Description

A vibration damping device for drilling rigs used in engineering surveying Technical Field

[0001] This utility model relates to the field of drilling rig vibration reduction technology, specifically a drilling rig vibration reduction device for engineering survey. Background Technology

[0002] Drilling rigs are commonly used exploration equipment in engineering surveys. However, during drilling, due to formation resistance, the rotation of drilling tools, and other factors, drilling rigs are prone to significant vibrations. These vibrations not only reduce drilling efficiency but may also damage or loosen other components of the drilling rig, thus affecting its normal operation.

[0003] Existing vibration damping devices for drilling rigs used in engineering surveys require workers to hold the handle for extended periods during operation, which can cause injury due to the vibration. Additionally, prolonged operation of the drill bit can cause it to overheat, requiring manual cooling or a period of inactivity before restarting. This not only wastes water resources but also delays the project's progress. Summary of the Invention

[0004] The purpose of this utility model is to provide a vibration damping device for drilling rigs used in engineering surveys. The device uses a piston rod to move up and down, which drives a moving block to move and fills a small amount of gas into the air inlet sleeve. The gas enters the air supply pipe through the air supply channel and then enters the air bladder from the air supply pipe. The air bladder expands, reducing the vibration amplitude of the device on the worker's hands and avoiding injury to the workers, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping device for drilling rigs used in engineering surveys, comprising a housing, a handle fixedly connected to the housing, an inflation mechanism fixedly mounted on the handle, a cooling mechanism fixedly mounted on the housing, a first support plate fixedly mounted inside the housing, a motor fixedly mounted on the upper end of the first support plate, a drill bit fixedly mounted on the output end of the motor, multiple sets of first damping dampers and multiple sets of second damping dampers respectively arranged oppositely around the first support plate, multiple sets of piston sleeves fixedly mounted on the upper end of each set of piston sleeves, a piston rod fixedly mounted on the upper end of each piston rod, a spring fixedly mounted inside the piston rod, and a second support plate fixedly mounted on the upper end of the piston rod, the second support plate being disposed inside the housing;

[0007] The inflation mechanism includes a moving block fixedly mounted on one end of the piston rod, an air inlet sleeve slidably connected to the moving block, the air inlet sleeve being located at the lower end of the second support plate, the air inlet sleeve penetrating the second support plate and connected to an air supply channel, an air supply pipe connected to the air supply channel, the air supply pipe connecting to an airbag, the airbag being fixedly mounted on the handle, and the airbag being connected to an exhaust pipe.

[0008] Preferably, two sets of first holes are provided on one side of the outer shell where it connects to the water pipe.

[0009] Preferably, a second pressure valve is fixedly installed on the exhaust pipe, and a first pressure valve is installed on the water pipe near the nozzle.

[0011] Preferably, the second support plate is provided with a second hole, the size of which is adapted to the gas pipeline.

[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. 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.

[0024] Please refer to Figures 1 to 6. This utility model provides a vibration damping device for drilling rigs used in engineering surveys, including a housing 1. A handle 11 is fixedly connected to the housing 1. An inflation mechanism 3 is fixedly installed on the handle 11. A cooling mechanism 2 is also fixedly installed on the housing 1. A first support plate 15 is also fixedly installed inside the housing 1. A motor 16 is fixedly installed at the upper end of the first support plate 15. A drill bit 12 is fixedly installed at the output end of the motor 16. Multiple sets of first damping dampers 13 and multiple sets of second damping dampers 14 are respectively arranged opposite to each other around the first support plate 15. Multiple sets of piston sleeves 17 are also fixedly installed at the upper end of the first support plate 15. A piston rod 19 is fixedly installed at the upper end of each set of piston sleeves 17. A spring 191 is fixedly installed inside the piston rod 19. A second support plate 18 is also fixedly installed at the upper end of the piston rod 19. The second support plate 18 is located inside the housing 1.

[0025] Cooling mechanism 2 includes a water tank 21 fixedly installed on the upper end of the outer shell 1. One end of the water tank 21 is connected to a water pipe 22. An exhaust pipe 24 is fixedly installed on the water pipe 22. A nozzle 26 is also fixedly connected to one end of the water pipe 22.

[0026] The inflation mechanism 3 includes a moving block 34 fixedly mounted on one end of the piston rod 19. An air inlet sleeve 35 is slidably connected to the moving block 34. The air inlet sleeve 35 is located at the lower end of the second support plate 18. The air inlet sleeve 35 passes through the second support plate 18 and is connected to an air supply channel 31. An air supply pipe 32 is connected to the air supply channel 31. The air supply pipe 32 is connected to an airbag 33. The airbag 33 is fixedly mounted on the handle 11 and is connected to the exhaust pipe 24.

[0027] Before using this device, fill the water tank 21 with water. The worker holds the air bag 33 with both hands, points the drill bit 12 toward the ground, and turns on the motor 16. After starting, the drill bit 12 begins to work on the ground. After starting to work, the first damping damper 13 and the second damping damper 14 dampen the forces around them respectively. At the same time, the piston rod 19 moves back and forth inside the piston sleeve 17 to dampen the forces above and below. At the same time, the piston rod 19 moves up and down, driving the moving block 34 to move and filling a small amount of gas into the air inlet sleeve 35. The gas enters the air supply pipe 32 through the air supply channel 31, and then enters the air bag 33 from the air supply pipe 32. The air bag 33 expands, reducing the vibration amplitude of the device on the worker's hands and avoiding injury to the worker.

[0028] After working for a period of time, the airbag 33 is filled with a certain amount of gas. The second pressure valve 25 on the exhaust pipe 24 senses the pressure and opens, expelling a portion of the gas inside the airbag 33 into the water pipe 22. The first pressure valve 23 on the water pipe 22 senses a certain pressure and opens, discharging the cold water in the cooling mechanism 2 through the nozzle 26 to cool the drill bit 12, preventing damage caused by excessively high working temperature and extending the service life of the drill bit 12.

[0029] In an optional embodiment, two sets of first holes are provided at the connection between one side of the housing 1 and the water pipe 22.

[0030] It should be noted that the outer casing 1 protects the water tank 21 inside, preventing damage to the water tank 21 and affecting the use of the device. At the same time, the water pipe 22 passes through the outer casing 1 to deliver the water inside the water tank 21.

[0031] In an optional embodiment, a second pressure valve 25 is fixedly installed on the exhaust pipe 24, and a first pressure valve 23 is installed on the water pipe 22 near the nozzle 26.

[0032] It should be noted that the second pressure valve 25 ensures that the airbag 33 will not be filled with too much gas, which could cause an explosion and injure the operator. The first pressure valve 23 ensures that the water pipe 22 will not continuously spray water onto the drill bit 12, thus avoiding indiscriminate water spraying and wasting resources.

[0033] In an optional embodiment, two sets of first damping dampers 13 are disposed opposite to each other on both sides of the first support plate 15, and two sets of second damping dampers 14 are also disposed opposite to each other on both sides of the first support plate 15, and both the first damping dampers 13 and the second damping dampers 14 are connected to the outer shell 1.

[0034] It should be noted that the first damping damper 13 and the second damping damper 14 work together to reduce the vibration of the horizontal surface.

[0035] In an optional embodiment, the second support plate 18 is provided with a second hole, the size of which is adapted to the gas pipe 32.

[0036] It should be noted that the gas supply pipe 32 delivers the gas squeezed by the moving block 34 from inside the second support plate 18 to the air bag 33, reducing the damage to the operator caused by vibration.

[0037] In an optional embodiment, a third hole is provided on the side of the air intake sleeve 35 near the moving block 34.

[0038] It should be noted that air is introduced through the third hole on the air intake sleeve 35 to ensure that a small amount of gas is injected into the airbag 33 with each vibration.

[0039] Working principle: Before using this device, fill the water tank 21 with water. The worker holds the air bag 33 with both hands, points the drill bit 12 toward the ground, and turns on the motor 16. After starting, the drill bit 12 begins to work on the ground. After starting to work, the first damping damper 13 and the second damping damper 14 dampen the surrounding forces respectively. At the same time, the piston rod 19 moves back and forth inside the piston sleeve 17 to dampen the vertical forces. At the same time, the vertical movement of the piston rod 19 drives the moving block 34 to move, filling a small amount of gas into the air inlet sleeve 35. The gas enters the air supply pipe 32 through the air supply channel 31, and then enters the air bag 33 from the air supply pipe 32. The air bag 33 inflates, reducing the vibration amplitude of the device on the worker's hands and avoiding injury to the worker.

[0040] After working for a period of time, the airbag 33 is filled with a certain amount of gas. The second pressure valve 25 on the exhaust pipe 24 senses the pressure and opens, expelling a portion of the gas inside the airbag 33 into the water pipe 22. The first pressure valve 23 on the water pipe 22 senses a certain pressure and opens, discharging the cold water in the cooling mechanism 2 through the nozzle 26 to cool the drill bit 12, preventing damage caused by excessively high working temperature and extending the service life of the drill bit 12.

[0041] The outer casing 1 protects the water tank 21 inside, preventing damage to the water tank 21 and affecting the use of the device. At the same time, the water pipe 22 passes through the outer casing 1 to send the water inside the water tank 21 out. The second pressure valve 25 ensures that the air bag 33 will not be filled with too much gas, which could cause an explosion and injure the operator. The first pressure valve 23 ensures that the water pipe 22 will not spray water onto the drill bit 12 continuously, avoiding indiscriminate water spraying and wasting resources. Air is introduced through the third hole on the air inlet sleeve 35 to ensure that a small amount of gas can be injected into the air bag 33 with each vibration.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
