Description

Technical Field

[0001] The invention relates to the field of wheel hub hoisting onto a machine, and in particular to a wheel hub hoisting tool, a wheel hub hoisting device and a wheel hub hoisting method. Background Art

[0002] The wheel boring machine for vehicles is mainly used for processing the wheel hub of vehicles. Because the wheel hub is a cast iron part, it is relatively heavy and one person cannot lift it. Three people are needed to operate it, which is unsafe and has low labor efficiency. When lifting, it is easy to slip and fall off the hands, causing injuries, which is a safety hazard.

[0003] The following methods are currently available:

[0004] The single-strand wire rope locking lifting method cannot balance the hoisted wheel hub. When it is lifted onto the equipment, the wheel hub cannot be balanced, so the operator needs to lift it level before putting it on, which is inconvenient and laborious.

[0005] The articulated bucket lifting method is to make two buckets hinged, and the two buckets together lift the wheel hub from the bottom. Since both sides are folded at the same time, the wheel hub can be lifted steadily. However, the production is complicated and difficult, and during operation, manual movement is required to get the wheel hub into the tooling to ensure a stable lift.

[0006] The clamp-type lifting method uses a clamp to clamp the wheel hub, and the clamping degree depends on the weight of the wheel hub. Due to the difference in weight of the wheel hub, there is a possibility of slippage during operation, and the production is also more complicated. Summary of the invention

[0046] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0047] Combine the following Figures 1 to 3 The wheel hub lifting tool 10 provided in this embodiment is described in detail.

[0048] Please refer to Figure 1 , Figure 2 as well as Figure 3The embodiment of the present invention provides a wheel hub hoisting tool 10 for connecting a wheel hub to a hoisting machine. The wheel hub hoisting tool 10 comprises a first locking rope 100, a second locking rope 200, a first spring 300, a second spring 310, a first hoisting rope 400, a second hoisting rope 410, a first locking assembly 500 and a second locking assembly 600; the first locking rope 100 has a first end and a second end, and the second locking rope 200 has a third end and a fourth end; the first end and the third end are connected by the first spring 300 and the first locking assembly 500 at the same time, and the first end and the third end are movably sleeved on the first hoisting rope 400; the second end and the fourth end are connected by the second spring 310 and the second locking assembly 600 at the same time, and the second end and the fourth end are movably sleeved on the second hoisting rope 410 at the same time; the first locking rope 1 00, the first spring 300, the second locking rope 200 and the second spring 310 are used to jointly form a tightening ring that wraps around the outer edge of the wheel hub; the two ends of the first lifting rope 400 and the two ends of the second lifting rope 410 are used to be hung on the lifting machine; the first locking assembly 500 has two states: unlocked and locked. When the first locking assembly 500 is in the unlocked state, the first end and the third end are tightened to each other under the action of the first spring 300, or the first locking assembly 500 is in the locked state, and the distance between the first end and the third end is fixed; the second locking assembly 600 has two states: unlocked and locked. When the second locking assembly 600 is in the unlocked state, the second end and the fourth end are tightened to each other under the action of the second spring 310, or the second locking assembly 600 is in the locked state, and the distance between the second end and the fourth end is fixed.

[0049] “The first end and the third end are connected through the first spring 300 and the first locking assembly 500 at the same time” means that the first end and the third end are connected through the first spring 300, and the first end and the third end are connected through the first locking assembly 500. The first spring 300 makes the first end and the third end have a movement tendency to be pulled closer to each other. After the first locking assembly 500 is unfastened, the first end and the third end can be pulled closer to each other under the action of the first spring 300. After the first locking assembly 500 is locked, the stroke between the first end and the third end is fixed, and they can no longer move closer or farther away from each other. Similarly, “the second end and the fourth end are connected through the second spring 310 and the second locking assembly 600 at the same time” means that the second end and the fourth end are connected through the second spring 310, and the second end and the fourth end are connected through the second locking assembly 600. The second spring 310 makes the second end and the fourth end have a movement tendency to be pulled closer to each other. After the second locking assembly 600 is unfastened, the second end and the fourth end can be pulled closer to each other under the action of the second spring 310. After the second locking assembly 600 is locked, the distance between the second end and the fourth end is fixed and they can no longer get closer or farther away from each other.

[0050] The first locking rope 100, the first spring 300, the second locking rope 200 and the second spring 310 are connected end to end to form a tightening ring. Due to the action of the first spring 300 and the second spring 310, the first locking rope 100 and the second locking rope 200 can automatically shrink, and the size of the tightening ring is adjustable, and can be put on the wheel hubs of different sizes. And under the action of the first spring 300 and the second spring 310, the first locking rope 100 and the second locking rope 200 can be tightened on the outer edge of the wheel hub synchronously, maintain a horizontal position with the wheel hub, avoid tilting relative to the wheel hub, and then ensure a smooth rise after lifting. In the actual operation process, the tightening ring is stretched and put on the outer edge of the wheel hub with the rim facing up, and then the first locking rope 100 and the second locking rope 200 clamp the wheel hub under the action of the first spring 300 and the second spring 310.

[0051] The first locking assembly 500 and the second locking assembly 600 have two states: unlocked and locked. When the first locking assembly 500 and the second locking assembly 600 are both in the unlocked state, the first locking rope 100 and the second locking rope 200 can freely expand and contract under the action of the first spring 300 and the second spring 310, close to the wheel hub, avoid gaps with the wheel hub, and ensure a stable position. When the first locking assembly 500 and the second locking assembly 600 are both in the locked state, the first locking rope 100 and the second locking rope 200 can no longer freely contract, and can tighten the wheel hub to prevent the wheel hub from slipping after lifting, while solving the problem of excessive spring stretching.

[0052] "The first end and the third end are movably mounted on the first lifting rope 400", then after the first lifting rope 400 is lifted, the first end and the third end can slide to a mutually balanced position relative to the first lifting rope 400, that is, the two ends of the first lifting rope 400, the first end and the third end are distributed in an equilateral triangle to ensure smooth lifting.

[0053] Similarly, "the second end and the fourth end are jointly movably mounted on the second lifting rope 410", then after the second lifting rope 410 is lifted, the second end and the fourth end can slide to a mutually balanced position relative to the second lifting rope 410, that is, the two ends of the second lifting rope 410, the second end and the fourth end are distributed in an equilateral triangle to ensure smooth lifting.

[0054] It should be noted that, in this embodiment, in order to ensure stability, the first locking rope 100 has the same size as the second locking rope 200. The first spring 300 has the same size as the second spring 310. The first hoisting rope 400 has the same size as the second hoisting rope 410. The first spring 300 and the second spring 310 are 3 cm long and 10 mm in diameter.

[0055] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, the first end of the first locking rope 100 forms a first rope ring 110, and the second end of the first locking rope 100 forms a second rope ring 120; the third end of the second locking rope 200 forms a third rope ring 210, and the fourth end of the second locking rope 200 forms a fourth rope ring 220; the first rope ring 110 and the third rope ring 210 are movably mounted on the first lifting rope 400, and the second rope ring 120 and the fourth rope ring 220 are movably mounted on the second lifting rope 410. The first locking rope 100 and the second locking rope 200 are steel wire ropes with a diameter of 6 mm and a length of 1050 mm. The rope ring is 50 mm based on the top of the rope ring.

[0056] The rope ring structure is adopted, and the cooperation with the first hoisting rope 400 and the second hoisting rope 410 is simple and quick. It also helps the first hoisting rope 400 and the second hoisting rope 410 to balance the hoisting hoop and the hub.

[0057] Specifically, the wheel hub lifting tool 10 further includes a plurality of rope buckles, and the first rope ring 110, the second rope ring 120, the third rope ring 210 and the fourth rope ring 220 are all equipped with rope buckles to improve the strength.

[0058] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, the first locking assembly 500 includes a first slide bar 510, a second slide bar 520, a first slide sleeve 530 and a first locking member 540; one end of the first slide bar 510 is fixed to the first end, and the other end of the first slide bar 510 is fixed to the first slide sleeve 530; one end of the second slide bar 520 is fixed to the third end, and the other end of the second slide bar 520 and the first slide sleeve 530 are movably arranged in the first slide sleeve 530; the first locking member 540 is movably connected to the first slide sleeve 530, and the first locking member 540 is used to abut and fix with the first slide bar 510 to lock the first locking assembly 500, or the first locking member 540 is used to disengage from the first slide bar 510 to unlock the first locking assembly 500. It should be noted that the structure of the second locking assembly 600 is the same as that of the first locking assembly 500, which will not be repeated here.

[0059] The second slide bar 520 is slidably matched with the first slide sleeve 530. During the sliding process of the second slide bar 520 relative to the first slide sleeve 530, the third end connected to the second slide bar 520 moves closer to or farther from the first end connected to the first slide bar 510. The manual distance adjustment between the first end and the third end is achieved by sliding the second slide bar 520 relative to the first slide sleeve 530. At this time, the first spring 300 is in a compressed or stretched state, which is specifically determined by the size of the clamping ring and the size of the wheel hub. In actual operation, when the first end and the third end are tightly attached to the wheel hub under the action of the first spring 300, the second slide bar 520 and the first slide sleeve 530 are connected and fixed by the first locking member 540, thereby fixing the distance between the first end and the third end.

[0060] Specifically, the diameter of the first slide bar 510 and the second slide bar 520 is 9 mm. The first slide sleeve 530 is provided with a first slide hole, and the second slide bar 520 slides through the first slide hole. The first fastener is a first bolt, and the first slide sleeve 530 is provided with a first screw hole, which is connected to the first slide hole. During the rotation of the first bolt relative to the first screw hole, it approaches or moves away from the middle of the first slide hole, and during the approaching process, it can resist the second slide bar 520 located in the first slide hole to achieve fixation.

[0061] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, the first locking assembly 500 further includes a second sliding sleeve 550; the end of the second sliding rod 520 away from the third end is fixed to the second sliding sleeve 550, and the first sliding rod 510 is movably arranged in the second sliding sleeve 550. Similarly, the structure of the second locking assembly 600 is the same as that of the first locking assembly 500, and will not be repeated.

[0062] The first slide bar 510 and the second slide bar 520 are arranged side by side. When the first slide bar 510 slides relative to the second slide sleeve 550, the second slide bar 520 slides synchronously relative to the first slide sleeve 530. After the second slide bar 520 and the first slide sleeve 530 are fixed, the position of the first slide bar 510 relative to the second slide sleeve 550 is fixed.

[0063] Specifically, the second sliding sleeve 550 is provided with a second sliding hole, and the first sliding rod 510 is slidably inserted into the second sliding hole.

[0064] Reference Figure 1 , Figure 2 as well as Figure 3In this embodiment, the first locking assembly 500 further includes a first support 560 and a second support 570; the first slide bar 510 and the first rope ring 110 are fixed by the first support 560, and the second slide bar 520 and the third rope ring 210 are fixed by the second support 570; the two ends of the first spring 300 are respectively connected to the first support 560 and the second support 570. Similarly, the structure of the second locking assembly 600 is the same as that of the first locking assembly 500, and will not be repeated.

[0065] The first slide bar 510, the first end and the first spring 300 are connected together through the first support 560. The second slide bar 520, the third end and the other end of the first spring 300 are connected together through the second support 570, which simplifies the structure and improves the connection firmness.

[0066] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, the first support 560 includes a first nut 561, a second nut 562 and a third nut 563 arranged at an angle; the first slide bar 510 is threadedly fixed to the first nut 561, the first rope ring 110 is buckled on the second nut 562, and one end of the first spring 300 is buckled on the third nut 563. The structure of the second support 570 is the same as that of the first support 560, and will not be repeated.

[0067] The nut structure can simplify the assembly process. The first slide bar 510, the first rope ring 110 and one end of the first spring 300 can be assembled by buckling them together.

[0068] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, the first hoisting rope 400 has a fifth rope ring and a sixth rope ring at both ends; the second hoisting rope 410 has a seventh rope ring and an eighth rope ring at both ends; the fifth rope ring, the sixth rope ring, the seventh rope ring and the eighth rope ring are used to be buckled on the hoisting machine. The first hoisting rope 400 and the second hoisting rope 410 are steel wire ropes with a diameter of 6 mm and a length of 650 mm. The rope ring is 50 mm based on the top of the rope ring.

[0069] After the first lifting rope 400 passes through the first rope ring 110 and the third rope ring 210, and the second lifting rope 410 passes through the second rope ring 120 and the fourth rope ring 220, the fifth rope ring, the sixth rope ring, the seventh rope ring and the eighth rope ring are used to be buckled together on the lifting machine, with a simple structure and a quick assembly process.

[0070] Reference Figure 1 , Figure 2 as well as Figure 3The assembly process of a wheel hub lifting tool 10 provided in this embodiment includes: passing the first lifting rope 400 and the second lifting rope 410 through the two rope rings at both ends of the first locking rope 100 and the second locking rope 200 respectively; buckling the four rope rings of the first lifting rope 400 and the second lifting rope 410 into the safety buckle 700 to complete the assembly of the device; connecting the safety buckle 700 to the lifting device and it can be used.

[0071] Reference Figure 1 , Figure 2 as well as Figure 3 The working principle of a wheel hub lifting tool 10 provided in this embodiment includes: when in use, loosening the first locking component 500 and the second locking component 600 can satisfy the stretching of the first spring 300 and the second spring 310, and putting the tightening ring into the elliptical part of the wheel hub. At this time, the first spring 300 and the second spring 310 are contracted, and the first sliding bar 510 and the second sliding bar 520 slide into place in the contraction direction of the first spring 300, and the second locking component 600 also slides into place, tightens the first bolt, and locks the second locking component 600, that is, fixes the stroke of the first locking rope 100 and the second locking rope 200, and the heavy lifting device lifts the wheel hub.

[0072] The wheel hub lifting tool 10 provided in this embodiment has at least the following advantages:

[0073] During the hoisting process, the first locking rope 100 and the second locking rope 200 are automatically retracted due to the force of the first spring 300 and the second spring 310. The first locking rope 100 and the second locking rope 200 can be tightened on the wheel hub in time. The first locking rope 100 and the second locking rope 200 can be effectively fixed. The tightening time of the tightening ropes on both sides is balanced, which is not easy to cause skewness, and the hoisted object is balanced.

[0074] During the lifting process, the first locking assembly 500 and the second locking assembly 600 are used to help the first locking rope 100 and the second locking rope 200 to lock in place to prevent the suspended objects from slipping, thereby ensuring safety in use, preventing the risk of objects falling off, and eliminating sources of danger during the lifting process.

[0075] The wheel hubs of vehicles have different sizes depending on the vehicle model. When hoisting different wheel hubs, due to the contraction travel of the first spring 300 and the second spring 310, there is no need to re-network, which solves the purpose of using the same set of tools for different wheel hubs and reduces costs. During use, employees do not need to disassemble frequently, and labor efficiency is greatly improved.

[0076] It realizes the process transformation from manual to mechanical operation, with low cost and simple and easy operation. It is easy to operate, reduces labor consumption, improves labor efficiency, and reduces the number of operators from three to one.

After the wheel hub hoisting tool 10 is tightened with the wheel hub, the wheel hub is hoisted onto the machine by the hoisting machine. It can improve the problem of low efficiency and easy slipping of the manual operation of the wheel hub hoisting.

[0078] Specifically, the wheel hub lifting device also includes a motor, which is connected to the winch disc. The motor is used to drive the winch disc to rotate, thereby driving the wheel hub lifting tooling 10 to rise and fall.

[0079] In this embodiment, the wheel hub lifting tool 10 further includes a safety buckle 700 connected to the winch disc, and both ends of the first lifting rope 400 and both ends of the second lifting rope 410 are buckled on the safety buckle 700. Specifically, the fifth rope ring, the sixth rope ring, the seventh rope ring and the eighth rope ring are buckled on the safety buckle 700, and the connection process is simple.

[0080] The embodiment of the present invention further provides a wheel hub hoisting method, which is performed by using a wheel hub hoisting tool 10. The wheel hub hoisting method comprises the following steps:

[0081] Put the tightening ring onto the outer edge of the wheel hub with the flange facing upward; use the first locking assembly 500 in a locked state and the second locking assembly 600 in a locked state to fix the tightening ring on the outer edge of the wheel hub; at the same time, lift both ends of the first lifting rope 400 and both ends of the second lifting rope 410 to lift the wheel hub.

[0082] Push the wheel hub to be hoisted into the working range of the hanger machine, lay the wheel hub flat with the wheel hub flange facing upwards; operate the hoisting machine to lower the wheel hub hoisting tool 10 with the hoisting tool, unfasten the first locking assembly 500 and the second locking assembly 600, and insert the wheel hub hoisting tool 10 into the wheel hub to be processed. At this time, the clamping ring is located below the wheel hub flange, and the assembly process is completed; at this time, the first spring 300 and the second spring 310 shrink, the first locking rope 100 and the second locking rope 200 are tightened, and then the first locking assembly 500 and the second locking assembly 600 are locked. Start the motor, hoist the wheel hub onto the boring wheel hub frame, and lower the wheel hub to complete the wheel hub mounting process; loosen the hoisting rope, take the clamping ring off the wheel hub, and move it away to avoid affecting the wheel hub processing; the wheel hub dismounting process can be completed by performing the above steps in reverse.

[0083] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
