Description

Technical Field

[0001] This utility model relates to the field of safety protection for chemical machinery, and in particular to a coupling protective cover for chemical centrifugal pumps. Background Technology

[0002] Coupling covers are crucial safety components for chemical pumps and other equipment with coupling transmissions, and their performance directly impacts equipment operation safety and personnel safety. Currently, most coupling covers on the market are not fully enclosed, resulting in excessive radial clearance at the pump and motor ends, exposing rotating parts and posing a significant risk of mechanical injury and other accidents. Furthermore, existing coupling cover frames have simple structures, often directly welded to the machine base. This leads to insufficient overall rigidity and poor load-bearing capacity, causing instability such as shaking and damage during equipment operation. Disassembly and maintenance are also difficult, requiring substantial time and manpower. Additionally, the lack of visual monitoring design makes it difficult to monitor the coupling's operating status in real time, failing to meet the stringent requirements of the chemical industry for safe, efficient, and intelligent equipment operation. Therefore, developing a new type of fully enclosed coupling protection device to solve these technical challenges is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a coupling protective cover for chemical centrifugal pumps, which solves the problems of existing coupling covers such as non-enclosed structure, exposed rotating parts, insufficient rigidity, poor pressure bearing capacity, difficulty in disassembly and maintenance, and inability to be visually monitored.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a coupling protective cover for a chemical centrifugal pump, comprising: The cover has a motor end lower side plate and a pump end lower side plate fixedly connected to it. A motor end upper side plate is fixedly connected to the motor end lower side plate, and a pump end upper side plate is fixedly connected to the pump end lower side plate. The motor end lower side plate and the pump end lower side plate are arranged opposite to each other. A top cover is rotatably connected to the cover. Four brackets are fixedly connected to the cover. The brackets are provided with adjustable feet. A first through hole is opened on the motor end lower side plate and the motor end upper side plate. A second through hole is opened on the pump end lower side plate and the pump end upper side plate. Several heat dissipation holes are opened on the cover.

[0005] Preferably, the upper cover and the cover are rotatably connected by a hinge, and the hinge is fixedly connected to the upper cover and the cover by rivets.

[0006] Preferably, the bracket has a mounting hole, the adjustable leg has an elongated hole, a bolt is inserted into the mounting hole and the elongated hole, and a nut is threaded onto the bolt.

[0007] Preferably, a connecting plate one is fixedly connected to the upper cover, and a connecting plate two is fixedly connected to the cover body. Both the connecting plate one and the connecting plate two have through holes, and a bolt two is inserted into the through hole. The bolt two is threaded with a nut two.

[0008] Preferably, a handle is fixedly connected to the upper cover.

[0009] The present invention discloses the following technical effects: Fully enclosed protection and visual monitoring: The combination design of the upper and lower side plates of the pump end, the upper and lower side plates of the motor end, and the cover achieves a four-sided fully enclosed structure, which can adapt to the installation environment with small gaps with the left and right equipment. This structure not only effectively eliminates the risk of exposed rotating parts and greatly improves the safety of on-site equipment operation, but also has waterproof and dustproof functions. At the same time, the observation holes of the cover enable visual monitoring of rotating parts, which facilitates real-time monitoring of equipment operation status and provides dual protection for safe equipment operation.

[0010] High rigidity and strong load-bearing capacity: The robust support of the bracket significantly enhances the overall structural rigidity, fully meeting the load-bearing requirements of relevant standards for coupling covers. Even under a certain range of external load impacts, it effectively prevents the protective device from contacting rotating parts, ensuring stable equipment operation and extending equipment service life.

[0011] Convenient maintenance design: The top cover and the housing are easily opened and closed using bolts and nuts, making operation simple and effortless. Routine maintenance tasks such as inspection and rotation can be easily performed without disassembling the protective device, greatly improving equipment maintenance efficiency and reducing downtime and repair costs.

[0012] Flexible installation and adjustment: The bracket adopts a connection method of bolts and adjustable feet, which can flexibly adjust the height and position of the device according to different installation environments and equipment requirements. This not only significantly improves the convenience of installation, but also optimizes the rationality of installation and enhances the versatility and adaptability of the device.

[0013] This utility model, with its innovative structural design and functional integration, successfully solves many problems existing in the coupling cover, such as non-enclosed structure, exposed rotating parts, insufficient rigidity, poor pressure bearing capacity, difficult disassembly, inconvenient equipment maintenance, and lack of visual monitoring. It provides a safer, more efficient, and reliable solution for the protection of chemical centrifugal pump couplings. Attached Figure Description
