Description

Trolley travelling mechanism for crane

Technical Field

The utility model relates to the technical field of cranes, in particular to a cart travelling mechanism for a crane.

Background

Along with the rapid development of global economy integration, the economy of each country is rapidly developed. Trade transactions between countries are more frequent and ocean transportation is becoming important. The transportation ship is continuously developed towards large scale, so that higher requirements are put forward on the loading and unloading capacity of the port, and the port is more required to be provided with equipment with high loading and unloading efficiency and stable operation.

Currently, the common equipment in ports is a portal crane, a quay crane, a track crane and the like. These devices are provided with a cart running gear, and a stable cart running gear can provide a safe running environment for the whole device. The cart running structure is mainly connected by the hinge shaft, and the service life of cart running is seriously influenced by no good lubrication environment at the connecting part. Each lubrication point is lubricated manually, so that the labor intensity of workers is increased, the workers are required to spend a long time, and each lubrication point cannot be lubricated uniformly by manual lubrication.

The structure of the cart running is also an important factor affecting the cart running performance. A reasonable structure can reduce stress concentration and material waste and can provide convenient operation. In order to facilitate the replacement of wheels, the cart travelling mechanism is generally provided with a lifting plate at the balance beam, and the lifting plate is generally directly welded at the bottom of the balance beam. The wheel is typically replaced once a few years, so the jacking plates are inactive most of the time. The fixed jacking plate not only increases the weight of the whole machine, but also increases the space occupation rate of the bottom of the whole machine.

The cart running mechanism can stably run without limit. Currently, several cranes are required to work together on one quay. When the crane moves, the two cranes collide with each other when the operator is not careful, the light weight equipment is damaged, and the heavy weight is destroyed. In order to avoid collision of the two devices, a limiting mechanism is arranged on each crane, and when the two devices are close to a certain distance, an operator is reminded to stop moving the devices. At present, a heavy limiting device is arranged on the crane, and if the limiting device fails, accidents cannot be avoided.

One patent with the Chinese patent publication number of CN 204324721U discloses a crane cart travelling mechanism, one patent with the Chinese patent publication number of CN 103342282A discloses a crane cart travelling mechanism, and one patent with the Chinese patent publication number of CN 104590993A discloses a cart travelling mechanism. The cart walking proposed by the three patents comprises main steel structures such as balance beams, trolley frames and the like. However, none of these three patents mention the manner of lubrication at the hinge and the design of the stop device.

Aiming at the problem that the automatic lubrication of the whole travelling crane cannot be realized, the travelling crane travelling mechanism for the crane is provided.
