Abstract

The utility model relates to a lifting lamp stand device, which uses a telescopic folding type structure composed of a square type steel pipe or a round type steel pipe which is made up of a plurality of subsections by a truss mode. A fixed pulley is fixed on each subsection, and a steel cable is orderly wound with each fixed pulley in series, and is tightly wound and fixed with a steel cable barrel which is driven by a motor to rotate with the same direction and the same speed to draw the steel cable, or to loosen the steel cable for lifting, or to shrink and fold the lamp stand device. The utility model can be arranged in a whole sinking type or a half sinking type according to the environments, can be shrunk and hidden at daytime without influencing the landscape, and can be lifted to a preset height for providing the illumination to surroundings at night. The maintenance and the repair of the utility model can be operated on ground, and the utility model has the advantages of convenience and safety.

Description

Lift lamp bracket device

Lift lamp bracket device relates to the lamp bracket device.

Have now and be located at the square, the excursion district, the lamp bracket of traffic route both sides all adopts the High-Pole Lamp frame usually, and the lamp stand top high at height is provided with lamp bracket, and lighting is installed, and the feasible illumination zone that is located at the lighting of eminence can be big as much as possible.Such High-Pole Lamp is erected at the scenic spot excursion district, especially is located near the ancient building owing to lack disguise, and can influence people's sight daytime, takes a photograph, and also destroyed the view of excursion district simultaneously.Equally, now in the city in order to set off the profile of building or structures in night, be provided with the light projector lamp bracket that many lighting arts use around it or more directly Projecting Lamps be fixed on the external wall of building or structures, so just hinder the appearance of the city and building or structures neatly with attractive in appearance.And the lamp bracket of this bareing is all inconvenient, dangerous to the maintenance and the maintenance of light fixture.

The purpose of this utility model is; Overcome the deficiency of above-mentioned lamp bracket, provide a kind of simple in structure, installation, easy to use, good concealment, the lift lamp bracket device of good illumination effect.

The utility model is to constitute like this; The lamp bracket device adopts square steel pipe or the round steel pipe made with the truss mode by some sections to constitute scalable superposition mode according to lighting requirement.Fixed pulley fixedly is equipped with in bottom at its uppermost sections, the top is provided with lighting, fixed pulley fixedly is equipped with in the top and the bottom that are positioned at the sections at middle part, at the top of beneath sections fixed pulley is housed fixedly, steel wire rope is gone here and there successively and is walked around each fixed pulley and be connected with two cable drums respectively.On the steel wire rope of uppermost sections bottom, be provided with anti-breaking device, at the inboard upper and lower elongation stopper and the decline stopping means of being provided with of beneath sections, with the maximum elongation that limits the lamp bracket device with descend and locate.Cable drum is done in the same way under the driving of driving machine, rotates with speed, when steel wire rope is pulled down, by the fixed pulley that is located on each section each sections progressively is promoted to desired height.When steel wire rope is progressively unclamped, utilize the deadweight of sections, sink gradually, the sections that meanwhile is in top in the sections of indentation its underpart, shrinks the location until whole sections gradually fully.

Advantage of the present utility model is; The lamp bracket device adopts flexible superposition mode, can be arranged on the lamp bracket device in the lamp well of below ground, does complete heavy formula setting or it is arranged on grove and has in the middle of the shelter, does the semi-underground setting.Lamp bracket device contraction on daytime is hidden in the lamp well or in the middle of the shelter, can influence the natural landscape of excursion district, the good looking appearance of the attractive in appearance and building of the appearance of the city.Rising from lamp well or shelter evening rises to desired height and illumination is provided or provides lighting art illumination for building for surrounding environment.The utility model can carry out high and low adjusting easily according to the needs to surrounding environment illumination, and to the maintenance of light fixture, repairing can be carried out on the ground, not only convenient but also safety.

Accompanying drawing is one of the utility model embodiment,

Fig. 1. the heavy full formula of the utility model is provided with schematic diagram;

Fig. 2. the steel wire rope string is around the fixed pulley schematic diagram.

The utility model will be further described according to above-mentioned accompanying drawing, the sections 1 that the lamp bracket device is made by truss structure, and sections 2, sections 6 constitutes.Sections 1 can contract and fold in the sections 2, and the sections 2 that has sections 1 can contract and fold in the sections 6, in the bottom of sections 1 fixed pulley 4 is housed fixedly, at its top lighting is set.Fixed pulley 4 fixedly is equipped with in top and bottom at sections 2, and at the top of sections 6 fixed installation fixed pulley 4, its bottom is fixed in the lamp well.Be respectively equipped with

stopping means

5,10 in sections 6 inside upper part and bottom.Steel wire rope 8 strings are walked around and are fixed on sections 1, sections 2, and the fixed pulley 4 on the sections 6 and two cable drums 7 are fastened.On the steel wire rope of sections 1 bottom, be provided with steel wire rope anti-breaking device 9.

When the utility model will rise, at first open cover plate 3, starter motor 11 then, and motor 11 drives two cable drums 7 and does in the same way, rotates with speed, spurs steel wire rope 8 downwards, and with sections 1, sections 2 is raised up to desired height to steel wire rope 8 gradually by fixed pulley 4.As continue to raise, because the effect motor 11 of stop 5 can quit work, cable drum 7 stops operating, this moment, the lamp bracket device was raised to the extreme higher position.During decline, motor 11 reverse drive cable drums 7 move up steel wire rope 8 to unclamp, and rely on the deadweight of sections to move down gradually, and sections 1 is gradually in the retraction sections 2, sections 2 is gradually in the retraction sections 6 at the same time, during stop 10 positions, because the effect of stop 10, motor 11 quits work in sections 2 is reduced to sections 6, cable drum 7 stops operating, this moment, the lamp bracket device was fully retracted in the lamp well, closed upper cover plate 3, and lamp bracket device contraction work is finished.
