Description

Technical Field

[0001] This utility model relates to the field of construction technology, and in particular to a device for testing the compaction degree of on-site backfill roadbed. Background Technology

[0002] The on-site subgrade compaction testing device is used to evaluate the quality of subgrade filling projects. Its function is to measure the compaction degree of the subgrade filling during construction. An existing on-site subgrade compaction testing device for highway engineering (Announcement No.: CN216515497U) has revealed at least the following defects in use:

[0003] Because the device requires not only an electric hydraulic rod to press down for detection, but also a bidirectional hydraulic rod to push the anti-slip teeth down and support the device, it uses a lot of energy-intensive equipment, which increases the cost of using the device. Utility Model Content

[0004] The purpose of this utility model is to address the problem that existing on-site testing devices for roadbed compaction in highway engineering require two drive sources—an electric hydraulic rod and a bidirectional hydraulic rod—to measure the compaction of fill roadbeds, resulting in excessive energy consumption and increased costs. This invention provides a new on-site testing device for fill roadbed compaction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The detection component includes a detection component, a driving component, and a moving component. The detection component is connected to the driving component through the moving component. The detection component is used to detect the compaction degree of the fill subgrade. The driving component is used to drive the moving component to lift and lower the detection component.

[0008] The linkage component includes a transmission component and an anti-slip component. The anti-slip component is connected to the transmission component, and the transmission component is connected to the moving component. When the moving component descends, it can drive the anti-slip component to lower. When the moving component rises, it can drive the anti-slip component to retract.

[0009] The on-site soil compaction testing device of this utility model uses a driving component to sequentially lower the moving component and the testing component, enabling the testing component to perform testing operations. Simultaneously, the moving component lowers, and the transmission component drives the anti-slip component to descend for support. This device requires only one drive source to achieve the lifting and lowering of both the testing component and the anti-slip component. It uses minimal energy-consuming equipment, reducing the cost of the device. The device has a simple structure, is easy to use, and performs well.

[0019] The left-hand thread and the right-hand thread of the bidirectional lead screw are respectively threaded to one of the moving blocks;

[0020] The anti-slip component includes an anti-slip toothed plate, and the two ends of the rotating rod are respectively hinged to the anti-slip toothed plate and a moving block. The two rotating rods are set in opposite inclination directions.

[0021] As a further preferred technical solution of this utility model, the bottom of the movable block is provided with a first rotating seat, the top of the anti-slip toothed plate is provided with a second rotating seat, and the two ends of the rotating rod are respectively rotatably connected to the first rotating seat and the second rotating seat.

[0022] As a further preferred technical solution of this utility model, the support plate is a frame structure, and a linkage groove is provided on each side of the support plate. The detection component is located in the hollow part in the middle of the support plate.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0034] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0035] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0036] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0037] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0038] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0039] In this invention, the electrical components are controlled by an external controller that is paired with them. The control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field and is used without modification. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0040] In related technologies, a testing device is required during the on-site compaction testing of fill roadbeds. Existing on-site roadbed compaction testing devices require two drive sources—an electric hydraulic rod and a bidirectional hydraulic rod—to measure the density of fill roadbeds, resulting in significant energy consumption and increased costs. Therefore, this application provides a field fill roadbed compaction testing device specifically designed for on-site fill roadbed compaction testing. The following details the device... Figures 1 to 5 To elaborate.

[0041] Example 1

[0042] like Figures 1 to 5 As shown, the on-site soil filling roadbed compaction testing device of this utility model includes a bearing plate 1, on which a moving wheel 2, a push handle 3, a mounting frame 5, a testing component 6 and a linkage component 7 are provided.

[0043] like Figures 1 to 3As shown, the support plate 1 is a frame structure, specifically a rectangular frame welded from square steel. A linkage groove 4 is provided on each of the two sides of the bottom of the support plate 1. A mounting bracket 5 is provided on each of the two sides of the top of the support plate 1. The mounting bracket 5 can be a portal frame welded from square steel. The illustration shows the mounting bracket 5 located in the middle of the side of the support plate 1. The mounting bracket 5 can also be installed in other positions on the side of the support plate 1, but the two mounting brackets 5 need to be symmetrically arranged so that the detection component 6 can be laterally connected to the two mounting brackets 5. In one specific embodiment, the support plate 1 corresponding to the bottom of the portal frame has an opening.

[0044] The detection component 6 includes a first support 601, a detection component, a driving component, and a moving component. The detection component is connected to the driving component through the moving component. The detection component is used to detect the compaction degree of the fill subgrade. The driving component is used to drive the moving component to lift and lower the detection component.

[0045] like Figure 1 and Figure 4 As shown, the first bracket 601 is arranged laterally relative to the bearing plate 1, and both ends of the first bracket 601 are respectively connected to the tops of the two mounting brackets 5. The first bracket 601 can be beam-shaped or gate-shaped. The driving component includes a linear reciprocating motion structure, which is installed on the top of the first bracket 601. The output end of the linear reciprocating motion structure passes through the first bracket 601 and can move up and down. The moving component includes a second bracket, the top of which is connected to the output end of the linear reciprocating motion structure, the bottom of which is connected to the detection component, and the side of which is connected to the transmission component. The detection component is located in the hollow part in the middle of the bearing plate 1. The detection component includes a pressure gauge 604 and a compression cylinder 605. The pressure gauge 604 is connected to the bottom of the second bracket, and the compression cylinder 605 is connected to the bottom of the pressure gauge 604.

[0046] In some specific embodiments, the linear reciprocating motion structure is an electro-hydraulic rod 602, an electro-pneumatic rod, a crank-slider mechanism, a gear and rack mechanism, or a lead screw and nut mechanism.

[0047] When the electric hydraulic rod 602 or the electric pneumatic rod is used, its output rod portion passes through the first bracket 601 and is directly connected to the moving component.

[0048] When the crank-slider mechanism is used, the crank-slider mechanism includes a motor, a crank structure, a slider, and a linear guide rail. The linear guide rail is vertically arranged, and the slider is slidably connected to the linear guide rail. The slider's movement path passes through the first bracket 601. The slider is connected to the moving component. The motor drives the crank structure to rotate, and the crank structure rotates to connect the slider, driving the slider to reciprocate along the linear guide rail, thereby realizing the lifting and lowering of the moving component.

[0049] When the gear and rack mechanism is used, the gear and rack mechanism includes a motor, a gear, a rack and a linear guide groove. The linear guide groove is vertically arranged, and the rack is slidably connected in the linear guide groove. The movement path of the rack passes through the first bracket 601. The rack is connected to the moving component. The rack meshes with the gear. The motor drives the gear to rotate in both forward and reverse directions, thereby driving the gear to move up and down, realizing the lifting and lowering of the moving component.

[0050] When the lead screw and nut mechanism is used, the lead screw and nut mechanism includes a motor, a lead screw and a nut. The nut is threadedly connected to the lead screw. The lead screw is vertically arranged. The moving path of the nut passes through the first bracket 601. The nut is connected to the moving component. The motor drives the lead screw to rotate in both forward and reverse directions, thereby driving the nut to move up and down, realizing the lifting and lowering of the moving component.

[0051] In some specific embodiments, the second bracket includes a T-shaped plate 603 or a cross plate.

[0052] In this embodiment, as Figure 1 and Figure 4 As shown, the linear reciprocating motion structure adopts the electro-hydraulic rod 602, and the second support adopts the T-shaped plate 603. The T-shaped plate 603 is inverted, and its vertical rod is connected to the output rod of the electro-hydraulic rod 602. The horizontal rod of the T-shaped plate 603 is located at its bottom and is arranged parallel to the first support 601. The two ends of the horizontal rod are respectively provided with linkage racks 607. The bottom of the horizontal rod is connected in sequence to the pressure gauge 604 and the extrusion cylinder 605. The extrusion cylinder 605 is provided with a scale bar 606.

[0053] As the T-shaped plate 603 moves downward, it sequentially drives the pressure gauge 604 and the extrusion cylinder 605 downward. While the extrusion cylinder 605 extrudes the on-site backfill subgrade to be tested, the scale bar 606 can display the depth of the extrusion cylinder 605 entering the on-site backfill subgrade, and the pressure gauge 604 will display the pressure of the on-site backfill subgrade on the extrusion cylinder 605 at this time.

[0054] When the extrusion cylinder 605 travels to a fixed depth, a higher pressure displayed by the pressure gauge 604 indicates a higher compaction degree of the on-site earthwork subgrade, while a lower pressure displayed by the pressure gauge 604 indicates a lower compaction degree of the on-site earthwork subgrade.

[0055] The linkage component 7 includes a transmission component and an anti-slip component. The anti-slip component is connected to the transmission component, and the transmission component is connected to the moving component. When the moving component descends, it can drive the anti-slip component to descend. When the moving component rises, it can drive the anti-slip component to retract.

[0056] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the transmission component includes a bidirectional lead screw 701 and two rotating rods 705. The two ends of the bidirectional lead screw 701 are rotatably connected to the linkage groove 4. The bidirectional lead screw 701 is provided with a linkage gear 702 and two moving blocks 703. The linkage rack 607 meshes with the linkage gear 702. The left-hand thread and the right-hand thread of the bidirectional lead screw 701 are respectively threaded to one of the moving blocks 703. The bottom of the moving block 703 is provided with a first rotating seat 704. The anti-slip component includes an anti-slip toothed plate 707. The top of the anti-slip toothed plate 707 is provided with a second rotating seat 706. The two ends of the rotating rods 705 are respectively rotatably connected to the first rotating seat 704 and the second rotating seat 706. The two rotating rods 705 are set in opposite inclination directions.

[0057] The linkage groove 4 is provided with the bidirectional lead screw 701 and the rotating rod 705. The two moving blocks 703 move closer to each other or further away from each other as the bidirectional lead screw 701 rotates. The rotating rod 705 rotates out of the linkage groove 4 or retracts into the linkage groove 4.

[0058] like Figure 1 As shown, the height of the movable wheel 2 is greater than the height of the anti-slip toothed plate 707 and the extrusion cylinder 605 relative to the bottom of the support plate 1 in the initial state. The push handle 3 is fixedly connected to one end of the top of the support plate 1. The push handle 3 is used to push the device.

[0059] Working Principle: When in use, because the height of the moving wheel 2 is greater than that of the anti-slip toothed plate 707 and the extrusion cylinder 605 in their initial state, the device can first be moved to the test position using the moving wheel 2 and the push handle 3. Then, the electric hydraulic rod 602 is activated, sequentially driving the T-shaped plate 603 and the linkage rack 607 downwards. Simultaneously, the linkage rack 607, through meshing, sequentially drives the linkage gear 702 and the double-acting screw 701 to rotate. At this time, the double-acting screw 701 drives the moving blocks 703 to move closer together. The rotating rod 705 rotates using the first rotating seat 704 and the second rotating seat 706, while simultaneously pushing the anti-slip toothed plate 707 to gradually contact the ground, completing the support operation for the device. Afterwards, the linkage rack 607 disengages from the linkage gear 702, the linkage gear 702 is no longer driven, and the anti-slip toothed plate 707 will stably remain on the ground. After contacting and maintaining the height, the electric hydraulic rod 602 continues to drive the T-shaped plate 603 downward. The T-shaped plate 603 drives the pressure gauge 604 and the extrusion cylinder 605 to press into the on-site backfill subgrade to be tested, advancing to a fixed depth. After the test is completed, the electric hydraulic rod 602 drives the T-shaped plate 603 upward. The linkage rack 607 gradually re-engages with the linkage gear 702 and drives the linkage gear 702 to reverse. At the same time, the linkage gear 702 drives the bidirectional lead screw 701 to reverse. The bidirectional lead screw 701 drives the moving block 703 to move away from each other. The rotating rod 705 rotates with the help of the first rotating seat 704 and the second rotating seat 706. At the same time, the rotating rod 705 pulls the anti-slip toothed plate 707 away from the ground. After that, the height of the moving wheel 2 is again greater than that of the anti-slip toothed plate 707 and the extrusion cylinder 605. At this time, the device can be pushed again to change the test location.

[0060] The present invention discloses a field soil compaction testing device for roadbeds. The driving component sequentially lowers the moving component and the testing component, enabling the testing component to perform testing operations. Simultaneously, the moving component lowers, and the transmission component lowers the anti-slip component for support. This device requires only one drive source to achieve the lifting and lowering of both the testing and anti-slip components. It uses minimal energy-consuming equipment, reducing the cost of the device. The device has a simple structure, is easy to use, and performs well.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
