Description

Technical Field

[0001] This utility model relates to the technical field of concrete transport tank cleaning equipment, and in particular to a concrete transport tank cleaning device. Background Technology

[0002] Currently, concrete mixer trucks are indispensable key equipment in modern construction projects, used to transport ready-mixed concrete between mixing plants and construction sites. After each unloading task, a layer of concrete residue inevitably adheres to the inner wall of the mixer truck and the auger blades. If not cleaned effectively in a timely manner, this residue will gradually solidify and harden, not only reducing the effective volume of the tank, increasing the vehicle's weight and fuel consumption, but also affecting the quality of subsequent batches of concrete. Therefore, thoroughly cleaning the mixer truck is a necessary task in daily operations.

[0003] Regarding the aforementioned issues, a common cleaning method exists within the industry. This method typically utilizes a separate high-pressure cleaning system. After the concrete mixer truck parks in the designated cleaning area, on-site personnel operate a forklift to lift the high-pressure cleaning system using the forks. They then carefully aim the spray nozzle at the inside of the mixer truck's opening. Once roughly aligned, the high-pressure water pump is activated, spraying water through the nozzles to flush the inside of the tank.

[0004] However, the aforementioned existing technologies have revealed many shortcomings in practical applications. First, the entire cleaning process relies heavily on the coordinated operation of forklifts, and the introduction of large machinery for precise docking poses a serious safety hazard. The forklift driver's skill level and concentration directly affect the safety of the equipment and personnel. Even a slight mistake could lead to a collision between the cleaning device and the transport tanker, causing costly equipment damage.

[0005] Secondly, this human-machine collaborative method involves a cumbersome operation process and time-consuming preparation, significantly reducing vehicle turnaround efficiency. Finally, relying on forklifts for positioning has very limited adjustment precision, making it difficult for operators to accurately position and stably hold the nozzle at the optimal cleaning location. This results in the water jet failing to effectively cover all corners inside the tank, especially hard-to-reach areas such as the back of the spiral blades, leading to incomplete cleaning and highly inconsistent quality, making it difficult to eradicate the problem of long-term concrete accumulation and caking.

[0006] To address the above issues, a concrete transport tank cleaning device is proposed. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a concrete transport tank cleaning device, which aims to solve the problems of high safety risks, cumbersome operation steps, low work efficiency, and incomplete cleaning effect caused by inaccurate positioning in existing concrete transport tank cleaning methods that rely on forklift operation.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a concrete transport tank cleaning device, including a base, a frame fixedly connected to the top of the base, a crossbeam on the outer side of the frame, a transport tank directly above the frame, a rotating assembly on the outer side of the transport tank for driving the transport tank to rotate, a spraying mechanism on one side of the top of the base, the spraying mechanism including a water tank, a pump on one side of the water tank, the input end of the pump connected to the inside of the water tank via a pipe, a telescopic hose installed at the output end of the pump, and a surrounding water spraying assembly installed at the end of the telescopic hose away from the pump, the surrounding water spraying assembly for cleaning the inside of the transport tank from multiple directions.

[0009] As a further description of the above technical solution:

[0010] The surrounding water spray assembly includes a water storage tray, the interior of which is hollow, the end of the telescopic hose is connected to the interior of the water storage tray, and multiple water spray heads are arranged around the side wall of the water storage tray.

[0011] As a further description of the above technical solution:

[0012] An electric push rod is installed on the top of the cross frame, and the output end of the electric push rod is fixedly connected to the top of the water storage pan.

[0013] As a further description of the above technical solution:

[0014] The outer side of the telescopic hose penetrates the interior of the base frame, and a water inlet pipe is provided on one side of the top of the water storage tank.

[0015] As a further description of the above technical solution:

[0016] The rotating assembly includes a drive motor, the output end of which is connected to a connecting rod via a coupling. A gear is fixedly connected to the end of the connecting rod away from the coupling. A toothed ring is fitted on the outside of the transport tank, and the gear meshes with the toothed ring.

[0017] As a further description of the above technical solution:

[0018] The bottom of the transport tank is provided with a rotating shaft, the top of the base frame is provided with a support plate, the rotating shaft is rotatably connected to the top of the support plate, and the two gears are symmetrically arranged on both sides of the bottom of the gear ring.

[0019] As a further description of the above technical solution:

[0020] A pad is fixedly connected to the right side of the base frame, and the bottom of the drive motor is fixedly connected to the top of the pad.

[0021] As a further description of the above technical solution:

[0022] The two connecting rods are rotatably connected inside the bends on both sides of the support plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, a rotating component enables the transport tank to rotate stably and continuously. Simultaneously, the surrounding water spray component in the spraying mechanism extends into the tank from the opening. This design allows the fixed water spray component to dynamically engage with the rotating inner wall of the tank, ensuring that high-pressure water can reach every corner of the tank interior 360 degrees without any blind spots. The synergistic effect of tank rotation and multi-directional water spraying greatly improves the thoroughness and coverage of cleaning, effectively solving the problem of concrete residue.

[0025] 2. In this invention, by installing an electric push rod on the crossbeam and connecting its output end to the water storage pan, precise control and automated adjustment of the front and rear positions of the surrounding water spray assembly are achieved. Operators can control the extension and retraction of the water spray assembly within the tank via the electric push rod without manually adjusting the nozzle position, thus enabling targeted rinsing of areas at different depths. This reduces the labor intensity and safety risks of manual operation, automates and standardizes the cleaning process, improves work efficiency, and eliminates the need for additional lifting equipment.

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a concrete transport tank cleaning device, the overall structure of which is stably mounted on a base 1. A base frame 3 for supporting the main components is fixedly connected to the top of the base 1. To achieve comprehensive cleaning of the interior of the transport tank 5, a complete rotating assembly 6 is provided on the outside of the transport tank 5. This rotating assembly 6 includes a drive motor 601, which is mounted on top of a pad 301 fixed to the right side of the base frame 3 to ensure stable installation. The output end of the drive motor 601 is connected to a connecting rod 603 via a coupling 602, and the other end of the connecting rod 603 is fixedly connected to a gear 604. A gear ring 605 is fitted on the corresponding position on the outside of the transport tank 5, and the gear ring 605 meshes with the gear 604. To ensure smooth and reliable transmission, preferably, two gears 604 are symmetrically meshed on both sides of the bottom of the gear ring 605. Meanwhile, a rotating shaft is installed at the bottom of the transport tank 5, which is rotatably connected to a support plate on the top of the base frame 3. Two connecting rods 603 are cleverly rotatably connected inside the bends on both sides of the support plate. When the drive motor 601 is started, the power is transmitted to the gear 604 via the coupling 602 and connecting rods 603, thereby driving the gear ring 605 and the entire transport tank 5 to rotate stably. In conjunction with the spraying mechanism 4 extending from the tank opening, the fixed nozzles can form a 360-degree full-coverage flush on the inner wall of the rotating tank, thereby thoroughly removing concrete residue from every corner of the tank.

[0034] Reference Figure 1 , Figure 3 and Figure 4On one side of the top of the base 1, a spraying mechanism 4 is provided, which includes a water storage tank 41 for storing cleaning water, and an inlet pipe 411 for replenishing water. A pump 42 is connected to one side of the water storage tank 41, and the input end of the pump 42 is connected to the inside of the water storage tank 41 through a pipe. A telescopic hose 43 is installed at the output end of the pump 42, and the telescopic hose 43 is arranged to run through the inside of the base frame 3. The end of the hose is connected to the core surrounding water spray assembly 44. The surrounding water spray assembly 44 consists of a hollow water storage tray 441 and multiple water nozzles 442 arranged around its side wall. The water flow is distributed by the water storage tray 441 and then powerfully sprayed out from the multiple water nozzles 442. In order to realize the automatic telescopic positioning of the spraying assembly in the transport tank 5, a crossbeam 2 is provided on the outside of the base frame 3, and an electric push rod 7 is installed on the top of the crossbeam 2. The output end of the electric push rod 7 is directly fixed to the top of the water storage tray 441. During cleaning operations, activating the electric push rod 7 pushes or pulls the water storage tray 441, causing the entire surrounding water spray assembly 44 to extend or retract along the axial direction of the transport tank 5. This allows for precise and controlled rinsing of areas at different depths within the tank. It replaces tedious and dangerous manual operations, automating and standardizing the cleaning process, and significantly improving operational efficiency and safety.

[0035] Working principle: First, the transport tank 5 to be cleaned is placed on the base frame 3 fixed to the top of the base 1. The bottom shaft of the tank is rotatably connected to the support plate at the top of the base frame 3. After cleaning begins, the drive motor 601 fixed on the right side pad 301 of the base frame 3 starts. Its power is transmitted to the connecting rod 603 through the coupling 602. The connecting rod 603 drives the gear 604 at the end to rotate. Since the gear 604 meshes with the gear ring 605 sleeved on the outside of the transport tank 5, it drives the entire transport tank 5 to rotate around its central axis. While the transport tank 5 is rotating, the spraying mechanism 4 starts to operate. The pump 42 draws water from the water storage tank 41, which can be replenished through the water inlet pipe 411. After pressurization, the water is delivered to the hollow water storage pan 441 surrounding the spraying assembly 44 through the telescopic hose 43 that runs through the base frame 3. Then, the water is sprayed into the tank through multiple spray heads 442 arranged around the side wall of the water storage pan 441. At the same time, the electric push rod 7 installed on the crossbeam 2 has its output end fixedly connected to the top of the water storage pan 441. Through its own telescopic movement, it pushes or pulls the entire surrounding water spray assembly 44 to move up and down along its axis inside the transport tank 5, completing the comprehensive cleaning of the tank interior.

[0036] 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.
