Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] figure 1 A four-arm rock drilling jumbo according to an embodiment of the present invention is schematically shown. According to the four-arm rock drilling jumbo of the present invention, it can be extended and contracted, and can be extended to increase the working space during work, and can be contracted to reduce the space after the work is completed, so as to facilitate movement.

[0034] Such as figure 1 and figure 2 As shown, the four-arm rock drilling jumbo described in this embodiment includes a chassis assembly 1 . The chassis assembly 1 is configured to be able to support other components and to be able to walk, and the chassis assembly 1 drives other components to move, run or stop. The four-arm rock drilling jumbo also includes four groups of booms 2, and the booms 2 are all arranged at the rear of the chassis assembly 1. Wherein, the boom 2 is prov...

Abstract

The invention relates to a four-arm rock drilling trolley, and belongs to the field of tunnel construction. The four-arm rock drilling trolley comprises a chassis assembly and four groups arm frames,the chassis assembly is constructed to be capable of supporting other assemblies and walking; and rock drilling machines are arranged on the arm frames, the arm frames are constructed to be capable ofdriving the rock drilling machines to complete lifting, expanding and shrinking and deflecting, and the rock drilling machines are pushed to drill rock. The four-arm rock drilling trolley can work atthe same time through four arms, the working efficiency is improved, only one rock drilling trolley is required, and the cost is saved.

Description

technical field [0001] The invention relates to a four-arm rock drilling jumbo, which belongs to the field of tunnel construction. Background technique [0002] With the development of tunnel excavation technology, large-section tunnels have appeared one after another, and the field of tunnel construction is gradually developing towards mechanization, automation, and computerization. At present, the method of blast hole drilling of super large cross-section tunnel is generally realized by the following two methods. First, drill holes by building a bench. However, this method is not safe, and requires a large number of construction workers, and the work efficiency is low; second, two two-arm or three-arm rock drilling rigs are used simultaneously Drilling increases equipment cost and labor cost. Contents of the invention [0003] In view of the above problems, the present invention proposes a four-arm rock drilling jumbo, which can work simultaneously through four arms, i...
