Abstract
The utility model relates to a reliable safety lift-type projection lighthouse, comprising a lighthouse body, a light bracket, a lift mechanism, a distribution box and a power supply contact mechanism. An ascending limit switch which is arranged at the top part of the light house body is connected in series with a lift mechanism control circuit; the light bracket which ascends to the top of the lighthouse can automatically stop ascending; the light bracket can be grounded when the light bracket descends to the bottom of the lighthouse, so that induced electricity can be effectively eliminated; a static contact with a caliper-shaped cross section is matched with a moving contact with an L-shaped cross section, so that a contact surface can be big, and the matching can be tight. The lighthouse has the advantages of convenient and safe operation, and can be used for large-area light in station yards, freight yards, whares, squares, etc.
Description
The utility model belongs to the large area lighting apparatus field, particularly a kind of safe and reliable lift projection lighthouse.
The beacon that uses at present roughly is divided into three kinds: first kind is integral solder formula beacon, exist big, stupid, heavy, installation difficulty is big, intensity is low, shortcomings such as operating maintenance inconvenience; Second kind is bolt interconnection system beacon, and it is big that it has solved installation difficulty, the shortcoming that intensity is low, but have operating maintenance inconvenience, shortcoming that the safety guarantee coefficient is low; The third is the lift beacon, have manually, torch is moving etc., substantially solved the shortcoming of preceding two kinds of beacons, but because himself structure or parts is unreasonable, in electric railway and defeated when becoming station and high wind area and using, some problems occur at secure context: first lift beacon is infinite place mechanism when in use lamp bracket rises to cat head, and whether operating personnel need face upward head and observe and feel to rise and put in place, whether decision stops to rise then, and operation is inconvenience very; Its two, do not have special earthing or grounding means, the sensed static of operating personnel often takes place touch condition of the injury condition; The design of its three power contact head is unreasonable, or manufacture difficulty is big, poor reliability, cisco unity malfunction under powerful wind-force, accident such as often take place that the power contact head sparking is burnt.
The utility model purpose is to provide lift projection lighthouse a kind of easy to use, safe and reliable.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: safe and reliable lift projection lighthouse, comprise body of the tower, lamp bracket, elevating mechanism, distribution box and power contact head mechanism, power contact head mechanism is made up of static contact mechanism that is installed on body of the tower and the dynamic contact mechanism that is installed on the lamp bracket, also have a rising limit switch to be serially connected with in the elevating mechanism control circuit at the body of the tower top, after lamp bracket rose to cat head, dynamic/static contact and joins, lamp bracket bumped out limit switch, and elevating mechanism stops action.
It is equipped with the automatic earthing or grounding means of an antistatic, and this device is by being loaded on moving contact 3 on the lamp bracket, forming with static contact 4 and ground connection connecting line that the body of the tower bottom links to each other with support by cushion pad.
Insulation board and fixture that dynamic contact mechanism is fixed on the lamp bracket by moving contact 1, moving contact 1 are formed, and it is approximate L shaped that moving contact 1 section is; Static contact mechanism by static contact 2, static contact 2 be fixed to insulation board on the lamp bracket and fixture and protective cover form, static contact 2 sections are approximate to be clamp shape.
Traversing static contact 2 middle and upper parts has the reinforcement screw rod, is provided with reinforcement spring between bolt and static contact biside plate on the screw rod.
The body of the tower top is provided with a rising limit switch in the utility model, this switch series is connected in the elevating mechanism control circuit, when lamp bracket rises to cat head, when being located at moving contact 1 on the lamp bracket and joining with the static contact 2 of being located at top of tower, lamp bracket bumps out the rising limit switch, the elevating mechanism control circuit disconnects, and rises to stop automatically, and is easy to use; Owing to be provided with the automatic earthing or grounding means of antistatic, when lamp bracket dropped to tower bottom, the automatic ground connection of lamp bracket was eliminated static, thereby has been guaranteed safety easy to maintenance; The moving contact 1 of being located at the static contact 2 of cat head and being located on the lamp bracket adopts clamp shape and L shaped plate fit form, and is simple in structure, contacts, and the protective cover in the static contact mechanism can play rainproof, dustproof effect, uses more safe and reliable.
Fig. 1 is the utility model structural representation;
Fig. 2 is the automatic earthing or grounding means structural representation of antistatic;
Fig. 3 is a power contact head mechanism structure schematic diagram among the embodiment 1;
Fig. 4 is a power contact head mechanism structure schematic diagram among the embodiment 2.
Further specify the utility model below in conjunction with accompanying drawing by embodiment.
Embodiment 1, and in the present embodiment, the lift projection lighthouse comprises body of the tower 5, lamp bracket 6, elevating mechanism, distribution box 7, power contact head mechanism 8, cat ladder 9, protective door 10.Elevating mechanism comprises motor 11, assembly pulley 12, revolution steel wire rope 13, counterweight stone roller 14 and control circuit, and last ceiling switch 15 is installed on the body of the tower top and is serially connected with in the elevating mechanism control circuit.This beacon also has the automatic earthing or grounding means 16 of an antistatic, the static contact 4 that it comprises the moving contact 3 be located on the lamp bracket, links to each other with body of the tower 5 bottoms by cushion pad 17, support 18 and set bolt 19, ground connection connecting line 20 1 ends are connected in static contact 4, and the other end links to each other with body of the tower 5.Power contact head mechanism is made of with the static contact mechanism that is loaded on top of tower the dynamic contact mechanism that is loaded on the lamp bracket 6.Dynamic contact mechanism is made up of approximate L shaped moving contact 1, insulation board 23, the fixture 24 of section; Static contact mechanism is made of static contact 2, insulation board 25, fixture 26 and the protective cover 27 that section is approximately clamp shape.Moving contact 1 is used with quiet 2.32 is the basis that links to each other with beacon.33 is lightning rod.
Its lifting working procedure is as follows: when desire rises, press distribution box rising button, elevating mechanism starts, and lamp bracket 6 rises, and when rising to cat head, bumps out rising limit switch 15, and elevating mechanism stops action automatically, and upward stroke is finished.While moving contact 1 and static contact 2 closures, light power is connected.When desire descends, press distribution box decline button, elevating mechanism starts, and lamp bracket 6 descends, and moving contact 1, static contact 2 are separately.When reducing at the bottom of the tower, press stop button, descending stroke is finished.Simultaneously moving contact 3 contacts with static contact 4 on the automatic earthing or grounding means 15 of antistatic and makes lamp bracket ground connection, the induced electricity on the elimination lamp bracket on the lamp bracket 6.
Embodiment 2, and in the present embodiment, traversing static contact 2 middle and upper parts has one to strengthen screw rod 28, is provided with reinforcement spring 30 between bolt 29 and the static contact biside plate on the screw rod.Security reliability is stronger in the use.Other is with embodiment 1.
