Description

Technical Field

[0001] This utility model relates to the field of concrete pier demolition technology, specifically a concrete pier demolition device. Background Technology

[0002] A concrete pier is a composite structure made of concrete, consisting of a pier and a platform, commonly used in the foundations of various building projects. The concrete pier structure consists of two parts: the pier (usually a square or round column supporting the platform) and the platform (a larger horizontal surface supporting buildings or other heavy objects). Concrete piers can bear the weight of a building and distribute it evenly across the surrounding ground, thus enhancing the building's stability and earthquake resistance. They also firmly secure the building to the ground, ensuring its stability and safety. In addition to supporting buildings, concrete piers can also support other important equipment or machinery. When concrete piers undergo engineering modifications or reconstruction, demolition equipment is required for dismantling.

[0003] Traditional concrete pier demolition typically involves using tools such as sledgehammers, chisels, and crowbars. This process is not only time-consuming and delays the project, but also deforms the reinforcing steel, rendering it unusable. To address these issues, some concrete pier demolition devices utilize water-pressure cutters to cut the reinforcing steel and concrete, while preserving the steel for recycling. This reduces demolition time, ensures project progress, and avoids steel deformation, allowing for future use. However, this method, due to the spray nozzles used to cut and demolish the concrete pier, causes water and mud to splash outwards from the cutting area, expanding pollution at the construction site and affecting the quality of subsequent construction. Therefore, a concrete pier demolition device is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete pier demolition device to solve the aforementioned technical problems that not only expand pollution at the construction site but also affect the quality of subsequent construction.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a concrete pier demolition device, comprising:

[0008] A support base and a liquid storage tank disposed on the upper surface of the support base, wherein the liquid outlet end of the liquid storage tank is connected to a high-pressure pump body, and a liquid guide pipe is connected to the liquid outlet end of the high-pressure pump body, and a fixed base is connected to the liquid outlet end of the liquid guide pipe, and adjustment components are installed on both sides of the fixed base, and a cutting nozzle is connected to the liquid outlet end of the fixed base.

[0009] A driven wheel is disposed on the outside of the cutting nozzle and is rotatably connected to the fixed base. A driving wheel is engaged on the upper part of the driven wheel, and a first drive motor is coaxially connected to the end of the driving wheel. The first drive motor is rotatably connected to the fixed base.

[0010] A transparent shell is mounted on the surface of a fixed base, with a transparent cover installed at one end. A scraper is tightly fitted to the inner walls of both the transparent shell and the transparent cover, and the scraper is connected to a driven wheel. By bringing the transparent cover close to the cutting area of ​​the concrete pier, a high-pressure pump delivers liquid from the storage tank along the guide pipe and the fixed base to the inside of the cutting nozzle. The liquid is then sprayed from the cutting nozzle to cut the concrete pier. During the cutting process, splashed water and mud are intercepted by the conical transparent cover, causing them to flow downwards towards the cover. An externally powered first drive motor drives the drive wheel on the fixed base, causing the driven wheel to rotate. This rotation of the drive wheel on the fixed base scrapes away water and mud from the inner walls of the transparent shell and the transparent cover. This interception of splashed water and mud reduces pollution at the construction site and ensures the quality of subsequent construction. Furthermore, it cleans the water and mud from the inner walls of the transparent shell and the transparent cover, allowing the cut location of the concrete pier to be accurately determined and preventing errors in the cutting process.

[0011] Preferably, the adjustment assembly includes a horizontal housing and a vertical housing, with the vertical housing having an overall U-shaped design and casters installed around the bottom of the support base. The support base can be moved using the casters.

[0012] Preferably, a second drive motor is mounted on the outer side of the transverse housing, and a horizontal lead screw is rotatably connected to the inner cavity of the transverse housing. The second drive motor is connected to an external power source to drive the horizontal lead screw to rotate on the transverse housing and adjust the direction of the horizontal lead screw.

[0013] Preferably, the second drive motor is coaxially connected to the horizontal lead screw, and a sliding block is sleeved on the surface of the horizontal lead screw, and the sliding block is connected to the vertical housing. The sliding block drives the vertical housing to translate along the inner wall of the horizontal housing according to the direction of the horizontal lead screw.

[0014] Preferably, a third drive motor is mounted on the upper surface of each vertical housing, and a vertical lead screw is rotatably connected to the inner cavity of each vertical housing, with the lead screw coaxially connected to the third drive motor. The third drive motor, powered by an external power source, drives the vertical lead screw to rotate on the vertical housing and adjusts the direction of rotation of the lead screw. Simultaneously, the two sets of third drive motors can rotate synchronously in the same direction or in opposite directions through sensors or other mechanisms. This is existing technology and will not be described in detail here.

[0015] Preferably, each vertical lead screw is fitted with a sliding plate, and the sliding plate is connected to the fixed seat. The sliding plate moves the fixed seat up and down along the inner wall of the vertical box according to the direction of the vertical lead screw, thereby adjusting the cutting position of the cutting nozzle on the concrete pier.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a concrete pier demolition device, which has the following features:

[0018] Beneficial effects:

[0019] This concrete pier demolition device works by placing a transparent cover near the cutting area of ​​the concrete pier. A high-pressure pump delivers liquid from a storage tank along a guide pipe and a fixed base to the inside of the cutting nozzle. The liquid is then sprayed from the nozzle to cut the concrete pier. During the cutting process, water and mud splashing in all directions are intercepted by the cone-shaped transparent cover, causing them to flow downwards towards the cover. An externally powered first drive motor drives a drive wheel on the fixed base. As the drive wheel rotates on the fixed base, a scraper scrapes the inner walls of the transparent shell and cover, intercepting splashed water and mud. This not only reduces pollution at the construction site but also ensures the quality of subsequent construction. Simultaneously, it cleans water and mud from the inner walls of the transparent shell and cover, allowing the cutting area of ​​the concrete pier to be accurately determined, preventing errors in the cutting location.

[0026] This utility model provides a technical solution: a concrete pier demolition device, comprising: (see details) Figure 1 , Figure 3 , Figure 4 Support base 1, and liquid storage tank 3 disposed on the upper surface of support base 1, wherein the liquid outlet end of liquid storage tank 3 is connected to high pressure pump body 4, and liquid guide pipe 5 is connected to the liquid outlet end of high pressure pump body 4, and liquid guide pipe 5 is connected to the liquid outlet end of liquid guide pipe 5, and fixed base 6 is connected to the fixed base 6, and adjustment components 7 are installed on both sides of fixed base 6, and cutting nozzle 8 is connected to the liquid outlet end of fixed base 6.

[0027] Driven wheel 9 is located outside the cutting nozzle 8 and is rotatably connected to fixed base 6. Drive wheel 10 is engaged on the upper part of driven wheel 9 and the end of drive wheel 10 is coaxially connected to first drive motor 11. First drive motor 11 is rotatably connected to fixed base 6.

[0028] A transparent shell 12 is disposed on the surface of the fixed base 6, and a transparent cover 13 is installed at the end of the transparent shell 12. A scraper 14 is tightly attached to the inner wall of the transparent shell 12 and the transparent cover 13, and the scraper 14 is connected to the driven wheel 9. After the transparent cover 13 is brought close to the cutting area of ​​the concrete pier, the high-pressure pump 4 delivers the liquid in the storage tank 3 along the liquid guide pipe 5 and the fixed seat 6 to the inside of the cutting nozzle 8. The liquid is then sprayed out by the cutting nozzle 8 to cut the concrete pier. During the cutting process, water stains and mud splashing in all directions are intercepted by the cone-shaped transparent cover 13, causing the water stains and mud to flow downwards towards the transparent cover 13. The first drive motor 11, connected to an external power source, drives the drive wheel 10 on the fixed seat 6.

A second drive motor 16 is mounted on the outside of the horizontal housing 15, and a horizontal lead screw 17 is rotatably connected to the inner cavity of the horizontal housing 15. The second drive motor 16, powered by an external power source, drives the horizontal lead screw 17 to rotate on the horizontal housing 15 and adjusts the direction of the horizontal lead screw 17. The second drive motor 16 is coaxially connected to the horizontal lead screw 17, and a sliding block 18 is fitted on the surface of the horizontal lead screw 17, and the sliding block 18 is connected to the vertical housing 19.

Each lead screw 21 has a sliding plate 22 fitted onto its surface, and the sliding plate 22 is connected to the fixed base 6. The sliding plate 22, according to the direction of the lead screw 21, drives the fixed base 6 to move up and down along the inner wall of the vertical housing 19, thereby adjusting the cutting position of the cutting nozzle 8 on the concrete pier.

The liquid is then sprayed out by the cutting nozzle 8 to cut the concrete pier. During the cutting process, water stains and mud splashing in all directions are intercepted by the cone-shaped transparent cover 13, causing the water stains and mud to flow downwards towards the transparent cover 13. The first drive motor 11, connected to an external power source, drives the drive wheel 10 on the fixed seat 6, causing the drive wheel 10 to drive the driven wheel 9 to rotate on the fixed seat 6. When in motion, the scraper 14 scrapes the inner walls of the transparent shell 12 and the transparent cover 13.
