Abstract
The invention discloses a hydraulic support device used for a drop-and-pull transport semitrailer. The hydraulic support device comprises a hydraulic oil cylinder and a supporting foot, rear connecting plates are arranged on the side face of the hydraulic oil cylinder, the hydraulic oil cylinder is a double-acting hydraulic oil cylinder, a piston rod of the hydraulic oil cylinder is of a solid structure, the rear connecting plates are thickened steel plates, arc grooves are formed in the rear connecting plates for being matched with the hydraulic oil cylinder, and a telescopic part of the hydraulic oil cylinder is sleeved with a durable telescopic rubber pipe. According to the device, the hydraulic power is utilized, the ascending and descending speed is fast, the power is large, and the welding strength between the connecting plates and the oil cylinder is guaranteed.
Description
Technical field
The present invention relates to Drop and pull transport superimposed trailer and support field, specifically belong to a kind of hydraulic supporting device for Drop and pull transport superimposed trailer.
Background technology
Drop and pull transport car has following advantage: one is reduce handling wait time, accelerates tractor truck turnover, improves conveying efficiency and labor efficiency; Two is reduce vehicle sky to sail and ineffective traffic, reduces energy consumption and exhaust emission; Three is save Storage of Goods facility, facilitates the owner of cargo, reduces logistics cost; Four is be convenient to organize the multimetering transports such as the bow-backed transport of water route ro-ro transport, railway, promotes the development of multi-transportation.
Tractor truck and superimposed trailer be thrown off, a requisite link is exactly shake the bearing set of superimposed trailer, is raised by superimposed trailer pulling face, departs from tractor truck, tractor truck could be driven away.But traditional supporter of semi-trailer is all the lifting mechanism of machinery, realize by feed screw nut and simple speed-changing mechanism.Although its hoisting capacity has 28-30T, when superimposed trailer is fully loaded with cargo, be just difficult to shake, bearing set and enable the shaking of import also need to expend long time, generally all want 30 minutes at all.Lose time, and shake gruelling, therefore, in the middle of Drop and pull transport, shake the bottleneck that bearing set has become transit link.
Summary of the invention
The object of this invention is to provide a kind of hydraulic supporting device for Drop and pull transport superimposed trailer, by hydraulic power, rising or falling speed is fast, and power is large, ensures the weld strength of connecting panel and oil cylinder.
Technical scheme of the present invention is as follows:
A kind of hydraulic supporting device for Drop and pull transport superimposed trailer, include hydraulic ram, leg, hydraulic ram side is with rear connecting panel, hydraulic ram is double-act-ing hydraulic J-Horner, the piston rod of hydraulic ram is solid construction, rear connecting panel for adding plate iron, and has circular arc notch by rear connecting panel and coordinates with hydraulic ram, is set with durable extension rubber sebific duct outside hydraulic ram telescopic section.
Described hydraulic ram side is provided with installation bidirectional hydraulic lock.
Between described rear connecting panel and hydraulic ram, junction is provided with brace panel.
Advantageous Effects of the present invention is as follows:
1, bearing set base portion uses double-act-ing hydraulic J-Horner, replaces the screw-nut structure of traditional mechanical supporting device, and by hydraulic power, rising or falling speed is fast, and power is large;
2, the piston rod of hydraulic ram uses solid construction, and what prevent superimposed trailer from mounting is that bearing set and ground friction damage piston rod;
3, after bearing set, connecting panel uses the steel plate thickeied to be coordinated with hydraulic ram by Machining Arc notch, and both sides increase brace panel, ensure the weld strength of connecting panel and oil cylinder;
4, bearing set and superimposed trailer to be connected to traditional mechanical supporting device general, also similar to mechanical supporting device in profile, be more easily easily accepted by a user;
5, cylinder piston rod telescopic section uses durable telescopic rubber protection of pipe, the damage of preventing pollution and piston rod;
6, bidirectional hydraulic lock installed by bearing set, prevents pressure release and booster.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of hydraulic supporting device for Drop and pull transport superimposed trailer, include hydraulic ram 1, leg 2, hydraulic ram 1 side is with rear connecting panel 3, hydraulic ram 1 is double-act-ing hydraulic J-Horner, and the piston rod of hydraulic ram 1 is solid construction, and rear connecting panel 3 is for adding plate iron, and have circular arc notch by rear connecting panel 3 and coordinate with hydraulic ram 1, be set with durable extension rubber sebific duct outside hydraulic ram 1 telescopic section.Hydraulic ram 1 side is provided with installs bidirectional hydraulic lock 4.Between rear connecting panel and hydraulic ram, junction is provided with diagonal brace connecting panel 5.
