Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to a multi-functional engineering vehicle for high-altitude operations. Background Technology

[0002] Construction engineering indoor high-altitude operations have long faced pain points such as complex environments, high safety risks, strong reliance on manual labor, and limited efficiency. Although traditional aerial work platforms and simple scaffolding are widely used, falls from heights are frequent, and the stability of work platforms is poor. Traditional scaffolding platforms and quick-assembly platforms rely heavily on manual assembly and disassembly, which is labor-intensive and leads to fatigue, directly affecting work efficiency and continuous working time. There are also significant deficiencies in vertical material transportation, horizontal movement of operating platforms, adjustment of vertical working space, and system safety protection.

[0003] Currently, indoor high-altitude operations in construction projects mainly employ a working mode combining mobile lifting platforms with independent material lifting devices. Mobile lifting platforms achieve vertical lifting via hydraulic or electric systems and are equipped with basic safety railings and anti-slip surfaces; material transportation is accomplished using separate hoists or manual handling. These two types of equipment are structurally independent, each possessing its own dedicated power and control systems.

[0004] However, in existing technologies, the aerial work platform and the material transport system are independent of each other. This results in operators needing to repeatedly adjust the equipment position during aerial work and spending a lot of time coordinating operations in the stages of platform lifting and material transport. This decentralized design seriously affects construction efficiency and increases safety risks during the operation. Utility Model Content

[0020] 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.

[0021] like Figures 1-6 As shown, this utility model proposes a multi-functional engineering vehicle for high-altitude operations, including a material holding mechanism 15 composed of a material hopper 24, an upper-opening baffle 25, a hopper base 27, and a base support column 28, used for holding materials or tools, etc.; as one embodiment, the material holding mechanism 15 includes a material hopper 24, an upper-opening baffle 25 is provided on the top of the material hopper 24, a hopper base 27 is provided at the bottom of the material hopper 24, and a base support column 28 is fixed to the lower surface of the hopper base 27. The material holding mechanism 15 is described in detail below: In this embodiment, the material holding mechanism 15 includes a material hopper 24, with an upper-opening baffle 25 at the top and a hopper base 27 fixed at the bottom. A base support 28 is connected to the lower surface of the hopper base 27. During operation, the material hopper 24 is used to hold materials, the upper-opening baffle 25 facilitates the loading, unloading, and horizontal transportation of materials, and the base support 28 provides support stability to ensure that the materials remain balanced during vertical transportation.

[0022] like Figures 1-5As shown, the multi-functional engineering vehicle also includes an adjustment mechanism for driving the material holding mechanism 15 to move up and down; in one embodiment, the adjustment mechanism includes two sets of rollers 42 that assist the material hopper 24 in moving on the outer wall of the steel guide rail 17. Both sets of rollers 42 are installed on one side of the outer wall of the material hopper 24. Both sets of rollers 42 are provided with traction chains 21 on the outer wall of the two sets of rollers 42. One end of each traction chain 21 is fixed with a wire roller 41. The middle part of the traction chain 21 is guided to the top and bottom of the steel guide rail 17 through the upper drive shaft 20 and the lower drive shaft 19. The two wire rollers 41 are driven by a lifting drive motor 16. Multiple steel crossbeams 18 are provided in the middle of the steel guide rail 17. A connecting fastening device 26 is fixed to one side of the outer wall of the steel guide rail 17. An upper limit device 22 and a buffer base 23 are fixed to the top and bottom of the steel guide rail 17, respectively, for limiting and protecting the material holding mechanism 15. The adjustment mechanism is described in detail below: In this embodiment, the lifting drive motor 16 drives the roller 41 to wind the traction chain 21. The traction chain 21 is guided by the upper drive shaft 20 and the lower drive shaft 19, driving the material hopper 24 to move up and down along the steel guide rail 17. The roller 42 assists the material hopper 24 to move smoothly on the outer wall of the steel guide rail 17. The upper limit device 22 and the buffer base 23 are respectively installed at the top and bottom of the steel guide rail 17. When the material hopper 24 touches the upper limit device 22, the lifting drive motor 16 automatically shuts off the upward force; the buffer base 23 is used to mitigate the impact when the material hopper 24 descends.

[0023] like Figures 1-7 As shown, the multi-functional engineering vehicle also includes a fall prevention component installed at the bottom of the hopper base 27. In one embodiment, the fall prevention component includes a limiting box 29 fixed to the lower surface of the hopper base 27. A sliding plate 30 slides inside the limiting box 29. A locking block 31 slides inside the sliding plate 30, and a limiting plate 32 limits the locking block 31. A sliding rod 33 and a spring 34 are fixed on one side of the outer wall of the limiting plate 32. The spring 34 is sleeved on the outer wall of the sliding rod 33. Both sides of the inner wall of the steel guide rail 17 are fixed with a slot plate 43 designed to mesh with the locking block 31. The fall arrestor assembly includes a rubber damping block 35 that limits the movement of the sliding plate 30. The rubber damping block 35 slides on the inner wall of the limiting box 29, and the limiting box 29 also has a groove that matches the rubber damping block 35. A top push plate 36 is fixed to the upper side of the inner wall of the steel guide rail 17, and a bottom push plate 37 is fixed to the lower side of the inner wall of the steel guide rail 17. The lower surface of the top push plate 36 and the upper surface of the bottom push plate 37 are both designed with slopes, and the outer wall of the bottom push plate 37 can slide into the limiting box 29. The fall arrestor assembly is described in detail below: In this embodiment, when the material holding mechanism 15 is pulled up, the limiting box 29 below the hopper base 27 will move simultaneously. At this time, the locking block 31 inside the sliding plate 30 will slide on the outer wall of the slot plate 43. Since the upper part and the left and right sides of the locking block 31 are designed with inclined surfaces, and with the elastic force of the spring 34, the locking block 31 is pushed to reset, so that the locking block 31 can be locked in the preset groove inside the slot plate 43 when it moves again. If the material holding mechanism 15 falls due to the breakage of the traction chain 21, the locking block 31 can be locked inside the slot plate 43 to support the material holding mechanism 15 and prevent the material holding mechanism 15 from falling rapidly. In addition, when the material holding mechanism 15 moves to the top of the steel guide rail 17, the sliding plate 30 will contact the top push plate 36. At this time, the sliding plate 30 will be pushed into the limit box 29 by the inclined surface below the top push plate 36. At the same time, the sliding plate 30 will also drive the locking block 31 to move into the limit box 29, so as not to affect the lowering of the material holding mechanism 15. When the material holding mechanism 15 moves to the bottom of the steel guide rail 17, the sliding plate 30 will contact the bottom push plate 37 again, and the sliding plate 30 will be pushed out and reset by the inclined surface above the bottom push plate 37. During this process, the rubber damping block 35 will dampen to prevent the sliding plate 30 from moving randomly.

[0024] like Figures 1-5 As shown, the multi-functional engineering vehicle also includes a chassis frame 5 fixed to one side of the bottom of the steel guide rail 17; in one embodiment, the surface of the chassis frame 5 is provided with a horizontal omnidirectional moving walking mechanism, a work platform lifting mechanism, and an aerial work platform; the horizontal omnidirectional moving walking mechanism includes a drive motor 1, a drive control actuator 2, and a transmission device 3 mounted on the upper surface of the chassis frame 5. The drive motor 1 is connected to and drives the shock-absorbing and braking omnidirectional wheels 4 through the transmission device 3. The horizontal omnidirectional moving walking mechanism is described in detail below: In this embodiment, the chassis frame 5 is located at the bottom of the engineering vehicle, and the drive motor 1 drives the shock-absorbing and braking omnidirectional wheels 4 through the transmission device 3. The user inputs forward, reverse, or turning commands through the remote control device. After receiving the signal, the drive control actuator 2 controls the start, stop, and steering of the drive motor 1. The transmission device 3 unlocks the omnidirectional wheel braking device, and after the engineering vehicle moves to the target position, the omnidirectional wheels are locked again to achieve omnidirectional movement and shock-absorbing braking.

[0025] like Figures 1-9As shown, the multi-functional engineering vehicle also includes a work platform lifting mechanism mounted above the horizontal omnidirectional moving mechanism via telescopic support columns 38. In one embodiment, the work platform lifting mechanism includes a lifting motor 6 and a lifting adjustment controller 7. The lifting motor 6 connects to and drives multiple electric telescopic uprights 8, and electric telescopic diagonal bars 9 connect the multiple electric telescopic uprights 8. The lifting adjustment controller 7 is connected to an automatic horizontal adjustment device 10. The work platform lifting mechanism is described in detail below: In this embodiment, the chassis frame 5 is located at the bottom of the engineering vehicle, and the drive motor 1 drives the shock-absorbing and braking omnidirectional wheels 4 through the transmission device 3. The user inputs forward, reverse, or turning commands through the remote control device. After receiving the signal, the drive control actuator 2 controls the start, stop, and steering of the drive motor 1. The transmission device 3 unlocks the omnidirectional wheel braking device, and after the engineering vehicle moves to the target position, the omnidirectional wheels are locked again to achieve omnidirectional movement and shock-absorbing braking.

[0026] like Figures 1-9 As shown, the multi-functional engineering vehicle also includes a high-altitude work platform located above the lifting mechanism of the work platform; as one embodiment, the high-altitude work platform includes an anti-slip work platform 11, the edge of the anti-slip work platform 11 is provided with a toe board 12, a protective upright 13 is connected above the toe board 12, and a protective railing 14 is connected between the protective uprights 13. The telescopic support column 38 has multiple limiting holes 40 inside, and an L-shaped limiting rod 39 that matches the limiting holes 40 is installed inside the telescopic support column 38. The following is a detailed description of the aerial work platform: In this embodiment, the anti-slip working platform 11 of the aerial work platform provides a support platform, and the toe guards 12 set at the edge of the platform effectively prevent tools or materials from accidentally falling from the edge of the platform. The protective poles 13 are vertically fixed around the platform, and the upper part of them is connected to the guardrails 14, which together form a complete perimeter protection mechanism, providing a safe working area for operators and preventing personnel from falling from heights. In addition, the telescopic support column 38 is mechanically fixed by L-shaped limit rods 39 inserted into the limit holes 40 at different heights, providing additional mechanical locking protection for the lifting mechanism and preventing accidental settlement.

[0027] Specifically, when the multi-functional engineering vehicle for high-altitude operations is in operation, the operator controls the operation of the entire machine through a remote control device. The horizontal omnidirectional moving walking mechanism first receives the command, and the drive motor 1 drives the shock-absorbing and braking omnidirectional wheels 4 through the transmission device 3 to achieve omnidirectional movement and positioning of the engineering vehicle. After arriving at the work area, the lifting mechanism of the work platform is activated, and the lifting motor 6 drives the electric telescopic pole 8 and the electric telescopic diagonal pole 9 to extend, raising the high-altitude operation platform to the designated height. During this process, the automatic horizontal adjustment device 10 automatically maintains the platform's horizontal stability.

[0028] Meanwhile, the material holding mechanism 15 operates independently. The lifting drive motor 16 drives the material hopper 24 to transport materials vertically along the steel guide rail 17 via the traction chain 21. When the material hopper 24 rises and touches the upper limit device 22, it stops automatically. When it descends to the bottom, it is buffered by the buffer base 23. If the traction chain 21 breaks or loses speed during operation, the anti-fall component is immediately activated. The locking block 31 engages with the slot plate 43 under the action of the spring 34, locking the material hopper 24 onto the steel guide rail 17.

[0029] Operators can work safely on an aerial work platform equipped with an anti-slip work platform 11, toe board 12, protective uprights 13 and guardrails 14. The L-shaped limit rod 39 in the telescopic support 38 cooperates with the limit hole 40 to provide additional mechanical locking protection, so as to realize the simultaneous operation of high-altitude work and material transportation.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
