Description

Technical Field

[0001] The utility model relates to the technical field of material testing, in particular to a detection device for the expansibility of steel slag asphalt mixture. Background Technique

[0002] After retrieving the patent document with the publication number of CN219799454U, this patent document is provided with a feeding mechanism. There are pulleys under the mold to make the mold slide inside two guide rods, and the mold is fed into the box body. By providing a wheel groove at the bottom of the box body, the pulleys are limited to prevent the pulleys from moving;

[0003] After the detection of the mixture sample in this patent document is completed, when detecting the next mixture sample, since the previous mixture sample in the mold has not been taken out, other mixture samples cannot be detected, resulting in interrupted detection and increasing the time cost of detection. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] The present utility model will be further described below with reference to the drawings:

[0026] As Figures 1 - 5 shown, a swelling detection device for steel slag asphalt mixture includes a chassis 1, a guide mechanism 3 is arranged on the top of the chassis 1, a detection mechanism 4 is arranged in front of the guide mechanism 3, a mold 5 is arranged inside the detection mechanism 4, a movable plate 6 is slidably connected inside the mold 5, and a demolding mechanism 2 is further included, and the demolding mechanism 2 is located at the front end of the chassis 1.

[0027] In this embodiment: The guide mechanism 3 includes a guide track 302, the guide track 302 is fixedly connected to the top of the chassis 1, and guide bars 301 are fixedly connected to both sides of the guide track 302. By arranging two guide bars 301, the mold 5 slides on the guide track 302 along the direction of the guide bars 301.

[0028] In this embodiment: The demolding mechanism 2 includes a top plate 203. Below the top plate 203, there is a first cylinder 202. The bottom of the top plate 203 is fixedly connected to the telescopic part of the first cylinder 202. Below the first cylinder 202, there is a fixing frame 201 for fixing it. On both sides of the top plate 203, there are respectively a fixing seat 205 and a collection box 204. The fixing seat 205 and the collection box 204 are both fixedly connected to the top of the bottom frame 1. The top plate 203 is located inside the guiding channel 302. The fixing frame 201 is fixedly connected to the bottom frame 1. After the mixture sample detection is completed, the mold 5 is pushed out along the guiding channel 302, so that the movable plate 6 reaches the position of the top plate 203. The first cylinder 202 pushes the top plate 203 upward, so that the top plate 203 pushes the movable plate 6 upward to eject the mixture sample out of the mold 5. When the movable plate 6 reaches the top of the mold 5, the first cylinder 202 stops pushing. The second cylinder 206 pushes the push plate 207 to push the mixture sample into the collection box 204.

[0029] In this embodiment: The detection mechanism 4 includes a detection box 401. At the front end of the detection box 401, there is a hinged turning door 402. Inside the detection box 401, there is a U-shaped positioning plate 407 for restricting the position of the mold 5. The U-shaped positioning plate 407 is fixedly connected to the bottom of the detection box 401. At the rear end of the detection box 401, there is a water outlet pipe 408. At the rear end of the water outlet pipe 408, there is a water stop valve. On the other side of the detection box 401, there is a fixing rod 403 fixed to the top of the bottom frame 1. At the upper end of the fixing rod 403, there is a connecting plate 404 rotatably connected. At one end of the connecting plate 404 facing the detection box 401, there is a graduated shaft 405 slidably connected. At the lower end of the graduated shaft 405, there is a pressing plate 406. On one side of the turning door 402 that fits with the detection box 401, there are sealing rubber rings for preventing water from flowing out. When the mold 5 enters the detection box 401, the mold 5 pushes the turning door 402 to turn over. After the mold 5 completely enters the detection box 401, the turning door 402 falls. Since there is a rubber sealing ring at the edge of the turning door 402, the turning door 402 and the detection box 401 always remain airtight. The mold 5 moves forward along the U-shaped positioning plate 407 at the bottom of the detection box 401 until the front end of the mold 5 abuts against the front end of the U-shaped positioning plate 407, and the mold 5 stops. The pressing plate 406 is placed on the mixture sample, and the value of the graduated shaft 405 at this time is recorded. Constant temperature water is added to the detection box 401. After a period of time, the pressing plate 406 moves upward. At this time, the value of the graduated shaft 405 is recorded. The water stop valve at the front end of the water outlet pipe 408 is opened to drain the water.

[0030] In this embodiment: Both the top and bottom of the mold 5 are in an open state. The mold 5 is slidably connected to both guiding strips 301, making the mold 5 more stable when sliding on the guiding channel 302.

[0031] Working principle: Place the mold 5 at the position of the top plate 203, put the movable plate 6 in, place the mixture sample in the mold 5, and push the mold 5 to slide on the guide track 302 along the direction of the guide bar 301. The mold 5 pushes the flip door 402 into the detection box 401. When the mold 5 completely enters the detection box 401, the flip door 402 drops. Due to the rubber ring on the flip door 402, the flip door 402 is always kept sealed with the detection box 401 to prevent water from flowing out of the detection box 401 from the flip door 402. The mold 5 moves forward along the U-shaped positioning plate 407 until the front end of the mold 5 abuts against the front end of the U-shaped positioning plate 407. Place the pressing plate 406 on the mixture sample and record the value of the scale shaft 405 at this time. Add constant temperature water into the detection box 401 to submerge the mold 5. After a period of time, the mixture sample expands, and record the value of the scale shaft 405 at this time. Open the water stop valve at the front end of the water outlet pipe 408 to drain the water. Push the mold 5 out of the detection box 401 so that the mold 5 moves along the guide bar 301 to the position of the top plate 203. The first cylinder 202 pushes the top plate 203 to move upward, so that the top plate 203 pushes the movable plate 6 to move upward to push out the mixture sample until the movable plate 6 reaches the top of the mold 5, and the first cylinder 202 stops. The second cylinder 206 pushes the push plate 207 to move, so that the push plate 207 pushes the mixture sample into the collection box 204.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
