In order to prevent the vehicle from being detached from the control of the dumper from the side of dumping beyond 180 °, the overturning angle of the dumper is normally 165 ° and 175 ° at maximum. In order to adapt to vehicle types with different widths and heights, the pressure head of the dumper is generally longer than the upper edge beam of the open wagon, so that materials still cannot be dumped at the maximum dumping angle due to the length of the pressure head and the like, and a certain stock exists. For many years, in the field of car dumpers, various corresponding schemes are developed, and materials cannot be discharged.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 and 2 are mechanism components of a conventional dumper, and specifically comprise dumper carrier rollers and dumper rotors, wherein a dumper side pressure girder 1 and a dumper opposite side pressure girder 2 are positioned on a dumper rotor 4 and are used for pressing and holding a top boundary girder of an open wagon 8 from top to bottom; the dumping side leaning plate 3 is positioned on the dumping side of the dumper rotor 4 and is used for supporting the side surface of the open wagon from the dumping side; the dumper rotor 4 is positioned on the dumper carrier roller 7 and can rotate on the dumper carrier roller 7; the dumper platform 5 is a part of the dumper rotor 4 and supports an open wagon 8 through wheels 9; the dumping opposite side platform guard rail 6 is connected to the dumper platform 5 and is used for blocking the side surfaces of the wheels 9 of the open wagon 8 at the dumping opposite side in the overturning process, so that the wheels 9 are prevented from being separated from the rails on the dumper platform 5 from the side surfaces due to gravity in the overturning process; the dumper carrier roller 7 is a supporting device of the dumper rotor 4, and the dumper rotor 4 can overturn and discharge materials on the dumper carrier roller.
The working principle of the existing car dumper is shown in the accompanying figures 1 and 3:
after the material 10 transported by the open wagon 8 enters the wagon tipper rotor 4, the material is stopped on the wagon tipper platform 5, the side wagon beam 1 and the opposite side wagon beam 2 are dumped and pressed on the wagon tipper from the upper side, and the fixation in two directions of the vertical direction is realized through the platform 5; after the pressing is finished, the dumping side backup plate 3 moves from the dumping side to the vehicle and leans against the dumping side of the open wagon; after the 3-direction fixing of the vehicle is completed, the dumper rotor 4 rotates to the dumping side and drives all parts and the vehicle to rotate, and when the dumping angle is larger than the repose angle a of the materials 10 in the open wagon, the materials begin to be dumped from the wagon until the dumper rotor 4 is dumped to the maximum dumping angle A.
As shown in fig. 4, during a roll-over process at 90 ° to the maximum roll-over angle a, the wheels 9 of the vehicle 8 have a tendency to slide down and be caught by roll-over counter-platform guard rails on the roll-over platform 5.
In order to prevent the vehicle from falling out of the side of the gap, the maximum roll-over angle a is generally not greater than 180 °.
As shown in fig. 5, there will be a residual material 10 between the tipping side pressure holding beam 1 and the open car 8 due to the presence of the angle of repose a.
It can be seen that: as the flip angle becomes greater, the residual material will correspondingly decrease until the flip angle is greater than 180 + the material repose angle, and no residual material will be present.
Compared with the existing dumper of fig. 1, as shown in fig. 6, the dumper of the invention is added with a dumping opposite side supporting device 11 and a newly added dumping side platform guard rail 12, wherein the newly added dumping opposite side supporting device 11 is positioned on a dumper rotor 4 and positioned on a dumping opposite side of the dumper, is used for leaning against the dumping opposite side surface of the open wagon 8 from the dumping opposite side, and is used for preventing the wagon 8 from falling out from the dumping opposite side after the dumper exceeds 180 degrees; the new side platform guard rail 12 that turns over is used for stopping the wheels 9 of the open wagon 8 on the side that turns over after turning over 180 degrees.
The working principle of the non-accumulation dumper is as shown in the accompanying figures 6-7:
after the material 10 transported by the open wagon 8 enters the wagon tipper rotor 4, the material is stopped on the wagon tipper platform 5, the wagon tipper is pressed by the side wagon beam 1 and the opposite side wagon beam 2 from the upper side, and the fixation in two directions of the vertical direction is realized through the platform 5; after the pressing is finished, the dumping side backup plate 3 moves from the dumping side to the open wagon 8 and abuts against the dumping side of the open wagon 8; meanwhile, the dumping opposite side supporting device 11 moves to the side of the dumping opposite side vehicle, after the fixing of the vehicle in the up-down direction and the left-right direction is completed, the dumper rotor 4 rotates to the dumping side and drives all parts on the dumper rotor, the vehicle 8 and the materials 10 to rotate, when the dumping angle is larger than the repose angle a of the materials 10 in the open wagon 8, the materials 10 begin to be dumped from the open wagon 8, and before the dumper rotor 4 is overturned to 180 degrees, the working process of the dumper rotor is the same as that of the conventional dumper shown in the attached drawings 1 and 3; as shown in fig. 8 and 9, after the turning angle exceeds 180 °, the newly added supporting device 11 supports the vehicle 8 so that the vehicle does not fall out from the opposite turning side, and the newly added turning side platform guard rail 12 blocks the wheels 9 of the open wagon 8 until the turning is stopped after the turning angle 180 ° + turning angle B, the larger the turning angle B is, the less the accumulation is, if the turning angle B is not less than the repose angle a of the material, all the materials between the press beam 1 and the vehicle 8 will be discharged, and the accumulation is avoided.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
