Detailed description of the invention
As in Fig. 1,2, a kind of multilayer construction hanging basket, comprises support 1, and support 1 is provided with at least two-layer working platform, is provided with working stand 2 between working platform; Upper strata working platform 3 is provided with working stand import 31, is convenient to personnel and enters, as shown in Fig. 5,6.
The roller for sliding along construction is provided with at the back side of support 1, construction in this example has a cell wall tilted, the roller arranged makes whole hanging basket slide along cell wall in lifting process, roller in this example adopts telescopic roller, can by flexible roller, adjust the inclined degree of whole hanging basket, be beneficial to make working platform to keep level, putting of constructability operation and equipment.By above-mentioned structure, realize multiple benches face and construct simultaneously.
The two ends of working platform are provided with the flexible working platform 5 be flexibly connected with working platform, construct for stretching in gate slot.As shown in Fig. 1,3,4, the left side in figure is the structure of flexible working platform 5 when not stretching out, and the right side in figure is the structure of flexible working platform 5 when stretching out.
The locating wheel 13 pointing to both sides is provided with at support 1 or working platform.Structure thus, limits the right position of hanging basket, avoids whole hanging basket to swing in construction.
Emergency gate slot is the oblique door groove of slope than 1:0.15, gate slot domestic demand carries out the construction of door track built-in fitting, for ease of construction, the base plate 10 of the working platform in this example is for being horizontally disposed with, the base plate 10 of the working platform namely in this example is relative to support out of plumb, but have corresponding inclination angle according to the angle of inclination of oblique door groove, to make the base plate 10 of working platform for level, be convenient to personnel's walking, construction and putting equipment.
As in Fig. 1,2,7,8, support 1 is installed with winding plant, and winding plant is connected with suspension 14 by wire rope 8.Structure thus, realizes the descending operation of whole hanging basket, winding plant is arranged on the operation at the scene of being more convenient on support 1.
As in Fig. 1,2, in described winding plant, the elevator motor 6 be installed on support 1 is connected with worm gear reducer 11, and the output shaft of worm gear reducer 11 is connected with wire rope roller, and wire rope 8 is wound on wire rope roller.The worm gear reducer 11 arranged is convenient to realize self-locking, improves safety.
As in Fig. 1,2, described wire rope 8 is through the limit for tonnage safety lock 7 be installed on support 1.Structure thus, when whole hanging basket exceedes the safe bearing load of setting, limit for tonnage safety lock 7 can pin winding plant, and reports to the police, thus guarantees construction safety.
As in Fig. 9, in described limit for tonnage safety lock 7, the first round 72, second takes turns 74 and straining pulley 75 interlaced arrangement from top to bottom, wherein straining pulley 75 is taken turns between 74 in the first round 72 and second, state walks around the first round 72 to wire rope 8 successively into a bent shape, straining pulley 75 and second takes turns 74, and straining pulley 75 is provided with force snesor 73.Structure thus, the pulling force received when wire rope 8 strengthens, then the bending degree of wire rope 8 reduces, and obtains this change, reaches setting value, can disconnect the power supply of winding plant by force snesor 73, in preferred scheme and locking steel wire rope.
The structure of force snesor 73 is: the wheel shaft 78 of straining pulley 75 is positioned at slotted eye 76, and wheel shaft 78 side is provided with spring 77, to make straining pulley 75 press to wire rope 8, wheel shaft 78 is provided with pressure sensor, or wheel shaft 78 is connected with the pulling force sensor set firmly.Force snesor 73 is connected with the control device of winding plant, such as PLC, when PLC receives the data of force snesor 73 acquisition, compare with the data preset, when exceeding preset value, then PLC disconnects the power supply of elevator motor 6, worm gear reducer 11 self-locking, same to alarm, guarantees construction safety.
In another optional scheme, the structure of force snesor 73 is: the wheel shaft 78 of straining pulley 75 is positioned at slotted eye 76, wheel shaft 78 side is provided with spring 77, to make straining pulley 75 press to wire rope 8, is also provided with the travel switch triggered by straining pulley 75 or wheel shaft 78, travel switch makes elevator motor 6 power-off after triggering, such as travel switch is arranged on the position of spring 77 in Fig. 9, acquires a certain degree when wire rope 8 stretches, then trigger travel switch, make elevator motor 6 power-off, and it is electric that alarm buzzer is obtained.Adopt this structure, then without the need to using PLC to realize, be conducive to reducing use cost.
