Description

Steel coil clamp and travelling crane equipment Technical Field The utility model belongs to the technical field of driving equipment, and particularly relates to a steel coil clamp and driving equipment. Background When the existing steel coil clamp is used for lifting steel coils, two clamp claws of the clamp firstly extend into a steel coil center hole from two sides of the steel coil respectively, then the clamp claws are driven to ascend to enable the clamp claws to move upwards to contact with the upper edge of the steel coil center hole, and then the steel coil clamp is lifted through travelling crane, so that the steel coil is lifted. Then, in the actual use process, when the clamp claws of the clamp extend into the center hole of the steel coil, the two clamp arms of the clamp the two sides of the steel coil, and at the moment, the clamp is driven to rise, the clamp arms of the clamp scratch the two sides of the steel coil, so that the phenomenon of steel curling loss is caused, and the quality of the steel coil is further affected. Disclosure of Invention In view of the above-mentioned drawbacks of the prior art, the present utility model is directed to a steel coil clamp and a travelling crane device, which are used for solving the problem that the steel coil clamp in the prior art is easy to scratch the steel coil. To achieve the above and other related objects, an aspect of the present utility model provides a steel coil clamp, including a clamp body, the clamp body includes two clamp arms, and jaws are disposed at bottoms of the two clamp arms, wherein the clamp arms include an arm body, a movable lining plate is disposed on an inner side of the arm body, the movable lining plate protrudes from an inner side of the arm body, a top of the movable lining plate is connected with the arm body through a first spring, and a avoidance groove with a set depth is disposed between the jaws and the arm body. Further, the movable lining plate can be compressed into the arm body, a first trigger sensor is arranged in the arm body, a set distance is reserved between the first trigger sensor and the movable lining plate, and when the movable lining plate is compressed into the arm body, the movable lining plate can trigger the first trigger sensor to send out a clamping signal. Further, a hinge plate is hinged in the arm body, the first end of the hinge plate is connected with the movable lining plate, the second end of the hinge plate is connected with a second spring, the first end of the hinge plate is lower than the second end of the hinge plate, the first end of the second spring is connected with the second end of the hinge plate, and the second end of the second spring extends vertically downwards and is connected with the arm body. Further, the movable lining plate comprises a connecting plate and a clamping surface base plate connected with the connecting plate, wherein the connecting plate is positioned in the arm body, the clamping surface basically protrudes out of the arm body, and the top of the connecting plate is connected with the arm body through the first spring. Further, the surface of the movable lining plate is provided with a lug, and the lug protrudes out of the surface of the movable lining plate by 50mm. Further, a second trigger sensor is arranged on the clamp claw, the distance between the second trigger sensor and the front end of the clamp claw is 70 mm-100 mm, and the front end of the clamp claw is one end far away from the arm body. Further, the length of the jaws is 250mm. Further, the set depth of the avoidance groove is 300mm. As described above, the steel coil clamp has the beneficial effects that after a steel coil is clamped by the left clamp arm and the right clamp arm of the steel coil clamp, the left clamp arm and the right clamp arm of the steel coil clamp drive the steel coil clamp to ascend so that the clamp claw at the bottom of the clamp arm is in contact with the upper edge of the center hole of the steel coil (namely, in the process of hooking the steel coil by the clamp claw), as the top of the movable lining plate at the inner side of the arm body is connected with the arm body through the first spring, when the steel coil clamp is driven to ascend, namely, the two clamp arms are continuously ascended, the first spring is stretched by static friction force generated by clamping the steel coil by the movable lining plate along with the continuous ascent of the clamp arm, and the movable lining plate and the steel coil are kept motionless (the avoidance groove between the clamp claw and the arm body can ensure that the movable lining plate is not interfered by the bottom of the clamp claw when the arm body and the clamp claw ascend relatively, thereby the scratch on the movable lining plate is avoided, and the steel coil quality can be effectively ensured. The utility model further provides driving equipment which comprises the steel coil clamp. The beneficial
