Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof motors, in particular to an assembly structure of explosion-proof motors. Background Art

[0002] Explosion-proof motors are motors that can be used in flammable and explosive places and do not generate sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, they are also widely used in textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other sectors. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.

[0003] The Chinese patent with announcement number CN220492837U discloses an assembly structure of an explosion-proof motor, including an explosion-proof motor, a bottom plate, four fixing blocks, two device shells, a control block, two bases and a limit device. By setting the limit device, the limit block, the extrusion block, the spring, the T-shaped slider and the T-shaped slide frame, the problem that the existing explosion-proof motor needs to clean the condensed water and dirt in the junction box before connecting the cable during installation is solved, and attention should be paid to whether the electrical clearance in the junction box meets the requirements. Usually, the explosion-proof motor is directly installed on the surface of the equipment by bolt installation. When the explosion-proof motor needs to be disassembled for maintenance or replacement, it is necessary to continuously rotate multiple bolts to the appropriate position. This disassembly and assembly method takes a long time and is not convenient enough. The threaded hole surface of the equipment surface is easily damaged by multiple disassembly and installation bolts, which eventually leads to unstable installation of the explosion-proof motor. However, the existing explosion-proof motor has no components for convenient disassembly and assembly.

[0004] The assembly structure of the explosion-proof motor described above pulls the control block when disassembling the explosion-proof motor. When the control block moves, it drives the T-shaped slider to move in the inner cavity of the T-shaped slide frame. When the control block moves, the extrusion force generated on the extrusion rotating frame will drive the two extrusion rotating frames to rotate along the surface of the extrusion block through the rotating shaft. When the two extrusion blocks are subjected to the extrusion force of the extrusion rotating frame, they will move closer to each other. When the extrusion block moves, it will drive the two limit blocks to move closer to each other. When the limit block moves, it will drive the stabilizing shell to move along the surface of the stabilizing block. When the stabilizing shell moves, the force generated causes the spring to bounce. The device shell is placed in a position in contact with the surface of the fixed block when the device shell moves. The explosion-proof motor and the base are driven to move to the top of the bottom plate when the device shell moves. Then the control block is released, and the restoring force generated by the spring restoring its shape drives the limit block to be inserted into the inner cavity of the limit groove. The limit block and the limit groove are used in coordination to limit the position of the device shell and the explosion-proof motor. There are many structures involved in the installation and disassembly of the explosion-proof motor, and the coordination between the various structures is relatively complicated, which makes the installation structure of the explosion-proof motor relatively complicated and the investment cost is relatively high.

[0007] Optionally, the pressing block includes a movable plate, a clamping plate is fixed to both the front and rear ends of the movable plate, and a pressing plate is fixed to the side of the movable plate facing the support seat.

[0008] Optionally, a plurality of limiting columns are fixed to a side of the movable plate facing the spring, and the limiting columns are inserted into the inner side of the spring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
