Description

Technical Field

[0001] This utility model relates to the field of transfer equipment, and in particular to a rotor assembly transfer trolley. Background Technology

[0002] The rotor assembly is an important component of the motor, and it includes the motor shaft, iron core, permanent magnets, etc.

[0003] In actual motor assembly and production, there are many types and quantities of motor rotors, and they are frequently transferred on the production site. In addition, the motor rotors themselves have strong magnetism and are not easy to store, so there are some problems in the storage and transfer of motor rotors.

[0004] When a conventional rotor assembly is placed arbitrarily on a table, its strong magnetism causes it to adhere to the table, making it difficult to detach. Furthermore, adjacent rotors tend to stick together, making it difficult to move the rotor assembly.

[0005] In summary, how to achieve portable handling of rotor components has become an urgent problem for researchers in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is: how to achieve portable handling of rotor components;

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model relates to a rotor assembly transfer trolley, comprising: a trolley body having a horizontally mounted platform with multiple mounting holes arrayed on the platform; multiple mounting seats correspondingly installed in each of the mounting holes, each having a limiting ring and a guide ring arranged vertically and connected by a sleeve, wherein the limiting ring is located on the upper surface of the platform, the guide ring is located below the platform, the outer diameter of the limiting ring is larger than the outer diameter of the mounting hole, and the inner diameter of the guide ring is smaller than the inner diameter of the limiting ring; a support ring being vertically mounted at the mounting seat; multiple guide rods being located at the bottom of the support ring and passing through guide holes opened on the guide ring; and an elastic element being sleeved on the guide rods, its upper end abutting against the bottom of the support ring and its lower end abutting against the guide ring.

[0009] Furthermore, a cavity is provided at the inner ring of the mounting base, so that when the support ring moves to the lower limit position, the upper surfaces of the support ring and the limiting ring are flush.

[0010] Furthermore, a groove is radially formed on one side of the support ring.

[0011] Furthermore, the mounting base, support ring, guide rod, and elastic element are all made of non-magnetic materials.

[0012] Furthermore, the bottom of the vehicle body is equipped with omnidirectional wheels for easy movement.

[0013] Furthermore, a handrail is provided on one side of the vehicle body to facilitate pushing and walking.

[0014] The beneficial effects of this utility model are as follows: This utility model is a rotor assembly transfer trolley. When a rotor assembly needs to be placed, the rotor assembly is placed vertically, and one end of the motor shaft is inserted into the support ring. The support ring descends to its lower limit position, and the elastic element is in a compressed state. The support ring and the limiting ring work together on the shoulder of the motor shaft, which facilitates the simultaneous and stable transfer of multiple rotor assemblies. When a rotor assembly needs to be removed, the operator holds the top of the motor shaft with one hand and moves it upward. The support ring moves upward with it, and the elastic element restores its elasticity and acts on the support ring, giving the rotor assembly a certain upward support force, reducing the lifting force required by the operator with one hand. When the bottom of the motor shaft is completely detached from the limiting ring, the operator holds the bottom of the motor shaft with the other hand and pulls the rotor assembly out from the side of the slot, separating the rotor assembly from the transfer trolley.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Figure 1This is a structural schematic diagram of the transfer trolley; the transfer trolley includes a car body 1, and the loading platform 2 of the car body 1 is provided with mounting holes. Each mounting hole is equipped with a mounting seat 3. The motor shaft of the rotor assembly 01 is vertically arranged, and one end of the motor shaft is inserted into the mounting seat 3. The transfer trolley can transport 12 rotor assemblies 01 at a time.

[0023] The bottom of the vehicle body 1 is equipped with casters 4, and a handrail 5 is provided on one side of the vehicle body 1. The operator can hold the handrail 5 and push the vehicle body 1 to the location where it needs to be transferred.

[0024] Figure 2 This is a schematic diagram of the mounting base 3 and the support ring 6 set inside the mounting base 3. In the figure, the mounting base 3 is set from top to bottom as a limiting ring 31, a sleeve 32, and a guide ring 33. The outer diameter of the limiting ring 31 is larger than the outer diameter of the mounting hole, so that the mounting base 3 can be hoisted at the mounting hole. The purpose of setting the guide ring 33 is to facilitate the passage of the guide rod 7.

[0025] The support ring 6 is lifted and installed in the mounting base. A guide rod 7 is provided at the bottom of the support ring 6. An elastic element 8 is provided between the support ring 6 and the guide ring 7. The elastic element 8 can be made of non-magnetic core materials such as copper alloy and titanium alloy. A groove 61 is radially opened on one side of the support ring 6. By providing the groove 61, one end of the bottom of the rotor assembly 01 can be moved laterally to the outside of the support ring 6, so as to separate the rotor assembly 01 from the transfer trolley.

[0026] Figure 3 The diagram shows a cross-sectional view of the support ring at its lower limit position. At this point, due to the gravity of the rotor assembly 01, the support ring 6 is located within the cavity 34 opened by the limiting ring 33, the elastic element 8 is in a compressed state, and the upper surface of the support ring 6 is flush with the upper surface of the limiting ring 31. The support ring 6 and the limiting ring 31 work together on the bottom of the rotor assembly 01, increasing the contact area between the rotor assembly 01 and the support ring 6 and the limiting ring 31, making the rotor assembly 01 more stable during transportation. In addition, the limiting ring 31 can restrict the support ring 6 from moving further downward.

[0027] Figure 4 The diagram shows a cross-sectional view of the support ring at its upper limit position. At this point, the rotor assembly 01 is separated from the transfer trolley, and the elastic element 8 releases its elastic force, causing the support ring 6 to disengage from the cavity 34 of the limiting ring 31.

[0028] Working principle: When rotor assembly 01 needs to be placed, it is placed vertically, and the bottom end of the motor shaft is inserted into the support ring 6. The support ring 6 descends to its lower limit position under the influence of gravity, and the elastic element 8 is in a compressed state. The support ring 6 and the limiting ring 31 work together on the shoulder of the motor shaft, which facilitates the simultaneous and stable transfer of multiple rotor assemblies 01. When rotor assembly 01 needs to be removed, the operator holds the top of the motor shaft with one hand and moves it upward. The support ring 6 moves upward with it, and the elastic element 8 restores its elasticity and acts on the support ring 6, giving the rotor assembly 01 a certain upward support force, reducing the lifting force of the operator's single hand. When the bottom of the motor shaft is completely separated from the limiting ring 31, the operator holds the bottom of the motor shaft with the other hand and pulls the rotor assembly 01 out from the side of the slot 61, separating the rotor assembly 01 from the transfer trolley. This achieves efficient transfer of the rotor assembly 01 and avoids damage to the rotor assembly 01 or mutual adsorption.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
