In the following description, specific details such as specific configuration and assembly are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0027] The hose cart is used to assist workers in laying and recycling hoses, and can be moved for easy transfer. The hose tools currently on the market are large in size, require a large space, and are not convenient for transportation. In addition, the rolled hose is heavy, so it still takes a lot of manpower to take the hose roll from the hose tool. In view of this, the present application provides a frame of a hose cart to improve the above problems. The frame of the hose cart provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0028] refer to Figure 1 and Figure 2 The frame of the water hose vehicle includes a frame body 10, a bottom bracket 20, a first connecting rod 30, a second connecting rod 40, and a telescopic actuator 50. Among them, a front wheel 11 is provided at the bottom of the frame body 10. The bottom bracket 20 is rotatably connected to the frame body 10 and is located below the frame body 10, and a rear wheel 21 is provided on the bottom bracket 20. The first end of the first connecting rod 30 is rotatably connected to the frame body 10, the first end of the second connecting rod 40 is rotatably connected to the bottom bracket 20, and the second end of the first connecting rod 30 and the second end of the second connecting rod 40 are rotatably connected together. The telescopic actuator 50 is used to telescopically drive the first connecting rod 30 and the second connecting rod 40 to rotate, so that the frame body 10 rotates up and down relative to the bottom bracket 20 to adjust the angle position. The first connecting rod 30, the second connecting rod 40, the frame body 10, and the bottom bracket 20 constitute a connecting rod mechanism, and are driven by the telescopic actuator 50.

[0029] Specifically, the first link 30 is rotatably connected to the frame body 10, the second link 40 is rotatably connected to the bottom bracket 20, and the first link 30 and the second link 40 are rotatably connected together. The bottom bracket 20 is located below the frame body 10, and the two can rotate relative to each other. The first link 30 and the second link 40 are arranged between the bottom bracket 20 and the frame body 10, and are used to adjust the angle between the bottom bracket 20 and the frame body 10 under the drive of the telescopic actuator 50.

[0030] When the frame body 10 needs to be raised, the telescopic actuator 50 is adjusted. Under the telescopic drive of the telescopic actuator 50, the angle between the first connecting rod 30 and the second connecting rod 40 is increased. Figure 1 As shown, when the angle between the first link 30 and the second link 40 increases to the maximum angle θ1, the frame body 10 is lifted to the maximum height. In this state, the operator can lay and recover the hose.

[0031] When the frame body 10 needs to be lowered, the telescopic actuator 50 is adjusted, and the angle between the first connecting rod 30 and the second connecting rod 40 is reduced under the telescopic drive of the telescopic actuator 50. Figure 2 As shown, when the angle between the first link 30 and the second link 40 is reduced to the minimum angle θ2, the frame body 10 is lowered to the minimum height. In this state, the operator can easily take out the hose roll, reducing the use of manpower. In addition, in this state, the frame body 10 and the bottom bracket 20 are folded together at the minimum angle θ2, which takes up less space and is more convenient for transportation.

[0032] The telescopic actuator 50 drives the first connecting rod 30 and the second connecting rod 40 to rotate through a telescopic action. In the embodiment of the present application, the telescopic actuator 50 can be an electric actuator, a pneumatic actuator, or a hydraulic actuator, specifically an electric cylinder, a gas cylinder, an oil cylinder, etc., and a suitable actuator can be selected according to the specific usage scenario.

[0033] Furthermore, a front wheel 11 is arranged on the frame body 10, and a rear wheel 21 is arranged on the bottom bracket 20. The front wheel 11 and the rear wheel 21 constitute a walking device. When the water hose is rolled up, the water hose vehicle can be moved in the direction of the water hose to avoid dragging the water hose. In one embodiment, the rear wheel 21 is set as a universal wheel, which is convenient for steering and more flexible when used.

[0034] In one embodiment, the front wheels 11 include a first front wheel 12 located on the left side, a second front wheel 13 located on the right side, and a wheel axle for mounting the first front wheel 12 and the second front wheel 13 .

[0035] refer to Figure 3-Figure 5 In one embodiment of the present application, the bottom bracket 20 includes a first bottom arm 22 and a second bottom arm 23. The first bottom arm 22 is located on the left side, and the second bottom arm 23 is located on the right side, wherein the first bottom arm 22 and the second bottom arm 23 are independently connected to the frame body 10, and the first bottom arm 22 is provided with a first rear wheel 24, and the second bottom arm 23 is provided with a second rear wheel 25. Furthermore, the first bottom arm 22 and the second bottom arm 23 are respectively provided with a first connecting rod 30, a second connecting rod 40, and a telescopic actuator 50.

[0036] like Figure 3As shown, the first bottom support arm 22 and the second bottom support arm 23 are independent of each other, and each is provided with a first connecting rod 30, a second connecting rod 40, and a telescopic actuator 50. The telescopic actuators 50 on the left and right sides can synchronously drive the frame body 10 to rotate, lift or lower.

[0037] refer to Figure 3 and Figure 4 When the frame body 10 needs to be raised, the telescopic actuators 50 on the left and right sides are adjusted. Under the common telescopic drive of the telescopic actuators 50 on both sides, the angle between the first connecting rod 30 and the second connecting rod 40 on both sides increases, such as Figure 3 and Figure 4 As shown, when the angle between the first connecting rod 30 and the second connecting rod 40 on both sides increases to the maximum angle, the frame body 10 is lifted to the maximum height. In this state, the operator can lay and recover the water hose.

[0038] refer to Figure 5 When the frame body 10 needs to be lowered, the telescopic actuators 50 on the left and right sides are adjusted. Under the telescopic drive of the telescopic actuators 50 on both sides, the angle between the first connecting rod 30 and the second connecting rod 40 on both sides is reduced. Figure 2 As shown, when the angle between the first connecting rod 30 and the second connecting rod 40 on both sides is reduced to the minimum angle, the frame body 10 is lowered to the minimum height. In this state, the operator can easily take out and put out the hose roll, reducing the use of manpower. In addition, in this state, the frame body 10 and the first bottom support arm 22 and the second bottom support arm 23 are folded together at the minimum angle, which takes up less space and is more convenient for transportation.

[0039] In one embodiment of the present application, the first end of the telescopic actuator 50 is rotatably connected to the frame body 10 or the bottom bracket 20, and the second end of the telescopic actuator 50 is rotatably connected to the first link 30 or the second link 40. Under this structure, when the telescopic actuator 50 performs a telescopic action, the angle between the first link 30 and the second link 40 also changes accordingly, and the angle between the frame body 10 and the bottom bracket 20 also changes accordingly, so that the height of the frame body 10 is raised or lowered.

[0040] Specifically, the telescopic actuator 50 includes the following four arrangements: the first arrangement is: the first end of the telescopic actuator 50 is connected to the frame body 10, and the second end is connected to the first connecting rod 30. The second arrangement is: the first end of the telescopic actuator 50 is connected to the frame body 10, and the second end is connected to the second connecting rod 40. The third arrangement is: the first end of the telescopic actuator 50 is connected to the bottom bracket 20, and the second end is connected to the first connecting rod 30. The fourth arrangement is: the first end of the telescopic actuator 50 is connected to the bottom bracket 20, and the second end is connected to the second connecting rod 40.

[0041] In one embodiment of the present application, the first end of the telescopic actuator 50 is rotatably connected to the frame body 10 or the bottom bracket 20, and the second end of the telescopic actuator 50, the second end of the first link 30, and the second end of the second link 40 form a composite hinge. Under this structure, when the telescopic actuator 50 performs a telescopic action, the angle between the first link 30 and the second link 40 also changes accordingly, and the angle between the frame body 10 and the bottom bracket 20 also changes accordingly, so that the height of the frame body 10 is raised or lowered.

[0042] Specifically, the telescopic actuator 50 also includes the following two arrangements. The fifth arrangement is: the first end of the telescopic actuator 50 is connected to the frame body 10, and the second end forms a composite hinge with the second end of the first link 30 and the second end of the second link 40. The sixth arrangement is: the first end of the telescopic actuator 50 is connected to the bottom bracket 20, and the second end forms a composite hinge with the second end of the first link 30 and the second end of the second link 40.

[0043] In a specific embodiment, if Figure 1 As shown, the main body of the telescopic actuator 50 is installed on the frame body 10 , and the telescopic end thereof forms a composite hinge with the second end of the first link 30 and the second end of the second link 40 .

[0044] In the embodiment of the present application, part or all of the rotatable connection relationship is set as a hinge relationship. Specifically, one or more of the connection between the first connecting rod and the second connecting rod, the connection between the first connecting rod and the frame body, the connection between the second connecting rod and the bottom bracket, the connection between the frame body and the bottom bracket, and the connection between the two ends of the telescopic actuator can be connected by hinges.

[0045] The frame of the water hose truck provided in the present application can drive the frame body to be raised or lowered by the telescopic actuator, the first connecting rod, and the second connecting rod, which is convenient for taking and placing the water hose roll and reduces the use of manpower. The frame can also be folded to reduce space occupancy and facilitate transportation. The structure is reliable and not easy to get stuck.
