Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.
Example 1
A transport vehicle for transporting a railway rolling stock wheel set, comprising a vehicle body 100, said vehicle body 100 being provided with a motor drive system 1, said motor drive system 1 being adapted to drive the vehicle body 100. The driving mechanism of the vehicle body 100 may be a wheel type driving mechanism or a crawler type driving mechanism, and the crawler type driving mechanism is adopted in the embodiment, so that the friction force is large and the maintenance is convenient. The hydraulic auxiliary system 2 is in transmission connection with the motor drive system 1 through the coupling mechanism 4, and the hydraulic auxiliary system 2 is used for auxiliary driving of the vehicle body 100 and recovery of kinetic energy of the vehicle body 100, namely, the hydraulic motor 3 is used as a motor and a hydraulic pump in the embodiment. The vehicle body 100 is provided with a pushing device 20, and the pushing device 20 is used for pushing the wheel set.
In particular, in connection with fig. 9, the hydraulic auxiliary system 2 comprises a hydraulic motor 3, and the output end of the motor driving system 1 is connected with the output end of the hydraulic motor 3 through a coupling mechanism 4, wherein the coupling mechanism 4 can be a rotating speed coupling mechanism or a torque coupling mechanism, and the embodiment is preferably a planetary gear coupling mechanism so as to connect the motor driving system 1 and the hydraulic auxiliary system 2 in a transmission manner with a wheel or a driving shaft of a transport vehicle for transporting a railway locomotive wheel set.
The hydraulic motor 3 is respectively connected with the high-pressure energy accumulator 6 and the low-pressure energy accumulator 7 through the three-position four-way electromagnetic valve 5, and it is understood that two interfaces of the hydraulic motor 3 are respectively connected with one of two interfaces on the same side of the electromagnetic valve 5, and the interfaces of the high-pressure energy accumulator 6 and the low-pressure energy accumulator 7 are respectively connected with one of two interfaces on the other side of the electromagnetic valve 5. Three connection states of the hydraulic motor 3 can be realized by reversing the electromagnetic valve 5: firstly, hydraulic oil in the high-pressure accumulator 6 flows to the hydraulic motor 3 and then flows to the low-pressure accumulator 7; secondly, all interfaces are closed; thirdly, hydraulic oil of the low-pressure energy accumulator 7 flows to the hydraulic motor 3 and then flows to the high-pressure energy accumulator 6; i.e. the solenoid valve 5 is used to control the flow direction of the hydraulic oil and the flow of the hydraulic oil, and the low pressure accumulator 7 provides the hydraulic auxiliary system 2 with hydraulic oil and pressure of the stabilizing system.
When in use, the transport vehicle is placed in a track of a railway locomotive wheel set maintenance system (the trolley is not filled with the high-pressure energy accumulator 6 when starting to work, whether the hydraulic starting condition is met or not is judged by detecting the pressure of the high-pressure energy accumulator 6, the hydraulic starting condition is met, the hydraulic starting condition is purely hydraulic, and the motor starting condition is not met), meanwhile, the wheels 12 of the transport vehicle for transporting the railway locomotive wheel set are connected with the coupling mechanism 4, and the wheel set is pushed by the pushing device 20 of the transport vehicle. When the transport vehicle starts, the flow direction of hydraulic oil is controlled by the electromagnetic valve 5, so that the direction of the hydraulic oil flowing through the hydraulic motor 3 is consistent with the rotation direction of the wheels 12. The hydraulic motor 3 is used as a hydraulic motor at this time, and the hydraulic auxiliary system 2 provides all power to drive the transport vehicle for transporting the railway locomotive wheel set, so that the current impact on the power supply when the transport vehicle for transporting the railway locomotive wheel set is started can be effectively avoided, and the service life of the power supply is prolonged. Similarly, when the transport vehicle accelerates, the high-pressure oil released by the high-pressure accumulator 6 drives the hydraulic motor 3 to rotate, thereby assisting acceleration.
When the transport vehicle brakes, the electromagnetic valve 5 is controlled to change direction, so that the direction of hydraulic oil flowing through the hydraulic motor 3 is opposite to the rotation direction of the wheels 12, and the kinetic energy of the transport vehicle is converted into hydraulic energy through the hydraulic motor 3 and stored in the high-pressure energy accumulator 6. That is, in this case, the hydraulic motor 3 is used as a hydraulic pump, the high-pressure accumulator 6 is charged, and the energy is recovered by the hydraulic motor 3. And simultaneously, a certain braking moment is provided to reduce the abrasion of a transport vehicle braking structure for transporting the railway locomotive wheel set. And finally, the railway locomotive wheel sets are sent to an overhaul area from the railway locomotive, so that labor is saved, and the working efficiency of workshops is improved. For the reversing of the electromagnetic valve 5 and the start-stop and control of a motor driving system, a PLC (programmable logic controller) is generally adopted for control, and a remote control device is matched for monitoring the transport vehicle; the information such as the battery state of the transport vehicle and possible fault information are displayed in real time through the remote control device, so that the personnel on duty can manage the information in a unified way.

The first propulsion mechanism 22 is provided with a fixing portion adapted to the wheel set for pushing the wheel set, preventing the wheel set from moving relative to the first propulsion mechanism 22 during pushing.
The first propulsion mechanism 22 may be lifted vertically or turned over; in this embodiment, in order to reduce the volume of the pushing device 20, the first pushing mechanism 22 is selectively lifted by turning over. Specifically, the first propulsion mechanism 22 includes a propulsion plate 28, one side of the propulsion plate 28 is hinged to one side of the propulsion device body 21, and the middle part is connected to the propulsion device body 21 through a linear driver.

Two V-shaped clamping blocks 29 are arranged on the inner side of the pushing plate 28, and the notches of the clamping blocks 29 are clamped outside the wheel pair shafts when the wheel pair is used. The first propulsion mechanism 22 is driven by a linear driver to lift, and can work when the wheel set needs to be propelled, and can be folded when the wheel set does not need to be propelled, so that the wheel set can return in the track conveniently, and the next wheel set can be propelled.
