Description

TECHNICAL FIELD

[0001] The present application relates to the field of tunnel engineering construction equipment, in particular to a sliding beam track connecting structure, a rack and a tunneling trolley. BACKGROUND

[0002] The rack or trolley is a common construction equipment in the tunnel construction process, which is used for key processes such as tunnel excavation, stand, anchor rod, and shotcreting. A series of tunnel construction is completed by different types of mechanical arms on the rack. The sliding beam track is provided on the rack to facilitate the movement of the mechanical arm.

[0003] The connecting structure between the common sliding beam track and the rack includes an embedded structure, a spring sheet connection, a bolt-slot-elastic element combination connection, etc. The embedded structure has a groove on the rack, which matches the cross-sectional shape of the sliding beam track. The track is embedded in the groove. Then the side of the embedded part can be fixed transversely by bolts or wedges are driven in to fix the track tightly in the groove, enhance the rigidity of the connection, and ensure the stability of the sliding beam operation. The spring sheet connection structure installs spring sheets between the sliding beam track and the rack. One end of the spring sheet is fixed on the rack, and the other end is connected with the track. This structure can buffer the vibration and impact generated during the operation of the sliding beam to a certain extent, and is suitable for situations with high requirements for equipment operation stability, while allowing a small relative deformation between the track and the rack to a certain extent.

[0004] In the above related technology, the embedded structure has high precision requirements and is difficult to process. Once the track is embedded, it is difficult to adjust, and the wedges or bolts may loosen over time. The spring sheet connection structure has limited bearing capacity of the spring sheet, which may fail due to fatigue over time, and has requirements for installation space and complex structure. The rubber pad connection structure is prone to aging, wear and tear, has low bearing capacity, and its performance may decrease in high temperature or chemical corrosion environment. The bolt-slot-elastic element combination structure is complex, has high cost, and the elastic element and bolt need to be regularly inspected and maintained. Foreign matter may enter the slot and affect the installation accuracy of the track. Practical new type content
