Abstract
The utility model belongs to the technical field of hydrostatic testing machines and tools, and especially relates to a pneumatic steel pipe hydrostatic testing machine. The utility model discloses a pneumatic steel pipe hydrostatic testing machine, comprising a base plate, a support disposed on the base plate, a cylinder disposed on the support, an upper clamp die connected with the cylinder, a lower clamp die disposed below the upper clamp die on the base plate, a shaft fixed below the base plate, shaft wheels disposed on two ends of the shaft, a plurality of L-shaped spacing plates disposed on sides of the base plate, side wheels disposed on the L-shaped spacing plates, a seal seat disposed on the base plate, a threaded rod disposed on the seal seat, and a sealplate disposed on an end of the threaded rod. The upper clamp die and the lower clamp die can cooperate and clamp with each other. After the upper clamp die and the lower clamp die are closed, the upper clamp die and the lower clamp die are disposed on a same axis with the sealplate. Positions of a whole hydrostatic testing machine can be conveniently and rapidly adjusted in a labor saving manner according to requirements of pipes in an actual test, so that tightness of the whole hydrostatic testing machine is more outstanding.
Description
Technical field
The utility model belongs to hydrostatic testing machine tool technical field, relates in particular to a kind of pneumatic steel pipe hydrostatic tester.
Background technology
Hydrostatic testing machine is exactly by water pump water filling in the steel pipe, makes that hydraulic pressure reaches test pressure in the steel pipe, and whether inspecting containers leaks.And the structure that is used for detecting the hydrostatic testing machine of usefulness in the present steel pipe enterprise generally comprises a location-plate, is provided with threaded rod at location-plate then, and an end of threaded rod is connected with seal.When in use the monoblock location-plate is fixed in the tank, fixes location-plate by the clamping plate of tank both sides, the turn threaded rod carries out the sealing to pipe then.This type of be more easy hydrostatic testing machine, can regulate the position of location-plate according to the length of pipe.Its defective is: the one, and, pipe need seal end shakiness in sealing, makes that easily sealing effectiveness is bad, thereby causes the failure of an experiment; The 2nd,, when needs are regulated location-plate, will move location-plate, and location-plate all is heavier, thus very inconvenient when regulating, cause and use inconvenience.
Summary of the invention
The purpose of this utility model is to solve above-described technical matters, and a kind of pneumatic steel pipe hydrostatic tester is provided, and its technical scheme is as follows:
A kind of pneumatic steel pipe hydrostatic tester comprises base plate, and described base plate is provided with support, described support is provided with cylinder, described cylinder is connected with upper clamp formwork, and the below place that is positioned at upper clamp formwork on the described base plate is provided with lower clamp formwork, the clamping that can match of described upper clamp formwork and lower clamp formwork; Axle is fixedly arranged at the bottom of described base plate, and the two ends of described axle are provided with arbor wheel; The sidepiece of described base plate is provided with some L shaped limiting plates, and described L shaped limiting plate is provided with side wheel; Described base plate is provided with sealing socket, and described sealing socket is provided with threaded rod, and an end of described threaded rod is provided with seal pad, arranges with the seal pad coaxial line after described upper clamp formwork and the lower clamp formwork closure.Optimal way is that described upper clamp formwork is provided with the guard collar that clamping is mutually mated with lower clamp formwork.
The pneumatic steel pipe hydrostatic tester that the utility model provides when in use, is adjusted the position of whole base plate earlier according to the length of pipe.The arbor wheel of general both sides of the present utility model is arranged on the tank, by L shaped limiting plate can so that whole base plate can be limited in can only the enterprising line slip of tank.Arbor wheel and side wheel all are to slide when sliding.So can adjust the position of base plate very easily according to the actual needs of pipe.After adjusting the position of base plate, pipe is placed on the lower clamp formwork, then by cylinder, makes upper clamp formwork press down, till upper clamp formwork and lower clamp formwork cooperate with tube grip.At this moment, can the hand rotation threaded rod, make seal pad to the nipped end motion of pipe, till seal pad is pipe sealing.Just can carry out the hydraulic testing this moment.
Arrange with the seal pad coaxial line after upper clamp formwork described in the utility model and the lower clamp formwork closure.When upper clamp formwork and lower clamp formwork clamped closed and seal pad be the coaxial line setting, like this can be so that pipe when being clamped, seal pad can be the coaxial line setting with pipe, makes the better tightness of seal pad in the sealed tube period of the day from 11 p.m. to 1 a.m.Make that seal pad stressed situation when the hydraulic testing is more even, can play the effect that prolongs its service time.
Be the U-shaped groove that is provided with mutual correspondence on upper clamp formwork of the present utility model and the lower clamp formwork, place pipe in the U-shaped groove and use, can be more steady so that pipe is placed.Described upper clamp formwork is provided with the guard collar that clamping is mutually mated with lower clamp formwork.And guard collar generally all is plastic material, can prevent that the outside surface of pipe from wearing and tearing owing to stressed.
The utility model has adopted the pneumatic clamping mode, has adopted the U-shaped sealing means, and making can maximum pressure-bearing: 20MPa.
The utility model can according to reality test pipe needs and very convenient, laborsaving, adjust the position of whole hydrostatic testing machine efficiently, make that the sealing of whole hydrostatic testing machine is more outstanding.
