[0002] Concrete delivery hose fixed-point pouring means that concrete, mud and other construction materials are transported to the designated pouring site by positive or negative pressure in an ambient temperature of -30℃~+70℃ through a specific rubber hose, and pouring operations are carried out.
[0003] There are the following problems in the construction process of traditional concrete fixed-point pouring projects:
[0004] First, when using a hose to transport concrete, the concrete is sprayed directly downward from the storage tank or vehicle, and the pipeline pressure is too high, causing the hose to swing left and right due to stress during the spraying process, making it difficult to accurately control the spraying direction and concrete flow rate.
[0005] Secondly, since the hose cannot accurately spray concrete to the predetermined location, 2-3 workers are usually required to assist the hose in delivering concrete to ensure that the concrete can accurately reach the target area. This not only increases labor costs, but also brings certain safety risks when pouring high-rise buildings and other buildings, as workers work in the edge areas. Utility Model Content

[0024] 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 of 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.
[0025] like Figures 1 to 4 As shown, a concrete delivery hose fixed-point pouring auxiliary equipment includes a connector 1 fixedly connected to the arm of a pump truck, a hose 2, a mounting head 3, an adjustment rod 4 and a fixing ring 5. The top of the mounting head 3 is connected to the connector 1 by bolts and nuts to ensure the stability and sealing of the connection. The bottom of the mounting head 3 is connected to the hose 2 by an annular buckle to effectively prevent slurry leakage and ensure the smooth progress of the pouring process.
[0026] The edge of the connector 1 is circumferentially provided with a plurality of first matching holes 11, the fixing ring 5 is circumferentially provided with a plurality of second matching holes 51, the top and bottom ends of the adjusting rod 4 are both provided with threads, and the first matching holes 11 and the second matching holes 51 are provided with first nuts that are threadedly matched with the adjusting rod 4. The first nuts are used to fix the mounting head 3 and the fixing ring 5 with the adjusting rod 4. This connection method can resist the huge stress generated when the pump truck sprays concrete, and ensure the stability of the mounting head 3, the fixing ring 5 and the adjusting rod 4 under high pressure.
[0027] The inner diameter of the fixing ring 5 is slightly larger than the diameter of the hose 2. The hose 2 passes through the fixing ring 5, and the fixing ring 5 provides stable support for the hose 2. The distance between the mounting head 3 and the fixing ring 5 is adjusted by the adjusting rod 4, so as to adjust the position of the fixing ring 5 for fixing and supporting the hose 2, so that the hose 2 at the predetermined position can remain stable and not shake, so that the hose 2 can accurately spray concrete to the predetermined position. At the same time, by improving the stability and casting accuracy of the hose 2, the need for manual intervention is reduced, and the labor cost is reduced. In addition, due to the enhanced stability of the hose 2, the need for workers to work in the marginal areas is reduced, and the safety risks during the casting of high-rise buildings are reduced.
[0028] refer to Figure 3 and Figure 4 As shown, in some specific embodiments, in order to improve the flexibility and adjustment accuracy of the adjustment rod 4, the adjustment rod 4 includes a first rod body 41, a second rod body 42, a locking rod 43 and a locking sleeve 44. The top end of the first rod body 41 and the bottom end of the second rod body 42 are both provided with threads, and the end of the first matching hole 11 is provided with a second nut that matches the thread of the first rod body, and the end of the second matching hole 51 is provided with a third nut that matches the thread of the second rod body 42. The first rod body 41 is fixedly connected to the connector 1 through the second nut, and the second rod body 42 is fixedly connected to the fixing ring 5 through the third nut to ensure the stability and sealing of the connection.
[0029] Specifically, a slide groove 45 is provided inside the first rod body 41, and the top end of the second rod body 42 is slidably connected to the slide groove 45. By sliding the second rod body 42 in the first rod body 41, the distance between the mounting head 3 and the fixing ring 5 is changed, and then the position of the fixing ring 5 for fixing and supporting the hose 2 is adjusted. A positioning hole connected to the slide groove 45 is provided at the bottom end of the first rod body 41, and the locking rod 43 passes through the positioning hole. The second rod body 42 is provided with a plurality of longitudinally equidistantly arranged adjustment holes 46, and the adjustment holes 46 cooperate with the locking rod 43. Through a plurality of longitudinally equidistantly arranged adjustment holes 46, more precise adjustment and locking can be achieved, ensuring that the hose 2 can accurately spray concrete to a predetermined position.
[0030] Specifically, the locking rod 43 is arranged in the positioning hole and the adjustment hole 46. When the second rod body 42 slides to a suitable position, the locking rod 43 is inserted into the positioning hole and the corresponding adjustment hole 46, thereby locking the relative position of the first rod body 41 and the second rod body 42 to ensure stability after adjustment.
[0031] Specifically, the locking sleeve 44 is fixedly sleeved at the end of the positioning hole, the outer side of the locking rod 43 is provided with a thread, the locking sleeve 44 is provided with a locking hole that is threadedly matched with the locking rod 43, and the locking hole is connected with the positioning hole. Specifically, when the second rod body 42 slides to a suitable position, the locking rod 43 is inserted into the positioning hole, the corresponding adjustment hole 46 and the locking hole, and the locking rod 43 is rotated to fix the locking rod 43 in the locking hole, thereby further locking the relative position of the first rod body 41 and the second rod body 42 to ensure stability after adjustment.
[0032] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:
[0033] When it is necessary to adjust the stability of the hose 2 at the predetermined position, slide the second rod 42 in the first rod 41 to change the distance between the mounting head 3 and the fixing ring 5. When the second rod 42 slides to a suitable position, insert the locking rod 43 into the positioning hole and the corresponding adjustment hole 46, and rotate the locking sleeve 44 to fix the locking rod 43 in the locking hole, thereby locking the relative position of the first rod 41 and the second rod 42. Through a plurality of longitudinally equidistantly arranged adjustment holes 46, more precise adjustment and locking can be achieved to ensure that the hose 2 can accurately spray concrete to the predetermined position. The fixing ring 5 provides stable support for the hose 2 to ensure that the hose 2 remains stable and does not shake at the predetermined position.
[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
