Rack and scraper conveyor comprising same

Abstract

The invention discloses a rack for a scraper conveyor. The rack comprises a bottom bracket (1) and a main rack body (2) supported by the bottom bracket (1), wherein the two sides of the main rack body (2) are provided with side plates (21) respectively; the two sides of the bottom bracket (1) are provided with vertical plates (11) opposite to the side plates (21) respectively, and the distance between inner walls of the two vertical plates (11) is slightly greater than the distance between outer walls of the two side plates (21); and the lower end part of the main rack body (2) is arranged between the two vertical plates (11) and the vertical plates (11) are connected with the side plates (21) on the same side. The rack can conveniently adjust the mounting height and mounting angle. Besides, the invention also discloses the scraper conveyor comprising the rack.

Description

technical field [0001] The invention relates to the technical field of scraper conveyors, in particular to a frame for scraper conveyors. The invention also relates to a scraper conveyor comprising the above frame. Background technique [0002] In the coal mine industry, the frame of the coal mine scraper conveyor has three major functions: first, the frame is the driving frame of the chain transmission mechanism, the driving sprocket is installed on the frame, and the transmission device composed of the motor and the reducer and the chain Wheel butt. When the scraper conveyor is running, the sprocket drags the scraper chain to transport coal and other materials. Second, the position of the head of the scraper conveyor where the frame is located is the unloading position of coal materials, and the materials of the end-unloading structure frame are unloaded at the front end of the sprocket. Thirdly, the frame is the anchor connection point of the support and moving devices...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, when the installation height needs to be adjusted, the bottom bracket 1' needs to be redesigned, the height of the bottom bracket 1' in the vertical direction is adjusted up or down, and then the adjusted bottom bracket 1' is installed with the main frame body 2', obviously, figure 1 The rack shown is extremely inconvenient to adjust the mounting height of the rack

In addition, when the installation angle of the frame needs to be adjusted, the bottom bracket also needs to be redesigned, and the assembly relationship between the main frame body 2' and the bottom bracket 1' needs to be adjusted, which is also extremely inconvenient

[0006] In addition, if figure 1 As shown, since the main frame body 2' and the bottom bracket 1' are connected by bolts, and the number of bolts is large, the installation is inconvenient
