Description

Technical Field

[0001] This utility model relates to the field of explosion-proof servo motor technology, and in particular to an explosion-proof servo motor for a cleaning machine. Background Technology

[0002] In the field of industrial cleaning, especially in hazardous environments such as oil, chemical and natural gas industries where there are flammable and explosive gases or dust, the safety requirements for cleaning equipment are extremely high. As a commonly used industrial equipment, the explosion-proof performance of the core servo motor of the cleaning machine is of paramount importance.

[0003] Existing motors used in cleaning machines are susceptible to short circuits and malfunctions in harsh industrial environments, where dust, moisture, and other impurities easily penetrate the motor shaft. The lack of effective oil seals at the connection between the motor shaft and the external components makes these motors prone to short circuits and failures, failing to meet the demands of modern intelligent and sophisticated cleaning operations. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an explosion-proof servo motor for cleaning machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an explosion-proof servo motor for a cleaning machine, comprising an explosion-proof motor, a support plate provided in the upper middle part of the explosion-proof motor, a motor shaft provided at the top of the explosion-proof motor, a connecting mechanism provided at the top of the explosion-proof motor, an oil seal mechanism provided at the top of the connecting mechanism, a fixing mechanism at the bottom of the support plate, and a support mechanism at the bottom of the fixing mechanism.

[0006] Preferably, the connecting mechanism includes a first flange disposed on the top of the explosion-proof motor and a second flange disposed on the top of the first flange, a sealing gasket is provided between the first flange and the second flange, and flange bolts are provided in the disc holes of the first flange and the second flange.

[0007] Preferably, the oil seal mechanism includes an oil seal sleeve fixed to the top of the second flange and a sealing bearing disposed on the motor shaft. The oil seal sleeve is sleeved on the motor shaft, and the sealing bearing abuts against the inner top end of the oil seal sleeve. An oil filling port is provided at the top of the oil seal sleeve, and a sealing plug is inserted through the oil filling port.

[0008] Preferably, the fixing mechanism includes three fixing blocks disposed at the bottom of the support plate and a second threaded hole opened on the fixing blocks. The bottom of the support plate is provided with a fixing threaded hole corresponding to the second threaded hole, and a fixing bolt passes through the second threaded hole and the fixing threaded hole.

[0009] Preferably, the support mechanism includes three support rods disposed at the bottom of the fixed block and a crossbar disposed at the bottom of the support rods, and a connecting plate is provided between the three crossbars, the connecting plate abutting against the bottom of the explosion-proof motor.

[0010] Preferably, the support plate has first threaded holes at each of its three corners for easy connection, and the top periphery of the support plate is provided with an anti-slip pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the connection mechanism facilitates a tight and stable connection between the explosion-proof motor and external equipment, improving the sealing and reliability of the connection. This effectively prevents gas, liquid, and other media from leaking into the motor. The oil seal mechanism facilitates good sealing and lubrication of the motor shaft, improving the oil seal effect and bearing life. This reduces friction between the motor shaft and the outside, preventing dust, moisture, and other impurities from entering the motor. The support mechanism enhances the support for the motor from the bottom, improving the strength and stability of the support. This distributes the weight of the motor, reducing component deformation and damage caused by the motor's own weight. Ultimately, this solves the problem that motors are prone to short circuits and malfunctions, failing to meet the needs of modern industrial intelligent and refined cleaning operations.

[0019] 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.

[0020] Example: See Figure 1-5 This utility model discloses an explosion-proof servo motor for a cleaning machine, comprising an explosion-proof motor 1, a support plate 2 at the upper middle part of the explosion-proof motor 1, a motor shaft 3 at the top of the explosion-proof motor 1, a connecting mechanism at the top of the explosion-proof motor 1, an oil seal mechanism at the top of the connecting mechanism, a fixing mechanism at the bottom of the support plate 2, and a supporting mechanism at the bottom of the fixing mechanism. The explosion-proof motor 1 provides the power core for the entire equipment, thereby driving the cleaning machine to complete various cleaning tasks. The connecting mechanism includes a first flange 9 at the top of the explosion-proof motor 1 and a second flange 10 at the top of the first flange 9. A sealing gasket 15 is provided between the first flange 9 and the second flange 10. Flange bolts 11 are provided in the holes of the first flange 9 and the second flange 10. The first flange 9 and the second flange 10 enable the connection between the explosion-proof motor and the oil seal mechanism. The oil seal mechanism includes an oil seal sleeve 12 fixed to the top of the second flange 10 and a sealing bearing 14 set on the motor shaft 3. The oil seal sleeve 12 is sleeved on the motor shaft 3, and the sealing bearing 14 abuts against the inner top of the oil seal sleeve 12. An oil filling port is opened at the top of the oil seal sleeve 12, and a sealing plug 13 is inserted through the oil filling port. Through the arrangement of the oil seal sleeve 12, the sealing bearing 14, the oil filling port and the sealing plug 13, the connection between the motor shaft 3 and the outside can be efficiently sealed and lubricated.

[0021] In this utility model, the fixing mechanism includes three fixing blocks 7 disposed at the bottom of the support plate 2 and a second threaded hole 8 opened on the fixing block 7. The bottom of the support plate 2 has a fixing threaded hole corresponding to the second threaded hole 8. Fixing bolts are inserted into the second threaded hole 8 and the fixing threaded hole. Through the arrangement of the fixing blocks 7, the second threaded hole 8, the fixing threaded hole and the fixing bolt, the support plate 2 can be firmly installed on the explosion-proof motor, thereby providing a stable support structure for the motor and ensuring that the motor will not be displaced or loosened due to vibration or external force during operation; the support mechanism includes three fixing blocks 7 disposed at the bottom of the fixing block 7. The motor 1 has three support rods 4 and a crossbar at the bottom of the support rods 4. A connecting plate is provided between the three crossbars and abuts against the bottom of the explosion-proof motor 1. The support rods 4, crossbars and connecting plate can further enhance the support strength and stability of the motor from the bottom, thereby evenly distributing the weight of the motor. The support plate 2 has first threaded holes 6 at each of its three corners for easy connection. The top periphery of the support plate 2 is provided with anti-slip pads 5. The first threaded holes 6 can be used to easily connect other auxiliary equipment or components to the support plate 2, thereby expanding the function of the motor or achieving better collaborative work with surrounding equipment.

[0022] Working Principle: When using this invention, first connect the motor to the control system of the cleaning machine. After ensuring the electrical connection is correct, turn on the power and start the explosion-proof servo motor 1. The motor starts running and outputs power through the motor shaft 3, driving the working parts of the cleaning machine (such as cleaning brush heads, pumps, etc.) to start working. Cleaning operations are performed according to the preset program and parameters. During motor operation, the oil seal mechanism continuously seals and lubricates the motor shaft 3. The sealed bearing 14 reduces friction on the motor shaft 3, while the oil seal sleeve 12 prevents external impurities from entering, ensuring stable operation of the motor shaft 3. If the motor runs for a long time, it can be switched on as needed. Inject an appropriate amount of lubricating oil into the oil seal sleeve 12 through the oil inlet to maintain good lubrication, ensuring efficient operation and long service life of the motor. The fixing mechanism and the support mechanism work together. The fixing mechanism ensures that the support plate 2 is stably fixed on the explosion-proof motor 1, while the support mechanism provides strong support for the motor from the bottom, evenly distributing the weight of the motor and the vibration generated during operation, preventing the motor from shifting or being damaged due to vibration, and ensuring that the motor runs continuously in a stable state, improving the stability and reliability of the cleaning operation. When the cleaning task is completed, stop the operation of the explosion-proof servo motor 1 through the control system, cut off the power, and wait for the motor to stop completely.

[0023] After shutdown, inspect the motor and its components again to check for abnormal overheating, loosening, leakage, etc. If necessary, further inspect and maintain the oil seal mechanism of the motor shaft 3, such as checking the wear of the sealing bearing 14 and replacing the sealing plug 13, to ensure the motor is in good operating condition when it is started next time. Inspect and tighten the flange bolts 11 of the connecting mechanism to ensure the sealing and reliability of the connection.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
