Description

Column crane mast section rotating assembly tire
One, technical field
The utility model relates to the production corollary apparatus of column crane mast section, is a kind of frock jig that tower machine H type standard knot is produced that is particularly suitable for specifically.
Two, background technology
Along with the development of construction market, scale, the tonnage of tower machine continue to increase, and the common standard joint has not satisfied market demand.H type standard knot is popular in users because of it is simple in structure, easy for installation.The splicing of existing H type standard knot is produced and all is to use fixed splicing frock, fixed frock is at an end above the base plane fixing bent plate to be arranged, and the other end has adjustable angle plate, and adjustable angle plate rotates by leading screw and adjusts the position, blocks or unload workpiece.During work, need the parts of welding to hang in frock with crane, the some postwelding hangs out the frock tire again and is placed on the ground welding, and in the welding process, workpiece will constantly overturn on ground.The advantage of this old-fashioned mold is simple in structure, is convenient to make.But the continuous upset during welding easily causes workpiece deformation, influence product quality, and labour intensity is big, and production efficiency is also lower.
Three, summary of the invention
The purpose of this utility model provides a kind of column crane mast section rotating assembly tire, and it is arbitrarily angled that workpiece can be rotated on frock, and operations such as welding can be finished smoothly.The technical solution adopted in the utility model is: column crane mast section rotating assembly tire comprises the left and right rotating disc that base and base two ends are provided with, left-handed rotating disk is connected on the base through bearing block and left bracing frame, the hydraulic jack and the hydraulic gear that have level to advance in the left-handed rotating disk outside; There is the reductor of rotation support and driven by motor in the dextrorotation rotating disk outside, and the dextrorotation rotating disk supports by rotation and right bracing frame is connected on the base.
It is the workpiece rotation that the utility model contrasts the most significant advantage of old-fashioned frock, but stops by the rotation optional position, welding then, and rotation welding more again forms the flush joint welding, has reduced the welding difficulty, has guaranteed welding quality.Old-fashioned assembly tire is fixed, can not rotate, form upright seam of a lot of welding and dead angle, increased the welding difficulty, thus can only spot welding on frock, hang out the frock welding of overturning on the ground then, because the workpiece tonnage is bigger, it is indeformable to be difficult to assurance in switching process, so, under cover be difficult to the hidden danger of quality of predicting.The utility model adopts hydraulic drive to spur left-handed rotating disk and moves forward and backward, and makes assorted workpiece turnover frock, the lead screw transmission that old-fashioned relatively frock is used, and labour intensity is low, and translational speed is fast, has improved production efficiency.
Four, description of drawings
Fig. 1 is the structural representation of the existing fixed frock of H type standard knot;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the fluid power system schematic diagram of the left-handed rotating disk of the utility model;
Fig. 4 is the structural representation of the utility model dextrorotation dial rotation, support;
Fig. 5 is the structural representation of the left and right rotating disc of the utility model outside rig.
Five, the specific embodiment
Fixed frock jig is that an end has mounting angle plate 4 on base 3, and the other end has adjustable angle plate 2, and there is leading screw 1 adjustable angle plate 2 outsides, shakes leading screw 1 adjustable angle plate 2 is moved horizontally on base 3, workpiece is blocked or unclamps.The effect that the bent plate at fixed frock two ends can only play chucking or loosen workpiece, and the workpiece that can not overturn more can not be holed and be waited other process operations.The utility model is that two ends are provided with left-handed rotating disk 8 and dextrorotation rotating disk 10 on base 3, the outer side center optical axis of left-handed rotating disk 8 is through in the axis hole of bearing block 7, bearing block 7 endwisely slips relatively, and bearing block 7 is fixedlyed connected with left bracing frame 6, and left bracing frame 6 is fixed on the left end of base 3; Be connected with hydraulic jack 5 in the left-handed rotating disk outside, hydraulic jack 5 can drive left-hand rotation dish 8 by connecting rod and move forward and backward, and is installed and dismantles workpiece.The outside of dextrorotation rotating disk 10 has the reductor 12 of driven by motor and revolution to support 11, the outside of dextrorotation rotating disk 10 is connected with the rotating part of rotation support 11, rotation is supported 11 standing part through the right bracing frame 13 of casing 23 connections, and right bracing frame 13 is fixed on the support 3.After the workpiece 9 of needs splicing is installed, electrical power rotation is supported 11 through reductor 12 transmissions revolution and is rotated, and rotates with 0.8r/min speed thereby drive dextrorotation rotating disk 10, workpiece 9, left-handed rotating disk 8, but the optional position stops, and also can stop locking at assigned position.
The utility model has a cover hydraulic gear, operating pressure 40MPa, minimum setting pressure of relief valve 44MPa, oil pump flow 26L/min, maximum thrust 100T, fltting speed 0.8m/min.Hydraulic electric motor 19 energising back driven gear pump 21 rotations, oil enters hydraulic jack 5 by fuel tank 17, screen pack 18, hand-operated direction valve 20, and hydraulic jack 5 is connected on the left-handed rotating disk 8 by connecting rod, drags left-handed rotating disk 8 and moves forward and backward.Limit pressure when oil pressure surpasses, overflow valve 22 is opened, the draining oil sump tank.Left-handed rotating disk 8 tonnages that dragged back and forth are heavier, because configuration rationally, thrust is big, so can realize its function very like a cork.
In order to enhance productivity, two bench drill hole equipment 14 have been set up in the left and right bracing frame outside.Rig 14 is made up of unit head and slide unit 15, when bore motor 24 rotations, drive drill bit 28 rotations by reduction box 25,26 rotations of the motor of feeding simultaneously make slide unit 15 do fast feed and worker's feeding, positioning sleeve 27 is arranged on left and right rotating disc, drill bit 28 inserts under work speed in the positioning sleeve 27, the disposable location drilling work of finishing workpiece.The automatic spacing device is installed on slide unit 15, finish processing tasks after, stopping means action, slide unit 15 is being with drill bit 28 to return fast.
When starting working, left-handed rotating disk is to be in releasing orientation, the assorted H type standard knot monolithic of desire is delivered in the middle of the left and right rotating disc with crane, bent plate 16 with left and right rotating disc inboard is held workpiece, primer fluid pressing system then, hydraulic jack is pushed ahead, and workpiece is sent to assigned address, insert alignment pin (hydraulic drive simultaneously and spinning movement outage are in safe work state) afterwards.In assorted as desire rotational workpieces, can extract alignment pin and start rotary knob and turn to assigned address and work on again and finish (comprise and bore locating hole) up to whole work, and then the primer fluid pressing system, hand-operated direction valve work, hydraulic jack pulls back left-handed rotating disk, hangs out workpiece.
