[0026] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0027] like Figure 1 , Figure 2 , Figure 3As shown, the water hose laying vehicle provided by the embodiment of the present invention includes a vehicle body 4, a guide device 2 is arranged on the compartment of the vehicle body 4, a water squeezing device 1 is arranged at the front end of the guide device 2, and a water hose receiving device 3 is arranged at the rear end of the guide device 2. The water squeezing device 1 can squeeze water out of the water hose 5, and the guide device 2 can drive the water hose 5 to move along the axial direction of the water hose receiving device 3, and guide the water hose 5 to the water hose receiving device 3 to realize the storage of the water hose 5.
[0028] The size of the vehicle body 4 of the embodiment of the present invention can be selected according to actual needs. For example, for old residential areas with complex road conditions, the vehicle body 4 can be a small vehicle, which is convenient for vehicles to shuttle and quickly lay water hoses 5. For scenes where long-distance water hoses 5 need to be laid, the vehicle body 4 can choose a medium or large vehicle, and the corresponding water hose storage device 3 can be set to multiple, which is convenient for long-distance laying of water hoses 4. The water hose laying vehicle provided by the embodiment of the present invention is particularly suitable for small vehicles. Compared with existing large water hose laying vehicles, it has the characteristics of miniaturization and flexible movement.
[0029] Furthermore, the hose storage device 3 includes a reel bracket 32 fixedly connected to the carriage and a reel 31 rotatably connected to the reel bracket 32, and the reel 31 is driven to rotate by the reel driving device 33 to drive the hose 5 on the reel 31 to be retracted and released. Baffles are provided on both sides of the reel 31 to limit the axial position of the hose 5 on the reel 31. The reel driving device 33 of the embodiment of the present invention can be in the form of a combination of a drive motor and a belt, a combination of a drive motor and a gear, or a transmission device driven by the power of the vehicle during driving and other driving forms to drive the rotation of the reel 31, which can be selected according to the requirements of the spatial structure, and is not specifically limited by the present invention.
[0030] When laying the water hose 5, connect the water hose 5 on the car to the fire truck or fire hydrant, and while the vehicle body 4 is moving forward, drive the reel 31 to rotate through the reel drive device 33 to release the water hose 5. When the length of the water hose 5 reaches the required length, open the joint of the water hose 5. It should be noted that the fire hose 5 is usually a section of water hose with a fixed length, including a water hose body and water hose joints at both ends of the water hose body. The sections of water hose are connected through the water hose joints to form a fire hose 5 of the required length. In the embodiment of the present invention, the sections of water hose are connected and stored on the reel 31 in advance, and when performing firefighting operations, the connected water hose 5 can be directly pulled out and connected, which saves precious time for firefighting operations. It should be noted that the water hose 5 in the figure is only used to illustrate the path of the water hose 5 when the water hose 5 is stored, and does not represent the real water hose structure. In a specific embodiment of the present invention, a small hose laying vehicle can carry a 1500m long hose 5. A 1500m long hose usually requires 20-30 firefighters to carry it. Therefore, the hose laying vehicle provided in the embodiment of the present invention greatly reduces the workload of firefighters.
[0031] Furthermore, the guide device 2 includes a guide bracket 21 arranged on the carriage, and one or more guide wheels 22 are arranged on the guide bracket 21. A water hose channel is formed between the guide wheel 22 and the guide bracket 21, and the movement direction of the water hose 5 is limited by the water hose channel.
[0032] Furthermore, the guide bracket 21 is disposed at the top or side of the vehicle body 4 , one end of the guide bracket 21 is fixedly connected to the vehicle compartment, and the other end of the guide bracket 21 extends to the front direction of the vehicle.
[0033] In a specific embodiment of the present invention, one end of the guide bracket 21 is fixedly connected to the top of the carriage, and the other end of the guide bracket 21 extends to the top of the front of the vehicle, so that when the water hose 5 is stored, the water hose 5 can be stored by moving the vehicle forward. Of course, the guide bracket 21 can also be set on the side of the carriage 41, and when the water hose 5 is stored, the water hose 5 is stored by driving the vehicle in a direction parallel to the water hose, so that the driver's field of vision will not be affected when the water hose 5 is stored.
[0034] Furthermore, the guide device 2 also includes an axially movable guide device 23 arranged in the car. The axially movable guide device 23 controls the water hose to move back and forth in the axial direction of the reel 31 of the water hose storage device when the water hose is stored, so that the water hose 5 can be reciprocated along the axial direction of the water hose storage device (that is, the axial direction of the reel) and wound on the reel 31.
[0035] The axial movement guide device 23 of a specific embodiment of the present invention is as follows Figure 4 As shown, it includes an axial track 231 parallel to the axial direction of the water hose storage device 3 and a limiting guide device 232 slidably connected to the axial track 231. The water hose passes through the limiting guide device 232, and the axial moving drive device 233 drives the limiting guide device 232 to move on the axial track 231 to drive the water hose 5 to reciprocate along the axial direction of the water hose storage device 3.
[0036] The axial track 231 can be a transmission device in any structural form such as a synchronous belt, a gear rack, and a ball screw to drive the limiting guide device 232 to move under the drive of the axial movement drive device 233. When the hose is stored, the moving speed of the limiting guide device 232 and the rotation speed of the reel 31 are limited so that the hose can be evenly wound on the rotating shaft of the reel 31.
[0037] It should be noted that the installation positions of the guide bracket 21, the reel 31 and the axial rail 231 mentioned in the embodiment of the present invention are set accordingly, and the reel of the reel 31 can be installed horizontally or vertically. When the guide bracket 21 is installed on the top of the car, the reel 31 is preferably installed horizontally, and when the guide bracket 21 is installed on the side of the car, the reel 31 is preferably installed vertically. This can avoid the problem of excessive resistance caused by excessive bending angle of the water hose 5.
[0038] Furthermore, a hose channel is provided inside the limiting guide device 232, and rollers are provided on the side walls. When the hose passes through, it contacts the rollers, so as to reduce the resistance of the hose when passing through the limiting guide device 232 when the hose is stored. In addition, since the limiting guide device 232 drives the hose 5 to reciprocate along the axial direction of the hose storage device 3, the relative displacement of the hose 5 and the limiting guide device 232 in the axial direction will inevitably occur during the movement. The rollers are provided on the side walls of the limiting guide device 232, which can effectively reduce the collision and friction between the hose 5 and the side walls of the frame of the limiting guide device 232.
[0039] Furthermore, the guide device 2 further includes rollers 24 on both sides or one side of the axially movable guide device 23, and the rollers 24 are parallel to the axial guide rails 231 of the axially movable guide device 23 to provide vertical support for the hose 5. This reduces the resistance when the hose is stored. The length of the rollers 24 is preferably equivalent to the axial length of the reel 31, so as to provide vertical support for the reel 31 in the entire axial direction.
[0040] The hose laying vehicle of the present invention comprises a vehicle body, a guide device 2 is arranged on the carriage of the vehicle body, a water squeezing device 1 is arranged at the front end of the guide device 2, and a hose 5 receiving device 3 is arranged at the rear end of the guide device 2. The water squeezing device 1 can squeeze out the water in the hose 5, and the guide device 2 can drive the hose 5 to move along the axial direction of the hose receiving device 3, and guide the hose 5 to the hose receiving device 3 to achieve the storage of the hose. The hose laying vehicle provided by the present invention can quickly lay and pick up hoses when fire fighters perform firefighting operations, which is conducive to taking water from a distant water source to perform firefighting operations. It is very suitable for old residential areas and forest fires, and can reduce the work intensity of fire fighters.
[0041] Furthermore, the hose laying vehicle of the embodiment of the present invention further comprises a water squeezing device 1 of the following embodiment, such as Figure 5 , Figure 6As shown, the water squeezing device 1 of the embodiment of the present invention is used to perform water squeezing operations on the fire hose 5, including a fixed first water squeezing wheel 12 and a second water squeezing wheel 13 that can move relative to the first water squeezing wheel 12. When the hose body passes through, the gap between the first water squeezing wheel 12 and the second water squeezing wheel 13 forms a water squeezing channel to squeeze out the water in the hose 5. When the hose joint passes through, the second water squeezing wheel 13 moves relative to the first water squeezing wheel 12, so that the gap between the first water squeezing wheel 12 and the second water squeezing wheel 13 becomes wider for the hose joint to pass through.
[0042] Furthermore, the water squeezing device 1 specifically includes a water squeezing device side plate 11, on which a first water squeezing wheel 12 is fixedly installed, and a water squeezing arm 14 is movably connected to the water squeezing device side plate 11 via a first rotating shaft 141, and a second water squeezing wheel 13 is arranged on the water squeezing arm 14, and when the water squeezing arm 14 rotates, the second water squeezing wheel 13 is driven to move relative to the first water squeezing wheel 11.
[0043] When squeezing water from the water hose 5, the remaining water in the water hose 5 is squeezed out by utilizing the deadweight of the second water squeezing wheel 14. When the water hose joint passes through, the second water squeezing wheel 13 is driven to rotate around the first rotating shaft 141 to increase the gap between the first water squeezing wheel 12 and the second water squeezing wheel 13 to allow the water hose joint to pass through.
[0044] After the hose joint passes through, the second squeezing wheel 14 is quickly returned to the upper end of the first squeezing wheel 12 under the action of the second squeezing wheel 13's own weight to realize the squeezing operation of the hose 5. It can be understood that an elastic member is also provided between the first rotating shaft 141 and the side plate 11 of the squeezing device to prompt the second squeezing wheel 13 to quickly fall back to the upper end of the first squeezing wheel 12 after the hose joint passes through. The elastic member can be a torsion spring. The present invention can continuously and uninterruptedly perform the squeezing operation on the hose by rotating the second squeezing wheel 13 under the drive of the squeezing arm 14, thereby improving the squeezing efficiency.
[0045] Furthermore, the water squeezing device 1 also includes a locking unit and a switch unit. The locking unit is used to lock the position of the second water squeezing wheel when the water hose body passes through, and the switch unit can control the locking unit to open the locking unit when the water hose joint passes through.
[0046] Specifically, when the water hose body passes through the water squeezing device 1, the position of the water squeezing arm 14 is locked to limit the gap between the first water squeezing wheel 12 and the second water squeezing wheel 13, thereby providing a constant water squeezing pressure to the water hose. When the water hose joint passes through the water squeezing device 1, the water squeezing arm locking device is triggered to open to release the position lock of the water squeezing arm 14, and the water squeezing arm 14 is driven by the water hose joint to rotate around the first rotating shaft 141 to allow the water hose joint to pass through the water squeezing device 1. The locking unit and the switch unit of the embodiment of the present invention constitute a water squeezing arm locking device, which can continuously supply the water hose 5 to pass through the water squeezing device 1 while fully squeezing out the water in the water hose body, thereby improving the water squeezing efficiency.
[0047] In a specific embodiment of the present invention, the locking unit and the switch unit are as follows Figure 5 , Figure 6 As shown, the locking unit includes a locking hook 15 and a locking column 142. The locking hook 15 is connected to the side plate 11 of the water squeezing device through a second rotating shaft 152. The locking column 142 is arranged on the water squeezing arm 14. The hook structure 151 at one end of the locking hook 15 cooperates with the locking column 142 to realize the position locking of the second water squeezing wheel 13.
[0048] Further, the switch unit includes a hose joint baffle 16 disposed on the second rotating shaft 152, and the hose joint baffle 16 is disposed at the proximal end of the hose inlet relative to the locking hook 15. When the hose joint passes through, the hose joint baffle 16 is driven to rotate forward, so that the locking hook 15 rotates around the second rotating shaft 152 to make the hook structure 151 at one end of the locking hook 15 disengage from the locking column 142, so as to release the locking state of the locking hook 151 and the locking column 142, so that the hose joint can smoothly pass through the water squeezing device 1. The hose inlet in the embodiment of the present invention is the entrance position when the hose 5 enters the water squeezing device 1.
[0049] Furthermore, a return baffle 17 is provided on the side plate 11 of the water squeezing device, and the return baffle 17 is provided at the proximal end of the water hose inlet relative to the water hose joint baffle 16 to limit the return position of the water hose joint baffle 16. In addition, an elastic member is also provided between the second rotating shaft 152 and the side plate 11 of the water squeezing device to make the locking hook 15 fall back quickly after the water hose joint passes through the water squeezing device 1, wherein the elastic member can be a torsion spring.
[0050] Furthermore, a tugboat 111 is also provided at the front end of the first squeezing wheel 12 and the second squeezing wheel 13 to drag the water hose 5 to the entrance of the gap between the first squeezing wheel 12 and the second squeezing wheel 13. When the water hose is stored, the water hose is dragged to the vicinity of the gap between the first squeezing wheel 12 and the second squeezing wheel 13, which plays a certain buffering role for the storage of the water hose and reduces the resistance generated by the water hose directly passing through the first squeezing wheel and the second squeezing wheel.
[0051] Furthermore, a front guide wheel 112 is also provided at the front end of the first squeezing wheel 12 and the second squeezing wheel 13. The front guide wheel 112 is connected to the side plate 11 of the squeezing device through a connecting seat. The front guide wheel 112 is a roller structure arranged left and right and / or up and down to limit the water hose entrance to the middle channel of the front guide wheel 112. Before the water hose enters the gap between the first squeezing wheel 12 and the second squeezing wheel 13, the water hose is limited to the space range of the first squeezing wheel and the second squeezing wheel. In a preferred embodiment of the present invention, the front guide wheel 112 is closer to the proximal end of the water hose entrance than the tugboat 111.
[0052] The squeezing arm locking device of another embodiment of the present invention is as follows Figure 7 As shown, the locking unit includes an electromagnet 19 respectively arranged on the squeezing arm 14 and the side plate 11 of the squeezing device, and the switch unit is an induction switch arranged at the proximal end of the water hose inlet relative to the second squeezing wheel 13. The induction switch is triggered to cut off the power of the electromagnet when the water hose joint passes through. In addition, the induction switch can also be a laser induction switch. When the water hose joint passes through the laser induction switch, the laser induction switch is activated to cut off the power of the electromagnet 19, and the squeezing arm 14 rotates to allow the water hose joint to pass through.
[0053] The squeezing arm locking device of another embodiment of the present invention is as follows Figure 8 As shown, it includes an elastic connecting rod 18 connected between the water squeezing arm 14 and the side plate 11 of the water squeezing device. The elastic connecting rod 18 is arranged at the far end of the water hose inlet relative to the second water squeezing wheel 13. When the water hose body passes through, the elastic force of the elastic connecting rod 18 squeezes the water squeezing arm 14 to achieve position locking of the second water squeezing wheel 13. When the water hose joint passes through, the water hose joint squeezes the elastic connecting rod 18 to achieve movement of the second water squeezing wheel 13 relative to the first water squeezing wheel 12.
[0054] The squeezing device provided by the present invention specifically comprises a first squeezing wheel 12 that is fixedly arranged and a second squeezing wheel 13 that can move relative to the first squeezing wheel 12. When the hose body passes through, the gap between the first squeezing wheel 12 and the second squeezing wheel 13 forms a squeezing channel. When the hose joint passes through, the second squeezing wheel 13 moves relative to the first squeezing wheel 12, so that the gap between the first squeezing wheel 12 and the second squeezing wheel 13 becomes wider for the hose joint to pass through. When the fire hose is stored, the remaining water in the fire hose can be fully squeezed out and the hose joint can be ensured to pass quickly and smoothly, thereby improving the efficiency of the hose storage.
