Embodiment 1

[0046] A semi-automatic grinding and polishing device for natural gas pipelines, including a grinding chamber 1, a grinding assembly and a clutch assembly;

[0047] The front side of the grinding chamber 1 is provided with a sliding door 22, and the left side is provided with a rotating motor 2. The rotating motor 2 stretches out the driving shaft 3 to the right, and the driving shaft 3 stretches into the grinding chamber 1 and is fixedly connected with a left turntable 17; 1 The right side is correspondingly provided with a No. 2 cylinder 15, and the telescopic rod of the No. 2 cylinder 15 extends into the grinding chamber 1 to the left and is connected with a right turntable 16 for rotation;

[0048] The grinding assembly includes a screw mandrel 8, an electric telescopic rod 10 and a grinding sleeve 11. The screw mandrel 8 is arranged on the upper part of the grinding chamber 1. The right end of the screw mandrel 8 is connected to the inner wall of the grinding chamber 1 thr...

Embodiment 2

[0053] The difference from Embodiment 1 is that the grinding sleeve 11 is an arc-shaped piece, and the top surface is provided with a protrusion 24, and the protrusion 24 is provided with a through groove connecting the bottom surface, and the grinding plate 25 is inserted and passed through the through groove, and the protrusion 24 Correspondingly, a locking screw 26 is provided, and the locking screw 26 fixes the grinding plate 25 on the grinding sleeve 11, so that the grinding plate 25 is mounted on the grinding sleeve 11 in a detachable and adjustable manner, so that the grinding plate 25 can be efficiently utilized. It is also easy to replace.

Embodiment 3

[0055] The difference from Embodiment 2 is that the bottom of the grinding chamber 1 is evenly provided with a support 20, the support 20 includes an arc-shaped support plate, a hydraulic rod 28 and a roller 27, and the hydraulic rod 28 is fixedly installed on the bottom of the grinding chamber 1. The support plate is arranged on the top of the hydraulic rod 28, and the top surface of the curved support plate is symmetrically provided with rollers 27, so that when the pipeline 18 is placed, the pipeline 18 can be mounted on the support member 20 first, and the height can be adjusted to the same height as the hydraulic rod 28. The left and right turntables 16 are coaxial.

Abstract

The invention relates to the technical field of natural gas pipeline machining, in particular to a semi-automatic natural gas pipeline sanding and polishing device. A single motor is utilized for driving a lead screw to rotate through transmission, the motion characteristic of the lead screw is utilized for driving a sanding sleeve to move, by means of cooperation with an air cylinder, a pipelinecan be clamped in a rotating manner, and finally sanding and polishing of the pipeline are completed; a transmission assembly is provided with a clutch assembly composed of the air cylinder, a connecting rod and a clamping rod, by adjusting telescoping of the air cylinder, a conveying part corresponding to a conveying belt is changed, thus rotating and stopping of the lead screw are achieved, thenmoving and fixing of the position of the sanding sleeve are achieved by changing motion of a moving nut, and thus different sanding needs can be met; the inserting and fixing manner is adopted in thesanding plate, the sanding plate cooperates with an electric telescoping rod connected to the top, and thus applicability is wide; and a dust sucking opening is further formed, in the sanding process, flying dust in a sanding box can be sucked out, eliminated, and prevented from further overflowing, the production environment is improved, time waiting for dust settlement is also saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline processing, in particular to a semi-automatic grinding and polishing device for natural gas pipelines. Background technique [0002] Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. Natural gas pipeline transportation has the advantages of low transportation cost, small land occupation, fast construction, large oil and gas transportation volume, high safety performance, less transportation loss, no "three wastes" discharge, low risk of leakage, small environmental pollution, and little impact from harsh weather. The equipment maintenance is small, easy to manage, and easy to realize remote centralized monitoring and other advantages. [0003] During the production of natural gas pipel...
