Description

Technical Field

[0001] This utility model relates to the field of muck removal arm technology, and in particular to a large-angle inclined shaft muck removal arm. Background Technology

[0002] A high-angle inclined shaft is an underground passage that is inclined at a large angle to the horizontal plane, typically between 45° and 90°. Inclined shafts with an inclination angle greater than 60° are generally referred to as high-angle inclined shafts. They are used to connect tunnels or chambers at different levels to facilitate the transportation of personnel, equipment, and materials, as well as ventilation and drainage. After excavation and blasting of a high-angle inclined shaft, a large amount of rubble is generated and needs to be cleared.

[0003] In existing technologies, most large-angle inclined shaft excavation and blasting debris removal involves excavators and manual labor. Large-angle inclined shafts have a large inclination angle and relatively narrow internal space, making it difficult for excavators to reach the debris during operation. This results in a small working range for excavators, while manual cleaning is inefficient and labor-intensive, leading to a reduced debris removal rate. Therefore, to address these shortcomings, a large-angle inclined shaft debris removal arm is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a large-angle inclined shaft slag removal arm, which aims to improve the problem that in the prior art, some large-angle inclined shafts require both excavators and manual labor to clean up the debris after blasting. However, the excavator has a small working range and the manual cleaning efficiency is low, resulting in a reduction in the speed of debris removal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The large-angle inclined shaft slag removal arm includes a main boom section. A telescopic hydraulic cylinder is fixedly connected to the bottom end of the main boom section. A boom extension section is slidably connected to the inner wall of the main boom section. A slewing mechanism is fixedly connected to the end of the boom extension section away from the main boom section. A boom seat is fixedly connected to the inner wall of the end of the slewing mechanism away from the main boom section. A boom hydraulic cylinder is rotatably connected to the end of the boom seat away from the main boom section. A boom is rotatably connected to the bottom end of the boom seat. A round rod hydraulic cylinder is rotatably connected to the bottom end of the boom. A stick is rotatably connected to the drive end of the round rod hydraulic cylinder. A drive assembly for driving the rotation of subsequent components is rotatably connected to the left end of the stick. A bucket is rotatably connected to the top end of the drive assembly.

[0007] As a further description of the above technical solution:

[0008] The drive assembly includes a support hydraulic cylinder, the bottom end of which is rotatably connected to the left end of the stick, and the drive end of which is rotatably connected to two connecting rods.

[0009] As a further description of the above technical solution:

[0010] The left ends of the two connecting rods are rotatably connected to the bottom left end of the bucket, and the drive end of the supporting hydraulic cylinder is rotatably connected to the bottom left end of the bucket.

[0011] As a further description of the above technical solution:

[0012] The right ends of the two connecting rods are rotatably connected to the front and rear ends of the top of the boom, respectively, and the end of the boom away from the main boom section is rotatably connected to the end of the boom near the main boom section.

[0013] As a further description of the above technical solution:

[0014] The drive end of the boom hydraulic cylinder is rotatably connected to the top of the boom, and the drive end of the telescopic hydraulic cylinder is rotatably connected to the bottom of the telescopic section of the boom near the bottom of the main boom section.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the extension and retraction of the boom telescopic section drives the support hydraulic cylinder to extend and retract. The support hydraulic cylinder pushes two connecting rods, which in turn cause the bucket to rotate around the support hydraulic cylinder, enabling the bucket to open and close. When the bucket approaches the slag pile, it is controlled to close, grabbing gravel and other debris. The bucket can rotate 180 degrees, covering the entire area of ​​the large-angle inclined shaft gravel. The operation is simple, greatly reducing the intensity of manual labor and improving work efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 2 This utility model provides an embodiment of a large-angle inclined shaft muck-removing arm, including a basic boom section 1, which serves as the foundation structure of the entire muck-removing arm, supporting and connecting other components. A telescopic hydraulic cylinder 12 is fixedly connected to the bottom end of the basic boom section 1, and a boom extension section 2 is slidably connected to the inner wall of the basic boom section 1, allowing for flexible adjustment of the muck-removing arm's operating radius to better adapt to the muck-removing needs at different locations within the large-angle inclined shaft. The drive end of the telescopic hydraulic cylinder 12 is rotatably connected to the bottom end of the boom extension section 2 near the basic boom section 1, enabling the telescopic hydraulic cylinder 12 to rotate around the basic boom section 1 when driving subsequent components. A rotary mechanism 3 is fixedly connected to the end of the boom extension section 2 away from the basic boom section 1, allowing for flexible rotation within a certain angle range, thereby changing the direction of other connected components. This allows the working components of the muck-removing arm, such as the bucket 7, to accurately align with muck piles at different locations within the large-angle inclined shaft, greatly improving the flexibility and accuracy of muck-removing operations.

[0023] A boom base 4 is fixedly connected to the inner wall of the end of the slewing mechanism 3 furthest from the main boom section 1. The boom base 4 can rotate + / - 180 degrees relative to the telescopic boom section 2. This provides a mounting base for subsequent connections, ensuring that these components can work stably and coordinately to complete various action combinations of the slag-removing boom. A boom hydraulic cylinder 5 is rotatably connected to the end of the boom base 4 furthest from the main boom section 1. The boom hydraulic cylinder 5 provides partial power to the slag-removing boom, driving the subsequent components to move. Rotation allows for better conversion of its telescopic power into corresponding rotation or oscillation. The bottom end of the boom base 4 is rotatably connected to the boom 11, providing support for its rotation and ensuring stable rotation. The drive end of the boom hydraulic cylinder 5 is rotatably connected to the top end of the boom 11. By driving the boom hydraulic cylinder 5, it can push the boom 11 to rotate around the boom base 4, enabling adjustment of the angle of the subsequent components. A round rod hydraulic cylinder 10 is rotatably connected to the bottom end of the boom 11. The boom 11 converts the driving force of the round rod hydraulic cylinder 10 into a rotational force, causing the boom to rotate around the left end of the boom 11, while simultaneously transmitting the rotational force to subsequent components. The round rod hydraulic cylinder 10 can provide corresponding power support to subsequent components through its own extension and retraction movements.

[0024] The drive end of the round rod hydraulic cylinder 10 is rotatably connected to the stick 9, which drives the round rod hydraulic cylinder 10 to rotate the stick 9. The end of the boom 11 furthest from the main boom section 1 is rotatably connected to the end of the stick 9 closest to the main boom section 1, allowing the stick 9 to rotate around the left end of the boom 11. The left end of the stick 9 is rotatably connected to a drive assembly that drives subsequent components. The drive assembly includes a support hydraulic cylinder 8, the bottom end of which is rotatably connected to the left end of the stick 9. By restricting its rotation, the support hydraulic cylinder 8 can rotate itself, allowing for angle adjustment as needed. The drive end of the support hydraulic cylinder 8 is rotatably connected to two connecting rods 6, which drive the support hydraulic cylinder 8 to rotate. The top of the drive assembly is rotatably connected to a bucket 7 for clearing gravel. The right ends of the two connecting rods 6 are rotatably connected to the front and rear ends of the top of the stick 9, respectively, to restrict the rotation of the connecting rods 6, allowing the connecting rods 6 to drive the bucket 7 to rotate. The left ends of the two connecting rods 6 are rotatably connected to the bottom left end of the bucket 7, and the drive end of the supporting hydraulic cylinder 8 is rotatably connected to the bottom left end of the bucket 7. By driving the supporting hydraulic cylinder 8, the bucket 7 is pushed to drive the connecting rods 6 to rotate around the top of the supporting hydraulic cylinder 8, so that it can adapt to the crushed stone at different angles.

[0025] Working principle: The telescopic hydraulic cylinder 12 is operated to extend and retract as needed, pushing the telescopic boom section 2 to slide within the main boom section 1, adjusting the boom to a suitable length to cover the approximate area of ​​the slag pile to be cleared. Then, the slewing mechanism 3 is activated, causing the boom base 4 to rotate. The arm hydraulic cylinder 5 is then controlled to extend and retract, pushing the boom 11 to rotate around the boom base 4, adjusting the angle of the boom 11, and consequently changing the angle and posture of subsequent components, preparing the bucket 7 to approach the slag pile at a suitable angle. Next, the round rod hydraulic cylinder 10 is operated to extend and retract, driving the stick 9 to rotate around the left end of the boom 11, further fine-tuning the position and angle of the bucket 7 to better fit the actual situation of the slag pile, facilitating the subsequent slag removal operation.

[0026] At this time, the drive support hydraulic cylinder 8 performs a telescopic action. The support hydraulic cylinder 8 pushes two connecting rods 6, and the connecting rods 6 drive the bucket 7 to rotate around the support hydraulic cylinder 8, so that the bucket 7 can open and close. When the bucket 7 approaches the slag pile, control the bucket 7 to close and grab gravel and other debris.

[0027] After the bucket 7 has grabbed enough crushed stone, the actions of each hydraulic cylinder are adjusted in the reverse order of the above steps (such as first adjusting the angle of the bucket 7, and then adjusting the angle and position of the boom 11 and the slewing mechanism 3, etc.) to move the bucket 7 to a suitable unloading position. Then, the support hydraulic cylinder 8 is controlled again to open the bucket 7 and unload the grabbed crushed stone, completing one slag removal cycle.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
