Technical Field

[0001] The utility model relates to the technical field of construction of pedestrian walkways in river ecosystems, in particular to a precision control device for rapid installation of pedestrian walkway panels in river ecosystems. Background Art

[0002] Existing river ecosystem pedestrian walkways are assembled using precast concrete slabs. The total width of the slabs is 2.5 meters, with each slab measuring 1 meter long. The bottom 1.5 meters are attached to the top of the riverbank retaining wall, and the remaining 1 meter is a cantilevered portion. During installation, these slabs are often hoisted using a crane. For the cantilevered portion, the crane adjusts the hoisting height up and down to adjust the elevation and straightness of the slab. However, this conventional construction process is costly for machinery, difficult to control elevation, and results in low installation accuracy. Furthermore, it cannot guarantee the overall straightness of the pedestrian walkway. Utility Model Content

[0023] The telescopic assembly 3 comprises a sleeve and a telescopic tube that are interconnected. The sleeve is sleeved onto the outside of the telescopic tube and is fixedly connected to the lifting assembly 2. The telescopic tube is connected to the output end of the lifting assembly 2. The lifting assembly 2 can drive the telescopic tube to move up and down relative to the sleeve. A steel plate is fixed to the top of the telescopic tube for contact with the concrete promenade slab. To prevent damage to the concrete promenade slab during lifting, a rubber pad 8 is installed on top of the steel plate. Preferably, both the sleeve and the telescopic tube are steel pipes.

[0024] Furthermore, the jacking assembly 2 includes a mounting frame 7 and a jack. Specifically, the mounting frame 7 is enclosed by four steel plates, and the jack is installed within the mounting frame 7. At this point, the bottom end of the casing is fixedly connected to the top plate of the mounting frame 7 and communicates with each other. The bottom end of the telescopic tube extends downward into the mounting frame 7 and is connected to the output end of the jack. The jack can drive the telescopic tube to move up and down relative to the casing. Preferably, the jack is a hand-cranked hydraulic jack, which can be used to fine-tune the height of the concrete promenade slab.

At this time, the height can be dynamically adjusted according to the height of the retaining wall below the concrete promenade slab. In addition, a base plate 6 is fixedly connected to the bottom of the lower support tube 9 to increase the contact area between the lower support tube 9 and the ground and improve the stability of the overall structure. Preferably, the upper support tube 4 and the lower support tube 9 are both steel tubes, and the base plate 6 is a steel plate. The lower support tube 9 and the base plate 6 are connected by welding.

[0027] The precision control device for the rapid installation of pedestrian walkway panels in river ecosystems of the present invention can dynamically adjust the height according to the height of the retaining wall below the pedestrian walkway by setting a telescopic component 3, a lifting component 2 and a supporting component 1. At the same time, the height can be fine-tuned by a hand-cranked hydraulic jack to ensure the installation height and installation straightness of the cantilevered part of the pedestrian walkway, solving the problem of low installation straightness of the pedestrian walkway caused by the up and down adjustment of the elevation of the cantilevered part of the pedestrian walkway controlled by a crane; and, due to the adjustability of the lower supporting component 1 and the adjustability of the height of the middle lifting component 2, dynamic adjustment can be made according to the cantilever height below the pedestrian walkway panel and the river slope to be suitable for the installation of pedestrian walkway panels in various river ecosystems.
