Description

Technical Field

[0001] This utility model relates to the field of road testing technology, specifically a universal testing machine for road substrates. Background Technology

[0002] Asphalt roads refer to various types of pavements constructed by incorporating road asphalt materials into mineral materials. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in smooth, dust-free, impermeable, and durable surfaces. Therefore, asphalt roads are one of the most widely used high-grade pavements in road construction. While the asphalt structural layer itself falls under the category of flexible pavements, its base layer can also utilize rigid cement concrete or semi-rigid hydraulic materials in addition to flexible materials. Asphalt roads are exposed to the natural environment and are frequently subjected to rainwater erosion, leading to water damage that makes the pavement prone to peeling and significantly shortens its service life. Simulating the erosion and degradation of asphalt roads by natural rainwater is crucial for researchers to study the erosion and damage patterns of asphalt roads and to provide a reference for the design and improvement of asphalt roads. Therefore, an asphalt road testing machine is needed to simulate rainwater erosion.

[0003] According to a search, Chinese patent document, publication number CN217896153U, discloses an asphalt road testing machine. Through the arrangement of a water storage tank, a transparent plate, and scale lines, the transparent plate displays the water level in the storage tank, and the scale lines on the transparent plate allow for precise reading of the water level, facilitating the determination of whether water needs to be added. This gives the asphalt road testing machine a water level display structure, enabling operators to accurately determine the water level. Furthermore, the design incorporates a water suction pipe and a honeycomb mesh head. The honeycomb mesh head filters out impurities when water is drawn into the suction pipe, preventing impurities from entering and causing blockages. This gives the asphalt road testing machine an impurity filtration structure, effectively preventing pipe blockages. However, during use, the nozzle sprays water from the source and impacts the asphalt road, which can easily cause the test road to shift, affecting the detection accuracy. It can also cause splashing, which can lead to water spilling out of the device, resulting in waste and affecting the viewing. At the same time, although the honeycomb mesh head can prevent impurities from entering the pipe and causing blockage, impurities accumulate inside the water storage tank, gradually submerging the honeycomb mesh head and causing blockage, affecting the water delivery effect. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a universal testing machine for road substrates. It features a filtering effect, reducing clogging, and a stable device that can limit the simulated road to improve stability and prevent water splashing, thus avoiding resource waste and interference with inspection. This solves the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a universal testing machine for road substrates, comprising a base, a conveyor seat fixedly installed on the bottom side of the base, a filter box movably installed on the inner side of the conveyor seat, a water collection tank bolted to the bottom side of the conveyor seat, a pump connected to the rear side of the water collection tank via a pipe, a diverter connected to the outlet of the pump via a pipe, a support frame fixedly installed on the top side of the base, and a splash guard movably installed on the bottom side of the support frame.

[0008] Preferably, a partition is fixedly installed on the top side of the base, and a plurality of equally spaced through slots are opened on the top side of the partition. A fitting groove is opened on the front side of the conveyor seat, and limit slots are opened on the left and right sides of the inner side of the fitting groove. Connecting holes are opened at the four corners of the bottom side of the conveyor seat.

[0009] With the above technical solution, during the test, the simulated road is placed inside the groove on the top side of the machine base. Subsequently, during use, the partition not only helps to improve the uniformity of support, but also avoids direct contact between the simulated road and the groove, which would lead to a decrease in the infiltration rate of simulated rainwater in the later stage.

[0010] Preferably, limit strips are fixedly installed on the left and right sides of the filter box, the size and shape of the limit grooves match the limit strips, and a filter screen is provided on the inner side of the filter box. A threaded hole is opened on the top side of the water collection tank, and the threaded hole corresponds one-to-one with the connecting hole.

[0011] With the above technical solution, during the infiltration process, the water source enters the delivery seat and is filtered through the filter screen inside the filter box. Moreover, it is easy to pull out the filter box for cleaning later. The threaded hole makes it easy to use bolts to connect the delivery seat, which is convenient for disassembly, assembly and installation.

[0012] Preferably, the diversion frame includes a main pipe, a branch pipe, and a diversion pipe. A diversion pipe is provided between the main pipe and the branch pipe. There are a total of two branch pipes. Several nozzles are arranged at equal intervals on the bottom side of the main pipe and the branch pipe.

[0013] With the above technical solution, during the simulation test, water is delivered to the main pipe by the pump, and then diverted to the branch pipe by the diversion pipe, thus facilitating the spraying of simulated rainwater onto the simulated road through multiple nozzles.

[0014] Preferably, a fixing sleeve is fixedly installed on the bottom side of the support frame, the fixing sleeve has a movable cavity on the bottom side, and the diverter is fixedly installed on the inner side of the fixing sleeve.

[0015] Through the above technical solution, the splash guard can move and extend within the movable cavity, making it easy to adjust and use. At the same time, the fixed sleeve helps to prevent splashing when the nozzle sprays water.

[0016] Preferably, the splash guard is made of transparent material, and the size and shape of the splash guard match the movable cavity. An electric push rod and a telescopic rod are fixedly installed between the splash guard and the support frame, respectively.

[0017] Through the above technical solution, during the test, the electric push rod is activated to move the splash guard downward and squeeze and limit the surrounding area of ​​the simulated road. This helps to prevent the simulated road from being affected by the simulated rain, thus affecting the test accuracy. Moreover, during the simulated rain, the splash guard helps to prevent water from splashing, which would waste resources and affect the staff's observation.

[0018] Compared with the prior art, this utility model provides a universal testing machine for road substrates, which has the following beneficial effects:

[0019] 1. This utility model places the simulated road inside the groove on the top side of the base. During use, the partition not only helps to improve the uniformity of support, but also avoids direct contact between the simulated road and the groove, which would lead to a decrease in the infiltration rate of simulated rainwater later. Then, when conducting simulation tests, the electric push rod is activated to move the splash guard down and squeeze and limit the simulated road around its perimeter. This helps to prevent the simulated road from being affected by the side wings during simulated rainwater, thus affecting the test accuracy. Moreover, during the simulated rainwater process, the splash guard helps to prevent water from splashing, which would waste resources and affect the staff's observation.

[0020] 2. In this utility model, after the water source enters the conveying seat during the infiltration process, it is filtered through the filter screen inside the filter box. Moreover, it is easy to pull out the filter box for cleaning later, which avoids impurities entering the circulation pipe and causing blockage, and facilitates cleaning. At the same time, since the conveying seat and the water collection tank are fixed by bolts, it is easy to disassemble later, thus making it easy to clean the water collection tank.

[0027] 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.

[0028] Example 1:

[0029] like Figures 1-5 As shown, the universal testing machine for road substrates provided by this utility model includes a base 1, a conveyor seat 2 fixedly installed on the bottom side of the base 1, a filter box 3 movably installed on the inner side of the conveyor seat 2, a water collection tank 4 bolted to the bottom side of the conveyor seat 2, a pump 5 connected to the rear side of the water collection tank 4 via a pipe, a diverter 6 connected to the outlet end of the pump 5 via a pipe, a support frame 7 fixedly installed on the top side of the base 1, and a splash guard 8 movably installed on the bottom side of the support frame 7.

[0030] Specifically, a partition plate 101 is fixedly installed on the top side of the base 1. Several equally spaced through slots are formed on the top side of the partition plate 101. A fitting groove 201 is formed on the front side of the conveyor seat 2. Limiting grooves 202 are formed on the left and right sides of the inner side of the fitting groove 201. Connecting holes 203 are formed at the four corners of the bottom side of the conveyor seat 2. The advantage is that by placing the simulated road inside the groove on the top side of the base 1, the partition plate 101 not only improves the uniformity of support during use but also prevents direct contact between the simulated road and the groove, thus avoiding a decrease in the simulated rainwater infiltration rate later.

[0031] Specifically, limit strips are fixedly installed on the left and right sides of the filter box 3, and the size and shape of the limit groove 202 match the limit strips. A filter screen 301 is provided inside the filter box 3, and a threaded hole 401 is opened on the top side of the water collection tank 4, with the threaded hole 401 corresponding one-to-one with the connecting hole 203. The advantages are that after water enters the conveyor seat 2, it is filtered by the filter screen 301 inside the filter box 3, and the filter box 3 is easy to pull out for cleaning later. The threaded hole 401 facilitates bolt connection to the conveyor seat 2, making disassembly and assembly convenient.

[0032] Specifically, the diversion frame 6 includes a main pipe 601, branch pipes 602, and diversion pipes 603. The diversion pipe 603 is installed between the main pipe 601 and the branch pipes 602. There are two branch pipes 602 in total, and several equally spaced nozzles are installed on the bottom sides of the main pipe 601 and the branch pipes 602. The advantage is that water is supplied to the main pipe 601 by the pump 5, and then diverted to the branch pipes 602 by the diversion pipes 603, thus facilitating the spraying of simulated rainwater onto the simulated road using multiple nozzles.

[0033] Example 2:

[0034] like Figures 1-5 As shown, this is an improvement on the previous embodiment. Specifically, a fixed sleeve 701 is fixedly installed on the bottom side of the support frame 7, and a movable cavity 702 is opened on the bottom side of the fixed sleeve 701. The diverter 6 is fixedly installed inside the fixed sleeve 701. The advantage is that the movable cavity 702 facilitates the movement and extension of the splash guard 8, thereby making it easy to adjust and use. At the same time, the fixed sleeve 701 helps to prevent splashing when the nozzle sprays water.

[0035] Specifically, the splash guard 8 is made of transparent material, and its size and shape match the movable cavity 702. An electric push rod 801 and a telescopic rod 802 are fixedly installed between the splash guard 8 and the support frame 7. The advantage is that by activating the electric push rod 801, the splash guard 8 is moved downwards, and the surrounding area of ​​the simulated road is compressed and limited. This helps to prevent the simulated road from being affected by rainwater, thus ensuring the accuracy of the test. Furthermore, during the simulated rainwater process, the splash guard 8 helps to prevent water from splashing, thus avoiding resource waste and hindering the staff's observation.

[0036] During use, the simulated road is placed inside the groove on the top side of the base 1. The partition 101 not only improves the uniformity of support but also prevents direct contact between the simulated road and the groove, thus avoiding a decrease in the simulated rainwater infiltration rate. During the simulation test, the electric push rod 801 moves the splash guard 8 downwards, squeezing and limiting the simulated road's perimeter. This helps prevent the simulated road from fluttering during simulated rainwater, thus avoiding impact on test accuracy. Furthermore, the splash guard 8 helps prevent water from splashing during the simulated rainwater process, preventing resource waste and hindering staff observation. After infiltration, the water enters the conveyor seat 2 and is filtered through the filter screen 301 inside the filter box 3. The filter box 3 is easy to pull out for cleaning, preventing impurities from entering the circulation pipe and causing blockages, and facilitating cleaning. Since the conveyor seat 2 and the water collection tank 4 are fixed together with bolts, disassembly is convenient, making it easy to clean the water collection tank 4.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
