[0002] In the field of large-scale component production, the transfer of concrete slurry is a key process. Traditional transfer tanks have a series of problems in this process, mainly due to their design limitations. Current transfer tanks often lack unloading components, which causes concrete slurry to adhere to the inner wall of the tank, requiring frequent cleaning, seriously affecting production efficiency. In addition, due to the lack of support for unloading components, concrete slurry can only be discharged by its own weight, and efficient transfer cannot be achieved, resulting in a waste of energy and time.

[0003] In addition, the valve body and material guide structure of traditional transfer tanks usually adopt a split design, which limits the functions of each component, restricts the flow control of slurry in the tank, and cannot be flexibly adjusted. If all functions are to be realized, more components and complex structures need to be added, which not only increases production costs, but also increases maintenance difficulties.

DETAILED DESCRIPTION

[0032] 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.

[0033] See also Figure 1-6 A concrete transfer tank for large-scale component production includes a mounting bracket 1, a tank body 2, a material discharge assembly, and a material guide valve plate 4. The tank body 2 is fixedly mounted on the mounting bracket 1. An open material discharge port 201 is provided on the top of the tank body 2. A constricted material discharge port 202 is provided on the bottom of the tank body 2. The material discharge assembly is rotatably mounted on the inner side of the tank body 2 and keeps in contact with the inner wall of the tank body 2. The material guide valve plate 4 is rotatably mounted on the mounting bracket 1 and keeps in sealing contact with the material discharge port 202.

[0034] The unloading assembly includes an upper mounting ring 31, a lower mounting ring 32, and spiral blades 33. The upper mounting ring 31 is rotatably mounted on the inner side of the loading port 201, and the lower mounting ring 32 is rotatably mounted at the unloading port 202. Multiple groups of spiral blades 33 distributed in a circular array are fixedly connected between the upper mounting ring 31 and the lower mounting ring 32.

[0035] The drive assembly is also included and is mounted on the tank body 2 . The drive assembly includes a rotating ring seat 51 . The rotating ring seat 51 is rotatably mounted in the tank body 2 and is fixedly connected to the lower mounting ring 32 .

[0036] It also includes an adjusting component mounted on the mounting bracket 1 , and the adjusting component is linked with the material guide valve plate 4 .

[0037] The mounting bracket 1 is formed by assembling and welding angle steels, which can ensure that the tank body 2 is stably installed and supported therein. The tank body 2 is used to contain and transport concrete slurry. The mounting bracket 1, the tank body 2 and the components installed thereon are transported to the casting site of the large concrete component by hoisting, and concrete slurry is added to the component mold.

[0038] In order to ensure the stability of the mounting bracket 1 when it is stationary, an annular cushion 11 is fixed to the bottom of the mounting bracket 1. The annular cushion 11 can be stably fitted with the horizontal ground and the base surface to ensure the stability of the mounting bracket 1, the tank body 2 and the concrete slurry therein.

[0039] For the material discharge assembly, the upper mounting ring 31 and the lower mounting ring 32 are installed at the upper material opening 201 and the lower material opening 202, and can rotate freely along the inner wall in the tank body 2, and the spiral blade 33 acts on the functional component of the material discharge assembly, which is effectively fixed by the upper mounting ring 31 and the lower mounting ring 32 to achieve connection with the driving assembly.

[0040] When the driving component drives the unloading component to operate, the running spiral blades 33 can scrape off the concrete slurry adhering to the inner wall of the tank body 2, and then due to the spiral design, the concrete slurry can be continuously pushed to flow toward the unloading hole, thereby preventing the concrete slurry from accumulating and clogging at the unloading port 202 and affecting its normal transportation effect.

[0041] The material guide valve plate 4 can be driven by the adjustment component to adjust the deflection angle. When the material guide valve plate 4 is in a horizontal posture, the discharge port 202 can be effectively graduated to avoid leakage of concrete slurry from the discharge port 202 during transportation. When the material guide valve plate 4 is flipped to a downward tilted posture, the discharge port 202 is in an open state, and the concrete slurry in the tank body 2 can fall onto the material guide valve plate 4 and be discharged outward along the material guide valve plate 4.

[0042] In order to prevent the concrete slurry from spilling from the outer edge of the material guide valve plate 4 during the feeding process, an upward-turned baffle 41 is provided on the outer edge of the material guide valve plate 4, and no baffle 41 is provided at the downstream end of the material guide valve plate 4, so that the concrete slurry can be discharged from the downstream end of the material guide valve plate 4.

[0043] In order to facilitate the processing and forming of the tank body 2, as well as the disassembly and maintenance of the tank body 2, the following technical solution is provided.

[0044] The tank body 2 includes a tank body section 21, a transition section 22, and a closing section 23 arranged in sequence from top to bottom. The upper and lower ends of the tank body section 21, the upper and lower ends of the transition section 22, and the top of the closing section 23 are all fixedly connected with flanges 24, and two adjacent sets of flanges 24 are fixedly connected by bolt assemblies.

[0045] The tank body section 21 is designed as an open straight cylinder, the top of the transition section 22 is matched with the bottom of the tank body section 21, and the inner diameter of each part of the transition section 22 gradually decreases from top to bottom, and the bottom of the transition section 22 is matched with the small-mouthed closing section 23. The various sections of the tank body 2 are fixed and combined by bolt assemblies, which is convenient for individual processing of the independent components of the tank body 2 and also convenient for disassembly and maintenance.

[0046] Based on the above structure, the feeding port 201 is located at the top of the tank body section 21, and the upper mounting ring 31 is arranged on the inner side of the flange 24 at the top of the tank body section 21. The separate design of the transition section 22 and the closing section 23 facilitates the assembly of the driving assembly at the connection between the two, so that the rotating ring seat 51 in the driving assembly is fixedly connected to the lower mounting ring 32 in the unloading assembly, and the operating rotating ring seat 51 drives the overall operation of the unloading assembly.

[0047] In order to ensure that the rotating ring seat 51 in the driving assembly can be stably installed in the tank body 2, realize the effective connection between the rotating ring seat 51 and the lower mounting ring 32, and avoid leakage of concrete slurry at the connection and assembly point between the rotating ring seat 51 and the tank body 2, the following technical solution is provided.

[0048] An upper assembly ring groove 221 is fixedly connected to the bottom end of the transition section 22, and a lower assembly ring groove 231 that matches and docks with the upper assembly ring groove 221 is fixedly connected to the top of the closing section 23. A positioning ring 232 is fixedly connected to the bottom wall of the lower assembly ring groove 231. The rotating ring seat 51 is rotatably installed between the upper assembly ring groove 221 and the lower assembly ring groove 231, and the rotating ring seat 51 and the inner side wall of the positioning ring 232 maintain a sealing fit. The lower mounting ring 32 is fixedly connected to the inner side wall of the rotating ring seat 51 by a bolt assembly, and the inner wall of the lower mounting ring 32 is flush with the bottom interface of the transition section 22 and the top interface of the closing section 23.

[0049] The setting of the upper assembly ring groove 221 and the lower assembly ring groove 231 can ensure that the rotating ring seat 51 is stably installed therein and can rotate freely. In order to prevent concrete slurry from leaking from the connection between the upper assembly ring groove 221, the lower assembly ring groove 231 and the rotating ring seat 51, a corrosion-resistant high-strength sealing ring can be installed on the outer side wall of the rotating ring seat 51, and the flange 24 at the corresponding position of the closing section 23 and the transition section 22 is arranged on the outer side of the upper assembly ring groove 221 and the lower assembly ring groove 231.

[0050] The setting of the positioning ring 232 can further limit the rotating ring seat 51, ensuring that it drives the lower mounting ring 32 to stably rotate around its own axis. The cross-section of the rotating ring seat 51 is set to be L-shaped, and its transverse section maintains a sealed fit with the inner wall of the upper assembly ring groove 221 to further limit the operating posture of the rotating ring seat 51.

[0051] The inner wall of the rotating ring seat 51 is recessed inward compared to the inner walls of the transition section 22 and the closing section 23, so that the lower mounting ring 32 can be stably assembled in the recessed position, and the inner wall of the lower mounting ring 32 is kept flush with the bottom interface of the transition section 22 and the top interface of the closing section 23, ensuring the stable feeding process of the concrete slurry.

[0052] The provision of the upper assembly ring groove 221 and the lower assembly ring groove 231 can also ensure that other components in the drive assembly are stably assembled therein.

[0053] In order to ensure that the driving assembly can drive the rotating ring seat 51 therein to operate stably and to ensure that the driving assembly is stably assembled in the upper assembly ring groove 221 and the lower assembly ring groove 231, the following technical solution is provided.

[0054] The driving assembly also includes a driving joint 52 and a driving bevel gear 53 and a transmission bevel gear 54 that maintain matching meshing. A connecting shaft 531 is fixedly connected to the axis of the driving bevel gear 53. The connecting shaft 531 is plugged into the side wall of the lower assembly ring groove 231 in a freely rotatable manner. The transmission bevel gear 54 is fixedly connected to the rotating ring seat 51. The driving joint 52 is arranged on the outside of the tank body 2. The connecting shaft 531 and the driving joint 52 are nested and plugged and fixedly combined by a bolt assembly.

[0055] A hexagonal groove 521 is provided at the outer end of the driving joint 52, which can be plugged into the output shaft of the crank or the motor, thereby driving the driving bevel gear 53 to operate, thereby driving the transmission bevel gear 54, the rotating ring seat 51, and the blanking assembly to operate. Since the number of teeth on the driving bevel gear 53 is much smaller than the number of teeth on the transmission bevel gear 54, it has the effect of reducing speed and increasing torque during power transmission, thereby driving the blanking assembly to operate stably.

[0056] When assembling the tank body 2, the blanking assembly and the driving assembly, the following process is followed: first, assemble the driving bevel gear 53 with the connecting shaft 531 to the lower assembly ring groove 231 of the closing section 23, and fix the driving joint 52 on the outer end of the connecting shaft 531; then install the rotating ring seat 51 with the transmission bevel gear 54 into the lower assembly ring groove 231, and make the transmission bevel gear 54 and the driving bevel gear 53 mesh with each other; then assemble the transition section 22, so that the upper assembly ring groove 221 is pressed and tightly covered on the rotating ring seat 51, and the blanking assembly is installed in the transition section 22, so that the lower mounting ring 32 is fixedly combined with the rotating ring seat 51; finally, assemble the tank body section 21, wrap the tank body section 21 with the spiral blade 33 and the upper mounting ring 31, and complete all assembly work.

[0057] In order to ensure that the material guide valve plate 4 is stably assembled on the mounting bracket 1 in a relatively rotating manner, and to ensure that the adjustment component is assembled on the mounting bracket 1 and realizes linkage with the material guide valve plate 4, the following technical solution is provided.

[0058] An assembly frame plate 12 is fixedly connected to the mounting bracket 1 , and an installation shaft 42 is fixedly connected to the bottom of the material guide valve plate 4 . The installation shaft 42 is rotatably mounted in the assembly frame plate 12 .

[0059] The adjusting assembly includes a threaded seat 61, a threaded rod 62, a rotating sleeve 63, and a connecting rod 64. The threaded seat 61 is fixed to the bottom of the mounting bracket 1, the threaded rod 62 is screwed into the threaded seat 61, the rotating sleeve 63 is rotationally connected to the end of the threaded rod 62, and the two ends of the connecting rod 64 are respectively hinged to the rotating sleeve 63 and the material guide valve plate 4.

[0060] The design of the assembly frame plate 12 and the mounting shaft 42 can ensure that the material guide valve plate 4 is stably installed on the mounting bracket 1 in a relatively rotating posture. A handwheel 621 is also fixedly connected to the end of the threaded rod 62 away from the rotating sleeve 63. The handwheel 621 is driven to rotate and drive the threaded rod 62 to rotate in and out of the threaded seat 61, thereby adjusting the position of the rotating sleeve 63, and then driving the material guide valve plate 4 to adjust the flipping posture around the mounting shaft 42 through the connecting rod 64, so as to control the inclination angle of the material guide valve plate 4 and the opening and closing state of the discharge port 202.
