Description

Technical Field

[0001] The present invention relates to the technical field of lightweight wallboards, and specifically to a device for detecting the bearing capacity of lightweight wallboards. Background Art

[0002] Lightweight wallboards are a new type of energy-saving wall material. Due to their advantages such as light weight, convenient installation, energy conservation and environmental protection, they have been widely used in the construction industry. When installing such wallboards, one only needs to stand up the boards and assemble them after applying a small amount of caulking mortar to the male and female tenons. However, lightweight wallboards also have some inherent disadvantages, such as limited load-bearing capacity, easy cracking of the wall surface, poor sound insulation effect, and poor moisture-proof performance. These disadvantages make lightweight wallboards unable to meet the actual needs in some specific application scenarios, such as environments that need to bear large loads or require high sound insulation and moisture-proof performance. Therefore, it is particularly important to detect the bearing capacity of lightweight wallboards to ensure their safety and reliability in actual applications.

[0003] Bearing capacity detection is a key link to ensure the quality of lightweight wallboards. Through detection, quality problems that may exist in the wallboards, such as cracks and honeycombing, can be discovered in a timely manner, thus avoiding safety accidents in actual applications. Bearing capacity detection usually includes multiple aspects such as impact resistance testing and compressive testing to comprehensively evaluate the mechanical properties of lightweight wallboards. These tests not only help to understand the actual load-bearing capacity of the wallboards, but also provide a scientific basis for the design, production and application of the wallboards.

[0004] Although the existing devices for detecting the bearing capacity of lightweight wallboards can meet the detection requirements to a certain extent, there are still some deficiencies. For example, when the existing devices for detecting the bearing capacity of lightweight wallboards conduct static pressure testing, it is necessary to stand up the lightweight wallboards to simulate the normal wallboard load for static pressure testing. However, the area of a single lightweight wallboard is relatively large, and it is difficult for a single person to operate. More than two people are required to stand it up smoothly, resulting in an increase in the labor cost of the test. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for detecting the bearing capacity of lightweight wallboards to solve the problem that it is difficult to install and erect large wallboards during the test of the traditional device for detecting the bearing capacity of lightweight wallboards as mentioned in the above background.

[0006] To achieve the above object, the present invention provides the following technical solution: A bearing capacity detection device for lightweight wallboards, comprising a gantry. Inside the gantry, there are two lifting columns rotatably connected. The two lifting columns are respectively located on both sides inside the gantry. A lifting frame is drivingly connected to the lifting columns. A pressure plate is fixedly connected to the lower part of the lifting frame. A pressure sensor is arranged inside the pressure plate. A hydraulic cylinder is fixedly connected to the top of the gantry. The output end of the hydraulic cylinder is fixedly connected to the lifting frame. The bottom of the gantry is rotatably connected to a wallboard clamping mechanism through a first sliding sleeve seat. A wallboard conveyor belt is arranged on one side of the bottom of the gantry. The wallboard conveyor belt is at the same height as the wallboard clamping mechanism;

[0007] The wallboard clamping mechanism includes a first clamping block and a second clamping block, and the first clamping block and the second clamping block are rotatably connected;

[0008] The bottom end of the lifting column is fixedly connected with a first bevel gear. The first bevel gear meshes with a second bevel gear. The second bevel gear is fixedly connected with a first drive shaft through a keyway. A first clutch plate is slidably connected to the first drive shaft. The first clutch plate is drivingly connected to a second clutch plate. The second clutch plate is slidably connected to a second drive shaft. The second drive shaft is fixedly connected with a first toothed ring. The first toothed ring is connected to a second toothed ring through gear transmission. The first toothed ring is fixedly connected with a third drive shaft. The third drive shaft penetrates through the second toothed ring and the second clamping block, and the third drive shaft is fixedly connected with the first clamping block. The second toothed ring is fixedly connected with the second clamping block.

[0009] In one example, sliding sleeves are fixedly connected to both ends of the lifting frame. The lifting column penetrates through the sliding sleeves. A spiral groove is provided on the outer side of the lifting column. A spiral slider is machined on the inner wall of the sliding sleeve. The spiral slider is slidably connected with the spiral groove.

[0010] In one example, there is one first clamping block and two second clamping blocks. The two second clamping blocks are respectively located at both ends of the first clamping block. The first clamping block and the second clamping blocks are respectively located on both sides of a common rotating shaft.

[0011] In one example, rubber cushion blocks are fitted and connected to the inner sides of the first clamping block and the second clamping block through dovetail grooves. Anti-slip grooves are machined on the outer sides of the rubber cushion blocks.

[0012] In one example, a first sliding groove is provided on the outer side of the first drive shaft. The first clutch plate is slidably connected with the first sliding groove.

[0013] In one example, a second sliding groove is provided on the second drive shaft. The second clutch plate is slidably connected with the second sliding groove. A limiting stop piece is fixedly connected to one end of the second drive shaft. A first spring is sleeved on the second drive shaft. The first spring is located between the second clutch plate and the first toothed ring.

[0014] In one example, a first groove is fixedly connected to the first clutch disc, and a second convex block is fixedly connected to the second clutch disc. The first groove and the second convex block are mutually engaged, and the cross-sections of the first groove and the second convex block are both trapezoids with one side thick and the other side thin.

[0015] In one example, a vertical stop block is arranged at the rear side of two second clamping blocks in the wall panel clamping mechanism. The vertical stop block is fixedly connected to the gantry. A telescopic groove is formed in the vertical stop block. The telescopic groove penetrates through the vertical stop block, and a positioning pressing block penetrates through the telescopic groove. One end of the positioning pressing block protrudes outside the telescopic groove, and a first inclined sliding block is fixedly connected to the other end of the positioning pressing block. A sliding rod is slidably connected to the back surface of the vertical stop block through a second sliding sleeve seat.

A second spring is sleeved outside the sliding rod. The second spring is located between the second sliding sleeve seat and the second inclined sliding block. The other end of the sliding rod is fixedly connected to a rotating ring through a connecting rod. The rotating ring is rotatably connected to the first clutch disc.

The first gear ring is meshed with the first transmission gear, the first transmission gear is meshed with the second transmission gear, and the second transmission gear is meshed with the second gear ring.

[0017] In one example, when the positioning pressing block slides in the telescopic groove, the maximum sliding distance of the first clutch disc is greater than the length of the shortest side of the first groove and the second convex block, and less than the length of the widest side of the first groove and the second convex block.

[0019] A lightweight wall panel bearing capacity detection device proposed by the present invention, by setting a rotatable wall panel clamping mechanism, at the beginning, the wall panel clamping mechanism opens laterally, which is convenient for the placement of the lightweight wall panel. The lowering of the lifting frame is used to drive the wall panel clamping mechanism to clamp the lightweight wall panel. After clamping, the second stroke starts. The wall panel clamping mechanism drives the lightweight wall panel to rotate and stand up. When it stands up to the vertical position, the wall panel clamping mechanism disengages from the transmission engagement, so as to facilitate the bearing capacity test of the lightweight wall panel. Once the lightweight wall panel topples, the wall panel clamping mechanism will quickly resume clamping to straighten the lightweight wall panel. Thereby, not only the operation process is simplified, but also the clamping accuracy and stability are improved. At the same time, it can ensure that it remains stable during the test process and will not be displaced or toppled due to external interference, and can also protect the operator from accidental injury, improving the safety of the entire detection process.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0033] As Figure 1 - Figure 11 shown, a bearing capacity detection device for a lightweight wallboard includes a gantry 1. Inside the gantry 1, there are two lifting columns 2 rotatably connected. The two lifting columns 2 are respectively located on both sides inside the gantry 1. A lifting frame 3 is drivingly connected to the lifting columns 2. A pressure plate 4 is fixedly connected to the lower part of the lifting frame 3. A pressure sensor is arranged inside the pressure plate 4. A hydraulic cylinder 5 is fixedly connected to the top of the gantry 1. The output end of the hydraulic cylinder 5 is fixedly connected to the lifting frame 3. The bottom of the gantry 1 is rotatably connected to a wallboard clamping mechanism 7 through a first sliding sleeve seat 6. A wallboard conveyor belt 8 is arranged on one side of the bottom of the gantry 1. The wallboard conveyor belt 8 is at the same height as the wallboard clamping mechanism 7. Thus, the wallboard to be tested 31 can be laid down on the wallboard conveyor belt 8 and automatically conveyed to the wallboard clamping mechanism 7 for clamping and installation without manual handling.

[0034] Embodiment 1: Sliding sleeves 301 are fixedly connected to both ends of the lifting frame 3. The lifting columns 2 pass through the sliding sleeves 301. A spiral groove 201 is opened on the outer side of the lifting columns 2. A spiral slider 302 is machined on the inner wall of the sliding sleeves 301. The spiral slider 302 is slidably connected to the spiral groove 201. Thus, when the hydraulic cylinder 5 drives the lifting frame 3 to descend, under the cooperation of the spiral slider 302 and the spiral groove 201, the sliding sleeves 301 and the lifting columns 2 will rotate relative to each other. Since the sliding sleeves 301 are fixedly connected to the lifting frame 3 and the lifting columns 2 are rotatably connected to the gantry 1, the lifting columns 2 will rotate.

[0035] A first bevel gear 9 is fixedly connected to the bottom end of the lifting column 2. The first bevel gear 9 meshes with a second bevel gear 10. The second bevel gear 10 is fixedly connected to a first drive shaft 11 through a keyway. A first clutch plate 12 is slidably connected to the first drive shaft 11. Thus, when the lifting column 2 rotates, it will drive the first drive shaft 11 to rotate through the second bevel gear 10. A first chute 1101 is opened on the outer side of the first drive shaft 11. The first clutch plate 12 is slidably connected to the first chute 1101. Thus, the first drive shaft 11 can drive the first clutch plate 12 to rotate together. A first groove 1201 is fixedly connected to the first clutch plate 12. A second convex block 1301 is fixedly connected to the second clutch plate 13. The first groove 1201 and the second convex block 1301 are mutually engaged. The mutual engagement of the first groove 1201 and the second convex block 1301 enables the first clutch plate 12 to drive the second clutch plate 13 to rotate.

[0036] The second clutch plate 13 is slidably connected to the second transmission shaft 14, the second transmission shaft 14 is fixedly connected to the first gear ring 15, the first gear ring 15 is meshed with the first transmission gear 18, the first transmission gear 18 is meshed with the second transmission gear 19, and the second transmission gear 19 is meshed with the second gear ring 20, so that when the first gear ring 15 rotates, it will drive the second gear ring 20 to rotate in the opposite direction. The first gear ring 15 is fixedly connected to the third transmission shaft 17. The wall panel clamping mechanism 7 includes a first clamping block 701 and a second clamping block 702, the first clamping block 701 and the second clamping block 702 are rotatably connected, one first clamping block 701 is provided, and two second clamping blocks 702 are provided, and the two second clamping blocks 702 are respectively located at both ends of the first clamping block 701, and the first clamping block 701 and the second clamping block 702 are respectively located on both sides of the common rotation axis, and the third transmission shaft 17 passes through the second gear ring 20 and the second clamping block 702, and the third transmission shaft 17 is fixedly connected to the first clamping block 701, and the second gear ring 20 is fixedly connected to the second clamping block 702, so that when the lifting frame 3 descends, it will synchronously drive the first clamping block 701 and the second clamping block 702 to rotate, and clamp the wall panel 31 to be tested. The first clamping block 701 and the second clamping block 702 are connected to each other through a dovetail groove with a rubber pad 703 on the inside, and the rubber pad 703 is processed with an anti-slip groove on the outside to prevent sliding. At the same time, after the wall panel 31 to be tested is clamped, the first clamping block 701 and the second clamping block 702 can no longer rotate relative to each other, and the first gear ring 15 and the second gear ring 20 will be stuck, so that the first bevel gear 9 will directly drive the wall panel clamping mechanism 7 to rotate, thereby standing up the wall panel 31 to be tested.

[0037] Embodiment 2: A vertical stop block 21 is arranged at the rear side of two second clamping blocks 702 inside the wall panel clamping mechanism 7. The vertical stop block 21 is fixedly connected to the gantry 1. A telescopic groove 22 is formed in the vertical stop block 21. The telescopic groove 22 penetrates through the vertical stop block 21, and a positioning pressure block 23 penetrates through the telescopic groove 22. One end of the positioning pressure block 23 protrudes outside the telescopic groove 22, and a first inclined slider 24 is fixedly connected to the other end of the positioning pressure block 23. The back surface of the vertical stop block 21 is slidably connected to a sliding rod 26 through a second sliding sleeve seat 25. A second inclined slider 27 is fixedly connected to one end of the sliding rod 26. The second inclined slider 27 and the first inclined slider 24 slide against each other through an inclined surface. A second spring 28 is sleeved outside the sliding rod 26. The second spring 28 is located between the second sliding sleeve seat 25 and the second inclined slider 27. The other end of the sliding rod 26 is fixedly connected to a rotating ring 30 through a connecting rod 29. The rotating ring 30 is rotatably connected to the first clutch plate 12. At the same time, a first chute 1101 is formed on the outer side of the first drive shaft 11. The first clutch plate 12 is slidably connected to the first chute 1101. Thus, when the wall panel to be tested 31 is erected, the second clamping block 702 will be in close contact with the vertical stop block 21, thereby pushing the positioning pressure block 23 and the first inclined slider 24, and then pushing the second inclined slider 27 to move vertically. Thus, the first clutch plate 12 is driven to slide along the first chute 1101 through the connecting rod 29 and the rotating ring 30, so that the distance between the first clutch plate 12 and the second clutch plate 13 increases. The cross-sections of the first groove 1201 and the second convex block 1301 are both trapezoids with one side thick and the other side thin. At the same time, when the positioning pressure block 23 slides in the telescopic groove 22, the maximum sliding distance of the first clutch plate 12 is greater than the length of the shortest side of the first groove 1201 and the second convex block 1301, and less than the length of the widest side of the first groove 1201 and the second convex block 1301. A second chute 1401 is formed on the second drive shaft 14. The second clutch plate 13 is slidably connected to the second chute 1401. A limit retaining piece 1402 is fixedly connected to one end of the second drive shaft 14. A first spring 16 is sleeved outside the second drive shaft 14. The first spring 16 is located between the second clutch plate 13 and the first toothed ring 15. Thus, after the first clutch plate 12 is pushed, when the first clutch plate 12 continues to rotate, the first clutch plate 12 and the second clutch plate 13 will slide, pushing the second clutch plate 13 to the left. Thus, even if the lifting frame 3 continues to descend, the wall panel clamping mechanism 7 will not continue to clamp. Then, once the wall panel to be tested 31 is slightly inclined during the test, the positioning pressure block 23 will pop out again. Thus, the first clutch plate 12 and the second clutch plate 13 will be engaged again, and the wall panel clamping mechanism 7 will quickly clamp and straighten the wall panel to be tested 31 again to prevent the wall panel to be tested 31 from tipping over.

[0038] In addition, when the positioning pressing block 23 slides in the telescopic groove 22, the maximum sliding distance of the first clutch plate 12 is greater than the length of the shortest side of the first groove 1201 and the second convex block 1301, and less than the length of the widest side of the first groove 1201 and the second convex block 1301. This makes the movement range of the first clutch plate 12 and the second clutch plate 13 more precise. When the lifting frame 3 continues to descend during clamping, the wallboard clamping mechanism 7 cannot continue to clamp. However, when the lifting frame 3 ascends during clamping, it can quickly drive the wallboard clamping mechanism 7 to reverse and open, facilitating the placing down of the wallboard 31 to be measured.
