Problems solved by technology

[0002] Existing bridge cranes are used in enterprise workshops. The products and raw materials in the workshop need to be transported to the next workshop or other departments in real time; The beam runs back and forth, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop. In this way, the range of goods that the crane hook can lift is within the plane surrounded by the two ends of the two cart rails in the workshop. When the goods on the edge of this plane need to be hoisted, the hook will be pulled obliquely, and the items farther away from this plane (such as outside the workshop door, outside the span) cannot be hoisted. At this time, they can only be transferred by other transportation equipment. , Usually the car drives into the workshop to lift the goods under the hook. If some cars cannot drive in, a track is laid horizontally between the workshop and the next-door workshop, and the special rail car is driven to the hook to deliver the goods, and some are in the workshop. A special cantilever crane is set up at the door (or workshop aisle) to transfer and dispatch the goods outside the workshop. First, the goods are hoisted into the place where the crane hook of the workshop can reach, and then the goods are hoisted by the crane to the For other stations in the workshop, the existing bridge cranes used in this working condition cannot directly transfer goods with the next-door workshop, and must use other transportation equipment to dispatch operations, which brings considerable inconvenience and wastes manpower and material resources; some grain warehouses The cranes used for hoisting items in industrial explosion-proof workshops require electrical appliances to have explosion-proof functions. Explosion-proof motors and explosion-proof electric hoists are required. The cost is very high, especially for places with small tonnage and low work levels. The use of explosion-proof electric cranes requires a large investment and high maintenance costs. ; There are also workshops that do not provide electricity, and rely on forklifts or manpower to carry objects, which is too labor-intensive

Abstract

The invention discloses a dolly steel rope driven crane with a C-slot cantilever beam and a balance weight. The crane comprises two end beams and two main beams. Two end beams and two main beams forma dual beam crane span structure. A hand-pulled cart operation device is arranged between two end beams. An inverted U shape track is arranged above each main beam. A running dolly is arranged betweentwo tracks. The running dolly is provided with a steel rope driving device and a rotation mechanism. In the rotation mechanism, the lower end of a suspender shaft of the rotation mechanism is connected to a cantilever member. The cantilever beam of the cantilever member is formed by C shape steel channels, and the grooves are downward. A slide cart is arranged in the groove of one end of the cantilever beam, and a balance weight is hung on the other end of the cantilever beam so as to prevent tipping. The slide cart can horizontally reciprocate in the groove of the cantilever beam. A hand-pulled chain hoist is hung under the slide cart and can lift goods. The cantilever beam is arranged under two main beams, can stretch out of a workshop to operate, and is capable of rotating.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a trolley steel rope driven crane with a C-shaped groove cantilever beam and a counterweight. Background technique [0002] Existing bridge cranes are used in enterprise workshops.
