Description

Technical Field

[0001] The utility model relates to a speed governor assembly and debugging base used when disassembling and repairing a railway diesel locomotive, belonging to the technical field of diesel locomotives. Background Art

[0002] The speed governor of a diesel locomotive is a mechanical structure with a very complex overall structure, integrating mechanical, electrical and hydraulic functions. Diesel locomotives are divided into factory repair, overhaul, minor repair and auxiliary repair. The first three repair processes require the speed governor to be disassembled and repaired. Since the speed governor needs to be fixed in position during maintenance, it needs to be disassembled layer by layer from top to bottom. When assembling, it needs to be assembled layer by layer from the base, lower body, middle body and upper body. In addition, the internal structure has a small clearance, such as the clearance between the slide valve and the middle body is 0.055mm. Therefore, both the disassembly and assembly of the maintenance need to be carried out on a special maintenance stand. In addition, the direction of the transmission shaft needs to be constantly adjusted for both disassembly and assembly to ensure that the internal components can enter the corresponding position. After assembly, the transmission shaft needs to be rotated to detect whether the oil supply pressure of the assembled speed governor oil pump can reach 883±50 kPa, and the low-speed (500r / min, 30min) and high-speed (1000r / min, 20min) parameters need to be adjusted. Since there is no dedicated governor assembly and debugging device at present, the assembly and debugging of diesel locomotive governors is very difficult, which greatly reduces the maintenance efficiency of the governors.

[0016] The utility model provides a tooling device for repairing the speed governor of a diesel locomotive. The device has a compact structure and is designed with two upper and lower connection plates. It can be installed on any repair platform or on a movable cart, meeting the needs of the speed governor repair site. The device is designed with an electric rotating mechanism and a manual rotating mechanism. The function of the manual rotating mechanism is to facilitate the assembly of the lower body, middle body and upper body of the speed governor, so that the oil pump gear and the spline shaft can be smoothly aligned, ensuring that the slide valve and the slide valve sleeve are not damaged, ensuring that the speed gear can be safely aligned with the buffer plate gear, and at the same time facilitating the safe assembly of other rotating parts; the electric rotating mechanism mainly plays the role of adjusting the speed, inspecting the oil pump and draining after the speed governor is assembled. The utility model well solves the problems of the difficulty of aligning the speed plate and the speed gear during the repair of the speed governor of a diesel locomotive, as well as the inconvenience of the speed governor running-in test, oil pressure detection and running-in test.

[0017] See also Figure 1 and Figure 2 The utility model mainly includes a base bolt 2, a mounting base 3, an upper connecting plate 4, a speed regulating push rod 6, a motor controller 7, a motor control line 8, a hand crank 9, a body 10, a speed regulating motor 11, a motor connecting flange 12, a bearing 13, a hollow spline shaft 14, a spline shaft driving gear 15, a motor output gear 16, a crank output gear 17, a crank mounting seat 18, and a lower connecting plate 19.

[0018] The upper connecting plate 4 and the lower connecting plate 19 are fixed to the top and bottom of the body 10 respectively. The lower connecting plate 19 is fixed to the maintenance cart or maintenance platform by bolts, and the upper connecting plate 4 can be fixed under the maintenance platform through the bolt holes 5.

[0019] The mounting base 3 is fixed on the upper part of the upper connecting plate 4, and the speed regulator 1 is fixed on the upper part of the mounting base 3 by the base bolts 2. The mounting base 3 is provided with a positioning groove matching the speed regulator 1 for centering the spline shaft of the speed regulator.

[0020] The power is transmitted inside the body 10 through three cross shafts (hollow spline shaft 14, transmission shaft of speed regulating motor 11, central axis of crank output gear 17), and the transmission gears of the three shafts (spline shaft drive gear 15, motor output gear 16, crank output gear 17) are fan gears.

[0021] The hollow spline shaft 14 is vertically installed inside the vertical holes of the mounting base 3, the upper connecting plate 4 and the body 10 and is rotatably connected to the body 10 through the bearing 13. The spline shaft driving gear 15 is fixed to the lower end of the hollow spline shaft 14 and is integrally formed with the spline shaft driving gear 15. The shape of the center hole of the hollow spline shaft 14 matches the spline shaft of the speed regulator.

[0022] The speed regulating motor 11 is fixed to the machine body 10 via a motor connecting flange 12 , and the motor output gear 16 is meshed with the spline shaft driving gear 15 and connected to the speed regulating motor 11 via a transmission shaft.

[0023] The crank output gear 17 is meshed with the spline shaft driving gear 15, the central axis of the crank output gear 17 is rotatably connected to the body 10 through a bearing, the crank mounting seat 18 is fixedly connected to the central axis of the crank output gear 17, and a slot matching the end of the hand crank 9 is provided on the crank mounting seat 18. The hand crank is detachable, and when the spline shaft of the speed regulator needs to be rotated manually, the hand crank 9 is inserted into the slot on the crank mounting seat 18, and the hand crank 9 is rotated manually. After completion, the hand crank 9 is removed to prevent the hand crank from injuring people when the speed regulating motor 11 rotates.

[0024] The motor controller 7 is mounted on the machine body 10 and connected to the speed regulating motor 11 through the motor control line 8. The speed of the speed regulating motor 11 can be controlled by operating the speed regulating push rod 6 on the motor controller 7. The motor controller 7 is designed with stop, 500 rpm, and 1000 rpm indicators to facilitate the adjustment of the operating parameters of the speed regulating motor.

[0025] The utility model utilizes the lower connecting plate 19 to be fixed on the maintenance platform or the maintenance vehicle, and the speed governor spline shaft on the speed governor 1 is aligned with the center hole of the hollow spline shaft 14 and slowly inserted, and the speed regulating motor 11 can be started to drive the spline shaft to rotate at a low speed to realize the spline shaft centering installation. It is important to ensure that the installation must be in place, and the base bolts 2 are tightened after ensuring that the speed governor falls into the positioning groove on the installation base 3.

[0026] Reference Figure 2When assembling the speed regulator, in order to make the speed gear and the speed disc correctly align and the preload force of the middle body and the lower body be uniform, the utility model designs a manual rotating mechanism consisting of a hand crank 9, a crank output gear 17 and a crank mounting seat 18. The crank output gear 17 is driven to rotate by the hand crank 9, which drives the spline shaft driving gear 15 and the hollow spline shaft 14 to rotate, so that the spline shaft of the speed regulator rotates slowly and drives the speed disc of the slide valve device to move, so that it is correctly aligned with the speed gear. When assembling the middle body and the lower body, since the gap between the slide valve device and the slide valve hole of the middle body is 0.055mm, the center line position of the slide valve device and the slide valve hole must be ensured. In the process of assembling and preloading the 8 8mm bolts of the lower body, the hand crank must also be operated to slowly rotate the spline shaft of the speed regulator to drive the slide valve device to rotate. The assembly quality of the lower body and the middle body can be judged by the flexible rotation of the slide valve device.

[0027] After the speed regulator is assembled, in order to test the working oil pressure of the speed regulator oil pump and conduct the speed regulator running-in test, the utility model designs an electric rotating mechanism composed of a motor controller 7, a speed regulating motor 11, a motor connecting flange 12, and a motor output gear 16. Push the speed regulating push rod 6 of the motor controller 7 to a suitable position to make the speed regulator rotate at the required speed, and check whether the working oil pressure of the assembled speed regulator is 883±50 kPa. After the speed regulator moving elements are assembled, gradually speed up to the minimum speed, adjust the speed regulator minimum speed stop pin, and complete the speed regulation assembly.

[0028] The utility model drives the speed regulator to run through the electric rotating mechanism to carry out oil pressure test and running-in test.
