Description

Technical Field

[0001] This utility model relates to the field of road material testing technology, and in particular to a green road material production monitoring device. Background Technology

[0002] Green pavement materials include recycled asphalt concrete, recycled aggregates, and other materials. During the production and processing of these materials, sampling tests are conducted to determine their compressive strength and whether they are qualified. This process monitors the products and ensures that the production of green pavement materials meets the standards for use.

[0003] A search revealed Chinese patent CN221860097U, which discloses a multifunctional road material strength testing machine. However, in the application of this patented technology, the tested road material falls into the gap between the circular fixed column and the protective components, making it difficult for workers to clean. Furthermore, the tested road material is not easily visible to workers, affecting the testing and use of the road surface. Therefore, to advance industry technology, better realize the monitoring function of road material production, and improve core technological competitiveness, this application proposes a new implementation scheme that differs from the structure and application method of the monitoring device in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing production monitoring devices, where the detected road surface material falls into the gap between the circular fixed column and the protective component, making it inconvenient for operators to clean up, and the detected road surface material is not easily visible to operators. Therefore, a green road surface material production monitoring device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A green pavement material production monitoring device includes a base, a support frame fixedly connected to the top of the base, two threaded rods rotatably mounted on the top of the support frame via interlocking bearings, the bottom ends of the threaded rods rotatably connected to the top of the base via interlocking bearings, a sliding plate threaded between the two threaded rods, a connecting column fixedly connected to the bottom of the sliding plate, a pressure detection component provided at the bottom end of the connecting column, a plurality of second sliding rods slidably inserted into the top of the sliding plate, a second limiting ring fixedly connected to the top end of the second sliding rods, a common connecting ring fixedly connected to the bottom end of the plurality of second sliding rods, a double-layer tempered glass tube snapped into the bottom of the connecting ring, and a rubber ring snapped into the bottom end of the double-layer tempered glass tube.

[0007] Furthermore, the pressure detection assembly includes a connecting seat, which is fixed to the bottom end of the connecting column by bolts, and a pressure sensor is fixedly connected to the bottom of the connecting seat.

[0008] Furthermore, the pressure sensor has a pressure block at its bottom, and a plurality of first slide rods are fixedly connected to the top of the pressure block. The top of the first slide rod is slidably inserted into the connecting seat, and a first limiting ring is fixedly connected to the top of the first slide rod.

[0009] Furthermore, a mounting bracket is fixedly connected to the top outer wall of the support frame, and a drive motor is fixedly connected to the top of the mounting bracket. The output end of the drive motor is fixedly connected to the top end of one of the threaded rods, and a sprocket is keyed to the top end of the threaded rod. A chain is connected between the two sprockets for transmission.

[0010] Furthermore, the top inner wall of the support frame is fixedly connected to the top of the base with multiple guide rods, and the sliding plate slides between the multiple guide rods.

[0011] Furthermore, a fixed seat is fixedly connected to the top of the base, and a support plate is provided on the top of the fixed seat.

[0012] Furthermore, the top of the fixed base is fixedly connected with multiple positioning blocks, and the bottom of the bearing plate is provided with multiple positioning grooves, with the positioning blocks engaging with the positioning grooves.

[0013] Furthermore, a control host and a display screen are fixedly connected to one outer wall of the support frame, and the control host is electrically connected to the display screen, pressure sensor and drive motor.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Driven by the motor and the chain, two threaded rods rotate simultaneously, causing the sliding plate to move downwards. This, in turn, moves the double-layered tempered glass cylinder downwards to cover the outside of the bearing plate, thus preventing the fragments from scattering indiscriminately when the green pavement material breaks. This also facilitates subsequent handling by staff. The double-layered tempered glass cylinder allows for direct observation of the testing status of the green pavement material.

[0016] 2. The drive motor rotates the threaded rod, which in turn moves the sliding plate downwards, causing the connecting column and pressure detection assembly to move downwards. This allows the pressure block to press onto the green pavement material, thus applying pressure to the material. The operation is simple, time-saving, and labor-saving.

[0017] 3. By sliding the top of the first slide rod into the connecting seat, the movement of the pressure block is guided, thereby improving the stability of applying pressure to the green pavement material and increasing the accuracy of the test. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A green pavement material production monitoring device includes a base 1, a support frame 2 fixed to the top of the base 1 by bolts, two threaded rods 3 rotatably mounted on the top of the support frame 2 by interlocking bearings, the bottom end of the threaded rods 3 rotatably connected to the top of the base 1 by interlocking bearings, a sliding plate 4 threadedly connected between the two threaded rods 3, a connecting column 5 fixed to the bottom of the sliding plate 4 by bolts, and a pressure detection component 6 provided at the bottom end of the connecting column 5.

[0026] A mounting bracket is bolted to the top outer wall of the support frame 2. A drive motor 12 is bolted to the top of the mounting bracket. The output end of the drive motor 12 is fixedly connected to the top of one of the threaded rods 3. A sprocket 13 is keyed to the top of the threaded rod 3. A chain 14 is connected between the two sprockets 13. Multiple second sliding rods 7 are slidably inserted into the top of the sliding plate 4. A second limiting ring 11 is welded to the top of the second sliding rod 7. The same connecting ring 8 is welded to the bottom of the multiple second sliding rods 7. A double-layer tempered glass cylinder 9 is snapped into the bottom of the connecting ring 8. Driven by the drive motor 12 and driven by the chain 14, the two threaded rods 3 rotate simultaneously, causing the sliding plate 4 to move downward. Then, the connection between the second sliding rods 7 and the connecting ring 8 causes the double-layer tempered glass cylinder 9 to move downward, so that the double-layer tempered glass cylinder 9 covers the outside of the green pavement material, thus preventing the fragments from scattering when the green pavement material breaks and facilitating subsequent handling by workers. A rubber ring 10 is snapped into the bottom of the double-layer tempered glass cylinder 9.

[0027] The pressure detection component 6 includes a connecting seat 601, which is fixed to the bottom of the connecting column 5 by bolts. A pressure sensor 602 is fixed to the bottom of the connecting seat 601 by bolts. A pressure block 603 is provided at the bottom of the pressure sensor 602. The threaded rod 3 continues to rotate, driving the sliding plate 4 to move downward, thereby driving the connecting column 5 and the pressure detection component 6 to move downward, so that the pressure block 603 presses on the green pavement material, thereby applying pressure to the green pavement material, detecting its compressive strength, and judging whether it is qualified, thus achieving the effect of monitoring product production.

[0028] Multiple first slide rods 604 are welded to the top of the pressure block 603. The top of the first slide rod 604 is slidably inserted into the connecting seat 601, thereby guiding the movement of the pressure block 603, thereby improving the stability of applying pressure to the green pavement material and improving the accuracy of the test. A first limiting ring 605 is welded to the top of the first slide rod 604 to prevent the first slide rod 604 from disengaging from the connecting seat 601.

[0029] Multiple guide rods 15 are welded to the top inner wall of the support frame 2 and the top of the base 1 to guide the sliding plate 4. The sliding plate 4 slides between the multiple guide rods 15.

[0030] The top of the base 1 is fixed with a fixing seat 16 by bolts. The top of the fixing seat 16 is provided with a bearing plate 17. Multiple positioning blocks 19 are welded to the top of the fixing seat 16. Multiple positioning grooves 18 are provided at the bottom of the bearing plate 17. The positioning blocks 19 are engaged with the positioning grooves 18. The bearing plate 17 is installed on the fixing seat 16 by engaging the positioning blocks 19 with the positioning grooves 18, thereby facilitating the alignment of the bearing plate 17 and the fixing seat 16.

[0031] The control host 20 and the display screen 21 are fixed to one side of the outer wall of the support frame 2 by bolts. The control host 20 is electrically connected to the display screen 21, the pressure sensor 602 and the drive motor 12. The drive motor 12 is model SAF99 and the pressure sensor is model 9017A100. Other models can also be selected according to actual needs.

[0032] The working principle of this embodiment is as follows: First, the green pavement material is placed on the support plate 17. Then, the support plate 17 is installed on the fixed base 16 by the engagement of the positioning block 19 and the positioning groove 18. Next, the drive motor 12 is started by the control host 20. Under the drive of the drive motor 12 and the transmission action of the chain 14, the two threaded rods 3 rotate simultaneously, causing the sliding plate 4 to move downwards. Furthermore, the connection between the second sliding rod 7 and the connecting ring 8 causes the double-layer tempered glass cylinder 9 to move downwards, thus covering the outside of the support plate 17. Then… The threaded rod 3 continues to rotate, causing the sliding plate 4 to move downward, which in turn causes the connecting column 5 and the pressure detection component 6 to move downward, so that the pressure block 603 presses on the green pavement material. The drive motor 12 drives the pressure block 603 to apply pressure to the green pavement material until the green pavement material is observed to break through the double-layer tempered glass tube 9. During this process, the pressure block 603 will squeeze the pressure sensor 602 upward, thereby applying pressure to the pressure sensor 602, and thus detecting the force applied to the green pavement material and displaying it on the display screen 21, thereby completing the pressure test on the green pavement material.

[0033] During the test, the fragments of the broken green pavement material were contained within the double-layered tempered glass cylinder 9, preventing the fragments from scattering indiscriminately and facilitating subsequent handling by staff.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
