Description
Technical field
The utility model is related to machinery field, more particularly to a kind of luffing device with mobile counterweight and working at height are flat
Platform.
Background technology
High-altitude operation vehicle is that transport staff and the equipment using equipment to high-altitude contraposition in high-altitude are installed, tieed up
Shield, the special vehicle cleaned, the good, operation with transaction capabilities compared with traditional operating type such as scaffolding, ladder
The advantages that efficient, job safety, it is now widely used for the infrastructure industry such as electric power, traffic, petrochemical industry, communication, gardens.
Domestic high-altitude operation vehicle is mainly formed supporting leg by vehicle body dead weight in terms of operation stability anti-at present
Torque carrys out the torque of balanced operation platform generation to realize the stabilization of its operation, but with big height, large span equipment in industry
Facility is continuously increased, it is desirable that the operation height and amplitude of high-altitude operation vehicle are also continuously increased, and in turn result in high-altitude operation vehicle
Supporting leg span is also increasing, but larger supporting leg span not only needs to occupy larger Active workings space, but also larger
Supporting leg span is also easy to cause frame distortion and then influences operational security.
The span of horizontal support legs is usually carried out classification pipe by existing high-altitude operation vehicle in order to adapt to different operating environments
Reason is generally divided into the full stretching of horizontal support legs, partly stretches out and do not stretch out three kinds of working conditions, and three kinds of working conditions, which correspond to, generates three
The different transaction capabilities curve of kind, operating environment that this often sacrifices operation height and operation amplitude is adapted to, with 18 meters
For high-altitude operation vehicle, maximum operation amplitude is 12 meters under the fully extended state of horizontal support legs, maximum operation height is 18 meters,
Operation height is 12.5 meters when operation amplitude is 9 meters, and when operation amplitude is 6 meters, operation height is 16 meters；Horizontal support legs are partly stretched
Maximum operation amplitude under doing well is 9 meters, and operation height at this time is only 6 meters；Maximum under horizontal support legs not stretching state
6 meters of operation amplitude, operation height at this time also only has 6 meters, and can only work in rear area, when high-altitude operation vehicle is needed narrow
When the narrow place in narrow road face or space carries out working at height, often horizontal support legs half stretch out and not stretching situation under it is corresponding
Operation height and amplitude cannot meet requirement, can only complete working at height by step ladder or miscellaneous equipment, this is serious
High-altitude working safety operating instruction is violated, operation is absolutely unsafe, and has very high security risk, personal wound is will appear when serious
Die accident.
To solve the above-mentioned problems, patent publication No. CN106629523A discloses a kind of high-altitude with self-stabilization system
