Description
Technical Field
The utility model relates to construction equipment of an ultrahigh bridge pier, in particular to a frame system of a self-climbing type heavy elevator.
Background
the main pier of the Jinyang river in Jinyang county of Xichang city, Sichuan province, has a maximum pier height of 196m which is the first pier in the world of the same type. The pier column is formed into a single-box single-chamber cross section by four-limb lattice columns and concrete rib plates among the columns, each lattice column is composed of a steel pipe with a diameter and concrete with the thickness of 20cm coated outside, and the wall thickness of the concrete rib plates among the lattice columns is 50 cm. C80 self-compacting compensation shrinkage concrete is arranged in the steel pipe, and the other parts are C30 self-compacting compensation shrinkage concrete. Vertical every 12m sets up the cross slab that a 1m is thick in the mound, and the length that divides the segmentation of lattice mound steel pipe is corresponding with the baffle interval. And a flat supporting beam and an inclined supporting beam are arranged between the steel pipes, only the flat supporting beam is arranged along the bridge direction, and the steel pipes are connected with the flat supporting beam by bolts and welded with the inclined supporting beam.
Construction difficulty: firstly, the single steel pipe of the lattice column of the main bridge has large hoisting weight and high hoisting height; secondly, the single steel pipe is long in overhead positioning and splicing operation time and high in safety risk; thirdly, the difficulty of pumping concrete in ultrahigh and long distance is great.
According to the design height and the construction difficulty of the bridge, the actual conditions of all hoisting and lifting equipment in the market at present are combined, and only one set of heavy-duty hoisting machine is specially developed to meet the requirement of bridge construction.
Disclosure of Invention
The utility model discloses the aim at of invention: providing a frame system of a self-climbing heavy-duty elevator; the climbing system and the lifting system of the self-climbing heavy-duty elevator are matched, a frame system with the specification matched with the size of the climbing system and the size of the lifting system is designed, the requirements of installing the climbing system and the lifting system of the self-climbing heavy-duty elevator are met, and the purpose that the self-climbing heavy-duty elevator can normally climb is achieved.
The purpose of the utility model is realized by implementing the following technical scheme:
The utility model provides a from frame system of heavy lifting machine of formula of climbing, includes steel pipe stand, flat brace arm, bracing strut, its characterized in that to one side: four steel pipe upright posts are welded into a frame system of a single hoister through flat supporting arms and inclined supporting arms, and the height of the frame system is 3-4 times of the height of each section of the assembled steel pipe concrete ultrahigh lattice pier; the steel tube concrete ultrahigh-lattice pier is characterized in that two heavy lifting crane arm supporting arms are arranged at the top end of a steel tube upright post of the frame body system in the transverse bridge direction, four groups of rotatable supporting legs are respectively arranged at the bottom and the left and right sides of the middle steel tube upright post of the frame body system in the transverse bridge direction, the rotatable supporting legs are vertically arranged and are arranged in a left-right rotating mode, and the height of each rotatable supporting leg is equal to the height of each section of the assembled steel tube concrete ultrahigh-lattice pier from top to bottom; support leg hydraulic support and retraction rods for controlling the support legs to rotate are horizontally arranged between the left group and the right group of the four groups of rotatable support legs respectively;
In the climbing process of the frame system, the bottom and middle of the steel tube stand column transversely bridge eight groups of rotatable supporting legs at the left and right sides, and the eight groups of rotatable supporting legs are contracted to the inner sides of four steel tube stand columns of the frame system through supporting leg hydraulic support contraction rods, so that the frame system can climb upwards conveniently; when the frame system climbs to the proper position, the support legs are hydraulically propped by the shrinkage rods, and the eight groups of rotatable support legs are propped open, so that sixteen supporting stress points are formed between the eight groups of rotatable support legs and an upper flat support beam and a lower flat support beam of the two-section assembled steel pipe concrete ultrahigh lattice pier; ensuring that the frame system is completely stressed on the upper and lower four flat supporting beams of the two-section assembled steel pipe concrete ultrahigh lattice pier.
The utility model discloses the advantage is: providing a frame system of a self-climbing heavy-duty elevator; the climbing system and the lifting system of the self-climbing heavy-duty elevator are matched, a frame system with the same specification and the same size as the climbing system and the lifting system is designed, the requirements of installing the climbing system and the lifting system of the self-climbing heavy-duty elevator are met, and the self-climbing heavy-duty elevator can normally climb.
