Fig. 1 and 2 show a schematic structural diagram of an intelligent lifting control system of a tractor unit, which comprises a gear pump 1, a multi-way valve 6, a lifter 8 and a double-acting lifting oil cylinder 10. The gear pump 1 is connected with an oil inlet of the multi-way valve 6 through an oil outlet pipe, an oil outlet of the multi-way valve 6 is respectively connected with oil inlets of two double-acting lifting oil cylinders 10, and the two double-acting lifting oil cylinders 10 are connected with rocker arms of the lifter 8. Specifically, the multi-way valve 6 provides a plurality of oil outlets, wherein 1 to 3 oil outlets are provided with quick change connectors for hydraulic output, and the other 1 oil outlet is simultaneously connected with oil inlets of two double-acting lifting oil cylinders 10 to provide hydraulic energy for a hydraulic lifting system. Oil outlets of the two double-acting lifting oil cylinders 10 are connected with the multi-way valve 6 through oil pipes, and oil returns to an oil tank through an oil return pipe to form an oil circulation loop.
The system further comprises a multi-way valve operating handle 5, the multi-way valve operating handle 5 is connected with a valve rod of the multi-way valve 6 through a flexible shaft, so that the multi-way valve operating handle 5 is pulled to control the hydraulic output of the multi-way valve 6, two double-acting lifting oil cylinders 10 are controlled to support the rocker arms of the lifter 8 to lift the lifting suspension 11 connected with the rocker arms to work, and then the lifting machine C is lifted. The system further comprises a clutch operating handle 4, the clutch operating handle 4 being connected to the double acting clutch 3 by a hose to control the disengagement of the double acting clutch 3. The power of the engine is transmitted to the power output shaft 12 by the clutching of the double-acting clutch 3.
Fig. 3 shows a top view of a lifter of the intelligent lifting control system of the tractor unit provided by the invention. The lifter 8 comprises a lifter housing 81 and lifting rocker arms 82 symmetrically arranged on two sides of the lifter housing 81, and the two lifting rocker arms 82 are respectively connected with a height limiting feedback bracket 13 and a power output clutch control flexible shaft bracket 14. The lifter housing 81 is connected to the upper end of the gearbox of the tractor, the lifting rocker 82 is connected to the double-acting lifting cylinder 10, and the lifting and descending actions of the lifting rocker 82 are realized by the action of the double-acting lifting cylinder 10.
The system also comprises a lifting height feedback rod 7, and a positioning bolt is arranged on the lifting height feedback rod 7. One end of the lifting height feedback rod 7 is connected with the multi-way valve operating handle 5, and the other end of the lifting height feedback rod passes through a connecting hole on the height limiting feedback bracket 13 of the lifter 8 and is limited by a positioning bolt, so that when the double-acting lifting oil cylinder 10 lifts the lifting rocker arm 82 to the limit of the positioning bolt, the lifting height feedback rod 7 is driven to stop the lifting action controlled by the multi-way valve operating handle 5, and then the multi-way valve 6 is controlled to disconnect the hydraulic oil supply of the double-acting lifting oil cylinder 10. That is, the lifting height of the lifter 8, i.e., the machine tool C, is set by adjusting the position of the set bolt on the lifting height feedback lever. Specifically, the other end of the lifting height feedback rod 7 penetrates through a connecting hole in the height limiting feedback bracket 13, and a positioning bolt is respectively arranged on two sides of the connecting hole, so that the lifting height feedback rod 7 can slide in the connecting hole within a certain distance range.
The system also comprises a power output clutch control flexible shaft 9, one end of the power output clutch control flexible shaft 9 is connected with the double-acting clutch 3, and the other end is connected with a power output clutch control flexible shaft bracket 14 of the lifter 8. When the lifting height is set, the height limit feedback bracket 13 connected to one side of the lifting rocker arm drives the lifting height feedback rod 7 to feed back and stop the action, and meanwhile, the power output clutch control flexible shaft bracket 14 connected to the other side of the lifting rocker arm drives the power output clutch control flexible shaft 9 to pull the double-acting clutch 3 to disconnect the power of the clutch, so that the power output shaft 12 is disconnected, and the linkage control of the lifting height and the power output is realized.
When the clutch operating handle 4 is in the pull-up position, the power output clutch control flexible shaft 9 does not act on the double-acting clutch 3, the double-acting clutch 3 does not have power transmission to the power output shaft 12, and at the moment, the multi-way valve operating handle 5 is operated to lift and lower the implement C under the condition of no power output.
When the clutch operating handle 4 is in the down position and the multi-way valve operating handle 5 is in the down position, the double-acting clutch 3 is engaged to transmit power to the power output shaft 12, and the power output shaft 12 drives the machine tool C to operate through the transmission shaft B.
When the clutch operating handle 4 is at the put-down position and the multi-way valve operating handle 5 is at the lifting position, oil enters the lower cavity of the double-acting lifting oil cylinder 10 through the multi-way valve 6, and drives the lifter 8 to drive the lifting suspension 11 to lift the implement C upwards. When the implement C reaches the lifting height set by the lifting height feedback rod 7, the lifting height feedback rod 7 connected to the height limit feedback bracket 13 of the lifter 8 applies a thrust to the multi-way valve operating handle 5, so as to control the multi-way valve 6 to stop supplying oil to the double-acting lifting cylinder 10, and the lifting action stops to stop the implement C at the set height. Meanwhile, a power output clutch control flexible shaft 9 connected with a power output clutch control flexible shaft bracket 14 of the lifter 8 pulls the double-acting clutch 3 to be disconnected, so that the power output shaft 12 stops rotating. At this time, the transmission shaft B and the power output shaft 12 form an included angle a, which is a safe included angle for setting the power output shaft 12 to be disconnected, so that the linkage of the lifting action and the power output is realized. The lifting height of a lifting suspension 11 lifting machine C can be set by adjusting a positioning bolt on a lifting height feedback rod 7, and the stroke of the power output clutch control flexible shaft 9 for pulling the double-acting clutch 3 is adjusted to realize the separation of the double-acting clutch 3, so that the power output shaft 12 is disconnected.
When the clutch operating handle 4 is in the down position and the multi-way valve operating handle 5 is operated to move downwards, oil enters the upper cavity of the double-acting lifting oil cylinder 10 through the multi-way valve 6, so that the lifter 8 drives the lifting suspension 11 to lower the machine tool C. At this time, the power output clutch control flexible shaft 9 connected with the power output clutch control flexible shaft bracket 14 of the lifter 8 releases the double-acting clutch 3 to enable the double-acting clutch to be engaged, so that the power output shaft 12 starts to drive the machine tool C to work, and the machine tool C starts to work by engaging the power output shaft 12 while the machine tool C is put down.
The above examples are only for illustrating the technical solutions of the present invention, and are not intended to limit the scope of the present invention. But all equivalent changes and modifications within the scope of the present invention should be considered as falling within the scope of the present invention.
