Description

Technical Field

[0001] This invention belongs to the field of highway slope protection frame construction technology, specifically relating to a telescopic lifting arm for highway arch slope protection frame construction. Background Technology

[0002] Highway slope protection frame construction is a technically demanding and complex engineering task. With the increasing demands for construction efficiency and quality in modern highway construction, highway arch slope protection frame construction vehicles have emerged. These vehicles are capable of trajectory-based operations in complex terrain environments and are currently one of the key pieces of equipment for highway arch slope protection frame construction. The working device of a highway arch slope protection frame construction vehicle generally includes a basic boom, a main boom, a support boom, and an end-effector. The main boom is kept parallel to the highway slope by adjusting the basic boom, serving as the motion reference for the support boom. The support boom is driven by a hydraulic motor to achieve translational and rotational movements along the main boom, thereby driving the end-effector to complete the construction task of the arch slope protection frame. As one of the core components of the highway arch slope protection frame construction vehicle, the support boom structure needs to be able to quickly adjust its working radius and precisely control the movement trajectory of the end-effector to complete the trajectory-based construction of the arch slope protection frame in complex terrain. However, existing support boom structures still have significant limitations in practical applications. The currently designed outrigger structure is mainly used for constructing single-size frames. When the frame size changes, the working radius of the outrigger cannot be quickly adjusted, requiring equipment replacement or complex modifications, leading to decreased construction efficiency. Furthermore, the existing outrigger structure cannot accurately measure the working radius; the positioning of the working mechanism at the end of the outrigger relies primarily on manual measurement and adjustment. This method is prone to causing the working mechanism to deviate from its preset trajectory in complex construction environments, thus affecting construction quality. In addition, the existing outrigger structure lacks vertical adjustment capability, preventing the working mechanism from fully conforming to the slope surface during construction, similarly impacting construction quality and efficiency.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figures 1-4 As shown, a telescopic lifting boom for the construction of an arched slope protection frame for highways is characterized by comprising: a telescopic boom outer sleeve 1, a telescopic hydraulic cylinder 2, a pull-wire sensor 3, a telescopic boom inner sleeve 4, a lifting slide assembly 55, a lifting hydraulic cylinder 6, and a lifting quick-connect assembly 7. The telescopic boom inner sleeve 4 is installed inside the telescopic boom outer sleeve 1, and the telescopic hydraulic cylinder 2 is arranged inside the telescopic boom outer sleeve 1 and the telescopic boom inner sleeve 4. The telescopic boom outer sleeve 1 and the telescopic boom inner sleeve 4 are connected by the telescopic hydraulic cylinder 2 to form a telescopic support structure; the pull-wire sensor 3 is arranged on the side of the telescopic boom outer sleeve 1.

[0030] like Figure 2As shown, the telescopic boom outer sleeve 1 adopts a rectangular hollow structure. A hydraulic cylinder mounting seat 11 is installed inside the telescopic boom outer sleeve 1, and a friction block 12 is arranged at the inner end of the telescopic boom outer sleeve 1. The hydraulic cylinder mounting seat 11 is used to fix the cylinder body of the telescopic hydraulic cylinder 2, and the friction block 12 can reduce friction during the sliding process. The cable sensor 3 is fixed to the outer end of the telescopic boom outer sleeve 1, and the cable end is fixed to the end panel 41 by a buckle. The telescopic cable sensor 3 is used to measure the telescopic displacement in real time and provide feedback on the working radius.

[0031] like Figure 3 As shown, the inner sleeve 4 of the telescopic boom also adopts a rectangular hollow structure. The inner sleeve 4 of the telescopic boom is equipped with a hydraulic cylinder mounting seat 43. The end panel 41 is welded to the end of the inner sleeve 4 of the telescopic boom for connecting the lifting slide assembly 55. A reinforcing rib 42 is provided between the end panel 41 and the inner sleeve 4 of the telescopic boom to enhance the structural stability.

[0032] like Figure 4 As shown, the telescopic hydraulic cylinder 2 is connected to the telescopic arm outer sleeve 1 and the telescopic arm inner sleeve 4 respectively; the cylinder body end of the telescopic hydraulic cylinder 2 is hinged to the hydraulic cylinder mounting seat 11 by a pin, and the rod body end of the telescopic hydraulic cylinder 2 is hinged to the hydraulic cylinder mounting seat 43 by a pin.

[0033] In this invention, the telescopic hydraulic cylinder 2 is connected to the telescopic boom outer sleeve 1 and the telescopic boom inner sleeve 4 respectively. When the telescopic hydraulic cylinder 2 is activated, it drives the telescopic boom inner sleeve 4 to move within the telescopic boom outer sleeve 1, thereby achieving the function of adjusting the outrigger length to adapt to different working radius requirements. The friction block 12 between the telescopic boom inner and outer sleeves further reduces friction and improves the smoothness of movement.

[0034] To measure the telescopic displacement and provide feedback on the working radius, a wire sensor 3 is mounted on the telescopic boom hydraulic cylinder 2. During the extension and retraction of the inner sleeve 4 of the telescopic boom, the sensor measures the telescopic displacement of the boom in real time and feeds the data back to the control system. The operator adjusts the working radius in real time based on the sensor data, thereby ensuring accurate positioning of the boom under different working conditions.

[0035] This invention allows for precise adjustment of the extension length of the outrigger to adapt to different working radius requirements. Through the measurement and feedback of the pull-wire sensor 3, the device's positioning is ensured to be accurate, thus improving construction efficiency and quality.

[0036] Example 2

[0037] like Figure 1 , Figures 5-7As shown, a telescopic lifting boom for the construction of an arched slope protection frame for highways includes a telescopic boom outer sleeve 1, a telescopic hydraulic cylinder 2, a guy wire sensor 3, a telescopic boom inner sleeve 4, a lifting slide assembly 55, a lifting hydraulic cylinder 6, and a lifting quick-connect assembly 7. The lifting slide assembly 55 includes a fixed plate 51, two U-shaped slides 52, and a hydraulic cylinder mounting base 53. The lifting slide assembly 55 is vertically installed at the end of the telescopic boom inner sleeve 4. The lifting quick-connect assembly 7 includes a side plate 71, a slider 72, and a hydraulic cylinder mounting base 73. The proximal end of the side plate 71 is connected to the slider 72, and the slider 72 forms a sliding connection with the U-shaped slides 52. The lifting quick-connect assembly 7 and the lifting slide assembly 55 are connected and driven by the lifting hydraulic cylinder 6, enabling the lifting quick-connect assembly 7 to be adjusted along the vertical direction of the U-shaped slides 52.

[0038] like Figure 5 As shown, the back of the fixing plate 51 in the lifting slide assembly 55 has a through hole. The fixing plate 51 is fixedly connected to the end panel 41 by bolts. Two U-shaped slides 52 are symmetrically welded to the left and right sides of the front of the fixing plate 51 (51) and are used in conjunction with the slider 72 to ensure the stable movement of the lifting quick-connect assembly 7. The hydraulic cylinder mounting base 3 53 is welded to the upper part of the front of the fixing plate 51.

[0039] like Figure 6 As shown, the side plate 71 of the lifting quick-connect assembly 7 has a pin hole at its near end. The side plate 71 is connected to the slider 72 by a pin shaft. The four sliders 72 are fixed to the ends of the two pin shafts respectively. The sliders 72 are installed in the U-shaped slide rail 52 and can slide in the U-shaped slide rail 52. Ribs 74 are provided between the side plates 71 to enhance the overall structural rigidity. The hydraulic cylinder mounting base 73 is welded to the middle of the two side plates 71. The far end of the side plate 71 has a pin hole for mounting different working mechanisms.

[0040] like Figure 7 As shown, the lifting hydraulic cylinder 6 is connected to the lifting slide assembly 55 and the lifting quick-connect assembly 7 respectively; the cylinder body end of the lifting hydraulic cylinder 6 is hinged to the hydraulic cylinder mounting base 3 53 via a pin, and the rod end of the lifting hydraulic cylinder 6 is hinged to the hydraulic cylinder mounting base 4 73 via a pin. The extension and retraction of the lifting hydraulic cylinder 6 drives the lifting quick-connect assembly 7 to lift and lower, thereby completing the adjustment of the working height of the end working mechanism.

[0041] When the lifting hydraulic cylinder 6 is activated, the lifting quick-connect assembly 7 slides vertically within the U-shaped slide rail 52 under its drive. Through the cooperation of the slider 72 and the U-shaped slide rail 52, a smooth lifting process is achieved, thereby realizing the vertical lifting of the working mechanism and meeting the operational needs of the equipment at different construction heights.

[0042] By adjusting the extension and retraction of the lifting hydraulic cylinder 6, the positioning and height adaptation of the working mechanism can be quickly achieved. This lifting function adds vertical adjustment capability to the outrigger structure, improving work efficiency and quality.
