Description

Technical Field

[0001] This invention relates to the field of concrete pumping technology, and in particular to a device for preventing blockage in concrete pumping pipes for high-rise buildings. Background Technology

[0002] Concrete pouring for building construction requires pumping concrete to the work site. Existing anti-clogging pipes use U-shaped bolts and clamps to fix the pipes. Pumping vibration easily causes stress concentration, bending, and breakage of the bolts; the supporting vibration mechanism is only installed at a single point using flanges and clamps, and the excitation force is concentrated at the connection point, which easily wears down the pipe wall. The overall fixing stability is poor, the pipe loss is large, and the construction practicality is insufficient.

[0003] A search revealed Chinese patent CN214838924U, which discloses a fixing device for concrete pumping pipelines in high-rise buildings, relating to the field of high-rise building technology. This utility model includes a base, a support cylinder fixedly disposed in the middle of the base, a connecting column sleeved inside the support cylinder, and a telescopic spring disposed on the bottom wall of the support cylinder. The other end of the telescopic spring is connected to the connecting column, and the other end of the connecting column is detachably connected to a fixing frame ring for fixing the pipeline. It features good transportation safety, high applicability, and a simple structural principle.

[0004] Based on the above search and existing technology, the following findings were made:

[0005] The existing technology relies on spring connections, which can easily lead to spring fatigue or deformation due to long-term vibration, affecting the stability of the fixation. The overall single-point clamping has a small contact area with the pipe, which can easily cause stress concentration and aggravate pipe wall wear. In addition, the device lacks an active unblocking design for concrete blockage, so it has certain limitations. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a device for preventing blockage in concrete pumping pipes for high-rise buildings. This invention relies on a double-layer clamping structure to increase the pipe's fixed contact area and sets limits to prevent stress damage to the screw. At the same time, it relies on a support kit to widen the vibration transmission contact surface, avoiding localized stress damage to the pipe wall, thus simultaneously improving the fixing and anti-blocking effects.

[0007] The technical solution for achieving the purpose of this invention is: a device for preventing blockage in concrete pumping pipes of high-rise buildings, comprising a pipe, a vibrating motor, a mounting frame, and a support sleeve, and further comprising a fixing plate and a support base.

[0008] The fixing plate is fixedly installed inside the mounting frame, and a second arc-shaped bracket is installed on the fixing plate by bolts. A first arc-shaped bracket is provided on the outside of the second arc-shaped bracket.

[0009] The support seat is snapped onto the outside of the pipe, and a strip mounting plate is fixedly installed on the outside of the support seat.

[0010] Preferably, the inner sides of the second arc-shaped card seat and the support seat are provided with anti-slip textures, the two sides of the second arc-shaped card seat are provided with grooves, the two sides of the first arc-shaped card seat are provided with limit blocks, the two sides of the first arc-shaped card seat are fixedly installed with first skirts, the two sides of the second arc-shaped card seat are fixedly installed with second skirts, and the first skirts and the second skirts are provided with multiple through holes.

[0011] Preferably, the groove is adapted to the limiting block, a screw is installed through the interior of each through hole, a locking sleeve is fitted on the external thread of the screw, and multiple receiving grooves are opened on the side of each second skirt, with an elastic gasket inside each receiving groove.

[0012] Preferably, the vibration motor is fixedly installed on the outside of the strip mounting plate, and arc-shaped connecting blocks are fixedly installed at both the upper and lower ends of the support base. The support sleeve is fitted over the outside of the pipe, and an arc-shaped rim is fixedly installed on one side of the support sleeve. A flange is fixedly installed on the outside of the pipe, and the arc-shaped rim is connected to the flange by bolts.

[0013] The significant advantages of this invention compared to existing technologies are:

[0014] Firstly, this invention employs a split-type double-layer arc-shaped clamping structure paired with an integrated mounting frame. Positioning and clamping are achieved by two arc-shaped components encircling the pipe. The entire structure is assembled and disassembled using bolts, eliminating the need for welding. It is compatible with various specifications of pumping pipes. Compared to the traditional single-point fixing method of U-shaped clamps, the arc-shaped structure has a larger contact area with the pipe, allowing for more even distribution of vibration loads generated during pumping operations. This prevents localized stress concentration, ensures secure pipe fixing, and facilitates convenient disassembly, assembly, and transportation. It can be repeatedly used in construction on different floors.

[0015] Secondly, the present invention features a dual protective structure with limiting and buffering at the clamping and docking position. When the arc-shaped components are docked, the concave and convex structure ensures precise alignment and prevents the clamping components from shifting to the left or right. At the same time, an elastic buffer is set on the locking contact surface. The shear force generated by the vibration of the equipment can be absorbed and offset by the buffer, which greatly reduces the probability of the locking screw bending or breaking under alternating loads, improves the durability of the entire fixing structure, maintains a stable clamping effect even during long-term construction, and reduces the frequency of parts replacement.

[0016] Thirdly, this invention integrates the vibration unblocking mechanism with the pipe support structure. The vibration motor transmits excitation force through multiple sets of connecting components that adhere to the pipe wall at multiple points. Unlike the single-flange, single-point vibration mode, the vibration can evenly cover the pipe contact surface, resulting in better unblocking of blockages. The multi-point force transmission mode avoids the concentration of vibration stress in localized areas of the pipe, effectively preventing pipe wall fatigue damage. It combines the two functions of stable pipe fixation and rapid unblocking of concrete blockages, simplifying the on-site setup process.

[0017] This invention addresses the problems of existing technologies that rely on spring connections, which can lead to spring fatigue or deformation due to long-term vibration, affecting stability; the single-point clamping design with a small contact area with the pipe, which can easily cause stress concentration and exacerbate pipe wall wear; and the lack of an active unblocking design for concrete blockages.

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0028] This invention provides an improved device for preventing blockage in concrete pumping pipes of high-rise buildings. The technical solution of this invention is as follows:

[0029] Example 1

[0030] like Figures 1-2 As shown, a device for preventing blockage in concrete pumping pipes of high-rise buildings includes a pipe 1, a vibration motor 2, a mounting frame 3, and a support sleeve 4. It also includes a fixing plate 6 and a support base 19. The fixing plate 6, a first arc-shaped clamp 8, and a second arc-shaped clamp 10, together with the mounting frame 3, form the main fixing mechanism for the pipe 1. The double-layered arc-shaped clamps encircle the pipe 1. The modular assembly structure allows for easy disassembly and assembly and can adapt to different pipe diameters. The mounting frame 3 enables overall positioning of the pipe 1. The support sleeve 4 and support base 19 are designed with pre-reserved vibration installation points, integrating fixing and anti-blockage vibration functions into a single layout.

[0031] The fixing plate 6 is fixedly installed inside the mounting bracket 3. A second arc-shaped bracket 10 is installed on the fixing plate 6 by bolts. A first arc-shaped bracket 8 is provided on the outside of the second arc-shaped bracket 10.

[0032] The support base 19 is snapped onto the outside of the pipe 1, and a strip mounting plate 5 is fixedly installed on the outside of the support base 19.

[0033] Example 2:

[0034] Based on the device for preventing blockage of concrete pumping pipes in high-rise buildings provided in the first embodiment of this application, the second embodiment of this application proposes another device for preventing blockage of concrete pumping pipes in high-rise buildings. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0035] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] like Figures 3-6As shown, the inner sides of the second arc-shaped card holder 10 and the support seat 19 are provided with anti-slip textures 22. The two sides of the second arc-shaped card holder 10 are provided with grooves 15. The two sides of the first arc-shaped card holder 8 are provided with limit blocks 17. The two sides of the first arc-shaped card holder 8 are fixedly installed with first skirts 7. The two sides of the second arc-shaped card holder 10 are fixedly installed with second skirts 11. The first skirts 7 and the second skirts 11 are provided with multiple through holes 16. The anti-slip textures 22 increase the contact friction between the card holder, the support seat 19 and the pipe 1, and prevent the pipe 1 from slipping under pumping vibration. The limit blocks 17 and the grooves 15 engage with each other to limit the movement. The first skirts 7 and the second skirts 11 overlap and connect with the reserved through holes 16. The unified screw 9 locks the channel, the force is evenly distributed, and the overall clamping stability is improved.

[0037] Furthermore, the groove 15 is adapted to the limiting block 17, and a screw 9 is installed through the interior of each through hole 16. A locking sleeve 12 is fitted on the external thread of the screw 9. Multiple receiving grooves 13 are opened on the side of each second skirt 11. An elastic gasket 14 is provided inside each receiving groove 13. The limiting structure is precisely aligned, and the screw 9 and the locking sleeve 12 quickly lock the skirt. The elastic gasket 14 inside the receiving groove 13 buffers and offsets the shear stress during pumping vibration, prevents the screw 9 from fatigue deformation and breakage, and improves the durability of the clamping structure.

[0038] As a further embodiment of the present invention, the vibration motor 2 is fixedly installed on the outside of the strip mounting plate 5, and arc-shaped connecting blocks 18 are fixedly installed at both the upper and lower ends of the support base 19. The support sleeve 4 is sleeved on the outside of the pipe 1, and an arc-shaped rim 21 is fixedly installed on one side of the support sleeve 4. A flange 20 is fixedly installed on the outside of the pipe 1, and the arc-shaped rim 21 and the flange 20 are connected by bolts. The vibration motor 2 is externally mounted on the strip mounting plate 5. Through the support base 19, the arc-shaped connecting block 18, the support sleeve 4, and the arc-shaped rim 21, the pipe 1 flange 20 is contacted at multiple points, which increases the vibration transmission contact area, disperses the vibration evenly, avoids local stress concentration and damage to the pipe 1, and efficiently achieves anti-blockage and unblocking of the pipe 1.

[0039] The specific working method is as follows: During construction, the mounting frame 3 is first fixed in the pre-set position of the building. The second arc-shaped bracket 10 is assembled to the fixing plate 6 with bolts. The pipe 1 is inserted into the arc groove of the second arc-shaped bracket 10. The first arc-shaped bracket 8 is fastened to cover the outer wall of the pipe 1, so that the first skirts 7 on both sides are stacked on the second skirts 11. The limiting block 17 is embedded in the groove 15 to complete the alignment. After the screw 9 passes through the through hole 16, the locking nut 12 is tightened to lock the bracket. The elastic gasket 14 buffers the vibration shear force. Then, the support sleeve 4 is fixed to both sides of the flange 20 of the pipe 1 with the help of the arc-shaped rim 21. The strip mounting plate 5 is connected to the support sleeve 4 through the arc connecting block 18. The support seat 19 is attached to the outer wall of the pipe 1. The vibration motor 2 is installed on the outside of the strip mounting plate 5. When the concrete pumping causes pipe blockage, the vibration motor 2 is started. The vibration is evenly transmitted to the pipe 1 through the strip mounting plate 5, the support seat 19 and the support sleeve 4 to clear the blockage. After the operation is completed, the locking nut 12 and the arc-shaped bracket are disassembled in sequence to disassemble the device.
