[0032] By adjusting the unfolding angle of rotating beam 4, the angle between drill bit 62 and the side wall of bridge pile foundation can be flexibly changed, so as to accurately adjust the direction of drilling to adapt to different construction requirements.

[0033] Through the measuring assembly 7, the operator can directly observe the depth of drill bit 62, which improves the accuracy of construction.

[0034] It should be noted that the screw lifter 5 mentioned in this paper adopts the existing technology, and its structure and principle are consistent with the screw lifter in the bridge pile foundation lateral position puncher based on the safety performance of the bridge disclosed in the utility model patent with publication number CN207513562U, which is matched with the guide rail arm 41 to move the puncher machine body 6.

[0036] Specifically, the relative position between the C-shaped beam 11 and the movable beam 12 can be adjusted according to the height of the punching position, and then fixed by the limiting pin rod 13, so as to realize the adjustment of the overall height of the adjustable telescopic column 1.

[0037] Further, the two side walls of the C-shaped beam 11 are equally spaced and penetrated to form a plurality of fixing holes 111 for installing the limiting pin rod 13, and the lower end of the two side walls of the movable beam 12 is penetrated to form a limiting hole 121 for installing the limiting pin rod 13, the limiting pin rod 13 penetrates the fixing hole 111 and the limiting hole 121, and the two ends of the limiting pin rod 13 are threadedly sleeved with a fixing nut 131.

[0038] Specifically, when it is necessary to adjust the overall height of the adjustable telescopic column 1, only the fixing nuts 131 at both ends of the limiting pin rod 13 are unscrewed, and then the limiting pin rod 13 is removed, at this time, the C-shaped beam 11 and the movable beam 12 are in a relative movable state. Then, according to the position of the punching, the height of the movable beam 12 extending out of the C-shaped beam 11 is adjusted, after the adjustment is completed, the limiting pin rod 13 is inserted into the corresponding fixing hole 111 and limiting hole 121, and the fixing nut 131 is sleeved at both ends of the limiting pin rod 13.

[0040] Specifically, when the base 2 is placed on the ground for use, the extension plate 23 can be moved out of the guide groove 22 to a certain length, and by the extension of the extension plate 23, the supporting area of the base 2 is increased, avoiding the risk of the base 2 falling, thereby ensuring the safety and stability of the equipment during use. When additional support is not needed, the extension plate 23 can also be conveniently slid back into the guide groove 22, reducing the occupied space and facilitating storage and transportation.

[0041] Further, the rotating beam 4 further comprises a C-shaped sliding plate two 42 and a fixed lug 43, the C-shaped sliding plate two 42 is fixedly connected to the lower surface of the guide rail arm 41, the fixed lug 43 is fixedly connected to the right side of the guide rail arm 41 and the C-shaped sliding plate two 42, the center of the fixed lug 43 is fixedly connected with a shaft rod 44, and the rear end of the shaft rod 44 is threadedly sleeved with a locking nut 442 for fixing the relative position of the shaft rod 44 and the support lug 3.

[0042] Specifically, when the deployment angle of the rotating beam 4 needs to be adjusted, the locking nut 442 is simply unscrewed, and then the rotating beam 4 is deployed, the rotating beam 4 is rotated with the shaft rod 44 and the support lug 3, and after the deployment angle of the rotating beam 4 is adjusted, the locking nut 442 is tightened to abut against one side of the support lug 3, so that the relative position between the shaft rod 44 and the support lug 3 is stable, and the rotating beam 4 is prevented from moving or loosening unnecessarily during work.

[0043] Further, the front rotating hole of the support lug 3 is provided with an angle line 31, and the front end of the shaft rod 44 is fixedly connected with a pointer 441 for reading the angle line 31.

[0044] Specifically, when the deployment angle of the rotating beam 4 needs to be adjusted, the shaft rod 44 drives the pointer 441 to rotate. With the rotation of the shaft rod 44, the pointer 441 slides on the angle line 31 and points to the scale position corresponding to the current rotation angle. At this time, the scale of the angle line 31 pointed to by the pointer 441 can clearly show the current deployment angle of the rotating beam 4, helping the operator to accurately control the angle adjustment of the rotating beam 4, so that the angle adjustment of the rotating beam 4 is more intuitive and convenient.

[0045] Further, the measuring assembly 7 comprises an inner hollow fixing seat 71 and a sliding rod 72. The left side of the fixing seat 71 is open, the upper surface of the fixing seat 71 is provided with a movable groove 711, the upper surface of the fixing seat 71 and the front side of the movable groove 711 are provided with a scale line 712, the left side of the inside of the fixing seat 71 is slidingly connected with the sliding rod 72, the right end of the sliding rod 72 is fixedly connected with a spring 73, the right end of the spring 73 is fixedly connected to the right side wall inside the fixing seat 71, the upper surface of the right side of the sliding rod 72 is fixedly connected with a fixed block 721 for reading the scale line 712, the outside of the fixing seat 71 is slidingly connected with a limiting ring 76 for limiting the sliding of the fixed block 721, the limiting ring 76 and the fixing seat 71 are fixedly connected by bolts, the fixed block 721 is located at the leftmost side of the movable groove 711 and the left side of the sliding rod 72 is located on the same vertical line as the left side of the drill bit 62 before punching, the left side of the lower surface of the fixing seat 71 is fixedly connected with a connecting rod 74, the lower end of the connecting rod 74 is fixedly connected with a fixed ring buckle 75, and the fixed ring buckle 75 is detachably sleeved on the left end outside of the punch body 6.

[0046] Specifically, the relative position of the limiting ring 76 outside the fixed seat 71 can be adjusted according to the preset punching depth, and fixed by a bolt (when adjusting the position of the limiting ring 76, the scale line 712 can be used for positioning). During the punching process, the end of the sliding rod 72 away from the fixed seat 71 always elastically abuts against the side wall of the bridge pile foundation under the elastic force of the spring 73. As the drill bit 62 gradually drills into the side wall of the bridge pile foundation, the sliding rod 72 will slide towards the fixed seat 71, and drive the fixed block 721 to slide in the movable groove 711. As the punching depth increases, the fixed block 721 will gradually move to one side of the limiting ring 76 until the fixed block 721 contacts the limiting ring 76, which means that the punching depth has reached the preset requirement, and the operator can determine whether the punching has been completed according to this position. During the punching operation, the operator can also observe the position of the fixed block 721 on the scale line 712 to intuitively understand the current punching progress.

[0047] Further, the positioning assembly 8 comprises a square plate 81 and four groups of inserting rods 82, the square plate 81 is fixedly connected to the left side of the guide rail arm 41 and the C-shaped sliding plate two 42, four sides of the square plate 81 are provided with inserting grooves 811 for inserting the inserting rods 82, the ends of the four groups of inserting rods 82 away from the inserting grooves 811 are fixedly connected with positioning plates 83, and the surface left side of the base 2 is provided with a notch 24 for accommodating the square plate 81.

[0048] Specifically, when the base 2 needs to be placed on the ground for use, considering that the ground may be inclined, the device needs to be positioned before installation. Specifically, the four groups of inserting rods 82 are inserted into the corresponding inserting grooves 811, the position of the base 2 is adjusted to ensure that the four groups of positioning plates 83 are in close contact with the side wall of the bridge pile foundation, and at this time, the position of the drill bit 62 is in a relative vertical state with the side wall of the bridge pile foundation. When one of the left and right groups of positioning plates 83 is not in close contact with the side wall of the bridge pile foundation, it indicates that the device is placed in a left-right inclined state. When one of the upper and lower groups of positioning plates 83 is not in close contact with the side wall of the bridge pile foundation, it indicates that the ground is inclined front-back, at this time, only the unfolding angle of the rotating beam 4 needs to be adjusted so that the rotating beam 4 is in a vertical state with the side wall of the bridge pile foundation, thereby ensuring the positioning accuracy of the entire device and avoiding positioning errors caused by inclination.

[0049] Further, one end of the diagonal brace 9 is rotatably connected with an ear seat one 91, the ear seat one 91 is slidably connected to the outside of the C-shaped sliding plate two 42 and fixed by a bolt, the other end of the diagonal brace 9 is rotatably connected with an ear seat two 92, the left side of the movable beam 12 is fixedly connected with a C-shaped sliding plate one 14, and the ear seat two 92 is slidably connected to the outside of the C-shaped sliding plate one 14 and fixed by a bolt.

[0050] Specifically, when the rotating beam 4 needs to be unfolded, the bolts used to fix the first ear seat 91 and the second ear seat 92 are loosened, at this time, the first ear seat 91 and the second ear seat 92 are in a slidable state, which is convenient for subsequent adjustment. Then, the relative positions of the first ear seat 91 and the C-shaped sliding plate 42 and the relative positions of the second ear seat 92 and the C-shaped sliding plate 14 are adjusted, so that the diagonal brace 9 can fully play a supporting role when the rotating beam 4 is unfolded, and the unstable or unbalanced condition of the rotating beam 4 during operation is avoided. After the adjustment is completed, the bolts are tightened again.

[0051] Working principle: first step, select the punching position, when the punching position is in the height adjustable range of the adjustable telescopic column 1, the base 2 can be directly placed on the ground, and the extension plate 23 is moved out of the guide groove 22 by a certain length, then the rotating beam 4 is unfolded by ninety degrees, and the rotating beam 4 and the adjustable telescopic column 1 are in a vertical state (use mode as Figure 1 shown). When the punching position is not in the height adjustable range of the adjustable telescopic column 1, the rotating beam 4 is folded back, so that the rotating beam 4 and the adjustable telescopic column 1 remain in a parallel state, at this time, the base 2 needs to be bolted with the side wall of the bridge pile foundation (use mode as Figure 3 shown). Second step, position the base 2 and the rotating beam 4, adjust the position of the base 2 to ensure that the four positioning plates 83 are in contact with the side wall of the bridge pile foundation, at this time, the rotating beam 4 and the side wall of the bridge pile foundation are in a vertical state. Third step, if an inclined hole position is needed, the unfolding angle of the rotating beam 4 can be adjusted again according to the punching angle, and in the adjustment process, the angle line 31 and the pointer 441 can be used for positioning. After the rotating beam 4 is adjusted, the lock nut 442 is tightened to fix the relative position between the rotating beam 4 and the adjustable telescopic column 1, and then the support position of the diagonal brace 9 is adjusted to ensure the secondary support of the rotating beam 4. Fourth step, start the puncher body 6, the puncher body 6 drives the drill bit 62 to rotate through the output shaft 61. Then, the puncher body 6 and the drill bit 62 are moved towards the side wall of the bridge pile foundation by operating the screw lifter 5. In this process, the operator can know the current punching progress by observing the position change of the fixed block 721 on the scale line 712.

[0052] The above is only the preferred embodiment of the present application, and is not used to limit the present application. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made without departing from the technical principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
