Embodiment 1

[0061] like Figure 1-9 And shown in 12, the present invention provides a kind of hydraulic pressure testing machine that is used for super-large-diameter cast pipe fitting; The sealing tool is used for sealing, and the corresponding tooling is installed on the main cylinder, the cylinders on the left and right sides, and the platform of the trolley. After the mobile trolley carries the pressure test pipe fittings into the equipment, the main cylinder is moved downward and pressurized, and the pipe fittings are moved up and down by the tooling. Seal and press tightly. Then adjust the height of the center of the side cylinder by lifting the oil cylinder so that the center of the right (left) side cylinder is aligned with the center of the middle hole of the tee pipe fitting, then the side cylinder moves forward and pressurizes, and seals the middle hole of the pipe fitting through the radial sealing tooling of the socket and press tight. The right (left) side is in contact wi...

Embodiment 2

[0064] like Figure 10 , 11 Shown, (on the basis of embodiment 1,) the present invention also provides a kind of hydraulic pressure testing machine that is used for super large-diameter cast pipe fitting; Sealing, install the corresponding tooling on the left cylinder and the right cylinder respectively, install the adjustment square box and the corresponding elbow bracket on the trolley platform, adjust the center height of the elbow by adjusting the combination of the square box, and adjust the tilt of the side cylinder by rotating the oil cylinder Angle, lift the side cylinder drive mechanism to the top dead center through the lifting cylinder and hold it, then the side cylinder moves forward and pressurizes, and seals and compresses the two holes of the elbow pipe fitting through the socket radial sealing tool. The sealing needs of elbows of various specifications can be realized.

[0065] After the pipe fittings are sealed, water is injected into the pipe fittings throu...

Abstract

The invention relates to the technical field of the hydrostatic test device of the cast pipe, specifically hydrostatic testing equipment for an ultra-large drift diameter cast pipe, and relates to hydrostatic test devices in different structural forms and with drift diameters at DN1600-2200 pipe fitting. The hydrostatic testing equipment comprises a mounting support frame, a main cylinder, side cylinders, side cylinder driving mechanisms, a moving trolley and tools, wherein the mounting support frame is a hollow-square shaped frame structure; the main cylinder is arranged at a middle locationof an upper part of the mounting support frame; the side cylinder is arranged at a side cylinder driving mechanism; the side cylinder driving mechanism can move along an upright under the driving of alifting cylinder; the moving trolley is arranged at a lower part of the mounting support frame; a tee pipe fitting is arranged on the moving trolley and moved to the center of the mounting support frame; an upper part port of the tee pipe fitting is blocked by the tool on the main cylinder, the middle port is blocked by the tool on the side cylinder at the left side (or right side), and the otherside cylinder provides support force balance, and the lower part is blocked by the tool on the moving trolley.

Description

technical field [0001] The invention relates to the technical field of hydraulic test equipment for cast pipe fittings, in particular to hydraulic test equipment for cast pipe fittings with super-large diameters, and in particular to hydraulic test equipment for pipe fittings with diameters ranging from DN1600-2200 in different structural forms. Background technique [0002] The existing hydraulic testing machine can complete the compression test of cast pipes with a specific diameter specification (DN diameter < 1600mm). However, the fuselage frame of this type of elbow type hydraulic testing machine is a triangular inclined frame, and the position of the side cylinder is fixed, which cannot move up and down along the frame. It is only suitable for the elbow hydraulic test of specific specifications and fixed angles; The fuselage frame of the type hydraulic testing machine is a vertical frame, and the side cylinder driving mechanism can move up and down along the column,...
