Embodiment 1

[0030] Such as Figure 1-12 As shown, a telescopic transmission device includes a sprocket box 3 and a track trolley chain. The track trolley chain is composed of a plurality of track trolleys 2 hinged at the end, and two adjacent track trolleys 2 are connected by a movable hinge 5. The hinge 5 can be adjusted arbitrarily in the range of 360°, which is convenient for the dolly to be fixed on various workpieces of different shapes. The track trolley at the head end of the track trolley chain is connected to the track trolley at the tail end through the tensioning mechanism 4, and the track trolley chain and the tensioning mechanism 4 form a ring-shaped support structure; the outer side of the track trolley chain is provided with a transmission chain 6, and each track trolley 2 The tops of the tops are all connected with the transmission chain 6 by thread pairs, and the head and tail ends of the transmission chain 6 are respectively arranged on the track trolley 2 at the head en...

Abstract

The invention discloses a telescopic transmission device, which comprises a sprocket box and a track trolley chain. The track trolley chain is composed of a plurality of track trolleys hinged at the head and tail. The track trolley at the head end of the track trolley chain is connected to the track trolley at the tail end through a tensioning mechanism. The track trolley chain and the tensioning mechanism form a ring-shaped support structure. The outer side of the track trolley chain is provided with a transmission chain. The top of each track trolley is connected to the transmission chain through a threaded pair. Engage with the second large sprocket. The transmission parts in the present invention adopt modular design, can be freely combined according to the requirements of working conditions, and have a wide range of uses. They can be used for linear transmission or arc motion trajectory transmission, and the tension mechanism can be adjusted For the screw pair, the tensioning of the transmission chain is realized, which is simple, quick and convenient.

Description

technical field [0001] The invention belongs to the technical field of pipe cutting and welding, and in particular relates to a telescopic transmission device. Background technique [0002] With the increasing demand for energy transmission, the laying of pipelines has become the main carrier of energy transmission, and the process of pipeline laying involves cutting and welding of pipelines. However, it is difficult for the existing transmission mechanism to meet the requirements of cutting and welding and adapt to the change of different pipe diameters at the same time. It is particularly important to develop a set of transmission devices that can freely expand and contract. Contents of the invention [0003] The purpose of the present invention is to provide a telescopic transmission device, which can be used for the transmission of pipe cutting and welding, and can simultaneously change the transmission structure according to the change of the diameter of the pipe. ...
