Description
Technical Field
The invention belongs to the technical field of aerial work platforms, and particularly relates to an anti-blocking structure of a stretching platform for an aerial work platform.
Background
At present, aerial work platforms are widely used in the aspects of aerial work, equipment installation, maintenance and the like of various industries. The scissor-fork type aerial work platform is used as one of the main product categories, and the scissor-fork type mechanical structure of the scissor-fork type aerial work platform enables the lifting platform to have higher stability after being lifted; the high-altitude work platform has a wide work platform and high bearing capacity, and the high-altitude work range is wider.
the scissors formula aerial working equipment's main platform generally can leave certain clearance (satisfying standard requirement, nevertheless also guaranteeing the slip demand) with stretching out between the platform, just so can guarantee stretching out that the platform can be convenient roll-off, withdraw on main platform. However, the size of the gap is not specified, so that when the gap is too small, the gap between the two gradually disappears through repeated compaction under load and deformation of the bottom plate of the extending platform, and finally the extending platform is clamped.
Disclosure of Invention
The invention provides an anti-blocking structure of an extending platform for an aerial work platform, aiming at the technical problems in the prior art, and the anti-blocking structure can solve the problems that the gap between the extending platform and a main platform of scissors type aerial work equipment is too small, the extending platform and the main platform are blocked and lose the function due to deformation.
The technical scheme adopted by the invention is as follows: the utility model provides an anti-sticking of platform constructs for high altitude construction platform stretches out, includes main platform and stretches out the platform, it is located to stretch out the platform main platform, it is provided with strengthening rib and cushion to stretch out the platform back, be equipped with on the main platform and be used for bearing the cushion slide metal plate of cushion. The cushion block is made of hard plastic, and the reinforcing rib and the cushion block slideway metal plate are made of metal. After the extension platform is installed with the main platform in a matching way, the cushion block is in metal plate contact with the cushion block slideway at the moment and can slide on the cushion block slideway. Because the bottom metal plates of the extending platform are all about 3mm steel metal plates, the bottom metal plates deform after the load of about 200KG is added, and the extending platform can be prevented from directly contacting with the bottom metal plates of the main platform even if the bottom metal plates deform due to the action of the platform cushion blocks; the platform cushion block can always smoothly slide on the cushion block slideway plate, thereby ensuring stable and effective extending and retracting movement between the two platforms. The reinforcing ribs extending out of the bottom metal plate of the platform play a role in reinforcing the bottom metal plate and reducing the deformation amount of the bottom metal plate.
Preferably, lateral cushion blocks are arranged on the outer lateral surfaces of the two sides of the extending platform. The lateral cushion blocks are made of hard plastics, and the lateral cushion blocks rub the inner side face of the main platform and are not deformed, so that the left position and the right position of the extension platform in the main platform are guaranteed.
Preferably, a lower pulley slideway is arranged on the inner side face of the main platform, a lower pulley matched with the lower pulley is arranged at the rear part of the outer side face of the extending platform, a platform limiting plate is arranged at the front part of the outer side face of the extending platform, an upper pulley is arranged on the platform limiting plate, and the lateral cushion blocks are respectively positioned on the lower pulley and the platform limiting plate. The extension platform is provided with a pedal limit switch, and the main platform is provided with a limit bracket matched with the main platform. The pulley is arranged on the extension platform, so that the extension platform can conveniently slide out and retract on the main platform, and the possibility of jamming of the extension platform is reduced.
Compared with the prior art, the invention has the beneficial effects that: the pulley is arranged at the joint of the extension platform and the main platform, so that the extension platform can slide conveniently, and the possibility of blocking is reduced. The bottom surface and the side surface of the extending platform are both provided with cushion blocks, and the main platform is provided with a cushion block slideway plate which separates the main platform from the extending platform to prevent the main platform from being blocked due to the deformation of the extending platform. The reinforcing ribs enable the bottom metal plate extending out of the platform to be stressed uniformly, and deformation amount is reduced. The invention has low cost and obvious function, and can solve the problem of dead locking of the extending platform.
