Description
Technical field
The utility model belongs to high-altitude operation platform production field, specifically a kind of self-propelled aloft working platform anti-tipping apparatus.
Background technology
In aloft work process, staff on self-propelled scissor high-altitude operation platform can move forward into line operate simultaneously to the lifting mechanism of job platform and bearing chassis, carry out continuous working, avoid the replacing because of work place cause the frequent lower work platform of staff and lose time.
But in real work, when job platform raised configuration, the overall center of gravity of job platform is moved, if job platform is when advancing in gradient road surface that is comparatively large or that jolt, if road speed is too fast or certain wheel is fallen in pit, job platform can be caused to tilt, the staff still on workplatform is in the middle of danger.For this reason, need design a kind of job platform speed of travel and automatically change and anti-tipping mechanism, this case produces thus.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, the self-propelled aloft working platform anti-tipping apparatus of safety and stability.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of self-propelled aloft working platform anti-tipping apparatus, comprise the pressure block be slidably connected in frame, described pressure block can slide up and down, and is provided with depression bar above described pressure block;
Be provided with two relative quadrants below described pressure block, described quadrant is connected with gantry rotation by fixed pin shaft, and described quadrant is contacted with pressure block by the hook-shaped portion of its one end;
The described quadrant other end has drive link by hinge, the described drive link other end has stay bearing plate by hinge, described stay bearing plate by fixed pin shaft and frame hinged, have elastic force cylinder by hinge in the middle part of described drive link, described elastic force cylinder by fixed pin shaft and frame hinged.
Further, be provided with corresponding travel switch below described quadrant, described travel switch is fixed in frame.
The beneficial effects of the utility model: the utility model is by installing stay bearing plate on job platform both sides; by the mating reaction of pressure block, quadrant, drive link and elastic force cylinder; when implementation platform rises, stay bearing plate overturns downwards automatically; be in guard mode, ensure that job platform inclination maximum is no more than 2.5 degree, ensure that walking is stablized and avoids toppling over; greatly increase the safety of job platform; structure is simple, easy for installation, safety and stability.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model provides a kind of self-propelled aloft working platform anti-tipping apparatus, comprise the slide rail 2 that two of being arranged in frame 1 are relative, slide rail 2 is provided with the pressure block 3 by chute and slide rail sliding block joint, and pressure block 3 can slide up and down along slide rail 2.Be provided with the depression bar 4 be connected with job platform scissor arm above pressure block 3, when scissor arm draws in, drive depression bar 4 crimping pressure block 3 downwards, when scissor arm rises, drive depression bar 4 upwards away from pressure block 3.
Be provided with two relative quadrants 5 below pressure block 3, quadrant 5 is rotationally connected by fixed pin shaft and frame 1.Quadrant 5 is contacted with pressure block 3 by the hook-shaped portion of its one end, when scissor arm draws in, pressure block 3 under depression bar 4 suppressing action along slide rail 2 slide downward, quadrant 5 is driven upwards to rotate, when scissor arm rises, depression bar 4 is away from pressure block 3, and quadrant 5 is under self gravitation effect, fixed pin shaft in frame 1 rotates, and pressure block 3 is moved up along slide rail 2.
Quadrant 5 other end has Z-shaped drive link 6 by hinge, and drive link 6 other end has stay bearing plate 8 by hinge, and stay bearing plate 8 is arranged in frame 1 by fixed pin shaft, hinged with frame 1; Have elastic force cylinder 9 by hinge in the middle part of drive link 6, elastic force cylinder 9 by fixed pin shaft and frame 1 hinged, elastic force cylinder 9 piston rod by elastic force effect removable, its maximum amount of movement is determined by elastic force cylinder 9 stroke.
When quadrant 5 rotates, the drive of drive link 6 at quadrant 5 and the effect lower swing of elastic force cylinder 9, the fixed pin shaft of stay bearing plate 8 in frame 1 is driven outwards to rotate 90 degree, the ground Clearance of stay bearing plate 8 is diminished, if job platform wheel is strayed in hole, stay bearing plate 8 just can kiss the earth, supports job platform, avoids toppling over generation.
When quadrant 5 upwards rotates, the drive of drive link 6 at quadrant 5 and the effect lower swing of elastic force cylinder 9, drive the fixed pin shaft of stay bearing plate 8 in frame 1 inwardly to rotate 90 degree, the ground Clearance of the platform that resumes operation.
Two corresponding travel switches 7 are also provided with below two quadrants 5, travel switch 7 is fixed in frame 1, for controlling the rotating speed of job platform drive motor, after quadrant 5 rotates certain angle, quadrant 5 depression stroke switch 7, travel switch 7 sends electric signal, and reduce the rotating speed of drive motor, job platform realizes low-speed running; When quadrant 5 upwards rotates, quadrant 5 departs from travel switch 7, and travel switch 7 sends electric signal, and improve the rotating speed of drive motor, the platform that resumes operation is walked fast.
The utility model is by installing stay bearing plate on job platform both sides; by the mating reaction of pressure block, quadrant, drive link and elastic force cylinder; when implementation platform rises, stay bearing plate overturns downwards automatically; be in guard mode, ensure that job platform inclination maximum is no more than 2.5 degree, ensure that walking is stablized and avoids toppling over; greatly increase the safety of job platform; structure is simple, easy for installation, safety and stability.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
