Description

Technical Field

[0001] This utility model relates to a bucket support lifting device, belonging to the field of aerial work platforms. Background Technology

[0002] When working, the aerial work platform needs to lift the work bucket to the working position using the working arm, and the workers work inside the work bucket. When there is a deviation between the work bucket and the working position, the height of the work bucket can be finely adjusted to facilitate the workers' work. The existing work bucket uses a slider structure for the bucket support lifting device during lifting. The slider has high frictional resistance, and the bucket support lifting process is characterized by shaking, abnormal noise and instability. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a bucket support lifting device with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the bucket support lifting device includes a fixed support and a lifting support. The lifting support is slidably installed on the fixed support. Its structural features are: it also includes a roller support, a roller pin, a contact roller, a limiting groove and a limiting frame. The limiting frame is set on the fixed support, the limiting groove is set on the lifting support, the contact roller is rotatably installed on the roller support through the roller pin, and the roller pin is slidably installed on the limiting frame. The contact roller is in contact with the wall of the limiting groove.

[0005] Furthermore, the fixed bracket is installed on the working arm of the aerial work vehicle, and the working bucket of the aerial work vehicle is installed on the lifting bracket.

[0006] Furthermore, the lifting bracket is driven by a lifting cylinder to move up and down on the fixed bracket.

[0007] Furthermore, an adjusting bolt is installed on the fixed bracket, and the adjusting bolt abuts against the roller bracket.

[0008] Furthermore, a limiting roller is installed on the fixed bracket, and the limiting roller contacts the wall of the limiting groove.

[0009] Furthermore, the axis of the limiting roller is perpendicular to the axis of the contact roller.

[0010] Compared with the prior art, the present invention has the following advantages: the lifting device of the bucket support can make the contact roller contact the wall of the limiting groove by turning the adjusting bolt, so as to change the surface contact to line contact, which can reduce the frictional resistance of the lifting support during lifting and thus ensure the smooth lifting and lowering of the lifting support.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example

[0022] See Figures 1 to 8As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0023] The bucket support lifting device in this embodiment includes a fixed support 1, a lifting support 2, a roller support 4, a roller pin 5, a contact roller 6, a limiting groove 9, and a limiting frame 10. The fixed support 1 is installed on the working arm of the aerial work vehicle, and the working bucket of the aerial work vehicle is installed on the lifting support 2.

[0024] In this embodiment, the lifting bracket 2 is slidably mounted on the fixed bracket 1. The lifting bracket 2 is usually driven by the lifting cylinder 8 to move up and down on the fixed bracket 1. The limiting frame 10 is set on the fixed bracket 1, the limiting groove 9 is set on the lifting bracket 2, and the contact roller 6 is rotatably mounted on the roller bracket 4 through the roller pin 5. The roller pin 5 is slidably mounted on the limiting frame 10, and the contact roller 6 is in contact with the wall surface of the limiting groove 9.

[0025] In this embodiment, the fixed bracket 1 is equipped with an adjusting bolt 3 and a limiting roller 7. The adjusting bolt 3 abuts against the roller bracket 4, and the limiting roller 7 contacts the wall of the limiting groove 9. The axis of the limiting roller 7 is perpendicular to the axis of the contact roller 6.

[0026] Specifically, when in use, the bucket support lifting device can drive the lifting support 2 on the fixed support 1 through the lifting cylinder 8 to achieve the lifting and adjustment of the working bucket. By turning the adjusting bolt 3, the roller support 4 can move within the limiting frame 10. Rotating the adjusting bolt 3 can adjust the entry and exit of the roller support 4, thereby adjusting the gap X between the contact roller 6 and the wall of the limiting groove 9. In other words, the roller pin 5 can slide within the limiting frame 10, thereby allowing the contact roller 6 to contact the wall of the limiting groove 9, which can reduce the friction between the lifting support 2 and the fixed support 1.

[0027] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model are included within the protection scope of this utility model.
