Abstract
The utility model provides a lamp post unfolding and folding device. The lamp post unfolding and folding device comprises a motor, a hollow screw sleeve, a lifting screw and lamp post arms which are symmetrically installed on the two sides of the top end of the lifting screw, wherein an output shaft of the motor is connected with the lifting screw and drives the lifting screw to rotate, the startup/shutdown of the motor is controlled by a switch, supporting rod groups are symmetrically installed on the two sides of the lifting screw, each supporting rod group consists of a plurality of supporting rods which are hinged at the end part, the upper ends of the supporting rod groups are fixed with the hollow screw sleeve, the lower ends of the supporting rod groups are fixed with the lifting screw, the ends at other positions on the supporting rod groups can move and form a straight line along with the upper end and the lower end under the drive of the motor. By using the lamp post unfolding and folding device provided by the utility model, a lamp post can be automatically unfolded/folded under the control of the motor, the horizontal projection area is reduced and equipment maintenance can be performed without causing collision.
Description
Technical field
The utility model relates to flight-aid corollary equipment technical field, and flight-aid light units field especially, in particular to a kind of lamp stand closing device.
Background technology
Flight-aid beacon equipment is often erected on very high steel tower at present, these steel towers high to tens meters even over hundred meters, the light units that navaid is used adds on the lamp stand of being located at horizontal spreading, for ease of maintenance, these lamp stands need to utilize jacking equipment from steel tower top, to drop to steel tower bottom and safeguard.These lamp stands are one or two straight-bars of horizontal spreading normally, and during jacking equipment operation, (in rising and decline process) can, because its horizontal projected area is compared with bumping greatly, be not easy to descending operation.If lamp stand is done too littlely, do not have again navaid effect.
Based on this, inventor of the present utility model utilizes knowledge accumulation and the experience of oneself, concentrates on studies and tests, and proposes a kind of lamp stand closing device, solves the collision problem of lamp stand and steel tower in above-mentioned descending operation process.
Utility model content
The utility model object is to provide a kind of lamp stand closing device, makes lamp stand under motor control, automatically open/to close up, and reduces its horizontal projected area, to carry out plant maintenance, can not bump.
Above-mentioned purpose of the present utility model realizes by the technical characterictic of independent claims, and dependent claims develops the technical characterictic of independent claims with alternative or favourable mode.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
A kind of lamp stand closing device, comprise motor, hollow swivel nut, lifting screw and the symmetrical lamp stand arm that is arranged on both sides, lifting screw top, the output shaft of described motor is connected with described lifting screw and drives its rotation, described motor is controlled its start/stop by a switch, the bilateral symmetry of lifting screw strut group is installed, strut group forms by many struts and its end is hinged, the upper end of strut group and hollow swivel nut are fixed and its lower end and lifting screw are fixed, in strut group, the termination of other positions forms straight line with described upper end and lower end movingly under the driving of described motor.
Further, in embodiment, described motor is DC Brushless Motor.
Further, in embodiment, described strut consists of strut arm and hinged end.
In further embodiment, the overload protection trigger that described lamp stand closing device also comprises a current detection circuit and is attached thereto, the output of overload protection trigger is connected with described switch.
Further, in embodiment, a plurality of navaid illuminating lamps are installed on described lamp stand arm.
From above the technical solution of the utility model, the lamp stand closing device that the utility model proposes, can make lamp stand under motor control, automatically open/to close up, and reduces its horizontal projected area, to carry out plant maintenance, can not bump.Compared with prior art, its beneficial effect is:
1, use comparatively succinct structural design and simple selection, realized the automatic open-close of lamp stand, be conducive to the maintenance maintenance of lamp stand system, cost is low, and good economy performance has application value;
2, the automatic open-close of lamp stand not only facilitates when operation, also can greatly reduce the horizontal projected area of lamp stand, for lamp stand transportation is provided convenience;
3, under extreme weather (as hurricane, heavy snow etc.), lamp stand can be drawn in, reduce its wind-engaging, carry snow area, protect lamp stand and the light fixture above lamp stand.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment lamp stand closing device, and wherein lamp stand is open mode.
Fig. 2 is the structural representation of lamp stand closing device in Fig. 1 embodiment, and wherein lamp stand is rounding state.
Fig. 3 is that the position of Fig. 1 embodiment hollow core swivel nut and lifting screw coordinates installation diagram.
Fig. 4 is the installation site schematic diagram of strut group in Fig. 1 embodiment.
The specific embodiment
For more understanding enforcement of the present utility model, especially exemplified by specific embodiment and coordinate appended graphic being described as follows.
Fig. 1, Fig. 2 be the utility model one embodiment lamp stand closing device open with rounding state under structural representation, wherein, a kind of lamp stand closing device, comprise motor 1, hollow swivel nut 2, lifting screw 3 and the symmetrical lamp stand arm 4 that is arranged on lifting screw 3 both sides, top, the output shaft of described motor 1 is connected with described lifting screw 3 and drives its rotation, described motor 1 is controlled its start/stop by a switch, the bilateral symmetry of lifting screw strut group 5 is installed, strut group 5 forms by many struts 6 and its end is hinged, fixing and its lower end 5b of the upper end 5a of strut group and hollow swivel nut 2 fixes with lifting screw 3, in strut group, the termination of other positions forms straight line with described upper end and lower end movingly under the driving of described motor, as shown in Figure 2.
If Fig. 1,2 is in conjunction with as shown in Fig. 4, as preferred embodiment, described strut 6 consists of strut arm and hinged end.
On described lamp stand arm 4, a plurality of navaid illuminating lamps 7 can be installed, for flight-aid.
In conjunction with Fig. 1,2,3,4, motor 1 is controlled after startup by switch, drive with the direct-connected lifting screw 3 of its output shaft and rotate, because the up/down termination of strut group is separately fixed on hollow swivel nut 2 and lifting screw 3, therefore when lifting screw 3 is under the driving of motor 1 during with respect to hollow swivel nut 2 rise/fall, strut group 5 can be strut arm 6b rotation planar by the conversion of motion of lifting screw 3 above-below directions, thereby lamp stand arm 4 is opened or drawn in.
As preferred embodiment; the overload protection trigger (not shown) that this lamp stand closing device also comprises a current detection circuit (not shown) and is attached thereto; the output of overload protection trigger is connected with described switch; like this when lamp stand arm open or draw in place after (if in place after motor be rotated further and will cause electric current to be uprushed); trigger overload protection, thereby stop motor.
As preferred embodiment, described motor 1 is DC Brushless Motor.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, within not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
