[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0034] Refer to the drawings of the utility model Figures 1 to 5 According to the double-arm crawler-type water mill drilling machine in the embodiments of the utility model, the double-arm crawler-type water mill drilling machine comprises:

[0035] The mobile carrier 1 is provided with a crawler chassis, which has sufficient power and better passability and can adapt to complex working environments.

[0036] The lifting mechanism 2 is fixed to one end of the mobile carrier 1, and the lifting mechanism 2 has a lifting end 21. In order to have a larger lifting range, a multi-stage lifting mechanism can be used to expand the working area range.

[0037] The rotating arm 3 is arranged in two groups and horizontally spaced apart on the lifting end 21, and the guide rail frame 4 is fixed to the rotating arm 3. The guide rail frame 4 rotates about the rotating arm 3 as a fixed shaft. The drilling mechanism on the double-arm mode can change the path, and the working area range is large and the precision is high. The guide rail frame also increases the hole diameter working range of the drilling mechanism.

[0038] The drilling mechanism 5 is slidably connected to the guide rail frame 4, and the drilling direction of the drilling mechanism 5 is parallel to the two groups of rotating arms 3.

[0039] In order to have better platform stability, a plurality of lifting support feet 6 are fixedly connected around the crawler chassis. When in use, the mobile carrier is supported, and when not in use, the lifting support feet are retracted.

[0040] In other embodiments, the lifting end 21 of the lifting mechanism 2 is fixed with a rotating arm base 7, the rotating arm 3 is rotatably connected to the rotating arm base 7, and the rotating arm base 7 is fixed with a power drive part 71 for rotating the rotating arm 3. The power drive part 71 can be a motor, and the motor rotates the rotating arm through a worm and gear mode.

[0041] In order to improve the stability of the distal double arms, the two rotating arms 3 are axially positioned and connected with a constraint sleeve 8, which can be close to the distal position of the rotating arm, and the constraint sleeve 8 is rotationally connected with the corresponding side rotating arm 3. The constraint sleeve does not affect the rotation of the rotating arm. In a specific embodiment, the rotating arm is a rod arm.

[0042] In order to improve the stability during drilling, the constraint sleeve 8 is connected with a telescopic cylinder 9, and the telescopic end of the telescopic cylinder 9 is fixedly connected with a thimble 10. The end of the rotating arm 3 is provided with a sliding groove for guiding the sliding of the thimble 10. It should be noted that the telescopic cylinder can be one or two, and the thimble is preferably two, so as to cooperate with the two rotating arms.

[0043] Specifically, the drilling mechanism 5 includes a sliding seat 51, a motor 52, a speed reducer 53, and a drill cylinder 54. The sliding seat 51 is slidingly connected to the guide rail frame 4. The motor 52 and the speed reducer 53 are fixed to the sliding seat 51, and the motor is drivingly connected to the drill cylinder 54 through the speed reducer. The end of the drill cylinder 54 is not water-sealed, which is convenient to use. The drill cylinder is arranged in parallel with the rotating arm 3 and has a spacing distance therebetween, which can be considered as the drilling radius of the hole.

[0044] In other embodiments, the end of the guide rail frame 4 is fixedly connected with a telescopic power cylinder for moving the sliding seat 51, so as to facilitate the drilling and retraction of the drill cylinder. The rotation of the drill cylinder is controlled by the motor.

[0045] In another specific embodiment, the mobile carrier 1 is fixedly provided with an operation table 11, which controls the working state of the telescopic power cylinder, the motor, the electric power driving part, the lifting support foot, and the lifting mechanism. The operation table is integrated and controlled, which is convenient to operate.
