Description
Technical Field
[0001] This utility model relates to a lifting tool, and more particularly to a long eccentric lifting tool with a rectangular cross-section for easy disassembly. Background Technology
[0002] Currently, when moving or transporting long eccentric components with rectangular cross-sections, such as automotive front axle housings, it is necessary to use lifting equipment to lift them and move them from one location to another. Because long eccentric components with rectangular cross-sections are relatively heavy, conventional lifting hooks cannot accurately adjust the posture of the long eccentric component after lifting. When lifted, the bottom surface of the long eccentric component is not parallel to the ground, and its edges are easily damaged when placed. At the same time, long eccentric components with rectangular cross-sections are relatively large, requiring heavy lifting hooks. After the long eccentric component is moved into place, removing the lifting equipment is difficult due to the rectangular cross-section of the component. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a long eccentric member with a rectangular cross-section for easy disassembly and lifting.
[0004] The technical solution adopted in this invention is as follows.
[0005] A long eccentric lifting device with a rectangular cross-section for easy disassembly is characterized by comprising a support block, two hook groups located on the left and right sides of the support block respectively, and a crossbar passing through the support block, wherein each hook group is connected to the crossbar; the left and right sides of the support block are parallel to each other and both perpendicular to the central axis of the crossbar.
[0006] Each hook assembly includes a first square hook and a second square hook; the hooking direction of the first square hook is set opposite to the hooking direction of the second square hook; each first square hook and each second square hook is hinged to the crossbar; the left and right sides of each first square hook are perpendicular to the central axis of the crossbar; the left and right sides of each first square hook are perpendicular to the central axis of the crossbar.
[0007] Each first square hook has a first horizontal circular hole at its top, and the crossbar passes through the nearest first horizontal circular hole;
[0008] Each second square hook has several second horizontal circular holes of different heights at its upper end. Each crossbar passes through a second horizontal circular hole of the second square hook closest to it, and the two crossbars pass through the second horizontal circular holes at the same height.
[0009] The beneficial effects of this invention are as follows: During operation, the support block is moved to the upper part of the middle of the long eccentric component, and each of the first square hooks is manually hooked onto the long eccentric component along its eccentric side, while each of the second square hooks is hooked onto the long eccentric component along its non-eccentric side. Since the two hook sets are distributed on both sides of the support block, the support block limits the movement of the two first square hooks and the two second square hooks, allowing the long eccentric component to be stably lifted; because the upper end of the second square hook is provided with several second horizontal circular holes of different heights, such as...Figure 9 As shown, by adjusting the hinge position of the second hook and the crossbar, when lifting the long eccentric component, the crossbar and the long eccentric component are positioned in a plane perpendicular to the ground. This ensures that the bottom surface of the long eccentric component is parallel to the ground when it is lifted, facilitating its transport and preventing damage to its edges. Since the crossbar passes through the nearest first horizontal circular hole, as... Figure 10 As shown, after the long eccentric component is transferred, the first square hook can be rotated counterclockwise to separate from the non-eccentric side of the long eccentric component, and then the second square hook can be removed longitudinally. The whole process is relatively labor-saving and fast. This utility model has the advantages of simple structure, convenient operation, and labor saving.
[0010] As a preferred technical solution, the two hook sets are symmetrical about the centroid of the support block; the support block is connected to the suspension rope.
[0011] As a preferred technical solution, the top of the support block is connected to a vertical plate, and the vertical plate is provided with a through hole for connecting the suspension rope, and the suspension rope is connected to the through hole for connecting the suspension rope.
[0012] As a preferred technical solution, the support block is provided with horizontal mounting holes for a crossbar. The crossbar passes through these holes, and both ends of the crossbar are threaded with limiting nuts. This technical solution allows adjustment of the proximity between the first and second hooks of each hook assembly. After the first and second hooks are engaged with the long eccentric component, the limiting nuts can be rotated to lock the first and second hooks, preventing them from disengaging.
[0013] As a preferred technical solution, the limiting nut is provided with a drive arm that facilitates rotation of the limiting nut.
[0014] As a preferred technical solution, the tip of the first hook contacts the side of the support block near the support block, and the tip of the second hook contacts the side of the first hook away from the support block near the support block. The limiting nut contacts the side of the second hook away from the support block.
[0015] or,
[0016] The tip of the second hook is close to the side of the support block and contacts the support block, the tip of the first hook is close to the side of the support block and contacts the tip of the second hook away from the side of the support block, and the limiting nut is close to the side of the support block and contacts the tip of the first hook away from the side of the support block.
[0017] As a preferred technical solution, the first square hook includes a first upper inclined plate, a first middle vertical plate, and a first lower inclined plate. The top of the first upper inclined plate is provided with a first horizontal circular hole. The angle between the centerline of the first upper inclined plate and the centerline of the first middle vertical plate is an obtuse angle, and the angle between the centerline of the first lower inclined plate and the centerline is a right angle. By adopting this technical solution, it can be ensured that the first square hook tightly grips the long eccentric component when it is engaged with it.
[0018] As a preferred technical solution, each of the first square hooks has a first transverse axis on the side away from the support block, and the first transverse axis is located at the connection between the first upper inclined plate and the first middle vertical plate.
[0019] As a preferred technical solution, the second square hook includes a second upper inclined plate, a second middle vertical plate, and a second lower inclined plate. The top of the second upper inclined plate has several second horizontal circular holes. The angle between the centerline of the second upper inclined plate and the centerline of the second middle vertical plate is an obtuse angle, and the angle between the centerline of the second lower inclined plate and the centerline of the second middle vertical plate is a right angle. This technical solution ensures that the second square hook firmly grips the long eccentric component when it is engaged with it.
[0020] As a preferred technical solution, the length of the first upper inclined plate is equal to the length of the second upper inclined plate; the length of the first middle vertical plate is equal to the length of the second middle vertical plate; and the length of the second lower inclined plate is greater than the length of the first lower inclined plate. This technical solution reduces the difficulty of separating the first square hook from the long eccentric component, while simultaneously increasing the contact between the second square hook and the bottom of the long eccentric component during engagement, thereby enhancing the stability of the hook.
[0021] As a preferred technical solution, the first lower inclined plate is provided with a first groove on the side near the first upper inclined plate, and the second lower inclined plate is provided with a second groove on the side near the second upper inclined plate.

[0048] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.
[0049] Example 1. As... Figure 1-10 As shown, a long eccentric member with a rectangular cross-section is used for easy disassembly and lifting. It includes a support block 1, two hook groups located on the left and right sides of the support block 1 respectively, and a crossbar 3 passing through the support block 1. Each hook group is connected to the crossbar 3. The left and right sides of the support block 1 are parallel to each other and perpendicular to the central axis of the crossbar 3.
[0050] Each hook assembly includes a first square hook 21 and a second square hook 22; the hooking openings of the first square hook 21 and the second square hook 22 face each other; each first square hook 21 and each second square hook 22 is hinged to the crossbar 3; the left and right sides of each first square hook 21 are perpendicular to the central axis of the crossbar 3. Specifically, referring to 3-4, the hooking opening of the first square hook 21 faces forward, and the hooking opening of the second square hook 22 faces backward.
[0051] refer to Figures 9-10 Each first square hook 21 has a first horizontal circular hole 210 at its top end, and the crossbar 3 passes through the first horizontal circular hole 210 closest to it.
[0052] Each second square hook 22 has five second horizontal circular holes 220 of different heights at its upper end. Each horizontal bar 3 passes through a second horizontal circular hole 220 of the second square hook 22 closest to it, and the second horizontal circular holes 220 through which the two horizontal bars 3 pass are at the same height.
[0053] The two hook sets are symmetrical about the centroid of the support block 1; the support block 1 is connected to the suspension rope 4.
[0054] The top of the support block 1 is connected to a vertical plate 11, and the vertical plate 11 is provided with a hanging rope connection through hole 12. The hanging rope 4 is connected to the hanging rope connection through hole 12.
[0055] The top of each second hook 22 is close to the side of the support block 1 and contacts the support block 1. The top of the first hook 21 is close to the side of the support block 1 and contacts the top of the second hook 22 away from the side of the support block 1. The limiting nut 5 is close to the side of the support block 1 and contacts the top of the first hook 21 away from the side of the support block 1.
[0056] The first square hook 21 includes a first upper inclined plate 211, a first middle vertical plate 212, and a first lower inclined plate 213. The top of the first upper inclined plate 211 has a first horizontal circular hole 210. The angle between the centerline of the first upper inclined plate 211 and the centerline of the first middle vertical plate 212 is an obtuse angle, and the angle between the centerline of the first lower inclined plate 213 and the centerline of the first middle vertical plate 212 is a right angle. This technical solution ensures that the first square hook 21 tightly grips the long eccentric component when it is engaged with it. The angle between the centerline of the first upper inclined plate 211 and the centerline of the first middle vertical plate 212 is 120 degrees.
[0057] The support block 1 has horizontal mounting holes 10 for the crossbar 3, which passes through the mounting holes 10. Both ends of the crossbar 3 are threaded with limiting nuts 5. This technical solution allows adjustment of the proximity between the first square hook 21 and the second square hook 22 in each hook assembly. After the first square hook 21 and the second square hook 22 are engaged with the long eccentric component, rotating the limiting nuts 5 tightens the first square hook 21 and the second square hook 22, ensuring close contact between the first square hook 21 and the support block 1, and between the second square hook 22 and the first square hook 21, preventing disengagement during hoisting. During unloading, rotating the limiting nuts 5 loosens the first square hook 21 and the second square hook 22, allowing them to rotate and facilitating unloading.
[0058] The second square hook 22 includes a second upper inclined plate 221, a second middle vertical plate 222, and a second lower inclined plate 223. The top of the second upper inclined plate 221 is provided with several second horizontal circular holes 220. The angle between the centerline of the second upper inclined plate 221 and the centerline of the second middle vertical plate 222 is 120 degrees, and the angle between the centerline of the second lower inclined plate 223 and the centerline of the second middle vertical plate 222 is a right angle. This technical solution ensures that the second square hook 22 firmly grips the long eccentric component when it is engaged with it.
[0059] The first lower inclined plate 213 has a first groove 214 on its side near the first upper inclined plate 211, and the second lower inclined plate 223 has a second groove 224 on its side near the second upper inclined plate 221.
[0060] The beneficial effects of this invention are: during operation, such as Figure 11-13 As shown, move the support block 1 to the middle of the long eccentric component. Manually hook each of the first square hooks 21 along the eccentric side of the long eccentric component 7 (which has a rectangular cross-section) to the long eccentric component, and hook each of the second square hooks 22 along the non-eccentric side of the long eccentric component. Since the two hook groups are distributed on both sides of the support block 1, the support block 1 provides a limiting function for the two first square hooks 21 and the two second square hooks 22, which can stably lift the long eccentric component. Because the upper end of the second square hook 22 has several second horizontal circular holes 220 of different heights, such as... Figure 9As shown, by adjusting the hinge position between the second hook 22 and the crossbar 3, when lifting the long eccentric component 7, the crossbar 3 and the centroid of the long eccentric component are located in the same plane, and the plane is perpendicular to the ground. This ensures that the bottom surface of the long eccentric component is parallel to the ground when it is lifted, facilitating its transport and preventing damage to its edges. Since the crossbar 3 passes through the nearest first horizontal circular hole 210, as... Figure 10 As shown, after the long eccentric part is transferred, the first square hook 21 can be rotated counterclockwise to separate from the non-eccentric side of the long eccentric part, and then the second square hook 22 can be removed longitudinally. The whole process is relatively labor-saving and fast.
[0061] Example 2. (As shown) Figure 14-15 As shown, the difference between this embodiment and Embodiment 1 is that: each first square hook 21 has a first transverse axis 6 on its side away from the support block 1, and the first transverse axis 6 is located at the connection between the first upper inclined plate 211 and the first middle vertical plate 212. The first transverse axis 6 facilitates the rotation of the first square hook 21 during unloading. The angle between the centerline of the first upper inclined plate 211 and the centerline of the first middle vertical plate 212 is 110 degrees. The angle between the centerline of the second upper inclined plate 221 and the centerline of the second middle vertical plate 222 is also 110 degrees.
[0062] Example 3. (As shown) Figure 16 As shown, the difference between this embodiment and Embodiment 1 is that the length of the first upper inclined plate 211 is equal to the length of the second upper inclined plate 221; the length of the first middle vertical plate 212 is equal to the length of the second middle vertical plate 222; and the length of the second lower inclined plate 223 is greater than the length of the first lower inclined plate 213. This technical solution reduces the difficulty of separating the first square hook 21 from the long eccentric component, while simultaneously increasing the contact between the second square hook 22 and the bottom of the long eccentric component during engagement, thereby increasing the stability of the hook.
[0063] Example 4. (As shown) Figure 17 As shown, the difference between this embodiment and Embodiment 1 is that: the top of the first square hook 21 is in contact with the side of the support block 1 near the support block 1, and the top of the second square hook 22 is in contact with the side of the first square hook 21 away from the support block 1 near the support block 1. The limiting nut 5 is in contact with the side of the second square hook 22 away from the support block 1. A first transverse shaft 6 is provided on the side of each first square hook 21 away from the support block 1, and the first transverse shaft 6 is located at the connection between the first upper inclined plate 211 and the first middle vertical plate 212. The first transverse shaft 6 facilitates the rotation of the first square hook 21 during unloading. The angle between the centerline of the first upper inclined plate 211 and the centerline of the first middle vertical plate 212 is 130°. The angle between the centerline of the second upper inclined plate 221 and the centerline of the second middle vertical plate 222 is 130°.
[0064] Example 5. (As shown) Figure 18As shown, this embodiment differs from Embodiment 1 in that each limiting nut 5 is provided with a drive arm 51 for convenient rotation of the limiting nut 5. The angle between the center line of the first upper inclined plate 211 and the center line of the first middle vertical plate 212 is 115 degrees. The angle between the center line of the second upper inclined plate 221 and the center line of the second middle vertical plate 222 is 115 degrees. Each first square hook 21 has a first transverse shaft 6 on its side away from the support block 1, and the first transverse shaft 6 is located at the connection between the first upper inclined plate 211 and the first middle vertical plate 212.
