Description

Truss type portal crane for shipbuilding Technical Field The utility model belongs to the technical field of cranes, and particularly relates to a truss type portal crane for shipbuilding. Background The truss type portal crane for shipbuilding is commonly used in a relatively open place, wind is easy to occur, wind force is large, wind-proof cables are detachably mounted on two sides of the supporting leg assembly, when the wind force is large, one ends of the wind-proof cables are mounted on the supporting leg assembly, the other ends of the wind-proof cables are mounted on the ground, the crane is prevented from tipping, a certain time is required for setting the wind-proof cables, the wind-proof cables cannot be mounted immediately when the wind force is large, and the crane still has a tipping risk. In the prior art, chinese patent literature with an authorized bulletin number of CN221836584U discloses a truss type portal crane for shipbuilding, wherein the end part of a sliding rod in a reinforced connecting mechanism is arranged inside a sliding notch of a reinforced slideway in a sliding manner, so that the connection stability between a cart moving mechanism and the ground can be enhanced, the cart moving mechanism is not easy to topple over when a strong wind attacks, the traveling of the cart moving mechanism cannot be interfered, sundries easily enter the sliding notch arranged on one side of the reinforced slideway, the sundries inside the reinforced slideway are not convenient to clean, the movement of a holding disc in an unlocked state is influenced, and the movement stability of the crane is further influenced. Therefore, it is necessary to design a truss type portal crane for shipbuilding, which can automatically clean sundries along with the movement of a crane, avoid the continuous influence on the stable operation of the crane, and simultaneously can strengthen the connection stability between a cart moving mechanism and the ground so as to solve the technical problems faced at present. Disclosure of Invention Aiming at the defects existing in the prior art, the utility model provides the truss type portal crane for the shipbuilding, which can automatically clean sundries along with the movement of the crane, avoid the continuous influence on the stable operation of the crane, and can enhance the connection stability between the cart moving mechanism and the ground. The truss type portal crane for the shipbuilding comprises a crane main body, wherein supporting legs are arranged at two ends of the crane main body, a cart assembly is arranged at the bottom end of each supporting leg, rails matched with the cart assembly are arranged on the ground, a sliding rail assembly parallel to the rails is arranged on the ground, a vertical plate fixedly arranged on the ground is arranged on the sliding rail assembly, a transverse plate is vertically and fixedly arranged on one side of the vertical plate, a sliding rail is fixedly arranged at the bottom of the transverse plate, a support is fixedly arranged on the outer side of the cart assembly, pulleys are connected to the bottoms of the sliding rails in a sliding mode, a locking mechanism used for locking or releasing the cart assembly and the sliding rail assembly is arranged on the support, and cleaning mechanisms are arranged at two ends of the cart assembly.
