Description
Technical field
The present invention relates to a kind of machine-walking device, particularly relate to a kind of self-adapting following walking method and structure of machine-walking device.
Background technology
At the harbour or the goods yard often use gantry type or bridge weight-lifting equipment, door frame or crane span structure are generally steel structure frame, below door frame or crane span structure traveling gear are set, traveling gear is walked in orbit.Externally under the effect of load, door frame or crane span structure can produce distortion, thereby can influence the normal operation of traveling gear.In addition, because the distortion that the installation error of track or basic displacement produce also can influence the normal operation of traveling gear, gnaw rail and the big phenomenon of running noises through regular meeting, traveling gear can't move when serious.
Summary of the invention
The objective of the invention is to, a kind of self-adapting type following walking device is provided, to solve because door frame or the distortion of crane span structure steel structure, or the installation error of track, the or influence problem that traveling gear normally moves during basic displacement.The present invention can be good at adapting to the influence that track deformation brings, and wheel orbits steadily, and noise is little, can not gnaw the rail phenomenon.
Technical scheme of the present invention: self-adapting following walking method, by between the vehicle wheel frame of running gear and door frame, setting gradually the balance that oscillating bearing and linear bearing come the automatically regulating running gear.
In the above-mentioned self-adapting following walking method, described linear bearing is the linear bearing that can move along the vertical direction of track at horizontal surface.
In the aforesaid self-adapting following walking method, described oscillating bearing is to be the fulcrum running gear with the bearing along the two-freedom bearing of orbit plane left rotation and right rotation and rotation before and after the vertical surface of orbit plane.
Realize the device of aforementioned self-adapting following walking method, comprise the wheel that rolls in orbit, wheel is fixed on the vehicle wheel frame, and vehicle wheel frame is connected with door frame; Between vehicle wheel frame and door frame, be provided with oscillating bearing and linear bearing successively.
In the above-mentioned self-adapting type following walking device, the moving direction of described linear bearing is vertical with track alignment at horizontal surface.
In the aforesaid self-adapting type following walking device, described oscillating bearing is the two-freedom bearing.
In the aforesaid self-adapting type following walking device, described vehicle wheel frame both sides are provided with track adjusting wheel.
Compared with prior art, the present invention can realize dynamically moving, no matter be under the effect of externally load, the distortion that door frame or crane span structure steel structure produce, still because the distortion that the installation error of track or basic displacement produce, running gear can both well adapt to, and guarantees the normal operation of traveling gear, can not gnaw phenomenons such as rail and running noises are big.The present invention can be widely used in the various mechanical running mechanisms, and the mechanical running mechanism than the macrostructure distortion is especially arranged.

The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Embodiment.Self-adapting type following walking method of the present invention and device, be mainly used in the gantry type or the bridge weight-lifting equipment in harbour or goods yard, door frame or crane span structure 1 are generally steel structure frame as shown in Figure 4, as can be seen from Figure 4, below door frame or crane span structure 1 traveling gear is set, traveling gear is walked on track 4.Externally under the effect of load, door frame or crane span structure 1 can produce distortion as shown in Figure 5, and as can be seen from Figure 5, door frame or crane span structure 1 following wheel 3 have tilted, and have outwards moved a segment distance, therefore can influence the normal operation of traveling gear.In addition, because the distortion that the installation error of track or basic displacement produce also can influence the normal operation of traveling gear, gnaw rail and the big phenomenon of running noises through regular meeting, traveling gear can't move when serious.
Principle of work of the present invention as shown in Figure 1, it is by set gradually the balance that oscillating bearing and linear bearing come the automatically regulating running gear between the vehicle wheel frame of running gear and door frame.Oscillating bearing is the fulcrum running gear with the bearing along about the orbit plane and two degree of freedom rotations before and after the vertical surface of orbit plane.Linear bearing can move the vertical side of horizontal surface along track.Described track can be a straight rail, also can be the track of turning, and when being used for straight rail, linear bearing can move the vertical side of horizontal surface along track.During the track that is used to turn, when track was the bend of arc, linear bearing can be done straight line along the arc radius direction of track at horizontal surface and move.
Concrete structure as shown in Figures 2 and 3, it comprises the wheel 3 that can roll on track 4, wheel 3 is fixed on the vehicle wheel frame 2, vehicle wheel frame 2 is connected with door frame or crane span structure 1; Improvement of the present invention is: be provided with oscillating bearing 6 and linear bearing 5 successively between vehicle wheel frame 2 and door frame or crane span structure 1.Linear bearing 5 can the direction along ng a path sway, and so-called sway is meant in the vertical direction of horizontal surface along track and moves, or moves in the arc radius direction of horizontal surface along track.Linear bearing 5 adopts the garden post roller structure of high-mechanic load, utilizes coro bearng to have the low characteristic of friction drag, also makes linear bearing 5 can bear combined stresses such as vertical load, horizontal load and capsizing moment.Oscillating bearing 6 is the two-freedom bearing.It is that fulcrum rotates along about orbit plane by a small margin with the bearing, to overcome the influence that wheel 3 tilted and displacement causes when door frame or crane span structure 1 were out of shape; Can bearing be that fulcrum rotates before and after the vertical surface of orbit plane by a small margin also, operation impacts to traveling gear to overcome front and back wheel 3 vertical deviations.But cannot in the plane of the moving direction of linear bearing 5, rotate, avoid influencing the normal of linear bearing 5 and move.In order to guide moving of linear bearing 5, and better guide the traveling gear operation, horizontal guide sheave 7 is installed in vehicle wheel frame 2 both sides.
