Description

Technical Field

[0001] The utility model relates to the technical field of mine car stopping, and more specifically, to a roadway car arrester in coal mines Background Art

[0002] In coal mine production operations, underground operations are the main operations of coal mines. In underground operations, a main tool for transporting items is a mine car. The mine car uses a winch as the traction power and runs on a laid track. The car is loaded with items to be transported such as coal, tools, equipment, etc. The roadway car arrester in a mine is a safety device widely used in mines. Its main function is to quickly stop and fix transport vehicles in case of abnormal situations in the mine roadway, protecting the lives of workers and the integrity of mine equipment. Most of the existing car arresters are made of wedges made of wood or steel. Manually place them on one side of the lower end of the mine car wheel, and use the wedge to prevent the mine car wheel from moving, but there is no fixation between the car arrester and the railway track, which affects the effect of blocking the vehicle. For this reason, we propose a roadway car arrester in coal mines Content of the Utility Model

[0035] Working principle: When blocking and fixing the mine car, first hold the handle groove 17 by hand to place the car blocking clamp 3 on the rail 2, so that the top end of the rail 2 is inserted into the card slot 5 below the car blocking clamp 3. At the same time, move the car blocking clamp 3 to drive the end face of the car blocking inclined seat 10 to abut against the wheel of the mine car. Then rotate the first rotating block 9 to drive the first screw rod 8 to rotate. Through the thread fit between the first screw rod 8 and the first welding nut 7, drive the end of the first screw rod 8 to move, so that the end of the first screw rod 8 abuts against the side of the rail 2. Use the extrusion fit between the first screw rod 8 and the rail 2 to fix between the rail 2 and the car blocking clamp 3. Finally, rotate the second rotating block 16 to drive the second screw rod 14 to rotate. Through the thread fit between the second screw rod 14 and the second welding nut 13, drive the screw 15 to rotate downward, so that the bottom end of the screw 15 is spirally screwed into the interior of the mine roadway foundation 1, and use the mine roadway foundation 1 to strengthen and fix the car blocking clamp 3 to ensure the stability of the car blocking clamp 3 and the car blocking inclined seat 10 to block the mine car, that's all.
