Description

Technical Field

[0001] This utility model relates to the field of road construction measurement technology, specifically a measuring device for the loose thickness of asphalt concrete pavement. Background Technology

[0002] In the construction of asphalt concrete pavements, loose paving thickness is one of the key parameters determining the final quality of the pavement. Appropriate loose paving thickness ensures that the pavement achieves ideal smoothness, strength, and durability after compaction. With the continuous development of road construction technology and the increasing sophistication of construction standards, higher demands are placed on the accuracy, convenience, and efficiency of measuring the loose paving thickness of asphalt concrete pavements.

[0003] Currently, most traditional asphalt concrete pavement loose-pavement thickness measuring devices use a simple steel rod insertion method. In practice, due to the lack of precise scale markings and guiding structures, it is difficult for measuring personnel to accurately judge the depth and verticality of the steel rod insertion, resulting in large measurement errors and failing to meet the accuracy requirements of modern high-standard pavement construction. Therefore, we propose a new device for measuring the loose-pavement thickness of asphalt concrete pavement. Utility Model Content

[0004] The main objective of this invention is to provide a measuring device for the loose thickness of asphalt concrete pavement, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a measuring device for loose asphalt concrete pavement thickness, comprising a chassis, a scale column threadedly connected to the top of the chassis, a guide slide fixedly connected to the top of the chassis, a plug rod slidably connected to the inner wall of the chassis, a connecting seat fixedly connected to the top of the plug rod, an arrow plate fixedly connected to the side wall of the connecting seat, a connecting rod fixedly connected to the end of the connecting seat away from the arrow plate, a guide slider detachably connected to the end of the connecting rod away from the arrow plate, and a foot plate fixedly connected to the top of the connecting seat.

[0006] Preferably, the outer wall of the guide slider is slidably connected to the inner wall of the guide slide block.

[0007] Preferably, the guide slide has an adjustment hole, and the inner wall of the adjustment hole is threaded with an adjustment screw.

[0008] Preferably, the guide slider has a stepped through hole.

[0009] Preferably, a lifting rod is threadedly connected to the top of the chassis, and a handrail is fixedly connected to the top of the lifting rod.

[0010] Preferably, the side wall of the chassis is threaded with a horizontal bar.

[0011] Preferably, four sets of horizontal bars are provided.

[0012] This utility model provides a measuring device for the loose thickness of asphalt concrete pavement. It has the following features:

[0013] Beneficial effects:

[0014] (1) The measuring device for loose asphalt concrete pavement thickness achieves stable guidance and flexible positioning during the measurement process through a structure including a guide slide, a guide slider, and an adjusting screw. The high-precision fit between the guide slide and the guide slider ensures that the insertion rod is inserted vertically into the pavement, avoiding measurement deviations caused by tilting. The design of the adjusting screw and the step through hole allows for flexible limitation of the guide slider's movement range according to actual needs, ensuring the stability of the measurement data.

[0015] (2) In order to avoid large displacement of the plug rod, the measuring device for loose asphalt concrete pavement thickness rotates the adjusting screw to make it slide into the step through hole of the guide slider, thereby preventing large displacement of the guide slider. The connecting rod restricts the movement of the plug rod. At the same time, the horizontal bar can be stored, which effectively reduces the space occupied by the equipment when it is idle, facilitates transportation and storage, and improves the practicality and convenience of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figures 1-4 This utility model proposes a measuring device for the loose thickness of asphalt concrete pavement, including a chassis 1. A scale post 2 is threadedly connected to the top of the chassis 1, and scale lines are provided on the scale post 2. A guide slide 3 is fixedly connected to the top of the chassis 1. A connector rod 4 is slidably connected to the inner wall of the chassis 1. The bottom of the connector rod 4 is conical, and a connecting seat 5 is fixedly connected to the top of the connector rod 4. An arrow plate 6 is fixedly connected to the side wall of the connecting seat 5, with the arrow pointing towards the scale line for easy observation of the displacement of the connector rod 4. When the arrow plate 6 points to the 0 mark, the bottom of the plug rod 4 is flush with the bottom of the chassis 1. When the arrow plate 6 points to the 10 mark, it indicates that the plug rod 4 has moved 10 cm. The end of the connecting seat 5 away from the arrow plate 6 is fixedly connected to the connecting rod 7. The end of the connecting rod 7 away from the arrow plate 6 is detachably connected to the guide slider 8. The connecting rod 7 and the guide slider 8 are detachably connected by screws. The top of the connecting seat 5 is fixedly connected to the foot plate 9, which allows the staff to step on it with their feet, thereby inserting the plug rod 4 into the road surface.

[0025] In this utility model, the outer wall of the guide slider 8 is slidably connected to the inner wall of the guide slide block 3. The guide slide block 3 is provided with a guide groove, and the outer wall of the guide slider 8 is slidably connected to the inner wall of the guide groove. The guide groove guides the movement of the guide slider 8, and the connecting rod 7 guides the displacement of the plug rod 4.

[0026] Furthermore, the guide slide 3 is provided with an adjustment hole 10, and the inner wall of the adjustment hole 10 is threaded with an adjustment screw 11. The guide slide is interconnected with the adjustment hole 10, and rotating the adjustment screw 11 can make it be placed in the guide slide.

[0027] Furthermore, the guide slider 8 is provided with a stepped through hole 12. The adjusting screw 11 can slide into the larger hole in the stepped through hole 12. When the adjusting screw 11 is in the stepped through hole 12, the guide slider 8 can be prevented from moving too much in the guide groove, thereby preventing the plug rod 4 from moving too much.

[0028] Furthermore, a lifting rod 13 is threadedly connected to the top of the chassis 1, and a handrail 14 is fixedly connected to the top of the lifting rod 13. The lifting rod 13 and the handrail 14 form a set, and there are two sets in total. They are symmetrically distributed on the chassis 1, and the handrail 14 makes it convenient for the staff to hold the handle.

[0029] Furthermore, a horizontal rod 15 is threadedly connected to the side wall of the chassis 1, and a connection hole is provided on the side wall of the chassis 1. Four sets of connection holes are provided, and the horizontal rod 15 is threadedly connected to the inner wall of the connection hole.

[0030] Furthermore, four sets of horizontal rods 15 are provided, and storage holes are also provided on the top of the chassis 1. Four sets of storage holes are provided, and the horizontal rods 15 can also be threaded into the storage holes. By completing the threaded connection between the horizontal rods 15 and the storage holes, the horizontal rods 15 can be changed from a horizontal state to a vertical state, reducing the space occupied and facilitating storage.

[0031] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0032] When using the device, place it on the asphalt concrete pavement to be measured and hold the handle 14 to keep the chassis 1 stable. Insert the connector 4 vertically into the pavement by stepping on the foot pedal 9. During insertion, observe the corresponding position of the arrow plate 6 and the scale line on the scale post 2. After the connector 4 is inserted stably, read the scale indicated by the arrow plate 6 to obtain the loose pavement thickness data.

[0033] After the measurement is completed, the horizontal rod 15 is unscrewed from the connecting hole and then screwed into the storage hole to make the horizontal rod 15 stand vertically, reducing the space occupied by the equipment and making it easier to transport and store. At the same time, in order to prevent the plug rod 4 from moving too much, the adjusting screw 11 is rotated to make it slide into the stepped through hole 12 of the guide slider 8, thereby preventing the guide slider 8 from moving too much. This, together with the connecting rod 7, restricts the movement of the plug rod 4.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
