Technical Field
[0001] The utility model relates to the technical field of quality detection, in particular to a portable construction engineering quality detection device. Background Art
[0002] The portable construction engineering quality inspection device is a portable device designed for construction engineering quality inspection. It mainly includes 1: a three-dimensional digital rebound tester, which is used to measure the compressive strength of concrete. Through the rebound measurement technology, the hardness of the concrete surface can be tested non-destructively, so as to deduce the compressive strength of the concrete. The instrument has the advantages of digital display, easy operation, and fast testing speed. 2: Carbonation depth tester, the carbonation depth tester is used to measure the depth of the carbonized layer on the concrete surface. The carbonization depth is one of the important indicators for evaluating the durability of concrete. The instrument determines the carbonization depth by measuring the hardness difference between the carbonized layer and the uncarbonized layer. 3: Laser rangefinder, the laser rangefinder is used to measure the size and distance of buildings or components. The instrument uses laser ranging technology to quickly and accurately obtain the distance data of the target object. It is suitable for a variety of measurement scenarios in construction projects and other different equipment. These devices can monitor various aspects of the quality of construction projects respectively;
[0003] However, the one-piece digital rebound test portable construction engineering quality inspection device has the problem that when it is necessary to inspect the concrete to be tested at a high place, the operator needs to climb up to the high place for inspection, which poses a safety hazard. The patent number in the prior art is CN218823559U, and its name is an integrated digital rebound tester. The operator rotates the handle bar, the handle bar drives the turntable to rotate, the turntable drives the round rod to rotate, the round rod drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, the first bevel gear drives the screw rod to rotate, the screw rod drives the nut to move upward, and under the restriction of the L-shaped rod, the nut drives the second connecting rod to move upward, thereby driving the rebound body and the digital display instrument to move upward, so as to detect concrete at a higher place, thereby solving the above problem.
[0004] However, when using the digital rebound tester to test the wall, it is necessary to hold the digital rebound tester with one hand and support the digital rebound tester with the other hand, then aim the elastic detection head installed on the outer surface of the digital rebound tester at the wall, and then push the digital rebound tester forward with the hand supporting the digital rebound tester until the elastic detection head is completely pushed into the interior of the digital rebound tester and the front end surface of the digital rebound tester contacts the wall, and then the hardness of the current wall can be known by observing the digital display screen on the outer surface of the digital rebound tester. However, in order to be able to test high walls without using a ladder, the above-mentioned integrated digital rebound tester is connected to a telescopic rod at the lower end surface of the digital rebound tester to test the high wall. However, since the digital rebound tester and the inspector are connected only by a telescopic rod, it is difficult for the inspector to exert force on the digital rebound tester. In order to ensure that the elastic detection head with elasticity installed on the front end surface of the digital rebound tester can completely enter the interior of the digital rebound tester due to the external force, during the inspection, the wall can only be inspected by swinging a hammer. When the inspection is carried out by swinging a hammer, the elastic detection head and the front end surface of the digital rebound tester will have a more violent collision with the wall, which may cause damage to both; therefore, it does not meet the existing needs, and we propose a portable construction engineering quality inspection device.

However, in order to be able to inspect a high place without using a ladder, the above-mentioned integrated digital rebound tester In order to detect the wall, a telescopic rod is connected to the lower end face of the digital rebound tester to detect the high wall. However, since the digital rebound tester and the inspector are connected only by a telescopic rod, it is difficult for the inspector to act on the digital rebound tester. In order to ensure that the elastic detection head with elasticity installed on the front end face of the digital rebound tester can completely enter the interior of the digital rebound tester due to its external force, when conducting the inspection, only the hammer-swinging method can be used to detect the wall. When the hammer-swinging method is used for inspection, the elastic detection head and the front end face of the digital rebound tester will produce a more violent collision with the wall, which may cause damage to both.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] The integrated digital display rebound tester 6 (model HT20-D), stepper motor 10 (model 35BYJ46) and threaded rod 11 (model M16) mentioned in the utility model can be purchased from the market or obtained by private customization.
[0024] See also Figures 1 to 4 The utility model provides an embodiment: a portable construction engineering quality detection device, comprising a square metal shell 1, an electric lifting platform 2 is fixedly installed on the upper end surface of the square metal shell 1, a mounting platform 3 is fixedly installed on the upper end surface of the electric lifting platform 2, and a horizontal bar cylinder 4 is fixedly installed on one side of the upper end surface of the mounting platform 3;
[0025] A digital rebound tester clamping platform 5 is fixedly mounted on the other side of the upper end surface of the mounting platform 3, and the piston rod of the horizontal bar cylinder 4 is located in the middle position behind the digital rebound tester clamping platform 5, and an integrated digital rebound tester 6 is clamped inside the digital rebound tester clamping platform 5.
[0026] A metal cover plate located on the outer surface of the square metal shell 1 is provided on one side of the stepper motor 10, and the stepper motor 10 and the metal cover plate are fixed by screws. An elastic detection head is installed in the middle position of the front end surface of the integrated digital rebound tester 6, and a digital display screen is fixedly installed in the middle position of the upper end surface of the integrated digital rebound tester 6. When in use, the square metal shell 1 is placed in the corresponding position, and then the power supply is connected. The electric lifting platform 2 is started to move the mounting platform 3 installed on the upper end surface of the electric lifting platform 2 and the integrated digital rebound tester 6 indirectly connected to the mounting platform 3 upward. When the integrated digital rebound tester 6 moves to the corresponding height, the integrated digital rebound tester 6 is moved to the corresponding height by The single-bar cylinder 4 can push the integrated digital rebound tester 6 forward, so that the elastic monitoring head installed on the outer surface of the integrated digital rebound tester 6 can contact the wall surface, and as the digital rebound tester 6 moves, the elastic monitoring head will be gradually pushed into the interior of the integrated digital rebound tester 6 until the front end surface of the integrated digital rebound tester 6 fits the wall surface. The above technical solution can prevent the integrated digital rebound tester 6 and the elastic monitoring head installed on the front end surface of the integrated digital rebound tester 6 from having a violent collision with the wall surface when detecting a high wall surface, thereby protecting the integrated digital rebound tester 6;
[0027] When the front end surface of the integrated digital rebound tester 6 contacts the wall, the electric lifting platform 2 is started to move the integrated digital rebound tester 6 back to the original height, and then the hardness value of the high wall can be obtained by observing the digital display screen located on the outer surface of the digital rebound tester.
[0028] A stepper motor 10 is fixedly installed on the lower side of the inside of the square metal shell 1, and the output shaft of the stepper motor 10 is connected to the threaded rod 11 through a coupling; when the square metal shell 1 is placed on the ground, the two adsorption heads 16 located on the lower end surface of the square metal shell 1 will also contact the ground. Before using the integrated digital rebound tester 6 to detect the high wall, start the stepper motor 10 first, and the stepper motor 10 can drive the threaded rod 11 connected thereto to rotate.
[0029] A lifting plate 12 is provided below the stepper motor 10, and a threaded rod 11 vertically penetrates the lifting plate 12, and the threaded rod 11 and the lifting plate 12 are connected by a threaded structure; a metal column 15 is provided on both sides below the lifting plate 12, and an adsorption head 16 is fixedly provided on the lower end surface of the metal column 15, and a piston groove 17 is provided in the middle position of the lower end surface of the adsorption head 16 and extends to the inside of the metal column 15 by penetrating the adsorption head 16; a piston head 14 is provided on the lower side of the piston groove 17 and fits with its inner wall, and a connecting rod 13 is fixedly connected to the middle position of the upper end surface of the piston head 14, and the upper end surface of the connecting rod 13 is fixed to the lifting plate 12; since the two sides of the lower end surface of the lifting plate 12 are respectively fixed to the two piston heads 14 by two connecting rods 13, the lifting plate 12 itself cannot rotate. When the connected threaded rod 11 rotates, the lifting plate 12, which is connected to it by a thread but cannot rotate by itself, will move up and down under the transmission of the threaded structure. At this time, the lifting plate 12 is moved upward. During the upward movement of the lifting plate 12, the piston head 14 connected to it by the connecting rod 13 will move upward inside the piston groove 17. As the piston head 14 rises, the air inside the piston groove 17 that penetrates the adsorption head 16 can be extracted through the piston head 14, making it hollow, so as to fix the square metal shell 1 on the current ground. The above technical solution can prevent the square metal shell 1 from moving backward at its original position due to the pushing force of the single-bar cylinder 4 when the integrated digital rebound instrument 6 is pushed forward by the single-bar cylinder 4, thereby improving the stability of the square metal shell 1.
[0030] A metal rod 7 is provided below the digital rebound test clamping platform 5, and a reset spring 8 is sleeved on the outer surface of the metal rod 7. One end of the reset spring 8 is connected to a metal sleeve 9 that is movable sleeved on the outer surface of the metal rod 7, and the metal sleeve 9 is fixed to the digital rebound test clamping platform 5 on the surface facing the digital rebound test clamping platform 5; when the integrated digital rebound test 6 contacts the wall, before the integrated digital rebound test 6 is moved downward, the piston rod of the horizontal bar cylinder 4 is first retracted, and the digital rebound test clamping platform 5 is pushed forward by the horizontal bar cylinder 4. The metal sleeve 9 will also move forward. When the metal sleeve 9 moves forward, it will squeeze the return spring 8. When the piston rod of the horizontal bar cylinder 4 is recovered, the reaction force of the squeezed return spring 8 can gradually push the digital rebound tester clamping table 5 and the integrated digital rebound tester 6 back to their original positions. The above technical solution can prevent the integrated digital rebound tester 6 or the front end surface of the elastic detection rod from causing friction with the wall when the integrated digital rebound tester 6 is moved downward, thereby preventing damage to the wall.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
