Description

Technical Field

[0001] This utility model relates to the field of pile foundation grouting, and in particular to a pile foundation grouting device. Background Technology

[0002] During pile foundation construction, tremie pipes are used to pour concrete into the drilled pile foundation. This typically requires a truck crane for the segmented installation and dismantling of the tremie pipes. Concrete delivery is done using a combination of truck-mounted pumps or direct unloading with a crane. This involves numerous large pieces of equipment with complex components, making installation and dismantling complex and requiring high coordination between the equipment. Furthermore, it incurs significant rental costs. Especially when construction sites are limited, the coordination of conventional processes and machinery becomes difficult to implement smoothly, further increasing the complexity and uncertainty of construction organization.

[0003] A concrete pouring device is a common piece of equipment used for conveying and pouring concrete. Traditional pouring devices are typically designed with a workbench directly in contact with the ground. This workbench not only supports the pouring equipment but also carries construction personnel and materials. However, because it is difficult to completely avoid concrete leakage during the pouring process, leaked concrete often enters the gap between the workbench and the ground, causing the concrete to become sticky after it hardens.

[0004] This stickiness can cause numerous inconveniences for subsequent construction and equipment movement. For example, workbenches are difficult to disassemble and clean, and may even damage equipment or the floor. Furthermore, cleaning up after the concrete has hardened is time-consuming and labor-intensive, reducing construction efficiency and increasing costs. Utility Model Content

[0005] The purpose of this utility model is to provide a pile foundation grouting device to address the problem that traditional grouting devices often cause concrete leakage during concrete grouting, resulting in the workbench sticking to the ground and making it difficult to disassemble and transport the workbench after construction.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pile foundation grouting device includes a work platform, a frame and a grouting port for grouting are provided on the upper end of the work platform, the grouting device is hoisted on the frame, and at least three independently operating lifting devices are provided on the lower end of the work platform, the lifting devices being able to control the lifting and lowering movement of the work platform.

[0008] The injection port is equipped with a baffle assembly at its top, which enables the injection port to be opened and closed.

[0009] This utility model relates to a pile foundation grouting device. By installing a lifting device at the lower end of the workbench, a certain gap is maintained between the workbench and the ground, preventing the workbench from directly contacting the ground. Due to the lifting device, a gap exists between the workbench and the ground, preventing concrete leakage from directly adhering between the workbench and the ground, thus avoiding the sticking problem caused by the concrete after solidification and improving the cleaning efficiency of the equipment. Each lifting device is designed to be individually height-adjustable, allowing the workbench to adapt to different terrains, facilitating equipment movement and position adjustment, and improving the flexibility and adaptability of the construction process. It reduces the time and manpower required to clean the workbench from sticking to the ground, improving construction efficiency and reducing construction costs. By installing a baffle assembly at the grouting port, construction personnel can open or close the baffle at any time as needed to prevent material leakage when the grouting port is not in operation, improving the accuracy of the operation and the cleanliness of the site. At the same time, it prevents construction personnel from accidentally falling from the grouting port when construction is not in progress, ensuring construction safety.

[0010] As a preferred embodiment of this utility model, the frame includes a gantry, the gantry includes two columns, one end of each column is connected to the workbench, a crossbeam is provided between the two columns, and a stiffening rib is provided between each column and the crossbeam.

[0011] By incorporating stiffening ribs between the uprights and crossbeams of the gantry, the overall structural strength and rigidity of the gantry are enhanced, effectively improving its stability and resistance to deformation under heavy loads. The stiffening ribs also evenly distribute stress generated during operation, reducing stress concentration and extending the service life of the gantry.

[0012] As a preferred embodiment of this utility model, the frame further includes diagonal braces, the number of which is the same as the number of uprights, with one end of each diagonal brace connected to the upright and the other end connected to the workbench.

[0013] By adding diagonal braces to the frame and connecting them to the columns and workbench, a more stable triangular support structure is formed, significantly improving the overall stability and anti-overturning capacity of the frame. The diagonal braces effectively distribute the load on the workbench and upper structure, transferring some of the load to the workbench, thereby reducing the pressure on the columns and lowering the risk of deformation. Furthermore, the diagonal brace design further enhances the device's resistance to lateral forces (such as wind loads or vibrations generated during operation), ensuring the safety and reliability of the equipment in complex construction environments. The overall structure is simple yet robust, easy to install and disassemble, and adaptable to various operational needs, further improving the applicability and operational efficiency of the piling machine grouting device.

[0014] As a preferred embodiment of this utility model, the workbench is provided with a lifting device, which includes a pulley block and a winch. The winch is set on the workbench, the pulley block is connected to the crossbeam, and the winch is provided with a wire rope. One end of the wire rope is connected to the winch, and the other end passes around the pulley block and is provided with a barb. The wire rope is connected to the injection device through the barb.

[0015] By installing a lifting device on the workbench and utilizing a combination of pulley blocks and a winch, the operational efficiency and flexibility of the grouting device are improved. The design of the pulley block connection to the crossbeam effectively utilizes the space and structural strength of the frame, allowing the lifting device to operate smoothly over a wide range and adapt to different working conditions. The winch, through the cooperation of the wire rope and the pulley block, achieves flexible lifting and precise positioning of the grouting device, facilitating rapid adjustment of the working position. One end of the wire rope is connected to the winch, and the other end passes through the pulley block and connects to a hook. The design of connecting the hook to the grouting device ensures the stability of the connection and the convenience of operation, reducing the risk of slippage or displacement of the device during hoisting. This structure not only improves the safety of the hoisting process but also reduces the intensity and time costs of manual operation.

[0016] As a preferred embodiment of this utility model, the injection device includes an injection tank, the injection tank is symmetrically provided with connecting rings, each of the connecting rings is provided with a connecting rope, and each of the connecting ropes is connected to the barb.

[0017] By symmetrically arranging connecting rings on the filling tank, and ensuring that each connecting ring is equipped with a connecting rope and a barb, a stable lifting and fixing structure is formed. This symmetrical distribution design effectively balances the force on the filling tank during lifting, preventing the filling tank from tilting or swaying due to uneven loading, thus ensuring the stability of the lifting and the safety of the operation.

[0018] As a preferred embodiment of this utility model, the filling tank is located directly above the filling port, and the filling port and the discharge port of the filling tank are coaxially arranged.

[0019] By positioning the filling tank directly above the filling inlet and aligning the filling inlet and the outlet of the filling tank coaxially, the efficiency and precision of the filling process are ensured. This design minimizes lateral displacement and spillage of material during filling, improving the quality of the filling operation, avoiding material waste and on-site pollution. The coaxial design further optimizes the material flow path, reducing resistance and energy consumption during material transport, thereby improving the overall filling efficiency of the system.

[0020] As a preferred embodiment of this utility model, the injection port is provided with a pair of hinge seats, and the baffle assembly is movably connected to the injection port through the hinge seats.

[0021] By installing a pair of hinged seats at the filling port and movably connecting the baffle assembly to the filling port through the hinged seats, the baffle assembly can be opened and closed flexibly, effectively controlling the material flow during the filling process. This design allows the baffle to be opened or closed as needed, preventing material leakage from the filling port when it is not in operation, thus improving the accuracy of the operation and the cleanliness of the site.

[0022] As a preferred embodiment of the present invention, the baffle assembly includes symmetrically arranged plates, each plate having a hinge portion that is hinged to a hinge seat, and each plate having a handle at the end away from the hinge portion.

[0023] The handle design allows construction workers to directly operate the opening and closing of the baffle manually, reducing the need for auxiliary tools and improving the operational efficiency of the construction process.

[0024] As a preferred embodiment of this utility model, the lifting device includes a piston rod, the top of which is connected to the bottom of the worktable, and the piston rod is used to drive the worktable to perform lifting and lowering movements.

[0025] By adjusting the lifting and lowering of the worktable using the piston rod, the height of the worktable can be precisely adjusted to adapt to different terrains and construction needs, thus enhancing the adaptability and flexibility of the device.

[0026] As a preferred embodiment of this utility model, the lifting device further includes an outer rod, which is a hollow structure; the inner wall of the outer rod is sleeved with the piston rod.

[0027] The sleeve connection between the piston rod and the outer rod simplifies the installation process and facilitates quick disassembly and replacement during subsequent maintenance, thereby improving the operability and maintenance efficiency of the device.

[0028] As a preferred embodiment of this utility model, a sealing plug is provided at the end of the outer rod away from the ground, and the sealing plug is sleeved with the outer wall of the piston rod; a base is provided at the end of the outer rod facing the ground, and the cross-section of the base is larger than the cross-section of the outer rod.

[0029] By setting a sealing plug, the sealing of the lifting device can be guaranteed, ensuring that the piston rod can reciprocate within the outer rod. The cross-section of the base is larger than that of the outer rod, which can effectively improve the stability of the device and prevent the outer rod from tilting or becoming unstable due to external forces during construction, thereby ensuring the balance and safety of the equipment during operation.

[0030] As a preferred embodiment of this utility model, the top of the piston rod is connected to the bottom of the worktable by bolts.

[0031] Bolted connections offer flexibility, making it easier to connect and disassemble the piston rod to the worktable, adapting to on-site construction needs, reducing unnecessary installation difficulties and time, and improving construction efficiency.

[0032] As a preferred embodiment of this utility model, the workbench is equipped with a control console, which is communicatively connected to the lifting device and the winch.

[0033] As a preferred embodiment of this utility model, a power distribution box is provided on the workbench, which is used to supply power to the control console.

[0034] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0035] 1. This utility model is a pile foundation grouting device. By setting a lifting device at the lower end of the workbench, a certain gap is maintained between the workbench and the ground, avoiding direct contact between the workbench and the ground. Due to the setting of the lifting device, a gap exists between the workbench and the ground, so when concrete leaks, it will not directly adhere to the gap between the workbench and the ground, avoiding the adhesion problem caused by the concrete solidifying, and improving the cleaning efficiency of the equipment. Each lifting device is designed to be individually height-adjustable, so that the workbench can adapt to different terrains, facilitating equipment movement and position adjustment, improving the flexibility and adaptability of the construction process. It reduces the time and manpower required to clean the workbench from the ground, improves construction efficiency, and reduces construction costs. Attached Figure Description

The hinge part 1211 is adapted to the hinge seat 111, and the hinge of each plate 121 to the infusion port 11 is realized through the hinge part 1211 and the hinge seat 111.

[0065] Furthermore, each plate 121 is equipped with a handle 122 at the end away from the hinge 1211. Operators can control each plate 121 via the handle 122, thereby opening and closing the injection port 11.
