The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, ascending/descending device for lamp apparatus of the present utility model comprise shell 1, control circuit (scheming not shown), wire spool 2, magnetic valve 3, for the motor 4 that drives wire spool 2 to rotate, for detection of optocoupler assembly 5 and the cable 6 of winding on wire spool 2 of wire spool 2 rotating speeds; Control circuit, wire spool 2, magnetic valve 3, motor 4 and optocoupler assembly 5 are all located in shell 1; The control end of the control end of magnetic valve 3, motor 4 and optocoupler assembly 5 are all connected with control circuit.One end of cable 6 is connected with control circuit, and it is outer for being connected with light fixture 8 that the other end stretches out shell 1; The outer peripheral edges of wire spool 2 are provided with a plurality of double wedges 21 that radially protrude, and double wedge 21 is uniformly distributed with respect to the center of wire spool 2; Magnetic valve 3 is positioned at the rear of wire spool 2, magnetic valve 3 is provided with telescopic motion bar 31, motion bar 31 is when stretching out state in the gap of block between described double wedge 21, when contraction state, the front end face of motion bar 31 is positioned at the rear of wire spool 2, wherein, described 'fornt', 'back' direction only represents the relative position relation between parts, the orientation independent in implementing with reality; When motion bar 31 is contraction state, magnetic valve 3 integral body are positioned at the rear of wire spool 2, not at same plane, do not affect the rotation of wire spool 2 with wire spool 2; When motion bar 31 is after stretching out state, motion bar 31 passes wire spool 2 place planes, and is stuck in the gap between double wedge 21, stops the continuation rotation of wire spool 2, thereby stops the liter of light fixture 8 or fall.
As shown in Figure 2, described motor 4 drives wire spool 2 to rotate by synchronous pulley; Described synchronous pulley comprise little synchronizing wheel 71, the large synchronizing wheel 72 being fixedly connected with wire spool 2 being arranged in motor 4 rotating shafts and be connected in little synchronizing wheel 71 and large synchronizing wheel 72 between synchronous belt 73.On described little synchronizing wheel 71, be fixed with reading dial 51; The periphery of described reading dial 51 is evenly provided with a plurality of reading teeth 52 that radially protrude, and between reading tooth 52, is provided with gap; The described optocoupler assembly 5 for detection of wire spool 2 rotating speeds comprises transmitting tube 53 and receiving tube 54, and reading dial 51 place planes are between transmitting tube 53 and receiving tube 54, and transmitting tube 53 is corresponding with reading Chi52 position with receiving tube 54 position.Transmitting tube 53 and receiving tube 54 are arranged on a circuit board, the signal of receiving tube 54 sends to control circuit by this circuit board, when reading tooth 52 blocks between transmitting tube 53 and receiving tube 54, receiving tube 54 does not receive optical signal output 0, when reading tooth 52 does not block receiving tube 54, receiving tube 54 outputs 1, thereby when reading dial 51 rotates with different rotating speeds, optocoupler assembly 5 can send to control circuit the signal of different frequency, this signal is square wave in theory, thereby the output of receiving tube 54 can be directly connected to control circuit, but there is other interference in actual use, therefore receiving tube 54 can be connected to control circuit by the circuit such as filter circuit that arrange on circuit board, it is more accurate to make to measure.When light fixture 8 is out of control while dropping, cable 6 can pull wire spool 2 to make overspeed rotation, and the motion bar 31 that control circuit is controlled magnetic valve 3 stretches out, and stops being rotated further of wire spool 2, thereby protection light fixture 8 does not drop.
Also comprise the second optocoupler assembly (scheming not shown) being connected with control circuit; Described the second optocoupler assembly comprises the second transmitting tube and the second receiving tube, and wire spool place plane is between the second transmitting tube and the second receiving tube, and the second transmitting tube is corresponding with double wedge 21 position with the position of the second receiving tube.The measuring principle of this second optocoupler assembly and above-mentioned optocoupler assembly 5 are similar; double wedge 21 serves as the effect with reading tooth 52 simultaneously; the second optocoupler assembly and above-mentioned optocoupler assembly 5 form two protection systems; when synchronous belt 73 fracture; even if little synchronizing wheel 71 rotating speeds are normal; but wire spool 2 remains fast and drops, therefore the second optocoupler assembly plays the second heavily effect of protection.Above-mentioned optocoupler assembly 5 can certainly be set and the rotating speed that the second optocoupler assembly is measured wire spool 2 is directly set, but because the radius of wire spool 2 is larger, double wedge 21Jian at least will reserve the width that can allow motion bar 31 pass through in gap, and therefore the rotating speed by double wedge 21 detection wire spools 2 can be lower than the sensitivity of surveying rotating speeds with reading dial 51.Should be noted that; the utility model is only to provide the apparatus structure that can realize this defencive function; using which kind of standard as the abnormal foundation of rotating speed; it not consideration category of the present utility model; in concrete enforcement; as long as the apparatus structure that the utility model adopting provides, opens magnetic valve 3 extremely thereby no matter which kind of standard to be judged as rotating speed with, within all should being included in the utility model.
As shown in Figure 3, described wire spool 2 comprises shroud 22 and the hub disk 23 being in transmission connection with motor 4, and shroud 22 is fixedly connected with hub disk 23; Between cable 6 windings and shroud 22 and hub disk 23, form in side winding slot; Described double wedge 21 is arranged on shroud 22, and double wedge 21 outer end is also provided with the folded up portion 24 of turning up forward, makes cable 6 be not easy dislocation and reels.Wire spool 2 is also provided with electrodeless slip ring 25, and one end that described cable 6 is connected with control circuit is arranged on this electrodeless slip ring 25 and by electrodeless slip ring 25 and is electrically connected to control circuit.In the present embodiment, electrodeless slip ring 25 is located at the central authorities of hub disk 23, after the end of cable 6 and electrodeless slip ring 25 install, fixing by subterminal part and hub disk 23 cable 6, when wire spool 2 is rotated, cable 6 can be along wire spool 2 take-ups or unwrapping wire, and the wire of the end of cable 6 can not reel and loop under the effect of electrodeless slip ring 25, not frangibility.For other forms of wire spool, the change that the mounting means of electrodeless slip ring 25 can adapt.
The bottom of described shell 1 is provided with the through hole that current supply cable 6 passes, and cable 6 is directly passed by bottom, the lift adjustment of more convenient light fixture 8, and through hole also can be opened in other sides of shell 1 certainly, but need to install the devices such as pulley additional.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
