Description

Technical Field

[0001] The utility model relates to the technical field of welding fixing devices, in particular to a welding fixing device for a counterweight mounting seat. Background Art

[0002] When installing equipment, in order to ensure the safe operation and production efficiency of the equipment, a series of meticulous preparations need to be carried out, including the installation of counterweights. Equipment installation counterweights refer to adding metal materials such as copper blocks and lead blocks to specific parts of the equipment to balance the weight distribution of the equipment and prevent the equipment from shaking or tipping over.

[0003] There are mainly the following functions: 1. Ensure the stability of the equipment. Equipment installation weight is an important measure to ensure the stability of the equipment. Through reasonable weight distribution, the impact of external forces on the equipment can be reduced and the equipment can be kept stable. 2. Improve the operating efficiency of the equipment. Equipment installation weight can reduce vibration and noise during equipment operation, reduce energy consumption, and improve the overall reliability and life of the equipment. 3. Reduce equipment damage and failure. Reasonable equipment installation weight can reduce equipment wear and failure, thereby reducing the cost of equipment maintenance and replacement.

[0004] The Chinese patent with the announcement number CN201920709243.0 currently discloses a welding fixing device for an excavator counterweight mounting seat. In the utility model, the horizontal length of the folding plate is changed by moving the movable plate forward and backward, thereby causing the center of gravity of the load-bearing block to shift. The load capacity of the digging claw is adjusted by the center of gravity shift of the load-bearing block and the formation of a lever, so that the load capacity of the digging claw can be adjusted while the load-bearing block can maintain the stability of the excavator body.
