Technical field
The utility model relates to a kind of mountainous region crawler tractor tensioning apparatus based on accumulator, belongs to agricultural mechanical technology
Field.
Background technique
Track takeup is mountainous region crawler tractor normal walking, the essential component of steady operation.Currently, on mountain
In terms of ground crawler tractor, the more extensive track takeup of application have spring crawler tensioning, screw crawler tensioning and
Hydraulic track tensioner, spring crawler tensioning and screw crawler tensioning when in use, trivial operations, and crawler belt is easy
Band；Hills are with a varied topography, ground relief, and traditional hydraulic track tensioner cannot effectively buffer road surface height and rise
Hydraulic shock brought by lying prostrate, it is big to the damage of Hydraulic Elements, and it is unable to absorption pressure pulsation, it cannot automatically adapt to be tensioned
Amount.Therefore, it is badly in need of developing a kind of novel hydraulic track tensioner device.
Summary of the invention
It is unable to absorption pressure pulsation and buffering hydraulic during the work time to solve traditional hydraulic track tensioner device
The problem of impact, the utility model provide a kind of mountainous region crawler tractor tensioning apparatus based on accumulator.The utility model
Structure is simple, is swift in motion, is quick on the draw, the operation is stable.
To achieve the above object, the utility model uses following technical scheme:
A kind of mountainous region crawler tractor tensioning apparatus based on accumulator, specifically includes that tensioning hydro-cylinder, pressure gauge, accumulation of energy
Device, manual pressure device and hydraulic oil pipe.
It is characterized by:
The tensioning hydro-cylinder is plunger case；
The accumulator is diaphragm accumulator；
The tensioning hydro-cylinder, pressure gauge, accumulator and manual pressure device are connected in series by hydraulic oil pipe；
The manual pressure device includes fixed-hinged support, lever, piston rod, piston, cylinder barrel, oil outlet one-way valve, oil inlet
Check valve and fuel tank；The fixed-hinged support and cylinder barrel position are relatively fixed；Described lever one end hingedly connects with fixed-hinged support
It connects；Described piston rod one end and lever are articulated and connected, and the other end and piston are connected；The piston can be transported up and down along inner wall of cylinder
It is dynamic；The oil outlet one-way valve is connected with cylinder barrel by hydraulic oil pipe；The in line check valve by hydraulic oil pipe respectively with cylinder barrel,
Fuel tank connection.
The utility model has the following beneficial effects:
1, the utility model structure is simple, is swift in motion, is quick on the draw, the operation is stable；
2, the utility model can absorption pressure be pulsed, buffering hydraulic impacts, and keeps system constant pressure, realizes crawler tractor
Stabilized walking.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1. tensioning hydro-cylinders；2. pressure gauge；3. accumulator；4. manual pressure device；41. fixed-hinged support；42. thick stick
Bar；43. piston rod；44. piston；45. cylinder barrel；46. oil outlet one-way valve；47. in line check valve；48. fuel tank；5. hydraulic oil pipe.
Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
A kind of mountainous region crawler tractor tensioning apparatus based on accumulator, specifically includes that tensioning hydro-cylinder (1), pressure gauge
(2), accumulator (3), manual pressure device (4) and hydraulic oil pipe (5).
It is characterized by:
The tensioning hydro-cylinder (1) is plunger case；
The accumulator (3) is diaphragm accumulator；
The tensioning hydro-cylinder (1), pressure gauge (2), accumulator (3) and manual pressure device (4) are gone here and there by hydraulic oil pipe (5)
Connection connection；
The manual pressure device (4) includes fixed-hinged support (41), lever (42), piston rod (43), piston (44), cylinder
Cylinder (45), oil outlet one-way valve (46), in line check valve (47) and fuel tank (48)；The fixed-hinged support (41) and cylinder barrel (45) position
It sets relatively fixed；Described lever (42) one end and fixed-hinged support (41) are articulated and connected；Described piston rod (43) one end and lever
(42) it is articulated and connected, the other end and piston (44) are connected；The piston (44) can move up and down along cylinder barrel (45) inner wall；It is described go out
Oily check valve (46) and cylinder barrel (45) are connected by hydraulic oil pipe (5)；The in line check valve (47) passes through hydraulic oil pipe (5) point
It is not connect with cylinder barrel (45), fuel tank (48).
The working principle of the utility model are as follows: in the specific implementation, tensioning hydro-cylinder is in retracted mode to the utility model, leads to
Manual presses lever is crossed, piston rod and piston is driven to move up and down along inner wall of cylinder, hydraulic oil enters cylinder barrel through in line check valve
Inside, then enter hydraulic oil pipe through oil outlet one-way valve；At this time since accumulator internal pressure is larger, hydraulic oil does not enter accumulation of energy
Device；Hydraulic oil enters in pressure gauge by hydraulic oil pipe, and pressure gauge shows the pressure of hydraulic oil in oil pipe, can be convenient user
It can be visually seen pressure；Hydraulic oil enters tensioning hydro-cylinder simultaneously, and crawler tensioning is realized in tensioning hydro-cylinder work.
When crawler tractor walking in mountainous region is at rough road surface, road surface brings hydraulic shock to tensioning apparatus,
Hydraulic oil overpressure sharply increases at this time, and the pressure in hydraulic oil pipe is greater than the pressure inside accumulator, and hydraulic oil passes through liquid
Pressuring oil pipe enters accumulator, and accumulator absorbs hydraulic shock and pressure fluctuation, ensure that system constant pressure, and tensioning hydro-cylinder keeps former
First stretching state, realizes the stabilized walking of crawler tractor.
The structure & working mechanism of the utility model is explained with specific embodiment above, the utility model does not limit to
It is all any modifications made on the spirit of the present invention and principle, same according to above-mentioned description in above embodiments
Deng replacement and improvement etc., should be included within the scope of protection of this utility model.
