Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a convenient structure for cleaning the core of concrete pipe piles. Background Technology

[0002] Prestressed concrete pipe piles are widely used in construction projects. After construction, the inner wall of the pile core often adheres to mud, debris, and other contaminants, requiring cleaning before subsequent foundation pouring or construction, i.e., hole cleaning, to ensure project quality.

[0003] Currently, traditional hole cleaning methods mainly rely on two approaches: one is manual digging using simple tools such as shovels and long sticks, which is not only inefficient and has poor cleaning results, but is also almost powerless for deep pile cores; the other is using specialized large-scale hole cleaning machinery, which is more efficient, but its application scenarios are greatly limited.

[0004] Especially in confined construction environments, the limitations of large-scale hole-cleaning machinery are fully exposed. For example:

[0005] Large equipment cannot be accessed inside existing buildings or in low-ceilinged spaces (such as inside factories or basement additions) due to limitations in floor height and doorway size.

[0006] In narrow streets or densely populated residential areas, the work area is tightly surrounded by existing buildings and walls, and the width of the passage is often insufficient for machinery to pass through or extend its working arm.

[0007] In complex, densely packed pipeline areas (such as chemical plants and power plants), where ground and overhead pipelines crisscross, large machinery does not have enough room to maneuver, posing an extremely high risk of collision.

[0008] At the bottom or near the slope of a deep foundation pit, the working space is limited, making it difficult to lower large equipment and posing safety hazards.

[0009] In these typical confined space conditions, large machinery cannot "enter, deploy, or be used." Therefore, there is an urgent need for a device that is simple in structure, flexible in operation, easy to carry, and can effectively clean the inner wall of the pile core. Utility Model Content

[0010] The purpose of this utility model is to provide a convenient structure for cleaning the core of concrete pipe piles, so as to solve the problems mentioned in the background art.

[0011] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a convenient concrete pipe pile core cleaning structure, comprising:

[0012] spindle;

[0013] The scraper is fixedly installed at the bottom of the spindle;

[0014] The rotating part is installed on the main shaft. When the main shaft is inserted into the core of the concrete pipe pile at different depths, the rotating part can be used to drive the main shaft to rotate, so as to adapt to the main shaft at different depth positions.

[0015] Furthermore, the rotating part includes multiple load-bearing rods and an external operating device;

[0016] The load-bearing rods are evenly spaced and fixed on the main shaft;

[0017] The operating device can be inserted into the support rod, and rotating the operating device will rotate the main shaft.

[0018] Furthermore, the load-bearing bar includes a first member and a second member arranged in parallel, with the main shaft clamped between the first member and the second member;

[0019] The operating device includes a hand-held crossbar and at least two insert rods fixed thereon, with an insertion interface formed between the insert rods for receiving the spindle;

[0020] The insert rod can be inserted into the space between the first rod and the second rod to form a reversible insertion engagement with the load-bearing rod.

[0021] Furthermore, the scraper is a semi-circular sheet structure, with its circular surface in contact with the inner wall of the concrete pipe pile core. There are two scrapers, which are arranged at opposite angles and tilted vertically at the bottom of the main shaft.

[0022] Furthermore, multiple rotating parts are provided and are evenly spaced along the length of the main shaft.

[0023] Furthermore, the main axis has a prism structure;

[0024] The rotating part is slidably sleeved on the outside of the main shaft. The rotating part can slide to different positions of the main shaft to adapt to different insertion depths of the main shaft.

[0025] Furthermore, the rotating part includes a first rod and a second rod. A stop bar is fixedly installed on the side of the second rod, and a sliding cavity is formed between the stop bar and the second rod. The first rod is slidably installed in the sliding cavity. A spring is connected between the first rod and the second rod. Under the tension of the spring, the first rod and the second rod can clamp the main shaft.

[0026] Furthermore, a fixing strip is fixedly installed at the open end of the sliding cavity to prevent the first rod from falling off.

[0027] Furthermore, an outwardly protruding protrusion is fixedly installed on the side of the first member, and the protrusion is located between two stops on the same side.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] The operating device of this utility model can be separated from or integrated into the sliding rotating part. It is lightweight and easy to carry and transport, making it particularly suitable for narrow or complex construction environments where large machinery cannot enter. By setting multiple load-bearing rods or sliding rotating parts, force can be easily applied at different heights of the main shaft to achieve effective cleaning of pile cores at different depths. It is flexible in operation and can be operated by a single person or two people working together. Efficient hole cleaning can be achieved through rotation and pressing actions, solving the problem of difficult cleaning of deep pile cores. Attached Figure Description

[0035] 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.

[0036] Example 1

[0037] Please see 1- Figure 4 As shown in the figure, this embodiment discloses a convenient concrete pipe pile core cleaning structure, including a main shaft 1, which is a metal cylindrical structure, such as a steel reinforcement structure.

[0038] Scraper 2 is fixedly installed at the bottom of main shaft 1, such as... Figure 1 As shown, the scraper 2 is a semi-circular sheet structure, welded and fixed to the bottom of the main shaft 1. In this embodiment, specifically as follows... Figure 1 As shown, there are two scrapers 2, which are arranged at an angle to the bottom of the main shaft 1, and the angles of inclination of the two scrapers 2 are opposite (e.g., Figure 1As shown in the diagram, the diameters of the two scrapers 2 are set according to the inner hole of the concrete pipe pile core, and their circular surfaces are in contact with the inner wall of the concrete pipe pile core.

[0039] Multiple evenly spaced load-bearing rods (such as...) are mounted on the main shaft 1. Figure 1 As shown, there are 3 load-bearing members, including a first member 3 and a second member 4. The first member 3 and the second member 4 are arranged in parallel, clamping the main shaft 1 in the middle. The two members are welded to the main shaft 1 to form a load-bearing member fixed to the main shaft 1.

[0040] It also includes an external operating device, which includes a handheld horizontal bar 5, with two vertically arranged inserts 6 welded to the bottom or side of the handheld horizontal bar 5, such as... Figure 1 As shown, sufficient insertion interfaces are provided between the two insertion rods 6, with the width of the interfaces being at least the same as the diameter of the main shaft 1. This allows the insertion rods 6 to be inserted into the space between the first rod 3 and the second rod 4, while the main shaft 1 is positioned within the insertion interfaces, enabling the connection between the operating device and the load-bearing rod. After connection, external force is used to rotate the insertion rods 6, causing the first rod 3 and the second rod 4 to rotate, which in turn rotates the main shaft 1. During rotation, under the weight of the main shaft 1 and the scraper 2, only slight rotation is needed for the main shaft 1 to move downwards within the concrete pipe pile core. The scraper 2 can scrape away soil and other adhering materials from the inner wall of the concrete pipe pile core, thus cleaning the inner wall. If the scraper 2 encounters significant resistance from the inner wall of the concrete pipe pile core and is difficult to move downwards, the load-bearing rod can be pressed downwards slightly, allowing the main shaft 1 and the scraper 2 to move downwards within the concrete pipe pile core.

[0041] When the main shaft 1 is inserted to different depths into the core of the precast concrete pipe pile, the operating device is connected to the bearing rod at different positions, so that the main shaft 1 at different depths can be rotated, thereby achieving the purpose of cleaning the hole.

[0042] It can be operated by one person or two people. When used by one person, the scraper 2 and the main shaft 1 are inserted into the inner hole of the concrete pipe pile core. As the main shaft 1 is rotated and inserted to different depths, rotating the load-bearing rods at different positions on the main shaft 1 will rotate the main shaft 1 and the scraper 2, thereby cleaning the inner wall of the concrete pipe pile core.

[0043] When used by two people, one person can hold the main shaft 1 and insert the scraper 2 into the core of the concrete pipe pile. For main shaft 1 at different depths, the other person can hold the load-bearing rod at different positions. The other person holds the hand-held horizontal bar 5 and inserts the insertion rod 6 between the first rod 3 and the second rod 4. By rotating the hand-held horizontal bar 5, the main shaft 1 and the scraper 2 can be rotated.

[0044] If the scraper 2 has too much resistance and is difficult to move downwards, one person can press down on the load-bearing rod while another person rotates the hand-held crossbar 5, and the main shaft 1 and scraper 2 can then move downwards inside the concrete pipe pile core.

[0045] In this application, the operating device is designed to be separate, which reduces the weight of the device and makes it easier to carry and use. This is especially suitable for construction environments with limited space, complex geology, and where drilling machinery cannot access the site.

[0046] Example 2

[0047] like Figures 2-4 As shown, the difference from Example 1 is that:

[0048] The main shaft 1 is configured as a prism structure, preferably a cuboid metal rod structure.

[0049] The rotating part is slidably mounted on the outside of the main shaft 1. The structure of the rotating part is as follows:

[0050] like Figures 2-4 As shown, the rotating part includes a first rod 3 and a second rod 4, both of which are cuboid structures. Two stop bars 7 are fixedly mounted on the upper and lower sides of the second rod 4, forming a sliding cavity in the space between the stop bars 7. The first rod 3 is slidably mounted in the sliding cavity. The distance between the two stop bars 7 on the same side is exactly the same as the width of the main shaft 1. The rotating part is installed from the top of the main shaft 1 on the outside of the main shaft 1. During installation, the main shaft 1 is located between the first rod 3 and the second rod 4, and between the two stop bars 7 on the same side of the second rod 4, specifically as shown... Figure 1 As shown, the rotating part can slide up and down along the height direction of the main shaft 1.

[0051] A fixing strip 8 is fixedly installed at the opening end of the sliding cavity to seal the opening and prevent the first rod 3 from falling out of the sliding cavity. A spring 9 is installed between the first rod 3 and the second rod 4. One end of the spring 9 is fixedly connected to the first rod 3, and the other end is fixedly connected to the second rod 4. The spring 9 provides tension or elasticity to the two rods, depending on the actual usage requirements. With the connection of the spring 9, the first rod 3 will not easily fall out of the sliding cavity.

[0052] In a further embodiment, the upper and lower sides of the first rod 3 are fixedly equipped with outwardly protruding protrusions, which are located between two stop bars 7 on the same side, limiting the first rod 3 and preventing it from sliding left and right. Specifically, as shown in the figure... Figure 4As shown. When spring 9 provides tension, to install the rotating part with the main shaft 1, the first rod 3 and the second rod 4 need to be spread apart by hand. The upper end of the main shaft 1 is then inserted into the space formed by the first rod 3, the second rod 4, and the stop rod 7, and the rotating part is slid down along the main shaft 1 to a position near the bottom. When cleaning the core of a concrete pipe pile, hold the main shaft 1, insert the scraper 2 into the core, grip the first rod 3 and the second rod 4 tightly, clamping the main shaft 1 between them, providing clamping force to the main shaft 1. Simultaneously rotate the first rod 3 or the second rod 4 and apply downward pressure. The main shaft 1 can rotate with the scraper 2 while moving downwards, thus cleaning the inner wall of the concrete pipe pile core. When it is necessary to change the position of the rotating part, release the gripping force of the first rod 3 and the second rod 4, and the rotating part can be manually slid upwards. If the tension set on spring 9 is too large, resulting in a large clamping force between the first rod 3 and the second rod 4 and the main shaft 1, one hand can hold the main shaft 1 while the other hand pushes the rotating part upward.

[0053] 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.
