Description
Technical field
The present invention relates to Agricultural Machine Testing technical fields, are carried more particularly to one kind for detecting tractor hydraulic suspension
Rise the mechanism of device hoisting power.
Background technology
Tractor will carry out complete machine qualification detection before dispatching from the factory, and the detection of hydraulic lifting apparatus is a critically important ring
Section, in this link, worker mounts hydraulic cylinder and tractor by rod piece and chain.Traditional hanging mechanisms are
One metal round rod, rod piece both ends are inserted under tractor in the pin hole of pull rod, by metal hanger and liquid with chain among rod piece
Compressing cylinder is connected.Rod piece and chain need worker to raise, and add the working strength of worker.Round bar tends not to standard during mounting
, it is necessary to which worker operates repeatedly in the true lower stay rod pin hole of insertion, take considerable time, be unfavorable for the dilatory machine testing section of high rhythm
It claps.
The content of the invention
The present invention provides a kind of mechanism for being used to detect tractor hydraulic lifting device hoisting power, and the purpose is to solve to drag
In machine drawing qualification detection process, pull rod and hydraulic cylinder mount the problem of difficulty is big, and the consuming time is long under tractor.
The present invention includes hydraulic cylinder, slide, pulley, hydraulic cylinder upper end fixing device, hole cylinder pin, fan-shaped safety
Pin, Y shape mounting rod piece, dovetail groove and slot；
Y shape mounts rod piece and hydraulic cylinder and is formed a whole mechanism by hole cylinder pin and fan-shaped safe pin connection；
It can be moved freely on hydraulic cylinder equipped with pulley, hydraulic cylinder by pulley on slide；The telescopic end of hydraulic cylinder passes through solid
Determine device, hole cylinder pin and fan-shaped safety pin to be connected with Y shape mounting rod piece, hydraulic cylinder bottom is equipped with weight, hydraulic cylinder
It is vertical with slide when static；Y shape mounting rod piece top Liang Ge ends are respectively provided with dovetail groove, and slot is provided on the cell wall of dovetail groove
Hole.
The dovetail groove is in horn-like and big towards pull rod direction opening under tractor, the pull rod direction under tractor
It is open small.Inside dovetail groove along center line section be isosceles trapezoid.Inside dovetail groove along center line section be isosceles trapezoid；Slot
For round rectangle, the length of slot is twice of the width of slot, the pin hole diameter under the width and tractor of slot on pull rod
It is equal；The pin hole of slot and pull rod under tractor can be realized in the horizontal direction to be agreed with, the space energy that slot vertical direction is reserved
Adapt to the slight change of drawbar height under tractor.
The use process of the present invention：
Slide is placed in the melt pit at the tractor tailstock to be measured, and the concrete being screwed in melt pit is built on platform.It is sliding
Rail is parallel with ground residing for tractor to be measured, and the mechanism of hydraulic cylinder and Y shape mounting rod piece composition is sliding on slide by pulley
It is dynamic, keep as far as possible slot center and stay rod pin hole under tractor center point-blank.For different horsepower tractors
When the height change of lower pull rod is larger, it can be changed by the cooperation of the pin hole and pin for the fixing device for adjusting hydraulic cylinder upper end
Y shape mounts the height of rod piece.
The pin hole of pull rod moves substantially in sustained height along horizontal linear under slot and tractor on Y shape mounting rod piece
The mechanism, when dovetail groove with pull rod is in contact under tractor when, due under tractor pull rod can slight oscillatory, therefore tractor pull down
Bar can be suitable for drawbar height under tractor in automatic homing, the space that slot vertical direction is reserved under the extruding of dovetail groove slot arm
Slight change, stop moving mechanism when the pin hole of pull rod under slot and tractor agrees in the horizontal direction.Taper bolt is inserted
Enter in slot, and locked with safe annulus retainer ring, complete mounting operation.
The beneficial effects of the invention are as follows：
The present invention, which realizes, is not required worker to lift mounting rod piece, alleviates the working strength of worker, improves mounting behaviour
Safety coefficient when making.Semi-automatic rapid-aligning mounting can be achieved in the present invention, shortens the detection of tractor hydraulic device and hangs
The time expended when connecing is effectively guaranteed the detection efficiency of tractor factory testing, has stronger popularization and application value.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the present invention includes hydraulic cylinder 1, slide 2, pulley 3, hydraulic cylinder upper end fixation dress
Put 4, hole cylinder pin 5, fan-shaped safety pin 6, Y shape mounting rod piece 7, dovetail groove 8 and slot 9；
Y shape mounts rod piece 7 and hydraulic cylinder 1 and connects the machine that forms a whole by hole cylinder pin 5 and fan-shaped safety pin 6
Structure；It can be moved freely on hydraulic cylinder 1 equipped with pulley 3, hydraulic cylinder 1 by pulley 3 on slide 2；Hydraulic cylinder 1 stretches
End mounts rod piece 7 with Y shape by fixing device 4, hole cylinder pin 5 and fan-shaped safety pin 6 and is connected, and 1 bottom of hydraulic cylinder is equipped with
Weight, hydraulic cylinder 1 are vertical with slide 2 when static；7 top Liang Ge ends 14 of Y shape mounting rod piece are respectively provided with dovetail groove 8,
Slot 9 is provided on the cell wall of dovetail groove 8.
As shown in Figures 2 and 3, the dovetail groove 8 is in horn-like and big towards 11 direction opening of pull rod under tractor, the back of the body
11 direction opening of pull rod is small under tractor；Inside dovetail groove 8 along center line section be isosceles trapezoid；Slot 9 is round rectangle,
The length of slot 9 is twice of the width of slot 9, and the width of slot 9 is equal with the pin hole diameter on pull rod under tractor 11；Slot
The pin hole of hole 9 and pull rod under tractor 11 can be realized in the horizontal direction to be agreed with, and the space that 9 vertical direction of slot is reserved adapts to
The slight change of 11 height of pull rod under tractor.
The use process of the present invention：
As shown in figure 4, slide 2 is placed in the melt pit at 10 tailstock of tractor to be measured, it is screwed mixed in melt pit
Solidifying soil is built on platform.Slide 2 is parallel with ground residing for tractor 10 to be measured, the mechanism that hydraulic cylinder 1 and Y shape mounting rod piece 7 form
It is slided by pulley 3 on slide 2, keeps the center of slot 9 and the center of 11 pin hole of pull rod under tractor straight at one as far as possible
On line.For pull rod 11 under different horsepower tractors height change it is larger when, can be by adjusting consolidating for 1 upper end of hydraulic cylinder
The cooperation for determining the pin hole and pin of device 4 changes the height of Y shape mounting rod piece 11.
As shown in Figure 5 and Figure 6, Y shape mounts the pin hole of pull rod 11 under the slot 9 and tractor on rod piece 7 substantially same
Highly, the mechanism is moved along horizontal linear, when dovetail groove 8 is in contact with pull rod under tractor 11, due to pull rod under tractor
11 can slight oscillatory, therefore under tractor pull rod 11 can under the extruding of 8 slot arm of dovetail groove automatic homing, 9 vertical direction of slot it is pre-
The space stayed is suitable for the slight change of 11 height of pull rod under tractor, when the pin hole of pull rod 11 under slot 9 and tractor is in water
Square to stopping moving mechanism when agreeing with.Taper bolt 12 is inserted into slot 9, and it is locked with safe annulus retainer ring 13.It completes to hang
Connect operation.
