Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement testing technology, and in particular to an asphalt pavement testing device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavement types in road construction.

[0003] In the prior art, such as the asphalt pavement testing device with announcement number CN219104658U, there is a water tank. L-shaped rods are fixedly installed on both sides of the top of the water tank, and a water cylinder is fixedly installed between the two L-shaped rods. A piston is installed inside the water cylinder, and a first electric cylinder is fixedly installed on the top of the water cylinder. This invention facilitates the testing of the waterproofness of asphalt pavement samples by changing the water pressure, improving the accuracy and efficiency of the test. Simultaneously, the test water can be recycled and reused. However, the existing asphalt pavement testing device has the problem of not being able to perform compressive strength testing on asphalt pavement. Therefore, this invention proposes an asphalt pavement testing device for testing the compressive strength of asphalt. Utility Model Content

[0004] In view of this, the present invention aims to provide an asphalt pavement testing device to solve or alleviate the technical problems existing in the prior art. By installing a first hydraulic cylinder, the extrusion plate can be pushed to slide, thereby extruding the asphalt pavement. This allows the pressure sensor to display the pressure of the asphalt pavement in real time, enabling the device to test the compressive strength of the asphalt pavement.

[0005] The technical solution of this utility model embodiment is implemented as follows:

[0006] An asphalt pavement testing device includes a fixing assembly. A pressure sensor is fixedly mounted on the fixing assembly, and a first sliding plate is slidably mounted thereon. A first hydraulic cylinder is fixedly mounted on the first sliding plate. A pressing plate and a second sliding plate are fixedly mounted on the output end of the first hydraulic cylinder. Two second hydraulic cylinders are fixedly mounted on the second sliding plate, and a sliding frame is fixedly mounted on the output end of the two second hydraulic cylinders. Four motors are fixedly mounted on the sliding frame, and rotating wheels are fixedly mounted on the output end of each of the four motors. A water tank is placed at the bottom of the fixing assembly, and a water pump is fixedly mounted inside the water tank. A water guide pipe is fixedly mounted on the output end of the water pump, and a water outlet pipe is fixedly mounted on one end of the water guide pipe.

[0007] Preferably, the fixing component includes a fixing base and a fixing plate fixedly mounted on the fixing base. The lower side of the fixing base is provided with four support legs for supporting the device, and the lower side of the fixing plate is provided with four connecting protrusions fixedly connected to the fixing base. The support legs facilitate the support of the device.

[0008] Preferably, four first guide rods, each penetrating the fixed plate, are fixedly installed on the first sliding plate. The first hydraulic cylinder is located below the pressure sensor. The installation of the first guide rods can guide the first sliding plate during the sliding process, thereby making the first sliding plate slide more smoothly.

[0009] Preferably, four second guide rods, each penetrating the second sliding plate, are fixedly installed on the sliding frame. The extrusion plate is located on the lower side of the second sliding plate. The sliding frame has an inverted U-shaped structure. The installation of the extrusion plate can extrude the asphalt pavement, making it convenient for the device to inspect the asphalt pavement.

[0010] Preferably, the fixed base has two threaded push rods inside the threaded engagement for pushing out the asphalt pavement. The fixed base has two threaded holes corresponding to the two threaded push rods. When the threaded push rods are rotated, they slide upwards, and the asphalt pavement on the threaded push rods is pushed out. The installation of the threaded push rods makes it easy for workers to remove the asphalt pavement from the device.

[0011] Preferably, the fixing seat has a cavity for placing the asphalt pavement, and the fixing seat is provided with a water-guiding protrusion for water circulation. The water outlet pipe is fixedly installed inside the fixing seat and has multiple water outlet holes. The water outlet pipe is connected to the water guide pipe and the water pump. When water comes out of the water outlet pipe, the water wets the asphalt pavement. Then the water flows into the water tank after passing through the water guide protrusion. The water guide protrusion facilitates the circulation of water.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model, through the installation of a first hydraulic cylinder, can push the extrusion plate to slide, thereby allowing the extrusion plate to extrude asphalt pavement, so that the pressure sensor can display the pressure of the asphalt pavement in real time, thus enabling the device to detect the compressive strength of the asphalt pavement.

[0014] II. This utility model, through the installation of a motor, can drive a rotating wheel to rotate, and the installation of a water pump can spray water onto the asphalt road surface, thereby enabling the device to detect the service life of the asphalt road surface in water.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, this utility model embodiment provides an asphalt pavement testing device, including: a fixing component 1, on which a pressure sensor 2 is fixedly installed, a first sliding plate 3 is slidably configured, a first hydraulic cylinder 4 is fixedly installed on the first sliding plate 3, a pressing plate 5 and a second sliding plate 6 are fixedly installed on the output end of the first hydraulic cylinder 4, two second hydraulic cylinders 7 are fixedly installed on the second sliding plate 6, a sliding frame 8 is fixedly installed on the output end of the two second hydraulic cylinders 7, four motors 9 are fixedly installed on the sliding frame 8, and rotating wheels 10 are fixedly installed on the output end of each of the four motors 9, a water tank 11 is placed at the bottom of the fixing component 1, a water pump 12 is fixedly installed in the water tank 11, a water guide pipe 13 is fixedly installed on the output end of the water pump 12, and a water outlet pipe 14 is fixedly installed at one end of the water guide pipe 13.

[0025] In this embodiment, specifically: the fixing component 1 includes a fixing base 15 and a fixing plate 16 fixedly installed on the fixing base 15. The lower side of the fixing base 15 is provided with four support legs for supporting the device. The lower side of the fixing plate 16 is provided with four connecting protrusions that are fixedly connected to the fixing base 15. The setting of the connecting protrusions facilitates the fixed connection between the fixing base 15 and the fixing plate 16.

[0026] In this embodiment, specifically: four first guide rods 17, each penetrating the fixed plate 16, are fixedly installed on the first sliding plate 3; the first hydraulic cylinder 4 is located below the pressure sensor 2; the installation of the pressure sensor 2 facilitates the display of the pressure on the asphalt pavement.

[0027] In this embodiment, specifically: four second guide rods 18, each penetrating the second sliding plate 6, are fixedly installed on the sliding frame 8. The pressing plate 5 is located on the lower side of the second sliding plate 6. The sliding frame 8 has an inverted U-shaped structure. The installation of the second guide rods 18 can guide the sliding frame 8 during the sliding process, thereby making the sliding frame 8 slide more smoothly.

[0028] In this embodiment, specifically: the internal threaded engagement of the fixed seat 15 provides two threaded push rods 19 for pushing out the asphalt pavement, and the fixed seat 15 has two threaded holes corresponding to the two threaded push rods 19. The opening of the threaded holes facilitates the threaded engagement between the threaded push rods 19 and the fixed seat 15.

[0029] In this embodiment, specifically: the fixed base 15 has a cavity for placing the asphalt pavement, the fixed base 15 is provided with a water guiding protrusion for water circulation, the water outlet pipe 14 is fixedly installed inside the fixed base 15, the water outlet pipe 14 has multiple water outlet holes, the water outlet pipe 14 is interconnected with the water guiding pipe 13 and the water pump 12, the opening of the cavity makes it difficult for the water sprayed from the water outlet pipe 14 to splash.

[0030] When this utility model is in operation: when the device needs to test the compressive strength of asphalt pavement, the first hydraulic cylinder 4 is activated. The activation of the first hydraulic cylinder 4 causes the extrusion plate 5 to slide downward. The asphalt pavement sample should be placed under the extrusion plate 5 beforehand. When the extrusion plate 5 contacts the upper surface of the asphalt pavement, the first hydraulic cylinder 4 will drive the first sliding plate 3 to slide upward. The upward sliding first hydraulic cylinder 4 extrudes the pressure sensor 2, and the pressure on the asphalt pavement is displayed on the pressure sensor 2, thus detecting the compressive strength of the asphalt pavement.

[0031] When the device needs to detect the service life of asphalt pavement in water, the second hydraulic cylinder 7 needs to be activated first. The activation of the second hydraulic cylinder 7 drives the sliding frame 8 to slide, which in turn drives the motor 9 and the rotating wheel 10 to slide downwards. After sliding, the rotating wheel 10 contacts the asphalt pavement, and the first hydraulic cylinder 4 contacts the pressure sensor 2. The pressure sensor 2 then displays the magnitude of the compressive force on the asphalt pavement. At this time, the water pump 12 is activated. After the water pump 12 is activated, the water passes through the water pump 12, the water guide pipe 13, and the water outlet pipe 14 in sequence, and then the water wets the asphalt pavement. At this time, the motor 9 is activated, which drives the rotating wheel 10 to rotate. During the rotation of the rotating wheel 10, it rubs against the asphalt pavement, thus simulating the service life of the asphalt pavement in water due to the friction of a wheel.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
