[0007] Optionally, the chute is also provided with a third section, which is connected to the extension path of the first section and is set at an angle. The rope is looped on the hanging column, and the hanging column is driven to slide relative to the through hole and drive the protrusion to move from the first section to the end of the third section away from the first section, so that the hanging column switches from the protruding position to the semi-protruding position. Optionally, a cover plate is fixedly provided at the end of the lifting column near the through hole. The cover plate is provided with an extension lug protruding relative to the peripheral wall of the lifting column. The extension lug is used to limit the rope.

[0017] One aspect of the embodiments of this application, such as Figure 1 and Figure 2 As shown, a lifting tool 100 is provided, including a support frame 110 and a lifting column 120. A through hole 111 is provided on the side of the support frame 110, and the lifting column 120 is slidably inserted into the through hole 111. A groove 112 communicating with the through hole 111 is provided on the support frame 110. The groove 112 includes a first section 1121 and a second section 1122 whose ends are connected and arranged at an included angle. The extending direction of the first section 1121 is the same as the axial direction of the through hole 111. The lifting column 120... The column 120 has a protrusion 121 that slides with the groove 112; when in the protruding position, one end of the column 120 protrudes relative to the side of the support frame 110, and the protrusion 121 is located at the end of the first section 1121 away from the second section 1122; the column 120 is driven to slide relative to the through hole 111 and drive the protrusion 121 to move from the first section 1121 to the end of the second section 1122 away from the first section 1121, so that the column 120 switches from the protruding position to the storage position.

[0018] Specifically, the lifting tool 100 includes a support frame 110 and a lifting column 120. The support frame 110 has a bearing surface, and the lifting operation is performed by placing the heavy object to be lifted on the bearing surface. A through hole 111 is provided on the side of the support frame 110, and the lifting column 120 is slidably inserted into the support frame 110 through the through hole 111. A sliding groove 112 is provided on the support frame 110, and the sliding groove 112 communicates with the through hole 111. The sliding groove 112 includes a first section 1121 and a second section 1122, the ends of the first section 1121 and the second section 1122 are connected and set at an included angle, wherein the extending direction of the first section 1121 is the same as the axial direction of the through hole 111. A protrusion 121 is fixedly provided on the lifting column 120. When the lifting column 120 is slidably inserted into the support frame 110 through the through hole 111, the protrusion 121 is slidably engaged with the sliding groove 112.

[0019] During hoisting operations, such as Figure 1As shown, the lifting column 120 is in a protruding position, with one end of the lifting column 120 near the through hole 111 protruding relative to the side of the support frame 110. At this time, the protrusion 121 is located at one end of the first section 1121 of the slide groove 112 away from the second section 1122 of the slide groove 112. The lifting operation is performed by looping a rope around the protruding lifting column 120. After the lifting operation is completed, as follows... Figure 2 As shown, the drive column 120 slides into the support frame 110 relative to the through hole 111. The protrusion 121 on the drive column 120 slides from the end of the first segment 1121 near the through hole 111 to the end away from the through hole 111. Then, the drive column 120 is rotated, causing the protrusion 121 to slide from the end of the second segment 1122 near the first segment 1121 to the end away from the first segment 1121, thus switching the drive column 120 from the protruding position to the retracted position. The first segment 1121 allows the drive column 120 to slide out of or into the support frame 110 through the through hole 111. The second segment 1122 prevents the drive column 120 from sliding out of the support frame 110 during transportation. By driving the hanging column 120 to slide relative to the through hole 111 and causing the protrusion 121 to move from the first section 1121 to the second section 1122 away from the first section 1121, the hanging column 120 is switched from the protruding position to the storage position, which facilitates the storage and transportation of the support frame 110.

[0020] In some embodiments, the first segment 1121 and the second segment 1122 can be set at an acute angle or a right angle, and there is no specific limitation. For example Figure 1 As shown, the first segment 1121 and the second segment 1122 are set perpendicular to each other.

[0021] Optionally, such as Figure 3 As shown, the bottom of the first section 1121 and the second section 1122 is provided with a positioning structure 130. The protrusion 121 is limited by the positioning structure 130 so that the hanging column 120 is kept in the protruding position or the storage position. Specifically, the end of the first segment 1121 closest to the through hole 111 is the bottom of the groove of the first segment 1121. The end of the second segment 1122 furthest from the first segment 1121 is the bottom of the groove of the second segment 1122. Positioning structures 130 are respectively provided at the bottom of the groove of the first segment 1121 and the bottom of the groove of the second segment 1122. The protrusion 121 is limited by the positioning structure 130 at the bottom of the groove of the first segment 1121, so that the hanging column 120 is kept in the protruding position. The protrusion 121 is limited by the positioning structure 130 at the bottom of the groove of the second segment 1122, so that the hanging column 120 is kept in the stored position, preventing the hanging column 120 from sliding out of the carrier frame 110 due to shaking during transportation.

[0022] In some embodiments, the positioning structure 130 may be a snap-fit ​​or other structure with the same function, which is not limited here.

[0023] Optionally, the outer surface of the hanging column 120 near the through hole 111 is provided with an anti-slip structure, and the rope is sleeved on the anti-slip structure.

[0024] Specifically, an anti-slip structure is provided on the lifting column 120, located on the outer surface of the lifting column 120 near the through hole 111. During lifting operations, the rope is looped onto the anti-slip structure on the lifting column 120 to prevent the rope from slipping off the lifting column 120 during the lifting process.

[0025] In some implementations, the anti-slip structure can be raised dots or arc grooves, and there is no specific limitation.

[0026] Optionally, such as Figure 4 As shown, the slide 112 is also provided with a third section 1123. The third section 1123 is connected to the extension path of the first section 1121 and is set at an angle. The rope is sleeved on the hanging column 120. The hanging column 120 is driven to slide relative to the through hole 111 and drive the protrusion 121 to move from the first section 1121 to the end of the third section 1123 away from the first section 1121, so that the hanging column 120 switches from the protruding position to the semi-protruding position.

[0027] Specifically, the slide 112 also has a third section 1123, which is connected to the first section 1121. More specifically, the extension paths of the third section 1123 and the first section 1121 are connected and set at an angle. It should be noted that the third section 1123 is closer to the through hole 111 than the second section 1122. When the hanging column 120 is in the protruding position, such as... Figure 1 As shown, a rope is looped around the lifting column 120, driving the lifting column 120 to slide into the support frame 110 through the through hole 111. The protrusion 121 on the lifting column 120 slides from the end of the first segment 1121 near the through hole 111 to the end away from the through hole 111, sliding to the point where the third segment 1123 connects with the first segment 1121. Then, the lifting column 120 is rotated, causing the protrusion 121 to slide to the end of the third segment 1123 away from the first segment 1121. At this time, the lifting column 120 switches from a protruding position to a semi-protruding position. Figure 4 As shown, the lifting column 120 switches from a protruding position to a semi-protruding position, which shortens the length of the protrusion 121 relative to the support frame 110. During the lifting process, this reduces the swing distance of the rope on the lifting column 120, making the lifting process more stable.

[0028] In some implementations, the extension direction of the third segment 1123 may be the same as or opposite to the extension direction of the second segment 1122, and no specific limitation is made.

[0029] In some implementations, the first segment 1121 and the third segment 1123 can be set at an acute angle or a right angle, without limitation. For example... Figure 4As shown, the first segment 1121 and the third segment 1123 are set perpendicular to each other. Optionally, such as Figure 1 and Figure 2 As shown, a cover plate 122 is fixedly installed at the end of the lifting column 120 near the through hole 111. The cover plate 122 is provided with an extension ear 1221 protruding relative to the peripheral wall of the lifting column 120. The extension ear 1221 is used to limit the rope. Specifically, a cover plate 122 is provided on the lifting column 120, located at the end of the lifting column 120 near the through hole 111. An extension lug 1221 is provided on the cover plate 122, protruding from the peripheral wall of the lifting column 120. During lifting, the extension lug 1221 prevents the rope from slipping off the lifting column 120. Figure 2 As shown, when the hanging column 120 is in the retracted position, the extension direction of the extension ear 1221 is the same as or approximately the same as the length direction of the support frame 110. Figure 2 As shown, during the process of switching the hanging column 120 to the protruding position, the hanging column 120 is driven to rotate, so that the protrusion 121 on the hanging column 120 slides along the end of the second segment 1122 away from the first segment 1121 to the point of communication with the first segment 1121. At this time, the extension direction of the extension ear 1221 is the same as or approximately the same as the thickness direction of the support frame 110. Then the hanging column 120 is driven to make the protrusion 121 slide to the end of the first segment 1121 near the through hole 111, and the hanging column 120 is switched from the storage position to the protruding position.

[0030] Optionally, such as Figure 2 As shown, a receiving groove 113 is provided on the side of the support frame 110, and the opening of the through hole 111 is located at the bottom of the receiving groove 113. When the hanging column 120 is in the storage position, the cover plate 122 is set in the receiving groove 113.

[0031] Specifically, the side of the support frame 110 is provided with a receiving groove 113. When the hanging column 120 is switched from the protruding position to the storage position, the hanging column 120 slides into the support frame 110 through the through hole 111 at the bottom of the receiving groove 113. When the hanging column 120 is in the storage position, the cover plate 122 is set in the receiving groove 113, which prevents the cover plate 122 from protruding out of the support frame 110, which is beneficial to the storage and transportation of the support frame 110. Optionally, such as Figure 2 As shown, when the lifting column 120 is in the storage position, there is a gap between the cover plate 122 and the side of the support frame 110, and the extension direction of the extension ear 1221 is the same as the extension direction of the receiving groove 113. There is a gap between the cover plate 122 and the side wall of the receiving groove 113, and the rope is sleeved on the lifting column 120 through the gap. Specifically, such as Figure 2As shown, when the lifting column 120 is in the retracted position, there is a gap between the cover plate 122 and the side of the support frame 110, and a gap between the cover plate 122 and the side wall of the receiving groove 113. At this time, the extension direction of the extension ear 1221 is the same as the extension direction of the receiving groove 113. When preparing for lifting operations, the support frame 110 is placed on a horizontal plane. When the lifting column 120 is in the protruding position, as... Figure 1 As shown, the extension ear 1221 extends along the thickness direction of the bearing member, resulting in a small gap between the extension ear 1221 and the horizontal plane. This makes it difficult to loop the rope around the hanging column 120. Therefore, when the hanging column 120 is in the retracted position, as... Figure 2 As shown, the rope loop is fitted onto the hanging column 120 through the gap between the cover plate 122 and the side wall of the receiving groove 113. In order to prevent the rope loop from being subjected to the shearing force of the side wall of the receiving groove 113, the hanging column 120 needs to be switched from the storage position to the protruding position.

[0032] Optionally, such as Figure 1 and Figure 5 As shown, the support frame 110 includes a support plate 114 with a support surface, a frame 115, and a sleeve 116 for forming a through hole 111. The side of the support plate 114 facing away from the support surface is fixedly connected to the frame 115. The frame 115 is a mesh structure formed by multiple rods fixedly connected. The sleeve 116 is fixedly installed inside the frame 115, and the sliding groove 112 is installed in the sleeve 116. Specifically, the support frame 110 includes a support plate 114, a frame 115, and a sleeve 116. The support plate 114 has a bearing surface for bearing the heavy object to be lifted, and the side of the support plate 114 away from the bearing surface is fixedly connected to the frame 115. The frame 115 has a mesh structure, and the sleeve 116 is disposed inside the mesh structure frame 115, with the opening of the sleeve 116 forming a through hole 111. A sliding groove 112 is provided on the sleeve 116. The drive column 120 is slidably inserted into the sleeve 116 through the through hole 111, and drives the protrusion 121 to slide and engage with the sliding groove 112. The process of the drive column 120 switching from the protruding position to the retracted position has been explained above and will not be repeated here.

[0033] Optionally, through holes 111 are provided on opposite sides of the support frame 110, and a hanging column 120 is slidably inserted into each through hole 111, with the hanging columns 120 on opposite sides being coaxially arranged.

[0034] Specifically, through holes 111 for sliding insertion of the lifting columns 120 are provided on both opposite sides of the support frame, and the lifting columns 120 on opposite sides are coaxially arranged. By coaxially arranging the lifting columns 120, the support frame 110 can be prevented from rotating during the hoisting process, ensuring the stability of the hoisting process.

[0035] In some embodiments, the hoisting tool 100 includes at least four hoisting columns 120, which are arranged in a rectangular pattern at the four corners of the rectangle. The number of hoisting columns 120 can be six or eight or more, and there is no specific limitation. Each hoisting column 120 can switch between the protruding position and the storage position.

[0036] In another aspect of the embodiments of this application, a hoisting device is provided, including a drive member and the hoisting tool 100 described above, wherein the drive member is driven to be connected to the hoisting tool 100 via a rope.

[0037] Specifically, the lifting device includes a drive unit and a lifting tool 100. During lifting operations, the lifting column 120 is switched from a retracted position to a protruding position, and a telescopic sleeve is fitted onto the lifting column 120. The drive unit drives the lifting tool 100 to rise or fall via ropes. After the lifting operation is completed, the lifting column 120 is switched from the protruding position to the retracted position, and the lifting column 120 retracts relative to the support frame 110, facilitating the storage and transportation of the support frame 110.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
