Description

Technical Field

[0001] The utility model relates to a speed governor maintenance device for a diesel engine of an internal combustion locomotive, belonging to the technical field of speed governor maintenance. Background Art

[0002] The overall structure of the diesel locomotive speed governor is relatively complex. It is a mechanical structure that integrates mechanical, electrical and hydraulic functions. It weighs 50kg and has no gripping points on the surface. It is very difficult for two workers to lift it. When the diesel locomotive is undergoing factory repairs, overhauls and minor repairs, the speed governor needs to be disassembled for inspection and repair. The speed governor needs to be fixed in the correct position for disassembly and assembly. The oil must be drained and the appearance must be cleaned before disassembly. It needs to be disassembled layer by layer from top to bottom, and assembled layer by layer from the base, lower body, middle body and upper body. Due to the small clearance of the internal structure of the speed governor, for example, the clearance between the slide valve and the middle body is 0.055mm, so it is difficult to disassemble and assemble during inspection. The oil channels of the speed governor also need to be purged with high-pressure air and the site must be clean and tidy. When overhauling the speed governor, all springs, holes, plungers and pistons need to be measured. The oil storage chamber spring and servo motor spring need to be disassembled and overhauled. These two groups of springs have high working precision and strong elasticity. Excessive compression or bias pressure can easily damage them. Therefore, disassembly and installation must be completed at one time. During the period, it is necessary to prevent slippage and injury, and to avoid damage to the spring. Due to different speed governor models, the height of the speed governor body and the servo motor are different, and the working height of the speed governor disassembly and assembly machine needs to be adjusted. After assembly, check whether the oil supply pressure of the assembled speed governor oil pump can reach 883±50 kPa, and adjust the parameters such as low speed 500r / min, 30min, high speed 1000r / min, 20min. The overhaul of the diesel locomotive diesel engine speed governor requires hoisting, cleaning, disassembly, measurement, assembly, running-in and debugging.

[0003] The existing technology has a single function for the tooling for inspecting the speed governor of a diesel locomotive. For example, Chinese patent ZL2022106492432 "A device and method for measuring the oil pressure of a combined speed governor" can only test the oil pressure of the speed governor, and Chinese patent ZL2018214829733 "A lifting structure for a locomotive diesel engine speed governor" is only convenient for lifting the speed governor. Due to the lack of a fully functional special tooling, it is not convenient to carry out the lifting, cleaning, disassembly, assembly and other operations of the speed governor of a diesel locomotive, the work intensity is high, the maintenance period is long, the repair quality is poor, and there are many safety hazards.

[0021] In order to solve the problem of safe disassembly and assembly of springs during the maintenance of the speed governor of a diesel locomotive, a speed governor spring disassembly and assembly machine 3 is arranged on a workbench 4. A fixed column 29 is welded on the workbench 4, and a lifting rack 27 is inlaid on the fixed column 29. The lifting rack 27 is meshed with the lifting sleeve 31, and the overall height adjustment function is realized by operating the lifting crank 25.

The utility model classifies and stores a variety of tools, gauges, and spare parts needed for speed regulator maintenance, which can effectively reduce unnecessary damage caused by collisions between them due to improper storage.

[0024] The speed regulator itself weighs 50kg, and the existing technology requires 2 workers to assemble and disassemble the speed regulator, which takes an average of 20 hours. However, with the utility model, only 1 worker is needed to complete the same work, which takes an average of 12 hours, and the efficiency is improved by 50%, achieving the expected goal.

[0025] The lifting arm 1 can rotate 360° horizontally. Using the electric hoist 2, a single person can easily place the speed governor on the speed governor disassembly storage rack or remove it from the speed governor assembly and debugging base, thus avoiding property loss and personal injury caused by the staff carrying the speed governor. The speed governor assembly and debugging base can adjust the parameters of the assembled speed governor, such as whether the oil pump supply pressure can reach 883±50 kPa, low speed 500r / min, 30min, high speed 1000r / min, 20min, etc.

[0026] In the embodiment, referring to the appendages 1, 2, and 3, the workbench 4, the measuring tool box 8, the spare parts box 9, the tool box 10, and the storage box 11 form a workbench box body, the speed regulator spring disassembler 3 is arranged on the workbench 4, the lifting arm 1 is connected to the speed regulator spring disassembler through the lifting arm rotating mechanism and can realize 360° horizontal rotation, the lifting arm 1 is designed with a linear slideway, the electric hoist 2 can slide easily on the lifting arm, and the speed regulator is lifted or placed on the speed regulator disassembly storage rack and the speed regulator assembly and debugging base. The speed regulator 15 to be repaired is first fixed on the speed regulator disassembly storage rack 14 to drain and clean, and the speed regulator oil collection tray 13 can collect the discharged dirty oil or the cleaned dirty oil through the pipeline into the waste oil collection barrel in the storage box 11, and then the speed regulator is disassembled step by step on the speed regulator disassembly storage rack; before assembly, it is necessary to blow the various parts and oil channels of the speed regulator, and a blow gun quick interface 12 is designed on the workbench box body.

[0027] Disassembly and assembly of the speed regulator spring: First, rotate the worm crank 24 to the highest position, and then shake the lifting crank 25 according to the height of the speed regulator workpiece 30, adjust the height of the lifting sleeve 31 to the appropriate position, and place the speed regulator workpiece 30 on the workbench 4, so that the spring cover of the oil storage chamber of the speed regulator is aligned with the vertical position of the ball screw 26, and confirm whether the spring pressure head 28 is aligned with the disassembly and assembly of the oil storage chamber spring cover. Shake the worm crank 24, and the spring pressure head 28 is fastened to the oil storage chamber spring cover. Continue to shake the worm crank 24 until the spring is detached from the spring cover, remove the spring, and slowly shake the worm crank 24 in the opposite direction to release the spring to the fully relieved position, completing the spring disassembly process, and the assembly steps are reversed.

[0028] The connection fixing plate 19 of the speed regulator assembly and debugging base 7 is fixedly connected to the workbench 4 through the fixing bolt hole 20. When assembling the speed regulator, in order to smoothly align the speed regulator's speed gear with the speed regulator's speed plate correctly, and to make the preload force of the middle and lower body devices of the speed regulator uniform, a manual mechanism is designed. The hand crank 23 is designed to be plug-in and ready-to-use. When necessary, the hand crank 23 is rotated to drive the hand crank output gear 33 to realize the rotation of the speed regulator main shaft.

The assembly quality of the lower and middle body devices of the speed regulator is judged by the flexible rotation of the speed regulator's slide valve device. In order to test the working oil pressure of the speed regulator oil pump and the speed regulator running-in test, an electric mechanism is designed.
