Description

Technical Field

[0001] This utility model relates to the field of engineering machinery maintenance tools, and in particular to a guide tool for replacing conveyor belts in coal conveying corridors. Background Technology

[0002] Belt conveyors are widely used for material transport in industries such as coal mining. Over long-term use, belts inevitably experience irreversible wear and tear, necessitating timely replacement. Currently, the common method for belt replacement involves pulling the old belt along its length until it is removed from the belt support, then vulcanizing both ends of the new belt and connecting them. However, this method has significant limitations, especially in confined spaces such as coal conveyor corridors. Due to space constraints, belt replacement cannot be performed in the conventional way, making the replacement operation extremely complex, consuming significant manpower and resources, and prolonging equipment downtime, thus impacting production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a guide tool for replacing conveyor belts in coal conveying corridors, thereby solving the problem of complex conveyor belt replacement operations in locations with limited space.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A guide tool for replacing conveyor belts in a coal conveyor corridor includes: The base plate, used to support the guide tool, provides a stable support foundation for the entire device. It can be made of 10mm thick stainless steel plate to ensure that it has sufficient strength and corrosion resistance. The support column is fixedly connected to the center of the base plate and can be firmly connected to the base plate by welding or other methods. Its material is stainless steel. The support frame is mounted on the support column, and the support frame is equipped with rollers for guiding the belt. The rollers are made of stainless steel and their surfaces are polished to reduce the friction between the belt and the rollers.

[0005] Furthermore, the support frame includes two horizontal plates arranged side by side, and the shaft ends of the roller are respectively fixedly connected to the two horizontal plates.

[0006] Furthermore, guide cylinders are arranged parallel to the rollers between the horizontal plates. The shaft ends of the guide cylinders are fixedly connected to the two horizontal plates respectively. Their function is to further assist in guiding the belt and reduce the friction of the belt during the replacement process.

[0007] Furthermore, the horizontal plate is fixedly connected to the support column, which can be achieved by welding or bolting. This connection method has a simple structure, good stability, and is suitable for scenarios where the height adjustment requirement is not high.

[0008] Furthermore, the horizontal plate is slidably connected to the support column, and a telescopic device is fixedly connected to the upper horizontal plate. The bottom of the telescopic device is fixed to the base plate. Through this sliding connection and the cooperation of the telescopic device, the height of the support frame can be flexibly adjusted according to actual needs.

[0009] Furthermore, a cylinder is fixedly connected between the horizontal plates, and the cylinder is slidably connected to the support column.

[0010] Furthermore, the telescopic device employs a jack or an electric hydraulic cylinder.

[0011] Furthermore, mounting holes are provided on the base plate, and expansion screws are installed in the mounting holes for fixing the base plate.

[0012] Furthermore, a reinforcing plate is fixedly connected to the support column, and the reinforcing plate is fixedly connected to the base plate.

[0013] Furthermore, the base plate, support column, support frame, and roller are all made of stainless steel, and their connection method is welding.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By installing a base plate, support columns, and a support frame with rollers, effective guidance can be provided for belt replacement in space-constrained locations such as coal conveyor corridors. The rollers reduce friction during belt replacement, making the process smoother and significantly improving efficiency. Simultaneously, they reduce operational complexity and labor intensity, minimize equipment downtime, and ensure continuous production. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the main structure of an embodiment of the present utility model.

[0016] In the above attached figures: base plate 1, support column 2, support frame 3, horizontal plate 31, roller 4, guide cylinder 5, telescopic device 6, cylinder 7, expansion screw 8, reinforcing plate 9. Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1 like Figure 1As shown, a guide tool for changing belts in a coal conveyor corridor includes a base plate 1, a support column 2, and a support frame 3. The base plate 1 is made of 10mm thick stainless steel and provides stable support for the entire guide tool. The support column 2, made of 50mm diameter stainless steel and 1200mm high, is fixedly connected to the center of the base plate 1 and is securely welded to the base plate 1, supporting the support frame 3 above. The support frame 3 includes two parallel horizontal plates 31, made of 8mm thick stainless steel, with a distance of 720mm between them. The shaft ends of a roller 4 are fixedly connected to the two horizontal plates 31. The roller 4 is made of stainless steel, has a diameter of 150mm, and a length of 680mm. The horizontal plates 31 are fixedly connected to the support column 2 by welding. In use, the base plate 1 is fixed to the ground of the coal conveying corridor with expansion bolts. During the replacement process, the belt is placed on the roller 4. The roller 4 can reduce the friction when the belt moves, thereby guiding the belt and facilitating belt replacement operations in the limited space of the coal conveying corridor.

[0019] Example 2 The difference between this embodiment and Embodiment 1 is that a guide cylinder 5 is arranged parallel to the roller 4 between the horizontal plates 31. The guide cylinder 5 is made of stainless steel, with a diameter of 100mm and a length of 680mm, and its shaft ends are fixedly connected to the two horizontal plates 31 respectively. By adding the guide cylinder 5, the belt is further guided, preventing the belt from shifting during the replacement process, making the belt replacement process more stable and reliable.

[0020] Example 3 In this embodiment, the horizontal plate 31 and the support column 2 are slidably connected. A telescopic device 6, which is a jack, is fixedly connected to the upper horizontal plate 31, and its bottom is fixed to the base plate 1. A cylinder 7 is fixedly connected between the horizontal plates 31, and the cylinder 7 is slidably connected to the support column 2. The inner diameter of the cylinder 7 is 5mm larger than the outer diameter of the support column 2. When it is necessary to adjust the height of the support frame 3, the jack is operated to extend or retract its piston rod, thereby driving the horizontal plate 31 to slide up and down along the support column 2, realizing the adjustment of the height of the support frame 3 to adapt to belt replacement work with different height requirements.

[0021] Example 4 The difference between this embodiment and Embodiment 3 is that the telescopic device 6 uses an electric hydraulic cylinder. The electric hydraulic cylinder can be automatically controlled by a control system, making operation more convenient and allowing for precise adjustment of the height of the support frame 3, thus improving work efficiency and operational accuracy. In practical applications, a suitable telescopic device can be selected based on the specific working environment and operational requirements.

[0022] Four mounting holes are evenly distributed on the base plate 1. Expansion screws 8 are installed in the mounting holes to securely fix the base plate 1 to the ground. A reinforcing plate 9, made of 6mm thick stainless steel and triangular in shape, is fixedly connected to the support column 2 and the base plate 1 by welding. The mounting holes and expansion screws 8 ensure that the base plate 1 is securely installed; the reinforcing plate 9 enhances the connection strength between the support column 2 and the base plate 1, improves the stability of the entire guide tool, and enables it to better withstand various forces during belt replacement.

[0023] In this embodiment, all components, including the base plate 1, support column 2, support frame 3, roller 4, guide cylinder 5, and cylinder 7, are made of stainless steel, and all connections between components are made by welding. This material selection and connection method ensures that the guiding tool has good corrosion resistance, adapts to harsh working environments such as coal conveying corridors, and at the same time, the welding connection method makes the connections between components firm, the structure stable, extends the service life of the equipment, and ensures the smooth operation of belt replacement.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
