Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, and in particular relates to a roller device for winch wire ropes of electric shovels. Background Technology

[0002] Electric shovels are large mining equipment used in metallurgical mines. During operation, a winch reducer repeatedly winds a wire rope to lift the shovel and unload ore. Since the wire rope between the winch reducer and the main frame sheave is approximately 10 meters long, to prevent it from rubbing against the front canopy of the shovel due to its own weight and causing damage, the original design included rollers made of 45# steel installed on both sides of the front canopy of the shovel, below the wire rope, which could roll along with the moving wire rope. However, modern electric shovels use wire ropes with extended service life... The outer layer is fitted with a hard plastic protective sleeve. During excavation operations, electric shovels often encounter relatively hard ore. When the bucket digs, the increased resistance causes the winch wire rope to vibrate significantly. The wire rope constantly impacts and rubs against the idler roller. Frequent rigid impacts and friction directly cause the outer protective sleeve of the wire rope to wear out and break. The direct impact and friction between the wire rope and the idler roller also leads to accelerated wear and shortens the service life of the wire rope. This not only increases the cost of the equipment, but also poses a hidden danger to the safe and stable operation of the electric shovel due to the uncertainty that the winch wire rope may break at any time. Summary of the Invention

[0003] The purpose of this invention is to provide a roller device for the winch wire rope of an electric shovel, which can reduce the impact and wear of the winch wire rope, thereby effectively improving the service life of the winch wire rope, reducing equipment operating costs, and promoting the safe and stable operation of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution: The present invention relates to a roller device for winch wire ropes of electric shovels, characterized in that it includes a roller shaft mounted on a roller bearing, a nylon roller connected to the roller shaft, a roller bearing fixing sleeve mounted on the outside of the roller bearing, and fixed roller angle irons and roller shaft nuts respectively mounted at both ends of the roller shaft.

[0005] The fixed roller angle iron is fixedly connected to the carport by connecting screws.

[0006] Advantages of this utility model: This utility model relates to a roller device for the winch wire rope of an electric shovel. It is simple to manufacture, low in cost, and flexible in disassembly and assembly. It effectively reduces the wear and damage caused by the rigid impact and friction between the winch wire rope and the roller, extends the service life of the winch wire rope, reduces equipment costs, and effectively promotes the safe and stable operation of electric shovel equipment. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0008] The specific embodiments of this utility model are further described below with reference to the accompanying drawings.

[0009] like Figure 1 As shown, the idler roller device for electric shovel winch wire rope of this utility model is characterized by comprising an idler roller shaft 7 mounted on an idler roller bearing 4, a nylon idler roller 2 connected to the idler roller shaft 7, an idler roller bearing fixing sleeve 3 mounted on the outside of the idler roller bearing 4, and idler roller fixing angle irons 6 and idler roller shaft nuts 8 respectively mounted at both ends of the idler roller shaft 7. The fixed roller angle iron 6 is fixedly connected to the carport by connecting screws 5.

[0010] This invention relates to a roller device for electric shovel winches that effectively reduces wear and provides cushioning. The device includes a nylon roller 2, a roller bearing fixing sleeve 3, a roller bearing 4, connecting screws 5 for fixing the roller angle iron to the shed, a fixing roller angle iron 6, a roller shaft 7, and a roller shaft nut 8. The roller, originally made of 45# steel, is replaced with a nylon roller. During electric shovel digging operations, the strong impact and friction between the electric shovel winch wire rope 1 and the roller is changed from rigid contact to a cushioned contact through the nylon roller. This not only reduces wear on the protective film on the outer layer of the winch wire rope, extending its service life, but also more effectively reduces friction between the winch wire rope and the roller, further extending the service life of the electric shovel winch wire rope 1 and reducing its operating cost. The extended service life of the protected electric shovel winch wire rope 1 also promotes the safe and stable operation of the electric shovel equipment.

[0011] Detailed installation process: 1. Based on the installation diagram of the electric shovel winch wire rope idler, manufacture two nylon idler rollers, two idler roller bearing fixing sleeves, two idler roller bearings, several connecting screws, two idler roller fixing angle irons, two idler roller shafts, and four idler roller shaft nuts.

[0012] 2. Assemble the two sets of idler roller devices as shown in the attached diagram. The specific assembly method is as follows: First, install the four idler roller bearings 4 into the holes on one side of the corresponding four idler roller bearing fixing sleeves 3 according to the external dimensions. Then, referring to the attached diagram, insert the idler roller shaft 7 into the nylon idler roller 2 and the other idler roller bearing fixing sleeve 3 in sequence. Install the idler roller angle irons 6 at both ends of the idler roller shaft 7. Then, install the idler roller shaft nuts 8 at both ends of the idler roller shaft 7 and tighten them to complete the assembly of the idler roller. In the same way, assemble the other idler roller at the same time.

[0013] 3. Remove the original idler roller from the electric shovel. Place the improved idler roller in the same position as the original idler roller. Align the roller with the screw holes of the angle iron fixing roller and install and tighten the connecting screw 5. Repeat the same process on the other side to complete the replacement.

[0014] This utility model relates to a roller device for the winch wire rope of an electric shovel. It is simple to manufacture, low in cost, and flexible in disassembly and assembly. It effectively reduces the wear and damage caused by the rigid impact and friction between the winch wire rope and the roller, extends the service life of the winch wire rope, reduces equipment costs, and effectively promotes the safe and stable operation of electric shovel equipment.
