Description

Technical Field

[0001] The utility model belongs to the technical field of construction laying-out, in particular to a laying-out device for asphalt pavement construction. Background Art

[0002] Construction layout is one of the basic skills of construction management personnel. Construction positioning layout is related to the success or failure of the entire project. The purpose of construction layout is to ensure that the construction project is carried out safely and smoothly in accordance with the requirements of planning approval through prior inspection of the positioning layout of the construction project, while taking into account the improvement of municipal facilities and environmental quality, and avoiding infringement on the interests of adjacent property rights. During the construction of the pavement structure layer, it is necessary to lay out the edge of the pavement and determine the position of the pavement structure layer. When the paver is paving, the edge position and elevation control are carried out according to the layout position. Therefore, it is necessary to set a baseline, and the baseline can be quickly fixed and adjusted during the layout and elevation measurement process to ensure construction quality and efficiency.

[0003] A Chinese patent discloses a device for fixing the edge of a road surface for construction (publication number CN216193840U). The patent determines the construction position of the edge of the road surface by a fixing rod, and uses a fixing frame to quickly determine the position and height of the reference wire rope, so as to control the linearity and elevation of the construction of the road surface structure layer, ensure the straightness of the edge linearity of the road surface structure layer, and verify the design requirements for the position and elevation to ensure the construction quality. However, the patent cannot adjust the distance between the fixing rod and the road surface at will during use. The fixing rod needs to be manually pulled out and inserted during adjustment, which will not only cause the displacement of the fixing rod, but also cause deviation in the laying out of the line, affecting the accuracy of the laying out of the line, and the reference line is not protected and dustproofed to prevent the risk of damage and breakage of the reference line and reduce the adhesion of dust.

[0024] Example 1: Figure 1-4 As shown, the utility model aims to provide a laying-out device for asphalt pavement construction, so as to solve the problems in the prior art that the laying-out requirements for roads of different widths cannot be adapted and the reference line is not protected. According to the above functions, the whole device includes a base 1, a counterweight 5 is provided at the top of the base 1, and the counterweight 5 plays a role in adjusting the center of gravity to prevent the device from tipping over. A support plate 2 is provided on the periphery of the counterweight 5, one end of the support plate 2 is fixedly connected to the base 1, and a storage bin 6 is fixedly installed on the side of the other end of the support plate 2. A mutually interpenetrating storage groove is provided between the storage bin 6 and the support plate 2. The size of the storage groove is larger than the size of the take-up wheel 7, so that the take-up wheel 7 can be wrapped, and then the take-up wheel 7 can be stored, which plays a role in saving space and preventing dust. A take-up wheel 7 is provided on the side of the storage bin 6, and the inner cavity of the take-up wheel 7 is provided with a conveying mechanism for facilitating the storage of the take-up wheel 7. A laying-out mechanism is provided on the side of the take-up wheel 7. Threaded drill rods 4 are provided on both sides of the base 1.

[0025] The conveying mechanism includes a threaded support rod 18 fixedly sleeved in the inner cavity of the storage bin 6, and a threaded barrel 11 is threadedly sleeved at one end of the threaded support rod 18 away from the storage bin 6. A threaded groove is provided in the inner cavity of the threaded barrel 11 to match the threaded support rod 18. The threaded barrel 11 realizes threaded rotation on the periphery of the threaded support rod 18 through the threaded groove. A plurality of sliding rods 19 are slidably sleeved in the side inner cavity of the threaded barrel 11. The sliding rod 19 can play the role of connecting support. When the threaded barrel 11 rotates, the sliding rod 19 can be opened on the side of the threaded barrel 11. A connecting rod 13 is fixedly connected to one end of the threaded barrel 11 away from the threaded support rod 18. A rocker 10 is provided on the side of the connecting rod 13 to facilitate driving the threaded barrel 11 to rotate. The threaded rotation of the threaded barrel 11 can be realized by shaking the rocker 10.

[0026] like Figure 3As shown, the conveying mechanism also includes a first limit block 20 fixedly connected to one end of the sliding rod 19, the first limit block 20 is rotatably sleeved on one side of the inner cavity of the storage bin 6, a circular groove is provided in the inner cavity of the storage bin 6, the first limit block 20 is rotatably sleeved in the inner cavity of the circular groove, the other end of the sliding rod 19 is fixedly connected to a second limit block 21, the second limit block 21 is slidably sleeved in the side inner cavity of the threaded barrel 11, a sliding groove is provided on the side of the threaded barrel 11, when the threaded barrel 11 is threadedly rotated, the second limit block 21 and the sliding rod 19 are driven to move spirally in the inner cavity of the sliding groove, and the size of the sliding groove is matched with the size of the second limit block 21.

[0027] like Figure 2 As shown, a connecting plate 14 is fixedly sleeved on the outer periphery of one end of the connecting rod 13 away from the threaded tube 11, and one end of the connecting plate 14 away from the connecting rod 13 is fixedly sleeved on one end of the rocking arm 10. Specifically, since the connecting rod 13 and the two sides of the rotating sleeve 8 are rotatably sleeved with each other, when the rocking arm 10 is shaken, the connecting plate 14 and the connecting rod 13 can be driven to rotate without affecting the rotating sleeve 8 and causing the rotating sleeve 8 to rotate synchronously.

[0028] Example 2: Figure 2-3 As shown, the line-releasing mechanism includes a rotating shell 8, a plurality of rudder poles 9 are fixedly connected to the periphery of the rotating shell 8, a turntable 15 is fixedly sleeved in the inner cavity of the rotating shell 8, a plurality of fixed rods 16 are fixedly connected to the side of the turntable 15, and one end of the fixed rod 16 away from the turntable 15 is fixedly connected to one side of the take-up wheel 7. Specifically, when the rudder pole 9 is rotated, the rotating shell 8 can be driven to rotate, and the turntable 15 and the fixed rod 16 can be driven to rotate, thereby driving the take-up wheel 7 to complete the line-reeling and line-releasing work.

[0029] like Figure 2 As shown, a rotating groove 17 is opened on the side of the rotating housing 8 , and the size of the rotating groove 17 is adapted to the size of the fixing rod 16 . When the fixing rod 16 rotates driven by the rotating disk 15 , it can rotate in the inner cavity of the rotating groove 17 .

[0030] like Figure 2 As shown, both ends of the take-up wheel 7 are provided with a limit ring 12, and the limit ring 12 is fixedly sleeved on the two ends of the threaded tube 11. By fixing the limit ring 12 on the two ends of the threaded tube 11, the take-up wheel 7 can be limited to prevent the take-up wheel 7 from moving around the periphery of the threaded tube 11 and prevent the deviation of the line release. The threaded tube 11 and the take-up wheel 7 are rotatably sleeved with each other.

[0031] like Figure 4As shown, a cross slot 24 is provided at the top of the base 1, and a cross block 23 is slidably sleeved in the inner cavity of the cross slot 24. The top of the cross block 23 is fixedly connected to the bottom of the counterweight 5. When in use, the cross block 23 is pushed to drive the counterweight 5 to move, thereby playing a role in adjusting the center of gravity of the device. A leakage hole 25 is provided at the bottom of the cross slot 24. The leakage hole 25 is convenient for draining rainwater accumulated in the inner cavity of the cross slot 24 out of the inner cavity of the base 1. The opposite sides of the base 1 are fixedly connected with support blocks 22, and the side portions of the support blocks 22 are threadedly rotatably sleeved with the periphery of the threaded drill rod 4. A plurality of support legs 3 are fixedly installed at the bottom of the base 1. Specifically, the support legs 3 are leg components composed of a rotating wheel, a rotating rod and a mounting seat. The rotating wheel is rotatably connected to the mounting seat through the rotating rod, and the device can be moved by moving the rotating wheel.

[0032] The working principle of the utility model is:

[0033] When the device needs to be used, the support leg 3 can be used to move the device, and the threaded drill rod 4 can be rotated so that one end of the threaded drill rod 4 can be drilled into the construction road surface, so that the device can be fixed in an appropriate position, thereby increasing the stability of the device and preventing the device from tipping over. The connecting plate 14 and the connecting rod 13 can be driven to rotate by shaking the rocker 10. The rotation of the connecting rod 13 can drive the threaded cylinder 11 to rotate on the periphery of the threaded support rod 18. When the threaded cylinder 11 rotates, the wire take-up wheel 7 can be driven to move spirally, and at this time, the sliding rod 19 and the second limit block 21 slide in the side inner cavity of the threaded cylinder 11. When the inner cavity of the threaded cylinder 11 and the outer periphery of one end of the threaded support rod 18 away from the storage bin 6 abut against each other, the wire take-up wheel 7 is also on both sides. Under the limiting action of the limiting ring 12, it moves to the inner cavity of the storage bin 6, thereby completing the storage of the take-up wheel. If the above operation is performed in reverse, the take-up wheel 7 can be driven to move out of the inner cavity of the storage bin 6, and according to the width of the asphalt pavement, the take-up wheel 7 can be adjusted to a height line perpendicular to the shoulder, thereby ensuring that the released line can be maintained at different vertical heights of the same horizontal line as the shoulder. By rotating the rudder bar 9, the rotating sleeve 8 can be driven to rotate, and the rotation of the rotating sleeve 8 can drive the turntable 15 and the fixed rod 16 to rotate. Since the fixed rod 16 is fixedly connected to the side of the take-up wheel 7, and the take-up wheel 7 and the threaded barrel 11 are rotatably sleeved with each other, the rotation of the fixed rod 16 can drive the take-up wheel 7 to rotate, thereby completing the work of releasing and taking up the reference line;

[0034] At the same time, the position of the counterweight 5 in the inner cavity of the base 1 can be adjusted according to the distance between the take-up wheel 7 and the threaded barrel 11 and the storage bin 6, so as to adapt to the situation where the center of gravity of the device is shifted when the take-up wheel 7 and the threaded barrel 11 move, thereby ensuring the stability of the device during use.

[0035] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0036] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
