Compared with the prior art, the gantry crane cart traveling device can drive the traveling wheels on two sides of the bearing beam to travel synchronously; the phenomenon of rail gnawing is avoided, and the service life of the gantry crane cart traveling device is prolonged.
Description
Technical field
The present invention relates to gauntry crane manufacturing technology field, especially a kind of running gear for gantry crane.
Background technology
Gauntry crane is mainly used in the loading and unloading operation of outdoor goods yard, stock ground goods, bulk goods.Have a kind of gantry crane running gear, this gantry crane running gear comprises that both sides are provided with the door-shaped frame of carrier bar, and described door-shaped frame is provided with a fortune coal bunker on the described carrier bar of a side; Below each described carrier bar, mobile roof support is all installed, described mobile roof support is equipped with the first row travelling wheel and the second road wheel by the first wheel shaft and the second wheel shaft respectively, the first gear and the second gear are housed respectively on described the first wheel shaft and described the second wheel shaft and are located at intermediate gear between the two, intermediate gear is contained on described mobile roof support by tween drive shaft; Described the first gear and described intermediate gear and described intermediate gear and described the second gear are connected with a joggle, and described the first wheel shaft is connected with the first actuating device by middle parts.In use there are the following problems for this gantry crane running gear: because a side of carrier bar has a coal bunker car, when unloaded 8.3 tons, add 22.7 tons of whens load, therefore when walking, coal bunker has the duty ratio opposite side of running gear of the carrier bar side of load large, causes both sides walking asynchronous, causes and gnaws rail phenomenon, easily cause reductor to damage, shorten the service life of cart traveling device; In addition, owing to being provided with, the load variations of carrier bar side of coal bunker is large, and gap bridge tooth discontinuity is easily damaged, and not only maintenance of equipment expense is high, has also incured loss through delay and has unloaded coal, transports the coal time, has increased productive costs.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of synchronous gantry crane running gear of running gear that can make gauntry crane both sides.
In order to address the above problem, the technical solution adopted in the present invention is: this gantry crane running gear comprises that a side is provided with the carrier bar of a fortune coal bunker, be provided with mobile roof support in described carrier bar bottom, described mobile roof support is equipped with the first row travelling wheel and the second road wheel by the first wheel shaft and the second wheel shaft respectively, described the first wheel shaft is connected with the first actuating device by middle parts, described the second wheel shaft is connected with the second actuating device, described the second actuating device comprises the retarder being connected with described the second wheel shaft by coupler, described retarder is connected with engine by drg.
In above-mentioned gantry crane running gear technical scheme, technical scheme can also be more specifically: described the first wheel shaft is connected with actuating device separately respectively with described the second wheel shaft, the actuating device of described the first wheel shaft is described the first actuating device, and the actuating device of described the second wheel shaft is described the second actuating device.
Further, described engine is electrical motor.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, due to the even actuating device that is connected with of two road wheels on the mobile roof support below the carrier bar being provided with fortune coal bunker, therefore, the traction drive ability that is provided with the carrier bar side of fortune coal bunker increases, the side direction torsion of the asynchronous generation of both sides road wheel when the traction drive ability increasing has been offset the load of fortune coal bunker, impel the road wheel walking of carrier bar both sides synchronous, prevent from the walking generation of rotation browsing rail phenomenon, the service life of having improved gantry crane running gear; 2, because the second wheel shaft increases actuating device, the friction force of road wheel and track is improved, and no longer needs to be connected to the intermediate gear of two wheel between centers, reduces production costs.

Fig. 3 is the cutaway view at the A-A place of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
As shown in Figure 1 be existing gantry crane running gear, this gantry crane running gear comprises the door-shaped frame that is contained in both sides and is equipped with carrier bar 10, a fortune coal bunker is installed on the carrier bar of door-shaped frame one side, mobile roof support is all installed below each carrier bar, mobile roof support is equipped with the first row travelling wheel 1a and the second road wheel 2a by the first wheel shaft 1a-1 and the second wheel shaft 2a-1 respectively, the first gear 1a-2 and the second gear 2a-2 are housed respectively on the first wheel shaft 1a-1 and the second wheel shaft 2a-1 with being contained in the first gear 1a-2 and the second gear 2a-2 intermediate gear 3a between the two, intermediate gear 3a fills 3a-1 by tween drive shaft and is contained on mobile roof support, the first gear 1a-2 and intermediate gear 3a and intermediate gear 3a and the second gear 2a-2 are connected with a joggle, and the first wheel shaft 1a-1 is connected with the first actuating device 4 by middle parts, because a side of carrier bar has a coal bunker car, when unloaded 8.3 tons, add 22.7 tons of whens load, therefore when walking, coal bunker has the duty ratio opposite side of running gear of the carrier bar side of load large, causes both sides walking asynchronous, causes and gnaws rail phenomenon, easily cause reductor to damage, shorten the service life of cart traveling device.
As Fig. 2, shown in Fig. 3 is gantry crane running gear of the present invention, this gantry crane running gear comprises that a side is provided with the carrier bar 10 of a fortune coal bunker, in carrier bar 10 bottoms, mobile roof support 9 is housed, mobile roof support 9 is equipped with the first row travelling wheel 1 and the second road wheel 2 by the first wheel shaft 1-1 and the second wheel shaft 2-1 respectively, the first wheel shaft 1-1 is connected with the first actuating device 4 by middle parts, the first wheel shaft 1-1 is connected with actuating device separately respectively with the second wheel shaft 2-1, the actuating device of the first wheel shaft 1-1 is the first actuating device 4, the device of the second wheel shaft 2-1 is the second actuating device, the second actuating device comprises the retarder 6 being connected with the second wheel shaft 2-1 by coupler 5, and retarder 6 is connected with engine by drg 7, engine 8 is electrical motor, the first wheel shaft 1-1 is connected with actuating device separately respectively with the second wheel shaft 2-1, and the actuating device of the first wheel shaft 1-1 is that the device of the first actuating device 4, the second wheel shaft 2-1 is the second actuating device.Due to the even actuating device that is connected with of two road wheels on the mobile roof support 9 below the carrier bar 10 being provided with fortune coal bunker, therefore, the traction drive ability that is provided with the carrier bar side of fortune coal bunker increases, the side direction torsion of the asynchronous generation of both sides road wheel when the traction drive ability increasing has been offset the load of fortune coal bunker, impel the road wheel walking of carrier bar both sides synchronous, prevent from the walking generation of rotation browsing rail phenomenon, the service life of having improved gantry crane running gear.
