Description
Technical field
The utility model relates to the weight-lifting equipment field, relates in particular to a kind of hanging device that is used for roof or roof.
Background technology
The cleaning of high building glass curtain wall at present generally needs the cleaner to utilize rope to be hung in the outdoor aloft work of carrying out, and is begun by the top in building, cleans from top to bottom, and its labour intensity is big, inefficiency, cleaning very complicated and being absolutely unsafe.The hanging device safety performance of existing cleaning device is not high, and in a single day the position of center of gravity changes, and forms oblique pulling with regard to hanging device, causes skewing of hanging device easily, has potential safety hazard; And the hanging device of cleaning device need often can't be transported to roof because hanging device takes up room big in the roof operation, causes using the curtain wall cleaning device to carry out automated job.
The utility model content
Technical problem to be solved in the utility model is: a kind of arm beam of steelyard formula hanging device is provided, with the stability and the safety of raising equipment, and is convenient to use at roof or roof.
For solving the problems of the technologies described above, the technical solution of the utility model is: arm beam of steelyard formula hanging device comprises base; By the rotary table that engine installation drives, described rotary table rotates and is installed on the described base; Sinker, described sinker are slidingly mounted on the described rotary table; A secondary herringbone door frame that is oppositely arranged, described herringbone door frame comprises bracing frame and expansion bracket, and support frame as described above is articulated on the described rotary table, and support frame as described above is provided with axially extended chute; Described expansion bracket one end is articulated on the described rotary table, the other end be slidingly connected in the described chute; The swing door frame, described swing door frame is arranged between the described one secondary herringbone door frame and is hinged with support frame as described above; The lifting arm, described lifting arm is articulated on the described swing door frame, and described lifting arm one end is provided with fixed pulley, and the other end and described sinker are hinged; Winding plant, described winding plant are fixedly installed on the described sinker and by flexible cable and are connected with described fixed pulley.
As a kind of improvement, described lifting arm comprises that some joints are sleeved on telescopic boom together.
As a kind of improvement, described expansion bracket comprises first hydraulic ram.
As a kind of improvement, be hinged with swing arm on the support frame as described above, the transition pulley is installed in the described swing arm.
As a kind of improvement, described base is provided with feet, and described feet is provided with height adjuster.
As a kind of improvement, described base is provided with castor.
Owing to adopted technique scheme, the beneficial effects of the utility model are: because the miter gate sets up and counts bracing frame and the expansion bracket form that is articulated in respectively on the rotary table, when expansion bracket bounces back, slide block in the chute is to lower slider, the herringbone door frame just can fall, dwindle the occupation of land space of hanging device, be convenient to carrying; When expansion bracket stretched out, the sinker reach made the elevation angle of lifting arm become big, is unlikely to be stopped and the curtain wall cleaning device that can't hang down by the advertising panel of roof or glass curtain wall, has expanded the range of use of hanging device; Because arm beam of steelyard formula hanging device is provided with the swing door frame that is articulated in the herringbone door frame, the lifting arm is articulated on the swing door frame, in hoisting process, the swing door frame always keeps state straight down, stablized the center of gravity of hanging device, improved the stability of hanging device, be unlikely to make the hanging device overbalance and skew.
Because the lifting arm is designed to telescopic structure, makes hanging device when the roof operation, has enlarged scope of work.
Owing to be hinged with swing arm on the bracing frame, the transition pulley is installed in the swing arm, the power that acts on the lifting arm when making hanging device work obtains decomposing, and has improved safety performance.
Because base is provided with height adjuster, make hanging device levelling easily, also can use at the roof of surface irregularity.Because base is provided with castor, is convenient to arm beam of steelyard formula hanging device and moves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that scheme drawing is looked on Fig. 1 left side;
Among the figure: 1, bracing frame, 2, swing arm, 3, the lifting arm, 4, second hydraulic ram, 5, winding plant, 6, sinker, 7, turning motor, 8, base, 9, adjust screw rod, 10, castor, 11, rotary table, 12, first hydraulic ram, 13, fixed pulley, 14, the swing door frame, 15, counterweight.
The specific embodiment
As depicted in figs. 1 and 2, a kind of arm beam of steelyard formula hanging device comprises base 8; Rotary table 11 rotations that driven by turning motor 7 are installed on the base 8, and the output axle head of turning motor 7 is equipped with the gear mesh of gear and rotary table 11 outside faces, drive rotary table 11 and rotate, and adjust the position of the curtain wall cleaning device of lifting; Rotary table 11 is provided with sinker 6, and sinker 6 slides on the track of rotary table 11, is installed with winding plant 5 and counterweight 15 on the sinker 6; A secondary herringbone door frame that is oppositely arranged, the herringbone door frame comprises bracing frame 1 and expansion bracket, and bracing frame 1 bottom-hinged is on rotary table 11, and bracing frame 1 is provided with axially extended chute, is slidingly fitted with slide block in the chute; Expansion bracket is that first hydraulic ram 12, the first hydraulic rams, 12 bottoms and rotary table 11 are hinged, and the first hydraulic ram bar and slide block are hinged, when first hydraulic ram, 12 retractions, the herringbone door frame just can fall on rotary table 11, becomes accordion structure, it is little to take up room, and is convenient to carrying; When first hydraulic ram 12 stretches out, with bracing frame 1 jack-up, make sinker 6 move forward, the elevation angle of lifting arm 3 becomes big, is unlikely to be stopped and the curtain wall cleaning device that can't hang down by the advertising panel of roof or glass curtain wall; Be provided with swing door frame 14 between the one secondary herringbone door frame, the upper end and the bracing frame 1 of swing door frame 14 are hinged, the lower end is hinged with the middle part of lifting arm 3, the lower end and the sinker 6 of lifting arm 3 are hinged, swing door frame 14 always keeps state straight down in hoisting process, stablized the center of gravity of hanging device, improved the stability of hanging device, be unlikely to make the hanging device overbalance and skew.
Be hinged with swing arm 2 on the bracing frame 1, the transition pulley is installed in the swing arm 2, when needs are done the time spent, swing arm 2 is opened, by strut bar or locating dowel pin location, flexible cable one end is fixed on the elevator cylinder of winding plant, is connected by the fixed pulley 13 of transition pulley with lifting arm 3 tops, has decomposed the application force that acts on the lifting arm 3; When needs were carried, swing arm 2 was regained, and reduces to take up an area of the space.
