Description

Technical Field

[0001] This invention belongs to the field of pump pipe joint technology, and in particular relates to a pump pipe joint rotating device and its usage method. Background Technology

[0002] With the development of modern society, land resources are becoming increasingly scarce, while high-rise buildings are becoming more and more common. To facilitate access for personnel, high-rise buildings primarily utilize elevators for vertical transportation, resulting in roof structures with distinct levels—the main building roof, elevator shaft roofs, and machine room roofs—creating working surfaces with varying elevations. In the concrete pouring process for high-rise building roof projects, ground pumps are frequently used.

[0003] Because of the different heights of the roof structure, the concrete pouring process requires pouring at one elevation first. After completion, the pump pipes must be removed and moved to another elevation, and the pipes must be re-laid and connected before the pouring work can continue. However, this process takes a long time. By the time the re-laid pipes are installed, the concrete slurry adhering to the inner wall of the pipes has already begun to set, increasing the friction on the inner wall of the pump pipes. If the concrete pouring work continues, it will lead to blockage of the pump pipes or even pipe bursts.

[0004] Therefore, there is currently a lack of a pump pipe joint rotation device and its usage method that can adjust the upper pump pipe on the roof structure and the lower pump pipe running through the elevator shaft by rotating the component, so that the upper pump pipe can be adjusted from the horizontal direction to the vertical direction, which can adapt to the concrete pouring construction of different elevation working surfaces on the roof of high-rise buildings and improve the efficiency of concrete pouring construction.

[0013] Meanwhile, the present invention also discloses a method for using a reasonably designed pump pipe joint rotation device, characterized in that the method includes the following steps:

[0014] Step 1: Assembly of the adjustable pump pipe section:

[0015] Step 101: Install a rotating component between one end of the first pump pipe section and one end of the second pump pipe section; wherein, a first connecting flange is provided at the other end of the first pump pipe section away from the second pump pipe section.

[0016] Step 102: Install a rotating component between the other end of the second pump pipe section and one end of the third pump pipe section;

[0017] Step 103: Install a rotating component between the other end of the third pump pipe section and one end of the fourth pump pipe section to form an adjustable pump pipe section; wherein, the other end of the fourth pump pipe section away from the third pump pipe section is provided with a second connecting flange;

[0018] Step 2: Connecting the adjustable pump pipe section:

[0019] Step 201: Connect the first connecting flange in the first adjustable pump pipe section to the inlet flange of the upper pump pipe, and connect the second connecting flange in the first adjustable pump pipe section to the outlet flange of the lower pump pipe; wherein the lower pump pipe and the upper pump pipe are arranged vertically.

[0020] Step 202: Connect the second connecting flange in the second adjustable pump pipe section to the outlet flange of the upper pump pipe through the middle slewing bearing, and connect the first connecting flange in the second adjustable pump pipe section to the inlet flange of the outlet pump pipe section.

[0021] Step 203: Move the outlet pump pipe section to the elevation of the main building roof to be poured; wherein, the lower pump pipe passes through the elevator shaft, and the inlet of the lower pump pipe extending out of the elevator shaft is connected to the concrete pump.

[0022] Step 3: Concrete pouring for the main building roof:

[0023] The concrete pump is operated to deliver concrete through the lower pump pipe, the first adjustable pump pipe section, the upper pump pipe, the second adjustable pump pipe section, and the outlet pump pipe section to the pouring elevation of the main building roof, thereby realizing the concrete pouring of the main building roof.

[0024] Step 4: Adjustment of the adjustable pump pipe section by rotation:

[0025] Step 401: Stop the concrete pump and rotate the other end of the third pump pipe section relative to the fourth pump pipe section in the first adjustable pump pipe section, rotate the other end of the second pump pipe section relative to the third pump pipe section, and rotate the first pump pipe section relative to the second pump pipe section, so that the center line of the first connecting flange and the center line of the second connecting flange are at 90°; wherein, the upper pump pipe is laid vertically along the stairwell wall, and the lower pump pipe is laid parallel to the center line of the upper pump pipe;

[0026] Step 402: Operate the second connecting flange in the second adjustable pump pipe section to rotate relative to the outlet flange of the upper pump pipe through the middle slewing bearing, so that the outlet pump pipe section rotates to the roof of the stairwell.

[0027] Step 403: Adjust the length of the outlet pump pipe section so that the outlet of the outlet pump pipe section meets the required pouring elevation of the elevator shaft roof.

[0028] Step 5: Concrete pouring for the elevator shaft roof and machine room roof:

[0029] Step 501: Operate the concrete pump. The concrete pump will transport the concrete through the lower pump pipe, the first adjustable pump pipe section, the upper pump pipe, the second adjustable pump pipe section and the outlet pump pipe section to the elevation to be poured on the roof of the elevator shaft, so as to realize the concrete pouring on the roof of the elevator shaft.

[0030] Step 502: Adjust the length of the outlet pump pipe section so that the outlet of the upper pump pipe meets the required elevation of the machine house roof to be poured, and operate the concrete pump to deliver the lower pump pipe, the first adjustable pump pipe section, the upper pump pipe, the second adjustable pump pipe section and the outlet pump pipe section to the required elevation of the machine house roof to be poured, so as to realize the concrete pouring at the machine house roof.

[0031] The above-described method of use is characterized in that: the rotating component at one end of the first pump pipe section and one end of the second pump pipe section is referred to as the first rotating component; the rotating component between the other end of the second pump pipe section and one end of the third pump pipe section is referred to as the second rotating component; and the rotating component installed between the other end of the third pump pipe section and one end of the fourth pump pipe section is referred to as the third rotating component.

[0032] The other end of the third pump pipe section is rotated relative to one end of the fourth pump pipe section via the third rotating component, and the other end of the second pump pipe section is rotated relative to one end of the third pump pipe section via the second rotating component. The method for rotating one end of the first pump pipe section relative to one end of the second pump pipe section via the first rotating component is the same. The specific process is as follows:

[0033] Rotate the nut, and the spring extends along the connecting rod until it is in a free state. Continue to rotate the nut, and ensure that the nut always fits against the extended end of the spring. This reduces the length of the connecting rod extending out of the annulus. The connecting rod then drives the rotary support to move away from the annulus, so that there is a gap between the sealing ring and the annulus.

[0034] Then the inner ring rotates relative to the outer ring, or the outer ring rotates relative to the inner ring;

[0035] Next, rotate the nut in the opposite direction to increase the length of the connecting rod extending out of the ring. The connecting rod then drives the rotary support to move closer to the ring, so that the sealing ring is tightly sealed against the ring. Continue rotating the nut in the opposite direction, and the nut will compress the spring until the spring is at its maximum extension.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. The present invention has a simple structure, reasonable design, and is easy to install and deploy.

[0038] 2. The present invention is provided with a slewing bearing. The inner ring of the slewing bearing is connected to the first annular seat of one pump pipe section, and the outer ring of the slewing bearing is connected to the second annular seat of another pump pipe section, so that the inner ring rotates relative to the outer ring, or the outer ring rotates relative to the inner ring, thereby realizing the adjustment of the angle between two adjacent pump pipe sections.

[0039] 3. The present invention provides a limiting tooth ring for the rotating support to engage, thereby limiting the rotation of the rotating support and facilitating the rotating support to move closer to or further away from the second annular seat along the axial direction of the limiting tooth ring.

[0040] 4. The present invention provides an adjusting connecting component for two purposes. First, it moves the rotary support away from the second annular seat along the axial direction of the limiting tooth ring, so that there is a gap between the sealing ring on the rotary support and the annular part, which facilitates rotational adjustment. Second, it moves the rotary support closer to the second annular seat along the axial direction of the limiting tooth ring, so that the sealing ring on the rotary support is tightly attached to the annular part, preventing concrete from entering and affecting the rotational adjustment.

[0041] 5. The method of using the pump pipe joint rotation device of the present invention is simple, convenient and easy to operate, ensuring that it can be adapted to concrete pouring construction on different elevation working surfaces of high-rise building roofs.

[0042] 6. The pump pipe joint rotation device of the present invention is easy to operate and has good performance. First, the pump pipe section assembly can be adjusted, then the connection of the pump pipe section can be adjusted, and then the main building roof concrete is poured. The adjustable pump pipe section is rotated and adjusted to adapt to the concrete pouring of elevator shaft roof and machine room roof.

[0043] In summary, this invention is reasonably designed and easy to operate. By rotating the components, the upper pump pipe on the roof structure and the lower pump pipe running through the elevator shaft can be adjusted so that the upper pump pipe can be adjusted from the horizontal direction to the vertical direction, which can adapt to the concrete pouring construction of different elevation working surfaces on the roof of high-rise buildings and improve the efficiency of concrete pouring construction.

[0066] like Figures 1 to 4The pump pipe joint rotation device shown includes a rotating component disposed between two adjacent pump pipe sections. The ports connecting the two adjacent pump pipe sections are elliptical openings 10-1 arranged in an inclined parallel pattern. The rotating component includes a first annular seat disposed circumferentially around the elliptical opening 10-1 of one pump pipe section, a rotary support 1-3 disposed on the first annular seat, a second annular seat disposed circumferentially around the elliptical opening 10-1 of the other pump pipe section, and a limiting gear ring 1-6 disposed within the second annular seat and meshing with the rotary support 1-3. An adjusting connecting component is disposed on the second annular seat to adjust the rotary support 1-3 to move axially along the limiting gear ring 1-6.

[0067] In this embodiment, the first annular seat includes a first annular ring 1-2 disposed circumferentially around an elliptical opening 10-1 in a pump pipe section and a second annular ring 1-1 disposed on the first annular ring 1-2 and integrally formed with the first annular ring 1-2. The outer diameter of the first annular ring 1-2 is larger than the outer diameter of the second annular ring 1-1. The central holes of the first annular ring 1-2 and the second annular ring 1-1 are the same as those of the elliptical opening 10-1. The inner ring 1-31 of the rotary support 1-3 is connected to the second annular ring 1-1.

[0068] In this embodiment, the second annular seat includes an annular portion 1-4 disposed circumferentially around the elliptical opening 10-1 of another pump pipe section and a protective limiting ring portion 1-5 disposed circumferentially around the annular portion 1-4 and integrally formed with the annular portion 1-4. The limiting toothed ring 1-6 is mounted on the inner sidewall of the protective limiting ring portion 1-5. The protective limiting ring portion 1-5 extends in the direction close to the first annular seat. The annular portion 1-4, the protective limiting ring portion 1-5 and the limiting toothed ring 1-6 are coaxially arranged. The central hole of the annular portion 1-4 is the same as that of the elliptical opening 10-1.

[0069] In this embodiment, a plurality of mounting holes 1-41 are provided on the annular portion 1-4 along the circumferential direction, and an external gear ring 1-34 is provided on the circumferential side wall of the outer ring 1-32 of the rotary support 1-3. The external gear ring 1-34 is installed in and engaged with the limiting gear ring 1-6.

[0070] The outer ring 1-32 of the slewing support 1-3 is provided with a connecting hole 1-33, and the connecting hole 1-33 corresponds one-to-one with the mounting hole 1-41;

[0071] The adjusting connection component includes a connecting rod 1-35 disposed in the connecting hole 1-33, a spring 1-36 sleeved on the protruding end of the connecting rod 1-35 through the mounting hole 1-41, and a nut 1-37 sleeved on the connecting rod 1-35. One end of the spring 1-36 abuts against the outer wall of the annular portion 1-4, and the other end of the spring 1-36 abuts against the nut 1-37.

[0072] In this embodiment, a sealing ring 1-7 is provided on the side of the inner ring 1-31 of the rotary support 1-3 near the annular portion 1-4. The outer diameter of the sealing ring 1-7 is the same as the outer diameter of the inner ring 1-31, and the inner diameter of the sealing ring 1-7 is the same as the inner diameter of the inner ring 1-31. The sealing ring 1-7 can be arranged to fit against the annular portion 1-4 or to be arranged away from the annular portion 1-4.

[0073] In this embodiment, in actual use, the limiting toothed ring 1-6 is an internal toothed ring, and the outer side wall of the limiting toothed ring 1-6 and the inner side wall of the protective limiting ring 1-5 are fitted together or integrally connected.

[0074] In this embodiment, the protective limiting ring 1-5 and the limiting toothed ring 1-6 have the same axial length.

[0075] In this embodiment, the inner ring 1-31 of the rotary support 1-3 is connected to the first annular seat of a pump pipe section, and the outer ring 1-31 of the rotary support 1-3 is connected to the second annular seat of another pump pipe section, so that the inner ring 1-31 rotates relative to the outer ring 1-32, or the outer ring 1-32 rotates relative to the inner ring 1-31, thereby realizing the adjustment of the angle between two adjacent pump pipe sections.

[0076] In this embodiment, the limiting gear ring 1-6 is provided for the rotary support 1-3 to engage, thereby limiting the rotary support 1-3 and making it easier for the rotary support 1-3 to move closer to or further away from the second annular seat along the axial direction of the limiting gear ring 1-6.

[0077] In this embodiment, the adjustment connecting component is provided for two purposes. First, it is to move the rotary support 1-3 away from the second annular seat along the axial direction of the limiting toothed ring 1-6, so that there is a gap between the sealing ring on the rotary support 1-3 and the annular part 1-4, which facilitates rotational adjustment. Second, it is to move the rotary support 1-3 closer to the second annular seat along the axial direction of the limiting toothed ring 1-6, so that the sealing ring on the rotary support 1-3 is tightly attached to the annular part 1-4, preventing concrete from entering and affecting the rotational adjustment.

[0078] In this embodiment, spring 1-36 is provided so that after the sealing ring 1-7 is tightly sealed against the annular portion 1-4, the nut 1-37 is rotated in the opposite direction. The nut 1-37 then compresses the spring 1-36 until the spring 1-36 is at its maximum extension. In this way, the compressed spring 1-36 prevents the nut 1-37 from loosening during use and ensures that the sealing ring 1-7 is tightly sealed against the annular portion 1-4.

[0079] In this embodiment, a connecting rod 1-35 is provided. On the one hand, the connecting rod 1-35 passes through the ring part 1-4 and, under the action of the spring 1-36 and the nut 1-37, realizes the connection and reinforcement of two adjacent pump pipe sections, adapting to the pressure during concrete conveying; on the other hand, it facilitates subsequent rotation and adjustment, improving the ease of operation.

[0080] In this embodiment, one pump pipe section is such as the first pump pipe section 10, and the other pump pipe section is such as the second pump pipe section 20.

[0081] In this embodiment, the sealing ring 1-7 is only located on the inner ring 1-31, so it does not affect the installation of the connecting rod 1-35 in the connecting hole 1-33 on the outer ring 1-32.

[0082] like Figures 5 to 7 The method of using the pump pipe joint rotating device shown includes the following steps:

[0083] Step 1: Assembly of the adjustable pump pipe section:

[0084] Step 101: Install a rotating component between one end of the first pump pipe section 10 and one end of the second pump pipe section 20; wherein, a first connecting flange 101 is provided at the other end of the first pump pipe section 10 away from the second pump pipe section 20.

[0085] Step 102: Install a rotating component between the other end of the second pump pipe section 20 and one end of the third pump pipe section 30;

[0086] Step 103: Install a rotating component between the other end of the third pump pipe section 30 and one end of the fourth pump pipe section 40 to form an adjustable pump pipe section 7; wherein, the other end of the fourth pump pipe section 40 away from the third pump pipe section 30 is provided with a second connecting flange 401.

[0087] Step 2: Connecting the adjustable pump pipe section:

[0088] Step 201: Connect the first connecting flange 101 in the first adjustable pump pipe section 7 to the inlet flange of the upper pump pipe 6, and connect the second connecting flange 401 in the first adjustable pump pipe section 7 to the outlet flange of the lower pump pipe 5; wherein the lower pump pipe 5 and the upper pump pipe 6 are arranged vertically.

[0089] Step 202: Connect the second connecting flange 401 in the second adjustable pump pipe section 7 to the outlet flange of the upper pump pipe 6 through the middle slewing bearing 12, and connect the first connecting flange 101 in the second adjustable pump pipe section 7 to the inlet flange of the outlet pump pipe section 11.

[0090] Step 203: Move the outlet pump pipe section 11 to the elevation of the main building roof to be poured; wherein, the lower pump pipe 5 passes through the elevator shaft, and the end of the lower pump pipe 5 extending out of the elevator shaft is connected to the concrete pump.

[0091] Step 3: Concrete pouring for the main building roof:

[0092] The concrete pump is operated to deliver concrete through the lower pump pipe 5, the first adjustable pump pipe section 7, the upper pump pipe 6, the second adjustable pump pipe section 7 and the outlet pump pipe section 11 to the pouring elevation of the main building roof 8, so as to realize the concrete pouring at the main building roof 8.

[0093] Step 4: Adjustment of the adjustable pump pipe section by rotation:

[0094] Step 401: Stop the concrete pump and rotate the other end of the third pump pipe section 30 in the first adjustable pump pipe section 7 relative to the end of the fourth pump pipe section 40, rotate the other end of the second pump pipe section 20 relative to the end of the third pump pipe section 30, and rotate the one end of the first pump pipe section 10 relative to the one end of the second pump pipe section 20, so that the center line of the first connecting flange 101 and the center line of the second connecting flange 401 are at 90°; wherein, the upper pump pipe 6 is vertically arranged along the stairwell wall, and the lower pump pipe 5 is arranged parallel to the center line of the upper pump pipe 6;

[0095] Step 402: In the second adjustable pump pipe section 7, the second connecting flange 401 rotates relative to the outlet flange of the upper pump pipe 6 through the middle slewing bearing 12, so that the outlet pump pipe section 11 rotates to the ladder shaft roof 9.

[0096] Step 403: Adjust the length of the outlet pump pipe section 11 so that the outlet of the outlet pump pipe section 11 meets the pouring elevation of the elevator shaft roof 9.

[0097] Step 5: Concrete pouring for the elevator shaft roof and machine room roof:

[0098] Step 501: Operate the concrete pump. The concrete pump delivers concrete through the lower pump pipe 5, the first adjustable pump pipe section 7, the upper pump pipe 6, the second adjustable pump pipe section 7, and the outlet pump pipe section 11 to the concrete pouring elevation of the elevator shaft roof 9, thereby realizing the concrete pouring at the elevator shaft roof 9.

[0099] Step 502: Adjust the length of the outlet pump pipe section 11 so that the outlet of the upper pump pipe 6 meets the pouring elevation of the machine house roof 4, and operate the concrete pump to deliver the lower pump pipe 5, the first adjustable pump pipe section 7, the upper pump pipe 6, the second adjustable pump pipe section 7 and the outlet pump pipe section 11 to the pouring elevation of the machine house roof 4, so as to realize the concrete pouring at the machine house roof 4.

[0100] In this embodiment, the rotating component at one end of the first pump pipe section 10 and one end of the second pump pipe section 20 is referred to as the first rotating component 1, the rotating component between the other end of the second pump pipe section 20 and one end of the third pump pipe section 30 is referred to as the second rotating component 2, and the rotating component installed between the other end of the third pump pipe section 30 and one end of the fourth pump pipe section 40 is referred to as the third rotating component 3.

[0101] The other end of the third pump pipe section 30 is rotated relative to one end of the fourth pump pipe section 40 via the third rotating component 3, and the other end of the second pump pipe section 20 is rotated relative to one end of the third pump pipe section 30 via the second rotating component 2. The method for rotating one end of the first pump pipe section 10 relative to one end of the second pump pipe section 20 via the first rotating component 1 is the same. The specific process is as follows:

[0102] Rotate nut 1-37, spring 1-36 extends along connecting rod 1-35 until it is in a free state. Continue to rotate nut 1-37, and ensure that nut 1-37 always fits against the extended end of spring 1-36. This reduces the length of connecting rod 1-35 extending out of annular part 1-4. Connecting rod 1-35 then drives rotary support 1-3 to move away from annular part 1-4, so that there is a gap between sealing ring 1-7 and annular part 1-4.

[0103] Then the inner ring 1-31 rotates relative to the outer ring 1-32, or the outer ring 1-32 rotates relative to the inner ring 1-31;

[0104] Then, rotate the nut 1-37 in the opposite direction to increase the length of the connecting rod 1-35 extending out of the annular part 1-4. The connecting rod 1-35 then drives the rotary support 1-3 to move closer to the annular part 1-4, so that the sealing ring 1-7 is tightly sealed against the annular part 1-4. Continue to rotate the nut 1-37 in the opposite direction, and the nut 1-37 will compress the spring 1-36 until the spring 1-36 is at its maximum extension.

[0105] In this embodiment, it should be noted that both the upper pump pipe 6 and the lower pump pipe 5 include multiple pump pipe sections connected in sequence.

[0106] In this embodiment, it should be noted that when concrete pouring is required at the elevator shaft roof 9 and the machine room roof 4, it is not necessary to remove the lower pump pipe 5 passing through the elevator shaft. After adjusting the upper pump pipe 6 from the horizontal direction to the vertical direction, only the length of the outlet pump pipe section 11 needs to be adjusted to carry out concrete pouring at the elevator shaft roof 9 and the machine room roof 4.
