[0001] The invention relates to the technical field of mine rescue equipment, in particular to a belt conveyor for quickly clearing a rescue channel during underground rescue. Background Art

[0002] With rapid economic development, nearly 20,000 kilometers of mine roadways and tunnels are excavated annually, and mine collapse accidents are a common occurrence. When people are trapped, safely and efficiently constructing a rescue tunnel is the most effective method. Currently, mine collapse rescue efforts still primarily rely on excavating small pilot tunnels and tunneling around tunnels, resulting in low efficiency and poor safety. When underground mines and tunnels are ready for construction, using an underground rescue drill to construct a large-diameter rescue tunnel through the collapsed section is the most direct, safest, and most efficient method. A device is then installed in the narrow space below the rescue drill to transport the excavated material.

[0003] However, due to the narrow space of the channel, the commonly known belt conveyor has the problems of being large, bulky and heavy, and it is difficult to install it in the channel to transport the materials in the narrow space outward; moreover, this belt conveyor is not easy to disassemble and is troublesome to install.

[0013] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] like Figure 1As shown, this embodiment exemplarily shows a belt conveyor for quickly clearing a rescue channel for underground rescue, including a frame, which includes a head section frame 1, a middle section frame 2 and a tail section frame 3. The tail of the head section frame 1 is hinged to the front end of the middle section frame 2, and the tail of the middle section frame 2 is connected to the front end of the tail section frame 3 by bolts and nuts to form a horizontal section frame. The lower end surface of the front end of the head section frame 1 is detachably connected to a vertically arranged support leg 5. For example, when the support leg 5 is installed, the angle between the head section frame 1 and the horizontal plane of this embodiment is 13°; the head of the head section frame 1 is rotatably installed with a belt drive pulley 4, which is driven by a hydraulic motor installed on the head section frame 1, and the tail of the tail section frame 3 is directly connected to the head section frame 3 through a spiral tensioning device 10 (which can be directly used The patent application number applied by our company is CN202121456186.3, and the patent name is a spiral tensioning device at the tail of a belt conveyor, whose main function is to adjust the belt deviation and tighten the belt). It is equipped with a belt driven pulley 6, and a conveyor belt 7 is connected between the belt driving pulley 4 and the belt driven pulley 6; height-adjustable upper conveyor belt rollers 9 are respectively provided between the two side walls of the head section frame 1, the middle section frame 2 and the tail section frame 3, and height-adjustable lower conveyor belt rollers 11 are respectively provided between the two side walls of the middle section frame 2 and the tail section frame 3, and height-adjustable lower conveyor belt pressure rollers 12 are respectively provided between the front end of the middle section frame 2 and the two side walls of the tail of the head section frame 1, and upper conveyor belt pressure rollers 13 are provided at the front end of the middle section frame 2 and both sides of the tail of the head section frame 1.

[0015] Several strip holes 8 are respectively opened on the two side walls of the head section frame 1, the middle section frame 2 and the tail section frame 3. The two ends of the roller shaft of the upper conveyor belt roller 9 / the lower conveyor belt roller 11 / the lower conveyor belt pressure roller 12 pass through the strip holes 8 on both sides. A limit block is provided outside the strip hole 8 and is fixed to the outer side wall of the frame by bolts. A bearing is fixed in the limit block, and the end of the roller shaft is fixed in the inner ring of the bearing. The height of the roller can be adjusted by cooperating with the strip hole 8 and the limit block.

[0016] like Figure 2 As shown, the upper conveyor belt pressure roller 13 is mounted on both sides of the frame via brackets 14 and bearing seats. The brackets 14 are fixed to the two side walls of the frame, and the bearing seats are fixed to the upper end faces of the brackets 14. A bearing is fixed in the bearing seats. One end of the roller shaft of the upper conveyor belt pressure roller 13 is fixed in the inner ring of the bearing. The lower end face of the upper conveyor belt pressure roller 13 contacts the upper end face of the upper conveyor belt 7. The upper conveyor belt pressure roller 13 of this embodiment is mainly used to correct the deviation of the conveyor belt 7.

[0017] When in use, directly under the rescue drilling rig, the tail of the head section frame 1 is connected to the front end of the middle section frame 2 through a hinged plate, and the tail of the middle section frame 2 is connected to the front end of the tail section frame 3 by bolts and nuts to form a horizontal section frame. According to the angle of the head section frame 1, the support legs 5 of the corresponding height need to be installed, and then the belt driving pulley 4, the belt driven pulley 6 and the conveyor belt 7 are installed. After that, the corresponding upper conveyor belt roller 9, the lower conveyor belt roller 11, the lower conveyor belt pressure roller 12 and the upper conveyor belt pressure roller 13 are installed. The tightness of the entire conveyor belt 7 is adjusted by adjusting the height of the upper conveyor belt roller 9, the lower conveyor belt roller 11 and the lower conveyor belt pressure roller 12 and adjusting the spiral tensioning device. Finally, the belt driving pulley 4 is driven by a hydraulic motor to complete the assembly of the entire belt conveyor. The hydraulic motor and the rescue drilling rig share the same hydraulic system. The entire equipment is directly placed under the rescue drilling rig, does not need to be fixed on a foundation, moves with the equipment, is light in weight, and is easy to move, and can transport the slag materials drilled by the rescue drilling rig to the outside.
