[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0024] like Figs. 1-4 As shown, this embodiment discloses a railway-specific long spiral drilling rig, which includes a long spiral drilling rig, a railway track car 6 at the lower end of the long spiral drilling rig, railway rails 7 symmetrically arranged at the lower end of the railway track car 6, and a railway foundation 9 at the lower end of the railway rails 7. The long spiral drilling rig includes a main unit 1 that provides kinetic energy for various movements of the equipment. A movable connecting arm 5 is arranged at the front end of the main unit 1. A sliding mast 4 is slidably arranged on the movable connecting arm 5. A ground-supporting cylinder 8 is arranged at the lower end of the sliding mast 4 in contact with the ground. A long spiral power head 2 is suspended on the sliding mast 4. A long spiral drill rod 3 is arranged at the lower end of the long spiral power head 2.

[0025] In this embodiment, the front end of the host 1 is also provided with a push cylinder. The push cylinder moves the sliding mast 4 across the area through the sliding action of the movable connecting arm 5. At the same time, the sliding mast 4 suspends the rotary drilling long spiral power head 2 and the long spiral drill rod 3 to meet the requirements of cross-area rotary drilling operation.

[0026] In this embodiment, the sliding mast 4 is divided into a long mast and a short mast. The short mast is equipped with mast bearings on its side. The long mast and the short mast slide against each other. The long mast and the short mast slide against each other and are guided and fixed by the mast bearings. This is beneficial for adapting to construction on different ground levels and can also better stabilize the operation of the sliding mast 4. At the same time, the bottom of the sliding mast 4 is equipped with a ground support cylinder 8 to strengthen the stability of the sliding mast 4. This can effectively solve the limitations of special construction sites and enable construction without differentiation even on sites with height differences. This not only improves construction efficiency but also saves costs. Example

[0027] like Figs. 1-6As shown, the embodiment discloses a long spiral drilling machine for railway, which comprises a long spiral drilling machine, a railway track car 6 arranged at the lower end of the long spiral drilling machine, railway rails 7 arranged symmetrically at the lower end of the railway track car 6, and a railway foundation 9 arranged at the lower end of the railway rails 7. The long spiral drilling machine comprises a main machine 1 for providing kinetic energy for various movements of the equipment, a movable connecting arm 5 arranged at the front end of the main machine 1, a sliding mast 4 arranged slidably on the movable connecting arm 5, a ground supporting oil cylinder 8 arranged at the lower end of the sliding mast 4 and abutting against the ground, a long spiral power head 2 suspended on the sliding mast 4, and a long spiral drill rod 3 arranged at the lower end of the long spiral power head 2.

[0028] In the embodiment, the long spiral drilling machine for railway is connected with the railway track car 6, and the railway track car 6 can move on the railway foundation 9. Thus, when it is necessary to change the construction position, the railway track car 6 can be moved. If a train comes, the equipment occupies the road for construction, and the railway track car 6 can be operated to the side to not interfere with the road. When the equipment needs to be erected, the equipment is rotated by 90 degrees, the equipment is rotated to one side of the drill rod construction, and then the mast is erected until the sliding mast is completely erected by 90 degrees.

[0029] In the embodiment, the long spiral drilling machine is arranged on the railway track car 6, and the railway track car 6 can move on the railway foundation 9. The railway foundation 9 is laid on the railway rails 7, which is beneficial to the connection of the long spiral drilling machine and the railway track car 6, does not need to walk on the track, and eliminates the rolling of the track on the railway foundation 9. The combination with the railway track car 6 ensures the convenience of moving and the rapidity of withdrawing of the working site. Meanwhile, the long spiral drilling machine adopts a multifunctional long spiral power head. The power head can rotate up and down under the condition of rotating the drill rod horizontally, so that the long spiral drill rod can obtain a greater pressure from below to save more time for hole forming.

[0030] Furthermore, the movable connecting arm 5 is retracted to the shortest position to be a working state. The movable connecting arm 5 can be moved back and forth to stretch and retract, so that the long spiral operation at different positions can be performed. When the movable connecting arm 5 is completely stretched out, the ground supporting oil cylinder 8 can be stretched out to support the ground during the construction operation, so that the equipment is more stable.

[0031] Meanwhile, the sliding mast 4 can slide up and down, so that the long spiral power head 2 and the long spiral drill rod 3 slide up and down, and the equipment can be constructed at different ground levels. When the sliding mast 4 does not move during the construction process, the long spiral drill rod 3 can obtain a greater pressure from below through the up and down rotating function of the long spiral power head 2. The long spiral power head 2 can also rotate horizontally, so that the long spiral drill rod 3 rotates while moving downward to achieve the effect of hole forming.

[0032] The basic principle and main features of the present application and the advantages of the present application are shown and described above, and it is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application; therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be considered as limiting the claims.

[0033] In addition, it should be understood that, although the present application is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
