A building detection house wall hardness detection equipment

Abstract

This utility model relates to the field of building inspection technology, specifically to a building wall hardness testing device, including a counterweight base. An L-shaped bracket is fixedly installed on one side of the top of the counterweight base, and an adjustment displacement mechanism is provided at the top of the counterweight base. This building wall hardness testing device, through the adjustment displacement mechanism, uses a first motor to drive a first transmission screw to rotate, causing a first moving screw block to move laterally on the first transmission screw. Simultaneously, a support slider slides on a support rod to assist, driving the reinforcement mounting frame and the overall testing device to adjust their vertical position. A second motor drives a second transmission screw to rotate, causing a second moving screw block to move laterally within a limiting groove. This precisely controls the lateral position of the mounting connecting block, the L-shaped support plate, and the rebound hammer body. Compared to existing technologies that can only adjust the vertical height, this device can conveniently change the lateral position of the testing device, significantly expanding the testing range.

This utility model includes a base, a storage box fixedly installed at the top center of the base, a support block fixedly installed on one side of the top of the base, a support plate hinged to the top of the support block, and first electric push rods hinged to both sides of the support plate. The outer ends of the first electric push rods are hinged to the top of the base. A sliding groove is opened on the outer wall of the support plate. A lead screw motor is fixedly installed at the top of the inner cavity of the sliding groove. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the bottom of the inner cavity of the sliding groove.

The existing technology can only adjust the vertical height of the device, which limits the detection range. When the horizontal position needs to be detected, the entire device needs to be moved, which affects the convenience of use. Utility Model Content

A mounting plate 308 is fixedly installed on the side of the reinforcing mounting bracket 307 away from the first moving screw block 304 and the supporting slider 306. A limiting groove 309 is provided on the side of the mounting plate 308 away from the reinforcing mounting bracket 307. A positioning through groove 310 is provided at the top of the reinforcing mounting bracket 307. A second motor 311 is fixedly installed on one side of the mounting plate 308. The output shaft of the second motor 311... The second transmission screw 312 is fixedly connected to the second transmission screw 312 via a coupling. The second transmission screw 312 extends into the interior of the limiting slide groove 309. A second bearing seat 313 is fixedly installed on the inner wall of the limiting slide groove 309 on the side away from the second motor 311. The side of the second transmission screw 312 away from the second motor 311 is fixedly connected to the interior of the second bearing seat 313. A second moving screw block 314 is threadedly connected to the outer end of the second transmission screw 312. A positioning slider 315 is fixedly installed on the top of the second moving screw block 314. The positioning slider 315 extends through the positioning through groove 310 to the mounting cross plate. At the top of 308, the first motor 301 is started. The output shaft of the first motor 301 drives the first transmission screw 302 to rotate. The first moving screw block 304 moves up and down on the first transmission screw 302, thereby driving the reinforcing mounting bracket 307 and the mounting horizontal plate 308 to move. The second motor 311 is started. The second motor 311 drives the second transmission screw 312 to rotate through the coupling. The second moving screw block 314 moves on the second transmission screw 312 and moves laterally within the limiting slide groove 309, precisely controlling the lateral position of the mounting connecting block 4, the L-shaped support plate 5 and the rebound spring body 8.

[0027] A mounting connection block 4 is fixedly installed on the side of the second movable screw block 314 away from the reinforcing mounting bracket 307. An L-shaped support plate 5 is fixedly installed on the side of the mounting connection block 4 away from the second movable screw block 314. An electric push rod 6 is fixedly installed on the side of the L-shaped support plate 5 away from the mounting connection block 4. A connecting mounting block 7 is fixedly installed on the output end of the electric push rod 6. A rebounder body 8 is fixedly installed on the side of the connecting mounting block 7 away from the electric push rod 6.

The limit block 10 is movably connected inside the limit groove 9. Universal wheels 11 are installed at the four corners of the bottom end of the counterweight base 1. The distance between the rebounder body 8 and the wall is adjusted by the electric push rod 6. The output end of the electric push rod 6 extends or shortens, driving the connecting mounting block 7 and the rebounder body 8 to move.

[0028] Working Principle: When it is necessary to test the hardness of a building wall, first move the device to the desired position, then connect it to an external power source, and electrically connect the device to the controller. When it is necessary to adjust the vertical height of the testing device, start the first motor 301. The output shaft of the first motor 301 drives the first transmission screw 302 to rotate, and the first moving screw 304 moves up and down on the first transmission screw 302. At the same time, the support slider 306 slides on the support slide rod 305 through the crossbar fixedly connected to the middle of the first moving screw 304, assisting the first moving screw 304 to move smoothly, thereby driving the entire testing device on the reinforced mounting frame 307 and the mounting plate 308 to move up and down, quickly adjusting to the approximate height position required for testing. If it is necessary to adjust the rebound hammer body 8 laterally, start the second motor 311. The second motor 311 drives the second transmission screw 312 to rotate through the coupling, and the second moving screw 314 moves up and down on the second transmission screw 312. The device moves upward and laterally within the limiting groove 309. The positioning slider 315 passes through the positioning through groove 310, precisely controlling the lateral position of the mounting connecting block 4, the L-shaped support plate 5, and the rebound hammer body 8, ensuring that the rebound hammer body 8 is accurately aligned with the detection point on the wall. Once the rebound hammer body 8 reaches the appropriate lateral position, the distance between the rebound hammer body 8 and the wall is adjusted by the electric push rod 6. The output end of the electric push rod 6 extends or shortens, driving the connecting mounting block 7 and the rebound hammer body 8 to move. The limiting block 10 slides within the limiting groove 9, ensuring that the rebound hammer body 8 does not deviate during the movement, until the rebound hammer body 8 maintains a suitable detection distance from the wall surface. At this point, the operator uses the rebound hammer body 8 to perform hardness testing on the wall. The rebound hammer body 8 uses the HT-225W model integrated digital display rebound hammer. The rebound hammer body 8 operates according to the standard testing procedure to obtain wall hardness data. After the test is completed, if it is necessary to test other locations, the above adjustment steps can be repeated to flexibly adjust the position of the rebound hammer body 8.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
