Description

Technical Field

[0001] The present invention belongs to the technical field of steel bar detection, and specifically relates to a steel bar detection device for construction engineering. Background Art

[0002] Construction engineering refers to a systematic engineering activity of building various buildings, structures and their ancillary facilities through scientific planning, design, construction and management. Its purpose is to create a spatial environment that meets the use function, is safe and reliable, economically reasonable and coordinated with the environment. The detection of steel bars in construction engineering is a key link to ensure the safety and durability of building structures. By systematically testing the mechanical properties, chemical compositions, dimensions and specifications of steel bars, it is verified whether they meet the design requirements and relevant standards, and whether the properties such as strength and ductility of steel bars meet the design load requirements, so as to avoid structural cracking, deformation or even collapse caused by unqualified steel bars, and ensure that the steel bar materials meet the national or industry standards. The main items of steel bar detection include mechanical property detection, chemical composition analysis, dimension and appearance detection, and durability detection. Among them, the mechanical property detection includes tensile test, bending test and reverse bending test. Among them, the tensile test is to determine the yield strength, tensile strength and elongation after fracture. Therefore, a steel bar detection device for construction engineering is needed.

[0003] The existing steel bar detection devices for construction engineering have certain drawbacks when in use. When the existing steel bar detection devices for construction engineering are in use, they usually clamp the steel bars through a clamping component, and then the hydraulic cylinder controls the clamping component to stretch the steel bars for detection. However, the hydraulic cylinder usually moves back to stretch the steel bars. Since the hydraulic cylinder pushes the piston to move through liquid pressure to generate tensile force, when the steel bar is stretched to fracture, the suddenly released stress may impact the hydraulic cylinder. Especially during the return stroke, the hydraulic cylinder needs to retract quickly. At this time, if the tensile force becomes zero instantly when the steel bar fractures, the piston of the hydraulic cylinder continues to retract due to inertia, resulting in a sudden change in the oil flow rate (the pressure fluctuation reaches ±30%), triggering hydraulic shock, which may damage the hydraulic cylinder due to inertia or reaction force, thus causing economic losses to people and unable to meet people's needs.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0041] When performing tensile testing on building steel bars, select the measuring range according to the nominal diameter of the steel bar. For example, for Φ20mm deformed steel bars with a tensile strength ≥ 400MPa, a measuring range ≥ 600kN should be selected, and randomly cut from the same batch of steel bars, with at least 3 specimens taken from each batch. During testing, it is necessary to remove the oil stain, rust or oxide layer on the surface of the steel bar to avoid affecting the clamping force.

[0042] In the present invention, the clamping assembly includes a first clamping seat 7 fixedly installed at the upper end of the detection base 1, a second clamping seat 8 movably arranged on the other side of the upper end of the detection base 1, and clamping structures 9 respectively arranged on the first clamping seat 7 and the second clamping seat 8. The first clamping seat 7 and the second clamping seat 8 are arranged in alignment, and clamping grooves for inserting the steel bar are provided on both the first clamping seat 7 and the second clamping seat 8.

[0043] In the present invention, the clamping structure 9 includes clamping blocks 10 symmetrically arranged in the clamping groove and a first driving structure 11 for controlling the horizontal movement of the clamping blocks 10. A first groove is formed on the inner side surface of the clamping blocks 10, and a plurality of groups of clamping strips 12 for improving the clamping force of the steel bar are arranged in the first groove. Vibration isolation structures for vibration damping and protection of the first driving structure 11 are arranged inside both the first clamping seat 7 and the second clamping seat 8.

The second driving structure 13 is set as a hydraulic cylinder, and when the second driving structure 13 squeezes the detection block 2, the steel bar is controlled to perform tensile testing through the second clamping seat 8, avoiding damage to the second driving structure 13 when the steel bar breaks.

[0045] In the present invention, the detection mechanism further includes a detection pointer 15 disposed on the outer surface of the detection block 2 and a detection ruler 16 detachably mounted on the upper end surface of the detection base 1 and aligned with the detection pointer 15. The detection ruler 16 is made transparent and is provided with scale values for displaying the moving distance of the detection block 2. The detection mechanism further includes a signal receiving block 17 on the outer side of another group of detection blocks 2 and a laser rangefinder 18 detachably mounted on the outer surface of the protection base 4 and aligned with the signal receiving block 17.

[0046] In summary, the two ends of the threaded steel bar to be detected are respectively inserted into the first clamping seat 7 and the second clamping seat 8. The first driving structure 11 is started to drive the clamping block 10 to move, so that the clamping block 10 and the clamping strip 12 cooperate to clamp and fix the two ends of the steel bar. The second driving structure 13 is started, and the detection block 2 is driven to move through the pressure sensor 14, so as to perform a tensile test on the steel bar. Before the detection block 2 moves, the detection pointer 15 is aligned with the detection ruler 16 and this value is recorded. The laser rangefinder 18 is started, so that the signal receiving block 17 receives the signal emitted by the laser rangefinder 18 and records this value. After the detection structure 3 finishes detecting the steel bar, the values of the detection pointer 15 and the laser rangefinder 18 are recorded, so as to obtain the result of the tensile test of the threaded steel bar.

[0047] Embodiment 2

[0048] Refer to Figure 1 - Figure 6 This is the second embodiment of the present invention. Among them, in the present invention, the detection mechanism further includes a first protection block 21 disposed outside the limit block 6 and fixedly connected to the outer side surface of the second clamping seat 8, and a second protection block 22 disposed on the limit seat 5 and aligned with the first protection block 21. A limit groove 23 for inserting the limit block 6 is provided on the limit seat 5. Third protection blocks 56 for buffer protection are provided on both the detection block 2 and the protection base 4.

[0049] The locking assembly includes a moving structure 24 symmetrically and movably disposed on the limit seat 5 and capable of contacting the limit block 6, a first locking structure 25 respectively disposed on the upper and lower sides of the moving structure 24 and capable of locking the limit block 6, a transmission structure 26 for transmitting the connection between the moving structure 24 and the first locking structure 25, and a second locking structure 27 detachably mounted on the upper end of the limit seat 5 and for locking the limit block 6. Limiting strips 28 matching the moving structure 24 are provided on both outer surfaces of the limit block 6, and the side surface of the limiting strip 28 away from the limit block 6 is an inclined surface.

[0050] The moving structure 24 includes a moving block 29 in contact with the limiting strip 28 and a moving strip 30 vertically fixed to one side surface of the moving block 29. Inclined surfaces matching the limiting strip 28 are provided on both outer surfaces of the moving block 29.

[0051] In the present invention, the first locking structure 25 includes a locking bar 31 arranged in a matching manner with the transmission structure 26 and a first locking block 32 detachably installed on one side of the locking bar 31 and used for locking the limiting block 6. First locking grooves into which the first locking block 32 is inserted are formed on both sides of the outer surface of the limiting block 6, and the vertical cross-sectional dimension of the first locking groove is larger than the vertical cross-sectional dimension of the first locking block 32.

[0052] In the present invention, the transmission structure 26 includes a transmission gear 33 respectively arranged on the upper and lower sides of the moving bar 30 and transmission racks 34 respectively arranged on the moving bar 30 and the locking bar 31. The transmission gear 33 is rotatably installed in the limiting seat 5. Second grooves matching with the transmission racks 34 are formed on both the moving bar 30 and the locking bar 31. One side of the transmission gear 33 is arranged in the second groove, and the height of the transmission rack 34 is less than the height of the second groove.

[0053] Guide grooves are formed on both the moving bar 30 and the locking bar 31. A plurality of groups of guide rods 57 matching with the guide grooves are detachably installed on the limiting seat 5, and the plurality of groups of guide rods 57 can respectively guide and support the moving bar 30 and the locking bar 31.

[0054] In the present invention, the second locking structure 27 includes a third driving structure 35 detachably installed at the upper end of the limiting seat 5 and a second locking block 36 movably arranged in the limiting seat 5 and detachably fixed to the output shaft of the third driving structure 35. A second locking groove aligned with the second locking block 36 is formed on the upper end surface of the limiting block 6, and the cross-sectional dimension of the second locking groove is larger than the cross-sectional dimension of the second locking block 36. A plurality of groups of moving grooves respectively fitting with the moving structure 24, the first locking structure 25, the transmission structure 26 and the second locking structure 27 are formed in the limiting seat 5.

[0055] In summary, after the threaded steel bar breaks during the tensile test, due to inertia, the second clamping seat 8 continues to move under the action of the second driving structure 13. The movement of the second clamping seat 8 drives the limiting block 6 to move, inserts the limiting block 6 into the limiting groove 23 on the limiting seat 5, enables the first protection block 21 and the second protection block 22 to perform buffer protection, and enables the two groups of third protection blocks 56 to perform buffer protection, thereby reducing the collision force between the second clamping seat 8 and the protection seat 4;

[0056] When the limiting strip 28 on the limiting block 6 contacts the moving block 29, the moving block 29 drives the moving bar 30 to move outwards. The movement of the moving bar 30 drives the transmission rack 34 to move. The transmission rack 34 drives the transmission rack 34 on the locking bar 31 to move through two groups of transmission gears 33 respectively. Thus, the locking bar 31 drives the first locking block 32 to insert into the first locking groove on the limiting block 6, locking and limiting the two sides of the limiting block 6. At the same time, the third driving structure 35 is started to drive the second locking block 36 to move downwards, inserting the second locking block 36 into the second locking groove at the upper end of the limiting block 6 to lock and limit the limiting block 6, thereby locking and limiting the second clamping seat 8, avoiding the second clamping seat 8 from rebounding under the action of force, and effectively protecting the second driving structure 13.

A protective pad 40 is detachably installed on the side surface of the protective cover 37 close to the second clamping seat 8.

[0062] In the present invention, the buffer structure 43 includes a buffer seat 44 movably arranged in the protection groove and connected to the protection rod 42, and a buffer member 45 sleeved on the protection rod 42 and aligned with the buffer seat 44. The buffer seat 44 has a "U" - shaped structure, and several groups of buffer blocks 46 for buffer connection with the buffer member 45 are symmetrically arranged on the buffer seat 44. Buffer grooves 47 for the buffer blocks 46 to move are formed on the buffer seat 44.

[0063] In the present invention, the protection component further includes a piston rod structure 48 vertically connected to the buffer seat 44 and a protection cavity 49 arranged in the buffer seat 44 and fittingly connected to the piston rod structure 48. Two buffer gaskets 50 are arranged in the buffer grooves 47. The buffer seat 44 is installed inside the detection seat 1 by bolts. The buffer seat 44 is made of a heat - dissipating material, and a heat - dissipating structure for dissipating heat from the buffer seat 44 is detachably installed inside the buffer seat 44. The heat - dissipating structure and the buffer seat 44 cooperate to dissipate heat from the buffer liquid. The two buffer gaskets 50 are respectively connected to the buffer blocks 46 and the inner wall of the buffer grooves 47. Through holes matching the piston rod structure 48 are formed on the buffer gaskets 50, so that the buffer gaskets 50 are sleeved on the piston rod structure 48 for protection. A buffer cavity 51 communicating with several groups of protection cavities 49 is arranged inside the buffer seat 44. Buffer liquid is stored in both the buffer cavity 51 and the protection cavity 49. A buffer spring 52 connected to the buffer member 45 is installed on the inner side of the buffer seat 44. The buffer spring 52 can buffer the buffer member 45 and the protection block 41, preventing the buffer member 45 from contacting the buffer seat 44 and damaging the buffer seat 44.

[0064] In the present invention, the protection component includes a protection block 53 vertically installed on the lower end face of the second clamping seat 8, a protection groove symmetrically formed on the upper end of the detection seat 1 and used for the protection block 53 to move horizontally, and a protection rod 54 vertically installed in the protection groove. The protection block 53 is movably sleeved on the protection rod 54, and a protection spring 55 connected to the protection groove is sleeved on the protection rod 54. One end of the protection spring 55 does not contact the protection block 53. After the steel bar breaks, the second clamping seat 8 drives the protection block 53 to move a certain distance until it contacts the protection spring 55.

[0065] In summary, after placing the steel bar between the two sets of protective covers 37 and clamping and fixing it, rotate the protective plate 38 so that the two sets of protective covers 37 are fixedly connected, and the protective covers 37 and the protective plate 38 cooperate with the protective plate 38. When the second driving structure 13 is started, it drives the connecting ring 39 to move, and drives the protective cover 37 to move through the connecting rod 20. The movement of the protective cover 37 drives the buffer protection block 41 to move in a guiding manner on the protective rod 42. When the steel bar breaks, the buffer protection block 41 moves forward rapidly and contacts the buffer member 45 to drive the buffer member 45 to move on the protective rod 42, so that the buffer member 45 squeezes and collides with the buffer block 46 during the movement, causing the buffer block 46 to move in the buffer groove 47, causing the buffer block 46 to drive the piston rod structure 48 to move in the protection cavity 49, so that the piston rod structure 48 squeezes the buffer liquid in the protection cavity 49 into the buffer cavity 51, so that the two buffer gaskets 50 buffer and protect the buffer block 46, and the buffer spring 52 on the protective rod 42 buffers and protects the buffer member 45; when the second driving structure 13 controls the second clamping seat 8 to move, the second clamping seat 8 drives the protection block 53 to move on the protection rod 54, so that the protection block 53 squeezes and buffers the protection spring 55 to consume the collision force.

[0066] Embodiment 4

[0067] Refer to Figure 1 - Figure 11 , this embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0068] The first clamping seat 7, the second clamping seat 8 and the clamping structure 9 cooperate to clamp and fix the steel bar. The second driving structure 13, the pressure sensor 14 and the detection block 2 cooperate to control the movement of the second clamping seat 8, and cooperate with the detection pointer 15, the detection scale 16, the signal receiving block 17 and the laser rangefinder 18 to perform tensile testing on the steel bar, and can improve the accuracy of the steel bar tensile testing. The first protection block 21, the second protection block 22 and the third protection block 56 cooperate to protect the second clamping seat 8 and the detection block 2, thereby reducing the collision force between the second clamping seat 8 and the protection seat 4. The moving structure 24, the first locking structure 25, the transmission structure 26 and the second locking structure 27 cooperate to lock and limit the limit block 6, thereby locking and limiting the second clamping seat 8, preventing the second clamping seat 8 from rebounding under the action of force, effectively protecting the second driving structure 13, and extending the service life of the detection structure 3;

[0069] The protective cover 37 and the protective plate 38 cooperate to prevent the flying metal fragments caused by the fracture of the steel bar from injuring the second driving structure 13 and the nearby workers. The connecting ring 39 and the connecting rod 20 enable the buffer protection block 41, the protection rod 42, the buffer structure 43, the buffer block 46, the piston rod structure 48, the protection cavity 49, the buffer gasket 50, the buffer cavity 51 and the buffer spring 52 to cooperate to effectively protect the second driving structure 13. The protection block 53, the protection rod 54 and the protection spring 55 effectively protect the second clamping seat 8, extending the service life.
