Description

Technical Field

[0001] This invention relates to the field of engineering transportation technology, specifically to a material conveying device for water conservancy projects that prevents deviation. Background Technology

[0002] Water conservancy projects are a general term for various engineering facilities built to control, regulate, and utilize water resources. They play an important role in flood control, irrigation, power generation, navigation, and water supply, and are essential infrastructure for national economic and social development.

[0003] Materials used in water conservancy projects mainly include concrete, earth and stone materials, metal materials, and organic materials. Due to the influence of terrain, material transportation relies heavily on small carts. The materials are generally large in weight and volume, and the transportation routes are often primarily muddy and have elevation differences, requiring the carts to make multiple round trips in batches.

[0004] When loading cargo onto a transport trolley, attention must be paid to the amount of material being loaded. Due to the diverse terrain of the transport route, bumps and jolting are more frequent during transport. Granular materials are prone to spillage and shifting, resulting in uneven distribution and a shift in the trolley's center of gravity, making subsequent transport more difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a material conveying device for hydraulic engineering that prevents deviation, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a material conveying device for water conservancy projects with anti-deviation capability, comprising a transport trolley and a control mechanism. The control mechanism includes a mounting plate, which is mounted on the frame of the transport trolley. A turntable is provided on the lower side of the mounting plate, and a set of pressure plates is provided on the turntable. A drive shaft is connected to the middle of the pressure plates. One end of the drive shaft extending out of the pressure plates is connected to a movable plate. The movable plate is provided with a slide rail, which is fixed on the turntable. The movable plate is provided with a connecting block one and a connecting block two. Several connecting rods are connected between the connecting block one and the connecting block two. The connecting block one is connected to the drive shaft, and the connecting block two is connected to a fixed shaft. A movable sleeve is fitted onto one end of the fixed shaft extending out of the connecting block two.

[0007] According to the above technical solution, the movable sleeve is located between the connecting block two and the pressure plate. The movable sleeve is rotatably connected to the fixed shaft. A push-pull rod is hinged on the movable sleeve, and a cylinder is hinged to the other end of the push-pull rod. The cylinder is fixed on the turntable.

[0008] According to the above technical solution, several cylinders are fixed on the mounting plate. The driving end of the cylinders passes through the mounting plate and is connected to a lifting plate. A rotary motor is installed on the lifting plate, and the driving end of the rotary motor is connected to the turntable.

[0009] According to the above technical solution, the pressure plate includes an upper pressure plate and a lower pressure plate. The lower pressure plate is connected and fixed to the drive shaft, and the upper pressure plate is rotatably engaged with the drive shaft. The upper pressure plate has several windows I on its upper circumference, and the lower pressure plate has windows II corresponding to the windows I. An adsorption layer is provided on the side of the upper pressure plate facing the lower pressure plate, and an electromagnetic layer is provided on the side of the lower pressure plate facing the upper pressure plate.

[0010] According to the above technical solution, the upper pressure plate is provided with a ring of edge teeth, and a movable toothed plate is provided on one side of the transport trolley frame. The movable toothed plate is fitted with a rail, and the movable toothed plate slides with the rail. A cylinder is fixed on one side of the rail, and the drive end of the cylinder is connected to the movable toothed plate. The movable toothed plate cooperates with the edge teeth.

[0011] According to the above technical solution, a set of scrapers is provided for each window 2 of the pressure plate. The scraper includes a drive plate and a deflection plate. The drive plate is hinged to both sides of the window 2. The deflection plate is connected to the drive plate and located on the lower side of the pressure plate. A torsion spring is provided at the connection between the drive plate and the window 2. The height of the drive plate is greater than the thickness of the pressure plate, and the width of the deflection plate is greater than the length of the boundary of the window 2.

[0012] According to the above technical solution, a visual monitoring module 1 is set on the lower side of the mounting plate to monitor the covering status of the materials inside the transport trolley during the transportation process, and a visual monitoring module 2 is set on the front of the transport trolley to monitor the road conditions during the transport trolley's travel.

[0013] According to the above technical solution, the mounting plate is set as a U-shaped structure, with rotating rods passing through both sides of the mounting plate. Twists are set at both ends of the rotating rods that extend out of the surface of the mounting plate. A long groove is opened on the side of the mounting plate facing the turntable. A clamping plate is connected to the part of the rotating rod located in the long groove. The distance from the axis of the rotating rod to its free end is greater than the depth of the long groove.

[0014] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, through the inclusion of a control mechanism, allows the pressure plate to control the height difference of the material surface inside the transport trolley via its telescopic and rotational movements. When the electromagnetic adsorption layer is energized, the upper and lower pressure plates close to form a rigid whole, flattening and compacting the material, reducing material loss due to splashing during transport. Furthermore, the inclusion of a second visual monitoring module allows for real-time scanning of road conditions, calculating the size, distribution density, and risk level of potholes. For low-risk potholes, the original route is maintained, avoiding unnecessary detours and significantly improving transport timeliness. For high-risk potholes, a balance is struck based on transport urgency: in high-urgency scenarios, the pressure plate is activated for reinforcement to ensure timely delivery of critical materials; in normal scenarios, risky paths are automatically avoided, achieving an optimal balance between safety and efficiency and reducing delays.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-9The present invention provides a technical solution: a material conveying device for water conservancy projects with anti-deviation capability, comprising a transport trolley 1 and a control mechanism. The control mechanism includes a mounting plate 2, which is mounted on the frame of the transport trolley 1. A turntable 3 is provided on the lower side of the mounting plate 2. A set of pressure plates 4 are provided on the turntable 3. A drive shaft 5 is connected to the middle of the pressure plates 4. A movable plate 51 is connected to one end of the drive shaft 5 extending out of the pressure plates 4. A slide rail 52 is provided on the movable plate 51 and fixed on the turntable 3. The movable plate 51 is provided with a first connecting block 511 and a second connecting block 512. A plurality of connecting rods 513 are connected between the first connecting block 511 and the second connecting block 512. The first connecting block 511 is connected to the drive shaft 5. A fixed shaft 514 is connected to the second connecting block 512. A movable sleeve 53 is sleeved on one end of the fixed shaft 514 extending out of the second connecting block 512.

[0019] The movable sleeve 53 is located between the connecting block 2 512 and the pressure plate 4. The movable sleeve 53 is rotatably engaged with the fixed shaft 514. A push-pull rod 54 is hinged on the movable sleeve 53. A cylinder 1 55 is hinged to the other end of the push-pull rod 54. The cylinder 1 55 is fixed on the turntable 3.

[0020] In actual operation, cylinder 55 is used to control the movement of the moving plate 51 on the slide rail 52. When the driving end of cylinder 55 extends, the push-pull rod 54 pushes the moving plate 51 through the movable sleeve 53 and the fixed shaft 514, moving it outward along the slide rail 52, so that the pressure plate 4 moves synchronously to the outer periphery of the turntable 3. When the driving end of cylinder 55 retracts, the push-pull rod 54 pulls the moving plate 51 inward along the slide rail 52, so that the pressure plate 4 moves synchronously to the inner periphery of the turntable 3.

[0021] In one embodiment, such as Figures 3-4 As shown, several cylinders 56 are fixed on the mounting plate 2. The driving end of the cylinders 56 passes through the mounting plate 2 and is connected to the lifting plate 57. A rotary motor 58 is installed on the lifting plate 57. The driving end of the rotary motor 58 is connected to the turntable 3.

[0022] In actual operation, the mounting plate 2 has reserved space for the rotary motor 58 to move. Cylinder 56 drives the lifting plate 57 to move up and down, so that the rotary motor 58 synchronously drives the turntable 3 to move up and down. The rotary motor 58 controls the turntable 3, thereby adjusting the direction of the pressure plate 4. Under normal conditions, the pressure plate 4 is horizontally positioned below the mounting plate 2 and within the inner circle of the turntable 3. When the rotary motor 58 drives the turntable 3 to rotate 90°, cylinder 55 can push the pressure plate 4 outward, so that the pressure plate 4 extends laterally beyond the coverage area of ​​the mounting plate 2.

[0023] like Figures 7-8As shown, the pressure plate 4 includes an upper pressure plate 41 and a lower pressure plate 42. The lower pressure plate 42 is connected and fixed to the drive shaft 5. The upper pressure plate 41 is rotatably engaged with the drive shaft 5. The upper pressure plate 41 has several windows 411 on its upper circumference. The lower pressure plate 42 has windows 421 corresponding to the windows 411. An adsorption layer 412 is provided on the side of the upper pressure plate 41 facing the lower pressure plate 42. An electromagnetic layer 422 is provided on the side of the lower pressure plate 42 facing the upper pressure plate 41.

[0024] The following is a supplementary explanation based on the above structure: In the initial state, window 1 411 and window 2 421 are staggered. When the electromagnetic layer 422 is energized, it generates a magnetic force to hold the adsorption layer 412, so that the upper pressure plate 41 and the lower pressure plate 42 are fixedly connected to each other and become a closed whole. At this time, the pressure plate 4 can be used to flatten and press the material. When the electromagnetic layer 422 is de-energized, the upper pressure plate 41 and the lower pressure plate 42 are separated from each other and become independent.

[0025] Furthermore, such as Figure 5 As shown, the upper pressure plate 41 is provided with a ring of edge teeth 413, and a movable toothed plate 61 is provided on one side of the frame of the transport trolley 1. The movable toothed plate 61 is fitted with a track 62, and the movable toothed plate 61 and the track 62 are slidably fitted. A cylinder 63 is fixed on one side of the track 62, and the driving end of the cylinder 63 is connected to the movable toothed plate 61. The movable toothed plate 61 and the edge teeth 413 are fitted together.

[0026] It should be further explained that the upper pressure plate 41 is controlled by cylinder 56 to adjust its height, thereby changing the connection state between the movable toothed plate 61 and the side tooth 413. When the movable toothed plate 61 and the side tooth 413 are misaligned, they are not connected. When the movable toothed plate 61 and the side tooth 413 are engaged, the upper pressure plate 41 and the lower pressure plate 42 are simultaneously separated. When cylinder 63 controls the movement of the movable toothed plate 61, the side tooth 413 drives the upper pressure plate 41 to rotate relative to the lower pressure plate 42. At this time, window 1 411 and window 2 421 can be switched to a one-to-one correspondence, and the upper pressure plate 41 and the lower pressure plate 42 are connected vertically.

[0027] Furthermore, such as Figure 8 As shown, a set of scrapers 43 is provided on the lower pressure plate 42 for each window 2 421. The scraper 43 includes a drive plate 431 and a deflection plate 432. The drive plate 431 is hinged to both sides of the window 2 421. The deflection plate 432 is connected to the drive plate 431 and is located on the lower side of the lower pressure plate 42. A torsion spring is provided at the connection between the drive plate 431 and the window 2 421. The height of the drive plate 431 is greater than the thickness of the lower pressure plate 42, and the width of the deflection plate 432 is greater than the length of the boundary of the window 2 421.

[0028] In actual operation, under the action of the torsion spring, and when window 1 411 and window 2 421 are connected, the scraper 43 is in a natural state without external interference. At this time, the drive plate 431 and the deflection plate 432 are perpendicular to the lower pressure plate 42. The upper surface of the drive plate 431 is higher than the upper surface of the lower pressure plate 42. The vertical scrapers 43 on both sides of window 2 421 can be used to frame the material under window 2 421. When the lower pressure plate 42 rotates, it will push the drive plate 431, causing the deflection plate 432 to be driven to rotate, thus releasing the vertical state. After window 1 411 and window 2 421 are completely misaligned, the upper end of the drive plate 431 abuts against the lower surface of the upper pressure plate 41, and the deflection plate 432 tilts towards the surface of the lower pressure plate 42.

[0029] A visual monitoring module 1 is installed on the lower side of the mounting plate 2 to monitor the covering status of the materials inside the transport trolley 1 during transportation. A visual monitoring module 2 is installed at the front of the transport trolley 1 to monitor the road conditions during the travel of the transport trolley 1.

[0030] Optional, such as Figure 9 As shown, the mounting plate 2 is configured with a U-shaped structure. Rotating rods 71 ​​are provided on both sides of the mounting plate 2. Twisting blocks 72 are provided at both ends of the rotating rods 71 ​​that extend out of the surface of the mounting plate 2. A long groove 21 is provided on the side of the mounting plate 2 facing the turntable 3. A clamping plate 73 is connected to the part of the rotating rod 71 located in the long groove 21. The distance from the axis of the clamping plate 73 to its free end is greater than the depth of the long groove 21.

[0031] In actual operation, the mounting plate 2 and the rotating rod 71 are threaded together. The rotating rod 71 is driven to rotate by the rotating torsion block 72, so that the clamping plate 73 can be clamped onto the surface of the transport trolley 1 frame, and the mounting plate 2 is locked to the transport trolley 1. When the clamping plate 73 is disengaged from the surface of the transport trolley 1 frame, the mounting plate 2 can slide freely on the transport trolley 1 frame.

[0032] Preferably, the transport vehicle 1 is equipped with a GPS positioning and automatic driving system.

[0033] The specific implementation method is as follows: In normal transportation, when materials need to be loaded, cylinder 2 56 controls turntable 3 to move upward. At this time, window 1 411 and window 2 421 are staggered and located within the inner circle of turntable 3. Materials are fed into the transport trolley 1 through both sides of mounting plate 2. Visual monitoring module 1 monitors the material feeding status to avoid excessive deviation between the height of the two sides and the center. Adjustments are made manually. After loading is completed, the transport trolley 1 enters the transport route, cylinder 2 56 controls the turntable 3 to be offset from the movable toothed plate 61, the turntable 3 adjusts the position of the pressure plate 4 so that the movable position of the pressure plate 4 is consistent with the direction of both sides of the mounting plate 2, cylinder 1 55 controls the pressure plate 4 to extend to both sides of the mounting plate 2, and cylinder 2 56 controls the turntable 3 to move down to the material surface. Transportation begins. The transport trolley 1 transports materials according to the pre-set route. During this time, the rotary motor 58 drives the turntable 3 to rotate back and forth periodically, so that the surface of the material is always within a certain height difference. At the same time, the turntable 3 can limit the material inside the transport trolley 1 from splashing out, avoiding the problem of material loss due to the bumpy transportation route. When the transport is completed, cylinder 55 controls the retraction of pressure plate 4, and movable tooth plate 61 controls window 411 to be offset from window 421, so that the material piled up on the upper pressure plate 41 falls into the transport trolley 1, and the staff transfers the material in the transport trolley 1.

[0034] Furthermore, in abnormal transportation situations, during transportation, the visual monitoring module two monitors road conditions in real time. If potholes are detected on the transportation route, it determines whether the transport vehicle 1 needs to be controlled to avoid them based on the size and number of potholes. A quantitative analysis of pothole characteristics is performed. First, based on the monitoring data from the visual monitoring module two (which can be combined with other sensors such as lidar or ultrasonic ranging), the dimensions (depth, width, and length) of the potholes are accurately measured. Simultaneously, the number of potholes and their distribution density (whether they are isolated single potholes, multiple consecutive potholes, or a dense group of potholes) are statistically analyzed. Based on a preset vehicle dynamics model and the current load status, the likelihood of the transport vehicle 1 safely and smoothly passing through the pothole area and the potential degree of bumpiness are assessed.

[0035] If the size and number of potholes are within the range that the transport vehicle 1's own shock absorption system and structural strength can effectively overcome, that is, if the predicted bump amplitude is lower than the preset safety threshold (for example, it will not cause material displacement, equipment damage, or affect driving stability), then it is determined that no avoidance is necessary. The transport vehicle 1 will continue to travel strictly according to the preset route to maximize transportation efficiency and save valuable transportation time.

[0036] When potholes and their quantity cause significant jolting on the transport trolley 1, the urgency of the transport determines whether evasive action is necessary. For example, if severe weather is imminent and could affect the quality of the transported materials, necessitating a transfer. If the jolting is frequent but not severe, the pre-set transport route can be strictly followed. Cylinder 2 56 raises the turntable 3, while the pressure plate 4 extends from both sides of the mounting plate 2. The pressure plate 4 and mounting plate 2 form a cap-like structure, minimizing material spillage. If the jolting is deemed too severe and would affect the safety of the transport trolley 1, evasive action is taken, and the pressure plate 4 is raised and extended to reduce the impact of severe weather on the materials.

[0037] Furthermore, if the visual monitoring module 2 detects a situation requiring climbing on the transport route, then control window 1 411 and window 2 421 overlap, the deflection plate 432 is lowered, the pressure plate 4 extends from both sides of the mounting plate 2, the turntable 3 is lowered, and after the deflection plate 432 penetrates into the material, the pressure plate 4 is retracted into the mounting plate 2, the turntable 3 is raised, and the above process is repeated, causing the material on both sides to shift towards the center, thereby adjusting the center of gravity of the transport trolley 1 and reducing the difficulty of climbing. Through multi-cycle progressive material migration, closed-loop control of the center of gravity position of the transport trolley 1 is achieved, overcoming the defect of traditional fixed and unadjustable counterweights. The forward shift of the center of gravity increases the load on the drive wheels, thereby improving climbing performance and reducing energy consumption compared to adding additional counterweights.
