Description

Technical Field

[0001] The utility model relates to the technical field of clamps for cranes, in particular to a clamp for dynamically clamping aluminum coils without a fixed height. Background Art

[0002] When existing rolling mills produce aluminum coils, they will produce aluminum coils of different diameters according to order requirements. However, when using an overhead crane to clamp the aluminum coils, the traditional practice is: a person manually walks to the side of the aluminum coil, observes and aligns it with the center of the aluminum coil before clamping it. This practice has the following defects: 1. Since some aluminum coils are hot-rolled coils with relatively high temperatures, there are safety hazards for humans working next to them, such as burns, rapid sweating, and sweat flowing to the eyes that affects vision. 2. During use, due to the uneven skills of operators and their lack of concentration, they make mistakes, which often cause the clamp to drop too low, resulting in the top of the clamp hitting the aluminum coil.

[0003] To this end, we designed a clamp that can dynamically clamp the aluminum coil without a fixed height. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a clamp for dynamically clamping an aluminum coil without a fixed height.

[0023] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. to indicate directions or positional relationships, they only correspond to the drawings of the present application, in order to facilitate the description of the present invention; it should be understood that if there are terms such as "end", "side", "end part", "lateral", "lateral", "transverse", "longitudinal", etc. to indicate directions or positional relationships, they only correspond to the length and width of the corresponding parts, that is, "end part" indicates the head and tail areas in the length direction of the corresponding part, and "side part" indicates the head and tail areas in the width direction of the corresponding part; this is for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0024] Embodiment 1, in combination with the attached Figure 1-4 A clamp for dynamically clamping aluminum coils without a fixed height comprises a clamp body 1, and both ends of the clamp body 1 have downwardly extending clamp legs 11; further, the clamp body 1 comprises a crossbeam 13, a movable pulley assembly 14 is provided in the middle of the top surface of the crossbeam 13, and the two sections of the crossbeam 13 are movably connected with the clamp legs 11 along the length direction thereof; a driving device 15 is provided in the middle of the crossbeam 13 for driving the two clamp legs 11 to move synchronously and in opposite directions, so that the two clamp legs 11 can clamp or release the aluminum coil. According to needs, the driving device 15 can be a bidirectional air cylinder, a bidirectional electric cylinder or other equipment.

[0025] According to the needs, in order to increase the smoothness and stability of the movement of the clamping leg 11, the top surfaces of the two sections of the beam 13 are provided with linear slide rails 16, the top of the clamping leg 11 is provided with a frame structure 6 that is movably sleeved on the periphery of the beam 13, and the top surface of the frame structure 6 is provided with a slider 61 that is slidably matched with the linear slide rail 16. According to the needs, two linear slide rails 16 can be provided at intervals along the width direction of the beam 13.

[0026] Furthermore, in order to prevent the clamping leg 11 from moving excessively and causing the slider 61 to slide out of the linear slide rail 16, both sections of the beam 13 are provided with limit grooves 131 along their length direction, and the two ends of the limit groove 131 correspond to the two ends of the linear slide rail 16 in the same direction; the frame structure 6 is provided with a limit matching portion 62 inserted into the limit groove 131.

[0027] The lower ends of the inner sides of the two clamping legs 11 are provided with an insertion rod 12 that can be inserted into the central hole of the aluminum coil; as required, in order to prevent the top of the insertion rod 12 from rigidly contacting the top wall of the central hole of the aluminum coil, a flexible layer 121 is provided on the top of the insertion rod 12. The clamping legs 11 are provided with through grooves at the upper and lower positions of the insertion rod 12, and the detection device 2 is installed in the installation through groove, and the distance between the upper detection device 2 and the bottom surface of the insertion rod 12 is less than the diameter of the central hole of the aluminum coil.

[0028] Furthermore, the frame structure 6 includes an n-type plate 63 and a U-shaped plate 64 fixedly installed on the upper end of the clamp leg 11, and both ends of the open end of the n-type plate 63 are provided with outer bending portions 631, and both ends of the open end of the U-shaped plate 64 are provided with inner bending portions 641 overlapped on the top surface of the corresponding outer bending portion 631, and the inner bending portion 641 is connected to the outer bending portion 631 by bolts.

[0029] In this arrangement, even if the assembly of the inner bending portion 641 and the outer bending portion 631 becomes loose, the inner bending portion 641 can be supported by the outer bending portion 631 to prevent the clamping leg 11 from being unstable, thereby improving practicality.

[0030] In order to prevent the heat emitted by the hot-rolled coils from causing "high temperature" in the detection device 2 when the hot-rolled coils are transported, thereby affecting the service life of the detection device 2, an air duct pipe 3 is connected to the outer port of the installation slot, and a port of the air duct pipe 3 away from the installation slot is correspondingly connected to the air supply port of the fan 4; preferably, the air inlet of the fan 4 is located on the side away from the aluminum coil; in this way, the temperature of the air flow delivered by the fan 4 can be ensured to be low, effectively reducing the stability around the detection device 2.

[0031] As required, the detection device 2 may adopt a sensor, such as a photoelectric sensor.

[0032] Specifically, the detection device 2 is connected to the hoisting component signal of the corresponding crane.

[0033] It should be noted that before unloading the aluminum coil, the position of the aluminum coil in the horizontal plane is specific, and it is explained in three-dimensional space, such as: the X-coordinate and Y-coordinate positions of the aluminum coil are fixed, and the heights of the center holes of the aluminum coils are different due to the different diameters of the aluminum coils. Therefore, the crane used can make special settings for the X-coordinate and the Y-coordinate, that is, the fixture can be quickly and accurately moved to the corresponding X-coordinate and Y-coordinate, and only the Z-coordinate needs to be considered.

[0034] When in use, first use a crane to move the clamp to the corresponding X-coordinate and Y-coordinate, then use the crane to lower the clamp. During the descent, first the detection device 2 below detects the aluminum coil, and then the crane's lifting assembly reduces the clamp's descent speed until the detection device 2 above detects the aluminum coil. Then, the crane's lifting assembly can further reduce the clamp's descent speed until the signal detected by the detection device 2 above disappears. At this time, it can be said that the insertion rod 12 has been able to be inserted into the center hole of the aluminum coil, and then the drive device 15 drives the two clamping legs 11 to move relative to each other to complete the operation of clamping the aluminum coil.

[0035] This arrangement can detect through the detection device 2 below that the insertion rod 12 is about to fall to the appropriate position, and by reducing the descending speed of the clamp to ensure safety, the detection device 2 above can detect that the insertion rod 12 has fallen to a position where it can be inserted into the center hole of the aluminum coil, and cooperate with the drive device 15 to realize the function of automatically clamping the aluminum coil, thereby solving the technical problem of the existing technology that requires manual approach to the hot-rolled aluminum coil, which poses a safety hazard.

[0036] This arrangement can also allow the cold air sucked in by the fan 4 to be blown toward the detection device 2, preventing the hot air caused by the hot aluminum coil from diffusing to the vicinity of the detection device 2 and causing the detection device 2 to become "high temperature", thereby ensuring that the detection device 2 can operate normally.

[0037] Embodiment 2, combined with the attached Figure 1-4 , a clamp for dynamically clamping an aluminum coil without a fixed height. Based on the first embodiment, the distance between the two detection devices 2 on the same side is smaller than the diameter of the center hole of the aluminum coil.

[0038] In this arrangement, when both detection devices 2 detect the aluminum coil and then the detected signal disappears again, that is, both detection devices 2 are correspondingly located in the center hole area of ​​the aluminum coil, it can be ensured as much as possible that the insertion rod 12 is coaxial with the center hole of the aluminum coil.

[0039] Furthermore, the distance between the upper detection device 2 and the insertion rod 12 is greater than the distance between the lower detection device 2 and the insertion rod 12. In this arrangement, when both detection devices 2 detect the aluminum coil and then the detected signal disappears again, that is, both detection devices 2 are located in the center hole area of ​​the aluminum coil, the insertion rod 12 can be kept coaxial with the center hole of the aluminum coil as much as possible.

[0040] Embodiment 3, in combination with the attached Figure 3-4, a clamp for dynamically clamping aluminum coils without a fixed height. On the basis of the first embodiment, the air duct pipe 3 is a C-shaped pipe or a U-shaped pipe with an opening in the middle of the outer arc surface or the inner surface, and the two ends of the air duct pipe 3 are respectively connected to the two outer ends of the mounting through groove of the same clamp leg 11. A bracket 5 supporting the air duct pipe 3 is provided at a position corresponding to the middle of the air duct pipe 3 on the outer side of the clamp leg 11, and the bracket 5 is also provided with a fan 4 whose air supply port is connected to the opening.

[0041] The bracket 5 can support the air duct pipe 3 and install the fan 4, thereby improving the stability of the fan 4 and the air duct pipe 3.

[0042] As needed, a temperature sensor connected to the signal of the fan 4 can be provided at the lower end of the clamping leg 11, so that the ambient temperature can be sensed by the temperature sensor to automatically start and stop the fan 4, which is more intelligent than the manual start and stop of the fan 4 in the embodiment.

[0043] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
