Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic braking motors, in particular to an electromagnetic braking motor. Background Art

[0002] Motors are widely used in people's daily lives, providing great convenience to human life, including electromagnetic braking motors. When the braking motor is connected to the power supply, the brake also works simultaneously. Due to the electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, the brake disc disengages from the armature end cover, and the motor starts to operate.

[0003] In the process of using the existing electromagnetic braking motor, after the stator and rotor in the motor are energized to generate magnetism, the rotor rotates. During the rotation process, due to the existence of magnetism, a large amount of heat is generated inside the motor. These heats are dissipated outward through the motor housing, and the dissipated heats are prone to accumulate on the outside of the motor and have slow fluidity. Therefore, the heat dissipation efficiency of the motor is reduced. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an electromagnetic braking motor.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] An electromagnetic braking motor includes a motor. A main shaft is installed in the middle of one end of the motor. An eccentric plate is fixed on the outside of the main shaft. Extrusion components are symmetrically arranged on both sides of the eccentric plate. The extrusion component includes a support plate fixed on the motor. A contact plate is arranged on one side of the support plate adjacent to the main shaft. A connecting rod is installed at one end of the contact plate in a pair, and the connecting rod penetrates through one end of the support plate and is installed with an extrusion plate. A return spring is installed between the extrusion plate and the support plate. An airbag is arranged on the side of the extrusion plate away from the support plate, and a plurality of exhaust holes are opened on the motor corresponding to the airbag.

[0007] Preferably, an intake valve is installed in the middle of the top of the airbag, and the intake valve is a one-way intake mechanism.

[0008] Preferably, a plurality of heat dissipation fins are installed in the middle of the motor, and a heat dissipation hole is opened at one end of the motor away from the main shaft.

[0009] Preferably, a mounting seat is fixed in the middle of the bottom end of the motor, and a lifting ring is connected to the mounting seat by a thread.

[0010] Preferably, fixing holes are opened at the four corners on the side of the motor close to the main shaft.

[0011] Preferably, a controller is installed in the middle of one side of the motor, and electrical components for controlling the operation of the motor are provided inside the controller.

[0012] The beneficial technical effects are as follows:

[0013] By providing an eccentric plate, an extrusion assembly, an airbag and exhaust holes, the eccentric plate can be driven to rotate during the rotation of the main shaft. The eccentric plate can intermittently contact the extrusion assemblies on both sides. After the contact plate in the extrusion assembly contacts the eccentric plate, the extrusion plate is driven to extrude the airbag through a connecting rod. The gas generated by the airbag after extrusion is blown towards the periphery of the motor through the exhaust holes, thereby dissipating the heat around the motor and improving the heat dissipation efficiency of the motor. Moreover, after the eccentric plate separates from one of the extrusion assemblies, the extrusion plate and the contact plate are reset by a return spring. Description of the Drawings

[0019] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below with reference to the embodiments and the drawings. However, the embodiments of the present invention are not limited thereto.

[0020] As Figures 1 - 3As shown in the figure, an electromagnetic braking motor provided in this embodiment includes a motor 1. In the middle of one end of the motor 1, a main shaft 2 is installed. The main shaft 2 can drive external equipment to rotate. An eccentric plate 3 is fixed on the outside of the main shaft 2. The eccentric plate 3 can intermittently contact the extrusion components 4 on both sides. The extrusion components 4 are symmetrically arranged on both sides of the eccentric plate 3. The extrusion component 4 includes a support plate 401 fixed on the motor 1. The support plate 401 can support the contact plate 402 and the guide rod. On one side of the support plate 401 adjacent to the main shaft 2, there is a contact plate 402. At one end of the contact plate 402, a connecting rod 403 is installed. And the connecting rod 403 penetrates through one end of the support plate 401 and is installed with an extrusion plate 404. After the contact plate 402 contacts the eccentric plate 3, the extrusion plate 404 is driven by the connecting rod 403 to extrude an airbag 5. A return spring 405 is installed between the extrusion plate 404 and the support plate 401. After the eccentric plate 3 separates from one of the extrusion components 4 on one side, the extrusion plate 404 and the contact plate 402 are driven by the return spring 405 to reset. On the side of the extrusion plate 404 away from the support plate 401, there is an airbag 5. And on the motor 1, a plurality of exhaust holes 7 are opened corresponding to the airbag 5. The gas generated by the airbag 5 is blown around the motor 1 through the exhaust holes 7, thereby dissipating the heat around the motor 1.

[0021] As Figures 1 - 3 shown, in the middle of the top end of the airbag 5, an air inlet valve 6 is installed, which can ensure the normal air intake of the airbag 5 through the air inlet valve 6. The air inlet valve 6 is a one-way air intake mechanism.

[0022] As Figures 1 - 2 shown, on the middle part of the motor 1, a plurality of heat dissipation fins 8 are installed. And on one end of the motor 1 away from the main shaft 2, a heat dissipation hole 9 is opened, which is convenient for the heat inside the motor 1 to be dissipated to the outside through the heat dissipation fins 8 and the heat dissipation hole 9.

[0023] As Figures 1 - 2 shown, in the middle of the bottom end of the motor 1, a mounting seat 10 is fixed. And on the mounting seat 10, a lifting ring 11 is connected by a thread, which is convenient for the lifting ring 11 to be connected to the motor 1 through the mounting seat 10. An external lifting device then hoists the motor 1 through the lifting ring 11.

[0024] As Figures 1 - 2 shown, at the four corners on one side of the motor 1 close to the main shaft 2, fixing holes 12 are opened, which is convenient for workers to install the motor 1 by using bolts through the fixing holes 12.

[0025] As Figures 1 - 2 shown, on one side of the middle part of the motor 1, a controller 13 is installed. And inside the controller 13, there are electrical components for controlling the operation of the motor 1, which can connect an external power supply to the controller 13 and then control the operation of the motor 1.

[0026] Working principle of this device: When this device is in specific use, the lifting ring 11 is connected to the motor 1 through the mounting base 10, and an external lifting device hoists the motor 1 through the lifting ring 11. After hoisting to the installation position, the staff installs the motor 1 with bolts through the fixing holes 12 and connects the external power supply to the controller 13, and then controls the motor 1 to work. During the working process of the motor 1, the main shaft 2 drives the external device to rotate. At the same time, during the rotation of the main shaft 2, the eccentric plate 3 is driven to rotate. The eccentric plate 3 can intermittently contact the extrusion components 4 on both sides. After the contact plate 402 in the extrusion component 4 contacts the eccentric plate 3, the extrusion plate 404 is driven by the connecting rod 403 to extrude the airbag 5. The gas generated by the airbag 5 after extrusion blows towards the periphery of the motor 1 through the exhaust holes 7, thereby dispersing the heat around the motor 1 and improving the heat dissipation efficiency of the motor 1. And after the eccentric plate 3 separates from one of the extrusion components 4, the extrusion plate 404 and the contact plate 402 are driven by the return spring 405 to reset.

[0027] The above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, all belong to the protection scope of the present utility model.
