Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering quality detection, and in particular relates to a tester for intelligent construction engineering quality detection. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment; among them, building construction refers to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, residence, study, and public activities. After the completion of the building, the strength of the building surface needs to be tested using a concrete rebound tester. The main technical indicators include impact function; spring stiffness; hammer stroke; maximum static friction of the pointer system and average rigidity.

[0003] In the prior art, when the concrete rebound tester is in use, it is necessary to divide the area manually, and the area is usually 16, and a press-rebound test is required according to the area, so that the concrete rebound tester can display the data and take the average value for data comparison. However, manually pressing the rebound tester on the concrete surface is prone to cause skewness, so that the rebound tester cannot be pressed vertically, which is not only easy to cause data errors, but also easy to cause the hidden danger of reducing the service life of the rebound tester due to non-vertical wear. Moreover, manual pressing cannot make the position of the rebound tester's pressing point balanced, and it is always easy to press to the non-center of the divided area, which is not conducive to data collection, and makes the detection of concrete strength prone to the hidden danger of deviation.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides Figure 1-9 The tester for intelligent construction engineering quality inspection shown in the figure comprises a rebound detection mechanism 1, which is used for concrete quality inspection of construction engineering. The outer wall of the rebound detection mechanism 1 is connected to an operation positioning mechanism 3, and the bottom end of the operation positioning mechanism 3 is connected to a rebound positioning mechanism 2, wherein:

[0036] The rebound positioning mechanism 2 includes a support frame 201 and a control frame 202, one end of the inner wall of the support frame 201 is rotatably provided with a first positioning screw rod 207, one end of the outer wall of the first positioning screw rod 207 is threadedly connected to one side of the control frame 202, one end of the first positioning screw rod 207 passes through the support frame 201 and is fixedly provided with a first driven gear 208, one end of one side of the support frame 201 is fixedly provided with a first positioning frame 209, one side of the first positioning frame 209 is rotatably provided with a first driving gear 211, the outer wall of the first positioning frame 209 is fixedly provided with a first motor 210, the output end of the first motor 210 is fixedly connected to the middle position of the first driving gear 211, and the tooth surface of the first driven gear 208 is meshed with the tooth surface of the first driving gear 211;

[0037] A second positioning screw rod 212 is rotatably provided on one side of the inner wall of the control frame 202, one end of the second positioning screw rod 212 passes through the control frame 202 and is fixedly provided with a second driven gear 214, a second positioning frame 215 is fixedly provided on one end of one side of the control frame 202, a second driving gear 217 is rotatably provided on one side of the second positioning frame 215, a second motor 216 is fixedly provided on the other end of the second positioning frame 215, an output end of the second motor 216 is fixedly connected to the middle position of the second driving gear 217, and the tooth surface of the second driven gear 214 meshes with the tooth surface of the second driving gear 217; a display screen 203 is fixedly provided on one end of the control frame 202;

[0038] A first positioning groove 213 is formed at one end of the bottom of the control frame 202. The control frame 202 is slidably connected to the top of the support frame 201 through the first positioning groove 213. The other side of the bottom of the control frame 202 is in contact with the top of the support frame 201.

[0039] The output end of the second motor 216 fixed on one side of the second positioning frame 215 drives the second driving gear 217 to rotate, so that the second driving gear 217 drives the second driven gear 214 to mesh and rotate, so that the second driven gear 214 drives the second positioning screw 212 to rotate, so that the operating frame 301 threadedly connected to the outer wall of the second positioning screw 212 slides along the outer wall of the control frame 202 through the second positioning groove 304, and the output end of the first motor 210 fixed on one side of the first positioning frame 209 drives the first driving gear 211 rotates, and the tooth surface of the first driving gear 211 drives the tooth surface of the first driven gear 208 to mesh, so that the first driven gear 208 passes through the support frame 201 and drives the first positioning screw 207 to rotate, so that the control frame 202 threadedly connected to the outer wall of the first positioning screw 207 slides along the top of the support frame 201 through the positioning of the first positioning groove 213. Since the meshing mode of the first driving gear 211 and the first driven gear 208 and the meshing mode of the second driving gear 217 and the second driven gear 214 are the same as Figure 8 As shown, when the driving gear is rotating and the blank space without teeth contacts the driven gear, the driven gear stops rotating, so that the first positioning screw 207 or the second positioning screw 212 fixed on one side of the driven gear stops rotating, so that the control frame 202 and the operating frame 301 stop moving. In the gap of stopping movement, the rebound detection mechanism 1 just completes a springing operation. When the driving gear rotates a full circle, the driven gear just drives the control frame 202 or the operating frame 301 to move a certain distance through the positioning screw and perform a springing operation.

The first motor 210 drives the first driving gear 211 to rotate one turn after the second motor 216 drives the second driving gear 217 to rotate four turns. Similarly, the first driving gear 211 rotates in the reverse direction after every four turns, so that the displacement relationship of the impact is as follows: Fig. 9 As shown, through the meshing relationship between the driving gear and the driven gear, the rebound detection mechanism 1 is kept centered at each impact, so that the rebound pressure position of the rebound hammer is balanced and centered, which is beneficial to data collection and increases the accuracy of data collection.

The lifting frame 307 slides in a limited position through the fixed groove 308, and the outer wall of the rebound limit frame 101 contacts the control wheel 303 rotating on the inner wall of the limit groove 302, so that the rebound limit frame 101 is pressed vertically against the concrete surface, maintaining the vertical stability of the rebound detection mechanism 1, increasing the service life of the concrete rebound tester, and improving data accuracy.
