Middle supporting device capable of achieving length self-adaptation

Abstract

The invention discloses a middle supporting device capable of achieving length self-adaptation. The middle supporting device comprises a hollow rotating sleeve. The rotating sleeve is provided with atleast one auxiliary rotating hole. An internal thread is arranged inside the rotating sleeve, and the two ends of the rotating sleeve are each internally connected with a threaded connecting rod in amatched mode. One ends of the two threaded connecting rods are both arranged inside the rotating sleeve in a sleeved mode, and the other ends of the two threaded connecting rods both extend out of the rotating sleeve and are further arranged on corresponding contact bases. The two contact bases are both in a cylinder shape. According to the middle supporting device, the two threaded connecting rods can be stretched or retracted by rotating the rotating sleeve to be adapted to different horizontal distances between two independent face bodies; operation is convenient and can be completed by one person independently, time and labor are saved, and working efficiency is greatly improved; and moreover, half-movable circular supporting bases at the two ends can make contact with the independentface bodies, the supporting device can be horizontally or obliquely installed and can be suitable for being used between the two independent face bodies under different conditions, the application range is wide and safety performance is high.

Description

technical field [0001] The invention relates to a supporting device, in particular to an intermediate supporting device with an adaptive length. Background technique [0002] At present, when two independent surfaces parallel to each other or connected at one end are installed or removed, or when two independent surfaces or their tops need to be connected, welded, etc., such as welding between two partitions when an air preheater is installed, construction In the non-converging area of ​​the two independent surfaces, steel pipes, bottom plates, crowbars, electric welding, etc. are generally used to support auxiliary operations. The installation and use of these supports are more complicated, time-consuming and laborious, and reduce work efficiency, especially in the independent surface space. Larger, or when the two independent surfaces are inclined to each other, and the space between the two independent surfaces is relatively narrow, the support tool is more difficult to i...

[0002] At present, when two independent surfaces parallel to each other or connected at one end are installed or removed, or when two independent surfaces or their tops need to be connected, welded, etc., such as welding between two partitions when an air preheater is installed, construction In the non-converging area of ​​the two independent surfaces, steel pipes, bottom plates, crowbars, electric welding, etc. are generally used to support auxiliary operations. The installation and use of these supports are more complicated, time-consuming and laborious, and reduce work efficiency, especially in the independent surface space. Larger, or when the two independent surfaces are inclined to each other, and the space between the two independent surfaces is relatively narrow, the support tool is more difficult to install, requires multiple people to work together, is difficult to operate, and has potential safety hazards
