Description

Technical Field

[0001] The utility model belongs to the technical field of road and bridge engineering, and particularly relates to a steel bar detection device for road and bridge construction. Background Art

[0002] Rebar refers to steel used in reinforced concrete and prestressed concrete. Its cross-section is round, or sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. It is a commonly used material in construction projects. It is a long, iron-based material, typically used to support the skeleton and strengthen a building. In concrete structures, rebar is combined with concrete to form a reinforced concrete structure, thereby enhancing the building's strength and durability.

[0003] Rebar strength refers to the maximum stress a steel bar can withstand under external forces. Rebar strength is typically expressed in terms of tensile strength or yield strength. Tensile strength is the maximum stress a bar can withstand before breaking, while yield strength is the maximum stress a bar can withstand at the onset of plastic deformation. Rebar strength is a key indicator of rebar quality, directly impacting its effectiveness and safety in engineering structures.

[0004] When testing the strength of steel bars, pressure is usually applied to the bars, and the strength of the bars is determined by the change in the pressure value. The currently used testing agencies are not convenient for changing the position of the steel bars during the testing process. When testing, most of the same surface is tested, which easily leads to a single test result and the occurrence of errors. Utility Model Content

Transmission wheels 46 are respectively disposed on the surfaces of the first rotating shaft 43 and the output shaft of the first driving motor 45. The two transmission wheels 46 are connected by a transmission belt 47. By controlling the operation of the first driving motor 45, the transmission wheel 46 and the transmission belt 47 can be used to cause the first rotating shaft 43 to rotate.

[0027] The supporting mechanism 5 includes two second fixing rods 51 fixedly arranged on the upper surface of the U-shaped platform 1. The opposite surfaces of the first bearing block 21 and the two second fixing rods 51 are respectively inlaid with second bearings 52. Two second rotating shafts 53 are respectively arranged in the four second bearings 52. The surfaces of the two second rotating shafts 53 are respectively provided with second elastic sleeves 54. A first elastic sleeve 44 and two second elastic sleeves 54 are arranged in a triangle on the surface of the steel bar. The elastic sleeve is made of rubber. Through the elastic properties of the elastic sleeve, the steel bar can be squeezed by the action of the triangular elastic sleeve, and the steel bar can be rotated when the first elastic sleeve 44 above rotates.

[0028] Specifically, the lower surface of the first connecting plate 33 is fixedly connected to a first sliding rod 36, and the first sliding rod 36 slides in a first through hole 37 opened on the upper surface of the second connecting plate 34. The side surfaces of the second bearing block 31 are respectively provided with openings 38, and the length of the opening 38 is adapted to the side length of the pressing block 32, so as to facilitate clamping of the steel bars by the pressing block 32 and the second bearing block 31.

[0029] Specifically, a second through hole 6 and a threaded hole 7 are opened on the side of the second supporting block 31, and a second slide rod 8 is arranged in the second through hole 6. The arrangement of the second through hole 6 and the second slide rod 8 can make the movement of the second supporting block 31 more stable, and the two ends of the second slide rod 8 are fixedly connected to the surface of the U-shaped platform 1, and a threaded column 9 is threadedly connected in the threaded hole 7.

[0030] The working principle of this utility model is:

[0031] When in use, one end of the steel bar is passed through between the second bearing block 31 and the pressing block 32 and the two ends are placed on the surfaces of the first bearing block 21 and the second bearing block 31 respectively, and the working states of the first electric push rod 22, the second electric push rod 35, the first drive motor 45 and the second drive motor 10 are controlled respectively by the control system;

[0032] When the first electric push rod 22 is shortened, the fixing plate 23 can be moved downward, so that the pressure head 25 can be close to the steel bar to cut the steel bar. During the cutting process, the pressure sensor 24 senses the pressure. When the second electric push rod 35 is shortened, the pressure block 32 can be moved downward. The pressure block 32 and the second bearing block 31 can be used to clamp one end of the steel bar.

[0033] When the second drive motor 10 is working, it can drive the threaded column 9 to rotate, and can prompt the second bearing block 31 to drive the steel bar to move, so as to facilitate the use of the pressure head 25 to detect multiple parts of the steel bar. When the first drive motor 45 is working, the output shaft of the first drive motor 45 drives the first rotating shaft 43 to rotate through the transmission wheel 46 and the transmission belt 47. The first elastic sleeve 44 provided on the surface of the first rotating shaft 43 cooperates with the two second elastic sleeves 54 to promote the rotation of the steel bar (at this time, the pressure block 32 and the steel bar are in a separated state). After the steel bar rotates, it is convenient to detect multiple directions of the steel bar.
