Single-power telescopic manipulator for clamping concrete test piece

Abstract

The invention discloses a single-power telescopic manipulator for clamping a concrete test piece. The manipulator comprises a first vertical seat used for limiting a first knuckle arm, a second vertical seat used for limiting a second knuckle arm, a driving device used for driving the first knuckle arm to move, the first knuckle arm used for driving the second knuckle arm to move, the second knuckle arm, a transmission mechanism, a guide mechanism, a balance mechanism used for balancing the first knuckle arm and the second knuckle arm, and a clamping jaw assembly; and the driving device is connected with the first knuckle arm through the transmission mechanism, the first knuckle arm is fixedly connected with the second knuckle arm through the transmission mechanism, the first vertical seatis slidably connected with the first knuckle arm through the guide mechanism, the first vertical seat is fixedly connected with the second vertical seat through the balance mechanism, the second vertical seat is slidably connected with the second knuckle arm, and the clamping jaw assembly is installed on the second knuckle arm. The first knuckle arm and the second knuckle arm can move at the sametime, the speed of the second knuckle arm is higher than that of the first knuckle arm, the operation speed is high, the stroke is lengthened in a limited space, and the manipulator adapts to different laboratory heights.

Description

technical field [0001] The invention relates to a single-power telescopic manipulator used for clamping concrete specimens, and belongs to the technical field of concrete compression test equipment. Background technique [0002] Concrete is primarily subjected to pressure in structures, so its compressive strength index is the most important strength index. The compressive strength of concrete is related to many factors such as composition materials and construction methods, and is also affected by factors such as the size of the test piece, loading method, and loading speed. Therefore, there must be a standardized strength measurement method and corresponding strength evaluation specifications. [0003] At present, there are two kinds of concrete specimen shapes selected for determining the compressive strength of concrete in the world: cylinder and cube. According to the rules of our country, the compressive strength of concrete is measured by cube specimens, and it is us...

Problems solved by technology

[0004] At present, most quality inspection institutions still use manual handling of concrete specimens in the process of concrete compressive strength testing, moving the specimens from the material turnover trolley to the center of the press head, and waiting for the press to complete the compression test. After the strength test is over, the test block is moved to a trolley for transportation, which has the disadvantages of high labor intensity, low work efficiency and high cost
