Abstract
The invention discloses a maintenance protective device for a scissor type aerial work platform, which comprises a base, wherein a scissor lifting assembly is arranged on the base, and comprises a scissor device and hydrocylinders, the scissor device comprises multiple layers of scissor units, the multiple layers of scissor units are hinged to each other through scissor shafts, a maintenance support frame is movably connected onto scissor shaft of each layer, one ends of the maintenance support frames are connected with the scissor shafts and can rotate around the scissor shafts, and the other ends of the maintenance support frames are Y-shaped and used for supporting the scissor shafts of the adjacent layers. According to the maintenance protective device, when the aerial work platform is maintained, the scissor units are lifted layer by layer through the hydrocylinders of the scissor lifting assembly, and then the maintenance support frames of the scissor shafts are rotated to enable the Y-shaped ends of the maintenance support frames to be propped against the scissor shafts of the adjacent layers, so that the multiple layers of scissor units all are supported by the maintenance support frames from bottom to top, and if the platform goes wrong during maintenance, the protective device can protect the maintenance personnel.
Description
?
Technical field
The present invention relates to a kind of high-altitude operation platform.
Background technology
High-altitude operation platform is the product of serving the mobility aloft work such as every profession and trade aloft work, equipment safety check, maintenance.Need the staff to stand on superincumbent platform in the time of by aerial working platform operation, thus need platform that enough safetys are arranged, otherwise the danger that the staff just may drop.Safety for the upkeep operation platform, need often job platform to be overhauled, High Altitude Platform need to be gone up in maintenance, service personnel overhauls below platform, if the oil cylinder generation leakage of oil of support platform or other fault, platform falls downwards, and following maintainer will cause danger.
Summary of the invention:
The object of the invention is to for above-mentioned situation, a kind of maintenance protective device of cutting the fork high-altitude operation platform is provided, can go up at platform and it firmly be supported when keeping in repair, prevent that platform from falling.
A kind of maintenance protective device of cutting the fork high-altitude operation platform, comprise base, be provided with on base to cut to fork and rise assembly, cut to fork and rise assembly and include and cut fork device and hydraulic ram, cut fork device and comprise that multilayer cuts the fork unit, each layer cut between the fork unit and is hinged by cutting fork shaft, cut for every layer and be connected with the maintenance support frame on fork shaft, maintenance support frame one end with cut fork shaft and be connected, and can rotate around cutting fork shaft, the maintenance support frame other end is the fork shaft of cutting that the Y type is used for supporting adjacent layer.
High-altitude operation platform of the present invention is in maintenance; fork the hydraulic ram that rises assembly and will cut fork the going up of Floor 1, Unit layer by cutting; then rotate the maintenance support frame of cutting fork shaft; its end that is the Y type is withstood cutting on fork shaft of adjacent layer; whole so from top to bottom every layer cut the fork unit have the maintenance support frame to support; if platform et out of order in maintenance process can play the protection to the maintainer.
Description of drawings:
Fig. 1 is the structural representation one of job platform of the present invention.
Fig. 2 is the structural representation two of job platform of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
As shown in Fig. 1-2, a kind of maintenance protective device of cutting the fork high-altitude operation platform, comprise base 1, be provided with on base 1 to cut to fork and rise assembly, cut to fork and rise assembly and include and cut fork device 2 and hydraulic ram 3, cut fork device 2 and comprise that multilayer cuts the fork unit, each layer cut to pitch between the unit and is hinged by cutting fork shaft 4, cut for every layer and be connected with maintenance support frame 5 on fork shaft 4, maintenance support frame 5 one ends with cut fork shaft 4 and be connected, and can rotate around cutting fork shaft 4, maintenance support frame 5 other ends are the fork shaft of cutting that the Y type is used for supporting adjacent layer.
High-altitude operation platform is in maintenance; fork the hydraulic ram that rises assembly and will cut fork the going up of Floor 1, Unit layer by cutting; then rotate the maintenance support frame of cutting fork shaft; its end that is the Y type is withstood cutting on fork shaft of adjacent layer; whole so from top to bottom every layer cut the fork unit have the maintenance support frame to support; if platform et out of order in maintenance process can play the protection to the maintainer.
