Description

Technical Field

[0001] This application relates to the field of concrete pumping equipment, and more particularly to a buffer device for pumping concrete. Background Technology

[0002] With the development of the construction industry, the span and floor height of concrete structures are becoming increasingly larger. More and more projects are adopting steel-concrete composite slab construction techniques that require no formwork support or prefabricated composite slab construction with minimal support. Concrete pouring is mostly done using truck-mounted pumps or ground pumps. Concrete slabs have high requirements for impact loads during pouring. Considering the large impact force of concrete falling vertically through the pump pipe, which can easily cause impact deformation of the support structure and even safety accidents, concrete pumping technology plays an irreplaceable role in modern construction. By transporting concrete from the mixing equipment to the pouring point through high-pressure pipelines, it significantly improves construction efficiency and reduces labor costs. However, with the continuous expansion of construction project scale and the increasing complexity of the construction environment, the impact force problem caused by excessively high pumping speeds is gradually becoming apparent.

[0003] During the pouring of concrete floor slabs, the requirements for impact loads are high. Considering the large impact force generated when concrete falls vertically through the pump pipe, it is easy to cause impact deformation of the support frame, and even cause safety accidents. This impact force not only places higher demands on the stability of the pump pipe and its connecting components, but may also seriously affect the formwork, reinforcing steel, and other structures, even causing formwork bursting or damage, thus threatening the safety of the formwork support system. Therefore, how to effectively mitigate the impact force generated during pumping has become a key issue that needs to be addressed. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a buffer device for pumping concrete.

[0005] The buffer device for pumping concrete provided in this application adopts the following technical solution: A buffer device for pumping concrete, used in a concrete pump pipe, comprising:

[0006] The mounting assembly is connected to the concrete pump pipe;

[0007] A buffer mechanism is installed on the mounting assembly and located directly below the concrete pump pipe, the buffer mechanism being used to reduce the impact force of concrete discharged from the concrete pump pipe.

[0008] By adopting the above technical solution, the mounting components can be securely installed on the concrete pump pipe, providing reliable support for the buffer mechanism. Located directly below the concrete pump pipe, the buffer mechanism effectively reduces the impact force generated when concrete is discharged from the pump pipe, thereby protecting the concrete pump pipe and its surrounding structures from damage and extending the equipment's service life.

[0009] Preferably, the mounting assembly includes a connecting plate and a mounting frame. The connecting plate has a circular hole corresponding to the size of the inlet of the concrete pump pipe. The connecting plate is connected to the inlet of the concrete pump pipe. The mounting frame is detachably fixed to the connecting plate. The top of the mounting frame that contacts the connecting plate has a threaded hole with a diameter larger than that of the circular hole.

[0010] By adopting the above technical solution, the connecting plate is connected to the inlet of the concrete pump pipe, ensuring a stable installation of the device. The mounting frame is fixed to the connecting plate in a detachable manner, facilitating quick installation and maintenance. The threaded hole at the top of the mounting frame has a larger diameter than the circular hole, providing sufficient operating space for the subsequent installation of the buffer mechanism, thus improving installation efficiency and flexibility.

[0011] Preferably, the buffer mechanism includes a diverter and a rectifier assembly. The diverter is fixed to the top of the mounting frame through the threaded hole, and the rectifier assembly is located at both ends of the inner wall of the mounting frame.

[0012] By adopting the above technical solution, the buffer mechanism, including a diverter and a rectifier, can effectively reduce the impact force of concrete discharged from the concrete pump pipe. Specifically, the diverter is fixed to the top of the mounting frame via threaded holes, achieving a stable connection between the buffer mechanism and the mounting components, ensuring the stability of the overall structure, and facilitating disassembly and maintenance. The rectifier, located at both ends of the inner wall of the mounting frame, further rectifies and guides the diverted concrete, reducing turbulence during concrete flow, thereby reducing impact and wear on the equipment and extending its service life.

[0013] Preferably, the diverter is provided with an inlet pipe and two outlet pipes. The inlet pipe is provided with a thread that mates with the threaded hole, and the two outlet pipes are symmetrically arranged and extend obliquely downward.

[0014] By adopting the above technical solution, the buffer device can effectively reduce the impact force when concrete is discharged from the concrete pump pipe. The specific effects are as follows: the inlet pipe and the threaded hole cooperate to ensure that the diverter is firmly installed on the top of the mounting frame, improving the stability of the overall structure; the two outlet pipes are symmetrically arranged and extend diagonally downward, which can divert the concrete discharged from the concrete pump pipe, disperse the impact force, avoid high pressure impact in one direction, thereby protecting the pump pipe and surrounding structure and extending the service life of the equipment.

[0015] Preferably, the rectifier assembly includes an inclined baffle and a horizontal support plate, the horizontal support plate being located below the inclined baffle and connected to the inclined baffle, the inclined baffle being arranged perpendicular to the discharge pipe, and the inclined baffle being located in the discharge direction of the discharge pipe.

[0016] By adopting the above technical solution, the inclined baffle in the rectifier assembly can effectively change the flow direction of concrete, causing the concrete to be blocked and redirected when it exits the discharge pipe, thereby preventing the concrete from directly impacting the structure below and reducing the damage to the equipment caused by the impact force. The horizontal support plate provides stable support for the inclined baffle, ensuring that the inclined baffle will not shift or deform when subjected to concrete impact, further improving the stability and reliability of the buffer device.

[0017] Preferably, the buffer mechanism further includes a horizontal baffle located directly below the mounting frame. A connecting rod is connected to the bottom of the mounting frame, and the horizontal baffle is connected to the connecting rod.

[0018] By adopting the above technical solution, the horizontal baffle is positioned directly below the mounting frame, effectively blocking and dispersing the direct impact of concrete discharged from the concrete pump pipe on the ground or equipment below, thereby protecting the facilities below and reducing noise. Connecting rods link the horizontal baffle to the mounting frame, ensuring structural stability while facilitating assembly and disassembly. Furthermore, the cooperation between the horizontal baffle and the mounting frame enhances the overall buffering effect of the device, improving construction safety.

[0019] Preferably, the external dimensions of the horizontal baffle are larger than the external dimensions of the mounting frame, and the top of the horizontal baffle is a dome shape with an upward convex shape.

[0020] By adopting the above technical solution, the external dimensions of the horizontal baffle are larger than those of the mounting frame, which effectively expands the buffer area, making the impact force of concrete discharge more dispersed, thereby improving the stability of the overall structure. The top of the horizontal baffle is designed as an upward-convex spherical crown, which can further optimize the force transmission path, reduce the direct impact of the impact force on the central area of ​​the horizontal baffle, extend the service life of the horizontal baffle, and at the same time help guide the flow direction of concrete and avoid material accumulation.

[0021] Preferably, the mounting frame is a hollow structure, and spiral connecting rings are respectively provided around the bottom of the outer wall of the mounting frame.

[0022] By adopting the above technical solution, the hollow structure design of the mounting frame effectively reduces the overall weight and material costs, while improving the utilization rate of the internal space and facilitating the accommodation of the buffer mechanism. The spiral connecting rings around the bottom of the mounting frame enhance the connection stability between the frame and the external support structure, improve torsional resistance, and thus better adapt to the impact and vibration during concrete pumping.

[0023] Preferably, the connecting plate has positioning holes at its four corners, and the mounting frame has mounting holes on its top surface that correspond to the dimensions of the positioning holes.

[0024] By adopting the above technical solution, the positioning holes are distributed at the four corners of the connecting plate, ensuring rapid alignment between the connecting plate and the mounting frame during assembly, thus improving assembly accuracy and efficiency. Simultaneously, this design helps enhance the stability between the connecting plate and the mounting frame, preventing structural loosening or leakage caused by misalignment, thereby improving the overall reliability of the buffer device.

[0025] Preferably, there are four connecting rods, which are evenly distributed around the bottom of the mounting frame.

[0026] By adopting the above technical solution, four connecting rods are evenly distributed around the bottom of the mounting frame, ensuring the overall structural stability of the buffer device. Compared to other distribution methods, this even arrangement results in more balanced stress, effectively avoiding structural deformation or damage caused by uneven stress. At the same time, the four connecting rods simplify the structural complexity and reduce manufacturing costs while ensuring support strength.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By installing a buffer mechanism directly below the concrete pump pipe, the impact force generated on the pump pipe when concrete is discharged can be effectively reduced, thereby improving the stability of the pump pipe and its connecting parts, extending the service life of the equipment, and reducing safety hazards.

[0029] 2. The design of the mounting components and the buffer mechanism makes the device easy to install and highly adaptable, avoiding the problems of complex structure of traditional fixed brackets or inaccurate buffering effect of elastic element support methods;

[0030] 3. The design of the horizontal baffle and diverter in the buffer mechanism can not only disperse the impact force when the concrete is discharged, but also optimize the concrete flow path and improve the smoothness of the pumping process. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses a buffer device for pumping concrete.

[0039] Install component 2 and connect it to concrete pump pipe 1;

[0040] The buffer mechanism 3 is installed on the mounting assembly 2 and located directly below the concrete pump pipe 1. The buffer mechanism 3 is used to reduce the impact force of the concrete discharged from the concrete pump pipe 1.

[0041] refer to Figures 1-3The mounting assembly 2 includes a connecting plate 21 and a mounting frame 22. The connecting plate 21 is connected to the pipe opening of the concrete pump pipe 1, and the mounting frame 22 is detachably fixed to the connecting plate 21. Specifically, the connecting plate 21 has a circular hole 211 in the middle, the size of which corresponds to the opening of the concrete pump pipe 1. The opening of the concrete pump pipe 1 is a steel ring, which is welded to the circular hole 211. The connecting plate 21 is a rectangular plate, and positioning holes 212 are provided at the four corners of the connecting plate 21. The mounting frame 22 includes mounting holes 223, threaded holes 221, and connecting rings 222, which are provided at the top of the mounting frame 22 and correspond to the size of the positioning holes 212. The mounting frame is installed on the connecting plate 21 by bolts. When the mounting frame 22 is fixed, the threaded holes 221 are aligned with the central axis of the concrete pump pipe 1. The diameter of the threaded holes 221 is larger than that of the circular hole 211. The mounting frame 22 is a hollow rectangular body with an opening at the bottom. The connecting rings 222 are provided around the bottom of the outer wall of the mounting frame 22 and are spiral structures. There are four connecting rods 4. The connecting plate 21 can be made of high-strength carbon steel plate with a thickness of 10mm to 20mm.

[0042] refer to Figures 2-4 The buffer mechanism 3 includes a diverter 31, a rectifier 32, and a horizontal baffle 33. The diverter 31 is installed on the top of the mounting frame 22, the rectifier 32 is located at both ends of the inner wall of the mounting frame 22, and the horizontal baffle 33 is located directly below the mounting frame 22. The buffer mechanism 3 is used to reduce the impact force of concrete from the concrete pump pipe 1. Specifically, the diverter 31 is provided with an inlet pipe 311 and two outlet pipes 312. The inner diameter of the inlet pipe 311 is larger than the inlet size of the concrete pump pipe 1. The outer wall of the inlet pipe 311 is threaded 313. The inlet pipe 311 is aligned and installed in the threaded hole 221 of the mounting frame 22. The two outlet pipes 312 are symmetrically arranged on both sides of the inlet pipe 311 with the central axis as the center. For example, the inlet pipe 311 can be made of stainless steel with a smooth inner wall to reduce frictional resistance, an outer diameter of 150 mm, and a wall thickness of 8 mm. The discharge pipe 312 adopts a 45° downward angled design to create a diversion effect when the concrete flows out, thereby effectively reducing the impact force.

[0043] The rectifier assembly 32 includes a horizontal support plate 322 and an inclined baffle 321. The inclined baffle 321 is set perpendicular to the central axis of the discharge pipe 312. The concrete discharged from the discharge pipe 312 just hits the inclined baffle 321. The horizontal support plate 322 is set below the inclined baffle 321. The horizontal support plate 322 and the inclined baffle 321 are connected by welding. Both the horizontal support plate 322 and the inclined baffle 321 are welded to the inner wall of the mounting frame 22 to form a stable triangular structure, preventing the impact force of the concrete from being too large and damaging the rectifier assembly 32.

[0044] The top of the horizontal baffle 33 is a convex spherical crown, and the external dimensions of the horizontal baffle 33 are larger than the external dimensions of the mounting frame 22. One end of the connecting rod 4 is provided with a ring 41, which is fitted onto the spiral structure of the connecting ring 222. The end of the connecting ring 222 without the ring 41 is welded to the horizontal baffle 33. The concrete flow, which is slowed down by the rectifier assembly 32, flows onto the horizontal baffle 33. The convex spherical crown structure of the horizontal baffle 33 further processes the concrete, allowing it to flow smoothly into the building formwork.

[0045] The implementation principle of a concrete pumping buffer device according to an embodiment of this application is as follows: the concrete for pouring flows out from the concrete pump pipe 1 and into the feed pipe 311 of the diversion component 31. The two discharge pipes 312 divide the concrete in the feed pipe 311 into two streams. The diverted concrete flows from the discharge pipe 312 to the inclined baffle 321. The inclined baffle 321 reduces the impact force of the concrete. The reduced concrete flows to the horizontal baffle 33 and flows smoothly into the building formwork to be poured through the horizontal baffle 33.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
