Description
Technical field
Automatic turning device for hydraulic control wire rope leg of the present invention is specifically related to a kind of mechanism of automatic upset of large-tonnage lorry-mounted crane support oil cylinder
Background technology
The large-tonnage lorry-mounted crane is one of product most popular on the truck with loading crane market, but the volume of large-tonnage lorry-mounted crane (6.3 tons or more than the 160KNm) and deadweight are bigger than normal.When carrying out the transport trolley chassis refit, if be arranged between operator's compartment and the railway carriage, the automotive frame both sides respectively are equipped with fuel tank and accumulator jar, and at this moment the car load width will exceed the limit value that national standard requires; If be arranged in the railway carriage afterbody, the departure angle of car load reduces, and influences the crossing ability of car load.Present most of producer adopts these two kinds of methods to solve: 1. the installation site that changes car load fuel tank and accumulator jar; But changed the connection of automobile original pipeline, electric wiring, had potential safety hazard.2. adopt the support oil cylinder mode of manually overturning; But the support oil cylinder deadweight is bigger than normal, and labour intensity is too big; The height of car chassis is higher simultaneously, adopts manual upset mode to be difficult for the continuous upset that realizes that vertical 180 ° of scopes are interior, can only realize 45 ° or 60 ° of continuous upsets that scope is interior.
Summary of the invention
Problem to be solved by this invention is the deficiency at prior art, and it is power that the overturning oil cylinder with lorry-mounted crane is provided, and has realized the device that automatically continuously overturn of support oil cylinder in vertical 180 ° of scopes.
For solving the problems of the technologies described above, the technical solution used in the present invention is: automatic turning device for hydraulic control wire rope leg, comprise: support oil cylinder, overturning oil cylinder, steel rope, idle pulley, fixed pulley axis, supporting rack, pull beam and wedge-shaped sleeve, pull beam and outwards be hinged with supporting rack by fixed pulley axis, the upper end upside-down mounting of supporting rack has support oil cylinder and overturning oil cylinder, the middle part of supporting rack is provided with idle pulley, the midway location that pulls beam is provided with wedge-shaped sleeve, wedge-shaped sleeve is positioned at the lower right of fixed pulley axis, one end of steel rope is fixed on the wedge-shaped sleeve, the other end of steel rope is fixed on the flexible end of overturning oil cylinder, and the centre portion of steel rope is wrapped on idle pulley and the fixed pulley axis.
Automatic turning device for hydraulic control wire rope leg of the present invention compared with prior art has following beneficial effect:
The present invention utilizes turning device and the shared pressure oil circuit of support oil cylinder, has both realized the upset continuously automatically of support oil cylinder, has satisfied the flexible of support oil cylinder again simultaneously.The present invention pulls beam by the connection of steel rope one end, pull beam and be positioned at the two sides of tail of lorry-mounted crane, be in stationary state, walk around the fixed pulley axis and the wheel of falling in the middle of the steel rope, the other end of steel rope links to each other with the flexible end of overturning oil cylinder, and overturning oil cylinder is fixed on the supporting rack with support oil cylinder, supporting rack is hinged on by fixed pulley axis and pulls on the beam, by the flexible of overturning oil cylinder supporting rack is rotated around fixed pulley axis like this, its anglec of rotation can be according to the length of the expansion link of overturning oil cylinder, position between each part is determined, can rotate 0-180 ° of optional position; Whole automatic turning device is simple and compact for structure, and cost is low, dependable performance, and good looking appearance can carry out modular adaptation or choosing dress.On lorry-mounted crane, use, realized the complete machine automation of operation.
