Abstract
A hoisting limiting device for a small crane of an overhead working truck comprises a truck body, a lifting arm, a folding arm, a hoisting crane, an infrared transmitting device and an infrared receiving device, wherein the lifting arm is arranged on the truck body; a work arm is movably hinged onto the lifting arm; a small hoisting crane is fixedly arranged at the end part of the work arm; the infrared receiving device is fixedly arranged on one side of the work arm; and the infrared transmitting device is fixedly arranged on the truck body. According to the hoisting limiting device disclosed by the invention, the defined control on the position of the folding arm can be realized and the safety of equipment for hoisting operation and personnel can be ensured.
Description
Technical field
The present invention relates to an a kind of lifting class vehicle lifting peace control setup, be specifically related to a kind of inhibiting device of aloft work dolly lifting appliance, belong to the altitude operation vehicle technical field.
Background technology
As everyone knows: small crane generally is installed on the workplatform of aerial platform, in order to allocate and transport some instruments or goods and materials, the load meeting of crane has certain impact to the stability of whole operating mechanism, vehicle itself, and the safety of operating personal consisted of directly threaten, so, have strict requirement for the position of two folding arms of aerial platform.At present, existing engineering truck when lifting operation, for the position control of two folding arms because the actv. safety control not being set, the method of general employing experience range estimation is determined the position of folding arm, this method is unreliable to some extent, so, still there is potential safety hazard.
Summary of the invention
The object of the invention is to: for the existing the problems referred to above of altitude operation vehicle, the invention provides a kind of telpher hoisting limit device of aerial working vehicle, satisfy the little security needs when weighing of slinging of aerial platform.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of telpher hoisting limit device of aerial working vehicle, it comprises car body, lift arm, folding arm, lifting crane, infrared transmitting device, infrared receiver, it is characterized in that: car body setting lift arm is installed, on lift arm, be hinged with actively working arm, working arm end position be mounted with the lifting dolly, side position at working arm is installed fixedly infrared receiver, is mounted with infrared transmitting device at vehicle body.The infrared ray that infrared transmitting device sends, can guarantee that folding arm allows infrared receiver just receive in the position that limits, infrared receiver is transferred to corresponding control system with signal after receiving infrared ray, thereby the position that reaches folding arm limits.
Beneficial effect: can be found out by principle of work of the present invention, prodigiosin of the present invention is enough realized the restriction control to the folding arm position, can guarantee equipment and the personal safety of lifting operation.
Description of drawings
Accompanying drawing is principle schematic of the present invention.
Shown in the figure: 1, car body; 2, lift arm; 3, working arm; 4, lifting crane; 5, infrared transmitting device; 6, infrared receiver.
The specific embodiment
A kind of telpher hoisting limit device of aerial working vehicle, it comprises car body (1), lift arm (2), working arm (3), lifting crane (4), infrared transmitting device (5), infrared receiver (6), car body (1) setting lift arm (2) is installed, on lift arm (2), be hinged with actively working arm (3), working arm (3) end position be mounted with the lifting dolly (4), side position at working arm (3) is installed fixedly infrared receiver (6), is mounted with infrared transmitting device (5) at vehicle body (1).The infrared ray that infrared transmitting device (5) sends can guarantee that working arm (3) allows infrared receiver just receive in the position that limits.
