Abstract
The utility model discloses a hoister which belongs to a building machine, composed of a motor, a speed reducer, a differential mechanism and two drums. The differential mechanism is arranged between the speed reducer and the two reels, and the differential mechanism can output a moment which is from the speed reducer to the two reels through both ends respectively. The utility model has the advantages of low cost and high safety.
Description
The utility model relates to a kind of vehicle for construction, especially a kind of safe differential speed type twin drum winch.
The actuating unit that is applied to the elevator of building operation at present mainly contains two kinds: a kind of is winch, generally can only work alone by steel cable, so its safety factor is not high.When running into overload, steel cable disconnects and just causing the accident.Second kind is towing machine, and it is the traction type of belt drive with reference to indoor manned elevator, and this class towing machine is applied on the building hoist, uses 3～5 steel ropes to work independently of each other, and its safety factor is very big, and the probability that disconnected rope occurs is very little.But involve great expense, particularly the consumption of steel rope is 12 times more than (in four ropes) of the single rope of equal height winch.So difficulty is promoted the use of in building operation.
The purpose of this utility model provides a kind of both safety, and the winch that cost is low again is to satisfy the needs of building operation.
For achieving the above object, the utility model adopts the form of the two reels of duplex type, makes two steel ropes can be independent, and elevator synchronously.In order to solve two difficult points that the steel rope load is synchronous, the utility model has been installed a diff between two reels, makes two reels reach the load that is equal to by different rotating speeds, make two separate work of steel rope, and load is identical all the time.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Integral structure figure when Fig. 2 is applied to elevator for the utility model.
Drawing explanation: 1 reel I, 2 bearing seats, 3 difies, 4 retarders, 5 drgs, 6 motors, 7 reel II, 8 erosion control ejection devices, 9 steel rope I, 10 steel rope II, 11 well cabinet frames, 12 cages.
With reference to Fig. 1, the utility model comprises reel (1,7), bearing seat (2), retarder (4), drg (5) and motor (6), these are similar to traditional winch, and innovation part of the present utility model is to use two reels (1,7), are provided with diff (3) between retarder (4) and two reels (1,7).
In addition, for greater safety, each reel also can be provided with drg.
Described diff (3) can use automobile differential.
Structural principle of the present utility model and working process are as follows:
Motor (6) provides propulsion source, slows down and raising moment through retarder (4).By diff (3) the torque distribution of the back input of slowing down to two output shafts, and two output shafts can be rotated with different cireular frequencys.Be used for hoisting rope with two output shaft bonded assembly two winding drums (1,7).
During use, electric motor starting is exported certain torque, slows down through retarder, and input diff A end is exported respectively by B, the C two ends of diff again, drives two reels and rotates.
Be applied to building hoist, as shown in Figure 2.Two steel ropes (9,10) are fixed on the interior bird cage (12) of well cabinet frame (11) together.Under the normal circumstances, the load of two steel ropes is the same, and the rotating speed of two reels is also identical.When because certain factor, the load that causes steel rope I is during greater than the load of steel rope II, and the rotating speed of reel I can reduce, and the faster rotational speed of reel II, like this, steel rope will strengthen, and the load of steel rope I then reduces, and equates that until both vice versa.Two reels of whole elevator process remain synchronously, and it is identical that the load of two steel ropes also always is tending towards.Just in case wherein steel cable disconnects, also have an independent traction, safe and reliable to guarantee.
The utility model uses two reel double-steel wire ropes, and is more much lower than towing machine cost, is easy to promote; Two winding drum and two steel ropes are separate work, can guarantee production safety; Diff can the balance two winding drum rotating speed and two steel ropes stressed, more improved safe reliability of the present utility model.
Claims (3)
1. a differential speed type bitubular building whim comprises reel (1,7), bearing seat (2), retarder (4), drg (5) and motor (6) is characterized in that: use two reels (1,7), be provided with diff (3) between retarder (4) and two reels (1,7).
2. differential speed type bitubular building whim according to claim 1, it is characterized in that: each reel also can be provided with drg.
3. differential speed type bitubular building whim according to claim 1 is characterized in that: described diff (3) can use automobile differential.
