The axis that described movable pulley 1031 and described fixed pulley 1032 rotate is parallel to each other;
Described transmission rope 104 around on described fixed pulley 1032 and described movable pulley 1031, and when described expansion link 102 moves reciprocatingly, can drive the weight that will lift to move reciprocatingly thereupon.
When specific implementation, Power Component 101 can be hydraulic cylinder, and expansion link 102 can be piston rod, and piston rod in the cylinder body of hydraulic cylinder, under the effect of hydraulic pressure, can do the straight reciprocating motion of the axis along piston rod.Power Component can also be that other can provide the equipment of mechanical energy, such as motor, and the power transmission shaft of motor is connected with expansion link 102 by gear, chain, controls expansion link 102 does straight line reciprocating motion along the axis of expansion link 102.In addition, Power Component can also be that other energy can be changed into the equipment of mechanical energy by other, moves reciprocatingly along the axis of expansion link 102 as long as can control expansion link 102.
Meanwhile, when Power Component 101 be hydraulic cylinder, expansion link 102 for piston rod time, the present invention also comprises with the lifting appliance provided the control pumping plant that promising hydraulic cylinder provides power; Described control pumping plant drives at least one hydraulic cylinder.Control pumping plant can provide power for multiple hydraulic cylinder simultaneously, and each hydraulic cylinder can drive a weight to do the motion promoting decline or push-and-pull, as long as and in certain distance, produce the weight of displacement repeatedly, the device that the present embodiment provides can drive.
In addition, when specific implementation, described transmission rope 104 one end is fixedly connected on described expansion link 102 one end away from described Power Component 101, or is fixedly connected on described Power Component 101; The other end of described transmission rope is for connecting the weight that will lift.When concrete connection, directly the end of transmission rope 104 with expansion link 102 can be connected, also can fixedly mount an installation component on expansion link, then transmission rope is fixedly connected with this installation component.In addition, when movable pulley and fixed pulley have multiple time, in order to keep balance, transmission rope can also be arranged on axle that movable pulley is connected with expansion link, movable pulley and this axle are rotationally connected, and the quantity of the movable pulley of transmission rope both sides is equal; Or be arranged on by transmission rope on axle that fixed pulley is connected with Power Component, fixed pulley and Power Component are rotationally connected by this axle, and the quantity of the fixed pulley of transmission rope both sides is equal.
In assembly pulley, movable pulley 1031 can have one, also can be multiple; When movable pulley 1031 has multiple time, the axis of multiple movable pulley 1031 all overlaps.Fixed pulley 1032 can have one, also can be multiple, and when fixed pulley 1032 has multiple time, the axis of multiple fixed pulley 1032 all overlaps.
The quantity of described fixed pulley 1032 is equal with the quantity of described movable pulley 1031;
Or, many one of the quantity of movable pulley 1031 described in the number ratio of described fixed pulley 1032;
Or, few one of the quantity of movable pulley 1031 described in the number ratio of described fixed pulley 1032.
When specific implementation, shown in Figure 2, when fixed pulley 1032 and movable pulley 1031 all have one time, one end of transmission rope 104 is fixedly connected on expansion link 102 one end away from Power Component 101, because movable pulley itself is also arranged on expansion link 102 one end away from Power Component 101, in order to ensure when expansion link 102 moves reciprocatingly, transmission rope can be made also to drive the weight that will lift to move reciprocatingly thereupon, then transmission rope 104 first to be walked around the fixed pulley 1032 be arranged on Power Component 101, and then walk around the movable pulley 1031 be arranged on expansion link 102, and then be connected with the weight that will lift, like this, when Power Component 101 control expansion link 102 move reciprocatingly time, expansion link 102 drives movable pulley 1031 to move reciprocatingly, be equivalent to the distance increasing or reduce between fixed pulley 1032 and movable pulley 1031, and transmission rope 104 is around on fixed pulley 1032 and movable pulley 1031, and then, time distance between fixed pulley 1032 and movable pulley 1031 changes, transmission rope between fixed pulley 1032 and movable pulley 1031 also needs to elongate or reduce, the reciprocating motion of fixed pulley, drive the motion of transmission rope 104, and then the weight be connected on transmission rope 104 also moves reciprocatingly thereupon.In this process, because the part of transmission rope 104 between movable pulley 1031 and fixed pulley 1032 has two sections, therefore when the move distance of movable pulley 1031 is 1, then the stroke of weight that transmission rope 104 lifts is 2.
In addition, it should be noted that, one end of transmission rope 104 can also be fixedly connected on Power Component 101, as long as can ensure to control in expansion link 102 moves reciprocatingly at Power Component 101, changing appears in the distance between movable pulley 1031 and fixed pulley 1032.
In addition, shown in Figure 3, when the quantity of fixed pulley 1032 and movable pulley 1031 is equal, and when all having two, be respectively the first fixed pulley 10321, second fixed pulley 10322, first movable pulley 10311, second movable pulley 10312, one end of transmission rope 104 is fixedly connected on expansion link 102 one end away from Power Component 101, transmission rope 104 is wrapped in the first fixed pulley 10321, second fixed pulley 10322, first movable pulley 10311, on second movable pulley 10312 as shown in Figure 3, the first fixed pulley 10321 walked around successively by transmission rope 104, first movable pulley 10311, second fixed pulley 10322 and the second movable pulley 10312, finally drawn by the second movable pulley 10312, be connected with weight, when expansion link 102 is controlled by Power Component 101, when doing the reciprocating motion along expansion link axis, there is change in the distance between movable pulley 1031 and fixed pulley 1032, the length of transmission rope 104 between the two changes thereupon, thus the weight be connected with transmission rope 104 is promoted or is transferred.Now, because the transmission rope between movable pulley 1031 and fixed pulley 1032 has four sections, if therefore the stroke of movable pulley is 1, then the stroke that weight is promoted or transfers is 4.Wherein, it should be noted that, the method that transmission rope 104 walks around movable pulley 1031 and fixed pulley 1032 has multiple, such as in the present embodiment, the method that transmission rope 104 is wound around can also be: successively around on the second fixed pulley 10322, second movable pulley 10312, first fixed pulley 10321, first movable pulley 10311, finally draw from the first movable pulley 10311, connect weight.
In addition, shown in Figure 4, when one end of transmission rope is connected on Power Component 101 time, the winding method of transmission rope can be: successively around on the first movable pulley 10311, first fixed pulley 10321, second movable pulley 10312, second fixed pulley 10322, finally draw from the second fixed pulley 10322, connect weight.In addition, the winding method of transmission rope can also be: successively around on the second movable pulley 10312, second fixed pulley 10322, first movable pulley 10311, first fixed pulley 10321, finally draws from the first fixed pulley 10321, connects weight.
When movable pulley 1031 and fixed pulley 1032 more time, be also similar to above-mentioned situation.Again do not repeating.
In addition, the quantity of movable pulley 1031 and fixed pulley 1032 can also be unequal, and generally, both quantity differences are 1.Many one of the quantity of movable pulley described in the number ratio of i.e. described fixed pulley, or few one of the quantity of movable pulley described in the number ratio of described fixed pulley.Now, if the quantity of the number ratio movable pulley of fixed pulley is many, then transmission rope 104 is connected on expansion link, if the quantity of the number ratio movable pulley of fixed pulley is few, then transmission rope 104 is connected on Power Component, namely, which side quantity is few, and which side transmission rope 104 is connected to.
In addition, consider that expansion link 102 only has one end to have annexation with Power Component 101, if when installation lifting appliance, the plane orthogonal at movable pulley and fixed pulley place is in ground, so just easily sliding bar part is caused to fix, therefore, in lifting appliance provided by the present invention, also include the deflecting roller of the transmission direction for changing transmission rope 104; Described transmission rope 104 also for walking around described deflecting roller 105, is connected with the weight that will promote.
When specific implementation, shown in Figure 1, deflecting roller is arranged on the extended line at axis place of expansion link 102, when assembly pulley 103 walked around by transmission rope, after drawing in follow-up pulley 1031 or fixed pulley 1032, walk around deflecting roller 105 again, and then be connected with weight, thus change the transmission direction of transmission rope.Deflecting roller 105, when concrete setting, can carry out concrete setting according to actual conditions, such as, the axes normal fixed pulley of deflecting roller or the axis of movable pulley can be made to arrange.
Consider when lifting heavy, in order to keep balance, generally can connect two transmission ropes 104 on weight, therefore the application also provides another embodiment, shown in Figure 1, and in the lifting appliance that the present embodiment provides, described assembly pulley has two groups; Described transmission rope 104 has two; One group of assembly pulley walked around respectively by two transmission ropes 104; Movable pulley 1031 in assembly pulley described in two groups is arranged along the axisymmetrical of described expansion link 102; Fixed pulley 1032 in assembly pulley described in two groups is arranged along the axisymmetrical of described Power Component 101.A described deflecting roller 105 walked around respectively by two described transmission ropes 104; And described deflecting roller 105 is arranged on the extension line of the axis of described expansion link 102, and lay respectively at the two ends of expansion link 102.When specific implementation, owing to being that two groups of assembly pulleys are connected with an expansion link, therefore Power Component is when control expansion link moves reciprocatingly, the movable pulley in two assembly pulleys can be driven to be synchronized with the movement, again because the axisymmetrical of the movable pulley 1031 in assembly pulley described in two groups along described expansion link 102 is arranged; Fixed pulley 1032 in assembly pulley described in two groups is arranged along the axisymmetrical of described Power Component 101, namely in two groups of assembly pulleys, distance between movable pulley and fixed pulley is equal, therefore around the transmission rope in two groups of assembly pulleys lift weight in, stroke is consistent.
In addition, lifting appliance is will by heavy lift to higher position, generally speaking, lifting appliance is the top being fixed on this raised position, therefore consider and lifting appliance can be fixed easily with higher wall etc., also lifting appliance is made when in use, do not disturbed by the environment in the external world, the lifting appliance that the application provides also includes housing 106, and it is inner that described Power Component 101, expansion link 102, assembly pulley, transmission rope 104 and deflecting roller 105 are all arranged on described housing 106; The sidewall of described housing 106 is also provided with the driving hole 107 passed for transmission rope 104.
