Description

Technical Field

[0001] This utility model relates to the field of aerial work equipment technology, and in particular to a wheeled aerial work trolley with multiple degrees of freedom that is flexible and adaptable to special scenarios such as mines. Background Technology

[0002] Aerial work platforms are essential equipment for working at heights, widely used in construction, equipment installation, and municipal maintenance. They typically use a wheeled chassis as their mobile platform, and, together with a telescopic boom and work platform, allow for adjustments to the working position at height, providing stable support for operators.

[0003] With the development of mining technology, the demand for high-altitude operations inside mines, such as equipment installation, roof / sidewall maintenance, and pipeline laying, is increasing. The mine environment differs significantly from conventional ground environments: firstly, mine passageways are narrow and have complex terrain, with some areas having limited height and irregular orientations, placing extremely high demands on the mobility and spatial adaptability of the work equipment; secondly, mine operations need to address multi-directional work requirements, necessitating not only roof support and reinforcement and lighting installation, but also the maintenance of pipelines and monitoring equipment on the sidewalls, requiring work platforms with flexible multi-directional adjustment capabilities; furthermore, the potential for falling rocks and dust inside mines places special demands on the protective performance of equipment and personnel.

[0004] Existing wheeled aerial work platforms have the following shortcomings when used in mine environments: First, they have limited operational freedom, with telescopic booms typically only capable of lifting or rotating in a single direction, making them unsuitable for multi-directional operations within the confined spaces of mines. Second, the platform's position adjustment flexibility is insufficient; most platforms can only move as a whole with the telescopic boom, unable to achieve fine adjustments such as left-right or rotational movements within a small local area, limiting operation when working close to the mine's side walls. Third, the protective structures have poor adaptability; existing equipment's protective devices are mostly designed for falling objects from the ground, neglecting the specific protection needs inside mines, and the protection strength of the cab and platform is insufficient. Fourth, the equipment's adaptability to the mine environment is weak; some equipment, due to its large size or cumbersome steering and telescopic structures, is prone to collisions when moving in narrow mine passages, and may even be unable to enter the work area. Fifth, the work platform lacks a dedicated control panel; operators must control the platform's movements from the cab or with the aid of external equipment, making it difficult to adjust the platform's position accurately and in real time during operations, thus affecting work efficiency.

[0005] Therefore, developing a wheeled aerial work platform suitable for mining scenarios, with high mobility, multi-degree-of-freedom adjustment capabilities, reliable protective performance, and easy operation has become the key to solving the problem of high-altitude operations in mines.

[0012] As a further improvement, a guide telescopic device is rotatably connected to the working platform via a second rotary cylinder.

[0017] 1. This utility model achieves the left and right rotation of the telescopic boom hinge seat through a rotating support and a rotating cylinder, and drives the multi-stage boom to rotate up and down with the support cylinder. Combined with the axial extension and retraction of the multi-stage boom and the rotation of the working platform driven by the platform hinge seat and the rotating cylinder, the working platform can be moved left and right along the platform chassis through a push-pull cylinder, forming a multi-dimensional adjustment system.

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1-5 As shown, a multi-degree-of-freedom, flexible wheeled aerial work platform includes a wheeled chassis 1. The wheeled chassis 1 serves as the mobile carrier of the equipment and can adopt a four-wheel drive wheeled structure to improve the accessibility of complex terrain in mines. A rotating support 2 is fixed to the front end of the wheeled chassis 1. The rotating support 2 is fixed to the wheeled chassis 1 by bolts or welding. A telescopic arm hinge seat 3 is hinged to the rotating support 2. A rotating cylinder 4 is provided on one side of the telescopic arm hinge seat 3. The two ends of the rotating cylinder 4 are hinged to the rotating support 2 and the telescopic arm hinge seat 3, respectively. Specifically, the hinge can be achieved through pins. When the rotating cylinder 4 extends or retracts, it can drive the telescopic arm hinge seat 3 to rotate left and right relative to the rotating support 2 (the rotation angle can be designed to be ±29°~±80°), realizing the horizontal steering adjustment of the entire telescopic arm.

[0031] A multi-stage arm 5 is hinged to the telescopic boom hinge seat 3. A support cylinder 6 is provided between the telescopic boom hinge seat 3 and the multi-stage arm 5. The two ends of the support cylinder 6 are respectively hinged to the telescopic boom hinge seat 3 and the multi-stage arm 5. When the support cylinder 6 extends or retracts, it drives the multi-stage arm 5 to rotate up and down relative to the telescopic boom hinge seat 3 (the rotation angle can be designed to be 0° to 90°), so as to realize the pitch adjustment of the multi-stage arm 5 and adapt to the working height requirements of the mine top or side wall.

[0032] The other end of the multi-stage boom 5 is hinged to a platform hinge seat 7. The platform hinge seat 7 is rotatably connected to the platform chassis 9 via a rotary cylinder 8. The rotary cylinder 8 can be a swing cylinder, with its fixed end bolted to the platform hinge seat 7 and its movable end fixed to the platform chassis 9. When the rotary cylinder 8 is activated, it drives the platform chassis 9 to rotate left and right relative to the platform hinge seat 7 (the rotation angle can be designed to ±120°), thereby achieving horizontal rotation adjustment of the work platform 10. The work platform 10 is movably connected to the platform chassis 9. The work platform 10 is used to carry operators and tools. The work platform 10 is equipped with an operating console 101, which has control buttons, operating levers, and a display screen, facilitating real-time control of the equipment by the operator.

[0033] In this embodiment, a guide groove 11 is provided on the platform chassis 9 along the left and right direction. The bottom surface of the working platform 10 is fixed with a guide rail 12 that is adapted to the guide groove 11 (the guide rail 12 can adopt a T-shaped or dovetail structure). The guide rail 12 is slidably embedded in the guide groove 11 to ensure the stability of the working platform 10 when it moves. A push-pull cylinder 13 is provided between the working platform 10 and the platform chassis 9. The fixed end of the push-pull cylinder 13 is welded to the platform chassis 9 or connected through an ear seat, and the movable end is connected to the working platform 10. When the push-pull cylinder 13 extends or retracts, it drives the working platform 10 to move left and right along the guide groove 11 (the movement stroke can be designed to be 0-1.5m), so as to realize the fine adjustment of the position of the working platform 10 in a small local range, which makes it easier for operators to approach the working point on the side wall of the mine.

[0034] The multi-stage boom 5 includes a primary boom 51, a secondary telescopic boom 52, and a tertiary telescopic boom 53. The primary boom 51 is hinged to the telescopic boom hinge seat 3. The secondary telescopic boom 52 is slidably installed inside the primary boom 51 (a guide slider can be provided on the inner wall of the primary boom 51, and a corresponding guide groove is provided on the outer wall of the secondary telescopic boom 52). A primary telescopic cylinder 14 is built between the primary boom 51 and the secondary telescopic boom 52. The cylinder barrel of the primary telescopic cylinder 14 is fixed to the primary boom 51, and the piston rod is fixed to the secondary telescopic boom 52. When the primary telescopic cylinder 14 extends or retracts, it pushes the secondary telescopic boom 52 to extend or retract along the axial direction of the primary boom 51. The tertiary telescopic boom 53 is slidably installed inside the secondary telescopic boom 52 (with a guide structure similarly provided). A secondary telescopic cylinder 15 is built between the tertiary telescopic boom 53 and the secondary boom 52. The secondary telescopic cylinder 15 pushes the tertiary telescopic boom 53 to extend or retract along the axial direction of the secondary telescopic boom 52. By cooperating with the first-stage telescopic cylinder 14 and the second-stage telescopic cylinder 15, the overall length of the multi-stage boom 5 can be adjusted (the total telescopic stroke can be designed to be 3-8m), adapting to the working distance requirements of mines of different depths.

[0035] To improve the support stability of the multi-stage boom 5, a support cylinder 16 is provided between the lower plane of the first-stage boom 51 and the telescopic boom hinge seat 3. Support cylinders 27 are provided between the left and right sides of the first-stage boom 51 and the telescopic boom hinge seat 3. The two ends of the support cylinders 16 and 27 are respectively hinged to the first-stage boom 51 and the telescopic boom hinge seat 3. The support cylinder 16 mainly bears the downward support force of the first-stage boom 51, while the support cylinder 217 balances the lateral tilting force of the first-stage boom 51 in the left and right directions. The three work together to ensure that the multi-stage boom 5 does not sway during the up-and-down rotation and telescopic process.

[0036] A platform hinge seat 7 is hinged to one end of the third-stage telescopic boom 53 away from the first-stage boom 51. A support cylinder 3 18 is provided between the lower end of the platform hinge seat 7 and the third-stage telescopic boom 53. The two ends of the support cylinder 3 18 are respectively hinged to the third-stage telescopic boom 53 and the platform hinge seat 7. When the support cylinder 3 18 extends or retracts, it drives the platform hinge seat 7 to rotate up and down relative to the third-stage telescopic boom 53 (the rotation angle can be designed to be ±15°), so as to realize the pitch adjustment of the working platform 10 and facilitate the operator to adjust the working tilt angle.

[0037] A guide telescopic device 20 is rotatably connected to the working platform 10 via a rotary cylinder 19. The two ends of the rotary cylinder 19 are connected to the working platform 10 and the guide telescopic device 20 respectively, and can drive the guide telescopic device 20 to rotate back and forth relative to the working platform 10 (the rotation angle can be designed from 0° to 180°). The top of the guide telescopic device 20 is equipped with a platform protective canopy 21 (the platform protective canopy 21 can be made of steel plate or high-strength plastic plate). A canopy telescopic cylinder 22 is provided between the platform protective canopy 21 and the guide telescopic device 20. The canopy telescopic cylinder 22 drives the platform protective canopy 21 to rise and fall along the guide telescopic device 20. The position of the canopy can be adjusted according to the height of the mine roof to effectively block falling rocks or dust. The fixed end of the rotary cylinder 19 is installed on the working platform 10, and the movable end is connected to the guide telescopic device 20. It can drive the platform protective canopy 21 to rotate left and right relative to the working platform 10 to expand the protection range.

[0038] A driver's cab 23 is mounted on a wheeled chassis 1. A second guide telescopic device 24 is mounted on the driver's cab 23. A protective canopy 25 is mounted on the top of the second guide telescopic device 24 (the protective canopy 25 can be a steel frame structure with protective plates). A lifting cylinder 26 is mounted between the protective canopy 25 and the second guide telescopic device 24. The two ends of the lifting cylinder 26 are connected to the second guide telescopic device 24 and the protective canopy 25 respectively. When the lifting cylinder 26 extends or retracts, it pushes the protective canopy 25 up and down along the second guide telescopic device 24 (the lifting stroke can be designed to be 0.5-1.2m). When the mine roof is low, the height of the protective canopy 25 can be lowered to avoid collisions. When there is a risk of falling rocks, the protective canopy 25 can be raised to form reliable protection.

[0039] The work platform 10 is equipped with a sensor 27 (which can be an infrared distance sensor or an ultrasonic sensor) to prevent collisions. The sensor 27 is electrically connected to the control panel 101 and can display the detected obstacle distance information on the display screen of the control panel 101 in real time. It will also issue an audible and visual alarm when approaching an obstacle. The control panel 101 is also electrically connected to the rotating cylinder 4, the rotary cylinder 8, the push-pull cylinder 13, the first-stage telescopic cylinder 14, the second-stage telescopic cylinder 15, the first support cylinder 16, the second support cylinder 17, the third support cylinder 18, the second rotating cylinder 19, the canopy telescopic cylinder 22, and the lifting cylinder 26. The operator can control the action of each cylinder through the operating lever or button on the control panel 101 to achieve multi-degree-of-freedom adjustment of the work platform 10.
