Abstract
A kind of steel tower hydraulic lifting apparatus includes two foundation framves, suit expansion bracket in the chassis, pin hole is arranged at intervals on the chassis, expansion bracket, the corresponding lower supporting beam of chassis installation, corresponding expansion bracket installs supporting beam, first pulling plate and the second pulling plate in the upper supporting beam are set, hydraulic jack is set in the lower supporting beam.The present invention enables column foot to be promoted step by step by expansion bracket and the spaced pin hole of chassis, and the promotion of the larger stroke of column foot can be realized using only small-sized hydraulic jack, and few using tool, operating procedure is simple, substantially reduces the cost of electric power pylon repair.
Description
Technical field
The present invention relates to a kind of electric power pylon maintenance unit, more particularly to a kind of steel tower hydraulic lifting apparatus.
Background technology
Electric power pylon is often because of the reasons run-off the straight such as surface subsidence, since the big quality of steel tower volume is big, it is desirable to which righting need to make
Column foot is jacked up with large-scale lifting appliance or using hydraulic test.Lifting appliance is all big machinery, and the steel tower settled is big
In countryside or mountain area, scheduling transfer is time-consuming and laborious for many places, and when field condition complexity can not even construct；Hydraulic test is compared with lifting
Equipment volume is small, and difficulty of construction is lower, but hydraulic pressure lift space is limited, if Iron tower incline angle is larger, it is necessary to using large-scale
Hydraulic cylinder, and multi-cylinder operation is usually needed, it also needs to carry large number of equipment, considerably increases construction cost.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of steel tower hydraulic lifting apparatus.
The technical solution adopted by the present invention is：A kind of steel tower hydraulic lifting apparatus includes two foundation framves, the chassis inner sleeve
Expansion bracket is filled, pin hole, the corresponding lower supporting beam of chassis installation, corresponding expansion bracket peace are arranged at intervals on the chassis, expansion bracket
Supporting beam is loaded onto, the first pulling plate and the second pulling plate in the upper supporting beam are set, hydraulic jack is set in the lower supporting beam.
A kind of steel tower hydraulic lifting apparatus, it is characterized in that：Stabiliser bar arranged in a crossed manner between corresponding chassis.
A kind of steel tower hydraulic lifting apparatus, it is characterized in that：The upper support soffit setting is anti-to raise one's hat, under described
Support top surface of the beam setting anticreep pedestal.
The present invention enables column foot to be promoted step by step by expansion bracket and the spaced pin hole of chassis, using only small-sized hydraulic
The promotion of the larger stroke of column foot can be realized in jack, and few using tool, operating procedure is simple, substantially reduces electric power pylon dimension
The cost repaiied.Stabiliser bar can greatly improve the stability of chassis, effectively avoid sliding laterally, and anti-raise one's hat can have with anticreep pedestal
Effect avoids hydraulic jack from withstanding in lifting process sliding.
Description of the drawings
Fig. 1 is front view of the present invention；
Fig. 2 is left view of the present invention；
In figure：1- chassis, 2- expansion brackets, supporting beam under 3-, the upper supporting beams of 4-, 5- pin holes, the first pulling plates of 6-, the second pulling plates of 7-,
8- hydraulic jacks, 9- prevent raising one's hat, 10- anticreep pedestals, 11- fixedly connected holes, 12- mounting holes, 13- stabiliser bars.
Specific embodiment
Including two foundation framves 1, expansion bracket 2, the chassis, expansion bracket are set in chassis 1 for a kind of steel tower hydraulic lifting apparatus
Front is arranged at intervals pin hole 5, and 1 side top of chassis setting fixedly connected hole 11,2 side of expansion bracket is arranged at intervals mounting hole 12.
Two stabiliser bars 13 arranged in a crossed manner between corresponding chassis 1, the lower supporting beam 3 of installation on chassis 1 install supporting beam 4 on expansion bracket,
Upper supporting beam 4, lower supporting beam 3 are fixed by pin pin hole, hinged first pulling plate 6 and the second pulling plate 7, lower branch in upper supporting beam 4
It supports and hydraulic jack 8 is set on beam 3, the anticreep pedestal with 8 bottom mating of hydraulic jack is fixedly mounted on lower support top surface of the beam,
Upper support soffit is fixedly mounted and 8 piston rod of hydraulic jack is matched anti-raises one's hat 9.
When promoting operation, chassis 1 to be fixed on steel tower tower body, the first pulling plate 6,7 bottom of the second pulling plate are connect with column foot,
The pin connection between fixed frame 1 and expansion bracket 2 is released, hydraulic jack 8 is operated, expansion bracket 2 and upper supporting beam 4 is jacked up, is led to
Cross the first pulling plate 6, the second pulling plate 7 lifts column foot, when hydraulic jack 8 will reach extreme limit of travel, passed through using pin
Fixedly connected hole 11 and mounting hole 12 fix expansion bracket, and 8 piston rod of hydraulic jack is fallen, and lower supporting beam 3 is unloaded simultaneously
It moves to a pin hole position above to retighten, after connection, releases the pin connection between chassis 1 and expansion bracket 2, operate hydraulic pressure
Jack 8 drives upper supporting beam 4 to continue to rise, and so on, until column foot is promoted to predetermined altitude.
