Abstract
A drawbar support device for large-size hydrostatic pressure tester is provided, which comprises a lower drawbar foundation, a frame that is composed of an upper drawbar and the lower drawbar and fixed to the foundation via a chassis, guide rails mounted on the lower drawbar, a movable carriage mounted on the guide rails, and a movable pressure test head mounted on one end of the movable carriage; the drawbar support device is characterized in: a support cylinder that is used to support the upper drawbar is fixed above both sides of the movable carriage frame.
Description
Technical field
The utility model belongs to steel pipe pressure checking device technical field,, particularly relate to a kind of large-scale hydrostatic test machine pull bar fulcrum arrangement.
Background technology
The heavy caliber thick wall seamless steel tube that is used for special trade at present, its maximum gauge of weldless steel tube that adopts as nuclear power station can reach 1200mm, thickest reaches 200mm, therefore the structure that is used to the hydrostatic test machine of pressure performance in the heavy caliber thick wall seamless steel tube that detects is also huge, because the stayed mast of four heavy in section box-structures that the hydrostatic test machine is fixedlyed connected with support is because of himself Heavy Weight (14070kg weighs), length long (length overall is 18900mm), span is big between two supporting-points, and middle no supporting-point, so the upper pulling force bar is subjected to conduct oneself with dignity and influences and produce amount of deflection.Because the difference of steel pipe scale, the mobile terminal pressure text head of hydrostatic test machine is easy to generate obstruction when mobile, the center line of the dowel hole on the upper pulling force bar is difficult to the assurance level simultaneously, this center line is two head heights, middle low camber line, when dowel hole on register pin and the stayed mast plugs, be difficult to centering, cause the plug difficulty.And along with the lengthening of service time, the amount of deflection of its stayed mast also strengthens thereupon, so bring inconvenience to operating personnel, work efficiency is affected.
Summary of the invention
The utility model provides a kind of design and reason and simple in structure, the large-scale hydrostatic test machine pull bar fulcrum arrangement of being convenient to operate for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Large-scale hydrostatic test machine pull bar fulcrum arrangement, comprise lower pulling force bar basis and be packed in the framework that constitutes by fixedly connected upper pulling force bar of frame and lower pulling force bar on this basis, on the lower pulling force bar, guide rail is housed, guide rail is provided with travelling car, one side of travelling car is connected with the mobile terminal pressure text head, it is characterized in that: the described travelling car vehicle frame left and right sides is fixed with the supporting oil cylinder that is used to support the upper pulling force bar near the top position.
Advantage and the good effect that the utlity model has are: since the utility model the travelling car left and right sides near above the position install supporting oil cylinder, after the mobile terminal of hydrostatic testing machine pressure text head moves to the relevant position along with travelling car, support cylinder is risen, make on the supporting oil cylinder piston rod plane contact and withstand upper pulling force bar bottom surface, offset the downwarp of upper pulling force bar, play support and share of the effect of upper pulling force bar from gravity; Register pin can be penetrated in the dowel hole smoothly, convenience is provided so not only for operating personnel's operation, also can increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, upper pulling force bar; 2, supporting oil cylinder; 3, mobile terminal pressure text head; 4, lower pulling force bar; 5, lower pulling force bar basis; 6, travelling car; 7, guide rail.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, large-scale hydrostatic test machine pull bar fulcrum arrangement, comprise lower pulling force bar basis 5 and be packed in the framework that constitutes by fixedly connected upper pulling force bar 1 of frame and lower pulling force bar 4 on this basis, guide rail 7 is housed on lower pulling force bar 4, guide rail 7 is provided with travelling car 6, one side of travelling car 6 is connected with mobile terminal pressure text head 3, in close top position, the vehicle frame left and right sides of described travelling car 6, promptly be useful on the supporting oil cylinder 2 that supports the upper pulling force bar near upper pulling force bar 1 position by bolt, a pair of supporting oil cylinder is established in every upper pulling force bar below.
Principle of work of the present utility model is:
Move to the position that needs scale when travelling car 6 drives mobile terminal pressure text head 3, two supporting oil cylinders 2 are bolted to connection the vehicle frame both sides of travelling car 6, and a pair of supporting oil cylinder is established in every upper pulling force bar below, establishes four supporting oil cylinders altogether.When wearing pin, because upper pulling force bar 1 downwarp, the dowel hole center line is descended, register pin can't penetrate in the dowel hole, at this moment start supporting oil cylinder, and by plane jack-up upper pulling force bar on the piston rod, power transmission is to lower pulling force bar basis again, downwarp is offset, just register pin can be penetrated in the dowel hole smoothly.Oil pressure in the supporting oil cylinder 2 needs to determine according to the weight of pull bar and the position of mobile terminal pressure text head 3.
When needing the steel pipe of batch testing same size, the invariant position of supporting oil cylinder during as if the steel pipe specifications vary, before the pressure text head of conversion mobile terminal, needs earlier the supporting oil cylinder piston rod is fallen, and after breaking away from the upper pulling force bar, shifts one's position again.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
