Abstract
A landing leg extending warning device for an automobile crane comprises a power source, a force taking linkage switch, a warning lamp and limiting switches arranged on the automobile crane and respectively controlled by each vertical landing leg, wherein the limiting switches are connected parallelly and then serially connected with the warning lamp, the force taking linkage switch and the power source. By means of the landing leg extending warning device , when the automobile crane is not jacked up for working, the limiting switch arranged on the vertical landing leg is turned off when some landing leg of the automobile crane stretches out by mistakes or is not drawn back timely, so that the warning lamp is lightened for warning, users can know whether the landing leg stretches out by mistakes or is not drawn back timely by observing the warning lamp, and the landing leg extending warning device is very convenient to use.
Description
Technical field
The utility model relates to the car hosit technical field, is specifically related to the flexible alarming device of automobile crane supporting leg.
Background technology
Car hosit is a kind of heavy wares be used to the weight that hoists, and supporting leg is its important component part, and existing car hosit generally includes four or five vertical leg.Car hosit if supporting leg mistake is stretched out or in time do not regain, causes following harm in the process of moving easily: cause 1, that car hosit is unbalance tumbles; 2, blow down pedestrian or other vehicle or object, cause the accident; 3, cause supporting leg, hydraulic ram to damage economic loss.
Summary of the invention
The technical matters that the utility model solves provides a kind ofly can send the device of caution when automobile crane supporting leg mistake is stretched out or in time do not regained.
The technical scheme that the utility model adopts is: the automobile crane supporting leg alarming device that stretches, comprise power supply, power taking gang switch, Warning light and be arranged at the limit switch of being controlled respectively by every vertical leg on the car hosit, each limit switch is connected in parallel, and is connected in series with Warning light, power taking gang switch, power supply after each limit switch parallel connection again.
The beneficial effects of the utility model are: use the utility model, car hosit is when lifting work not, if certain root supporting leg mistake of car hosit is stretched out or is not in time regained, Warning light lights and sends caution, namely just know whether have the supporting leg mistake to stretch out or not in time withdrawal, to use very convenient by observing Warning light.
Description of drawings
Fig. 1 is the structural representation of the flexible alarming device of the utility model automobile crane supporting leg.
Nomenclature: 1-limit switch A; 2-limit switch B; 3-limit switch C; 4-limit switch D; 5-limit switch E; The 6-Warning light; 7-power taking gang switch; The 8-power supply.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The example structure of the flexible alarming device of automobile crane supporting leg, as shown in Figure 1, comprise power supply 8, power taking gang switch 7, Warning light 6 and be arranged at the limit switch A1 that is controlled respectively by five vertical leg on the car hosit, limit switch B2, limit switch C3, limit switch D4, limit switch E5, limit switch A1, limit switch B2, limit switch C3, limit switch D4, limit switch E5 is connected in parallel, limit switch A1, limit switch B2, limit switch C3, limit switch D4, after the limit switch E5 parallel connection again with Warning light 6, power taking gang switch 7, power supply 8 is connected in series.
Car hosit is when lifting work, and power taking gang switch 7 is in off-state, and Warning light 6 all the time can be not shinny.Car hosit is when lifting work not, power taking gang switch 7 is in closure state, if certain root supporting leg mistake of car hosit is stretched out or is not in time regained, limit switch by this vertical leg control is closed, cause Warning light 6 to light and send caution, namely just know whether have the supporting leg mistake to stretch out or not in time withdrawal, to use very convenient by observing Warning light 6.
