Description
Technical field
The present invention relates to a kind of crane for electric power tower, belong to power transmission and transformation field.
Background technology
Carrying out in erection construction to high-voltage power transmission tower at present, because therefore it need raw material to be transported to high-altitude by weight-lifting equipment highly comparatively greatly, and at present because without and electric force pole tower to construct matching used wherein equipment, therefore usually in construction, the equipment such as goliath are adopted, but goliaths etc. need to take larger place resource in use, therefore cannot use in the area that the such as workyard such as mountain region is less, simultaneously, its use cost is also relatively high, therefore the problem that many uses are inconvenient and construction cost is too high is caused, and when the equipment such as goliath cannot be used, workmen is then often needed to rely on manpower to carry out raw material lifting transport, working strength is huge and efficiency is not high, the constructions such as the construction maintenance of electric force pole tower are had a strong impact on.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, provides a kind of crane for electric power tower.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of crane for electric power tower, described crane for electric power tower is by undercarriage pan, pillar stiffener, lifting arm and strengthening beam are formed, described pillar stiffener and undercarriage pan upper surface are bolted, described pillar stiffener is at least made up of double sectioned column body and is bolted, cylinder is hollow cylinder type structure, mounting flange is established at its middle column body two ends, the uniform strengthening parallel with column axis of cylinder inside face is protruding, described strengthening convex cross section is arc, cartridge outer surface local is at least provided with four hinge holes, described strengthening beam is made up of at least two hold-down arms, wherein hold-down arm one end is hinged and angle is 15 °-120 °, described strengthening beam hold-down arm pin jointed end and cylinder hinge hole hinged, the hold-down arm other end is connected with electric force pole tower, described lifting arm is hydraulic telescopic arm, bracing wire support wheel is established in lifting arm upper surface front end, rear end establishes twisted wire to take turns and actuating device, actuating device is taken turns with twisted wire and is connected, twisted wire wheel separately establishes bracing wire, and bracing wire is by naturally drooping after support wheel, suspension hook is separately established in bracing wire front end, described lifting arm is separately connected with cylinder by steering hardware.
Steering hardware is by drive motor, driven wheel and turn to fluted disc to form, and wherein driven wheel is connected with drive motor and engages with turning to fluted disc.
Hold-down arm cross-sectional plane is rectangle, triangle or ellipse.
Stability Analysis of Structures of the present invention is light, and more traditional weight-lifting equipment place adaptive capacity is stronger, coordinates tightr, can reduce the labour intensity of construction cost and workmen greatly, and improve construction quality and efficiency with site operation.
