[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1-4As shown, a cold patch material durability testing equipment for laboratory use includes a base 1, a cold patch material forming platform 2 and a wear mechanism 3. The cold patch material forming platform 2 can be filled with cold patch material. The stirred and unformed cold patch material is filled on the cold patch material forming platform 2, and necessary trimming and smoothing are performed. After the cold patch material solidifies, a solid plane will be formed, that is, the plane to be tested. The wear mechanism 3 mainly includes a support component 310, a wear component 320 and a pressurizing component 330. The support component 310 is fixedly installed on the base 1. Its main function is to provide a basis for the installation and force application of the wear component 320 and the pressurizing component 330. The wear component 320 is installed on the support The support assembly 310 is inside the support assembly 310 and slides with the support assembly 310. It can move in a direction perpendicular to the plane to be measured, usually up and down. The working end of the wear assembly 320 abuts against the plane to be measured and is used to wear the surface of the plane to be measured, thereby facilitating the test personnel to perform wear tests. The mounting end of the pressure assembly 330 is fixedly connected to the support assembly 310, and its working end is fixedly connected to the wear assembly 320. The working end of the pressure assembly 330 has a tendency to move away from its own mounting end in a direction perpendicular to the plane to be measured. Through this movement tendency, pressure can be applied to the wear assembly 320, and the secondary pressure is transmitted to the working end below the wear assembly 320. Through the above technical solution, the utility model provides a comprehensive testing equipment for the compressive and wear resistance of the cold patch material after solidification and forming. The equipment can provide additional load to the wear component 320 through the cooperation of the pressurizing component 330 and the wear component 320, and can increase the pressure of the wear component 320 on the surface of the cold patch material after forming, thereby obtaining wear test data under high pressure. While conducting wear resistance tests, pressure resistance tests can also be performed. A variety of data can be obtained using one device, saving laboratory space and improving test efficiency.

[0034] To further improve the technical solution, the pressurizing component 330 includes multiple springs 331 and the same number of telescopic guide rods 332. The number of springs 331 is at least two, which are arranged vertically and the upper end of the spring 331 is mounted on the supporting component 310, which is equivalent to the mounting end of the spring 331, and the lower end of the spring 331 is mounted on the upper end of the wear component 320, which is equivalent to the working end of the spring 331. The spring 331 is always in a compressed state. Since the supporting component 310 is fixed and the wear component 320 has an adjustment that can slide up and down, the lower end of the spring 331 always has a tendency to move away from its upper end. Based on this, the spring 331 can squeeze the wear component 320 at its lower end so that it abuts against the surface of the plane to be measured and continuously provide downward pressure. The number of telescopic guide rods 332 corresponds one to one to the number of spring 331 columns, and the vertical The measuring plane is fixedly installed on the wear component 320. The spring 331 is cylindrical and is correspondingly sleeved on the outside of the telescopic guide rod 332. The inner side of the cylindrical spring 331 is close to the telescopic guide rod 332. The telescopic guide rod 332 is mainly used to guide the spring 331, so that the spring 331 moves strictly in the direction perpendicular to the plane to be measured, ensuring that the direction of the elastic potential energy of the spring 331 is always perpendicular to the plane to be measured, and no angle is generated with the plane to be measured. Through the further technical solution of the above technology, the utility model specifically defines the structure of the pressurizing component 330, and utilizes the spring 331 and the telescopic guide rod 332 to realize pressurization of the wear component 320. The spring 331 is used in a compressed state, which is beneficial to assist the working end of the wear component 320 to abut against the plane surface formed by the cold patch material and further improve the wear effect.

[0035] In order to further improve the technical solution, the pressurizing assembly 330 also includes an extrusion plate 333 and a hydraulic cylinder 334. The extrusion plate 333 is arranged parallel to the plane to be measured, fixedly connected to the upper ends of the multiple telescopic guide rods 332 and is in a sliding connection with the support assembly 310. The sliding direction is strictly perpendicular to the plane to be measured. The mounting end of the hydraulic cylinder 334 is fixedly connected to the support assembly 310, and its output end is perpendicular to the extrusion plate 333 and fixedly connected to the upper end of the extrusion plate 333. Under normal conditions, the output end of the hydraulic cylinder 334 applies pressure to the extrusion plate 333, and its size adapts to the elastic force generated by the spring 331 to prevent the upper end of the spring 331 from moving and ensure that the spring 331 is in a compressed state. When it is necessary to increase the pressure, the output pressure of the hydraulic cylinder 334 is increased. At this time, the output pressure of the hydraulic cylinder 334 is greater than the elastic force of the spring 331. The extrusion plate 333 acts on the spring 331, causing the spring 331 to be further compressed. The elastic force generated by the further compressed spring 331 will be released from its lower end, causing its lower end to tend to move further away from the upper end, and finally converted into the pressure of the wear component 320 on the plane to be measured. By further improving the above technical solution, the utility model uses the hydraulic cylinder 334 to cooperate with the extrusion plate 333 to apply an additional load to the spring 331, and then adds this part of the pressure to the wear component 320 through the action of the spring 331, which can adjust the pressure applied by the pressurizing component 330 to the wear component 320 as a whole. For the convenience of control, a pressure sensor can also be set accordingly to obtain an accurate pressure value, and then combined with the data obtained from the wear test, the test data under different pressures can be obtained, making the test work more rigorous and accurate.

[0036] To further improve the technical solution, the wear assembly 320 includes a wheel frame 321, an axle 322, at least two wheels 323 and a rotating motor. The two ends of the wheel frame 321 in the water direction are slidably connected to the support assembly 310 in the direction perpendicular to the plane to be measured. It is mainly used to install other structures of the wear assembly 320 and receive pressure from the pressurizing assembly 330. The axle 322 is arranged parallel to the plane to be measured and is rotatably connected to the lower end of the wheel frame 321. In order to ensure the balance of pressure transmitted by the wheel frame 321, the center of the line or surface formed by the axle 322 and the multiple springs 331 above is kept on the same line perpendicular to the plane to be measured. In this embodiment, there are two springs 331, so the axle 322 is located at the bottom and arranged between the two springs 331. In order to facilitate force transmission, the bottom of the wheel frame 321 can be changed into a triangular plate, and the axle 322 is located at the vertex of the triangle. The upper end face of the wheel frame 321 receives the pressure and transmits it to the wheel axle 322 below. The two wheels 323 are fixedly mounted on the wheel axle 322, and the two ends of the wheel axle 322 are respectively ensured to balance the forces. The casing of the rotating motor is located inside the wheel frame 321 and is fixedly connected to the wheel frame 321. Its motor shaft is transmission-connected to one end of the wheel axle 322. After starting the rotating motor, the wheel axle 322 is driven to rotate at high speed to perform high-speed friction on the surface to be measured. Through the above-mentioned further improvement of the technical solution, the utility model specifically defines the structure of the wear component 320, and uses the wheel frame 321 to receive the pressure of the pressurizing component 330 and transmit it to the wheel 323 below to increase the pressure on the surface of the wheel 323 and the solidified cold patch material. The rotating motor drives the wheel 323 to rotate, and performs high-speed friction on the surface to be measured formed by the cold patch material. Based on this, the wear resistance of the cold patch material is tested.

[0037] In order to further improve the technical solution, it also includes a wheel accessory 324. Specifically, a plurality of installation grooves are opened on the wheel 323 along its circumference, and a plurality of wheel accessories 324 can be detachably installed in the installation grooves. Compared with simply relying on the circumference of the wheel 323 to rotate and rub the surface to be measured formed by the cold patch material, the effect after installing the wheel accessory 324 will be significantly improved, and the wear effect will be significantly improved. Specifically, different wheel accessories 324 have different sizes, shapes and materials. For example, the wheel accessory 324 can be a spherical bump or a frosted strip, etc. Through the above-mentioned further improved technical solution, the utility model can utilize the replacement of different types of wheel accessories 324 to make the rotation have different friction effects on the surface to be measured formed by the cold patch material.

[0038] To further improve the technical solution, it also includes a lifting mechanism 4, which is also installed on the support assembly 310. The support assembly 310 specifically includes multiple support legs 311 and a mounting frame 312. The lower ends of the multiple support legs 311 are fixedly mounted on the base 1 by bolts. The mounting frame 312 is fixedly connected to the upper ends of the multiple support legs and supported by the support legs. On one side of the mounting frame 312, there is a mounting plate with a slide rail. The wear assembly 320, specifically the wheel frame 321 in the wear assembly 320, is installed in the mounting frame 312 and can slide up and down in a direction perpendicular to the plane to be measured through the slide rail. The lifting mechanism 4 is fixedly mounted on the top of the mounting frame 312, and its working end is connected to the wear assembly 320. After the working end of the lifting mechanism 4 is started, it can overcome the potential energy of the spring 331 and temporarily pull the wear assembly 320 away from the platform to be measured. Through the above-mentioned further improved technical solution, the utility model connects the wear assembly 320 as a whole to the mounting frame 312 by sliding, and then cooperates with the lifting mechanism 4 to lift the wear assembly 320, so as to facilitate the replacement of the cold patch material on the cold patch material forming platform 2 below for the next test.

[0039] To further improve the technical solution, the lifting mechanism 4 includes a slide rail 410 and a sling 420. Specifically, the slide rail 410 has two horizontally arranged and parallel to each other, and is fixed to the upper end of the mounting frame 312. The mounting end of the sling 420 is slidably connected to the slide rail 410 and can move horizontally on the slide rail 410. It has a movable working end, which can be a workpiece such as a hook or a clamp. The workpiece is connected to the wheel frame 321 in the wear assembly 320 and is lifted by overcoming the elastic force of the spring 331, driving the entire wear assembly 320 away from the cold patch material forming platform 2. Through the above-mentioned further improved technical solution, the utility model uses the sling 420 to lift the wear assembly 320 and allows the sling 420 to move on the slide rail 410. It can also adjust the effective position of the wear assembly 320 on the formed cold patch material plane, and can test multiple positions of the test platform formed by the cold patch material.

[0040] To further improve the technical solution, the cold patch material forming platform 2 includes a tray 210 and a mold 220. The tray 210 is installed on the upper end surface of the base 1; the outer periphery of the mold 220 is detachably connected to the tray 210, and the interior is used to fill the cold patch material. Specifically, the material of the mold 220 is rectangular in shape similar to the road surface. The cross-section and thickness of the mold 220 can also be set to simulate the pits on the road surface that need to be repaired. The stirred cold patch material is poured into the mold 220 and then spread flat. Wait for the cold patch material to completely solidify before testing. Through the above-mentioned further improved technical solution, the utility model uses the tray 210 to cooperate with the mold 220 to provide a space for solidification and molding, and the detachable mold 220 and the cold patch material can be directly removed and replaced with a new mold 220 after solidification.

[0041] To further improve the technical solution, a tray drive mechanism 5 is also included. The tray drive mechanism 5 is mounted on the base 1 to drive the tray 210 to move horizontally. The specific tray drive mechanism 5 can be in various forms. In this embodiment, a motor is used in conjunction with a lead screw and a lead screw slider. The tray 210 is mounted on the lead screw slider. After the motor is started, the lead screw can drive the tray 210 on the lead screw slider to move. Through the above-mentioned further improved technical solution, the utility model can give the cold patch material forming platform 2 a certain degree of freedom by providing the tray drive mechanism 5. While the wear assembly 320 is undergoing wear testing, the tray drive mechanism 5 can be used to adjust the position of the cold patch material formed above, so that wear testing can be performed in multiple locations.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
