[0029] The present application will be further described below in combination with the drawings and specific embodiments. It should be noted that the description of these embodiment modes is used to help understand the present application, and does not constitute a limitation on the present application. The specific structure and functional details disclosed herein are only used to describe the example embodiments of the present application. However, the present application can be embodied in many alternative forms, and should not be understood as being limited in the embodiments described herein.

[0030] As Figs. 1-6As shown, the lying roll clamp provided in the present application comprises a driving device 6, a clamp hook 7, a lifting belt and an auxiliary removal tool, the driving device 6 is connected with the clamp hook 7 and drives the clamp hook 7 to move, the clamp hook 7 is provided with a groove 71, the main body 1 is arranged on the clamp hook 7, and the clamping block 11 extends into the groove 71, the traction part 3 is connected with the driving device 6 at one end away from the guide plate 2, and the end of the lifting belt is used for hanging on the guide plate 2.

[0031] Before and after the lying roll is transported, the axes of a plurality of lying rolls are coincident and placed, and the lying roll axis is in a horizontal state, the lying roll clamp main body 1 is connected with the lifting frame, and the lying roll clamp is driven by the lifting frame to move as a whole, wherein the driving device 6 can adopt a driving motor, and the opening and closing actions of the two clamp hooks 7 can be realized through a set of gear and rack transmission mechanisms, the two clamp hooks 7 are close to each other from the opening state, and after the two ends of the lifting belt are hooked, the lying roll clamp is lifted under the driving of the lifting frame, and the lying roll is lifted by the lifting belt to work.

[0032] An opening is formed between the two clamp hooks 7, and in the process of lifting the lying roll, the opening is used to facilitate the relative movement of the lying roll to between the two clamp hooks 7, because the two ends of the lifting belt are hooked on the two clamp hooks 7 respectively, that is, the opening between the two clamp hooks 7 is connected by the lifting belt, and under the premise that the lifting belt is not disassembled, the lying roll cannot be separated from the clamp hook 7.

[0033] In order to avoid the need for manual separation of the lifting belt from the clamp hook 7, an auxiliary removal tool is arranged between the clamp hook 7 and one end of the lifting belt, which replaces the manual removal of the end of the lifting belt.

[0034] The above-mentioned auxiliary removal tool for the lifting belt of the steel roll comprises a main body 1, a guide plate 2 and a traction part 3, wherein:

[0035] The main body 1 is used for being arranged on the clamp hook 7, and the main body 1 is further provided with a clamping block 11 for being hooked on the clamp hook 7, the main body 1 extends into the groove 71 on the clamp hook 7 through the clamping block 11, the relative positional relationship between the main body 1 and the clamp hook 7 is maintained, and the main body 1 stably follows the synchronous movement of the clamp hook 7.

[0036] The guide plate 2 is movably arranged on the main body 1, and a rotating device 21 is arranged between the guide plate 2 and the main body 1.

[0037] The rotating device 21 can be a hinge, a pin shaft or a shackle, and can also be other connecting devices, so that the guide plate 2 rotates relative to the main body 1 around the rotating device 21.

[0038] It is worth noting that, due to the fact that the one end of the sling is hung on the guide plate 2, when the middle part of the sling is hung with the lying roll, under the action of the gravity of the lying roll, the force of the sling on the guide plate 2 is vertically downward, the guide plate 2 is arranged on the main body 1, and through the transmission of the force, the force of the main body 1 on the clamp hook 7 is also vertically downward, that is to say, in the process of hoisting, the main body 1 will not be separated from the clamp hook 7, even in the process of separating the sling from the guide plate 2, the mutual constraint of the clamping block 11 and the groove 71 makes the main body 1 and the clamp hook 7 maintain a stable relative relationship.

[0039] The one end of the traction part 3 is connected with the one end of the guide plate 2 away from the rotating device 21, and the other end of the traction part 3 is connected on the driving device 6.

[0040] The traction part 3 can be a rope, which is used to rotate the guide plate 2 relative to the main body 1.

[0041] In order to facilitate the connection between the traction part 3 and the guide plate 2, a connecting ring 22 can be arranged on the guide plate 2, which improves the convenience of connecting the traction part 3.

[0042] Since the driving device 6 is relatively static relative to the clamp hook 7, the clamp hook 7 is in a motion state of approaching or moving away from the driving device 6, when the one end of the traction part 3 is connected with the driving device 6, the connecting end of the guide plate 2 will be pulled by the traction part 3, and then the guide plate 2 forms a relative rotation with the main body 1 through the rotating device 21, at this time, the top surface of the guide plate 2 supporting the sling is in an inclined state, which is convenient for the sling to slide off and separate from the guide plate 2, and forms the dismounting of the one end of the sling.

[0043] The working principle of the embodiment is as follows: when the auxiliary dismounting tool for the steel roll sling is used, the main body 1 is arranged on the clamp hook 7, the clamping block 11 on the main body 1 is hooked on the clamp hook 7, which prevents the main body 1 from sliding off the clamp hook 7, at this time, the sling is hung on the guide plate 2 on the main body 1, one end of the traction part 3 is connected with the guide plate 2, and the other end is connected with the driving device 6 of the lying roll clamp, then the steel roll is hoisted by the lying roll clamp, after the steel roll is hoisted to the target position, the steel roll is placed, the sling no longer hoists the steel roll, the clamp hook 7 of the lying roll clamp is separated from the steel roll, at this time, the traction part 3 pulls one end of the guide plate 2, through the rotating device 21 between the guide plate 2 and the main body 1, the guide plate 2 rotates by a certain angle, and then the one end of the sling slides off from the guide plate 2 under the action of gravity, which realizes the separation from the clamp hook 7, the whole process does not need manual intervention for the dismounting operation of the steel roll sling, the safety is high, and the hoisting device and the lying roll clamp do not need repeated operation, which improves the operation efficiency.

[0044] Further, referring to Figs. 1-4On the basis of the above-mentioned embodiments, the auxiliary dismounting tool further comprises a locking device, which is rotationally connected between the main body 1 and is used for locking with the clamp hook 7.

[0045] During the lifting process, even if the lifting belt is separated from the guide plate 2, the mutual constraint between the clamping block 11 and the groove 71 ensures that the main body 1 and the clamp hook 7 maintain a stable relative relationship. However, if the connection end of the lifting belt and the clamp hook 7 rotates and deviates along the center line of the steel coil, the main body 1 will move along the length extension direction of the groove 71, and there is a risk of separation between the main body 1 and the clamp hook 7 to a certain extent. By locking the main body 1 on the clamp hook 7 through the locking device, and rotationally connecting the locking device and the main body 1, it is convenient to separate the clamp hook 7 and complete disassembly after the locking device is rotated and opened. The locking device and the main body 1 can be connected by a hinge. In addition, when the specifications of the clamp hook 7 are inconsistent, that is, when the width of the clamp hook 7 is different, the locking device can be rotated to different degrees to meet the different specification requirements of the clamp hook 7, thereby improving the applicability.

[0046] Further, referring to Figs. 1-4 On the basis of the above-mentioned embodiments, the locking device comprises a constraint part 41 and two rotating arms 42, one end of each of the two rotating arms 42 is rotationally connected on both sides of the main body 1, and the constraint part 41 is connected with the other end of the two rotating arms 42 at the same time to limit the separation of the ends of the two rotating arms 42 away from the main body 1.

[0047] When the locking device is installed and locked, the two rotating arms 42 rotate relative to the main body 1 until the rotating arms 42 are buckled on both ends of the clamp hook 7, and the rotating arms 42 are limited from being separated by the constraint part 41, forming a ring-shaped locking of the clamp hook 7 by the two rotating arms 42. Anti-skid strips can also be provided on the side walls of the rotating arms 42 close to the clamp hook 7 to increase the friction and prevent the clamp hook 7 from being worn.

[0048] It is worth noting that under the premise of being clamped by the two rotating arms 42, rollers for buffering can be provided on both sides of the end of the clamp hook 7. When the two clamping arms are buckled on both sides of the clamp hook 7 and are constrained by the constraint part 41, the rollers on both sides can also limit the movement of the clamping arms parallel to the coil shaft, further improving the stability.

[0049] Further, on the basis of the above-mentioned embodiments, the ends of the two rotating arms 42 away from the main body 1 are respectively provided with a constraint hole 43, and the constraint part 41 is detachably connected with the rotating arms 42 through the constraint hole 43.

[0050] The constraint part 41 can be a bolt or a lock.

[0051] In the assembly, the bolt or lock is simultaneously inserted through the constraint holes 43 on the two swing arms 42, limiting the swing arms 42 from unfolding again, improving the operation convenience, and improving the stability of the connection between the main body 1 and the clamp hook 7.

[0052] Further, on the basis of the above-mentioned embodiments, the swing arm 42 is provided with a side plate 5.

[0053] The top surface of the guide plate 2 supporting the sling is inclined, facilitating the separation of the sling from the guide plate 2, and forming the dismounting of one end of the sling. The side plate 5 is additionally provided on the swing arm 42 to smoothly separate the two sides of the sling end from the clamp hook 7, and the side plate 5 forms the guide component of the two sides of the sling, avoiding unnecessary hooking of the sling.

[0054] Further, on the basis of the above-mentioned embodiments, the guide plate 2 is arc-shaped, improving the smoothness and fluency of the guiding effect on the two sides of the sling.

[0055] Further, on the basis of the above-mentioned embodiments, the outer wall of the guide plate 2 for supporting the sling has a convex pattern, improving the friction between the guide plate 2 and the sling, and avoiding the separation of the sling from the guide plate 2 due to the sliding of the sling on the guide plate 2 in the non-inclined state of the guide plate 2.

[0056] Further, on the basis of the above-mentioned embodiments, when the sling is used to hoist the lying roll, the minimum breaking force of the traction part 3 is less than the pressure of the sling on the guide plate 2. That is, when the lying roll is hoisted on the sling, the gravity of the lying roll causes the sling to press on the guide plate 2. If the clamp hook 7 is mistakenly opened, that is, the lying roll is not placed, the clamp hook 7 is separated from each other. At this time, the traction part 3 will still normally pull the guide plate 2 to incline, causing the sling to accidentally fall off. There is a great security risk due to the mistaken operation.

[0057] When the minimum breaking force of the traction part 3 is less than the pressure of the sling on the guide plate 2, and the clamp hook 7 is mistakenly opened, because the pressure of the sling on the guide plate 2 is large, the structural strength of the traction part 3 is insufficient to pull the guide plate 2 to incline. In the process of continuous separation of the clamp hook 7, the traction part 3 will be pulled off, avoiding the inclination and separation of the guide plate 2 from the sling, and improving the safety.
