Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pump pipes and relates to a fixing structure of a vertical section of a concrete pump pipe. Background Art

[0002] Concrete pump pipe, also known as concrete delivery pipe, is an important component of concrete delivery equipment such as concrete pump trucks or trailer pumps. It is mainly used to continuously and efficiently transport the mixed concrete along the pipeline to the pouring site for construction pouring.

[0003] Concrete pump pipes are divided into many types, such as straight pipes, curved pipes, and reducers. The place where concrete is mixed is often at a certain distance from the place where concrete is poured. Therefore, multiple concrete pump pipes are often required to be connected to form a sufficiently long pipeline. In the process of conveying concrete, the concrete pump pipe has a large vibration, which will cause the concrete pump pipe as a whole to vibrate. Concrete pump pipes may break, especially when the concrete pump pipe passes through the suspended part of the floor. Since there is a lot of concrete in the concrete pump pipe, the vibration is particularly severe. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and proposes a fixing structure for a vertical section of a concrete pump pipe, and solves the technical problem of how to reduce the vibration of the vertical section of the concrete pump pipe and prevent the concrete pump pipe from breaking.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a fixing structure for a vertical section of a concrete pump pipe, characterized in that it includes two fixing bars in the shape of angle irons and used to be fixedly connected to floors, one side of each of the fixing bars is fixedly connected with a circular arc-shaped limiting ring and two spaced limiting plates, the limiting ring is located between the two limiting plates, the middle of the limiting ring is fixedly connected to the fixing bar, the two ends of the limiting ring are respectively fixedly connected to the outer ends of the corresponding limiting plates away from the fixing bar, the outer side of each limiting plate is fixedly connected with a fixing plate, and the two fixing plates located on the same side are locked by fasteners so that the limiting ring can be clamped outside the vertical section.

[0006] There is a hole in the floor for the concrete pump pipe to pass through. During installation, two limit rings are put on the outside of the vertical section of the concrete pump pipe, and then locked by fasteners to fix the two limit rings outside the vertical section, and then the fixing strip is fixed to the floor, so that the vertical section of the concrete pump pipe is fixed and positioned through the fixed structure, reducing the vibration of the vertical section of the concrete pump pipe and preventing the concrete pump pipe from breaking. The setting of the limit plate and the fixing strip enhances the strength of the limit ring, so that the limit ring can better clamp the vertical section of the concrete pump pipe, reduce the vibration of the vertical section of the concrete pump pipe, and prevent the concrete pump pipe from breaking.

[0007] In the above-mentioned fixing structure of the vertical section of the concrete pump pipe, the end faces of the two ends of the limiting ring and the end faces of the outer ends of the limiting plate are flush with the outer side wall of the limiting plate. This structure enables the limiting ring to better clamp the vertical section of the concrete pump pipe, reduce the vibration of the vertical section of the concrete pump pipe, and prevent the concrete pump pipe from breaking.

[0008] In the above-mentioned fixing structure of the vertical section of the concrete pump pipe, the limiting ring is semicircular. This structure enables the limiting ring to better clamp the vertical section of the concrete pump pipe, reduce the vibration of the vertical section of the concrete pump pipe, and prevent the concrete pump pipe from breaking.

[0009] In the above-mentioned fixing structure of the vertical section of a concrete pump pipe, a triangular support piece is fixedly connected to the fixing strip, and the two right-angled sides of the support piece are respectively fixedly connected to the two inner side walls of the fixing strip. The setting of the support piece can improve the strength of the fixing strip, thereby improving the strength of the fixing structure.

[0010] In the above-mentioned fixing structure of the vertical section of the concrete pump pipe, the support plate and the limit plate are arranged along the same plane. This structure enables the support plate to play a better supporting role, improves the strength of the fixing structure, and thus can better reduce the vibration of the concrete pump pipe.

[0011] In the above-mentioned fixing structure of the vertical section of a concrete pump pipe, the limiting piece is perpendicular to the fixing strip, and the fixing piece is perpendicular to the limiting piece.

[0012] In the above-mentioned fixing structure of the vertical section of a concrete pump pipe, the fastener is a combination of a bolt and a nut.

[0013] Compared with the prior art, the utility model provides a fixing structure for a vertical section of a concrete pump pipe, which is sleeved on the outside of the vertical section of the concrete pump pipe by two limiting rings, and then locked by fasteners, and then the fixing strip is fixed to the floor, so that the vertical section of the concrete pump pipe is fixedly positioned through the fixing structure, the vibration of the vertical section of the concrete pump pipe is reduced, and the concrete pump pipe is prevented from breaking.
