Description

Technical Field

[0001] The utility model relates to the technical field of pipe detection, in particular to a pressure resistance performance detection device for building pipes. Background Art

[0002] Building pipes are a type of piping material widely used in the construction field, mainly used to transport water, gas, electricity and other resources. They have the characteristics of pressure bearing, corrosion resistance, heat resistance, and good sealing, ensuring the safe transportation of fluids or gases in buildings. The building pipe pressure resistance performance testing device is a device specially used to test the pressure resistance performance of building pipes under high pressure environments. Its main purpose is to ensure that the pipes can maintain their structural integrity and sealing when subjected to working pressure to meet the requirements of building safety and use.

[0003] Common pressure resistance performance testing devices for building pipes generally use a cylinder to drive the movement of a pressure plate to apply pressure to the surface of the pipe to achieve the purpose of testing. However, this method only tests the outside of the pipe when applying pressure, and the inside of the pipe cannot be effectively tested for external expansion pressure, resulting in a single data for pipe pressure testing, which cannot meet the working requirements of pipe testing. Therefore, a pressure resistance performance testing device for building pipes is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides a device for testing the pressure resistance of building pipes to solve the technical problem that when pressure is applied, only the outside of the pipe is simply tested, resulting in single data for the pipe pressure test.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for testing the pressure resistance performance of building pipes, comprising:

[0008] A base, a card seat is installed on the top of the base, vertical plates are installed on the left and right sides of the top of the base, a first motor is installed in the middle of the inner side of the vertical plate, and connecting columns are installed circumferentially on the inner side of the vertical plate;

[0009] A mounting plate is mounted on the inner end of the connecting column, bearing sleeves are coaxially mounted on both the left and right sides of the mounting plate, a driving shaft is inserted into the position inside the mounting plate located inside the bearing sleeve, and the outer ends of the driving shaft are connected to the rotor of the first motor;

[0010] The driving disc is installed outside the driving shaft at the middle position inside the installation disc cavity. Clamping blocks are installed on the outer sides of the inner cavities of the installation disc. Inner support rods are inserted into the clamping blocks. Transmission grooves are circumferentially formed inside the driving disc, and insertion shafts are inserted into the transmission grooves.

[0011] The mounting frame is installed at the middle position at the rear of the base. A hydraulic cylinder is installed on the upper side of the front part of the mounting frame, and a pressing plate is installed at the bottom end of the hydraulic cylinder.

[0012] Preferably, the number of the clamping blocks and the inner support rods is 3 - 5 groups. The outer ends of the inner support rods are all arranged in a spherical structure. Angle codes are installed at the inner ends of the inner support rods. The inner sides of the angle codes are connected to the left and right ends of the insertion shafts respectively, which facilitates the up - and - down movement of the inner support rods pushed by the insertion shafts when the driving disc rotates.

[0013] Preferably, a second motor is installed at the left end of the base. Chute grooves are opened on the left and right sides inside the base. Slide blocks are inserted into the chute grooves, and the tops of the slide blocks are connected to the bottoms of the vertical plates, enabling the slide blocks to move left and right inside the chute grooves, thereby enabling the vertical plates to be adjusted left and right, which facilitates the detection of pipes with different lengths.

[0014] Preferably, the rotors of the second motors are coaxially connected to first lead screws. The first lead screws penetrate through the inside of the slide blocks. The shapes of the chute grooves and the slide blocks are both trapezoidal, which improves the stability of the slide blocks when moving left and right.

[0015] Preferably, side plates are connected to the left and right sides at the rear of the base. A third motor is installed on the outer side of the left side plate. The rotor of the third motor is coaxially connected to a second lead screw. The second lead screw penetrates through the inside of the mounting frame. The rotation of the second lead screw can be driven by the third motor, thereby enabling the mounting frame to move left and right, which facilitates the adjustment of the left - and - right positions of the hydraulic cylinder and the pressing plate, enabling the pressure detection of different positions on the surface of the pipe.

[0016] Preferably, guide rods are inserted into the positions above and below the second lead screw inside the mounting frame. The left and right ends of the guide rods are connected to the corresponding positions on the inner sides of the side plates. An insertion block is installed on the lower side of the front part of the mounting frame, and a through - groove is opened at the position corresponding to the insertion block at the rear of the base, which improves the stability of the mounting frame when moving left and right.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a device for detecting the pressure resistance performance of building pipes, having the following beneficial effects:

[0019] The pressure resistance performance detection device for building pipes drives the rotation of the drive shaft through the first motor, so that the movement of the insertion shaft can be driven through the transmission disc and the transmission groove, enabling the synchronous expansion of the inner support rod, and then the internal pressure of the pipe can be detected. That is, when the first motors on both the left and right sides drive the drive shaft to rotate, the inner support rod can normally limit both sides of the inside of the pipe. At this time, the hydraulic cylinder drives the pressure plate to move downward under overpressure, and the external pressure of the pipe can be detected. Conversely, when the hydraulic cylinder drives the pressure plate to move under normal pressure, the outside of the pipe can be limited. And at this time, when the first motor drives the drive shaft to rotate beyond the threshold, the inner support rod can detect the pressure on both sides of the inside of the pipe, improving the diversity of the pipe detection data. At the same time, because the inner support rod and the pressure plate exchange the limiting function, the problem of inaccurate data caused by the loosening of the pipe during detection will not occur.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides a technical solution, a device for detecting the pressure resistance performance of building pipes, including a base 1, a clamping seat 2, a vertical plate 3, a first motor 4, a connecting column 5, a mounting disc 6, a bearing sleeve 7, a driving shaft 8, a transmission disc 9, a clamping block 10, an inner support rod 11, an angle code 111, an insertion shaft 112, a transmission groove 12, a second motor 13, a first lead screw 14, a sliding groove 15, a sliding block 16, a side plate 17, a third motor 18, a second lead screw 19, a mounting frame 20, a guide rod 21, a hydraulic cylinder 22 and an insertion block 23:

[0030] Please refer to Figure 1 , a clamping seat 2 is installed on the top of the base 1, vertical plates 3 are installed on both the left and right sides of the top of the base 1. Please refer to Figure 2 , first motors 4 are installed in the middle of the inner sides of the vertical plates 3, and connecting columns 5 are circumferentially installed on the inner sides of the vertical plates 3;

[0031] A mounting disc 6 is installed at the inner end of the connecting column 5. Bearing sleeves 7 are coaxially installed on both the left and right sides of the mounting disc 6. A driving shaft 8 is inserted at a position inside the mounting disc 6 and inside the bearing sleeves 7, and the outer ends of the driving shaft 8 are connected to the rotors of the first motors 4;

[0032] Please refer to Figure 3 , a transmission disc 9 is installed at a position in the middle of the inner cavity of the mounting disc 6 outside the driving shaft 8. Clamping blocks 10 are installed on the outer sides of the inner cavity of the mounting disc 6. Inner support rods 11 are inserted into the clamping blocks 10. A transmission groove 12 is circumferentially opened inside the transmission disc 9. Insertion shafts 112 are inserted into the transmission groove 12. The number of the clamping blocks 10 and the inner support rods 11 is 3 - 5 groups. The outer ends of the inner support rods 11 are all set as spherical structures. Please refer to Figure 4 , angle codes 111 are installed at the inner ends of the inner support rods 11, and the inner sides of the angle codes 111 are connected to the left and right ends of the insertion shafts 112;

[0033] Please refer to Figure 1 , a mounting frame 20 is installed at the middle position of the rear part of the base 1. A hydraulic cylinder 22 is installed on the upper side of the front part of the mounting frame 20. A pressing plate 222 is installed at the bottom end of the hydraulic cylinder 22. Please refer to Figure 5, a second motor 13 is installed at the left end of the base 1. Chute 15s are provided on both the left and right sides inside the base 1. Sliders 16 are inserted into the chutes 15, and the tops of the sliders 16 are connected to the bottom of the vertical plate 3. The rotors of the second motors 13 are coaxially connected to first lead screws 14, and the first lead screws 14 penetrate through the insides of the sliders 16. The chutes 15 and the sliders 16 are both trapezoid-shaped. By driving the rotation of the drive shaft 8 with the first motor 4, the movement of the insertion shaft 112 can be driven through the transmission disc 9 and the transmission groove 12, so that the outward expansion of the inner support rod 11 can be synchronously promoted, and then the internal pressure of the pipe can be detected. That is, when the first motors 4 on both the left and right sides drive the drive shaft 8 to rotate, the inner support rod 11 can normally limit both sides inside the pipe. At this time, the hydraulic cylinder 22 drives the pressure plate 222 to perform a downward movement under overpressure, and the external pressure of the pipe can be detected. On the contrary, when the hydraulic cylinder 22 drives the pressure plate 222 to perform a movement under normal pressure, the outside of the pipe can be limited. And at this time, when the first motor 4 drives the drive shaft 8 to rotate beyond the threshold, the inner support rod 11 can detect the pressure on both sides inside the pipe, improving the diversity of the pipe detection data. At the same time, because the inner support rod 11 and the pressure plate 222 exchange the limiting function, the problem of inaccurate data caused by the loosening of the pipe during detection will not occur;

[0034] Please refer to Figure 6 , side plates 17 are connected to both the left and right sides at the rear of the base 1. A third motor 18 is installed on the outside of the left side plate 17. The rotor of the third motor 18 is coaxially connected to a second lead screw 19. The second lead screw 19 penetrates through the inside of the mounting frame 20. Guide rods 21 are inserted at the positions above and below the second lead screw 19 inside the mounting frame 20. The left and right ends of the guide rods 21 are connected to the corresponding positions on the inner side of the side plates 17. Please refer to Figure 7 , a plug 23 is installed on the lower side of the front part of the mounting frame 20, and a through groove is provided at the position corresponding to the plug 23 at the rear of the base 1.

[0035] In this solution, the rotation of the drive shaft 8 is driven by the first motor 4, so that the movement of the insertion shaft 112 can be driven through the transmission disc 9 and the transmission groove 12, enabling the synchronous outward expansion of the inner support rod 11, and then the internal pressure of the pipe can be detected. That is, when the first motors 4 on both the left and right sides drive the drive shaft 8 to rotate, the inner support rod 11 can normally limit both sides of the inside of the pipe. At this time, the hydraulic cylinder 22 drives the pressure plate 222 to move downward under overpressure, and the external pressure of the pipe can be detected. Conversely, when the hydraulic cylinder 22 drives the pressure plate 222 to move under normal pressure, the outside of the pipe can be limited. And at this time, when the first motor 4 drives the drive shaft 8 to rotate beyond the threshold, the inner support rod 11 can detect the pressure on both sides of the inside of the pipe, improving the diversity of the pipe detection data. At the same time, since the inner support rod 11 and the pressure plate 222 exchange the limiting function, the problem of inaccurate data caused by the loosening of the pipe during detection will not occur.
