Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel construction equipment, in particular to a splitting propulsion mechanism and a drilling and splitting trolley comprising the same. BACKGROUND

[0002] With the rapid development of high-speed railway and highway traffic construction, it will greatly promote the development of tunnel mechanical excavation construction equipment. The traditional tunnel construction often uses the drill and blast method for excavation. However, due to the limitations of vibration, noise, and explosive control, and the high hardness of surrounding rock, the difficulty of blast excavation is obviously increased, which limits the drill and blast method in special geological conditions and specific working conditions. As a supplement to the drill and blast method or an effective alternative to hard rock tunnel excavation in short-length tunnels, the drill and split method is a safe, stable, efficient, and reliable static pressure excavation method. However, in current splitting construction, manual handheld splitting machines are used to split rocks. The splitting machine is inserted into the splitting hole manually, which has the problem of low work efficiency. At the same time, for the on-board splitting machine, the cross shaft structure of the splitting machine is designed to be self-provided by the purchased splitting machine, and most of them only adapt to vertical downward splitting. This structural defect is that the splitting machine can be arbitrarily swung and cannot be kept in a horizontal position with the propulsion beam. For the hole splitting of the working face, the splitting machine cannot be inserted vertically to the hole, and the splitting head of the splitting machine can only be freely downward, which is easy to operate improperly and cause damage to the splitting head.

[0003] In view of the above, there is an urgent need for a splitting propulsion mechanism and a drilling and splitting trolley comprising the same to solve the problems in the prior art. SUMMARY
