Description

Technical Field

[0001] This utility model relates to the technical field of tools for highway surveying, and more specifically, to a scraper for route construction layout in highway surveying and design. Background Technology

[0002] In highway surveying, design, construction, and layout, the geometric relationship between the characteristic points and control points of each part of the building is usually determined based on the design dimensions of the building. Layout data such as distance, angle, elevation, and coordinates are calculated. Then, the characteristic points of the building are determined on the ground using the control points, and construction is carried out accordingly.

[0003] Patent CN222375150U discloses a road surface leveling scraper for highway surveying and design. It allows workers to level the road surface while standing, eliminating the need to squat, by using a handheld lever and a first and second clamping plate. The structure of an adjusting sleeve and a sliding sleeve allows the first and second clamping plates to be tightened or loosened by rotating the adjusting sleeve, enabling quick scraper replacement. However, while the scraper can be tightened or loosened, the clamping components only maintain parallelism for scrapers of a specific thickness. For scrapers of other thicknesses, they cannot maintain parallelism, thus failing to effectively contact and hold the scraper. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figures 1-3 As shown, this embodiment provides a scraper for road surveying and design, including an adjustable limiting component and an adjustable clamping plate component. The adjustable clamping plate component, used to clamp the scraper 1, includes an upper clamping plate 2 and a lower clamping plate 3. An elastic component 4 is arranged between the upper clamping plate 2 and the lower clamping plate 3, which is used to adjust the distance between the upper clamping plate 2 and the lower clamping plate 3, thereby adaptably clamping scrapers 1 of different thicknesses. The adjustable limiting component is used to clamp and limit the adjustable clamping plate component. The adjustable limiting component includes a bottom plate 5 abutting against the lower clamping plate 3 and a top plate 7 sliding up and down along a connecting plate 6. An adjustable support component is arranged between the bottom plate 5 and the top plate 7. An adjusting sleeve 8 is fixedly connected to the outside of the connecting plate 6, and the adjusting sleeve 8 is used to detachably connect a hand-held rod, allowing construction personnel to hold the hand-held rod for operation.

[0040] In the adjustable clamp assembly of this embodiment, such as Figures 1-4 As shown, the lower clamping plate 3 is a flat plate structure, with a lower locking tooth 31 fixedly connected to its upper end face; a limiting strip 32 is also provided on the upper end face of the lower clamping plate to prevent the scraper from detaching from both sides of the adjustable clamping plate assembly. The upper clamping plate 2 is a flat plate structure, with an upper locking tooth 21 that matches the lower locking tooth 31 fixedly connected to its lower end face.

[0041] An elastic component 4 is also provided between the upper clamping plate 2 and the lower clamping plate 3, and at least one set of the elastic component 4 is provided. In this embodiment, two sets of elastic components are provided, symmetrically arranged with the central axis of the lower clamping plate as the axis.

[0042] Specifically, such as Figures 2-4As shown, the elastic component 4 includes a lower sleeve 41 fixed to the upper end face of the lower clamping plate 3 and an upper sleeve 42 fixed to the lower end face of the upper clamping plate 2. The upper sleeve 42 is sleeved outside the lower sleeve 41, and the two can slide relative to each other up and down. The elastic component 4 also includes a spring 43 located inside the upper sleeve 42 and the lower sleeve 41. The top end of the spring 43 is fixed to the lower end face of the upper clamping plate 2, and the bottom end is fixed to the upper end face of the lower clamping plate 3. By moving the upper clamping plate 2 or the lower clamping plate 3, or by moving the upper clamping plate 2 and the lower clamping plate 3 simultaneously, the two are moved away from each other, which stretches the spring 43 between them. Then, the scraper 1 is inserted, and the upper clamping plate 2 or the lower clamping plate 3 is released, so that the upper clamping plate 2 and the lower clamping plate 3 clamp the scraper 1 under the elastic force of the spring returning to its original position. Then, the adjustable limiting component is used to limit the upper clamping plate 2 and the lower clamping plate 3 to achieve stable clamping of the scraper 1, so as to carry out the line construction layout operation. In practical applications, when the upper clamping tooth 21 of the upper clamping plate 2 and the lower clamping tooth 31 of the lower clamping plate 3 are engaged, the distance between the upper clamping plate 2 and the lower clamping plate 3 can clamp the thinnest scraper. When the thickness of the scraper used increases, it can be adaptively clamped according to the adjustment function of the elastic component 4 and the mutual distance between the upper clamping tooth 21 and the lower clamping tooth 31.

[0043] In the adjustable limiting assembly of this embodiment, the base plate 5 is fixed to the bottom of the connecting plate 6. The base plate 5 has a flat plate structure, and two symmetrically arranged L-shaped plates 61 are provided on the inner side wall of the connecting plate 6. The two L-shaped plates 61 respectively form a sliding groove 62 with the inner side wall of the connecting plate 6, and the opening directions of the two sliding grooves 62 are opposite to each other. The top plate 7 can move up and down along the sliding groove 62. The top plate 7 has a flat plate structure, and a sliding plate 71 is connected to one end of the top plate 7. The sliding plate 71 moves up and down along the sliding groove 62, thereby forming a top plate 7 and a base plate 5 with different spacing.

[0044] In this embodiment, the adjustable support assembly includes a base 9 and a threaded cylinder 10 that are threaded together, and a screw 11 that passes through the base 9 and the threaded cylinder 10. The two ends of the screw 11 extend below the base plate 5 and above the top plate 7, and are fastened with nuts 12.

[0045] More specifically, the top plate 7 has a first upper through hole 72, and the bottom plate 5 has a first lower through hole 51. The screw 11 passes through the first upper through hole 72 and the first lower through hole 51 respectively. Correspondingly, the upper clamping plate 2 has a second upper through hole 22, and the lower clamping plate 3 has a second lower through hole 33. The second upper through hole 22, the second lower through hole 33, the first upper through hole 72, and the first lower through hole 51 overlap vertically. The screw 11 passes through the second upper through hole 22, the second lower through hole 33, the first upper through hole 72, and the first lower through hole 51 respectively, and bolts are screwed on both ends. The bolts abut against the upper end face of the top plate 7 and the lower end face of the bottom plate 5 respectively, so as to realize the fastening and limiting of the adjustable clamping plate assembly by the adjustable limiting assembly. The threaded cylinder 10 is threadedly connected to the base support 9. By adjusting the relative position of the threaded cylinder 10 and the base support 9, the distance between the top plate 7 and the bottom plate 5 can be adaptively adjusted so that the height of the structure composed of the base 9 and the threaded cylinder 10 is equal to the overall thickness of the adjustable clamping plate assembly after the scraper 1 is clamped. The structure composed of the base 9 and the threaded cylinder 10 supports the top plate 7 and the bottom plate 5, thereby achieving the stability of the overall structure.

[0046] In this embodiment, the adjustable support component and the elastic component 4 are located on both sides of the upper and lower locking teeth, respectively, and the adjustment of the adjustable support component and the elastic component 4 does not interfere with each other.

[0047] The road survey and design route layout scraper provided in this embodiment involves moving the upper clamping plate 2 or the lower clamping plate 3, or simultaneously moving both, to separate them and stretch the spring 43 between them. Then, the scraper 1 is inserted, and the upper clamping plate 2 or the lower clamping plate 3 is released, allowing the upper and lower clamping plates 2 and 3 to clamp the scraper 1 under the spring's return force. The adjustable clamping plate assembly holding the scraper 1 is then placed on the base plate 5 of the adjustable limiting assembly. The relative positions of the base 9 and the threaded cylinder 10 are adjusted so that the overall height of the base 9 and the threaded cylinder 10 is the same as the overall height of the adjustable clamping plate assembly holding the scraper 1. Then, the screw 11 is passed through from bottom to top to... Rod 11 passes sequentially through the first lower through hole 51 of the base plate 5, the second lower through hole 33 of the lower clamping plate 3, the base 9, the threaded cylinder 10, and the first upper through hole 72 of the upper clamping plate 2. At the same time, a nut is threaded onto the bottom end of the rod 11, so that the nut abuts against the lower end face of the base plate 5. Then, the top plate 7 slides down along the slide groove 62 until it abuts against the upper end face of the upper clamping plate 2, and the top end of the rod 11 passes through the second upper through hole 22 of the upper clamping plate 2. Another nut is screwed into the top end of the rod 11, so that the nut abuts against the upper end face of the top plate 7. This achieves the limitation of the upper clamping plate 2 and the lower clamping plate 3 by using the adjustable limiting component, thereby achieving stable clamping of the scraper 1 and facilitating the layout operation of the line construction.

[0048] The road surveying and design route layout scraper provided in this embodiment uses an upper clamping plate 2 and a lower clamping plate 3 for holding the scraper 1. Under the adjustment of the elastic component 4, these plates remain parallel to the scraper 1, allowing for adaptive and secure clamping of scraper 1 of different thicknesses. The elastic component facilitates the secure clamping of scraper 1 of different thicknesses, and the adjustable limiting component further secures the adjustable clamping plate assembly holding the scraper 1, maintaining the overall stability of the structure during operation.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
