Problems solved by technology

[0003] Most of the rotary drilling rigs in the prior art are assembled on automobiles or crawler bases, and have the following defects in use: one, when the road inclination angle is too large or when construction is carried out on a railway with railroad tracks, in the prior art The bottom support device of the special railway rotary drilling rig cannot enter the construction site, so it cannot be used during railway construction. Due to the restrictions of the construction site, the use has certain limitations
2. The existing bottom support device for railway special rotary drilling rig is large in size, which easily makes the car exceed the vehicle height limit, and is not convenient for the transportation of the bottom support device for railway special rotary drilling rig

Embodiment 1

[0033] Example 1 A Bottom Support Device for Railway Special Rotary Drilling Rig

[0034] In this embodiment, the expansion and contraction of the telescopic mechanism on the support frame is controlled by the driving mechanism, so that the rotary drilling rig can be stably supported by extending the telescopic arm 2 and telescopic legs during railway line construction, and can be shortened during transportation. , Telescoping legs for easy transport.

[0035] Such as Figure 1 to Figure 2 As shown, this embodiment includes a support frame, a telescoping mechanism and a driving mechanism.

[0036] 1. Support frame

[0037] The support frame is used to support the rotary drilling rig. The support frame is a frame-shaped structure arranged horizontally, and the top surface of the support frame is placed on a horizontal plane. In order to facilitate the movement of the support frame, a moving mechanism is provided below the support frame to move the support frame on the railw...

Embodiment 2

[0048] Embodiment 2 A method of using the bottom support device of a special railway rotary drilling rig

[0049] This embodiment utilizes the bottom supporting device of the railway-specific rotary drilling rig in Embodiment 1, and is used in conjunction with the rotary drilling rig for construction on railway lines. The method of using the bottom supporting device of the railway-specific rotary drilling rig includes the following steps:

[0050] S1. Move the support frame to the working position through the flat car.

[0051] S2. Drive the telescopic arm 2 to extend horizontally to the working position through the hydraulic cylinder, that is, the telescopic arm 2 drives the telescopic legs at both ends of the telescopic arm 2 to move outward relative to the support frame.

[0052] S3. Drive the first telescopic leg 4 to extend downward in a direction perpendicular to the horizontal plane through the hydraulic cylinder, that is, the first telescopic leg 4 drives the second tele...

Abstract

The invention discloses a bottom supporting device for a rotary drilling rig special for a railway and an application method thereof. The bottom supporting device for the rotary drilling rig special for the railway comprises a supporting frame, the supporting frame comprises at least two telescopic mechanisms connected through bottom beams, each group of telescopic mechanisms comprises a telescopic arm and a telescopic leg, the telescopic arms are fixed to the supporting frame and can telescope in the horizontal direction, and the telescopic legs are fixedly connected to the two ends of the telescopic arms. The application method for the bottom supporting device for the rotary drilling rig special for the railway comprises the following steps that S1, the supporting frame is moved to the working position; S2, the telescopic arms telescope to the working position in the horizontal direction; and S3, the telescopic legs extend downwards in the direction perpendicular to the horizontal plane to make contact with the supporting surface. The bottom supporting device and the application method thereof are suitable for railway construction, are convenient to transport, are suitable for being used in the working process of the rotary drilling rig, particularly in the construction process of the rotary drilling rig on a rail track, and are used for stably supporting the rotary drillingrig.

Description

technical field [0001] The invention belongs to the technical field of railway construction, and in particular relates to a bottom support device for a special railway rotary drilling rig and a method for using the same. Background technique [0002] Rotary excavator is also called rotary drilling rig and pile driver. Rotary drilling rig is a comprehensive drilling rig, which can be used in various geological conditions such as frozen soil, and has the characteristics of fast hole forming, less pollution, and strong mobility. The rotary drilling rig can cooperate with the hammer to drill the hard formation and carry out the hole digging operation. If it is matched with the expansion head drill, the hole reaming operation can be carried out at the bottom of the hole. The rotary drilling rig adopts multi-layer retractable drill pipe, which has less auxiliary drilling time, low labor intensity, no need for mud circulation and slag discharge, and saves costs. It is especially ...
