For example, an aerial work vehicle includes a telescopic arm device, a hanging basket and a pipeline device, wherein the hanging basket is connected to the last telescopic arm of the telescopic arm device, and a hydraulic cylinder is also arranged between the hanging basket and the telescopic arm device. The hydraulic cylinder can keep the hanging basket in a suitable posture at all times by adjusting the telescopic length of its piston rod. In addition, the hanging basket is also provided with lighting lamps, weighing sensors and other devices. The pipeline device in the telescopic arm device of the aerial work vehicle includes hydraulic pipelines, power lines connected to lighting lamps and signal lines connected to weighing sensors. As the telescopic time of the telescopic arm device increases, the pipeline device will be elastically stretched, resulting in a problem of looseness.

[0037] In view of this, the embodiment of the utility model provides a pipeline adjustment device for adjusting the tightness of the pipeline device inside the telescopic arm device of the working machine. Figure 1 and Figure 2 As shown, the pipeline adjustment device provided in this embodiment includes a mounting seat 11, a supporting wheel 12 and an adjustment assembly 13. The mounting seat 11 is used to be mounted on the telescopic arm device. In some embodiments, the mounting seat 11 can be a plate-like structure or a block-like structure, and is connected to the telescopic arm device by bolts, pins, welding, etc.

[0038] The supporting wheel 12 is installed on the mounting seat 11, and the supporting wheel 12 is used to support the pipeline, that is, the pipeline passes around the outer circumference of the supporting wheel 12 and is supported by the outer circumference of the supporting wheel 12. The adjustment component 13 is arranged between the mounting seat 11 and the supporting wheel 12, and is suitable for adjusting the distance between the supporting wheel 12 and the mounting seat 11.

[0039] The mounting seat 11 is used to be installed on the telescopic arm, and the supporting wheel 12 is set on the mounting seat 11 through the adjustment component 13. The supporting wheel 12 is used to support the pipeline, that is, the pipeline in the telescopic arm passes around the outer peripheral surface of the supporting wheel 12 and is supported by the supporting wheel 12. The adjustment component 13 is used to adjust the distance between the supporting wheel 12 and the mounting seat 11, and then the tightness of the pipeline can be adjusted. When the pipeline becomes loose as the telescopic arm is extended and retracted, the distance between the supporting wheel 12 and the mounting seat 11 can be increased by adjusting the component 13, so as to tighten the pipeline and avoid the problem of pipeline de-slotting, wear or breakage.

[0040] In some embodiments, the adjustment assembly 13 may include a screw rod 131, a first nut 133, a second nut 134, and a bearing plate 132, wherein one end of the screw rod 131 is fixedly connected to the mounting base 11, and may be connected to the mounting base 11 by welding. The first nut 133 and the second nut 134 are both assembled on the screw rod 131, and the positions of the first nut 133 and the second nut 134 on the screw rod 131 may be adjusted by rotating the first nut 133 and the second nut 134.

[0041] The bearing plate 132 includes a roller mounting portion and a screw connecting portion, which are connected to each other. The roller mounting portion and the screw connecting portion belong to different parts of the bearing plate 132. The roller mounting portion is used to mount the roller 12. Specifically, the roller 12 can be connected to the roller mounting portion by connecting members such as bolts and pins, and the screw connecting portion is used to connect to the screw 131. Specifically, the screw connecting portion is provided with a through hole, the diameter of which is slightly larger than the diameter of the screw 131. The screw connecting portion is sleeved on the outer periphery of the screw 131 through the through hole. At the same time, the first nut 133 and the second nut 134 are respectively arranged on both sides of the screw connecting portion, that is, the screw connecting portion is sandwiched between the first nut 133 and the second nut 134.

[0042] In this embodiment, the screw rod 131 is fixed on the mounting seat 11, and the screw rod connection part of the bearing plate 132 is connected to the screw rod 131. Specifically, two nuts are provided on the screw rod 131, namely, a first nut 133 and a second nut 134, wherein the first nut 133 is relatively close to the mounting seat 11, and the second nut 134 is relatively far away from the mounting seat 11, and the bearing plate 132 is clamped between the first nut 133 and the second nut 134. The supporting wheel 12 is mounted on the supporting wheel mounting part of the bearing plate 132, and the distance between the supporting wheel 12 and the mounting seat 11 can be adjusted by adjusting the axial position of the bearing plate 132 on the screw rod 131. When adjustment is required, the first nut 133 can be rotated first to make the first nut 133 move along the screw rod 131, and then the second nut 134 can be adjusted so that the bearing plate 132 is clamped between the first nut 133 and the second nut 134.

[0043] In a further embodiment, at least two screw rods 131 are provided, and each screw rod 131 is provided with a first nut 133 and a second nut 134; at least two screw rod connecting parts are provided and are connected to the screw rods 131 one by one. For example, two screw rods 131 may be provided, and the bearing plate 132 is provided with two screw rod connecting parts. Specifically, the two screw rod connecting parts are respectively provided at the two side positions of the bearing plate 132, and the middle position of the bearing plate 132 is the connecting part of the supporting wheel 12. The first nut 133 and the second nut 134 are provided on the two screw rods 131, and the screw rod connecting parts on both sides of the bearing plate 132 are respectively sleeved on the two screw rods 131 and clamped by the first nut 133 and the second nut 134 on the corresponding screw rod 131. When it is necessary to adjust the distance between the supporting wheel 12 and the mounting seat 11, it is necessary to adjust the nuts on the two screw rods 131 respectively.

[0044] With such configuration, the support plate 132 has a plurality of screw connection parts, each of which is connected to the screw 131 , and the support plate 132 is supported by the plurality of screws 131 , thereby making the supporting wheel 12 more stable.

Specifically, the baffle structure 124 can be a circular plate, whose diameter is larger than the diameter of the supporting wheel 12, and the baffle structure 124 is concentrically arranged with the supporting wheel 12. In this way, the baffle structures 124 on both axial sides of the supporting wheel 12 can effectively constrain the pipeline, avoiding the problem of the pipeline falling off the outer peripheral surface of the supporting wheel 12.

[0046] In an optional embodiment, the supporting wheel 12 is configured as a half wheel structure. Specifically, the half wheel structure can be a half wheel structure cut along any diameter direction of the circular wheel structure. The half wheel structure is provided with a clamping groove 123, which can be provided on the section in the above diameter direction, and the clamping groove 123 can be clamped with the supporting wheel mounting portion of the bearing plate 132.

[0047] In some embodiments, the slot 123 is configured as a square slot, and the cross-sectional shape of the roller mounting portion is consistent with the shape of the slot 123. Since the cross-sectional shape of the roller mounting portion is consistent with the shape of the slot 123, that is, both are square structures, when the slot 123 is clamped on the roller mounting portion, the relative rotation of the two can be restricted, thereby achieving a better positioning effect.

[0048] In a further embodiment, the thickness of the supporting wheel mounting portion may be greater than the thickness of the screw rod connecting portion. With such an arrangement, the supporting wheel can be better clamped on the supporting wheel mounting portion to ensure the connection stability between the two.

[0049] In a further embodiment, the half wheel structure and the supporting wheel mounting portion are provided with corresponding connecting holes 121, and the half wheel structure and the supporting wheel mounting portion are fixedly connected by a connecting member 122 inserted into the connecting hole 121. The connecting hole 121 can penetrate the half wheel structure and the supporting wheel mounting portion in a radial direction, and the connecting member 122 can specifically be a screw, a pin, etc.

[0050] When installing the half-wheel structure on the supporting wheel mounting portion, the slot 123 of the half-wheel structure can be firstly snap-fitted and positioned on the supporting wheel mounting portion, and then the connecting member 122 can be inserted into the corresponding connecting holes 121 of the two to fix the two together.

[0051] It should be noted that in order to achieve a reliable connection between the support wheel 12 and the supporting plate 132, a plurality of connecting holes 121 may be correspondingly provided on the half-wheel structure and the support wheel mounting portion, and a reliable connection between the half-wheel structure and the support wheel mounting portion is achieved by means of connecting parts 122 inserted into the plurality of connecting holes 121.

The derivation process of this beneficial effect is generally similar to the derivation process of the beneficial effect brought by the above-mentioned pipeline adjustment device, and will not be repeated here.
