Description

Technical Field

[0001] The utility model relates to the field of concrete conveying, in particular to an anti-blocking pumping device. Background Art

[0002] The pump pipe is the abbreviation of the concrete conveying pump pipe, which is a new type of construction engineering accessory product and is divided into truck pump pipes and ground pump pipes. The existing pump pipes have a simple structure. After being assembled completely, the concrete adhering to the inner wall of the pump pipe will solidify over time, resulting in a smaller flow rate or even blockage. Content of the Utility Model

[0003] Purpose of the utility model: The technical problem to be solved by the utility model is to provide an anti-blocking pumping device in view of the deficiencies of the prior art.

[0004] To solve the above technical problems, the utility model discloses an anti-blocking pumping device, which includes a pump pipe body. A fixed flange is arranged on one side of the pump pipe body, and a movable flange is arranged on the other side. The movable flange is connected to the pump pipe body through a first bearing. The inner wall of the fixed flange is connected to a cleaning mechanism through a second bearing. The cleaning mechanism includes a first connecting ring and a second connecting ring. More than three scraping rods are arranged between the first connecting ring and the second connecting ring. The first connecting ring is fixedly connected to the inner wall of the movable flange, and the second connecting ring is connected to the second bearing.

[0005] In the utility model, the first connecting ring, the second connecting ring and the inner diameter of the pump pipe body are adapted.

[0006] In the utility model, connection holes are arranged on the sides of the fixed flange and the movable flange.

[0007] In the utility model, a circle of rotating pry holes is arranged on the outer wall of the movable flange.

[0008] In the utility model, the scraping rods are arranged obliquely.

[0009] Beneficial effects: When the utility model is in use, adjacent movable flanges are connected, and the two movable flanges at the connection point can rotate, thereby driving the scraping rods to clean the inner walls of the two sections of pump pipes, preventing concrete from adhering to the inner walls and causing blockage. Description of the Drawings

[0010] The following further specific description of the utility model is made in conjunction with the drawings and specific embodiments, and the above and / or other advantages of the utility model will become clearer.

[0011] Figure 1 It is a structural schematic diagram.

[0012] Reference numerals in the drawings: 1, pump pipe body; 2, fixed flange; 3, movable flange; 4, first bearing; 5, second bearing; 6, first connecting ring; 7, second connecting ring; 8, scraping rod; 9, connecting hole; 10, rotating pry hole. Detailed implementation mode

[0013] Embodiment:

[0014] As Figure 1 , this embodiment provides an anti-blocking pumping device, including a pump pipe body 1. A fixed flange 2 is provided on one side of the pump pipe body, and a movable flange 3 is provided on the other side. The movable flange is connected to the pump pipe body through a first bearing 4. The inner wall of the fixed flange is connected to a cleaning mechanism through a second bearing 5. The cleaning mechanism includes a first connecting ring 6 and a second connecting ring 7. More than three scraping rods 8 are provided between the first connecting ring and the second connecting ring. The first connecting ring is fixedly connected to the inner wall of the movable flange, and the second connecting ring is connected to the second bearing. The first connecting ring, the second connecting ring and the inner diameter of the pump pipe body are adapted. Connecting holes 9 are provided on the sides of the fixed flange and the movable flange. A circle of rotating pry holes 10 is provided on the outer wall of the movable flange. The scraping rods are obliquely arranged.

[0015] When this embodiment is in use, the movable flanges of adjacent pump pipes are abutted and fastened with bolts. When the concrete pumping is finished, a crowbar is inserted into the rotating pry hole 10 to drive the scraping rod 8 to rotate, so as to scrape and clean the inner wall of the pump pipe body 1.

[0016] The present invention provides an idea and method for an anti-blocking pumping device. There are many methods and ways to specifically implement this technical solution. The above is only the preferred implementation mode of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be realized by the prior art.
