[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] like Figures 1-5 As shown, a pressure belt connecting elbow device for an inclined belt conveyor includes an elbow assembly 301 detachably installed at the elbow of the inclined belt conveyor 310. The elbow assembly includes support frames 307 installed on both sides of the conveyor surface of the inclined belt conveyor. A pressure belt roller assembly 302, a belt deflector assembly 303, and a lower pressure belt roller 304 are installed on the support frames 307. The pressure belt roller assembly includes a pressure belt roller 305 rotatably installed on the support frames. The pressure belt roller applies pressure to the upper belt surface of the inclined belt conveyor. The belt deflector assembly includes a belt deflector 306 rotatably installed on the support frames. The belt deflector is installed upward and close to the side of the conveyor belt of the inclined belt conveyor. The lower pressure belt roller is rotatably installed between the support frames and applies pressure to the lower belt surface of the inclined belt conveyor.

[0027] Multiple pressure rollers 305 are installed side-by-side and rotate in a triangular arrangement with the belt guide rollers 306. These multiple parallel rotating pressure rollers provide more uniform and continuous pressure to the upper belt surface of the inclined belt conveyor, effectively suppressing belt slippage and deviation caused by material gravity and lateral forces during turns, thus reducing material spillage. The triangular arrangement of the pressure rollers and belt guide rollers creates a stable constraint system, ensuring the belt's running trajectory from multiple dimensions, significantly enhancing the anti-deviation effect, and ensuring smooth material transport at bends.

[0028] The support frame 307 has external bearing seats installed at both ends corresponding to the lower pressure roller, and a protective plate is fastened to the outside of the support frame. The external bearing seats 308 at both ends of the lower pressure roller greatly simplify the installation and disassembly process. When components show signs of wear, maintenance personnel can quickly replace them, reducing maintenance difficulty. The outer protective plates not only protect the internal structure and reduce interference from dust and debris, but also facilitate inspection and maintenance of internal components after disassembly, effectively improving maintenance efficiency.

[0029] The support frame has a mounting groove 309 corresponding to the position of the belt pulley assembly. The belt pulley bracket is installed in the mounting groove 309. The belt pulley is rotatably mounted on the belt pulley bracket. The belt-blocking surface of the belt pulley assembly protrudes from the inner side of the support frame.

[0030] The support frame 307 includes an interconnected base plate 312, a main plate 311, side plates 313, a first reinforcing plate 314, and a second reinforcing plate 315. The base plate 312 is installed at the bottom of the main plate 311, the side plates 313 are installed on both sides of the main plate 311, and the first and second reinforcing plates are installed between the two side plates. The support frame, composed of the interconnected base plate, main plate, side plates, and first and second reinforcing plates, significantly improves the overall strength and stability of the support frame. It maintains structural integrity when subjected to various forces generated by the belt conveyor, ensuring the stable operation of the belt pulley assembly, belt retainer assembly, and lower belt roller, thus guaranteeing long-term reliable operation of the equipment.

[0031] The belt pressure pulley assembly includes a belt pressure pulley shaft 316, which extends inward through the reinforcing plate and the main plate. The belt pressure pulley is rotatably mounted on the belt pressure pulley shaft via bearings. The belt guide pulley assembly includes a belt guide shaft 317, with a bearing 318, a belt guide pulley, a pressure plate 319, and bolts 320 coaxially mounted on the belt guide shaft. The belt pressure pulley assembly, with its shaft extending through the reinforcing plate and the main plate, and the belt pressure pulley rotatably mounted on the shaft via bearings, ensures flexible rotation of the belt pressure pulley, reduces running resistance, and stabilizes the belt pressure effect. In the belt guide pulley assembly, the bearings, belt guide pulley, pressure plate, and bolts are coaxially mounted on the belt guide shaft, ensuring smooth rotation of the belt guide pulley, improving the belt guide function, and providing solid support for the stable operation of the belt at bends.

[0032] The installation process for the above-mentioned device is as follows:

[0033] (1) Installation of the support frame:

[0034] First, prepare the support frame according to the dimensions and structure of the bends at the angled belt conveyor. The support frame consists of an interconnected base plate, main plate, side plates, and reinforcing plate one and reinforcing plate two. Place the base plate at appropriate positions on both sides of the conveyor surface corresponding to the bends at the angled belt conveyor, and securely fix the base plate to the relevant parts of the belt conveyor using bolts or other connectors to ensure stable installation. Next, install the side plates on both sides of the main plate, using welding or high-strength bolts to ensure a tight and perpendicular connection between the side plates and the main plate, forming a stable frame structure. Then, install reinforcing plate one and reinforcing plate two between the two side plates to further enhance the overall strength of the support frame. Reinforcing plate one and reinforcing plate two are also connected to the side plates by welding or bolts to ensure that the support frame remains stable and does not deform or get damaged when subjected to various forces generated by belt operation.

[0035] (2) Installation of the belt pressure roller assembly: The belt pressure roller assembly includes a belt pressure roller shaft and multiple belt pressure rollers arranged side by side and rotating. Extend the belt pressure roller shaft inward through the reinforcing plate and the main plate, ensuring the shaft is installed accurately and horizontally. Install bearings on the belt pressure roller shaft, and then rotate the belt pressure rollers onto the shaft via the bearings. Ensure that the spacing between the multiple belt pressure rollers is uniform during installation, so that a more uniform and stable pressure can be applied to the upper belt surface of the inclined belt conveyor during operation. After installation, check the rotational flexibility of the belt pressure rollers to ensure they rotate smoothly without jamming.

[0036] (3) Installation of the pulley assembly: Set the mounting groove on the support frame at the position corresponding to the pulley assembly, install the pulley bracket in the mounting groove, and use bolts and other fasteners to firmly fix the pulley bracket in the mounting groove to ensure that the pulley bracket is installed stably.

[0037] The belt guide pulley assembly includes a belt guide shaft, on which the bearing, belt guide pulley, pressure plate, and bolts are coaxially mounted. First, the bearing is installed in the inner hole of the belt guide pulley, then the belt guide pulley is installed on the belt guide shaft. Finally, the belt guide pulley is fixed to the belt guide shaft using the pressure plate and bolts, allowing the belt guide pulley to rotate freely on the belt guide shaft.

[0038] Adjust the position of the belt guide pulley so that its belt guide surface protrudes from the inner side of the support frame and is flush against the side of the conveyor belt of the inclined belt conveyor. This enhances the lateral restraint on the belt and effectively prevents belt deviation. After installation, check the fit between the belt guide pulley and the belt side to ensure a tight and even fit.

[0039] (4) Installation of the lower pressure roller:

[0040] Install external bearing seats on the support frame at positions corresponding to both ends of the lower pressure roller. Install the external bearing seats on the support frame at appropriate positions and secure them firmly using bolts or other connecting components.

[0041] Install both ends of the lower pressure roller into the external bearing housing, ensuring the lower pressure roller is installed horizontally and can rotate freely. After the lower pressure roller is installed, test it and check its pressure on the lower belt surface of the inclined belt conveyor to ensure that the pressure is uniform and meets the design requirements.

[0042] (5) Installation of the guard plate:

[0043] After completing the installation of all the above components, fasten the guard plate to the outside of the support frame. Ensure the guard plate fits tightly against the support frame, using bolts or other fasteners to secure it. This protects the internal components such as the pressure roller assembly, guide roller assembly, and lower pressure roller, reducing interference from dust and debris on equipment operation.

[0044] II. Commissioning and Operation of the Equipment

[0045] debug:

[0046] After the device is installed, a comprehensive commissioning process is carried out. First, check whether each component is securely installed and whether the connections are tight, ensuring that there are no loose or detached parts.

[0047] Then, manually rotate the pressure roller, guide roller, and lower pressure roller to check if their rotation is flexible and if there are any abnormalities such as jamming or friction. If any abnormalities are found, adjust and repair them promptly.

[0048] Next, start the inclined belt conveyor and let the belt run unloaded for a period of time. Observe the cooperation between the pressure pulley, guide pulley, and lower pressure roller and the belt, and check whether there are any problems such as belt deviation or jumping during operation. If any problems are found, make fine adjustments to the device according to the actual situation, such as adjusting the position of the guide pulley and the pressure of the pressure pulley, until the belt runs smoothly.

[0049] run:

[0050] After the device has been debugged and confirmed to be operating normally, the inclined belt conveyor can be put into formal operation. During operation, the device should be inspected and maintained regularly, and the wear of the pressure roller, guide roller and lower pressure roller should be observed. If any parts are severely worn, they should be replaced in time.

[0051] At the same time, pay attention to checking the protective effect of the guard plates. If there is any damage or loosening, repair and tighten them in time. Regularly clean the dust and debris inside the device to ensure a good operating environment for all components, thereby extending the service life of the device and ensuring the stable operation of the inclined belt conveyor.
