Description

Pressure testing equipment for straight-stroke cylinder Technical Field The utility model relates to the technical field of cylinders, in particular to pressure testing equipment for a straight-stroke cylinder. Background The straight travel cylinder refers to a cylinder with a piston doing linear reciprocating motion, and the output motion mode of the straight travel cylinder is linear motion along the axial direction of the cylinder, so that the straight travel cylinder can be used for gate valves and stop valves in many places in life. The pressure of the straight stroke cylinder is usually tested before the straight stroke cylinder is used, the piston rod of the straight stroke cylinder stretches in the pressure test process, and if the quality of the cylinder is problematic, the piston rod can be sprayed out, so that the straight stroke cylinder is very dangerous. Disclosure of utility model In summary, in order to overcome the defects of the prior art, the utility model provides safer pressure testing equipment for a straight travel cylinder. In order to achieve the above purpose, the utility model provides the technical scheme that the pressure testing device for the straight-stroke cylinder comprises a supporting seat, two clamping mechanisms and a protective cover, wherein the two clamping mechanisms are respectively arranged on two sides of the supporting seat in the width direction, each clamping mechanism comprises a first telescopic machine and a first push plate, the first telescopic machine controls the first push plate to move towards the direction of the supporting seat, the protective cover is positioned on one side of the supporting seat in the length direction, and a protective top cover is arranged at the position, above the supporting seat, of the protective cover. So set up, put the cylinder on the supporting seat during the use, then place the air inlet and the gas outlet of cylinder up, the first push pedal of the first telescopic machanism of reconcontrol promotes presss from both sides tight stable cylinder from both sides, afterwards can connect the trachea and carry out the pressure testing to the cylinder, the piston rod of cylinder just can be at the protection casing internalization when the pressure testing, the piston rod just can pop out in the protection casing when the cylinder has quality problems to lead to cylinder piston rod spun, hit the inner wall of protection casing, and the top of protection casing also is provided with the protection top cap, even rebound also can not pop out from the top, can not bullet tester, it is safer. Further, the clamping mechanism further comprises a second telescopic machine and a second push plate, the second telescopic machine and the second push plate are located on one side, opposite to the protective cover, of the supporting seat, the second telescopic machine controls the second push plate to move towards the protective cover, and a baffle is arranged on one side, facing the protective cover, of the top surface of the supporting seat. So set up, the second telescopic machine will promote the afterbody of second push pedal follow cylinder with the cylinder top clip on the baffle of opposite side, more stable, and can carry out a location to the cylinder, make its telescopic link's position just be located the below of protection top cap, just so just need not to be when placing and deliberately aim at the position, the operation is more convenient. Further, two baffles are arranged, and a gap is arranged between the two baffles. So set up, two baffles are pushed down by the cylinder simultaneously from both sides, and the area is bigger, and is more stable, and exists the clearance between the two can provide flexible space for the piston rod, can not influence its flexible test. Further, the device also comprises a third telescopic machine, wherein the third telescopic machine is used for controlling and changing the distance between the first push plate and the top surface of the supporting seat. So set up, the relative distance between the first push pedal of third telescoping machine can change to the supporting seat, just so when placing not unidimensional cylinder alright make first push pedal press the suitable position of corresponding size cylinder to carry out the centre gripping to it, it is more stable, first telescoping machine below can set up base bed hedgehopping height. Further, an output shaft of the third telescopic machine is connected with the supporting seat. The height of the supporting seat can be changed along with the size of the air cylinder, so that the supporting seat is matched with the first push plate to change the position and is always close to the protective top cover, and the safety is improved. Further, a top plate is arranged on one side of the top surface of the first push plate, which is positioned at the top of the supporting seat. So set up, the roof can block the cylinder from the top, a
