Description

Technical Field

[0001] This invention belongs to the field of concrete conveying technology, specifically relating to a torpedo-type concrete conveying control system that can be precisely adjusted. Background Technology

[0002] Torpedo canisters are mainly used for concrete conveying. Their function is to transport the mixed material to the placement location and other destinations, and then tilt the torpedo canister to dump the concrete.

[0003] Because the material being transported is mixed concrete, which is prone to setting and hardening, existing torpedo tank cylinders are prone to concrete adhering to their inner walls, resulting in incomplete dumping. To address this, Chinese Patent CN219132764U provides a torpedo tank-type concrete conveying device, belonging to the field of concrete conveying equipment. Its technical solution includes a traveling frame, a concrete torpedo tank mounted on the traveling frame, and an inner wall cleaning mechanism disposed inside the concrete torpedo tank body. A left mounting frame and a right mounting frame are symmetrically arranged at the bottom of the left and right sides of the traveling frame, with the concrete torpedo tank rotatably mounted between the left and right mounting frames. The inner wall cleaning mechanism includes a U-shaped rotating rod rotatably disposed inside the concrete torpedo tank body, with a scraper at the top of the U-shaped rotating rod, the edge of the scraper closely abutting the inner wall of the concrete torpedo tank body. The beneficial effects of this invention are: simple structure and convenient use; it can transport concrete to a designated location and clean residual concrete from the inner wall of the torpedo tank body. However, the above structure can only perform simple scraping, but it cannot overcome the situation where concrete adheres to the scraper, or it cannot scrape off concrete that is firmly attached to the inner wall of the torpedo tank in time. At this time, the cleaning mechanism needs to be improved, for example, by making the cleaning mechanism have a vibration function to improve the scraping ability. For this reason, a torpedo tank concrete conveying control system with good scraping effect and precise adjustment is needed. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention provides a precisely adjustable torpedo-type concrete conveying control system with excellent scraping effect.

[0005] The objective of this invention can be achieved through the following technical solutions: A precisely adjustable torpedo-type concrete conveying control system includes a walking module and a torpedo can body mounted on the walking module. The torpedo can body is symmetrical about a reference line. Two parts of the torpedo can body that coincide with the reference line are provided with through holes. A rotating shaft is provided through the two through holes. A U-shaped plate is provided on the rotating shaft. The U-shaped plate is in contact with the inner wall of the torpedo can body. The torpedo canister body is provided with two hoop rings, each of which has a number of serrations inside. The two hoop rings are respectively fitted onto one end of the rotating shaft located outside the torpedo canister body. The rotating shaft is provided with a protrusion that abuts against the serrations. One end of the rotating shaft is connected to a motor, which drives the rotating shaft to rotate, thereby causing the protrusion on the rotating shaft to move relative to the serrations.

[0006] As a preferred embodiment of the present invention, the saw teeth inside the hoop are composed of several baffles, and any one of the baffles is hinged to the inner wall of the hoop and electrically connected to a control module. The control module is used to synchronously adjust the angle between the saw teeth and the inner wall of the hoop.

[0007] As a preferred technical solution of the present invention, it also includes a weight distribution sensor, which is used to detect the change in the distance between the center of gravity of the torpedo tank body and the standard position over time, calculate a comprehensive coefficient based on the distance and time, and increase the angle between the saw teeth and the inner wall of the hoop and reduce the speed of the motor when the comprehensive coefficient exceeds the threshold.

[0008] As a preferred embodiment of the present invention, the weight distribution sensor is used to detect the change of the distance L between the center of gravity of the torpedo canister and the standard position over time T, and to calculate the comprehensive coefficient X. When the control module determines that X exceeds X0, it adjusts the angle between the sawtooth and the inner wall of the hoop to α and adjusts the motor speed to Z; wherein, F(t) is a function of the centroid distance L as a function of time T, T0 is the pre-input acquisition time, α=X / X0×α0, Z=X0 / X×Z0, and α0, X0 and Z0 are pre-input constants.

[0009] As a preferred embodiment of the present invention, the control module is electrically connected to a humidity sensor. The humidity sensor is used to detect the humidity inside the torpedo canister and upload the data to the control module. The control module determines whether the humidity exceeds a threshold, and when the humidity exceeds the threshold, it corrects the angle between the sawtooth and the inner wall of the hoop upwards and corrects the motor speed downwards.

[0010] As a preferred technical solution of the present invention, the humidity sensor is used to detect the humidity S inside the torpedo canister and upload it to the control module. The control module corrects the angle between the upper correction sawtooth and the inner wall of the hoop ring upward by A1 times and corrects the speed of the correction motor downward by A2 times, where A1=S / S0×b, A2=S0 / S×c, and b and c are pre-corrected constants.

[0011] As a preferred embodiment of the present invention, a control panel is also included.

[0012] The beneficial effects of this invention are as follows: (1) By respectively fitting the hoop rings onto one end of the rotating shaft located outside the torpedo can body, and setting a protrusion that abuts against the saw teeth on the rotating shaft, the motor drives the rotating shaft to rotate, thereby causing the protrusion on the rotating shaft to move relative to the saw teeth. As the motor drives the U-shaped plate to rotate, the protrusion continuously hits the saw teeth, thus achieving vibration only when the U-shaped plate rotates, assisting the U-shaped plate to scrape off the cement from the inner wall of the torpedo can body. Compared with the scheme of setting an additional vibrator, the structure is simpler. At the same time, when the U-shaped plate is not rotating, the protrusion and the saw teeth play a locking role, preventing the U-shaped plate from shaking and affecting the cement transportation. (2) By setting up a weight distribution sensor, the distance between the center of gravity inside the torpedo tank and the standard position changes over time. The comprehensive coefficient is calculated based on the distance and time. When the comprehensive coefficient exceeds the threshold and there is a large amount of concrete accumulation, the angle between the saw teeth and the inner wall of the hoop is increased and the motor speed is reduced. This reduces the motor speed and increases the output torque when the center of gravity distribution deviates significantly over a long period of time, thereby increasing the vibration caused by the protrusion and improving the scraping effect on large amounts of concrete accumulation. In the absence of large amounts of concrete accumulation, the speed is increased to improve the scraping efficiency. (3) By comprehensively calculating the comprehensive coefficient, the influence of the fluctuation of the center of gravity under random factors on the adjustment is avoided by calculating the center of gravity distribution separately, thus improving the adjustment accuracy; (4) By setting a humidity sensor to test the humidity of the concrete, when the humidity is high and the scraping force is required to be large, the rotation speed is reduced and the output torque is increased, thereby increasing the scraping force.

[0013] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

Torpedo canister body; 11. Rotating shaft; 111. Protrusion; 12. Hoop; 121. Baffle; 2. U-shaped plate. Detailed Implementation

[0015] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0016] Please see Figure 1-3A precisely adjustable torpedo-type concrete conveying control system includes a walking module and a torpedo can body 1 mounted on the walking module. The torpedo can body 1 is symmetrical about a reference line. Two parts of the torpedo can body 1 that coincide with the reference line are provided with through holes. A rotating shaft 11 is provided through the two through holes. A U-shaped plate 2 is provided on the rotating shaft 11. The U-shaped plate 2 is attached to the inner wall of the torpedo can body. Two hoop rings 12 are provided on the outside of the torpedo can body 1. Each hoop ring 12 has several serrations inside. The two hoop rings 12 are respectively sleeved on one end of the rotating shaft 11 located outside the torpedo can body 1. The rotating shaft 11 is provided with a protrusion 111 that abuts against the serrations. One end of the rotating shaft 11 is connected to a motor. The motor drives the rotating shaft 11 to rotate, which in turn drives the protrusion 111 on the rotating shaft 11 to move relative to the serrations. During use, the torpedo canister body 1 is loaded with concrete. Before it is transported to the designated location, the start-up drive shaft 11 is activated to rotate the U-shaped plate 2. The U-shaped plate 2 moves close to the inner wall of the torpedo canister body 1 to scrape off the concrete. During this process, the protrusions continuously collide with several baffles 121. The vibration generated by the collision is transmitted to the U-shaped plate 2, which allows the U-shaped plate 2 to apply vibration to the concrete located on itself and the inner wall of the torpedo canister body 1, thereby improving the scraping effect.

[0017] By fitting the hoop 12 onto the end of the rotating shaft 11 located outside the torpedo can body 1, and providing a protrusion 111 on the rotating shaft 11 corresponding to the saw teeth to abut against the saw teeth, the motor drives the rotating shaft 11 to rotate, thereby causing the protrusion 111 on the rotating shaft 11 to move relative to the saw teeth. As the motor drives the U-shaped plate 2 to rotate, the protrusion 111 continuously impacts the saw teeth, achieving vibration only when the U-shaped plate 2 rotates, assisting the U-shaped plate 2 in scraping the cement off the inner wall of the torpedo can body 1. Compared with the solution of setting an additional vibrator, the structure is simpler. At the same time, when the U-shaped plate 2 is not rotating, the protrusion 111 and the saw teeth play a locking role, preventing the U-shaped plate 2 from shaking and affecting the cement transportation. The saw teeth inside the hoop 12 are composed of several baffles 121. Each baffle 121 is hinged to the inner wall of the hoop 12 and electrically connected to a control module. The control module is used to synchronously adjust the angle between the saw teeth and the inner wall of the hoop 12.

[0018] In actual use, during transportation, concrete will accumulate in a certain place inside the torpedo can body 1 due to inertia, forming a silt. At this time, it is necessary to increase the output torque and reduce the vibration caused by the protrusion 111. For this purpose, a weight distribution sensor is also included. The weight distribution sensor is used to detect the change of the distance between the center of gravity inside the torpedo can body 1 and the standard position over time. The comprehensive coefficient is calculated based on the distance and time. When it is determined that the comprehensive coefficient exceeds the threshold, the angle between the saw teeth and the inner wall of the hoop 12 is increased and the motor speed is reduced. By setting up a weight distribution sensor, the distance between the center of gravity inside the torpedo tank body 1 and the standard position changes over time. A comprehensive coefficient is calculated based on the distance and time. When the comprehensive coefficient exceeds the threshold and there is a large amount of concrete accumulation, the angle between the saw teeth and the inner wall of the hoop 12 is increased and the motor speed is reduced. This reduces the motor speed and increases the output torque when the center of gravity distribution deviates significantly over a long period of time, thereby reducing the vibration caused by the protrusion 111 and improving the scraping effect on large amounts of accumulated concrete. In scenarios without large amounts of accumulation, the speed is increased to improve the scraping efficiency. In the process of calculating the comprehensive coefficient, specifically, the weight distribution sensor is used to detect the change of the distance L between the center of gravity of the torpedo canister body 1 and the standard position over time T, and calculates the comprehensive coefficient X. When the control module determines that X exceeds X0, it adjusts the angle between the sawtooth and the inner wall of the hoop 12 to α and adjusts the motor speed to Z; wherein, F(t) is a function of the centroid distance L as a function of time T, T0 is the pre-input acquisition time, α=X / X0×α0, Z=X0 / X×Z0, and α0, X0 and Z0 are pre-input constants; By comprehensively calculating the comprehensive coefficient, the impact of short-term fluctuations in the center of gravity under random factors on the adjustment is avoided by calculating the center of gravity distribution separately, thus improving the adjustment accuracy. In some cases, the concrete has a high humidity level, which may lead to sedimentation. In such cases, it is necessary to increase the output torque and reduce the vibration caused by the protrusion 111. To this end, the control module is electrically connected to a humidity sensor. The humidity sensor is used to detect the humidity inside the torpedo canister body 1 and upload it to the control module. The control module determines whether the humidity exceeds the threshold and corrects the angle between the sawtooth and the inner wall of the hoop 12 upwards and the motor speed downwards when the humidity exceeds the threshold.

[0019] The humidity sensor is used to detect the humidity S inside the torpedo canister body 1 and upload it to the control module. The control module corrects the angle between the upper correction sawtooth and the inner wall of the hoop 12 upward by A1 times and corrects the speed of the correction motor downward by A2 times, where A1=S / S0×b, A2=S0 / S×c, and b and c are pre-corrected constants.

[0020] By setting a humidity sensor to test the humidity of the concrete, when the humidity is high and a greater scraping force is required, the rotation speed is reduced and the output torque is increased, thereby increasing the scraping force.

[0021] Working principle and usage process of this invention: During use, the torpedo canister body 1 is loaded with concrete. Before it is transported to the designated location, the start-up drive shaft 11 is activated to rotate the U-shaped plate 2. The U-shaped plate 2 moves close to the inner wall of the torpedo canister body 1 to scrape off the concrete. During this process, the protrusions continuously collide with several baffles 121. The vibration generated by the collision is transmitted to the U-shaped plate 2, which allows the U-shaped plate 2 to apply vibration to the concrete located on itself and the inner wall of the torpedo canister body 1, thereby improving the scraping effect.
