Description
Technical Field
The invention relates to the field of track machinery, in particular to the field of track driving.
Background
The existing monorail crane compound driving device has two modes, namely: a gear is arranged on a common horizontal driving wheel, a rack is horizontally welded above a rail, and the width of the rack is far greater than that of the rail. When the driving part of the monorail crane runs to the track with the toothed rail, the driving group can be unfolded due to the large width of the rack, the hydraulic system can automatically sense the pressure change at the moment, and the pressure is relieved at the same time, so that the gear and the rack can perform occlusion movement, and a friction driving mode is replaced by a gear and rack occlusion mode. When the gear rack is driven out, the reverse is true. The auxiliary device for the rack has the defects that when the monorail crane drives into the rack, pressure must be relieved, and the locomotive loses the braking force. Therefore, the monorail crane must be in the horizontal section when driving into the rack, and cannot have any gradient, and the driving-out section is also the same; the second method comprises the following steps: the gear driving device has the defects that the gear is easy to be not engaged in place when the gear turns, and in addition, the gear driving device and a common device are relatively independent, so that the equipment investment is increased.
Three specific monorail crane compound driving devices are exemplified to illustrate the shortcomings of the existing monorail crane compound driving devices.
The first one is that single track hangs cogged rail drive arrangement includes motor support and cogged rail gallows, and the first end and the cogged rail gallows of motor support are rotationally connected, and the second end still is equipped with on the cogged rail gallows and keeps away the barrier mechanism, keeps away and is equipped with the elasticity portion in the barrier mechanism, and drive gear and cogged rail mesh under the support of elasticity portion. When the rack or the drive gear enters an obstacle, the drive gear cannot be meshed with the rack, and the drive gear is subjected to a force away from the rack. A hydraulic oil cylinder is arranged between the motor bracket and the rack hanger, and the engagement and the disengagement of the gear and the rack are controlled by the extension and the retraction of the hydraulic oil cylinder. The hydraulic oil cylinder is adopted in the device, and the application of the hydraulic oil cylinder makes the structure of the device become complex and the failure is easy to occur.
The second type is a gear monorail crane driving device, the driving device is based on an I-shaped steel track, a row of racks are arranged on the upper end of the I-shaped steel track locally, the two rows of racks are respectively meshed with two driving gears, and the two driving gears are respectively fixed on two friction driving wheels. The two motors are clamped by the clamping device, so that the two motors drive the driving gear to be meshed with the racks on the I-shaped steel. However, the engagement of the gears is only ensured by the pressure relief of the clamping device, which however leads to a brake failure and therefore to complete the engagement in the horizontal section. In addition, because the rack is welded on the I-steel and the whole track needs to be replaced if the local damage occurs, the use cost is invisibly increased.
The third is a single track hangs the engagement device that the rack and pinion inserts or breaks away from, and the device includes hanging wheel, gallows, slewing bracket, gear and pneumatic cylinder. The gear is meshed with or separated from the rack arranged at the bottom side of the track through the extension and contraction of a piston rod of the hydraulic oil cylinder. The device also applies a hydraulic oil cylinder to realize the engagement and disengagement of the gear engagement, and the device is operated manually, and the service life of the gear is shortened due to rigid impact at the moment of engagement.
In addition, the existing monorail crane rails are usually made of I-shaped steel, racks are welded on two sides of the steel rail when climbing road sections or friction force is insufficient, and driving is increased through gear and rack meshing driving.
Therefore, in view of the above problems, there is a need for a friction and gear engagement compound driving device for a monorail vehicle, which has a simple structure and is convenient to operate, so as to improve the working efficiency of the monorail vehicle and reduce the use cost of an application unit.
