[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-2 One embodiment of this utility model is a concrete conveying pump pipe elbow that is easy to clean, including a handle 1. The top of the outer wall of the handle 1 is provided with anti-slip texture to ensure the stability of the grip. The handle 1 is relatively long and can be used for concrete conveying pump pipe elbows of various lengths. The bottom of the handle 1 is provided with an adaptive component 2, which can automatically fit the bend of the concrete conveying pump pipe elbow.

[0019] Reference Figures 1-3The adaptive component 2 includes a protective sleeve 21, which is made of a flexible waterproof material. This type of material is a very common technology in the field, such as asphalt waterproof membrane and polyvinyl chloride waterproof membrane. The protective sleeve 21 is fixedly connected to the lower surface of the handle 1. A fixing plate 23 is fixedly connected to the lower surface of the handle 1. The fixing plate 23 is elongated, and guide grooves 24 are provided at both the upper and lower ends of the inner surface of the fixing plate 23. The guide grooves 24 are arc-shaped and have a span of less than 180 degrees. A sliding rod 26 is slidably connected to the inner wall of the guide groove 24. A slider 25 is fixedly connected to the outer wall of the sliding rod 26. A guide plate 22 is fixedly connected to the lower surface of the slider 25. 3 and guide plate 22 can provide stable support for protective sleeve 21. The initial position of slide bar 26 is located in the middle of guide groove 24, which makes the turning radius of guide plate 22 less than 90 degrees. This can ensure that guide plate 22, fixed plate 23 and protective sleeve 21 will not flip over, and can ensure the stability of the movement path. Connector 3 is fixedly connected to the lower surface of protective sleeve 21. Fixed component 6 is provided on the inner surface of connector 3. Fixed component 6 is used to fix push block 4. Push block 4 is provided at the bottom of fixed component 6. The bottom of push block 4 is conical, which can reduce the resistance to cleaning impurities in the bend of concrete conveying pump pipe. Sealing gasket 5 is fixedly connected to the outer wall of push block 4.

[0020] Reference Figure 1 , Figure 4 The protective sleeve 21 is fixedly connected to the outer wall of the fixed plate 23. The protective sleeve 21 can fix the fixed plate 23 and the guide plate 22, which can prevent the fixed plate 23 and the guide plate 22 from directly contacting impurities and provide a protective effect. Multiple sets of sliders 25 and sliders 26 are provided. The multiple sets of sliders 25 and sliders 26 are symmetrically distributed vertically around the center line of the guide plate 22. The guide plate 22 is set as a disc and penetrates the inner surface of the fixed plate 23. Multiple sets of guide plates 22 and fixed plates 23 are provided. The multiple sets of guide plates 22 and fixed plates 23 are longitudinally staggered, which allows the adaptive component 2 to automatically fit the bend of the concrete conveying pump pipe elbow. The lower surface of the bottom fixed plate 23 is fixedly connected to the upper surface of the connector 3, which can provide stable support.

[0021] Reference Figure 1 , Figure 4The fixing component 6 includes a plug 61, which is inserted into the lower surface of the connector 3. The contact surfaces of the plug 61 and the connector 3 are in contact, and the top of the plug 61 is chamfered to provide guidance during insertion. The outer wall of the plug 61 is fixedly connected to the connector 3 by a fixing bolt 62. The inner wall of the bottom end of the connector 3 is elastically connected to a collar 64 by an elastic element 63. The fixing bolt 62 passes through and is threadedly connected to the inner surface of the plug 61. The fixing bolt 62 is inserted into the inner surface of the connector 3. The connector 3 has through holes on both the front and rear sides to expose the screw groove of the fixing bolt 62 for easy unscrewing with a screwdriver. The collar 64 is fitted onto the outer wall of the fixing bolt 62 to protect the fixing bolt 62 and prevent impurities from accumulating in the screw groove of the fixing bolt 62.

[0022] Working principle: When in use, the operator holds the handle 1 and aligns the push block 4 with the inlet of the concrete delivery pump pipe elbow. During the pushing process, when the external force is applied, the adaptive component 2 plays a role. With the help of the slider 25 and the slide bar 26 sliding in the guide groove 24 on the fixed plate 23, multiple sets of fixed plates 23 and guide plates 22 can be bent and automatically fit the bend of the pump pipe elbow. At the same time, the protective sleeve 21 wraps around the fixed plate 23 and the guide plate 22 to prevent the parts from directly contacting impurities. The sealing gasket 5 on the outer wall of the push block 4 fits tightly against the inner wall of the pump pipe, which can efficiently push out residual concrete impurities in the pipe. The conical design reduces cleaning resistance.

[0023] When the push block 4 needs to be replaced or maintained, the pressing collar 64 releases the obstruction of the fixing bolt 62 and squeezes the elastic element 63 to generate a reaction force. Then, the fixing bolt 62 is unscrewed to complete the disassembly of the insert block 61 and the push block 4. Then, the required push block 4 is taken out, and the insert block 61 on it is aligned with the connector 3 and inserted. When the insertion is completed, the pressing collar 64 releases the obstruction, and the collar 64 squeezes the elastic element 63 to generate a reaction force. Then, the fixing bolt 62 is installed. When the installation is completed, the collar 64 is loosened, and the elastic element 63 pushes the collar 64 up to protect the fixing bolt 62, which can prevent impurities from accumulating in the screw groove and affecting the operation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
