Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measurement technology in geotechnical engineering, and specifically relates to a protective and storage device for a three-dimensional earth pressure cell. Background Technology
[0002] The use of 3D earth pressure cells often requires carrying large bags for storage, leading to inconvenience during measurement work. This is particularly problematic for measurements requiring the carrying of multiple 3D earth pressure cells. Improper storage and handling over a long period can cause wear and tear on the sensors, resulting in decreased measurement accuracy. Furthermore, environmental factors such as humidity and sediment can damage the sensors. Data cables are frequently collected during 3D earth pressure cell use, but traditional methods often involve manual winding and stacking of the cables. This is time-consuming and labor-intensive, and manual winding results in tangled and knotted cables that become difficult to handle later. Furthermore, improper storage over time can also cause damage to the data cables. Utility Model Content
[0003] The purpose of this invention is to provide a protective and storage device for three-dimensional earth pressure cells, addressing the significant inconvenience often encountered when carrying multiple three-dimensional earth pressure cells for measurement work, as mentioned in the background. Traditional methods of collecting data cables often involve manually winding and stacking them, which consumes considerable time and labor. Furthermore, manual winding results in messy and tangled cables, leading to knots during subsequent use. Long-term improper storage also damages the sensors and data cables of the three-dimensional earth pressure cells, ultimately reducing measurement accuracy.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a protective and storage device for a three-dimensional earth pressure box, comprising: a three-dimensional earth pressure box, data cables, an outer protective shell, a handle, and a shock-absorbing device. The outer protective shell includes an outer rotating shaft and an inner fixed shaft. The upper and lower ends of the rotating shaft and the fixed shaft are connected by a rolling wheel mechanism. The upper end of the rotating shaft is connected to an upper rotating disk, and the lower end of the fixed shaft is connected to a lower rotating disk. A positioning slot device is installed inside the fixed shaft, and the lower part passes through the bottom of the outer protective shell and connects to the shock-absorbing device. The positioning slot device is adapted to the three-dimensional earth pressure box. A detachable rotating handle is installed on the upper right side of the upper rotating disk. A limit notch is opened on the same side of the upper rotating disk and the outer protective shell. The connecting wire piece is fixed to the lower part of the limit notch of the upper rotating disk. The detachable rotating handle drives the upper rotating disk to rotate, causing the data cables passing through the limit notch to wind around the fixed shaft along with the connecting wire piece.
[0005] The outer periphery of the positioning slot device is a rectangular pad, and an elastic filler is provided between the outer side of the rectangular pad and the inner side of the fixed shaft.
[0006] The rolling wheel assembly mechanism includes an upper sliding wheel assembly and a lower sliding wheel assembly, and the sliding wheel assembly includes rollers and a retainer.
[0007] Preferably, the positioning slot device includes rectangular pads in four directions and elastic filling material. The rectangular pads have a cross-sectional dimension of 76.5mm in length × 18mm in width and a thickness of 2.4mm. The sponge shock-absorbing device includes four shock-absorbing sleeves and four circular pads. The shock-absorbing sleeves have an annular radius of 19.1mm and a filling radius of 0.48mm. The circular pads have a radius of 27.8mm and a thickness of 5.7mm.
[0008] Preferably, the upper rotating disk is a plastic ring with an inner diameter of 54mm, an outer diameter of 130mm, and a height of 103.7mm. The upper rotating disk is connected to a rotating shaft, which is a plastic tube with a radius of 65mm, a height of 103.7mm, and a wall thickness of 2mm. The lower rotating disk is a plastic disc with a radius of 130mm and a height of 14.3mm. The lower rotating disk is connected to a fixed shaft, which is a plastic tube with a radius of 54mm, a height of 103.7mm, and a wall thickness of 2mm.
[0009] Preferably, the limiting notch has a cross-section of 32mm in length × 29.3mm in width and 14.6mm in radius, the dial piece is a plastic sheet with a cross-section of 24mm in length × 18mm in width and 7.5mm in thickness, and the screw-connected detachable rotating handle includes a base and a grip.
[0010] Compared with existing technologies, the advantages of this invention are as follows: This invention can precisely protect the three-dimensional earth pressure box by installing an internal positioning slot device and a shock-absorbing device. The data cable can be collected by rotating the handle. The device connects the rotating shaft and the fixed shaft through a rolling wheel mechanism. While rotating the handle, the rolling wheel mechanism transmits the rotation of the upper rotating disk to the rotating shaft while ensuring the fixed shaft remains stationary. When the upper rotating disk drives the wire guide plate to rotate, it in turn drives the data cable passing through the limiting notch to rotate. This protective and storage device for the three-dimensional earth pressure box is small in size, highly protective, flexible in use, and easy and neat to wind.
[0011] Other advantages, objectives and features of this invention will be apparent in part from the description which follows, and in part from the understanding of those skilled in the art through study and practice of this invention. Attached Figure Description

[0030] The technical solutions of this 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 this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] Please see Figure 5-7 This utility model provides a technical solution: a protective and storage device for a three-dimensional earth pressure box, including a three-dimensional earth pressure box 1, a data cable 2, an outer protective shell 15, a rotating shaft 7, a fixed shaft 5, an upper rotating disk 9, and a lower rotating disk 10. The upper rotating disk 9 has a limiting notch 13 on its right side, with a wire guide plate 14 fixedly connected to the lower right part of the limiting notch 13, and a screw-connected detachable rotating handle 12 on the upper right. The upper end of the rotating shaft 7 is connected to the upper rotating disk 9, and the lower end of the fixed shaft 5 is connected to the lower rotating disk 10. The upper and lower ends of the rotating shaft 7 and the fixed shaft 5 are connected by a rolling wheel mechanism 16. When the detachable rotating handle 12 is rotated, the rolling wheel mechanism transmits the rotation of the upper rotating disk 9 to the rotating shaft 7 while ensuring that the fixed shaft 5 remains stationary. When the upper rotating disk 9 drives the wire guide plate 14 to rotate, it in turn drives the data cable 1 passing through the limiting notch 13 to rotate. This causes the data cable 1 to rotate with the detachable rotating handle 12 and neatly wind around the fixed shaft 5. This can greatly improve the efficiency of wire winding and the standardization of storage for workers in related fields. A lifting handle 12 is fixedly installed at the center of the upper rotating disk 9. The lifting handle 12 makes it convenient for users to carry the device and improves its flexibility.
[0032] Please see Figure 1-2 , Figure 5 The three-dimensional earth pressure box 1 is placed into the fixed shaft 5 using the positioning slot device 3. The positioning slot device 3 consists of four rectangular pads 31 with a cross-section of 76.5mm long × 18mm wide and a thickness of 2.4mm, positioned at the four horizontal endpoints of the three-dimensional earth pressure box 1, and filled with elastic filling material 32. As the three-dimensional earth pressure box 1 is placed, the filling material is compressed, providing a reverse compressive force, which greatly enhances the stability of the three-dimensional earth pressure box 1 and the fixed shaft 5. Furthermore, a shock-absorbing device 4 is installed inside the fixed shaft 5. The shock-absorbing device 4 includes four shock-absorbing sleeves 41 and four circular pads 42. The circular shock-absorbing sleeves 41 have an annular radius of 19.1mm and a filling radius of 0.48mm, while the circular pads 42 have a radius of 27.8mm and a thickness of 5.7mm. Precisely wrapping the three-dimensional earth pressure box 1 with the fixed shaft 5 using the positions of the four sensors below as positioning points greatly enhances the enclosure of the three-dimensional earth pressure box 1 and improves the protection of the three-dimensional earth pressure box 1.
[0033] Please see Figure 3-5 The device uses an upper rotating disk 9, which is a plastic ring with an inner diameter of 54mm, an outer diameter of 130mm, and a height of 103.7mm. A rotating shaft 7 is welded to the upper rotating disk 9. The rotating shaft 7 is a plastic tube with a radius of 65mm, a height of 103.7mm, and a wall thickness of 2mm. The lower rotating disk 10 is a plastic disc with a radius of 130mm and a height of 14.3mm. A fixed shaft 5 is welded to the lower rotating disk 10. The fixed shaft 5 is a plastic tube with a radius of 54mm, a height of 103.7mm, and a wall thickness of 2mm. The size design of the rotating disk 9 significantly reduces the overall size of the device, improving its portability. The size design of the rotating shaft 7 allows the device to accommodate longer data cables 2, improving its compatibility.
[0034] Please see Figure 8 The rolling wheel mechanism 16 of this device includes an upper sliding wheel group 8 and a lower sliding wheel group 6. The sliding wheel group includes rollers 161 and a retainer 162. The fixed shaft 5 and the rotating shaft 7 are directly connected through rollers 161 and retainer 162 to ensure that the fixed shaft 5 and the rotating shaft 7 will not detach. By rotating the rotating handle 12, the rotation of the upper rotating disk 9 is transmitted to the rotating shaft 7 while keeping the fixed shaft 5 stationary. When the upper rotating disk 9 drives the wire guide 14 to rotate, it in turn drives the data cable 1 passing through the limiting notch 13 to rotate. Thus, the data cable 1 rotates with the rotating handle 12 and is neatly wound around the rotating shaft 7. The combined action of the sliding wheel groups 6 and 8 reduces the resistance to the rotation of the device and improves the winding efficiency of the device.
[0035] Please see Figure 8-9 The device features a limiting notch 13 on the right side of the upper rotating disk 9. The limiting notch 13 is a combined shape with a cross-section of 32mm in length and 29.3mm in width, and a radius of 14.6mm. A wire guide 14 is fixedly connected to the lower right part of the limiting notch 13. The wire guide 14 has a cross-section of 24mm in length and 18mm in width, and a thickness of 7.5mm. The limiting notch 13 and the wire guide 14 facilitate the insertion of the data cable 1 into the device, increasing its ease of use. A detachable rotating handle 12 is screw-connected to the upper right part of the limiting notch 13. The base 121 and the handle 122 are connected by screws and can be freely disassembled.
[0036] One specific application of this embodiment: When using the device, the operator first places the three-dimensional earth pressure box 1 into the fixed shaft 5 according to the positioning slot device 3, inserts the data cable 2 into the limiting notch 13, and screws the handle 122 and the base 121 together to form a rotating handle 12. Then, by hand, the operator rotates the rotating handle 12 to transmit the rotation of the upper rotating disk 9 to the rotating shaft 7 while ensuring that the fixed shaft 5 remains stationary. When the upper rotating disk 9 drives the wire guide 14 to rotate, it in turn drives the data cable 1 passing through the limiting notch 13 to rotate. This causes the data cable 1 to rotate with the rotating handle 12 and be neatly wound around the rotating shaft 7, avoiding the phenomenon of the data cable 2 becoming tangled when winding. This effectively protects and stores the three-dimensional earth pressure box.
