Description

Technical Field

[0001] The invention relates to the technical field of road engineering test equipment, and in particular to a cold patch material cohesion tester. Background Art

[0002] Potholes are common diseases in highways of all levels in my country, affecting the performance, driving comfort, safety and aesthetics of the road surface. If not handled in time, the potholes will further expand and deepen with the action of vehicles, causing deep diseases and reducing the service life of the road surface. The pothole cold patching process has the advantages of simple equipment, no need for heating, convenient construction, and low pollution emissions. It is an excellent pothole repair method. Cold patch materials are widely favored because of their ready-to-use, fast traffic opening, and less impact from construction temperature and weather. Cohesion is a property that evaluates the adhesion between solvent-based cold patch particles and their non-looseness in low temperature environments. Although there are certain methods at present, there are relatively few recognized effective and simple special testing instruments. In addition, the existing testing instruments have complex structures and operations and are not convenient to use. Therefore, a cold patch material cohesion tester is needed.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0024] like Figure 1-3 As shown, a cold patch material cohesion tester includes a cabinet 1, a controller 2, a motor 3, a test chamber 4 and a balance 5. The controller 2 is embedded in the upper left corner of the front end of the cabinet 1. Guide rails 7 are respectively arranged on both sides of the middle part of the cabinet 1. Racks 8 are arranged on the guide rails 7. Gears 6 are respectively connected to the two ends of the motor 3. The gears 6 are meshed and connected with the racks 8 on the guide rails 7, so that the motor 3 can roll left and right along the guide rails 7. The test chamber 4 is connected to one end of the motor 3. The rolling of the motor 3 drives the test chamber 4 to roll. The balance 5 is arranged on the cabinet 1, and the balance 5 is independently arranged. The motor 3 and the balance 5 are respectively connected to the controller 2.

[0025] like Figure 2 As shown, a crossbeam is provided on one side of the guide rail 7 near the motor 3. An iron card is extended outward from the bottom of both ends of the body of the motor 3, and the iron card is attached to the lower part of the crossbeam of the guide rail 7, which can ensure that the motor can translate stably without self-rotation.

[0026] like Figure 2-3 As shown, the cabinet 1 is set as a rectangular iron frame for supporting and fixing other components. The controller 2 is set as a digital display controller, and the controller 2 is connected to the motor 3 to control the start and stop, speed, and direction of the motor 3, and then control the number of cycles, cycles, and direction of the test cabin 4. Among them, the number of cycles (the number of complete cycles / piece) × cycle (the time required for a complete cycle movement / s) = rolling time (seconds); the cycle refers to the time required for the test cabin to roll from the middle position to one side, then to the other side, and finally back to the middle position. By controlling the speed, cycle, number of cycles and rolling time of the motor 3 and the test cabin 4, when the controller 2 controls the motor 3 to start, the gear 6 on the motor 3 rolls on the rack 8 of the guide rail 7. Since the test cabin 4 is connected to one end of the motor 3, when the motor 3 rolls, the test cabin 4 also rolls with the motor 3, so the speed, direction and number of cycles of the test cabin 4 are the same as those of the motor 3.

[0027] In the embodiment of the present invention, the balance 5 is connected to the controller 2 via a signal line, and the sample dish of the balance 5 is detachable. The specimen is placed in the sample dish of the balance 5, and the controller 2 is pressed, and the controller 2 automatically weighs and records the mass (m) of the specimen, accurate to 0.1g. The controller 2 is connected to the balance 5, and is used to control the weighing of the balance 5, and automatically calculates and outputs the residual rate of the cold patch material according to the data obtained by the weighing of the balance.

[0028] The calculation formula of the residual rate is:

[0029] c=(1-m1 / m)×100%Formula (1)

[0030] In the formula: c is the residual rate of cohesion, %; m is the initial mass of the specimen, g; m1 is the mass of the cold patch material that falls into the balance sample dish, g.

[0031] The motor 3 automatically stops after reaching a predetermined number of cycles under the control of the controller 2, automatically reads the mass m1 of the cold patch material debris in the balance 5, and calculates and outputs the cohesive residual rate c of the cold patch material according to the following formula, accurate to 0.1%.

[0032] In an embodiment of the present invention, the center of one side of the test cabin 4 is connected to the motor 3. The test cabin 4 is in the shape of a round pancake, the inner wall diameter is set to 300 mm, the inner wall depth is set to 65 mm, and a hatch that can be opened and closed and has a sealing rubber ring is set on the front. The bottom wall of the test cabin 4 is provided with two hollow square notches, and the center angle of the notch width is set to 10°. By opening the door of the test cabin 4, the test piece is placed between the two hollow positions of the bottom wall of the test cabin 4. After the test piece is placed, the door of the test cabin 4 is closed, and the balance 5 is moved to the bottom of the test cabin 4, so that the cold patch material Marshall specimen gradually breaks with the rolling of the test cabin 4, and the cold patch material debris falls into the sample dish of the balance 5.

[0033] How to use the cold patch material cohesion tester

[0034] 1. Put 800g of cold patch material into the Marshall test mold, and place the type I, type II, and type III cold patch materials in an environmental insulation box with a temperature control of -10℃±0.5℃, 10℃±0.5℃, and 22℃±0.5℃ for 6 hours;

[0037] 4. Quickly open the test chamber door and place the test piece between the two hollow positions at the bottom of the test chamber;

[0038] 4. Close the cabin door and move the balance to the bottom of the test cabin;

[0040] 6. At the beginning of the test, the test chamber rolls left and right driven by the motor, and the cold patch material Marshall specimen gradually breaks up with the rolling of the test chamber, and the cold patch material debris falls into the balance sample dish;

[0041] 7. The motor stops automatically after reaching a predetermined number of cycles under the control of the controller, automatically reads the mass m1 of the cold patch material debris on the balance, and calculates and outputs the cohesive residual rate c of the cold patch material according to the following formula (1), with an accuracy of 0.1%.

[0042] c=(1-m1 / m)×100%Formula (1)

[0043] In the formula: c is the residual rate of cohesion, %; m is the initial mass of the specimen, g; m1 is the mass of the cold patch material that falls into the balance sample dish, g.
