Description
Technical Field
[0001] This utility model relates to the field of tunnel construction technology, and in particular to a multi-functional construction trolley. Background Technology
[0002] Currently, my country is vigorously constructing highways, and tunnel construction is also frequent. However, large machinery cannot enter the tunnels during construction, relying heavily on manual labor, especially for cargo transportation. This involves high labor intensity, a large workload, and relatively low work efficiency. With the development of road construction, the number of highway tunnels is increasing. During construction, multi-functional trolleys are needed to assist construction workers. Since lighting inside tunnels is poor, these trolleys need to illuminate the tunnel roads to facilitate construction. However, existing highway tunnel construction trolleys provide poor illumination of the roads on both sides of the tunnel, making it difficult for workers to directly observe road conditions and increasing the risk of accidents. Furthermore, the trolleys are too large to maneuver freely in confined spaces, hindering workers from accessing materials at specific locations. Additionally, the height of the trolley's cargo box is generally fixed, making it impossible to provide materials to workers at higher positions. Utility Model Content

The top surface of the installation platform 4 is provided with a rotation component and an annular guide rail component to support the rotation of the box 5.
[0033] A height adjustment mechanism is located between the support platform 1 and the installation platform 4 to adjust the height of the housing 5.
[0034] Box 5, located on the top surface of the rotating assembly, is used to load and transport materials;
[0035] The lighting mechanism includes lighting components arranged in a rectangular shape at the four corners of the top surface of the box 5, which are used to illuminate the external road of the trolley and the interior of the box 5.
[0036] Both the support platform 1 and the installation platform 4 are set in a horizontal direction.
[0037] In a preferred embodiment, the height adjustment mechanism includes a linear guide rail assembly, an X-shaped hinge frame 8, and a first drive assembly; wherein,
[0038] The linear guide assembly includes a first linear guide 6 symmetrically fixed on the top surface of the support platform 1, and a second linear guide 7 symmetrically fixed on the bottom surface of the mounting platform 4 corresponding to the first linear guide 6; the two first linear guides 6 and the two second linear guides 7 are arranged in a rectangular shape; each first linear guide 6 and each second linear guide 7 is provided with two sliders.
[0039] There are two X-shaped hinge frames 8 arranged parallel to each other, one on the top and one on the bottom of the first linear guide rail 6 and the other on the second linear guide rail 7. That is, the support platform 1 and the mounting platform 4 are connected and supported by the two X-shaped hinge frames 8. The four ends of the X-shaped hinge frames 8 are respectively hinged to the four sliders of the corresponding first linear guide rail 6 and the second linear guide rail 7, and are used to adjust the height of the mounting platform 4. There can be multiple X-shaped hinge frames 8 arranged vertically, and the vertically distributed X-shaped hinge frames 8 are also hinged to each other to increase the height adjustment range of the mounting platform 4.
[0040] The first drive assembly includes a fixed upright plate 9 fixedly disposed on the top surface of the support platform 1 at both ends of the two first linear guide rails 6. An electric hydraulic rod 10 is fixedly disposed on the top surface of the support platform 1. One end of the electric hydraulic rod 10 is fixedly disposed on the inner side of the corresponding fixed upright plate 9, and the other end is fixedly connected to the slider on the corresponding first linear guide rail 6 for adjusting the height of the corresponding X-shaped hinge frame 8.
[0041] The electric hydraulic rod 10 drives the slider on the corresponding first linear guide rail 6 to move, causing the corresponding X-shaped hinge frame 8 to retract (increase in height) or expand (decrease in height), thereby achieving adjustment of the overall height of the installation platform 4 and the box 5.
[0042] In a preferred embodiment, the rotating assembly includes a lower rotating bearing 11 fixedly disposed on the top surface of the mounting platform 4. A rotating column 12 is rotatably disposed between the lower rotating bearing 11 and the bottom surface of the housing 5. That is, the top end of the rotating column 12 is fixedly connected to the bottom surface of the housing 5, and the bottom end is fixedly connected to the inner ring transmission surface of the lower rotating bearing 11, thereby realizing the rotation of the housing 5 relative to the mounting platform 4. A worm gear 13 is fixedly sleeved on the outer circumferential side of the rotating column 12. Support plates 14 are symmetrically fixedly disposed on the top surface of the mounting platform 4. A worm gear 15 is rotatably disposed between the two support plates 14. One end of the worm gear 15 rotatably protrudes through one of the support plates 14. A drive motor 16 is fixedly disposed on the top surface of the mounting platform 4. The transmission end of the drive motor 16 is fixedly connected to the protruding end of the worm gear 15, for driving the worm gear 15 to rotate and drive the worm gear 13, the rotating column 12 and the housing 5 as a whole to rotate.
[0043] Since the rotating column 12 is fixedly connected to the housing 5, the drive motor 16 drives the worm gear 15 to rotate, the worm gear 15 drives the worm wheel 13 to rotate, the worm wheel 13 drives the rotating column 12 to rotate, and the rotating column 12 rotates, thus the housing 5 rotates.
[0044] In a preferred embodiment, the annular guide rail assembly is disposed on the circumferential outer side of the rotating assembly to improve the stability of the housing 5 during rotation. It includes an annular guide rail 17 fixedly disposed on the top surface of the mounting platform 4, and the number of sliders on the annular guide rail 17 is set to be no less than three. A vertical connecting post 18 is fixedly disposed on the top surface of the sliders on the annular guide rail 17, and the end of the connecting post 18 away from the annular guide rail 17 is fixedly connected to the bottom surface of the housing 5.
[0045] In a preferred embodiment, the lighting assembly includes a mounting groove 19 disposed at a corresponding corner of the top surface of the housing 5, a vertically upward electric lifting column 20 fixedly disposed at the bottom of the mounting groove 19, and a lighting lamp 21 fixedly disposed at the top transmission end of the electric lifting column 20.
[0046] In a preferred embodiment, a power supply battery is fixedly installed on the top surface of the support platform 1 between two X-shaped hinge frames 8. The electric lifting column 20, the lighting lamp 21, the drive motor 16 and the electric hydraulic rod 10 are all electrically connected to the power supply battery.
[0047] The working principle of this utility model:
[0048] In use, materials are placed inside the box 5, and then the trolley is pushed or pulled into the tunnel by pushing or pulling the handrail 3. The lighting is raised by activating the electric lifting column 20 to illuminate the tunnel road and the inside of the box 5. After reaching the designated position, the electric hydraulic rod 10 is activated to drive the two sliders on the corresponding first linear guide rail 6 to move towards each other, raising the height of the X-shaped hinge frame 8, thereby realizing the overall height adjustment of the installation platform 4 and the box 5, providing convenience for construction personnel at high positions to access the materials inside the box 5. In addition, if the position of the construction personnel at high positions is fixed and cannot be moved, the drive motor 16 is activated to drive the worm gear 15 to rotate, which drives the worm wheel 13 to rotate, which in turn drives the rotating column 12 to rotate, thereby rotating the box 5. Materials inside the box 5 away from the construction personnel can also be easily accessed and used.
