[0026] 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.

[0027] like Figures 1-3 As shown, this embodiment provides a high-altitude work device for inclined shaft construction, including: a high-altitude work mechanism 1, a sliding mechanism 2, and a lifting mechanism 3. The aerial work platform 1 includes a work basket 11 and a boom structure. The sliding mechanism 2 includes a sliding trolley 21 and a slide rail 22. The slide rail 22 is installed on the work platform 4 and arranged along the travel direction of the work platform 4. The sliding trolley 21 slides on the slide rail 22. The upper end of the boom structure is connected to the sliding trolley 21. The work basket 11 is installed at the lower end of the boom structure. The lifting mechanism 3 is connected to the sliding trolley 21 and is used to drive the sliding trolley 21 to slide along the slide rail 22 so that the aerial work platform 1 extends to the front of the work platform 4 or retracts to the top of the work platform 4. The boom structure is used to drive the work basket 11 to move within the inclined shaft space so that the work basket 11 reaches the designated position.

[0028] When the aerial work platform 1 is retracted to its position above the work trolley 4, it is in a non-working state. The lifting mechanism 3 fully raises the sliding trolley 21 until it reaches the rear end of the slide rail 22, where it is locked by the upper locking mechanism 23 to restrict its movement and prevent safety risks. In this state, the boom structure of the aerial work platform 1 is fully retracted into the work trolley 4, and the other working devices 41 of the work trolley 4 can operate freely. This state also facilitates workers getting on and off the work basket.

[0029] When the aerial work platform 1 extends to the front of the work trolley 4, the sliding trolley 21 is fully lowered to the front end of the slide rail 22 and locked by two lower locking mechanisms 24 to restrict the movement of the sliding trolley 21 under the working state of the aerial work platform 1, thus avoiding the risk of safety accidents. At this time, the aerial work platform 1 is in working state, and the boom structure can drive the work basket 11 to move back and forth, tilt up and down, and rotate within a certain range, so as to conveniently, quickly and safely transport workers and equipment to the designated work position, and achieve full cross-section coverage for each drilling and blasting advance without moving the main trolley.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the boom structure includes a boom slewing mechanism 12, a telescopic boom 13, and a boom structure 14. The boom slewing mechanism 12, telescopic boom 13, boom structure 14, and work basket 11 are hinged sequentially. The boom slewing mechanism 12 is mounted on the sliding trolley 21 and is used to drive the telescopic boom 13 to rotate 360° in the horizontal direction. When the device is in operation, the angle of the telescopic boom 13 in the vertical plane is controlled by the luffing drive cylinder 16. After the high-altitude operation is completed, the luffing cylinder controls the telescopic boom 13 to be arranged along the travel direction of the work trolley 4 so that the device can be retracted into the work trolley 4. The boom structure 14 is used to drive the work basket 11 to pitch, thereby adjusting the position of the work basket 11 in the vertical direction.

[0031] In this embodiment, an upper leveling drive cylinder 18 is hinged between the boom slewing mechanism 12 and the telescopic boom 13, and a lower leveling drive cylinder 19 is hinged between the telescopic boom 13 and the flying boom structure 14. The upper leveling drive cylinder 18 and the lower leveling drive cylinder 19 are linked for control so that the work basket 11 always remains horizontal during movement.

[0032] In this embodiment, the boom structure 14 includes a boom connecting seat 141, a swing cylinder seat 143, an upper boom 142, and a lower boom 144. The boom connecting seat 141, the upper boom 142, the swing cylinder seat 143, and the lower boom 144 are connected end to end in a parallelogram-like structure. The boom connecting seat 141 is located near the telescopic arm 13, and its portion opposite to the telescopic arm 13 extends toward the telescopic arm 13 and is hinged to the telescopic arm 13. The swing cylinder seat 143 is located near the work basket 11, and its portion opposite to the work basket 11 extends toward the work basket 11 and is connected to the work basket 11. A boom drive cylinder 17 is provided between the upper boom 142 and the lower boom 144.

[0033] In this embodiment, a variable amplitude drive cylinder 16 is also hinged between the boom slewing mechanism 12 and the telescopic boom 13 to adjust the angle of the telescopic boom 13 in the vertical plane.

[0034] Specifically, the boom slewing mechanism 12 includes a boom slewing drive mechanism 121 and a slewing turntable 122. The telescopic boom 13 includes a telescopic outer boom 131 and a telescopic inner boom 132. The boom slewing drive mechanism 121 includes a fixed end and a slewing end rotatably connected to the fixed end. Its fixed end is mounted on the sliding trolley 21, and its slewing end is fixed to the slewing turntable 122. The slewing turntable 122 is hinged to one end of the telescopic outer boom 131. One end of the telescopic inner boom 132 is slidably disposed inside the telescopic outer boom 131, and the other end of the telescopic inner boom 132 is hinged to the boom structure 14.

[0035] The boom slewing drive mechanism 121 can be driven by a motor to rotate its slewing end; the motor can be mounted on the sliding trolley 21. The turntable 122 is arranged horizontally, thereby enabling the boom slewing drive mechanism to achieve 360° rotation of the aerial work platform 1 in the horizontal direction. By extending the telescopic inner boom 132 out of or retracting it into the telescopic outer boom 131, the work basket is driven to move forward or backward along the axis of the telescopic boom 13.

[0036] The extended end of the boom drive cylinder 17 is hinged to the boom connecting seat 141 and the hinged end of the upper boom 142. The fixed end of the boom drive cylinder 17 is hinged to both the upper boom 142 and the lower boom 144. The hinge position between the upper boom 142 and the boom drive cylinder 17 is about one-third of the way from the work basket 11, and the hinge position between the lower boom 144 and the boom drive cylinder 17 is about one-half of the way from the work basket 11.

[0037] In this embodiment, the working basket 11 and the swing cylinder seat 143 are connected by a working basket rotation drive mechanism 15, which is used to drive the working basket 11 to rotate within a set range in the horizontal direction.

[0038] Equipped with a boom structure, the vertical pitch angle can reach ±65°, allowing for vertical position adjustment of the aerial work basket without adjusting the telescopic boom. A rotating work platform mechanism allows for horizontal angle adjustment of the aerial work basket. This aerial work platform is highly flexible, safe, and has a wide operating range, achieving full cross-section coverage for each drilling and blasting advance without moving the main trolley.

[0039] The work basket rotation drive mechanism 15 enables the work basket to swing left and right at a small angle when the boom is not in motion, thus achieving fine adjustment of the work basket in the left and right directions.

[0040] Specifically, the work basket 11 includes a base plate 111 and a guardrail 112. The base plate 111 is horizontally arranged, and the guardrail 112 surrounds the upper surface of the base plate 111. That is, the work basket 11 is vertically arranged. Under the linkage control of the upper leveling drive cylinder 18 and the lower leveling drive cylinder 19, during the pitching process of the flying arm structure 14 driving the work basket 11, the base plate 111 of the work basket 11 always remains horizontal to ensure the safety of personnel and the stability of transported materials.

[0041] In addition, hanging points and lifting devices can be added to the lower end of the work basket 11 to assist in hoisting and realize the multi-purpose function of this device.

[0042] In this embodiment, as Figure 8 As shown, the upper end of the slide rail 22 is provided with an upper locking mechanism 23, which is used to lock the sliding trolley 21 when the aerial work mechanism 1 is retracted to a position above the work platform 4. The lower end of the slide rail 22 is provided with a lower locking mechanism 24, which is used to lock the sliding trolley 21 when the aerial work mechanism 1 is extended to a position in front of the work platform 4.

[0043] The upper locking mechanism 23 and the lower locking mechanism 24 can be made of conventional track brakes, which will not be described in detail here.

[0044] In this embodiment, as Figure 7 As shown, the lifting mechanism 3 includes a winch 31, a pulley 32 and a wire rope 33. The winch 31 is fixed on the work trolley 4, the pulley 32 is rotatably mounted on the work trolley 4, one end of the wire rope 33 is fixed to the winch 31, and the other end passes through the winch 31 and the pulley 32 and is fixed to the sliding trolley 21.

[0045] Example 2: This embodiment provides an inclined shaft construction device, including a work platform 4 and an aerial work device as described in Embodiment 1, such as... Figure 1 As shown, the slide rail 22 of the aerial work platform is installed on the uppermost support of the work platform 4.

[0046] like Figure 2 and Figure 3As shown, a typical inclined shaft construction involves excavating a B-diameter inclined shaft 6 and a A-diameter inclined shaft 5. The B-diameter inclined shaft 6 is located above the A-diameter inclined shaft 5, and the work trolley 4 is located inside the A-diameter inclined shaft 5. A steel plate is laid on the bottom surface of the A-diameter inclined shaft 5 as a track surface for the work trolley 4 to travel on. Each section of the inclined shaft requires anchor bolt installation, grouting, installation of protective netting, track laying, and placement of explosives. Previously, these operations required workers to be suspended by safety ropes, which was highly dangerous and labor-intensive. This invention adds the aerial work platform of Embodiment 1 to the work trolley 4. It is equipped with an engineering machinery aerial work boom and a work basket, offering high flexibility, high safety, and a wide operating coverage area. It can achieve full-section coverage of each drilling and blasting advance without moving the main trolley. A trolley sliding mechanism is also designed to allow for the extension and complete retraction of the aerial work platform. When fully retracted, it does not affect the operation of other work devices 41, thus greatly expanding the functionality of the drilling and blasting work trolley.

[0047] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
