Embodiment 1

[0036] Such as Figure 1-4 The shown biaxial adjustable multi-standard automatic air blowing device includes an electric push rod, a joint and an upper clamp 15 and a lower clamp 16 connected to each other. The left end of the electric push rod 10 is threaded and fixed on the The upper surface of the lifting frame 6, the right end is fixed on the left end surface of the weldment formed by the lower clamp 16 and the slider 17 through the flange 14; the left end surface and the right end surface of the tail pin seat 8 are welded with symmetrically distributed stoppers 7, so There is a groove on the joint 13, which is positioned on the upper surface of the lower clamp 16 through the groove, and the upper clamp and the lower clamp are connected by screws; the left end of the joint 13 is connected to the rubber hose 9, and the right end is connected to the muffler cover 30; The slide block 17 has a wedge-shaped groove, and is assembled on the slide plate 22 with a wedge-shaped groo...

Embodiment 2

[0044] On the basis of Example 1, if the specification of the steel pipe is changed, in order to ensure the blowing effect and prevent the nozzle from colliding with the steel pipe, it is necessary to ensure that the centerline of the nozzle and the centerline of the left end face of the steel pipe are basically on the same horizontal line. At this time, insert the removal tool into the tool hole at the right end of the nozzle 18, remove and replace the sound-absorbing cover of the corresponding specification, and at the same time adjust the limit device 29, first loosen the two limit nuts on the upper and lower end surfaces of the base 1, After the lifting frame 6 is adjusted to a suitable position, first tighten the stop nut 24 on the upper end of the base 1 to fix the height of the lifting frame, then tighten the stop nut 24 on the lower end of the base 1 to fix the displacement of the lifting frame in the vertical direction.

Embodiment 3

[0046] On the basis of Embodiment 2, since the steel pipe 26 is placed obliquely on the V-shaped lifting bracket 27 and has different sizes, the moving distance of the electric push rod 10 needs to be adjusted according to the different sizes. At this time, by adjusting the position of the electromagnetic induction switch 12 on the right side of the electric push rod 10, the displacement of the electric push rod in the horizontal direction can be adjusted, so as to avoid the rigid collision between the muffler cover and the steel pipe, and the protection device operates normally.

Abstract

The invention relates to the technical field of subsequent pipe machining finishing lines of steel pipe manufacturing, and discloses a double-shaft adjustable multi-specification automatic blowing device which comprises an electric push rod, a connector, an upper clamp and a lower clamp, the upper clamp and the lower clamp are connected with each other, the left end of the electric push rod is fixed to the upper surface of a lifting frame, and the right end of the electric push rod is fixed to the left end face of a welding piece composed of the lower clamp and a sliding block; the joint is provided with a groove and is positioned on the upper surface of the lower hoop through the groove, the left end of the joint is connected with the rubber pipe, and the right end is connected with the silencing cover; the sliding block is assembled on a sliding plate which is fixedly connected to the lifting frame. A small rib plate as wide as the lifting frame is connected to the center of the lower end face of the lifting frame, limiting devices and positioning columns are symmetrically arranged on the two sides of the lifting frame, the positioning columns are connected with guide rods, and a whole formed by the lifting frame and the guide rods is assembled on a base. A guide sleeve is connected to the base, and the gland and the guide sleeve are in threaded connection to fix the shaft sleeve in the guide sleeve. The invention has the advantages of no low temperature influence, double-shaft adjustability, multi-specification use, convenience in disassembly and assembly and the like.

Description

technical field [0001] The invention relates to the technical field of subsequent pipe processing and finishing lines for steel pipe manufacturing, in particular to a biaxial adjustable multi-standard automatic air blowing device used in steel pipe air-water blowing equipment. Background technique [0002] With the continuous development of my country's oil and gas industry, the demand for oil pipes and casings is increasing year by year, and their quality requirements are becoming more and more stringent. After the hydrostatic test of the steel pipe, it is necessary to blow the steel pipe with air and water to blow away the emulsion and residue inside the steel pipe, so as to prepare for the subsequent steel pipe diameter and painting process. [0003] Existing air blowing devices generally use a hydraulic cylinder or an air cylinder as a power source to drive a rubber hose equipped with compressed air to move horizontally to blow air to the steel pipe. Due to the small si...
