Description

Technical Field

[0001] The utility model relates to the technical field of information engineering, in particular to an arc-shaped canopy camera installation connector for railway information engineering. Background Art

[0002] In the construction of customer service information in today's stations, video surveillance systems are one of the key processes. High-speed railway stations have a large passenger flow and a complex environment, making them key surveillance sites. Station attendants can use the monitoring system to accurately grasp the passenger flow and public security order in the square in front of the station, the ticket hall, the waiting room, the entrance, the exit, etc.

[0003] Among them, the monitoring on the platform is the most stringent, and the monitoring range is also required to cover all blind spots. This increases the difficulty of installing cameras on the platform. In small and medium-sized stations, the platform is generally cast in concrete, and for platforms with special structures, an arc-shaped top beam is designed to increase the bearing capacity of the canopy. Faced with such a platform canopy that is cast in concrete and designed with an arc-shaped top beam. When installing the camera, it is necessary to consider how to fix it stably and reliably on the arc-shaped top beam without damaging the canopy structure.

[0004] The existing technical solutions often embed the fixings in advance at the installation site, and then directly install the camera boom. However, facing such a curved installation surface, the above traditional method will expose most of the embedded parts to the outside, which not only cannot prevent the exposed parts from being corroded by external connections, but also increase the hidden dangers in the later stage, and it is not beautiful. For such a concrete poured and relatively complex curved installation surface, a connector that can adapt to a variety of complex installation environments and is easy to install is needed.

[0005] At present, for cameras installed under platform canopies, the camera hoisting parts are directly installed after the embedded parts are embedded before pouring concrete. However, the traditional platform canopy camera installation method can only adapt to horizontal installation surfaces, and the installation environment is single. It is necessary to weld connectors of different structures to adapt to different installation environments and installation methods. In addition, the traditional platform canopy camera installation method uses welded connectors, which is time-consuming and labor-intensive to construct, and is not very safe. It is necessary to consider the treatment of exposed steel bars, and it must be both beautiful and anti-corrosion. In addition, this type of welding of connectors of different structures has high requirements for design data. Before welding, a large number of parameters of the installation surface need to be tested. After welding, continuous retesting is required to calibrate the angle of the camera hanging parts.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0037] In order to solve the defects of the existing platform canopy camera installation environment being single, only being able to adapt to horizontal installation surfaces, and the installation construction being time-consuming and labor-intensive, as well as the low safety, a Figure 1 and Figure 2 The railway information engineering arc canopy camera installation connector shown. The connector 200 is installed on the arc beam 101 of the platform canopy 100, and can adapt to installation surfaces with different arc angles. It only needs to be directly matched when installing the camera, and has the advantages of no need for welding and other operations, simple maintenance, efficient installation, and safe construction.

[0038] Specifically, the connecting member 200 is mainly composed of an upper connecting member 210 , a lower connecting member 220 and a double bolt connecting member 230 . The upper connecting member 210 and the lower connecting member 220 are connected as a whole by a bolt connecting member 230 . The double bolt connecting member 230 uses a first bolt 231 and a second bolt 232 .

[0039] The lower end of the upper connecting member 210 is hingedly connected to the upper end of the lower connecting member 220 by a first bolt 231, forming the turning center of the upper connecting member 210 and the lower connecting member 220. At the same time, the lower end of the upper connecting member 210 is also connected to the upper end of the lower connecting member 220 by a second bolt 232, with the first bolt 231 as the turning center point.

[0040] In order to achieve the purpose of limiting the connection with the first bolt 231 as the flipping center point, at least one arc groove for limiting the second bolt 232 is provided on the upper connecting member 210 or the lower connecting member 220, so that the upper connecting member 210 or the lower connecting member 220 can produce relative flipping to achieve the purpose of adjustable angle.

[0041] Therefore, combined with Figure 1 and Figure 2 As shown, the connector mainly consists of an upper connector 210 and a lower connector 220. The upper connector 210 is used to adapt to installation planes of different angles, and the lower connector 220 is used to connect the camera boom 300 and keep the camera boom 300 vertically installed on the horizontal plane. The upper and lower connectors are connected by a double-bolt connector 230, wherein the first bolt 231 is the load-bearing point between the upper and lower parts of the connector, and the second bolt 232 is a fixing bolt with adjustable upper and lower angles, which also bears part of the load of the upper and lower connectors.

[0042] In some of the embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the upper connecting member 210 includes an upper connecting base plate 211 and an upper connecting bracket 212. The upper connecting bracket 212 is two and is vertically installed on the upper connecting member 210 in a bilaterally symmetrical manner, and is provided with an upper connecting hinge hole 2121 and an upper connecting arc-shaped limiting hole 2122 from top to bottom, respectively, for installing the first bolt 231 and the second bolt 232.

[0043] In order to enable the upper connecting member 210 to be installed at the bottom of the arc-shaped beam 101 of the platform canopy 100, a first upper connecting through hole 2111 is opened at the center position of the upper connecting base plate 211, and a plurality of first upper connecting mounting holes 2112 are opened at intervals around the body, and the upper connecting base plate 211 is installed at the bottom position of the non-planar arc-shaped beam 101 by using expansion screws.

[0044] like Figure 2 and Figure 8 In order to achieve the adjustable flipping of the angle between the upper connecting member 210 and the lower connecting member 220, at least the arc-shaped limiting hole 2122 is designed as an arc notch structure, and its central angle relative to the first upper connecting hinge hole 2121 as the rotation center is 10-135°.

[0045] In addition, the upper connecting base plate 211 and the upper connecting bracket 212 are made of stainless steel or aluminum alloy, and have sufficient structural strength to meet the hoisting requirements of the camera boom 300 and the camera 400. The two upper connecting brackets 212 are vertically installed on the upper connecting base plate 211 by welding, and the structure is stable, firm, and has a long service life.

[0046] In some of the embodiments, Figure 6 , Figure 7 and Figure 8 As shown, the lower connecting member 220 includes a lower connecting base plate 221 and a lower connecting bracket 222. The lower connecting bracket 222 is two and is vertically installed on the lower connecting member 220 in a bilaterally symmetrical manner, and is provided with a first lower connecting hinge hole 2221 and a second lower connecting hinge hole 2222 from top to bottom, respectively, for installing the first bolt 231 and the second bolt 232.

[0047] In order to be able to fix the lower connecting member 220 to the upper end of the vertically arranged camera boom 300, a first lower connecting through hole 2211 is opened at the central position of the lower connecting base plate 221, and a plurality of first lower connecting mounting holes 2212 are spaced around the body, and expansion screws are used to fix the lower connecting base plate 221 to the upper end of the camera boom 300.

[0048] The two ends of the second bolt 232 are respectively hingedly installed in the upper connection and the second lower connection hinge hole 2222, which plays a role in fixing the second bolt 232. At the same time, the two ends of the second bolt 232 are respectively slidably installed in the arc-shaped limit hole 2122, so that the lower connecting member 220 can be flipped and slid in the second lower connection hinge hole 2222, so as to adjust the angle between the upper connecting member 210 and the lower connecting member 220 to a preset position, such as adjusting the camera boom 300 to be perpendicular to the horizontal plane.

[0049] It is worth noting that in order to ensure the structural stability of the camera mounting connector and avoid looseness between the upper connector 210 and the lower connector 220 after installation, after adjusting the angular position between the upper connector 210 and the lower connector 220, nuts are used at both ends of the second bolt 232 to lock and fix the upper connector 210 and the lower connector 220.

[0050] In addition, like the upper connecting member 210, the lower connecting base plate 221 and the lower connecting bracket 222 are made of stainless steel or aluminum alloy, and have sufficient structural strength to meet the hoisting requirements of the camera boom 300 and the camera 400. The two lower connecting brackets 222 are vertically installed on the lower connecting base plate 221 by welding, and the structure is stable, firm, and has a long service life.

[0051] like Figure 1 As shown, as a preferred application implementation, when the camera mounting connector is used and installed, the upper connecting base plate 211 of the upper connecting member 210 is fixedly connected to the bottom of the arc-shaped crossbeam 101, and the lower connecting bracket 222 of the lower connecting member 220 is fixedly connected to the camera boom 300. The camera boom 300 is arranged perpendicular to the horizontal plane, and the two ends of the crossbar at its lower end are respectively installed with cameras 400.

[0052] The working principle of the arc canopy camera installation connector for railway information engineering is as follows: during installation, the upper connector 210 with the arc notch only needs to be screwed to the "arc surface" at the bottom of the arc beam 101 to be tightly fixed; the lower connector 220 is fixed to the camera boom 300 by bolts. Under the action of gravity, the untightened second bolt 232 in the arc notch will slide to the "arc bottom" and remain perpendicular to the horizontal plane, so that the camera boom 300 connected below is perpendicular to the ground, thereby achieving the purpose of calibrating the angle.

[0053] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships.

In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
