Abstract
The invention discloses a tower crane video surveillance system, which comprises a camera (9), a video cable (10), and a monitoring device. The key technology is as follows: the camera (9) is fixedly arranged on the outer surface of a tower crane pulley frame (6), and is connected with the monitoring device through the video cable (10), and the video cable (10) and a steel wire rope (7) penetrating through the tower crane pulley frame (6) synchronously pay off and take up through an automatic cable pay-off and take-up device. Figure 2 is an accompanying drawing in the abstract of the specification.
Description
Technical field
The present invention relates to a kind of video monitoring system, particularly a kind of tower crane video monitoring system.
Background technology
Tower crane is widely used in the shipping occasions such as building, harbour, due to tower crane sling weight place distance tower crane driver-operated place far away, tower crane in blind area, light bad greasy weather, at dusk, evening is when constructing, tower crane chaufeur does not see or not easily sees lifted weight clearly, unloads the situation of weight surrounding environment, the judgement easily made the mistake and accidents caused.
Summary of the invention
The object of this invention is to provide a kind of tower crane video monitoring system, it can make tower crane chaufeur no matter when blind area or can clearly see when light is bad lifted weight and unload situation around weight, the generation of minimizing accident effectively.
Task of the present invention completes in the following way:
A kind of tower crane video monitoring system, comprises camera, vision cable line, monitor unit, it is characterized in that: be fixed with camera at the outside face of tower crane pulley yoke; Described camera is coupled together by vision cable line and monitor unit; Described vision cable line is by vision cable line automatic retraction device and the synchronous unwrapping wire of steel rope working condition passed on tower crane pulley yoke, take-up.
Described vision cable line automatic retraction device comprises vision cable line pedestal, vision cable coil of wire dish, driving wheel, flower wheel, chain, described driving wheel is by being mechanically anchored on equipment mechanism main shaft, flower wheel is fixed on vision cable line pedestal, follower shaft is provided with vision cable coil of wire dish, use chain as Transmission between driving wheel and flower wheel, driving wheel and the transmission speed ratio of flower wheel meet the requirement equal with vision cable coil of wire dish retractable cable length of equipment mechanism forced stroke.
Owing to have employed such scheme, the present invention can make tower crane chaufeur no matter when blind area or can clearly see when light is bad lifted weight and unload situation around weight, the generation of minimizing accident effectively.
Accompanying drawing explanation
Fig. 1 is vision cable line automatic retraction device structural plan of the present invention schematic diagram.
Fig. 2 is camera installation site of the present invention schematic diagram.
In figure, each symbol represents:
1, equipment mechanism main shaft 2, driving wheel 3, chain 4, flower wheel 5, vision cable line pedestal 6, pulley yoke 7, steel rope 8, suspension hook 9, camera 10, vision cable line
Detailed description of the invention
With reference to Fig. 1, Fig. 2.In FIG, driving wheel 2 is by being mechanically anchored on equipment mechanism main shaft 1, and vision cable line pedestal 5 is bolted on apparatus body, and driving wheel 2 and flower wheel 4 carry out transmission by chain 3.When vision cable line pedestal 5 being provided with the work of vision cable coil of wire disc apparatus, driving wheel 2 is rotated by equipment mechanism main shaft 1, flower wheel 4 is driven to rotate by chain 3, the rotation of flower wheel 4 has driven vision cable coil of wire dish to rotate on vision cable line pedestal 5, thus reaches the object of folding and unfolding vision cable line.Driving wheel 2 and the transmission speed ratio of flower wheel 4 meet the requirement equal with vision cable coil of wire dish retractable cable length of equipment mechanism forced stroke.
In fig. 2, the outside face of pulley yoke 6 is fixed with camera 9, camera 9 is provided with vision cable line 10.
When tower crane works, pulley yoke 6 drops to specified position with steel rope 7, suspension hook 8, camera 9, vision cable line 10 simultaneously, the environment of surrounding and working condition are transferred to monitor unit by vision cable line 10 by camera 9, and tower crane chaufeur judges when lift by crane by monitor unit; After suspension hook 8 hangs on weight, when drop to specified position, tower crane chaufeur judges when and where put down weight by monitor unit, thus effectively reduces the generation of safety misadventure.
