Description

Technical Field

[0001] This invention belongs to the field of highway slope protection frame construction technology, specifically relating to a variable amplitude telescopic mobile working device for slope protection frame construction. Background Technology

[0002] Slope protection frames are a crucial component for ensuring the normal functioning of highways, effectively preventing soil erosion and maintaining slope stability. With the increasing demands for construction efficiency and quality in modern highway construction, the construction quality and efficiency of slope protection frames are receiving growing attention. Currently, slope protection frame construction primarily relies on excavators for trench excavation. However, excavators, as general-purpose equipment, face numerous challenges in situations requiring parallel movement along the slope surface, such as slope protection frame construction. The excavator's working device is articulated, and its movement depends on hydraulic cylinders driving the rotation of various components. During slope protection frame construction, due to the structural limitations of the working device, it cannot maintain relative parallelism with the slope surface during amplitude variation, movement, and extension, making it difficult for the end effector to effectively process specific frame shapes. Furthermore, when the slope is a long slope or has a large angle of inclination, the excavator's working device has a limited working range, insufficient overall flexibility, and difficulty in guaranteeing processing accuracy. Therefore, there is an urgent need to design a variable amplitude, extendable, and mobile working device for slope protection frame construction to improve the efficiency and quality of highway slope protection frame construction.

The variable-amplitude basic boom inner sleeve 3 is installed inside the variable-amplitude basic boom outer sleeve 1, and the telescopic hydraulic cylinder 2 is arranged inside the variable-amplitude basic boom outer sleeve 1 and the variable-amplitude basic boom inner sleeve 3. The variable-amplitude basic boom outer sleeve 1 and the variable-amplitude basic boom inner sleeve 3 are connected by the telescopic hydraulic cylinder 2 to form a telescopic support structure; the first-stage variable-amplitude cylinder 8 is arranged on both sides of the variable-amplitude basic boom outer sleeve 1.

[0035] like Figure 2 As shown, the luffing basic boom outer sleeve 1 adopts a rectangular hollow structure. Inside the luffing basic boom outer sleeve 1, there is a hydraulic cylinder mounting seat 11, which is used to fix the cylinder body of the telescopic hydraulic cylinder 2. On the outer sides of the luffing basic boom outer sleeve 1, there are hydraulic cylinder mounting seats 12, which are used to fix the rod body of the first-stage luffing cylinder 8.

[0036] like Figure 3 As shown, the first-stage luffing cylinder 8 is connected to the outer sleeve 1 of the luffing basic arm, and the rod end of the first-stage luffing cylinder 8 is hinged to the hydraulic cylinder mounting base 12 via a pin.

[0037] like Figure 4 As shown, the inner sleeve 3 of the luffing boom also adopts a rectangular hollow structure. The inner sleeve 3 of the luffing boom is equipped with a hydraulic cylinder mounting seat 31 for connecting the rod of the telescopic hydraulic cylinder 2.

[0039] In this invention, the telescopic hydraulic cylinder 2 is connected to the luffing basic boom outer sleeve 1 and the luffing basic boom inner sleeve 3 respectively. When the telescopic hydraulic cylinder 2 is started, it drives the luffing basic boom inner sleeve 3 to move inside the luffing basic boom outer sleeve 1, thereby realizing length adjustment. The luffing basic boom outer sleeve 1 is equipped with a first-stage luffing cylinder 8. Through the extension and retraction of the first-stage luffing cylinder 8, the rotation and adjustment of the entire working device can be driven.

[0040] This invention allows for the rapid adjustment of the length and amplitude of the inner sleeve 3 of the luffing boom, thereby enabling the rapid adjustment of the overall working range of the working device according to different construction environments. This avoids the need to replace equipment or make complex modifications, thus significantly improving construction efficiency.

[0047] In this invention, the main boom tilting cylinder 7 is connected to the luffing base boom inner sleeve 3 and the main boom support sleeve 4 respectively. When the main boom tilting cylinder 7 is started, it drives the main boom support sleeve 4 to rotate around the luffing base boom inner sleeve 3, thereby realizing the luffing adjustment of the main boom support sleeve 4. The hydraulic motor 5 is installed on the main boom support sleeve 4 and connected to the main boom telescopic arm 6. Starting the hydraulic motor 5 can drive the movement and adjustment of the main boom telescopic arm.

[0048] Through this invention, the variation range of the main boom support sleeve 4 can be adjusted, enabling variable-amplitude rotation of the main boom support sleeve 4. This allows the main boom support sleeve 4 to be parallel to the slope, meeting the construction requirements of different inclination angles on highway slopes, thereby significantly improving the adaptability of the working device and the flexibility of construction. At the same time, the main telescopic boom 6 is driven by the meshing of gears and racks on the hydraulic motor 5, enabling the telescopic movement adjustment of the main boom telescopic boom 6. This can meet the construction requirements of long highway slopes, achieve precise positioning of the end effector, ensure processing accuracy, and improve construction quality.
