Abstract
The utility model discloses a dual-hinge point shakable elevator arm root device, comprising a straight girder, two diagonal web members, two upper planer diagonal web members and two connecting ear plates, wherein one end of each of two diagonal web members is respectively welded with two lower chord members; the other end is respectively welded with two ends of the straight girder; one end of each of two upper planer diagonal web members is mutually connected and welded with an upper chord member; the other end is respectively welded with two ends of the straight girder; the straight girder, the two diagonal web members and the two upper planer diagonal web members are welded to form a truss structure; and the two connecting ear plates are welded at two ends of the straight girder. The device is located at the root of an elevator arm; transition from an upper chord single hinge point of a triangular arm node into an upper chord dual-hinge points at the root of the arm is achieved; stable and reliable connection with a tower body is achieved; and the elevator arm can be safely and reliably waved upwards vertically. Thus, overall reduced demolition of an electric holding rod is achieved.
Description
Technical field
The utility model relates to a kind of two hinge swaying type crane arm arm root devices for the electric power pole, belongs to heavy-duty machine tool technical field.
Background technology
Up-small and down-big based on present electric power tower global sections, bore is more little when utilizing the electric power pole more up to adorn.Behind the intact electric power tower to be installed, the dismounting of electric power pole has just become a difficult problem, namely how flat arm is removed under the situation that does not have special-purpose lifting appliance.The flat arm section form of at present flat arm-type electric power pole has equilateral triangle formula and inverted triangle form.For the inverted triangle form, by removing flat arm roots lower boom list hinge bearing pin, utilize two hinges of flat arm roots top boom can realize 90 ° on flat arm on shake work, wait to shake carry out whole pole behind the flat arm again the joint operation falls.And for the equilateral triangle formula, remove the two hinge bearing pins of flat arm roots lower boom, utilize single hinge of flat arm roots top boom also can realize 90 ° on flat arm on shake work, but single hinge have stressed shakiness when having shaken jib, meet wind carry easily rock, local pressure is too concentrated and to the too high difficult problem that requires of making.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of simple in structure, safe and reliable two hinge swaying type crane arm arm root devices that are applicable to the two flat arm electric power poles of equilateral triangle are provided.
The technical scheme in the invention for solving the above technical problem is: the removable crane arm arm of this pair hinge root device is arranged on the arm root place of electric power pole crane arm, going up the plane diagonal web member by straight beam, two diagonal web members, two is connected otic placode and forms with two, one end of described two diagonal web members welds with two lower booms respectively, and the other end welds with the two ends of straight beam respectively; Described two ends of going up the plane diagonal web member interconnect and weld with top boom, and the other end welds with the two ends of straight beam respectively; Described straight beam, two diagonal web members and two last plane diagonal web member welding form truss structure.Arm root joint is connected with body of the tower by two steady failure-freies of hinge that wind up, and crane arm vertically can have been shaken safely and reliably.
The utility model the two ends of described straight beam respectively be provided with the connection otic placode.Connect otic placode and be used for being connected with body of the tower, two connect otic placode and make connection more firm.
The utility model compared with prior art has the following advantages: realize that by transition structure the single hinge transition of winding up by the A-frame arm joint is the two hinges of winding up of arm root place, is connected with body of the tower steadily reliable, connects stressed surely, chance wind carries and is not easy to rock.

The specific embodiment
Be described in further detail below in conjunction with the utility model of embodiment, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment: shown in Fig. 1 to 5, the two flat arm electric power poles of described equilateral triangle comprise mast 1, upper bracket 2, crane arm 3, amplitude variation trolley 4, suspension hook 5, pivoting support 6, undersetting 7, pole standard knot 8, girdle ring 9, lifting body 10, hoist rope 11, lifting mechanism 12, electric-control system 13, luffing steel rope 14, luffing mechanism 15 and torque controller 16.
Described in the utility model pair of hinge swaying type crane arm arm root device is arranged on the arm root place of crane arm 3, comprises that straight beam 20, two diagonal web members 18, two last plane diagonal web members 21 are connected otic placode 22 with two.One end of two diagonal web members 18 welds with two lower booms 19 respectively, and the other end welds with the two ends of straight beam 20 respectively; Two ends of going up plane diagonal web member 21 interconnect and weld with top boom 17, and the other end welds with the two ends of straight beam 20 respectively; Last plane diagonal web member 21, straight beam 20, diagonal web member 18 welding form stable truss structure, and two connect the two ends that otic placode 22 is welded on straight beam 20.
The described in the utility model pair of hinge swaying type crane arm arm root device carrying out crane arm 3 when shaking operation task, stressed shakiness when the single hinges of top boom 17 that overcome crane arm 3 connect, meet wind carry easily rock, defective that local pressure is too concentrated, improved whole stressing conditions and stability of structure greatly.
When receiving arm, earlier adjusting on the straight beam 20 that crane arms 3 make crane arm 3 two by hoist rope 11 connects otic placodes 22 and is connected with bearing pin with the body of the tower main body, two bearing pins below the dismounting arm root, by hoist rope 11 crane arm 3 has vertically been shaken again, carry out integral body again and fall the joint operation, thereby carry out the dismounting of pole.
In addition, need to prove, the specific embodiment described in this specification sheets, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
