Description

Technical Field

[0001] This utility model relates to the field of water pipe support technology for sprinkler trucks, and in particular to a water pipe support mechanism for sprinkler trucks. Background Technology

[0002] Water sprinkler trucks, also known as spray trucks, multi-functional water sprinkler trucks, landscaping water sprinkler trucks, water tankers, water trucks, and washing trucks, are suitable for washing various road surfaces, watering trees, green belts, and lawns, as well as for road and factory construction and high-rise building cleaning.

[0003] The water hoses (such as suction hoses and spray hoses) of sprinkler trucks need to be kept stable during driving or operation to avoid tangling, dragging on the ground or collisions. Therefore, brackets are needed to fix and store the water hoses to ensure safe and convenient operation. The water hoses of sprinkler trucks are usually about 5 meters to 30 meters long. Common water hoses can be wound on reels to save space and make them easy to put away and take out. In addition, simple hooks or slots can be used to fix the direction of the water hoses and prevent them from shaking.

[0004] A search revealed that Chinese utility model patent CN204780745U discloses a water hose rack for a sprinkler truck, comprising a hose rack beam, hose rack ribs, a support frame, fixing bolts, a central shaft, and an auxiliary wrench. The key feature is that there are two symmetrical support frames, fixed to the sprinkler truck body by fixing bolts. The central shaft is located at the midpoint between the tops of the two symmetrical support frames. There are also two symmetrical hose rack beams, positioned at both ends of the central shaft. Multiple hose rack ribs are arranged between the hose rack beams. An auxiliary wrench is located between the central shaft and the outer support frame, and the auxiliary wrench is connected to the central shaft by a detachable one-way free wheel. This application utilizes a reel-type hose rack to assist in storing the water hose. However, after the hose is reeled in, it must be unwound before use. For longer hoses, the reeling and unwinding process can be time-consuming and laborious, potentially leading to inconvenience due to untimely reeling or improper operation, thus affecting the sprinkler truck's working efficiency. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a water pipe support mechanism for a sprinkler truck, and the main technical problem to be solved is how to ensure the convenient storage and use of the water pipe.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A water pipe support mechanism for a sprinkler truck includes a housing and a water pipe mounted on the sprinkler truck. The housing is provided with a support mechanism and an adjustment mechanism. The adjustment mechanism includes a telescopic arm and a drive assembly for driving the telescopic arm to extend and retract. The telescopic arm includes a plurality of telescopic joints that are sequentially connected. Each telescopic joint is provided with a lifting ring for fixing the water pipe. The telescopic arm adjusts the spacing of the lifting rings by the extension and retraction of the telescopic joints to bend and straighten the water pipe. The adjustment mechanism includes a connecting strap for pulling the support of the telescopic arm.

[0007] Furthermore, the drive assembly includes a rigid chain actuator disposed inside the housing, with a connecting piece fixedly connected to one end of the rigid chain of the rigid chain actuator.

[0008] Furthermore, the telescopic arm is fixedly connected at the bottom between the housing and the connecting plate, and several telescopic joints are all rectangular in shape.

[0009] Furthermore, connecting plates are fixedly connected to the bottom ends of several expansion joints, and lifting rings are fixedly connected to the bottom ends of the connecting plates.

[0010] Furthermore, a fixed frame is fixedly connected to the top of the casing, and a pulley is rotatably connected at the top between the inner walls on both sides of the fixed frame, with a connecting belt wrapped around the outside of the pulley.

[0011] Furthermore, a connecting shaft is fixedly connected at the bottom between the inner walls on both sides of the fixed frame, and a winding cylinder is rotatably connected between the inner walls on both sides of the fixed frame at the outside of the connecting shaft.

[0012] Furthermore, a torsion spring is fixedly connected between the connecting shaft and the winding cylinder, and the two ends of the connecting belt are fixedly connected to the winding cylinder and the connecting piece, respectively.

[0013] Furthermore, support rods are fixedly connected to the four corners of the bottom outer side of the casing, and base plates are fixedly connected to the bottom ends of the four support rods.

[0014] Furthermore, a base is rotatably connected to the bottom end of the base plate, and threaded through holes are provided on both sides of the base plate. Bolts are threadedly connected to the base plate at the threaded through holes.

[0015] The beneficial effects of this utility model are as follows: 1. This application adjusts the spacing of several lifting rings by extending or shortening the telescopic arm. When the spacing is reduced, the water pipe can be bent in a serpentine shape for storage, while when the spacing is increased, the water pipe can be straightened for water flow. This ensures the convenience of storing and using the water pipe and avoids affecting the working efficiency of the sprinkler truck due to untimely extension or retraction. In addition, the connecting strap can provide support for the water pipe by pulling its end when the telescopic arm is extended, thus ensuring the stability of the water pipe during use. 2. As the telescopic arm extends, it pulls on the connecting belt, causing it to rotate around the cylinder. This causes the torsion spring to undergo elastic deformation and accumulate elastic force. The reverse pull of this elastic force on the connecting belt provides support for the telescopic arm to support the water pipe. Furthermore, the longer the telescopic arm extends, the greater the length the connecting belt is pulled. Therefore, the greater the degree of elastic deformation of the torsion spring caused by the rotation around the cylinder, the more stable the telescopic arm and the water pipe at its bottom can be maintained. 3. By setting a base and bottom plate that can rotate relative to each other, the orientation of the telescopic arm can be adjusted by rotating the bottom plate, thus controlling the direction of its extension and avoiding the phenomenon that the water hose cannot be adjusted for use due to space limitations.

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0019] Example 1 See attached document Figure 1-3This application provides a water pipe support mechanism for a sprinkler truck, including a housing 1 and a water pipe 601 mounted on the sprinkler truck. The housing 1 can be fixedly connected to the side of the sprinkler truck's water tank. In this case, the telescopic arm 7 can be adjusted to extend along the axial direction of the water tank, thus eliminating the need for excessive extension space. The housing 1 is equipped with a support mechanism and an adjustment mechanism. The adjustment mechanism includes the telescopic arm 7 and a drive assembly for driving the telescopic arm 7 to extend and retract. The telescopic arm 7 includes several telescopic joints 701 sequentially connected. Each telescopic joint 701 has a hanging ring 6 for fixing the water pipe 601. The telescopic arm 7 adjusts the spacing of the hanging rings 6 by the extension and retraction of the telescopic joints 701 to bend and straighten the water pipe 601, facilitating the retraction and straightening of the water pipe 601 after bending. The adjustment mechanism includes a connecting strap 3 for pulling and supporting the telescopic arm 7, thus providing a pulling support effect for the extended telescopic arm 7 to ensure the stability of the water pipe 601 located at the bottom.

[0020] When using this device, the water pipe 601 can be inserted into the inside of the hanging ring 6 and fixed, and the hanging ring 6 can be equidistantly placed on the outside of the water pipe 601. When the telescopic arm 7 is in the retracted state, several hanging rings 6 will be close to each other, so that the water pipe 601 can bend in a serpentine manner to achieve storage.

[0021] Preferably, the drive assembly includes a rigid chain actuator 2 disposed inside the housing 1. The rigid chain actuator 2 drives the rigid chain to produce linear motion and has a reverse self-locking effect. This is because it is usually equipped with a brake motor as the power source for driving the rigid chain. After the brake motor is de-energized, its brake device will immediately lock the drive shaft to avoid reverse retraction due to external force. Therefore, after the actuator drives the rigid chain to produce linear motion to pull the connecting belt 3 and cause the torsion spring 802 to produce elastic deformation, the elastic force of the torsion spring 802 will not cause the connecting belt 3 to pull the rigid chain back into the actuator. Thus, the stability of the telescopic arm 7 after extension can be guaranteed. A connecting piece 4 is fixedly connected to one end of the rigid chain of the rigid chain actuator 2.

[0022] Preferably, the telescopic arm 7 is fixedly connected to the bottom end between the housing 1 and the connecting piece 4. Several telescopic joints 701 are all cuboid in shape to prevent relative rotation between the telescopic joints 701, thus avoiding any space or possibility for the water pipe 601 to swing. A connecting plate 5 is fixedly connected to the bottom end of each telescopic joint 701, and a lifting ring 6 is fixedly connected to the bottom end of the connecting plate 5.

[0023] When the water pipe 601 is needed, the rigid chain actuator 2 can be activated to push the connecting piece 4 to move, which in turn pulls the telescopic joint 701 to adjust the extension of the telescopic arm 7. At this time, the spacing of the lifting rings 6 on each telescopic joint 701 will increase, so that the water pipe can be pulled straight to facilitate the flow of water into it for use.

[0024] Preferably, a fixing frame 8 is fixedly connected to the top of the housing 1, and a pulley 9 is rotatably connected at the top between the inner walls of both sides of the fixing frame 8. A connecting belt 3 is wound around the outside of the pulley 9. A connecting shaft 801 is fixedly connected to the bottom between the inner walls of both sides of the fixing frame 8, and a winding cylinder 10 is rotatably connected between the inner walls of both sides of the fixing frame 8 at the outside of the connecting shaft 801. A torsion spring 802 is fixedly connected between the connecting shaft 801 and the winding cylinder 10, and the two ends of the connecting belt 3 are fixedly connected to the winding cylinder 10 and the connecting piece 4, respectively.

[0025] During the extension of the telescopic arm 7, the connecting piece 4 will also pull the connecting belt 3 to extend, and the connecting belt 3 will pull the cylinder 10 to rotate, causing the torsion spring 802 to undergo elastic deformation and accumulate elastic force. By using this elastic force to pull the connecting belt 3 in the opposite direction, the end of the telescopic arm 7 can be pulled to provide support for it, thereby ensuring the stability of the water pipe 601 at its bottom.

[0026] Furthermore, since the extension length of the telescopic arm 7 is greater, the angle at which the connecting belt 3 rotates around the cylinder 10 is greater, and the degree of elastic deformation of the torsion spring 802 is greater, so it can generate a greater elastic force to pull the telescopic arm 7. That is, the longer the telescopic arm 7 is extended, the greater the support force that the torsion spring 802 can provide for it, thereby ensuring the support function of the telescopic arm 7 for the water pipe 601.

[0027] Example 2 See attached document Figure 4 This application provides a water hose support mechanism for a sprinkler truck. Compared to embodiment 1, to facilitate adjustment of the extension direction of the telescopic arm 7, support rods 11 are fixedly connected to the four corners of the bottom outer side of the housing 1, and base plates 12 are fixedly connected to the bottom ends of the four support rods 11. With the base 14 and base plate 12 provided, this device can be installed on the rear working platform of the sprinkler truck, and the base 14 can be fixedly connected to the platform to ensure that the base 14 and base plate 12 can provide sufficient support for the telescopic arm 7. In this case, the telescopic arm 7 can have a larger range of orientation adjustment, so the extension of the telescopic arm 7 can be adjusted to use the water hose according to the location of the sprinkler truck, without affecting other things.

[0028] Preferably, the bottom end of the base plate 12 is rotatably connected to the base 14, and threaded through holes are provided on both sides of the base plate 12. Bolts 13 are threadedly connected to the base plate 12 at the threaded through holes.

[0029] When the space where the water truck is located is limited, after loosening the bolt 13, the base plate 12 can be adjusted by moving the support rod 11, which in turn drives the telescopic arm 7 to deflect and adjust its orientation, so as to ensure that it has enough space to straighten the water pipe 601 for use; after adjusting the deflection of the telescopic arm 7, simply tighten the bolt 13 to fix the adjusted orientation of the telescopic arm 7.

[0030] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
