Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile driving technology in civil engineering, and in particular to a pile driving device for civil engineering. Background Technology
[0002] Piling is used to solidify the foundation of a building. It involves driving wooden or stone piles into the ground using specialized equipment. Piles of various materials are driven, pressed, vibrated, or screwed into the foundation soil. Existing piling equipment includes large and small piling machines. Large machines are mostly used for piling of building foundations and are bulky, while small piling machines are mostly handheld devices that are operated manually to work on smaller piles.
[0003] However, traditional small-scale piling devices pose certain safety hazards during piling. During the piling process, there is a lack of fixation between the device and the wooden pile. Also, because the device vibrates up and down during use, when the bottom of the device detaches from the surface of the wooden pile, it will fall directly to the ground, which may cause great injury to the operator's feet.
[0004] For example, during construction, when a worker is driving a pile with a handheld pile driver, the contact plate at the bottom of the pile driver may detach from the pile surface due to vibration or slippage. If the device is too heavy, the worker may not be able to lift it in time, causing the device to fall on the worker's foot. The powerful impact can cause foot fractures and irreversible serious damage. Utility Model Content
[0005] This utility model discloses a piling device for civil engineering, which aims to solve the technical problem that during the piling process, there is a lack of fixation between the device and the wooden pile, and because the device vibrates up and down during use, when the bottom of the device detaches from the surface of the wooden pile, it will directly smash into the ground, which may cause great injury to the footsteps of the operator.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A piling device for civil engineering includes an outer cylinder and a top cover fixed to its top. A cross-shaped fixing frame is fixedly connected inside the outer cylinder, and a hydraulic device is fixedly connected to the middle of the cross-shaped fixing frame. A control panel is fixedly connected to the top of the top cover. The device also includes: a piling mechanism: the piling mechanism includes a fixed cylinder fixedly connected to the bottom of the outer cylinder. A strip-shaped hole is opened on the surface of the fixed cylinder, and a roller is rotatably connected inside the strip-shaped hole. A piling plate is provided inside the fixed cylinder, and a reinforcing rod is fixedly connected to the top of the piling plate; and a shock absorption mechanism: the shock absorption mechanism is fixedly connected to the top of the outer cylinder.
[0008] In this solution, the pile top can be fixed simultaneously with the pile driving mechanism, connecting the device to the pile. When the top of the pile is inserted into the fixed cylinder, it contacts the roller inside the slotted hole. The roller's design, with the size decreasing from top to bottom, allows for connection of piles of different sizes, ensuring the device fits on top of the pile. This prevents the bottom of the device from detaching from the pile surface due to vibration during pile driving, thus avoiding injury to the user. The roller design also prevents the pile from getting stuck in the fixed cylinder, thus avoiding the problem of the device being unable to be removed after pile driving.
[0009] In a preferred embodiment, the shock absorption mechanism includes an extension seat fixedly connected to the top of the outer cylinder, a slider slidably connected inside the extension seat, limit rods slidably connected to the slider near its four corners, a strong spring fixedly connected to the bottom of the slider, and a handle fixedly connected to the outside of the slider.
[0010] The number of extension seats is two, and the two extension seats are symmetrically fixedly connected to the left and right sides of the top of the outer cylinder. The upper and lower ends of the limiting rod are fixedly connected to the upper and lower surfaces of the internal cavity of the extension seat. The bottom end of the strong spring is fixedly connected to the bottom of the inside of the extension seat. The handle surface is provided with a rubber sleeve to increase friction.
[0011] The shock absorption mechanism can buffer the vibration generated during pile driving, reducing the impact of vibration on the human body. When the worker holds the handle to drive the pile, the impact will be transmitted to the hand along the handle. Under the action of the strong spring inside the shock absorption mechanism, the vertical vibration generated by the impact can be absorbed, reducing the vibration of the device, thus allowing the worker to hold the handle more stably and preventing the device from slipping out of their hand.
[0012] As described above, the device includes an outer cylinder and a top cover fixed to its top. A cross-shaped fixing frame is fixedly connected inside the outer cylinder, and a hydraulic device is fixedly connected to the center of the cross-shaped fixing frame. A control panel is fixedly connected to the top of the top cover. The device also includes: a piling mechanism: the piling mechanism includes a fixed cylinder fixedly connected to the bottom of the outer cylinder. A strip-shaped hole is opened on the surface of the fixed cylinder, and a roller is rotatably connected inside the strip-shaped hole. A piling plate is installed inside the fixed cylinder, and a reinforcing rod is fixedly connected to the top of the piling plate; and a shock-absorbing mechanism: the shock-absorbing mechanism is fixedly connected to the top of the outer cylinder. The piling device for civil engineering provided by this utility model has the technical effect of connecting the device to the top of the device during the piling process, preventing the device from hitting the ground during piling, and simultaneously buffering the impact, allowing the operator to perform piling operations more safely and stably.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0019] The piling device disclosed in this utility model for civil engineering is mainly used in scenarios where the pile body and the device lack connection during the piling process, and the device is at risk of detaching from the pile body, which may cause injury to the operator.
[0020] Reference Figure 1 , Figure 2 and Figure 3 A piling device for civil engineering includes an outer cylinder 1 and a top cover 2 fixed on top of it. A cross-shaped fixing frame 3 is fixedly connected inside the outer cylinder 1, and a hydraulic device 4 is fixedly connected in the middle of the cross-shaped fixing frame 3. A control panel 5 is fixedly connected to the top of the top cover 2. The device is characterized by further including: a piling mechanism: the piling mechanism includes a fixed cylinder 6, which is fixedly connected to the bottom of the outer cylinder 1. A strip-shaped hole 7 is opened on the surface of the fixed cylinder 6, and a roller 8 is rotatably connected inside the strip-shaped hole 7. A piling plate 9 is provided inside the fixed cylinder 6, and a reinforcing rod 10 is fixedly connected to the top of the piling plate 9; and a shock absorption mechanism: the shock absorption mechanism is fixedly connected to the top of the outer cylinder 1.
[0021] Specifically, the piling mechanism can fix the top of the pile while driving the pile, connecting the device to the pile. When the top of the pile is inserted into the fixed cylinder 6, it contacts the roller 8 inside the strip hole 7. The roller 8 is designed from large to small from top to bottom, which can connect piles of different sizes, so that the device is fitted on the top of the pile, avoiding the bottom of the device from detaching from the pile surface due to vibration during the piling process, which could cause injury to the human body.
[0022] There are four strip holes 7, which are equidistantly arranged on the surface of the fixed cylinder 6. The reinforcing rod 10 is slidably connected to the top of the fixed cylinder 6. The top of the piling plate 9 is fixedly connected to the bottom of the hydraulic device 4. The design of the reinforcing rod 10 can reinforce the edge of the piling plate 9 and prevent uneven stress on the piling plate 9.
[0023] The rollers 8 consist of twelve rollers, which are symmetrically connected in groups of three inside the slot 7. The rollers 8 in the same group are arranged in descending order of size. The design of the rollers 8 can connect the pile body while avoiding the problem of the pile body getting stuck in the fixed cylinder 6 and being unable to remove the device after the pile is driven.
[0024] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the shock absorption mechanism includes an extension seat 11 fixedly connected to the top of the outer cylinder 1, a slider 12 slidably connected inside the extension seat 11, a limit rod 13 slidably connected near the four corners of the slider 12, a strong spring 14 fixedly connected to the bottom of the slider 12, and a handle 15 fixedly connected to the outside of the slider 12.
[0025] Specifically, the shock absorption mechanism can buffer the vibration generated during pile driving and reduce the impact of vibration on the human body. When the worker holds the handle 15 to drive the pile, the impact will be transmitted to the hand along the handle 15. Under the action of the strong spring 14 inside the shock absorption mechanism, the vertical vibration generated by the impact can be absorbed, reducing the vibration of the device, so that the worker can hold the handle 15 more stably and prevent the device from falling out of the hand.
[0026] The device includes two extension seats 11, which are symmetrically fixed to the left and right sides of the top of the outer cylinder 1. The upper and lower ends of the limiting rod 13 are fixedly connected to the upper and lower sides of the internal cavity of the extension seat 11. The bottom end of the strong spring 14 is fixedly connected to the bottom of the extension seat 11. The handle 15 is provided with a rubber sleeve to increase friction. The design of the rubber sleeve on the surface of the handle 15 allows the operator to better grip the handle 15 and prevent the device from falling out of control.
[0027] Reference Figure 1 and Figure 2In a preferred embodiment, the top cover 2 is fixedly connected to the top of the outer cylinder 1 by screws, and the control panel 5 controls the hydraulic device 4 via wiring.
[0028] Specifically, the removable design of the top cover 2 facilitates the inspection and maintenance of the connection lines between the control panel 5 and the hydraulic device 4.
[0029] Working principle: During use, the fixing cylinder 6 at the bottom of the device is placed on top of the pile. When the top of the pile of different sizes contacts the roller 8, the pile can be fixed in the fixing cylinder 6. At the same time, the center of the top of the pile is aligned with the center of the pile driving plate 9, ensuring that the subsequent pile driving force is uniform and there will be no deviation. The operator holds the handle 15 and starts the hydraulic device 4 through the control panel 5 on the top of the top cover 2. The pile driving plate 9 at the lower end of the hydraulic device 4 drives the pile driving plate 9 to smash the top of the pile and drive the pile into the ground. The reinforcing rod 10 set on the top of the pile driving plate 9 can reinforce the pile driving plate 9 and share the pressure generated by the impact. During the pile driving process, the vibration generated will be transmitted along the device to the handle 15. The vibration will cause the outer cylinder 1 to move upward. At this time, the strong spring 14 inside the extension seat 11 will buffer the impact and reduce the vibration transmitted to the handle 15, allowing the operator to hold the handle 15 better and prevent the device from getting out of control.
[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
