Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0021] like Figures 1 to 4 As shown, a water-grinding drill device of an embodiment of the present invention is used to drill holes in a base. For example, the area of ​​the base that needs to be replaced is A. For this, the water-grinding drill device needs to be placed on the track of the base, and the water-grinding drill device needs to be moved to one side of the corresponding base and drill holes. After the drilling of one side of the base is completed, the water-grinding drill device needs to be moved to the other side of the corresponding base and drill holes. Finally, the corresponding base is lifted up to achieve the removal of the base.

[0022] Specifically, the above-mentioned water mill drilling equipment includes a frame 30 and a water mill drilling assembly. The upper surface of the base 10 is symmetrically provided with a track 20 extending in the length direction; the two outer sides of the lower part of the frame 30 are provided with running wheels 50, and the running wheels 50 are slidably connected with the track 20 so that the frame 30 can move along the extension direction of the track 20. The water mill drilling mechanism 40 includes a box body 41, a lifting power member 45 and a water mill drilling assembly. The box body 41 is connected to the frame 30. The water mill drilling assembly is located at the front side of the box body 41 and is connected to the lifting power member 45. The lifting power member 45 is arranged at the top of the box body 41, and is used to drive the water mill assembly to be lifted and lowered in the vertical direction.

[0023] For example, the travel wheel 50 is provided to be slidably connected with the track 20 on the base, so as to move the frame 30 along the extension direction of the track 20, thereby driving the box 41 connected to the frame 30 to move, so that the water drill assembly follows the movement of the box 41, thereby adjusting the water drill assembly to the desired drilling position. For example: after completing the drilling of the area on one side of the base 10, when it is necessary to transfer to the area on the other side of the base 10 for drilling, since the outer side of the frame 30 is provided with the travel wheel 50, and the travel wheel 50 is slidably connected with the track 20, so that the frame 30 can be pushed to move relative to the base 10, and the water drill assembly can be transferred to the other side of the base 10.

[0024] For example, the lifting power member 45 is used to drive the water-grinding drill assembly to move in the vertical direction, so that automatic feeding can be achieved without manual feeding, which can greatly improve the efficiency of drilling holes and avoid the errors and laborious problems caused by manual operation. In addition, the lifting power member 45 can be a hydraulic cylinder, or a power component in the prior art that can drive the water-grinding drill assembly to move up and down, which is not limited.

[0025] The water-grinding drilling equipment based on the above technical features, by using the two outer sides of the lower part of the frame 30 to set the walking wheels 50, and the walking wheels 50 are slidably connected with the track 20 of the base, so that the frame 30 can drive the box 41 to move, and then transfer the water-grinding drill assembly to the position where the drilling hole is required, and then use the lifting power part 45 to drive the water-grinding drill assembly to lift in the vertical direction, so as to realize automatic feeding, without relying on manpower for feeding, greatly improving the efficiency of drilling, and avoiding the error and troublesome problems caused by manual operation, solving the current problem that the feeding control of the water-grinding drill bit 43 relies on manpower, resulting in insufficient drilling control accuracy and troublesome manual feeding. In addition, the walking wheels 50 connected to the frame 30 are cleverly used to slide along the extension direction of the track 20, so that the frame 30 can be directly pushed to move, without the need for the staff to use the lifting method to drill, which can save the staff's physical strength and help improve the accuracy of drilling.

[0026] In one embodiment, the lifting power part is specifically a hydraulic cylinder, and the water-grinding drill assembly also includes a pressure-maintaining controller, which is connected to the lifting power part so that the pressure threshold can be set according to the actual situation. When the water-grinding drill assembly drills a hole on the base, if the pressure value detected by the pressure-maintaining controller exceeds the pressure threshold, the pressure-maintaining controller controls the hydraulic cylinder to cut off the hydraulic supply; if the pressure value detected by the pressure-maintaining controller is less than the pressure threshold, the pressure-maintaining controller controls the hydraulic cylinder to increase the hydraulic feed until the pressure of the hydraulic cylinder reaches the pressure threshold again, and then maintains the feed of the hydraulic cylinder. In this way, it can be ensured that the water-grinding drill assembly can be controlled to drill a hole on the base with a relatively stable downward pressure.

[0027] In a possible implementation, at least one group of water drill assemblies is provided, and all water drill assemblies are spaced apart on the front side of the box body 41 in the lateral direction, and a plurality of lifting power members 45 are provided, and the plurality of lifting power members 45 correspond one-to-one to the water drill assemblies to drive the respective water drill assemblies to be lifted and lowered in the vertical direction. It should be noted that the "at least one group is provided" mentioned above refers to one or more groups, which can be determined according to the actual situation and is not limited to this. Specifically in this embodiment, four groups of water drill assemblies are provided, and correspondingly, four lifting power members 45 are provided, and the four lifting power members 45 correspond one-to-one to the four groups of water drill assemblies, and the four groups of water drill assemblies are arranged side by side in the vertical direction, and then the corresponding water drill assemblies are driven to be lifted and lowered by utilizing the corresponding lifting assemblies, so that drilling can be performed simultaneously, which is beneficial to improving the efficiency of drilling.

[0028] In a possible embodiment, two clamping members 60 are further included, which are axially symmetrically connected to both sides of the frame 30, a clamping space is formed between the two clamping members 60, and the two clamping members 60 are respectively in contact with the two outer side surfaces of the base 10, so that the base 10 is clamped in the clamping space. In other words, after the frame 30 is moved to a suitable position, the two clamping members 60 need to be used to abut the two outer side surfaces of the base 10, so that the base 10 is clamped in the clamping space, ensuring that the frame 30 will not move randomly during the subsequent drilling process, thereby ensuring the accuracy of the drilling.

[0029] Specifically, the clamping member 60 includes a horizontal beam 61, a vertical beam 62 and a clamping plate 63. Connecting strips 130 extend outward from the two outer sides of the frame 30. The connecting strips 130 are arranged in the storage cavity. The horizontal beam 61 can be retractably stored in the storage cavity. The upper end of the vertical beam 62 is connected to the end of the horizontal beam 61 extending out of the accommodating cavity. The lower end of the vertical beam 62 is connected to the clamping plate 63. The clamping plate 63 is used to abut against the outer side surface of the base 10.

[0030] For example, if the position of the water drill assembly needs to be adjusted, the end of the cross beam 61 extending out of the accommodating cavity is pulled out in a direction away from the base 10 to drive the vertical beam 62 away from the base 10, so that the clamping plate 63 is separated from the abutment against the base 10, and then the frame 30 can be pushed to move relative to the base 10, until the water drill assembly is moved to the desired position, and then the cross beam 61 is pushed in a direction close to the base 10, so that the cross beam 61 is retracted into the accommodating cavity, so that the clamping plate 63 is abutted against the outer side of the base 10, and then the frame 30 is fixed on the base 10 under the mutual cooperation of the clamping plates 63 of the two clamping members 60, so as to avoid the frame 30 from moving randomly during the drilling process, thereby ensuring the accuracy of the drilling. In other words, the clamping member 60 has a simple structure and can quickly lock or loosen the frame 30, so as to quickly adjust the position of the water drill assembly.

[0031] In a possible embodiment, the adjusting rod 70 and the adjusting hand wheel 80 are further included. The adjusting rod 70 passes through the vertical beam 62 in the horizontal direction and can move relative to the vertical beam 62. The clamping plate 63 is connected to the end of the adjusting rod 70 close to the base 10. The adjusting hand wheel 80 is connected to the end of the adjusting rod 70 away from the base 10, and is used to drive the adjusting rod 70 to rotate, so as to drive the clamping plate 63 to approach or move away from the base 10. That is to say, after the cross beam 61 is adjusted to a suitable position, the adjusting hand wheel 80 is rotated to drive the adjusting rod 70 to rotate, thereby driving the clamping plate 63 to approach the base 10, until the clamping plate 63 is tightly abutted against the base 10, so that the two opposite clamping plates 63 cooperate to lock the frame 30, so as to prevent the frame 30 from moving randomly during the drilling process, thereby ensuring the accuracy of the drilling.

[0032] In a possible implementation, the two outer sides of the frame 30 are extended outward with clamps 90, the clamps 90 are located outside the connecting strip 130, and one end of the clamps 90 away from the frame 30 is bent downward to form a hook portion, which is used to buckle with the track 20. In this way, the hook portion of the clamps 90 is buckled with the track 20, so that there is no risk of derailment when the frame 30 moves along the track 20, and the normal movement of the frame 30 is ensured.

[0033] In a possible embodiment, the water drill assembly includes a water drill bit 43 and a rotating motor 44. A guide rod 42 is provided inside the box 41 in the vertical direction. The rotating motor 44 is located at the front side of the box 41 and is slidably connected to the guide rod 42. The output shaft of the rotating motor 44 is vertically toward the bottom of the box 41. The water drill bit 43 is connected to the output shaft of the rotating motor 44. The output shaft of the lifting power part 45 is connected to the rotating motor 44 to drive the rotating motor 44 to lift and lower in the vertical direction to drive the water drill bit 43 to move.

[0034] Exemplarily, by setting a guide rod 42 in the vertical direction inside the box 41, and slidingly connecting the rotating motor 44 to the guide rod 42, and then using the lifting power part 45 arranged on the top of the box 41 to drive the rotating motor 44 to move in the vertical direction, it can drive the water-abrasive drill bit 43 to automatically feed without relying on manpower for feeding, thereby greatly improving the efficiency of drilling, and at the same time avoiding the errors and troublesome problems caused by manual operation, and solving the current problem that the feeding control of the water-abrasive drill bit 43 relies on manpower, resulting in insufficient drilling control accuracy and troublesome manual feeding.

[0035] In addition, the guide rod 42 can be made of steel to ensure that the supporting guide rod 42 has sufficient rigidity to avoid deformation or breakage due to poor rigidity of the guide rod 42 during the lifting and lowering of the rotating motor 44.

[0036] In one embodiment, a mounting hole 47a for connecting to the output end of the lifting power member 45 is provided in the middle of the slide 47, and a through hole 47b for sliding connection to the guide rod 42 is provided on the slide 47, and the through hole 47b is located outside the connection hole. In this way, the output end of the lifting power member 45 can be connected to the mounting hole 47a to achieve the connection between the slide 47 and the lifting power member 45, the structure is simple, and the assembly and disassembly are convenient. The slide 47 is connected to the guide rod 42 by using the through hole 47b to achieve the sliding connection between the slide 47 and the guide rod 42.

[0037] In a possible implementation, a slide 47 is further included, and the slide 47 at least partially extends into the inner cavity and is slidably connected to the guide rod 42, and the slide 47 is connected to the rotary motor 44, and the output end of the lifting power member 45 is connected to the slide 47. That is, when adjusting the feed of the water-grinding drill 43, the lifting power member 45 drives the slide 47 to slide on the guide rod 42 to drive the rotary motor 44 to move up and down, and then drives the water-grinding drill 43 connected to the rotary motor 44 to move, thereby realizing automatic control of the feed amount, and avoiding errors and laborious problems caused by manual operation.

[0038] In a possible embodiment, a pusher 120 is further included, a slide bar 100 is arranged on the frame 30 in the transverse direction, a slide table 110 is slidably connected to the slide bar 100, the box 41 is connected to the slide table 110, and the pusher 120 is connected to the frame 30 and the slide table 110, and is used to drive the slide table 110 to slide on the slide bar 100, so as to drive the box 41 to move back and forth in the transverse direction. In this way, the slide table 110 is driven to slide along the slide bar 100 by the pusher 120, and since the box 41 is connected to the slide table 110, the drilling position of the water-grinding drill bit 43 can be adjusted according to the drilling requirements, the structure is simple, and automatic adjustment can be achieved without manual operation.

[0039] In a possible embodiment, the walking wheel 50 includes a wheel body 51 and a roller shaft 52 connected to the wheel body 51, the side of the wheel body 51 close to the frame 30 is connected to the frame 30, the side of the wheel body 51 away from the frame 30 is in contact with the side wall of the track 20, and the roller shaft 52 is in rolling contact with the top surface of the track 20.

[0040] Since the movement of the water-grinding drill mechanism 40 is relatively slow and almost unobservable, in one embodiment, an indication component 46 is further included, and the indication component 46 includes an upward indicator light 461 and a downward indicator light 462, both of which are electrically connected to the controller and are used to indicate the running direction of the water-grinding drill bit 43. Thus, in this embodiment, the upward indicator light 461 and the downward indicator light 462 can be used to cooperate with each other to indicate the running direction of the water-grinding drill bit 43, so that the user can clearly know the moving direction of the water-grinding drill bit 43.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
