As shown in fig. 1 and fig. 2, an embodiment of the hoisting device includes an arm support 100, a hoisting mechanism 200, and a leveling member 300.

The boom 100 can be extended and contracted, and the boom 100 can be moved supinely in the vertical direction.

With reference to fig. 1 and 3, the hoisting mechanism 200 includes a fixed frame 210 and a hoisting assembly 220, the fixed frame 210 is rotatably connected to the boom 100, and the hoisting assembly 220 includes a rotary driving member 223 disposed on the fixed frame 210, a revolving frame 221 drivingly connected to the rotary driving member 223, and a spreader 222 connected to the revolving frame 221.

Specifically, the fixing frame 210 is an installation base of the whole lifting mechanism 200, the fixing frame 210 is hinged below the arm support 100, and when the arm support 100 extends or retracts or moves supinely, the whole lifting mechanism 200 can be driven to move through the fixing frame 210.

The rotary drive 223 can drive the revolving frame 221 to rotate relative to the fixed frame 210, and thus, the revolving frame 221 can be rotated by the rotary drive 223, so that the spreader 222 can be rotated. When the spreader 222 lifts a container, the spreader 222 is driven to rotate by the rotary drive 223, whereby the container can be inverted, and flexibility is high.

Further, the revolving frame 221 and the fixing frame 210 are disposed at an interval, the revolving frame 221 is located outside the fixing frame 210, the hanger 222 is disposed on a side of the revolving frame 221 away from the fixing frame 210, and a revolving bearing 230 is disposed between the fixing frame 210 and the revolving frame 221. By means of the pivot bearing 230, the pivoting frame 221 can be connected to the holder 210 on the one hand, and the pivoting frame 221 can be pivoted relative to the holder 210 on the other hand.

Specifically, the rotary drive member 223 is a reduction motor, and an external gear 2231 is fixed to an output shaft of the rotary drive member 223; the slew bearing 230 is an internally toothed slew support bearing; the external gear 2231 meshes with the internal teeth of the internal-tooth slewing support bearing. When the rotary driving member 223 is started, the rotary bearing 230 can drive the rotary frame 221 to rotate relative to the fixed frame 210.

In the present embodiment, the turret 221 is capable of 360 ° rotation by the rotary drive 223.

Further, when the spreader 222 lifts the container, the center of gravity of the container coincides with the rotation center of the spreader 222, so that the influence of the torque generated by the eccentricity on the boom 100 can be eliminated, and the weight of the weight that can be lifted by the entire lifting device is increased.

One end of the leveling member 300 is connected with the arm support 100, the other end of the leveling member 300 is in driving connection with the fixing frame 210, and the leveling member 300 is used for leveling the whole lifting mechanism 200 through the fixing frame 210.

Specifically, when the spreader 222 lifts containers with different weights, the center of gravity of the whole formed by the lifting mechanism 200 and the containers is different, which may cause the fixed frame 210 to deflect relative to the arm support 100, and the whole lifting mechanism 200 can be leveled by adjusting the fixed frame 210 by using the leveling member 300, so that the container lifted by the spreader 222 is leveled. In addition, when the elevation angle of the boom 100 changes, the fixing frame 210 may also deflect relative to the boom 100, and similarly, the lifting mechanism 200 may also be leveled by the leveling member 300.

After the lifting mechanism 200 swings in a first direction relative to the boom 100 due to gravity, the leveling member 300 can drive the lifting mechanism 200 to swing in a second direction opposite to the first direction relative to the boom 100 to level the lifting mechanism 200.

More specifically, the leveling member 300 is a telescopic driving member, and one end of the leveling member 300 is rotatably connected to the arm support 100, and the other end is rotatably connected to the fixing frame 210. Thus, when the leveling member 300 is not extended, the leveling member 300 can fix the fixing frame 210, so that the hoisting mechanism 200 is prevented from shaking too much when moving under the action of the boom 100, and when the hoisting mechanism 200 deflects, the leveling member 300 can also achieve a leveling effect.

Optionally, the leveling member 300 is an oil cylinder, and specifically, in fig. 1, if the lifting mechanism 200 swings counterclockwise due to gravity, the telescopic shaft of the oil cylinder extends out to drive the lifting mechanism 200 to deflect clockwise, so as to level the lifting mechanism 200.

Referring to fig. 3 and 5, the fixing frame 210 is provided with a first through hole 211, the rotating frame 221 is provided with a second through hole opposite to the first through hole 211, the wire tube 240 penetrates through the first through hole 211 of the fixing frame 210 and the second through hole of the rotating frame 221, and at least one of the fixing frame 210 and the rotating frame 221 is movably matched with the wire tube 240.

Because the rotary frame 221 is rotatable relative to the fixing frame 210, the wire tube 240 is inserted through the first through hole 211 of the fixing frame 210 and the second through hole of the rotary frame 221, and at least one of the fixing frame 210 and the rotary frame 221 is movably matched with the wire tube 240, so that the wire tube 240 can be prevented from interfering the rotary frame 221 to rotate relative to the fixing frame 210.

Further, the second through hole of the turret 221 is disposed coaxially with the rotation center axis of the turret 221. Thus, when the rotary driving member 223 drives the rotary frame 221 to rotate, the position of the second through hole is not changed.

The conduit 240 is used for the cable to pass through. Specifically, in the transportation vehicle, some cables need to extend from the rear of the fixing frame 210 to the front of the revolving frame 221, and after the cables are directly extended from the rear of the fixing frame 210 to the front of the revolving frame 221 through the wire conduit 240, when the revolving frame 221 rotates relative to the fixing frame 210, the cables cannot be wound under the driving of the revolving frame 221, and the cables can be prevented from being pulled apart.

The blocking member 250 is used to block the gap between the hole wall of the first through hole 211 and the outer sidewall of the conduit 240, and/or the blocking member 250 is used to block the gap between the hole wall of the second through hole and the outer sidewall of the conduit 240. Thus, the blocking member 250 can prevent foreign objects from entering the region between the fixing frame 210 and the rotating frame 221, and prevent the region between the fixing frame 210 and the rotating frame 221 from accumulating foreign objects, thereby preventing the foreign objects from affecting the rotation of the rotating frame 221 relative to the fixing frame 210.

Specifically, in the present embodiment, the rotary bearing 230 is located between the fixed frame 210 and the revolving frame 221, the object blocking member 250 can prevent the impurities from entering the rotary bearing 230, and the rotary bearing 230 and the external gear 2231 are driven by meshing, so that the object blocking member 250 can prevent the impurities from entering the rotary bearing 230, thereby preventing the impurities from being stuck between the internal teeth of the rotary bearing 230 and the external gear 2231, avoiding the occurrence of the stuck condition, and improving the reliability of the operation of the device.

Referring to fig. 4 and 5, in one embodiment, the blocking member 250 is connected to a side of the fixing frame 210 away from the rotating frame 221, the blocking member 250 is sleeved outside the conduit 240, and the conduit 240 is rotatable relative to the blocking member 250. Thus, the blocking member 250 can block the gap between the hole wall of the first through hole 211 and the outer sidewall of the wire tube 240, and the wire tube 240 can rotate relative to the blocking member 250 without affecting the rotation of the rotating frame 221 relative to the fixing frame 210.

Specifically, the object blocking member 250 is provided with an avoiding hole, the line pipe 240 rotatably penetrates through the avoiding hole, and the outer side wall of the line pipe 240 is in sealing fit with the hole wall of the avoiding hole.

It should be noted that, the sealing engagement between the outer sidewall of the conduit 240 and the hole wall of the avoiding hole may mean that a small gap is formed between the outer sidewall of the conduit 240 and the hole wall of the avoiding hole, so that the conduit 240 can rotate relative to the blocking object 250, and in addition, foreign objects cannot enter between the fixing frame 210 and the revolving frame 221 through the small gap; the outer side wall of the conduit 240 is in sealing fit with the hole wall of the avoiding hole, which means that the outer side wall of the conduit 240 is attached to the hole wall of the avoiding hole, but the conduit 240 is still rotatable relative to the stopper 250.

Optionally, the conduit 240 is a wear resistant pipe and the stop 250 is a nylon member.

Further, the lifting mechanism 200 further includes a first fastening member 251, the object blocking member 250 is provided with a first assembling hole, the fixing frame 210 is provided with a second assembling hole opposite to the first assembling hole, and the first fastening member 251 is disposed in the first assembling hole and the second assembling hole in a penetrating manner. In this way, the blocking object 250 can be fixed on the fixing frame 210 by the first fastener 251.

Alternatively, the first fastener 251 is a bolt, the first fitting hole is a through hole, and the second fitting hole is a threaded hole.

Further, a connecting member 260 is connected to an end of the conduit 240 close to the revolving frame 221, and the connecting member 260 is connected to a side of the revolving frame 221 away from the fixing frame 210. In this manner, the conduit 240 can be connected to the turret 221 by means of the connector 260.

Specifically, the wire tube 240 is inserted into the second through hole of the revolving frame 221 and connected to the revolving frame 221 through the connecting member 260. Wherein the outer sidewall of the conduit 240 forms a seal with the wall of the second through hole.

Further, the connecting member 260 is sleeved outside the conduit 240.

Alternatively, the connector 260 and the conduit 240 may be fixedly or movably connected.

In one embodiment, the hoisting mechanism 200 further includes a second fastening member 261, the connecting member 260 is provided with a third assembling hole, the revolving frame 221 is provided with a fourth assembling hole opposite to the third assembling hole, and the second fastening member 261 is inserted into the third assembling hole and the fourth assembling hole.

Alternatively, the second fastening member 261 is a bolt, the third assembly hole is a through hole, and the fourth assembly hole is a threaded hole.

As shown in fig. 1 to 5, in the hoisting device, the fixed frame 210 is a mounting base of the whole hoisting mechanism 200, the revolving frame 221 is rotatable relative to the fixed frame 210, the hoist 222 is disposed on a side of the revolving frame 221 away from the fixed frame 210, and when the revolving frame 221 is driven by the rotary drive 223 to rotate relative to the fixed frame 210, the hoist 222 can be rotated. Thus, under the condition that the container is forked by the spreader 222, the revolving frame 221 can drive the spreader 222 to rotate when rotating, so as to turn over the container, so that the goods in the container can be dumped out, and the flexibility is high.

Moreover, since the rotary frame 221 is rotatable relative to the fixing frame 210, the conduit 240 is inserted through the first through hole 211 of the fixing frame 210 and the second through hole of the rotary frame 221, and at least one of the fixing frame 210 and the rotary frame 221 is movably matched with the conduit 240, so that the conduit 240 can be prevented from interfering the rotation of the rotary frame 221 relative to the fixing frame 210.

The blocking member 250 can prevent foreign objects from entering the region between the fixing frame 210 and the rotating frame 221, and prevent the region between the fixing frame 210 and the rotating frame 221 from accumulating foreign objects, thereby preventing the foreign objects from affecting the rotation of the rotating frame 221 relative to the fixing frame 210.

In addition, when the spreader 222 lifts containers with different weights, the center of gravity of the whole formed by the lifting mechanism 200 and the containers in a matching manner is different, so that the fixed frame 210 deflects relative to the arm support 100, and the whole lifting mechanism 200 can be leveled by adjusting the fixed frame 210 by using the leveling member 300, so that the container lifted by the spreader 222 is leveled, and the reliability is high.

An embodiment also relates to a means of transport comprising a lifting device as described above.

Thus, under the condition that the container is forked by the spreader 222, the revolving frame 221 can drive the spreader 222 to rotate when rotating, so as to turn over the container, so that the goods in the container can be dumped out, and the flexibility is high.

The conduit 240 is used for the cable to pass through. Specifically, on the transportation device, some cables need to extend from the rear of the fixing frame 210 to the front of the revolving frame 221, and after the cables are directly extended from the rear of the fixing frame 210 to the front of the revolving frame 221 through the wire conduit 240, when the revolving frame 221 rotates relative to the fixing frame 210, the cables cannot be wound under the driving of the revolving frame 221, and the cables can be prevented from being pulled apart.
