Description

Technical Field

[0001] This utility model relates to the field of access gate technology, and in particular to a worker access gate for safety management in bridge and tunnel engineering. Background Technology

[0002] As a crucial component of modern transportation construction, bridge and tunnel engineering has always placed a high priority on safety management for construction companies. To ensure the smooth progress of construction and the safety of workers, bridge and tunnel construction sites require an efficient and reliable worker access control system. This system not only effectively manages personnel information but also mitigates potential safety risks to a certain extent. Worker access control systems for bridge and tunnel engineering safety management are primarily used for identity verification and recording of personnel entering and exiting the construction area. Through a facial recognition device installed on top of the gate, the system captures and identifies the facial images of workers entering and exiting, ensuring that only authorized personnel can enter the construction area. This mechanism not only improves the security of the construction area but also helps construction companies effectively manage worker attendance.

[0003] In practical applications, facial recognition devices play a crucial role. However, because facial recognition devices are exposed to the external environment for extended periods, especially in complex bridge and tunnel construction environments, and are exposed to adverse factors such as dust, moisture, and temperature fluctuations when not in use, their performance and stability are easily affected, leading to frequent malfunctions. This not only affects the normal use of access gates but may also pose potential risks to construction safety management. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a worker access gate for safety management in bridge and tunnel engineering, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a worker access gate for safety management in bridge and tunnel engineering, comprising an assembled base frame. A main gate and two side gates are bolted to the top surface of the assembled base frame. The main gate is located between the two side gates. Card readers are embedded in the top of both the main gate and the side gates. Each side gate has a groove on its outer side, and a receiving tube is bolted to the top of each side gate. The two receiving tubes are located inside the two grooves. Two symmetrically arranged electric push rods are fixedly installed inside each groove. A control ring is fixedly connected to the output ends of the two electric push rods. Two symmetrically arranged connecting plates are fixedly connected to the inner wall of the control ring. A bearing plate is fixedly connected between the two connecting plates. Both the bearing plate and the connecting plates are slidably connected to the receiving tubes. A face recognition device is bolted to the top surface of the bearing plate. The top of the face recognition device is located inside the receiving tube. The face recognition device is connected to the side gates via cables.

[0007] Preferably, in any of the above schemes, a sealing plate is fixedly installed on the outside of the side gate by bolts, and the sealing plate corresponds to the groove.

[0008] Preferably, in any of the above embodiments, a top ring is fixedly connected to the top of the face recognition machine, and a transparent glass plate is glued to the inner wall of the top ring, with the top ring corresponding vertically to the storage tube.

[0009] Preferably, in any of the above schemes, the top of the assembly base frame is fixedly connected with a plurality of linear array limit frames, and the main gate and the two side gates are slidably connected to the plurality of limit frames respectively.

[0010] Preferably, in any of the above schemes, the bottom surfaces of the main gate and the two side gates are fixedly connected with sealing strips, and the top surface of the assembled bottom frame is provided with a number of sealing grooves, which are respectively connected to the interior of a number of limiting frames. The sealing strips are slidably connected to the assembled bottom frame through the sealing grooves.

[0011] Preferably, in any of the above schemes, a plurality of cable trays are embedded in the top of the assembly base frame, and cable trays are provided at the bottom of the main gate and the two side gates, with the top of the cable trays located inside the cable trays.

[0012] Preferably, in any of the above solutions, the outer surface of the storage tube has two symmetrically arranged connecting grooves, and the two connecting plates are slidably connected to the storage tube through the two connecting grooves.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. When a worker access gate is required, the assembly base frame can be poured onto the ground with concrete, and the connection end of the wiring can be inserted into the wiring conduit. Then, the main gate and two side gates are inserted into several limit frames, and bolts are used to lock the main gate and two side gates onto the assembly base frame. After installation, the sealing strip will be embedded into the sealing groove, which greatly improves the sealing performance between the main gate, side gates and the assembly base frame. The access gate can be quickly assembled. The limit frames can limit the distance between the main gate and side gates without the need for measurement, making installation more convenient. After the construction personnel are verified by the facial recognition machine or card reader, the pedestrian access gate opens, and the construction personnel can enter and exit the passage. At the same time, the system will automatically record the personnel's name, job type, entry time and number of personnel for easy personnel management.

[0015] 2. When the worker access gate is not in use, the electric push rod can be activated to drive the control ring downwards. Through the transmission of the connecting plate, the bearing plate can be driven downwards until the top surface of the top ring is in contact with the top surface of the side gate. At this time, the face recognition machine will be stored inside the storage tube, preventing the face recognition machine from being exposed to adverse factors such as dust, moisture, and temperature changes for a long time, which greatly improves the performance and stability of the face recognition machine.

Two symmetrically arranged connecting plates 9 are fixedly connected to the inner wall of the control ring 8. A bearing plate 10 is fixedly connected between the two connecting plates 9. Both the bearing plate 10 and the connecting plates 9 are slidably connected to the receiving tubes 6. A face recognition machine 11 is fixedly installed on the top surface of the bearing plate 10 by bolts. The top of the face recognition machine 11 is located inside the receiving tubes 6.

[0025] As an optional technical solution of this utility model, a sealing plate 12 is fixedly installed on the outside of the side gate 3 by bolts. The sealing plate 12 corresponds to the groove 5. The setting of the sealing plate 12 facilitates the maintenance of the equipment inside the groove 5.

[0026] As an optional technical solution of this utility model, a top ring 13 is fixedly connected to the top of the face recognition machine 11. A transparent glass plate 20 is glued to the inner wall of the top ring 13. The top ring 13 corresponds to the storage tube 6, and the face recognition machine 11 will be stored inside the storage tube 6. This prevents the face recognition machine 11 from being exposed to adverse factors such as dust, moisture, and temperature changes for a long time, which greatly improves the performance and stability of the face recognition machine 11.

[0027] As an optional technical solution of this utility model, the top of the assembly base frame 1 is fixedly connected with several linear array limit frames 14. The main gate 2 and the two side gates 3 are slidably connected to several limit frames 14 respectively. The setting of the limit frames 14 can limit the distance between the main gate 2 and the side gates 3 without the need for measurement work, making the installation more convenient.

[0028] As an optional technical solution of this utility model, the bottom surfaces of the main gate 2 and the two side gates 3 are all fixedly connected with sealing strips 15. The top surface of the assembly base frame 1 is provided with several sealing grooves 16, which are respectively connected to the interior of several limiting frames 14. The sealing strips 15 are slidably connected to the assembly base frame 1 through the sealing grooves 16. After installation, the sealing strips 15 will be embedded in the sealing grooves 16, which greatly improves the sealing performance between the main gate 2, the side gates 3 and the assembly base frame 1.

[0029] As an optional technical solution of this utility model, a number of cable trays 17 are embedded in the top of the assembly base frame 1. The bottom of the main gate 2 and the two side gates 3 are provided with cable tray grooves 18. The top of the cable trays 17 is located inside the cable tray grooves 18. The cable trays 17 are set to facilitate cable laying operations.

[0030] As an optional technical solution of this utility model, two symmetrically arranged connecting grooves 19 are opened through the outer surface of the storage tube 6. The two connecting plates 9 are slidably connected to the storage tube 6 through the two connecting grooves 19. The electric push rod 7 is turned on to drive the control ring 8 to move downward. Through the transmission of the connecting plate 9, the bearing plate 10 can be driven to move downward, so as to control the lifting and lowering of the face recognition machine 11.

[0031] A worker access gate for safety management in bridge and tunnel engineering operates on the following principle:

[0032] 1): When the worker access gate is to be used, concrete can be used to pour the assembly base frame 1 on the ground, and the connection end of the wiring can be inserted into the wiring pipe 17. Then, the main gate 2 and the two side gates 3 are respectively inserted into several limit frames 14, and bolts are used to lock the main gate 2 and the two side gates 3 onto the assembly base frame 1.

[0033] 2): After the construction personnel are verified by the face recognition machine 11 or the card recognition device 4, the pedestrian passage will open, and the construction personnel can enter and exit the passage. At the same time, the system will automatically record the personnel's name, job type, entry time and number of personnel to facilitate personnel management.

[0034] 3): Activate the electric push rod 7 to drive the control ring 8 to move downward. Through the transmission of the connecting plate 9, the bearing plate 10 can be driven to move downward until the top surface of the top ring 13 is in contact with the top surface of the side gate 3. At this time, the face recognition machine 11 will be stored inside the storage tube 6.

[0035] In summary, the worker access gate for safety management in this bridge and tunnel project can be assembled by pouring concrete onto the ground to install the base frame 1, inserting the cable connector into the cable conduit 17, and then inserting the main gate 2 and two side gates 3 into several limiting frames 14. Bolts are then used to lock the main gate 2 and the two side gates 3 onto the base frame 1. After installation, the sealing strip 15 is embedded in the sealing groove 16, greatly improving the sealing performance between the main gate 2, side gates 3, and the base frame 1. This allows for rapid assembly of the access gate. The limiting frames 14 limit the distance between the main gate 2 and the side gates 3 without requiring measurement work. Installation is more convenient. After construction workers are verified by the face recognition machine 11 or the card reader 4, the pedestrian passage opens, allowing them to enter and exit. At the same time, the system will automatically record the name, job type, entry time, and number of personnel for easy management. When the worker access gate is not in use, the electric push rod 7 can be activated to drive the control ring 8 downward. Through the transmission of the connecting plate 9, the bearing plate 10 can be driven downward until the top surface of the top ring 13 is in contact with the top surface of the side gate 3. At this time, the face recognition machine 11 will be stored inside the storage tube 6, preventing the face recognition machine 11 from being exposed to dust, moisture, temperature changes, and other adverse factors for a long time, which greatly improves the performance and stability of the face recognition machine 11.
