The hoisting tool provided by the embodiment comprises a plug connector 100 for penetrating through a hoisting hole 610 in a plate body of a to-be-hoisted piece 600, a hoisting piece 200 for being connected with a hook or a hoisting rope of a crane or the like, and a barrier strip 300 for blocking the second end of the plug connector 100 at the corresponding side of the hoisting hole 610. Firstly, it should be noted that the hoisting tool of this embodiment is suitable for a plate-shaped piece 600 to be hoisted or a piece 600 to be hoisted including a plate body, a hoisting hole 610 for the insertion piece 100 of the hoisting tool to pass through is formed in the plate body, when the piece 600 to be hoisted needs to be hoisted, the barrier strip 300 is rotated to a position approximately consistent with the axial direction of the insertion piece 100, at this time, the barrier strip 300 and the insertion piece 100 are approximately linear strips, and at this time, the barrier strip 300 and the insertion piece 100 are in a dismounting position; the barrier strip 300 and the second end of the plug connector 100 penetrate through the hoisting hole 610, the barrier strip 300 is rotated to a position approximately perpendicular to the plug connector 100, the barrier strip 300 and the plug connector 100 are located at a locking position, the barrier strip 300 extends outwards along the radial direction of the plug connector 100, and the extending length of the barrier strip 300 is larger than that of the hoisting hole 610, so that the second end of the plug connector 100 is limited, and the situation that the second end of the plug connector 100 is pulled out of the hoisting hole 610 in the hoisting process is reduced; at this time, the lifting piece 200 is positioned at the other side of the lifting hole 610, and can limit the first end of the plug-in piece 100, so that the situation that the first end of the plug-in piece 100 is pulled out of the lifting hole 610 in the lifting process is correspondingly reduced; the barrier strip 300 and the hoisting limit the plug connector 100 to the hoisting hole 610 at this time, and then the hook or the lifting rope of the crane is connected with the hoisting piece 200 (after the first installation, in the process of hoisting the subsequent piece 600 to be hoisted by the crane, the hoisting piece 200 of the hoisting tool can be always connected with the hook or the lifting rope of the crane without repeated disassembly and assembly), and the piece 600 to be hoisted is hoisted and conveyed to a specified position by the hoisting tool.

After the hoisting is completed, only the barrier strip 300 needs to be rotated to the dismounting position, at the moment, the barrier strip 300 and the plug connector 100 are similar to a linear strip again, and then the second end of the plug connector 100 and the barrier strip 300 are pulled out from the hoisting hole 610, so that the hoisting of the to-be-hoisted piece 600 is completed. When this lifting device used, only need relative plug connector 100 to rotate blend stop 300 to dismouting position or locking position, can realize lifting device and treat the dismouting of hoisting piece 600, simple structure, the convenient degree of dismouting are higher, and corresponding improvement is treated the hoist and mount convenience and the hoist and mount efficiency of hoisting piece 600. In addition, when the hoisting tool is used, the position of the hoisting hole 610 on the piece 600 to be hoisted is not limited, the difficulty of arranging the hoisting hole 610 on the piece 600 to be hoisted is correspondingly reduced, and the workload of operators is reduced.

It should be noted that the hoisting hole 610 is in clearance fit with the plug connector 100, the depth of the plugging hole is close to the effective plugging length of the plug connector 100 between the hoisting member 200 and the barrier strip 300, and the expression "the length direction of the barrier strip 300 is the same as the axial direction of the plug connector 100" includes that the length direction of the barrier strip 300 and the axial direction of the plug connector 100 form an included angle of 0-5 degrees, so long as the plug connector 100 is inserted into or pulled out of the hoisting hole 610 along the dismounting position, the barrier strip 300 does not interfere with the hoisting hole 610; the phrase "the length direction of the barrier 300 is perpendicular to the axial direction of the plug connector 100" includes that the length direction of the barrier 300 forms an included angle of 85-90 degrees with the axial direction of the plug connector 100, as long as it is ensured that the barrier 300 can be tightly abutted against the side wall of the piece 600 to be hoisted in the hoisting process, and the second end of the plug connector 100 is limited to the side of the piece 600 to be hoisted. In addition, the "first end portion" of the connector 100 includes a first end surface of the connector 100 and a segment of the connector 100 near the end surface; similarly, the "second end" of the connector 100 includes the second end face of the connector 100 and a segment of the connector 100 adjacent to the end face.

Alternatively, in this embodiment, as shown in fig. 2 and fig. 3, two opposite supporting arms 400 may be disposed at the second end of the plug 100 and extend along the axial direction of the plug 100, a rotating space 410 is formed between the two supporting arms 400, a rotating shaft 420 is connected between the two supporting arms 400, and a distance between the rotating shaft 420 and the root of the supporting arms 400 is a rotating radius; as shown in fig. 1, 4 and 5, the barrier bar 300 is provided with a rotation hole 321, the blocking sections of the barrier bar 300 corresponding to the rotation hole 321 are the adjusting portions 320, the blocking sections of the barrier bar 300 located at two sides of the adjusting portion 320 are the first blocking portion 310 and the second blocking portion 330 respectively, the adjusting portion 320 is located between the two support arms 400, the rotation shaft 420 is rotatably inserted into the rotation hole 321, and the length of at least one of the first blocking portion 310 and the second blocking portion 330 is smaller than the rotation radius.

Here, in a specific form of the rotational connection between the barrier 300 and the plug 100, the plug 100 and the adjusting portion 320 can rotate relatively by the engagement of the rotating shaft 420 and the rotating hole 321, and the length of at least one of the first blocking portion 310 and the second blocking portion 330 is smaller than the rotating radius, for example, the length of the second blocking portion 330 is smaller than the rotating radius; when the lifting device is used, the barrier strip 300 can be rotated, because the length of the second barrier part 330 is smaller than the rotation radius, the second barrier part 330 can be completely rotated to the rotation space 410 between the rotating shaft 420 and the root of the supporting arm 400 (the connecting end part of the supporting arm 400 and the plug connector 100), the barrier strip 300 can be correspondingly rotated to the dismounting position, and then the plug connector 100 and the barrier strip 300 can be inserted into the lifting hole 610 of the to-be-lifted piece 600; then, the barrier 300 is rotated to the locking position, the barrier 300 is approximately perpendicular to the plug connector 100, and at least one of the first barrier 310 and the second barrier 330 extends outward along the radial direction of the plug connector 100, or the position of the adjusting portion 320 is adjusted so that at least one of the first barrier 310 and the second barrier 330 extends outward along the radial direction of the plug connector 100, thereby limiting the second end of the plug connector 100 by the barrier 300. After the hoisting of the to-be-hoisted piece 600 is completed, the barrier strip 300 is rotated to the dismounting position again, and the barrier strip 300 and the plug connector 100 are pulled out from the hoisting hole 610, so that the to-be-hoisted piece 600 is hoisted.

Of course, the above operation process is only described by taking the example that the length of the second blocking portion 330 is smaller than the rotation radius, in some embodiments, the length of the first blocking portion 310 may also be smaller than the rotation radius, and only one of the first blocking portion 310 and the second blocking portion 330 needs to be ensured to be able to rotate to the rotation space 410 between the rotation shaft 420 and the support shaft root, so as to enable the blocking strip 300 to reach the dismounting position; and when the barrier strip 300 rotates to the locking position, at least one of the first barrier portion 310 and the second barrier portion 330 can be ensured to extend outward along the radial direction of the plug 100, so as to limit the second end of the plug 100. Preferably, the plug 100 and the support arm 400 are integrally formed.

Specifically, in this embodiment, the length of the first blocking portion 310 may be greater than the rotation radius, and when the blocking strip 300 rotates to the locking position, the first blocking portion 310 protrudes out of the plug connector 100 along the radial direction of the plug connector 100. As can be seen from the above limitation and analysis, when the length of the first blocking portion 310 is greater than the rotation radius, the length of the second blocking portion 330 is necessarily smaller than the rotation radius, and the second blocking portion 330 can be rotated to the rotation space 410 between the rotation shaft 420 and the root of the support arm 400, so as to rotate the barrier strip 300 to the dismounting position, thereby realizing the dismounting operation of the plug connector 100 and the barrier strip 300 relative to the hoisting hole 610; or the barrier strip 300 is rotated to the locking position, at least the first barrier portion 310 extends outward along the radial direction of the connector 100, so as to limit the second end of the connector 100.

Specifically, in this embodiment, as shown in fig. 1, fig. 4 and fig. 5, the rotation hole 321 may be a kidney-shaped hole extending along the length direction of the barrier strip 300, and when one end of the rotation hole 321 close to the first blocking portion 310 is engaged with the rotation shaft 420, the sum of the length of the hole of the rotation shaft 420 away from the first blocking portion 310 and the length of the second blocking portion 330 is greater than the rotation radius of the rotation hole 321. The length of the first blocking part 310 is larger than the rotation radius, the length of the second blocking part 330 is smaller than the rotation radius, and the distance between the rotating shaft 420 and the first blocking part 310 and the distance between the rotating shaft 420 and the second blocking part 330 can be adjusted along the length extending direction of the rotating hole 321 on the basis that the rotating shaft 420 and the rotating hole 321 in the form of the kidney-shaped hole are in rotating fit; when the connector is used, the position of the rotating shaft 420 in the rotating hole 321 can be adjusted, so that the rotating shaft 420 is in rotating fit with one end of the rotating hole 321 close to the second blocking part 330, then the blocking strip 300 is rotated, so that the second blocking part 330 rotates to the rotating space 410 between the rotating shaft 420 and the root of the support arm 400, the blocking strip 300 is rotated to the dismounting position, and then the connector 100 and the blocking strip 300 are inserted into the hoisting hole 610; then, the barrier 300 is rotated to a position approximately perpendicular to the plug connector 100, and the position of the rotating shaft 420 in the rotating hole 321 is adjusted along the length direction of the barrier 300, so that the rotating shaft 420 is matched with one end of the rotating hole 321 close to the first barrier 310, because the sum of the length of the hole body of the rotating shaft 420 departing from the first barrier 310 and the length of the second barrier 330 in the rotating hole 321 is greater than the rotating radius, when the rotating shaft 420 is matched with the end of the rotating hole 321, the second barrier 330 cannot rotate into the rotating space 410 between the rotating shaft 420 and the root of the supporting arm 400, because the first barrier 310 is greater than the rotating radius, the first barrier 310 cannot rotate into the rotating space 410 between the rotating shaft 420 and the root of the supporting arm 400, that is, both ends of the barrier 300 cannot rotate to the dismounting position axially consistent with the plug connector 100, the barrier 300 is in the locking state at this time, and because at least the first barrier 310 can extend outward from the plug connector 100 to limit the axial movement of the second end of the plug connector 100 at this time, the blocking strip 300 can stably lock the second end of the plug connector 100 to the side of the lifting hole 610, and accordingly, the occurrence of the situation that the plug connector 100 falls off from the lifting hole 610 in the lifting process due to the fact that one end of the blocking strip 300 can rotate relative to the plug connector 100 to enable the blocking strip 300 to reach the dismounting position is effectively reduced.

Preferably, when the rotating shaft 420 and the one end that the rotation hole 321 is close to the first blocking portion 310 are in running fit, and the blocking strip 300 is in the locking position, the first blocking portion 310 and the second blocking portion 330 can both extend outward along the radial direction of the plug connector 100, then both ends of the blocking strip 300 can not be rotated to the dismounting position, and both ends of the blocking strip 300 can be both limited by the edge of the hoisting hole 610 and the butt of the plate body to be hoisted, the axial movement of the second end of the plug connector 100 is limited, thereby further ensuring the hoisting process, the locking stability and firmness of the plug connector 100 and the hoisting hole 610, and accordingly ensuring the smooth and safe operation of hoisting.

The barrier strip 300 can adopt other forms besides the above form of a waist-shaped hole, on the basis of realizing the rotation of the barrier strip 300 between the dismounting position and the locking position, the limit stability of the barrier strip 300 on the axial movement of the second end of the plug-in connector 100 can be ensured, for example, one end of the barrier strip 300 is hinged with the second end of the plug-in connector 100, the hinge resistance of the shaft holes of the barrier strip 300 and the second end of the plug-in connector 100 is larger, when the barrier strip 300 rotates to the locking position, the barrier strip 300 can not rotate relative to the barrier strip 300 when being subjected to external force in a certain range, thereby realizing the limit locking on the axial movement of the second end of the limiting part; or the one end of blend stop 300 is articulated with the second end of plug connector 100, install the piece that resets such as torsional spring between the two, should reset the piece and can drive blend stop 300 and rotate towards plug connector 100, during the use, can drive blend stop 300 hard and rotate to dismouting position, plug connector 100 and blend stop 300 insert behind hole for hoist 610, blend stop 300 can rotate to locking position under the reset action that resets, the plate body butt at blend stop 300 and hole for hoist 610 edge, the realization is to spacing locking etc. of locating part second end axial motion.

Specifically, in this embodiment, as shown in fig. 5, two bar-shaped arms 322 may be disposed at one end of the first blocking portion 310, a stop 331 is detachably fixed between the two bar-shaped arms 322, and the stop 331 is located at one end of the two bar-shaped arms 322 that is away from the first blocking portion 310, where the stop 331 is used as the second blocking portion 330, and the first blocking portion 310, the bar-shaped arms 322, and the stop 331 enclose the rotation hole 321. It is a concrete form of constituting of rotation hole 321 in blend stop 300 here, because blend stop 300 rotates wearing and tearing and blend stop 300 and treats that the spacing damage that leads to of hoist and mount piece 600 butt is great, when need to be changed blend stop 300, can pull down dog 331, then take out blend stop 300 from the open end of two bar arms 322, insert pivot 420 through the open end of bar arm 322 with new blend stop 300 afterwards, and connect new dog 331 in the open end of bar arm 322, can realize the change to blend stop 300 through comparatively convenient operation, thereby improve hoisting tool's use and later maintenance's convenience. Of course, in other embodiments, as shown in fig. 4, the barrier strip 300 may be formed integrally, and the barrier strip 300 may be provided with a rotation hole 321 in the form of a kidney-shaped hole. Specifically, the stop 331 and the two bar-shaped arms 322 can be detachably fixed by screws.

Alternatively, in this embodiment, as shown in fig. 2 and 3, a receiving hole 110 may be provided at the second end of the plug 100, and the diameter of the receiving hole 110 is larger than the radial dimension of the barrier 300. When the hoisting tool is needed, the rotating shaft 420 can be moved to the end part of the rotating hole 321 close to the second blocking part 330, the second blocking part 330 of the blocking strip 300 is rotated into the rotating space 410 between the rotating shaft 420 and the root part of the supporting shaft, then the blocking strip 300 is moved towards the accommodating hole 110 along the axial direction of the plug connector 100, the rotating shaft 420 correspondingly moves towards the first blocking part 310 along the length direction of the rotating hole 321, and the second blocking part 330 of the blocking strip 300 is inserted into the accommodating hole 110; on the other hand, when the barrier strip 300 is located the dismouting position, the whole length of plug connector 100 and barrier strip 300 shortens, can further improve the convenient degree that plug connector 100 and barrier strip 300 inserted hoisting hole 610, the convenient degree of installation of corresponding lifting device that improves. The bar 300 may then be pulled out of the receiving hole 110, the bar 300 may be rotated to be approximately perpendicular to the connector 100, and the bar 300 may be adjusted such that the rotation shaft 420 moves to the end of the rotation hole 321 near the first stopping portion 310, thereby achieving the locking of the bar 300 to the connector 100. When the hoisting tool is disassembled, the installation operation can be similarly adopted, and the details are not repeated.

Specifically, in the present embodiment, the plug 100 may be in the form of a sleeve. When the plug connector 100 is in a sleeve form, the accommodating hole 110 penetrates through the plug connector 100 along the axial direction, in the assembling and disassembling process, on the basis that the length of the plug connector 100 is not limited, the accommodating hole 110 does not limit the depth of the barrier strip 300 inserted into the accommodating hole, and the barrier strip 300 can be fully inserted into the accommodating hole 110, so that the limiting stability of the assembling and disassembling position of the barrier strip 300 by the accommodating hole 110 is ensured, and the length of the whole formed by the plug connector 100 and the barrier strip 300 is shortened as much as possible. In addition, compared with the method that a counter bore with one closed end is formed in one end of the plug connector 100, the sleeve is selected as the plug connector 100, and the processing convenience and the strength of the plug connector 100 are higher.
