Description

Technical Field

[0001] This utility model belongs to the field of intersection monitoring inspection and maintenance technology, and in particular relates to an intersection monitoring maintenance device. Background Technology

[0002] Intersection monitoring is an important component of urban traffic safety and order maintenance. It uses various types of surveillance cameras to monitor and record traffic conditions in real time. After a certain period of operation, intersection monitoring systems need to be inspected and maintained by staff. Therefore, intersection monitoring maintenance devices are needed to assist staff in the inspection and maintenance of intersection monitoring systems.

[0003] However, existing intersection monitoring and maintenance devices often lack auxiliary positioning functions, making it difficult to install them stably inside the vehicle. When staff perform maintenance operations on the lifting platform, the entire device may tip over, resulting in low safety. Utility Model Content

[0004] This utility model provides an intersection monitoring and maintenance device, which aims to solve the problem mentioned in the background art that existing intersection monitoring and maintenance devices often lack auxiliary positioning functions.

[0005] To solve the above problems, this utility model is implemented as follows: an intersection monitoring and maintenance device, comprising: a base; a hydraulic cylinder fixedly installed on the base; a connecting plate fixedly installed on the output rod of the hydraulic cylinder; a U-shaped frame fixedly installed on the connecting plate; an auxiliary positioning mechanism installed on the base, the auxiliary positioning mechanism being used to fix the base inside the vehicle body; and a lifting and maintenance platform mechanism installed on the U-shaped frame, the lifting and maintenance platform mechanism being used by personnel to stand on it to perform inspection and maintenance of the intersection monitoring system.

[0006] Preferably, the auxiliary positioning mechanism includes: a dual-axis motor fixedly installed on the inner wall of the bottom of the base; two transverse screws fixedly installed at both ends of the output shaft of the dual-axis motor and rotatably connected to the inner wall of the base; two sliding plates threaded onto the two transverse screws; a plurality of sliding rods fixedly installed on the side of the two sliding plates that is far from each other and slidably connected to the base; and two positioning plates fixedly installed on the side of the plurality of sliding rods that is far from each other.

[0007] Preferably, both positioning plates are provided with corrugated anti-slip pads, and the bottom of the base is provided with anti-slip foot pads.

[0008] Preferably, the lifting and maintenance platform mechanism includes: a longitudinal screw rotatably mounted on the U-shaped frame; a first servo motor fixedly mounted on the U-shaped frame and connected to the longitudinal screw; a lifting plate threaded onto the longitudinal screw; a maintenance platform fixedly mounted on the lifting plate; and a tool delivery mechanism disposed on the maintenance platform.

[0009] Preferably, a plurality of limiting rods are fixedly installed on the inner wall of the U-shaped frame, and the plurality of limiting rods are slidably connected to the lifting plate.

[0010] Preferably, the tool delivery mechanism includes: a horizontal shaft rotatably mounted on one side of the maintenance bench and having a drum; a pull rope disposed on the drum; a plurality of positioning ropes disposed at one end of the pull rope; a toolbox fixedly mounted on one end of the plurality of positioning ropes; a second servo motor fixedly mounted on the inner wall of the maintenance bench; a drive gear fixedly sleeved on the output shaft of the second servo motor; and a driven gear fixedly sleeved on the horizontal shaft and meshing with the drive gear.

[0012] Compared with related technologies, the intersection monitoring and maintenance device provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, the intersection monitoring and maintenance device provided in this solution uses a base as the supporting foundation for the entire device. The base is stably installed inside the vehicle, providing a solid installation platform for subsequent components. The hydraulic cylinder is the core component that drives the lifting and lowering of the device. Through precise control of the hydraulic system, the hydraulic cylinder can smoothly and reliably push the connecting plate and its components up and down, thereby adjusting the height of the lifting and maintenance platform mechanism to accommodate monitoring equipment at different heights for maintenance work. This design not only improves work efficiency but also greatly reduces the physical burden on the staff. The connecting plate acts as a bridge between the hydraulic cylinder and the U-shaped frame, ensuring that the thrust of the hydraulic cylinder can be effectively transmitted to the U-shaped frame and the lifting and maintenance platform mechanism. The design of the U-shaped frame takes into account both structural stability and ease of installation. It provides a stable installation platform for the lifting and maintenance platform mechanism, and its open structure also facilitates various operations by the staff during maintenance. The base is firmly fixed inside the vehicle through an auxiliary positioning mechanism to prevent the entire device from tipping over. The lifting and maintenance platform mechanism serves as the main working platform for staff to perform monitoring, inspection, and maintenance.

[0014] In summary, the intersection monitoring and maintenance device of the present invention achieves efficient, convenient, and safe maintenance of intersection monitoring equipment through the coordinated work of its components, greatly improving the efficiency and quality of maintenance work.

[0022] In this embodiment, the base 1 serves as the supporting foundation for the entire device. The base 1 is stably installed inside the carriage, providing a solid installation platform for subsequent components. The hydraulic cylinder 2 is the core component that drives the lifting and lowering of the device. Through precise control of the hydraulic system, the hydraulic cylinder 2 can smoothly and reliably push the connecting plate 3 and its components up and down, thereby adjusting the height of the lifting and maintenance platform mechanism to accommodate maintenance work on monitoring equipment at different heights.
