Description
Technical field
The utility model relates to a kind of Lifting Technique fields, more particularly, to a kind of four oil cylinder synchronous lifting mechanisms.
Background technique
Fully loaded/No Load Ratio of medium and heavy goods stock is much larger than car and passenger car, by axle load and rack attachment coefficient
Limitation, the maximum braking force that brake can issue when zero load detection is difficult to reflect charge of trucks or full load condition, zero load detection
Qualification, loads or fully loaded detection is not necessarily qualified.GB21861-2014(Vehicle Security examines project and method) regulation:
For examine multiaxis and and fill the drum reaction brake test bench of axis vehicle, should have stage body lifting function, to realize vapour
The load detection of vehicle braking ability rack.The mode of rack lifting at present mainly passes through air-powered lifting, and lifting force is smaller, stability
Poor, there is room for improvement.
Utility model content
The purpose of the utility model is to provide a kind of to mention rack with being effectively increased by way of hydraulic pressure lift
The four oil cylinder synchronous lifting mechanism of one kind of the effect risen.
The above-mentioned purpose of utility model of the utility model has the technical scheme that
A kind of four oil cylinder synchronous lifting mechanisms including outer framework, the oil cylinder being mounted on above outer framework bottom surface, are located at oil cylinder
The platform of top and above platform with flexible to realize that platform raising is synchronous with decline up and down for controlling oil cylinder
Valve.
By using above-mentioned technical proposal, the liter to platform can be effectively realized by oil cylinder and with the control of paces
Drop improves the effect to rack lifting.
The utility model is further arranged to: four oil cylinder synchronous lifting mechanisms further include be symmetrically disposed on above outer framework and
Be placed in platform two sides position-limited rack and the limitting casing above position-limited rack, be provided on platform in the limitting casing
The idler wheel of balance is kept in lower motion process.
By using above-mentioned technical proposal, it is arranged by position-limited rack, limitting casing and the idler wheel in limitting casing effective
Improve stability when platform moves up and down.
The utility model is further arranged to: the quantity of the idler wheel is two and distribution up and down.
By using above-mentioned technical proposal, since the quantity of idler wheel is two and distribution up and down, when effectively increasing sliding
Stability.
The utility model is further arranged to: the position-limited rack is in hollow setting.
It is reduced while guaranteeing its support effect by using above-mentioned technical proposal since position-limited rack is in hollow setting
Corresponding material loss.
The utility model is further arranged to: four oil cylinder synchronous lifting mechanisms further include the sensing being set to above platform
Device and the brake platform rack for moving up highest distance on outer framework for limiting platform is set.
By using above-mentioned technical proposal, platform can effectively be limited to moving up by sensor, the setting for braking rack
Dynamic highest distance.
The utility model is further arranged to: further including for positioning limit frame in the bolt of outer framework bottom surface.
It, can be by position-limited rack effective position in outer frame bottom surface by the setting of bolt by using above-mentioned technical proposal
On.
The utility model is further arranged to: the outer framework bottom surface is just connected with thereon for positioning limit frame
Reinforcement block.
By using above-mentioned technical proposal, the effect to outer framework support can effectively improve by the setting of reinforcement block.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It is a kind of four oil cylinders synchronous lifting mechanism disclosed by the utility model, including outer framework 1, installation referring to figs. 1 to 2
Oil cylinder 4 above 1 bottom surface of outer framework, the platform 5 above oil cylinder 4 and above platform 5 with for controlling oil cylinder
About the 4 flexible synchronous valves to realize platform 5 lifting and decline.
Four oil cylinder synchronous lifting mechanisms further include the limit for being symmetrically disposed on 1 top of outer framework and 5 two sides of platform that are placed in
Frame 10 and the limitting casing 11 above position-limited rack 10 are provided in the limitting casing 11 during moving up and down for platform 5
The idler wheel 2 of balance is kept, the quantity of the idler wheel 2 is two and distribution up and down, and the position-limited rack 10 is in hollow setting.
Four oil cylinder synchronous lifting mechanisms further include being set to the sensor 3 of 5 top of platform and being arranged on outer framework 1
To move up the brake platform rack 7 of highest distance for limiting platform 5.
Be to improve to the support effect of outer framework 1, four oil cylinder synchronous lifting mechanisms further include for positioning limit frame 10 in
The bolt 8 of 1 bottom surface of outer framework, 1 bottom surface of outer framework are just connected with the reinforcement block 9 for positioning limit frame 10 thereon.
The implementation principle of the present embodiment are as follows: four oil cylinder synchronous lifting mechanisms, platform 5 are limited with idler wheel 2, and oil cylinder 4 is mounted on
1 bottom surface of outer framework passes through the flexible lifting and decline to realize platform 5 of oil cylinder 4.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
