Mobile support device

Abstract

The invention discloses a mobile support device. The mobile support device comprises a traveling frame and at least two groups of longitudinal traveling wheel sets arranged on the traveling frame, wherein, the longitudinal traveling wheel sets comprise reverse guide wheels and hanging roller wheels which are connected together through a transmission mechanism, and the reverse guide wheels are connected with a motor; and support pillar feet needed for forming stable support are arranged under the traveling frame. By utilizing the mobile support device, self-acting movement of a trestle can be realized so as to better adapt to various working conditions, and preliminary works for trestle traveling such as excavation face leveling, steel rail pavement and the like as well as applications of auxiliary equipment in the case of traveling are reduced, thus the device has the advantages of good safety performance and high construction efficiency so as to further shorten construction period.

Description

mobile support device technical field The invention relates to engineering operation and transportation equipment, in particular to a mobile supporting device, which can be used for walking on trestle bridges. Background technique With the development of my country's social economy, the pace of national modernization is accelerating, and highways and railways are key projects in my country's transportation construction. With the continuous increase of road and railway construction, tunnel projects also increase, and trestle bridges are the main equipment to solve the interference problems of face excavation, transportation and inverted arch construction in tunnel projects. The traditional simple trestle has no moving device, and it is very inconvenient to use during construction, requiring a large number of personnel and equipment to cooperate with its movement, and it takes a lot of time. Although the existing mobile trestle has increased the mobile device, it is very s...

AI Technical Summary

Problems solved by technology

It requires relatively flat ground for initial support, erection of temporary supports, laying of sleepers and rails, and forklift traction. This kind of mobile trestle moves slowly and requires a lot of labor and mechanical equipment. It takes a long time to operate and cannot fully cooperate with the tunnel. The construction period of blasting excavation increases the construction period, and there are certain safety hazards when moving
