and the door frame. The shielding door uses an electric or activated locking mechanism installed inside the leaf. This mechanism uses a pneumatic cylinder or reduction motor to synchronously drive the locking points of the shielding door, locking or releasing the door leaf and door frame. To ensure synchronous locking and overall rigidity of the shielding door, the spacing between each locking point should be controlled at approximately 2m. This will result in approximately 25 locking points around the entire shielding door to ensure that no force is applied to each locking point. Ensuring the synchronous movement of all locking points is crucial. Large sliding doors are designed to utilize a single drive chain, with all locking points driven by the same stainless steel chain, resulting in synchronized locking displacement and depth.

[0034] When the shielding door is opened, a trench forms between the ground and the threshold after the doors are removed, hindering the movement of equipment and personnel. Therefore, a lifting platform is required at the threshold to fill the gap between the ground and the threshold after the doors are removed. For ease of use, the lifting platform is constructed in two sections, each 6.5 meters wide. Each time the shielding sliding door is opened, the corresponding lifting platform automatically rises and falls. This design allows large sliding shielding doors to operate in two different opening positions: 6.5m and 13m. The lifting platform should be pneumatically or electrically operated. After the shielding door is opened, it automatically rises under the control of the control system, flush with the threshold, and has a load-bearing capacity of at least 10 tons. It automatically descends under the control of the control system before the shielding door closes.

[0035] The shielding door control system is installed on the side of the shielding door for easy control. Once installed, it provides one-touch door opening and closing functions. Its main components include a PLC (Programmable Logic Controller), drive components, and safety protection components.

[0036] The shielding door is controlled using a PLC touchscreen LCD screen, offering intuitive display and easy operation. The PLC controller provides various system data, including motor operating status and resistance levels of various components. In the event of a fault, the LCD display provides preliminary information on the cause and allows for simple correction. The PLC controller also provides a network interface and delivers shielding door status data and control instructions via the Modbus network protocol.

[0037] The shielding door is driven by a single motor, ensuring that its operating position can be determined by the position of the drive motor. This ensures that even in the event of a power outage or misoperation, the door's position can be instantly determined and subsequent actions can be taken upon power restoration, preventing any misoperation. The shielding door's drive functions are as follows: Opening: When the open button is pressed, the door first releases its engagement with the door frame and then slowly withdraws. Once the absorbing material is completely removed from the shielding shell, it then moves laterally to clear the entrance and exit passage for the shielding door. Closing: Pressing the close button performs the opposite action of opening the door.

[0038] To ensure safe gate control, the shielded gate is equipped with a variety of sensors to ensure the gate is immediately brought to a safe state if a problem arises, thus preventing potential safety issues. Door and track position sensors ensure the gate is properly positioned before locking. They also enable targeted acceleration, deceleration, and stopping during movement. Limit protection provides both electrical and mechanical limit protection. Electrical limit switches are installed at each end of the travel mechanism. If the positioning detection switch fails after the door leaf has moved horizontally, causing the gate to continue moving forward, the electrical limit switches in the travel mechanism will trigger, shutting off power to the gate. Behind the electrical limit switches are mechanical limit switches. If both the positioning detection switch and the electrical limit switch fail, the mechanical limit switches will protect the gate without causing damage. Motor protection includes motor torque protection and locking torque protection. If a significant obstruction is encountered during gate movement or locking, the gate will immediately stop. Infrared sensors use infrared detection within the gate's horizontal movement area to prevent equipment and personnel from passing through during movement. Once a person or equipment enters the gate's moving area, the gate will automatically stop moving.
