Description

A novel electrically controlled hydraulic punching device Technical Field

[0001] This utility model relates to the technical field of hydraulic punching equipment, specifically a novel electrically controlled hydraulic punching device. Background Technology

[0002] Hydraulic drilling technology is a widely used and effective operating method in many engineering fields such as coal mining, geological exploration, and tunnel construction. Its core principle is to use high-pressure water flow to impact the target rock strata or coal seam. The powerful kinetic energy of the water flow breaks the rock or coal body, thereby forming the required holes to achieve engineering objectives such as gas extraction, geological exploration, ventilation, and slag removal.

[0003] Traditional hydraulic perforation equipment mainly consists of a high-pressure water pump, water supply pipeline, and perforation nozzle. In actual operation, the high-pressure water pump pressurizes water and delivers it to the perforation nozzle through the pipeline. The nozzle then sprays the high-pressure water at a specific angle and speed onto the target area to complete the perforation operation. However, this traditional device has revealed many problems in practical applications. The perforation parameters of traditional hydraulic perforation equipment, such as water pressure, flow rate, and spray angle, are complex and not precise enough to adjust. Adjusting the water pressure and flow rate usually requires manual operation of the high-pressure water pump valves, making real-time, continuous, and precise control difficult. Adjusting the spray angle often requires stopping the machine, disassembling the nozzle, or changing the connection method of the water supply pipeline, which is not only cumbersome but also seriously affects the operation efficiency. This difficulty in adjusting the perforation parameters makes it impossible to flexibly optimize the perforation parameters according to different geological conditions and operational requirements, thus affecting the perforation effect and operation quality. Summary of the Invention

[0004] The purpose of this invention is to provide a novel electrically controlled hydraulic punching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel electrically controlled hydraulic punching device, comprising a housing, an electric cylinder connecting base fixedly installed inside the housing, a telescopic electric cylinder installed inside the electric cylinder connecting base, a top end cap installed at the output end of the telescopic electric cylinder, an electric cylinder pressure stabilizing plate protecting the outer tube fixedly installed inside the housing, and a power cord connector fixedly installed inside the housing.

[0006] Preferably, one end of the outer casing is internally threaded with an end cap connector, and the end of the outer casing away from the end cap connector is threaded with a bottom end cap.

[0007] Preferably, the power cord connector has a male snap-fit ​​internal fitting installed inside, and the end of the male snap-fit ​​internal fitting away from the power cord connector is inserted into the inside of the bottom end cover.

[0008] Preferably, the bottom end cap is internally threaded with a bottom end cap insulating component, and a copper rod is internally snapped into the bottom end cap insulating component.

[0009] Preferably, a cross-head bolt is threaded on one side of the electric cylinder connecting base, and one end of the cross-head bolt is threaded into the interior of one end of the telescopic electric cylinder.

[0010] Preferably, the output end of the telescopic electric cylinder is movably connected through the end cover connector, and threaded holes are provided inside both sides of the top end cover, and two cross-head bolts are threaded into the inside of each threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by placing the device inside the mechanical water jet of the hydraulic cavity-making water jet device in the well, the top end cap is moved by extending and retracting the output end of the telescopic electric cylinder. The movement of the top end cap will change the water flow channel inside the water jet, so that the water flow can flow in a predetermined direction, thereby achieving precise control of the water flow direction inside the water jet. Precise water flow control can significantly improve the cutting efficiency and cavity-making quality of the water jet, and reduce energy consumption and equipment wear.

[0012] Alternatively, the device can be placed inside the drill pipe. By extending and retracting the output end of the telescopic electric cylinder, the top end cap can be moved. By adjusting the position of the top end cap, the water flow can be made to impact the drill bit more concentratedly, improving the cooling effect of the drill bit and the drilling speed. Furthermore, by changing the direction of the water flow, it can better carry rock cuttings and prevent rock cuttings from clogging the drill pipe. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4. This utility model provides a technical solution: a novel electrically controlled hydraulic punching device, including a housing 1. An electric cylinder connecting base 12 is fixedly installed inside the housing 1. A telescopic electric cylinder 9 is installed inside the electric cylinder connecting base 12. A top end cap 6 is installed at the output end of the telescopic electric cylinder 9. An electric cylinder pressure stabilizing plate protective outer tube 14 is fixedly installed inside the housing 1. A power cord connector 8 is fixedly installed inside the housing 1. An end cap connector 10 is threadedly connected to one end of the housing 1. A bottom end cap 2 is threadedly connected to the end of the housing 1 away from the end cap connector 10. A male internal connector 7 is snapped into the power cord connector 8. The end of the male internal connector 7 away from the power cord connector 8 is inserted into the bottom end cap 2. A bottom end cap insulating member 3 is threaded into the bottom end cap 2, and a copper rod 4 is snapped into the bottom end cap insulating member 3.

[0020] The working principle of the above technical solution is as follows: First, an external power supply is connected to the copper rod 4. The copper rod 4 transmits current to the power cord connector 8 through the male-female internal connector 7. Then, the power cord connector 8 can transmit a large current to the telescopic electric cylinder 9, thereby enabling the telescopic electric cylinder 9 to be started and stopped. In use, the device can be placed inside the mechanical water jet of the downhole hydraulic cavity-making water jet device. By extending and retracting the output end of the telescopic electric cylinder 9, the top end cap 6 is moved. The movement of the top end cap 6 changes the water flow channel inside the water jet, allowing the water to flow in a predetermined direction, thereby achieving precise control of the water flow direction inside the water jet. Precise water flow control can significantly improve the cutting efficiency and cavity-making quality of the water jet, reduce energy consumption and equipment wear. Similarly, the device can also be placed inside the drill pipe. By extending and retracting the output end of the telescopic electric cylinder 9, the top end cap 6 is moved. By adjusting the position of the top end cap 6, the water flow can be made to impact the drill bit more concentratedly, improving the cooling effect of the drill bit and the drilling speed. Furthermore, by changing the water flow direction, rock cuttings can be better carried, preventing rock cuttings from clogging the drill pipe.

[0021] In another implementation scheme, as shown in Figures 1-4, a cross-head bolt 13 is threadedly connected to the inside of one side of the electric cylinder connecting base 12, and one end of the cross-head bolt 13 is threadedly connected to the inside of one end of the telescopic electric cylinder 9. The output end of the telescopic electric cylinder 9 moves through the end cover connector 10. Threaded holes 5 are opened on both sides of the top end cover 6, and cross-head bolts 11 are threadedly connected to the inside of each threaded hole 5.

[0022] The end of the outer shell 1 can be fixed to the inner side of the electric cylinder connecting base 12 by the cross head bolt 13, ensuring the stability of the telescopic electric cylinder 9 inside the outer shell 1. In addition, the top end cover 6 can be installed on the outer side of the output end of the telescopic electric cylinder 9 by the cross head bolt 11 and the threaded hole 5, which facilitates the assembly and disassembly of the top end cover 6 and the telescopic electric cylinder 9.

[0023] Working principle: First, an external power supply is connected to the copper rod 4. The copper rod 4 transmits current to the power cord connector 8 through the male-female internal connector 7. Then, the power cord connector 8 transmits a large current to the telescopic electric cylinder 9, thereby enabling the telescopic electric cylinder 9 to be started and stopped. In use, this device can be placed inside the mechanical water jet of the hydraulic cavity-forming water jet device in the well. By extending and retracting the output end of the telescopic electric cylinder 9, the top end cover 6 is moved. The movement of the top end cover 6 changes the water flow channel inside the water jet, allowing the water to flow in a predetermined direction. This achieves precise control of the water flow direction inside the water jet. Precise water flow control can significantly improve the cutting efficiency and cavity-forming quality of the water jet, reduce energy consumption and equipment wear. Similarly... Alternatively, the device can be placed inside the drill rod. By extending or retracting the output end of the telescopic electric cylinder 9, the top end cap 6 can be moved. By adjusting the position of the top end cap 6, the water flow can be made to impact the drill bit more concentratedly, improving the cooling effect of the drill bit and the drilling speed. Furthermore, by changing the direction of the water flow, rock cuttings can be better carried, preventing rock cuttings from clogging the drill rod. The end of the outer shell 1 can be fixed to the inner side of the electric cylinder connecting base 12 by the provided cross head bolt 13, ensuring the stability of the telescopic electric cylinder 9 inside the outer shell 1. In addition, the top end cap 6 can be installed on the outer side of the output end of the telescopic electric cylinder 9 by the provided cross head bolt 11 and threaded hole 5, facilitating the assembly and disassembly of the top end cap 6 and the telescopic electric cylinder 9.
