Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to an automatic pressurized concrete detection rebound tester. Background Art
[0002] Concrete is one of the main raw materials for modern buildings. The most common way to use concrete is to form it through pouring, and then to complete the main frame of the building. At the same time, in order to ensure the quality of the building, concrete needs to be tested during the production process and after pouring. For example, after the concrete is poured, a concrete rebound tester is needed to test its impact resistance and other capabilities;
[0003] When the existing concrete inspection and rebound test hammer is used, the staff generally holds the outer protection part and makes the top column part fully fit the concrete casting, and then squeezes and slides the outer protection part to the outside of the top column. After squeezing to the limit position, the hammer part inside the outer protection part hammers the tail of the top column part and records the rebound distance of the hammer part, thereby realizing the inspection task of the concrete. However, during the operation, it is often necessary to inspect multiple points for a concrete casting, so that the staff needs to perform the squeezing task frequently. In addition, the elastic part inside the detector has a high elastic force, and a single squeezing task is more laborious. Frequent implementation of this operation greatly increases the workload of the staff. Utility Model Content
[0004] The utility model aims to provide an automatic pressurized concrete testing hammer, which solves the above-mentioned problems by adding a part that automatically applies pressure.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] An automatic pressurized concrete testing rebound tester, comprising a rebound tester body,
[0007] A mounting groove is provided at the top of the outer side wall of the rebound tester body, and a rack is installed at the bottom of the mounting groove.

[0009] As a further solution of the utility model: handles are installed at both ends of the installation plate, and the outer walls of the handles are provided with anti-slip patterns.

[0011] As a further solution of the utility model: the transverse central axis of the movable block is parallel to the central axis of the mounting tube, and the movable block and the mounting tube are slidably connected.
[0012] As a further solution of the utility model: the driving assembly includes a connecting plate, which is installed on the top of the mounting plate close to the rebound instrument body, and an open bin is installed on the side of the connecting plate close to the rebound instrument body, a servo motor is installed at one end inside the open bin, and the output end of the servo motor is connected to an output shaft, and a gear is installed on the outside of the output shaft.

Once the top column is not fully in close contact with the concrete member, one or more groups of movable blocks will not be squeezed into the corresponding mounting tubes, and the warning lights will not all be lit. Therefore, during the operation, the operator can ensure that the top column is fully in close contact with the concrete member, thereby ensuring the accuracy of the detection.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example 1
[0026] See also Figure 1-Figure 4 As shown, the utility model is an automatic pressurized concrete testing rebound tester, comprising a rebound tester body 1, and the rebound tester body 1 is the same as the existing concrete rebound testing equipment;
[0027] like Figure 1 and Figure 4 As shown, a mounting groove 2 is provided at the top of the outer wall of the rebound tester body 1, and a rack 3 is installed at the bottom of the mounting groove 2, a top column 4 is provided at one end of the rebound tester body 1, and a mounting plate 5 is installed on the outer side of the top column 4, three groups of prompt lights 7 are evenly installed on the side of the mounting plate 5 close to the rebound tester body 1, and a controller assembly 8 is installed on one end of the mounting plate 5 close to the side of the rebound tester body 1, and handles 6 are installed at both ends of the mounting plate 5, and the outer wall of the handle 6 is provided with anti-slip grooves. During operation, the staff can hold the device by the handle 6 for use;
[0028] like Figure 2 and Figure 4As shown, a driving assembly for driving the rebound tester body 1 to move is arranged on the mounting plate 5, and the driving assembly includes a connecting plate 13, and the connecting plate 13 is mounted on the top of the mounting plate 5 close to the rebound tester body 1. An opening bin 14 is mounted on the side of the connecting plate 13 close to the rebound tester body 1, and a servo motor 15 is mounted on one end of the opening bin 14, and an output shaft 16 is connected to the output end of the servo motor 15, and a gear 17 is mounted on the outer side of the output shaft 16, and the central axis of the output shaft 16 coincides with the central axis of the gear 17, and the output shaft 16 is aligned with the central axis of the gear 17. The opening chamber 14 is rotatably connected, the gear 17 extends to the inside of the mounting groove 2, and the gear 17 is meshed with the rack 3, so that when the servo motor 15 drives the output shaft 16 and the gear 17 to rotate, the rebound tester body 1 can move toward the mounting plate 5, thereby cooperating with the top column 4 to complete the pressurization operation. At the same time, the rebound tester body 1 and the servo motor 15 are electrically connected to the controller assembly 8 respectively, so that the staff can control the servo motor 15 and the rebound tester body 1 through the controller assembly 8 while holding the handle 6;
[0029] Example 2
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, three groups of mounting tubes 9 are evenly installed on one side of the mounting plate 5 away from the rebound tester body 1, a squeeze button 10 is installed on the side of the mounting tube 9 close to the rebound tester body 1, and the squeeze button 10 is electrically connected to the corresponding prompt light 7, a movable block 11 is arranged inside the mounting tube 9, and a spring 12 is connected between the movable block 11 and the mounting tube 9, the transverse central axis of the movable block 11 is parallel to the central axis of the mounting tube 9, and the movable block 11 is slidably connected to the mounting tube 9, so that when the staff puts the top column 4 against the detected surface of the concrete member and keeps it in full vertical fit, Multiple groups of installation tubes 9 can also maintain contact with the surface, so multiple groups of movable blocks 11 can be squeezed into the corresponding installation tubes 9 and further squeeze the squeezing buttons 10, so that multiple groups of warning lights 7 light up at the same time, prompting the staff to start subsequent operations at this time. Once the top column 4 is not completely perpendicular to the concrete surface to be inspected and fully fits, there will be one or more groups of movable blocks 11 that are not completely squeezed into the corresponding installation tubes 9. At this time, multiple groups of warning lights 7 are not lit at the same time, thereby prompting the staff to make timely adjustments to ensure the accuracy of the test results.
[0031] Working principle of the utility model: the device is powered by an external power supply or a battery. When in use, hold the two groups of handles 6 and keep the end of the top column 4 fully vertical and in contact with the concrete surface to be inspected. At this time, multiple groups of mounting tubes 9 can also keep in contact with the surface, so multiple groups of movable blocks 11 can be squeezed into the corresponding mounting tubes 9 and further squeeze the squeezing button 10, so that multiple groups of warning lights 7 light up at the same time. When one or more groups of warning lights 7 are not lit, it means that one or more groups of movable blocks 11 are not completely squeezed into the corresponding mounting tubes 9, that is, the end of the top column 4 is not kept fully vertical and in contact with the concrete surface to be inspected. At this time, the staff can adjust the position of the device until multiple groups of warning lights 7 light up.
[0032] After completing the above operations, the servo motor 15 is controlled by the controller component 8 to drive the output shaft 16 and the gear 17 to rotate in the forward direction for a stroke. The gear 17 is meshed with the rack 3, so that the rebound tester body 1 can move a certain amplitude toward the mounting plate 5, and complete the pressurization task of the elastic part inside it with the top column 4. Then the hammering part of the rebound tester body 1 completes the hammering of the top column 4 and records the rebound distance. The servo motor 15 is controlled to drive the output shaft 16 and the gear 17 to rotate in the reverse direction for a stroke to restore the initial state, and the top column 4 is readjusted to other predetermined positions for detection.
[0033] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
