Abstract
The utility model discloses a jack dynamic load tester, which comprises a chassis, a platen, a frame, a pull hook, a following oil cylinder, a top plate, a measuring device, a main oil cylinder and a pressure transmitter, wherein the main oil cylinder is installed on the frame which is fixed on the platen. The top plate is connected with a piston rod of the main oil cylinder, the measuring device is connected with the top plate and the following oil cylinder is arranged on the platen. The dynamic load tester of the utility model reduces the dimension of the appearance of the frame. The height between a working table and the ground surface is small, so operation is more convenient. In addition, the use performance of the utility model is safer.
Description
Technical field the utility model relates to a kind of lifting jack that is applicable to and makes the specialized equipment of dynamic load test, especially a kind of horizontal lifting jack dynamic test machine.
Background technology is present, the employed dynamic test machine of the horizontal lifting jack of domestic major part (being the garage lifting jack) manufacturing enterprise and national handling machinery quality supervision and test center all is the formula of heavily hanging down, and small business's direct jack-up weight of lifting jack hand-manipulated is especially done dynamic test.Formula dynamic test machine adopts mechanical principle to operate owing to heavily hang down, and its volume is bigger, and it is not too convenient to operate, and usability neither be fool proof reliable.
The summary of the invention technical problem to be solved in the utility model is to propose the lifting jack dynamic test machine that a kind of structure is less, easy to operate, usability is safe and reliable.
For solving the problems of the technologies described above, the utility model lifting jack dynamic test machine comprises chassis, platen, framework, drag hook, retinue oil cylinder, top board, determinator, master cylinder and pressure unit, described master cylinder is installed on the described framework, described frame fixation is on described platen, described top board is connected on the piston rod of described master cylinder, described determinator is connected on the described top board, and described retinue oil cylinder is arranged on the described platen.
Above-mentioned lifting jack dynamic test machine, described retinue oil cylinder comprises hydraulic cylinder assembly and pulley dolly, described hydraulic cylinder assembly is arranged on the described pulley dolly, drives jack handle by its linear reciprocating motion and swings up and down, to reach the purpose of jacking lifting jack; Described pulley dolly places in the guide plate of described platen rear end, and in lifting jack jacking process, it slides before and after following lifting jack by the connection of drag hook.
Above-mentioned lifting jack dynamic test machine, described determinator comprises metallic tape, elevation measurement device and slippage determinator, and described metallic tape is arranged on framework one side, and described elevation measurement device and slippage determinator are separately positioned on the both sides of described top board.
Above-mentioned lifting jack dynamic test machine, a side of described framework is provided with frid, and an end of described top board places in the frid and slides up and down.
The utility model is owing to adopted above-mentioned technical pattern, and it adopts hydraulic principle, and the mode that master cylinder adopts pair oil cylinders to work simultaneously presses to the dynamic test of horizontal lifting jack.The weight Chui Shi mechanism testing machine that compares, the physical dimension that the utility model dynamic test machine has dwindled framework greatly, worktable is highly also very low (having only 85mm) overhead, and is more convenient to operate, and its usability is safer reliable.
