Description

Technical Field

[0001] This utility model relates to the field of hollow detection technology in building engineering, specifically a hollow detection hammer for building engineering. Background Technology

[0002] Building construction engineering encompasses the planning, design, construction, and completion of various technical tasks related to the construction, renovation, or expansion of buildings and ancillary structures and facilities, as well as the installation of associated lines, pipelines, and equipment. During the acceptance of building construction projects, quality inspection of the walls is required. During the inspection, hollow areas may be detected. Hollow areas are caused by air in the original masonry and plaster layers. In terms of building quality, hollow areas generally refer to the phenomenon of hollow areas between the floor, wall, and ceiling finishing layers and the structural layers due to poor adhesion or bonding, commonly known as "two layers of skin."

[0003] Existing hollow-sound detection hammers require manual testing by staff, which is time-consuming and labor-intensive. Furthermore, these hammers cannot adjust the striking force according to the thickness of the structural layer, making the wall surface easily damaged and difficult to repair when hollow areas are detected. Therefore, we offer a hollow-sound detection hammer for building engineering that solves these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hammer for detecting hollow areas in building engineering.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hollow detection hammer for building engineering, comprising a load-bearing frame, with wheels on both the left and right sides of the bottom of the load-bearing frame, three guide grooves arrayed at the center of the inside of the load-bearing frame, a movable rod slidably connected inside the guide groove, a striking hammer fixedly connected to the bottom end of the movable rod, a decibel meter located on the right side of the striking hammer on the bottom wall of the load-bearing frame, a guide rod fixedly connected inside the movable rod, a support spring fixedly connected inside the movable rod on the outer surface of the guide rod, a push rod fixedly connected to the top right side of the movable rod above the load-bearing frame, a pad fixedly connected to the top wall of the load-bearing frame near the top of the movable rod, limit plates fixedly connected to the top wall of the load-bearing frame on both the front and rear sides of the movable rod, an adjustment mechanism provided between the limit plates, and a power mechanism located on the top wall of the load-bearing frame on the right side of the movable rod.

[0008] Furthermore, a bracket connected to an external traction mechanism is provided on the right side of the load-bearing frame, and four traveling wheels are provided at the bottom of the load-bearing frame, extending to the bottom of the load-bearing frame.

[0009] Furthermore, the outer wall of the moving rod engages with the guide groove, and the top of the moving rod is connected to the push rod by a retaining ring.

[0011] Furthermore, a movable plate is fixedly connected between the left side walls of the limiting block, and support rods are slidably connected at both the front and rear ends inside the movable plate. The bottom of the support rods is fixedly connected to the top wall of the bearing frame, and an adjusting rod is rotatably connected to the center position inside the movable plate. The outer wall of the adjusting rod is threaded.

[0012] Furthermore, the power mechanism includes a connecting frame, with gears rotatably connected to the four corners of the bottom of the connecting frame. The gears mesh with each other through a transmission chain. A drive motor is fixedly connected to the top of the gear located on the left side of the rear end of the connecting frame.

[0013] Furthermore, a contact plate is provided on the left side of the transmission chain near the push rod.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this hollow-sound detection hammer for construction projects has the following advantages:

[0016] I. This utility model achieves adjustable striking force by rotating the adjusting rod, which drives the moving plate to move downward, and the moving plate drives the limiting block to move. Under the guidance of the limiting plate, the limiting block drives the extrusion tube to move, and the extrusion tube extrudes the support spring inside the moving rod, thereby achieving adjustable striking force. This solves the problem that existing wall hollow detection hammers cannot adjust the striking force according to the thickness of the structural layer, which leads to easy damage to the wall surface when hitting hollow areas. It has the advantage of easy adjustment of striking force.

[0017] II. When this utility model is in use, the external moving mechanism moves the device through the bracket on the right side of the supporting frame. The drive motor drives the gear to rotate, and the gear drives the contact plate to move around a "U" shaped trajectory through the transmission chain. Under the limit of the guide rail and the guide block, the contact plate intermittently drives the push rod to move upward. After the push rod is separated from the support of the contact plate, the moving rod drives the hammer to move downward under the action of the support spring. The hammer strikes the ground, and the decibel meter collects the sound of the strike. The test result is obtained based on the measured decibel. This solves the problem that the existing hollow detection hammer requires the staff to manually perform hollow tests, which is time-consuming and laborious. It has the advantage of automatic detection. Attached Figure Description

A pad 10 is fixedly connected to the top wall of the bearing frame 1 near the top of the movable rod 4. The pad 10 limits the downward movement distance of the movable rod 4.

[0026] Limiting plates 11 are fixedly connected to the top wall of the bearing frame 1 on both the front and rear sides of the moving rod 4. An adjustment mechanism is provided inside the limiting plates 11. The adjustment mechanism includes a limiting block 12. A slider is provided on the inner wall of the limiting plate 11 and is slidably connected to the side wall of the limiting block 12. A compression tube 13 is fixedly connected to the bottom of the limiting block 12 on the outer surface of the guide rod 7. The compression tube 13 exerts a compression effect on the support spring 8. A moving plate 14 is fixedly connected to the left side wall of the limiting block 12. Support rods 15 are slidably connected to the front and rear ends of the moving plate 14. The bottom of the support rods 15 is fixedly connected to the top wall of the bearing frame 1.

[0027] An adjusting rod 16 is rotatably connected to the center of the movable plate 14. The outer wall of the adjusting rod 16 is threaded. Rotating the adjusting rod 16 causes the movable plate 14 to move downwards. The movable plate 14 causes the limiting block 12 to move. Under the guidance of the limiting plate 11, the limiting block 12 causes the extrusion tube 13 to move. The extrusion tube 13 extrudes the support spring 8 inside the movable rod 4, thereby adjusting the striking force. A power mechanism is provided on the top wall of the bearing frame 1 to the right of the movable rod 4. The power mechanism includes a connecting frame 17. Gears 18 are rotatably connected to the four corners of the bottom of the connecting frame 17. The gears 18 mesh with each other through a transmission chain 19. A drive motor 20 is fixedly connected to the top of the gear 18 located on the left rear end of the connecting frame 17. The outer wall of the drive motor 20 is connected to the side wall of the bearing frame 1 through an extension frame.

[0028] A contact plate 21 is located on the left side of the transmission chain 19 near the push rod 9.

The drive motor 20 drives the gear 18 to rotate. The gear 18 drives the contact plate 21 to move around a "U" shaped trajectory through the transmission chain 19. Under the limiting of the guide rail 22 and the guide block 23, the contact plate 21 intermittently drives the push rod 9 to move upward. After the push rod 9 is released from the support of the contact plate 21, the moving rod 4 drives the hammer 5 to move downward under the action of the support spring 8. The hammer 5 strikes the ground. The decibel meter 6 collects the sound of the strike and obtains the test result based on the measured decibel.

[0029] Working principle: When using this hollow sound detection hammer for construction projects, rotating the adjusting rod 16 causes the moving plate 14 to move downwards. The moving plate 14 then moves the limiting block 12. Under the guidance of the limiting plate 11, the limiting block 12 moves the squeezing tube 13. The squeezing tube 13 squeezes the support spring 8 inside the moving rod 4, thereby adjusting the striking force. The external moving mechanism moves the device through the bracket on the right side of the load-bearing frame 1. The drive motor 20 drives the gear 18 to rotate. The gear 18 drives the contact plate 21 to move around a "U" shaped trajectory through the transmission chain 19. Under the limitation of the guide rail 22 and the guide block 23, the contact plate 21 intermittently drives the push rod 9 to move upwards. After the push rod 9 disengages from the support of the contact plate 21, the moving rod 4, under the action of the support spring 8, drives the striking hammer 5 to move downwards. The striking hammer 5 strikes the ground. The decibel meter 6 collects the striking sound, and the detection result is obtained based on the measured decibels.
