Description

Technical Field

[0001] This application relates to the field of concrete pouring pump pipe technology, and in particular to a crack-resistant concrete pouring pump pipe system for high-rise buildings. Background Technology

[0002] High-rise buildings typically refer to buildings with a large number of floors and considerable height. During the concrete pouring process for the floor slabs of high-rise buildings, a pumping system is usually required to transport the concrete from the mixer truck to the specific location at a high altitude on the construction site.

[0003] In related technologies, such as Chinese patent document CN207920100U, a crack-resistant concrete pouring pump pipe system for high-rise buildings is disclosed. This system includes a concrete conveying riser connected to a ground pump, a concrete conveying horizontal pipe connected to the upper end of the riser, a second section of the horizontal concrete conveying pipe connected to the other end of the horizontal concrete conveying pipe, a flexible hose connected to the other end of the second section, the flexible hose positioned above the floor slab being poured, a tower crane hoisting rope installed between the horizontal concrete conveying pipe and the second section, a pump pipe coupling clamp installed at the junction of the two sections, a left pump pipe clamp installed on the second section, a right pump pipe clamp installed on the horizontal concrete conveying pipe, and connecting steel bars welded between the left pump pipe clamp, the pump pipe coupling clamp, and the right pump pipe clamp. In use, the tower crane lifts and moves the two sections of the concrete delivery horizontal pipe using hoisting ropes. Concrete enters the concrete delivery horizontal pipe through the ground pump and concrete delivery riser, and then sprays out from the hose. Construction workers hold the hose on the floor slab pouring surface and move it to complete the concrete pouring at different locations.

[0004] Regarding the aforementioned technologies, construction workers may find it difficult to determine the depth of the poured concrete at their location while assisting in moving the hose, which could easily affect the quality of the pouring. Summary of the Invention

[0005] To facilitate construction workers in roughly judging the depth of poured concrete and to ensure the quality of pouring to a certain extent, this application provides a crack-resistant concrete pouring pump pipe system for high-rise buildings.

[0006] The crack-resistant high-rise building concrete pouring pump pipe system provided in this application adopts the following technical solution: A crack-resistant concrete pouring pump pipe system for high-rise buildings includes a flexible hose with an installation ring fitted on it. A probe is slidably mounted on the installation ring, with the sliding direction of the probe parallel to the axis of the installation ring and the length direction of the probe parallel to the axis of the installation ring. The probe has graduations along its length, and the installation ring has a reset element for resetting the probe by sliding it away from the concrete.

[0007] By adopting the above technical solution, the probe rod is slid towards the floor slab surface, gradually moving downwards and extending into the poured concrete. Construction workers can roughly judge the depth of the poured concrete by reading the scale value corresponding to the concrete surface on the probe rod. This method is simple and convenient, helps construction workers control the amount of concrete poured, and ensures the quality of the pouring to a certain extent.

[0008] Preferably, an installation ball is fitted onto the hose, and the installation ring is fitted onto the installation ball.

[0009] By adopting the above technical solution, the mounting ring is connected to the mounting ball, allowing the mounting ring to rotate in any direction. This makes it easier to keep the mounting ring in a horizontal position and the probe rod in a vertical position, which helps to improve the accuracy of the probe rod in detecting the depth of poured concrete.

[0010] Preferably, the mounting ring is provided with a plurality of balance cones, which are evenly spaced along the circumference of the mounting ring. A counterweight is provided on the side of the mounting ring away from the probe rod, and the counterweight is used to balance the weight on both sides of the mounting ring.

[0011] By adopting the above technical solution, the setting of multiple balance cones and counterweights helps to keep the installation ring in a horizontal state, making it less likely to tilt with the hose, thereby ensuring the accuracy of the probe rod in detecting the depth of the poured concrete.

[0012] Preferably, a rotating ring is rotatably sleeved on the mounting ring, the rotation axis of the rotating ring is parallel to the axial direction of the mounting ring, the probe is slidably disposed on the rotating ring, the reset member is disposed on the rotating ring, and the counterweight is disposed on the rotating ring.

[0013] By adopting the above technical solution, the rotating ring drives the detection rod to move, so that the detection rod moves to the side of the hose away from the construction personnel, which helps to make the detection rod less likely to obstruct the normal operation of the construction personnel.

[0014] Preferably, an observation plate is slidably mounted on the detection rod, the sliding direction of the observation plate is parallel to the length direction of the detection rod, and the observation plate is provided with a fixing member for fixing or moving the observation plate relative to the detection rod.

[0015] By adopting the above technical solution, the observation plate is slid into the appropriate position of the probe rod according to the actual required pouring depth. The observation plate and the probe rod are fixed relative to each other by the fixing parts, which makes it convenient for construction personnel to observe whether the poured concrete has reached the observation plate and provides convenience for roughly judging the depth of the concrete.

[0016] Preferably, the fixing member includes a clamping bolt threaded through the observation plate, the rotation axis of the clamping bolt being perpendicular to the length direction of the probe rod, and the clamping bolt being used to clamp or disengage from the probe rod.

[0017] By adopting the above technical solution, the clamping bolt is rotated to make it contact or disengage from the probe rod, thereby facilitating the relative fixation or relative sliding of the observation plate and the probe rod.

[0018] Preferably, the observation plate has an opening, and a detection cloth is provided on the bottom wall of the observation plate, with the detection cloth covering the opening.

[0019] By adopting the above technical solution, when the poured concrete reaches the height of the observation plate, the moisture in the concrete will wet the detection cloth, and water will soak through the detection cloth, further facilitating the judgment of the construction personnel.

[0020] Preferably, a temperature and humidity sensor is provided at the end of the probe near the concrete, and a microcontroller and a micro alarm are provided on the rotating ring. The temperature and humidity sensor is wirelessly connected to the microcontroller, and the microcontroller is electrically connected to the micro alarm.

[0021] By adopting the above technical solution, the temperature and humidity sensor detects the temperature and humidity of the poured concrete and sends it to the micro controller. The micro controller compares the received temperature and humidity with the preset range. When the temperature and humidity do not meet the preset range, the micro controller causes the micro alarm to sound, which makes it easier for construction personnel to know in time during seasonal construction that the temperature and humidity of the concrete do not meet the construction requirements, which helps to ensure construction quality and reduce the possibility of concrete cracking later.

[0022] Preferably, the reset component includes a reset spring for resetting the probe rod by sliding it away from the concrete. One end of the reset spring is disposed on the probe rod, and the other end is disposed on the rotating ring.

[0023] Preferably, the crack-resistant high-rise building concrete pouring pump pipe system also includes a concrete delivery horizontal pipe assembly. The flexible hose is connected to the concrete delivery horizontal pipe assembly, and the concrete delivery horizontal pipe assembly is equipped with a pressure sensor, a flow sensor, and a concentration sensor. The pressure sensor, flow sensor, and concentration sensor are all wirelessly connected to an external control platform.

[0024] In summary, this application includes the following beneficial technical effects: Slide the probe towards the floor slab surface to gradually lower it into the poured concrete. Construction workers can roughly judge the depth of the poured concrete by reading the scale value corresponding to the concrete surface on the probe. This is simple and convenient, and helps construction workers control the amount of concrete poured, thus ensuring the quality of the pouring to a certain extent. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a crack-resistant concrete pouring pump pipe system for high-rise buildings. (Refer to...) Figure 1 The crack-resistant concrete pouring pump pipe system for high-rise buildings includes a ground pump, a concrete delivery riser assembly, a concrete delivery horizontal pipe assembly, and a hose 1. The concrete delivery horizontal pipe assembly has the same structure as the multi-section concrete delivery horizontal pipe in related technologies, which helps to prevent pipe cracking.

[0031] Reference Figure 1 and Figure 2 A mounting ball 5 is fitted onto the flexible hose 1. The mounting ball 5 is located at the end of the flexible hose 1 furthest from the horizontal concrete conveying pipe assembly, and the distance from the center of the mounting ball 5 to the end of the flexible hose 1 furthest from the horizontal concrete conveying pipe assembly is 10cm. By designing the mounting ball 5 to be lower than the position where the construction worker holds the flexible hose 1, it is less likely to affect the construction worker's operation of pushing the flexible hose 1. A mounting ring 2 is fitted onto the mounting ball 5, and a rotating ring 8 is fitted over the mounting ring 2. The rotating ring 8 is coaxial with the mounting ring 2.

[0032] Reference Figure 2A support rod 17 is fixed to the upper surface of the rotating ring 8. The length direction of the support rod 17 is parallel to the axis of the mounting ring 2. A connecting plate 18 is slidably sleeved on the support rod 17. The connecting plate 18 is located above the rotating ring 8. The sliding direction of the connecting plate 18 is parallel to the axis of the mounting ring 2. A limit ring 19 is fixed to the top of the support rod 17 to prevent the connecting plate 18 from detaching from the support rod 17. A probe rod 3 is fixed to the side of the connecting plate 18 near the rotating ring 8. The length direction of the probe rod 3 is parallel to the axis of the mounting ring 2. The probe rod 3 is located outside the rotating ring 8. The lower end of the probe rod 3 is an arc surface that bulges outward in the direction away from the connecting plate 18. The probe rod 3 is slidably connected to the rotating ring 8 through the connecting plate 18. The sliding connection between the connecting plate 18 and the support rod 17 guides the sliding of the probe rod 3. The probe rod 3 is marked with a scale 4 along its own length direction. A reset component is provided on the rotating ring 8 to reset the probe rod 3 by sliding it away from the concrete.

[0033] During use, construction workers guide the flexible hose 1 to move it during pouring, pressing the connecting plate 18 towards the floor slab surface. The connecting plate 18 moves the probe rod 3 downwards, gradually inserting its lower end into the poured concrete until it contacts the floor slab surface. By reading the corresponding scale 4 on the concrete surface of the probe rod 3, the depth of the poured concrete can be roughly determined. This simple and convenient method helps construction workers control the amount of concrete poured, ensuring pouring quality to a certain extent. After use, the connecting plate 18 is released, and the reset mechanism moves the connecting plate 18 and probe rod 3 upwards to reset them, reducing the impact of the probe rod 3 on subsequent pouring movements.

[0034] When the probe rod 3 moves down and comes into contact with the reinforcing bar, the connecting plate 18 causes the probe rod 3 to rotate along the support rod 17 at a certain angle, so that the probe rod 3 is misaligned with the reinforcing bar, thus making it easier to roughly judge the depth of the poured concrete.

[0035] Reference Figure 2 To facilitate the sliding of the probe rod 3 away from the concrete for resetting, the resetting component includes a resetting spring 16. The resetting spring 16 is movably sleeved on the support rod 17. The extension direction of the resetting spring 16 is parallel to the sliding direction of the probe rod 3. One end of the resetting spring 16 is fixed to the lower surface of the connecting plate 18, and the other end is fixed to the upper surface of the rotating ring 8. When the resetting spring 16 is in its natural state, the lower end of the probe rod 3 is flush with the port of the hose 1.

[0036] As the probe rod 3 slides towards the concrete and gradually extends into the poured concrete, the connecting plate 18 moves downward, compressing the return spring 16. After the concrete depth is detected, the connecting plate 18 is released. The compressed return spring 16, with its elastic force, pushes the connecting plate 18, causing the probe rod 3 to slide away from the concrete and reset, thereby reducing the impact of the probe rod 3 on the subsequent movement of the hose 1.

[0037] Reference Figure 2 and Figure 3 An observation plate 9 is slidably mounted on the probe rod 3. The sliding direction of the observation plate 9 is parallel to the length direction of the probe rod 3. The observation plate 9 is provided with a fixing component for fixing the observation plate 9 relative to the probe rod 3. The fixing component includes a clamping bolt 10, which is threaded onto the observation plate 9. The rotation axis of the clamping bolt 10 is perpendicular to the length direction of the probe rod 3. The clamping bolt 10 is located on the side of the observation plate 9 near the rotating ring 8. The clamping bolt 10 is used to abut against or disengage from the outer wall of the probe rod 3. In other embodiments, the clamping bolt 10 can be replaced with a screw, pin, etc. Connecting grooves for connecting and engaging with screws or pins are spaced along the length direction of the probe rod 3. Through the engagement of the screws or pins with the connecting grooves, the relative fixation or relative movement of the probe rod 3 and the observation plate 9 can usually be achieved.

[0038] During construction, rotate the clamping bolt 10 to disengage it from the probe rod 3. Then, move the observation plate 9 until its lower edge reaches the mark 4, indicating the required pouring depth. Next, rotate the clamping bolt 10 again to engage it with the probe rod 3, thus fixing the observation plate 9 and probe rod 3 in place. When the sliding probe rod 3 is inserted into the poured concrete to determine the depth, observing whether the poured concrete reaches the observation plate 9 provides a convenient way for construction personnel to assess whether the required depth has been achieved.

[0039] Reference Figure 2 and Figure 3 An opening 11 is provided on the side of the observation plate 9 away from the tightening bolt 10. The opening 11 penetrates the side of the observation plate 9 away from the tightening bolt 10. A detection cloth 12 is fixed on the bottom wall of the observation plate 9. The detection cloth 12 is a filter cloth. The detection cloth 12 covers the opening 11. The lower surface of the detection cloth 12 is 1 mm lower than the lower surface of the observation plate 9.

[0040] When the poured concrete reaches the height of the observation plate 9, the moisture in the concrete will wet the detection cloth 12, and water will soak through the detection cloth 12, which will further facilitate the judgment of the construction personnel. At the same time, the detection cloth 12 can be reused many times and is not easily damaged.

[0041] Reference Figure 2 The rotating ring 8 is rotatably mounted on the mounting ring 2, and the axis of rotation of the rotating ring 8 is parallel to the axis of the mounting ring 2. By rotating the rotating ring 8, it can be adjusted according to the position of the construction worker while the worker is moving the hose 1, causing the rotating ring 8 to move the detection rod 3 to the side of the hose 1 away from the worker, thus minimizing interference with the worker's operation.

[0042] Reference Figure 2 The mounting ring 2 is ball-jointed onto the mounting ball 5. Multiple balance cones 6 are evenly spaced along the circumference of the bottom wall of the mounting ring 2. The balance cones 6 are suspended from the bottom wall of the mounting ring 2 by a suspension line 20. In this embodiment, four balance cones 6 are evenly distributed along the circumference of the mounting ring 2; in other embodiments, the number of balance cones 6 can be set according to actual needs. A counterweight 7 is fixed to the upper surface of the rotating ring 8 on the side away from the probe rod 3. The counterweight 7 is used to maintain weight balance on opposite sides of the mounting ring 2. The weight of the counterweight 7 is compatible with the weights of the support rod 17, connecting plate 18, limiting ring 19, probe rod 3, and observation plate 9 on the rotating ring 8.

[0043] During the long-term pushing process, the hose 1 is prone to tilting, while the mounting ring 2, under the action of the four balance cones 6, can maintain a horizontal state as much as possible, so that the probe rod 3 can remain as vertical as possible, thereby improving the accuracy of the probe rod 3 in detecting the depth of the poured concrete.

[0044] Reference Figure 2 A temperature and humidity sensor 13 is embedded in the side wall of the lower end of the detection rod 3. A micro controller 14 and a micro alarm 15 are installed on the upper surface of the rotating ring 8. The micro controller 14 and the micro alarm 15 are symmetrically arranged along the hose 1, and the arrangement direction of the micro controller 14 and the micro alarm 15 is perpendicular to the arrangement direction of the counterweight 7 and the support rod 17, which helps to maintain the balance of the mounting ring 2. The temperature and humidity sensor 13 is wirelessly connected to the micro controller 14, and the micro controller 14 and the micro alarm 15 are electrically connected.

[0045] When the probe 3 is inserted into the poured concrete, the temperature and humidity sensor 13 detects the temperature and humidity of the poured concrete and sends it to the microcontroller 14. The microcontroller 14 compares the received temperature and humidity with a preset range. When the temperature and humidity exceed the preset range, the microcontroller 14 causes the micro alarm 15 to sound an alarm. The preset range can be set according to construction requirements. This allows construction personnel to promptly know if the temperature and humidity of the concrete do not meet the construction requirements during seasonal construction of high-rise buildings, which helps to ensure construction quality and reduce the possibility of later cracking of the concrete.

[0046] Reference Figure 1A pressure sensor 21, a flow sensor 22, and a concentration sensor 23 are fixedly installed on any section of the horizontal concrete conveying pipe assembly. All three sensors are wirelessly connected to an external control platform. The pressure sensor 21 monitors the concrete pressure in the horizontal pipe in real time and transmits the data to the external control platform. The flow sensor 22 monitors the concrete flow velocity in the pipe in real time and sends the data to the external control platform. The concentration sensor 23 monitors the content and concentration of solid particles in the concrete slurry in real time and sends the data to the external control platform. This allows operators to easily assess the pumping pressure, flow rate, and slurry quality within the pump pipe via the external control platform, enabling intelligent control as needed.

[0047] The implementation principle of this application embodiment is as follows: When in use, rotate the clamping bolt 10 to disengage the clamping bolt 10 from the probe rod 3, then move the observation plate 9 so that the lower edge of the observation plate 9 moves to the depth of the actual pouring required at the scale 4, and then rotate the clamping bolt 10 to clamp the clamping bolt 10 against the probe rod 3, thereby fixing the observation plate 9 and the probe rod 3 relative to each other.

[0048] During construction, workers push the flexible hose 1 to move and pour concrete. When it is difficult to determine whether the depth of the poured concrete meets the requirements, one hand holds the rotating ring 8, and the other hand presses the connecting plate 18 towards the floor slab surface. The connecting plate 18 moves the probe rod 3 and the observation plate 9 on the probe rod 3 downward. The lower end of the probe rod 3 gradually extends into the poured concrete until it touches the floor slab surface. At this time, the probe cloth 12 is observed. If the water in the poured concrete wets the probe cloth 12 or the water soaks through the probe cloth 12, it proves that the depth of the poured concrete meets the requirements, and the position can be changed to continue pouring. If the poured concrete is far below the probe cloth 12, it proves that the poured concrete is insufficient, and it is necessary to continue pouring at this point. This makes it easy for construction workers to roughly judge the depth of the poured concrete. It is simple and convenient, helps construction workers control the amount of concrete poured, and ensures the quality of pouring to a certain extent.

[0049] When the probe 3 is inserted into the poured concrete, the temperature and humidity sensor 13 can also detect the temperature and humidity inside the concrete, so that construction personnel can be aware of any abnormalities in the temperature and humidity of the concrete in a timely manner, thereby reducing the possibility of cracking in the concrete later.

[0050] After use, loosen the connecting plate 18. The compressed return spring 16 will cause the connecting plate 18 and the probe rod 3 to move upward to reset, reducing the influence of the probe rod 3 on the subsequent movement of the hose 1.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
