Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As depicted in figs. 1 and 2, the invention provides monorail crane heavy type walking dolly, including two pieces of main frame plate be arrangeding in parallel 1, the fixing reinforcement 2 connected vertically in the middle of every piece of main frame plate 1, two pieces of main frame plate 1 are linked together by the gripper shoe 6 being positioned at bottom reinforcement 2.Wherein, main frame plate 1 is provided with in reinforcement 2 both sides wheel guider 3 and is positioned at the axle bed 14 below wheel guider, axle bed 14 is for installing the directive wheel 15 axially along vertical direction, and the wheel body of directive wheel 15 is arranged in the guiding wheel bore 16 above axle bed 14；Each wheel guider 3 includes seesaw 31, be arranged in seesaw 31 spherical set 32, rotating shaft 33 through spherical set 32, and vertically (Z-direction) through the vertical pivot 34 of seesaw 31, spherical set 32 and rotating shaft 33；Seesaw 31 is each provided with in vertical pivot 34 both sides a through hole 313 for installing carrying wheel 35, for the sake of clarity, Fig. 1 is not drawn into carrying wheel 35, only figure 2 illustrates.The outer surface of spherical set 32 is spherical.Owing to the outer surface of spherical set 32 is spherical, the contact site of spherical set 32 and seesaw 32 is equivalent to one and is hinged, spherical set 32 can rotate freely and smoothly along the horizontal plane in seesaw, that is, seesaw 31 can with the axial direction of rotating shaft 33 for axle, around spherical set 32 left-right rotation, therefore when running into bend, the carrying wheel 15 of the monorail crane walking dolly of the present embodiment freely can be turned along with seesaw 31, rotate together with load without driving trolley, thus reducing frictional resistance when bend runs, it is possible not only to energy-conserving and environment-protective, also solve the load wear problem of monorail crane dolly.Additionally, reinforcement 2 can also strengthen the structural stability of the car frame of the present embodiment.
As shown in Figure 3 and Figure 4, structural representation for wheel guider 3, seesaw 31 is provided with the first through hole 311 along the horizontal direction (X-direction) being perpendicular to main frame plate 1 plate face, spherical set 32 is provided with the second through hole 321 along the first through hole 311 direction, spherical set 32 is arranged in the first through hole 311, and rotating shaft 33 is by the second through hole 321 spherical set 32 of traverse.Seesaw 31 is provided with vertically through the first vertical pivot hole 312 of the first through hole 311, spherical set 32 is provided with vertically through the second vertical pivot hole 322 of the second through hole 321, in rotating shaft 33, correspondence position is provided with the 3rd vertical pivot hole 332, vertical pivot 34 is by the first vertical pivot hole 332, the 312, second vertical pivot hole the 322, the 3rd, the vertical pivot hole traverse spherical set of seesaw 31 32 and described rotating shaft 33, thus seesaw 31, spherical set 32 and rotating shaft 33 being linked together.
Additionally, the edge of main frame plate 1 is further fixedly arranged on bending plate 7, the internal structure of the car frame of the present invention can be played a protective role by bending plate 7.
In addition, as shown in Figure 3 and Figure 4, first vertical pivot hole 312 is the slotted hole along the horizontal direction (Y-direction) being parallel to main frame plate plate face, therefore, seesaw 31 can with vertical pivot 34 for axle, rotate upwardly and downwardly in perpendicular around spherical set 32, therefore when running into ramp, the wheel of the monorail crane walking dolly of the present embodiment freely can rise or fall along with seesaw 31, rotate together with load without driving vehicle frame, thus reducing frictional resistance when slope is run, making monorail crane transport energy-conserving and environment-protective more, also solving the load wear problem of monorail crane dolly.
Additionally, be provided with installing hole with rotating shaft 33 correspondence position in main frame plate 1, installing hole being provided with axle sleeve 11, one end of rotating shaft 33 is provided with axle cap 331, and the other end is through axle sleeve 11 and passes through nut 12 and is fixed in main frame plate 1 with pin 13, as shown in Figure 2.
Wherein, being additionally provided with support ear 8 bottom main frame plate 1, support ear 8 both sides are provided with reinforcement plate, for strengthening the stability of body frame structure for automotive, support ear 8 arrange pin shaft hole 9, and pin shaft hole 9 connects the bearing pin of load-carrying car body for installing.
Wherein, wheel guider 3 is arranged below the otic placode 5 that be connected fixing with main frame plate 1, prop up otic placode 5 to can be not only used for described wheel guider is supported, it is also possible to play the effect of auxiliary stopper, so that the car frame of the present embodiment runs more stable.
In addition, position corresponding with vertical pivot 34 on bending plate 7 is provided with the 4th vertical pivot hole, strengthen journal stirrup 4 is provided with the 5th vertical pivot hole with vertical pivot 34 correspondence position, vertical pivot is along by the 4th vertical pivot hole and the 5th vertical pivot hole, also vertical direction traverse bending plate 7, with strengthen journal stirrup 4, thus wheel guider 3 is fixed in main frame plate 1.
Furthermore, it is possible to grease up on contact surface between seesaw 31 and spherical set 32, so that seesaw is with the more smoothly rotation of motor car wheel.
As shown in Figure 5, for the schematic diagram that the monorail crane heavy type walking dolly of the present invention is installed in orbit, when dolly orbits, lay respectively at 4 directive wheels 15 of track both sides to be close to the side 101 of I shape track lower plate and roll, lay respectively at 8 BOGEY WHEELs 35 of track both sides and be close to the upper surface 102 of I shape track lower plate and roll.
As shown in Figure 6, schematic diagram is turned to for bearing wheed 35 when ramp track (upward slope) runs of the monorail crane heavy type walking dolly of the present invention, for simplicity, not shown directive wheel 15, in figure, black camber line represents track lower plate upper surface, during descending the 35 of bearing wheed turn to similar；As shown in Figure 7, after installing wheel for the monorail crane heavy type walking dolly of the present invention, wheel steering schematic diagram when bend track runs, in figure, black camber line represents the degree of crook of track, can be seen that from Fig. 6 and Fig. 7, the monorail crane car frame of the present invention had both been adapted to bend and had run, and is adapted to again ramp and runs.
The invention provides monorail crane heavy type walking dolly, by being provided with simple and reasonable wheel guider, it is possible not only to the quantity increasing carrying wheel to 8, so that the bearing capacity of walking dolly strengthens, the wheel that can also drive monorail crane dolly swings, adapt to the track with camber, and drive the wheel of monorail crane dolly to swing up and down, adapt to the bend of monorail crane rail, and, in the process of shimmy, whole vehicle frame and loads need not be at once driven to swing, such that it is able to make the friction of monorail crane moving of car reduce, run smooth and easy, it is possible not only to energy-conserving and environment-protective, also solve the load wear problem of monorail crane dolly.
Above in conjunction with accompanying drawing, embodiments of the invention are explained in detail, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, it is also possible under the premise without departing from present inventive concept, make various change.
