Description

Technical Field

[0001] This utility model relates to the technical field of a coal conveying and transferring mechanism for power plants with double hoisting, and more particularly to a coal conveying and transferring mechanism for power plants with double hoisting. Background Technology

[0002] Coal transfer mechanisms in power plants refer to the equipment or facilities used to transfer coal from one conveying stage to another in thermal power plants. These transfer mechanisms typically include conveyor belts, transfer stations, coal crusher rooms, and coal bunkers.

[0003] The existing hoisting systems of coal conveying and transfer mechanisms have certain limitations. When handling large or heavy coal transportation, the efficiency is low when moving because the hoisting weight of a single hoisting system is limited. When handling small coal transportation in multiple groups, although the hoisting weight is small, the efficiency is also low because there is only a single hoisting structure. The hoisting system lacks flexibility and cannot adapt to different transportation needs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a coal conveying and transfer mechanism for power plants with double hoisting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coal conveying mechanism for power plants with dual hoisting features includes a support frame. The bottom of the support frame is fixedly equipped with movable wheels. The top of the support frame has a first movable groove and a second movable groove. A first rotating rod is movably installed in the middle of the first movable groove, and a second rotating rod is movably installed in the middle of the second movable groove. A first drive motor is fixedly installed on the left side of the support frame corresponding to the position of the first rotating rod, and the output end of the first drive motor is fixedly connected to the first rotating rod. A second drive motor is fixedly installed on the left side of the support frame corresponding to the position of the second rotating rod, and the output end of the second drive motor is fixedly connected to the second rotating rod. A controller is fixedly installed on the right side wall of the support frame.

[0007] As a further embodiment of this utility model, a first movable block is movably installed in the first movable slot, and the first movable block is threadedly connected to the first rotating rod. A second movable block is movably installed in the second movable slot, and the second movable block is threadedly connected to the second rotating rod. A crane is fixedly installed on the top of both the first and second movable blocks, and a wire rope is movably installed on the bottom of both the first and second movable blocks. A lifting device is fixedly installed at the bottom end of the wire rope.

[0008] As a further embodiment of this utility model, a first gear is provided on the right side wall of the support frame at the position corresponding to the first rotating rod, and the first gear is fixedly installed on the first rotating rod. A second gear is provided on the right side wall of the support frame at the position corresponding to the second rotating rod, and the second gear is fixedly installed on the second rotating rod. A connecting gear is provided between the first gear and the second gear.

[0009] As a further embodiment of this utility model, a connecting frame is provided on the outer side of the connecting gear, the connecting gear is movably mounted on the top of the connecting frame, a servo motor is provided at the bottom of the connecting frame, a fixing frame is fixedly mounted at the bottom of the servo motor, the fixing frame is fixedly mounted on the side wall of the support frame, and a threaded rod is fixedly mounted at the output end of the servo motor.

[0010] As a further embodiment of this utility model, a limiting groove is provided on the side wall of the support frame corresponding to the position of the connecting frame, and a limiting block is fixedly installed at the bottom end of the side wall of the connecting frame, and the limiting block can be movably engaged in the limiting groove.

[0011] As a further embodiment of this utility model, the bottom of the connecting frame is provided with a threaded groove, and the threaded groove is threadedly connected to the threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the movable wheels at the bottom of the support frame facilitate the movement of the mechanism. When handling the transportation of small, multi-unit coal, the controller can control the first and second drive motors to rotate independently. The first and second drive motors can drive the first and second rotating rods to rotate. The first and second rotating rods can control the first and second movable blocks to move in the first and second movable slots, thereby enabling the lifting devices at the bottom of the first and second movable blocks to transport small coal units independently, thus improving transportation efficiency.

[0014] 2. In this utility model, the controller controls the first movable block and the second movable block to move to the rightmost side of the first movable slot and the second movable slot. At this time, the servo motor is started to drive the threaded rod to rotate. The threaded rod will push the connecting frame to move upward. When the connecting frame moves upward, it will drive the connecting gear to move upward. At this time, the connecting gear will mesh with the outer sides of the first gear and the second gear. Then, the controller starts the first drive motor and the second drive motor to rotate, so that the first movable block and the second movable block can move synchronously on the support frame, which effectively increases the lifting weight of a single operation, thereby improving the transportation and movement efficiency when transporting large or heavy coal.
