Specifically, fig. 6, 7 and 8 are communication diagrams of two oil transportation modes. Since the working principle of the cab lifting cylinder is conventional, fig. 8 is a simple diagram illustrating the manner of filling oil into the lifting cylinder according to the present invention, and the others are omitted. As can be seen from fig. 8, when the oil outlet joint 11 is filled with oil, the oil return joint 12 returns oil, whereas when the oil return joint 12 is filled with oil, the oil return joint 11 returns oil, and through these two forms, the back and forth movement of the piston 53 is completed, so that the lifting or lowering of the cab lifting cylinder 52 is completed.
The plunger oil hole 18 is an oil outlet at the bottom end of the plunger channel 49, the plunger 22 is inserted into the plunger channel 49 from the upper end of the plunger channel 49, an empty groove is formed in the middle outside the top end of the upper section 17 of the plunger cylinder, the buffer spring 20 is placed in the empty groove, the supporting ball 21 is placed on the upper surface of the buffer spring 20, the inclined flat pad 16 is placed at the top of the supporting ball 21, the supporting ball 21 serves as a spherical supporting body, the inclined flat pad 16 is guaranteed to swing by taking the inclined flat pad as a central support, the inclined flat pad 16 can be guaranteed to keep an inclined shape no matter how the inclined flat pad 16 swings, namely, the circular inclined flat pad 16 is always high at one end bottom by taking the supporting ball 21 as the center, and the inclined flat pad can be in the inclined state no matter how the inclined flat pad rotates. The buffer spring 20 is a buffer function for ensuring that the downward force of the inclined flat cushion 16 during the rotation process is not too rigid, i.e. the service life of the inclined flat cushion 16 and the support ball 21 is ensured. In order to ensure that the inclined flat cushion 16 always keeps centering on the supporting ball 21, a groove matched with the top spherical surface of the supporting ball 21 can be formed in the middle of the inclined flat cushion 16. The upper end of the plunger 22 passes through the inclined flat pad 16 and is clamped by a plunger chuck 46 at the top end of the plunger 22, and the plunger chuck 46 is a limit position which ensures that the three plungers 22 can not be separated from the inclined flat pad 16 no matter how the inclined flat pad 16 rotates. The top of the plunger chuck 46 is provided with an inclined crankshaft, the upper end of the inclined crankshaft is connected with a motor shaft 39 of the motor 2, the plunger 22 really moves downwards to form the inclined crankshaft, the inclined crankshaft and the inclined flat pad 16 keep consistent inclination no matter how the inclined crankshaft rotates, and the inclined crankshaft repeatedly applies downward force to the three plungers 22 through the bottom end one by one in sequence, so that oil injection is completed. From this section, it can be seen that the inclined crankshaft functions as a power application component, while the inclined flat pad 16 functions as both a support and a limit. The working structure of the upper part of the plunger pump is shown in the section, and as can be seen from fig. 2, 3 and 5, a motor shaft 39 of the motor 2 can drive an inclined crankshaft with one surface higher than the other surface and one bottom to rotate, an inclined flat pad 16 corresponds to the inclined crankshaft, the inclined crankshaft and the inclined flat pad 16 have the same inclination and the same movement track; the top ends of the three plungers 22 are always contacted with the lower part of the inclined crankshaft, but due to different heights, the three plungers 22 can work in a reciprocating mode and are pressed into the plunger channel 49 to be in a working state, and the other two plungers are basically in a standby working state. The plunger 22 to be in the working state is reset by the recoil force of the oil pressure in the plunger channel 49, and the recoil force is not larger than the rebound force of the plunger oil check spring 37 at the bottom end of the plunger channel 49.
An oil return groove 50 is formed in the outer edge of the part, inserted into the base 14, of the straight valve element 13, the oil return groove 50 is respectively communicated with an oil return channel 51, the oil outlet pipe joint 11 and the oil return pipe joint 12, and the oil return channel 51 is communicated with the main oil pipeline 41. The straight valve core 13 is used as a regulating mechanism for regulating the direction in which the oil in the oil passage 25 of the straight valve core is injected into the cab lifting cylinder, when the oil needs to be injected into the right cylinder, the oil is injected into the oil return pipe joint 12, so that the cylinder plug 53 moves, and the oil of the left cylinder enters the oil return passage 51 through the oil outlet pipe joint 11 and the oil return groove 50 (the specific structure is shown in fig. 7). When oil needs to be filled into the left cylinder of the cab lifting cylinder, the straight valve core 13 is rotated, so that the oil channel 25 of the straight valve core is communicated with the oil outlet pipe joint 11, the cylinder plug 53 moves rightwards at the moment, oil in the right cylinder enters the oil return channel 51 through the oil return pipe joint 12 and the oil return groove 50 (the specific structure is shown in figure 6), and through the part, the oil outlet pipe joint 11 and the oil return pipe joint 12 only can ensure that one is communicated with the oil channel 25 of the straight valve core, and the other is communicated with the oil return groove 50.
The invention has an oil filter screen 19 at the bottom end 30 of the plunger oil chamber 31. The filter screen 19 is used for filtering impurities in the grease entering the circulating system and preventing the oil circuit from being blocked by the impurities.
The inclined crankshaft of the present invention is divided into an upper crankshaft 24 and a lower crankshaft 47, and the upper crankshaft 24 and the lower crankshaft 47 are connected by a roller bearing 23. The oblique crankshaft is arranged into two parts, and the rollers are added between the oblique crankshaft and the oblique crankshaft, similar to the principle part of the bearing, the oblique crankshaft is ensured to be in a locking state when rotating, if the lower crankshaft 47 is locked, the roller bearing 23 and the upper crankshaft 24 are repeatedly pressed through position adjustment, the lower crankshaft 47 is ensured to continuously rotate to press the plunger 22, and the mechanism is proved to be adjusted quickly through repeated experiments even if the lower crankshaft 47 is in the locking state.
The process of the oil of the invention is as follows: the oil tank 1 → the oil tank port 40 → the main oil line 41 → the plunger oil inlet 42 → the bottom end 30 of the plunger oil chamber 31 → the connecting passage 32 → the plunger passage 49 → the plunger oil cross passage 29 → the first transition oil passage 38 → the transition oil outlet 43 → the second transition oil passage 26 → the straight spool oil passage 25, and finally, the oil enters the oil outlet pipe joint 11 or the oil return pipe joint 12 as determined by the adjustment of the straight spool 13. The oil return flow is as follows: the oil outlet pipe joint 11 or the oil return pipe joint 12 → the oil return groove 50 → the oil return passage 51, at the junction of the oil return passage 51 and the main oil pipe 41, the oil is divided into two paths, the first path is converged with the main oil pipe 41 and is sent into the plunger oil chamber 31 through the plunger oil inlet 42, and the other path is converged with the oil stored in the main oil pipe 41 and returns to the oil tank 1 when the plunger oil chamber 31 is full.
