Description

Technical Field

[0001] This utility model relates to the field of concrete cutting technology, and in particular to a device for precise positioning of concrete cutting joints on airport pavement. Background Technology

[0002] Airport pavement is an artificial structure paved with road-building materials on top of a natural soil base and subbase. It covers areas such as runways, taxiways, and aprons, providing support for aircraft takeoff, landing, taxiing, and parking. It must meet technical requirements such as strength, flatness, and skid resistance. Based on materials, it is divided into two categories: rigid (cement concrete) and flexible (asphalt, gravel). When using a concrete cutter to cut airport pavement, a positioning device is required to position the cut.

[0003] As shown in the reference case "A Concrete Surface Cutting and Positioning Device" (Announcement No. CN220555896U), by setting a U-shaped seat, an ear seat, and a connecting block, the tilt angle of the angle steel on the horizontal plane can be adjusted by rotation, thereby making the angle steel suitable for graphite lines with different tilt angles on the concrete surface, thus increasing the applicable working range and improving practicality. By setting an adjusting external thread shaft, an external thread hollow shaft, an internal thread through hole, and a second bolt, the total length between the adjusting external thread shaft and the external thread hollow shaft can be adjusted, thereby effectively preventing the adjusting external thread shaft and the external thread hollow shaft from obstructing the adjustment of the distance between two adjacent angle steels, thus facilitating the adjustment of the position of the two angle steels.

[0004] According to the above references, in the above device, the limiting screw sleeve is loosened clockwise, and the external thread hollow shaft and the adjusting external thread shaft move along the second rectangular groove until the distance between the end of the angle steel away from the L-shaped plate and the limiting screw sleeve meets the cutting length. The cutting device is then operated to cut along the vertical face of the angle steel to the concrete ground. However, when the device cuts the concrete of the airport pavement, the angle steel is prone to deflection when it comes into contact with the cutting device, which affects the verticality of the concrete cut and makes it inconvenient to position the concrete cut to prevent deflection, thus reducing the effectiveness of the concrete cut positioning device. Utility Model Content

[0005] Therefore, it is necessary to provide a device for precise positioning of concrete cut joints in airport pavements to address the problem of inconvenience in positioning and preventing displacement of concrete cut joints.

[0006] The device includes a fixed plate with a limiting plate on one side; a positioning mechanism for positioning concrete cuts and maintaining vertical cutting, the positioning mechanism being located on one side of the fixed plate; wherein the positioning mechanism includes a sliding rod fixedly connected to one side of the limiting plate, the other end of the sliding rod being slidably connected to the inner wall of the fixed plate, a threaded rod being rotatably connected to one end of the inner wall of the fixed plate, one end of the threaded rod being threadedly connected to the inner wall of the sliding rod, and several evenly arranged ball bearings being rotatably connected to one side of both the fixed plate and the limiting plate, and a fixing component being provided on the other side of the fixed plate.

[0007] In one embodiment, the positioning mechanism further includes a bubble tube fixedly connected to both ends of the top of the fixing plate and the limiting plate, the bubble tube being horizontally installed on the top of the fixing plate and the limiting plate.

[0008] In one embodiment, a support rod is fixedly connected to one side of the limiting plate, and the support rod is disposed on one side of the sliding rod.

[0009] In one embodiment, one end of the support rod is slidably connected to the inner wall of the fixed plate.

[0010] In one embodiment, sliders are fixedly connected to both sides of the sliding rod and the support rod, and the sliders are engaged with both ends of the inner wall of the fixed plate.

[0011] In one embodiment, the fixing component includes several fixing blocks that are evenly arranged and fixedly connected to the other side of the fixing plate, and several counterweights that are evenly arranged are provided on the other side of the fixing blocks.

[0012] In one embodiment, two fixing rods are fixedly connected to the top of the other side of the fixing block, and one end of each fixing rod passes through several of the counterweight blocks in sequence.

[0013] In one embodiment, a nut is threaded to the top of the fixing rod, and the nut is disposed at the top of the counterweight. Beneficial effects

[0014] 1. The above-mentioned precise positioning device for cutting concrete joints on airport pavement includes a fixed plate that is slidably connected to a limiting plate. Both the fixed plate and the limiting plate have a vertical plane structure on one side, which can guide the concrete joint cutting and prevent the cutting device from deviating during the cutting process. The ball bearings on one side of the fixed plate and the limiting plate can contact and limit the cutting device as the fixed plate and the limiting plate approach each other, keeping the cutting device running in a straight line. The ball bearings can guide the cutting device as it rotates. The sliding rod moves to one side through the threaded rod to adjust the distance between the fixed plate and the limiting plate, which can position and guide the cutting device. The support rod moves with the limiting plate and supports the limiting plate. The sliding rod and the support rod slide within the fixed plate through sliders on both sides, which can improve the stability of the sliding rod and the support rod during movement. By observing the position of the water bubble in the bubble tube for reference, the fixed plate and the limiting plate can be placed stably, and the concrete joint cutting can be positioned to prevent deviation during the cutting process. 2. When using the fixing plate, after calibrating its position, the fixing plate can hold multiple counterweights through multiple L-shaped fixing blocks to fix its position. Two fixing rods pass through multiple counterweights in sequence to limit their movement. Then, with the cooperation of nuts, the counterweights can be fixed on the fixing blocks. This can fix the position of the fixing plate and the limiting plate to prevent displacement when cutting concrete joints. Attached Figure Description

[0019] The following is combined with Figure 1 - Figure 5 This invention describes a device for precise positioning of concrete cut joints in airport pavements.

[0020] In one embodiment, a device for precise positioning of concrete cut joints on airport pavement includes a fixed plate 100, with a limiting plate 200 on one side of the fixed plate 100; a positioning mechanism 300, which can position the concrete cut joint and maintain vertical cutting, is disposed on one side of the fixed plate 100; wherein, the positioning mechanism 300 includes a sliding rod 310 fixedly connected to one side of the limiting plate 200, the other end of the sliding rod 310 being slidably connected to the inner wall of the fixed plate 100, a threaded rod 320 being rotatably connected to one end of the inner wall of the fixed plate 100, one end of the threaded rod 320 being threadedly connected to the inner wall of the sliding rod 310, a plurality of evenly arranged ball bearings 330 being rotatably connected to both one side of the fixed plate 100 and the limiting plate 200, and a fixing component 370 being disposed on the other side of the fixed plate 100.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 300 also includes a bubble tube 340 fixedly connected to the top ends of the fixed plate 100 and the limiting plate 200. The bubble tube 340 is horizontally installed on the top of the fixed plate 100 and the limiting plate 200. A support rod 350 is fixedly connected to one side of the limiting plate 200. The support rod 350 is located on one side of the sliding rod 310. One end of the support rod 350 is slidably connected to the inner wall of the fixed plate 100. Slider 360s are fixedly connected to both sides of the sliding rod 310 and the support rod 350. The slider 360s are engaged with the two ends of the inner wall of the fixed plate 100.

[0022] In this embodiment, the fixed plate 100 and the limiting plate 200 cooperate to position the cutting device. Rotating the threaded rod 320 and the sliding rod 310 threadedly connects to drive the limiting plate 200 to slide open to one side. The support rod 350 slides within the fixed plate 100 along with the limiting plate 200, which can support the other end of the limiting plate 200. The sliding rod 310 and the support rod 350 can improve the stability of the limiting plate 200 when it moves through the sliders 360 on both sides. Multiple ball bearings 330 on one side of the fixed plate 100 and the limiting plate 200 contact the two sides of the cutting device, which can position and guide the cutting device. By observing the bubble tube 340, the fixed plate 100 and the limiting plate 200 can be placed stably on the airport runway, which can position and guide the concrete cut and prevent the concrete cut from deviating.

[0023] like Figure 5 As shown, the fixing component 370 includes several fixing blocks 371 that are evenly arranged and fixedly connected to the other side of the fixing plate 100. Several counterweights 372 that are evenly arranged are provided on the other side of the fixing blocks 371. Two fixing rods 373 are fixedly connected to the top of the other side of the fixing blocks 371. One end of the fixing rods 373 passes through several counterweights 372 in sequence. The top of the fixing rods 373 is threadedly connected to a nut 374, which is located at the top of the counterweights 372.

[0024] In this embodiment, multiple counterweights 372 placed on the other side of multiple fixing blocks 371 can fix the fixing plate 100 to prevent the fixing plate 100 from shifting during use. Two fixing rods 373 on the fixing block 371 can limit the placement of the counterweight 372. The fixing rods 373 can then cooperate with the nuts 374 to fix the counterweight 372, thereby fixing the position of the fixing plate 100 and the limiting plate 200 to prevent the concrete cut from shifting.

[0025] Working principle: First, the position of the fixed plate 100 is vertically calibrated. Then, multiple counterweights 372 are placed on the fixed block 371. The fixed block 371 is fixed by two fixed rods 373 passing through the multiple counterweights 372 in sequence. The nut 374 is manually rotated and threaded to the fixed rod 373 to move downward and fix the counterweights 372. The threaded rod 320 is manually rotated and threaded to the sliding rod 310, so that the sliding rod 310 drives the limiting plate 200 to move to one side. When the limiting plate 200 moves to one side, the support rod 350 slides to one side as well. The width of the cutting device is adjusted according to the width of the cutting device. The ball bearings 330 on one side of the fixed plate 100 and the limiting plate 200 contact the two sides of the cutting device, which can limit and guide the cutting device.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
