Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes. Background Technology

[0002] A pump pipe is a specialized conduit for transporting concrete, typically made of high-strength materials to withstand the high pressure during concrete transport. Its primary function is to transport concrete from the batching plant or mixer truck to a designated location on the construction site, enabling long-distance, high-efficiency concrete transport. After use, concrete pouring pump pipes require internal cleaning. There are three main cleaning methods for concrete pouring pump pipes: high-pressure water flushing, compressed air purging, and chemical dissolution.

[0003] After use, the existing concrete pouring pump pipes need to be cleaned of residual cement. During the cleaning process, the concrete pouring pump pipes are installed. The original concrete pouring pump pipes were installed using bolt flange connections. Under high-frequency impact, the bolts may loosen, resulting in the inability to seal the connection of the concrete pouring pump pipe, which reduces cleaning efficiency. The installation time of the concrete pouring pump pipes is also long, which affects the cleaning speed. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes. It solves the technical problem that when the original concrete pouring pump pipe is installed using screw flange connection, the screws will loosen under high-frequency impact, resulting in the inability to seal the connection of the concrete pouring pump pipe, which reduces the cleaning efficiency and affects the cleaning speed due to the long installation time of the concrete pouring pump pipe.

[0005] According to one aspect, at least one embodiment of the present invention provides a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes, comprising: a pump pipe body, wherein slots are fixedly opened on both sides of the inner wall of the pump pipe body, a top outlet is fixedly opened on the outer side of the slots, and a first fitting ring is fixedly installed on the outer wall of the pump pipe body, and a sealing ring is fixedly installed at the upper end of the first fitting ring.

[0006] The connector tube is fixedly connected to the front of the pump tube body. A sealing sleeve is fixedly installed at the rear end of the connector tube. A groove is opened at the upper end of the outer wall of the connector tube, and connection holes are opened on both sides inside the groove. A torsion spring is installed inside the connection hole, and a clamping plate is fixedly connected to the upper end of the torsion spring.

[0009] For example, in at least one embodiment of the present invention, a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes is provided, which further includes: the slot is symmetrically installed on the upper and lower sides of the pump pipe body with the inside of the pump pipe body as the center reference, and the upper end of the top outlet is rectangular.

[0010] For example, in at least one embodiment of the present invention, a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes is provided, which further includes: the sealing sleeve has a conical structure, and the connector pipe and the pump pipe body are connected by an interlocking connection.

[0011] For example, in at least one embodiment of the present invention, a high-pressure sealing air blowing device for cleaning concrete pouring pump pipe is provided, which further includes: the groove is symmetrically installed on the upper and lower sides of the outer side of the connector pipe with the connector pipe as the center reference; the clamping plate is connected to the clamping groove by a torsion spring; and the number of clamping plates is two.

[0012] For example, in at least one embodiment of the present invention, a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes is provided, which further includes: the sliding groove is installed in front of the groove, the number of the sliding grooves is two, and the inside of the sliding groove is cross-shaped.

[0013] For example, in at least one embodiment of the present invention, a high-pressure sealing air blowing device for cleaning concrete pouring pump pipe is provided, which further includes: the upper end of the sliding block is cross-shaped, the second sealing ring and the third sealing ring have the same structure, the second sealing ring of the second fitting ring and the first sealing ring of the first fitting ring are connected in a fitting manner, and the fixing ring is sleeved on the upper end of the connector pipe.

[0014] The beneficial effects of the embodiments of this utility model are as follows:

[0015] In this invention, the original flange connection is abandoned. Instead, an insertion block is used to insert and fix the connector pipe into the pump pipe body.

The clamping plate is tilted when it pops out. The connector pipe is fixed again by the clamping between the clamping plate and the clamping slot. The above-mentioned setup allows for quick installation between the pump pipe and the connector pipe through insertion and clamping connection, reducing the original installation time and improving efficiency. In addition, in this device, a first fitting ring is added to the outside of the pump pipe. A hydraulic rod is used to push the second fitting ring, which fits and fixes with the first fitting ring, sealing the pipe. The above-mentioned setup is fixed by the sealing ring inside the fitting plate, sealing the outside of the pipe again after installation, increasing the overall sealing performance and reducing the occurrence of leakage.

[0030] like Figures 1-4As shown, it illustrates a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes according to an embodiment of the present invention, comprising: a pump pipe body 1, grooves 2 fixedly opened on both sides of the inner wall of the pump pipe body 1, a top outlet 3 fixedly opened on the outer side of the grooves 2, and a first fitting ring 4 fixedly installed on the outer wall of the pump pipe body 1, and a sealing ring 5 fixedly installed on the upper end of the first fitting ring 4.

[0031] The connector pipe 6 is fixedly connected to the front of the pump pipe body 1. A sealing sleeve 7 is fixedly installed at the rear end of the connector pipe 6. A groove 8 is opened at the upper end of the outer wall of the connector pipe 6, and a connection hole 9 is opened on both sides inside the groove 8. A torsion spring 10 is installed inside the connection hole 9, and a clamping plate 11 is fixedly connected to the upper end of the torsion spring 10.

[0032] For example, such as Figure 3 As shown, a sliding groove 12 is provided on one side of the outer end of the connector pipe 6, and an energy dissipation plate 13 is fixedly installed inside the connector pipe 6, with an opening 14 fixedly provided inside the energy dissipation plate 13.

[0033] For example, such as Figure 2 As shown, the slot 2 is symmetrically installed on the upper and lower sides of the pump pipe body 1 with the interior of the pump pipe body 1 as the center reference, and the upper end of the top outlet 3 is rectangular.

[0034] For example, such as Figure 3 As shown, the sealing sleeve 7 has a conical structure, and the connector pipe 6 and the pump pipe body 1 are connected by an interlocking connection.

[0035] For example, such as Figure 4 As shown, the groove 8 is symmetrically installed on the upper and lower sides of the outer side of the connector tube 6 with the connector tube 6 as the center reference. The clamping plate 11 is connected to the clamping groove 2 by the torsion spring 10. There are two clamping plates 11.

[0036] For example, such as Figure 3 As shown, the sliding groove 12 is installed in front of the groove 8. There are two sliding grooves 12, and the inside of the sliding groove 12 is cross-shaped.

[0037] In some examples, the pump tube body 1 has slots 2 on the top and bottom inside. When cleaning the inside, first place a cleaning ball inside the pump tube body 1, then disconnect the connection between the pump tube body 1 and the connector tube 6. Insert the connector tube 6 directly into the pump tube body 1. When the connector tube 6 enters the pump tube body 1, the retaining plate 11 in its groove 8 (under the action of the torsion spring 10) pops upwards. The front end of the popped-out retaining plate 11 then enters and abuts against the slot 2 inside the pump tube body 1. When the pump tube body 1 is subjected to an outward pulling force, the retaining plate 11 locks into the slot 2, thus firmly fixing the connector tube 6. When disassembling the connector tube 6, first move the connector tube 6 a short distance towards the inside of the pump tube body 1 (i.e., the insertion direction). At this time, the retaining plate 11 moves with the connector tube 6 towards the top outlet 3 of the slot 2. Guided by the top outlet 3, the retaining plate 11 is able to move out of the slot 2. Since the inner wall thickness of the pump tube body 1 is less than... The depth of the slot 2 is such that when the card plate 11 moves out of the slot 2, it contacts the inner wall of the pump pipe body 1 and is pressed by the inner wall of the pump pipe body 1, overcoming the elastic force of the torsion spring 10 and retracting into the groove 8 of the connector pipe 6. At this time, the connector pipe 6 is rotated to make the card plate 11 and the slot 2 misaligned. Finally, the connector pipe 6 can be pulled out and disassembled from the pump pipe body 1. A polyurethane conical sealing sleeve 7 is installed at the rear end of the connector pipe 6. When high-pressure gas is introduced, the gas pressure acts on the conical sealing sleeve 7, pushing it to expand and deform, tightly fitting the inner wall of the pump pipe body 1 to achieve a seal. Its sealing force automatically increases with the increase of gas pressure. In order to prevent the gas pressure from being too high and causing impact to the sealing sleeve 7, an energy dissipation plate 13 is added inside the connector pipe 6. Multiple openings 14 are opened on the energy dissipation plate 13. When the high-pressure gas flows through the openings 14, some of the energy is absorbed and dissipated by the energy dissipation plate 13, thereby reducing the gas pressure and impact.

[0038] For example, such as Figures 5-6 As shown, this invention illustrates a high-pressure sealing air blowing device for cleaning concrete pouring pump pipes in another embodiment, comprising: a sliding block 15 slidably connected inside a sliding groove 12, and a second fitting ring 16 fixedly installed at the outer end of the sliding block 15; a second sealing ring 17 fixedly installed at the upper end of the second fitting ring 16, and a third sealing ring 18 fixedly installed on the outer side of the second sealing ring 17; a hydraulic rod 19 fixedly installed behind the second fitting ring 16, and a fixing ring 20 fixedly installed at the rear end of the hydraulic rod 19.

[0039] For example, such as Figure 6 As shown, the upper end of the sliding block 15 is cross-shaped, the sealing ring 17 and the sealing ring 18 have the same structure, the sealing ring 17 of the second fitting ring 16 and the sealing ring 5 of the first fitting ring 4 form a fitting connection, and the fixing ring 20 is sleeved on the upper end of the connector tube 6.

[0040] In some examples, a first fitting ring 4 is installed on the outside of the pump tube body 1, and a hydraulic rod 19 is installed on the upper end of the connector tube 6 via a fixing ring 20. The output end of the hydraulic rod 19 is connected to and drives a second fitting ring 16. A cross sliding block 15 is installed on the inner side of the second fitting ring 16. The cross sliding block 15 is slidably connected to the sliding groove 12 provided on the connector tube 6. When the connector tube 6 is inserted into the pump tube body 1 and the internal snap-fit ​​connection is completed (as described above), the hydraulic rod 19 is activated. The hydraulic rod 19 pushes the second fitting ring 16 to move towards the first fitting ring 4 on the outside of the pump tube body 1, and the sliding block 15 slides against the sliding groove 12. The moving connection is achieved by the movement of the second fitting ring 16, which causes the cross sliding block 15 to slide within the sliding groove 12, guiding the second fitting ring 16 to smoothly and linearly approach the first fitting ring 4. Under the continuous pushing of the hydraulic rod 19, the second fitting ring 16 finally fits tightly against the first fitting ring 4 on the pump pipe body 1. A sealing ring 5 is installed on the inner side of the first fitting ring 4, and a sealing ring 17 is installed on the inner side of the second fitting ring 16. When the two rings fit tightly, the sealing ring 5 and the sealing ring 17 press against each other to form a sealing interface. The pressure applied and maintained by the hydraulic rod 19 ensures a continuous tight contact force between the sealing rings.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
