Description

Technical Field

[0001] This utility model relates to the field of road traffic equipment technology, and in particular to a rotating base for road traffic equipment. Background Technology

[0002] Existing road traffic barriers are generally fixed in place and cannot be moved once installed. Because their arms cross the road and their height is limited, they cannot accommodate oversized vehicles unless the barrier is temporarily removed. Furthermore, when maintenance is required on the equipment mounted on the barriers, the road needs to be closed for construction, disrupting traffic.

[0003] The main reason for the above problems is that the existing traffic poles are fixed in structure and cannot be rotated. Once installed, their position and angle cannot be adjusted, thus failing to meet the needs of oversized vehicles and equipment maintenance.

[0004] To solve this problem, a rotating base can be installed at the bottom of the traffic pole. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rotating base for road traffic equipment.

[0007] A rotating base for road traffic equipment is provided, comprising: a bottom assembly and a top assembly rotatably connected to the bottom assembly; wherein...

[0008] The bottom assembly has a bottom for connection with the base of the road traffic equipment, a first cavity for receiving the top assembly, and a top for limiting the position of the top assembly;

[0009] The top assembly is rotatably disposed within the first cavity, the top assembly having a top for connection with the base of the road traffic equipment and a second cavity for accommodating the road traffic equipment, the top of the top assembly being disposed above the top of the bottom assembly;

[0010] The bottom component has two limiting blocks at its top.

[0013] Preferably, it further includes: a bottom sealing plate; wherein,

[0014] The bottom sealing plate is disposed at the bottom of the top assembly, and the bottom of the top assembly is connected to the tapered roller bearing through the bottom sealing plate.

[0015] Preferably, it further includes: a positioning pin; wherein,

[0016] The bottom component has two first pin holes at its top, and the top component has a second pin hole at its top. The positioning pin passes through the second pin hole and one of the first pin holes in sequence to limit the relative position of the bottom component and the top component.

[0017] Preferably, the top of the top component is further provided with a hollow rotating square tube.

[0018] Preferably, a first oil injection nozzle is also provided on the side wall of the top component, and the first oil injection nozzle is connected to the tapered roller bearing disposed on the top.
