A support mechanism and a rope gripper for endless rope

Abstract

The present invention discloses a support mechanism and a rope gripper for endless ropes, relating to the technical field of endless rope drives. It includes a front swing-opening and closing support wheel assembly, a rear closing support wheel assembly, and a running track welding assembly. The front swing-opening and closing support wheel assembly and the rear closing support wheel assembly are respectively fixedly arranged on both sides of the running track welding assembly. The endless rope sequentially passes through the center of the front swing-opening and closing support wheel assembly and the center of the rear closing support wheel assembly to form a closed loop. Both the front swing-opening and closing support wheel assembly and the rear closing support wheel assembly are used to support the endless rope. The present invention can solve the problem of the endless rope sagging due to its own weight. At the same time, when the rope gripper passes through the front swing-opening and closing support wheel assembly, the rope gripper will automatically push open the front swing-opening and closing support wheel assembly and thus pass through smoothly. After the rope gripper passes through, the front swing-opening and closing support wheel assembly automatically resets and continues to support the endless rope, while the rear closing support wheel assembly always supports the endless rope during the running of the endless rope.

Description

Technical Field

[0001] The present invention relates to the technical field of endless rope drives, and in particular to a support mechanism and a rope gripper for an endless rope. Background Art

[0002] Endless rope transportation is a continuous transportation method that uses a closed-loop steel wire rope to tow mine cars to transport materials. At one end of the transportation roadway, a driving wheel is provided, and a tail wheel is installed at the other end. The steel wire rope is wound around the driving wheel and the tail wheel to form a circulating endless traction group. The motor drives the driving wheel to rotate, and the friction force is used to drive the steel wire rope to move continuously, thereby realizing the transportation of materials.

[0003] In long-distance endless rope drives, even when the endless rope is in a tensioned state, the endless rope will still sag due to its own weight. This sag of the endless rope, on the one hand, affects the uniformity and timeliness of the power transmission of the endless rope, and on the other hand, the sagging endless rope will also affect the normal operation of the load fixed on the steel wire rope.

[0004] Therefore, there is an urgent need for a support mechanism and a rope gripper for an endless rope. Summary of the Invention

On the side of the sliding member 42 away from the positioning bump, there is a second clamping surface 422. The first clamping surface 412 and the second clamping surface 422 cooperate to press the endless rope 5 tightly.

[0099] In this embodiment, by tightening the clamping bolt 3, the sliding member 42 can be moved forward to press the endless rope 5 tightly onto the fixing member 41.

[0100] Both ends of the fixing member 41 and the sliding member 42 are symmetrical wedge-shaped structures, which are used to drive the front swing opening and closing support wheel assembly 1 to open.

[0101] In this embodiment, when the rope gripper moves towards one end, when the wedge-shaped structure at one end of the fixing member 41 contacts the front swing opening and closing support wheel assembly 1, the upper and lower groups of front swing support wheel groups 14 swing open. After the rope gripper passes through, the upper and lower groups of front swing support wheel groups 14 respectively reset to the vertical state under the action of the second lower swing torsion spring 12 and the second upper swing torsion spring 17. When the rope gripper moves towards the other end, when the wedge-shaped structure at the other end of the fixing member 41 contacts the front swing opening and closing support wheel assembly 1, the upper and lower groups of front swing support wheel groups 14 swing open. After the rope gripper passes through, the upper and lower groups of front swing support wheel groups 14 respectively reset to the vertical state under the action of the first lower swing torsion spring 11 and the first upper swing torsion spring 16.
