Description
Technical field
The utility model relates to a kind of lifting assembly of cranking arm of crank arm type self-walking aerial working platform, belongs to aloft work field.
Background technology
High-altitude operation platform (Aerial work platform) is the product of serving the mobility aloft work such as every profession and trade aloft work, equipment installation, maintenance.First of the lifting assembly of cranking arm of existing high-altitude operation platform is cranked arm and second is realized lifting by oil cylinder is set between cranking arm, if whole platform uses oil cylinder too much, can make platform unstable, safety performance variation.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and the lifting assembly of cranking arm of the crank arm type self-walking aerial working platform that a kind of lifting is stable, safety performance is good is provided.
The utility model solves the technical scheme that its technical matters adopts: a kind of lifting assembly of cranking arm of crank arm type self-walking aerial working platform, comprise fixed arm, first cranks arm, second cranks arm, the 3rd cranks arm, the first oil cylinder, the second oil cylinder and pull bar, the one end of cranking arm, described fixed arm one end and first is hinged, first other end and second one end of cranking arm of cranking arm is hinged, second other end and the 3rd one end of cranking arm of cranking arm is hinged, described the first oil cylinder is arranged between fixed arm and first cranks arm, one end and the fixed arm of this first oil cylinder are connected, its other end and first is cranked arm and is connected, described the second oil cylinder be arranged at second crank arm and the 3rd crank arm between, crank arm and be connected in one end of this second oil cylinder and second, its other end and the 3rd is cranked arm and is connected, described the second oil cylinder and the first oil cylinder lay respectively at crank arm assembly both sides, described pull bar is arranged between fixed arm and second cranks arm, and this pull bar is positioned at the first oil cylinder homonymy, this pull bar one end and fixed arm are connected, its other end that crank arm is connected with first one end being connected of cranking arm with second.
Described pull bar and first is cranked arm and is be arranged in parallel, and described pull bar, fixed arm, first are cranked arm and the second formation parallelogram of cranking arm.
The oil cylinder seat end of described the first oil cylinder and the other end of fixed arm are connected, and its rod end is connected with first one end being connected with fixed arm that crank arm.
The oil cylinder seat end of described the second oil cylinder that crank arm is connected with first one end being connected of cranking arm with second, and its rod end that crank arm is connected with second one end being connected of cranking arm with the 3rd.
The beneficial effects of the utility model: this high-altitude operation platform arranges pull bar between fixed arm and second is cranked arm, in the time that the first oil cylinder stretches, first cranks arm upwards rotates, second cranks arm also upwards rotates under the pulling force of pull bar, realized the second rising of cranking arm, this platform has replaced oil cylinder with pull bar, has reduced the usage quantity of oil cylinder, make the to crank arm more stable lifting of lifting assembly, safety performance is better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
