A pump pipe fixing device and a concrete delivery apparatus

Abstract

This utility model discloses a pump pipe fixing device and a concrete conveying equipment. When in use, the base of the pump pipe fixing device is placed stably on the ground, and the pump pipe is fixedly installed on the fixing component in the horizontal direction. When the pump pipe starts to convey concrete, the impact force of the concrete on the pump pipe in all directions can be absorbed by the fixing component. After the fixing frame bears the load from the fixing component, it is transferred downward to the base through the bent column. Since the bent column adopts an inward bending design, its bending performance resists part of the load before it is transferred to the base, which can effectively resist the impact force of the pump pipe, thereby reliably fixing the pump pipe and preventing the pump pipe from bursting due to detachment from the fixing.

Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a pump pipe fixing device and a concrete conveying equipment. Background Technology

[0002] Common methods for concrete pouring include self-unloading, ground pumps, and overhead pumps. When the pouring surface is far below (or above) the concrete mixer truck, a combination of overhead and ground pumps is often used. Overhead pumps do not require support points; after the concrete is pumped from the mixer truck to the overhead pump pipe, the required area can be poured by adjusting the angle of the overhead pump. However, ground pumps, with their straight pipes, experience significant impact from the concrete pumping force at 90° bends across layers. If not properly secured, the bend can loosen, causing the pump pipe to burst open, releasing high-pressure concrete that could injure nearby workers. Current techniques often use temporary fixing components made of steel bars or pipes to secure the pump pipe, or use steel reinforcement bars to bind it. These methods are ineffective against the impact of concrete delivery, making the pump pipe highly susceptible to bursting. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a pump pipe fixing device and a concrete conveying equipment, which can solve the problem of poor impact resistance of the existing pump pipe fixing method.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: On the one hand, a pump pipe fixing device is provided, including a base, a fixing frame and a plurality of bent columns. The fixing frame is located above the base, and the two ends of the bent columns are respectively connected to the fixing frame and the base. The plurality of bent columns are all arc-shaped and all bend inward. A fixing member is fixedly provided on the fixing frame, and the fixing member is used to fix the pump pipe in the horizontal direction.

[0005] As a further improvement to the above technical solution, the fixing frame is a square frame, and two fixing members are provided, which are respectively fixedly installed on opposite sides of the fixing frame.

[0006] As a further improvement to the above technical solution, the fixing member is fixedly connected to both the upper and lower ends of the fixing frame, the fixing member and both sides of the fixing frame are spaced apart, and a support rod is connected between the fixing frame and the fixing member.

[0007] As a further improvement to the above technical solution, four support rods are provided, one end of each of the four support rods is connected to the fixing member, and the other end of each of the four support rods is connected to the four vertices of the side of the fixing frame.

[0008] As a further improvement to the above technical solution, the base is square, and four bent columns are provided. One end of each of the four bent columns is connected to one of the four vertices below the fixed frame, and the other end of each of the four bent columns is connected to the midpoint of one of the four sides of the base.

[0009] As a further improvement to the above technical solution, diagonal braces are provided at all four corners of the base.

[0010] As a further improvement to the above technical solution, the fixing member includes a fixing ring, the axial direction of which is horizontal.

[0011] As a further improvement to the above technical solution, both the base and the fixing frame are welded together from several square tubes.

[0013] On the other hand, a concrete conveying device is provided, including a pump pipe and the aforementioned pump pipe fixing device, wherein the bend of the pump pipe is fixed to the fixing device.

When the pump pipe starts to transport concrete, the impact force of the concrete on the pump pipe in all directions can be absorbed by the fixing component.

Since the bent column adopts an inward bending design, its bending performance resists part of the load before it is transferred to the base, which can effectively resist the impact force of the pump pipe, thereby reliably fixing the pump pipe and preventing the pump pipe from bursting due to detachment from the fixing.

[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0022] Please see Figure 1-2 This utility model provides a preferred embodiment of a pump pipe fixing device, including a base 1, a fixing frame 2, and several bent columns 3. The fixing frame 2 is located above the base 1, and the two ends of the bent columns 3 are connected to the fixing frame 2 and the base 1 respectively. All the bent columns 3 are arc-shaped and bent inward. A fixing member 21 is fixedly installed on the fixing frame 2, which is used to fix the pump pipe in the horizontal direction. When the pump pipe fixing device is in use, the base 1 is placed stably on the ground, and the pump pipe is fixedly installed on the fixing member 21 in the horizontal direction. When the pump pipe starts to transport concrete, the impact force of the concrete on the pump pipe in all directions can be absorbed by the fixing member 21. After the fixing frame 2 bears the load from the fixing member 21, it is transferred downward through the bent columns 3 to the base 1. Since the bent columns 3 adopt an inward bending design, their bending resistance resists part of the load before it is transferred to the base 1, which can effectively resist the impact force of the pump pipe, thereby reliably fixing the pump pipe and preventing the pump pipe from bursting due to detachment from the fixing.

[0023] In this embodiment, the fixed frame 2 is a square frame, and two fixing members 21 are provided. The two fixing members 21 are respectively fixed on the opposite sides of the fixed frame 2. The double fixing members 21 can more evenly distribute the vibration and impact force of the pump pipe when it is working under high pressure, and avoid displacement or loosening caused by excessive force on a single point.

[0024] The fastener 21 is fixedly connected to both the upper and lower ends of the fixed frame 2. The fastener 21 and the fixed frame 2 are separated by gaps on both sides. A support rod 22 is connected between the fixed frame 2 and the fastener 21. Specifically, the fastener 21, the fixed frame 2 and the support rod 22 are all fixedly connected by welding. Welding ensures that the fastener 21 and the fixed frame 2 are firmly connected. The support rod 22 is used to strengthen the connection between the fastener 21 and the fixed frame 2.

[0025] In this embodiment, four support rods 22 are provided. One end of each of the four support rods 22 is connected to the fixing member 21, and the other end of each of the four support rods 22 is connected to the four vertices of the side of the fixing frame 2. The four support rods 22 are evenly arranged around the fixing member 21, which can make the fixing member 21 bear force evenly around its perimeter and further enhance the stability of the fixing member 21.

[0026] The base 1 is square, and four bent columns 3 are provided. One end of the four bent columns 3 is connected to the four vertices below the fixed frame 2, and the other end of the four bent columns 3 is connected to the midpoint of the four sides of the base 1. When the pump pipe is fixed to the device, the impact force of the concrete in all four directions is transmitted to the base 1, which will generate a bending moment effect on the fixed device. The bending moment is borne by the diagonal structure of the base 1, which makes better use of the anti-overturning ability of the base 1 in the diagonal direction.

[0027] To further enhance the stability of the base 1, diagonal braces 11 are provided at all four corners of the base 1. This arrangement can enhance the base 1's resistance to lateral forces and deformation, reduce the weak stress at the corners, and further enhance the base 1's impact resistance.

[0028] In this embodiment, the fixing member 21 includes a fixing ring 211, the axial direction of the fixing ring 211 is horizontal. The pump pipe can be installed with the device by passing the pump pipe through the fixing ring 211. The structure is simple and easy to implement.

[0029] In other embodiments, the fastener 21 can also be a clamp, which can be used to fix pump pipes of different diameters, making it more versatile.

[0030] Both the base 1 and the fixing frame 2 are welded together from several square tubes. The square tubes have a square cross-section and have good bending, torsion and compressive strength. In addition, the square tubes are hollow structures, which make them lighter while ensuring strength, making them easier to transport and install, and reducing overall costs.

[0031] The bent column 3 is made of steel. Steel has good ductility and will not break suddenly after reaching the yield point, allowing for local plastic deformation. The bent column 3 made of steel has strong bending resistance and can withstand strong impact forces.

[0032] A preferred embodiment of this utility model also provides a concrete conveying device, including a pump pipe and the pump pipe fixing device described in the above embodiment. The bend of the pump pipe is fixed on the fixing member 21. The bend of the pump pipe is subjected to great impact from the concrete. Fixing the bend of the pump pipe to the pump pipe fixing device can effectively resist the impact and prevent the bend of the pump pipe from bursting.

[0033] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
