Abstract
The utility model relates to an attaching frame of a tower crane. The attaching frame comprises a U-shaped welding component, a connecting plate, lug plates and a fastening device, wherein each U-shaped welding component is formed by combining and welding a quadrate tubular steel beam and two short quadrate tubular steel beams; two U-shaped welding components are integrally connected through a connecting plate to form a framework of an attaching frame; the fastening device is fixed to the short quadrate tubular steel beam of the U-shaped welding component and close to the welding end; the plugs are fixed to two ends of the bottom of one U-shaped welding component; the parts at which the quadrate tubular steel beam and the short quadrate tubular steel beam are welded are cut at an inclined angle of 45 degrees; and the cutting parts at the inclined angle of 45 degrees and the welding parts are covered by welding fixing plates. The attaching frame can be used for saving the time, the material and the labor, has high strength, and is stable in structure, and convenient to popularize in the market.
Description
Technical field
The utility model relates to a kind of vehicle for construction parts, is specifically related to a kind of tower crane and exceeds the mount structure that adheres to that plays firm effect behind the certain altitude.
Background technology
Tower crane is widely used in the realm of building construction; Along with skyscraper is more and more; Operating altitude to tower crane requires also improving, when the tower machine reach a certain height, for guaranteeing its stability; Must use attachment device to couple together tower machine and building, thereby guarantee the stable safety of construction.Attachment device is generally formed by adhering to frame, attached bar, attachment device attaching parts.
Use the more general mount structure frame that adheres to generally to adopt a U-shaped weldment and a girder steel to be formed by connecting at present with bearing pin; Wherein the U-shaped weldment adopts angle steel, channel-section steel assembly welding to become three girder steel assembly weldings of I font, and traditional structure is at the section vertical cut, is 90 ° of right angle overlap joints then; Also will be in the termination welding steel plate block the mouth of welded tube head; Also to use steel plate reinforcement at last, because solder joint too much can cause structure stretch bending, the distortion of steel, not only intensity out of reach; And time-consuming, expense material, take a lot of work, also when welding, section bar is deformed easily.
The utility model content
The purpose of the utility model be save time in order to solve the problem that prior art exists, to provide a kind of, material-saving, saving of labor, intensity are high, constitutionally stable tower crane adheres to mount structure.
The technical scheme of the utility model: a kind of tower crane adheres to frame, comprises the U-shaped weldment, connecting panel, and otic placode, securing device, each U-shaped weldment is made up of a rectangular pipe girder steel and two short square tube girder steel Combination Welding; Two U type weldments link together to constitute through connecting panel and adhere to the circle frame; Securing device is fixed in the short square tube girder steel of U type weldment near welding end; Otic placode is fixed in two ends, a U-shaped weldment bottom; The rectangular pipe girder steel is 45 ° of oblique angle cuttings with short square tube girder steel weld; Oblique angle cutting, weld adopt the adapter plate welding to cover.
Two otic placodes of the utility model can adopt double layer design, are parallel to each other.
Each U-shaped weldment of the utility model is established a securing device, and two U-shaped weldments are assembled into tower crane when adhering to frame, and securing device is positioned at and adheres to frame the same side.
The securing device 5 of the utility model is made up of movable bolt and baffle plate, and movable bolt is captiveed joint with baffle plate through bolt passage one end on the short square tube girder steel 2, and baffle plate is positioned at and adheres to the frame inboard.
The technique effect of the utility model: through the optimization of selection, substitute traditional angle steel, channel-section steel, improved production efficiency with square hollow section steel; Reduced productive costs, through the optimization of manufacture craft, to 45 ° of cuttings of square hollow section steel, welding; Compare traditional section vertical cut; Be 90 ° of right angle overlap joints, welding then, saved many weldering nodes, reinforcement of weld plate on oblique fillet; A series of improvement have solved solder joint and have too much caused the structure stretch bending of steel, the shortcoming of distortion, have improved and have adhered to frame bulk strength and steadiness.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, but is not limited to embodiment.
A kind of tower crane adheres to frame, comprises the U-shaped weldment, connecting panel 3, and otic placode 4, securing device 5, each U-shaped weldment is made up of a rectangular pipe girder steel 1 and two short square tube girder steel 2 Combination Welding; Two U type weldments link together to constitute through connecting panel 3 and adhere to the circle frame; Securing device 5 is fixed in the short square tube girder steel 2 of U type weldment near welding end; Otic placode 4 is fixed in two ends, a U-shaped weldment bottom; Rectangular pipe girder steel 1 is 45 ° of oblique angle cuttings with short square tube girder steel 2 welds; Oblique angle cutting, weld adopt adapter plate 6 welding to cover; Two otic placodes 4 all adopt double layer design, are parallel to each other; Each U-shaped weldment is established 5, two U-shaped weldments of a securing device and is assembled into tower crane when adhering to frame, and securing device 5 is positioned at and adheres to frame the same side; Securing device 5 is made up of movable bolt and baffle plate, and movable bolt is captiveed joint with baffle plate through bolt passage one end on the short square tube girder steel 2, and baffle plate is positioned at and adheres to the frame inboard.When the utility model uses; Earlier rectangular pipe girder steel and short square tube girder steel welding end are done 45 ° of oblique angle cuttings, assembly welding becomes U type weldment then, then U type weldment is placed tower machine fuselage outer side; Through tightening the movable bolt on the securing device; Make baffle plate push against tower machine fuselage, again another U type weldment is fitted together with it through connecting panel, adjust securing device at last once more and make and adhere to the whole and tower machine fuselage of frame closely, firmly link together.
