Description
Technical Field
[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a mini fire truck for hose collection and laying. Background Technology
[0002] Mini fire trucks, with their compact size, high mobility, and suitability for navigating complex environments such as community roads, narrow streets, factory access roads, and mountainous forest areas, have been increasingly used in initial fire suppression, long-distance water supply assistance, and emergency rescue. In practical use, in addition to transporting conventional firefighting equipment, mini fire trucks also need to efficiently store, transfer, and re-lay fire hoses within their limited onboard space to improve water supply efficiency at the fire scene and reduce the workload of firefighters.
[0003] In existing technologies, the on-board retrieval and storage of fire hoses typically employs manual sorting combined with truck compartment storage, or automated retrieval, guided conveying, and compartmentalized stacking methods to place the retrieved fire hoses inside the truck compartment for subsequent release. These methods improve hose retrieval efficiency to some extent and reduce the burden of manual handling and sorting. However, fire hoses are flexible, strip-shaped components, and their layer morphology is easily affected by factors such as space dimensions, stacking height, stress state, and local structural differences during retrieval and continuous stacking. Especially in the case of limited space in mini fire truck compartments and restricted storage areas, maintaining high storage density, good layer stability, and smooth subsequent release performance within a limited space remains a key technical challenge for this type of equipment.
[0004] Furthermore, fire hoses in actual use are usually not completely uniform flexible materials; they may have relatively thick and rigid structural parts such as joints and connectors in certain areas. These local structures, once in the vehicle-mounted storage area, can easily interfere with the overall stacking arrangement, causing localized bulges between hose layers, uneven stress, or disordered arrangement. This further affects the continued storage effectiveness of subsequent hoses and the smoothness of release during re-laying. Especially under conditions of multi-layer continuous stacking, repeated transport, and vehicle vibration, existing technologies often struggle to simultaneously ensure orderly hose storage, inter-layer stability, and control over the impact of connections on the overall stacking arrangement, leading to uneven localized stacking of hoses during storage.
[0005] Therefore, we propose a mini fire truck for hose collection and laying. Summary of the Invention
[0006] The purpose of this invention is to provide a mini fire truck for hose collection and laying, to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a mini fire truck for hose collection and laying, comprising: car; A laying device is installed on the upper side of the carriage. The laying device is used to clamp and transport the water hose and to avoid encountering water hose joints. A three-axis drive unit is installed on the carriage and is used to drive the laying device to move within the carriage space. A storage mechanism is provided inside the carriage for storing hose connectors; The partition has several partitions that divide the carriage into several storage compartments. Each storage compartment contains a water hose plate, and the carriage is equipped with a drive device that moves the water hose plate up and down.
[0007] Preferably, the laying device includes: A connecting plate, the top of which is used for connection to a three-axis drive device; The rotating plate has two sets of rotating plates symmetrically arranged about the vertical center plane of the connecting plate. Each end of the rotating plate is rotatably connected to a clamping roller, and each end of the clamping roller is fixedly connected to a chain tooth. The chain teeth are connected to each other by a chain. One end of the rotating plate is provided with a driving mechanism to drive the chain teeth to rotate. The rotating plate is rotatably connected to the connecting plate. The connecting plate is provided with a pushing mechanism, which is used to drive the rotating plate to rotate and avoid the hose connector.
[0008] Preferably, the drive mechanism includes: Servo motor one, the outer shell of servo motor one is fixedly connected to the rotating plate, the output shaft end of servo motor one is fixedly connected to roller one, and roller two is fixedly connected to the chain tooth one near the end of servo motor one. Roller one and roller two are driven by a drive belt.
[0009] Preferably, the actuating mechanism includes: An electric cylinder, wherein the outer shell of the electric cylinder is fixedly connected to a connecting plate, a guide rail plate is fixedly connected to the end of the output shaft inside the electric cylinder, a horizontal plate is fixedly connected to the middle of the rotating plate, and a slider is fixedly connected to one end of the horizontal plate near the guide rail plate, the slider being slidably connected inside the guide rail plate.
[0010] Preferably, the storage mechanism includes: The connecting rod consists of two rods, which are located inside the storage cavity. Both ends of the connecting rod are rotatably connected to the partition, and a chain tooth is fixedly connected to the middle of the connecting rod. The chain teeth are connected to each other via a chain. The storage belt is U-shaped and has a connecting ear between it and the second chain. One end of the connecting ear is fixedly connected to the storage belt and the other end is fixedly connected to the second chain. The storage belt is made of flexible material. A round rod is provided between the second chain and the water hose plate. One end of the round rod is fixedly connected to the second chain and the other end is fixedly connected to the water hose plate.
[0011] Preferably, the storage cavity is provided with a plurality of abutment rods, which are located on both sides of the storage belt and arranged symmetrically in pairs. The ends of the abutment rods are rotatably connected to abutment wheels, which abut against the storage belt.
[0012] Preferably, the driving device includes: The guide rail is fixedly connected to the carriage, the water hose plate is slidably connected to the guide rail, and a second servo motor is provided on the partition plate. The end of the internal output shaft of the second servo motor is fixedly connected to the connecting rod.
[0013] The present invention has at least the following beneficial effects: By incorporating several storage compartments separated by partitions within the vehicle, fire hoses can be stored in designated areas after retrieval, preventing large quantities of hoses from piling up in a single area. This improves the utilization of interior space and reduces the likelihood of hoses becoming tangled and disorganized. The vertically movable hose support plate and drive mechanism dynamically adjust the support position as hoses continuously enter the storage compartments, maintaining a relatively stable stack during layer-by-layer installation. This reduces excessive free fall caused by changes in stacking height, thus improving the neatness and stability of hose storage. A three-axis drive mechanism above the vehicle allows the laying device to move flexibly above multiple storage compartments, enabling a single laying device to fit multiple compartments and minimizing the space occupied by repetitive overall structural designs. Meanwhile, the laying device can avoid the hose connectors during transportation, and the storage mechanism can store the hose connectors separately. This effectively reduces the local protrusions formed when hose connectors are directly stacked in the middle of ordinary hose layers, avoiding interference with the continued laying of subsequent hose layers and reducing the possibility of the hoses being stuck, pressed, or pulled during re-laying, which could affect the smooth release of the hoses. Therefore, this embodiment can balance hose collection, zoned stacking, orderly placement of connectors, and smooth subsequent laying within the limited space of a mini fire truck. By installing two sets of relatively rotatable rotating plates on the connecting plate, and clamping rollers on these rotating plates, the laying device structurally possesses both stable clamping and active obstacle avoidance functions. During ordinary hose conveying, the clamping rollers provide a relatively continuous and stable traction force on the hose, improving the stability of the conveying process and reducing slippage, deviation, and discontinuity. When the hose connector passes through, the pushing mechanism drives the rotating plates to rotate, creating a larger clearance between the clamping rollers. This prevents hard pressure or jamming between the hose connector and the clamping rollers, ensuring the connector passes smoothly through the laying device. Furthermore, the two sets of rotating plates are symmetrically arranged about the vertical center plane of the connecting plate, ensuring relatively balanced force during clamping and conveying. This helps reduce hose skewing during conveying and improves the overall smoothness of the conveying operation. By configuring the coordination between the electric cylinder, guide plate, cross plate, and slider, the pushing mechanism can achieve stable driving of the rotating plate with a relatively simple structure. Compared to simply using a push-type structure to directly act on the rotating plate, this embodiment uses the guide plate to slide and guide the slider. This not only improves the smoothness of the rotating plate's movement during rotation but also reduces jamming or uneven force caused by deviation in the direction of the pushing force, thereby improving the reliability of the pushing mechanism. Meanwhile, the electric cylinder itself has the characteristics of controllable stroke and fast response, so the distance between the two sets of clamping rollers can be adjusted in time according to the timing of the hose connector's passage, allowing for a smoother switching between ordinary hose conveying and hose connector avoidance. Through the above configuration, a relatively stable clamping force can be ensured for the ordinary hose body during conveying, and local space can be quickly released when the hose connector arrives, thereby reducing the possibility of top pressure, jamming, or transmission interruption when the connector passes.

[0016] 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.
[0017] Please see Figure 1-7 This invention provides a technical solution: a mini fire truck for hose collection and laying, comprising: Carriage 10; A laying device 20 is disposed on the upper side of the carriage 10. The laying device 20 is used to clamp and transport the water hose and to avoid encountering the water hose connector. A three-axis drive device 30 is mounted on the carriage 10 and is used to drive the laying device 20 to move within the space of the carriage 10. Storage mechanism 40, which is disposed inside the carriage 10, is used to store water hose connectors; A partition 51 is provided, and a plurality of partitions 51 are provided to divide the carriage 10 into a plurality of storage compartments. A water hose plate 52 is provided in each storage compartment, and a drive device 53 is provided in the carriage 10 to drive the water hose plate 52 to move up and down. It should be noted that when fire hoses need to be retrieved and stored, the operator first controls the three-axis drive device 30 to move the laying device 20 to the position above the corresponding storage chamber. Then, the laying device 20 clamps the retrieved fire hose and continuously conveys it along a preset direction, allowing the hose to gradually enter the corresponding storage chamber. Since the carriage 10 is divided into multiple independent storage chambers by several partitions 51, the hoses can be conveyed to different storage chambers for zoned storage according to the hose length, retrieval sequence, or different task requirements, thereby avoiding local disorder caused by all hoses being piled up in the same area. As the hoses continuously enter the corresponding storage chambers, they are laid layer by layer on the hose plate 52. In order to reserve sufficient stacking space for the hoses that enter later, the drive device 53 drives the hose plate 52 to move downwards step by step, so that the stacking height of the hoses in the current storage chamber is always kept within a relatively suitable range, thereby reducing the situation of overturning, overlapping, and uneven stacking caused by the hoses falling too far. Furthermore, during the hose conveying process, when the laying device 20 detects the hose connector approaching its location, the laying device 20 temporarily changes its clamping state at the hose connector and avoids it, allowing the hose connector to pass smoothly through the laying device 20 and preventing it from getting stuck due to its large size or thicker areas. After the hose connector passes through the laying device 20, the three-axis drive device 30 can continue to move the laying device 20, bringing the hose connector closer to the storage mechanism 40, where the storage mechanism 40 stores the hose connector separately. Because the storage mechanism 40 is used to independently receive the hose connector, the hose connector will not fall directly onto the middle area of the ordinary hose layer, thus reducing the local bulges formed by directly stacking hose connectors. Meanwhile, as the water hoses continue to stack in the corresponding storage chamber, the drive device 53 continues to drive the water hose plate 52 to move downward, causing the laid water hose layer to move downward as a whole. The water hose connectors received by the storage mechanism 40 can also maintain a positional relationship adapted to the current water hose layer as the corresponding layer changes, so as to avoid the water hose connectors being fixed at a certain absolute height position and causing traction on the adjacent water hose layers.
[0018] It is worth noting that this embodiment, by setting several storage cavities separated by partitions 51 within the carriage 10, allows for the partitioned storage of fire hoses after retrieval, preventing a large number of hoses from piling up in a single area. This helps improve the utilization rate of the carriage's internal space and reduces the probability of hoses becoming tangled and disorderly stacked. By setting up a vertically movable hose plate 52 and a drive device 53, the support position can be dynamically adjusted as the hoses continuously enter the storage cavities, maintaining a relatively stable stacking state during the layer-by-layer laying process. This reduces the problem of excessive free fall caused by constantly changing stacking height, thereby improving the neatness and stability of hose storage. By setting a three-axis drive device 30 above the carriage 10, the laying device 20 can be flexibly moved above multiple storage cavities, allowing the same laying device 20 to fit multiple storage cavities, reducing the space occupation problem caused by repetitive overall structural setups. Meanwhile, the laying device 20 can avoid the hose connectors during transportation, and the storage mechanism 40 can store the hose connectors separately. This effectively reduces the local protrusions formed when the hose connectors are directly stacked in the middle of the ordinary hose layer, avoiding interference from local protrusions on the continued laying of subsequent hose layers, and reducing the possibility of the hoses being stuck, pressed, or pulled during re-laying, which could affect the smooth release of the hoses. Therefore, this embodiment can take into account hose collection, zoned stacking, orderly placement of connectors, and smooth subsequent laying within the limited space of the mini fire truck.
[0019] Further as Figure 3 As shown, it is worth noting that the laying device 20 includes: Connecting plate 21, the top of which is used to connect to the three-axis drive device 30; The rotating plate 22 has two sets of rotating plates symmetrically arranged about the vertical center of the connecting plate 21. Both ends of the rotating plate 22 are rotatably connected to clamping rollers 23. The ends of the clamping rollers 23 are fixedly connected to chain teeth 24. The chain teeth 24 are connected to each other by a chain 27. One end of the rotating plate 22 is provided with a driving mechanism 25 to drive the chain teeth 24 to rotate. The rotating plate 22 is rotatably connected to the connecting plate 21. The connecting plate 21 is provided with a pushing mechanism 26, which is used to drive the rotating plate 22 to rotate and avoid the hose connector. It should be noted that when collecting or laying fire hoses, the three-axis drive device 30 first moves the connecting plate 21 to a predetermined position, aligning the laying device 20 with the location of the hose to be transported or above the corresponding storage chamber. Subsequently, the drive mechanism 25 operates, driving one set of chain teeth 24 to rotate. Under the transmission of the chain 27, the other set of chain teeth 24 rotates synchronously, causing the clamping rollers 23 mounted on the two sets of rotating plates 22 to rotate synchronously. Since the two sets of rotating plates 22 are symmetrically arranged about the vertical center of the connecting plate 21, and the clamping rollers 23 are distributed at both ends of the rotating plates 22, the two sets of clamping rollers 23 can clamp the hose and drive it to move stably in a predetermined direction during rotation, thus achieving continuous hose transport. Under normal transport conditions, the two sets of rotating plates 22 remain relatively close to ensure that the clamping rollers 23 form a relatively stable clamping force on the hose body, allowing the hose to be continuously pulled forward. When the hose connector reaches the laying device 20, because the hose connector has a greater thickness and higher local rigidity than the ordinary hose body, the pushing mechanism 26 is activated, causing the corresponding rotating plate 22 to rotate around its connection position with the connecting plate 21. This increases the distance between the two sets of clamping rollers 23, creating a clearance space inside the laying device 20 for the hose connector to pass through, allowing it to pass smoothly without easily getting stuck between the clamping rollers 23. After the hose connector passes, the pushing mechanism 26 drives the rotating plate 22 back to its initial position, causing the clamping rollers 23 to clamp the subsequent hose body again, continuing the subsequent conveying process. In this way, the laying device 20 can continuously clamp and convey the ordinary hose body while actively avoiding the approach of the hose connector, thus balancing the continuity of conveying and the smooth passage of the connector. It is worth noting that by setting two sets of relatively rotatable rotating plates 22 on the connecting plate 21, and setting clamping rollers 23 on the rotating plates 22, the laying device 20 structurally possesses both stable clamping and active avoidance functions. Specifically, during ordinary hose conveying, the clamping rollers 23 can provide a relatively continuous and stable traction force on the hose, which helps improve the stability of the hose conveying process and reduces slippage, deviation, and discontinuous conveying. When the hose connector passes through, the pushing mechanism 26 can drive the rotating plates 22 to rotate, creating a larger passage gap between the clamping rollers 23, thereby preventing hard pressure or jamming between the hose connector and the clamping rollers 23, ensuring the connector passes smoothly through the laying device 20. Furthermore, the two sets of rotating plates 22 are symmetrically arranged about the vertical center plane of the connecting plate 21, ensuring relatively balanced force on the laying device 20 during clamping and conveying, thus reducing hose skewing during conveying and improving the overall smoothness of the conveying action.
[0020] Further as Figure 2As shown, it is worth noting that the drive mechanism 25 includes: Servo motor 251, the outer shell of servo motor 251 is fixedly connected to rotating plate 22, and roller 252 is fixedly connected to the end of the output shaft inside servo motor 251. Roller 253 is fixedly connected to the chain tooth 24 near one end of servo motor 251. Roller 252 and roller 253 are driven by drive belt 254. It should be noted that the servo motor 251 is mounted on the rotating plate 22, so it can rotate synchronously with the plate 22. This ensures that when the pushing mechanism 26 drives the rotating plate 22 to avoid the hose connector, the drive mechanism 25 as a whole can maintain a relatively stable assembly relationship with the corresponding clamping roller 23, preventing the drive transmission from being affected by changes in the position of the rotating plate 22. In actual operation, after the servo motor 251 starts, its output shaft drives the idler roller 252 to rotate. The idler roller 252 then drives the second idler roller 253 to rotate synchronously via the drive belt 254. Since the second idler roller 253 is fixedly connected to the chain tooth 24 near the end of the servo motor 251, the chain tooth 24 can rotate synchronously with the second idler roller 253. Furthermore, the chain teeth 24 are connected by a chain 27, causing the chain teeth 24 at the other end to rotate synchronously as well, ultimately driving the clamping rollers 23 at both ends to rotate together, thus achieving the clamping and conveying of the hose. Through the aforementioned transmission path, the power of the servo motor 251 can be transmitted relatively stably to the clamping rollers 23 at both ends, enabling the clamping rollers 23 to form a continuous traction effect when conveying the water belt. Simultaneously, because the servo motor 251 itself has good start-stop control and speed adjustment capabilities, the rotation speed of the clamping rollers 23 can be adjusted according to the actual needs during the water belt recovery or laying process to adapt to the working requirements under different conveying rhythms. Further as Figure 4 As shown, it is worth noting that the actuating mechanism 26 includes: Electric cylinder 261, the outer shell of electric cylinder 261 is fixedly connected to connecting plate 21, the output shaft end of electric cylinder 261 is fixedly connected to guide rail plate 262, the middle part of rotating plate 22 is fixedly connected to horizontal plate 263, and the end of horizontal plate 263 near guide rail plate 262 is fixedly connected to slider 264, which is slidably connected inside guide rail plate 262; It should be noted that the electric cylinder 261 is fixedly mounted on the connecting plate 21, so the electric cylinder 261 can provide a stable linear pushing force relative to the connecting plate 21 when it is working. After the electric cylinder 261 is started, its output shaft extends or retracts in a predetermined direction, thereby driving the guide plate 262 to move synchronously. Since the horizontal plate 263 is fixedly connected to the middle of the rotating plate 22, and the slider 264 on the horizontal plate 263 is slidably connected to the guide plate 262, the guide plate 262 can apply a guiding and pushing effect to the horizontal plate 263 through the slider 264 during the movement, thereby driving the rotating plate 22 to rotate around its rotational connection with the connecting plate 21. When the ordinary water hose passes through the laying device 20, the electric cylinder 261 remains in its initial state, keeping the two sets of rotating plates 22 in a relatively close position, thus ensuring that the clamping rollers 23 maintain normal clamping of the water hose. When the water hose connector moves between the clamping rollers 23, the electric cylinder 261 actuates, pushing the guide rail plate 262 to move. This causes the horizontal plate 263 to deflect via the slider 264, causing the rotating plate 22 to rotate outward around the rotating connection point, increasing the distance between the clamping rollers 23 to create clearance space for the water hose connector to pass through. After the water hose connector passes, the electric cylinder 261 reverses its action, the guide rail plate 262 returns to its original position, and the horizontal plate 263 is reset via the slider 264, causing the rotating plate 22 to rotate back to its original clamping position, thereby resuming the clamping and conveying of subsequent water hose bodies. Through the above method, the pushing mechanism 26 can quickly drive the rotating plate 22 to rotate when the water hose connector arrives and reset in time after the connector passes, thus ensuring that the laying device 20 has good adaptability under different conveying conditions. It is worth noting that by setting the cooperative relationship between the electric cylinder 261, guide rail plate 262, cross plate 263, and slider 264, the pushing mechanism 26 can achieve stable driving of the rotating plate 22 with a relatively simple structure. Compared with the method of directly acting on the rotating plate 22 using a push-type structure, this embodiment uses the guide rail plate 262 to slide and guide the slider 264, which not only helps to improve the smoothness of the rotating plate 22 during rotation, but also reduces the jamming or uneven force caused by the deviation of the pushing force direction, thereby improving the reliability of the pushing mechanism 26. At the same time, the electric cylinder 261 itself has the characteristics of controllable stroke and fast response, so the distance between the two sets of clamping rollers 23 can be adjusted in time according to the passing time of the hose connector, so that the laying device 20 can achieve a smoother switching between ordinary hose body conveying and hose connector avoidance. The above settings ensure that the ordinary water hose body obtains a relatively stable clamping force during the conveying process, and can quickly release local space when the water hose connector arrives, thereby reducing the possibility of pressure, jamming or transmission interruption when the connector passes through.
[0021] Further as Figure 5 As shown, it is worth noting that the storage mechanism 40 includes: Connecting rod 41, there are two connecting rods 41, the connecting rod 41 is set in the storage cavity, the two ends of the connecting rod 41 are rotatably connected to the partition 51, and the middle part of the connecting rod 41 is fixedly connected to the chain teeth 42, and the chain teeth 42 are connected to each other by a chain 43. The storage belt 44 is U-shaped. A connecting ear 45 is provided between the storage belt 44 and the second chain 43. One end of the connecting ear 45 is fixedly connected to the storage belt 44, and the other end is fixedly connected to the second chain 43. The storage belt 44 is made of flexible material. A round rod 46 is provided between the second chain 43 and the water hose plate 52. One end of the round rod 46 is fixedly connected to the second chain 43, and the other end is fixedly connected to the water hose plate 52. It should be noted that the two connecting rods 41 are respectively positioned at opposite locations within the storage cavity, and form a transmission relationship through the second chain tooth 42 and the second chain 43, thereby enabling the second chain 43 to form a circulating transmission structure within the storage cavity. The storage belt 44 is fixed to the second chain 43 via the connecting ear 45, so the storage belt 44 can move synchronously with the second chain 43 during operation. Since the storage belt 44 is U-shaped and made of flexible material, when the hose connector moves to the corresponding position of the storage mechanism 40 after being bypassed by the laying device 20, it can be pressed into the storage belt 44 by external force. The storage belt 44 can undergo elastic deformation under pressure to accommodate the hose connector; after the hose connector enters, the storage belt 44 can wrap and limit the hose connector by its own flexible rebound, thereby keeping the hose connector in a predetermined area on the side of the storage cavity, rather than being directly stacked in the middle of the ordinary hose layer; A round rod 46 is provided between chain 2 43 and hose plate 52. Therefore, when hose plate 52 moves downward under the action of drive device 53, round rod 46 can drive the corresponding part of chain 2 43 to move synchronously, so that the storage belt 44 installed on chain 2 43 moves downward accordingly. As a result, the hose connector located in storage belt 44 can maintain a positional relationship adapted to the current stacking layer as the corresponding hose layer descends as a whole. In this way, when subsequent hoses continue to enter the storage cavity and are stacked layer by layer, the hose connector will not continuously pull on the hoses below or to the side due to being fixed at a certain absolute height position. At the same time, it can also avoid the hose connector directly pressing between ordinary hose layers and forming obvious bulges. In the above way, storage mechanism 40 can individually receive, limit, and move the hose connector synchronously with the layer during the continuous storage of hoses, so that the ordinary hose body and the hose connector are distinguished in terms of storage path and stress state, improving the orderliness of the overall storage state. It is worth noting that by setting up a transmission structure consisting of connecting rod 41, chain teeth 42, and chain 43, the storage belt 44 can not only be set on the side of the storage cavity, but also adjust its position when the position of the hose plate 52 changes, so that the storage position of the hose connector is no longer fixed. The advantages of this setting are twofold: firstly, it allows the hose connector to be separated from the main stacking area of the ordinary hose layer, reducing the local protrusions formed by the hose connector directly pressing on the middle of the ordinary hose layer, and avoiding interference from local high points to the continued flat stacking of subsequent hoses; secondly, it allows the hose connector to move down synchronously with the descent of the hose plate 52, thereby reducing the pulling phenomenon on the hose connector caused by the overall downward movement of the hose layer, and thus reducing the possibility of the hose connector disturbing the adjacent hose layers. Meanwhile, the receiving belt 44 is made of flexible material, giving it a certain degree of elasticity when receiving hose connectors. This facilitates the insertion of the hose connectors into the receiving belt 44 and provides a gentle constraint after insertion, preventing rigid clamping structures from causing hard compression to the hose connectors or adjacent hoses. Through the above design, this embodiment can effectively balance the individual placement of hose connectors, synchronous changes in layer positions, and the overall flatness when subsequent hoses are stacked.
[0022] Further as Figure 6 As shown, it is worth noting that the storage cavity is provided with a plurality of abutment rods 61, which are located on both sides of the storage belt 44 and are arranged in pairs symmetrically. The ends of the abutment rods 61 are rotatably connected to abutment wheels 62, which abut against the storage belt 44. It should be noted that the storage belt 44 is made of flexible material. While this facilitates the insertion and containment of the hose connector within the storage belt 44, without proper support, the belt can easily deform significantly when the hose connector enters, thus affecting the stability of the connection. Therefore, several pairs of symmetrically distributed abutment rods 61 are arranged on both sides of the storage belt 44 within the storage cavity. Abutment wheels 62 are rotatably connected to the ends of the abutment rods 61, allowing the abutment wheels 62 to provide abutment support on both sides of the storage belt 44. In actual operation, when the hose connector is guided into the storage belt 44 after being bypassed by the laying device 20, the storage belt 44 will expand and deform to a certain extent to both sides under the pressure of the connector. The abutment wheels 62 on both sides provide limiting support to the outer side of the storage belt 44, thereby preventing excessive opening of the storage belt 44 and ensuring that the storage belt 44 maintains a relatively stable containment profile when accommodating the connector. Meanwhile, since the abutment wheel 62 and the storage belt 44 have a rolling abutment relationship, when the storage belt 44 moves with the chain 43, or when it undergoes relative displacement with the abutment wheel 62 during compression deformation, the abutment wheel 62 can reduce frictional resistance by rolling, avoiding wear or jamming caused by rigid pressure. In this way, the abutment rod 61 and the abutment wheel 62 can provide auxiliary support and guidance for the storage belt 44 without hindering its normal deformation, ensuring that it has a certain degree of elasticity when receiving the hose connector, without becoming unstable and deformed due to excessive force.
[0023] Further as Figure 7 As shown, it is worth noting that the driving device 53 includes: The guide rail 531 is fixedly connected to the carriage 10. The water hose plate 52 is slidably connected to the guide rail 531. A servo motor 532 is provided on the partition plate 51. The end of the output shaft of the servo motor 532 is fixedly connected to the connecting rod 41. It should be noted that the guide rail 531 is fixedly installed inside the carriage 10. Therefore, the guide rail 531 can provide vertical guidance for the hose plate 52, so that the hose plate 52 maintains a relatively stable movement trajectory during lifting and lowering, and avoids significant tilting or shaking of the hose plate 52 under load. After the servo motor 532 is started, its output shaft drives the connecting rod 41 fixedly connected to it to rotate. The chain teeth 42 fixedly connected in the middle of the connecting rod 41 rotate accordingly. Since the chain teeth 42 are connected by the chain 43, the chain 43 circulates in the corresponding direction. Since a round rod 46 is provided between the chain 43 and the hose plate 52, and one end of the round rod 46 is fixedly connected to the chain 43 and the other end is fixedly connected to the hose plate 52, when the chain 43 is running, the round rod 46 can drive the hose plate 52 to move vertically up or down along the guide rail 531. In actual operation, as the recovered hoses are continuously transported to the corresponding storage chamber, servo motor 532 drives chain 43 to move gradually, causing the hose plate 52 to slowly move downwards, thus making room for subsequent hoses to be placed. When it is necessary to re-lay the hoses, servo motor 532 can rotate in the opposite direction, driving chain 43 to move in the opposite direction, causing the hose plate 52 to move upwards, thus facilitating the gradual lifting of the hoses in the storage chamber to a height more suitable for clamping and unloading by the laying device 20. In this way, the drive device 53 can achieve controllable lifting and lowering of the hose plate 52, and coordinate with the operation of the aforementioned storage mechanism 40, so that the ordinary hose layer and hose connectors stored in the storage chamber maintain a relatively coordinated state during position changes.
