Description

Technical Field

[0001] The invention relates to the field of hoisting equipment, in particular to a self-detachable shackle realized by using an electric motor. Background Art

[0002] When lifting heavy equipment from a height, it is often difficult to remove the slings and shackles used in the lifting process because the heavy equipment is in a high position after lifting. The commonly used solutions currently include using a ladder or workers tying safety ropes to remove the slings and shackles, which are costly and have high operational risks. Some electric shackle solutions have been proposed in the power industry for lifting cables, etc., but they have caused a certain degree of modification to the structure of the shackle itself, weakening the strength of the shackle. They are suitable for lifting lighter items such as cables, but not for lifting heavy equipment, because heavy equipment has high reliability requirements for the shackle, and it is not suitable for structural modifications to the shackle itself.

[0006] The present invention utilizes a motor to realize a self-detachable shackle, wherein a first support plate is fixedly arranged at one end of the shackle body, the motor is slidably arranged on the first support plate, and the first nut is fixedly arranged on the first support plate.

[0007] The present invention utilizes an electric motor to realize a self-detachable shackle, wherein two second support plates opposite to each other and arranged at intervals are fixedly provided on one side of the first support plate, the motor is slidably arranged between the two second support plates, and the first nut is fixedly arranged between the two second support plates.

[0008] The present invention utilizes an electric motor to realize a self-detachable shackle, wherein two second support plates are respectively provided with a slide groove on their opposite sides, and the slide groove is arranged in a direction from one end of the shackle body to the other end, and two sliders are fixedly provided on the motor, and the two sliders are respectively located on opposite sides of the motor, and the two sliders are respectively slidably connected in the two slide grooves.

[0010] The present invention utilizes an electric motor to realize a self-detachable shackle, wherein the nut box comprises a box body and a box cover, the box body is in a cylindrical shape, the barrel cavity of the box body comprises a first sub-barrel cavity and a second sub-barrel cavity which are interconnected, the cross-section of the first sub-barrel cavity is a polygon matching the outer circumferential surface of the second nut, the second nut is located in the first sub-barrel cavity, the cross-section of the second sub-barrel cavity is circular, the box cover is in a cylindrical shape matching the second sub-barrel cavity, the box cover is inserted in the second sub-barrel cavity, one end of the box body close to the first sub-barrel cavity is fixedly arranged on the other end of the shackle body, and the barrel cavity of the box body is arranged along the direction from one end to the other end of the shackle body.

Since the locking rod is threadedly connected to the first nut, and the first nut is fixed to one end of the shackle body, the locking rod rotates relative to the first nut and drives the motor to slide close to the shackle body until the locking rod passes through the through holes at both ends of the shackle body and is threadedly connected to the second nut (since the second nut is restricted in the nut box and cannot rotate, the locking rod can be threadedly connected to the second nut).

[0026] like Figure 1 As shown, combined with Figure 2-10 As shown in the figure, the self-detachable shackle realized by the motor of the present invention comprises a U-shaped shackle body 4, which is a prior art, and has a through hole 19 at each end. In this embodiment, the two ends of the shackle body 4 are downwardly facing as an example, and the two ends are arranged opposite to each other in the horizontal direction. One end of the shackle body 4 (i.e. Figure 1 , 6 , the left end shown in 8-10) is provided with a motor 3 that can slide close to or away from the shackle body 4, one end of the shackle body 4 is also fixed with a first nut 9, the first nut 9 is located between the motor 3 and the shackle body 4, and a coaxially arranged locking rod 5 is fixed on the output end of the motor 3, the locking rod 5 is threadedly connected in the first nut 9, and the other end of the shackle body 4 (i.e. Figure 1 , 6 , the right end shown in 8-10) is fixedly provided with a nut box 8, and a second nut 14 is installed in the nut box 8. When the motor 3 drives the locking rod 5 to rotate, the motor 3 can slide close to the shackle body 4 to make the locking rod 5 pass through the through holes 19 at both ends of the shackle body 4 and then be threadedly connected with the second nut 14.

[0027] The locking rod 5 and the output end of the motor 3 can be fixed by welding or mechanical connection, as long as the locking rod 5 can be fixed to the output end of the motor 3. The diameter of the locking rod 5 is smaller than the diameter of the through holes 19 at both ends of the shackle body 4. When the locking rod 5 passes through the through holes 19 at both ends of the shackle body 4, the locking rod 5 does not contact the hole wall of the through hole 19, that is, at this time, the locking rod 5 and the through hole 19 are clearance fit.

[0028] The nut box 8 is a hollow box, which is welded on the shackle body 4 to provide constraints on the second nut 14, preventing the second nut 14 from rotating simultaneously with the locking rod 5, and also preventing the second nut 14 from falling from a height after high-altitude disassembly is completed, thereby eliminating safety hazards.

[0029] The locking rod 5 and the second nut 14 use bolts and nuts matched with the shackle body 4, and do not cause structural damage to the main load-bearing parts of the shackle.

[0030] When the present invention is in use, when the shackle changes from an unlocked state to a locked state, the motor 3 is turned on to drive the locking rod 5 to rotate forwardly. Since the locking rod 5 is threadedly connected to the first nut 9, and the first nut 9 is fixed to one end of the shackle body 4, the locking rod 5 rotates relative to the first nut 9 and drives the motor 3 to slide close to the shackle body 4 until the locking rod 5 passes through the through holes 19 at both ends of the shackle body 4 and is threadedly connected to the second nut 14 (since the second nut 14 is restricted in the nut box 8 and cannot rotate, the locking rod 5 can be threadedly connected to the second nut 14). When the shackle is in a locked state, the heavy equipment can be hoisted; after the hoisting is completed, when the shackle is unlocked, the motor 3 drives the locking rod 5 to rotate in the opposite direction, so that the locking rod 5 gradually withdraws from the second nut 14. During this process, the locking rod 5 drives the motor 3 to slide in the direction away from the shackle body 4. After the locking rod 5 completely withdraws from the second nut 14, under the action of the first nut 9, the locking rod 5 continues to drive the motor 3 to slide in the direction away from the shackle body 4 until the end of the locking rod 5 withdraws from between the two ends of the shackle body 4. At this time, the shackle is in an unlocked state, and the disassembly of the shackle and the sling is completed. It can be seen that the present invention belongs to a self-detachable shackle, which can be automatically locked and unlocked by the motor 3, and can be used in occasions where it is difficult to disassemble the shackle sling after the heavy equipment is hoisted at high altitude, and is used to complete the disassembly of the shackle after the heavy equipment is hoisted at high altitude.

[0031] like Figure 1 , 6 As shown in 8-10, the present invention uses a motor to realize a self-detachable shackle, wherein the locking rod 5 includes a smooth rod portion 6 arranged close to the motor 3 and a threaded portion 7 arranged away from the motor 3, that is, the end of the locking rod 5 close to the motor 3 is the smooth rod portion 6, and no thread is arranged on its outer circumference, while the end away from the motor 3 is the threaded portion 7, and thread is arranged on its outer circumference. The threaded portion 7 is connected to the first nut 9. When the motor 3 drives the locking rod 5 to rotate, the motor 3 can slide close to the shackle body 4 so that the threaded portion 7 of the locking rod 5 passes through the through holes 19 at both ends of the shackle body 4 and is threadedly connected to the second nut 14. The length of the threaded portion 7 is equal to or slightly greater than the distance between the first nut 9 and the second nut 14.

[0032] When the shackle changes from the unlocked state to the locked state, Fig.10As shown, the end of the locking rod 5 is not between the two ends of the shackle body 4. At this time, the shackle is in an unfastened state. The motor 3 is turned on to drive the locking rod 5 to rotate in the forward direction. Since the threaded portion 7 of the locking rod 5 is threadedly connected with the first nut 9, and the first nut 9 is fixed to one end (i.e., the left end) of the shackle body 4, the locking rod 5 rotates relative to the first nut 9 and drives the motor 3 to slide close to the shackle body 4 (i.e., slide from left to right). After that, the end of the locking rod 5 first passes through the through hole 19 at one end (i.e., the left end) of the shackle body 4, and then passes through the through hole 19 at the other end (i.e., the right end) of the shackle body 4, and finally enters the nut box 8 and contacts the second nut 14, as shown in FIG. Fig. 9 As shown, since the length of the threaded portion 7 is equal to or slightly larger than the spacing between the first nut 9 and the second nut 14, when the end of the locking rod 5 (i.e., the end of the threaded portion 7 away from the smooth rod 6, i.e., the right end as shown) contacts the second nut 14, the end of the threaded portion 7 close to the smooth rod 6 (i.e., the left end) is separated from the first nut 9. At this time, the smooth rod 6 is located in the first nut 9 and the two are not in contact (i.e., the inner diameter of the first nut 9 is larger than the diameter of the smooth rod 6, and there is a clearance fit between the two). In this way, when the end of the locking rod 5 is screwed into the second nut 14, the first nut 9 will not hinder the locking rod 5. Afterwards, as the locking rod 5 continues to rotate, the end of the locking rod 5 is screwed into the second nut 14, as shown in FIG. Figure 8 As shown, the shackle is in a locked state at this time.

[0033] When the shackle changes from the locked state to the unlocked state, Figure 8 As shown, the end of the locking rod 5 (i.e., the end of the threaded portion 7 away from the smooth rod portion 6, i.e., the right end in the figure) is threadedly connected in the second nut 14, and the end of the threaded portion 7 close to the smooth rod portion 6 (i.e., the left end) is not connected to the first nut 9, and the smooth rod portion 6 is located in the first nut 9. At this time, the shackle is in a locked state, and the motor is turned on to drive the locking rod 5 to rotate in the opposite direction. Since the second nut 14 is restricted by the nut box 8, the locking rod 5 rotates relative to the second nut 14 and drives the motor 3 to slide in the direction away from the shackle body 4 (i.e., slide from right to left) until the end of the locking rod 5 exits the second nut 14. Fig. 9 As shown, since the length of the threaded portion 7 is equal to or slightly larger than the spacing between the first nut 9 and the second nut 14, when the end of the locking rod 5 exits the second nut 14, the end of the threaded portion 7 close to the smooth rod portion 6 (i.e., the left end) is just screwed into the first nut 9, so that the locking rod 5 rotates relative to the first nut 9 and continues to drive the motor 3 to slide in the direction away from the shackle body 4 until the end of the locking rod 5 exits between the two ends of the shackle body 4, as shown in FIG. Fig.10 As shown, the shackle is in the released state at this time.

[0034] When the present invention is used, the shackle is first placed in an unfastened state so that the sling and the object to be hoisted can be installed. After the installation is completed, the shackle can be changed from the unfastened state to the locked state, and then hoisting can be carried out. After the hoisting is completed, the shackle is changed from the locked state to the unfastened state, and the sling and the object to be hoisted can be disassembled.

[0035] like Figure 1 , 2 6-10, the present invention uses a self-detachable shackle realized by a motor, wherein one end of the shackle body 4 is fixedly provided with a first support plate 1, the motor 3 is slidably provided on the first support plate 1, and the first nut 9 is fixedly provided on the first support plate 1. Specifically, two second support plates 2 that are opposite and spaced are fixedly provided on one side of the first support plate 1, the motor 3 is slidably provided between the two second support plates 2, and the first nut 9 is fixedly provided between the two second support plates 2.

[0036] like Figure 1 , 6 As shown in , 8-10, the first support plate 1 is a strip plate arranged in the horizontal direction, one end (i.e., the right end) of the first support plate 1 is fixedly arranged at one end (i.e., the left end) of the shackle body 4, and the other end (i.e., the left end) of the first support plate 1 extends in a direction away from the shackle body 4. Two second support plates 2 are fixedly arranged on the lower side of the first support plate 1, and the two second support plates 2 are arranged perpendicular to the first support plate 1. The two second support plates 2 are both strip plates, and the length direction of the two second support plates 2 and the first support plate 1 is the horizontal direction from left to right.

[0037] like Figure 6 , 7 As shown in 8-10, the specific manner in which the motor 3 is slidably arranged between the two second support plates 2 is as follows: a slide groove 17 is respectively arranged on the sides of the two second support plates 2 that are opposite to each other, and the slide groove 17 is arranged in the direction from one end to the other end of the shackle body 4, that is, the slide groove 17 is arranged in the horizontal direction from left to right, that is, it is arranged along the length direction of the second support plate 2, and two sliders 18 are fixedly arranged on the motor 3, and the two sliders 18 are respectively located on the opposite sides of the motor 3, and the two sliders 18 are respectively slidably connected in the two slide grooves 17. In this way, when the motor 3 slides from left to right along the slide groove 17 through the slider 18, the motor 3 slides close to the shackle body 4, and conversely, when the motor 3 slides from right to left along the slide groove 17 through the slider 18, the motor 3 slides away from the shackle body 4.

[0038] Of course, in addition to the above-mentioned method of sliding the motor 3 between the two second support plates 2, the positions of the slider 18 and the slide groove 17 can also be swapped, that is, a strip slider is respectively provided on the opposite sides of the two second support plates 2, and the strip slider is arranged along the direction from one end of the shackle body 4 to the other end, that is, the strip slider is arranged along the horizontal direction from left to right, that is, it is arranged along the length direction of the second support plate 2, and the motor 3 is provided with two slide grooves, and the slide grooves are also arranged along the direction from one end of the shackle body 4 to the other end. The two slide grooves are respectively located on the opposite sides of the motor 3, and the two strip sliders are respectively slidably connected in the two slide grooves. When setting the slide groove on the motor 3, the slide grooves can be respectively set on the two fixed blocks first, and then the two fixed blocks can be respectively fixed on the opposite sides of the motor 3.

[0039] In order to prevent the motor 3 from slipping off the two second support plates 2 during the sliding process, when the slide groove 17 is arranged on the second support plate 2, stoppers can be respectively arranged at both ends of the slide groove 17; when the strip slider is arranged on the second support plate 2, stoppers can be respectively arranged at both ends of the strip slider.

[0040] like Figure 1 , 3 -6, the present invention uses a self-detachable shackle realized by an electric motor, wherein the nut box 8 includes a box body 11 and a box cover 12, the box body 11 is cylindrical, the barrel cavity of the box body 11 includes a first sub-barrel cavity 13 and a second sub-barrel cavity 16 that are interconnected, the cross section of the first sub-barrel cavity 13 is a polygon that matches the outer circumference of the second nut 14, the second nut 14 is located in the first sub-barrel cavity 13, the cross section of the second sub-barrel cavity 16 is circular, the box cover 12 is cylindrical that matches the second sub-barrel cavity 16, the box cover 12 is inserted in the second sub-barrel cavity 16, and the end of the box body 11 close to the first sub-barrel cavity 13 (i.e. Figure 1 , 4 -6) is fixedly arranged at the other end (i.e. Figure 1 , 6 , right end as shown in 8-10), the cylindrical cavity of the box body 11 is arranged along the direction from one end to the other end of the buckle body 4, that is, the cylindrical cavity is arranged along the horizontal direction from left to right.

[0041] The first sub-cylinder cavity 13 and the second sub-cylinder cavity 16 are coaxially arranged. In the present embodiment, the outer peripheral surface of the second nut 14 is hexagonal, and correspondingly, the cross-section of the first sub-cylinder cavity 13 is also hexagonal. After the second nut 14 is placed in the first sub-cylinder cavity 13, the axis of the second nut 14 coincides with the axis of the first sub-cylinder cavity 13, that is, the two are coaxially arranged. In this way, the second nut 14 is restricted by the cylinder wall of the first sub-cylinder cavity 13 and cannot rotate.

[0042] like Figure 6As shown, the present invention uses a self-detachable shackle realized by an electric motor, wherein the end surface of the box cover 12 located in the second sub-cylinder cavity 16 is provided with a receiving groove 15 for accommodating the end of the threaded portion 7 away from the polished rod portion 6. When the shackle is in a locked state, the end of the threaded portion 7 away from the polished rod portion 6 may completely pass through the second nut 14, so the receiving groove 15 is provided on the end surface of the box cover 12 located in the second sub-cylinder cavity 16 to accommodate the end of the threaded portion 7 away from the polished rod portion 6.

[0043] like Figure 6 As shown, the self-detachable shackle of the present invention is realized by using an electric motor, wherein the length of the first sub-cylindrical cavity 13 is greater than the thickness of the second nut 14. In this embodiment, the length of the first sub-cylindrical cavity 13 is greater than the thickness of the second nut 14 by a distance of one pitch (the pitch refers to the pitch of the second nut 14), that is, the second nut 14 has a movable space in the horizontal direction along the left and right (the second nut 14 can be against the right end of the shackle body 4 when moving to the left, and can be against the box cover 12 when moving to the right, so the movable space is the first sub-cylindrical cavity 13 between the right end of the shackle body 4 and the box cover 12), so that when the end of the locking rod 5 just contacts the second nut 14 and has not been screwed in, an adjustment space can be provided between the locking rod 5 and the second nut 14 so that the locking rod 5 can be screwed into the second nut 14.

[0044] like Figure 2 , 6 As shown, the present invention uses a motor to realize a self-detachable shackle, wherein two support rods 10 are fixedly arranged on the first nut 9, the two support rods 10 are respectively located on opposite sides of the first nut 9, and the two support rods 10 are respectively fixedly connected to the two second support plates 2. In this way, the first nut 9 is fixedly arranged between the two second support plates 2 through the two support rods 10.

[0045] In order to realize automatic control, a control unit can be provided to connect the motor 3 to the control unit via a cable. The control unit controls the forward and reverse rotation of the motor 3. When the motor 3 rotates forward, the locking rod 5 is driven to rotate forward. Conversely, when the motor 3 rotates reversely, the locking rod 5 is driven to rotate reversely.

[0046] The present invention first welds the first support plate 1 and the second support plate 2 as well as the box body 11 of the nut box 8 to the shackle body 4, then installs the second nut 14 into the box body 11, and then fixes the box cover 12 to the box body 11 to complete the constraint of the second nut 14, then assembles the locking rod 5 and the motor 3 and installs them between the two second support plates 2, then fixes the first nut 9 between the two second support plates 2, and finally connects the control unit to the motor 3 via a cable, thereby completing the pre-assembly of the shackle.

[0047] The beneficial effects of the present invention are as follows: the shackle has a simple structure and low cost, and can achieve self-disassembly after high-altitude lifting equipment, avoiding the danger of manual operation; at the same time, the shackle does not cause structural damage to major load-bearing parts such as the shackle body 4, the shackle bolt nut (i.e., the locking rod 5 and the second nut 14), thereby ensuring the safety of lifting heavy equipment.
