Description

Technical Field

[0001] This invention relates to a concrete conveying method, system, device, and readable storage medium for a concrete conveyor truck, belonging to the field of engineering machinery technology. Background Technology

[0002] In the field of concrete construction for water conservancy and hydropower, the construction of large-volume concrete is usually characterized by low concrete slump, high gradation, and high construction quality requirements. In order to improve the construction quality and production efficiency, telescopic belt conveyor vehicles are often used.

[0003] Telescopic belt conveyors have significant advantages in conveying low-slump, high-grade concrete, but due to their lower level of automation, the following problems may occur during construction:

[0004] 1. During concrete conveying, issues such as belt misalignment, concrete accumulation, backflow, and blockage may occur. These problems can lead to concrete loss, construction termination, and in severe cases, equipment overturning. Concrete blockage in the tail hose, in particular, requires serious attention. The tail hose, typically 3-5 meters long, is an effective measure to reduce aggregate segregation in concrete. Low concrete slump, high gradation, or excessive belt speed can all cause blockage in the tail hose. If not detected promptly, concrete can accumulate at the end of the main conveyor or even the entire main conveyor, leading to bending of the main conveyor boom or even equipment overturning.

[0005] 2. The equipment's working efficiency depends on the operator's skill level, and there is a lack of intelligent control methods for real-time monitoring of conveyor belt speed, tail hose weight, etc.

[0006] To address the aforementioned technical deficiencies, some existing technologies monitor the hopper operation in real time using monitoring probes, positioning sensor modules, and early warning modules. However, the poor monitoring sensitivity leads to system misjudgments. Other existing technologies combine multiple monitoring devices such as video monitoring, weight monitoring, and speed monitoring to monitor the operation screen, tail hose weight, and conveyor belt speed in real time. However, these technologies still cannot guarantee equipment efficiency and thus cannot provide effective preventative measures. Summary of the Invention

[0007] The purpose of this invention is to provide a concrete conveying method, system, device, and readable storage medium for a concrete conveyor truck. It adopts multiple safety construction measures. First, it controls the safe range of the main conveyor boom pitch angle based on the main conveyor boom pitch angle. Then, it carries out the conveying work within the safe range of the main conveyor boom. Finally, it combines the real-time weight of the tail hose to realize adaptive adjustment of the conveyor belt speed, which can cope with various situations such as concrete blockage and poor conveying efficiency.

[0008] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution.

[0009] A method for conveying concrete using a concrete conveyor truck, comprising:

[0010] Obtain the pitch angle of the main conveyor boom;

[0011] The main conveyor boom is judged to be within the safe range of the tail hose based on the comparison between the preset safe range of the tail hose and the pitch angle of the main conveyor boom.

[0012] If the tail hose safety range is met, the main conveyor belt will be started at the default minimum speed, and the tail hose weight value will be obtained in real time.

[0013] Determine whether the main conveyor belt needs to be accelerated based on the comparison between the preset tail hose weight range and the tail hose weight value.

[0014] The presence of a blockage in the tail hose is determined by comparing its weight with a preset weight alarm threshold.

[0015] If a blockage occurs, stop the main conveyor belt.

[0016] Optional methods for presetting the tail hose safety range and tail hose weight range include:

[0017] Slump tests were conducted on different types of concrete delivered, and the slump and gradation information of different concretes were recorded.

[0018] Based on the vehicle design specifications, the slump, gradation information and main conveyor boom pitch angle information of different types of concrete are calculated to obtain the safety range and weight range of the tail hose associated with different concrete types, and stored as the pre-set information of the conveyor vehicle.

[0019] After the conveyor controller obtains the type of concrete being conveyed, it automatically loads the safety range and weight range of the tail hose associated with the concrete.

[0020] Optionally, the determination of whether the main conveyor boom is within the safe range of the tail hose can be based on a comparison between the preset safe range of the tail hose and the pitch angle of the main conveyor boom, including:

[0021] If the pitch angle of the main conveyor boom reaches or exceeds the preset safety range of the tail hose, a main conveyor boom adjustment command is generated to control the pitch angle of the main conveyor boom to be adjusted to the safety range of the tail hose.

[0022] If the pitch angle of the main conveyor boom is within the preset safe range of the tail hose, then the preset weight range of the tail hose is used to control the conveying efficiency of the main conveyor belt.

[0023] Optionally, the main conveyor belt may need to be accelerated based on a comparison between a preset tail hose weight range and the tail hose weight value, including:

[0024] If the weight of the tail hose does not reach the preset tail hose weight range, a conveyor belt acceleration command is generated to control the conveyor belt to accelerate the conveying, so that the real-time weight of the material conveyed by the conveyor belt to the tail hose remains within the preset tail hose weight range.

[0025] If the weight of the tail hose is within the preset tail hose weight range, the conveyor belt speed will not be adjusted.

[0026] If the weight of the tail hose exceeds the preset weight range, the system will determine whether the tail hose is blocked based on the comparison between the tail hose weight and the preset weight alarm threshold.

[0027] Optionally, the presence of a blockage in the tail hose can be determined by comparing its weight with a preset weight alarm threshold, including:

[0028] If the weight of the tail hose reaches or exceeds the preset weight alarm threshold, a blockage is detected, and a conveyor belt stop command is generated.

[0029] If the weight of the tail hose is less than the preset weight alarm threshold, there is no blockage. A conveyor belt speed adjustment command is generated to control the conveyor belt speed, so that the real-time weight of the material conveyed by the conveyor belt to the tail hose remains within the preset tail hose weight range.

[0030] A conveying device suitable for concrete conveyor trucks, comprising:

[0031] Data acquisition module, boom safety assessment module, tail hose weight analysis module, and belt conveyor control module;

[0032] The data acquisition module is used to obtain the main conveyor boom pitch angle, tail hose weight, and conveyor belt speed.

[0033] The boom safety assessment module is used to determine whether the main conveyor boom is within the safe range of the tail hose based on the comparison between the preset tail hose safety range and the main conveyor boom pitch angle.

[0034] The tail hose weight analysis module is used to start the main conveyor belt at the default minimum speed if the tail hose safety range is met, and to obtain the tail hose weight value in real time; and to determine whether the main conveyor belt needs to be accelerated based on the comparison result between the preset tail hose weight range and the tail hose weight value.

[0035] The belt conveyor control module is used to determine whether the tail hose is blocked based on the comparison between the tail hose weight value and the preset weight alarm threshold.

[0036] If a blockage occurs, stop the main conveyor belt.

[0037] Optionally, an alarm module may also be included, which generates an alarm message after the main conveyor belt is stopped to prompt staff to resolve the blockage problem.

[0038] A conveying system suitable for concrete trucks, comprising:

[0039] Tail hose weight sensor, main conveyor boom angle sensor, speed sensor and controller;

[0040] The tail hose weight sensor is used to collect the tail hose weight in real time.

[0041] The main conveyor boom angle sensor is used to collect the pitch angle of the main conveyor boom in real time.

[0042] The controller performs the steps of the above method.

[0043] Optionally, the controller is also connected to the input device of the central control platform for recording the input concrete type and editing preset information.

[0044] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-described method.

[0045] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0046] 1. The method of the present invention has multiple safety construction measures. First, the safe range of the main conveyor boom pitch angle is controlled according to the main conveyor boom pitch angle. The conveying work is carried out within the safe range of the main conveyor boom. Then, the conveyor belt speed is adaptively adjusted by combining the real-time weight of the tail hose. This can cope with various situations such as concrete blockage and poor conveying efficiency.

[0047] 2. By comparing the real-time weight of the tail hose with its weight range, when the real-time weight of the tail hose is outside the weight range and less than the minimum value, the system controls the conveyor belt to slowly increase its speed until the real-time weight of the tail hose is within the weight range. This intelligent material conveying system ensures both safe conveying of concrete and maximum working efficiency of the equipment when conveying concrete.

[0048] 3. When the real-time weight of the tail hose exceeds the tail hose weight range, the system will further compare the real-time weight with the tail hose weight alarm threshold. When the real-time weight reaches or exceeds the tail hose weight alarm threshold, the system will control the conveyor belt to stop running. When the real-time weight is less than the tail hose weight alarm threshold, the system will control the conveyor belt to decelerate until the real-time weight of the tail hose is within the safe range.

[0049] 4. By analyzing and processing the signals from the angle sensor, speed sensor, and weight sensor, the pitch angle of the main conveyor boom, the running speed of the main conveyor belt, and the real-time weight of the tail hose are obtained. The interaction of the monitored values ​​serves the intelligent material conveying system and the intelligent alarm system. Attached Figure Description

[0056] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example

[0057] This embodiment provides a conveying system suitable for concrete trucks, such as... Figure 1 and Figure 2 The system includes: a main conveyor boom 1, a conveyor belt 2, and a tail hose 3. A weight sensor for the tail hose 3 is installed at the tail hose 3, an angle sensor for the main conveyor boom 1 is installed at the main conveyor boom 1, and a speed sensor is installed on the power mechanism of the conveyor belt 2. The speed sensor, the weight sensor for the tail hose 3, and the angle sensor for the main conveyor boom 1 are all connected to the controller.

[0058] The tail hose 3 weight sensor is used to collect the weight value of the tail hose 3 in real time.

[0059] The angle sensor of the main conveyor boom 1 is used to collect the pitch angle of the main conveyor boom 1 in real time;

[0060] The controller performs the steps of the following delivery method.

[0061] The controller is also connected to the input device of the central control platform to record the input concrete type and edit preset information.

[0062] In this embodiment, the interaction method of the input device of the central control platform is as follows:

[0063] Step 1: Input the tail hose weight alarm threshold on the central control platform.

[0064] Step 2: Based on different concrete slump and gradation information, set the safety range of the tail hose on the central control platform. The safety range of the tail hose is the safety range of the pitch angle of the main conveyor boom 1 when conveying concrete.

[0065] Step 3: Based on the concrete slump, gradation, and main conveyor boom 1 pitch angle information, preset the tail hose weight range on the central control platform, or the system automatically records the tail hose weight range corresponding to the concrete slump, gradation, and main conveyor boom 1 pitch angle during equipment operation. Manual input has higher priority than automatic system recording. A series of tail hose weight ranges are generated through manual input or automatic system recording. Each set of tail hose weight ranges corresponds to a set of concrete slump, gradation, and main conveyor boom 1 pitch angle values ​​or ranges.

[0066] Step 4: Position the vehicle-mounted telescopic belt conveyor according to the pouring hopper location, and deploy the equipment outriggers and the telescopic boom of the main conveyor. The pitch angle of the main conveyor is collected by the angle sensor and transmitted back to the central control platform.

[0067] Step 5: Input the slump and gradation information of the concrete to be conveyed into the central control platform. The system will automatically generate the safe range of the tail hose. The system will compare the real-time angle of the main conveyor boom 1 with the safe range of the tail hose. If the real-time angle is within the safe range, proceed to the next step. If the real-time angle is not within the safe range, the system will automatically adjust the pitch angle of the main conveyor boom 1 to the safe range and proceed to the next step.

[0068] Step 6: Based on the concrete slump, gradation, and the pitch angle of the main conveyor boom 1, automatically generate the weight range of the tail hose. When the main conveyor belt 2 is started, it runs at the lowest speed by default.

[0069] Step 7: The weight sensor transmits the detected signal to the central control platform in real time. The central control platform analyzes and processes the sensor signal to generate the real-time weight value of the tail hose 3. The real-time weight value of the tail hose 3 is compared with the weight range of the tail hose. When the real-time weight value is not within the weight range of the tail hose and is less than the minimum weight value, the system controls the conveyor belt 2 to slowly increase its speed until the real-time weight value of the tail hose 3 is within the weight range of the tail hose. At this time, the conveyor belt 2 runs at the current speed at a constant speed.

[0070] Step 8: When the real-time weight of the tail hose 3 is greater than the tail hose weight range, the real-time weight needs to be further compared with the tail hose weight alarm threshold. When the real-time weight reaches or exceeds the tail hose weight alarm threshold, the system controls the conveyor belt 2 to stop running; when the real-time weight is less than the tail hose weight alarm threshold, the system controls the conveyor belt 2 to decelerate until the real-time weight of the tail hose 3 is within the tail hose weight range, at which point the conveyor belt 2 runs at the current speed at a constant speed. Example

[0071] This embodiment provides a conveying method suitable for concrete conveying trucks, such as... Figure 3 and Figure 4 The following are included:

[0072] Obtain the pitch angle of the main conveyor boom 1;

[0073] Determine whether the main conveyor boom 1 is within the safe range of the tail hose based on the comparison between the preset safe range of the tail hose and the pitch angle of the main conveyor boom 1.

[0074] If the tail hose safety range is met, the main conveyor belt 2 will be started at the default minimum speed, and the weight value of the tail hose 3 will be obtained in real time.

[0075] Determine whether the main conveyor belt 2 needs to be accelerated based on the comparison between the preset tail hose weight range and the tail hose 3 weight value;

[0076] The presence of a blockage in the tail hose 3 is determined by comparing its weight with the preset tail hose weight alarm threshold.

[0077] If a blockage occurs, stop the main conveyor belt 2.

[0078] Optional methods for presetting the tail hose safety range and tail hose weight range include:

[0079] Slump tests were conducted on different types of concrete delivered, and the slump and gradation information of different concretes were recorded.

[0080] Based on the vehicle design specifications, the slump, gradation information and the pitch angle information of the main conveyor boom 1 of different concrete types are calculated to obtain the safety range and weight range of the tail hose associated with different concrete types, and the information is stored as the pre-set information of the conveyor vehicle.

[0081] After the conveyor controller obtains the type of concrete being conveyed, it automatically loads the safety range and weight range of the tail hose associated with the concrete.

[0082] Optionally, the determination of whether the main conveyor boom 1 is within the safe range of the tail hose is based on a comparison between the preset safe range of the tail hose and the pitch angle of the main conveyor boom 1, including:

[0083] If the pitch angle of the main conveyor boom 1 reaches or exceeds the preset safety range of the tail hose, an adjustment command for the main conveyor boom 1 is generated to control the pitch angle of the main conveyor boom 1 to be adjusted to the safety range of the tail hose.

[0084] If the pitch angle of the main conveyor boom 1 is within the preset safe range of the tail hose, then the preset weight range of the tail hose is used to control the conveying efficiency of the main conveyor belt 2.

[0085] Optionally, the main conveyor belt 2 can be accelerated based on a comparison between the preset tail hose weight range and the tail hose 3 weight value, including:

[0086] If the weight of the tail hose 3 does not reach the preset tail hose weight range, an acceleration command for the conveyor belt 2 is generated to control the conveyor belt 2 to accelerate the conveying, so that the real-time weight of the material conveyed by the conveyor belt 2 to the tail hose 3 remains within the preset tail hose weight range.

[0087] If the weight of tail hose 3 is within the preset tail hose weight range, the speed of conveyor belt 2 will not be adjusted.

[0088] If the weight of tail hose 3 exceeds the preset tail hose weight range, the tail hose 3 is judged to be blocked based on the comparison between the weight of tail hose 3 and the preset tail hose weight alarm threshold.

[0089] Optionally, the presence of a blockage in the tail hose 3 can be determined by comparing its weight with a preset tail hose weight alarm threshold, including:

[0090] If the weight of tail hose 3 reaches or exceeds the preset tail hose weight alarm threshold, there is a blockage, and a stop command for conveyor belt 2 is generated.

[0091] If the weight of the tail hose 3 is less than the preset tail hose weight alarm threshold, there is no blockage. A speed adjustment command for the conveyor belt 2 is generated to control the conveying speed of the conveyor belt 2, so that the real-time weight of the material conveyed by the conveyor belt 2 to the tail hose 3 is kept within the preset tail hose weight range. Example

[0092] This embodiment provides a conveying device suitable for concrete trucks, such as... Figure 5 The following are included:

[0093] Data acquisition module, boom safety assessment module, tail hose weight analysis module, and belt conveyor control module;

[0094] The data acquisition module is used to obtain the pitch angle of the main conveyor boom 1, the weight value of the tail hose 3, and the speed of the conveyor belt 2.

[0095] The boom safety assessment module is used to determine whether the main conveyor boom 1 is within the safe range of the tail hose based on the comparison between the preset tail hose safety range and the pitch angle of the main conveyor boom 1.

[0096] The tail hose 3 weight analysis module is used to start the main conveyor belt 2 at the default minimum speed if the tail hose safety range is met, and to obtain the tail hose 3 weight value in real time; and to determine whether the main conveyor belt 2 needs to be accelerated based on the comparison result between the preset tail hose weight range and the tail hose 3 weight value.

[0097] The belt conveyor control module is used to determine whether the tail hose 3 is blocked based on the comparison between the weight value of the tail hose 3 and the preset tail hose weight alarm threshold.

[0098] If a blockage occurs, stop the main conveyor belt 2.

[0099] It also includes an alarm module, which generates an alarm message after the main conveyor belt 2 is stopped, prompting staff to resolve the blockage problem. Example

[0100] This embodiment provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the following method:

[0101] Obtain the pitch angle of the main conveyor boom 1;

[0102] Determine whether the main conveyor boom 1 is within the safe range of the tail hose based on the comparison between the preset safe range of the tail hose and the pitch angle of the main conveyor boom 1.

[0107] In summary, the method of this invention incorporates multiple safety measures. First, it controls the safe range of the main conveyor boom 1's pitch angle based on its pitch angle, allowing conveying operations to proceed only within this safe range. Then, it adaptively adjusts the conveyor belt 2's speed by considering the real-time weight of the tail hose 3, addressing various issues such as concrete blockage and poor conveying efficiency. By comparing the real-time weight of the tail hose 3 with its weight range, when the real-time weight of the tail hose 3 is outside its range and below the minimum safe value, the system controls the conveyor belt 2 to slowly increase its speed until the real-time weight of the tail hose 3 falls within its range. This intelligent material conveying system ensures both safe concrete conveying and maximum operational efficiency during concrete transport. When the real-time weight of the tail hose 3 exceeds the tail hose weight range, the system will further compare the real-time weight with the tail hose weight alarm threshold. When the real-time weight reaches or exceeds the tail hose weight alarm threshold, the system controls the conveyor belt 2 to stop running; when the real-time weight is less than the tail hose weight alarm threshold, the system controls the conveyor belt 2 to decelerate until the real-time weight of the tail hose 3 is within the tail hose weight range. By analyzing and processing the signals from the angle sensor, speed sensor, and weight sensor, the pitch angle of the main conveyor boom 1, the running speed of the main conveyor belt 2, and the real-time weight of the tail hose 3 are obtained respectively. The coordination of the monitored values ​​serves the intelligent material conveying system and the intelligent alarm system.
