Technical Field

[0001] The invention belongs to the technical field of emergency rescue equipment, and specifically relates to a multifunctional intelligent flood prevention and rescue vehicle. Background Art

[0002] As an important equipment for responding to flood disasters, flood control and rescue vehicles play a key role in flood control, disaster relief and emergency rescue. Their main functions include rapid drainage, transportation of rescue supplies, evacuation of trapped people and repair of damaged infrastructure. Flood control and rescue vehicles are highly maneuverable and multifunctional, and can operate efficiently in complex and harsh environments, significantly improving the response speed and operational efficiency of flood control and disaster relief.

[0003] When flood disasters occur, flood prevention and rescue vehicles can quickly reach the disaster area, use their powerful drainage and transportation capabilities to promptly remove accumulated water and reduce the threat of disasters to people's lives and property.

In addition, the introduction of intelligent control systems has improved the accuracy and safety of operations, ensuring that various rescue tasks can be completed stably and efficiently in emergency situations.

[0004] In the prior art, Chinese invention patent CN114537730B discloses a wingspan-type modular vehicle for filling and packing flood-control sandbags. The device includes a vehicle body, a carriage, a discharging assembly, a synchronous drive structure, a weighing assembly and a feeding assembly. The carriage is connected to the rear of the vehicle body and has a accommodating cavity. Both sides are provided with baffles connected to self-driving elements; the discharging assembly is rotatably arranged on the bottom surface of the accommodating cavity, and the discharging assembly has a packaging element; the synchronous drive structure connects the self-driving element and the discharging assembly; the weighing assembly is arranged in the accommodating cavity, above the discharging assembly; the feeding assembly is used to load into the accommodating cavity or be installed on the ground. When in use, the rescue personnel drive the vehicle body to the rescue position, then open the baffle and take out the feeding assembly, complete the connection and assembly of the device, and then carry out the sandbag filling and packing process.

[0008] The outer end of the bag pressing ring is fixedly connected with symmetrically arranged bag pressing rods, and the two bag pressing rods are symmetrically arranged along a plane parallel to the axis of the charging pipe and the center of the bag pressing ring.

[0009] The outer end of the loading tube is fixedly connected to the corresponding position of the bag pressing rod with a bag pressing cylinder corresponding to the bag pressing rod, the inner wall of the bag pressing cylinder is slidably connected to the outer end of the bag pressing rod, and the bottom end of the bag pressing cylinder close to one end of the discharge pipe is fixedly connected with a fixing ring, one end of the tying rope passes through the fixing ring and is fixedly connected to the bag pressing cylinder, and the other end is a self-tightening buckle.

[0010] The telescopic arm comprises an outer arm rotatably connected to the main arm, an inner arm of the outer arm is slidably connected to the middle arm, and an inner arm of the middle arm is slidably connected to the inner arm.

[0011] One end of the inner arm away from the outer arm is rotatably connected to the pitch adjustment shaft, the pitch adjustment shaft shaft passes through the inner arm, the outer end of the inner arm and the corresponding position of the pitch adjustment shaft shaft are fixedly connected to two pitch motors, and the pitch motor power shaft is fixedly connected to the pitch adjustment shaft shaft.

[0012] The loading motor, the slewing motor and the pitching motor are all hydraulic motors. A telescopic driving device is arranged in the telescopic arm, and a boom hydraulic cylinder is arranged between the boom and the telescopic arm.

[0015] The ends of the two shovel plates close to each other are arranged in contact with each other, and a rubber ring is fixedly connected to the bottom end of the discharge pipe.

[0016] In summary, this application has the following beneficial effects: 1. It is equipped with a fixed plate and a symmetrically arranged shovel plate. Through the coordinated action of the clamping hydraulic cylinder, it can quickly form a closed bucket structure and efficiently shovel mud, sand, pebbles and other materials. At the same time, the built-in screw and the loading motor work together to realize the spiral transmission of materials, ensuring that the materials can be stably and continuously transported to the discharge pipe and loaded into the bag, which greatly improves the loading efficiency and reduces the operation time. The tying rope can be used to tie the bag mouth during the falling process of the bag.

[0017] 2. The combined design of the bag pressing ring, the bag pressing rod and the bag pressing cylinder makes the bag fixing and releasing process simple and quick. Driven by the hydraulic system, the bag pressing ring can move up and down accurately to ensure that the bag is firmly fixed during the filling process to avoid material leakage or bag slippage.

[0019] 4. The combined design of the multi-section telescopic arm and the boom gives the flood control and rescue vehicle a wide operating range and height adjustment capability. The multi-section sliding connection structure inside the telescopic arm enables it to freely extend or retract according to operating requirements and adapt to operating environments of different distances and heights. The precise control of the pitch adjustment axis and the pitch motor further improves the adjustability of the operating angle, ensuring stable and efficient operation in complex terrain and narrow spaces.

[0020] 5. The loading motor, slewing motor and pitching motor are all hydraulically driven. Combined with the telescopic drive device and the boom hydraulic cylinder, an efficient and stable power transmission system is constructed. The centralized control and flow distribution of the hydraulic system ensure that each driving component can obtain sufficient power support under different operating conditions, thereby improving the stability and reliability of the overall operation. At the same time, the through-hole design of the loading pipe enables seamless connection between material transportation and the hydraulic drive system, which is not affected by the telescopic arm extension or boom pitch, thus ensuring a continuous and stable operation process.

[0021] 6. It integrates multiple functions such as shoveling, clamping, rapid bagging, dam slope clearing and telescopic shovel. It can adapt to various complex flood prevention and rescue scenes such as river banks, dams, potholes, etc. One device can complete multiple tasks, reducing equipment investment and site occupation, and improving the efficiency of emergency response. In addition, the intelligent control system makes the operation simple, improves the convenience of personnel operation and the safety of operation.

[0022] 7. The rubber ring at the bottom of the discharge pipe effectively prevents leakage or pocket falling during the filling process, improving the safety and reliability of the filling process. The application of rubber material not only extends the service life of the device, but also reduces the wear of the material on the equipment and reduces maintenance costs.

[0023] 8. Through the organic combination of the front-end shovel and the rear-end telescopic pitch system, a high degree of integration and collaborative work is achieved in the operation process.

[0026] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0027] Embodiment 1; like Figures 1 to 16 As shown, this embodiment mainly revolves around core components such as a fixed plate 1, a shovel plate 2, a clamping hydraulic cylinder 3, a loading pipe 4, a screw 5, a loading motor 6, a discharge pipe 10, a bag pressing ring 11, a bag 12, a bag pressing rod 13, and a bag pressing cylinder 14.

[0028] The fixing plate 1 serves as a base for the shoveling and clamping structure at the front end of the vehicle, and shoveling plates 2 are symmetrically arranged on both sides of the fixing plate 1 .

[0029] One end of the fixed plate 1 is fixedly connected with a loading pipe 4 for conveying the scooped materials to the discharge pipe 10 .

[0030] The shovel plate 2 and the fixed plate 1 are fixedly connected via two clamping hydraulic cylinders 3. When the clamping hydraulic cylinders 3 are contracted or extended, the shovel plates 2 can be driven to move closer to or farther from each other.

[0031] One end of the shovel plate 2 away from each other is fixedly connected with a baffle, and the end of the baffle away from the loading pipe 4 is provided with an arc-shaped notch, which can be used to clamp or position some objects that need to be grasped.

[0032] When shoveling or clamping is required, the shovel plates 2 can be brought closer to each other so that adjacent ends are in contact, forming a relatively sealed bucket space.

[0033] Two clamping hydraulic cylinders 3 are arranged between each shovel plate 2 and the fixed plate 1. The opening and closing angles of the shovel plates 2 can be flexibly adjusted by telescopic piston rods, so as to adapt to different angles, shapes and environments.

[0034] When shoveling materials, clamping objects or forming a bucket, the clamping hydraulic cylinder 3 can provide reliable force support and realize the function of clamping or shoveling objects.

[0035] The loading pipe 4 is fixed to one end of the fixing plate 1 and is used to transport the mud or pebbles in the bucket to the discharging pipe 10 .

[0036] A screw rod 5 is rotatably connected inside the charging tube 4 , and the screw rod 5 is fixedly connected to the power shaft of the charging motor 6 . When the charging motor 6 is working, it drives the screw rod 5 to rotate, thereby realizing the spiral transmission of the material.

[0037] The bottom end of the discharge pipe 10 is connected to the charging pipe 4 near the charging motor 6 for finally conveying the material to the bag 12 .

[0038] A bag pressing ring 11 is provided at the outer end of the discharge pipe 10 , and an interface bag 12 can be clamped between the discharge pipe 10 and the bag pressing ring 11 .

[0039] A groove is provided at the top of the bag pressing ring 11, and a tying rope 20 is provided in the groove. A fixing ring is fixedly connected to the bottom end of the bag pressing cylinder 14 near one end of the discharge pipe 10. One end of the tying rope 20 passes through the fixing ring and is fixedly connected to the bag pressing cylinder 14, and the other end is a self-tightening buckle.

[0040] A rubber ring is fixedly connected to the bottom end of the discharge pipe 10. The setting of the rubber ring can play a certain anti-slip and sealing role when filling the bag 12, and can also press the bag 12 and prevent the bag 12 from being crushed.

[0041] The outer end of the bag pressing ring 11 is fixedly connected with symmetrically arranged bag pressing rods 13 , and the two bag pressing rods 13 are symmetrically distributed along a plane parallel to the axis of the charging pipe 4 and the center of the bag pressing ring 11 .

[0042] A bag pressing cylinder 14 is fixedly connected to the outer end of the discharge pipe 10 at a position corresponding to the bag pressing rod 13 , and the inner wall of the bag pressing cylinder 14 is slidably connected to the outer end of the bag pressing rod 13 .

[0043] The bag pressing rod 13 can be driven to move up and down by the telescopic action of the bag pressing cylinder 14 , thereby driving the bag pressing ring 11 to move up and down, thereby achieving compression, fixation or loosening of the bag 12 .

[0044] Working process The vehicle is driven to a location where shoveling or clamping operations are required, and the vehicle body and the boom 9 (this embodiment is only used for simple reference, and a turntable is provided at the bottom of the boom 9 to connect with the vehicle body) are adjusted to appropriate positions.

[0045] First, the clamping hydraulic cylinder 3 is used to drive the shovel plate 2 to retract inward, so that the shovel plate 2 and the fixed plate 1 form a closed bucket structure on both sides.

[0046] Next, by driving or partially lifting the shovel board 2, the required materials (mud, pebbles, etc.) are shoveled into the bucket formed by the fixed plate 1 and the shovel board 2.

[0047] When the material in the bucket needs to be loaded into the bag 12, the bag 12 can be first clamped between the discharge pipe 10 and the bag pressing ring 11, and then the bag pressing cylinder 14 is started to drive the bag pressing rod 13 and the bag pressing ring 11 to move upward, and the bag 12 is pressed and fixed to the bottom end of the discharge pipe 10.

[0048] At this time, the loading motor 6 starts to work, driving the screw 5 to rotate, and the material in the bucket is transferred to the discharge pipe 10 through the loading pipe 4, and then enters the inside of the bag 12. After the bagging is completed, the bag 12 filled with materials is transported to the installation position, and then the bag pressing ring 11 is moved downward to the original position. The bag 12 is separated from the discharge pipe 10 and the bag pressing ring 11 under the action of gravity, and the filling is completed. When the bag 12 is full of materials, in the process of automatic falling, the bag 12 drives the tying rope 20 to move through friction. During the movement of the tying rope 20, the self-tightening buckle at one end is automatically pulled by the bag 12 and the fixing ring to automatically shrink and bind the top of the bag 12.

[0049] When it is necessary to use the arc-shaped notch of the baffle to grab a specific object, the clamping hydraulic cylinders 3 can be adjusted independently to allow the shovel plates 2 to move away from each other and rotate at a certain angle to form a structure similar to a clamp.

[0050] When the shovel plate 2 is brought close to the target object, the clamping hydraulic cylinder 3 is simultaneously pushed to contract or extend, so that the shovel plate 2 surrounds the target object and performs local positioning through the arc-shaped notch, thereby achieving the purpose of effective clamping.

[0051] Due to the position of the baffle and the design of the arc-shaped notch, the clamped items can maintain good stability and are not easy to slide or fall off.

[0052] During use, the rotary motor 7 can be used to drive the loading tube 4, the fixed plate 1 and the two shovel plates 2 to rotate as needed to achieve the rotary function; The fixed plate 1 and the shovel plate 2 form a bucket under the action of the clamping hydraulic cylinder 3, and the spiral conveying of the loading pipe 4, the screw 5 and the loading motor 6 can quickly transport materials such as mud, pebbles, etc. to the discharge pipe 10 and smoothly load them into the bag 12, thereby improving the bag filling efficiency.

[0053] The cooperation between the bag pressing ring 11, the bag pressing rod 13 and the bag pressing cylinder 14 enables the bag 12 to be easily pressed and fixed and dropped and released under the discharge pipe 10. The operator only needs to simply start the bag pressing cylinder 14 to complete the two processes of "fixing the bag opening" and "relaxing the bag opening" in a relatively short time.

[0054] The shovel plates 2 cooperate with the telescopic action of the clamping hydraulic cylinder 3 to freely adjust the angle between the shovel plates 2. When they are close together, they can form a tight bucket for filling materials. When they are unfolded, they can also use the arc-shaped notch on the baffle to clamp larger or specially shaped objects. It has a certain grasping adaptability.

[0055] A rubber ring is provided at the bottom end of the discharge pipe 10 , which can effectively prevent material leakage or pocket slippage during the process of filling the bag 12 . At the same time, the rubber material causes less wear on the bag 12 , thereby extending the service life of the bag 12 .

[0056] The multifunctional intelligent flood prevention and rescue vehicle has been specifically designed in the shoveling, clamping, filling and other links. The core structures such as the fixed plate 1, the shovel plate 2, the loading pipe 4, the bag pressing ring 11 and so on cooperate closely, making the device competent for a variety of complex flood prevention and rescue and emergency operation scenarios.

[0057] Through the combination of the above-mentioned structure and working process, Example 1 can take into account both the loading of large quantities of mud or gravel and the grabbing of individual materials or items of special shapes in actual use, helping rescue personnel to complete rescue tasks more efficiently and improving the comprehensive operating capabilities of the multifunctional intelligent flood prevention and rescue vehicle.

[0058] Example 2 like Figures 1 to 16 As shown, based on Example 1, the mechanical and hydraulic system parts related to the boom 9, telescopic arm and pitch adjustment are further improved.

[0059] The telescopic arm comprises an outer arm 15 rotatably connected to the main arm 9 , the inner part of the outer arm 15 is slidably connected to the middle arm 16 , and the inner part of the middle arm 16 is slidably connected to the inner arm 17 .

[0060] Through multi-stage coordination, the telescopic arm can be extended and retracted in stages to meet the working requirements at different distances or heights.

[0061] One end of the inner arm 17 away from the outer arm 15 is rotatably connected to the pitch adjustment shaft 8. The rotating shaft of the pitch adjustment shaft 8 passes through the inside of the inner arm 17, and two pitch motors 18 are fixedly connected to the outer end of the inner arm 17 at a position corresponding to the rotating shaft of the pitch adjustment shaft 8.

[0062] The power shafts of the two pitch motors 18 are fixedly connected to the rotating shaft of the pitch adjustment shaft 8 to achieve precise control of the up and down pitch angles of the telescopic arm.

[0063] The loading motor 6, the slewing motor 7 and the pitching motor 18 are all in the form of hydraulic motors. By connecting with the vehicle body hydraulic system, power output and flow distribution can be centralized to obtain a more stable and powerful driving capability.

[0064] The rotary motor 7 is mainly responsible for driving the rotation of the charging tube 4, thereby providing a rotary adjustment function for the bucket formed by the fixed plate 1 and the shovel plate 2; and the pitch motor 18 is specifically used to control the pitch angle of the telescopic arm.

[0065] A telescopic drive device is provided inside the telescopic arm, which usually adopts a mechanical structure such as a multi-stage hydraulic cylinder or a rack and pinion to realize the free extension or retraction of the multi-section arm.

[0066] A boom hydraulic cylinder 19 is arranged between the telescopic arm and the boom 9. The cylinder body of the boom hydraulic cylinder 19 is rotatably connected to the boom 9, and the piston rod is rotatably connected to the telescopic arm. By driving the boom hydraulic cylinder 19, the telescopic arm and the boom 9 can be pitched, folded or opened within a larger range.

[0067] The loading pipe 4 runs through the center of the boom 9 and the telescopic arm, so that when the mud, sand or gravel is pushed by the screw 5 in the bucket, it can be transported along the loading pipe 4 to the rear discharge pipe 10.

[0068] At the same time, the hydraulic pipe of the charging motor 6 also passes through the charging pipe 4, and the passing part is connected to the hydraulic system of the whole vehicle to ensure that the charging motor 6 can work normally under any extension, pitch or rotation conditions.

[0069] Working process When the vehicle travels to the area where operation is required, the operator can start the boom hydraulic cylinder 19 to allow the boom 9 and the telescopic arm to obtain a basic pitch angle in the vertical direction.

[0070] Through the telescopic drive device inside the telescopic arm, the outer arm 15, the middle arm 16 and the inner arm 17 can slide relative to each other and quickly extend to the desired length and height, providing a larger operating radius for the shovel board 2 or other front-end tools.

[0071] When the telescopic arm angle needs to be further adjusted, the pitch motor 18 drives the rotating shaft of the pitch adjustment shaft 8 to rotate after receiving the control command, so that the entire telescopic arm performs a slight pitch movement at the top of the boom 9.

[0072] If used in conjunction with the rotary motor 7, it can also drive the loading pipe 4 and the front end bucket to rotate within a certain range around the vertical axis of the vehicle body, forming a comprehensive adjustment with multiple degrees of freedom and achieving a more flexible working posture.

[0073] After the telescopic arm reaches the target position, the shovel plate 2 clamping or bucket shoveling function described in Example 1 can be called to shovel the material into the bucket formed by the fixed plate 1 and the shovel plate 2.

[0074] Then, the screw 5 is still driven by the loading motor 6 to transport the material to the discharge pipe 10, and the bag pressing ring 11, the bag pressing cylinder 14 and other structures are combined to achieve rapid bagging.

[0075] When the operating mode needs to be changed, the telescopic arm can also be extended and adjusted in pitch to adapt to different task scenarios such as grabbing, loading or excavating.

[0076] During the entire working process, whether it is the charging motor 6, the rotary motor 7 or the pitch motor 18, they can obtain stable power through the vehicle body hydraulic system.

[0077] When in use, the vehicle body is driven to the desired position; When the bag 12 needs to be filled with sand or pebbles, the bag 12 to be filled is placed between the discharge pipe 10 and the bag pressing ring 11, and then the two bag pressing rods 13 are moved upward by the two bag pressing cylinders 14, and the bag pressing rods 13 then drive the bag pressing ring 11 to move upward, and the bag pressing ring 11 squeezes the bag 12 to the bottom end of the discharge pipe 10, thereby fixing the bag 12; The two shovel plates 2 are brought close to each other and pressed against the two ends of the fixed plate 1 by the clamping hydraulic cylinder 3 to form a complete bucket. The required materials are then scooped up by the bucket. The bucket composed of the fixed plate 1 and the shovel plate 2 is then lifted upward by the pitch motor 18. The screw 5 is then driven to rotate by the loading motor 6. During the rotation of the screw 5, the materials in the bucket composed of the fixed plate 1 and the shovel plate 2 are transported to the bag 12 through the loading pipe 4 and the discharge pipe 10 until the bag 12 is filled. After the filling is completed, the bag pressing ring 11 is moved downward. At this time, the bag 12 is separated from the discharge pipe 10 and the bag pressing ring 11 under the action of gravity, and the filling is completed. When it is necessary to grab an object, the two shovel plates 2 are expanded and rotated outward by independently adjusting the movement of the piston rod on each clamping hydraulic cylinder 3, so that the two shovel plates 2 form a clamping claw, and then the two shovel plates 2 are driven to move by synchronously driving multiple clamping hydraulic cylinders 3 to clamp the object; In addition to the loading and clamping functions, the two shovel plates 2 and the fixed plate 1 can also be used to form a bucket, which can be used as a conventional shovel truck or excavator to achieve the quick loading function, gripping function, dam slope clearing function, telescopic shovel insertion function, etc. with automatic uncoupling with telescopic rotation function.

[0078] Since the hydraulic pipe of the charging motor 6 passes through the charging pipe 4 and is connected to the hydraulic system, even if the length of the telescopic arm changes, it will not affect the continuous operation of the screw 5, thereby achieving continuous and stable material transportation.

[0079] Through the sliding combination of the outer arm 15, the middle arm 16 and the inner arm 17, the telescopic arm can be adjusted in length over a large range. The cooperation with the boom hydraulic cylinder 19 gives the device a three-dimensional operating radius, which significantly improves the practicability of crossing obstacles, crossing rivers and crossing embankments in emergency environments.

[0080] The establishment of the pitch motor 18 enables the pitch adjustment axis 8 to perform more precise angle adjustment to meet the requirements of loading and clamping at different heights or angles, especially when operating in areas with rugged terrain or narrow space, its operational flexibility is more prominent.

[0081] The through-hole design of the loading pipe 4 and the reasonable layout of the hydraulic pipeline ensure that the feeding function of the front shovel plate 2, the fixed plate 1 and the screw 5 will not be restricted by the extension and retraction of the telescopic arm or the pitching of the boom 9.

[0082] Regardless of the length or inclination of the telescopic arm, the loading motor 6 can still run at high speed, and the materials can be transported to the discharge pipe 10 for bagging or throwing in time, which significantly improves the efficiency of the rescue work.

[0083] The loading motor 6 , the slewing motor 7 and the pitching motor 18 are all in the form of hydraulic motors, and can form a complete hydraulic drive system with the boom hydraulic cylinder 19 and the clamping hydraulic cylinder 3 .

[0084] Through unified hydraulic control and flow distribution, it can not only ensure that each motor has sufficient power supply during operation, but also effectively avoid mutual interference between different actions, making the overall operation more stable and reliable.

[0085] The telescopic arm's free extension capability and pitch adjustment can adapt to a variety of complex environments such as river banks, dams, potholes, etc., and realize multiple functions such as shoveling, clamping, rapid bagging, dam slope clearing, and telescopic shovel insertion.

[0086] When combined with the front-end structure described in Example 1, one device can complete most flood prevention and rescue tasks, reduce equipment investment and site occupation, and improve emergency efficiency.

[0087] Through the coordination of the above structures and working processes, Example 2 further enhances the operating range, operational flexibility and overall linkage of the multifunctional intelligent flood prevention and rescue vehicle, and is closely combined with the front-end clamping and loading structure of Example 1 to form an integrated flood prevention and rescue system with complete functions, diverse actions and easy operation.

[0088] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
