Description

Technical Field

[0002] C140 concrete is a high-strength concrete material, widely used in modern construction and civil engineering. C140 concrete has high compressive strength and can withstand large loads. It is suitable for high-rise buildings, bridges and other projects. Rebound hammers are used when testing the strength of concrete. The full name of rebound hammer is concrete compressive strength rebound tester. It is an instrument used for non-destructive testing of the compressive strength of concrete structural members. It indirectly evaluates its compressive strength by measuring the hardness of the concrete surface. In the strength testing process of C140 concrete, the use of rebound hammer is an important link, because it can provide a fast and non-destructive testing method to help engineering and technical personnel understand the actual strength of concrete.

[0003] When using the existing rebound tester, the user needs to operate it manually back and forth, which is very troublesome. It is necessary to repeat the test many times to comprehensively average the value, and the operation amount is very large. The existing rebound tester cannot be operated without the user's hands, and cannot automatically perform the strength rebound test, which increases the user's operation steps and test time. It is not convenient for the user to free his hands for more convenient value recording, and it is not convenient to fix the rebound tester on the wall to automatically perform strength testing.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing rebound hammers on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0019] 1. The present invention provides a positioning unit.

When testing, the user only needs to place and fix the outer frame on the wall to start the test.

When the user uses the outer frame and the rebound tester to test the concrete strength, the air between the suction cup and the wall is sucked away by the suction cup and the vacuum pump to form a negative pressure state. Due to the pressure difference, the suction cup is tightly adsorbed on the concrete wall. This adsorption force can ensure that the suction cup remains stable on the vertical or inclined wall, so that the outer frame is fixed on the wall and is not easy to fall off.

The top of the limiting plate 2121 is fixedly connected with an extension plate 2125, and the surface of the L-shaped plate 2119 is fixedly connected with a fixing ring 2126. The inner wall of the fixing ring 2126 is fixedly connected with a second motor 2127, and the output of the second motor 2127 is fixedly connected to the inner wall of the fixing ring 2126.

By setting the connecting column 2114 and the sliding block 2115, the positioning block 2107 and the fixed block 2118 can be connected. When the fixed block 2118 moves, the sliding block 2115 and the positioning block 2107 can be driven to move, and the sliding block 2115 slides on the inner wall of the mobile box 2105 , which can make its movement more stable and play a guiding role. By setting the L-shaped plate 2119, the square plate 2120 can be driven to move through the connection between the L-shaped plate 2119 and the fixed block 2118. By setting the limiting plate 2121, the user can adjust the position of the extension plate 2125 and the extension plate 2130, which can meet the installation of rebound testers 4 of different lengths and sizes, and is more convenient and more adaptable. By setting the fixing ring 2126, the position of the second motor 2127 can be fixed, making it more stable during operation.

[0040] The inner wall of the extension plate 2130 is provided with a sliding groove 2131, and the inner wall of the extension plate 2130 is slidably connected to a moving column 2132, and a slider 2133 is fixedly connected to the surface of the moving column 2132. There are two sliders 2133, and the surfaces of the two sliders 2133 are in contact with the inner wall of the sliding groove 2131. The bottom of the moving column 2132 is fixedly connected to a clamping plate 2134, and the top of the clamping plate 2134 is fixedly connected to a third motor 2135. The output end of the third motor 2135 is fixedly connected to the The second gear 2141 is connected to the bottom of the extension plate 2130, and the second gear plate 2136 is fixedly connected to the second gear 2141. The inner wall of the clamping plate 2134 is fixedly connected to a rubber pad 2137. The inner wall of the clamping plate 2134 is threadedly connected to a second threaded button 2138.

The surface of the rubber pad 2137 and the top plate 2139 The surfaces of the two plates 2132 and 2133 are in contact with the surfaces of the rebound tester 4 respectively. The rebound tester 4 is movably connected to the surface of the clamping plate 2134 through the rubber pad 2137 and the top plate 2139. By setting the sliding groove 2131, when the slider 2133 fixedly connected to the moving column 2132 slides on the inner wall of the sliding groove 2131, the movement of the moving column 2132 can be more stable and play a guiding role. By setting the clamping plate 2134, the user can install the rebound tester 4 on the clamping plate 2134, which is convenient for the user. To test the strength of C140 concrete, the position of the top plate 2139 can be moved up and down by setting the second threaded button 2138. When the top plate 2139 contacts the rebound test hammer 4, the second threaded button 2138 is continuously rotated to firmly fix the rebound test hammer 4 in the clamping plate 2134. The threaded setting allows the top plate 2139 to move upward. Continuous rotation applies greater pressure to the top plate 2139, and the rebound test hammer 4 is fixed by friction to ensure that it does not fall off during testing.

[0041] The specific implementation of this embodiment is as follows: when the user uses the rebound test hammer 4 to perform strength testing on C140 concrete, the user places the outer frame 1 on the concrete wall to be tested, and the user first places the rebound test hammer 4 in the clamping plate 2134, and manually rotates the second threaded button 2138 to allow the top plate 2139 to continue to move upward until it supports the rebound test hammer 4 and cannot continue to rotate. The top plate 2139 and the rubber pad 2137 are fully in contact with the rebound test hammer 4, and the rebound test hammer 4 can be installed and fixed on the clamping plate 2134. At this time, the user manually rotates the first threaded button 2124 to allow one end of the first threaded button 2124 to separate from the surface of the square plate 2120, thereby releasing the limit on the limit plate 2121, and setting the long rod 2122 and the The first spring 2123 can make the limit plate 2121 more stable when moving. The user can drive the extension plate 2125 and the extension plate 2130 to move by adjusting the movable limit plate 2121, and then the rebound tester 4 can be moved. After the detection head of the rebound tester 4 contacts the wall, the detection head of the rebound tester 4 extends. At this time, the user adjusts the movable limit plate 2121 to make the detection head of the rebound tester 4 have a certain distance from the wall, which is convenient for subsequent strength detection. After the position adjustment is completed, the user manually rotates the first threaded button 2124, and one end of the first threaded button 2124 is in close contact with the square plate 2120. By increasing the friction between the two, the limit plate 2121 can be limited. Then the user controls the opening and closing of the limit plate 2121 through the outside. The third motor 2135 is started, and the third motor 2135 is powered by the battery 2140. The output end of the third motor 2135 drives the second gear 2141 to rotate. The rotation of the second gear 2141 can make the movable column 2132 and the clamping plate 2134 move by meshing with the second tooth plate 2136. When the clamping plate 2134 moves, it can drive the rebound instrument 4 to move, so that the rebound instrument 4 can approach the wall and perform detection. After the rebound of the rebound instrument 4 is completed, the third motor 2135 is started to reverse, and the movable column 2132 and the clamping plate 2134 are reset by rotating the second gear 2141, so that the rebound instrument 4 can be reset and prepare for the detection of the next position. After the detection of the first position is completed, the user can The second motor 2127 is started by an external control switch, and the second motor 2127 is powered by the battery 2140. The output end of the second motor 2127 drives the first gear 2128 to rotate. The rotation of the first gear 2128 can be moved by meshing with the first tooth plate 2129. The movement of the second motor 2127 can drive the L-shaped plate 2119 to move through the fixing ring 2126. When the L-shaped plate 2119 moves, it can drive the square plate 2120 and the fixing block 2118 to move. When the fixing block 2118 moves, it can drive the positioning block 2107 to move through the connecting column 2114 and the sliding block 2115. When the positioning block 2107 moves, it can drive the rotating plate 2108 and the card wheel 2109 to move.Since the slope 2112 on the rotating plate 2108 is pressed by the spring piece 2111 set on the inner wall of the fixed column 2110, a downward pressure can be applied to the rotating plate 2108, and the clamping wheel 2109 can be pressed into the inclined groove 2106. At this time, the second motor 2127 stops outputting, and the rebound tester 4 can be driven to the second detection position. At the same time, the clamping wheel 2109 is pressed into the inclined groove 2106 to limit and fix the positioning block 2107, so as to prevent the positioning block 2107 from moving when the second motor 2127 stops running. When the four horizontal detection positions have been detected, the second motor 2127 drives the fixed The positioning block 2107 moves forward a little more, allowing the card wheel 2109 to contact the first inclined block 2116. At this time, the rotating plate 2108 is squeezed and rotates, causing the spring piece 2111 to enter the notch groove 2113. At this time, the spring piece 2111 can hook the rotating plate 2108 and limit it. The position of the card wheel 2109 is now in contact with the upper surface of the inclined groove 2106. At this time, the second motor 2127 can drive the positioning block 2107 to reset. When it is reset to the starting position, it continues to move forward a little distance to allow the card wheel 2109 to contact the second inclined block 2117. Due to the squeezing, the rotating plate 2108 can be given 108 downward pressure, at this time, the spring piece 2111 will be separated from the notch groove 2113 and re-contact the slope 2112, releasing the limit fixation of the spring piece 2111 on the rotating plate 2108.
