Summary of the invention
Technical matters to be solved by this invention is: a kind of simple in structure, easy to operate, safe service platform of opening and installing in manhole cover is provided.
Solve this technical problem, technical scheme of the present invention is: a kind of service platform for manhole cover unlatching and installation, comprise manhole cover, hold-down arm, L type otic placode, bolt, supporting plate, bearing pin, set pin, manhole cover is connected on the set manhole of bulkhead by bolt, it is characterized in that: an end of described hold-down arm is provided with pin shaft hole and fixed pin holes, the other end is fixedly connected with stay bearing plate, and stay bearing plate is provided with two sleeves, and two sleeves are fixedly connected on the stay bearing plate; L shaped otic placode is two, two L type otic placode upper ends are fixedly connected on the bulkhead respectively with the spacing of setting, two L type otic placode bottoms and hold-down arm opposite position are equipped with pin shaft hole and fixed pin holes, hold-down arm one end that has pin shaft hole and fixed pin holes is put between two L shaped otic placodes, bearing pin is installed in the pin shaft hole of L shaped otic placode and hold-down arm, with opening pin latched position, set pin is installed in the fixed pin holes of L shaped otic placode and hold-down arm; Two bolts are respectively charged in two sleeves, and fixing two bolt tops of Chi below the supporting plate are fixed on above the supporting plate on the manhole cover, with nut with bolted on stay bearing plate, be configured for the service platform that manhole cover is opened and installed.
Establish reinforced plate between two above-mentioned L shaped otic placodes, reinforced plate is fixed on two L shaped otic placodes.
Brace panel is established in above-mentioned hold-down arm both sides, and brace panel is fixedly connected on the hold-down arm both sides, an end captive joint stay bearing plate.
Be connected with below the above-mentioned hold-down arm for unloading the bolt carrying case.
On the ring of above-mentioned set pin chainlet is housed, the chainlet other end is fixed on the L shaped otic placode.
Compared with prior art, the beneficial effect that has of the present invention is:
Travel(l)ing rest of the present invention is when opening and cover plate is installed, hold-down arm and otic placode connect into rigid support by set pin, and cover plate is held, and the crewman does not worry that cover plate falls down when operation, only stubborn bolt just can be operated, the bolt that unloads can be placed in the box, and extracting set pin out can be with the cover plate rotating opening, therefore simple in structure, easy and safe to operate, save the space, when especially workplatform is established in narrow and small cabin inconvenience in the space, have more convenient and safe property.
