Description

Technical Field

[0001] The utility model relates to a stacker, in particular to a combined walking mechanism of the stacker. Background Art

[0002] The minimum pickup height of the stacker is limited by the chassis height. In order to achieve the designed wheel pressure, especially for heavy-load stackers, the diameter of the traveling wheels is relatively large, and currently the driving force and guide wheels are separately installed on the chassis, which requires a larger chassis space. Utility Model Content

[0003] In view of the defects in the prior art, the utility model provides a combined walking mechanism of a stacker, which can select smaller driving wheels, thereby reducing the height of the chassis.

[0004] The combined walking mechanism of the stacker provided by the utility model comprises: a frame body composed of two triangular brackets arranged symmetrically on the left and right, the upper ends of the two triangular brackets are connected by a rotating shaft, a mounting shaft is arranged on the rotating shaft, and the rotating shaft and the mounting shaft have a "cross" structure; the front section and the rear end of the frame body are both provided with walking wheels; the frame body is also provided with guide wheels and anti-tipping wheels.

[0005] The combined walking mechanism of the stacker provided by the utility model has the following beneficial effects: 1. There are walking wheels at both the front and rear ends of the frame, which increases the number of walking wheels, reduces the wheel pressure of a single wheel, thereby reducing the diameter of the walking wheels and lowering the chassis height; 2. Through the rotatable frame, the wheels are evenly stressed, which ensures the stability of walking and avoids overload of the walking wheels; 3. The walking wheels, anti-tipping wheels and guide wheels are all integrated on the frame, with a compact structure, which improves space utilization, reduces the chassis height, and is easy to disassemble and assemble, and convenient for maintenance.

[0006] According to an embodiment of the present invention, two running wheels are provided at the front and rear ends of the frame.

[0007] According to an embodiment provided by the utility model, there are two guide wheels which are symmetrically arranged on the left and right.

[0008] According to an embodiment of the present invention, there are two anti-tipping wheels which are symmetrically arranged on the left and right.

[0009] According to an implementation mode provided by the utility model, the rotating shaft is connected to the triangular bracket through a spherical roller bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0015] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0016] Reference Figure 1 The combined walking mechanism of the stacker provided in this embodiment comprises: a frame body composed of two triangular brackets 7 arranged symmetrically on the left and right, the upper ends of the two triangular brackets 7 are connected by a rotating shaft 6, and a mounting shaft 4 is arranged on the rotating shaft 6, which is used to install the combined walking mechanism on the stacker body, and the rotating shaft 6 and the mounting shaft 4 form a "cross" structure; the front and rear ends of the frame body are both provided with walking wheels 1; the frame body is also provided with guide wheels 2 and anti-tilt wheels 3. The frame body is an isosceles triangle structure, and the rotating shaft is arranged at the vertex.

[0017] The combined walking mechanism of the stacker provided in this embodiment has the following beneficial effects: 1. There are walking wheels 1 at both the front and rear ends of the frame, which increases the number of walking wheels 1, reduces the wheel pressure of a single wheel, thereby reducing the diameter of the walking wheel 1 and lowering the chassis height; 2. Through the rotatable frame, the wheels are evenly stressed, ensuring the stability of walking and avoiding overload of the walking wheel 1; 3. The walking wheel 1, anti-tipping wheel 3 and guide wheel 2 are all integrated on the frame, with a compact structure, which improves space utilization, reduces the chassis height, and is easy to disassemble and assemble, and convenient for maintenance.

[0018] Specifically, two running wheels 1 are provided at the front and rear ends of the frame. Four running wheels 1 can further reduce the wheel pressure of a single wheel and reduce the diameter of the running wheel 1.

[0019] There are two guide wheels 2 and two anti-tipping wheels 3 which are symmetrically arranged on the left and right.

[0020] Furthermore, the rotating shaft 6 is connected to the triangular bracket through the spherical roller bearing 5. The spherical roller bearing 5 is composed of an outer ring with a spherical raceway, an inner ring with double raceways, one or two cages and a group of spherical rollers. Since the center of the spherical raceway of the outer ring is consistent with the center of the bearing, it has a self-aligning performance, can automatically adjust the tilt or shaft deflection caused by the angle error between the shaft and the bearing seat, and can withstand large radial loads and bidirectional axial loads.

[0021] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
