What is a construction machinery connecting rod?

The connecting rod of construction machinery is a common part of construction machinery, which plays an important role in connecting transmission and rotation in construction machinery equipment. This paper will introduce the definition, function, classification and application field of construction machinery connecting rod in detail.

Definition
Construction machinery connecting rod refers to a mechanical part that connects various components in construction machinery equipment, which is mainly fixed between two or more components by means of articulating or connecting pins. It is made of high-strength material, has excellent strength and wear resistance, and can withstand high loads and complex working conditions of construction machinery and equipment.

Feature

1. Connection transmission: Construction machinery connecting rod by connecting the drive shaft and driven shaft, to achieve the power transmission and rotation movement in the transmission system. It can make the various components of the construction machinery and equipment coordinate the movement and efficiently complete the work task.
2. Rotation support: The connecting rod as a connecting element can provide stable support during the movement of construction machinery and equipment. It reduces friction and dynamic load during rotation through a reasonable connection mode, making the equipment run more stable and reliable.
3. Adjustment position: the length and shape design of the connecting rod can be adjusted according to actual needs to adapt to different work scenes and workpiece sizes. By changing the connecting position of the connecting rod, the movement trajectory and working range of the construction machinery equipment can be flexibly adjusted.

Sort
According to the shape and characteristics, construction machinery connecting rod can be divided into the following types:

1. Rocker arm connecting rod: It has a hyperbolic shape and is commonly used in excavators, loaders and other equipment for rotating working parts such as digging buckets or loading buckets.
2. Transmission connecting rod: The linear shape is mainly used for parallel and cross-connection in the transmission system, such as the crankshaft connecting rod of the automobile engine and the working connecting rod of the bulldozer knife edge.
3. Locking connecting rod: It has a fixed function, which is used to keep the relative position of the two parts unchanged, such as the tipping bucket locking connecting rod of the dump truck.

Application field
Construction machinery connecting rod is widely used in various fields of construction machinery equipment, including but not limited to the following aspects:

1. Construction engineering: In excavators, loaders, bulldozers and other equipment, connecting rods are used to connect digging buckets, loading buckets, dodging knives and other working parts to achieve the operation of land and buildings.
2. Agricultural machinery: agricultural tractors, harvesters and other agricultural machinery and equipment, connecting rods are used to connect farming parts, harvesting knives, etc., to complete the planting and harvesting of crops.
3. Mining industry: In mining operations such as mining and tunnel engineering, connecting rods are used to connect digging buckets, drills and other working parts to provide strong and stable mining capabilities.
4. Port loading and unloading: In port cranes, dump trucks and other equipment, the connecting rod is used to connect the lifting arm and lifting spindles to realize the loading and unloading operation of goods.

In summary, the connecting rod of construction machinery, as an important connecting part, plays an important role in construction machinery and equipment. It realizes the coordinated movement of construction machinery and equipment and the completion of work tasks by connecting transmission, rotating support and adjusting position. Different types and shapes of connecting rods are widely used in various fields, promoting the development and progress of the construction machinery industry.
