The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0021] First Embodiment

[0022] Please refer to Figures 1 to 3 , where Figure 1 is a schematic structural diagram of the whole of the first embodiment,[[]] Figure 2 is a side view of the whole of the first embodiment,[[]] Figure 3 is Figure 2 Structural cross-sectional view taken along line A-A of...

[0023] The utility model provides a device for testing the heat deformation of marking paint, which comprises a box body 101, a box cover 102 and a testing module. The testing module includes a sleeve 103, a guide rod 104, an electric reciprocating lead screw 105, a hydraulic cylinder 105, a mounting bracket 107, a pressing wheel 108, an electric heating plate 110, a heat conduction testing plate 111 and a pressing unit. The pressing unit further includes two pressing plates 112, two sliding rods 113, a pressing plate 114, a driving motor 115, a cam 116, two reset springs 117 and two rubber pads 118. By the foregoing solution, the problems in the traditional testing of traffic marking paint are solved, including the need for professional testing equipment and personnel, the consumption of a large amount of manpower and time, and the complexity of the testing process.

[0024] For this specific embodiment, the box cover 102 is rotatably connected to the box body 101 and is located outside the box body 101. The testing module is arranged in the box body 101, and the traffic marking paint is tested in the box body 101 by using the testing module.

[0025] Among them, the electric reciprocating lead screw 105 is arranged inside the box body 101, the guide rod 104 is arranged above the electric reciprocating lead screw 105, the sleeve 103 is sleeved outside the electric reciprocating lead screw 105 and the guide rod 104 respectively, and is in threaded cooperation with the electric reciprocating lead screw 105. The hydraulic cylinder 105 is fixedly connected to the sleeve 103 and is located below the sleeve 103. The mounting bracket 107 is fixedly connected to the output end of the hydraulic cylinder 105. The extrusion wheel 108 is movably arranged inside the mounting bracket 107. The electric heating plate 110 is fixedly connected to the box body 101 and is located on the bottom wall of the box body 101. The heat conduction test plate 111 is arranged above the electric heating plate 110. The pressing unit is arranged on the box body 101. When testing the traffic marking paint, first spread the traffic marking paint to be tested evenly on the heat conduction test plate 111, then place the heat conduction test plate 111 in the box body 101 and locate it above the electric heating plate 110. Subsequently, fix it above the electric heating plate 110 through the pressing unit, close the box body 101 with the box cover 102, start the electric heating plate 110 to heat up. The high temperature will conduct to the surface of the heat conduction test plate 111, and use the electric heating plate 110 to simulate the high temperature environment. When the temperature on the surface of the heat conduction test plate 111 reaches the test temperature, then start the electric reciprocating lead screw 105 and the cylinder 202. The cylinder 202 controls the extrusion wheel 108 to contact the surface of the heat conduction test plate 111. The electric reciprocating lead screw 105 controls the extrusion wheel 108 to roll back and forth on the surface of the heat conduction test plate 111 and repeatedly rub against the detected traffic marking paint coating. At the same time, the cylinder 202 can control the pressure of the extrusion wheel 108 contacting the heat conduction test plate 111, so as to simulate the pressure caused by different vehicle operations on the traffic marking on the road, ensuring the accuracy of the detection. Through the above method, it is realized that it is convenient to test the traffic marking paint, greatly reducing the manpower and time, and the test process is very simple.

[0026] Secondly, the box body 101 has a cavity 109. Two of the pressing plates 112 are symmetrically arranged above the electric heating plate 110. Two of the sliding rods 113 are respectively fixedly connected to the corresponding pressing plates 112 and inserted into the cavity 109. The extrusion plate 114 is fixedly connected to both of the sliding rods 113 and is located within the cavity 109. The drive motor 115 is arranged within the cavity 109. The cam 116 is connected to the output end of the drive motor 115 and is located above the extrusion plate 114. Each of the return springs 117 is fixedly connected to the extrusion plate 114 and the box body 101 respectively. Place the heat conduction test plate 111 above the electric heating plate 110, and then start the drive motor 115 within the cavity 109. The drive motor 115 controls the rotation of the cam 116. The cam 116 pushes the extrusion plate 114 to move downward within the cavity 109. At the same time, the extrusion plate 114 drives the two sliding rods 113 to move downward within the cavity 109. The two return springs 117 are stretched as the extrusion plate 114 moves downward. The two pressing plates 112 will fix the heat conduction test plate 111 above the electric heating plate 110 to prevent the heat conduction test plate 111 from shifting during the test.

[0027] Meanwhile, two of the rubber pads 118 are respectively fixedly connected to the corresponding pressing plates 112 and are respectively located on the outer side walls of the pressing plates 112. By arranging the rubber pads 118 below the pressing plates 112, the rubber pads 118 can increase the friction between the pressing plates 112 and the heat conduction test plate 111, and can fix the heat conduction test plate 111 more stably within the box body 101.

[0028] When testing traffic marking paint, first apply the traffic marking paint to be tested evenly on the heat conduction test plate 111, then place the heat conduction test plate 111 in the box body 101 and above the electric heating plate 110. Subsequently, control the rotation of the cam 116 through the driving motor 115. The cam 116 pushes the extrusion plate 114 to move downward in the cavity 109. The extrusion plate 114 drives the two pressing plates 112 to move through the two sliding rods 113. The two pressing plates 112 will press the heat conduction test plate 111 tightly above the electric heating plate 110, which can prevent the heat conduction test plate 111 from shifting during the test. Close the box body 101 with the box cover 102 and start the electric heating plate 110 to heat up. The high temperature will be conducted to the surface of the heat conduction test plate 111, using the electric heating plate 110 to simulate a high-temperature environment. When the temperature on the surface of the heat conduction test plate 111 reaches the test temperature, then start the electric reciprocating screw rod 105 and the air cylinder 202. The air cylinder 202 controls the extrusion wheel 108 to contact the surface of the heat conduction test plate 111. The electric reciprocating screw rod 105 controls the extrusion wheel 108 to roll back and forth on the surface of the heat conduction test plate 111 and repeatedly rub against the detected traffic marking paint coating. At the same time, the air cylinder 202 can control the pressure of the extrusion wheel 108 contacting the heat conduction test plate 111, thereby simulating the pressure on the traffic marking caused by different vehicle operations on the road, ensuring the accuracy of the detection. Through the above method, it is realized that it is convenient to test traffic marking paint, greatly reducing manpower and time, and the test process is very simple.

Multiple mounting seats 203 are all fixedly connected to the lifting plate 201 and are all located below the lifting plate 201.

Then, the operator applies force to move the box body 101, and the multiple moving wheels 204 will roll on the ground.

[0034] The pull rod 205 is fixedly connected to the box body 101 and is located on the outer side wall of the box body 101. By arranging the pull rod 205 on the outer side of the box body 101, it is convenient to apply force to move the box body 101 by using the pull rod 205.

Then, the operator applies force to pull the pull rod 205, and the pull rod 205 drives the box body 101. At this time, the multiple moving wheels 204 will roll on the ground. After the movement is completed, start the cylinder 202 to control the lifting plate 201 and the moving wheels 204 to reset below the box body 101, and multiple legs below the box body 101 contact the ground.
