Description

Technical Field

[0001] This utility model relates to the field of concrete pump pipe elbow technology, and in particular to a pressurized elbow for concrete pump pipe with adjustable diameter. Background Technology

[0002] In the modern construction industry, concrete is one of the most important building materials in the world. It is used in huge quantities during construction. Conventional concrete pouring is carried out by concrete truck pumps and tower cranes. During the concrete transportation process, the direction of transportation is often changed by connecting the concrete pump pipe bend. However, the internal diameter of the existing concrete pump pipe bend is not adjustable, which causes a lot of frictional resistance at the bend and a lot of kinetic energy to be lost, affecting the distance of concrete transportation in the channel with the bend. Utility Model Content

[0003] The main purpose of this utility model is to solve the above-mentioned technical problems to a certain extent. It proposes a concrete pump pipe pressurization bend with adjustable pipe diameter, which can achieve the pressurization effect of concrete pump pipe by reducing the pipe diameter area inside the bend, thereby realizing the purpose of long-distance transportation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pressurized bend for a concrete pump pipe with adjustable diameter, comprising a bend body, connecting flanges for assembly at both ends of the bend body, a through groove communicating with the interior on the feed end side of the bend body, an mounting frame fitted over the bend body, a sealing sleeve sealing the through groove on the mounting frame, support rods erected on both sides of the mounting frame on the bend body, a push rod between the two support rods, and an adjusting baffle on the push rod, which, as the push rod moves, passes through the sealing sleeve and inserts into the interior of the bend body, and first limiting blocks are respectively provided at the upper and lower ends of the support rods and the push rod; a pressure gauge and a temperature gauge are provided on the bend body near the mounting frame.

[0005] In some embodiments, the mounting bracket includes an upper mounting bracket and a lower mounting bracket, the upper mounting bracket sealing the through groove and pressing the sealing sleeve, and the upper mounting bracket and the lower mounting bracket being fixedly assembled and connected by bolts.

[0006] In some embodiments, the cross-section of the through groove is semi-circular, and the structure of the adjusting baffle extending into the inner end of the bent pipe body is the same as that of the through groove.

[0007] In some embodiments, the support rod has a movable groove along its length, the protrusions at both ends of the push rod are engaged in the movable groove, and the outer surface of the support rod has an external thread around the position of the movable groove, and the first limiting block is threadedly assembled to the support rod.

[0008] In some embodiments, a second limiting block is provided at the portion of the protrusion extending out of the support rod.

[0009] In some embodiments, the bend body is configured with a 15-degree bend.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention monitors the internal pressure of the bend pipe when conveying concrete using a pressure gauge. Simultaneously, a push rod drives an adjusting baffle to move, allowing the baffle to be inserted into the bend pipe body. This adjusts the internal pipe diameter of the bend pipe body, thereby reducing the internal pipe area to achieve a pressurized concrete pump pipe effect. This enables long-distance conveying, simplifies construction operations, and reduces operational difficulty. Attached Figure Description

[0016] like Figure 1-3 As shown, this utility model provides a pressurized bend for a concrete pump pipe with adjustable diameter, including a bend body 1. The bend body 1 is made of wear-resistant alloy material with a wall thickness of 4.5mm. The bend body 1 is set at a 15-degree bend angle. Both ends of the bend body 1 are provided with connecting flanges 2 for assembly. Multiple bend bodies 1 can be assembled through the connecting flanges 2, so that the construction party can easily change the conveying direction and angle of the bend. The outer diameter of the connecting flange 2 is 285mm, the bolt hole spacing is 240mm, the bolt diameter is 22mm, the number of bolt holes is 8, and the flange thickness is 24mm. The additional torque generated on the cylinder or pipe when the flange deforms is small, which makes the overall assembly, installation and maintenance convenient.

[0017] Furthermore, a pressure gauge 3 and a temperature gauge 4 are installed near the mounting bracket 6 on the bent pipe body 1. The pressure gauge 3 monitors the internal pressure of the bent pipe body 1, and the temperature gauge 4 monitors the external temperature of the bent pipe body 1. A through groove 5 is provided on the side of the bent pipe body 1 at the feed end, which is connected to the interior. The through groove 5 has a semi-circular cross-section. The mounting bracket 6 is fitted over the bent pipe body 1. The mounting bracket 6 seals the through groove 5 with a sealing sleeve 7. Support rods 8 are erected on both sides of the mounting bracket 6 on the bent pipe body 1. The support rods 8 have movable grooves 9 along their length. A push rod 10 is provided between the two support rods 8. The protrusions at both ends of the push rod 10 are inserted into the movable groove 9, and the outer surface of the support rod 8 is provided with external threads around the movable groove 9. The push rod 10 is provided with an adjusting baffle 11, which is connected to the push rod 10 by bolts. As the push rod 10 moves, it passes through the sealing sleeve 7 and is inserted into the inside of the bent pipe body 1. The structure of the adjusting baffle 11 extending into the inner end of the bent pipe body 1 is the same as that of the through groove 5. The support rod 8 is provided with a first limiting block 12 at the upper and lower ends of the push rod 10. The first limiting block 12 is threaded onto the support rod 8. The part of the protrusion extending out of the support rod 8 is provided with a second limiting block 13.

[0018] This embodiment uses pressure gauge 3 to monitor the internal pressure of the bend body 1 when conveying concrete. At the same time, push rod 10 drives adjustment baffle 11 to move, so that adjustment baffle 11 is inserted into the bend body 1, thereby adjusting the pipe diameter inside the bend body 1. This reduces the pipe diameter area inside the bend to achieve the pressurization effect of the concrete pump pipe, thereby achieving the purpose of long-distance conveying, and facilitating the construction unit's operation and reducing the difficulty of operation.

[0019] During operation, first adjust the position of the first limiting block 12 located below the protrusion downwards, then press the push rod 10 downwards to move the adjusting baffle 11 downwards, so that the adjusting baffle 11 is inserted into the body of the bent pipe 1. After the protrusion abuts against the first limiting block 12 below, adjust the first limiting block 12 located above the protrusion so that the first limiting block 12 above abuts against the protrusion to fix the vertical position of the push rod 10. Finally, assemble the second limiting block 13 to the two protruding ends of the protrusion to fix the horizontal position of the push rod 10. The above structure fixes the position of the push rod 10, thereby ensuring the position of the adjusting baffle 11 and preventing the adjusting baffle 11 from moving during use.

[0020] In another embodiment, the mounting bracket 6 includes an upper mounting bracket 601 and a lower mounting bracket 602. The upper mounting bracket 601 seals the through groove 5 and presses the sealing sleeve 7. The upper mounting bracket 601 and the lower mounting bracket 602 are fixedly connected by bolts. This structure makes it easy to adjust the assembly position of the mounting bracket 6 on the bent pipe body 1, so that the upper mounting bracket 601 can ensure the pressing effect on the sealing sleeve 7.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
