A lightweight excavator underframe

Abstract

This utility model provides a lightweight excavator underframe, belonging to the technical field of excavator underframes. It includes a frame body and a top fixing head. The top fixing head is fixedly connected to the top of the frame body, a first connecting head is fixedly connected to the front of the frame body, and a second connecting head is fixedly connected to the back of the frame body. This utility model adds a wear-resistant layer, active electrodes, and connecting wires to the frame body. The wear-resistant layer is made of hard plastic. When the bottom of the frame body comes into contact with the ground, wear occurs preferentially, slowing down the paint peeling rate. The active electrodes preferentially undergo an oxidation reaction, generating electrons, which are then transported to the interior of the connecting wires. The connecting wires then transport electrons to the interior of the frame body, thereby replenishing the entire frame body with electrons, slowing down the corrosion rate and extending the service life of the excavator underframe.

Description

Technical Field

[0001] This utility model belongs to the technical field of excavator underframes, and particularly relates to a lightweight excavator underframe. Background Technology

[0002] The excavator seat is a commonly used modern construction machine. During its production and assembly, the excavator underframe is often used to provide fixing points for the excavator's transmission components and to support the excavator's cab. However, existing excavator underframes lack corrosion-delaying components, which cannot slow down the rate of paint cracking or corrosion during the use of the excavator underframe. Utility Model Content

[0003] To achieve the above objectives, the present invention adopts the following technical solution:

[0004] A lightweight excavator underframe includes a frame body and a top fixing head, characterized in that the top fixing head is fixedly connected to the top of the frame body, a first connecting head is fixedly connected to the front of the frame body, and a second connecting head is fixedly connected to the back of the frame body.

[0005] Preferably, a first damping layer is arranged inside the first connector.

[0006] Preferably, a second damping layer is arranged inside the second connector.

[0007] Preferably, a wear-resistant layer is fixedly connected to the bottom of the vehicle frame.

[0008] Preferably, a fixing seat is fixedly connected to the inner side of the vehicle frame, and an active electrode is fixedly connected to the top of the fixing seat.

[0009] Preferably, a connecting wire is fixedly connected to the outer surface of the active electrode, and the tail end of the connecting wire is connected to the inner side of the vehicle frame.

[0010] Preferably, a pull handle is fixedly connected to the top of the frame body, the pull handle is located outside the top fixed head, and four pull handles are provided.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention adds a wear-resistant layer, an active electrode, and connecting wires. The wear-resistant layer is made of hard plastic. When the bottom of the chassis comes into contact with the ground, wear occurs preferentially, slowing down the paint peeling rate. The active electrode preferentially undergoes an oxidation reaction to generate electrons, which are then transported to the interior of the connecting wires. The connecting wires then transport the electrons to the interior of the chassis, thereby replenishing the entire chassis with electrons, slowing down the corrosion rate and service life of the excavator's lower chassis.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1-4A lightweight excavator underframe includes a frame body 1 and a top fixing head 2. The top fixing head 2 is fixedly connected to the top of the frame body 1. The frame body 1 provides fixing points for the top fixing head 2, a first connecting head 3, a second connecting head 4, a wear-resistant layer 7, a fixing seat 8, and a pull handle 11, which are fixedly connected to its outer surface. The top fixing head 2 is fixedly connected to the top of the frame body 1 and connected to the bottom of the external cab, providing support for the external cab. The first connecting head 3 is fixedly connected to the front of the frame body 1. Connected to an external transmission, the excavator's mobility is ensured after assembly. A second connector 4 is fixedly connected to the back of the frame body 1, and the second connector 4 is fixedly connected to the back of the frame body 1, connecting to the driven parts of the external excavator for subsequent operation. A pull handle 11 is fixedly connected to the top of the frame body 1, providing a point of leverage for the user to move the frame body 1 as a whole. The pull handle 11 is located outside the top fixed head 2, and four pull handles 11 are provided.

[0020] Reference Figures 1-4 The first connector 3 has a first damping layer 5 inside, which is made of liquid epoxy resin. When an impact force is applied to the first connector 3, the impact force is absorbed by the good damping properties of the liquid epoxy resin. The second connector 4 has a second damping layer 6 inside, which is also made of liquid epoxy resin. When an impact force is applied to the second connector 4, the impact force is absorbed by the good damping properties of the liquid epoxy resin, thus improving the structural strength of the frame body 1. A wear-resistant layer 7 is fixedly connected to the bottom of the frame body 1. The wear-resistant layer 7 is made of hard plastic and is fixedly connected to the bottom of the frame body 1. When the bottom of the frame body 1 comes into contact with the external ground, wear occurs preferentially, slowing down the rate of paint peeling. A fixing seat 8 is fixedly connected to the inner side of the frame body 1. The fixing seat 8 is made of rubber and is used for fixing... The active electrode 9 is fixed to the top of the frame body 1 and connected to the inner side of the frame body 1, providing a fixing point to prevent the active electrode 9 from directly contacting the frame body 1. The active electrode 9 is fixedly connected to the top of the fixing seat 8 and is made of a metal with a high metal activity series. When the moisture in the external environment is conducted to the inner side of the frame body 1, the active electrode 9 preferentially undergoes an oxidation reaction to generate electrons and transports the electrons to the inside of the connecting wire 10. The connecting wire 10 is fixedly connected to the outer surface of the active electrode 9. When electrons are transported to the inside of the connecting wire 10 through the active electrode 9, the connecting wire 10 transports the electrons to the inside of the frame body 1, thereby replenishing the entire frame body 1 with electrons, slowing down the corrosion rate and service life of the excavator's lower frame, and the tail end of the connecting wire 10 is connected to the inner side of the frame body 1.

[0021] The functional principle of this utility model can be explained through the following operation: First, the first connector 3 is connected to the external transmission by external force, and the second connector 4 is connected to the external driven component to complete the fixation of the bottom of the frame body 1. Then, the cab is fixed to the top of the frame body 1 by the top fixing head 2, thereby completing the installation and construction of the excavator underframe. At the same time, when the bottom of the frame body 1 comes into contact with the external ground, wear occurs preferentially, which slows down the rate of paint peeling. The active electrode 9 preferentially undergoes an oxidation reaction to generate electrons, and the electrons are transported to the interior of the connecting wire 10. The connecting wire 10 transports electrons to the interior of the frame body 1, thereby replenishing the entire frame body 1 with electrons, slowing down the corrosion rate and service life of the excavator underframe.
