Description

Technical Field

[0001] The invention relates to a bending resistance testing device, in particular to a bending resistance testing device for steel bars used in water conservancy construction, and belongs to the technical field of steel bar testing. Background Art

[0002] Steel bars are one of the main building materials in water conservancy projects. In water conservancy projects, especially large concrete structures such as dams, channels, sluice gates, etc., sufficient strength is required to withstand water pressure, soil pressure and various loads. The addition of steel bars can greatly improve the tensile and compressive strength of concrete, ensuring the stability and durability of the engineering structure; the steel bar bending resistance test is an important quality control measure in the construction of water conservancy projects, because water conservancy projects usually involve a large number of concrete structures, and these structures will be subjected to various forces during construction and use, including bending forces; if the steel bar's bending resistance is insufficient, it will cause cracks, damage or even collapse of the concrete structure during construction or use, thus affecting the safety and durability of the project.

[0003] Patent document CN116625846B discloses a bending performance testing device for building steel bars, which can perform bending tests on steel bars of different lengths, making the testing function more abundant, and can apply testing forces in different directions to the steel bars, so that the steel bars can be bent in different directions, thereby testing the bending resistance of the steel bars in different directions. However, the overall structure of the device is too large, and it is not convenient for mobile operations. In addition, when performing the test, the steel bars need to be inserted into the device, and the test operation method is too cumbersome.

[0004] Patent document CN210788730U discloses a portable bending machine for construction site construction. Although the bending machine has a compact structure, is easy to carry, takes up little space when in use, and is relatively labor-saving, it can bend steel quickly and efficiently. However, it does not have a detection function and cannot detect the bending resistance of steel bars. Moreover, its bending is mainly to push the steel outward using an arc-shaped bending plate and limit the position using two steel wheels to achieve the bending operation. Affected by the bending direction, the two ends of the bent steel will move toward the direction of the hydraulic jack at the same time. During the bending process, the staff needs to use an operating rod to operate the hydraulic jack, which poses a safety hazard. Moreover, during the bending operation, the steel needs to be placed on the swing arm first, and the operation is still inconvenient, especially when facing some large-diameter and heavy-weight steel bars. The operation is even more inconvenient. Therefore, a steel bar bending resistance detection device and a method for use for water conservancy construction are proposed. Summary of the invention

[0075] In one embodiment, the auxiliary support mechanism 6 includes an auxiliary support arm 601, two second rollers 602, a connecting block 603 and two torsion springs 604;

The connecting block 603 is then used to limit the rotated auxiliary support arm 601. The sleeve frame 101 is then tilted and its gravity is used so that the auxiliary support arm 601 can stand between the sleeve frame 101 and the ground to provide support for the sleeve frame 101.

[0078] In one embodiment, a handle 71 is fixedly connected to one end of the sleeve frame 101, and a connecting sleeve 72 is threadedly connected to the outer walls of the first traction arm 301 and the second traction arm 302. The inner wall of the sleeve frame 101 is fixedly connected to two inner support rings 73, and the hydraulic cylinder 103 is installed between the two inner support rings 73. The outer walls of a plurality of connecting rods 306 are slidably connected to the inner walls of the inner support rings 73.

[0079] The handle 71 is provided so that the sleeve frame 101 can be driven to move as a whole by holding the handle 71. The connecting sleeve 72 is provided to connect the first traction arm 301 and the second traction arm 302. The inner support ring 73 is provided to install and fix the hydraulic cylinder 103 inside the sleeve frame 101.

[0080] When the present invention is in operation: the entire device is moved to a specified position by moving the handle 71, the first roller 304 cooperates with the first traction arm 301 to lift the entire device off the ground during the movement, and the friction between the device and the ground is reduced by rolling, making the entire device easier to move.

[0081] When the equipment moves to the specified position, the two worm gear parts 202 are driven to rotate by rotating the annular knob 204 and the hollow worm gear 205. The two rotating worm gear parts 202 drive the support wheel 203 to move by the side support arm 201, so as to adjust the distance between the two support wheels 203 according to actual detection requirements, and the worm gear part 202 can be used in conjunction with the hollow worm gear 205 to prevent the side support arm 201 and the support wheel 203 from moving during the anti-bending detection process.

[0082] When the distance adjustment of the support wheel 203 is completed, the threaded column 502 is driven to rotate by rotating the torsion knob 501, and the rotating threaded column 502 drives the threaded sleeve 503 to move by the thread, and the moving threaded sleeve 503 drives the limit plate 504 to slide inside the sleeve frame 101, so that the limit plate 504 can be used to adjust the movable range of the inner support plate 303 in the sleeve frame 101.

[0083] When it is necessary to inspect the steel bars, first, the manual hydraulic pump 102 is pressed to provide power for the hydraulic cylinder 103, and then the piston rod of the hydraulic cylinder 103 uses the inner support plate 303 and the connecting rod 306 to drive the second traction arm 302 to slide out from the inside of the sleeve frame 101, and the first traction arm 301 is used to drive the first roller 304 and the traction wheel 305 to move through the second traction arm 302, so that the traction wheel 305 is located on the side of the two support wheels 203 away from the sleeve frame 101, and space for accommodating the steel bars is reserved between the traction wheel 305 and the two support wheels 203. When the position adjustment of the traction wheel 305 is completed, the connecting sleeve 72 is rotated to slide to one side of the first traction arm 301 through the thread to release the limit of the first traction arm 301 and the second traction arm 302, so that the first roller 304 can drive the first traction arm 301 to move when it contacts the ground, and prevent the first traction arm 301 and the first roller 304 from interfering with the subsequent actions. Then the mobile device drives the two support wheels 203 to fit with one side of the steel bar, and uses the steel bar as the axis to make the axis of the first traction arm 301 coincide with the axis of the second traction arm 302 again by tilting the sleeve frame 101, so that the traction wheel 305, the steel bar and the two support wheels 203 are located at the same level. On the plane, the manual hydraulic pump 102 is then pressed to drive the hydraulic cylinder 103 to drive the inner support plate 303 to move in the opposite direction. The inner support plate 303 moving in the opposite direction uses the second traction arm 302 to drive the first traction arm 301 to move. The moving first traction arm 301 drives the traction wheel 305 to squeeze the side of the steel bar away from the support wheel 203; then the pressure between the hydraulic cylinder 103 and the inner support plate 303 is detected by the pressure sensor 404, and the data detected by the pressure sensor 404 is received by the control module 402, and then the data received by the control module 402 is displayed on the display screen 403 to visualize the data so as to determine the current steel bar bending resistance through the pressure data.

[0084] When the data detected by the pressure sensor 404 reaches the bending resistance and pressure bearing standard of the steel bar of this specification, the manual hydraulic pump 102 is used to control the hydraulic cylinder 103 to drive the inner support plate 303 to move, so that the traction wheel 305 is separated from the steel bar, so that the steel bar can be removed from between the traction wheel 305 and the support wheel 203, so as to continue to detect the remaining steel bars.

[0085] When the data detected by the pressure sensor 404 does not meet the bending resistance and pressure bearing standard of the steel bar of this specification, and bending occurs under the action of pressure, the steel bar is bent in the opposite direction of the sleeve frame 101 by utilizing the traction wheel 305 in cooperation with the two support wheels 203, and the moving inner support plate 303 is limited by the limit plate 504 to control the bending amplitude to prevent the bending amplitude from causing a safety accident. Then, the manual hydraulic pump 102 controls the hydraulic cylinder 103 to drive the inner support plate 303 to move, so that the traction wheel 305 is separated from the bent steel bar, so that the bent steel bar can be removed from between the traction wheel 305 and the support wheel 203.

[0086] When the sleeve frame 101 needs to be supported as a whole during the detection process, the auxiliary support arm 601 is moved to rotate one end of the auxiliary support arm in the connection block 603, and the torsion spring 604 is driven to twist, and then the auxiliary support arm 601 after rotation is limited by the connection block 603, so as to control the rotation angle of the auxiliary support arm 601, and then the weight of the sleeve frame 101 as a whole is used to prevent the auxiliary support arm 601 from moving in the reverse direction due to the torsion force of the torsion spring 604 during the support process, so that the sleeve frame 101 can stand on the ground, and the auxiliary support arm 601 can still move with the sleeve frame 101 in the support state through the second roller 602. When the auxiliary support arm 601 needs to be stored, it is only necessary to move the sleeve frame 101 to drive the auxiliary support arm 601 and the second roller 602 to separate from the ground, and then the torsion spring 604 can drive the auxiliary support arm 601 and the second roller 602 to reset.
