Description

Technical Field

[0001] This utility model relates to the field of construction engineering conveying technology, and in particular to an anti-blocking joint for concrete conveying pipes used in construction. Background Technology

[0002] Concrete delivery pipes for construction are specialized pipeline systems used to transport concrete during the construction process. At construction sites, concrete needs to be delivered to different construction locations, such as floors of high-rise buildings or various corners of large foundations. Concrete delivery pipes utilize the pressure generated by pumping equipment to transport mixed concrete from the batching plant or mixer truck to the designated pouring location. They enable both horizontal and vertical transport, significantly improving concrete transportation efficiency, ensuring the continuity and efficiency of concrete pouring, and guaranteeing the smooth progress of construction.

[0003] Construction sites are complex, and different projects have varying requirements for the distance and direction of concrete delivery. The limited length of a single concrete delivery pipe cannot meet the demands of long-distance, multi-directional delivery. Using connectors to link multiple delivery pipes allows for flexible combinations of pipe lengths and routes according to actual construction needs, enabling the delivery pipes to extend to every corner of the construction site, adapting to diverse construction environments, and achieving precise concrete delivery to different construction locations.

[0004] However, concrete is prone to clogging at joints. During transport, improper concrete mix proportions, such as insufficient cement, poor aggregate gradation, or an unsuitable water-cement ratio, can reduce its fluidity, leading to accumulation and blockage at joints. Furthermore, prolonged transport operations cause the concrete to gradually evaporate, increasing its consistency and reducing its fluidity, making it more susceptible to clogging at joints. In addition, unstable pumping pressure during transport can hinder the smooth flow of concrete within the pipes. Therefore, a blockage-resistant joint for concrete transport pipes in construction is proposed to address these issues. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an anti-clogging joint for concrete conveying pipes in building construction. It aims to improve the problem in the prior art where concrete is prone to accumulation and blockage at the joint due to unreasonable mix proportions, increased viscosity and reduced fluidity caused by prolonged water evaporation during conveying, and unstable pumping pressure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete conveying pipe anti-blocking joint for building construction, comprising a conveying pipe, wherein a joint is fixedly connected to the left side of the conveying pipe, and an anti-blocking mechanism is provided on the right side of the joint;

[0007] The anti-blocking mechanism includes an annular plate that contacts the outer arc surface of the connector. A driving component is provided on the left side of the annular plate, and an annular plate is provided on the left side of the driving component.

A striking hammer is fixedly connected to the bottom end of the guide plate, and a fixing ring is hinged to the bottom right side of the striking hammer. A stabilizing component is provided on the outer arc surface of the connector.

[0008] As a further description of the above technical solution:

[0009] The driving component includes an electric telescopic rod fixedly connected to the left side of the ring plate, and the left side of the electric telescopic rod is fixedly connected to the right side of the ring plate.

[0012] As a further description of the above technical solution:

[0013] The bottom left side of the hammer contacts the outer arc surface of the connector.

[0014] As a further description of the above technical solution:

[0015] The ring plate, the annular plate, and the fixed ring are all provided in two sets.

[0016] As a further description of the above technical solution:

[0017] The stabilizing component includes a stabilizing plate fixedly connected to the outer arc surface of the connector. A fixing plate is fixedly connected to the outer arc surface of the stabilizing plate. A square groove is formed on the side of the ring plate near the fixing plate. The inner surface of the square groove matches the outer wall of the stabilizing plate. A guide groove is formed on the side of the fixing ring near the stabilizing plate.

[0018] As a further description of the above technical solution:

[0019] The two sets of ring plates are fixedly connected by bolts, and the two sets of fixing rings are fixedly connected by bolts.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, through the cooperation between the conveying pipe, the joint and the anti-blocking mechanism, etc., during the concrete conveying process, the electric telescopic rod drives the annular plate to move, which in turn drives the fixed column and the slider to move, thereby causing the hammer to continuously strike the outer arc surface of the joint.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2 One embodiment of this utility model is a concrete conveying pipe anti-blocking joint for building construction, including a conveying pipe 1, a joint 2 fixedly connected to the left side of the conveying pipe 1, the conveying pipe 1 is used to convey poured concrete, and the joint 2 can be set to splice and extend multiple sets of conveying pipes 1 to facilitate subsequent conveying. This is prior art and will not be explained in detail here. An anti-blocking mechanism 3 is set on the right side of the joint 2; the anti-blocking mechanism 3 can reduce concrete blockage at the joint 2.

[0032] Reference Figures 2-4 The anti-blocking mechanism 3 includes an annular plate 301 that contacts the outer arc surface of the connector 2. A driving component is provided on the left side of the annular plate 301, and an annular plate 303 is provided on the left side of the driving component. The driving component connects the annular plate 301 and the annular plate 303, and the annular plate 303 can move to the right. A fixed post 304 is fixedly connected to the left side of the annular plate 303, and the two move along the same trajectory. A slider 307 is rotatably connected to the left side of the fixed post 304. A guide plate 305 is slidably connected to the left outer wall of the slider 307. When the fixed post 304 moves to the right, the slider 307 moves towards the connector 2. The guide plate 305 is positioned to engage with the slider 307. The 07 matching groove guides the slider 307. The guide plate 305 moves outward (away from the side of the connector 2). The bottom end of the guide plate 305 is fixedly connected to the hammer 306. When the slider 307 moves towards the connector 2, the hammer 306 moves upward. When the slider 307 returns to its original position, the hammer 306 returns to its original position. The bottom right side of the hammer 306 is hinged to a fixing ring 308, which supports the hammer 306. The outer arc surface of the connector 2 is provided with a stabilizing component 4, which supports the anti-blocking mechanism 3 and facilitates the installation and disassembly of the anti-blocking mechanism 3.

[0033] Reference Figures 2-4The driving component includes an electric telescopic rod 302 fixedly connected to the left side of the ring plate 301. The left side of the electric telescopic rod 302 is fixedly connected to the right side of the ring plate 303. The left movable end of the electric telescopic rod 302 drives the ring plate 303 to move. The inner surface diameters of the ring plate 301, the fixed ring 308, and the ring plate 303 are the same, which facilitates subsequent installation operations. The inner surfaces of the fixed ring 308 and the ring plate 303 are in contact with the outer arc surface of the connector 2. The contact setting enables the purpose of installation and disassembly. The bottom left side of the hammer 306 contacts the outer arc surface of the connector 2. The contact setting enables the connector 2 to be struck to generate vibration. The contact area between the hammer 306 and the connector 2 is made of rubber. The ring plate 301, the ring plate 303, and the fixed ring 308 are all provided in two sets. The two sets of settings allow for quick disassembly by moving to both sides after the limit is released.

[0034] Reference Figures 2-3 and Figure 5 The stabilizing component 4 includes a stabilizing plate 401 fixedly connected to the outer arc surface of the connector 2. A fixing plate 402 is fixedly connected to the outer arc surface of the stabilizing plate 401. The fixing plate 402 and the stabilizing plate 401 serve to position and stabilize the device. A square groove is formed on the side of the ring plate 301 near the fixing plate 402. The inner surface of the square groove matches the outer wall of the stabilizing plate 401. The matching facilitates positioning and installation. After installation, the ring plate 301 is constrained by the stabilizing plate 401. A guide groove is formed on the side of the fixing ring 308 near the stabilizing plate 401. The inner surface of the guide groove matches the outer wall of the fixing plate 402. The matching facilitates positioning and installation. After installation, the fixing ring 308 is constrained by the fixing plate 402. The two sets of ring plates 301 are fixedly connected by bolts. The two sets of ring plates 303 are fixedly connected by bolts. The two sets of fixing rings 308 are fixedly connected by bolts. The bolt connection can achieve the purpose of quick installation and fixation.

[0035] Working principle: When installing the anti-blocking mechanism 3, first, fit the two sets of ring plates 301, annular plates 303, and fixing rings 308 onto the connector 2. Since the square groove on the side of the ring plate 301 near the fixing plate 402 matches the outer wall of the stabilizing plate 401, and the guide groove on the side of the fixing ring 308 near the stabilizing plate 401 matches the outer wall of the fixing plate 402, quick positioning and installation are possible. After installation, use bolts to fix the two sets of ring plates 301, two sets of annular plates 303, and two sets of fixing rings 308 together, ensuring the anti-blocking mechanism 3 is stably installed on the connector 2. The stabilizing component 4 serves to position and stabilize the anti-blocking mechanism 3.

[0036] When a blockage risk occurs during concrete delivery, the electric telescopic rod 302 is activated, causing the annular plate 303 to move to the right. The fixed column 304 also moves to the right. As the fixed column 304 moves to the right, the slider 307, which is rotatably connected to it, slides within the groove of the guide plate 305, causing the guide plate 305 to move outwards. Since the bottom end of the guide plate 305 is fixedly connected to the striking hammer 306, the movement of the slider 307 causes the striking hammer 306 to move upwards. When the electric telescopic rod 302 retracts, it resets the annular plate 303, the fixed column 304, and the slider 307, and the striking hammer 306 also resets. This process repeats, with the striking hammer 306 continuously striking the outer arc surface of the joint 2. Because the contact area between the hammer 306 and the connector 2 is made of rubber, it can generate vibration to prevent concrete from clogging the connector 2 without damaging the delivery pipe 1. When the concrete delivery work is completed or maintenance of the anti-clogging mechanism 3 is required, unscrew the bolts connecting the two sets of ring plates 301, the two sets of ring plates 303, and the two sets of fixing rings 308. Since the inner surface diameters of the ring plates 301, fixing rings 308, and ring plates 303 are the same and all contact the outer arc surface of the connector 2, these components can move to both sides after the limit is released, thereby achieving quick disassembly of the anti-clogging mechanism 3.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
