Among the figure:
The specific embodiment
Core of the present invention is to provide a kind of control box illumination equipment that is applied to hoisting crane so that illumination is provided when the control box repair and maintenance is operated, thereby when improving operating efficiency effective control system repair and maintenance cost.Specify this embodiment below in conjunction with Figure of description.
Be without loss of generality, this embodiment with wheel crane as being that main body specifies.
Identical with prior art; This wheel crane does to comprise wheel undercarriage, the turntable of getting on the bus, be arranged on elevator on the turntable of getting on the bus, arm, luffing etc. and go up mechanism of car; Above-mentioned functions parts and prior art are identical; Specifically see also shown in Figure 1ly, this figure is the integral structure scheme drawing of the said hoisting crane of this embodiment.Such as, control cabin 20 rear portions are provided with control box 10 on the chassis, and this control box 10 please in the lump referring to Fig. 2, the figure shows the rigging position relation of control box 10 as the electric intermediate link that is electrically connected with turntable of crane cab.This control box 10 can and chassis control cabin 20 between adopt threaded fasteners to removably connect, being convenient to as required, integral demounting gets off to overhaul replacing.Its set inside has relay, elements such as insurance row, terminal row, is connected with electrical control between the following chassis control cabin with get on the bus each actuating unit on the turntable of foundation.Because those skilled in the art can realize the above-mentioned functions parts fully based on prior art, so this paper repeats no more.
To the control box illumination equipment that is applied to hoisting crane, hereinafter will combine Fig. 3 and Fig. 4 to set forth in detail; Wherein, Fig. 3 is the schematic circuit diagram of the control box of hoisting crane described in this embodiment illumination equipment, and Fig. 4 is the mounted inside scheme drawing of hoisting crane control box shown in Figure 3.
As shown in the figure, this hoisting crane control box illumination equipment comprises luminous element 11 and on-off element 12.Luminous element 11 wherein is arranged in the control box 10, is used for the illumination that provides the repair and maintenance operation process required; This on-off element 12 is serially connected with between power supply and the luminous element 11, and luminous element 11 place circuit turn-ons or outage are realized in cabinet switch element 12 switch operating positions as required.So be provided with, when needs carried out upkeep operation, 12 power supplies of cabinet switch element can be carried out effective lighting to control box 10 inside to inventing element 11, have improved the operability of control box repair and maintenance greatly.This luminous element 11 can be selected illuminating lamp for use, such as, electricity-saving lamp, filament lamp or LED lamp etc.
Further, when avoiding short circuit or power too high, electric current is excessive to influence element service life, can between this on-off element 12 and power supply, safety element 13 be set.This safety element 13 can be selected individual member for use, preferably is arranged in the control box 10.
Need to prove that aforementioned switches element 12 can be arranged in the control box 10, also can be arranged in the chassis control cabin 20, as long as satisfy the use needs all in the scope that the application asks for protection.Obviously, this on-off element 12 is arranged on and helps total arrangement and electric wiring management in the chassis control cabin 20 more.
In addition, on-off element 12 preferably is electrically connected with luminous element 11 through the control terminal 14 that is arranged in the control box 10.During the assembling wiring,, can realize that through control terminal 14 circuit connects, and has better operability according to the electric wire of confirming design length selection respective length.
The principle of work of the said hoisting crane control box of the utility model illumination equipment is following:
Working power is through behind the safety element 13, and through operating closed illumination equipment on-off element 12, circuit is connected, and power supply is supplied power thereby be implemented in luminous element 11 through control box 10 internal piloting terminals 14, and luminous element 11 is in running order; In like manner, if illumination equipment on-off element 12 is broken off in operation, control box 10 internal piloting terminals 14, luminous element 11 do not have electricity, thereby luminous element 11 is in off working state.
Because arrangements of elements such as relay, insurance row, terminal row are comparatively compact in the control box 10, and block each other, therefore, have the problem that influences the light coverage effect.Based on this problem; Can adopt swing arm 15 to connect illuminating lamp (luminous element 11); Swing arm 15 has certain flexibility, and in the actual use, the operator can freely swing to desirable position as required; Thereby make arbitrary element to be looked in the light coverage control case, reliable guarantee is provided for precisely carrying out upkeep operation reliably.Has better operability
As shown in Figure 4, illuminating lamp is connected with mounting seat 16 through swing arm 15, and this mounting seat 16 is captiveed joint with the top inner wall of control box 10 through threaded fasteners; Certainly, swing arm 15 can be adjusted the control position of illuminating lamp to a certain extent, and mounting seat 16 in fact also can be fixed on the side inner walls of control box 10.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
