Description

Technical Field

[0001] The utility model relates to the technical field of processing accessories of excavators and loaders, in particular to an oil tank assembly structure of an excavator and loader. Background Art

[0002] An excavator loader is a single device composed of three pieces of construction equipment, commonly known as a "two-end busy" machine. During construction, the operator can change the working end by simply turning the seat. The core structure of the excavator loader is the powertrain. The powertrain design of the excavator loader can run freely on various rugged terrains.

[0003] For example, a fuel tank assembly structure for an excavator loader with the authorization announcement number "CN220483085U" is a structure in which the fuel tank body and the battery box are assembled together, and a first pedal body and a second pedal body are installed on the battery box. The ladder-shaped assembly structure effectively and reasonably utilizes the space used on the frame of the excavator loader, making it convenient for the staff to enter the cab; at the same time, the overall assembly structure fits tightly with the frame and the cab, which not only ensures the internal space but also reduces the space occupied by the outside and is more convenient for maintenance. However, when installing the fuel tank body, the operator of the excavator loader fuel tank assembly structure needs to hold the fuel tank body with one hand, so that the operator needs to consume more physical strength to install the fuel tank body, thereby increasing the manual labor. At the same time, since the excavator loader fuel tank assembly structure does not have a shock-absorbing structure, it usually generates vibration when the excavator loader is working. The bolts are easily loosened at the parts installed by bolts, making the parts unstable and damaged, and the operator needs to perform frequent maintenance, thereby reducing the service life. Utility Model Content

[0004] The utility model aims to solve the problem that when installing the fuel tank body, the operator needs to hold the fuel tank body with one hand all the time, so that the operator needs to consume more physical strength to install the fuel tank body, thereby increasing the manual labor.

A fuel tank assembly structure for an excavator loader is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0027] Working principle:

[0028] When it is necessary to install the fuel tank assembly structure of the backhoe loader:

[0029] Preparation process:

[0030] First, fix the fuel tank body 5 and the battery box 4 to the base plate 1 by bolts, then fix the second pedal 3 to the battery box 4 by bolts, and fix the first pedal 2 to the base plate 1 by bolts. The first pedal 2 and the second pedal 3 make it more convenient for the operator to operate the cab.

[0031] Fuel tank body installation process:

[0032] During the first installation, the support plate 602 and the clamping plate 603 are respectively inserted along the corresponding sliding grooves and protruding parts on the backhoe loader, so that the surface of the fixing plate 601 fits the surface of the backhoe loader. Then the operator pushes the fuel tank body 5 to make the limiting groove 604 slide along the protruding part of the backhoe loader surface corresponding to the limiting groove 604. When the fuel tank body 5 moves to the appropriate position, the pushing of the fuel tank body 5 is stopped. Then the operator fixes the fixing plate 601 through the bolts and the through holes processed on the fixing plate 601, so that when installing the fuel tank, the operator does not need to hold the fuel tank body with his hands all the time.

[0033] Installation process of shock absorbing mechanism:

[0034] First, the pad 905 is fixed to the surface of the excavator loader through the bolts and the through holes processed on the pad 905, and then the valve on the air intake pipe 904 is opened, and a proper amount of gas is injected into the sleeve 903 through the air intake pipe 904, and then the valve on the air intake pipe 904 is closed to make the sleeve 903 have a certain air pressure. When the excavator loader is working, vibration is generated, and the limit block 906 is driven by the telescopic rod 902 to slide along the inner wall of the sleeve 903, which plays a shock-absorbing role, so as to reduce the loosening of the bolts and the damage of the components, and the operator does not need to perform frequent maintenance, thereby increasing the service life.
