Abstract
The utility model relates to a lifting mechanism of a gantry crane, in particular to a lifting mechanism of a gantry crane, which is applied to a base of a decelerator and supported elastically. The lifting mechanism of the gantry crane disclosed by the utility model is characterized in that the input shaft of the decelerator is connected with a motor through a coupler; the low-speed output shaft end of the decelerator is connected to a small gear; the small gear is meshed with a large gear at the end of a roller; three elastic supports are distributed at the bottom of the decelerator like a Chinese character pin; the elastic support is composed of an elastic component, an adjustable screw, a locking nut and a stud base; the adjustable screw is screwed in the stud base; the locking nut is sleeved on the adjustable screw; and the elastic component is arranged on the top of the adjustable screw. Because the three elastic supports are additionally arranged at the flexible end at the bottom of the decelerator, the vibration caused by flexible support is absorbed; most of vertical offset distance caused by vibration is overcome; the vibration condition under the working state is greatly improved; and the limit caused by the practical condition is overcome.
Description
Technical field
The utility model relates to a kind of gauntry crane lifting mechanism, particularly relates to a kind of retarder slow-speed shaft and goes out the gauntry crane lifting mechanism that axle head does not have coupler, and specifically a kind of retarder base is with the gauntry crane lifting mechanism of resilient mounting.
Background technology
Large gantry crane is provided with upper and lower dolly, and last dolly has two lifting mechanisms, and following dolly has a lifting mechanism (seeing Fig. 1 master layout).With shipbuilding base, Changxing, south of the River 600T gauntry crane is example, and last dolly is 2 300T lifting mechanisms, and in order to lifting 600T member, suspension hook both wings outside girder are arranged.Following dolly has the 450T lifting mechanism, and suspension hook arranges that with the girder line of centers following dolly can pass, and stands up in order to lift member with three hooks simultaneously under last dolly.No matter be the twin-spar construction or the gauntry crane of single-spar construction; Girder overall width and upper and lower dolly overall width have a proper proportion; Last dolly both sides sponson is not more than the girder overall width, and dolly will pass below last dolly down, has more restricted the overall width of time dolly machine room.
Fig. 2 is the dolly lifting mechanism birds-eye view of prior art; During last dolly machine room is arranged: go up dolly two cover lifting mechanism symmetric arrangement; And suspension hook also has 2 meters extension distance; So the machine room position is limited to, retarder 4 slow-speed shafts go out axle head should have a cover coupler, to absorb slow-speed shaft and miniature gears 7 owing to the offset distance vibration that decentraction was caused is installed.But because the restriction of machine room width cuts this cover coupler.See Fig. 3, portion lets slow-speed shaft float with torque arm 5 supports in the high speed shaft bottom to have adopted retarder 4 bottoms, with absorbing polarization.In actual the use,, make miniature gears 7 vibrations, quickened the gear pair wearing and tearing, simultaneously, when lifting velocity reaches 50% command speed, produce violent resonance, influence door machine normal operation because retarder 4 one ends float.
Summary of the invention
The purpose of the utility model provides a kind of gauntry crane lifting mechanism; Particularly relate to a kind of retarder slow-speed shaft and go out the gauntry crane lifting mechanism that axle head does not have coupler, specifically a kind of retarder base is with the gauntry crane lifting mechanism of resilient mounting.Flex end has increased by three resilient mountings to the utility model in the retarder bottom; These resilient mountings have absorbed because the vibration that flexible strut produces; Overcome most of offset distance up and down that produces by vibration; Improved the vibration state under the mode of operation greatly, overcome when designing because the limitation that produces under the actual state.
A kind of gauntry crane lifting mechanism of the utility model; Input shaft of speed reducer connects with motor through coupler; Between retarder and the coupler drg is installed, the slow-speed shaft of retarder goes out axle head and connects miniature gears, and the center shaft two ends of miniature gears are supported by bearing seat; The big gear wheel engagement of miniature gears and reel termination, described retarder bottom " article " font is distributed with three resilient mountings; Described resilient mounting is made up of elastic element, adjusting screw, jam nut and stud seat, and adjusting screw is screwed in the stud seat, and jam nut is enclosed within on the adjusting screw, and elastic element is equipped with on the top of adjusting screw.
Beneficial effect
A kind of gauntry crane lifting mechanism of the utility model; Flex end has increased by three resilient mountings in the retarder bottom; These resilient mountings have absorbed because the vibration that flexible strut produces; Overcome most of offset distance up and down that produces by vibration, improved the vibration state under the mode of operation greatly, overcome the limitation that actual state produces.

Fig. 3 is the dolly lifting mechanism front elevation of prior art
Fig. 4 is the resilient mounting scheme drawing
Fig. 5 is a kind of gauntry crane lifting mechanism upward view of the utility model
Wherein, the 1st, motor 2 is that coupler 3 is that drg 4 is that retarder 5 is that torque arm 6 is that bearing seat 7 is that miniature gears 8 is that big gear wheel 9 is that reel 10 is that elastic element 11 is that adjusting screw 12 is that jam nut 13 is stud seats
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model.
Shown in accompanying drawing 5; Be a kind of gauntry crane lifting mechanism of the utility model, the input shaft of retarder 4 connects with motor 1 through coupler 2, between retarder 4 and the coupler 2 drg 3 is installed; The slow-speed shaft of retarder 4 goes out axle head and connects miniature gears 7; The center shaft two ends of miniature gears 7 are supported by bearing seat 6, and miniature gears 7 meshes with the big gear wheel 8 of reel 9 terminations, and described retarder 4 bottoms " article " font is distributed with three resilient mountings; Described resilient mounting (see figure 4) is made up of elastic element 10, adjusting screw 11, jam nut 12 and stud seat 13; Adjusting screw 11 is screwed in the stud seat 13, and jam nut 12 is enclosed within on the adjusting screw 11, and elastic element 10 is equipped with on the top of adjusting screw 11.
Through evidence; The flex end in the retarder bottom of the utility model has increased by three resilient mountings, has absorbed because the vibration that flexible strut produces has overcome most of offset distance up and down that is produced by vibration; Improve the vibration state under the mode of operation greatly, overcome the limitation that actual state produces.
