Description

Technical Field

[0001] This application relates to the field of concrete slab compaction testing technology, and in particular to a concrete slab compaction testing device. Background Technology

[0002] Currently, concrete slab compaction testing equipment is a specialized instrument used to assess the internal density and uniformity of concrete structures. By detecting defects such as void ratio, honeycomb, and pores in the concrete, it ensures that the strength and durability of the slab meet design requirements. When conducting compaction testing on concrete slabs after pouring, an ultrasonic testing instrument combined with a testing probe is usually used. The probe surface needs to be coated with a coupling agent and brought into contact with the slab surface. By emitting ultrasonic waves, internal defects are determined by the sound velocity / attenuation (the sound velocity is slow in low-density areas).

[0003] However, existing concrete slab compaction testing equipment has the following drawbacks: For example, under normal circumstances, when using an ultrasonic testing instrument and a testing probe to test the compaction of a slab, the testing probe is usually held manually and brought into contact with the slab surface. The position is then continuously moved and the testing position is recorded. Although this method can achieve the compaction test, it is not only necessary to hold the testing probe by hand, but also to mark the testing position with a pen. This operation is too cumbersome. Therefore, the method of manually holding the testing probe and recording results in low testing efficiency. Summary of the Invention

[0004] The purpose of this application is to replace manual hand-held operation by clamping the detection probe and automatically adjusting its position, thereby reducing the tediousness of manual hand-held operation and improving the efficiency of density detection.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a concrete slab pouring density testing device, comprising a vehicle body, a connecting frame fixedly connected to the upper surface of the vehicle body, a controller and an ultrasonic detector mounted on the upper surface of the connecting frame, a lifting assembly mounted on the upper surface of the vehicle body, a lifting seat mounted on the upper surface of the lifting assembly, a second motor fixedly connected to the outer wall of the lifting seat, a bidirectional lead screw fixedly connected to the output end of the second motor, the bidirectional lead screw rotatably connected inside the lifting seat, two lower clamps slidably connected inside the lifting seat, the two lower clamps threadedly connected to the outer wall of the bidirectional lead screw, an upper clamp rotatably connected inside the lower clamps, the other ends of the lower clamps and the upper clamps being fixedly connected by bolts and nuts, a testing probe placed between the lower clamps and the upper clamps, and the testing probe and the ultrasonic detector being electrically connected by a connecting wire.

[0006] Further preferably, the lifting assembly includes a fixed seat, which is fixedly connected to the upper surface of the vehicle body. A connecting rod is rotatably connected to the outer wall of the fixed seat. A slide is fixedly connected to the lower surface of the lifting seat. A slider is slidably connected inside the slide. The connecting rod is rotatably connected to the outer wall of the slider.

[0007] In a further preferred embodiment, a motor is fixedly connected to the outer wall of the slide block, and a threaded rod is fixedly connected to the output end of the motor. The threaded rod is rotatably connected inside the slide block, and the slider is threadedly connected to the outer wall of the threaded rod.

[0008] In a further preferred embodiment, a second fixed seat is fixedly connected to the lower surface of the lifting seat, a second connecting rod is rotatably connected to the outer wall of the second fixed seat, and a second sliding seat is fixedly connected to the upper surface of the vehicle body.

[0009] In a further preferred embodiment, a second slider is slidably connected inside the second slide block, the second connecting rod is rotatably connected to the outer wall of the second slider, and the second connecting rod is rotatably connected to the outer wall of the first connecting rod.

[0010] Further preferably, the outer wall of the vehicle body is fixedly connected to a handlebar, and four brake wheels are installed on the lower surface of the vehicle body.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] (1) Remove the bolts and nuts between the upper and lower clamps, then rotate to open the upper clamp, place the detection probe inside the lower clamp, rotate the upper clamp to combine with the lower clamp to clamp and fix the detection probe, and fix the lower clamp and the upper clamp with bolts and nuts. During use, apply coupling agent to the surface of the detection probe, start the motor to drive the two-way screw to rotate and cause the two lower clamps to slide to both sides, thereby driving the two detection probes to slide to both sides. After adjusting to the appropriate position, move the vehicle body to make the surface of the detection probe contact the surface of the floor slab, and then combine the ultrasonic detector and the detection probe to perform the compaction test of the floor slab. The personnel assist in recording the test position. By clamping and fixing the detection probe and automatically adjusting the position, the manual hand-held detection probe is replaced, which not only improves the convenience of compaction operation, but also improves the work efficiency of compaction test and solves the problem of cumbersome manual hand-held operation.

[0013] (2) Start the motor to drive the threaded rod to rotate, causing the slider to slide in the sliding block inside the slide seat, which in turn drives the connecting rod to rotate and adjusts the lifting seat. During the lifting adjustment, the fixed seat moves up and causes the connecting rod to rotate. After the connecting rod rotates, the slider slides in the sliding block inside the slide seat. The connecting rod provides auxiliary support, thereby achieving the lifting adjustment of the lifting seat, which in turn drives the detection probe to adjust. The height of the detection probe can be automatically adjusted according to the actual detection position. Attached Figure Description

[0024] Working principle: When it is necessary to test the density of a concrete slab after pouring, firstly, connect the ultrasonic testing instrument 103 to the two testing probes 305 with a sufficiently long wire. Then, remove the bolts and nuts between the lower clamp 303 and the upper clamp 304, rotate to open the upper clamp 304, place the testing probe 305 inside the lower clamp 303, and rotate the upper clamp 304 to clamp and fix the testing probe 305 with the lower clamp 303. Then, fix the lower clamp 303 and the upper clamp 304 with bolts and nuts, and start the motor 301 to drive the double... Rotating the lead screw 302 causes the two lower clamps 303 to slide, which in turn moves the two detection probes 305 to adjust. After the detection probes 305 are adjusted to the appropriate position, coupling agent is applied to the surface of the detection probes 305. Then, the vehicle body 1 is moved so that the surface of the detection probes 305 contacts the surface of the floor slab to be tested. The brake wheel 105 is locked to prevent the vehicle body 1 from moving. Then, the ultrasonic detector 103 and the detection probes 305 work together to test the density of the floor slab. This method not only solves the problem of cumbersome manual operation of the detection probes 305, but also enables automatic adjustment. The position of the detection probe 305 facilitates the detection of different locations on the floor slab surface. Simultaneously, the operator can record the detection location without simultaneously holding the probe 305 and recording the position, thus improving detection efficiency. When detecting locations at different heights on the floor slab, first move the vehicle body 1 to move the detection probe 305 away from the floor slab. Then, start the motor 205 to drive the threaded rod 206 to rotate, causing the threaded rod 206 to slide the slider 203. This, in turn, causes the connecting rod 202 to rotate, which in turn moves the lifting seat 3 and the fixed seat 207 upwards. The upward movement of the second 207 causes the second connecting rod 208 to move upward and rotate, causing the second connecting rod 208 to drive the second slider 209 to slide within the slide block 210. This allows the lifting and lowering adjustment of the detection probe 305 to be achieved through the lifting and lowering adjustment of the lifting seat 3. After the adjustment is completed, the lower clamp 303, upper clamp 304 and detection probe 305 are adjusted to move by the second motor 301 and the double-acting screw 302. Then, coupling agent is reapplied to the surface of the detection probe 305 and the vehicle body 1 is moved to make the surface of the detection probe 305 contact the surface of the floor slab, and then the detection work begins. This achieves convenient position adjustment.
