Hydraulic breaking hammer performance measurement system

Abstract

The invention discloses a performance test system used in a hydraulic breaking hammer. The performance test system comprises a hydraulic breaking hammer fixing frame, a striking buffer device which is connected with the frame, a high-pressure hydraulic oil station which is connected with the detected hydraulic breaking hammer, an electric controlling table which is connected with the high-pressure hydraulic oil station, and a sampling and analyzing system which is used for collecting and processing the data of the detected hydraulic breaking hammer. A vertical testing device is used for testing the performance of the hydraulic breaking hammer, and simulating the working condition of the hydraulic breaking hammer, so as to acquire accurate testing results. The performance test system also prevents the cylinder of the testing device from poor lubrication as a result of excessively high pressure which is caused by the gravity of the piston, protects the piston and the cylinder from being pulled, and saves the space. In addition, the use of the pressure sensor to measure the impact of the hydraulic breaking hammer improves the accuracy of measurement. The data acquisition card and the work controlling table can be used for direct and clear on-line measurement, display and calculation of the impact of the hydraulic breaking hammer.

Description

technical field [0001] The invention relates to the field of performance testing of a hydraulic breaker, in particular to a performance test system of a hydraulic breaker. Background technique [0002] The hydraulic breaker is a kind of construction machinery widely used in the industrial and mining industry. Due to the quality and volume of the product, the performance detection of the hydraulic breaker has always been a difficult problem in the industry. Some companies install the product on the excavator for on-site inspection. However, there are many problems in transportation and installation. Some foreign manufacturers use the principle of resistance strain gauges to test the performance of hydraulic breakers. Due to the low sensitivity and poor accuracy of resistance strain gauges, they do not have the function of real-time measurement. In addition, they cannot measure the impact of the breaker. Peak, hydraulic oil flow, pressure, temperature and other data cannot be ...

[0002] The hydraulic breaker is a kind of construction machinery widely used in the industrial and mining industry. Due to the quality and volume of the product, the performance detection of the hydraulic breaker has always been a difficult problem in the industry. Some companies install the product on the excavator for on-site inspection. However, there are many problems in transportation and installation. Some foreign manufacturers use the principle of resistance strain gauges to test the performance of hydraulic breakers. Due to the low sensitivity and poor accuracy of resistance strain gauges, they do not have the function of real-time measurement. In addition, they cannot measure the impact of the breaker. Peak, hydraulic oil flow, pressure, temperature and other data cannot be recorded and analyzed

In addition, when testing multi-variety and multi-standard products, it is necessary to replace drill rods and resistance strain gauges of different diameters, which increases the cost and increases the difficulty of work.
