Embodiment Construction
[0017] A kind of column jack external loading test bench, such as figure 1 As shown, it includes a terminal base 1 and two opposite columns 2 vertically installed and fixed on the two ends of the side wall of the terminal base 1. One end of the two columns 2 is connected and fixed through a connecting plate 3; A loading oil cylinder 4 is vertically fixed, and the loading oil cylinder 4 is located between two columns 2. Two clamping mechanisms 5 are clamped and installed between one ends of the two columns 2, and a sliding mechanism is installed between the other ends of the two columns 2. Movable beam 6, the bottom end of the column jack to be tested is installed and fixed on the movable beam 6, and the top is installed and connected with the power end of the loading cylinder 4;
[0018] Such as figure 2 , image 3 and Figure 4 As shown, the outer surfaces of the top side walls of the two columns 2 are fixed with racks 21, and the movable beam 6 includes a support fixed p...

The invention discloses the external loading test bench of a stand column and jack. The test bench comprises a terminal base, and two stand columns which are arranged oppositely and are vertically installed to the two side walls of the terminal base. One ends of the stand columns are fixed by a connection plate. The central section of one end surface of the terminal base is vertically fixed with aloading oil cylinder. Two clamping mechanisms are clamped between one ends of the stand columns. A movable beam is slidably installed between the other ends. The bottom end of the stand column and jack to be tested is installed and fixed to the movable beam, and the top end is connected to the power end of the loading oil cylinder. The test bench also comprises a loading device and a hydraulic test bench connected to the loading device. The hydraulic test bench is connected to a computer. Through connecting the hydraulic test bench and the computer, data recording, digital display, interactive curve drawing, print analysis and the like can be performed on the whole process of the test, and a test report can be automatically formed so that the work content of a user is reduced to a great extent and test efficiency is increased.
Description
technical field [0001] The invention belongs to the field of column jacks and relates to an external loading test bench for column jacks. Background technique [0002] The column jack external loading test bench is mainly used for the factory performance test and some type tests of the hydraulic support column and jack. Through the loading cylinder on the test stand, the factory test of the column and jack of "large resistance, large cylinder diameter, and large stroke" can be carried out, and the column, jack no-load stroke test, minimum starting pressure test, column, jack loading test, and guide sleeve sealing can be completed. Performance test and column, jack durability test. The column loading test bench currently on the market uses 4 sets of loading cylinders to perform loading tests on the column and the jack, which requires high machining accuracy, complicated assembly, and relatively high cost. Contents of the invention [0003] The purpose of the present inven...
