Description

Double-hook intelligent portal crane Technical Field The utility model belongs to the technical field of cranes, and particularly relates to a double-hook intelligent portal crane. Background The two groups of lifting hooks of the double-hook intelligent portal crane are fixed in installation positions, when weights with different lengths are lifted, the distance between the two groups of lifting hooks can be adjusted according to requirements, so that the crane is inconvenient to lift the weights with different lengths, and the adjustability and the applicability of the device are greatly reduced. For example, the chinese patent application with publication number CN115465790a discloses a double-hook intelligent portal crane, but two hooks of the double-hook intelligent portal crane cannot be lifted independently, so that the use requirement of independent lifting is difficult to meet. In the prior art, the Chinese patent with the bulletin number of CN118877730B discloses a double-hook intelligent portal crane, wherein two lifting hooks can independently lift, but two lifting components cannot independently move on a cross beam, so that the use requirement of independent lifting is difficult to meet. Therefore, a double-hook intelligent portal crane which can run synchronously in parallel and independently and meet different hoisting requirements is required to be designed to solve the technical problems faced at present. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides the double-hook intelligent portal crane which not only can synchronously run in parallel, but also can independently run respectively, thereby meeting different hoisting requirements. The double-hook intelligent portal crane comprises a cross beam, wherein a first trolley and a second trolley are arranged on the cross beam, connecting bolts and interval adjusting mechanisms are arranged on two sides of the first trolley, the interval adjusting mechanisms drive the connecting bolts to move along the moving direction of the first trolley, holding clamp locking mechanisms are arranged on two sides of the second trolley and used for clamping or releasing the connecting bolts, the holding clamp locking mechanisms are provided with retaining tables fixedly arranged on the outer side of the second trolley, a support plate is fixedly arranged on one side, away from the second trolley, of each retaining table, two holding clamp blocks are connected onto each support plate, clamping grooves matched with the connecting bolts are formed in one side, close to each holding clamp block, of each support plate, and driving assemblies for driving the two holding clamp blocks to be close to or far away from each other are arranged on each support plate. Further, two parallel connecting rods are hinged to one side, close to the support plate, of the clamping block, one end, away from the clamping block, of each connecting rod is hinged to the support plate, the driving assembly is provided with a driving block, a driving rod is hinged to the driving block, one end, away from the driving block, of each driving rod is hinged to the connecting rod, and a hydraulic cylinder for driving the driving block to reciprocate is arranged on the support plate.
