Description

Technical Field

[0001] This application relates to the field of transportation technology, and more particularly, to a U-shaped steel transportation device for coal mine uphill and downhill roadways. Background Art

[0002] Due to the large bearing pressure of U-shaped steel supports, which are easy to install and not easy to deform, they are currently widely used in coal mines. However, the existing mine cars have limited carrying capacity, and not all roadways are equipped with tracks. Especially in the uphill and downhill roadways where there are no mine cars, manual handling is required, which not only affects production efficiency but also poses a safety hazard of U-shaped steel injuring people. Summary of the Invention

[0003] To make up for the above deficiencies, this application provides a U-shaped steel transportation device for coal mine uphill and downhill roadways.

[0004] An embodiment of this application provides a U-shaped steel transportation device for coal mine uphill and downhill roadways, including driving rollers. There are two sets of the driving rollers, and a belt is drivingly connected between the two sets of driving rollers. Fixed pulleys are arranged above the two sets of driving rollers. The fixed pulleys are arranged on the rock mass, and a towing rope is drivingly connected between the fixed pulleys and the driving rollers. A movable pulley is arranged on the towing rope, and a fixed frame is arranged outside the towing rope. The movable pulley is installed between the fixed frames, and the towing rope is clamped below the movable pulley. A connecting rod is welded to the lower surface of the fixed frame, and a placing plate for placing U-shaped steel is welded to the bottom of the connecting rod. An anti-tilting mechanism is arranged at the bottom of the fixed frame, and the anti-tilting mechanism is arranged on the top of the U-shaped steel.

There are four sets of guide rods, and the bottoms of the four sets of guide rods are all welded to the upper surface of the pressing plate, and the tops of the four sets of guide rods are all slidably arranged in the fixed frame.

[0015] During the above implementation process, through the arranged guide rods, the pressing plate can be guided, enabling the pressing plate to move up and down in a straight line without rotation, increasing the stability of the pressing plate.

[0016] In a specific embodiment, the first fixing mechanism includes a convex plate and a first fastening bolt. The convex plate is welded to the top of the synchronization rod. There are two sets of first fastening bolts, and the two sets of first fastening bolts are symmetrically arranged on both sides of the convex plate, and the convex plate is fixedly connected to the fixed frame through the first fastening bolts.
