Description

Technical Field

[0001] The utility model belongs to the technical field of traffic monitoring, and in particular relates to a cross arm with a movable bracket. Background Art

[0002] With the rapid development of social economy, the acceleration of urbanization, the continuous improvement of people's living standards, and the rapid increase in urban transportation demand, transportation problems have become a major problem that plagues urban development.

[0003] In order to alleviate urban traffic congestion, handle emergencies, and ensure the safety of pedestrians, the construction of a smart traffic holographic intersection system utilizes the integrated perception method of radar + video at the intersection. On the basis of ensuring the original normal non-site law enforcement functions, it uses the industry's latest sensor technology, AI algorithms, high-computing chips, and edge computing technology to achieve the fitting of radar data, video analysis data, and intersection channelization data, forming a variety of metadata such as vehicle spatiotemporal data, passing vehicle identity data, illegal capture data, lane flow data, and traffic light status data, to establish a full-dimensional, three-dimensional urban traffic intersection holographic supervision system, effectively enhance urban traffic supervision, and improve incident handling and response capabilities.

[0004] Holographic intersection equipment is usually installed on electric police poles or traffic light poles. However, many electric police poles and traffic light poles currently have many non-site law enforcement devices installed on their cross arms, leaving no extra space for other equipment. Setting up new poles will waste land, so there is an urgent need for a cross arm that can use existing poles for installation and that can save space and accommodate more equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a cross arm with a movable bracket to solve the problem that the existing cross arm in the background technology has no fixed position of the holographic intersection equipment due to the large number of law enforcement equipment. At the same time, by using the existing pole body for clamping, the problem of land waste is solved and the engineering efficiency is improved.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cross arm with a movable bracket comprises: a rod body, a cross arm and a movable mounting frame, wherein the cross arm holds the rod body via a holding plate arranged at the end; the movable mounting frame is sleeved on the cross arm, and the top and bottom of the movable mounting frame are respectively connected to a first device and a second device via a connecting piece.

[0008] Furthermore, a limiting bolt is provided at the end of the cross arm away from the rod body to prevent the mobile mounting bracket from falling.

[0009] Furthermore, the connecting member includes a connecting seat and a fixing seat, the connecting seat base is connected to the mobile mounting frame, and the fixing seat base is connected to the first device or the second device.

[0010] Furthermore, the connecting seat is provided with a through hole, and the fixing seat is provided with an arc groove, and the positions of the arc groove and the through hole correspond to each other. After the angle is set, the connecting seat and the fixing seat are fixed by bolts.

[0011] Furthermore, a support body is provided at the lower part of the cross arm, and the support body is provided with a plurality of wire entry and exit holes.

[0012] Furthermore, the holding plate is clamped on the rod body by U-shaped bolts.

[0013] Furthermore, the first device is a radar video camera, and the second device is a trinocular flow camera.

[0014] Furthermore, the movable mounting frame is fixed on the cross arm by connecting bolts.

[0015] Furthermore, the support body is in the shape of an arc.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model completes the preliminary installation of the cross arm by setting a holding plate at the end of the cross arm to hold the rod body, and then sets the mobile mounting frame on the cross arm, and the first device and the second device are respectively fixed on the top and bottom of the mobile mounting frame, so that the two devices can move synchronously and cooperate with each other. In this way, on the one hand, it can solve the problem that it is difficult to carry out the construction of a new rod body due to long approval time and high engineering cost, and on the other hand, the device solves the problem that the cross arm cannot install more equipment due to the large number of equipment by fixing the mobile mounting frame up and down, thereby increasing the accommodation space.
