Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete pressure testing technology, specifically to an asphalt concrete pressure testing device. Background Technology

[0002] Asphalt concrete pressure testing refers to measuring the strength and load-bearing capacity of asphalt concrete after curing. Specialized pressure testing equipment is used to ensure the quality and safety of asphalt concrete structures. The testing equipment detects the compressive strength of the material by applying pressure. Concrete and asphalt are commonly used building materials with different properties and applications.

[0003] Currently, pressure testing equipment still has some shortcomings, such as the difficulty for workers to clean up these concrete debris:

[0004] To overcome the difficulty of cleaning up these concrete debris, a Chinese patent (publication number: CN220019223U) discloses a concrete pressure testing device. By setting up a protective net and telescopic springs, the protective net can be buffered, protecting both the net and the relevant personnel. By setting up push rods, moving plates and discharge hoppers, the device can clean up the concrete debris inside the testing chamber.

[0005] However, the pressure testing equipment currently in use still has certain shortcomings. The above document achieves the purpose of cleaning concrete debris inside the testing box by setting push rods, moving plates, and discharge hoppers. Although push rods are effective at cleaning debris, they may not be able to clean some smaller debris. Secondly, if the debris is large, it will be heavy, and it will be difficult to push the moving plate with push rods. Furthermore, the dust generated during the debris cleaning process will be scattered everywhere, which can easily cause machine failure over time. Therefore, the existing structure needs to be improved. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0031] like Figures 1-6 The present invention provides the following technical solution to address the problem that pressure testing equipment is inconvenient to clean concrete aggregate, thus affecting testing efficiency: A rotating mechanism is disclosed.

[0032] The device includes a housing 1, a controller 2 mounted on the front of the housing 1, a pressure device 3 mounted on the upper inner surface of the housing 1, a support platform 4 fixed on the lower inner surface of the housing 1, a fixing frame 101 fixed inside the housing 1 near the support platform 4, first sliding grooves 102 symmetrically formed on the upper surface of the fixing frame 101, a threaded rod 103 rotatably connected inside the first sliding groove 102, a first slider 104 threadedly connected to the surface of the threaded rod 103, and the first slider 104 sliding through the first sliding groove 102. A rotating mechanism to improve the cleaning efficiency of the detection equipment is provided inside the fixing frame 101. A diverter plate 116 is mounted on the back of the housing 1, a water tank 117 is connected to the left side of the housing 1, and a dust-reducing mechanism to reduce dust diffusion is provided on the outer side of the housing 1. The rotating mechanism includes a second sliding... The second slide groove 105 is symmetrically opened on the bottom of the support platform 4. A second slider 106 slides through the second slide groove 105. A rotating rod 107 is rotatably connected between the second slider 106 and the first slider 104. A worm gear 108 is fixed to the right end of the threaded rod 103. A double-headed worm 109 is meshed with the side of the worm gear 108. The double-headed worm 109 is rotated by a motor inside the rotating groove 110. The rotating groove 110 is opened inside the fixed frame 101. Rotating grooves 111 are opened on both sides inside the housing 1. A first fixing block 112 slides through the rotating groove 111. The first fixing block 112 is fixed to both sides of the support platform 4. A second fixing block 113 is fixed on both sides of the support platform 4 away from the first fixing block 112. The fixed block 113 rotates inside the housing 1. A through-hole 114 is provided on the back of the housing 1. Baffles 115 are symmetrically fixed on both sides of the support platform 4. A collection bag 122 is connected to the back of the support platform 4 near the through-hole 114. When the testing equipment is in use, the concrete to be tested is placed on the upper surface of the support platform 4. The machine is started by the controller 2. When the machine is running, the pressure device 3 can drive the pressure plate to press the concrete. By continuously increasing the pressure, the concrete is broken, and the limit of the concrete stress can be calculated. After the concrete is broken by the pressure, it will break and disperse on the upper surface of the support platform 4. When the pressure device 3 returns to its original position and retracts, it drives the double-headed worm gear 109 to rotate through the motor. When the double-headed worm gear 109 rotates, it can drive the second slide groove 105 to mesh and rotate. When the second slide groove 105 engages and rotates, it can drive the threaded rod 103 to rotate. When the threaded rod 103 rotates, it can rotate through the first slide groove 102. When the threaded rod 103 rotates, it can drive the first slider 104 to slide thread-like. When the first slider 104 slides thread-like, it can slide through the first slide groove 102. When the first slider 104 slides, it can push the rotating rod 107 to rotate. When the rotating rod 107 rotates, it can push the second slider 106 to move. When the second slider 106 moves, it can slide through the second slide groove 105. At the same time, the second slider 106 can squeeze the second slide groove 105. When the second slide groove 105 is squeezed, it can push the support platform 4 to rotate. When the support platform 4 rotates, it can rotate inside the housing 1 through the second fixing block 113.Simultaneously, the support platform 4 can drive the first fixed block 112 to rotate. When the first fixed block 112 rotates, it can slide through the rotating groove 111. The support platform 4 will tilt when rotating, allowing the gravel on its surface to slide through the through-hole 114 into the collection bag 122. At the same time, the baffle 115 prevents the gravel from falling from the side during its descent. After falling into the through-hole 114, the gravel can be collected, improving the cleaning efficiency of the concrete pressure testing equipment. Example 2:

[0033] like Figure 2 and Figure 7 The present invention provides the following technical solution to address the problem of dust scattering during the cleaning of crushed stone in pressure testing equipment: A dust suppression mechanism is disclosed.

[0034] The dust suppression mechanism includes a press pump 118, which is installed on the left side of the housing 1. A first connecting pipe 119 connects the inlet of the press pump 118 to the outlet of the water tank 117, and a second connecting pipe 121 connects the outlet of the press pump 118 to the diversion plate 116. A piston rod 120 is connected through the top of the press pump 118, and a spring connects the piston rod 120 to the press pump 118. When the dust is collected into the collection bag 122 by the detection equipment, the piston rod 120 is pressed. When the piston rod 120 is pressed, it can slide into the press pump 118. At the same time, the piston rod 120 can compress the spring and release the piston rod. Under the action of the spring force, the piston rod 120 can be pushed to reset. In this way, the piston rod 120 can be pressed repeatedly. Pressing the piston rod 120 can expel the gas inside the press pump 118. The pressure difference generated by the expelled gas can transport the water inside the water tank 117 to the press pump 118 through the first connecting pipe 119. The press pump 118 then transports the water to the diversion plate 116 through the second connecting pipe 121 for diversion. The diverted water can be sprayed out in a mist form through the nozzle at the bottom of the diversion plate 116. After the water mist is sprayed out, it can reduce the spread of gravel and dust, improve the processing environment, and improve construction safety. Example 3:

[0035] like Figure 1 and Figure 8 The present invention provides the following technical solution to address the problem that pressure testing equipment is inconvenient to block the detected gravel: A protective mechanism is disclosed.

[0036] The pressure device 3 is equipped with a protective mechanism to prevent flying debris. This mechanism includes a rubber cylinder 301, which is movably connected to the surface of the pressure device 3. A connecting strip 302 is attached to the outside of the rubber cylinder 301. The connecting strip 302 and the side of the rubber cylinder 301 are connected by a male and female fastener, respectively. Before using the pressure testing equipment, the rubber cylinder 301 is manually pried open. The rubber cylinder 301 is then secured to the surface of the pressure device 3 through the opening. After securing, the rubber cylinder 301 is pressed down. Due to its material, the rubber cylinder 301 can be pressed into a cylindrical shape to wrap around the surface of the pressure device 3. At this point, pushing... The connecting strip 302 can rotate on the surface of the rubber cylinder 301. When the male buckle of the connecting strip 302 moves to the side of the female buckle of the rubber cylinder 301, it can be pressed to connect. The male and female buckles can be positioned when connected. Positioning can prevent the rubber cylinder 301 from popping open directly due to its own material. After the rubber cylinder 301 is connected to the surface of the pressure device 3, when the pressure device 3 detects the concrete pressure, the rubber cylinder 301 can be placed on the surface of the concrete sample. When concrete debris is splashed, it can be blocked by the rubber cylinder 301, thereby preventing debris from splashing and improving the safety of the operator when using the equipment.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
