Problems solved by technology

This structure has the following problems: 1. Tooling needs to be designed before assembly to ensure that the wheel treads are on the same plane, and it is not adjustable during the assembly process, making assembly difficult; 2. If there are errors in the treads of the four wheels during assembly , then in actual operation, there may be a phenomenon that one of the wheels does not contact the running track; 3. The gap between the wheel and other parts cannot be adjusted according to the actual situation in the actual use process; 4. The contact area of ​​the wheel on the track Unable to adjust after hours

Abstract

The invention discloses an adjustable running wheel set, which comprises a wheel set fixing frame, vehicle wheels in rolling contact with rails and a motor which is arranged on the wheel set fixing frame to drive the vehicle wheels and also comprises a vehicle wheel fixing plate arranged on the outer side of the wheel set fixing frame, wherein the vehicle wheels are in threaded connection with the vehicle wheel fixing plate through a horizontal adjustment device; and the vehicle wheel fixing plate and the wheel set fixing frame above the vehicle wheel fixing plate are provided with a vertical adjustment device. The adjustable running wheel set has the advantages of compact structure, reasonable and reliable layout, simple and convenient assembly, safe and stable running, accurate positioning and long service life of products, can adjust the horizontal and vertical states of the vehicle wheels according to the actual situation, ensure the effective contact and enough contact area of the vehicle wheels and the rails and meet the using requirements of multiple heavy weights and running rails.

Description

technical field [0001] The invention relates to a lifting machinery auxiliary equipment, in particular to an adjustable running wheel set for a segment crane. Background technique [0002] With the rapid development of modern society and the improvement of people's living standards, people's living scope is gradually expanding, the pace of life is constantly accelerating, and the requirements for public transportation are getting higher and higher. At present, the state vigorously advocates and encourages the development of underground rail transit in various places, especially in some large and medium-sized cities with developed economies to actively build subway traffic. Underground tunnels are the main form of subway transportation, and segment cranes are an indispensable means of transportation in the construction of underground tunnels. The traditional segment crane runs the wheel set, and the travel motor is used to directly drive the wheel or the wheel and the suppor...
