Embodiment 1

[0034] see Figure 1 to Figure 4 As shown, this embodiment provides a guide sliding assembly, which is used to be arranged between the first part 111 and the second part 112 which slide relatively. The first part 111 is provided with an arc-shaped groove, and the second part 112 can The length direction of the arc-shaped groove reciprocates. The guide slide assembly includes a base 101. The base 101 is used to be fixedly connected with the second part 112. The base 101 has an arc surface suitable for the arc-shaped groove. A ball 105, the ball 105 is used to contact the inner surface of the arc groove.

[0035] Based on this structure, the guide slide assembly provided in this embodiment can be installed in a component with an arc-shaped groove. When in use, the base 101 is fixedly connected to the second part 112. Since the base 101 has an arc surface suitable for the arc groove, and a plurality of balls 105 are arranged on the arc surface, when the first part 111 and the se...

Embodiment 2

[0058] see Figure 5 As shown, this embodiment provides a telescopic boom, including the first boom section 109, the second boom section 110 and the guide slide assembly provided in Embodiment 1 of the present invention, the first boom section 109 is sleeved on the second boom section 110 , an arc-shaped groove is provided on the inner surface of the first arm section 109 , the second arm section 110 can reciprocate along the length direction of the arc-shaped groove, and the base 101 is fixedly connected to the outer surface of the second arm section 110 .

[0059] In the telescopic jib provided in this embodiment, the inner surface of the first arm section 109 is provided with arc-shaped grooves. Using the guide slide assembly provided in Embodiment 1 of the present invention can form rolling friction between curved surfaces, improving the performance of arc-shaped grooves. The telescopic performance of the telescopic boom.

[0060] It should be noted that this embodiment p...

Abstract

The invention relates to the technical field of engineering machinery equipment, in particular to a guiding sliding assembly, a telescopic arm support and engineering machinery. The guiding sliding assembly is arranged between a first component and a second component which slide relative to each other; an arc-shaped groove is formed in the first component; the second component can reciprocate in the length direction of the arc-shaped groove; the guiding sliding assembly comprises a base; the base is fixedly connected with the second component; the base has the arc-shaped surface matched with the arc-shaped groove; and multiple balls are arranged on the arc-shaped surface and make contact with the inner surface of the arc-shaped groove. The guiding sliding assembly can be mounted in the component comprising the arc-shaped groove.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a guide sliding assembly, a telescopic arm frame and construction machinery. Background technique [0002] Guide sliding components are widely used between two parts that need to slide relative to each other to reduce frictional resistance. For example, in a large-scale construction machine with a telescopic boom, the guide sliding assembly is arranged between two adjacent boom sections that require relative telescopic movement to reduce wear, ensure smooth telescopic expansion, and play a certain supporting role. [0003] At present, most of the guide sliding components used between two adjacent boom sections of the telescopic boom on the crane are rollers arranged in the shell. This form is only suitable for the contact between planes, that is, the two adjacent It can be used when the shape of the cross-section of the section is rectangular. If the arm...
