Abstract

The utility model discloses a cart operation mechanism for a slantingly pulling two-way gantry crane, which comprises a rail trolley arranged on an arc-shaped rail, a buffer device and a rail-cleaning board device which are arranged on the rail trolley, a balance beam arranged at the top of the rail trolley and a supporting seat which is arranged on the balance beam and used for support a door frame. The rail trolley is connected with the balance beam through three rows of roller type slewing bearings. External gear rings of the three rows of roller type slewing bearings are connected with the balance beam through bolts, and the inner gear rings of the three rows of roller type slewing bearings are connected with a bearing support fixed on the rail trolley through the bolts. The cart operation mechanism for the slantingly pulling two-way gantry crane has the advantages that the slewing bearings are used for connecting the balance beam and the rail trolley, advantages of the slewing bearings of bearing axial load, radial load and upsetting moment are fully used, and cart wheels can adapt to the arc-shaped rail at all time so as to avoid deviation of the cart wheels. The cart operation mechanism can bear vertical force during vertically lift and vertical component sub-force and horizontal sub-force during slanting lift.

Description

Be used for tiltedly drawing the traveling mechanism of the larger traveller of bidirectional gate machine
Technical field
The utility model relates to the dam body gate and tiltedly draws the bidirectional gate machine, especially relates to the traveling mechanism of the larger traveller that is used for tiltedly drawing the bidirectional gate machine.
Background technology
Tiltedly draw two-way gantry gate hoists to be widely used on the building of Hydraulic and Hydro-Power Engineering porous mouth.Be used at present tiltedly drawing two-way gantry gate hoists on the dam crest arc-shaped rail, its structure is mainly by traveling mechanism of the larger traveller, be arranged on door frame on the traveling mechanism of the larger traveller, be arranged on the main carriage on the door frame and the lifting mechanism that is arranged on the main carriage is formed by supporting base.The deficiency of its existence mainly shows as: because gantry gate hoists run on the arc track, the axle center of each wheel of traveling mechanism of the larger traveller set of wheels makes the wheelspan that is positioned on inside and outside two tracks not wait all by the track circular arc center of curvature.Adopt at present usually the different wheels of upstream and downstream sidecar wheel footpath, identical and do not produce slip with the angular speed of wheel on the outside track in guaranteeing, simultaneously for easily manufactured, it is contour that four door frame supporting legs are designed to, and adjusts by the height of the balancing stand on the traveling mechanism of the larger traveller.At present adopt sliding bearing to be connected between the bogie frame of traveling mechanism of the larger traveller and the equalizer bar, to adapt to the trace rotation of wheel on arc track; Sliding bearing structure is simple, and is easy for installation, but phenomenon such as sliding bearing exists that operation is dumb, wheel gnawing rail and noise are bigger.
Summary of the invention
The utility model purpose is to provide a kind of stable, traveling mechanism of the larger traveller that is used for tiltedly drawing the bidirectional gate machine that noise is little.
For achieving the above object, the utility model can be taked following technical proposals:
The traveling mechanism of the larger traveller that is used for tiltedly drawing the bidirectional gate machine described in the utility model, it comprises the track chassis that is arranged on the arc track, be arranged on buffer device and clear rail panel assembly on the described track chassis, and be arranged on the equalizer bar at track chassis top and be arranged on the supporting base that is used to support door frame on the described equalizer bar; Described track chassis is connected with equalizer bar by three row's roller pivoting support bearings; The external toothings of described three row's roller pivoting support bearings are connected with equalizer bar by bolt, and ring gear is connected with bearing spider on being fixed on the track chassis by bolt.
The utility model advantage is that the track chassis is except that adopting methods such as the big trundle of existing wide tread, frequency control, creatively floating bearing is applied to being connected of equalizer bar and track chassis, made full use of that floating bearing can bear axially simultaneously, the advantage of radial load and overturning moment, guaranteed that chassis can rotate with respect to equalizer bar, made wheel can adapt to arc orbit all the time to avoid the deflection of wheel.The vertical stress component when vertical force when having solved traveling mechanism of the larger traveller and can bear vertical lifting, inclined pull hoisting and the difficult problem of horizontal component.Again because of it is a rolling bearing, frictional resistance is little and rotate flexibly, overcome the sliding bearing frictional resistance big, easily gnaw rail phenomenon and the big shortcoming of noise.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the traveling mechanism of the larger traveller that is used for tiltedly drawing the bidirectional gate machine described in the utility model, it comprises the track chassis 1 that is arranged on the arc track, be arranged on buffer device 2 and clear rail panel assembly 3 on the described track chassis 1, and be arranged on the equalizer bar 4 at track chassis 1 top and be arranged on the supporting base 5 that is used to support door frame on the described equalizer bar 4; Described track chassis 1 is connected with equalizer bar 4 by three row's roller pivoting support bearings 6; The external toothings of described three row's roller pivoting support bearings 6 are connected with equalizer bar 4 by bolt, and ring gear is connected with bearing spider 7 on being fixed on track chassis 1 by bolt.
