Description

Technical Field

[0001] The invention relates to the field of building detection, in particular to a building engineering quality detection instrument. Background Art

[0002] The quality inspection of construction projects is often carried out with a handheld drop weight deflection instrument. The drop weight hits the loader so that the test module reads the corresponding vertical, which is used to quickly assess the bearing capacity of the base layer on site.

[0003] When the equipment is in use, the user supports the top of the column, but the rebounding weight rises greatly, which can easily cause a certain amount of shaking to the column, thus affecting the data reading results. In addition, the user needs to support the column while catching the rebounding weight with his hand, further affecting the data accuracy. The weight is not easy to catch and can easily cause certain injuries to the operator. Summary of the invention

[0004] In view of the above problems, the present invention provides a construction engineering quality detector.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a construction project quality detector, whose structure includes: a test module, a loader, a rebound pad, a column, a drop hammer, and a self-fixing device. The loader is installed on the upper part of the test module, the rebound pad is provided with four and is arranged around the top of the loader, the column is vertically fixed on the top of the loader, the drop hammer is slidably engaged on the column, the self-fixing device is arranged at the top of the drop hammer, and the lower part of the column is provided with a limit groove. The self-fixing device is composed of a card plate, a sliding frame, a counterweight ring, and a compression pad. The card plate is engaged with the top of the drop hammer through a hinge, the sliding frame is arranged on the card plate along the length direction of the card plate, the compression pad is arranged at the bottom end of the sliding frame, and the counterweight ring is nested in the sliding frame and against the compression pad.

[0006] Preferably, four clamping plates are provided and are arranged around the top of the drop hammer. The top of the clamping plates is arc-shaped. The top of the clamping plates are combined into a circle with a diameter smaller than the diameter of the column. By arranging the clamping plates around, the self-fixing device as a whole can obtain stable force when the counterweight ring is working.

[0007] Preferably, the counterweight ring is nested on the sliding frame and connected to the card plate, the compression pad supports the counterweight ring to the top of the sliding frame, and the card plate is tilted upward due to the support of the compression pad on the counterweight ring. When the card plate is pressed down by the weight of the counterweight ring and turned into a horizontal state, it engages with the limit groove, and the counterweight ring is driven to fall together when the drop hammer falls. When the drop hammer touches the bottom and the final speed is reduced to zero, the counterweight ring continues to fall and compresses the compression pad, thereby driving the card plate to be pressed down and engage with the limit groove, so that the position of the drop hammer is fixed, preventing the drop hammer from rebounding significantly, and preventing further shaking of the column to cause data deviation, and at the same time, there is no need to perform manual operations.

[0008] Preferably, the distance from the top of the limit groove to the top of the rebound pad is equal to the sum of the drop weight height and the horizontal thickness of the clamping plate, thereby limiting the rebound range of the drop weight so that the self-fixing device can be stuck in the limit groove when the drop weight hits the bottom.

[0009] Preferably, the compression pad is composed of an outer layer and an inner spring pad, the inner spring pad is in the shape of a long rectangular strip, the outer layer is wrapped around the four sides of the inner spring pad, the inner spring pad is in the shape of a hollow sponge, and the outer layer wraps the inner spring pad in a sealed state. The hollow sponge-like inner spring pad enables the compression pad to shrink quickly when the counterweight ring sinks, allowing the counterweight ring to press down and drive the card plate to move further.

[0010] Preferably, air holes are provided on both sides of the outer covering layer, and the air holes are densely distributed on the outer covering layer on both sides of the inner spring pad. When the outer covering layer is under pressure, the air holes expand outward and absorb air into the inside, so that when the inner spring pad shrinks to restore its original shape, air is slowly absorbed through the air holes of the outer covering layer to fill the holes inside the inner spring pad, so that the counterweight ring rises slowly, and then the clamping plate can be slowly expanded when it shrinks sharply, ensuring that the clamping plate can be engaged with the limiting groove before the rebound pad drives the drop hammer to rebound and rise, further preventing the drop hammer from rebounding, and no manual operation is required.

[0011] Preferably, the compression pad is made of rubber material, and the outer layer and the inner spring pad are both independent structures, so that the compression and rebound energy of the inner spring pad are not affected by the elastic force of the outer layer.

[0012] Beneficial Effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention drives the counterweight ring to fall together with the falling hammer. When the final speed of the falling hammer is reduced to zero when it touches the bottom, the counterweight ring continues to fall and squeezes the squeezing pad, thereby driving the clamping plate to press down and engage with the limit groove, so that the position of the falling hammer touches the bottom and is fixed after it falls, preventing the falling hammer from rebounding significantly and preventing the falling hammer from further shaking the column and causing data deviation. At the same time, there is no need to perform manual operations to avoid accidents.

[0015] 2. The extrusion pad used in the present invention can shrink quickly when the counterweight ring sinks, allowing the counterweight ring to press down and drive the card plate to move further. When the inner spring pad shrinks to restore its original state, air is slowly sucked in through the pores of the outer layer to fill the holes inside the inner spring pad, so that the counterweight ring rises slowly, and then the card plate can be slowly expanded when it shrinks sharply, ensuring that the card plate can be engaged with the limit groove before the rebound pad drives the drop hammer to rebound and rise, further preventing the drop hammer from rebounding, and no manual operation is required.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the preferred implementation scheme of the present invention is further described below in conjunction with specific implementation schemes and accompanying drawings.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2As shown, the present invention provides a construction engineering quality detector, which structure includes: a test module 1, a loader 2, a rebound pad 3, a column 4, a drop hammer 5, and a self-fixing device 6. The loader 2 is installed on the upper part of the test module 1, the rebound pad 3 is provided with four and is arranged around the top of the loader 2, the column 4 is vertically fixed on the top of the loader 2, the drop hammer 5 is slidably engaged on the column 4, the self-fixing device 6 is arranged at the top of the drop hammer 5, and the lower section of the column 4 is provided with a limiting groove 41. The self-fixing device 6 is composed of a card plate 61, a sliding frame 62, a counterweight ring 63, and a compression pad 64. The card plate 61 is engaged with the top of the drop hammer 5 through a hinge, the sliding frame 62 is arranged on the card plate 61 along the length direction of the card plate 61, the compression pad 64 is arranged at the bottom end of the sliding frame 62, and the counterweight ring 63 is nested in the sliding frame 62 and abuts against the compression pad 64.

[0026] like Figure 3 As shown, there are four clamping plates 61 and they are arranged around the top of the drop hammer 5. The top of the clamping plates 61 is in an arc shape. The top of the clamping plates 61 is combined into a circle with a diameter smaller than the diameter of the column 4. By surrounding the clamping plates 61, the self-fixing device 6 as a whole can obtain stable force when the counterweight ring 63 is working.

[0027] like Figure 4 As shown, the counterweight ring 63 is nested on the sliding frame 62 and connected to the card plate 61, and the squeezing pad 64 supports the counterweight ring 63 to the top of the sliding frame 62. The card plate 61 is tilted upward under the support of the squeezing pad 64 on the counterweight ring 63. When the card plate 61 is pressed down by the weight of the counterweight ring 63 and turned into a horizontal state, it engages with the limiting groove 41, and drives the counterweight ring 63 to fall together when the drop hammer 5 falls. When the drop hammer 5 touches the bottom and the final speed is reduced to zero, the counterweight ring 63 continues to fall and squeezes the squeezing pad 64, thereby driving the card plate 61 to be pressed down and engage with the limiting groove 41, so that the position of the drop hammer 5 is fixed, preventing the drop hammer 5 from rebounding, and preventing further shaking of the column 4 to cause data deviation, and at the same time, there is no need to perform manual operations.

[0028] The distance from the top of the limiting groove 41 to the top of the rebound pad 3 is equal to the sum of the height of the drop hammer 5 and the horizontal thickness of the clamping plate 61, thereby limiting the rebound range of the drop hammer 5 so that the self-fixing device 6 can be stuck on the limiting groove 41 when the drop hammer 5 touches the bottom.

[0029] The working principle of the present invention is described as follows:

[0030] When the device is in use, the user holds the top of the column 4 with his hand and releases the drop hammer 5, so that the drop hammer 5 falls and hits the loader 2. The drop hammer 5 rebounds through the rebound pad 3. At the same time, the test module 1 reads the data transmitted by the loader 2, and analyzes the data to detect and evaluate the engineering quality;

[0031] When the drop hammer 5 falls, it drives the counterweight ring 63 to fall together. When the drop hammer 5 touches the bottom and the final speed is reduced to zero, the counterweight ring 63 continues to fall and squeezes the squeezing pad 64, thereby driving the clamping plate 61 to press down. When the drop hammer 5 touches the bottom, it is affected by the elastic force of the rebound pad 3, driving the drop hammer 5 to rebound upward, so that the clamping plate 61 is engaged with the limiting groove 41, so that the position of the drop hammer 5 is fixed and it will not rebound further upward, thereby preventing the rebound of the drop hammer 5 from further driving the column 4 to shake and causing data deviation. At the same time, there is no need to perform manual operations.

[0032] Embodiment 2

[0033] like Figure 5 As shown, the compression pad 64 is composed of an outer layer 641 and an inner spring pad 642. The inner spring pad 642 is in a rectangular shape. The outer layer 641 is wrapped around the four sides of the inner spring pad 642. The inner spring pad 642 is hollow sponge-like. The outer layer 641 wraps the inner spring pad 642 in a sealed state. The hollow sponge-like inner spring pad 642 enables the compression pad 64 to shrink quickly when the counterweight ring 63 sinks, allowing the counterweight ring 63 to press down and drive the clamping plate 61 to move further.

[0034] like Figure 6 As shown, air holes 6411 are provided on both sides of the outer layer 641, and the air holes 6411 are densely distributed on the surface of the outer layer 641 on both sides of the inner spring pad 642. When the outer layer 641 is under pressure, the air holes 6411 expand outward and absorb air into the inside, so that when the inner spring pad 642 shrinks to restore its original shape, air is slowly absorbed through the air holes 6411 of the outer layer 641 to fill the holes inside the inner spring pad 642, so that the counterweight ring 63 rises slowly, and then the clamping plate 61 can be slowly expanded when it shrinks sharply, ensuring that the clamping plate 61 can be engaged with the limiting groove 41 before the rebound pad 3 drives the drop weight 5 to rebound and rise, so as to further prevent the drop weight 5 from rebounding, and no manual operation is required.

[0035] The compression pad 64 is made of rubber material, and the outer layer 641 and the inner spring pad 642 are both independent structures, so that the compression and rebound energy of the inner spring pad 642 are not affected by the elastic force of the outer layer 641.

[0036] The working principle of the present invention is described as follows:

[0037] When the counterweight ring 63 sinks, the extrusion pad 64 can shrink quickly, allowing the counterweight ring 63 to press down and drive the card plate 61 to move further. When the inner spring pad 642 shrinks to restore its original state, air is slowly sucked in through the air holes 6411 of the outer layer 641 to fill the holes inside the inner spring pad 642, so that the counterweight ring 63 rises slowly, and then the card plate 61 can slowly expand when it shrinks sharply, ensuring that the card plate 61 can be engaged with the limit groove 41 before the rebound pad 3 drives the drop hammer 5 to rebound and rise, further preventing the drop hammer 5 from rebounding, and preventing the drop hammer 5 from rebounding and further driving the column 4 to shake and cause data deviation, without the need for manual operation.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and range of equivalent elements of the claims are included in the present invention. Any reference sign in the claims should not be regarded as limiting the claims involved.
