Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 to Figure 3, a kind of small-sized without supporting leg aerial platform, comprise car chassis 1, subframe 2, rotary table 3, jib, arm support oil cylinder, job platform 9 and levelling gear 8, described car chassis adopts microcaloire chassis; Jib comprises upper arm 7 and underarm 4, one end of underarm 4 is hinged on rotary table 3, the other end and upper arm 7 hinged, the other end and the job platform 9 of upper arm 7 are hinged, arm support oil cylinder comprises upper arm oil cylinder 6 and underarm oil cylinder 5, and underarm oil cylinder 5 one end is hinged at the upper end of rotary table 3, and the other end is hinged at the lower end of underarm 4, upper arm oil cylinder 6 one end is hinged at the upper end of upper arm, and the other end is hinged at the lower end of underarm; The both sides of subframe 2 are provided with lateral stability torsion bar 10, lateral stability torsion bar 10 comprises torsion bar 10-1, two permanent seat 10-2, two connecting rod mechanism 10-3 and two Connection Block 10-4, torsion bar 10-1 is fixed on permanent seat 10-2, two permanent seat 10-2 are arranged on the both sides of subframe 2 respectively, connecting rod mechanism 10-3 one end and torsion bar 10-1 hinged, the other end and Connection Block 10-4 hinged, Connection Block 10-4 is arranged on the both sides of car chassis 1.

In order to meet the demand of narrow regional high climber's condition, employ the microcaloire car chassis that overall dimensions of a car is little, crossing ability is good, in order to expendable weight, meet four tires on microcaloire chassis as support, aloft work can be carried out by direct lift arm as long as operationally come to a complete stop after car, substantially increase work efficiency, cause in order to avoid tire is excessively soft that car load side tilt angle is large affects aloft work work safety, be provided with and keep the laterally stable torsion bar structure of car load, when the tire of operation side produces the trend moved down, the side that center of gravity can be partial to vehicle causes the spring plate of both sides, microcaloire chassis to be out of shape, the torsion bar end be connected with connecting rod of homonymy upwards moves relative to vehicle frame, and the torsion bar end of opposite side relative to vehicle frame to moving down, torsion bar both sides deflecting direction is different, torsion bar has by the trend reversed, and the elasticity of torsion bar itself recovers the distortion generation resistance of twist moment to torsion bar itself, thus reduce the lateral inclination of vehicle body, reduce the danger of vehicle rollover, improve the security and stability of operation, the connecting rod mechanism be connected with torsion bar can freely swing, and prevents torsion bar rigidity from fractureing, torsional moment is played to the effect of buffering.

Levelling gear 8 comprises pipe link one 8-1 and pipe link two 8-2, and one end and the job platform 9 of pipe link one are hinged, the other end and underarm 4 hinged, one end and the upper arm 7 of pipe link two are hinged, the other end and rotary table 3 hinged; The hinge of the hinge of the hinge of the hinge of upper arm 7 and job platform 9, pipe link one 8-1 and job platform 9, pipe link one 8-1 and upper arm 7, upper arm 7 and underarm 4 forms a parallelogram; The hinge of the hinge of the hinge of the hinge of underarm 4 and rotary table 3, pipe link two 8-2 and rotary table 3, pipe link two 8-2 and underarm, underarm 4 and upper arm 7 forms second parallelogram.

Due to the hinge of the hinge of upper arm and job platform, pipe link one and job platform, the angle that line between the two and horizon keep is constant, the angle kept by the known pipe link of parallel-crank mechanism motion characteristics one and the hinge of upper arm, the line between upper arm and the hinge of underarm and horizon is constant, another parallelogram principle is identical, thus know workplatform in motion process by inference and remain level relative to horizon, ensure that the safety of operating personal.

The utility model employs light-duty, that crossing ability is strong microcaloire car chassis, has luffing operation function, can meet and not easily pass through narrow the demand that aloft work is carried out in area; Use Tire support ground during operation, ensure that vehicle body does not tilt by car load torsion bar device, improve the safety and stability of car load; Utilize the parallelogram levelling gear of employing, structure is simple simultaneously, utilize the principle of parallelogram make job platform all the time with ground keeping parallelism, be better safety control that operating personnel provides.
