Abstract
The utility model discloses a vision field extension device of a crane, which comprises a liquid-crystal monitor connected to an instrument table of a chassis driver's cab of the crane. A front end camera is connected to the right front part of the chassis driver's cab of the crane. A back end camera is connected to a right back tail lamp bracket of a crane chassis. A front end camera line bunch is connected between the front end camera and the liquid-crystal monitor. A back end camera line bunch is connected between the back end camera and the liquid-crystal monitor. A crane line bunch is connected between the monitor and the crane chassis. Thus, the vision field blind zone of the driver can be thoroughly eliminated and safety for the operation and the field transfer of a traveling crane can be ensured. The utility model has the advantages of high automatic performance, broad vision field, all-weather work and convenient installation, is regarded as the vision field extension device of the traveling crane and provides guarantee for the safety for traveling and field transfer.
Description
Technical field
The utility model relates to a kind of visual field of movable crane that is applicable to and expands device.
Background technology
Known by movable crane, especially hoister in large tonnage, because hoisting crane front end arm is huge, the assembly pulley volume of arm end is big, accessory device is many, the visual field of seriously blocking chaufeur when the vehicle road running, the rear of hoisting crane are owing to the hoisting device such as control cabin, clump weight, winch of getting on the bus on the car body, and chaufeur can't be observed by the dead aft that the rear window of operator's compartment be can't see side mirror when reversing.
Summary of the invention
The purpose of this utility model is to provide a kind of hoisting crane visual field to expand device, and can the make a clean sweep of blind area of chaufeur of this device guarantees the safety that movable crane travels and cuts to.
The purpose of this utility model is achieved in that this device comprises LCD monitor, LCD monitor is connected on the instrument desk of hoisting crane chassis operator's compartment, the front end camera is connected the right front of hoisting crane chassis operator's compartment, the rear end camera is connected on the right back tail light support on hoisting crane chassis, be connected with front end camera wire harness between front end camera and the LCD monitor, be connected with rear end camera wire harness between rear end camera and the monitoring device, be connected with the hoisting crane wire harness between monitoring device and the hoisting crane chassis.
LCD monitor is used for observing the expansion visual field at the place ahead or rear as the main interface of driver's seat expansion; The front end camera solves the visual field is blocked in the right front by crane arm, arm head sheave, rope etc. blind area; The rear end camera solves because the blocking of the hoisting device such as control cabin, clump weight, elevator of getting on the bus, the dead aft blind zone problem that can't can't see side mirror by the rear window of operator's compartment.
Forward visibility is expanded and the demonstration of back visibibility expansion at monitoring device, is to automatically switch by the astern signal of gathering movable crane, also can pass through button switch, remote controller manual switchover.
Can the make a clean sweep of blind area of chaufeur of the utility model guarantees the safety that movable crane travels and cuts to.The automatic performance height affords a wide field of vision, and all weather operation is convenient to install, and is easy to promote.Device is expanded in the visual field that can be used as movable crane, for the safety of travelling and cutting to provides safeguard.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model.
