Abstract
The invention discloses an insulation arm for a crane in electricity operation, which comprises an outer arm base, an insulation outer arm fixedly connected onto the outer arm base, an insulation middle arm sleeved with the insulation outer arm, and an insulation inner arm adopting a hollow structure and sleeved with the insulation middle arm. The insulation arm also comprises a telescopic oil cylinder connected between the insulation outer arm and the insulation middle arm, the fixed end of the telescopic oil cylinder is mounted on the insulation middle arm, and the movable end of the telescopic oil cylinder is connected with the insulation outer arm; and the insulation inner arm extends and contracts in synchronization with the insulation middle arm through a lift-range rope system and a reverse-range rope system. Through the adoption of the structure, when the insulation arm is used in a place with intensive circuits, the range of high-altitude electric field is large, all that is needed for insulation protection is to lift the arm body, and the vehicle insulation level is 220 kV, which is higher than that of the common insulation vehicles. The insulation arm can meet the needs for large operating range and amplitude, greatly improves the safety performance of vehicles, meets the requirements for high-altitude operation under various insulation conditions, and can be applied to various industries such as insulation high-altitude equipment and insulation hoisting equipment.
Description
Technical field
The present invention relates to a kind of weight-lifting equipment parts of electric operating, specifically a kind of electric operating hoisting crane insulation arm.
Background technology
At present, along with the development of China's economic construction, more and more higher to electric power supply requirement, require to adopt hot line work mode to process electric power maintenance problem, reduce the economic loss of bringing because having a power failure.
The special-use vehicle of high-altitude maintenance is carried out in existing hot line work, all adopt insulation arm body structure: these traditional structures are with the vehicle of insulation arm body, because structure arranges unreasonable, be only applicable to opening, the operating environment that only has operation place to have electric field to exist is can meet insulating requirements under 110 kV at voltage conventionally.In transmission of electricity, power transformation circuit is comparatively concentrated, voltage is high, and while requiring vehicle to have larger scope of work and amplitude, existing insulation aloft work special-use vehicle arm body structure cannot meet the demands.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of job requirements that can meet larger scope of work and amplitude, improves the safety performance of vehicle and can be suitable for the electric operating hoisting crane insulation arm of the aloft work demand of multiple insulation operating mode.
In order to solve the problems of the technologies described above, electric operating hoisting crane insulation arm of the present invention, comprise outer arm pedestal, on outer arm pedestal, be fixedly connected with insulation outer arm, insulation outer arm inner sleeve has arm in insulation, and in insulation, arm inner sleeve has the insulation inner arm of hollow structure, also comprises that is connected to the telescopic oil cylinder between arm in the insulation of insulation outer arm, the fixed end of telescopic oil cylinder is arranged in insulation on arm, and the movable end of telescopic oil cylinder is connected with insulation outer arm; Insulation inner arm is by arm synchronization telescope in lift rope system and backhaul rope system and insulation.
In described insulation outer arm and insulation, arm is respectively arranged with roller between inner arm with insulating between arm and in insulation.
Described outer arm pedestal is made by steel material.
Adopt after above-mentioned structure, because insulation arm body is set to three joint straight-arm stretching structures, outer arm pedestal is that steel material is made, and the arm body of three joint straight-arms is insulation material; In insulation outer arm, insulation, arm is by telescopic oil cylinder drive actions, and the action of insulation inner arm is driven by synchronization telescope structure, adopts idler wheel mechanism to reduce the friction of arm body between arm body; In the concentrated place of circuit, use Shi， high-altitude electric field scope large thus, when arm body lifts, just can carry out insulating protection, arm body withstand voltage grade is high, and the vehicle class of insulation is 220 kV, higher than common insulation vehicle; Arm body intensity is high, and bending strength is large, and the biggest lifting capacity is large, can meet the job requirements of larger scope of work and amplitude, has greatly improved the safety performance of vehicle, again the aloft work demand of applicable multiple insulation operating mode; Applicable to multiple industries such as insulation altitude plant, insulation weight-lifting equipments.
Accompanying drawing explanation
Fig. 1 is the structural representation of insulation arm for electric operating hoisting crane of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, electric operating hoisting crane of the present invention is described in further detail with insulation arm.
As shown in the figure, electric operating hoisting crane insulation arm of the present invention is three joint straight-arm stretching structures, the outer arm pedestal 1 that steel material is made is connected with turntable and luffing hoist cylinder, can bear larger election power, make arm body do lifting and down maneuver, outer arm pedestal 1 is bolted to connection insulation outer arm 2, insulation outer arm 2 inner sleeves have arm 3 in insulation, in insulation, arm 3 inner sleeves have the insulation inner arm 4 of hollow structure, also comprise that is connected to the telescopic oil cylinder 5 between arm 3 in 2 insulation of insulation outer arm, the fixed end of telescopic oil cylinder 5 is arranged in insulation on arm 3, the movable end of telescopic oil cylinder 5 is connected with insulation outer arm 2, insulation inner arm 4 by lift rope be 6 with backhaul rope be 7 with insulation in arm 3 synchronization telescopes.
Further can be in insulation outer arm 2 and insulation arm 3 and insulate and be respectively arranged with roller 8, the friction while reducing arm body action between inner arm 4 between arm 3 and in insulation.
During use, insulation outer arm 2 is connected with arm 3 in insulation by telescopic oil cylinder 5, and under the driving of hydraulic power, in insulation, the relative insulation outer arm of arm 3 is done and stretched out (retraction) action.Insulation inner arm 4 is that 6(backhaul rope is 7 at lift rope) pulling under, do with insulate in synchronizeing of arm 3 stretch out (retractions) and move.When making expanding-contracting action, be arranged on roller 8 between the arm between arm body and can effectively reduce the friction between arm body, reduce to move resistance and avoid arm body to scratch.
