[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figure 1 , which is a schematic structural diagram of the slag scraper arm provided by the present invention. The slag scraper arm 50 includes a large telescopic arm assembly 51, a small telescopic arm assembly 53, a rotating platform 57, and a bucket 59. The rotating platform 57 includes a platform base 571, a platform base luffing cylinder 573, a slewing mechanism 575, and a turntable base 577. The two ends of the platform base luffing cylinder 573 are respectively connected to the large telescopic arm assembly 51 and the platform base 571. The slewing mechanism 575 is integrally installed with the platform base 571. The turntable base 577 is fixedly installed at the bottom of the slewing mechanism 575. One end of the small telescopic arm assembly 53 is connected to the turntable base 577 and can rotate 360 ​​degrees with the slewing mechanism 575. The other end of the small telescopic arm assembly 53 is connected to the bucket 59. The rotation of the rotating platform 57 can drive the small telescopic arm assembly 53 to rotate 360° around the connection. Specifically, the slewing mechanism rotates 360°, driving the small telescopic arm assembly connected thereto to rotate 360°, thereby realizing 360° free slag removal by the slag scraping arm. At the same time, the platform seat variable amplitude cylinder 573 is actuated to control the pitch angle of the small telescopic arm assembly 53, thereby expanding the operating range of the bucket 59. During the operation, slag scraping operations can be carried out over a large range without moving the work trolley, which greatly improves work efficiency.

[0023] Specifically, in this embodiment, the telescopic boom assembly 51 includes a telescopic boom 511, a telescopic boom cylinder 513, and an adapter frame 515. One end of the telescopic boom cylinder 513 is hinged to one end of the telescopic boom 511 via an intermediate piece 517, and the other end is hinged to the other end of the telescopic boom 511. The adapter frame 515 is mounted on the end of the telescopic boom 511, and the platform base 571 is hinged to the other end of the adapter frame 515. The two ends of the platform base boom cylinder 573 are hinged to the adapter frame 515 and the platform base 571, respectively. The telescopic boom cylinder 513 controls the pitch angle of the telescopic boom, thereby controlling the pitch angle of the boom. The adapter frame 515 primarily serves as a connector to enhance structural stability.

[0024] Specifically, the large telescopic arm 511 includes a plurality of retractable large arms, each of which has a different inner diameter. The plurality of retractable large arms are sequentially arranged in one body to achieve length changes, thereby flexibly changing the length of the large telescopic arm. This retractable structure is an existing conventional technology and will not be described in detail in this embodiment.

[0025] Specifically, in this embodiment, the small telescopic arm assembly 53 includes a small telescopic arm 531 and a small telescopic arm luffing cylinder 533. The two ends of the small telescopic arm are respectively hinged to the turntable 577 and the bucket 59. One end of the small telescopic arm luffing cylinder 533 is hinged to the turntable 577, and the other end is hinged to the small telescopic arm 531. The bucket 59 is driven by the bucket cylinder 591 to rotate at a certain angle, thereby achieving flexible rotation of the bucket 59.

[0026] Specifically, the small telescopic arm 531 includes a multi-section telescopic small arm frame, and the inner diameters of the multi-section small arm frame are different. The multi-section telescopic small arm frame is integrated into one body to achieve length changes, thereby flexibly changing the length of the small telescopic arm. This telescopic structure is an existing known technology and will not be repeated in this embodiment.

[0027] Specifically, the slewing mechanism 575 includes a slewing bearing and a slewing drive connected to the slewing bearing for driving the slewing bearing to rotate. The slewing drive drives the slewing bearing to move, and in turn drives the platform seat 571 mounted on the slewing bearing to rotate, thereby achieving different angles of rotation of the scraper arm.

[0028] Furthermore, the rotary drive includes a connected reducer and a motor, which can achieve speed control.

[0029] The small telescopic arm 531 is also fixedly connected to a mounting bracket 535. The small telescopic arm luffing cylinder 533 is hinged to the small telescopic arm 531 via the mounting bracket 535 to improve the stability of the structural installation. Furthermore, the mounting bracket 535 is welded to the small telescopic arm 531 to improve the stability of the small telescopic arm 531 structural installation.

[0030] like Figure 3 and Figure 4 The figure shows the scraper arm in the retracted and operating state in the inclined shaft. The scraper arm, with its multi-angle rotation and pitching movements, can quickly scrape the slag into the pilot shaft. The scraper arm can be mounted on the lower part of the inclined shaft construction trolley to scrape the blasted slag into the pilot shaft chute. This meets the construction scope of the inclined shaft with a diameter of 6 to 8 meters, an inclination angle of 55 to 60 degrees, and a single advance of 2 to 3 meters. The posture of the scraper arm when not in operation does not affect the operation of other booms. In the retracted posture, the scraper arm can be retracted to facilitate the raising of the construction trolley to a safe position (30 meters from the tunnel face) during blasting. In addition, the scraper arm has good operability and high operating efficiency.

[0031] It is worth mentioning that, if Figure 3 As shown, the scraper arm can also be equipped with a manned platform 501, and workers can stand on the platform to perform operations such as anchoring and grouting.

[0032] like Figure 2-4 As shown, the present invention also provides an underground operation trolley, comprising a scraper arm 50 and a trolley frame 10. The scraper arm 50 is mounted on the trolley frame 10. A track is installed in the well, and the trolley frame 10 runs along the track, carrying the scraper arm 50 to operate at different positions in the well. It is worth noting that the operation trolley is also equipped with a spraying device. The grouting head of the spraying device is mounted on the arm frame of the scraper arm 50. The movement of the arm frame drives the grouting head to spray magma onto the rock wall.

[0033] The slag scraping arm provided in the embodiment of the present invention can drive the small telescopic arm assembly 53 to rotate 360° around the connection point through the rotation of the rotating platform 57, thereby realizing 360° free slag scraping by the slag scraping arm. At the same time, the platform seat variable amplitude cylinder 573 is actuated to control the pitch angle of the small telescopic arm assembly 53, thereby expanding the operating range of the bucket 59. During the operation, slag scraping operations can be carried out over a large range without moving the work trolley, which greatly improves work efficiency.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
