[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the rotating shaft rotates forward, the rotating shaft drives the circular inner ring and two driving rollers to rotate synchronously. There is a height difference between the two driving rollers. The rotation of the two driving rollers causes the circular outer ring and the telescopic shaft to swing at the same time. The swing angle generated by the telescopic shaft acts on the striking block, causing the striking block to move up and down, so that the striking block strikes the drill bit, thereby enhancing the impact force of the drill bit, avoiding the jamming of the drill bit, and ensuring smooth drilling.

[0016] 2. In the present invention, when the striking block strikes the drill bit with an upward and downward amplitude, the pressure rod and the piston are driven to move downward synchronously through the cross bar, so that the piston slides in the compression cylinder, and pressurization is generated in the compression cylinder. The internal gas of the compression cylinder enters the bellows. At this time, pressurization is generated in the bellows, and the internal gas of the bellows is ejected from the nozzle to spray the powder and slag in the drill hole, thereby discharging the powder and slag in the drill hole, further ensuring smooth drilling.

[0017] 3. The present invention can inject water into the water tank according to demand. When the pressure rod moves upward, the pressure rod drives the piston to move upward, so that negative pressure is generated inside the compression cylinder, and the water in the water tank enters the compression cylinder through the hose. In addition, the one-way solenoid valve can prevent gas or liquid from flowing back. When the pressure rod moves downward, the water in the compression cylinder is sprayed out from the nozzle. Through the uninterrupted up and down movement of the pressure rod, the water in the water tank is continuously sprayed out through the nozzle, which not only rinses the powder residue in the hole, but also prevents the powder residue and dust from splashing.

[0018] 4. The present invention only needs to close the one-way solenoid valve. When the pressure rod moves downward, the pressure rod drives the piston to move downward, and the piston further increases the internal pressure of the compression cylinder. At this time, the internal hydraulic pressure or air pressure of the compression cylinder enters the bellows, causing the bellows to generate an expansion force, so that the circular plate and the compression cylinder have an upward push force, and the compression cylinder drives the ring frame and the limit ring to have an upward trend, and then the limit ring drives the drill bit to have an upward force. The upward force of the drill bit is used to perform a pull-out test on the building, and then the internal strength of the building is judged.

[0019] 5. The present invention is configured by coordinating two water tanks and pipes. Water can be injected into the water tanks as needed by opening the screw caps. The two water tanks are interconnected through pipes. Only the support plate needs to be in contact with the top of the building. By observing the scale lines on the transparent glass, it can be determined whether the liquid levels of the two water tanks are at the same scale value, thereby determining the horizontality of the building.

[0020] 6. In the present invention, when the servo motor is started in reverse, the output end of the servo motor causes the main bevel gear to rotate, and the main bevel gear drives the rotating shaft to rotate. Through the matching arrangement of the rotating shaft, the slave bevel gear, the rotation of the main gear and the slave gear, the rotating shaft drives the slave gear to rotate, and then the slave gear drives the drill bit to reverse. When the drill bit reverses, it is difficult for the drill bit to drill into the interior of the building. Similarly, when the servo motor is started in reverse, the knocking block knocks the drill bit, and then the drill bit has a knocking force on the surface of the building, so as to judge whether the surface hardness of the building meets the standard, whether it is peeling or fragile, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] The present invention provides the following technical solutions (see Figure 1-15 ): See also Figure 1 , Fig.14 and Fig.15 A quality inspection device for construction engineering management includes a support plate 1, a motor frame 2 and a double cylinder 3. The bottom of the motor frame 2 is provided with a rotating shaft 4 through a bearing. The surface of the rotating shaft 4 is provided with a knocking assembly 5. The knocking assembly 5 includes a circular inner ring 501. The surface of the circular inner ring 501 is provided with two driving rollers 502, and the height positions of the two driving rollers 502 are inconsistent and far away from each other. The surface of the circular inner ring 501 is sleeved with a circular outer ring 503, and the circular outer ring 503 is adapted to the circular inner ring 501. The inner of the circular outer ring 503 is provided with a circular outer ring 503. A guide groove 504 is provided on the side wall, and the driving roller 502 slides inside the guide groove 504. A telescopic shaft 505 is fixedly connected to the outer side of the circular outer ring 503, and a knocking block 506 is movably connected to the end of the telescopic shaft 505. The two driving rollers 502 rotate around the axis of the rotating shaft 4, and the two driving rollers 502 drive the circular outer ring 503 to generate a swing amplitude through the guide groove 504. The swing amplitude of the circular outer ring 503 causes the knocking block 506 to generate an up and down amplitude through the telescopic shaft 505, and both sides of the knocking block 506 are fixedly connected with cross bars 6.

[0025] More specifically, when inspecting a building, it is necessary to drill a hole in the building and take out internal samples of the building for inspection. Usually, when the drill bit 19 drills a hole in the building, the drill bit 19 does not have impact force and is prone to jamming, which is time-consuming and laborious. When the rotating shaft 4 rotates forward, the rotating shaft 4 drives the circular inner ring 501 to rotate, so that the circular inner ring 501 drives the two driving rollers 502 to rotate. There is a height difference between the two driving rollers 502. The rotation of the two driving rollers 502 causes the circular outer ring 503 and the telescopic shaft 505 to generate a swing angle at the same time. At this time, the circular outer ring 503 does not rotate on its own. The swing angle generated by the telescopic shaft 505 acts on the knocking block 506 through the telescopic shaft 505, causing the knocking block 506 to move up and down, so that the knocking block 506 knocks the drill bit 19. When the drill bit 19 rotates forward to drill, the impact force of the drill bit 19 is enhanced, the jamming of the drill bit 19 is avoided, and the smooth drilling of the drill bit 19 is ensured.

[0026] See also Figure 1 , Figure 4 , Figure 6and Fig. 9 The double cylinder 3 is internally slidably connected with a compression assembly 7, and the compression assembly 7 includes a compression rod 701 and a compression cylinder 702. The bottom end of the compression rod 701 is fixedly connected with a piston 703, and the piston 703 is arranged inside the compression cylinder 702. The bottom of the compression cylinder 702 is fixedly connected with a circular plate 704, and a gap is left between the circular plate 704 and the compression cylinder 702. The lower surface of the circular plate 704 is fixedly connected with a bellows 705, and the compression cylinder 702 is connected to the bellows 705. One side of the bottom of the bellows 705 is connected with a nozzle 706, and a one-way solenoid valve 707 is arranged on the nozzle 706.

[0027] When drilling inspection of a building, the drill bit 19 usually produces broken powder slag in the borehole during drilling. The powder slag is not easy to discharge, which affects the drilling, and the powder slag collection can be used as a sample for detection; when the knocking block 506 knocks the drill bit 19 with an up and down amplitude, the knocking block 506 drives the pressure rod 701 to move downward through the cross bar 6, and the pressure rod 701 drives the piston 703 to move downward, so that the piston 703 slides in the compression cylinder 702, and the compression cylinder 702 is pressurized. The internal gas of the compression cylinder 702 enters the bellows 705. At this time, the bellows 705 is pressurized, and the internal gas of the bellows 705 is ejected from the nozzle 706, which sprays the powder slag in the borehole, and then discharges the powder slag in the borehole, further ensuring the smooth drilling of the drill bit 19.

[0028] When drilling inspection on a building, the drill bit 19 usually produces powder, slag and dust during drilling, which affects the operation and is not cleaned up properly. You only need to open the screw cap 11 and inject water into the water tank 8 as needed. When the pressure rod 701 moves upward, the pressure rod 701 drives the piston 703 to move upward, so that negative pressure is generated inside the compression cylinder 702, and the water in the water tank 8 enters the compression cylinder 702 through the hose 12. In addition, the one-way solenoid valve 707 can prevent gas or liquid from flowing back. When the pressure rod 701 moves downward, the water in the compression cylinder 702 is sprayed out from the nozzle 706. Through the uninterrupted up and down movement of the pressure rod 701, the water in the water tank 8 is continuously sprayed out through the nozzle 706, which not only rinses the powder in the hole, but also prevents the powder and slag from splashing.

[0029] When drilling inspection is performed on a building, it is necessary to drill the drill bit 19 into the interior of the building, perform a pull-out test on the building, and determine whether the internal strength of the building meets the standard; at this time, the one-way solenoid valve 707 is closed, and the drill bit 19 is located inside the building. The one-way solenoid valve 707 prevents liquid or gas from passing through the hose 12. When the pressure rod 701 moves downward, the pressure rod 701 drives the piston 703 to move downward, and the piston 703 further increases the internal pressure of the compression cylinder 702. At this time, the internal hydraulic pressure or air pressure of the compression cylinder 702 enters the bellows 705, causing the bellows 705 to generate an expansion force, which makes the circular plate 704 and the compression cylinder 702 have an upward push force, and the ring frame 18 and the motor frame 2 driven by the compression cylinder 702 are lifted upward, and the ring frame 18 drives the limit ring 16 to lift upward, and the limit ring 16 drives the drill bit 19 to have an upward force, and makes the support plate 1 contact with the building, and the building is pulled out through the upward force of the drill bit 19, so as to determine the internal strength of the building.

[0030] See also Figure 1 , Figure 5 and Figure 8 Two water tanks 8 are arranged on the left and right sides of the upper surface of the support plate 1. The bottoms of the inner sides of the two water tanks 8 are connected by two pipes 9. The two pipes 9 are respectively located at the corners of the water tanks 8. Transparent glass 10 is arranged on the front and back sides of the water tank 8. The surface of the transparent glass 10 is provided with scale lines. The top of the water tank 8 is threadedly connected with a screw cover 11.

[0031] More specifically, when inspecting a building project, check whether the levelness of the building meets the standard; through the coordinated arrangement of the two water tanks 8 and the pipe 9, it is only necessary to open the screw cap 11 to inject water into the water tank 8 as needed, and the two water tanks 8 are interconnected through the pipe 9. It is only necessary to contact the support plate 1 with the top of the building, and by observing the scale lines on the transparent glass 10, it is determined whether the liquid levels of the two water tanks 8 are at the same scale value, thereby determining the levelness of the building.

[0032] See also Figure 5 and Figure 7 The screw cap 11 includes a cover body 1101, a through hole 1102 is opened on the top of the cover body 1101, a free telescopic rod 1103 is arranged inside the through hole 1102, a float 1104 is arranged at the free end of the free telescopic rod 1103, and the float 1104 prevents water from overflowing, a hose 12 is arranged on the inner side of the bottom of the water tank 8, the end of the hose 12 is connected to the bottom of the compression cylinder 702, and a one-way valve 13 is arranged at the connection between the hose 12 and the water tank 8.

[0033] More specifically, when negative pressure is generated inside the compression cylinder 702, the liquid or gas in the water tank 8 enters the compression cylinder 702 through the hose 12. At this time, negative pressure is generated in the water tank 8, and external gas enters the water tank 8 through the through hole 1102. The float 1104 remains stationary. If the liquid in the water tank 8 shakes, the float 1104 is lifted up by the buoyancy of the shaking liquid to prevent the liquid from overflowing. When the two water tanks 8 are tested for levelness, the water in the two water tanks 8 is circulated to each other through the pipe 9, then the gas volume of the water tank 8 changes, and the gas is discharged or enters from the through hole 1102, thereby ensuring that the liquid levels in the two water tanks 8 always remain at the same level. The one-way valve 13 is set to prevent gas or liquid from flowing back into the water tank 8.

[0034] See also Figure 5 and Figure 7 A servo motor 14 is fixedly installed on the top of the motor frame 2, and a main bevel gear 15 is fixedly connected to the output end of the servo motor 14. A slave bevel gear 17 is fixedly connected to the top of the rotating shaft 4, and the slave bevel gear 17 is meshed with the main bevel gear 15.

[0035] More specifically, when inspecting a building, it is necessary to perform a knocking treatment on the surface of the building to determine whether the surface hardness of the building meets the standard, whether it is peeling or fragile, etc.; at this time, the handle 32 is held for operation, and only the support plate 1 needs to be in contact with the building, and appropriate pressure is applied by the hand. When the servo motor 14 is reversed and started, the output end of the servo motor 14 causes the main bevel gear 15 to rotate, and the main bevel gear 15 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the slave bevel gear 17 to rotate, and the slave bevel gear 17 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the main gear 23 to rotate, and the main gear 23 drives the slave gear 21 to rotate, and the slave gear 21 drives the drill bit 19 to reverse. When the drill bit 19 reverses, it is difficult for the drill bit 19 to drill into the interior of the building. Similarly, when the servo motor 14 is reversed and started, the knocking block 506 knocks the drill bit 19, and then the drill bit 19 has a knocking force on the surface of the building to determine whether the surface hardness of the building meets the standard, whether it is peeling or fragile, etc.

[0036] See also Figure 1 , Figure 6 , Fig.11 , Fig.12 and Fig.14, the number of double-piece cylinder 3 and compression cylinder 702 is two respectively, and the double-piece cylinder 3 is adapted to the compression cylinder 702, and a ring frame 18 is fixedly connected between the two compression cylinders 702, and a drill bit 19 is penetrated inside the ring frame 18, and the drill bit 19 is located below the knocking block 506, and the up and down amplitude of the knocking block 506 acts on the top of the drill bit 19, and a spiral piece 20 is arranged on the drill bit 19, and the ring frame 18 is fixed to the motor frame 2, and the top of the drill bit 19 is slidably connected with the slave gear 21; the top of the drill bit 19 is located below the ring frame 18 and is fixedly connected with a top ring 33, and a gap is left between the top ring 33 and the ring frame 18, and a plurality of limiting edges 34 are fixedly connected to the top of the drill bit 19, and the limiting edges 34 are slidably connected with the slave gear 21, and the plurality of limiting edges 34 are in a ring array, and the plurality of limiting edges 34 penetrate the inside of the ring frame 18, and the left and right sides of the upper surface of the ring frame 18 are fixedly connected with the limiting ring 16 through a bracket.

[0037] More specifically, when the motor frame 2 moves upward, the motor frame 2 drives the collar frame 18 to move upward, and the collar frame 18 drives the drill bit 19 to move upward. When the motor frame 2 moves downward, the motor frame 2 drives the collar frame 18 to move downward, and the collar frame 18 drives the top ring 33 to move downward, and the top ring 33 drives the drill bit 19 to move downward. When the collar frame 18 moves up and down, the collar frame 18 drives the two compression cylinders 702 to slide up and down in the double cylinder 3. When the knocking block 506 repeatedly knocks the drill bit 19, the drill bit 19 has a downward impact force, so that the drill bit 19 is repeatedly displaced in the gap between the top ring 33 and the collar frame 18, and the width of the gap is greater than or The vertical displacement of the knocking block 506 is equal to that of the knocking block 506, thereby ensuring the range of the impact force of the drill bit 19. When the slave gear 21 rotates, the slave gear 21 drives the drill bit 19 to rotate through the limiting edge 34. Through the setting of the limiting ring 16, when the drill bit 19 moves up and down, the slave gear 21 is prevented from moving up and down. Through the setting of the spiral piece 20, when the drill bit 19 rotates forward, the spiral piece 20 is rotated forward through the drill bit 19, and the drill bit 19 is easier to embed in the building, and the drill bit 19 is not easy to fall off during the pull-out test. When the drill bit 19 is reversed, the spiral piece 20 is reversed through the drill bit 19, and the drill bit 19 in the building is easier to take out.

[0038] See also Fig. 9 An auxiliary plate 22 is fixedly connected to the inner side of the motor frame 2. The auxiliary plate 22 is sleeved on the surface of the rotating shaft 4 through a bearing. A main gear 23 is fixedly connected to the surface of the rotating shaft 4 and located below the auxiliary plate 22. The main gear 23 meshes with the slave gear 21.

[0039] More specifically, when the shaft 4 rotates, the auxiliary plate 22 is provided to increase the stability of the rotation of the shaft 4 , so that the shaft 4 drives the main gear 23 to rotate, and the main gear 23 drives the slave gear 21 to rotate.

[0040] See also Figure 2 , Fig. 9, Fig.10 , Fig.11 and Fig.12 , the left and right sides of the motor frame 2 are fixedly connected with a reset frame 24, the upper surface of the support plate 1 is fixedly connected with two guide rods 25, the guide rods 25 are slidably connected to the reset frame 24, a reset spring 26 is sleeved on the guide rod 25, the reset frame 24 acts on the top of the reset spring 26, the guide rod 25 and the top of the double cylinder 3 are fixedly connected with a connecting plate 27, the interior of the connecting plate 27 and the top of the double cylinder 3 are provided with an opening hole 28, the opening hole 28 is adapted to the cross bar 6 and the pressure rod 701; the support plate 1 is fixedly connected to the double cylinder 3, and a handle 32 is fixedly connected to one side of the motor frame 2, and the handle 32 is provided with anti-slip patterns.

[0041] More specifically, when the operating handle 32 raises or lowers the motor frame 2, the motor frame 2 drives the reset frame 24 to rise or fall, and makes the reset frame 24 slide smoothly on the guide rod 25, thereby ensuring the smooth lifting and lowering of the motor frame 2. In combination with the use of the reset spring 26, the reset spring 26 has an upward elastic force on the reset frame 24. When the motor frame 2 is pressed downward, the reset spring 26 is compressed. When the motor frame 2 is not pressed, the reset spring 26 resets the motor frame 2 by its own elastic force. During use, the device is operated by holding the handle 32 to perform inspection and processing on the building.

[0042] See also Figure 3 and Figure 6 A drill hole 29 is provided in the middle of the support plate 1, and the drill hole 29 is adapted to the drill bit 19. The port of the nozzle 706 extends inside the drill hole 29, and a telescopic cover 30 is sleeved on the surface of the drill bit 19. The telescopic cover 30 prevents the backflow of water or powder residue. A guide groove 31 is provided on the lower surface of the support plate 1 and at the edge of the drill hole 29.

[0043] More specifically, when the drill bit 19 is drilling, the telescopic cover 30 covers the drill bit 19 to prevent powder residue from splashing out, and the powder residue is discharged from the guide groove 31 or from the gap between the support plate 1 and the building. The support plate 1 has the function of blocking the powder residue to avoid affecting the operation.

[0044] In summary, the specific working principle and use process of the present invention are as follows: When drilling inspection on a building, it is necessary to drill a hole in the building and take out the internal samples of the building for inspection. Usually, when the drill bit 19 drills a hole in the building, the drill bit 19 does not have impact force and is prone to jamming, which is time-consuming and laborious. When the rotating shaft 4 rotates forward, the rotating shaft 4 drives the circular inner ring 501 and the two driving rollers 502 to rotate synchronously. There is a height difference between the two driving rollers 502. The rotation of the two driving rollers 502 causes the circular outer ring 503 and the telescopic shaft 505 to generate a swing angle at the same time. The swing angle generated by the telescopic shaft 505 acts on the knocking block 506, which moves the knocking block 506 up and down, causing the knocking block 506 to knock on the drill bit 19, thereby enhancing the impact force of the drill bit 19, avoiding the jamming of the drill bit 19, and ensuring smooth drilling.

[0045] When drilling inspection of a building, the drill bit 19 usually produces broken powder slag in the borehole during drilling. The powder slag is not easy to discharge, which affects the drilling, and the powder slag collection can be used as a sample for detection; when the knocking block 506 knocks the drill bit 19 up and down, the cross bar 6 drives the pressure rod 701 and the piston 703 to move downward synchronously, so that the piston 703 slides in the compression cylinder 702, and the compression cylinder 702 is pressurized. The internal gas of the compression cylinder 702 enters the bellows 705. At this time, the bellows 705 is pressurized, and the internal gas of the bellows 705 is ejected from the nozzle 706 to spray the powder slag in the borehole, thereby discharging the powder slag in the borehole, further ensuring smooth drilling.

[0046] When drilling inspection on a building, the drill bit 19 usually produces powder, slag and dust during drilling, which affects the operation and is not cleaned up properly. Water can be injected into the water tank 8 as needed. When the pressure rod 701 moves upward, the pressure rod 701 drives the piston 703 to move upward, so that negative pressure is generated inside the compression cylinder 702, and the water in the water tank 8 enters the compression cylinder 702 through the hose 12. In addition, the one-way solenoid valve 707 can prevent gas or liquid from flowing back. When the pressure rod 701 moves downward, the water in the compression cylinder 702 is sprayed out from the nozzle 706. Through the uninterrupted up and down movement of the pressure rod 701, the water in the water tank 8 is continuously sprayed out through the nozzle 706, which not only rinses the powder in the hole, but also prevents the powder and slag from splashing.

[0047] When drilling inspection is performed on a building, the drill bit 19 needs to be drilled into the interior of the building to perform a pull-out test on the building to determine whether the internal strength of the building meets the standard; only the one-way solenoid valve 707 needs to be closed, and when the pressure rod 701 moves downward, the pressure rod 701 drives the piston 703 to move downward, and the piston 703 further increases the internal pressure of the compression cylinder 702. At this time, the internal hydraulic pressure or air pressure of the compression cylinder 702 enters the bellows 705, causing the bellows 705 to generate an expansion force, so that the circular plate 704 and the compression cylinder 702 have an upward push force, and the compression cylinder 702 drives the ring frame 18 and the limit ring 16 to have an upward trend, and then the limit ring 16 drives the drill bit 19 to have an upward force, and the building is subjected to a pull-out test through the upward force of the drill bit 19, thereby determining the internal strength of the building.

[0048] When inspecting a building project, check whether the levelness of the building meets the standard; through the coordinated arrangement of the two water tanks 8 and the pipe 9, it is only necessary to open the screw cap 11 to inject water into the water tank 8 as needed, and the two water tanks 8 are interconnected through the pipe 9. It is only necessary to contact the support plate 1 with the top of the building, and by observing the scale lines on the transparent glass 10, it is determined whether the liquid levels of the two water tanks 8 are at the same scale value, thereby determining the levelness of the building.

[0049] When inspecting a building, it is necessary to perform a knocking treatment on the surface of the building to determine whether the surface hardness of the building meets the standard, whether it is peeling or fragile, etc.; when the servo motor 14 is reversed and started, the output end of the servo motor 14 causes the main bevel gear 15 to rotate, and the main bevel gear 15 drives the rotating shaft 4 to rotate. Through the rotation of the rotating shaft 4, the slave bevel gear 17, the main gear 23 and the matching arrangement of the slave gear 21, the rotating shaft 4 drives the slave gear 21 to rotate, and then the slave gear 21 drives the drill bit 19 to reverse. When the drill bit 19 reverses, it is difficult for the drill bit 19 to drill into the interior of the building. Similarly, when the servo motor 14 is reversed and started, the knocking block 506 knocks the drill bit 19, and then the drill bit 19 has a knocking force on the surface of the building to determine whether the surface hardness of the building meets the standard, whether it is peeling or fragile, etc.
