Description

Technical Field

[0001] The utility model relates to the field of load cells, in particular to a combined load cell capable of protecting connecting oil pipes. Background Art

[0002] At present, the load cells on the market are all composed of different numbers of jacks connected in series or in parallel. During the self-balanced static load test of the load cell, when the load cell is opened, a broken pile will inevitably be formed, and the position is between the upper and lower bearing plates of the load cell. The exact position is uncertain, but the oil pipes connecting the jacks and the main oil pipe are all within this range. During the test, the pile body is divided into upper and lower parts. The connecting oil pipe and the main oil pipe or their upper joints may pass through the cross-section, and may be pulled apart or broken when the displacement increases to a certain extent, resulting in leakage of the load cell and failing to achieve the test purpose.

[0003] During the installation process, some illegal construction units directly pour the concrete without passing through the diversion pipe. The stones and mortar in the concrete directly impact the oil pipe or the joint, which is not conducive to the sealing of the load cell. Content of the Utility Model
