Description

Technical Field

[0001] The utility model relates to the technical field of protective covers, in particular to an openable protective cover for a motor coupling. Background Art

[0002] Couplings are important devices in mechanical engineering, used to connect two shafts or shafts and rotating parts, ensuring that they rotate together and are not easily disengaged during the transmission of motion and power. Couplings can compensate for the offset between the two shafts caused by manufacturing and installation errors, working deformation or thermal expansion, including axial, radial and angular offsets, thereby ensuring the smoothness of transmission. Secondly, some couplings contain elastic elements that can buffer and reduce vibration, protecting the transmission system from the impact of impact loads.

[0003] As an important part of the pump, the motor coupling needs to be effectively protected to prevent personnel from mechanical injuries and irreparable losses. The existing motor coupling protective cover is usually a closed structure. Although it can play a certain protective role, it is cumbersome to disassemble when observing, monitoring, maintaining and repairing the coupling, and it is impossible to detect abnormal conditions of the coupling in time, such as looseness, excessive wear, etc., which can easily lead to motor failure and affect production and use. In many cases, in order to speed up the maintenance progress, the protective cover is forcibly opened when the equipment is not stopped, which is prone to mechanical injury accidents. For this reason, an openable motor coupling protective cover is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for an openable motor coupling protective cover, including a protective cover body 1, a positioning base 2 is provided at the bottom of the protective cover body 1, a positioning through hole 3 is opened on the positioning base 2, an inspection port 4 is opened at the upper end of the protective cover body 1, a cover body assembly 6 is provided in the inspection port 4, the cover body assembly 6 includes a protective cover cover 601 movably mounted on the protective cover body 1, a sensor 5 is provided at the edge of the protective cover cover 601, and a limiting mechanism 7 is fixedly installed on the front surface of the protective cover body 1. The coordinated use of the electromagnet 605 and the limiting mechanism 7 can prevent the user from opening the protective cover cover 601 when the motor is started, thereby improving the safety of use.

[0022] like Figure 2 and Figure 3 As shown, the cover body assembly 6 includes a protective cover cover 601 movably mounted on the protective cover body 1, a net port 602 is provided on the protective cover cover 601, a protective net 603 is provided in the net port 602, a positioning foot 606 is fixedly mounted on one side of the protective cover cover 601, a limiting slot 604 is provided at the end of the positioning foot 606, an electromagnet 605 is connected in the limiting slot 604, a sensor 5 is provided at the edge of the protective cover cover 601, and the cover body assembly 6 also includes a hinge 607 arranged on the protective cover cover 601, and the protective cover cover 601 is movably mounted on the protective cover body 1 through the hinge 607.

[0023] Specifically, the compression spring 707 will push the iron latch 705 into the limit slot 604, and the power supply of the electromagnet 605 is interlocked with the power supply of the motor. When the motor starts, the electromagnet 605 will absorb the iron latch 705, so that the iron latch 705 cannot be pulled out of the limit slot 604, preventing the user from opening the protective cover 601 when the motor is working, and when the protective cover 601 is opened, the sensor 5 can control the alarm to sound, further preventing the user from opening the protective cover 601 when the motor starts.

[0024] like Figure 2 and Figure 4 As shown, the limiting mechanism 7 includes a limiting seat 701 fixed on the front surface of the protective cover body 1, a winding disk 702 is movably installed in the middle position of the limiting seat 701, and a steel wire rope 704 is connected to the winding disk 702. Spring seats 706 are movably installed at the edges of both ends of the limiting seat 701, an iron latch 705 is fixedly installed on the spring seat 706, a compression spring 707 is provided on one side of the spring seat 706, and a knob 703 is connected to the winding disk 702.

[0025] Specifically, after turning the knob 703, it will drive the winding disk 702 to rotate, and after the winding disk 702 rotates, it will reel in the wire rope 704. After the wire rope 704 is reeled in, it will pull the spring seat 706 to contract, thereby driving the iron latch 705 to disengage from the limit slot 604, making it convenient for the user to open the protective cover 601 and facilitate the user to perform maintenance and repair.

[0026] Working principle: When in use, the protective cover 601 can be covered, and the knob 703 can be loosened after covering the protective cover 601. After loosening the knob 703, the compression spring 707 will push the spring seat 706 to move forward. After the spring seat 706 moves forward, it will drive the iron latch 705 to move forward. The forward movement of the iron latch 705 will be embedded in the limit slot 604, thereby fixing the protective cover 601. The power supply of the electromagnet 605 is interlocked with the power supply of the motor. When the motor is started, the electromagnet 605 will absorb the iron latch 705, so that the iron latch 705 cannot be pulled out of the limit slot 604, preventing the user from opening the protective cover 601 when the motor is working. An alarm and a controller are installed within 3 meters around the motor equipment. The controller is respectively connected to the sensor 5 and the alarm to receive the signal of the sensor 5. The alarm power supply is interlocked with the motor power supply. The motor power supply is interlocked, and the coupling protective cover cover 601 opens when the motor is running. The sensor 5 can control the alarm to sound. When the motor is powered off, the coupling protective cover cover 601 opens without triggering an alarm, further preventing the user from opening the protective cover cover 601 when the motor is started. At the same time, after the motor is turned off, the power supply of the electromagnet 605 will also be disconnected. After the power supply of the electromagnet 605 is disconnected, the knob 703 can be turned. After turning the knob 703, it will drive the winding disk 702 to rotate. After the winding disk 702 rotates, it will reel in the wire rope 704. After the wire rope 704 is reeled in, it will pull the spring seat 706 to contract. After the spring seat 706 contracts, it will drive the iron latch 705 to disengage from the limit slot 604. After the iron latch 705 disengages from the limit slot 604, the protective cover cover 601 can be opened, which is convenient for users to perform maintenance and overhaul.
