Description

Technical Field

[0001] This utility model relates to the technical field of line maintenance devices, and in particular to an auxiliary maintenance device for high-speed monitoring lines. Background Technology

[0002] A high-speed monitoring line is a system used to monitor various aspects of highways in real time, including traffic conditions, facility status, and environmental factors. It acts like the "nervous system" of the highway, collecting information through various sensors and monitoring equipment and transmitting this information to the monitoring center so that managers can understand the highway's operation and make appropriate decisions. Highways are generally long and are usually maintained in sections, each section being tens or even hundreds of kilometers long. Maintenance typically involves driving maintenance vehicles along the highway. However, some high-speed monitoring lines are located on gantries along the highway, such as speed measurement, monitoring, and ETC toll collection lines. Maintenance personnel need to use ladders to climb up for these lines. Considering the construction environment, the lack of targeted auxiliary maintenance devices poses significant safety hazards and is extremely inconvenient for maintenance. To address these issues, this invention provides a solution. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary maintenance device for high-speed monitoring lines.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A high-speed monitoring line auxiliary maintenance device includes a base, a lifting frame, and a construction platform. The base is installed on the rear compartment behind the vehicle body, the lifting frame is installed on the base, and the construction platform is installed on top of the lifting frame. The base includes a mounting seat, a support seat, and a rotating seat. The mounting seat is fixedly installed on the rear compartment, the support seat is fixedly installed on the mounting seat, and the rotating seat is rotatably installed on the support seat. A fixing mechanism is also provided between the rotating seat and the support seat to restrict the rotation between the rotating seat and the support seat. One side of the construction platform is connected to a telescopic platform via a telescopic mechanism, and a protective railing is installed on the telescopic platform.

[0006] Furthermore, the lifting frame is a shear-type lifting frame. The lower end of the lifting frame is mounted on two lower sliders, which are respectively threaded to both ends of a double-threaded rod. The threads at both ends of the double-threaded rod are arranged in opposite directions. The two ends of the double-threaded rod are mounted on a lifting seat via bearings. The lifting seat is mounted on a rotating seat. One end of the double-threaded rod is connected to a lifting crank. One side of the upper end of the lifting frame is hinged to a fixed hinge support at the bottom of the construction platform, and the other side of the lifting frame is hinged to an upper slider. The upper slider is installed in a groove at the bottom of the construction platform.

[0007] Furthermore, the fixing mechanism includes a positioning rod disposed on the side wall of the rotating seat and a positioning disk disposed on the outer wall of the support seat. One end of the positioning rod is hinged to the side wall of the rotating seat, and the outer circumference of the positioning disk is provided with evenly distributed slots. The positioning rod rotates along the hinge position and engages with the slots, so that the rotating seat cannot rotate relative to the support seat.

[0008] Furthermore, the telescopic mechanism includes a telescopic rod, a translation seat, a translation threaded rod, a translation crank, and a telescopic groove. The telescopic groove is located on the side of the construction platform near the telescopic platform, and the telescopic rod is located on the side of the telescopic platform facing the telescopic groove. The outer end of the telescopic rod is inserted into the telescopic groove. Two translation seats are respectively installed on opposite sides of the construction platform and the telescopic platform. One end of the translation threaded rod is mounted on the translation seat on the telescopic platform via a bearing, and the translation crank is fixedly connected to the mounting end of the translation threaded rod. The translation threaded rod is threadedly engaged with the translation seat on the construction platform.

[0009] Furthermore, the protective railing has an arc-shaped structure, and the notch of the arc-shaped protective railing is located on one side of the translation handle.

[0010] In summary, the present invention has the following beneficial effects: the line auxiliary device designed in this invention is installed on the maintenance vehicle and can realize vertical lifting, horizontal rotation and extension, so that maintenance personnel can maintain some sections of the highway without leaving the vehicle, reducing safety hazards and improving maintenance efficiency.
