[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0026] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a hollow drum hammer for construction engineering management, comprising a hammer mechanism 1, an inner surface wall of the hammer mechanism 1 is movably inserted with an extension mechanism 2;
[0027] The extension mechanism 2 includes a fixed block 201, a limiting groove 202 is provided on one side of the outer wall of the fixed block 201, a connecting plate 203 is fixedly installed on one side of the outer wall of the fixed block 201, a slide groove 204 is provided at the bottom of the connecting plate 203, a slider 205 is slidably embedded in the inner surface wall of the slide groove 204, a threaded rod 206 is threadedly connected to the inner surface wall of the slider 205, a first turning handle 207 is fixedly connected to one side of the outer wall of the threaded rod 206, two bearings 208 are fixedly sleeved on the outer wall of the threaded rod 206, a mounting seat 209 is fixedly installed at the bottom of the slider 205, and the outer wall of the mounting seat 209 A movable groove 210 is opened on one side, and a movable rod 211 is movably inserted into the inner wall of the movable groove 210, and a mounting block 212 is fixedly sleeved on the outer wall of the movable rod 211, and a secondary hammer head 213 is fixedly installed on the bottom of the mounting block 212, and a worm gear 214 is fixedly sleeved on the outer wall of the movable rod 211, and a worm 215 is meshingly connected to the outer wall of the worm gear 214, and a second turning handle 216 is fixedly connected to one side of the outer wall of the worm 215, and two fixing plates 217 are movably sleeved on the outer wall of the worm 215, and one side of the outer wall of the mounting seat 209 is fixedly connected to one side of the outer wall of the two fixing plates 217.
[0028] The effect achieved by the entire embodiment 1 is that, after the fixing block 201 is successfully inserted into the slot 104, the staff observes the depth of the hidden structure of the building to be detected, and first rotates the first turning handle 207, and the first turning handle 207 drives the threaded rod 206 to rotate. Through the threaded transmission mechanism, the rotation of the threaded rod 206 causes the slider 205 to move left and right inside the slide slot 204, and the movement of the slider 205 drives the mounting seat 209 and the auxiliary hammer head 213 to move synchronously, thereby adjusting the auxiliary hammer head 213 to a hidden position that is difficult to directly reach. When the hidden structure to be detected is of an inclined design, the staff will participate in Consider the inclination angle of the structure and rotate the second handle 216. The second handle 216 will drive the worm 215 to rotate, and the rotation of the worm 215 will further drive the rotation of the worm wheel 214. Since the movable rod 211 is fixedly inserted in the worm wheel 214, the rotation of the worm wheel 214 will cause the movable rod 211 to deflect, thereby changing the angle of the auxiliary hammer head 213 to make it parallel to the surface of the inclined structure or adapt to its inclination angle. Such a design enables the hollow drum hammer to better adapt to complex and changeable building structures, ensuring that the staff can accurately detect the quality problems of hidden structures, thereby improving the accuracy and efficiency of detection.
[0029] Embodiment 2, as Figure 2-Figure 5As shown, the hammer mechanism 1 includes a handle rod 101, a telescopic rod 102 is fixedly installed on the top of the handle rod 101, a main hammer head 103 is fixedly installed on the top of the telescopic rod 102, a card slot 104 is provided on the outer wall of the telescopic rod 102, two mounting holes 105 are provided on the outer wall of the telescopic rod 102, springs 106 are fixedly installed on the inner walls of the two mounting holes 105, a pull plate 107 is fixedly connected between the outer walls of the two springs 106, a limit block 108 is fixedly installed on one side of the outer wall of the pull plate 107, the limit block 108 is movably inserted in the limit slot 202, and the fixed block 201 is movably inserted in the card slot 104.
[0030] The effect achieved by the entire embodiment 2 is that when it is necessary to inspect the hidden structure of the building, if the main hammer head 103 cannot reach the position that needs to be inspected, the staff will first pull the pull plate 107. The movement of the pull plate 107 will drive the limit block 108 to move to one side, thereby opening the slot 104 and making its interior unobstructed. At the same time, the movement of the pull plate 107 will cause the two springs 106 to deform, preparing for subsequent resetting. Then, the staff will insert the fixed block 201 into the slot 104. When the fixed block 201 is fully inserted, the limit block 108 will just match the limit slot 202. At this time, the staff can release the pull plate 107. Due to the elastic restoring force of the two springs 106, the limit block 108 will quickly fit into the limit slot 202, thereby completing the rapid installation of the fixed block 201 and ensuring that the fixed block 201 and the connecting plate 203 remain fixed. In this way, the staff can quickly disassemble and assemble the extension mechanism 2 according to the different positions that need to be inspected, thereby improving work efficiency and detection accuracy.
[0031] Working principle: When using a hollow hammer for testing, it is first necessary to evaluate the characteristics of the building structure to be tested. When the surface of the building structure is relatively flat, the main hammer head 103 can be used directly for testing. However, when there are hidden or difficult-to-reach parts of the building structure, it is necessary to first pull the pull plate 107. The movement of the pull plate 107 will drive the limit block 108 to move to one side. At the same time, the movement of the pull plate 107 will cause the two springs 106 to deform. Then, the fixing block 201 is accurately inserted into the slot 104. When the fixing block 201 is fully inserted, After insertion, the limit block 108 will automatically snap into the limit groove 202 on the fixed block 201 under the elastic restoring force of the two springs 106, so that the fixed block 201 can be installed quickly and firmly. Next, according to the depth of the hidden structure, the first turning handle 207 is rotated, and the rotation of the first turning handle 207 will drive the threaded rod 206 to rotate. Since the outer wall of the threaded rod 206 is threadedly connected with the inner wall of the slider 205, the rotational movement of the threaded rod 206 will be converted into a linear movement of the slider 205 in the slide groove 204, thereby realizing the slider 205 moves left and right, and the movement of the slider 205 will drive the mounting seat 209 and the auxiliary hammer 213 to move synchronously until the auxiliary hammer 213 can touch the position of the hidden structure. If the hidden structure has an inclination angle, it is necessary to adjust the angle of the auxiliary hammer 213 according to the actual inclination. At this time, the staff can turn the second handle 216, and the rotation of the second handle 216 will drive the worm 215 to rotate, thereby driving the worm wheel 214 to rotate. The rotation of the worm wheel 214 will deflect the movable rod 211, thereby realizing the angle adjustment of the auxiliary hammer 213, so that It remains parallel to the inclined structural surface or at an angle that adapts to the detection requirements, and the self-locking characteristics of the worm gear 214 and worm 215 keep the auxiliary hammer head 213 fixed. After the adjustment is completed, the staff can operate the handle rod 101 and extend or contract the length of the telescopic rod 102 to adjust the overall length of the hollow hammer so that it can reach the position to be detected more accurately. Subsequently, the auxiliary hammer head 213 is used to knock or vibrate the position to be detected, and the sound or vibration feedback generated by the knocking or vibration is analyzed to determine whether the building structure has quality problems such as hollowing.
