Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, 2, the utility model is used for weight in building and is transported to the elevator system of roof, and comprise base 3, pallet 5, first lift system, the second lift system, the first lift system, the second lift system promote pallet or decline.
For convenience of mobile, the bottom of base is provided with cardan wheel 4.When carrying out lifting work, for ensureing that position base is fixed, base is also provided with caster loocking device.
First lift system comprises the guidepost 6 be arranged on base, and pallet 5 is set on described guidepost 6, and the first lift system also comprises the first engine installation, and the first engine installation controls pallet 5 and carries out up-and-down movement along guidepost.
Described first engine installation is arranged on the boss 2 at roof opening 1 place, comprise the first motor 77, the spool 73 be connected is driven with the clutch end of the first motor, be set in the reel 71 on described spool 73, and be arranged on the reel disc 72 at described reel 71 two ends, wherein said reel disc 72 is arranged on roller stand 74, reel 71 is provided with steel rope 76, one end of described steel rope 76 is fixed on reel 71, the other end is fixed on the center position of pallet 5, two winding drum dish is fixedly installed guiding trestle 75, described guiding trestle is provided with the pilot hole 75a for steel rope guiding.First motor is variable-frequency motor.
First motor 77 drives spool 73 to rotate, and spool 73 is with movable reel 71 to rotate, and the steel rope 76 on reel 71 is wound around, thus drives pallet 5 upward movement.When mounted, for ensureing that the pulling force of the steel rope that pallet is subject to is all the time perpendicular to base, is connected with pallet after pilot hole described in steel wire penetrating again, pilot hole makes the pulling force of steel rope to pallet be always vertical direction, is conducive to pallet and keeps balance.
Because reel is arranged on the boss of roof opening part, after pallet rises to roof opening part under the effect of the first lift system, reel and pallet are apart from very near, reel cannot carry out lifting work to pallet again, can only manual operation but take off weight on pallet, because little in the space of roof opening part, the bad operation of machine tool, which not only adds labour power, add construction risk.Therefore the utility model adopts the second lift system again to promote pallet, is promoted to roof overthe openings, and roof overthe openings space is open, machine tool can be utilized to take off weight on pallet, not only reduce work degree, and safer.
The second motor 85 that second lift system comprises the umbrella gear box 83 be arranged on base, the revolving bar be connected with the clutch end power of umbrella gear box 83, the transmission shaft 84 be connected with the power intake power of described umbrella gear box and is connected with described transmission shaft power.Wherein said revolving bar and described guidepost 6 be arranged in parallel, and described pallet 5 is set on described revolving bar, described revolving bar comprises the threaded screw rod 82 and slide bar 81 that are fixedly connected sequentially from top to bottom, the Major Diam of described threaded screw rod 82 is greater than the diameter of described slide bar 81, described pallet is provided with the negative thread suitable with the outside thread of described threaded screw rod, the length of described threaded screw rod 82 is 1/5 of described slide bar 81 length, and the length of threaded screw rod is 60cm.
When pallet upwards promotes along slide bar, the first motor 77 is operative condition, and the second motor 85 is halted state.When threadingly screw mandrel upwards promotes pallet, the second motor 85 is operative condition, and the first motor 77 is halted state.When pallet is along slide bar upward movement, due to the negative thread of pallet and the outside thread of threaded screw rod suitable, and the Major Diam of threaded screw rod is greater than the diameter of slide bar, the diameter at bottom of thread of pallet is greater than the diameter of slide bar, and pallet can along guidepost and slide bar upward sliding under the drive of steel rope.When in tray motion to threaded screw rod, second driven by motor transmission shaft driven, transmission shaft is rotated by umbrella gear box driven rotary bar, because pallet and threaded screw rod are for being threaded, therefore pallet upwards does straight-line motion relative to base, when pallet arrives a certain position, the top of roof opening, stop the second motor, pallet stops upward movement.
Because the utility model has two motors, timesharing provides power for pallet.For convenience of controlling, the boss of roof opening part is provided with lifting position-limit bar 9a, descending spacing bar 10a, the lifting position-limit switch 9b corresponding with lifting position-limit bar, the descending spacing switch 10b corresponding with descending spacing bar.Described lifting position-limit switch is connected with the first motor, the second motor respectively, and described descending spacing switch is also connected with the first motor, the second motor respectively.
First, the first motor drives reel to rotate forward, pallet upward sliding, and when pallet arrives roof opening part, pallet touches lifting position-limit bar, and lifting position-limit bar touches lifting position-limit switch, and lifting position-limit switch makes the first motor shut down, the second motor is opened.Then, the second motor drives threaded screw rod to rotate forward, and pallet continues upward movement, arrives the top of roof opening.Certainly, decline process is the inverse process of above-mentioned uphill process, first, second motor drives threaded screw rod reversion, pallet declines, and when pallet arrives roof opening part, pallet touches descending spacing bar, descending spacing bar touches descending spacing switch, the second motor is shut down, first motor open.Then, under the driving of the first motor, reel reverses, and pallet continues to move downward, and reaches base.
The utility model utilizes the first lift system weight be promoted in building roof opening part or drop in building base from roof opening 1, utilizes the second lift system weight is promoted to the top of roof opening from roof opening part or drops to roof opening part from the top of roof opening.Utilize the switching of lifting position-limit switch and descending spacing switch control rule first motor and the second motor, handoff procedure does not need manual operation, and conveniently takes off weight, safe and reliable.
Above; be only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
