Description

Technical Field

[0001] The invention relates to the field of building components, in particular to a drilling device for quality inspection of building components. Background Art

[0002] The background technology of building component quality inspection is mainly rooted in ensuring the long-term safety and stability of building structures and meeting increasingly stringent building codes and standards. With the acceleration of urbanization and the continuous expansion of the scale of construction projects, the quality inspection of building components has become a key link in the quality control of construction projects. Traditionally, the quality inspection of building components relies on manual observation and simple physical tests, such as knocking tests, visual inspections, etc. Although these methods are simple and easy to implement, they are limited by people's subjective judgment and experience, and it is difficult to comprehensively and accurately evaluate the intrinsic quality of building components. With the advancement of science and technology, especially the development of non-destructive testing technology, the means of building component quality inspection have been greatly enriched and improved. The current building component quality inspection drilling device is designed to perform quality inspection tasks by drilling and sampling precast concrete panels. However, in actual operation, the device usually first uses a clamp to fix the precast concrete panel, and then uses a drill tube to perform drilling operations. However, before the drill tube has not formed a borehole on the surface of the precast concrete panel, due to the lack of appropriate limit constraints, the rotating drill tube may swing left and right when it starts drilling at the top of the precast concrete panel. This swing increases the risk of damage to the connection between the drill tube and the drive shaft to a certain extent. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the background technology and to propose a drilling device for quality inspection of building components.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a drilling device for quality inspection of building components, comprising a base plate, a mounting frame 1 is welded on the top of the base plate, an electric push rod is fixedly installed on the top of the mounting frame 1, a mounting plate is fixedly installed on the telescopic end of the electric push rod, a mounting frame 2 is welded on the bottom of the mounting plate, a drill barrel is rotatably connected to the top of the mounting frame 2, a piston plate is rotatably connected to the outer peripheral wall of the drill barrel, two symmetrical sleeves are welded on the bottom of the mounting plate, sleeve rods are slidably arranged in the inner cavities of the two sleeves, springs are arranged in the inner cavities of the two sleeves, and the two springs are respectively connected between the top of the corresponding sleeve inner cavity and the top of the corresponding sleeve rod, an outer cylinder is welded between the bottoms of the two sleeve rods, and the outer ring wall of the piston plate abuts against the inner ring wall of the outer cylinder, and air bags are sleeved on the outer peripheral walls of the two sleeve rods. An annular filter is fixedly installed on the inner ring wall of the outer cylinder, and an air supply pipe is connected between the inner cavity of the outer cylinder and the two air bags. The downward movement of the mounting plate will drive the sleeve, sleeve rod, spring, air bag and outer cylinder to move downward, so that the bottom of the outer cylinder abuts against the top of the precast concrete slab; as the sleeve continues to move downward, the arranged spring is compressed, and the compressed spring will apply a reaction force to the sleeve rod and the outer cylinder, so that the bottom of the sleeve is tightly abutted against the top of the precast concrete slab, so as to enhance the stability of the drill barrel during drilling; in addition, the downward movement of the drill barrel will drive the piston plate to move downward, and the piston plate will push the gas at its bottom into the inner cavity of the outer cylinder through the annular filter. In this process, the dust generated when the drill barrel is drilling will adhere to the outer surface of the annular filter under the action of the airflow, so as to collect the dust, thereby reducing the probability of subsequent dust escaping into the external space.

[0005] In the above-mentioned drilling device for quality inspection of building components, a rotating column is rotatably connected to the inner ring wall of the drill barrel, a connecting rod is welded to one side wall of the mounting frame, a second air pipe is fixedly installed at the bottom of the connecting rod, a second solenoid valve is fixedly installed on the wall of the second air pipe, a plug rod is connected to the side of the second air pipe close to the drill barrel, the inner cavity of the plug rod is divided into an air outlet cavity and a pressurizing cavity, and the second air pipe is connected to the pressurizing cavity, and an air hole 1 and an air hole 2 connected to the air outlet cavity are opened on the outer ring wall of the plug rod.

[0006] In the above-mentioned drilling device for quality inspection of building components, a limit tube is welded on the inner wall of the drill barrel, and an air hole three is opened on the outer ring wall of the limit tube. The downward movement of the drill barrel will drive the limit tube inside it to move downward. When the air hole three on the side wall of the limit tube is aligned with the air hole one of the air outlet cavity, the gas originally inhaled inside the airbag flows back to the inner cavity of the outer tube through the air supply pipe one again, and then the air flow passes through the annular filter screen into the inner cavity of the drill barrel, and finally the gas is discharged from the inner cavity of the drill barrel through the air hole three, the air hole one and the air hole two in turn. In this process, the dust adhered to the outer surface of the annular filter screen is combined with the cooling water used for cooling the drill barrel under the recoil action of the gas, so as to perform secondary dust treatment, which further reduces the probability of subsequent dust escaping into the external space.

[0007] In the above-mentioned drilling device for quality inspection of building components, an air hole four connected to the pressurized chamber is opened on the outer ring wall of the insertion rod, a telescopic hose is connected to the side of the air pipe two away from the insertion rod, and a telescopic hose is connected to the air pipe three on the side away from the air pipe two.

[0008] In the above-mentioned drilling device for inspecting the quality of building components, two symmetrical sealing rods are welded to the bottom of the piston plate, one of the sealing rods has an air hole five at the top, and the air hole five penetrates the piston plate upward and is connected to the air pipe three-phase.

[0009] In the above-mentioned drilling device for quality inspection of building components, a rotating block ring is rotatably connected to the outer ring wall of the drill barrel, a sealing plate is welded on the inner ring wall of the outer barrel, and the rotating ring is slidably connected to the sealing plate, and two symmetrical air holes six are opened on the top of the sealing plate. As the piston plate continues to move downward, the arranged piston plate will drive the sealing rod to be inserted into the air hole three. At this time, a closed space is formed between the piston plate and the sealing plate. At the same time, as the limit tube moves downward, the idle area in the upper half of the limit tube is displaced to the position of the air hole four. At the same time, the arranged solenoid valve one and the arranged solenoid valve two are opened; as the piston plate moves further downward, the gas between the arranged piston plate and the sealing plate enters the inner cavity of the drill barrel through the air hole five, the air inlet pipe three, the telescopic hose, the air inlet pipe two, the pressurizing chamber and the air hole four in turn.

[0010] In the above-mentioned drilling device for quality inspection of building components, a motor is fixedly installed on the side wall of the second mounting frame, a gear one is fixedly installed on the output end of the motor, a gear two meshing with the gear one is fixedly sleeved on the outer ring wall of the drill barrel, and an electric push rod is provided to drive the mounting plate, the second mounting frame and the drill barrel to move downward. At the same time, the motor drives the gear one to rotate, and the gear one drives the gear two and the drill barrel to rotate, so as to perform sampling operations on precast concrete slabs.

[0011] In the above-mentioned drilling device for quality inspection of building components, a drainage pipe is arranged on the outer ring wall of the outer cylinder, and the drainage pipe extends to the inner ring wall of the outer cylinder, and a solenoid valve is fixedly installed on the wall of the drainage pipe.

[0012] Compared with the existing technology, the advantages of the drilling device for building component quality inspection are:

[0013] 1. As the sleeve continues to move downward, the spring is compressed, and the compressed spring applies a reaction force to the sleeve rod and the outer tube, so that the bottom of the sleeve is closely abutted against the top of the precast concrete slab, thereby enhancing the stability of the drill tube during drilling; the gas entering the inner cavity of the outer tube enters the air bag through the air pipe, so that the air bag inhales and expands, and the expanded air bag applies a downward force to the outer tube, so that the bottom of the outer tube is more closely abutted against the top of the precast concrete slab, which further enhances the stability of the drill tube during drilling;

[0014] 2. The downward movement of the drill tube will drive the piston plate to move downward, and the piston plate will push the gas at its bottom through the annular filter into the inner cavity of the outer tube. During this process, the dust generated by the drill tube will adhere to the outer surface of the annular filter under the action of the airflow, so as to collect the dust and reduce the probability of subsequent dust escaping into the external space;

[0015] 3. The gas originally inhaled inside the airbag flows back to the inner cavity of the outer tube through the gas pipe, and then the airflow passes through the annular filter and enters the inner cavity of the drill tube. The dust adhering to the outer surface of the annular filter combines with the cooling water used for cooling the drill tube under the recoil of the gas, so as to perform secondary dust treatment, which further reduces the probability of subsequent dust escaping into the external space;

[0016] 4. As the piston plate moves further downward, the gas between the piston plate and the sealing plate enters the inner cavity of the drill barrel through the air hole five, the air inlet pipe three, the telescopic hose, the air inlet pipe two, the pressurizing chamber and the air hole four in sequence, and then the air flow pushes the cooling water to flow into the drain pipe at an accelerated speed, thereby enhancing the cooling effect of the cooling water on the bottom of the drill barrel.

[0032] Furthermore, a piston plate 7 is rotatably connected to the outer peripheral wall of the drill tube 6, two symmetrical sleeves 8 are welded to the bottom of the mounting plate 4, and sleeve rods 9 are slidably arranged in the inner cavities of the two sleeves 8. Springs 10 are arranged in the inner cavities of the two sleeves 8, and the two springs 10 are respectively connected between the top of the inner cavity of the corresponding sleeve 8 and the top of the corresponding sleeve rod 9, and an outer cylinder 11 is welded between the bottoms of the two sleeve rods 9, and the outer ring wall of the piston plate 7 is in contact with the inner ring wall of the outer cylinder 11; wherein, a limiting groove is arranged on the inner wall of the outer cylinder 11, and a A limit strip is arranged on the outer wall of the piston plate 7, and the limit strip is slidably arranged in the limit groove, so that the piston plate 7 can only slide up and down along the inner wall of the outer cylinder 11; the outer peripheral walls of the two sleeve rods 9 are sleeved with air bags 12, and an annular filter screen 13 is fixedly installed on the inner ring wall of the outer cylinder 11. An air delivery pipe 14 is connected between the inner cavity of the outer cylinder 11 and the two air bags 12. The downward movement of the mounting plate 4 will drive the sleeve 8, the sleeve rod 9, the spring 10, the air bag 12 and the outer cylinder 11 to move downward, so that the bottom of the outer cylinder 11 abuts against the prefabricated The top of the concrete slab 39; as the sleeve 8 continues to move downward, the spring 10 is compressed, and the compressed spring 10 applies a reaction force to the sleeve rod 9 and the outer tube 11, so that the bottom of the sleeve 8 is closely abutted against the top of the precast concrete slab 39, thereby enhancing the stability of the drill tube 6 during drilling; in addition, the downward movement of the drill tube 6 will drive the piston plate 7 to move downward, and the piston plate 7 will push the gas at its bottom through the annular filter 13 into the inner cavity of the outer tube 11. In this process, the dust generated when the drill tube 6 is drilling will adhere to the outer surface of the annular filter 13 under the action of the airflow, so as to collect the dust and reduce the probability of subsequent dust escaping to the external space; the gas entering the inner cavity of the outer tube 11 enters the air bag 12 through the air supply pipe 14, so that the air bag 12 is inhaled and expanded, and the expanded air bag 12 applies a downward force to the outer tube 11, so that the bottom of the outer tube 11 is more closely abutted against the top of the precast concrete slab 39, which further enhances the stability of the drill tube 6 during drilling.

[0033] Furthermore, a rotating column 15 is rotatably connected to the inner ring wall of the drill tube 6, a connecting rod 16 is welded to the side wall of the mounting frame 2, an air pipe 17 is fixedly installed at the bottom of the connecting rod 16, and an electromagnetic valve 18 is fixedly installed on the wall of the air pipe 17. A plug rod 19 is connected to the side of the air pipe 17 close to the drill tube 6, and the inner cavity of the plug rod 19 is separated into an air outlet cavity 20 and a pressurizing cavity 21, and the air pipe 17 is connected to the pressurizing cavity 21, and an air hole 12 and an air hole 23 connected to the air outlet cavity 20 are provided on the outer ring wall of the plug rod 19, a limiting tube 24 is welded to the inner side wall of the drill tube 6, and an air hole 3 25 is provided on the outer ring wall of the limiting tube 24. The downward movement of the drill tube 6 will drive the limiting tube 24 inside it to move downward. When the air hole 3 25 on the side wall of the limiting tube 24 is aligned with the air hole 1 22 of the air outlet cavity 20, The gas originally inhaled inside the airbag 12 flows back to the inner cavity of the outer tube 11 through the air supply pipe 14 again, and then the airflow passes through the annular filter 13 and enters the inner cavity of the drill barrel 6. Finally, the gas is discharged from the inner cavity of the drill barrel 6 through the air hole 3 25, the air hole 1 22 and the air hole 2 23 in sequence. In this process, the dust adhering to the outer surface of the annular filter 13 combines with the cooling water used for cooling the drill barrel 6 under the recoil effect of the gas, so as to perform secondary dust treatment, which further reduces the probability of subsequent dust escaping into the external space; it should be noted that a water adding hole 40 is opened through the top of the rotating column 15, and the water adding hole 40 can be connected to the external cooling water pipe, and then cooling water is added to the inner cavity of the drill barrel 6 through the external cooling water pipe and the water adding hole 40, so as to cool the drill barrel 6.

[0034] Furthermore, an air hole 26 connected to the pressurized chamber 21 is provided on the outer ring wall of the plug rod 19, a telescopic hose 27 is connected to the side of the gas pipe 217 away from the plug rod 19, and a telescopic hose 27 is connected to the side of the gas pipe 217 away from the gas pipe 217. Two symmetrical sealing rods 29 are welded to the bottom of the piston plate 7, and an air hole 5 30 is provided on the top of one of the sealing rods 29, and the air hole 5 30 penetrates the piston plate 7 upward and is connected to the gas pipe 3 28. A rotating block ring 31 is rotatably connected to the outer ring wall of the drill tube 6, a sealing plate 32 is welded to the inner ring wall of the outer tube 11, and the rotating ring is slidably connected to the sealing plate 32, and two symmetrical air holes 6 33 are provided on the top of the sealing plate 32, and a drain pipe 37 is provided on the outer ring wall of the outer tube 11, and the drain pipe 37 extends to the inner ring wall of the outer tube 11, so that the water can be discharged. An electromagnetic valve 38 is fixedly installed on the wall of the tube 37. As the piston plate 7 continues to move downward, the piston plate 7 will drive the sealing rod 29 to be inserted into the air hole 3 25. At this time, a closed space is formed between the piston plate 7 and the sealing plate 32. At the same time, as the limit tube 24 moves downward, the idle area in the upper half of the limit tube 24 is displaced to the position of the air hole 4 26. At the same time, the electromagnetic valve 38 and the electromagnetic valve 2 18 are opened; as the piston plate 7 moves further downward, the gas between the piston plate 7 and the sealing plate 32 passes through the air hole 5 30, the air inlet pipe 3, the telescopic hose 27, the air inlet pipe 2, the pressurized chamber 21 and the air hole 4 26 in turn into the inner cavity of the drill barrel 6, and then the air flow drives the cooling water to accelerate the flow into the drain pipe 37, thereby enhancing the cooling effect of the cooling water on the bottom of the drill barrel 6.

[0035] Working principle: When in use, the precast concrete slab 39 to be sampled and tested is placed on the bottom plate 1, and then the precast concrete slab 39 is limited and fixed by means of the clamping piece on the bottom plate 1; when sampling, the electric push rod 3 drives the mounting plate 4, the second mounting frame 5 and the drill tube 6 to move downward, and at the same time, the motor 34 drives the gear 1 35 to rotate, and the gear 1 35 drives the gear 2 36 and the drill tube 6 to rotate, so as to perform sampling operation on the precast concrete slab 39;

[0036] In the above process, the downward movement of the mounting plate 4 will drive the sleeve 8, the sleeve rod 9, the spring 10, the airbag 12 and the outer tube 11 to move downward, so that the bottom of the outer tube 11 abuts against the top of the precast concrete slab 39; as the sleeve 8 continues to move downward, the arranged spring 10 is compressed, and the compressed spring 10 will apply a reaction force to the sleeve rod 9 and the outer tube 11, so that the bottom of the sleeve 8 is tightly abutted against the top of the precast concrete slab 39, so as to enhance the stability of the drill tube 6 during drilling; in addition, the downward movement of the drill tube 6 will drive the piston plate 7 to move downward, and the piston plate 7 will push the gas at its bottom through the annular filter 13 into the inner cavity of the outer tube 11. In this process, the dust generated when the drill tube 6 is drilling will be removed by the action of the airflow. Adhere to the outer surface of the annular filter 13 to collect dust, thereby reducing the probability of subsequent dust escaping to the external space; it should be noted that a sealing rubber ring is provided at the bottom of the outer cylinder 11, and the closed space formed by the outer cylinder 11 and the piston plate 7 makes it difficult for dust to escape outward through the gap between the bottom of the outer cylinder 11 and the top of the precast concrete plate 39; the gas entering the inner cavity of the outer cylinder 11 enters the airbag 12 through the air pipe 14, so that the airbag 12 inhales and expands, and the expanded airbag 12 applies a downward force to the outer cylinder 11, so that the bottom of the outer cylinder 11 and the top of the precast concrete plate 39 are more closely abutted, which further enhances the stability of the drill tube 6 during drilling;

[0037] The downward movement of the drill tube 6 will drive the limiting tube 24 inside it to move downward. When the air hole 3 25 on the side wall of the limiting tube 24 is aligned with the air hole 1 22 of the air outlet cavity 20, the gas originally inhaled in the air bag 12 will flow back to the inner cavity of the outer tube 11 through the air supply pipe 1 14 again, and then the air flow passes through the annular filter 13 to enter the inner cavity of the drill tube 6, and finally the gas passes through the air hole 3 25, the air hole 1 22 and the air hole 2 23 in sequence to be discharged from the inner cavity of the drill tube 6. In this process, the dust adhered to the outer surface of the annular filter 13 is combined with the cooling water used for cooling the drill tube 6 under the recoil effect of the gas, so as to perform secondary dust treatment, which further reduces the probability of subsequent dust escaping to the external space; it should be noted that a water adding hole 40 is provided through the top of the rotating column 15, and the water adding hole 40 can be connected to the external cooling water pipe, and then cooling water is added to the inner cavity of the drill tube 6 through the external cooling water pipe and the water adding hole 40, so as to cool the drill tube 6;

[0038] As the piston plate 7 continues to move downward, the piston plate 7 will drive the sealing rod 29 to be inserted into the air hole three 25. At this time, a closed space is formed between the piston plate 7 and the sealing plate 32. At the same time, as the limit tube 24 moves downward, the idle area of ​​the upper half of the limit tube 24 is displaced to the position of the air hole four 26. At the same time, the solenoid valve one 38 and the solenoid valve two 18 are opened; as the piston plate 7 moves further downward, the gas between the piston plate 7 and the sealing plate 32 passes through the air hole five 30, the air inlet pipe three, the telescopic hose 27, the air inlet pipe two, the pressurizing chamber 21 and the air hole four 26 in turn into the inner cavity of the drill barrel 6, and then the air flow drives the cooling water to accelerate the flow into the drain pipe 37, thereby enhancing the cooling effect of the cooling water on the bottom of the drill barrel 6.
