Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, in particular to an underwater concrete pouring tool. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are put into a mold to form a predetermined shape. Now many concrete projects need to be carried out below the water line, especially the construction of embankment foot or sea embankment foot and underwater concrete construction in other fields. In order to ensure the quality of concrete pouring, large excavation must be carried out and cofferdam construction must be adopted. The cofferdam needs to be well waterproofed, and the formwork must be erected in a dry working site. Concrete pouring can be carried out after the formwork engineering.

[0003] The existing public patent (publication number CN203113343U) discloses an underwater concrete pouring device for large-diameter bored piles, including a main hopper, a concrete conduit is provided at the bottom of the main hopper, and the bottom pipe mouth of the concrete conduit is located at the bottom of the bored pile hole; an auxiliary hopper is provided on one side of the hole mouth of the bored pile hole. The utility model arranges an auxiliary hopper next to the main hopper. When the concrete in the main hopper cannot meet the amount of concrete required for underwater pouring of bored piles with large diameter holes, the auxiliary hopper is used to replenish it, ensuring that the concrete burial depth of the conduit is greater than 1.5m during the first pouring. Prevent muddy water in the bored pile hole from entering the conduit from the bottom of the conduit, improve construction quality, reduce construction costs and shorten construction period. The utility model has the advantages of simple manufacture and installation, low investment cost and convenient use.

[0004] In the above pouring process, due to the lack of a mixing device, the concrete in the cast-in-place pile may have uneven dispersion of larger particles and a large number of mixed bubbles. To this end, we provide an underwater concrete pouring tool to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses an underwater concrete pouring tool, comprising a pouring end connected to a concrete pouring machine arm; the pouring end comprises a mounting plate, a limiting pipe arranged at an edge of the mounting plate, a pouring pipe passing through the limiting pipe, a conveying pipe connected to a plurality of pouring pipes, a motor fixed at a middle position of a side surface of the mounting plate, a support rod connected to an output shaft of the motor, a positioning ring fixed to the bottom of the support rod, a stirring rod movably arranged on a peripheral side of the positioning ring, a support arm movably connected to a middle position of the stirring rod, and a sleeve ring movably connected to an upper end of the support arm.

[0007] The utility model is further configured such that the end of the support rod is sleeved in a bearing seat embedded in the middle of the mounting plate, and the length of the support rod is greater than the length of the casting pipe arranged below the mounting plate.

[0008] The utility model is further configured that the collar is sleeved on the outside of the support rod, and the collar is fixed to the outside of the support rod via a knob.

[0011] The utility model is further configured that the support rod, the support arm and the stirring rod form a three-link structure, and the angle between the support arm and the support rod is in the range of 0-60°.

[0012] The utility model has the following beneficial effects:

[0013] The utility model assists in the unloading of concrete by arranging a pouring end head. The stirring rod arranged in the pouring end head can realize angle adjustment under the moving drive of the support arm to meet the concrete mixing needs in different spaces, and also facilitates the unfolding and storage of its own structure. When the motor is started, the torsion force of its output shaft is transmitted to the stirring rod through the support rod. During the rotation process, the stirring rod stirs the concrete poured in the foundation pile, reduces the mixing of bubbles, and makes the large particles in the concrete relatively evenly distributed.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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.

[0022] Example

[0023] See also Figure 1-3 The utility model is an underwater concrete pouring tool, comprising a pouring end 1 connected to a concrete pouring machine arm; the pouring end 1 comprises a mounting plate 11, a limiting pipe 12 arranged at an edge of the mounting plate 11, a pouring pipe 14 passing through the limiting pipe 12, a conveying pipe 15 connected to a plurality of pouring pipes 14, a motor 13 fixed to the middle position of the upper side of the mounting plate 11, a support rod 16 connected to the output shaft of the motor 13, a positioning ring 110 fixed to the bottom of the support rod 16, a stirring rod 19 movably arranged on the periphery of the positioning ring 110, a support arm 18 movably connected to the middle position of the stirring rod 19, and a sleeve ring 17 movably connected to the upper end of the support arm 18.

[0024] Specifically, in the underwater concrete pouring tool involved in the present application, a pouring end 1 is provided to assist in the unloading of concrete. The stirring rod 19 provided in the pouring end 1 can adjust its angle under the moving drive of the support arm 18 to meet the concrete mixing needs in different spaces, and it is also convenient for the deployment and storage of its own structure. When the motor 13 is started, the torque of its output shaft is transmitted to the stirring rod 19 through the support rod 16. During the rotation process, the stirring rod 19 stirs the concrete poured in the foundation pile, reduces the mixing of bubbles, and makes the large particles in the concrete relatively evenly distributed.

[0025] Furthermore, the end of the support rod 16 is sleeved in the bearing seat embedded in the middle of the mounting plate 11, the length of the support rod 16 is greater than the length of the casting tube 14 arranged below the mounting plate 11, the ring 17 is sleeved on the outside of the support rod 16, and the ring 17 is fixed to the outside of the support rod 16 via a knob.

[0026] Specifically, the bearing seat embedded in the middle of the mounting plate 11 is used to assist the rotational positioning of the support rod 16. To prevent the casting tube 14 from interfering with the rotating support arm 18 and the stirring rod 19, the length of the support rod 16 needs to be greater than the length of the casting tube 14, and it is necessary to ensure that the casting tube 14 does not hinder the support arm 18 and the stirring rod 19 during the storage and deployment process.

[0027] A plurality of stirring rods 19 are arranged in an umbrella shape, and the stirring rods 19 are located below the pouring pipe 14. The support rod 16, the support arm 18 and the stirring rod 19 form a three-link structure, and the angle between the support arm 18 and the support rod 16 ranges from 0° to 60°.

[0028] Specifically, the three-link structure composed of the support rod 16, the support arm 18 and the stirring rod 19, the support arm 18 serves as the dominant structure. The support arm 18 adjusts the angle of the three-link structure as the ring 17 moves, that is, adjusts the expansion degree of the stirring rod 19. When the angle between the support arm 18 and the support rod 16 is 60°, the stirring rod 19 is in the maximum expansion state.

[0029] Furthermore, the delivery pipe 15 is connected to an external concrete pipe, and the mounting plate 11 is connected to an external moving drive.

[0030] Specifically, the pouring end head 1 is used in conjunction with the movement of the concrete pouring machine arm. The concrete pouring machine arm is a relatively mature technology at present. By setting a movable and adjustable arm structure, the installation of the concrete pipe is assisted, thereby realizing the long-distance unloading of concrete. The present application does not make further restrictive descriptions on the specific structure and principle of the concrete pouring machine arm. During the actual working process, the position height of the pouring end head 1 is affected by the drive of the concrete pouring machine arm, and the conveying pipe 15 is used to divert and receive the concrete in the concrete pipe, and divert it into multiple pouring pipes 14.
