Abstract
The utility model relates to a visual device for crane drivers. The visual device is fixed on the side surface at the end of an armed lever of a crane through a hanging scroll, and a device box is hinged on the hanging scroll through a through hole on a connecting lug; an image pick-up step-down transformer, a focusing camera and a wireless transmitter are arranged in the device box; and an elevation indicating lamp switch is connected with the image pick-up step-down transformer to form an image pick-up part. A displaying part comprises a switch, a displaying step-down transformer, a wireless receiver and a display, wherein the switch is connected between a working lamp power source and the displaying step-down transformer through electrical conductors. The image pick-up part and the displaying part respectively carry out wireless transmission and wireless receiving. The switch, the displaying step-down transformer, the wireless receiver and the display are installed in an operation chamber through a fixed plate. The camera freely swings along with the device box under the action of gravity, and a lens always faces to an operating surface. The utility model has the advantages of simple structure and high practicability; a driver can independently finish the hoisting operation by viewing the display; and when the visual device for crane drivers is used, safety hazards can be eliminated, and the work efficiency can be improved.
Description
Technical field
A kind of video unit, particularly a kind of visual device that is installed in the crane operator on the crane.
Background technology
Crane is when operation, the driver often can't see the particular location that the article that hang hang or the correct position of article landing, usually by crane man make a gesture, flute or command repeatedly with interphone and to face upward armed lever, the armed lever that falls, left and right sides pivoted arm bar, play rope, put rope and just can carry out operation.Even especially when many obstacles various visual angles, there are several commander workers also often to occur tiltedly drawing other dragging, break potential safety hazards such as article, make lifting operation not meet operation or work standard.
Summary of the invention
The purpose of this utility model provides a kind of visual device of crane operator.Use the visual device of this crane operator, need not many people command, the driver watches the details of lifting job by telltale in the crane chamber, finish crane lifting service by the lifting standard.
The purpose of this utility model can realize.The visual device of crane operator of the present utility model is made up of shooting and demonstration two parts.It is characterized in that camera part is made of hanging scroll, device box, absolute altitude indicator light switch, cameras with fixed focus, shooting reducing transformer, wireless launcher and electrical lead.Hanging scroll is fixed on the side, termination of crane armed lever, and device box is hinged on the hanging scroll by the through hole on the lug.Shooting reducing transformer, cameras with fixed focus and wireless launcher are installed in the device box.The absolute altitude indicator light switch is connected with the shooting reducing transformer.Device box has a center of turn on hanging scroll.Device box is under self-gravity action, and open ports one end is vertically towards ground.The line of centers of finding a view of cameras with fixed focus is parallel with the line of centers of two lifting cable wires and align the scope of operation.The display part is made of switch, demonstration reducing transformer, wireless receiver, telltale and electrical lead.Switch is connected between working lamp power supply and the demonstration reducing transformer through electrical lead.Switch, demonstration reducing transformer, wireless receiver and telltale are installed on the car body at operator's compartment windshield place by adapter plate.The camera part wireless transmission, the display part wireless receiving.
The visual device of crane operator of the present utility model is simple in structure, and is easy to use, practical.By artificial commander's puzzlement, reduce number of work when using it to remove crane operator work, eliminated potential safety hazard, improved work efficiency and standard.
Description of drawings
Provide embodiment of the present utility model below by accompanying drawing.
The visual device scheme of installation of Fig. 1, crane operator.
The A of Fig. 2, Fig. 1 is to view (display part scheme drawing)
The B of Fig. 3, Fig. 1 is to view (scheme of installation in device box and the box).
1 crane, 2 armed levers, 3 hanging scrolls, 4 lugs, 5 device boxes, 6 electrical leads, 7 shooting reducing transformers, 8 cameras with fixed focus, 9 wireless launchers, 10 show reducing transformer, 11 wireless receivers, 12 telltales, 13 windshields, 14 car bodies, 15 adapter plates, 16 switches, 17 absolute altitude indicator light switch, 18 cable wires among the figure.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3.The visual device of crane operator of the present utility model is made up of shooting and demonstration two parts.Camera part is made of hanging scroll 3, device box 5, absolute altitude indicator light switch 17, cameras with fixed focus 8, shooting reducing transformer 7, wireless launcher 9 and electrical lead 6.Hanging scroll 3 is fixed on the side, armed lever 2 termination of crane 1, and device box 5 is hinged on the hanging scroll 3 by the through hole on the lug 4.Shooting reducing transformer 7, cameras with fixed focus 8 and wireless launcher 9 are installed in the device box 5.Absolute altitude indicator light switch 17 is connected with shooting reducing transformer 7.Device box 5 has a center of oscillation on hanging scroll 3.Device box 5 can freely swing under self-gravity action, and the opening end that makes device box is not subjected to the influence of armed lever 2 landing angles variation always vertically towards ground.The line of centers of finding a view of cameras with fixed focus 8 is parallel with the line of centers of two lifting cable wires 18 and align the scope of operation.The display part is made of switch 16, demonstration reducing transformer 10, wireless receiver 11, telltale 12 and electrical lead 6.Switch 16 is connected between working lamp power supply and the demonstration reducing transformer 10 through electrical lead 6.Switch 16, demonstration reducing transformer 10, wireless receiver 11 and telltale 12 are installed on the car body 14 at operator's compartment windshield 13 places by adapter plate 15.The camera part wireless transmission, the display part wireless receiving.
Before the work, crane operator enters operator's compartment, at first moves absolute altitude indicator light switch 17 and switch 16, and shooting reducing transformer 7 and demonstration reducing transformer 10 are switched on respectively, and export 12V voltage respectively, make cameras with fixed focus 8, wireless launcher 9, wireless receiver 11 and telltale 12 energising work.After telltale 12 work, crane operator gets final product a people and carries out lifting work in the face of telltale 12.
The visual device of this crane operator is applicable to the apparatus of various lifting operations, for example building tower crane, industrial gauntry crane or the like.
