Abstract
The invention provides a lamp and cable follow-falling device, comprising a trolley body and a lifting rod, wherein the lifting rod is vertically and fixedly arranged on the trolley body; the lamp is fixedly arranged at the upper end of the lifting rod; the lamp and the trolley body are connected by a cable; the side wall of the trolley body is fixedly provided with a limiting piece through which the cable can penetrate; and the cable is provided with a cable weight positioned below the limiting piece. The lamp and cable follow-falling device provided by the invention has the advantages that when the lifting rod is lengthened, the lamp can be lifted to the needed height, so that large-area and high-brightness illumination is realized, simultaneously the cable also rises, and the cable is in a straightening state all the time under the gravity action of the cable weight; and when the lifting rod is retracted, the lamp falls together along with the lifting rod, so that the cable can not be bent or offset due to falling of the lifting rod, the accidents caused by the cable clamped at the connecting position of the lifting rod or other obstacles in the falling process are avoided.
Description
Technical field
The present invention relates to a kind of lamp cable with falling unit, the lamp cable that relates in particular to a kind of removable up-down beacon is with falling unit.
Background technology
Carrying on construction work at night, speedily carrying out rescue work, during occasion operation such as the disaster relief, needing the temporary light source equipment of large tracts of land, high brightness that illumination is provided.Settling mode at present commonly used is to set up beacon temporarily, and light fixture is installed, but that this method is not only built the cycle is long, and on-the-spot adaptive capacity is poor, and illuminator level, angular adjustment are difficult.
In order to overcome the defective of setting up beacon temporarily, existing a kind of removable up-down beacon has also appearred on the market, and it is raised to required height through elevating lever with light fixture, regulates very conveniently, and on-the-spot adaptive capacity is strong, so has obtained extensive use.But when needs were fallen light fixture, light fixture was along with elevating lever descends together, and the cable of light fixture can bending or skew take place when elevating lever reduces, and causes cable to be stuck in elevating lever junction or other barrier places, and then causes the accident, as crush cable.In order to address this is that, there is the catapult of use line to replace cable in the prior art, become to produce cost but adopt the catapult line to increase undoubtedly, but also the big problem of line drop is arranged.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of lamp cable, the phenomenon that it can avoid cable in elevating lever decline process, to be stuck or to crush with falling unit.
The present invention realizes like this; A kind of lamp cable is with falling unit; Comprise car body and be vertically located in the elevating lever on the said car body, said light fixture is fixedly arranged on the upper end of said elevating lever, connects through cable between said light fixture and the car body; Said car body sidewall is installed with one can hold the locating part that said cable passes, be slidingly equipped with on the said cable one be positioned at said locating part below cable weigh down.
Particularly, said cable weighs down and comprises that one slidably is arranged in the sash weight that the slip ring and on the said cable is connected with said slip ring.
More specifically, connect through a metallic rod between said slip ring and the sash weight, flexibly connect between said metallic rod and the slip ring, be fixedly connected between said metallic rod and the sash weight.
More specifically, said metallic rod upper end laterally activity is equipped with a lock pin, and said lock pin is fixedly connected with said slip ring, is fixedly connected by welding between said metallic rod and the sash weight, and perhaps said metallic rod and sash weight are one-body molded.
Perhaps, said cable weighs down and comprises that one slidably is arranged in the sash weight that the pulley and on the said cable is connected with said pulley.
Particularly, connect through a metallic rod between said pulley and the sash weight, flexibly connect between said metallic rod and the pulley, be fixedly connected between said metallic rod and the sash weight.
More specifically, said metallic rod upper end laterally activity is equipped with a lock pin, and said lock pin is fixedly connected with said pulley, is fixedly connected by welding between said metallic rod and the sash weight, and perhaps said metallic rod and sash weight are one-body molded.
Particularly, said cable upper end is connected with said light fixture through a lamp cable joint, and said cable lower end is connected with said car body through a car body cable joint.
Preferably, said elevating lever is the vapour-pressure type elevating lever, and said vapour-pressure type elevating lever comprises the metal tube and the cylinder of being located in the said car body of the mutual socket of more piece, connects through a safety cap between said each metal tube.
Further, said locating part is a ring-type or spherical, runs through on it to be provided with the through hole that supplies said cable to pass.
When elevating lever of the present invention extends, can light fixture be raised to required height, thereby realize the illumination of large tracts of land, high brightness, cable also rises thereupon simultaneously, and cable is in stretching state always under the action of gravity that cable weighs down; When elevating lever shrinks; Light fixture is along with elevating lever descends together; Cable also is in stretching state always under the action of gravity that cable weighs down; Therefore bending or skew can not take place because of elevating lever reduces in cable, thereby have avoided cable in the decline process, to be stuck in elevating lever junction or other barrier places and cause the accident.
