Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a steel pipe column concrete pouring device with automatic non-return function. Background Art

[0002] In the field of heavy-duty plants in metallurgical engineering, plant columns are often designed as steel tube concrete columns. After the steel tube columns are manufactured and installed, concrete needs to be poured into the steel tube columns to improve their strength, rigidity, and bearing capacity. The general construction method is to open a hole near the bottom of the steel tube column, install a delivery pipe, and connect the outlet of the concrete delivery pump to it with the delivery pipe. The concrete is continuously injected into the steel column through the delivery pipe by pump pressure until the column is filled with concrete. There is a risk of high-pressure pipe burst during the pumping process. To prevent concrete from flowing back from the delivery pipe, after the concrete pumping and pouring is completed, the pump pressure needs to be controlled for 1-2 minutes, and a stop plate is manually inserted into the delivery pipe, or a stop valve is set and manually closed. The concrete pump pressure has not been released, and there is a certain risk of manual approach operation. Manual insertion of the stop plate is slow and time-consuming. If a stop valve is installed, the cost is high. Summary of the invention

[0003] The utility model aims to overcome the defects of the prior art and provide a steel pipe column concrete pouring device with automatic check function to solve the problem of high-pressure pipe bursting risk during the pumping process.

[0004] In order to solve the above technical problems, the utility model is achieved as follows:

[0005] A steel pipe column concrete pouring device with automatic non-return function, characterized in that it comprises a delivery pipe, a one-way non-return plate and a pump connecting pipe, one end of the delivery pipe is bent and inserted into a hole at the bottom of the steel pipe column, the other end of the delivery pipe is connected to one end of the pump connecting pipe, and the other end of the pump connecting pipe is connected to the pump pipe of a concrete pump truck, and the one-way non-return plate is arranged in the pump connecting pipe to control the reflux of concrete.

[0006] The one-way check plate comprises two semicircular plates, which are connected to form a complete circular structure by a rotating shaft, the length of the rotating shaft is the inner diameter of the connecting pump pipe, and the two ends of the rotating shaft are welded to the inner wall of the connecting pump pipe; the two semicircular plates are provided with a first limit block on the side facing the steel pipe column to ensure that the two semicircular plates will not stick together during pouring, and the other side of the two semicircular plates are provided with a second limit block to control the one-way check plate to remain vertical when controlling the concrete backflow.

[0007] The automatic non-returnable steel pipe column concrete pouring device is characterized in that: after the two first limit blocks are fitted together, the opening angle of the two semicircular plates is 60°; after the two second limit blocks are fitted together, the two semicircular plates are in a vertical state and form a complete circle to block the backflow of concrete.

[0008] The automatic non-returnable steel pipe column concrete pouring device is characterized in that the bending angle of one end of the conveying pipe is 45°.

[0009] The automatic non-returnable steel pipe column concrete pouring device is characterized in that the delivery pipe and the pump pipe are connected by connecting plate bolts.

[0010] The automatic non-returnable steel pipe column concrete pouring device is characterized in that it also includes a reinforcing hoop which is sleeved on the outside of the pump pipe.

[0011] The automatic non-returnable steel pipe column concrete pouring device is characterized in that the rotating shaft is round steel.

[0012] The automatic non-returnable concrete pouring device for steel pipe columns is characterized in that the limit block is an iron block.

[0013] The beneficial effects of the utility model are as follows: It can be seen from the above technical scheme that the present application provides a steel pipe column concrete pouring device with automatic check function. After the steel pipe column is filled with concrete, the pump pressure can be reduced, and the concrete can be prevented from flowing back from the delivery pipe by relying on its own weight. No manual operation is required, and the operation is convenient, safe, and efficient. The device is simple to manufacture and has good operability. The device includes a delivery pipe (with a connecting plate), a one-way check plate, and a pump pipe (with a connecting plate). The one-way check plate is installed in the pump pipe. During pouring, concrete is flushed open from the one-way check plate by the pump pressure from the pump pipe, and poured into the steel pipe column through the delivery pipe. After the pouring is completed, the pump pressure is released, and the concrete acts on the one-way check plate by relying on its own weight. The limit block set on the one-way check plate returns the one-way check plate to a vertical state to prevent concrete from flowing back. To facilitate the cleaning of the one-way check plate, the connection between the pump pipe and the delivery pipe is detachable. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.

[0021] like Figure 1 As shown: a steel pipe column concrete pouring device with automatic non-return function, which includes a delivery pipe 1, a one-way non-return plate 5 and a pump pipe 10. One end of the delivery pipe is bent and inserted into a hole at the bottom of the steel pipe column 11, the other end of the delivery pipe is connected to one end of the pump pipe, and the other end of the pump pipe is connected to the pump pipe of a concrete pump truck. The one-way non-return plate is arranged in the pump pipe to control the reflux of concrete.

[0022] like Figure 2 , 3 As shown: Specifically, the one-way check plate includes two semicircular plates, which are connected to form a complete circular structure through a rotating shaft 4. The length of the rotating shaft is the inner diameter of the connecting pump pipe, and both ends of the rotating shaft are welded to the inner wall of the connecting pump pipe; the two semicircular plates are provided with a first limit block 7 on the side facing the steel pipe column to ensure that the two semicircular plates will not stick together during pouring, and the other side of the two semicircular plates is provided with a second limit block 8 to control the one-way check plate to remain vertical when controlling the concrete backflow.

[0023] Furthermore, after the two first limit blocks are attached, the opening angle of the two semicircular plates is 60°; after the two second limit blocks are attached, the two semicircular plates are in a vertical state and form a complete circle to block the backflow of concrete.
