[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] The present invention will be further described below in conjunction with the accompanying drawings:

[0024] As Figure 1 - Figure 4 shown, a sealant test and detection device for highway engineering includes an equipment platform 100. A U-shaped frame 200 is provided on the upper surface of the equipment platform 100. The two ends of the U-shaped frame 200 are slidably connected to the equipment platform 100 in the front-rear direction. A mold mechanism is provided on the rear side of the upper surface of the equipment platform 100. The mold mechanism includes mold components symmetrically distributed in the front and rear. The mold components include two L-shaped templates 301. The sides of the two L-shaped templates 301 are in contact with each other. The horizontal plate of the L-shaped template 301 is slidably connected to the equipment platform 100 in the front-rear direction. Dovetail chutes 305 are provided on the sides of the vertical plates of the L-shaped template 301 away from each other. Dovetail slides 304 are slidably connected to the dovetail chutes 305. Side plates 302 are provided on the sides of the vertical plates of the L-shaped template 301 away from each other. The side plates 302 are fixedly connected to the corresponding dovetail chutes 305. Blocking strips 303 are fixedly connected to the inner sides of the side plates 302. The two mold components are close to each other to form a square bucket structure. A first locking mechanism and a detection mechanism are provided on the front side of the front mold component. Two second locking mechanisms are symmetrically distributed on the upper side of the mold mechanism.

[0025] The L-shaped template 301 and the side plate 302 form a mold. The stop bar 303 is used to keep the potting glue inside the mold so that it can be pulled, preventing it from slipping out of the mold during detection. The mutual sliding of the dovetail chute 305 and the dovetail slide bar 304 enables the detachable connection between the side plate 302 and the L-shaped template 301, facilitating the cleaning of the residual potting glue inside.

[0026] The second locking mechanism includes a U-shaped fork 502. The vertical fork of the U-shaped fork 502 is slidably connected to the vertical plate of the L-shaped template 301. A telescopic rod 501 is provided on the upper side of the U-shaped fork 502. The two ends of the telescopic rod 501 are respectively fixedly connected to the U-shaped fork 502 and the U-shaped frame 200. A counterbore matching the U-shaped fork 502 is provided at the top of the locking column 503.

[0027] The telescopic rod 501 is used to control the height of the U-shaped fork 502. The U-shaped fork 502 is used to lock the position of the L-shaped template 301, and thus lock the position of the potting glue. When the front fork of the U-shaped fork 502 is inserted into the rear L-shaped template 301 and the rear fork of the U-shaped fork 502 is inserted into the locking column 503, the locking of the rear L-shaped template 301 is achieved.

[0028] The first locking mechanism includes a locking plate 403. The bottom end of the locking plate 403 is fixedly connected to one side of the equipment platform 100 where it is located. The locking plate 403 is provided with a locking hole 404.

[0029] The locking plate 403 is used to provide the locking hole 404, and the locking hole 404 is used to insert the I-shaped column 402.

[0030] The first locking mechanism includes an I-shaped column 402. One side of the I-shaped column 402 is slidably connected to the locking hole 404. A sliding sleeve 401 is fixedly connected to the front side of the L-shaped template 301 on the same side. The sliding sleeve 401 is slidably connected to the middle of the I-shaped column 402.

[0031] The sliding sleeve 401 is used to keep the I-shaped column 402 slidable. When the I-shaped column 402 is inserted into the locking hole 404, the position of the L-shaped template 301 on the same side is locked. When the I-shaped column 402 leaves the locking hole 404, it approaches the L-shaped template 301 on the other side, so that when the L-shaped template 301 on the other side is pulled, the L-shaped template 301 on the front side moves forward simultaneously.

[0032] The detection mechanism includes a sliding column 603. The sliding column 603 is fixedly connected to the upper surface of the equipment platform 100 on the side far from the locking plate 403. The two ends of the sliding column 603 are fixedly connected to the equipment platform 100. The sliding column 603 is slidably connected to a tension control plate 602. A tension sensor 601 is provided between the tension control plate 602 and the L-shaped template 301 on the same side. The two ends of the tension sensor 601 are respectively fixedly connected to the tension control plate 602 and the L-shaped template 301 on the same side.

[0033] The slide post 603 is used to maintain the sliding stability of the tensile force control plate 602, the tensile force control plate 602 is used to connect the tensile force sensor 601, and the tensile force sensor 601 is used to test the tensile strength and shear strength.

[0034] The detection mechanism further includes a threaded rod 604. The rear end of the threaded rod 604 is rotatably connected to the tensile force control plate 602. A threaded plate 606 is threadedly connected to the middle of the threaded rod 604, and a handle 605 is fixedly connected to the front end of the threaded rod 604.

[0035] The threaded plate 606 converts the rotational motion into the axial motion of the threaded rod 604 through the threaded connection with the threaded rod 604, facilitating the pulling of the tensile force control plate 602 and the tensile force sensor 601. The handle 605 facilitates the manual control of the rotation of the threaded rod 604.

[0036] Working principle:

[0037] When detecting the shear strength of the potting adhesive, the potting adhesive is placed into the square bucket formed by the L-shaped template 301 and the side plate 302. After the potting adhesive solidifies, control the right telescopic rod 501 to extend and insert the U-shaped fork 502 into the top ends of the two L-shaped templates 301. The left telescopic rod 501 contracts, then insert the I-shaped column 402 into the locking hole 404 to the left to lock the left L-shaped template 301. The right L-shaped template 301 can slide back and forth. Manually rotate the handle 605 to drive the threaded rod 604 to rotate. Under the threaded action of the threaded plate 606, the threaded rod 604 moves forward. The threaded rod 604 pulls the tensile force sensor 601 through the tensile force control plate 602, and the tensile force sensor 601 pulls the right L-shaped template 301, causing the potting adhesives on both sides to generate shear force, and then the shear parameters can be measured.

[0038] When detecting the tensile strength of the potting adhesive, control the telescopic rod 501 to push the U-shaped fork 502 downward so that the front fork of the U-shaped fork 502 is inserted into the rear L-shaped template 301, and the rear fork of the U-shaped fork 502 is inserted into the locking column 503 to fix the rear L-shaped template 301 and the locking column 503. At the same time, move the I-shaped column 402 to the right so that the I-shaped column 402 is clamped to the right L-shaped template 301, ensuring that when the right L-shaped template 301 moves forward, it also pulls the left L-shaped template 301 forward. Then rotate the handle 605 to make the threaded rod 604 rotate. Under the threaded action of the threaded plate 606, the threaded rod 604 moves forward. The threaded rod 604 pulls the tensile force sensor 601 through the tensile force control plate 602, and the tensile force sensor 601 pulls the right L-shaped template 301. The two front L-shaped templates 301 move forward synchronously, and the side plate 302 and the stop strip 303 move forward synchronously, pulling the potting adhesive to be tested forward. Finally, the tensile parameters of the potting adhesive are detected by the tensile force sensor 601.
