Description

Technical Field

[0001] This utility model relates to the field of crane motor technology. More specifically, it relates to a crane motor wind cap and a crane motor. Background Technology

[0002] In the field of lifting machinery, a manual cranking operation is required before starting the motor. This involves manually rotating the motor shaft to check the smoothness of the internal mechanical structure and prevent jamming that could cause equipment malfunction. Currently, the commonly used lifting motor wind cap structure (such as...) Figure 1 As shown, there is a risk of inadequate protection. Traditional wind caps have a through-hole hollow channel (101) in the center to allow the motor shaft to pass through, which facilitates the connection between the crank handle and the motor shaft for turning operation. However, due to the existence of this channel, the motor shaft is still exposed after the motor is started. The exposed motor shaft is very likely to cause the operator's limbs or clothing to be caught in it, resulting in serious mechanical injury accidents. Utility Model Content

[0003] In view of the above problems, one objective of this utility model is to provide a safe, reliable and easy-to-operate hoist motor wind cap.

[0004] Another objective of this invention is to provide a crane motor including a crane motor wind cap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] According to one aspect of the present invention, a hoisting motor wind cap is provided, comprising:

[0007] The hood base, sleeve, and blind flange;

[0008] The wind cap base includes a wind cap wall with a cylindrical structure, and a mesh plate fixed to one end of the wind cap wall;

[0009] The sleeve is open at both ends, and one end is fixed to the side of the mesh plate away from the wind cap wall, communicating with the inside of the wind cap wall. The inside of the sleeve forms a space to accommodate the motor shaft.

[0010] Wherein, the axial length of the sleeve is greater than the axial length of the motor shaft exposed outside the wind cap base;

[0011] The blind flange is detachably fixed to the side of the sleeve away from the wind cap base, sealing the opening at the other end of the sleeve.

[0012] Alternatively, the sleeve can be a stainless steel cylindrical structure with an inner diameter larger than the diameter of the motor shaft and smaller than the outer diameter of the wind cap wall.

[0013] Alternatively, the mesh panel can be circular with a through hole in the center, and the sleeve can be fixed to the through hole and connected to the interior of the wind cap wall through the through hole.

[0014] The diameter of the through hole is less than or equal to the inner diameter of the sleeve.

[0015] Alternatively, the connecting side of the sleeve and the mesh plate includes an annular welded portion, which is continuously welded to the side of the mesh plate away from the wind cap wall by argon arc welding.

[0016] Alternatively, the blind flange can be detachably fixed to the sleeve by a clamp, the clamp comprising two C-shaped rings and a fastening bolt, one end of the two C-shaped rings being hinged and the other end being detachably connected by the fastening bolt;

[0017] Two C-shaped clamps are fitted onto the connection between the blind plate and the sleeve, and are tightened by fastening bolts to connect the blind plate and the sleeve.

[0018] Alternatively, the inner wall of the C-shaped hoop may include a first groove and a second groove arranged along the axial direction.

[0019] Alternatively, the blind plate can be a circular steel plate with radial flanges along its edges.

[0020] The radial flange is engaged within the first groove.

[0021] Alternatively, an annular connecting portion may be provided at one end of the sleeve away from the hood base;

[0022] The annular connecting part is engaged in the second groove.

[0023] Alternatively, the wind cap base, sleeve, and blind plate can be arranged coaxially.

[0025] The motor shaft of the motor assembly passes through the sleeve.

[0026] The beneficial effects of this utility model are as follows:

[0027] To address the technical problems existing in the prior art, this utility model provides a hoist motor wind cap and a hoist motor. Through the coordinated structural design of the wind cap base, sleeve, and blind flange, a fully enclosed rigid protection for the motor shaft is achieved, with an impact resistance strength of over 50J.

[0038] To address the shortcomings of existing technologies, this utility model provides a hoisting motor wind cap, combined with... Figure 2-5 As shown, the hoist motor wind cap includes a wind cap base 1, a sleeve 2, and a blind plate 3.

[0039] The hood base 1 includes a hood wall 11 with a cylindrical structure, and a mesh plate 12 attached to one end of the hood wall 11.

[0040] The sleeve 2 has openings at both ends, with one end fixed to the side of the mesh plate 12 away from the wind cap wall 11, communicating with the inside of the wind cap wall 11. The inside of the sleeve 2 forms a space to accommodate the motor shaft 200.

[0041] The axial length of the sleeve 2 is greater than the axial length of the motor shaft 200 exposed outside the wind cap base 11.

[0042] The blind flange 3 is detachably fixed to the side of the sleeve 2 away from the wind cap base 1, sealing the opening at the other end of the sleeve 2, so as to encapsulate the electrode shaft 200 inside the sleeve 2 and avoid the safety hazard caused by the motor shaft coming into contact with the operator during the operation of the crane motor.

[0043] In one specific embodiment, the sleeve 2 is a stainless steel cylindrical structure with an inner diameter larger than the diameter of the electrode shaft 200 and smaller than the outer diameter of the wind cap wall 11, so that the crank can enter the sleeve 2 and connect with the motor shaft 200 located in the sleeve 2 for cranking operation.

[0044] In a preferred example, the gap between the inner wall of the sleeve 2 and the outer wall of the motor shaft 200 is greater than or equal to 15 mm.

[0045] In one embodiment, the mesh plate 12 has a circular structure and is mesh-like, generally made of metal mesh or a perforated plate, and is welded and fixed to the wind cap wall 11. The porous structure of the mesh plate 12 can intercept dust, fibers, insects, debris and other impurities in the air, preventing them from entering the equipment (such as motor windings and fan blades), preventing poor heat dissipation, mechanical jamming or short circuit risks caused by the accumulation of foreign objects, and can achieve protection even with air circulation, avoiding a decrease in heat dissipation efficiency due to complete enclosure.

[0046] A through hole 121 is provided in the center of the mesh panel 12, and the sleeve 2 is fixed at the through hole 121, communicating with the interior of the wind cap wall 11 through the through hole 121. The diameter of the through hole 121 is less than or equal to the inner diameter of the sleeve 2.

[0047] In a specific embodiment, such as Figure 4 As shown, the connection side between the sleeve 2 and the mesh plate 12 includes an annular welded part 21, which is continuously welded to the side of the mesh plate 12 away from the wind cap wall 11 by argon arc welding.

[0048] In one embodiment, the blind flange 3 is detachably fixed to the sleeve 2 by a clamp 4. Specifically, the clamp 4 includes two C-shaped rings 41 and a fastening bolt 42. One end of the two C-shaped rings 41 is hinged, and the other end is detachably connected by the fastening bolt 42.

[0049] Two C-shaped clamps are fitted at the connection between the blind plate 3 and the sleeve 2 and are locked by fastening bolts 42. The clamps radially compress the blind plate 3 and the sleeve 2 to achieve the connection between the blind plate 3 and the sleeve 2. This design has the advantages of simple structure, convenient installation and disassembly.

[0050] In one specific embodiment, the inner wall of the C-shaped clamp 41 includes a first groove 411 and a second groove 412 arranged along the axial direction for positioning and limiting during clamp installation to prevent displacement.

[0051] In one embodiment, such as Figure 5 As shown, the blind plate 3 is a circular steel plate with a radial flange 31 on its edge. When the blind plate 3 and the sleeve 2 are connected by the clamp 4, the radial flange 31 is engaged in the first groove 411.

[0052] Furthermore, the blind plate 3 is preferably a circular mesh steel plate, which is a mesh structure formed by stamping steel plate or stainless steel wire weaving, which can play a heat dissipation role and prevent overheating inside the motor.

[0053] In one embodiment, such as Figure 4 As shown, the end of the sleeve 2 away from the wind cap base 1 is provided with a connecting ring 22. When the blind plate 3 and the sleeve 2 are connected by the clamp 4, the connecting ring 22 is engaged in the second groove 412.

[0054] In this embodiment, the hood base 1, sleeve 2, blind plate 3, and clamp 4 are all coaxially arranged and all are made of rust-proof metal.

[0055] The hoisting hood provided in this embodiment is installed on the hoisting motor. When the hoisting motor needs to be rotated, first remove the clamp 4 to separate the blind flange 3 from the sleeve 2. Then, the crank handle is inserted into the sleeve 2 and connected to the motor shaft 200 for rotation. After the rotation is completed, the blind flange 3 is reinstalled on the sleeve 2 using the clamp 4, and finally the hoisting motor is started. This greatly improves the safety of the hoisting motor during operation.

[0056] In a specific example, the axial length of sleeve 2 = axial length of motor shaft + 50mm.

[0057] Another embodiment of this utility model provides a lifting motor, which includes the motor wind cap provided in the above embodiment, and a motor assembly disposed within the wind cap wall. The motor shaft of the motor assembly passes through the sleeve 2.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
