Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As Figure 1-4, for an embodiment of a kind of fluid pressure type curb ditching machine of this utility model, including:
Car body 1, link 2 and milling dump 3, link 2 one end is connected with car body 1, the other end is dumped with milling and 3 is connected, milling is dumped and 3 is connected with fluid power system, car body drives milling to dump and 3 moves along curb, fluid power system drives milling to dump 3 rotations, completes trench digging action, and then has reached the purpose of curb ditching operation.
Fluid power system includes gear pump 4, hydraulic motor 5 and hydraulic oil container 6, is connected each through hydraulic oil pipe 7 between gear pump 4 with hydraulic motor 5, between hydraulic motor 5 and hydraulic oil container 6 and between gear pump 4 with hydraulic oil container 6, forms hydraulic oil circuit.
Gear pump 4 is connected with the output shaft of the driving device 8 on car body 1, driving fluid power system to operate by driving device 8, provide basic power for system, this attachment structure is simple, can complete to install without car body 1 inside is done bigger improvement, it is possible to be effectively improved the efficiency of loading and unloading.Hydraulic motor 5 dump with milling 3 cutter shaft 9 be connected, directly drive milling to dump 3 rotations.
It is additionally provided with overflow valve between hydraulic oil container 6 and hydraulic motor 5, plays the effect of overload protection.
The basic functional principle of native system is, driving device 8 driving gear pump 4, makes hydraulic oil rotate through the pressurize hydraulic motor 5 of rear drive cutter shaft 9 one end of gear pump 4,3 actions thus the milling with movable arbor 5 other end is dumped.When overburden, fluid is back to hydraulic oil container 6 through overflow valve, alleviates gear pump 4 and the oil pressure of hydraulic motor 5, plays the effect of overload protection.
In order to make full use of installing space, gear pump 4 and hydraulic oil container 6 are located on link 2, and link 2 side is located at by hydraulic motor 5.Hydraulic device structure is compacter, and then reaches the purpose of smooth working, reduces easy produced problem under the drive of drive system model, is effectively improved work efficiency.And owing to working media is fluid, operation can play lubrication voluntarily, extend the service life of ditching machine, reduce use cost.
Further, link 2 is hydraulic regulation formula link, including vehicle frame 11, connecting plate 12 and knife rest 13.Vehicle frame 11 front end is affixed with the trailing flank of connecting plate 12, and rear end is affixed with car body 1；Knife rest 13 rear end is hinged with the leading flank of connecting plate 12, and front end is hinged with cutter shaft 9, and knife rest 13 top is additionally provided with hydraulic jack 14, and the piston rod of hydraulic jack 14 is hinged with connecting plate 12, and cylinder body end is hinged with knife rest 13 front end.Car body 1 and critical piece can be played certain protective effect by connecting plate 12 in the course of the work, it is prevented that trench digging process medium stone splashes, and damages car body 1.The angle using hydraulic jack 14 cutter setting frame 13 is adjusted, so play lifting milling dump 3 purpose, this adjustment structure is simple, easy to use, regulates more accurate and flexible, reduces the weight of ditching machine further.
Gear pump 4 and hydraulic oil container 6 are located on vehicle frame 11, and knife rest 13 side is located at by hydraulic motor 5.Vehicle frame 11 may be designed to hollow type, conveniently installs hydraulic unit.
Use procedure:
Start car body 1 and driving device 8 thereof, regulate hydraulic jack 14 adjust milling dump 3 height, the power output shaft driven gear pump 4 making driving device 8 subsequently operates together, 4 hydraulic oil of gear pump of operating suck pressurization from hydraulic oil container 6 and send into hydraulic motor 5 by hydraulic oil pipe 7, hydraulic motor 5 starts running under high pressure liquid force feed effect, the hydraulic motor 5 band movable arbor 9 of operating and milling are dumped and 3 are rotated together, complete ditching operation.
The hydraulic adopted; volume is little, lightweight, inertia is little, compact conformation, stable working; by replacing gear train assembly to solve the problem that gear train assembly can not realize overload protection by Hydraulic Power Transmission System; alleviate total quality; increase durability; produced by power loss, heat can be taken away by the fluid flowed at work; thus avoiding producing excessive temperature rise at some local location of system; and it is easily achieved seriation, standardization, generalization, it is easy to manufacture and promote the use of.
