Description
Technical field
The present invention relates to the lifting device of multiaxle trucks brake function test, specifically a kind of unpowered locking summit
Rocking arm lifting device.
Background technology
With developing rapidly for the modernization of national defense and national economy, the special vehicle of some high-power, big bearing capacitys obtains
To being widely applied.It is simple by the bearing capacity for increasing single axle, drop due to being limited by pavement conditions, traffic law
Low complete vehicle quality oneself through not reaching requirement, the requirement of national standard can only be met by increasing the quantity of axletree.Therefore multiaxis
The usage safety performance of vehicle is taken seriously further.
According to the GB21861 of newest revision《Vehicle Security examines project and method》In, standard revision protrudes weight
Point vehicle, enhance school bus, large and medium bus, weight medium truck, the safe practice examination requirements of trailer.For multiaxis lorry,
By and fill the truck combination that axle semitrailer forms and to carry out loading brake inspection, it is then anti-using the roller with stage body lifting function
Power formula brake test bench, now in the domestic market, the application also without such check-out console.
The patent No.：95223459.9 patent discloses a kind of repair lifting platform for vehicle, by pedestal, support stage body and lifting
Mechanism is formed, and support stage body is hinged on pedestal with rotating shaft, forms seesaw structure；Elevating mechanism is in the side of rotating shaft, upper end
It is hinged with support stage body, lower end is hinged with pedestal.
The patent No.：201420267341.0 patent discloses a kind of motor vehicle repair hydraulic lifting platform, including two sets of acts
Frame is risen, lifting frame has the left and right sides to be formed with the chassis of lower raceway, it is characterized in that two groups are connected with chassis has in the centre of X-shaped

Connecing, the left and right sides under table top is formed with raceway, and hydraulic cylinder is connected between support arm and chassis, and by the piston of hydraulic cylinder
The opening angle of two groups of interconnection support arms of bar extension and contraction control so that the parallel rise of table top or decentralization, in two sets of lifting frames
Hydraulic cylinder be connected respectively by two hydraulic oil pipes with same pedal hydraulic jack, realize lifting automobile or so simultaneously
The trailing wheel or front-wheel of both sides.
Both above-described lift racks can not be all realized in the lifting unpowered locking of peak, and take up an area face
Product is big, and the arrangement for being unfavorable for testing stand is laid, it is impossible to the use for coordinating anti-force type drum braking to test, can not realize multiaxle trucks
Load the test of braking ability.
Therefore, develop it is simple and reasonable, for axle lorry, by and fill the truck combination that axle semitrailer forms and load
Brake test bench, specification multiaxle trucks loading braking ability is come with this, it is ensured that it has more preferable safety and reliability, has been one
The extremely urgent task of item.
