Description

Technical Field

[0001] The present invention relates to a sling, in particular to a motor base sling. Background Art

[0002] During the motor manufacturing process, the motor base needs to be transferred to multiple processing stations multiple times. Furthermore, the base needs to be adjusted between processing stations, requiring horizontal bases to be transported or vertical bases to be lifted. Consequently, motor manufacturers' production workshops require a wide variety of lifting equipment of varying specifications.

[0003] For example, in the utility model patent document entitled "A Motor Base Hanger" (CN 204355962 U), the disclosed hanger comprises a first hanger plate 31 and a second hanger plate 32. The first hanger plate 31 and the second hanger plate 32 are made of elastic steel plates. The upper ends of the first hanger plate and the second hanger plate are hinged together in parallel via a U-shaped ring 2. The upper middle parts of the first and second hanger plates are twisted 90° and the plate surfaces below the twisted position are opposite to each other. The two hangers have hooks at their lower ends for hooking workpieces. A first connecting rod 310 is also hinged on the first hanger plate. A plurality of limiting grooves 3101 are arranged along the length direction of the first connecting rod 310. A second connecting rod 320 is also hinged on the second hanger plate. A locking pin 3201 is provided at the other end of the second connecting rod 320 away from the hinged end. The locking pin and the limiting groove match each other and can achieve blocking cooperation. The above solution provides two lifting points, which are suitable for lifting the machine base in a horizontal posture, that is, the two bent portions 30 are correspondingly hooked on the heat dissipation fins on opposite sides of the horizontal machine base for lifting.

[0004] The name is "motor base hanger" (CN 212953855 U). The bottom of the hanger 2 is fixedly connected to a positioning block 3, the top of the hanger 2 is fixedly connected to a lifting ear 4, the outside of the hanger 2 is provided with a protrusion 5, the internal thread of the protrusion 5 is connected to a screw 6, one end of the screw 6 is fixedly connected to a clamping sleeve 7, the outside of the motor base 1 is fixedly connected to a fixed lifting point 8, and the inside of the motor base 1 is fixedly connected to a protruding round table 9. Although the above technical solution can lift a vertically arranged motor base, it requires a junction box on the outside of the base to be used as a force fulcrum, and the other force-bearing part is the inner wall of the base. For a base with a processed inner wall, it is obviously inappropriate to use the inner wall as a force fulcrum. Moreover, since the internal and external force-bearing parts are concentrated on one side of the base, if the base is too large or too heavy, it may cause damage to the base. In addition, when lifting, the screw 6 needs to be adjusted to make the sleeve 7 support the protruding round table 9 fixedly connected to the inside of the motor base 1, which seriously affects the lifting efficiency.

[0005] In the invention patent document entitled "Lifting device for motor base" (CN 105502152 A), the two ends of the cross bar 10 are respectively clamped in the ports of the ventilation duct 21 arranged on the inner wall of the base 20 near the port, so as to support the base 20 and complete the transfer of the base 20. Of course, in actual processing, it is necessary to ensure that the rod length d2 of the cross bar 10 is between the inner side spacing D1 and the outer side spacing D2 of the two corresponding ventilation ducts 21. Figure 5 As shown; for the machine base 20 with its axis in the horizontal direction, the transfer ring 22 on the machine base 20 can be hung by the hook 12 at the lower part of the crossbar 10. When implementing horizontal machine base lifting, this solution requires the motor base to have a transfer ring 22, and when implementing vertical machine base lifting, the machine base needs to have ports of ventilation duct 21 that form a support with the two ends of the crossbar 10.

[0006] It can be seen that the slings in the prior art have various limitations. They can only be used to lift horizontal or vertical machine bases. Slings that are barely applicable to lifting horizontal and vertical machine bases are strictly restricted by the structure of the machine base. Summary of the Invention

[0007] The purpose of the present invention is to provide a motor base lifting device, which can realize the lifting of vertical and horizontal motor bases by connecting ear seats and heat dissipation fins on the end faces of the motor base.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0009] A motor base hanger, characterized in that: the upper ends of the first, second and third hangers are hingedly connected at the edge of the top base by a horizontally arranged first hinge axis, a second hinge axis and a third hinge axis; the lower ends of the first, second and third hangers have a first hook, a second hook and a third hook bent inward; and when the first hook, the second hook and the third hook are at the same height, the relative positions of the first hook, the second hook and the third hook coincide with the corresponding positions of the end cover connecting seats on the motor base.

[0010] The top seat is hingedly connected to the upper ends of the first, second and third hangers by the horizontally arranged first hinge axis, second hinge axis and third hinge axis, and the lower end of each hanger is provided with a hook bent inward. When the first, second and third hangers are swung around the hinge axis at their upper ends, the positions of the hooks at the lower ends can be adjusted to match the positions of the end cover connecting seats 2 on the motor base, so as to be hooked on the lower end surface of the end cover connecting seat to lift the vertically arranged motor base; the first, second and third hangers are also swung to adjust the spacing between the first, second and third hooks, so that the first, second and third hooks are separately placed and hooked on the heat sinks at corresponding positions on both sides of the horizontally arranged motor base to lift the horizontally arranged motor base.

[0011] The technical effect of the present invention is mainly reflected in that it can lift a motor base arranged horizontally or a motor base arranged vertically, thus achieving a dual-purpose function. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 6 、 7 The following are schematic diagrams of the lifting status of two types of horizontal motor bases. DETAILED DESCRIPTION

[0018] In order to facilitate understanding of the technical solution of the present invention, first combine Figure 3 、 5 6. Briefly describe the motor base for horizontal or vertical arrangements. Figure 5 、 6The motor base in the figure is the most common cast motor base 1. The motor base 1 shown in the figure can be a casting that has not yet been finely processed, a semi-finished part that has undergone some processing steps, or a state after the fine processing steps are completed. The outer wall of one end of the motor base 1 shown in the figure is arranged at intervals with end cover connecting seats 2 for connecting and installing end covers, also commonly known as ear covers. According to the motor specifications and design requirements, the end cover connecting seats 2 in the accompanying drawings are conventionally set with three at one end, and there are also arrangements of 4, 5 or 6. Since the inner end face of the end cover connecting seat 2, that is, the end face away from the end where it is located, is a non-assembly face, in other words, the assembly face of the end cover connecting seat 2 that fits with the end cover is the outer end face. The present invention selects the inner end face of the end cover connecting seat 2 as the force-bearing face during lifting, combined with Figure 3 When the motor base 1 is arranged vertically, the inner end surface of the upper end cover connecting base 2 faces downward.

[0019] in addition, Figure 5 When the motor base 1 is arranged horizontally, the plate surfaces of the heat dissipating fins 3 at both sides thereof are substantially horizontal. When the present invention is used for lifting, the lower plate surfaces of the heat dissipating fins 3 at both sides serve as the force-bearing surfaces during lifting.

[0020] A motor base hanger, the upper ends of the first, second and third hangers 11, 12 and 13 of the top base 10 are hingedly connected by a horizontally arranged first hinge shaft 11A, a second hinge shaft 12A and a third hinge shaft 13A at the edge of the disk, the lower ends of the first, second and third hangers 11, 12 and 13 have a first hook 111, a second hook 121 and a third hook 131 bent inwardly, and when the first hook 111, the second hook 121 and the third hook 131 are at the same height, the relative positions of the first hook 111, the second hook 121 and the third hook 131 coincide with the corresponding positions of the end cover connecting base 2 on the motor base 1.

[0021] When using the lifting device provided by the above-mentioned scheme to lift the motor base 1 arranged horizontally or vertically, it is only necessary to appropriately adjust the opening of the lower ends of the first lifting rod 11, the second lifting rod 12, and the third lifting rod 13 to easily hook the first hook 111, the second hook 121, and the third hook 131 to the end cover connecting base 2 on the motor base 1, and to lift the vertically arranged motor base 1. Similarly, by adjusting the opening of the lower ends of the first lifting rod 11, the second lifting rod 12, and the third lifting rod 13, the first hook 111, the second hook 121, and the third hook 131 can be easily placed on both sides of the horizontally arranged motor base 1 and can be reliably hooked on the heat dissipation fins on both sides for lifting.

[0022] Furthermore, a turntable 20 is rotatably provided on the top seat 10, and a first hinge shaft 11A and a second hinge shaft 12A are arranged at the edge of the top seat 10 to hingeably connect the upper ends of the first suspension rod 11 and the second suspension rod 12, and a third hinge shaft 13A is arranged at the edge of the turntable 20 to hingeably connect the upper end of the third suspension rod 13; when the turntable 20 rotates, the first hook 111, the second hook 121 and the third hook 131 are respectively located at corresponding positions of the end cover connecting seat 2 for hooking the upper end of the vertical motor base 1, and are used for hooking the vertical motor base 1 for lifting, or the rotation center of the turntable 20, the third suspension rod 13 and one of the first suspension rod 11 and the second suspension rod 12 are coplanar, and are used for hooking the horizontal motor base 1 for lifting.

[0023] Furthermore, when the turntable 20 rotates, the first suspension rod 11, the second suspension rod 12, and the third suspension rod 13 are respectively located in plumb planes spaced 120 degrees apart from each other.

[0024] In the above solution, when the turntable 20 rotates to the first position, the Figure 2a The positional relationship between the first suspender 11, the second suspender 12 and the third suspender 13 corresponds to the position of the three end cover connection bases 2 at the upper end of the vertically arranged motor base 1. Figure 1 , 2, 6, properly unfold the first suspension rod 11, the second suspension rod 12 and the third suspension rod 13 so that the area they surround can just accommodate the upper end of the motor base 1, and the first hook 111, the second hook 121 and the third hook 131 are just hooked on the inner end surface or the lower end surface of the end cover connecting seat 2 at the upper end, and now it can be safely lifted. In Figure 3, the end cover connecting seat 2 of the motor base 1 arranged vertically is symmetrically arranged in three directions, so the first hook 111, the second hook 121 and the third hook 131 are also equally divided and symmetrically arranged in the circumferential direction, that is, it can be understood that in the circumferential direction, the first suspension rod 11, the second suspension rod 12, the third suspension rod 13 and the plumb bob surfaces of the first hook 111, the second hook 121 and the third hook 131 thereon are offset 120 degrees from each other; when the turntable 20 rotates to the second position, combined with Figure 2b 、 5 6. The positional relationship between the first hook 111 and the second hook 121 remains unchanged, and the position of the third hook 131 is relatively close to one of the first hook 111 and the second hook 121. At this time, the first hook 111 and the second hook 121, which are naturally hanging, can be hooked on the same heat dissipation fin 3 on one side of the motor base 1, and the third hook 131 is hooked on a heat dissipation fin 3 on the opposite side. At this time, the horizontally arranged motor base 1 can be lifted. The solution of rotatably setting the turntable 20 on the top base 10 adopted in the present invention facilitates the indexing operation to adjust the positional relationship between the first hook 111, the second hook 121 and the third hook 131, so as to correspond to the lifting of the motor base 1 arranged horizontally or vertically.

[0025] The first, second, and third suspenders 11, 12, and 13 are generally curved rods, and are arranged obliquely with a small spacing between the upper ends and a large spacing between the lower ends. When the first, second, and third hooks 111, 121, and 131 are hooked to the end cover connector 2 or the heat dissipation fins 3 of the motor base 1, the lower sections of the first, second, and third suspenders 11, 12, and 13 are vertical. With the above solution, the dimensions of the top base 10 and the turntable 20 can be set smaller, while ensuring that when the first, second, and third hooks 111, 121, and 131 are hooked to the end cover connector 2 or the heat dissipation fins 3 of the motor base 1, the first, second, and third suspenders 11, 12, and 13 do not interfere with the motor base 1, thereby ensuring the safety and reliability of the lifting operation.

[0026] As a preferred embodiment, the top seat 10 is a disc-shaped plate with an upward vertical arrangement of a sling 14 in the middle. The sling 14 passes through the circular through-hole in the middle of the turntable 20, and the upper end is connected to a hook component 30 that cooperates with the lifting hook. The sling 14 is provided on the top seat 10 to ensure that the sling of the present invention can be conveniently matched with the lifting hook. The lifting hook here can be regarded as a hook or wire rope on the lifting equipment. The lifting hook can be conveniently hooked on the hook component 30 connected to the upper end of the sling 14. When the sling 14 is raised or lowered, the top seat 10 lifts the turntable 20 together. In addition, the through-hole in the turntable 20 not only contributes to the passage of the sling 14, but also relatively determines the rotation axis of the turntable 20, that is, the sling 14 constitutes the rotation center of the turntable 20.

[0027] The upper end of the hanging post 14 is provided with a threaded hole for connecting the screw of the hook component 30, thereby forming a detachable connection scheme between the two, which can facilitate the turntable 20 to be first placed on the hanging post 14 for assembly, and then the hanging post 14 and the hook component 30 are connected, and the size of the hook component 30 can be selected to be an appropriate size. When the hook component 30 is appropriate, it is convenient to connect with the lifting hook and ensure that the turntable 20 does not slip off the hanging post 14, because it is very common for the hanging post 14 to be in a horizontal state when the sling is idle and stored.

[0028] More preferably, the first hinge axis 11A and the second hinge axis 12A are coplanar, and the third hinge axis 13A is parallel to the plane where the first hinge axis 11A and the second hinge axis 12A are located. The first hinge axis 11A and the second hinge axis 12A are arranged on the top seat 10 in the shape of a disc plate for articulating the first hanger 11 and the second hanger 12. The angle between the plumb planes where the first hanger 11 and the second hanger 12 are located is 120 degrees. This is set in accordance with the relative position of the end cover connecting seat 2 on the motor base 1 of conventional technology. The coplanarity of the first hinge axis 11A and the second hinge axis 12A can set the length and shape of the first hanger 11 and the second hanger 12 to be the same, reducing processing costs and the inventory of spare parts. The turntable 20 is pressed on the top seat 10, so there is a height difference between the two. Therefore, the third hinge axis 13A can be set higher than and parallel to the plane where the first hinge axis 11A and the second hinge axis 12A are located.

[0029] The turntable 20 is an annular disk with a radially outwardly projecting projection 21 on its rim. The third hinge axis 13A is disposed on the projection 21. A pin hole 15 extending through the disk surface is disposed on the rim of the top seat 10. A limit pin 40 is inserted into the pin hole 15. The limit pin 40 is located along the movement path of the projection 21, and the projection 21 is circumferentially displaced to positions on either side of the pin hole 15 for inserting the limit pin 40. The projection 21 is provided to facilitate the placement of the third hinge axis 13A and to cooperate with the limit pin 40. While ensuring that the turntable 20 can rotate, it also provides a position limit. During rotation, the limit pin 40 needs to be withdrawn and then reinserted after rotation is complete. Alternatively, if the limit pin 40 is fixed to the top seat 10 and cannot be removed, the turntable 20 can be rotated by appropriately displacing the axial direction to allow the limit pin 40 to pass. The turntable 20 is then axially reset to fit the top seat 10.

[0030] At least two pin holes 15 are provided at intervals, and the protrusions 21 are located circumferentially to the sides of or between the two pin holes 15. The requirement that at least two pin holes 15 be provided here ensures that, after a limit pin 40 is inserted into the pin hole 15, the turntable 20 can be restricted to two positions. Furthermore, the plug-in coupling between the pin hole 15 and the limit pin 40 facilitates rotational adjustment compared to a solution where the limit pin 40 is fixed to the top seat 10. Because the turntable 20 is connected to the third suspension rod 13, axial displacement and circumferential rotation of the turntable 20 are relatively laborious.

[0031] The pin holes 15 are provided in two in order to cooperate with the scheme disclosed below in which a C-shaped opening ring 16 is provided at the edge of the upper plate surface of the top seat 10. Specifically, the pin holes 15 are arranged at the opening portion of the opening ring 16, and the circumferential spacing area between the first end 161 of the opening ring 16 and the limit pin 40 and the circumferential spacing area between the second end 162 and the limit pin 40 constitute the circumferential limiting area of ​​the protrusion 21.

[0032] First of all, it should be explained that Figure 2a 、 2b The setting of the C-shaped opening ring 16 can improve the strength of the top seat 10 and reserve a rotation area for the convex portion 21 set at the edge of the turntable 20. At the same time, the end of the C-shaped opening ring 16 constitutes the two extreme positions of the turntable 20. With the reserved 120° missing arc length section, the first suspension rod 11, the second suspension rod 12, and the third suspension rod 13 are placed at the circumferential three-division position, or the first suspension rod 11 and the second suspension rod 12 maintain an angle of 120° and the third suspension rod 13 are placed at the circumferential three-division position. The boom 13 is coplanar with one of the first boom 11 and the second boom 12, that is, the following more preferred solution is realized, that is, the first boom 11, the second boom 12 and the third articulated shaft 13A articulatedly connected to the third boom 13 are respectively located in three plumb planes distributed at a circumferential interval of 120°, or the first boom 11 and the second boom 12 are circumferentially spaced 120° and one of the first boom 11 and the second boom 12 and the third articulated shaft 13A are located in the same plumb plane.

[0033] Since the motor base 1 has a wide variety of specifications, in order to adapt to larger motor bases 1 without increasing the radial size of the top base 10 accordingly, the following solution can be adopted: a first cantilever rod 17 and a second cantilever rod 18 are radially arranged at the edge of the top base 10, with a circumferential spacing of 120° between them. The suspended ends of the first cantilever rod 17 and the second cantilever rod 18 are hingedly connected to the upper ends of the first and second hanger rods 11 and 12 by a first hinge axis 11A and a second hinge axis 12A. A third cantilever rod 19 is radially arranged at the edge of the turntable 20, and the suspended end of the third cantilever rod 19 is hingedly connected to the upper end of the third hanger rod 13 by a third hinge axis 13A. Since larger motor bases 1 are heavier, the addition of a C-shaped opening ring 16 not only improves the strength of the top base 10 but also facilitates the installation of the third cantilever rod 19. By setting the first cantilever rod 17, the second cantilever rod 18 and the third cantilever rod 19, it can be ensured that the rod bodies of the first cantilever rod 11, the second cantilever rod 12 and the third cantilever rod 13 are in a hanging posture as much as possible during lifting, and the first hook 111, the second hook 121 and the third hook 131 are flush with the corresponding parts on the motor base 1, ensuring a sense of safety during lifting.

[0034] The third cantilever rod 19 is located within three plumb planes spaced 120° apart from the first cantilever rod 17 and the second cantilever rod 18, or is located at a position where the third cantilever rod 19 shares a plumb plane with one of the first cantilever rod 17 and the second cantilever rod 18. This solution ensures that even when the first cantilever rod 17, the second cantilever rod 18, and the third cantilever rod 19 are provided, the first hook 111, the second hook 121, and the third hook 131 are flush with corresponding portions of the motor base 1.

[0035] It should be noted that when the size of the top seat 10 is significantly smaller than the radial size of the motor base 1, the solution of adding a third cantilever rod 19 to the first cantilever rod 17 and the second cantilever rod 18 can lift the larger motor base 1. When the radial size of the top seat 10 is basically the same as or slightly smaller than that of the motor base 1, there is no need to add the third cantilever rod 19 to the first cantilever rod 17 and the second cantilever rod 18. Instead, the first cantilever rod 11 and the second cantilever rod 12 are hinged at the edge of the top seat 10, and a bulge 21 is set at the edge of the turntable 20 to hinge the third cantilever rod 13. Therefore, it can be understood that when the third cantilever rod 19 is very short, it becomes the bulge 21, and the third cantilever rod 19 added as needed is naturally formed by the bulge 21 extending radially outward in a cantilever shape. There is no essential difference between the two. The focus of the difference lies in the different names defined according to their length.

[0036] In order to reliably and safely connect the first hook 111, the second hook 121, and the third hook 131 to the end cover connection base 2 or the heat dissipation fin 3 on the motor base 1, the first hook 111, the second hook 121, and the third hook 131 are all plate-shaped, and the inner side edge contour for hooking the motor base 1 is arc-shaped or bent. Figure 6 As shown, the inner side plate edge profiles of the first hook 111, the second hook 121 and the third hook 131 are bent, and the first hook left and right oblique edges 111b and 111c are provided on both sides of the first side 111a of the first hook, the second hook left and right oblique edges 121b and 121c are provided on both sides of the first side 121a of the second hook, and the third hook left and right oblique edges 131b and 131c are provided on both sides of the first side 131a of the third hook. The angle between the left oblique edge 111b of the first hook and the right oblique edge 121c of the second hook is less than 10°, and the angle between the right oblique edge 111c of the first hook, the left oblique edge 121b of the second hook and the left oblique edge 131b of the third hook is less than 10°.

[0037] Figure 6In the figure, the right oblique edge 111c of the first hook and the left oblique edge 121b of the second hook are simultaneously hooked to the root position of the same heat sink 3 on the same side of the motor base 1, and the left oblique edge 131b of the third hook is hooked at the root position of another opposite heat sink 3. Therefore, there is a large hanging and fitting area between the first hook 111, the second hook 121, and the third hook 131 and the heat sink 3. At this time, the right oblique edge 111c of the first hook, the left oblique edge 121b of the second hook and the left oblique edge 131b of the third hook are almost against the outer wall of the motor base 1.

[0038] Figure 7 In the embodiment, the left oblique side 111b of the first hook and the right oblique side 121c of the second hook are almost parallel to each other, that is, the angle between them is less than 10°, which ensures that the left oblique side 111b of the first hook and the right oblique side 121c of the second hook are in a mating state almost against the outer wall of the motor base 1, and the third hook 131 can be hung on the inner wall of the tube cavity at one end of the motor base 1, providing a sufficiently large hanging area, thereby avoiding the safety and reliability of lifting.
