In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

a supporting trolley device of a bridge type reversed loader capable of preventing a lane from being laterally inclined comprises two groups of frames, wherein supporting frames are fixedly arranged above the frames, one end of each of two groups of damping devices is fixedly arranged on the upper surface of each supporting frame, the other end of each damping device is fixedly arranged on the lower surface of a cross beam, and the cross beam is hinged to a discharging frame of a belt frame through a pin shaft; the lower surface of the frame is movably connected with a supporting wheel through a bearing, a flange is arranged on the inner side surface of the supporting wheel along the circumferential direction, and the flange is movably clamped on the inner side of the track.

Preferably, a plurality of anti-falling wheels are arranged on the outer side surface of the frame.

Preferably, the support frame includes triangle balancing stand and backup pad, the triangle balancing stand is the form of falling triangle, just the inside at the frame is installed through rolling bearing in the bottom of triangle balancing stand, backup pad fixed mounting is at the upper surface of triangle balancing stand, damping device's lower extreme passes through fixing bolt fixed mounting at the upper surface of backup pad.

The utility model provides a prevent that incline falls bridge type elevating conveyor supporting trolley device of saying. The method has the following beneficial effects: the flange on the inner side of the supporting wheel can prevent the supporting wheel from being separated from the track, and meanwhile, better consistency can be ensured when the supporting wheel is moved forwards and backwards; the two damping devices are arranged on the upper surface of each supporting frame, so that when the bottom plate fluctuates and the heading machine shakes violently, the supporting trolley can keep the belt surface level and is in good contact with the rail, the falling of the belt is avoided, the overturning acting force on the belt frame is effectively reduced, and the hidden trouble in operation is eliminated. The anti-falling wheels are arranged on the outer side of the frame, so that the trolley is fixed on the track when the supporting trolley receives transverse impact or twisting, and the travelling direction of the trolley is ensured not to deviate.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of a middle view screen laryngoscope according to the present invention;

the reference numbers in the figures illustrate:

1. a frame; 2. a support frame; 3. a damping device; 4. a cross beam; 5. a bearing; 6. a support wheel; 7. a flange; 8. a falling-off prevention wheel; 9. a triangular balancing stand; 10. and a support plate.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention will be combined below to clearly and completely describe the technical solutions of the present invention.

As shown in fig. 2, the supporting trolley device of the anti-roll-off bridge type reversed loader comprises two sets of frames 1, wherein supporting frames 2 are fixedly arranged above the frames 1, one end of each of two sets of damping devices 3 is fixedly arranged on the upper surface of each supporting frame 2, the other end of each damping device 3 is fixedly arranged on the lower surface of a cross beam 4, and the cross beam 4 is hinged on a belt frame discharging frame through a pin shaft; the lower surface of the frame 1 is movably connected with a supporting wheel 6 through a bearing 5, a flange 7 is arranged on the inner side surface of the supporting wheel 6 along the circumferential direction, and the flange 7 is movably clamped on the inner side of the track.

When the belt conveyor is in operation, the four supporting wheels 6 straddle the track of the belt conveyor, and the flanges 7 on the inner side surfaces of the supporting wheels 6 are movably connected with the track from the inner side of the track, so that the supporting wheels 6 can be prevented from being separated from the track, and meanwhile, better consistency can be ensured when the belt conveyor is moved forwards and backwards; through all being provided with two damping device 3 at every support frame 2 upper surface to when the bottom plate fluctuates, entry driving machine work vibrations are violent, the support dolly can keep the area level, with the track good contact, has stopped the derail, has effectively reduced the effort of toppling the belt frame, eliminates the operation hidden danger.
