[0002] On a construction site, quality inspection personnel need to cut the steel bars on site and take them back to the laboratory for steel bar strength detection. Steel bars are very important materials in the process of building houses. The strength of steel bars often determines the strength of the final house. In order to avoid the situation that the quality of steel bars does not meet the requirements, resulting in the situation that the quality of the house does not meet the requirements, or even the danger of house collapse, it is necessary to detect the compressive capacity of steel bars.

[0003] For example, a compressive strength detection device for building steel bars with the publication number of CN 208537305 U in the Chinese Patent Network can apply pressure to the steel bars vertically up and down, avoiding the phenomenon of uneven stress on the steel bars, improving the accuracy of the compressive detection of steel bars, and can stably fix the push rod motor, thus ensuring that the force-applying push rod transfers pressure to the pressure-applying plate more stably, ensuring the working stability of the device, and ensuring the stability when the pressure-applying plate moves up and down. However, in this patent, manual operations are required for loading and unloading the steel bars. When there are many steel bars for sampling and detection, it will also increase the labor of the staff, thus reducing the detection efficiency. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. 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.

[0018] Please refer to Figures 1-3 , a steel bar strength detection device for building engineering quality detection in this embodiment, includes a detection table 1 and a pressure detection device 7 installed on the detection table 1. There are four detection ends of the pressure detection device 7. A turntable 2 is installed at the center of the detection table 1, and two groups of vibrating feeding tables 5 and two loading and unloading devices 8 are distributed outside the turntable 2. The clamping ends of the loading and unloading devices 8 are one short and one long. Two feeding channels are formed on the vibrating feeding table 5, a jacking assembly 4 below the loading and unloading device 8 and the pressure detection device 7, and a feeding assembly 6 fixed below the loading and unloading device 8 at the feeding place and docked with the feeding channel of the vibrating feeding table 5. A plurality of bearing parts 3 are installed on the top of the turntable 2.

[0019] In the above structure, the steel bar can be conveyed to the feeding assembly through the vibrating conveying table, and then the steel bar can be transferred to a position perpendicular to the lower part of one of the loading and unloading devices through the feeding assembly. The steel bar can be transferred to the bearing part for placement through the loading and unloading device, and the turntable rotates to drive the steel bar to be transferred below the pressure detection device. At this time, the jacking assembly jacks up the bearing part, so as to support the bearing part and improve the stability during detection. After the detection is completed by the pressure detection device, when the detected steel bar is transferred to the lower part of the other loading and unloading device, at this time, the other group of jacking assemblies jacks up, so that the bearing part can be jacked up until the loading and unloading device clamps the steel bar, so as to complete the removal of the steel bar. Therefore, automatic loading and unloading can be realized to complete the detection of the steel bar, and the detection efficiency can be effectively improved.

[0020] Such as Figure 3For the shown direction, in order to achieve the operation of automatic feeding, the feeding assembly 6 includes two vertical plates 601 fixed on the detection table 1 and opposite to the two vibrating feeding tables 5. A frame plate 604 is fixed at the top of the vertical plate 601, and a guide plate 610 is attached to the frame plate 604. The guide plate 610 is L-shaped, and a rotating part is installed on the front. A roller 605 connected to the rotating part is rotatably arranged inside the frame plate 604. An arc adapted to the roller 605 is formed on one side of the guide plate 610 opposite to the roller 605, so that a side platform is formed at the hole of the guide plate 610. A bearing block 606 that can be docked with the hole on the guide plate 610 is embedded on the roller 605. The hole of the guide plate 610 is docked with the vibrating feeding table 5. Through the vibration of the vibrating feeding table, the sample steel bars will pass through the guide channel and enter the bearing block through the guide plate in sequence. One end of the steel bar will protrude into the hole of the side platform. Therefore, when the rotating part drives the roller to rotate, it can be unrestricted. Thus, the steel bar can be opposite to the loading and unloading device to complete the feeding operation.

[0021] Among them, in order to achieve feeding through the active roller, the rotating part includes a front push cylinder 602 fixed on the front of the vertical plate 601. A rack 603 slidably connected to the vertical plate 601 is fixed at the top end of the front push cylinder 602. A gear 607 meshing with the rack 603 is fixed at the right shaft end of the roller 605. When the steel bar enters the bearing block, the front push cylinder pushes the rack to drive the gear to rotate. Therefore, the roller will rotate simultaneously, so that the steel bar is perpendicular to the loading and unloading device to complete the feeding operation.

[0022] In addition, in order to achieve orderly feeding, an upper plate 608 located above the front push cylinder 602 is fixed on the front of the guide plate 610. A limit cylinder 609 is installed at the top of the left side of the upper plate 608. The two top ends of the limit cylinder 609 can extend into the hole of the guide plate 610. When the rotating part drives the roller to move the steel bar to be vertical, at this time, the limit cylinder drives the top end to insert into the hole of the guide plate, so as to block the subsequent conveyed steel bars and achieve the function of pre-waiting.

[0023] As Figure 2 For the shown direction, to drive the steel bar to jack up and support, the bearing part 3 includes a plurality of sleeve blocks 301 fixed on the turntable 2. A bearing plate 302 is slidably connected inside the sleeve block 301. Three bearing holes are opened at the top of the bearing plate 302. The bearing plate 302 is T-shaped, and the bottom end is a cube. A bottom block 303 is fixed at the bottom of the bearing plate 302. A sleeve column 304 extending to slide at the bottom of the turntable 2 is fixed on the bottom block 303. The steel bar is placed through the bearing plate. When the bearing plate is moved to below the pressure detection device, the jacking assembly jacks up, which will drive the bearing plate to jack up until the bottom block is in contact with the bottom of the turntable to form a support. Therefore, when the pressure detection device presses down, it can support the bearing part and the turntable to improve the stability of the downward pressure detection.

[0024] Among them, the jacking assembly 4 includes two backing plates 401 fixed on the inspection table 1. A propulsion cylinder 402 and a support sleeve plate 404 are installed on the backing plate 401. A push block 403 that slides with the backing plate 401 is fixed to the ejection end of the propulsion cylinder 402. A top block 405 that abuts against the push block 403 is slidably connected inside the support sleeve plate 404. The top block 405 is T-shaped. A slope that fits each other is formed on the top of the push block 403 and the bottom of the top block 405. By ejecting or retracting the push block with the propulsion cylinder, the top block can be jacked up by the slope on the push block cooperating with the slope of the top block, so that the bottom block can be jacked up by the top block. Therefore, the support of the bearing plate and the operation of facilitating material discharging can be completed. At the same time, the slope on the push block cooperating with the slope of the top block can reduce the load on the propulsion cylinder, thereby extending the service life.

[0025] The working principle of the above embodiment is as follows:

[0026] First, the vibrating feeding table transfers the sample steel bars in the guide channel by vibration until the steel bars pass through the guide plate and extend into the bearing block. Then, the front push cylinder drives the rack to move, and the roller is driven to rotate through the gear, so that the steel bars are perpendicular to the lower part of the loading and unloading device at the loading position. At the same time, the limiting cylinder pushes down to limit the steel bars during the conveying process, playing a role of pre-waiting, which can ensure the orderliness of the conveying. Then, the loading and unloading device grabs and transplants the steel bars into the placement holes of the bearing plate, and cooperates with the rotation of the turntable to drive the sample to wait under the pressure detection device. At this time, the propulsion cylinder drives the top block to jack up through the push block. Therefore, the bearing plate can be pushed up by the bottom block. Then, when the pressure detection device presses down for detection, it can play a supporting role, improving the detection stability. After the detection is completed, the jacking assembly returns to its original position. When the turntable moves the detected bearing part to the lower part of the loading and unloading device at the unloading position, the jacking assembly of the loading and unloading device at the unloading position jacks up the bearing part, facilitating the loading and unloading device to transplant the detected steel bars. In summary, automatic loading and unloading operations can be realized during the detection, thereby improving the detection efficiency.
