A traveling trolley and wheel quick replacement method of a container gantry crane

Abstract

The invention discloses a travel trolley of a container gantry crane and a method for quickly changing wheels. The travel trolley comprises a balance beam. The upper end of the balance beam is used for being connected with a lower transverse beam of a crane gantry assembly, the lower end of the balance beam is connected with a trolley frame, and a travel wheel set and a gear motor with a brake are arranged on the trolley frame. The travel trolley is characterized in that a jack seat which is fittingly connected with a jack is arranged at the front end of the balance beam, jack seats which are fittingly connected with two other jacks are arranged on two sides of the trolley frame, and a triangle is formed by the three jack seats. The jacks can start to be lifted after being arranged in place if the travel wheel set is required to be changed, so that travel wheels can be separated from rail surfaces, bearings can be separated from the trolley frame by the aid of tools, and then the travel wheel set can be changed. The travel trolley and the method have the advantages that designed special jack supports are used as action points of the jacks, the damaged wheels can be directly changed, the time and labor can be saved, and the travel trolley and the method are convenient and speedy.

Description

Technical field [0001] The invention relates to the field of cranes, in particular to a method for quickly replacing a traveling trolley and wheels of a container gantry crane. Background technique [0002] At present, large-tonnage container gantry cranes are more and more widely used, and they have the characteristics of large span, heavy lifting, high lifting height, and high working level. The walking trolley wheels are the load-bearing parts of the whole machine and work frequently all year round. It is easy to cause wheel flange wear and bearing damage. Since the design of the cart traveling trolley does not have relevant supporting protection measures, the entire trolley and even the entire crane will collapse, posing safety hazards. In addition, the current situation of wheel gnawing on the wheel of the cart traveling trolley often occurs, resulting in serious wear of the wheel rim, and the wheel needs to be replaced frequently. When the wheel of a traditional gantry cran...

Problems solved by technology

[0002] At present, large-tonnage container gantry cranes are more and more widely used, and have the characteristics of large span, heavy lifting capacity, high lifting height, and high work level. It is easy to cause wheel rim wear and bearing damage. Since the design of the cart traveling trolley does not have relevant supporting protection measures, the entire trolley and even the entire crane will collapse, posing a safety hazard

In addition, at present, the wheels of the traveling trolleys of the carts occasionally gnaw on the rails, resulting in serious wear of the wheel rims, and the wheels need to be replaced frequently. However, when replacing the wheels of traditional gantry cranes, the entire traveling trolley needs to be disassembled for replacement, which is time-consuming strenuous
