Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of excavators, and particularly relates to a fixing structure of a hydraulic pipe of a bucket assembly and an excavator. BACKGROUND

[0002] On a bucket assembly of an excavator, hydraulic pipes are usually provided, which are used to control the rotation of a bucket at the end of a dipper arm. However, in most cases, the hydraulic pipes are not properly fixed, resulting in a considerable free movement space of the hydraulic pipes. When the bucket is in a scooping operation, the hydraulic pipes will be clamped between a crank connecting rod and a dipper arm, as shown in the accompanying drawings. Such improper clamping will eventually cause the hydraulic pipes to be broken, thus causing unnecessary losses to the user. Figure 1 CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at solving the above-mentioned problems and provides a fixing structure of a hydraulic pipe of a bucket assembly and an excavator.

[0004] The technical solution of the present application is as follows:

[0005] In a first aspect, the present application provides a fixing structure of a hydraulic pipe of a bucket assembly, wherein the bucket assembly comprises a bucket and a dipper arm which are rotatable relative to each other, the hydraulic pipe is arranged along the dipper arm and one end of the hydraulic pipe is connected to the bucket, and the fixing structure is installed on the dipper arm.

[0006] The fixing structure is used to keep a predetermined part of the hydraulic pipe in position, so that a reserved section is formed between the predetermined part and the bucket.

[0007] The fixing structure comprises a first mounting block and a second mounting block which are detachable relative to each other, wherein the first mounting block is connected to the dipper arm.

[0008] The first mounting block and the second mounting block are both provided with mounting grooves at the parts close to each other, and when the first mounting block and the second mounting block are fixed relative to each other, two mounting grooves form a complete fixing groove, and the fixing groove is equivalent to the cross section of the hydraulic pipe.

[0009] The predetermined part is a part of the hydraulic pipe corresponding to the fixing structure

[0010] The above-mentioned technical solution has at least the following advantages or beneficial effects:

[0011] In a second aspect, the present application further provides an excavator, wherein a fixing structure of a hydraulic pipe of a bucket assembly as described above is installed on the bucket assembly of the excavator.

[0012] ​The advantages or beneficial consequences of the above technical solutions at least include:

[0013] By means of the fixing structure, the hydraulic oil pipe is fixed in place, and a certain reserved section is intentionally left, so that the shovel can be smoothly turned during turning operation. In addition, the design can effectively limit the degree of bending of the hydraulic oil pipe, prevent it from being clamped between the crank connecting rod and the excavating arm due to excessive bending, and avoid possible damage. Such a design not only facilitates the smooth production and installation process, but also ensures the efficiency and safety of the excavator during operation. BRIEF DESCRIPTION OF DRAWINGS
