Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, and in particular to a hoisting and positioning device for underground drainage pipes. Background Technology

[0002] In the construction of water supply and drainage systems in underground buildings, drainage pipes need to be suspended and fixed below the floor slabs or beams on the top of the building using hoisting equipment. The stability and installation accuracy of this hoisting equipment are directly related to the operational safety and drainage efficiency of the entire drainage system. The conventional construction method is to use expansion bolts to fix the hoisting plate to the top wall, and then use the hanging rods and pipe clamps below to fix the drainage pipes.

[0003] However, there are significant defects in actual installation operations. Due to the dim lighting and limited working space in the underground construction environment, installers find it difficult to accurately judge whether the suspended plate is level with the naked eye when fixing it. This often results in the suspended plate being tilted after installation. This not only makes it difficult to align the drainage pipe interfaces that are subsequently connected, but also causes uneven stress on the various support points of the pipe. Long-term use can easily lead to pipe deformation or joint leakage.

[0004] Furthermore, existing hoisting devices often use rigid contact when fixing pipes, and the locking structure is relatively simple. When high-speed water flows through the drainage pipe or water hammer occurs, the pipe will vibrate significantly. This continuous vibration will not only cause the rigid pipe clamps to wear down the outer wall of the pipe, but also make it easier for the locking nuts, which lack anti-loosening design, to gradually loosen. This will cause the pipe to lose effective restraint and shift or fall, seriously affecting the safety of the underground drainage system.

[0005] Therefore, this utility model proposes an underground drainage pipe hoisting and positioning device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the underground drainage pipe hoisting and positioning device, such as the lack of intuitive horizontal reference leading to easy tilting of the hoisting plate and thus affecting the pipe connection accuracy, and the simple bolt locking structure being prone to loosening under the impact and vibration of water flow and lacking protection for the outer wall of the pipe, this utility model aims to provide an underground drainage pipe hoisting and positioning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an underground drainage pipe hoisting and positioning device, including a hoisting plate, a leveling mechanism disposed at the bottom of the outer wall of the hoisting plate, and a positioning and shock absorption mechanism disposed at the bottom of the hoisting plate.

[0008] The leveling mechanism consists of two threaded holes at the bottom corner of the outer wall of the hanging plate, two screws threaded into the two threaded holes, a mounting groove at the bottom of the outer wall of the hanging plate, and a bubble meter fixedly connected to the inner wall of the mounting groove. The positioning and shock absorption mechanism consists of a fixed plate fixedly connected to the bottom of the outer wall of the hanging plate, a clamping plate fixedly connected to the bottom of the fixed plate, an anti-slip layer fixedly connected to the inner wall of the clamping plate, a threaded hole at the outer wall of the clamping plate, a screw threaded into the one threaded hole, a nut threaded to the end of the screw thread, and anti-slip grooves on one side of the nut.

[0009] Furthermore, the hanging plate is equipped with a leveling mechanism to monitor and adjust its horizontal status during installation, while the positioning and shock absorption mechanism is connected to the hanging plate via a fixing plate and extends downwards to securely clamp the underground pipeline using clamping plates and anti-slip layers.

[0010] Preferably, there are two fixing plates, which are symmetrically distributed on the left and right sides of the bottom of the outer wall of the hanging plate, and the two clamping plates are positioned opposite each other, thus forming a stable double-arm support structure.

[0011] Preferably, the clamping plate has a semi-circular arc structure, the inner diameter of the clamping plate is adapted to the outer diameter of the underground pipeline, and the anti-slip layer is tightly attached to the outer wall of the underground pipeline to ensure that the contact area of ​​the clamp is maximized.

[0012] Preferably, the anti-slip layer is a flexible pad made of rubber material, which is glued and fixed to the inner arc surface of the clamping plate, and the surface of the anti-slip layer is provided with several anti-slip grooves to increase frictional resistance and absorb vibration energy.

[0013] Preferably, threaded holes are respectively opened at the upper and lower ends of the outer wall of the adjacent side of the two clamping plates, and screws pass through the two opposite threaded holes and extend to the outside of the clamping plates to achieve balanced locking at the upper and lower points.

[0014] Preferably, the anti-slip texture is provided on the end face of the nut facing the outer wall of the clamping plate. When the nut is tightened, the anti-slip texture abuts against the outer wall of the clamping plate, preventing the nut from retracting through mechanical engagement.

[0015] Preferably, the mounting groove is located in the center area of ​​the bottom of the outer wall of the hanging plate, with the groove opening facing directly downwards. The bubble meter is embedded inside the mounting groove and does not protrude from the bottom surface of the hanging plate, making it easy to observe from below without taking up extra space.

[0016] Preferably, the number of threaded holes 2 is set to four, and the four threaded holes 2 are located at the four corners of the hanging plate respectively. The screw 2 is an expansion bolt, thereby providing a stable four-point rectangular support positioning.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the installation of underground drainage pipes is tilted due to the lack of intuitive horizontal reference during the hoisting process, thus affecting the pipe connection accuracy. It is achieved by setting an installation groove at the bottom of the hanging plate and building a bubble meter inside, and adjusting it with screws at the bottom corner. This allows for real-time and intuitive monitoring of the horizontal status of the hanging plate, assisting installers in accurately adjusting the screw insertion depth, thereby minimizing manual installation errors and ensuring the horizontal alignment of the pipes.

[0018] 2. This utility model solves the problem in the prior art that ordinary nuts are easy to loosen and the clamping is unstable due to the vibration caused by the impact of water flow in the drainage pipe. It achieves the effect of preventing the nuts from loosening by using the strong mechanical engagement between the anti-slip texture and the outer wall of the clamping plate, and at the same time using the anti-slip layer to buffer the vibration energy, thus achieving double anti-loosening and anti-vibration, and significantly improving the long-term operational stability of the device.

[0019] 3. This utility model solves the problem that hard metal clamps in the prior art are prone to scratching the outer wall of the drainage pipe and causing surface damage when tightening by fixing a flexible anti-slip layer on the inner wall of the clamping plate. It achieves the effect of tightly wrapping and clamping the drainage pipe while avoiding rigid damage by using flexible contact, effectively protecting the integrity of the outer wall of the drainage pipe and extending the service life of the pipe.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. Example

[0023] Please refer to Figures 1 to 4 This utility model provides an underground drainage pipe hoisting and positioning device, which aims to solve the problems in the prior art where the lack of intuitive horizontal reference during hoisting plate installation leads to installation tilt and water flow impact vibration easily causes the pipe clamping structure to loosen.

[0024] Please refer to Figure 1 An underground drainage pipe hoisting and positioning device includes a hoisting plate 1 as the main load-bearing component, a leveling mechanism 3 set at the bottom of the outer wall of the hoisting plate 1, and a positioning and shock absorption mechanism 2 set at the bottom of the hoisting plate 1. The hoisting plate 1 serves as the installation base for the entire device, connecting to the building's top wall and bearing the weight of the underground pipe 4 below. The leveling mechanism 3 is distributed at the corners and the center of the bottom surface of the hoisting plate 1 to form a multi-point positioning and visual horizontal reference system. The positioning and shock absorption mechanism 2 extends vertically downward to form a surrounding clamping of the underground pipe 4 and absorb the vibration energy generated by the water flow impact. Through the integration of the leveling mechanism 3 and the positioning and shock absorption mechanism 2 on the hoisting plate 1, the device can achieve precise leveling during installation and anti-seismic and anti-loosening during long-term use.

[0025] Please refer to Figure 1 and Figure 2The leveling mechanism 3, as the core component ensuring the horizontal accuracy of the hoisting, directly acts on the hoisting plate 1. Specifically, four threaded holes 301 are provided at the bottom corner of the outer wall of the hoisting plate 1 to form stable rectangular support points. The screws 302 are expansion bolts and threaded into the inside of the threaded holes 301. The screws 302, passing through the threaded holes 301, firmly install and position the hoisting plate 1 on the top plane of the underground building. In order to eliminate the tilting error caused by the different screw depths during the tightening process of multiple screws 302, an installation groove 303 is provided in the center area of ​​the bottom of the outer wall of the hoisting plate 1. The groove opening of the installation groove 303 faces directly downwards to facilitate the work of the personnel below. Visually, the bubble meter 304 is embedded and fixedly connected to the inner wall of the mounting groove 303. The bubble meter 304 is located inside the mounting groove 303 and does not protrude from the bottom surface of the hanging plate 1, thus not affecting the installation of subsequent components. Through the real-time level feedback provided by the bubble meter 304, the installer can accurately adjust the screw depth of each screw 302 until the hanging plate 1 reaches a completely horizontal state. On this basis, the positioning and shock absorption mechanism 2 is connected to the hanging plate 1 through the fixing plate 201. The fixing plate 201 is fixedly connected to the bottom of the outer wall of the hanging plate 1. The number of fixing plates 201 is set to two. The two fixing plates 201 are symmetrically distributed on the left and right sides of the bottom of the outer wall of the hanging plate 1 and extend vertically downward, which provides a basic support arm for the subsequent suspension of the underground pipe 4.

[0026] Please refer to Figure 3 The core clamping part of the positioning and shock absorption mechanism 2 is composed of a clamping plate 206 connected to the bottom of the fixed plate 201. The clamping plate 206 has a semi-circular arc structure. The two clamping plates 206 set opposite each other can form a circular clamping space that fits the outer diameter of the underground pipe 4. The inner diameter of the clamping plate 206 matches the outer diameter of the underground pipe 4 to ensure full-area contact. In order to avoid the metal clamping plate 206 directly contacting the underground pipe 4 and causing scratches, and to provide shock absorption function, an anti-slip layer 202 is fixedly connected to the inner arc surface of the clamping plate 206. The anti-slip layer 202 is a flexible pad made of rubber. The anti-slip layer 202 is fixed to the inner wall of the clamping plate 206 by adhesive bonding. The surface of the anti-slip layer 202 is provided with several anti-slip grooves to further increase the friction. The anti-slip layer 202 is tightly attached to the outer wall of the underground pipe 4. It absorbs the vibration energy generated by the water flow impacting the pipe by utilizing the characteristics of the flexible material, and also increases the static friction coefficient between the clamping plate 206 and the underground pipe 4.

[0027] Please refer to Figure 3 and Figure 4The upper and lower ends of the outer walls of the two adjacent clamping plates 206 are respectively provided with threaded holes 203. The same screw 204 is threaded between the two opposing threaded holes 203. The screw 204 passes through the two opposing threaded holes 203 and extends to the outside of the clamping plate 206. A nut 205 is threaded to the end of the screw 204 for locking. In particular, anti-slip texture 207 is provided on the end face of the nut 205 facing the outer wall of the clamping plate 206. When the nut 205 is tightened, the anti-slip texture 207 makes strong contact with the outer wall of the clamping plate 206. This structure uses the mechanical biting force generated by the anti-slip texture 207 to prevent the nut 205 from loosening due to continuous vibration, thus forming a double protection system of inner buffer and outer anti-loosening together with the internal anti-slip layer 202.

[0028] Working principle: In the initial stage of device installation, the staff first lifts the hanging plate 1 to the predetermined ceiling or top wall installation position, and initially fixes the hanging plate 1 by turning the four screws 302 that pass through the threaded hole 301. At this time, the staff observes the position of the bubble meter 304 in the installation groove 303 from below. Based on the direction of the bubble deviating from the center, the staff judges the tilt state of the hanging plate 1, and then adjusts the screw depth of the four screws 302 in a targeted manner until the bubble of the bubble meter 304 is centered, thereby ensuring that the hanging plate 1 is in a completely horizontal state. This process eliminates the tilt of the hoisting reference plane caused by manual installation error or uneven wall surface, and provides a horizontal reference for the subsequent precise connection of the underground pipe 4. After the hanging plate 1 is positioned, the underground pipe 4 is placed between the two clamping plates 206. Since the inner wall of the clamping plate 206 is provided with a flexible anti-slip layer 202, the anti-slip layer 202 is closely attached to the outer wall of the underground pipe 4. On the one hand, the soft material avoids the hard metal from scratching the pipe surface, and on the other hand, it increases the friction to prevent the pipe from sliding. Then, the screw 204 is passed through the threaded hole 203 of the two clamping plates 206 and screwed into the nut 205 for locking. As the nut 205 is tightened, the clamping plate 206 retracts inward to hug the underground pipe 4. At the same time, the anti-slip texture 207 on the end face of the nut 205 is deeply pressed against the outer wall of the clamping plate 206 to form a mechanical engagement. After the device is put into use, when the water flow inside the underground pipe 4 causes vibration, the internal anti-slip layer 202 absorbs and buffers the vibration energy by using the elastic deformation of the rubber material, reducing the transmission of vibration to the hanging plate 1. The external anti-slip texture 207 uses high frictional interlocking force to prevent the nut 205 from loosening due to continuous micro-vibration. This synergistic effect of internal buffering and external locking ensures the stability and safety of an underground drainage pipe hoisting and positioning device in a long-term operating environment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing 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.
