Description

Technical Field

[0001] The utility model relates to the technical field of concrete conveying accessories, in particular to a pumping concrete converter. Background Art

[0002] With the development of infrastructure construction in my country, it is often necessary to carry out concrete construction on complex terrain or super-high buildings, and concrete pumps are often used to pump concrete. During concrete pumping construction, the concrete pump pipeline will be constantly switched or installed and disassembled to change the pouring location due to process, terrain and other reasons. Therefore, concrete converters for quickly switching concrete pipelines have appeared on the market.

[0003] However, in the prior art, such as the prior art with patent number: CN217998976U, the flow direction of the material is changed by sliding the feed pipe between the two discharge pipes; since the position of the feed pipe also needs to be changed when the flow direction of the material changes, material leakage is prone to occur between the connection between the feed pipe and the discharge pipe.

[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-3The utility model provides an embodiment: a pumping concrete converter, comprising a support frame 1, on which a first converter 3 and a second converter 4 with the same structure are provided, and the feed ports of the first converter 3 and the second converter 4 are connected to a provided connecting pipe 2; the first converter 3 comprises a valve body 30, the interior of the valve body 30 is provided with a valve flap 32, and the side of the valve body 30 is connected to a provided discharge pipe 31; the valve flap 32 slides inside the valve body 30 to cut off the communication between the discharge pipe 31 and the valve body 30 or to open the communication between the discharge pipe 31 and the valve body 30, so as to realize the switching of the material flow direction.

[0019] To sum up, by utilizing the sliding of the valve flap inside the valve body, the valve flap can be utilized to cut off the connection between the discharge pipe 31 and the connecting pipe 2 or to connect the discharge pipe 31 and the connecting pipe 2, thereby allowing the material in the connecting pipe 2 to flow outward along the corresponding converter. For example, when the first converter 3 is internally connected, the second converter 4 is closed; at this time, the material can only flow from the connecting pipe 2 to the discharge pipe 31 on the first converter 3; conversely, the first converter 3 is closed and the second converter 4 is opened, and at this time, the material inside the connecting pipe 2 flows from the connecting pipe 2 to the discharge pipe 31 on the second converter 4, thereby completing the change of material flow direction.

[0020] Since the material flow direction is controlled by the sliding of the valve flap 32, the connecting pipe 2 will not be displaced during material feeding, so the material leakage phenomenon can be effectively solved. In addition, the movement of the valve flap 32 can simply and conveniently change the material flow direction, and thus, compared with the prior art, the structure of the device is simplified and the use is also simple and convenient, especially, the use, maintenance and production costs are reduced.

[0021] Furthermore, since the end of the valve body 30 away from the connecting pipe 2 is movably connected to the fastener 33, and the middle part of the fastener 33 is threadedly matched with the screw 35 through the internal threaded hole 34, the user can rotate the screw 35 outside the valve body 30 to achieve the movement of the valve flap 32. In addition, since the fastener 33 is movably installed on the valve body 30, it is convenient to remove the valve flap 32 and the screw 35 to facilitate cleaning of the converter.

[0022] Furthermore, since the screw rod 35 is connected to the valve flap 32 after passing through the fastener 33, and the screw rod 35 is caused to rotate in the internal threaded hole 34 through the handle 36 provided on the screw rod 35 to cause the valve flap 32 to move, it is convenient for the user to cause the screw rod 35 to rotate and at the same time facilitate the disassembly of the screw rod 35 and the valve flap 32.

[0023] In summary, the device is convenient for users to operate and is also easy to disassemble, so as to clean the residue and replace the valve flap 32; wherein the fastener 33 is connected to the end of the valve body 30 in a threaded manner.

[0024] In order to facilitate the cleaning and assembly of the device, a connector 5 is provided on the end of the discharge pipe 31 away from the valve body 30 and the connecting pipe 2; wherein the connector 5 is preferably a nut or a clamp. Based on this, the connecting pipe 2 is separated from the two converters by disassembling the connector 5, so that the user can clean the residue inside the connecting pipe 2 and the two converters.

[0025] Furthermore, since the support frame 1 is also provided with a mounting frame 6, and the mounting frame 6 is connected to the support frame 1 to fix the first converter 3 and the second converter 4 on the support frame 1. Therefore, the converter can be fixed on the support frame 1 by using the mounting frame 6. Specifically, the number of the mounting frames 6 is two, and the two mounting frames 6 are symmetrically arranged on both sides of the discharge pipe 31.

[0026] To summarize, the two converters are assembled with the support frame 1 by putting the mounting frame 6 on the first converter 3 and the second converter 4, and then the connecting rod on the support frame 1 passes through the mounting frame 6 and is connected to the nut. Conversely, disassembling the nut facilitates the disassembly of the two converters, thereby making it possible to disassemble the various components of the device, which is convenient for the installation and replacement of parts and components, and also convenient for thorough cleaning of the various parts.
