Description

Technical Field

[0001] This utility model relates to the technical field of wall-mounted scaffold support bearing capacity testing, specifically a lifting wall-mounted support bearing capacity testing device based on visual recording. Background Technology

[0002] The wall-mounted scaffold support is an important attachment and support structure for the lifting frame. It can bear and effectively transfer the load of the lifting frame. In order to ensure construction safety, it is necessary to conduct anti-fall and unloading top support tests on the wall-mounted support rods to obtain the design bearing capacity of a single wall-mounted support rod through the test.

[0003] However, the experimental setups used for testing usually obtain the results through static load tests. When an actual attached lifting scaffold falls, the load on the anti-fall support and unloading top brace is an instantaneous impact load. Moreover, it is not convenient to measure and observe the magnitude of the load-bearing capacity obtained from the experiment, nor is it convenient to test the load-bearing capacity at different positions on the support.

[0004] To address this issue, we propose a visual recording-based experimental device for testing the bearing capacity of lifting wall supports. Summary of the Invention

[0005] The purpose of this invention is to provide a visual recording-based experimental device for testing the bearing capacity of lifting wall-mounted supports, in order to solve the problems mentioned in the background art. The experimental devices used for testing obtain the load through static load tests. However, when an actual attached lifting scaffold falls, the load on the anti-fall support and unloading top brace is an instantaneous impact load, which makes it inconvenient to measure and observe the magnitude of the bearing capacity obtained from the experiment, and it is also inconvenient to test the bearing capacity at different positions on the support.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual recording-based lifting wall support bearing capacity test device, comprising a frame-structured testing bracket and a wall support rod disposed at the rear end of the testing bracket;

[0007] Also includes:

[0008] The connecting mechanism is symmetrically arranged on the left and right sides of the rear end of the detection bracket, and the connecting mechanism drives the detection bracket and the wall-mounted support rod to form a disassembly structure.

[0009] The detection structure consists of a movable adjustment plate, a pressure measuring instrument, and a pressure plate located on the front side of the detection bracket.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This visual recording-based lifting wall support bearing capacity test device, through the setting of the connecting mechanism, facilitates the connection of the test bracket with the external wall support rod to be tested.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 .

[0031] To address the problems in existing technologies where testing devices typically rely on static load tests, while actual falls of attached lifting scaffolding result in instantaneous impact loads on the anti-fall supports and unloading top supports, making it difficult to measure and observe the load-bearing capacity obtained from the tests and to test the load-bearing capacity at different locations on the supports, this solution proposes a visual recording-based lifting wall-mounted support load-bearing capacity testing device. This device comprises a frame-structured testing bracket 1 and a wall-mounted support rod 2 located at the rear end of the testing bracket 1. A connecting mechanism is symmetrically positioned on the left and right sides of the rear end of the testing bracket 1, and this connecting mechanism enables a disassembly structure between the testing bracket 1 and the wall-mounted support rod 2. The testing structure consists of a movable adjustment plate 8, a pressure measuring instrument 10, and a pressure plate 12 located at the front of the testing bracket 1. The movable adjustment plate 8 also forms a left-right sliding structure at the front of the testing bracket 1.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the detection bracket 1 and the wall-mounted support rod 2 are first connected by a connecting mechanism. The connecting mechanism is composed of a front clamping block 3, a rear clamping block 4, a support protrusion 5, an auxiliary side plate 6, and a fastening bolt 7. The detection bracket 1 drives the front clamping block 3 to engage with the front side of the wall-mounted support rod 2, and then the rear clamping block 4 engages with the rear side of the wall-mounted support rod 2. At the same time, the middle of the front clamping block 3 and the rear clamping block 4 are provided with support protrusions 5. The front clamping block 3 and the rear clamping block 4 drive the support protrusions 5 to be inserted into the wall-mounted support rod 2. Then, the auxiliary side plates 6 at the upper and lower ends of the front clamping block 3 and the rear clamping block 4 are limited by the fastening bolt 7, which facilitates the limitation between the front clamping block 3 and the rear clamping block 4. The detection bracket 1 can be installed on the front side of the wall-mounted support rod 2 very conveniently.

[0033] After installation, as follows Figure 1 , Figure 5 and Figure 6As shown, by pulling the movable connecting sleeve 13 upward, the movable connecting sleeve 13 slides on the outer surface of the movable adjusting plate 8, and the movable connecting sleeve 13 drives the fixing pin 14 to slide in the movable adjusting plate 8. The fixing pin 14 moves upward and compresses the spring 15, causing the spring 15 to undergo elastic deformation. At this time, the fixing pin 14 moves upward and moves out of the fixing hole 16, thereby releasing the limit between the movable adjusting plate 8 and the detection bracket 1. Then, by pulling the movable adjusting plate 8 to the left or right, the movable adjusting plate 8 slides between the movable adjusting plate 8 and the detection bracket 1, thereby facilitating the adjustment of the position of the movable adjusting plate 8. Moreover, by adjusting the position of the movable adjusting plate 8, it is convenient to detect the bearing capacity at different positions on the wall-mounted support rod 2. When the movable adjusting plate 8 moves to the corresponding position at the front end of the detection bracket 1, the movable connecting sleeve 13 is directly released, the spring 15 returns to its elastic deformation, pushes the fixing pin 14 downward and engages in the fixing hole 16 at the corresponding position on the upper end of the detection bracket 1, thereby facilitating the limit between the movable adjusting plate 8 and the detection bracket 1.

[0034] After the adjustment and limiting between the movable adjustment plate 8 and the detection bracket 1 are completed, they are combined Figure 1 and Figure 2 As shown, the upper end of the movable adjustment plate 8 is connected to the pressure measuring instrument 10 via the first connecting ring 9, and the upper end of the pressure measuring instrument 10 is connected to the pressure plate 12 via the second connecting ring 11. The pressure plate 12 is connected to an external lifting device for applying pressure. By applying upward lifting pressure through the lifting device, the load impact coefficient of the wall-mounted support rod 2 can be detected. The magnitude of the applied pressure, i.e., the magnitude of the load-bearing capacity, can be intuitively displayed through the pressure plate 12 for easy observation. During the detection process, the position of the movable adjustment plate 8 can be adjusted as needed, or one side of the movable adjustment plate 8 can be lifted upward, thereby achieving a more comprehensive detection effect.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
