Description

Technical Field

[0001] This utility model relates to the field of buried pipe and cable laying technology, and in particular to a buried pipe and cable laying device for water conservancy projects. Background Technology

[0002] In the construction of buried pipelines in water conservancy projects, the line-laying operation is a crucial step to ensure the accuracy of pipeline placement and compliance with slope requirements. Currently, commonly used line-laying devices mostly rely on tools such as measuring tapes and measuring ropes, along with weights, for positioning. The core principle is to use the gravity of the weight to keep the measuring tape or rope taut, thereby reading and marking parameters such as depth and slope of the buried pipeline path.

[0003] However, in actual outdoor construction environments, such devices have obvious limitations: water conservancy construction sites are mostly in open environments, and wind interference is common. The weight of the counterweight of the existing device is fixed. When the wind force reaches a certain level, the counterweight is easily impacted by the airflow and shakes, causing the measuring tape to be unable to maintain a vertical and taut state, thus causing measurement errors.

[0004] Therefore, in order to address the problem of insufficient measurement accuracy caused by wind interference in the laying of pipes in water conservancy projects, there is an urgent need for a laying device with adjustable counterweight. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for laying pipes and cables in water conservancy projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water conservancy engineering pipe laying device, comprising a measuring housing, a rotating disk fixedly connected to one side of the outer wall of the measuring housing in the horizontal direction, a measuring tape roller fixedly connected to the output end of the rotating disk in the horizontal axis, a measuring tape wrapped around the outer circumference of the measuring tape roller, one end of the measuring tape being fixedly connected to the end of the measuring tape roller, the end of the measuring tape away from the measuring tape roller penetrating the bottom of the measuring housing in the vertical direction and extending to the outside, and a main counterweight being fixedly connected to this end, a connecting device being detachably connected to the bottom of the main counterweight, and a storage device being fixedly provided on the top of the measuring housing.

[0007] Preferably, the connecting device includes a secondary counterweight block, the top of which is integrally formed with a rectangular connecting block, and the bottom of the main counterweight block having a rectangular slot adapted to the rectangular connecting block in the vertical direction. The rectangular connecting block is slidably inserted into the rectangular slot in the vertical direction. A locking groove is formed on one side of the inner wall of the rectangular slot in the horizontal direction, and a sliding channel is formed on the corresponding side of the rectangular connecting block in the horizontal direction. A wedge-shaped locking block is slidably disposed in the sliding channel, and one end of the wedge-shaped locking block can slide into the locking groove in the horizontal direction. A first telescopic column is fixedly connected to the inner wall of the sliding channel away from the locking groove. The telescopic end of the first telescopic column is fixedly connected to the side of the wedge-shaped locking block away from the locking groove. A first elastic element is sleeved on the outer periphery of the first telescopic column. One end of the first elastic element is fixedly connected to the inner wall of the sliding channel, and the other end is fixedly connected to the wedge-shaped locking block. Hook rings are symmetrically fixed on both sides of the measuring housing, and an adjustable shoulder strap is attached between the two hook rings.

[0008] Preferably, the locking groove has a constraint cavity formed vertically on the top inner wall near the rectangular slot, and a pushing plate is slidably disposed vertically in the constraint cavity, the bottom of the pushing plate abutting against the top of the wedge-shaped locking block.

[0009] Preferably, a U-shaped operating plate is slidably disposed in the constraint groove along the vertical direction, the bottom of the U-shaped operating plate is fixedly connected to the top of the pushing plate, and both ends of the U-shaped operating plate extend to the outside of the main counterweight block.

[0010] Preferably, a second telescopic column is fixedly connected to the top inner wall of the constraint groove cavity. The telescopic end of the second telescopic column extends downward in the vertical direction and is fixedly connected to the top of the C-shaped operating plate. A second elastic element is sleeved on the outer periphery of the second telescopic column. One end of the second elastic element is fixedly connected to the top inner wall of the constraint groove cavity, and the other end is fixedly connected to the top of the C-shaped operating plate. In its natural state, the second elastic element pulls the C-shaped operating plate upward to reset.

[0011] Preferably, the storage device includes a storage frame fixed horizontally to the top of the measuring housing, the storage frame having an opening on one side and a sliding support plate slidably disposed on its inner wall in the horizontal direction; a fixing groove is provided on the side of the measuring housing near the opening of the storage frame.

[0012] Preferably, the top of the sliding support plate has a recessed groove along its length, and a rotating shaft is fixedly connected between the inner walls of the two ends of the recessed groove. A limiting strip is rotatably sleeved on the outer periphery of the rotating shaft, and the limiting strip can be flipped around the rotating shaft to a vertical state; a cushioning cotton strip is fixedly attached to the bottom of the limiting strip.

[0013] Preferably, the bottom surface of the cushioning cotton strip is integrally formed with multiple evenly distributed anti-slip protrusions. When the limiting strip is flipped to a horizontal state, the cushioning cotton strip can abut against the surface of the counterweight placed on the sliding tray to achieve compression limiting.

[0014] Preferably, the surface of the limiting strip is provided with locking holes along the length direction, and an elastic card is fixedly connected to the surface of the measuring housing near the storage frame.

[0015] Beneficial effects

[0016] 1. This utility model achieves flexible adjustment of the counterweight by setting up detachable main and secondary counterweight blocks and connecting devices. When the outdoor wind force is strong, the secondary counterweight block can be quickly installed through the cooperation of rectangular connecting blocks and rectangular slots. The wedge-shaped locking block and locking groove locking structure ensures a stable connection, significantly increasing the overall counterweight, effectively offsetting the impact of wind on the measuring tape, preventing the measuring tape from shaking, and ensuring that the measuring tape remains vertical and taut during the laying process, thus improving the accuracy of the buried pipe path measurement.

[0017] 2. The design of the connecting device allows the counterweight to be flexibly disassembled and assembled according to the actual conditions such as wind force and terrain on site. When the wind force is small, the main counterweight can be used alone to reduce the operating burden; when the wind force is large, the auxiliary counterweight is added to improve the wind resistance and meet the needs of different construction environments, making it more adaptable.

[0018] 3. The storage device on the top of the measuring housing is specifically designed for the secondary counterweight. The storage frame and sliding tray work together to facilitate convenient storage of the secondary counterweight. The sliding tray can be easily pulled out or pushed in. Limiting strips and cushioning strips securely hold the secondary counterweight in place, preventing damage during transport. The snap-fit ​​structure of the elastic clips and locking holes ensures the sliding tray remains securely in place after storage. Combined with hooks and shoulder straps, this makes it easy for operators to carry the entire device, reducing the risk of lost parts and improving efficiency during construction preparation and finishing stages.

[0025] Example 1, as Figure 1-5 As shown in the figure, this embodiment discloses a pipe laying device for water conservancy projects, including a measuring housing 1. The measuring housing 1 is a hollow rectangular structure. A rotating disk 2 is fixed to one outer wall of the measuring housing 1 by bolts. A measuring tape roller 3 is fixedly connected to the output end of the rotating disk 2 by a coupling. The measuring tape roller 3 is horizontally arranged inside the measuring housing 1, and a measuring tape 4 is wound around its outer circumference. The measuring tape 4 is made of fiberglass, which has tensile strength and corrosion resistance. The surface is printed with millimeter-level graduations, and the maximum range is 5-10m. The connection strength between the end and the main counterweight 5 is ≥3kg to prevent detachment. One end of the measuring tape 4 is welded and fixed to the end of the measuring tape roller 3, and the other end extends vertically through a through hole at the bottom of the measuring housing 1 to the outside. The main counterweight 5 is fixedly connected to the main counterweight 5 by screws. The main counterweight 5 is made of cast iron (galvanized for rust prevention), and a connecting device for increasing the counterweight is provided at its bottom. The connecting device includes a secondary counterweight 6, which is made of the same material as the main counterweight 5. A rectangular connecting block 7 is integrally formed on the top of the secondary counterweight 6, and a rectangular slot 8 adapted to the rectangular connecting block 7 is opened vertically at the bottom of the main counterweight 5.

[0026] A horizontally oriented locking groove 9 is formed on one inner wall of the rectangular slot 8, and a horizontally oriented sliding channel 10 is formed on the corresponding side of the rectangular connecting block 7. A wedge-shaped locking block 12 is slidably disposed within the sliding channel 10. The wedge-shaped locking block 12 has an inclined surface (30°-45° angle for easy insertion guidance) on one side near the entrance of the rectangular slot 8, and a vertical surface on the other side (to ensure that it does not loosen after being locked). A first telescopic column 13 is welded to the inner wall of the sliding channel 10 away from the locking groove 9. The first telescopic column 13 consists of an inner rod and an outer cylinder. The inner rod is slidably inserted into the outer cylinder, and its telescopic end is welded and fixed to the side of the wedge-shaped locking block 12 away from the locking groove 9.

[0027] A first elastic element 14 is sleeved on the outer periphery of the first telescopic column 13. The first elastic element 14 is a compression spring, one end of which is welded to the inner wall of the sliding channel 10, and the other end is welded to the wedge-shaped locking block 12. The compression amount is 5-10mm, ensuring that the wedge-shaped locking block 12 can be fully engaged in the locking groove 9. When the rectangular connecting block 7 is inserted into the rectangular slot 8, the inclined surface of the wedge-shaped locking block 12 is squeezed, causing the first elastic element 14 to compress. After full insertion, the first elastic element 14 resets and pushes the wedge-shaped locking block 12 to slide into the locking groove 9, thereby fixing the main and auxiliary counterweights.

[0028] To facilitate the separation of the main and auxiliary counterweights, a constraint cavity 15 is vertically formed on the inner top wall of the locking groove 9 near the rectangular slot 8. A push plate 16 is slidably disposed vertically within the constraint cavity 15, and the bottom of the push plate 16 can abut against the top of the wedge-shaped locking block 12. A C-shaped operating plate 17 is slidably disposed within the constraint cavity 15, and the bottom of the C-shaped operating plate 17 is welded to the top of the push plate 16. Both ends of the operating plate 17 extend to the outside of the main counterweight 5 for easy finger pressing operation.

[0029] A second telescopic column 18 (with the same structure as the first telescopic column) is welded to the top inner wall of the constraint cavity 15, and its telescopic end is welded to the top of the U-shaped operating plate 17. A second elastic element 19 is sleeved on the outer periphery of the second telescopic column 18. The second elastic element 19 is a tension spring, one end of which is welded to the top inner wall of the constraint cavity 15, and the other end is welded to the top of the U-shaped operating plate 17. In its natural state, the U-shaped operating plate 17 can be pulled upward to reset. When separation is required, the U-shaped operating plate 17 is pressed down, and the pushing plate 16 pushes the wedge-shaped locking block 12 out of the locking groove 9, so that the secondary counterweight block 6 can be pulled out.

[0030] The top of the measuring housing 1 is provided with a storage device for storing the auxiliary counterweight. The storage device includes a storage frame 20 that is fixed to the top of the measuring housing 1 by bolts. The storage frame 20 is a rectangular frame with an opening on one side. A sliding support plate 21 is slidably provided on its inner wall in the horizontal direction. The sliding support plate 21 is made of ABS plastic and can be pulled out or pushed in along the length of the storage frame 20.

[0031] The top of the sliding support plate 21 has a recessed groove 22 along its length. A rotating shaft 23 is welded between the inner walls of the two ends of the recessed groove 22. A limiting strip 24 is rotatably fitted around the outer periphery of the rotating shaft 23. The limiting strip 24 can be rotated around the rotating shaft 23 to a horizontal or vertical position. A cushioning cotton strip 25 is attached to the bottom of the limiting strip 24. The cushioning cotton strip 25 is made of high-density sponge, and its bottom surface is integrally formed with multiple anti-slip protrusions 27 to increase the friction with the counterweight.

[0032] A fixing groove is provided on the side of the measuring housing 1 near the opening of the storage frame 20. A locking hole 26 is provided along the length of the surface of the limiting strip 24. An elastic clip 28 is welded to the surface of the measuring housing 1 near the storage frame 20. The elastic clip 28 is made of 65Mn spring steel and has elastic deformation, with its free end bending downwards. When the sliding tray 21 is fully pushed into the storage frame 20, the limiting strip 24 is flipped to engage with the fixing groove, and the free end of the elastic clip 28 engages with the locking hole 26, thus positioning the sliding tray 21. It can be manually pried off.

[0033] In addition, hook rings 29 are symmetrically welded to both sides of the measuring housing 1, and a nylon shoulder strap 30 is attached between the two hook rings 29. The length can be adjusted by adjusting the buckle to facilitate the operator to carry the device.

[0034] The working process of this embodiment is as follows: During use, the operator carries the device to the detection point via shoulder strap 30, places the measuring housing 1 on the top edge of the foundation and adjusts it to a horizontal state; depending on the outdoor wind conditions (it is recommended to add counterweight when the wind force is ≥3), choose whether to install the auxiliary counterweight block 6. If installation is required, align the rectangular connecting block 7 with the rectangular slot 8 and insert it vertically. The wedge-shaped locking block 12 will automatically lock into the locking groove 9 after being squeezed and contracted, thus completing the fixation; rotate the rotating disk 2 to drive the measuring tape roller 3 to rotate, slowly releasing the measuring tape 4. Under the action of gravity, the main and auxiliary counterweight blocks pull the measuring tape 4 vertically downwards. Once the measuring tape 4 has stabilized after contacting the bottom of the foundation, read the scale at the point where the measuring tape 4 is flush with the bottom of the measuring housing 1; this is the foundation depth. After use, reverse the rotating disk 2 to retrieve the measuring tape 4, press the U-shaped operating plate 17 to disengage the wedge-shaped locking block 12 from the locking groove 9, and separate the main and auxiliary counterweights. Place the auxiliary counterweight 6 on the sliding support plate 21, flip the limiting strip 24 to press the cushioning cotton strip 25 on top of the auxiliary counterweight 6, push in the sliding support plate 21 and flip the limiting strip 24 to lock into the fixing groove. The elastic card 28 is locked into the locking hole 26 to complete the positioning, and the device can then be carried away.

[0035] With the above structure, the counterweight can be flexibly adjusted according to outdoor wind force to ensure that the measuring tape is taut, improve measurement accuracy, and facilitate storage and carrying, making it suitable for use in foundation testing scenarios.
