Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction, specifically a device for quickly pulling and lifting buried steel pipes. Background Technology

[0002] In civil engineering construction, the reuse of steel pipes is of great significance for saving costs and improving construction efficiency. However, pulling out steel pipes after they are buried underground faces many challenges. Traditional manual excavation methods are not only inefficient but also labor-intensive, requiring a large amount of manpower and time. For example, on some large construction sites, dozens of buried steel pipes may need to be handled every day, and manual excavation can lead to delays and a significant increase in labor costs. In addition, manual excavation also poses certain safety hazards, such as the possibility of damaging the steel pipes or causing injuries during the excavation process.

[0003] While using large machines for pulling can improve efficiency, this method has several limitations. First, large machinery is expensive, making purchase or rental too costly for some small construction projects. Second, large machines are complex to operate, requiring specialized personnel, which further increases labor costs. Furthermore, large machines have strict site requirements; they cannot be used in confined spaces such as narrow alleyways or inside buildings. Moreover, the pulling process can potentially damage the surrounding environment, such as causing ground subsidence or damage to nearby buildings. Utility Model Content

[0034] Figure 2 This is a three-dimensional schematic diagram of this application.

[0035] Figure 3 This is a top-view diagram of this application. Detailed Implementation

[0036] 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, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0037] like Figure 1-3 As shown: A device for quickly pulling and lifting buried steel pipes includes the following components:

[0038] Rectangular base 1: 50 cm long and 30 cm wide, made of high-strength steel with rust-proof treatment to ensure the stability of the device in various environments.

[0039] Square steel 2: vertically fixed on rectangular base 1, with a height of 1.5 meters, a cross-sectional dimension of 10 cm × 10 cm, made of high-strength steel, and with a hollow internal structure to accommodate spring 4.

[0040] Connection knob 3: Located on the side of square steel 2, it includes an adjustable threaded structure. By rotating the threaded structure, the height of square steel 2 can be adjusted to accommodate buried steel pipes of different lengths.

[0041] Spring 4: A compression spring with an elastic coefficient of 1000 N / m, fitted onto the pressure rod. One end is connected to the telescopic rod, and the other end is connected to the pressure rod to provide the restoring force. When the pressure rod is pressed down, the spring stores elastic potential energy. After the pressure rod is released, the elastic force of the spring causes the pressure rod to automatically return to its original position.

[0042] Pressure bar 5: 1 meter long, 5 centimeters in diameter, made of high-strength aluminum alloy with anti-slip textured surface. Pressure bar 5 connects to the telescopic rod in the middle for the operator to apply pressure.

[0043] Telescopic pole 6: Composed of multiple telescopic segments, each 30 cm long and 8 cm in diameter, made of high-strength steel. One end of the telescopic pole is connected to a square steel bar, and the other end is connected to a lever mechanism. It is adjustable via a connecting knob, allowing for changes in the overall length of the pole.

[0044] Connection knob 7: Used to connect the telescopic rod 6 and the pull-out steel pipe clamp 8 to ensure a stable connection between the two.

[0045] Clamp 8: Includes a clamp body connected to one end of a pressure rod; a clamping part, mounted on the clamp body, for clamping buried steel pipes; the clamping part has a shape matching the surface of the buried steel pipe, and anti-slip textures are provided on the inner side to increase friction with the surface of the buried steel pipe. An adjustment mechanism, mounted on the clamp body, is used to adjust the clamping force of the clamping part, capable of accommodating steel pipes with diameters from 5 cm to 20 cm.

[0046] Operating steps:

[0047] Installation and securing:

[0048] Place the rectangular base on a flat surface to ensure it is stable.

[0049] The clamp is placed on the buried steel pipe, and the clamp is adjusted to ensure a tight fit between the clamp and the steel pipe, thus ensuring sufficient friction.

[0050] Adjusting device height:

[0051] Depending on the length of the buried steel pipe, the height of the square steel is adjusted by rotating the connecting knob, so that the device can adapt to steel pipes of different lengths.

[0052] Pull-out operation:

[0053] The operator stands on one side of the device, holds the pressure rod with their hand, and presses the pressure rod down to generate an upward pulling force using the lever principle.

[0054] When the pressure bar is pressed down, the spring stores elastic potential energy. After the pressure bar is released, the elastic force of the spring causes the pressure bar to automatically return to its original position, ready for the next pressing.

[0055] By repeatedly pressing the pressure rod, the telescopic rod drives the clamp to move upward, thereby pulling the buried steel pipe out of the ground section by section.

[0056] Complete the pull-out:

[0057] Once the buried steel pipe has been completely pulled out of the ground, release the clamps and remove the pipe.

[0058] To continue pulling out other steel pipes, simply repeat the above steps.

[0059] This application utilizes the lever principle and the elasticity of a spring, allowing operators to easily pull buried steel pipes out of the ground simply by repeatedly pressing the pressure rod, significantly reducing labor intensity and improving work efficiency. The device has a simple structure, and the installation and operation process is convenient. A single worker can quickly complete assembly and operation without requiring specialized equipment or complex operating skills. The operation is stable and reliable, avoiding the safety hazards that may arise from manual digging or operating large machinery. Furthermore, this device is suitable for various projects and sites, effectively applicable to both large construction sites and small-scale construction projects.

[0060] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
