Description

Technical Field

[0001] The present application relates to the technical field of engineering building material testing devices, and specifically to a building material strength testing device for engineering supervision. Background Art

[0002] A large number of steel plates are usually used in construction sites and other places. The strength of construction steel refers to the ability of the material to resist fracture under external forces. The strength of construction steel is an important indicator that must be measured during the use of the material. When these steel plates enter the construction site, the project supervisor will randomly sample them for bending resistance testing.

[0003] However, when the existing steel plate bending strength testing machine is testing the bending strength of the steel plate, the test data of the steel plate strength is affected by many factors. When testing the steel plate, the project supervisor needs to hold the steel plate and place it on the testing table. However, it is impossible to ensure whether there is an angle deviation of the steel plate. When the steel plate is placed at an uneven angle, the loading force will be unevenly distributed on the steel plate, resulting in local stress concentration. This stress concentration phenomenon will cause the steel plate to be damaged under a relatively low external force, thereby underestimating the bending strength of the steel plate.

[0004] Therefore, the present application provides a building material strength detection device for engineering supervision to solve the above problems. Utility Model Content

[0005] The present application provides a building material strength testing device for engineering supervision, which aims to solve the problem in the background technology that when the existing steel plates are placed at uneven angles, the loading force will be unevenly distributed on the steel plates, resulting in inaccurate test results.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a building material strength detection device for engineering supervision, comprising a frame installed on the upper end of a processing table and a bending assembly arranged on the frame, a material loading seat is symmetrically arranged on the inner side of the frame, and a loading mechanism is arranged on the front of the processing table;

[0007] The feeding mechanism comprises a baffle plate movably sleeved on the positioning shaft and a support plate installed on the front of the baffle plate, the positioning shaft is fixedly installed on the processing table, the back of the baffle plate is movably connected with a bidirectional screw rod, and the center of the bidirectional screw rod is sleeved with an inclined gear, and the outside of the bidirectional screw rod is symmetrically sleeved with a correction component;

[0008] Among them, a servo motor is installed on the back of the material baffle plate, and a main gear is installed on the output end of the servo motor, and the main gear is meshed with the inclined gear. The main gear on the output end of the servo motor meshes with the inclined gear at the center of the bidirectional screw rod. The output end of the servo motor rotates forward, driving the bidirectional screw rod with symmetrically distributed sliders to clamp the steel plate on the support plate at the same time. The output end of the servo motor rotates in the opposite direction, and the two sets of sliders are away from the steel plate.

[0009] Preferably, the correction component includes a limiting slide groove symmetrically opened on the back of the material baffle plate and a slider slidably installed on the limiting slide groove, the slider is threadedly sleeved with the bidirectional screw rod, a fixing rod is installed at the tail end of the slider, and a correction arm is installed at the tail end of the fixing rod. The limiting slide groove opened on the back of the material baffle plate is mainly used for limiting the sliding of the slider to prevent the slider from rotating during the rotation of the bidirectional screw rod, and the fixing rod installed at the tail end of the slider serves to connect the correction arm and move synchronously with the slider.

[0010] Preferably, a correction plate is installed on the upper end of the support plate, and the correction plate is in the shape of a rectangular strip. The correction plate is installed on the upper end of the support plate. When the steel plate is placed on the upper end of the support plate, as long as one side is in contact with the correction plate, there will be no angle deviation.

[0011] Preferably, a material discharge port is provided at the upper end of the processing table, and the material discharge port is located between the two loading seats.

[0012] Preferably, a cone block is installed inside the processing table, and a material collection box and a building material strength detection device for engineering supervision are installed on the front of the processing table.

[0013] The detection device uses a feeding mechanism set on the front side of the processing table, and the upper end of the material blocking plate is movably sleeved with the positioning shaft on the processing table. When loading the steel plate, the steel plate is placed in the front position of the support plate, and one side of the steel plate is against the correction plate. The correction plate keeps the steel plate corrected to avoid angle deviation, and then the fixed rods at both ends are driven by a servo motor to approach both sides of the steel plate at the same time until it is clamped. At this time, the steel plate is in the center position, and the material blocking plate is manually turned over by the positioning shaft until the top surface of the steel plate overlaps the roller of the loading seat. The correction arm no longer clamps the steel plate, and the material blocking plate can be pushed back to its original position, thereby realizing the correction of the steel plate during feeding and improving the accuracy of the detection results.

[0014] The detection device is provided with a material baffle plate on the front of the processing table. When the steel plate detection is completed, the symmetrically distributed loading seats will shrink outward. At this time, the steel plate samples in a bent state will fall from the discharge port to the upper end of the cone block, and slide toward the material baffle plate along the inclined angle of the cone block. The back of the material baffle plate will block the steel plate samples to prevent the steel plate samples from being discharged too quickly and causing scratches to the staff.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] This embodiment provides a building material strength detection device for engineering supervision, such as Figure 1-5 As shown, the detection device includes a frame 1 installed on the upper end of a processing table 4 and a bending assembly 2 arranged on the frame 1, a material carrier 3 is symmetrically arranged on the inner side of the frame 1, and a loading mechanism 5 is arranged on the front of the processing table 4;

[0032] The feeding mechanism 5 includes a baffle plate 51 movably mounted on the positioning shaft 7 and a support plate 52 mounted on the front of the baffle plate 51. The positioning shaft 7 is fixedly mounted on the processing table 4. A bidirectional screw rod 56 is movably connected to the back of the baffle plate 51, and a tilting gear is mounted at the center of the bidirectional screw rod 56. A correction component is symmetrically mounted on the outside of the bidirectional screw rod 56.

[0033] A servo motor 55 is installed at the back of the baffle plate 51 , and a main gear is installed at the output end of the servo motor 55 , and the main gear is meshed and connected with the inclined gear.

[0034] Specifically, the positioning shaft 7 is installed at the recess on the front side of the processing table 4, and the upper end of the material baffle plate 51 is movably mounted on the positioning shaft 7, so that the material baffle plate 51 can be turned over at any time. The bidirectional screw rod 56 is installed on the back of the material baffle plate 51 by four groups of assembly plates, and the base of the servo motor 55 is installed on the back of the material baffle plate 51 by bolts. The main gear on the output end of the servo motor 55 is meshed with the inclined gear at the center of the bidirectional screw rod 56. The output end of the servo motor 55 rotates forward, driving the bidirectional screw rod 56 with the symmetrically distributed sliders 58 to clamp the steel plate on the support plate 52 at the same time, and the output end of the servo motor 55 rotates in the opposite direction, and the two groups of sliders 58 are away from the steel plate.

[0035] The correction component includes a limiting slide groove 57 symmetrically opened on the back of the baffle plate 51 and a slider 58 slidably installed on the limiting slide groove 57. The slider 58 is threadedly sleeved with the bidirectional screw rod 56. A fixing rod 54 is installed at the tail end of the slider 58, and a correction arm 53 is installed at the tail end of the fixing rod 54.

[0036] More specifically, the limiting groove 57 provided on the back of the baffle plate 51 is mainly used for limiting the sliding of the slider 58 to prevent the slider 58 from rotating during the rotation of the bidirectional screw 56. The fixed rod 54 installed at the tail end of the slider 58 connects the correction arm 53 and moves synchronously with the slider 58, so as to realize the clamping action. Since the bidirectional screw 56 is a bidirectional thread, when the two sets of sliders 58 are in the most forward position during installation, the two sets of correction arms 53 move synchronously. Therefore, when the two sets of correction arms 53 are close to each other, the steel plate will be in the center position.

[0037] A correction plate 59 is installed on the upper end of the support plate 52, and the correction plate 59 is in a rectangular strip shape.

[0038] It should be noted that the correction plate 59 is installed on the upper end of the support plate 52. When the steel plate is placed on the upper end of the support plate 52, as long as one side is in contact with the correction plate 59, it is guaranteed that there will be no angle deviation.

[0039] A material discharge port 42 is provided at the upper end of the processing table 4 , and the material discharge port 42 is located between the two material loading seats 3 . A cone block 41 is installed inside the processing table 4 , and a material collecting box 6 is installed on the front of the processing table 4 .

[0040] It is worth mentioning that the unloading port 42 opened at the upper end of the processing table 4 is used for the steel plate that has passed the bending strength test to fall onto the cone block 41 after the loading seat 3 is withdrawn, without the need to manually remove the steel plate, thus avoiding safety accidents caused by operational errors during unloading.

[0041] When in use, a feeding mechanism 5 is set on the front side of the processing table 4, and the upper end of the material blocking plate 51 is movably sleeved with the positioning shaft 7 on the processing table 4. When loading the steel plate, the steel plate is placed in the front position of the support plate 52, and one side of the steel plate is against the correction plate 59, and the steel plate is kept corrected by the correction plate 59, and then the servo motor 55 drives the fixing rods 54 at both ends to approach the two sides of the steel plate at the same time until it is clamped. At this time, the steel plate is in the center position, and the positioning shaft 7 is used to manually turn the material blocking plate 51 until the top surface of the steel plate overlaps the roller of the loading seat 3, and the correction arm 53 no longer clamps the steel plate, and the material blocking plate can be removed. The plate 51 is pushed back to its original position to achieve correction when the steel plate is loaded. After the press-bending component 2 performs stamping and bending inspection on the steel plate, the two sets of loading seats 3 are recovered, and the bent steel plate falls from the unloading port 42 to the upper end of the cone block 41 and is blocked by the back of the baffle plate 51. When the baffle plate 51 is used to place a new steel plate, the baffle plate 51 is flipped and no longer blocks the steel plate on the cone block 41. At this time, the steel plate that has passed the bending inspection slides from the cone block 41 to the inside of the collecting box 6, completing the unloading operation. The baffle plate 51 can not only complete the loading operation, but also perform unloading buffering operation on the steel plate that has passed the inspection.

[0042] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
