Description

Technical Field

[0001] This invention relates to the field of cleaning and sewage discharge devices, specifically a cleaning and sewage discharge device for concrete pump pipes. Background Technology

[0002] In the construction of high-rise and super high-rise buildings, the pump pipes need to be cleaned after the concrete is poured. During the cleaning process, a large amount of mortar containing cement slurry and aggregate will be generated. This slurry needs to be safely discharged from the height to the ground through a sewage discharge device arranged vertically along the floors to avoid contaminating the poured floor surface.

[0003] In the prior art, Chinese utility model patent with publication number CN224294237U discloses a sewage discharge assembly for cleaning concrete pump pipes, which includes multiple material passage pipes, constricted pipes and connecting pipes. The material passage pipes slide through positioning holes on the template and are limited to the template by a support plate. The upper end of the connecting pipe is connected to the small-diameter port of the constricted pipe, and the lower end slides into the adjacent lower material passage pipe. This assembly realizes the diversion and discharge of sewage from pump pipe cleaning to a certain extent.

[0004] However, the aforementioned existing technologies still have significant drawbacks in the cleaning and maintenance of the inner surface of the pipeline in practical use: the mortar and sewage discharged from the pump pipe cleaning contains a large amount of cement slurry, which easily adheres to the inner surface of the pipeline when flowing through the vertical sewage pipe. After drying, it forms hard scale. With the increase of cleaning times, the scale continues to thicken, gradually reducing the flow cross-section of the inner surface of the pipeline, seriously affecting the smoothness of subsequent sewage discharge, and even causing pipeline blockage. It is urgent to clean the inner surface of the pipeline to remove the scale. In the existing sewage discharge components, the connection between the feed pipe and the connecting pipe is mostly a simple axial insertion. When it is necessary to clean and maintain the inner surface of the pipeline to remove the scale, drainage and flushing can only be carried out from the top vertical pipe section. However, the flushing water flow decreases sharply after passing through multiple layers from top to bottom. The cleaning effect of the inner surface of the pipe section becomes worse as it goes down, making cleaning very difficult and seriously affecting the cleaning and maintenance efficiency of the sewage discharge device itself. Summary of the Invention

[0005] The purpose of this invention is to provide a concrete pump pipe cleaning and sewage discharge device to solve the problem mentioned in the background art that the scale buildup in the sewage discharge pipe is difficult to clean, which seriously affects the cleaning and maintenance efficiency of the sewage discharge device itself.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A concrete pump pipe cleaning and sewage discharge device includes: multiple riser sections and multiple connecting pipe sections; the riser sections and connecting pipe sections are alternately connected end to end to form a sewage discharge pipeline, the top riser section is used to receive mortar waste discharged from the pump pipe cleaning, the bottom connecting pipe section is connected to a transfer pipe, and the transfer pipe is connected to a discharge pipe; the connecting pipe section is an integrally formed structure, including a large-diameter straight pipe, a middle inverted frustum-shaped pipe and a small-diameter straight pipe connected sequentially from top to bottom, the inner ring of the connecting pipe section is a through hole of equal diameter at the top and bottom; the upper part of the large-diameter straight pipe has an upper embedded sliding groove, the lower end outer wall of the riser section slides in fit with the upper embedded sliding groove, the outer wall of the small-diameter straight pipe slides in fit with the lower embedded groove opened at the upper end of the riser section, and there is a gap between the bottom wall of the upper embedded sliding groove and the bottom end of the riser section for the connecting pipe section to slide upward, so that the connecting pipe section can be disassembled from two adjacent riser sections.

[0008] Preferably, each of the riser and connecting pipe sections is independently equipped with an inner lining pipe. The inner lining pipe includes a supporting inner lining section, at least one standard inner lining section, a compensating inner lining section and a connecting inner lining section that are spliced ​​together along the axial direction. Multiple inner lining pipes are connected end to end along the axial direction to form a complete inner lining pipeline.

[0009] Preferably, the upper ends of the standard lining section and the compensating lining section are provided with outwardly inclined upper overlapping slopes, and the lower ends of the supporting lining section and the standard lining section are provided with inwardly inclined lower overlapping slopes that cooperate with the upper overlapping slopes.

[0010] Preferably, the inner lining tube further includes two limiting rings, which are respectively disposed at the connection between the compensating inner lining section and the docking inner lining section, and at the connection between the docking inner lining section and the supporting inner lining section.

[0011] Preferably, the lower ends of the compensation liner section and the docking liner section are provided with outwardly inclined upper limit slopes, and the upper ends of the docking liner section and the support liner section are provided with outwardly inclined lower limit slopes. The limiting ring is composed of two semi-clamping limiting clamps spliced ​​together. The upper end of the limiting ring is provided with an inwardly inclined upper engagement slope that cooperates with the upper limit slope, and the lower end of the limiting ring is provided with a lower engagement slope that cooperates with the lower limit slope.

[0012] Preferably, the supporting inner lining section is fixed to the inner wall of the riser section, and the top of the supporting inner lining section is flush with the top of the riser section. The length of the mating inner lining section is equal to the axial length of the mating section, so that when the mating section is disassembled, the mating inner lining section can be moved out synchronously with the mating section.

[0013] Preferably, the axial length of the standard inner liner section is less than the axial length of the connecting pipe section.

[0014] Preferably, a suspension support lug is fixedly provided on the outer circumference of the riser section.

[0015] Preferably, binding lugs are fixedly provided on the outer circumferential surfaces of both the connecting pipe section and the riser section. The binding lugs are used to bind and fix the connecting pipe section to the adjacent riser section by binding ropes.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting an upper embedded sliding groove and a specific sliding distance between the riser section and the connecting pipe section, the connecting pipe section can first slide upward so that its lower end is completely removed from the lower embedded groove. Then, the upper riser section is pushed upward so that its bottom end is completely separated from the upper embedded sliding groove. This allows the connecting pipe section to be pulled out horizontally between the two riser sections. This structure enables the partial disassembly of the sewage pipe layer by layer. This allows for targeted cleaning and maintenance of the connecting pipe section and the inner surface of each riser section to remove accumulated dirt. This effectively solves the problem that the cleaning effect becomes worse and cleaning is difficult as you go down when simply flushing from the top.

[0018] 2. Each riser section and the connecting section are equipped with an independent inner lining pipe, and the length of the connecting inner lining section matches that of the connecting section. This allows the connecting inner lining section to be removed simultaneously when the connecting section is disassembled. For mortar dirt and scale that is heavily adhered and difficult to clean, the inner lining pipe of the corresponding layer can be directly removed and replaced, making the cleaning of scale on the inner surface of the pipeline more convenient and economical.

[0019] 3. The inner lining sections are joined by inclined overlapping slopes. When the upper and lower overlapping slopes are in contact, they can guide and center the sections during assembly, facilitating quick alignment and splicing of the inner lining sections and reducing the assembly difficulty when filling from below. At the same time, semi-clamping limit clamps are used at the connection between the butt lining sections and the supporting lining sections for axial limiting, which facilitates quick disassembly and assembly and makes it easier to clean and maintain the device itself.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 The present invention provides a technical solution.

[0031] A concrete pump pipe cleaning and sewage discharge device includes multiple riser sections 1 and multiple connecting pipe sections 5. The riser sections 1 and connecting pipe sections 5 are alternately connected end to end to form a sewage discharge pipeline. The top riser section 1 is used to receive mortar waste discharged from the pump pipe cleaning. The bottom connecting pipe section 5 is connected to the transfer pipe, and the transfer pipe is then connected to the discharge pipe to realize the sewage discharge path from the top riser section 1 to the discharge pipe.

[0032] Reference Figure 1 , Figure 3 and Figure 8 The connecting pipe section 5 is a one-piece molded structure, including a large-diameter straight pipe, a central inverted frustum-shaped pipe and a small-diameter straight pipe connected sequentially from top to bottom. The inner ring of the connecting pipe section 5 has through holes of equal diameter at the top and bottom to ensure that the inner wall of the sewage pipe is flush and to reduce the retention of mortar and dirt at the connection.

[0033] The lower outer wall of the riser section 1 is slidably fitted with the upper sliding groove 18 of the large-diameter straight pipe. Specifically, the large-diameter straight pipe has an upper sliding groove 18 for the bottom end of the riser section 1 to be inserted. The outer ring of the riser section 1 is in contact with the circumferential wall of the upper sliding groove 18. The inner ring of the riser section 1 is flush with the inner ring of the connecting pipe section 5. There is a sliding gap between the bottom wall of the upper sliding groove 18 and the bottom end of the riser section 1. This sliding gap provides space for the connecting pipe section 5 to slide upward.

[0034] The outer wall of the small-diameter straight tube of the connecting pipe section 5 is slidably fitted with the lower fitting groove 11 opened at the upper end of the riser section 1. Specifically, the top of the riser section 1 is provided with a lower fitting groove 11 for the small-diameter straight tube of the connecting pipe section 5 to be inserted, and the outer ring of the small-diameter straight tube of the lower part of the connecting pipe section 5 is in contact with the circumferential wall of the lower fitting groove 11.

[0035] Reference Figure 1 and Figure 2 The sliding distance is greater than the sum of the axial depth of the lower mounting groove 11 and the embedding depth of the bottom end of the riser section 1 embedded in the upper mounting sliding groove 18.

[0036] With this configuration, when the connecting pipe section 5 slides upward to its maximum distance, since the sliding distance is greater than the axial depth of the lower mounting groove 11 plus the embedding depth of the bottom end of the riser section 1 embedded in the upper mounting sliding groove 18, the small-diameter straight pipe can be fully removed from the lower mounting groove 11, and the large-diameter straight pipe can be fully separated from the bottom end of the riser section 1, thereby allowing the connecting pipe section 5 to be horizontally pulled out between two adjacent riser sections 1.

[0037] Reference Figure 1 Multiple evenly distributed binding lugs 6 are fixedly provided on the outer circumferential surfaces of both the connecting pipe section 5 and the riser section 1. After the connecting pipe section 5 is embedded in the lower mounting groove 11, ropes are tied between the binding lugs 6 on the connecting pipe section 5 and the binding lugs 6 on the riser section 1 to connect the upper connecting pipe section 5 and the lower riser section 1, reducing the possibility of the connecting pipe section 5 coming out of the lower mounting groove 11.

[0038] Reference Figure 1 Each riser section 1 is fixedly provided with a suspension support ear 3 on its outer circumference. During installation, the suspension support ear 3 is used to support the support template 4 with through holes. After the riser section 1 passes through the through holes of the support template 4, it is in a suspended state, providing operating space for the subsequent installation and disassembly of the connecting pipe section 5.

[0039] Reference Figure 1 , Figure 4 , Figure 5 and Figure 7 The specific structure of the inner lining tube is as follows:

[0040] Each riser section 1 and connecting section 5 has an independent inner liner pipe inside. Multiple inner liner pipes are connected end to end along the axial direction to form a complete inner liner pipe. The inner liner pipe includes a supporting inner liner section 2, at least one standard inner liner section 7, a compensating inner liner section 8, and a connecting inner liner section 9, which are spliced ​​together along the axial direction. The supporting inner liner section 2 is fixed to the inner wall of the riser section 1, and the fixed position is close to the bottom of the lower mounting groove 11. The top of the supporting inner liner section 2 is flush with the top of the riser section 1. The length of the connecting inner liner section 9 is the same as the axial length of the connecting section 5, so that when the connecting section 5 is disassembled, the connecting inner liner section 9 can be moved out synchronously with the connecting section 5.

[0041] Both the standard inner lining section 7 and the compensation inner lining section 8 have an outwardly inclined upper overlapping slope 12 at their upper ends, and both the support inner lining section 2 and the standard inner lining section 7 have an inwardly inclined lower overlapping slope 13 at their lower ends that cooperate with the upper overlapping slope 12. When the upper overlapping slope 12 and the lower overlapping slope 13 are in contact, they can play a guiding and centering role during the assembly process, which facilitates the quick alignment and splicing between the inner lining sections and reduces the assembly difficulty when filling from below.

[0042] The lower ends of the compensating liner section 8 and the connecting liner section 9 are provided with outwardly inclined upper limit slopes 14, and the upper ends of the connecting liner section 9 and the supporting liner section 2 are provided with outwardly inclined lower limit slopes 17.

[0043] Reference Figure 6 The limiting ring is composed of two semi-clamping limiting clamps 10 spliced ​​together. The upper end of the limiting ring is provided with an inwardly inclined upper engaging surface 15 that cooperates with the upper limiting inclined surface 14, and the lower end of the limiting ring is provided with a lower engaging inclined surface 16 that cooperates with the lower limiting inclined surface 17. The limiting ring is set at the connection between the compensating inner lining section 8 and the docking inner lining section 9, and at the connection between the docking inner lining section 9 and the supporting inner lining section 2, and is used to limit the axial relative position between the inner lining sections.

[0044] The axial length of the standard inner lining section 7 is less than the axial length of the connecting pipe section 5. The axial length of the compensating inner lining section 8 can be customized according to the remaining axial space inside the riser section 1 to compensate for the filling requirements of the remaining space between the standard inner lining section 7 and the connecting inner lining section 9 after they are connected in sequence.

[0045] Reference Figures 1 to 3 Taking the installation of one layer as an example, the specific installation steps are as follows:

[0046] S1, move the riser section 1 to the top of the upper support template 4, and vertically downward through the through hole of the support template 4 until the hanging support ear 3 rests on the support template 4. At this time, the riser section 1 is in a suspended state.

[0047] S2, the standard inner lining section 7 and the compensation inner lining section 8 are lifted from below and filled into the suspended riser section 1, and the sections are spliced ​​sequentially by the guiding cooperation of the upper overlapping slope 12 and the lower overlapping slope 13.

[0048] S3, insert the inner lining section 9 into the connecting pipe section 5, so that the connecting pipe section 5 fits over the inner lining section 9, and then lift the riser section 1 of this layer and move it upward (i.e., riser section 1 of S2) until there is a gap between the riser section 1 of this layer and the riser section 1 that has been installed on the lower layer, allowing the connecting pipe section 5 to move horizontally between them. Then move the connecting pipe section 5 and the inner lining section 9 inside it between the riser section 1 of this layer and the riser section 1 that has been installed on the lower layer.

[0049] S4. First, align the lower end of the connecting liner section 9 with the upper end of the supporting liner section 2 in the lower installed riser section 1. Then, place the two semi-clamping limit clamps 10 from the left and right sides between the connecting liner section 9 and the supporting liner section 2.

[0050] S5, insert the small-diameter straight pipe at the lower end of the connecting pipe section 5 into the lower mounting groove 11 at the upper end of the lower riser section 1.

[0051] S6, then take out two semi-clamping limit clamps 10 and place them between the docking liner section 9 and the compensation liner section 8 from the left and right sides respectively.

[0052] S7, the riser section 1 of this layer is placed downwards until the suspension support ear 3 rests on the support template 4. At this time, the bottom end of the riser section 1 is also embedded in the upper sliding groove 18 of the upper end of the connecting pipe section 5.

[0053] S8. Tie ropes between the connecting pipe section 5 and the binding lug 6 of the lower riser section 1 to complete the assembly of this layer.

[0054] Reference Figure 1 and Figure 2 When it is necessary to clean and maintain the inner surface of the sewage pipes on a certain floor to remove accumulated scale, the specific disassembly steps are as follows:

[0055] The first step is to release the binding ropes between the connecting pipe section 5 and the binding lugs 6 on the adjacent riser sections 1 above and below.

[0056] The second step is to slide the connecting pipe section 5 of this layer upwards, so that the small-diameter straight pipe can be effectively removed from the lower mounting groove 11 of the lower riser section 1.

[0057] The third step is to push the riser section 1 upward (the pusher section 1 utilizes the sliding space of the upper embedded sliding groove 18 located above the riser section 1), the maximum pushing distance is the sliding distance, so that the bottom end of the riser section 1 separates from the upper embedded sliding groove 18 of the connecting pipe section 5 of the layer.

[0058] Fourth step: At this point, both the upper and lower ends of the connecting pipe section 5 have been effectively disengaged from the adjacent riser section 1. Then, remove the semi-clamping limit clamps 10 at the upper and lower ends of the connecting liner section 9. Then, the connecting pipe section 5 can be moved horizontally to complete the disassembly of the connecting pipe section 5. The connecting liner section 9 is moved out synchronously with the connecting pipe section 5. After the connecting liner section 9 is missing, the compensation liner section 8 and the standard liner section 7 can slide out from the inside of the riser section 1. At this point, both the riser section 1 and the liner pipe of this layer are easy to clean.

[0059] For mortar stains and scale that are heavily adhered and difficult to clean, the corresponding sections of the inner lining pipe can be removed separately and the corresponding components can be replaced directly, making the cleaning of scale on the inner surface of the pipe more convenient and economical.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
