The technical scheme that its technical problem that solves the utility model adopts is: adopt the main structure of slider-crank mechanism as 90-degree orientation rising and laying mechanism of lamp post, the weight of using heavy-duty spring to come balance lamppost epimere, the upset that keeps manually realizing like a cork 90-degree orientation rising and laying mechanism of lamp post.Simultaneously, establish safety door protection and lock structure, prevent that layman and wind, rain, snow from causing the misoperation of 90-degree orientation rising and laying mechanism of lamp post.The private cable passage is also established in 90-degree orientation rising and laying mechanism of lamp post inside, and 90-degree orientation rising and laying mechanism of lamp post in use all keeps good being electrically connected of street lamp.
The beneficial effects of the utility model are, adopt 90-degree orientation rising and laying mechanism of lamp post, street lamp special messenger attendant can single craft be placed to level with the 90 ° of upsets of predetermined safe direction when installing of lamppost epimere, and the attendant stands on the ground and can very easily road lamp be changed and safeguard; After finishing, the street lamp maintenance can very like a cork the upset of lamppost epimere be reset to vertical state again.Simultaneously when lamppost is subjected to the strong bump of external force, because of lamppost has been preset safe inversion direction (avoiding pavement, high building, electric wiring etc.), so the loss of personnel and property during minimizing accident to greatest extent.
The specific embodiment
Shown in Figure of description 2, adopt the main structure of slider-crank mechanism as 90-degree orientation rising and laying mechanism of lamp post, it is made up of main body (2), square lever arm (5), adjusting screw(rod) (7) under main body on the rising and laying mechanism (1), the rising and laying mechanism, realizes the level and the flip vertical of lamppost epimere.Lamppost therefrom is divided into two sections, main body on lamppost epimere and the rising and laying mechanism (1) is connected to a fixed, main body under lamppost hypomere and the rising and laying mechanism (2) is connected to a fixed, main body (2) is connected with pivot pin A (11) under main body on the rising and laying mechanism (1) and the rising and laying mechanism, main body on the rising and laying mechanism (1) is connected with pivot pin B (12) with square lever arm (5), square lever arm (5) is connected with pivot pin C (18) with adjusting screw(rod) (7), adjusting screw(rod) (7) inserts under the rising and laying mechanism in main body (2) circular hole, under it, refill regulating spring (6), and carry out pretension with two hex nuts (10).
Accompanying drawing 1 is this motion of mechanism sketch, and regulating spring among the figure (6) is a heavy-duty spring, the weight of its spring force energy balance lamppost epimere (0).When the street lamp operate as normal, the lamppost two sections are vertical state, this moment, 90-degree orientation rising and laying mechanism of lamp post also was straight configuration, the weight of lamppost epimere (0) is all born by main body under the rising and laying mechanism (lamppost hypomere) (2) by main body on the rising and laying mechanism (1), and regulating spring (6) only needs certain pretightning force can keep lamppost epimere (0) to be vertical state.When needs are safeguarded street lamp or lamppost or are overhauled, hand push lamppost epimere (0) overcomes the pretightning force of regulating spring (6) by artificial external force, break lamppost epimere (0) and keep vertical this state, main body on the rising and laying mechanism (1) is rotated to predetermined direction by pivot pin A (11), square lever arm (5) is around arc swing in the rotary course, drive adjusting screw(rod) (7) simultaneously and up slide along main body under the rising and laying mechanism (2) endoporus, regulating spring (6) produce after the weight of its spring force balance lamppost epimere (0) and the centre-of gravity shift by compression to upper pulling force.When main body on the rising and laying mechanism (1) during around pivot pin A (11) half-twist, square lever arm (5) and adjusting screw(rod) (7) are in line, the gravity of the spring tension of regulating spring (6) and lamppost epimere (0) reaches balance, and mechanism is stable state, and main body on the rising and laying mechanism (1) no longer continues rotation.When the maintenance personal safeguards or after maintenance finishes, only needs a people up praise the poised state that lamppost epimere (0) can be broken rising and laying mechanism, rising and laying mechanism up overturns and resets.When square lever arm (5) in the rising and laying mechanism and adjusting screw(rod) (7) once more during linear state, rising and laying mechanism reaches stable state, rising and laying mechanism stretches, and main body under lamppost epimere (0), the rising and laying mechanism (lamppost hypomere) (2) vertically combines as a whole, and street lamp can carry out work.
In order to keep 90-degree orientation rising and laying mechanism of lamp post to be vertical state, prevent that wind, rain, snow and amateur street lamp attendant manpower from causing 90-degree orientation rising and laying mechanism of lamp post to overturn, the heavy losses that cause personnel and property, the special lock mechanism that on 90-degree orientation rising and laying mechanism of lamp post, set.At first, 90-degree orientation rising and laying mechanism of lamp post when stretching with rollover states, in the mechanism square lever arm (5) all with adjusting screw(rod) (7) linearly, only square lever arm (5) lays respectively at different positions.Overturn in order to limit rising and laying mechanism, we are under the vertical state at 90-degree orientation rising and laying mechanism of lamp post, add lock mechanism on square lever arm (5), have only lock socket cap lock pin (15) to pull out after, square lever arm (5) could be shifted, and promptly rising and laying mechanism just can overturn.Lock mechanism is made up of main body (2) and square lever arm (5) under draw ring (16), socket cap lock pin (15), pinning spring (17), the rising and laying mechanism, socket cap lock pin (15) is inserted in pinning spring (17), main body (2) (square lever arm (5) side) stepped hole penetrates under the rising and laying mechanism again, main body (2) opposite side stretches out under the rising and laying mechanism, penetrates draw ring (16) again in socket cap lock pin (15) hole.Main body under the rising and laying mechanism (2) lockpin hole adopts the kidney slot structure, when lock is closed, draw ring (16) sinks to main body under the rising and laying mechanism (2), socket cap lock pin (15) stretches under the tension force of pinning spring (17) in square lever arm (5) the insurance keyhole, limit the displacement of square lever arm (5), guarantee that 90-degree orientation rising and laying mechanism of lamp post is vertical state always, thereby play the effect of lock.When 90-degree orientation rising and laying mechanism of lamp post is overturn, with hand draw ring (16) is pulled out and half-twist, draw ring (16) is spacing under rising and laying mechanism on the step of main body (2) the kidney slot outside, socket cap lock pin (15) withdraws from square lever arm (5) insurance keyhole, square lever arm (5) can be shifted, this moment, lock was an open mode, can be to the lamppost upkeep operation that overturns.
In order to prevent that amateur street lamp attendant from operating 90-degree orientation rising and laying mechanism of lamp post, also set the safety door protection mechanism.It rolls on pin (19), the rising and laying mechanism under main body (1), the rising and laying mechanism main body (2) and special-purpose hexagonal key by rising and laying mechanism protective cover (3), rising and laying mechanism door guard shield (4), hexagon socket countersunk flat cap head screw (13), E type jump ring (14), elasticity and forms.Straight pin of special embedding in the hexagonal counter sink is provided with counterbore accordingly on special-purpose hexagonal key end face in hexagon socket countersunk flat cap head screw (13).Rising and laying mechanism protective cover (3) is inserted in main body on the rising and laying mechanism (1), can do 180 ° of rotations around main body (1) on the rising and laying mechanism.Rising and laying mechanism door guard shield (4) rolls pin (19) with elasticity and is connected with main body (2) under the rising and laying mechanism, and rising and laying mechanism door guard shield (4) can roll pin (19) around elasticity and rotate up and down.When need keep in repair lamppost, holding special special-purpose hexagonal key by professional street lamp attendant outwards winding the hexagon socket countersunk flat cap head screw (13) on rising and laying mechanism door guard shield (4) and the rising and laying mechanism protective cover (3), strike with the hand and open laying mechanism door guard shield (4), rotate rising and laying mechanism protective cover (3) again to 180 ° of positions, open the rising and laying mechanism lock, can carry out turning operation 90-degree orientation rising and laying mechanism of lamp post.After the street lamp maintenance finishes, rising and laying mechanism protective cover (3) and rising and laying mechanism door guard shield (4) are resetted, screw corresponding hexagon socket countersunk flat cap head screw (13) with special-purpose hexagonal key and get final product.
In order to realize that 90-degree orientation rising and laying mechanism of lamp post does not influence being electrically connected of street lamp in use, spy's main body (2) under rising and laying mechanism is provided with special-purpose cable passage, all keeps the good electrical of street lamp to connect at any state of 90-degree orientation rising and laying mechanism of lamp post.
Accompanying drawing 3 is the assembling outline drawing of 90-degree orientation rising and laying mechanism of lamp post, and accompanying drawing 4 is the version after 90 ° of upsets of 90-degree orientation rising and laying mechanism of lamp post.
This cover 90-degree orientation rising and laying mechanism of lamp post is made up of 20 kinds of parts, comprising five kinds of aluminium casting products, heavy-duty spring and some metal processing pieces, as accompanying drawing 2 part thumbnails.
Operating procedure: the 90-degree orientation rising and laying mechanism of lamp post shown in the accompanying drawing 2 is installed between the lamppost two sections, turn on hexagon socket countersunk flat cap head screw (13) with special-purpose hexagonal key, be rotated down rising and laying mechanism door guard shield (4) then, screw out holding screw (20) with instrument, use hand to rotate rising and laying mechanism protective cover (3) again to this side of rising and laying mechanism door guard shield (4), pull again draw ring (16) with socket cap lock pin (15) pull out and rotate to 180 ° fixing, promote lamppost epimere (0) with hand to socket cap lock pin (15) direction, lamppost epimere (0) promptly slowly rotates around pivot pin A (11), overturns gradually 90 ° to be the level of state.After with road lamp replacing and maintenance end, oppositely up promote lamppost epimere (0) again, lamppost can slowly rotate returns original position, (16) 180 ° of reverse rotation draw rings reset socket cap lock pin (15) again, 90-degree orientation rising and laying mechanism of lamp post promptly is lockable, and this moment, the two sections of lamppost promptly became an integral body.At last, rotate rising and laying mechanism protective cover (3) and reset, the rising and laying mechanism door guard shield (4) that up closes screws front and back hexagon socket countersunk flat cap head screw (13) and holding screw (20), promptly finishes the replacing and the maintenance process of whole street lamp.
When 90-degree orientation rising and laying mechanism of lamp post is installed, can set 90 ° of flip horizontal directions of best safety of lamppost, it can avoid building, runway or pavement etc., creates convenient, fast, safe operating environment for the street lamp attendant.After lamppost was subjected to the violent bump of external force, 90-degree orientation rising and laying mechanism of lamp post was with breakage, and the lamppost epimere will overturn by predetermined 90 ° of flip horizontal directions of best safety.Because lamppost can only be damaged by secure side, and secure side has been avoided building, runway or pavement etc. when being provided with, thereby the personnel that cause after the accident and the loss of property have been reduced downwards.
