Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt material detection, and particularly relates to an environment-friendly asphalt ductility detection device. Background Art

[0002] In the fields of traffic construction and road maintenance, asphalt materials are widely used due to their unique physical and chemical properties. Among them, the ductility of asphalt is one of the key indicators for evaluating its quality and service performance, directly reflecting the extensibility and crack resistance of asphalt under external forces. Therefore, accurately and efficiently detecting the ductility of asphalt is crucial for ensuring the quality and durability of road projects.

[0003] However, there are still some limitations in the design and use of existing asphalt ductility detection devices on the market. Firstly, the stretching frame in these devices is often designed to be large in size. When stretching asphalt, it is easy to generate large water flow disturbances in the water tank. Such disturbances are likely to cause the asphalt to break prematurely, resulting in inaccurate detection results and affecting the reliability of evaluation. Secondly, when conducting asphalt ductility detection, these devices usually need to be filled with a large amount of liquid inside. However, after the detection is completed, this liquid is often directly discarded and cannot be effectively stored and reused. This not only causes waste of resources, increases costs, but also goes against the current concepts of environmental protection and energy conservation.

[0004] Therefore, it is very necessary to invent an environment-friendly asphalt ductility detection device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an environment-friendly asphalt ductility detection device to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to an environment-friendly asphalt ductility detection device, which comprises a box body, a first partition board, a water pump, a stirring shaft, a first motor, a guide post, a stretching frame, a lead screw, a second motor, a second partition board, a water inlet pipe, a box door, a drain pipe and a measuring scale. The inside of the box body is fixedly welded with a first partition board and a second partition board respectively. A water pump is fixedly bolted to the lower side surface of the first partition board. Two stirring shafts are arranged on the lower side of the first partition board. The outer sides of both ends of the stirring shaft are rotatably connected with the box body through supporting bearings, and one end of the stirring shaft is fixed to the output end of the first motor, and the first motor is fixedly bolted to the outer side surface of the box body. A guide post and a lead screw are arranged between the first partition board and the second partition board. Both ends of the guide post are fixedly welded to the inner wall of the box body, and two stretching frames are slidably mounted on the outer side surface of the guide post. The two stretching frames are symmetrically arranged. The middle part of the stretching frame is slidably connected with the second partition board. Both ends of the lead screw are rotatably connected with the box body through supporting bearings, and one end of the lead screw is fixed to the output end of the second motor, and the second motor is fixedly bolted to the outer side surface of the box body. Two sections of external threads with opposite helix directions are arranged on the outer side surface of the lead screw. The lead screw passes through two stretching frames through two sections of external threads with opposite helix directions. One side of the box body is fixedly provided with a water inlet pipe and a drain pipe through valves respectively, and a box door is arranged on one side of the water inlet pipe. The box door is rotatably connected with the box body through a hinge. A measuring scale is fixedly bolted to the front side surface of the box body.

[0008] Furthermore, the stretching frame comprises a base, a first magnet, a column and a mold. Guide posts are respectively slidably penetrated through the inner parts of both ends of the base, and the lead screw is penetrated through the inside of the base through thread engagement. A first magnet is fixedly bolted to one side of the base close to the measuring scale, and a column is fixedly welded to the upper side surface of the base. The middle part of the column is movably arranged inside the second partition board. A mold is fixedly bolted to the upper end of the column. The mold is arranged above the second partition board. During use, the asphalt can be fixed on the corresponding mold, and then through the cooperation of the lead screw and the second motor, the two stretching frames move away from each other, so as to stretch the asphalt inside the mold. Secondly, during the stretching process of the asphalt, the second partition board can reduce the water flow disturbance generated when the base moves, thereby improving the detection accuracy.

[0009] Furthermore, the measuring ruler includes a housing, a second magnet, and a glass plate. The housing is fixed to the outer side of the box body by bolts, and two second magnets are slidably installed inside the housing, with the second magnets arranged corresponding to the first magnets; a glass plate is fixed to the outer side of the housing by bolts, and scale lines are engraved on the outer side of the glass plate. When the two stretching frames move relative to each other, the adsorption force between the first magnet and the second magnet can drive the second magnet to slide inside the housing. At this time, the staff can determine the stretching length of the asphalt by observing the position of the second magnet inside the housing and then combining the scale lines on the glass plate.

[0010] Compared with the prior art, the present utility model has the following beneficial effects:

[0011] With the present utility model, firstly, when detecting the ductility of asphalt, the asphalt can be fixed on the corresponding mold, and then through the cooperation of the lead screw and the second motor, the two stretching frames move away from each other to stretch the asphalt inside the mold. During the stretching process of the asphalt, the second partition plate can reduce the water flow disturbance generated when the base moves, thereby improving the detection accuracy. Moreover, the staff can determine the stretching length of the asphalt by observing the position of the second magnet inside the housing; secondly, after use, the liquid above the first partition plate can be pumped to the lower side of the first partition plate for storage through a water pump. Then, when used for the second time, the liquid on the lower side of the first partition plate can be pumped to the upper side of the first partition plate again through the water pump. The staff can supplement or replace the liquid on the lower side of the first partition plate through the water inlet pipe and the drain pipe. Thus, through the recycling of the liquid, the waste of the liquid is reduced. Description of the Drawings
