Description

Technical Field

[0001] This utility model relates to the field of hole excavation device technology, specifically to a hole excavation device for engineering construction pile foundations. Background Technology

[0002] Piling equipment is crucial for ensuring the quality and efficiency of pile foundation construction. It typically involves drilling using mechanical devices such as impact drills, rotary drills, and slewing rigs. These devices utilize different working principles, such as impact and rotation, to break up and expel soil or rock layers from the borehole.

[0003] CN115559661B discloses a pile foundation drilling machine for building engineering, including a base, a servo motor mounted on the front of a front-mounted platform, a winding drum mounted on the output end of the servo motor, a steel wire rope wound around the outer surface of the winding drum, a connecting block mounted on the tail end of the steel wire rope, a hook mounted on the bottom of the connecting block, a connector mounted on the inner surface of the hook, a connecting block two mounted on the bottom of the connector, a connecting rod mounted on the bottom of the connecting block two, a rotating motor mounted on the bottom of the connecting platform, and the main body of the drilling machine mounted on the bottom of the connecting block. This invention, by setting up a base, a steel wire rope, a connector, and a main body for the drilling machine, allows the hook to be fitted onto the connector before using the pile foundation drilling machine, so that the connecting block two can be fixed together with the connecting block one, thereby facilitating the disassembly and assembly of the drilling machine main body according to actual needs and improving the flexibility of use.

[0004] While existing technology CN115559661B has many benefits in its use, it still has the following problems: its dust suppression in the drilling environment is not perfect. As a large amount of dust is generated during the drilling process, the dust in the drilling environment is quite serious, which pollutes the working environment and affects the health of the workers. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a device for excavating pile foundations for engineering construction.

[0006] The technical solution adopted by this utility model to solve its technical problem is a drilling device for pile foundation in engineering construction, including a top plate, a dust collection hood, and a push rod body. The lower outer wall of the top plate is equipped with a circular array of support columns, and a dust collection hood is arranged between the support columns. A connecting groove is opened inside the dust collection hood, and a filter plate is arranged at the lower end of the connecting groove. A circular array of connectors is welded to the lower outer wall of the filter plate. A circular array of connecting columns is welded to the lower outer wall of the dust collection hood. Push rod bodies are arranged on both sides of the upper end of the inner wall of the connecting groove. A vibration rod is installed on the lower outer wall of the push rod body, and a connecting plate is installed on the lower outer wall of the vibration rod. Vibration motors are installed on both sides of the upper outer wall of the connecting plate.

[0007] By adopting the above technical solutions, the top rod, support column, and base plate can restrict the vertical movement of the drill rod, ensuring that the drill rod can accurately drill holes in the ground. Furthermore, the dust collection hood can collect soil and dust during the digging process, enabling dust collection and cleaning of the digging environment and ensuring its cleanliness.

[0008] Specifically, a base plate is welded to the outer wall of the lower end of the support column, and a circular array of fixing blocks is welded to the outer wall of the base plate. Fixing holes are provided inside the fixing blocks.

[0009] By adopting the above technical solution, the fixing holes opened inside the fixing block make it easy to firmly install the device on the ground, preventing displacement or tipping during the digging process and improving construction safety.

[0010] Specifically, a drill rod is provided inside the top plate, and a connector is installed on the outer wall of the upper end of the drill rod.

[0011] By adopting the above technical solution, the connector facilitates the connection between the drill rod and the drilling equipment, enabling automated or semi-automated drilling operations according to actual usage needs. This design improves construction efficiency and reduces the labor intensity of workers.

[0012] Specifically, the outer wall of the dust hood is welded with a circular array of support members, which are slidably installed on the outside of the support column. A bolt is threadedly connected to one side of the outer wall of the support member, and the bolt penetrates the support member and contacts the outer wall of the support column. A dust suction pipe is inserted and installed on one side of the upper end of the inner wall of the dust hood.

[0013] By adopting the above technical solution, the dust hood can be slidably installed on the outside of the support column through the support component and can be fixed by bolts. This design allows the dust hood to be adjusted in height and angle as needed to adapt to different digging requirements. At the same time, the design of the dust suction pipe facilitates the removal of dust and debris from the connecting groove, keeping the working environment clean. Thus, workers can move the dust hood to the top of the hole during the digging process and collect the soil and dust raised during the digging process through the dust suction pipe and connecting groove.

[0014] Specifically, the connector is slidably installed on the outside of the connecting column, a nut is threaded to one side of the lower outer wall of the connecting column, a spring is provided on the outside of the connecting column, and the connector is elastically connected to the nut through the spring.

[0015] By adopting the above technical solution, the nut ensures the stability of the spring's position, and the spring force supports the connector and filter plate, ensuring the stability of the filter plate's position inside the connecting groove. This ensures the filter plate covers the lower end of the dust collection hood, preventing soil from splashing into the connecting groove during the digging process and avoiding affecting the smooth flow of dust collection. The filter plate can be driven down by the connecting plate, causing it to detach from the connecting groove. This allows the filter plate to achieve stable vibration position through the spring, preventing damage from excessive vibration. The vibration generated by the vibrating motor is transmitted to the filter plate, which can vibrate and clean the soil clogging the filter holes, ensuring the unobstructed flow of the filter holes.

[0016] Specifically, sealing rings are attached to both sides of the inner wall of the connecting groove, and the two sealing rings are respectively attached to the outer ring and inner ring of the filter plate.

[0017] By adopting the above technical solution, the sealing ring effectively prevents dust and debris from leaking out from the gap between the filter plate and the connecting groove. This design improves dust collection efficiency and also protects the filter plate and the connecting groove from being clean and intact.

[0018] Specifically, a protective pad is adhered and fixed to the lower outer wall of the connecting plate, and the protective pad is in contact with the upper outer wall of the filter plate.

[0019] By adopting the above technical solution, the protective pad contacts the upper outer wall of the filter plate. This design prevents the connecting disc from causing wear or damage to the filter plate during vibration, thus extending the service life of the filter plate. At the same time, the protective pad also plays a role in shock absorption and cushioning, improving the stability and durability of the device.

[0020] The beneficial effects of this utility model are:

[0021] (1) The engineering construction pile foundation excavation device described in this utility model has a dust suction pipe designed to easily remove dust and debris from the connecting trench, maintain a clean working environment, and collect the soil and dust raised during the excavation process.

[0022] (2) The engineering construction pile foundation excavation device of the present invention can stabilize the vibration position of the filter plate through the spring and prevent the filter plate from being damaged due to excessive vibration. The vibration generated by the vibration motor is transmitted to the filter plate, which can vibrate and clean the soil blocking the filter hole of the filter plate, and ensure the unobstructed flow of the filter hole.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the present invention provides a drilling device for engineering construction pile foundations, comprising a top plate 1, a dust collection hood 2, and a push rod body 3. A circular array of support columns 11 is installed on the lower outer wall of the top plate 1. A dust collection hood 2 is positioned between the support columns 11. A connecting groove 21 is opened inside the dust collection hood 2. A filter plate 24 is installed at the lower end of the connecting groove 21. A circular array of connectors 25 is welded to the lower outer wall of the filter plate 24. A circular array of connecting columns 26 is welded to the lower outer wall of the dust collection hood 2. Push rod bodies 3 are installed on both sides of the upper end of the inner wall of the connecting groove 21. A vibration rod 31 is installed on the lower outer wall of the push rod body 3. A connecting plate 32 is installed on the lower outer wall of the vibration rod 31. Vibration motors 33 are installed on both sides of the upper outer wall of the connecting plate 32.

[0032] During use, the top rod, support column 11, and base plate 12 can restrict the vertical movement of the drill rod 14, ensuring that the drill rod 14 can accurately drill holes in the ground. The dust collection hood 2 collects soil and dust during the digging process, enabling dust collection and cleaning of the digging environment and ensuring its cleanliness. The vibration rod 31 ensures the stability of the vibration position of the connecting plate 32, and the push rod body 3 can adjust the position of the connecting plate 32 to ensure that the protective pad 34 is in controlled contact with the filter plate 24.

[0033] To fix the usage location, for example, such as Figure 1 As shown, a base plate 12 is welded to the outer wall of the lower end of the support column 11, and a circular array of fixing blocks 13 is welded to the outer wall of the base plate 12. Fixing holes are opened inside the fixing blocks 13.

[0034] When in use, the fixing holes inside the fixing block 13 make it easy to firmly install the device on the ground, preventing displacement or tipping during the digging process and improving construction safety.

[0035] For example, to make a hole, such as Figure 2 As shown, a drill rod 14 is installed inside the top plate 1, and a connector 15 is installed on the outer wall of the upper end of the drill rod 14.

[0036] When in use, the connector 15 facilitates the connection between the drill rod 14 and the drilling equipment, enabling automated or semi-automated drilling operations according to actual needs. This design improves construction efficiency and reduces the labor intensity of workers.

[0037] For vacuuming, for example, such as Figure 3 As shown, the outer wall of the dust hood 2 is welded with a circular array of support members 23. The support members 23 are slidably installed on the outside of the support column 11, and a bolt is threaded on one side of the outer wall of the support member 23. The bolt penetrates the support member 23 and contacts the outer wall of the support column 11. A dust suction pipe 22 is inserted and installed on one side of the upper end of the inner wall of the dust hood 2.

[0038] In use, the dust hood 2 can be slidably installed on the outside of the support column 11 via the support member 23 and can be fixed by bolts. This design allows the dust hood 2 to be adjusted in height and angle as needed to adapt to different digging requirements. At the same time, the design of the dust suction pipe 22 facilitates the removal of dust and debris from the connecting groove 21, keeping the working environment clean. Thus, during the digging process, the worker can move the dust hood 2 to the top of the hole and collect the dust raised during the digging process through the dust suction pipe 22 and the connecting groove 21.

[0039] For flexible connectivity, for example, such as Figure 5 As shown, the connector 25 is slidably installed on the outside of the connecting post 26. A nut 27 is threadedly connected to one side of the lower outer wall of the connecting post 26. A spring 28 is provided on the outside of the connecting post 26. The connector 25 is elastically connected to the nut 27 through the spring 28.

[0040] During use, nut 27 ensures the stability of spring 28's position, and the elasticity of spring 28 supports connector 25 and filter plate 24, ensuring the stability of filter plate 24's position inside the connecting groove 21. This also ensures that filter plate 24 blocks the lower end of dust hood 2, preventing soil from splashing into the connecting groove 21 during the digging process and avoiding affecting the smooth collection of dust. Filter plate 24 can also be driven down by the connecting plate, causing it to detach from the connecting groove 21. This allows filter plate 24 to achieve stable vibration position via spring 28, preventing damage due to excessive vibration. The vibration generated by vibrating motor 33 is transmitted to filter plate 24, which can vibrate and clean the soil clogging the filter holes, ensuring the unobstructed flow of the filter holes.

[0041] For sealing, exemplarily, such as Figure 3 As shown, sealing rings are attached to both sides of the inner wall of the connecting groove 21, and the two sealing rings are respectively attached to the outer ring and inner ring of the filter plate 24.

[0042] During use, the sealing ring effectively prevents dust and debris from leaking out from the gap between the filter plate 24 and the connecting groove 21. This design improves dust collection efficiency while also protecting the filter plate 24 and the connecting groove 21 from damage and damage.

[0043] For protection, for example, such as Figure 4 As shown, a protective pad 34 is adhered and fixed to the lower outer wall of the connecting plate 32, and the protective pad 34 is in contact with the upper outer wall of the filter plate 24.

[0044] During use, the protective pad 34 contacts the upper outer wall of the filter plate 24. This design prevents the connecting disc 32 from causing wear or damage to the filter plate 24 during vibration, thus extending the service life of the filter plate 24. At the same time, the protective pad 34 also plays a role in shock absorption and cushioning, improving the stability and durability of the device.

[0045] When this utility model is in use, the drill rod 14 is connected to the drilling equipment through the connector 15. When the drilling equipment is started, the drill rod 14 begins to move vertically downward to drill a hole in the ground. The top rod, support column 11 and base plate 12 together restrict the vertical movement of the drill rod 14 to ensure the accuracy of drilling.

[0046] At the same time, the external vacuum cleaner is activated and connected to the vacuum pipe 22, so that the soil and dust generated during the digging process are sucked into the connecting groove 21. The soil and dust are filtered by the filter plate 24. Larger soil particles are blocked by the filter plate 24, while smaller dust particles are sucked away through the filter holes.

[0047] During or after the drilling process, the push rod body 3 pushes the connecting plate 32 to move, causing the protective pad 34 to push the filter plate 24, causing the filter plate 24 to disengage from the connecting groove 21. The vibration motor 33 is then started, and the vibration is transmitted to the filter plate 24 through the connecting plate 32, the vibration rod 31 and the protective pad 34. Under the action of vibration, the mud blocking the filter holes of the filter plate 24 is cleared away, ensuring the unobstructed flow of the filter holes.

All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
