Description

Technical Field

[0001] An electromagnetic safety door structure for a production line rest area, which is used as a safety door for the temporary rest area of employees on an automobile assembly line, and relates to the technical field of the design and manufacture of an automatic electromagnetic safety door. Background Art

[0002] On an automobile production line, in order to ensure the safety of employees on the assembly line, relieve the labor intensity of assembly line employees, and protect the physical and mental health of assembly employees, during normal operation, rest areas for employees are set up on the production assembly line. There are fixed-time breaks in the morning and afternoon every day, so there are also employee rest areas on the automobile production line without exception. Generally speaking, the rest areas provided for employees on existing automobile assembly lines are basically set in places with space beside the production line. That is, a relatively fixed area is separated by relevant railing forms for employees' breaks during work. There are access channels in the rest area. Different from other operation lines, on the production line, there are vehicles that need to assemble parts passing by. Therefore, when employees enter and leave the rest area, they have to be very careful, otherwise there will be a collision accident with the passing vehicle in an instant when entering and leaving the rest area.

[0003] The utility model patent with the patent publication number CN219012376U discloses a left shaft door structure of a capsule bin, including a door body, a connecting plate and a connecting structure. The door body, the connecting structure and the connecting plate are connected by bolts. An electromagnetic door lock is inlaid in the middle of the end of the door body away from the connecting structure. In this left shaft door structure of the capsule bin, through the setting of the connection mode between the door body and the connecting structure, the door body can be quickly disassembled and assembled, which is convenient for the use of this structure. Through the setting of the reset structure, when the door body is opened, the door body drives the connecting column to rotate, the connecting column drives the fixedly connected chain ring to rotate, the chain ring drives the synchronous belt to rotate, and during the rotation of the synchronous belt, the reset spring deforms to release the restriction on the door body. The return force of the reset spring can drive the synchronous belt to rotate in the reverse direction, and then the door body can be reset. This structure can realize the automatic closing of the door body when it is opened, which is convenient for the use of this structure. The main problem solved by this technology is the problem that the capsule bin door cannot be automatically reset. The structure is relatively complex, with the characteristics of high cost and difficult installation, and is suitable for the locking and opening of a complete door structure. However, on the production line, since the set rest area is a temporary rest place, it is necessary to facilitate the entry and exit of employees and also have the transparent characteristic of observing moving targets inside and outside. Therefore, on the production line, rail-type doors are basically used. Therefore, this technology is not suitable for the doors of the temporary rest areas set on the production line.

[0004] In the prior art, for safety reasons, some production line rest areas need to be staffed with dedicated security personnel to observe the flow of vehicles and personnel, and timely remind employees entering and leaving the rest area to pay attention to the passing assembly vehicles to avoid production safety accidents. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present utility model designs an electromagnetic safety door structure for a production line rest area with automatic electromagnetic closing and automatic opening according to the characteristics of the relative movement of personnel and vehicles, including a safety area mechanism, a vehicle detection mechanism, and an electromagnetic attraction mechanism:

[0006] The safety area mechanism includes a sensor mounting rod, a rest area door post, an access crossbar, and a rest area railing. The sensor mounting rod is set on the roadside of the driving lane, and a downward vehicle sensor is provided on the crossbar of the sensor mounting rod.

[0007] Preferably: The sensor mounting rod is set on the roadside of the passage where the vehicle comes from in the rest area; after installing the vehicle sensor on the sensor mounting rod, the net clearance height between the lowest point of the vehicle sensor and the ground is higher than the height of the passing vehicle; the sensor mounting rod is set on the same side as the rest area, or can also be set on the other side opposite to the passage in front of the rest area.

[0008] One end of the access crossbar is connected to the rest area door post by a two-way return hinge, and the other end is provided with an electromagnetic attraction mechanism.

[0009] The vehicle detection mechanism includes a distribution box, a vehicle sensor, and an electromagnetic attraction mechanism; the distribution box is set on the rest area door post, the vehicle sensor is set on the crossbar of the sensor mounting rod, the vehicle sensor faces downward, and the vehicle sensor is powered by the distribution box; the vehicle passing data detected by the vehicle sensor is connected to the PLC processor in the distribution box by a wire.

[0010] The electromagnetic attraction mechanism is connected to the power supply of the distribution box by a wire.

[0011] The electromagnetic attraction mechanism includes a solenoid valve, a solenoid valve suction plate, a suction plate support nut, a suction plate connecting column, a spring mechanism, and an inner support plate.

[0012] The solenoid valve is fixedly set on the rest area door post, and the solenoid valve suction plate is set at the position on the access crossbar facing the fixedly installed solenoid valve.

[0013] The back of the solenoid valve suction plate is welded with a suction plate connecting column.

[0014] An inner support plate is provided on the inner surface of the end of the access crossbar where the electromagnetic attraction mechanism is installed.

[0015] Preferably, the suction plate connecting column passes through the front cover plate of the access crossbar, and an inner support plate is arranged inside the front cover plate. The rear end of the suction plate connecting column passes through the inner support plate;

[0016] The diameter of the end of the suction plate connecting column welded to the back of the solenoid valve suction plate is larger than the diameter after being arranged on the inner support plate;

[0017] The diameter of the suction plate connecting column after passing through the inner support plate is smaller than the diameter of the front end. A spring mechanism is arranged on the suction plate connecting column after passing through the inner support plate. The spring mechanism includes a suction plate support pillar nut and a rear thread of the suction plate support pillar;

[0018] Preferably, the upper end of the inner support plate is fixed by a fixing screw on the support plate, and the lower end of the inner support plate is fixed by a fixing screw under the support plate;

[0019] Preferably, a door railing front cover is arranged at the front end of the access crossbar, and the door railing front cover is fixedly connected by a door railing front cover screw.

[0020] The beneficial technical effects of the present utility model are as follows:

[0021] 1. The magnetic plate suction and automatic return mechanism of the present utility model adopts uniform spring pressure and is divided into two groups of solenoid valves and suction plates, which can maintain the suction stability. When installing, a gap of 5-6 mm is left between the electromagnetic block of the solenoid valve and the magnetic plate, which can ensure that the gap between the magnetic block and the magnetic plate can overcome the spring pressure and ensure firm and rapid suction;

[0022] 2. After the set sensing signal receives the signal that a vehicle has passed, a circuit is formed to trigger the relay. At the same time, the set disconnection time after the time relay is suctioned is not less than 10 seconds, which can well control the convenience of personnel entry and exit and vehicle passage. The access control crossbar of the security door can be opened bidirectionally. When the access control system senses a vehicle through the sensor, the electromagnetic block automatically suctions, and the access control plate cannot be opened. After 10 seconds, the solenoid valve is powered off, and the set spring pulls back the magnetic plate to open the access control crossbar.

[0023] 3. The set sensor is suspended at a height of 20 cm from the ground, which can prevent misoperation. Through the access control system of the security door, it can ensure that there are no safety concerns when personnel leave the rest area. Description of the Drawings

Detailed implementation

[0028] To more clearly and detailedly illustrate the structure and use of the present utility model, the following gives the best embodiment of the present utility model in conjunction with the attached drawings.

[0029] An electromagnetic safety door structure for a production line rest area includes a safety area mechanism, a vehicle detection mechanism, and an electromagnetic suction mechanism:

[0030] The safety area mechanism includes a sensor mounting rod 1, a rest area door post 3, an access cross - door rod 6, and a rest area railing 4. The sensor mounting rod 1 is arranged on both sides of the traffic lane 8. A downward - facing vehicle sensor 9 is provided on the sensor mounting rod 1. The sensor mounting rod 1 is arranged on the roadside of the access road on the side where the vehicle in the rest area comes. After installing the sensor 9 on the sensor mounting rod 1, the net clearance height between the lowest point of the sensor 9 and the ground should be higher than the height of the passing vehicle. For the convenience of installing the sensor 9, the sensor mounting rod 1 can be arranged on the same side as the rest area or on the other side of the workbench opposite to the access road in front of the rest area.

[0031] One end of the access cross - door rod 6 is connected to the rest area door post by a double - acting return hinge 5, and the other end is provided with an electromagnetic suction mechanism.

[0032] Vehicle detection mechanism: It includes a distribution box 2, a vehicle sensor 9, and an electromagnetic suction mechanism; the distribution box 2 is arranged on the door post 3 of the rest area, the vehicle sensor 9 is arranged on the cross bar of the sensor installation rod 1, the vehicle sensor 9 is arranged facing downwards, the vehicle sensor 9 is powered by the distribution box, and the vehicle passing data detected by the vehicle sensor 9 is connected to the PLC processor and relay in the distribution box through wires. The electromagnetic suction mechanism is connected to the power supply of the distribution box through wires; when the vehicle sensor 9 detects that a vehicle has passed, the signal is transmitted to the PLC processor in the distribution box 2 through wires and powers the relay. To ensure the safety of both personnel and vehicles passing through, when the PLC processor detects that a vehicle has passed, after the relay is turned on, it will energize the solenoid valve 10 arranged on the door post 3 of the rest area, causing the solenoid valve 10 to generate electromagnetic force. In this case, the solenoid valve suction plate 11 connected to the front end of the suction plate connection column 18 will generate a suction force, overcoming the elastic force of the spring mechanism 7 arranged at the rear end of the solenoid valve suction plate 11, and being sucked forward onto the solenoid valve 10, preventing the resting personnel from opening the access crossbar 6 for entering and leaving the rest area; after the vehicle has passed and the signal of vehicle passing is removed, when the PLC in the distribution box 2 determines that it is safe to enter and leave the rest area, it stops the relay from working, cuts off the power supply to the solenoid valve 10, and eliminates the electromagnetic force. At this time, the solenoid valve suction plate 11 loses the suction force, and the spring mechanism 7 at the rear end rebounds, driving the suction plate connection column 18 to pull backward. Without the suction force, the solenoid valve suction plate 11 sucked onto the solenoid valve 10 can be opened, and personnel can enter or exit.

[0033] The electromagnetic suction mechanism includes a solenoid valve 10, a solenoid valve suction plate 11, a suction plate support nut 14, a suction plate connection column 18, a spring mechanism 7, and an inner support plate 17; the solenoid valve 10 is fixedly arranged on the door post 3 of the rest area, and the solenoid valve suction plate 11 is arranged at the position on the access crossbar 6 facing and fixedly installing the solenoid valve 10; for the stability of the installation structure, the solenoid valve suction plate 11 is connected to the suction plate connection column 18 by welding on the back, and an inner support plate 17 is arranged on the inner surface of one end of the access crossbar 6 where the electromagnetic collection mechanism is installed.

[0034] Preferably: The suction plate connection column 18 welded to the back of the solenoid valve suction plate 11 can also be connected by drilling a hole and threading on the back of the solenoid valve suction plate 11, threading the front end of the suction plate connection column 18, and screwing it in with a thread.

[0035] The suction plate connecting column 18 penetrates into the front cover of the access horizontal door rod 6. In order to fix the suction plate connecting column 18, an inner support plate 17 is arranged inside the front cover, and the rear end of the suction plate connecting column 18 passes through the inner support plate 17; the diameter of one end of the suction plate connecting column 18 welded on the back of the solenoid valve suction plate 11 is larger than the diameter after the inner support plate 17 is arranged; the diameter of the suction plate connecting column 18 after passing through the inner support plate 17 is smaller than the diameter of the front end. A spring mechanism 7 is arranged on the suction plate connecting column 18 after passing through the inner support plate 17, and the spring mechanism 7 includes a suction plate support nut 14 and a rear thread of the suction plate support 15;

[0036] Preferably: the upper end of the inner support plate 17 is fixed by a fixing screw 13 on the support plate, and the lower end of the inner support plate 17 is fixed by a fixing screw 16 under the support plate;

[0037] Preferably: a front cover 19 of the door railing is arranged at the front end of the access horizontal door rod 6, and the front cover 19 of the door railing is fixedly connected by a door railing front cover screw 12.

[0038] Furthermore: The electromagnetic suction mechanism is a technology well-known to those of ordinary skill in the art. Therefore, the specific connection circuit and the model of the solenoid valve will not be elaborated here;

[0039] Furthermore: The suction plate connecting column 18 is a cylindrical structure with a larger front diameter than the rear diameter. Specifically, taking the inner support plate 17 arranged inside as the boundary, starting from the suction plate connecting column 18 fixed on the back of the solenoid valve suction plate 11 to the front of the inner support plate 17, the diameter of the suction plate connecting column 18 is larger than the diameter of the section where the spring mechanism 7 is arranged behind the inner support plate 17. Since the aperture arranged on the inner support plate 17 is the same as the diameter of the section with the rear thread 15 of the suction plate support arranged at the rear end, which is smaller than the diameter of the previous section of the suction plate connecting column 18, when the electromagnetic force disappears and the suction plate connecting column 18 returns under the spring rebound, the larger front section of the diameter of the suction plate connecting column 18 will be blocked by the arranged inner support plate 17. Therefore, the suction plate connecting column 18 will not completely retract into the access horizontal door rod 6.
