The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Please refer to Fig. 1 to Fig. 3, wherein, Fig. 1 is the structural representation of crash change of speed winch in the utility model the first embodiment; Fig. 2 is the structural representation of crash change of speed winch in the utility model the second embodiment; Fig. 3 is the structural representation of crash change of speed winch in the third embodiment of the utility model.
The utility model provides a kind of crash change of speed winch, for carrying out lifting, elevator and the rolling of object.In the prior art, winch includes frame 1, cylinder 2 and engine installation 3, and rolling can be walked around and is arranged in frame 1.Frame 1 is the main body frame of crash change of speed winch (following referred to as winch), for mounting rotary drum 2.Cylinder 2 is arranged in frame 1 rotationally.Particularly, the two ends of cylinder 2 are provided with rotating shaft, in frame 1, are provided with mounting groove, are arranged with bearing in rotating shaft, and so, cylinder 2 is arranged in frame 1 rotationally by rotating shaft.Cylinder 2 act as the folding and unfolding that realizes rope, one end of rope is fixedly installed on cylinder 2, the other end of rope is connected with object.Engine installation 3 is connected with cylinder 2 power, and when engine installation 3 running, engine installation 3 can rotate by head roll 2, thereby realizes the rotation of cylinder 2, completes the receipts of rope or the action of putting.
Based on said structure design, the crash change of speed winch that the utility model provides also provides change speed gear box 4, and engine installation 3 is connected with cylinder 2 power by change speed gear box 4.Those skilled in the art are known, and engine installation 3 turns round under rating horsepower, and its output speed is definite value, and in the prior art, engine installation 3 is directly connected with cylinder 2, cannot regulate the rotating speed of cylinder 2.In the utility model, by being provided with change speed gear box 4, in engine installation 3 normal operation situations, by change speed gear box 4 is carried out to gear shift operation, can realize the adjusting of engine installation 3 output speeds.So, the winch that the utility model provides, on the basis of existing structure, has been set up change speed gear box 4, can realize the object of cylinder 2 speed adjustment, and greatly degree has improved applicability of the present utility model, meets the operating needs under various working.
In the following embodiments, respectively composition member of the present utility model is limited:
The first, engine installation 3 is oil-burning machine.
The second, change speed gear box 4 is for having quick gear, the three class gear box 4 of gear and reverse gear gear at a slow speed.
So, can make reel there are twirl, slow rotation and three kinds of mode of operations of reversing.When the larger object of quality is carried out to elevator, folding and unfolding, can select the pattern of slow rotation, avoid excessive the impacting compared with the situation that causes greatly job insecurity of object folding and unfolding speed to occur; After object placement has been moved, while only needing to regain rope, can select twirl pattern, thereby accelerate the recovery of rope, increase work efficiency.
Three, chain a is 16-2A chain.
Adopt chain to carry out transmission of power, can improve powerdriven stability, and, make the utlity model has higher structural strength.
Four, frame 1 is channel-section steel welding support.
Channel-section steel has stronger structural strength, adopts channel-section steel to make frame 1 by welding, can improve the structural strength of frame 1.
Particularly, change speed gear box 4 has power intake and clutch end, and power intake is for being connected with engine installation 3, thereby the driving force of realizing engine installation 3 is passed in change speed gear box 4.Because change speed gear box 4 has a plurality of gears, therefore, power intake is castle wheel assembly, and engine installation 3 is by being connected with power intake power.
In a specific embodiment of the present utility model, a side of cylinder 2 is provided with sprocket wheel, and clutch end is connected with sprocket wheel by chain a.Adopt chain a transmission, can improve the precision of the utility model transmission.
In another specific embodiment of the present utility model, engine installation 3 is connected with the power intake of change speed gear box 4 by belt b, adopts belt b to connect, and belt b has to let slip and carries a function, therefore, can avoid engine installation 3 because overload starts situation about being damaged.
In the present embodiment, crash change of speed winch also comprises the brake assemblies for cylinder 2 is braked, and brake assemblies is fixedly installed in frame 1.
Particularly, brake assemblies comprise stretcher, brake disc and can with the braking clamp of brake disc frictional fit, stretcher is connected with braking clamp power, brake disc is fixedly installed on cylinder 2.Stretcher is connected with braking clamp by connecting rod mechanism, realizes the obvolvent of braking clamp by foot-operated effect, and brake disc and braking clamp frictional fit, embrace after brake disc when braking clamp, realizes the deceleration of cylinder 2 by rubbing effect.
A specific embodiment of the present utility model:
This winch simple in structure, mainly consists of engine three parts, change speed gear box 4(shift-variable), cylinder 2, connecting bridge channel-section steel welding support, running part is belt b and chain a, and consideration is heavy load, can join according to load the chain a of 16-2A, with the chain a of 20-2A, change speed gear box 4 minutes is fast, slow, reverse gear, belt b is that engine drives the castle wheel of change speed gear box 4 to rotate, and chain a is sprocket rotation drive winch cylinder 2 rotations by change speed gear box 4, thereby reaches the object of elevator.Can regulate speed according to the weight of object, have reverse gear conveniently and rolling, can reach the effect of the two-direction switch of power electric simultaneously.Cylinder 2 has been installed brake above, can rolling.Operate very simply, if the object of fixed weight, generally just go gearshift, power-transfer clutch can be according to manually operation, also can connect with stretcher pull bar more conveniently, and braking is hand lever, if desired also can make into foot-operated.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
