Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and particularly to a positioning device for a mortar rebound hammer. Background Art

[0002] A mortar rebound hammer is a device used for non-destructively detecting the compressive strength of masonry mortar in industrial and civil buildings. It drives a striker through a spring, and the instantaneous elastic deformation recovery force generated by striking the mortar surface causes the hammer to drive the pointer to bounce back, indicating the rebound distance, thereby obtaining a rebound value, which is used as one of the evaluation indicators for the compressive strength of mortar. It is applicable to the non-destructive detection of the compressive strength of masonry mortar in sintered common brick masonry of general industrial and civil buildings, and is used to test the compressive strength of concrete. It is the most widely used non-destructive testing instrument for concrete compressive strength in on-site testing, and is the fastest, simplest, and most economical testing method for obtaining the quality and strength of concrete.

[0003] The applicant retrieved and obtained the following prior art. Specifically, the patent with the publication number CN219084573U discloses a mortar rebound hammer with a positioning function, which relates to the technical field of mortar rebound hammers. It includes a positioning device for positioning, a fixing device for installing the rebound hammer is arranged on the surface of the positioning device, a mortar rebound hammer body for measuring the compressive strength of mortar is arranged inside the fixing device, and a cleaning device for cleaning the dust at the measurement point is arranged inside the positioning device. For this mortar rebound hammer with a positioning function, the base is placed parallel to the concrete test surface, and the connecting rod is pressed through the handle to press the first spring, pushing the mortar rebound hammer body through the positioning hole to measure the concrete test surface. Through the cooperation of the chute and the slider, it is ensured that the mortar rebound hammer body is perpendicular to the concrete test surface, thereby improving the measurement efficiency and the accuracy of the measurement results, and achieving the effect of improving the practicability of the equipment.

[0004] It can be seen from the above patent that although this mortar rebound hammer with a positioning function can ensure that the mortar rebound hammer body is perpendicular to the concrete test surface through the cooperation of the chute and the slider, thereby improving the measurement efficiency and the accuracy of the measurement results, in the actual use process, multiple points usually need to be selected within the test area. However, this mortar rebound hammer can only perform vertical impacts within the range of the positioning hole and cannot conveniently adjust the position to cover other test points, making it necessary for the staff to lift and move the entire equipment again each time they change the test point. This not only makes the operation cumbersome, time-consuming, and laborious, but also easily affects the positioning accuracy due to the secondary adjustment of the base position, making it inconvenient to use. Summary of the Invention

[0026] Embodiment 1:

[0027] The present invention provides a positioning device for a mortar rebound hammer.

[0028] In an embodiment of the present invention, the positioning device for a mortar rebound hammer includes a fixed frame 1 and a plurality of positioning components. A connecting plate detachably connected to an external structure is provided on the fixed frame 1. Each of the plurality of positioning components includes a positioning block 2 and a movable rod 3. The movable rod 3 is installed on the fixed frame 1 with limited movement. The positioning block 2 passes through a plurality of movable rods 3 and can move along the extension direction of the movable rods 3. A positioning hole 4 for the impact rod of the mortar rebound hammer to pass through is formed on the positioning block 2.

[0029] Specifically, as Figure 1 and Figure 2As shown, in the positioning device of the mortar rebound hammer of the present invention, since the connecting plate is provided on the fixed frame 1, the staff can install the fixed frame 1 to a preset position through the connecting plate to meet the use requirements of the mortar rebound hammer. Further, since the movable rods 3 of several positioning components are installed on the fixed frame 1 in a limited movement manner, the installation method of the movable rods 3 and the fixed frame 1 in a limited movement manner can be adopted as sliding clamping, etc. For example, a chute is opened on the fixed frame 1, and the movable rod 3 extends into the chute and thus realizes the sliding clamping with the fixed frame 1, so that the movable rod 3 can slide relative to the fixed frame 1 in the front-rear direction; at the same time, the positioning block 2 in the positioning component is inserted through the movable rod 3, so that the positioning block 2 can slide relative to the fixed frame 1 on the movable rod 3 in the left-right direction, and the structural design is simple and reasonable.

[0030] It can be understood that when the mortar rebound hammer needs to be used, the staff passes the impact rod of the mortar rebound hammer through the positioning hole 4 so that the positioning hole 4 is inserted and matched with the impact rod of the mortar rebound hammer. At this time, the inclination state of the impact rod of the mortar rebound hammer can be restricted through the positioning hole 4, so that it is always perpendicular to the test surface, thereby effectively avoiding the problem of inclined impact caused by manual operation, eliminating the measurement error (such as the rebound value being too high or too low) generated therefrom, making the test result more in line with the standard specification requirements, and improving the accuracy of the test result. In addition, when other test points need to be impacted, the staff can directly slide the positioning block 2 to the test point position, and then insert the impact rod of the mortar rebound hammer into the positioning hole 4, so that the rapid positioning of the impact rod of the mortar rebound hammer can be realized. By installing the fixed frame 1 once, the vertical impact test requirements of the mortar rebound hammer for multiple test points can be met. The staff can quickly complete the positioning without additionally fixing the placement position of the fixed frame 1, which not only reduces the operation difficulty, improves the use convenience, but also ensures the detection efficiency, and is especially suitable for engineering scenarios that require multi-point continuous measurement.

[0031] In an embodiment, two movable rods 3 that are parallel to each other and spaced apart are inserted through the positioning block 2, and the positioning hole 4 is located between the two movable rods 3. Specifically, as Figure 1 and Figure 2 shown, the two parallel and spaced-apart movable rods 3 can keep the positioning block 2 in a stable horizontal state during the sliding process, preventing problems such as deflection of the positioning block 2 that are likely to occur due to a single movable rod 3. Further, since the positioning hole 4 opened on the positioning block 2 is located between the two movable rods 3, the impact rod of the mortar rebound hammer can pass through the positioning hole 4 and then abut against the test surface. The two movable rods 3 being spaced apart provides an avoidance space for the impact rod of the mortar rebound hammer, and the structural design is simple and reasonable.

[0032] In an embodiment, limiting grooves 5 are respectively opened on the opposite sides of the fixed frame 1, and the two ends of the two movable rods 3 are respectively inserted through the two limiting grooves 5 and are in sliding contact and cooperation with the limiting grooves 5. Specifically, asFigure 1 and Figure 2 As shown, the sliding contact and cooperation between the two movable rods 3 and the two limiting grooves 5 not only enable the positioning block 2 to slide in the front-back direction, meeting the rapid positioning requirements of the positioning block 2 for different test points, but also prevent the two movable rods 3 from detaching from the fixed frame 1 during the sliding adjustment process. The structural design is simple and reasonable. In addition, it should be noted that during the actual use of the present invention, both ends of the two movable rods 3 are respectively provided in a cylindrical shape or are installed with rolling elements, thereby improving the smoothness of the sliding adjustment of the movable rods 3.

[0033] In another embodiment, mounting blocks 6 that are in sliding contact and cooperation with the limiting grooves 5 are respectively provided at both ends of the two movable rods 3. A plurality of notch grooves are respectively and evenly spaced along the extending directions of the groove walls of the two limiting grooves 5, and protrusions for plugging and cooperating with any one of the notch grooves are formed on the mounting blocks 6. It can be understood that, as Figure 1 shown, the sliding contact and cooperation between the mounting blocks 6 and the limiting grooves 5 can prevent the movable rods 3 from detaching from the fixed frame 1 during the sliding adjustment process. The structural design is simple and reasonable. Further, since a plurality of notch grooves are respectively provided on the two limiting grooves 5, and protrusions are formed on the mounting blocks 6, when the mounting blocks 6 slide and adjust in the limiting grooves 5, the protrusions on the mounting frame will be plugged into the notch grooves on the limiting grooves 5 at this time, thereby realizing the rapid adjustment and positioning of the movable rods 3. That is, during the actual production and manufacturing process of the present invention, the staff can open corresponding notch grooves on the limiting grooves 5 according to the distances between a plurality of test points. When the protrusions on the mounting blocks 6 slide to be plugged and cooperate with the notch grooves, the movable rods 3 are exactly at the adjusted positions of the preset test points at this time, and further the rapid adjustment and positioning of the positioning blocks 2 on the movable rods 3 can be realized, improving the test efficiency and being more convenient and reliable to use.

[0034] In one embodiment, as Figure 2 shown, a boss 7 is formed on the top surface of the positioning block 2, a positioning hole 4 is opened on the boss 7, and a mounting hole is opened on the hole wall of the positioning hole 4. A clamping block 8 for abutting against the impact rod of the mortar rebound instrument is installed in the mounting hole in a limited and movable manner. It can be understood that the limited and movable installation method of the clamping block 8 in the mounting hole can adopt spring connection, that is, a spring is provided in the mounting hole. The spring has the characteristics of compact structure and large elastic restoring force. When the staff inserts the impact rod of the mortar rebound instrument into the positioning hole 4, the clamping block 8 firmly abuts against the impact rod of the mortar rebound instrument under the action of the elastic member at this time, thereby improving the installation stability of the impact rod of the mortar rebound instrument and keeping it in a position state perpendicular to the test surface all the time, ensuring the accuracy of the test results. The structural design is ingenious and reasonable.

[0035] In one embodiment, the number of the mounting holes is multiple, and clamping blocks 8 are arranged in all the multiple mounting holes. It can be understood that, as Figure 2As shown, the impact rod of the mortar rebound hammer can be multi-point abutted and limited by a plurality of clamping blocks 8, thereby further improving the installation stability of the impact rod of the mortar rebound hammer.

[0036] In one embodiment, scales 9 are respectively arranged on the fixing frame 1 along its extending direction and width direction. Specifically, as Figure 1 shown, by arranging scales 9 on the fixing frame 1 along its front-back and left-right directions respectively, it enables the staff to quickly, conveniently and accurately move and adjust the positioning block 2, ensuring the consistency and uniformity of the distances between several test points, guaranteeing the accuracy of the test results, and being convenient and reliable to use.

[0037] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
