The bearing device is used for realizing lifting of the article. When the bearing device lifts articles, the counterweight device counteracts a part of weight of the bearing device through the traction rope, and kinetic energy consumed by the kinetic energy device can be reduced, so that power requirements on the kinetic energy device are reduced, equipment cost is reduced, and energy consumption during working is saved.

The technical scheme of the disclosure can be applied to any scene of warehouse logistics, industrial manufacturing or other object lifting function requirements, and lifting or lowering of objects is realized through the bearing device. In some examples, the item varies from one scene to another. For example, in the context of a warehouse logistics, the items may be primordial boxes, cargo boxes, or goods; in the context of industrial manufacturing, the item may be a manufacturing-related material, semi-finished product, tool, or the like. The load bearing apparatus 2 may also be other elements performing a lifting function, such as an elevator car or the like.

The technical solutions of the present disclosure will be described in detail below in connection with specific structures.

In some embodiments of the present disclosure, as shown in fig. 1, 2, the lifting apparatus includes a column 1, and a carrying device 2, a counterweight device 3, and a traction device 4 disposed on the column 1. Wherein, the bearing device 2 moves along the extending direction of the upright post 1 under the drive of the power device; the counterweight device 3 is in sliding fit with the upright 1 and moves along the extension direction of the upright 1. The carrying device 2 and the counterweight device 3 are connected by means of a traction device 4.

The traction device 4 comprises a guide assembly 41 arranged on the upright 1, and a traction rope 42 wound on the pulley assembly 41, wherein one end of the traction rope 42 is connected with the bearing device 2, the other end is connected with the counterweight device 3, and the traction rope 42 is configured to pull the bearing device 2 and the counterweight device 3 upwards. The power device provides power for the bearing device 2, when the gravity is overcome to lift the article, the counterweight device 3 descends downwards along the upright post 1, part of gravity of the bearing device 2 can be offset, and the energy consumption of the power device is saved.

In some embodiments of the present disclosure, as shown in fig. 1, the bearing device 2 and the counterweight device 3 are disposed on opposite sides of the upright 1, so that weights on opposite sides of the lifting device are relatively balanced, and are not easy to topple over, and the overall structure is more stable. In other embodiments, the carrying device 2 and the counterweight device 3 may be arranged at other locations of the upright 1, for example on the same side of the upright 1, or on adjacent sides of the upright 1.

In some embodiments of the present disclosure, the weight of the carrying device 2 is greater than the weight of the counterweight device 3, and in a state where the power device does not provide power, the carrying device 2 has a tendency to slide down, and the falling can be achieved by its own weight.

In one embodiment of the present disclosure, as shown in fig. 3 and 4, the counterweight device 3 includes a counterweight seat 31, and a counterweight 32 and a guide wheel assembly 33 are disposed on the counterweight seat 31. The weight seat 31 serves as a mounting base, and one end of the traction cable 42 is connected to the weight seat 31. The weight 32 may be a relatively heavy material such as a metal block. One side of the upright 1 is provided with a guide groove 11, the extending direction of the guide groove 11 is consistent with that of the upright 1, the guide wheel assembly 33 is in sliding fit in the guide groove 11, and the guide groove 11 plays a role in guiding the movement of the counterweight device 3.

For clarity and brevity of description, the extending direction of the column 1 is referred to as the Z-axis direction in this disclosure, and the X-axis and the Y-axis are defined on a plane intersecting the Z-axis. In the lifting device, the carrying device 2 and the counterweight device 3 are distributed in the X-axis direction, and the guide wheel assembly 33 and the counterweight 32 are distributed in the X-axis direction. In one example as shown in fig. 1, the Z-axis direction is vertical, the planes of the X-axis and Y-axis are horizontal planes, and the column 1 extends vertically, in which example the column 1 extends in the vertical direction. Of course, the Z axis may have a certain inclination angle, so long as the function of lifting or lowering the article by a certain height of the carrying device 2 is satisfied. The planes of the X axis and the Y axis can be horizontal planes, planes perpendicular to the Z axis, or other planes intersecting the Z axis.

In one embodiment of the present disclosure, as shown in fig. 3, the guide wheel assembly 33 includes a first guide wheel 331 and a second guide wheel 332 that are engaged with the inner wall of the guide groove 11. The rotation axis of the first guide wheel 331 extends along the Y-axis direction, and the rotation axis of the second guide wheel 332 extends along the X-axis direction. The first guide wheel 331 can limit the weight device 3 in the X-axis direction, and the second guide wheel 332 can limit the weight device 3 in the Y-axis direction, so that the weight device 3 can only move in the Z-axis direction along the guide groove 11, and is more stable.

In one embodiment of the present disclosure, as shown in fig. 4, opposite sides of the first guide wheel 331 in the X-axis direction are close to the inner wall of the guide groove 11, and a small gap is left between the first guide wheel 331 and the inner wall of the guide groove 11, and the guide groove 11 can limit the first guide wheel 331 in the X-axis direction only with a small moving space. During the movement of the counterweight device 3 along the guide groove 11, the first guide wheel 331 is configured such that one side in the X-axis direction can frictionally roll with the inner wall of the guide groove 11.

In one embodiment of the present disclosure, as shown in fig. 5, the second guide wheels 332 are provided at least two at intervals in the Y-axis direction. The sides of the two second guide wheels 332 away from each other rub against the inner wall of the guide groove 11 and the rotation directions are opposite. The guide groove 11 can thus limit the two second guide wheels 332 in the Y-axis direction.

In one embodiment of the present disclosure, as shown in fig. 3, the first guide wheels 331 and the second guide wheels 332 of the guide wheel assembly 33 are arranged in two rows along the Z-axis direction and distributed in the Y-axis direction, each row including at least one first guide wheel 331 and at least one second guide wheel 332. Preferably, in the two rows of guide wheels, the first guide wheel 331 and the second guide wheel 332 are arranged in pairs, and the two first guide wheels 331 in pairs or the second guide wheel 332 in pairs are located at the same height.

In detail, as shown in fig. 4 and 5, the opening of the guide groove 11 faces the counterweight device 3, and the inner wall of the guide groove 11 facing the guide wheel assembly 33 in the X-axis direction is a first inner wall 111. The guide groove 11 has second inner walls 112 opposite to the first inner walls 111 on both sides of the opening. The first inner wall 111 and the two second inner walls 112 are distributed in the X-axis direction. The guide wheels of two rows are distributed on opposite sides of the opening of the guide groove 11. The first guide wheel 331 is adjacent to the first inner wall 111 and the second inner wall 112 at two opposite sides of the X-axis direction. The opposite two inner walls of the guide groove 11 distributed in the Y-axis direction are third inner walls 113. The second guide wheels 332 distributed at both sides of the opening of the guide groove 11 are respectively friction-fitted with the two third inner walls 113.

Since the first guide wheels 331 have a gap between the inner walls of the guide groove 11 in the X-axis direction, the two pairs of first guide wheels 331 are distributed at relatively far positions, and the stability of the guide wheel assembly 33 in the X-axis direction can be improved.

Specifically, the guide wheel assembly 33 includes four first guide wheels 331 and four second guide wheels 332, and is arranged in two columns within the guide groove 11, each column including two first guide wheels 331 and two second guide wheels 332. The four first guide wheels 331 are paired two by two, and the four second guide wheels 332 are also paired two by two, the paired guide wheels being arranged in the Z-axis direction. One pair of first guide wheels 331 is disposed above the guide wheel assembly 33, the other pair of first guide wheels 331 is disposed below the guide wheel assembly 33, and the two pairs of second guide wheels 332 are disposed at intermediate positions.

In the preferred embodiment, the X-axis and the Y-axis are perpendicular to each other, and the axis of rotation of the first guide wheel 331 is perpendicular to the axis of rotation of the second guide wheel 332.

The two traction ropes 42 are respectively connected to opposite sides of the bottom plate 312 of the counterweight seat 31. The notches of the counterweight 32 that avoid the eye connection 34 are symmetrically arranged to avoid shifting the center of gravity of the counterweight 32 in the Y-axis direction.

In one embodiment of the present disclosure, as shown in fig. 2, the guiding assembly 41 of the traction device 4 may be a pulley assembly, and disposed at the top end of the upright 1, the pulley assembly including two first pulleys 411 that position the traction cable 42, and at least one second pulley 412, the second pulley 412 being disposed between the two first pulleys 411.
