AI Technical Summary
The outrigger structure of existing recovery vehicles occupies a large space and is not compact, which cannot meet the chassis height requirements, and the stability is insufficient, especially when clearing obstacles from the side.
It adopts a sliding concealed outrigger structure, including an outer cylinder, an intermediate cylinder, a support cylinder, a tie rod, and a hydraulic cylinder. The hydraulic cylinder drives the sliding and rotation of the intermediate cylinder and the support cylinder to achieve the horizontal concealed extension and retraction of the support cylinder. The front end of the support cylinder contacts the ground to stabilize the vehicle body.
The outriggers feature a compact design, reducing space requirements and improving the stability and ease of use of the side-positioning recovery vehicle.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of road clearing equipment, and in particular to a sliding concealed outrigger and a side-position clearing vehicle equipped with the sliding concealed outrigger. Background Technology
[0002] Road clearing vehicles are essential equipment in modern transportation. To cope with clearing obstacles on complex road surfaces, some existing road clearing vehicles are equipped with side forklift mechanisms on their sides.
[0003] However, when forklifted, the sides of the side-mounted wrecker are subjected to strong gravity, so outriggers are designed at the bottom of the wrecker. Existing outriggers of this type are all driven by hydraulic cylinders and use a vertical lifting mechanism. When the outrigger is retracted, the hydraulic cylinder and the outrigger are at a certain height in the vertical direction. Therefore, this structure places certain requirements on the chassis height of the wrecker. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a sliding concealed outrigger with a compact structure, small footprint, and convenient use, as well as a side-position clearing vehicle equipped with the sliding concealed outrigger.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model provides a sliding concealed outrigger, including an outer cylinder, a middle cylinder, a support cylinder, a pull rod, and a hydraulic cylinder. The outer cylinder has a hollow inner cavity. The middle cylinder is slidably connected to the hollow inner cavity. The hydraulic cylinder is disposed in the hollow inner cavity, with its rear end rotatably connected to the outer cylinder. The telescopic rod at the front end of the hydraulic cylinder is connected to the middle cylinder. The support cylinder is slidably connected to the hollow inner cavity, with one end extending outside the hollow inner cavity. The end of the support cylinder located inside the hollow inner cavity is rotatably connected to the middle cylinder. The pull rod is a set, with one end slidably connected along the outer cylinder and the other end rotatably connected to the support cylinder. The hydraulic cylinder can drive the middle cylinder to slide along the hollow inner cavity of the outer cylinder, and the middle cylinder can drive the support cylinder to extend out of or retract into the hollow inner cavity.
[0007] To facilitate the operation of the hydraulic cylinder, a first pin is fixed to the rear end of the outer cylinder, and the rear end of the hydraulic cylinder is rotatably connected to the first pin.
[0008] Correspondingly, a second pin is fixed inside the intermediate cylinder, and the telescopic rod at the front end of the oil cylinder is rotatably connected to the second pin.
[0009] To facilitate the extension and retraction of the intermediate cylinder, and to simultaneously enable the extension, retraction, and rotation of the support cylinder, a third pin is fixed at one end of the intermediate cylinder near the support cylinder, and the rear end of the support cylinder is rotatably connected to the third pin.
[0010] In order to guide the extension, retraction and rotation of the support cylinder, the bottom end of the outer cylinder is provided with sliding grooves parallel to the horizontal plane on both sides. A fourth pin is slidably connected in the sliding groove, and the rear ends of the two pull rods are rotatably connected to the two ends of the fourth pin respectively.
[0011] Furthermore, a fifth pin is fixed to one end of the support cylinder extending outside the hollow inner cavity, and the front ends of the two pull rods are rotatably connected to the fifth pin.
[0012] To further enable the support cylinder to rotate downwards, the front end of the outer cylinder has a downwardly extending arc-shaped guide portion, along which the support cylinder can slide.
[0013] In order to ensure that the support cylinder can make effective contact with the ground, a support plate is rotatably connected to the front end of the support cylinder.
[0014] This utility model also provides a side-positioning tow truck, which is equipped with at least one set of the above-mentioned sliding concealed outriggers.
[0015] The beneficial effects of this utility model are: by installing sliding concealed outriggers on the side-positioning recovery vehicle, this utility model can stabilize the vehicle body when operating a side-positioning forklift. The sliding concealed outriggers are horizontally installed on the side-positioning recovery vehicle and can achieve horizontal concealed extension and retraction. They have a compact structure, occupy little space, and are relatively convenient to install and use. Attached Figure Description

[0021] Example 1:
[0022] like Figure 1-3 The sliding concealed outrigger shown includes an outer cylinder 1, an intermediate cylinder 2, a support cylinder 3, a pull rod 6, and a hydraulic cylinder 4. The outer cylinder 1 is a rectangular square tube with a hollow inner cavity. The intermediate cylinder 2 is a rectangular square tube slidably connected to the hollow inner cavity. The hydraulic cylinder 4 is disposed within the hollow inner cavity. The rear end of the hydraulic cylinder 4 is rotatably connected to a first pin 9 inside the outer cylinder 1. The telescopic rod at the front end of the hydraulic cylinder 4 extends into the intermediate cylinder 2 and is rotatably connected to a second pin 10 inside the intermediate cylinder 2. The support cylinder 3 is also a rectangular square tube, slidably connected to the hollow inner cavity, with one end (front end) of the support cylinder 3 extending outside the hollow inner cavity. The rear end of the support cylinder 3 located within the hollow inner cavity... The outer cylinder 1 has a downward-extending arc-shaped guide 7 at its front end, and the support cylinder 3 can slide along the arc-shaped guide 7. The support cylinder 3 has a support plate 5 rotatably connected to its front end. The pull rods 6 are a set, and the pull rods 6 are strip-shaped structures. One end (rear end) of the pull rod 6 is slidably connected along the bottom of the outer cylinder 8. The bottom end of the outer cylinder 1 has grooves 8 parallel to the horizontal plane on both sides. The fourth pin 12 is slidably connected in the grooves 8. The rear ends of the two pull rods 6 are rotatably connected to the two ends of the fourth pin 12, respectively. The other end (front end) of the pull rod 6 is rotatably connected to the fifth pin 13 on the support cylinder 3.
[0023] Before use, the intermediate cylinder 2 and the support cylinder 3 are both concealed within the hollow inner cavity of the outer cylinder 1, as shown in the image. Figure 1 As shown, during use, the telescopic rod of the hydraulic cylinder 4 extends, pushing the intermediate cylinder 2 to slide forward. The intermediate cylinder 2 then pushes the support cylinder 3 to slide forward gradually. The pull rod 6 is pulled to slide forward along the slide groove 8. When the rear end of the pull rod 6 slides to the end of the slide groove 8, the telescopic rod of the hydraulic cylinder 4 continues to extend, and the support cylinder 3 is pulled downward by the pull rod 6. Under the action of the arc-shaped guide part 7, the support cylinder 3 gradually rotates, and finally the support plate 5 contacts the ground, realizing lateral support.
[0024] Example 2:
[0025] like Figure 4As shown, this embodiment provides a side-positioning recovery vehicle. The side-positioning recovery vehicle 14 is equipped with at least one set of the above-mentioned sliding concealed outriggers 15, which can be located at the rear of the side-positioning recovery vehicle 14.
