The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.The utility model crawler crane from handler comprise two big parts from handler, the one, left and right sides track unit from handler, the 2nd, this machine counterweight from handler.
One, left and right sides track unit from handler
The major part of this device has the pulley gear 2 on the basic arm 1, the transom of the suspension bracket 404 on the track frame and track unit 4 and base 7.
Described left and right sides track unit be on basic arm 1, to set up pulley gear 2 from handler, 25 tons of suspension hooks 3 of adapted.Set up and base bonded assembly guide groove 402 in track frame 401 inboards of track unit 4, the suspension bracket 404 for basic arm suspension hook 3 liftings is respectively set up in the outside in track frame 401 middle parts; Said suspension bracket 404 is that four otic placode 4041 and two minor axises 4042 that are welded on the track frame 401 are fixed on the track frame, two yoke plates 4043 are installed to rotate around two minor axises 4042, two yoke plates, 4043 lower ends connect a major axis 4045, and four spacing sleeves 4044 are arranged on the major axis 4045.Set up the axis of guide 503 that the guiding 402 for track frame snaps at the base beam-ends of base device 5, also be equipped with, and operate the power pin device 501 that penetrates or withdraw from the connecting bore connecting pin for the connecting bore 502 that overlaps with track frame connecting bore 403.
Basis arm 1 top sheave device 2 is to increase pulley gear on existing crane foundation arm in the past, the guiding of steel rope when being used for adorning suspension hook on basic arm when loading and unloading track unit.The track frame suspension centre is it to be made medial and lateral have suspension bracket 404 and the inboard has and base bonded assembly guide groove 402.The type of attachment of track frame 401 and base 5 is taked to have on the base 5 and the track frame bonded assembly connecting bore 502 and the axis of guide 503, and bearing pin connects to be finished by power pin device 501.Seeing also Fig. 1, is the junction of revolution, lifting, luffing action that 25 tons of suspension hooks 3 on the basic arm 1 of track unit 4 usefulness unloaded and did main frame from trailer being adjusted to its installation position gradually base.Lifting is hung in suspension hook 3 on the major axis 4045 of suspension bracket 404 during track unit, and suspension hook 3 is placed on the centre of four spacing sleeves 4044, also can adjust positions with spacing sleeve 4044 and guarantee the track unit balance that lifts.Slinging makes guide groove 402 snap in the axis of guide 503 behind the track unit, and its back, location connecting bore 403 is overlapped with connecting bore 502, and steering maneuver pin assembly 501 makes connecting pin penetrate the installation that connecting bore is finished track unit.During dismounting at first the steering maneuver device withdraw from connecting pin, and then hang.
Said hoisting crane body 6 counterweight self-handlings comprise counterweight and lifting body, and counterweight is to fix seven little clump weights on the big palette 8, and big palette 8 middle parts have the otic placode 801 that is connected additional weight hoisting rope 902 with lifting body 9.Also be equipped with on the otic placode 801 and turntable bonded assembly triangular form connecting bore 803, and the connecting bore 802 that is connected with steel rope.Said lifting body 9 is installed on the turntable 901, is equipped with A type frame transverse axis 903 and pulley gear 904.On A type frame, also be equipped with pivot shaft 905, the lifting rope 902 that is connected for big palette connecting bore 802 is installed on pivot shaft 905.On turntable 901, also be equipped with for the connecting bore bearing pin 907 that penetrates triangular form connecting bore 803 on the big palette.Jacking cylinder 906 1 ends are installed on the turntable 901, and the other end connects to pivot shaft 905.
When A type frame during at low level, additional weight hoisting rope 902 is connected with the connecting bore 802 usefulness bearing pins of big palette, and counterweight jacking cylinder 906 holds up pivot shafts 905.When handling counterweight jacking cylinder 906 and rising, additional weight hoisting rope 902 is big palette 8 pull-ups, when on the triangle connecting bore 803 on the big palette and the turntable 901 be connected the bearing pin coincidence of bearing pin 907 time insert this pin, finish the installation of counterweight.During dismounting, handle counterweight jacking cylinder 906 and transfer to connection bearing pin 907, big palette 8 is descended, promptly detachable counterweight.
