Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, specifically to a telescopic slag removal device and inclined shaft construction equipment for inclined shaft construction. Background Technology
[0002] Inclined shafts are inclined adit tunnels excavated during the excavation of hydroelectric power station shafts (ventilation shafts, outlet shafts, drainage shafts, transport shafts), tunnels, and the laying of pressure pipelines. Due to their harsh underground construction environment and significant inclination, the construction of inclined shafts is much more difficult than that of horizontal tunnels. Drilling and blasting methods are commonly used, with the most common method currently being the reverse shaft enlargement method. This method involves drilling a pilot hole from top to bottom, using a reverse drilling rig to enlarge the hole through the pilot hole using a "pull-up, drill-down" approach, and then using pneumatic drills or rock drilling rigs to drill and blast in sections. The inclined shaft opening is equipped with a transfer yard, hoisting facilities, and ventilation, water, and lighting pipelines. Audio-visual communication is used for communication. Avoidance blasting holes are provided at intervals inside the shaft, and there are pedestrian steps and railings on the sides. The working face has waterproofing and drainage measures. After blasting, the debris is shoveled into the pilot tunnel.
[0003] The construction environment for inclined shafts is harsh, especially for projects with a large inclination. Therefore, developing integrated blasting and excavation trolleys with multi-functional booms to replace manual labor has become a major research direction in inclined shaft construction. However, due to the narrow diameter of the inclined shaft and the correspondingly small size of the trolley, problems such as boom interference and boom efficiency inevitably arise when multiple booms operate sequentially.

[0031] The embodiments of the present invention are described below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention. However, the listed embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments can be combined with each other, wherein the same components are indicated by the same reference numerals.
[0032] Example
[0033] like Figures 1-6 As shown, this embodiment provides a telescopic muck-removing device for inclined shaft construction, including a telescopic cylinder 1 and a muck-removing structure.
[0034] The telescopic cylinder 1 includes an outer cylinder 11, an inner cylinder 12, and a telescopic cylinder 13. The outer cylinder 11 is fixed inside the work trolley 6. The rear end of the inner cylinder 12 is slidably disposed inside the outer cylinder 11. The front end of the inner cylinder 12 extends out of the outer cylinder 11 and is detachably connected to the slag removal structure. The telescopic cylinder 13 is disposed between the inner cylinder 12 and the outer cylinder 11 and is used to drive the inner cylinder 12 to extend out of the outer cylinder 11 or to drive the inner cylinder 12 to retract into the outer cylinder 11.
[0035] Therefore, this utility model utilizes the space of the work trolley to set up a telescopic cylinder 1 fixed inside the work trolley 6. When the slag removal device is in operation, the inner cylinder 12 of the telescopic cylinder 1 extends out of the outer cylinder 11, that is, out of the work trolley 6, so as to drive the slag removal structure connected to the inner cylinder 12 to reach the slag pile for slag removal operation. After the slag removal operation is completed, the inner cylinder 12 of the telescopic cylinder 1 retracts into the work trolley, so as to drive the slag removal structure to be arranged close to the work trolley 6. Thus, the working range and degree of freedom of the rock drilling arm, spraying structure, high-altitude operation device, etc. on the work trolley are greatly improved, solving the problem of slag removal arm interference when multi-arm operation, and greatly improving the working efficiency of the multi-functional work trolley.
[0036] Specifically, the telescopic cylinder 13 is fitted inside the inner cylinder 12, with its rear end extending out of the inner cylinder 12 and fixedly connected to the inner wall of the outer cylinder 11, and its front end fixedly connected to the inner cylinder 12.
[0037] In this embodiment, an inner cylinder nylon slider 14 is provided on the outer surface of the rear end of the inner cylinder 12, and the inner cylinder nylon slider 14 is slidably connected to the inner side wall of the outer cylinder 11.
[0038] In this embodiment, the inner surface of the front end of the outer cylinder 11 is provided with an outer cylinder nylon slider 15, which is slidably connected to the outer side wall of the inner cylinder 12.
[0039] By installing nylon sliders at both the front and rear ends of the telescopic cylinder 1, sufficient inertia is ensured during the operation of the slag removal device to prevent the entire device from shaking, thus solving the problem of excessive vibration in the cantilever slag removal device.
[0040] In addition, both the inner cylinder 12 and the outer cylinder 11 are box-shaped structures, which ensures the rigidity during the slag removal operation and further solves the problem of large vibration of the cantilever slag removal device.
[0041] In this embodiment, the slag removal structure includes a slag removal arm 3, a slag removal bucket 4, and a rotary drive structure 2. One end of the rotary drive structure 2 is fixedly connected to the front end of the inner cylinder 12, and the other end is hinged to the slag removal arm 3 for driving the slag removal arm 3 to rotate. The slag removal bucket 4 is hinged to the front end of the slag removal arm 3, and the slag removal arm 3 is used to drive the slag removal bucket 4 to pitch.
[0042] In this embodiment, the rotary drive structure 2 includes a horizontal rotary drive mechanism 21, a conversion elbow 22, and a vertical rotary drive mechanism 23. The fixed part of the horizontal rotary drive mechanism 21 is fixedly connected to the inner cylinder 12, and its rotating part is connected to the vertical section of the conversion elbow 22. The fixed part of the vertical rotary drive mechanism 23 is connected to the horizontal section of the conversion elbow 22, and its rotating part is hinged to the slag removal arm 3. The vertical rotary drive mechanism 23 is used to drive the slag removal arm 3 to rotate in the vertical plane, and the horizontal rotary drive mechanism 21 is used to drive the slag removal arm 3 to rotate in the horizontal plane.
[0043] The vertical arrangement of the axes of the two rotary drive lasers gives the slag removal boom two degrees of rotation in the vertical direction, making the slag removal boom more flexible and able to reach dead points that cannot be reached by fixed slag removal devices.
[0044] In summary, by incorporating a telescopic cylinder and two mutually perpendicular rotary drives, this device allows the muck-removing device to extend itself to achieve a larger working range when the integrated blasting and excavation trolley is fixed. Furthermore, the two mutually perpendicular rotary drive mechanisms connected to the muck-removing boom ensure greater freedom and a wider working range for the muck-removing device, thereby improving muck-removing efficiency.
[0045] In this embodiment, the slag-removing boom 3 includes a curved arm 31, a connecting arm 32, a first drive cylinder 33, a second drive cylinder 34, and a third drive cylinder 35. The opening of the curved arm 31 faces downward, and its rear end is hinged to the upper part of the fixed part of the vertical rotation drive mechanism 23. Its front end is hinged to the lower part of the rear end of the connecting arm 32, and the front end of the connecting arm 32 is hinged to the slag-removing bucket 4. The first drive cylinder 33 is hinged between the lower part of the fixed part of the vertical rotation drive mechanism 23 and the inner wall of the curved part of the curved arm 31. The second drive cylinder 34 is hinged between the outer wall of the curved part of the curved arm 31 and the upper part of the rear end of the connecting arm 32. The third drive cylinder 35 is hinged between the upper end of the connecting arm 32 and the slag-removing bucket 4.
[0046] Each drive cylinder provides the scooping force, driving the bending arm and connecting arm to work together to enable the scoop bucket 4 to complete the scooping operation. The inner cylinder equipped with the scooping structure extends and retracts within the outer cylinder via nylon sliders, allowing it to be adjusted to any position within the integrated blasting and excavation trolley according to the scooping position. Furthermore, by adjusting the two mutually perpendicularly arranged rotary drives, as well as the coordinated movement of the bending arm and connecting arm, the scoop bucket 4 can be adjusted to any scooping position.
[0047] In this embodiment, the rear end of the slag hopper 4 is provided with a parallelogram-like connecting rod structure 5. The parallelogram-like connecting rod structure 5 includes a front arm 51, an upper arm 52, a rear arm 53, and a lower arm 54. The front arm 51, upper arm 52, rear arm 53, and lower arm 54 are connected end to end by hinge. The upper end of the front arm 51 is hinged to the slag hopper 4, and the lower end of the front arm 51 is hinged to the front end of the slag hopper 4 and the connecting arm 32, respectively. The upper end of the rear arm 53 is hinged to the third drive cylinder 35, and the lower end of the rear arm 53 is hinged to the front end of the connecting arm 32.
[0048] The parallelogram-like linkage structure 5 allows the slag bucket 4 to have greater pitch flexibility, which is beneficial for slag removal operations.

[0050] The inclined shaft construction equipment of this embodiment includes a work trolley 6 and a telescopic muck removal device of embodiment 1. The outer cylinder 11 of the telescopic muck removal device is fixed inside the work trolley 6.
[0051] In this embodiment, the bottom frame of the work trolley 6 is provided with a accommodating space 61, which is located in the middle of the bottom frame along the left and right direction of the work trolley 6, and the outer cylinder 11 is fixed in the accommodating space 61.
[0052] Therefore, rock drilling devices can be arranged at both ends of the work trolley in the left and right directions. When the slag removal device retracts, it will not interfere with the rock drilling operation of the rock drilling device.
