Utility model content
Technical problem to be solved in the utility model is to provide a kind of high pedestal jib crane and rotates drop-gear box maintenance platform, and this maintenance platform can prevent rotating drop-gear box topples over, and handled easily personnel carry out maintenance activity, and keep on-the-spot order, improve maintenance efficiency.
The technical scheme solved the problems of the technologies described above is:
A kind of high pedestal jib crane rotates drop-gear box maintenance platform, it comprises platform, movable ladder, fixing device, there is gap the table top side of platform, the width of gap matches with the width rotating drop-gear box, fixing device is by swing arm, leading screw, clamping head, handle forms, the two ends of swing arm lay respectively at the gap both sides of platform, one end of swing arm is arranged on the lower surface of the flat surface of gap side by rotating shaft, the other end of swing arm is connected by the lower surface of pin with the flat surface of gap opposite side, the distance of swing arm and gap end is greater than the opposite side width rotating drop-gear box, the central central axis along gap of swing arm has the screw of level, leading screw is through the screw of swing arm, clamping head and handle are connected to the two ends of leading screw, the width of the width of movable ladder and the gap of platform matches.
Above-mentioned high pedestal jib crane rotates drop-gear box maintenance platform, and described platform is provided with railing, has casing under platform, casing has the side door that can open.
Above-mentioned high pedestal jib crane rotates drop-gear box maintenance platform, and the bottom of described movable ladder is casing, and castor is arranged at the bottom of casing, and anterior castor is directional wheel, and rear castor is with brake gear.
The beneficial effects of the utility model are:
Platform of the present utility model has gap can put into rotation drop-gear box, rotation drop-gear box can clamp by the clamping head that swing arm fixes rear leading screw front end by pin, and maintainer climbs up platform by movable ladder and decomposes rotation drop-gear box, keep in repair and assemble.The utility model effectively can be fixed and rotate drop-gear box, avoids rotating drop-gear box and topples in maintenance process, prevent safety misadventure, increase operational security; Maintainer stands on platform and carries out maintenance activity, convenient, laborsaving, substantially increases maintenance efficiency; The accessory rotated after drop-gear box decomposition puts into mesa base by side door, to keep on-the-spot clean and tidy, avoids damage of components.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the view that the swing arm of Fig. 1 is opened;
Fig. 3 is working state schematic representation of the present utility model.
In figure, mark is as follows: platform 1, railing 2, casing 3, side door 4, gap 5, swing arm 6, leading screw 7, rotating shaft 8, clamping head 9, handle 10, movable ladder 11, anterior castor 12, rear castor 13, rotation drop-gear box 14.
Detailed description of the invention
The utility model is made up of platform 1, movable ladder 10 and fixing device.
Show in Fig. 1, there is gap 5 the table top side of platform 1, and the width of gap 5 matches with the width rotating drop-gear box 14, rotates drop-gear box 14 and can put in gap 5, carry out maintenance activity on the platform 1 by maintainer.
Show in Fig. 1, platform 1 is provided with railing 2, platform has casing 31 time, and casing 3 has the side door 4 that can open.In maintenance process, the accessory rotated after drop-gear box 14 decomposition puts into casing 3 bottom platform 1 by side door 4, to keep on-the-spot clean and tidy, avoids damage of components.
Fig. 1 shows, and fixing device is made up of swing arm 6, leading screw 7, clamping head 9, handle 10.The two ends of swing arm 6 lay respectively at gap 5 both sides of platform 1, one end of swing arm 6 is arranged on the lower surface of the flat surface of gap 5 side by rotating shaft 8, the other end of swing arm 6 is connected by the lower surface of pin with the flat surface of gap 5 opposite side, swing arm 6 is greater than with the distance of gap 5 end the opposite side width rotating drop-gear box 14, rotation drop-gear box 14 can be put between swing arm 6 and gap 5 end, then clamp.
