Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a rapid paving device for sidewalk slabs. Background Technology

[0002] Sidewalks are a crucial component of urban infrastructure. Their paving efficiency and construction quality directly impact the overall speed of municipal road construction and significantly influence pedestrian safety, comfort, and the road's lifespan. Currently, sidewalk slab paving primarily relies on traditional methods. In these methods, the transportation of sidewalk slabs depends heavily on manual handling or simple tools, resulting in extremely low efficiency. Firstly, individual sidewalk slabs are typically heavy and bulky, requiring 2-3 people to lift them manually, with only 1-2 slabs carried at a time. Secondly, the slab storage area is often some distance from the paving area, necessitating repeated trips between the two locations. This excessive number of slab handling operations significantly slows down the overall construction progress, extends the construction period, and forces workers into prolonged periods of high-intensity labor, increasing the risk of fatigue and operational errors. Moreover, when the slabs are delivered to the paving area, the construction workers need to manually move them repeatedly to check their positions in order to achieve proper paving. This is not only cumbersome and difficult, but also time-consuming and labor-intensive. Utility Model Content

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0014] (1) The present invention provides a rapid paving device for sidewalk slabs. This device includes a movable gantry crane and a transport mechanism, with the transport mechanism having a chute. The movable gantry crane has a crossbeam, a lifting assembly, two support legs, and two movable base rods. One end of each movable base rod has an extension, and the inner wall of the extension has a slider adapted to the chute. Through the coordinated use of these components, it not only facilitates the simultaneous transport of multiple sidewalk slabs to the paving area by construction workers, reducing the number of times sidewalk slabs are moved and improving construction efficiency, but also assists construction workers in paving the sidewalk slabs, reducing construction difficulty. Furthermore, it facilitates the transportation and storage of the rapid paving device for sidewalk slabs.

[0015] (2) The sidewalk slab rapid paving device provided by this utility model has a transverse T-shaped cross section for both the chute and the slider, and the upper and lower ends of the slider's vertical plate are respectively provided with mounting grooves. The first roller is rotatably connected in the mounting groove. Through the cooperation of the above components, it can not only effectively prevent the slider from swinging in the up and down direction during the sliding process in the chute, ensuring the stability of the sliding connection between the movable gantry crane and the transport mechanism, but also effectively reduce the frictional resistance between the slider and the chute, making the slider move along the chute more effortless and smooth, and further improving the convenience and efficiency of adjusting the position of the movable gantry crane relative to the transport mechanism.

[0016] (3) The present invention provides a pedestrian slab rapid paving device. By setting a limiting plate at the upper and lower ends of the inner side wall of the movable bottom rod along the length direction, and making the horizontal frame of the chute between the two limiting plates, the structural shaking during sliding can be reduced by the clamping support of the horizontal frame of the chute by the two limiting plates, and the stability of the movable gantry crane relative to the transport mechanism in the left and right movement is further improved.

[0017] (4) The present invention provides a rapid paving device for sidewalk slabs. A limiting sheath is movably provided at one end of the limiting plate above the slider. The horizontal frame of the slide groove has a first limiting hole and a second limiting hole. Through the cooperative use of the above components, not only can the limiting sheath be inserted into the first limiting hole to limit and fix the movable gantry crane and the transport mechanism when multiple sidewalk slabs need to be transported to the paving area or when the rapid paving device for sidewalk slabs needs to be transported or stored, effectively preventing the movable gantry crane from moving left or right when not in use, thus improving the connection stability between the movable gantry crane and the transport mechanism, but also the limiting sheath can be inserted into the second limiting hole to limit and fix the movable gantry crane and the transport mechanism when the lifting assembly lowers the sidewalk slab, effectively preventing the sidewalk slab from swaying due to left or right movement of the movable gantry crane during use, thus improving the stability of the lifting assembly.

Detailed Implementation

[0029] To better understand the purpose, structure, and function of this utility model, the following detailed description of a rapid paving device for sidewalk slabs provided by this utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.

[0030] Please see Figures 1 to 9As shown in the embodiment of this application, a rapid paving device for sidewalk slabs is provided, including a movable gantry crane 10 and a transport mechanism 20 slidably connected to the inner side of the movable gantry crane 10; a slide groove 21 is provided on both sides of the transport mechanism 20 along the length direction; the movable gantry crane 10 includes a crossbeam 11, a lifting assembly 12, two support legs 13 and two movable base rods 14; the lifting assembly 12 is disposed on the crossbeam 11; the upper ends of the two support legs 13 are respectively fixed to the bottom sides of the crossbeam 11, and the lower ends of the two support legs are respectively fixed to the two movable base rods 14; one end of the movable base rod 14 forms an extension 14a, and a slider 14b adapted to the slide groove 21 is provided on the inner side wall of the extension 14a; the movable gantry crane 10 is slidably connected to the slide groove 21 through the slider 14b, and the movable gantry crane 10 can move the sidewalk slab 30 on the transport mechanism 20 to the outside of the transport mechanism 20 through the lifting assembly 12. The transport mechanism 20 includes a base 22 and four sets of rollers arranged side-by-side at the bottom of the base 22; a push rod 22a is provided on the top of the base 22; the roller sets include two second rollers 23; and two sliding grooves 21 are respectively fixed to both sides of the base 22. Multiple sidewalk slabs 30 can be pre-stacked on the base 22. Multiple grooves are equally spaced around the central axis on the upper surface of the sidewalk slab 30; the cross-section of the grooves is an inverted trapezoid; and lifting lugs are pre-embedded inside the grooves so that the lifting assembly 12 can lift the sidewalk slab 30.

[0031] Because the device is equipped with a movable gantry crane 10 and a transport mechanism 20, and the transport mechanism 20 is provided with a chute 21, the movable gantry crane 10 is provided with a crossbeam 11, a lifting assembly 12, two support legs 13, and two movable base rods 14. One end of the movable base rod 14 forms an extension 14a, and the inner sidewall of the extension 14a is provided with a slider 14b that matches the chute 21. Through the cooperation of the above components, it is not only convenient for construction workers to transport multiple sidewalk slabs 30 to the paving area at the same time, reducing the number of times the sidewalk slabs 30 are moved and improving construction efficiency, but it can also assist construction workers in paving the sidewalk slabs 30, reducing the difficulty of construction. In addition, it can also facilitate the transportation and storage of the sidewalk slab rapid paving device.

[0032] Specifically, by setting up the transport mechanism 20, multiple sidewalk slabs 30 can be transported simultaneously to the paving area, making it convenient for construction workers to pick them up. This eliminates the need for repeated transport between the slab stacking area and the paving area, reducing the number of times construction workers need to handle the sidewalk slabs 30 and improving construction efficiency. By setting grooves 21 along the length direction on both sides of the base 22 of the transport mechanism 20, and setting an extension 14a on the movable base rod 14, with a slider 14b adapted to the groove 21 on the inner side wall of the extension 14a, a sliding connection is achieved between the movable gantry crane 10 and the transport mechanism 20. This allows for flexible adjustment of the relative position of the movable gantry crane 10 on the transport mechanism 20, facilitating the hoisting and paving of the sidewalk slabs 30. The operation is simple and convenient, effectively reducing the labor intensity of construction workers and improving paving efficiency. That is, after the lifting assembly 12 lifts the sidewalk slab 30, the construction workers can move the sidewalk slab 30 from the transport mechanism 20 to above the paving position by moving the movable gantry crane 10. Simultaneously, the workers can fine-tune the sidewalk slab 30 by pulling the lifting platform 12c of the lifting assembly 12 to accurately lower it to the paving position, thus achieving one-time paving of the sidewalk slab 30. After the paving work is completed, the movable gantry crane 10 can be moved closer to the push rod 22a, thereby shortening the overall length of the rapid sidewalk slab paving device for easier transportation and storage. Furthermore, it should be noted that after the sidewalk slab 30 is installed, joint filling is required. Waterproof sealant strips are first inserted into the joints, followed by asphalt adhesive. Asphalt adhesive is first applied to the lifting points of the sidewalk slab 30, followed by repair with permeable mortar.

[0033] In a preferred embodiment, both the slide groove 21 and the slider 14b have a transverse T-shaped cross-section. The upper and lower ends of the vertical plate of the slider 14b each have a mounting groove 14c, and at least one first roller 14d is rotatably connected within the mounting groove 14c to facilitate movement of the slider 14b. The slide groove 21 includes a sliding cavity and a horizontal frame; the sliding cavity is fixed to the base 22; the horizontal frame is fixed to the side wall of the sliding cavity near the extension 14a and communicates with the sliding cavity; the slider 14b includes a vertical plate and a horizontal plate; the vertical plate is located within the sliding cavity; one end of the horizontal plate is fixedly connected to the extension 14a, and the other end extends into the sliding cavity and connects to the vertical plate. In this embodiment, three first rollers 14d are rotatably connected within the mounting groove 14c, and the three first rollers 14d are equally spaced along the length of the mounting groove 14c.

[0034] Since both the slide groove 21 and the slider 14b have a transverse T-shaped cross-section, and the upper and lower ends of the vertical plate of the slider 14b are respectively provided with mounting grooves 14c, and the first roller 14d is rotatably connected in the mounting groove 14c, the cooperation of the above components can not only effectively prevent the slider 14b from swinging in the up and down direction during the sliding process in the slide groove 21, ensuring the stability of the sliding connection between the movable gantry crane 10 and the transport mechanism 20, but also effectively reduce the frictional resistance between the slider 14b and the slide groove 21, making the movement of the slider 14b along the slide groove 21 more effortless and smooth, and further improving the convenience and efficiency of adjusting the position of the movable gantry crane 10 relative to the transport mechanism 20.

[0035] In a preferred embodiment, a limiting plate 14e is provided at the upper and lower ends of the inner sidewall of the movable base rod 14 along the length direction; the horizontal frame of the slide groove 21 is located between the two limiting plates 14e.

[0036] By setting a limiting plate 14e at the upper and lower ends of the inner sidewall of the movable base rod 14 along the length direction, and making the horizontal frame of the slide 21 located between the two limiting plates 14e, the two limiting plates 14e can clamp the horizontal frame of the slide 21, reduce the structural shaking during sliding, and further improve the stability of the movable gantry crane 10 relative to the transport mechanism 20 when moving left and right.

[0037] In a preferred embodiment, a limiting sheath 14f is movably disposed at one end of the limiting plate 14e located above the slider 14b; a first limiting hole 21a is provided through the end of the horizontal frame of the slide groove 21 away from the forward end of the transport mechanism 20; a second limiting hole 21b is provided through the end of the horizontal frame of the slide groove 21 near the forward end of the transport mechanism 20; the limiting sheath 14f can be inserted and engaged with the first limiting hole 21a or the second limiting hole 21b.

Furthermore, by inserting the limiting sheath 14f into the second limiting hole 21b, the lifting assembly 12 can limit and fix the movable gantry crane 10 and the transport mechanism 20 when lowering the sidewalk slab 30, effectively preventing the sidewalk slab 30 from swaying due to the left and right movement of the movable gantry crane 10 during use, thereby improving the stability of the lifting assembly 12.

[0039] In a preferred embodiment, the lifting assembly 12 includes a lifter 12a, a first sling 12b, a lifting platform 12c, at least three second slings 12d, a hook 12e, and a controller 12f.

At least three second slings 12d are used to prevent the sidewalk slab 30 from tilting or overturning due to uneven force during lifting. Furthermore, the hinged connection between the second slings 12d and the lifting platform 12c allows for easy angle adjustment of the second slings 12d.
