Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically a grouting device for pile foundation construction. Background Technology

[0002] Grouting involves injecting certain solidifying materials, such as cement, lime, or other chemical materials, into the foundation soil within a certain range to fill cracks and pores, prevent foundation leakage, and improve the integrity, strength, and stiffness of the soil. Pile foundations, as building foundations, have high requirements for soil strength and often require grouting before construction. An existing high-efficiency grouting device for pile foundations (Announcement No.: CN214940168U) has the following disadvantages in use:

[0003] The equipment occupies a significant amount of vertical space. For transport vehicles, the increased height of the equipment may prevent them from passing under low bridges or tunnels, increasing the complexity and cost of transportation. Therefore, this patent proposes a pile foundation construction grouting device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a grouting device for pile foundation construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pile foundation grouting device, comprising a base plate, a turntable rotatably connected to the top of the base plate, a first motor fixed to the bottom of the base plate, the output end of the first motor passing through the base plate and fixed to the turntable, a fixing frame fixed to the top of the turntable, an installation frame rotatably connected between the inner walls of the two sides of the fixing frame, and a first electric telescopic rod rotatably connected between the inner wall of the bottom end of the fixing frame and the installation frame.

[0006] Preferably, a movable rod is slidably connected inside the mounting frame, a connecting rod is inserted into one end of the movable rod, a fixing member is fixed to the end of the connecting rod away from the movable rod, a second electric telescopic rod is fixed between the movable rod and the fixing member, a third electric telescopic rod is fixed to the bottom end of the fixing member, a mounting plate is fixed to the telescopic end of the third electric telescopic rod, a grouting pipe is installed at the bottom end of the mounting plate, and a conveying pipe is fixedly connected to the outer wall of the grouting pipe.

[0007] Preferably, a mounting box is fixed to the top of the base plate, a battery is installed inside the mounting box, a connecting frame is fixed to the top of the mounting box, a solar panel is installed on the top of the connecting frame, and an inspection door is installed on one side of the mounting box.

[0008] Preferably, a lead screw is rotatably connected between the inner wall of the top end and the inner wall of the bottom end of the mounting frame. A slider is screwed onto the outer wall of the lead screw. The slider and the moving rod are fixed together. One end of the mounting frame is provided with a mounting groove. A second motor is installed in the mounting groove. The output end of the second motor passes through the mounting frame and is fixed to the lead screw.

[0009] Preferably, a flange is fixed to the top of the grouting pipe, and multiple screws are threaded between the flange and the mounting plate.

[0010] Preferably, the bottom end of the base plate is equipped with multiple casters, the end of the base plate away from the turntable is equipped with a push rod, and the top end of the base plate is fixed with a controller. The controller is electrically connected to the first motor, the first electric telescopic rod, the second electric telescopic rod, the third electric telescopic rod, the battery, the solar panel, and the second motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting the first electric telescopic rod to drive the installation frame to rotate, the installation frame is made to be in a vertical state, and subsequent grouting work can be carried out. When grouting is not required, the first electric telescopic rod drives the installation frame to rotate towards the bottom plate, so that it is stored on the top of the bottom plate, reducing the vertical space occupied and avoiding the inability of transport vehicles to pass through low bridges or tunnels, which would increase the complexity and cost of transportation.

[0013] In addition, by installing batteries and solar panels, the solar panels can convert sunlight into electrical energy, which is then stored in the batteries. When grouting work is required, this energy can power the equipment in the grouting device that requires electricity. This not only reduces electricity costs and improves energy efficiency, but also allows the batteries to be charged in advance when sunlight is insufficient. This enables the device to be moved to the location where construction is needed, reducing the inconvenience caused by insufficient power cords or the lack of power at the construction site.

[0019] 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.

[0020] Grouting is the process of injecting certain solidifying materials, such as cement, lime, or other chemical materials, into the foundation soil within a certain range to fill cracks and pores in the soil, prevent foundation leakage, and improve the integrity, strength, and rigidity of the soil. Among them, pile foundations, as building foundations, have high requirements for the strength of the foundation, and often require grouting before construction. The pile foundation construction grouting device provided by this utility model uses a first electric telescopic rod 9 to drive the installation frame 4 to rotate, so that the installation frame 4 is in a vertical state, and subsequent grouting work can be carried out. When grouting is not needed, the first electric telescopic rod 9 drives the installation frame 4 to rotate towards the base plate 1, so that it is stored above the base plate 1.

[0021] like Figures 1-4As shown, this utility model provides a technical solution: a grouting device for pile foundation construction, including a base plate 1, a turntable 2 rotatably connected to the top of the base plate 1, a first motor fixed to the bottom of the base plate 1, the output end of the first motor passing through the base plate 1 and fixed to the turntable 2, a fixing frame 3 fixed to the top of the turntable 2, an installation frame 4 rotatably connected between the inner walls of the two sides of the fixing frame 3, and a first electric telescopic rod 9 rotatably connected between the inner wall of the bottom end of the fixing frame 3 and the installation frame 4. A moving rod 5 is slidably connected inside the installation frame 4, a connecting rod 11 is inserted into one end of the moving rod 5, a fixing member 12 is fixed to the end of the connecting rod 11 away from the moving rod 5, a second electric telescopic rod 10 is fixed between the moving rod 5 and the fixing member 12, a third electric telescopic rod 13 is fixed to the bottom end of the fixing member 12, an installation plate 14 is fixed to the telescopic end of the third electric telescopic rod 13, a grouting pipe 15 is installed at the bottom end of the installation plate 14, and a conveying pipe 16 is fixedly connected to the outer wall of the grouting pipe 15. A mounting box 21 is fixed to the top of the base plate 1. A storage battery is installed inside the mounting box 21. A connecting frame is fixed to the top of the mounting box 21. A solar panel 22 is installed on the top of the connecting frame. An inspection door is installed on one side of the mounting box 21.

[0022] It is important to note that by starting the first motor, the turntable 2 rotates, which in turn adjusts the position of the grouting pipe 15, facilitating grouting at different locations. This improves automation, work efficiency, and safety. The first electric telescopic rod 9 rotates the mounting frame 4, making it vertical for subsequent grouting. When grouting is not needed, the first electric telescopic rod 9 rotates the mounting frame 4 towards the base plate 1, retracting it above the base plate 1 and reducing vertical space occupation. This prevents transport vehicles from being unable to pass under low bridges or tunnels, thus avoiding increased transport complexity and costs. Furthermore, the second electric telescopic rod 10 moves the fixing component 12, adjusting the horizontal distance of the grouting pipe 15. The device is designed for easy grouting at different locations. An external pump is connected to the delivery pipe 16, which is positioned at the grout storage location. During grouting, the third electric telescopic rod 13 is activated to move the grouting pipe 15 downwards, grouting the pile foundation. A battery and solar panel 22 are installed, allowing the solar panel to convert sunlight into electricity, which is then stored in the battery. When grouting is needed, this electricity powers the equipment within the grouting system, reducing electricity costs and improving energy efficiency. Furthermore, when sunlight is insufficient, an external power source can be connected to charge the battery in advance, allowing the device to be moved to the desired construction location, reducing inconvenience caused by insufficient power cord length or lack of power at the construction site.

[0023] like Figure 2 and Figure 4As shown, a lead screw 7 is rotatably connected between the inner walls of the top and bottom ends of the mounting frame 4. A slider 8 is screwed onto the outer wall of the lead screw 7. The slider 8 and the moving rod 5 are fixed together. One end of the mounting frame 4 has a mounting groove, in which a second motor 6 is installed. The output end of the second motor 6 passes through the mounting frame 4 and is fixed to the lead screw 7. A flange 17 is fixed to the top of the grouting pipe 15. Multiple screws are screwed between the flange 17 and the mounting plate 14. Multiple casters 20 are installed at the bottom of the base plate 1. A push rod 19 is installed at the end of the base plate 1 away from the turntable 2. A controller 18 is fixed to the top of the base plate 1. The controller 18 is electrically connected to the first motor, the first electric telescopic rod 9, the second electric telescopic rod 10, the third electric telescopic rod 13, the battery, the solar panel 22, and the second motor 6. The first motor and the second motor 6 have a self-locking function.

[0024] It should be noted that in some special pile foundation construction sites, such as the foundation engineering of high-rise buildings, it is necessary to move the grouting pipe 15 to a higher position so that the grout can be injected into a higher position of the pile body through the grouting pipe 15. At this time, the second motor 6 is started, the second motor 6 drives the lead screw 7 to rotate, the lead screw 7 rotates and drives the slider 8 to move upward, the slider 8 moves and drives the moving rod 5 to move upward. In this way, the grouting pipe 15 can be moved upward, which is convenient for grouting the higher pile foundation. In this solution, the electrical components are controlled by the matching controller 18, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the field. It is only used and not improved. In addition, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0025] 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 embodiments and their equivalents.
