As shown in fig. 1, rotating shafts are respectively erected at the front end and the rear end of the upper end face of the cantilever beam through a fixed mounting seat 2 and a swinging mounting seat 4, and chain wheels are arranged on the rotating shafts at the two ends; as shown in fig. 2 and 4, the sprocket is a double-toothed sprocket, a track assembly is meshed and wound on the two double-toothed sprockets, the track assembly comprises a double-row track 18 and a track hub 12, the double-row track is meshed on the double-toothed sprocket, two circles of track hubs are arranged on the outer ring of the double-row track at intervals through a hub fixing carrier plate 19, and a photoelectric encoder is connected on one side of the sprocket through a connecting piece and is used for measuring the linear walking speed of a steel pipe.
As shown in fig. 2, the fixed mounting seat comprises a fixed seat 8 and a bearing seat 7, the fixed seat is symmetrically arranged at the left side and the right side of the rear end track assembly of the cantilever beam, the fixed seat is a channel steel which is arranged vertically, the lower groove wall of the channel steel is connected to the cantilever beam, and the bearing seat for erecting a rotating shaft is arranged on the upper groove wall of the channel steel.

The invention aims to solve the problems that:
1. In the spiral advancing process of the steel pipe, a linear traveling speed component and a spiral speed component are generated, so that the spiral speed component is counteracted when the real-time linear traveling speed of the steel pipe is measured;
2. The steel pipe body is not an absolute flat structure, i.e. the section of the steel pipe is not an absolute circular structure, and the steel pipe has an ovality problem, so that the steel pipe can jump up and down in the spiral advancing process.
Aiming at the problem 1, the invention is realized by the double rows of crawler belts and the crawler wheel hubs arranged on the double rows of crawler belts, the crawler wheel hubs on each row of crawler belts are arranged in parallel, and the steel pipes are arranged on the tangential lines of the outer edges of the two rows of crawler wheel hubs (as shown in figure 1), so that the technical scheme can offset the rotation speed component of the steel pipes during spiral conveying;

The invention adopts a double-row crawler belt mode to measure the linear speed of the spiral conveying steel pipe in real time, and in order to avoid the problem that the double-row crawler belt influences the measuring precision due to the reduction of the tensioning force under the condition of long-term use, the swinging mounting seat can also play a role in self-adjusting the tensioning force. That is, after the steel pipe is pressed on the double-row track, the installation table of the swing installation seat is lifted by the gravity of the steel pipe, and the double-row track is tensioned, so that the double-row track is in a relatively straight state.
