Abstract
The utility model discloses a small-crane hoisting limiting device for an overhead working truck. The small-crane hoisting limiting device comprises a truck body, a lifting arm, a folding arm, a hoisting crane, an infrared emission device and an infrared receiving device, wherein the lifting arm is arranged on the truck body; a working arm is movably hinged to the lifting arm; a hoisting trolley is fixedly arranged at the end of the working arm; the infrared receiving device is fixedly arranged on one side of the working arm; and the infrared emission device is fixedly arranged on the truck body. By the small-crane hoisting limiting device, the position of the folding arm can be limited and controlled; and safety of hoisting equipment and safety of people can be guaranteed.
Description
Technical field
The utility model relates to an a kind of lifting class vehicle lifting peace control setup, is specifically related to a kind of inhibiting device of aloft work dolly lifting appliance, belongs 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 is consisted of directly threat, 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 due to 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 purpose of this utility model is: for the existing the problems referred to above of altitude operation vehicle, the utility model provides a kind of telpher hoisting limit device of aerial working vehicle, satisfies the little security needs when weighing of slinging of aerial platform.
The technical scheme that the above-mentioned purpose that realizes the utility model 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: arrange on car body lift arm is installed, be hinged with actively working arm on lift arm, end position at working arm is mounted with the lifting dolly, a side position at working arm is installed fixedly infrared receiver, is mounted with infrared transmitting device on car 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 utility model, the utility model prodigiosin is enough realized can guaranteeing equipment and the personal safety of lifting operation to the restriction control of folding arm position.
Description of drawings
Accompanying drawing is principle schematic of the present utility model.
Shown in 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), upper setting of car body (1), lift arm (2) is installed, be hinged with actively working arm (3) on lift arm (2), end position at working arm (3) is mounted with lifting dolly (4), a side position at working arm (3) is installed fixedly infrared receiver (6), be mounted with infrared transmitting device (5) on car 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.
