In the test process of high-power erecting electric cylinder, the electric cylinder test buffer trolley is mainly used to support the erecting platform and absorb the erecting platform when the erecting platform is abnormally powered off or the motor brake fails during the erecting and leveling process The impact energy generated by the falling of the vertical frame can prevent the equipment from being damaged by the stalling and falling of the vertical frame, and the impact energy generated by the falling of the vertical frame is very large. It plays the role of protective buffer. At the same time, when the buffer car absorbs the impact energy, the buffer car will retreat under the force of the horizontal direction, which not only affects the buffer effect, but also causes damage to personnel and equipment if the retreat speed is too high. , we need to design a kind of buffer car that can resist and remove the impact energy of the erection platform hitting the buffer car, and will not back off during the impact to affect the buffering effect

The invention discloses a buffer trolley for electric cylinder test. The main technical problem to be solved is how to design a buffer trolley capable of resisting and removing impact energy of a vertical frame impacting on the buffer trolley without affecting the buffer effect because the buffer trolley does not retreat during the impact. The buffer trolley for electric cylinder test comprises atrolley body, wherein the trolley body is provided with a detection unit for detecting whether the vertical frame falls off and a buffer assembly bearing the impact of the vertical frame; the lower part of the trolley body is provided with a retaining structure used for preventing the trolley body from retreating; the lower part of the trolley body is provided with an anti-derailing device for preventing the trolley body from derailing; and an action of the retaining device is controlled through receiving a signal transmitted from the detection unit by means of the controller. The technical scheme disclosed by the invention effectively solves the problem, and can be applied to the buffer trolley.
Description
technical field [0001] The invention relates to a buffer trolley for electric cylinder testing. Background technique [0002] The electric cylinder is a device that converts the rotary motion of the motor into a linear motion. It has the advantages of precisely controlling the position, speed and thrust, and is widely used in mechanical automation, industrial robots, automobiles and other fields. In the development and production process of electric cylinders, it is necessary to test various performance parameters of electric cylinders, such as maximum load, thrust, pull, stroke, etc. In the test process of high-power erecting electric cylinder, the electric cylinder test buffer trolley is mainly used to support the erecting platform and absorb the erecting platform when the erecting platform is abnormally powered off or the motor brake fails during the erecting and leveling process The impact energy generated by the falling of the vertical frame can prevent the equipment f...
