Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a concrete pouring device. Background Art

[0002] Concrete pouring is a common building construction technique used to create concrete structures, floors, pavements and other building elements.

[0003] Traditionally, before pouring, a formwork is installed on the construction area according to design requirements to define the shape and size of the concrete. The cement is then transported to the construction site by a pump truck and transported into the formwork through the folding arm of the pump truck. In order for the staff to adjust the direction of the falling cement, a slurry delivery hose is fixedly connected to the bottom end of the folding arm, and the drop position is adjusted by moving the slurry delivery hose away from one end of the folding arm. However, during use, the position of one end of the hose is changed directly by pushing the wall of the hose. There is a possibility of hand slippage during pushing, which causes the position of the slurry delivery hose to change. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4 A concrete pouring device shown in the figure includes a pump truck folding arm 1, the bottom end of the pump truck folding arm 1 is fixedly connected to a slurry delivery hose 2, the bottom of the slurry delivery hose 2 is provided with a moving component for moving the position of the slurry delivery hose 2, and the moving component includes a fixed sleeve 3 sleeved on the bottom of the slurry delivery hose 2, a movable sleeve 4 is threadedly sleeved on the middle part of the fixed sleeve 3, handles 5 are symmetrically fixedly connected on both sides of the movable sleeve 4, and a limiting member for limiting the rotation of the movable sleeve 4 is provided at the connection between the movable sleeve 4 and the fixed sleeve 3.

[0021] It should be noted that the folding arm 1 of the pump truck is composed of multiple sections, which can be extended and folded during construction to achieve a suitable length and angle; the folding arm is an important component of the pump truck, which can transport concrete to the mold position to meet different requirements for concrete transportation and pouring according to different needs; the slurry delivery hose 2 is made of wear-resistant and pressure-resistant rubber material, and has flexibility and durability. When in use, the slurry delivery hose 2 can be bent to adjust the position of the cement output by the slurry delivery hose 2. The fixed sleeve 3 and the movable sleeve 4 are both made of metal, so that when the handle 5 is used to push the movable sleeve 4 and the fixed sleeve 3, deformation of the two can be avoided.

[0022] Furthermore, a fixed sleeve 3 that cannot be deformed is provided at the bottom of the slurry delivery hose 2. When the slurry delivery hose 2 is in use, a movable sleeve 4 is threadedly connected to the fixed sleeve 3. When the movable sleeve 4 is rotated to a desired position, the rotation of the movable sleeve 4 is limited by a limiting member to fix the position of the movable sleeve 4. When the position of the slurry delivery hose 2 needs to be moved, it can be moved by means of handles 5 provided on both sides of the movable sleeve 4, thereby avoiding a situation in which the hands slip due to direct pushing on the pipe wall.

[0023] Specifically, a first thread 6 is formed at the bottom of the fixed sleeve 3 , and a second thread 7 is formed on the inner wall of the movable sleeve 4 . The first thread 6 and the second thread 7 are meshed with each other.

[0024] Specifically, the limiting member includes limiting grooves 8 symmetrically opened on both sides of the fixed sleeve 3, and first through holes symmetrically opened on both sides of the movable sleeve 4. A limiting rod 9 is inserted and connected in the middle of the first through hole, and one end of the limiting rod 9 is inserted and connected to the inside of the limiting groove 8. A movable part for moving the position of the limiting rod 9 is provided on one side of the limiting rod 9.

[0025] It should be noted that the limit slot 8 is provided in the shape of a long strip, the limit rod 9 is provided in the shape of a cylinder, and the width of the limit slot 8 is greater than the width of the limit rod 9, so that the limit rod 9 can be inserted into the limit slot 8. When the limit rod 9 is inserted into the limit slot 8, the limit rod 9 cannot move in the direction of the inner wall on both sides of the limit slot 8 due to the restriction of the limit slot 8, thereby realizing the restriction of the limit rod 9, so that the movable sleeve 4 set in the middle of the limit rod 9 cannot rotate

[0026] Specifically, the moving part includes a pushing block 12 fixedly connected to the other end of the limiting rod 9 .

[0027] Specifically, the moving part further includes a connecting block 10 sleeved on the middle of the limiting rod 9 , a spring 11 is fixedly connected to one side of the connecting block 10 , and the limiting rod 9 is inserted and connected to the middle of the spring 11 .

[0028] Specifically, one end of the movable sleeve 4 is fixedly connected to the connecting sleeve 13 , the connecting block 10 is slidably inserted into the interior of the connecting sleeve 13 , and one end of the spring 11 away from the connecting block 10 is fixedly connected to the inner wall of one side of the connecting sleeve 13 .

[0029] It should be noted that the spring 11 is used to push the connection block 10 to the side away from the spring 11 , so that one end of the limit rod 9 is pushed to the side away from the first through hole through the push of the spring 11 .

[0030] Further, when it is necessary to thread the movable sleeve 4 onto the outer wall of the fixed sleeve 3, the top of the movable sleeve 4 is inserted into the bottom of the fixed sleeve 3, and one end of the limit rod 9 is pulled into the first through hole by the pushing block 12, and then the movable sleeve 4 is rotated so that it is threadedly connected to the bottom of the fixed sleeve 3, and the pulling on the limit rod 9 is released. Through the push of the spring 11, the limit rod 9 drives one end to fit the outer wall of the fixed sleeve 3, and the movable sleeve 4 continues to be rotated. When the limit rod 9 is rotated to one side of the limit groove 8 opened on the fixed sleeve 3, through the push of the spring 11, one end of the limit rod 9 is inserted into the limit slot. When one end of the limit rod 9 is inserted into the limit slot 8, the movable sleeve 4 cannot be rotated, and the position of the movable sleeve 4 is fixed.

[0031] Specifically, a second through hole is formed on the inner wall of one side of the connecting sleeve 13, and the limiting rod 9 is inserted and connected inside the second through hole.

[0032] It should be noted that the two ends of the limit rod 9 are respectively inserted into the first through hole and the second through hole opened on the movable sleeve 4 and the connecting sleeve 13, and the heights of the two through holes are consistent, so that the moving direction of the limit rod 9 is limited by the two through holes, so that the moving direction of the limit rod 9 is the direction of the two through holes. When one end of the limit rod 9 is inserted into the limit groove 8, when the movable sleeve 4 needs to rotate, it cannot rotate due to the restriction of the limit groove 8.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
