Crane with cross beam provided with locking device

Abstract

The invention relates to the technical field of cranes, in particular to a crane with a cross beam provided with a locking device. The crane comprises the cross beam, the cross beam is provided with aguide rail, a traveling crane is slidably mounted in the guide rail, an electric hoist is fixedly mounted on the traveling crane, the cross beam is provided with a cross groove, a locking plate is fixedly mounted in the cross groove, and a clamping groove is formed in the locking plate; and a side bracket is fixedly mounted on the traveling crane, a driving gear and a driven gear are rotatably mounted in the side bracket, cranks are fixedly mounted on gear shafts of the driving gear and the driven gear, and a first connecting rod and a second connecting rod are rotatably mounted on the cranks. The cross beam is provided with the cross groove with the locking plate, clamps are mounted on the two sides of the traveling crane on the cross beam through the side support, the two clamps move inwards at the same time to be clamped on the locking plate, generated force has a locking effect on the traveling crane, it is guaranteed that a heavy object is safely and stably lifted through the electric hoist, and accidents are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane with a locking device on the beam. Background technique [0002] Crane is an important large-scale transportation tool and one of the necessary machinery for shipping operations and engineering construction. The gantry crane is the most common type of crane. The electric hoist is mainly used as the core lifting component. The electric hoist is assembled on the crane to carry out the transfer and handling of heavy objects, which can fully save manpower and improve efficiency. But now the braking force of the electric hoist of the crane is insufficient, and the driving is prone to shift during use, especially when heavy objects are hoisted on the electric hoist, safety accidents are prone to occur and cause greater losses. In view of Therefore, we propose a crane with a locking device on the beam. Contents of the invention [0003] The object of the present invention is ...
