A testing device for building materials

Abstract

The invention relates to the technical field of detection equipment, and discloses a detection equipment for building materials. The invention solves the problem that as the number of equipment detections increases and accumulates, steel bars damage clamping and fixing components at both ends, thereby causing them to loosen and affect detection accuracy. A driving mechanism drives arcuate rack 1 and arcuate rack 2 to rotate in opposite directions, and at the same time applies pressure to both ends of a steel bar body, causing the middle part of the steel bar body to bend. The pressure change during the entire bending process is recorded by a detection component. During the bending process, clamping components 1 and 2 change their own angles according to the curvature of cavity rings 1 and 2, thereby reducing the impact on structural strength and expanding the range of detection angles. Clamping components 1 and 2 adaptively clamp steel bar bodies of different diameters, thereby avoiding the steel bar body from being offset during the bending process, which affects the detection result.

Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, in particular to a detection equipment for building materials. Background Art

[0002] In modern construction projects, steel bars, as a key structural material, play an important role in bearing and reinforcing the main structure of the building. The quality of steel bars is directly related to the safety, durability and stability of the entire building. Therefore, manufacturers will conduct random inspections on each batch of steel bars produced, and compare the test data with the original qualified data to determine whether the quality of this batch of steel bars meets the qualified requirements.

[0003] For example, a Chinese patent with the existing publication number CN222013760U discloses a steel bar strength testing device. First, the steel bar is passed through the lower clamp block and placed on the inner wall surface of the lower clamp block. Then, the rotating rod is twisted to make the rotating rod drive the threaded block to rotate. The threaded block drives the rotating rod and the upper clamp block to descend to clamp the two ends of the steel bar. Then, the hydraulic rod is started to drive the hydraulic rod to rise to bend the steel bar to a certain angle or radius. Then, it is observed whether cracks or deformation occur to detect the flexibility and cold bending of the steel bar.

[0004] The following problems will occur during the use of this detection equipment: on the one hand, the middle part of the steel bar will generate huge tensile force on both ends and an upward bending force on the upper clamp during the bending process. As the number of equipment detections increases and accumulates, it will cause irreversible damage to the equipment, and the accuracy of its detection values ​​will also decrease. In order to ensure the accuracy of the detection values, it is necessary to replace it frequently, which greatly increases the cost of use. In addition, due to the existence of tensile force, the steel bar cannot be bent at a large angle, which leads to a very limited detection range and poor practicality.

[0005] Therefore, a kind of testing equipment of building materials is needed. Summary of the invention

The two sets of gears are respectively meshed with arc gear track 1 and arc gear track 2. The gears are rotated by starting the servo motor to drive the rotating shaft. Since the bevel gear is meshing with the gears, the two sets of transmission members are driven to rotate counterclockwise as a whole.

[0011] Furthermore, two sets of sliding grooves are provided on the outer surface of the arc frame, and a slider is fixedly installed at one end of arc rack one and arc rack two, and the slider is slidably connected to the sliding groove. When arc rack one and arc rack two rotate, they simultaneously drive the slider to slide in the sliding groove, thereby effectively improving its stability during rotation and improving its structural strength.

[0012] Furthermore, four groups of guide grooves are provided inside the arc frame, and the four groups of guide grooves are respectively slidably connected to the two groups of sliding members one and the two groups of sliding members two. The arc gear rail one and the arc gear rail two pass through the guide grooves. Through the opening of the guide grooves, the clamping and bending components one and the clamping and bending components two can rotate more smoothly and steadily, which facilitates the precise control of the bending angle.

[0013] Furthermore, the driven member 1 includes an adjusting plate and a telescopic rod located on one side of the adjusting plate and both ends of the telescopic rod are fixedly connected, one end of the telescopic rod away from the adjusting plate is fixedly connected to the sliding member 1, a spring is sleeved on the outer side of the telescopic rod, one end of the spring is fixedly connected to the adjusting plate, and the other end of the spring is fixedly connected to the sliding member 1, and the spring and the telescopic rod are compressed by pushing the adjusting plate, thereby driving the clamping member 1 to move horizontally as a whole, at this time, one end of the steel bar body can be placed inside the clamping member 2, and then the other end of the steel bar body is aligned with the clamping member 1, and then the push on the adjusting plate is released, and under the resetting of the spring, the other end of the steel bar body enters into the interior of the clamping member 1, thereby realizing the preliminary positioning of the steel bar body.

In the process of entering the slot, the clamping block 1 will squeeze the clamping block 2 and compress the clamping spring until the clamping block 1 is completely fitted with the slot. At this time, under the reset thrust of the clamping spring, the clamping block 2 and the clamping block 1 are completely engaged.

[0016] Furthermore, the detection component includes an L-plate fixedly connected to the arc-shaped frame and a pressure sensor located at the lower end of the L-plate and fixedly connected.

[0017] Furthermore, the cavity ring 1 is fixedly connected to the arc frame, and an arc groove is symmetrically provided inside the arc frame. The clamping member 1 includes a telescopic tube and an arc-shaped telescopic plate located at one end of the telescopic tube and fixedly connected. The telescopic tube is slidably connected to the arc groove, one end of the arc-shaped telescopic plate is fixedly connected to the cavity ring 1, and an extrusion plate is fixedly installed on the other end of the arc-shaped telescopic plate, and a sleeve is fixedly installed on the other end of the telescopic tube, and a guide block is fixedly installed on the inside of the sleeve, and an upper half cavity and a lower half cavity are provided inside the sleeve. The structures of the clamping member 1 and the clamping member 2 are exactly the same. During the overall rotation of the clamping member 1, the telescopic tube will compress the arc-shaped telescopic plate, and due to the setting of the guide block, the squeezed gas will enter the upper half cavity and the lower half cavity.

Since the driven plate and the driven spring are provided inside the lower half cavity, the gas enters the upper half cavity first, and when the gas in the upper half cavity is full, it enters the piston The inside of the tube pushes the piston rod to drive the three groups of clamping rings to descend and clamp the steel bar body less, and the excess gas will push the driven plate to compress the driven spring less to meet the space required by the gas. When the diameter of the steel bar body is small, it can be stably clamped by the rightmost clamping ring. When the diameter of the steel bar body is medium, it is stably clamped by the rightmost and middle clamping rings. Since the rightmost clamping ring has not moved to the maximum stroke, the excess gas will enter the lower half cavity and join in the compression of the driven spring. When the diameter of the steel bar body is large, it is stably clamped by the three groups of clamping rings at the same time. Since the rightmost and middle clamping rings have not moved to the maximum stroke, the excess gas will enter the lower half cavity and join in the compression of the driven spring, thereby realizing adaptive clamping of steel bars of different diameters, effectively avoiding the displacement of the steel bar body during the bending process, which affects the detection results.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The invention provides a testing device for building materials. First, two ends of a steel bar body are respectively inserted into a clamping member 1 and a clamping member 2. Then, a driving mechanism is used to drive an arc gear track 1 to rotate in a clockwise direction, and at the same time, the arc gear track 2 is driven to rotate in a counterclockwise direction. Thus, the clamping member 1 and the clamping member 2 simultaneously apply upward pressure to the two ends of the steel bar body, so that the middle part of the steel bar body is bent and a certain pressure is generated on the testing member. The pressure change during the entire bending process is fully recorded by the testing member.

A certain pressure is generated on the detection piece 3, and the pressure change in the whole bending process is recorded by the detection piece 3. The personnel judge whether it is qualified by comparing the curve change of the pressure value with the original qualified curve change of the pressure value.

The stroke of the driven telescopic rod 4582 at the upper end of the middle clamping ring 458 is shorter than that of the driven telescopic rod 4582 at the upper end of the rightmost clamping ring 458. Since the driven plate 4552 and the driven spring 4551 are arranged inside the lower half cavity 455, the gas enters the upper half cavity 455 first. In the cavity 459, after the gas in the upper cavity 459 is full, it will enter the interior of the piston tube 457 and push the piston rod 4581 to drive the three groups of clamping rings 458 to descend to clamp the steel bar body 6, and the excess gas will push the driven plate 4552 to compress the driven spring 4551 slightly to meet the space required by the gas. When the diameter of the steel bar body 6 is small, it can be stably clamped by the rightmost clamping ring 458. When the diameter of the steel bar body 6 is medium, it can be stably clamped by the rightmost and middle clamping rings 458. 8 does not move to the maximum stroke, excess gas will enter the lower cavity 455 and join in the compression of the driven spring 4551. When the diameter of the steel bar body 6 is large, it is stably clamped by three groups of clamping rings 458 at the same time. Since the clamping rings 458 on the far right and in the middle do not move to the maximum stroke, excess gas will enter the lower cavity 455 and join in the compression of the driven spring 4551, thereby realizing adaptive clamping of steel bar bodies 6 of different diameters, and effectively avoiding the displacement of the steel bar body 6 during the bending process, which affects the detection result.
