Description

Technical Field

[0001] The utility model belongs to the technical field of support roll lifting tools, and particularly relates to an automatic alignment tongue of a support roll lifting tool. Background Art

[0002] When the support roll lifting tool is hoisting, the contact position between the lifting tongue of the lifting tool and the lifting hole of the bearing seat is a contact plane, so that when the lifting tongue (as Figure 1 shown) enters the lifting hole of the bearing seat on the support roll, the contact areas of the four tongues with the lifting points are inconsistent. Personnel need to use a crowbar to make multiple adjustments. Only when the contact surfaces of the lifting points are basically the same can hoisting be carried out. The hoisting efficiency is slow, and major safety accidents are likely to occur during hoisting when the tongues are not aligned due to personnel negligence. Summary of the Utility Model

[0003] The technical problem to be solved by the present invention is that in the above-mentioned prior art, the contact position between the lifting tongue of the lifting tool and the lifting hole of the bearing seat is a contact plane, and the contact areas of the four tongues with the lifting points are inconsistent, resulting in complex operations caused by multiple manual adjustments.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] An automatic alignment tongue of a support roll lifting tool includes a tongue. An adjustment inclined surface part is provided on the contact plane where the upper end of the tongue contacts the lifting hole of the bearing seat. An adaptive slider with a spring is arranged in the slot of the adjustment inclined surface part. When the tongue rises after being inserted into the lifting hole of the bearing seat, the adjustment inclined surface of the tongue adjusts the contact position between the tongue and the lifting hole through sliding, and then through the automatic alignment of the adaptive slider, the insertion amounts of the two sides of the tongue into the lifting hole are made consistent.

[0006] Preferably, the adjustment inclined surface part is an inverted V shape. The side of the adjustment inclined surface part close to the contact plane is inclined to the right and upward, and the side of the adjustment inclined surface part facing away from the contact plane is inclined to the right and downward.

[0007] Preferably, an installation hole for being cooperatively installed on the support roll lifting tool is provided on the tongue.

[0008] Compared with the prior art, the technical effects and advantages of the utility model are:

[0009] The upper end of the automatic alignment tongue of the support roll lifting tool is designed with a contact plane for contacting the lifting hole of the bearing seat. There is an adjusting inclined surface on the contact plane, and this inclined surface can adjust the contact position between the tongue and the lifting hole. An adaptive slider with a spring is arranged in the slot of the adjusting inclined surface. When the tongue rises and engages with the lifting hole of the bearing seat, the slider slides along the adjusting inclined surface. The surface of the adaptive slider has protrusions. When the contact amounts on both sides of the tongue are inconsistent, the slider will continue to slide until the contact amounts on both sides are the same. Once the contact amounts on both sides of the tongue are the same, the adaptive slider will lock in place to ensure that unnecessary movement does not occur during the lifting process.

[0010] If the traditional tongue is not correctly aligned, lifting may cause safety accidents. The added adjusting inclined surface and adaptive slider can automatically adjust the position of the tongue, avoiding incorrect alignment caused by human negligence and safety risks during lifting. It takes 6 minutes to lift the support roll using the traditional tongue with a contact plane, while using the tongue with the newly added adjusting inclined surface and adaptive slider, the time is shortened to 1 minute, greatly reducing the personnel adjustment time, with each time reduction being approximately 5 minutes.

[0011] The automatic alignment function ensures that the tongues of the support roll lifting tool are inserted into the bearing seat lifting holes in the same position, providing an adequate contact support surface and improving the stability and reliability of the lifting process.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] The following is a further detailed description of the present application in conjunction with the attached Figure 2-3 drawings.

[0018] An embodiment of the present application discloses an automatic alignment tongue for a backup roll lifting tool, which includes a tongue 1. An adjustment inclined surface portion 5 is provided on a contact plane 4 where the upper end of the tongue 1 contacts a lifting hole 3 of a bearing block 2. An adaptive slider 7 with a spring is arranged in a slot 6 of the adjustment inclined surface portion 5. When the tongue 1 rises after being inserted into the lifting hole 3 of the bearing block 2, the adjustment inclined surface of the tongue 1 adjusts the contact position between the tongue 1 and the lifting hole 3 through sliding, and then through the automatic alignment of the adaptive slider 7, the insertion amounts of the two sides of the tongue 1 into the lifting hole 3 are made consistent, and there is sufficient contact support surface.

[0019] By adding the adjustment inclined surface portion 5 to the original contact plane 4 of the tongue 1, the contact position between the tongue 1 and the lifting hole 3 of the bearing block 2 can be automatically adjusted. At the same time, an adaptive slider 7 with a spring is added at the position of the adjustment inclined surface, so that the fixture can automatically align the position. The adaptive slider 7 slides along the adjustment inclined surface portion 5 until the contact amounts of the two sides of the tongue 1 reach consistency. In this process, the adaptive slider 7 will pass through a surface with protrusions to achieve precise adjustment. Once the contact amounts of the two sides of the tongue 1 reach consistency, the adaptive slider 7 will be locked in place to ensure that unnecessary movement does not occur during the lifting process.

[0020] The adjustment inclined surface portion 5 is in an inverted V shape. The side of the adjustment inclined surface portion 5 close to the contact plane 4 is inclined to the right and upward, and the side of the adjustment inclined surface portion 5 facing away from the contact plane 4 is inclined to the right and downward.

[0021] An installation hole 8 for mating and installing on a backup roll lifting tool 9 is provided on the tongue 1.

[0022] Adding the adjustment inclined surface portion 5 and the adaptive slider 7 can avoid major safety accidents that may occur during lifting when the tongue 1 is not aligned due to human negligence; the tongue 1 automatically adjusts and aligns, improving the lifting efficiency of the backup roll. It takes 6 minutes to lift the backup roll with the original tongue 1 with a contact plane 4, and now it only takes 1 minute to lift the backup roll with the tongue 1 with the added adjustment inclined surface portion 5 and the adaptive slider 7 in cooperation with the backup roll lifting tool 9, reducing the personnel adjustment time by about 5 minutes per time; the automatic alignment ensures that the tongues 1 of the backup roll lifting tool 9 are inserted into the lifting holes 3 of the bearing block 2 in the same position, with sufficient contact amount, improving the safety of lifting.

[0023] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
