Embodiment 1

[0020] see Figure 1-3 , a coal mine underground conveying device, comprising a bearing box 7, a base plate 5, a main shaft support 17, a bearing support 11, a main shaft 16 and crawler belts 2, wherein the base plate 5 is fixedly mounted on the bearing support 11, and the main shaft support 17 The two ends of the bearing bracket 11 are fixedly installed, and the driving wheel 3 is rotatably installed on the main shaft bracket 17. The specific number of the driving wheel 3 is not limited. In this embodiment, preferably, the driving wheel 3 Four wheels 3 are equidistantly arranged on the main shaft bracket 17. The main shaft 16 is rotatably mounted on the driving wheel 3, and the driving device is fixedly installed on the main shaft 16, and the driving device is further driven by the driving device. The driving wheel 3 rotates, and the crawler belt 2 is expanded and installed on the outside of the driving wheel 3, and then when the driving wheel 3 rotates, the rotation of the c...

Embodiment 2

[0028] In order to make the crawler belt 2 of the device more stable when rotating, the present embodiment makes the following improvements on the basis of the first embodiment. The improvement is that the main shaft support 17 is rotatably mounted with several adjustment wheels 12 The adjustment wheel 12 is arranged above the main shaft support 17, and the interference between the crawler belt 2 and the main shaft support 17 is effectively avoided by the adjustment wheel 12.

[0029] The working principle of this embodiment: by rotating and installing several adjusting wheels 12 on the main shaft support 17 , the interference between the caterpillar belt 2 and the main shaft support 17 is avoided through the adjustment wheels 12 .

Abstract

The invention discloses an underground coal mine conveying device. The underground coal mine conveying device comprises a bearing box, a bottom plate, spindle supports, a bearing support, spindles andcrawler belts; the bottom plate is fixedly installed on the bearing support; the spindle supports are fixedly arranged at two ends of the bearing support; driving wheels are rotationally mounted on the spindle supports; the spindles are rotationally mounted on the driving wheels; the spindles are fixedly provided with driving devices, the driving devices drive the driving wheels to rotate, the crawler belts are installed on the outer sides of the driving wheels in an expanding mode, one end of the bearing box is installed on the bottom plate through rotation of the rotating shaft, the bottomplate is provided with a pushing device, and the pushing device pushes the bearing box to rotate. The underground coal mine conveying device is simple in structure, and a complex underground environment can be effectively used through crawler belt transmission; and meanwhile, when the crawler belts encounter an obstacle, tensioning adjustment of the crawler belts can be effectively conducted through the connecting rods and the adjusting springs, and then the applicability of the device is greatly improved.

Description

technical field [0001] The invention relates to a transportation device, in particular to a coal mine underground transportation device. Background technique [0002] Mine transportation is characterized by large transportation volume, many varieties, narrow roadways, different transportation distances, complex routes, and short visible distance, so the operation is complicated, maintenance is difficult, and safety requirements are high. Mine belt conveyors are often used in existing mines; mine belt conveyors have the characteristics of large transportation volume, complex working environment, strong carrying capacity, and long transportation distance; thus they are widely used. A trolley type coal block transport device is needed in the mine to assist the coal mining work. [0003] For now, a trolley-type coal mine underground conveying device is needed in the mine to assist the coal mining work; most of the existing coal mine underground conveying devices adopt the rolle...
