Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor equipment application, in particular to an auxiliary device for replacing a coal conveying belt. Background Art

[0002] Belt conveyors have the advantages of large conveying capacity, low power, high efficiency and strong adaptability to materials. Therefore, belt conveyors are widely used in coal mines, steel mills, power plants and other fields. Especially in the coal transportation system of thermal power plants, due to various reasons such as long-term operation and mechanical wear, the coal conveyor belt needs to be replaced in time. At present, the method for replacing the coal conveyor belt is usually to pull the wire rope on the old belt, and drag the old belt out by manually pulling the wire rope. When installing the new belt, the wire rope is pulled on the new belt, and the new belt is dragged and installed on the coal conveyor by manually pulling the rope. When this method is used, there is usually a long time for belt disassembly and installation, and the replacement efficiency of the old and new belts is relatively low, resulting in a long downtime of the coal conveyor, which greatly affects the efficient operation of the boiler unit. At the same time, the operating safety of the operator is poor when replacing the belt, which has a great impact on the overall scientific management of coal transportation production.

[0005] An auxiliary device for replacing a coal conveyor belt comprises a belt frame, a mounting base is vertically provided on one side of the belt frame, a capstan is rotatably provided on the mounting base close to the belt frame, a plurality of first connecting rings are provided on the side of the mounting base, and the first connecting rings are all located at the bottom of the capstan, pulleys are provided between the first connecting rings, and the capstan and the first connecting rings located at the bottom of the pulley are also detachably connected with belt clamps.

[0006] Furthermore, a winch bracket is vertically provided on the side of the mounting base, and the winch and the winch bracket are rotatably connected.

[0007] Furthermore, a first rope is wound around the winch, a second rope is fixedly connected to the first connecting ring located at the bottom of the pulley, and both the first rope and the second rope are connected to the belt clamp.

[0008] Furthermore, the belt clamp is composed of mutually symmetrical connecting plates that are detachably connected, and a plurality of second connecting rings are fixedly provided on the connecting plates.

[0009] The utility model has the following beneficial effects:

[0010] The utility model provides an auxiliary device for replacing a coal conveying belt, which is mainly composed of a mounting base, a capstan, a connecting ring, a rope, a belt clamping plate, a bracket and other components. The old belt is clamped at the upper and lower sides of the end of the belt frame by two sets of belt clamps, and the belt clamping plate is connected to the capstan rope. After the old belt is cut off, the old belt is quickly disassembled by rotating and pulling the capstan, and then the new belt is hoisted to the tail of the belt frame, and the two sets of belt clamping plates are respectively clamped at the two ends of the new belt in turn, and the two ends of the new belt are respectively pulled from the upper and lower rollers of the belt frame to the head position by pulling the capstan rope. The new belt is then fixed and bonded, thereby completing the efficient and convenient disassembly and installation of the coal conveyor belt, greatly saving the time for replacing the belt, preventing personal injury caused by rope slippage, further improving the efficiency and safety of coal conveyor belt replacement, and promoting the overall efficiency of coal transportation production. It solves the current problem of long replacement time of the coal conveyor belt and long coal conveyor downtime due to the common method of manually pulling the belt for disassembly and installation in the process of replacing the coal conveyor belt, which ultimately causes low coal transportation efficiency and reduces the overall operating rate of the coal transportation boiler unit.
