The purpose of this utility model provides a kind of light, flexible, quick, safe indoor light-duty removable crane, solves the problem of the restricted construction environment usefulness crane lifting weight in operational spaces such as constructure body structure inside.
For achieving the above object, the utility model adopts following technical scheme: this indoor light-duty removable crane, and its main body suspension bracket is made of arm 2 and chassis 3, it is characterized in that:
Front portion on the chassis 3 connects arm 2, and the rear portion on the chassis is equipped with counterweight 4, connects wheel carrier, two front-wheels 9 and two trailing wheels 10 below the chassis, and wherein two trailing wheels are cardan wheel; Place, four angles on the chassis connects laterally overhanging two front leg struts 8 and two rear support legs 12.
The lower end of arm 2 is hinged by bearing pin 11 and chassis 3, and the head of arm 2 is connected with electronic jack 1, is connected tie-down cable 5 between the preceding middle and lower part of arm 2 and the front end on chassis 3, and connection cable and jack finely tune 7 between the rear end on the upper back of arm 2 and chassis 3.
Optimized technical scheme: above-mentioned arm 2 can be 1 font or A font.
The rear end on above-mentioned chassis can be connected with vertical rod 13.
Between the rear end vertical rod 13 on the upper end of arm 2 and chassis 3, can be connected with safe spare rope 6.
Compared with prior art the utlity model has following characteristics and beneficial effect:
1, in light weight, volume is little, the utility model does not need hydraulic efficiency equipment and control mechanism, overall weight only is 615kg, compact conformation, small investment, with low cost, be particularly useful for the restricted construction environment in operational space such as indoor and use.
2, light and flexible, owing on the chassis of crane four wheels that have bearing are installed, wherein two wheels are cardan wheel, and mobile turning is freely light, and working strength of workers obviously reduces simultaneously, can reduce the workmen, and the integral construction cost also obviously reduces.
3, speed of application is accelerated, because this device has been saved workman's service working times such as bont and repeated disassembled and assembled lifting means are installed of ascending a height, adopt electronic jack as promoting power simultaneously, hoisting speed is 5 times of manual chain hoist, and can shorten one times the non-cutting time that single girder steel is installed.Therefore construction speed is obviously accelerated, and has improved installation effectiveness.
4, construction cost reduces:
Because the quickening of hoisting speed and girder steel are installed the shortening of non-cutting time, operating efficiency is obviously accelerated, and has shortened the duration greatly, has reduced the workmen simultaneously.The integral construction cost obviously reduces.
5, safe and reliable owing to eliminated the potential safety hazard of workman's ascend operation, simultaneously this device in design process all the time with safety as emphasis, take into full account various potential safety hazards and take measures targetedly.For preventing that the rollover phenomenon from appearring in crane when work, at four angles on crane chassis supporting leg is installed respectively, support whole crane by four supporting legs during crane work.For preventing that crane work from the time occurring leaning forward, and adds the work elevation coverage of counterweight and regulation arm at the afterbody of crane.For preventing that the malfunctioning safety misadventure that causes from appearring in arm hawser and jack, before and after suspension arm of crane, add tie-down cable and safe spare rope respectively in addition, make construction safety, reliable.Be applicable to that indoor steel structure sandwich structure is installed and other weight lifting.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
