Description

Technical Field

[0001] This utility model relates to the field of stone-throwing mechanism technology, and in particular to a multi-section telescopic positioning device for inclined chute. Background Technology

[0002] In water conservancy projects and waterway dredging, rock-throwing is a crucial process for ensuring structural stability (such as erosion control of dikes) and improving navigation conditions (such as filling underwater depressions). Currently, commercially available rock-throwing devices have the following main shortcomings: Limited range of extension: Most existing chutes are single or two fixed structures, which cannot flexibly adjust the length according to water depth and stone throwing distance. They are difficult to adapt to the depth and horizontal distance requirements of different operating scenarios. Especially when throwing stones in deep water or over long distances, the problem of stone delivery not being in place is likely to occur.

[0003] Low positioning accuracy: Most devices can only achieve angle adjustment in a single direction (such as the vertical direction), lacking the ability to adjust horizontally and in multiple dimensions, which makes it impossible for the chute to accurately align with the underwater target area, resulting in large deviations in stone throwing and requiring repeated adjustments, thus affecting operational efficiency.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for a catapult device with a large telescoping range, high-precision positioning, stable feeding and low interference risk to meet the operational needs of complex engineering scenarios. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-section telescopic positioning device for inclined chute.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The inclined chute multi-section telescopic positioning device includes a rotary drive base. A rotary chassis is installed at the output end of the rotary drive base. The rotary chassis is connected to an offset arm through an angle adjustment mechanism. Several nested telescopic hollow arms are provided on one side of the offset arm. Adjacent telescopic hollow arms are connected by telescopic rods to adjust their relative lengths. The diameter of the telescopic hollow arms decreases in stages. The telescopic hollow arm with the largest diameter is connected to the offset arm. An angle-adjustable feeding mechanism is provided at the end of the telescopic hollow arm with the largest diameter.

[0007] Preferably, the angle adjustment mechanism includes an arm body one connected to a rotating chassis, an arm body two hinged to the upper end of the arm body one, a telescopic rod one hinged at the angle between the arm body one and the arm body two, and a telescopic rod four hinged at the angle between the arm body two and the offset arm.

[0008] Preferably, the angle-adjustable feeding mechanism includes a curved tube arm connected to a telescopic hollow arm, with symmetrically arranged support arms at the ends of the curved tube arm, a hopper rotatably connected between the support arms, the lower end of the hopper extending into the curved tube arm, and a telescopic rod three hinged between the hopper and the curved tube arm.

[0009] Preferably, the first telescopic rod, the second telescopic rod, the third telescopic rod, and the fourth telescopic rod are one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder.

[0010] Preferably, the vertical plane containing the center of the telescopic hollow arm and the vertical plane containing the center of the second arm body are parallel but not coplanar.

[0011] Compared with the prior art, the beneficial effects of this utility model are: With a wide telescopic range and strong adaptability: Through the combination of multi-section nested telescopic hollow arm and telescopic rod, the length of the chute can be adjusted significantly to adapt to different water depths (from shallow water to deep water) and the needs of horizontal stone throwing distance. It can complete various scenarios without changing equipment. Multi-dimensional positioning with high precision: The rotating drive base achieves 360° horizontal rotation, and the telescopic rods one and four adjust the vertical height and offset angle respectively. The three work together to enable the telescopic hollow arm to accurately align with the designated underwater target area, significantly improving positioning accuracy. Stable feeding and high efficiency: The telescopic rod can adjust the angle of the hopper in real time to ensure that the hopper is always horizontal, avoid stone spillage, and reduce the safety risks of operation. No interference in structure and long service life: The telescopic hollow arm and the vertical plane of the second arm body are parallel and not coplanar, which effectively avoids collision and friction of parts during movement.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-3 The inclined chute multi-section telescopic positioning device includes a rotary drive base 1, a rotary base 2 installed at the output end of the rotary drive base 1, an offset arm 6 connected to the rotary base 2 through an angle adjustment mechanism, a number of nested telescopic hollow arms 7 are provided on one side of the offset arm 6, and adjacent telescopic hollow arms 7 are connected by telescopic rods 8 to adjust their relative lengths. The diameter of the telescopic hollow arms 7 decreases step by step, and the telescopic hollow arm 7 with the largest diameter is connected to the offset arm 6. The end of the telescopic hollow arm 7 with the largest diameter is provided with an angle-adjustable feeding mechanism.

[0017] In this embodiment, the angle adjustment mechanism includes an arm body 3 connected to the rotating chassis 2, an arm body 5 hinged to the upper end of the arm body 3, a telescopic rod 4 hinged at the angle between the arm body 3 and the arm body 5, and a telescopic rod 13 hinged at the angle between the arm body 5 and the offset arm 6.

[0018] In this embodiment, the angle-adjustable feeding mechanism includes a bent tube arm 9 connected to the telescopic hollow arm 7. The end of the bent tube arm 9 is provided with symmetrically arranged support arms 10. A hopper 11 is rotatably connected between the support arms 10. The lower end of the hopper 11 extends into the bent tube arm 9. A telescopic rod 12 is hinged between the hopper 11 and the bent tube arm 9.

[0019] In this implementation scheme, telescopic rod 1 (4), telescopic rod 2 (8), telescopic rod 3 (12), and telescopic rod 4 (13) are one of hydraulic cylinders, pneumatic cylinders, and electric cylinders.

[0020] In this implementation scheme, the vertical plane where the center of the telescopic hollow arm 7 is located is parallel to and not coplanar with the vertical plane where the center of the arm body 5 is located, thus avoiding interference.

[0021] The rotating drive base 1 controls the rotation angle of the rotating chassis 2, the telescopic rod 4 controls the angle between the arm 3 and the arm 5, the telescopic rod 13 controls the angle between the arm 5 and the offset arm 6, and the telescopic rod 8 controls the length of the telescopic hollow arm 7. Through the interaction of the above structures, the telescopic hollow arm 7 is controlled to extend into a designated position below the water surface. Stones enter from the hopper 11 and fall along the middle channel of the telescopic hollow arm 7, which can guide the stones to the designated position and improve the stone throwing progress. During this process, the angle of the hopper 11 can be controlled by the telescopic rod 12 to ensure that the hopper 11 is kept in a horizontal state when the angle of the telescopic hollow arm 7 changes, which is convenient for loading stones.
