Abstract
The utility model discloses an upper chord adjustment type positioning supporting device for a cargo boom of a tower crane. The upper chord adjustment type positioning supporting device is characterized by comprising a fixed seat and a movable supporting adjustment seat, wherein the fixed seat is in a hollow barrel body structure; positioning holes are formed in a barrel body of the fixed seat in a crossed up-and-down intersection manner; the movable supporting adjustment seat is in a hollow barrel body structure; a piece which is shaped like a Chinese character ao is welded on the top of the movable supporting adjustment seat; positioning holes matched with the fixed seat are formed in a barrel body of the movable supporting adjustment seat, and the barrel body of the movable supporting adjustment seat is inserted into the barrel body of the fixed seat; the corresponding positioning holes in the fixed seat and the movable supporting adjustment seat are connected through external positioning pin shafts in a penetrating insertion manner; the movable supporting adjustment seat moves up and down in the fixed seat in a reciprocating manner; high-strength bolts are horizontally symmetrically mounted on two side lugs of the piece which is shaped like the Chinese character ao; an adjustment cushion plate is fixedly mounted on the inner surface of the piece through a screw. The upper chord adjustment type positioning supporting device is suitable for upper chords with different models and different heights and is convenient to repair; the debugging time is shortened, and the working space is saved.
Description
Technical field
The utility model relates to tower crane apparatus field, relates to concretely a kind of derrick runway girder top boom adjustable type device for positioning and supporting.
Background technology
At present, along with tower crane is applied widely, there is the jib for tower crane of differing heights for adapting to Market Design, due to the height difference of crane arm, bring difficulty to fixture location crane arm top boom, in same crane arm, there is two or the crane arm joint of the plural different cross section differing greatly of differing heights, crane arm top boom supporting and location was nonadjustable in the past, two cross sections, in single limb frock, frequently change often support, increase workman's labour intensity, at the bottom of production efficiency, often adjust several millimeters all will change support, the energy of losing time, reduce owing to frequently changing supporting tool precision, having a strong impact on Product Precision and welding quality, in working space, too many owing to supporting, work-yard is limited, working space reduces.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of derrick runway girder top boom adjustable type device for positioning and supporting is provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of derrick runway girder top boom adjustable type device for positioning and supporting, it is characterized in that, this device comprises permanent seat and supports adjusting sliding seat, described permanent seat is hollow cylinder structure, cylindrical shell equal intervals " ten " word top-bottom cross at permanent seat is provided with knock hole, it is hollow cylinder structure that described support regulates sliding seat, welded top has " recessed " type part, on the cylindrical shell of described support adjusting sliding seat, be provided with the knock hole matching with described permanent seat, and be inserted in the cylindrical shell of permanent seat, and regulate the corresponding knock hole of sliding seat by the interspersed connection fixing base of outer detent pin axle and support, support and regulate sliding seat to move back and forth up and down in permanent seat, two of described " recessed " type part is picked up the ears top rail to being symmetrically installed with high strength bolt, on its inner face, be mounted by means of screws with adjusting backing plate, on described adjusting backing plate, be provided with and described screw tapped bore of the same size and thread cap hole.
The beneficial effects of the utility model are, 1), permanent seat of the present utility model and support and regulate cylindrical shell equal intervals " ten " the word top-bottom cross of sliding seat to be provided with knock hole, compare the diplopore accurate positioning in same plane.
2), two of described " recessed " type part pick up the ears top rail to being symmetrically installed with high strength bolt, the maintenance rate of employing high strength bolt minimizing workpiece.
The utility model is by crane arm top boom supporting and location assembly and the welding of different model and height dimension, ensure the dimensional accuracy between crane arm top boom and relevant connection parts, reduced the time that debugging is prepared simultaneously, be convenient to maintenance, improve greatly production efficiency, also save working space owing to having reduced the quantity of supporting seat, having realized.
