Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as Figure 1-4 The shown double-deck rotary chassis for a drilling rig comprises a lower frame 1, a central frame 2 and an upper frame 3 stacked sequentially from bottom to top, and the lower frame 1, central frame 2 and upper frame The vehicle frame 3 shares the same central rotating shaft 4, and the three can rotate around the central rotating shaft 4 in pairs. The central rotary shaft 4 is welded and fixed in the middle part of the lower frame 1, and the two ends of the lower frame 1 are provided with traveling mechanism installation parts, and running mechanisms such as crawler belts are installed in the described traveling mechanism installation parts. The lower frame 1 is provided with an oil cylinder installation cavity 11, and a fixed part is arranged in the oil cylinder installation cavity 11. The lower frame oil cylinder 5 is installed in the oil...

Abstract

The invention relates to a double-layer rotary chassis for a drilling rig, which comprises a lower frame, a central frame and an upper frame stacked in sequence from bottom to top, and the lower frame, the central frame and the upper frame share the same center Two of the three rotary shafts can rotate around the central rotary shaft. The invention can realize the two-stage rotation of the upper frame and improve the flexibility of construction work.

Description

technical field [0001] The invention relates to drilling equipment, in particular to a double-layer rotating chassis for a drilling truck. Background technique [0002] All kinds of drilling rigs are widely used in blast hole drilling operations in metallurgy, railways, mines, building materials, highways and other projects. The current drilling rig chassis is generally a fixed chassis, that is, the rotation of the upper body of the drilling rig must be driven by the movement of the chassis running mechanism. The drilling rig with this structure has special requirements on the parking position when drilling rocks, and the drilling position is limited by the parking position. However, it is difficult to accurately adjust the parking position of the drilling rig, which affects the construction efficiency. Contents of the invention [0003] The object of the present invention is to provide a double-deck rotary chassis for drilling rigs that can be relatively rotated through...
