Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] It should be clear that the orientation used in the present invention is based on the use status of the rotary drilling rig. Specifically, in figure 1 The views shown are "front" on the left and "rear" on the right.

[0031] figure 1 Shown is a structural schematic diagram of a chassis platform of a rotary drilling rig according to an embodiment of the present invention. The chassis platform of the rotary drilling rig in this embodiment at least includes a platform base 1, a main winch 2, a rotary reducer 3 and an engine 4, and the structure of each part can refer to existing and improved technologies.

[0032] The aforementioned main winch 2 , engine 4 and rotary reducer 3 are arrange...

Abstract

The invention provides a rotary drilling rig and a chassis platform thereof. The chassis platform at least comprises a platform substrate, a main windlass, a rotary speed reducer and an engine. The engine and the rotary speed reducer are arranged on the platform substrate. Only the main windlass is arranged on the platform substrate. The rotary speed reducer is arranged in front of the main windlass. The engine is arranged behind the main windlass. According to the structure configuration manner of the rotary drilling rig, the working load of a mast cylinder can be reduced and furthermore a requirement for the rigidity of the platform is reduced.

Description

technical field [0001] The present invention mainly relates to the field of engineering machinery, in particular to a rotary drilling rig chassis platform and a rotary drilling rig provided with the chassis platform. Background technique [0002] In the prior art, there are two main types of chassis platform layouts for rotary drilling rigs: horizontal engine installation and vertical engine installation. The domestic layout is mainly horizontal, while the foreign layout is mainly vertical (Bao'e, etc.). [0003] The first type of horizontal arrangement is a typical excavator layout. The main valve is placed in the middle of the platform, and the space is small. For the rotary drilling rig, the pipe routing is complicated, maintenance is difficult, and it affects the appearance; the second type of horizontal arrangement , represented by XCMG's self-made chassis, the layout level has been improved and relative specialization has been achieved, but there is still a certain lac...
