Abstract

The invention discloses a force measuring device for the excavation force of an excavator and a test device using the force measuring device. The force measuring device comprises a left guard board, an installation support, a right guard board, a first tension and pressure sensor, a pedestal, a second tension and pressure sensor and proximity sensors; a pinhole of the installation support, an upper pinhole of the first tension and pressure sensor and an upper pinhole of the second tension and pressure sensor are installed together via a first cylindrical pin; the lower portion of the first tension and pressure sensor and the lower portion of the second tension and pressure sensor are hinged to the pedestal; the left and right guard boards are correspondingly mounted in the two sides of the top surface of the pedestal, and the two ends of the first cylindrical penetrate a pinhole of the left guard board and a pinhole of the right guard board respectively; and the proximity sensors are mounted in the outer side surfaces of the left and right guard boards respectively. The force measuring device is characterized by low installation difficulty, high test efficiency, low requirement for test place and low labor intensity.

Description

technical field [0001] The invention relates to a digging force measuring device of an excavator, which belongs to the technical field of hydraulic excavator tests. Background technique [0002] The excavator is the main tool for earthwork operations, and the excavator's digging force is one of the main performances of the excavator. In the design process, the size of the excavation force is also the main basis for the design and strength calculation of the working device. Usually, during the excavator excavation force test, the excavator bucket is used to pull the tension sensor to test the excavation force. In addition to the tension sensor, wire ropes, shackles, and ground anchors are also required on the test site. With the increase of vehicle tonnage, the length and tensile strength of the wire rope gradually increase, the strength of the shackle also gradually increases, the weight of the wire rope and the shackle also increases, and the installation difficulty and la...
