Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding load tests, and particularly to a scaffolding load test device. Background Art

[0002] A scaffolding is a temporary construction tool erected at a construction site for workers to operate and solve vertical and horizontal transportation problems. The installed scaffolding needs to be tested for its load because not only people need to stand on the scaffolding, but also goods need to be placed. In the fields where scaffolding can be used, most of these goods are heavy. Therefore, the installed scaffolding needs to be tested for its load. Currently, a universal testing machine is generally used for pressure application. However, it is often difficult to fixedly install a portal scaffolding during the test, and it often undergoes lateral slip when under pressure, resulting in inaccurate test results and may cause the portal scaffolding to slip and injure the tester, with relatively low safety.

[0003] After retrieval, CN208887910U provides a portal scaffolding load test device, which includes a universal testing machine, an upper pressure beam horizontally connected to the bottom of the moving crossbeam of the universal testing machine, and a supporting beam horizontally fixed below the upper pressure beam; the upper pressure beam is parallel to the supporting beam, and a first card slot extending along the axial direction is provided on the lower side of the upper pressure beam, and a second card slot extending along the axial direction is provided on the upper side of the supporting beam; a first slider is movably provided at each end of the first card slot, and a first insertion rod for inserting into the upper end of the portal scaffolding column is provided at the bottom of the first slider; a second slider is movably provided at each end of the second card slot, and a second insertion rod for inserting into the lower end of the portal scaffolding column is provided at the top of the second slider.

[0004] However, the above publicly disclosed device cannot perform a load test. Secondly, when continuously applying pressure, for the columns of the scaffolding, when the critical value of the scaffolding is exceeded, that is, the columns of the scaffolding will suddenly break.

Two parallel threaded rods 32 are rotatably arranged on the side wall of the U-shaped plate 3, and one end of the threaded rod 32 is movably connected to the extrusion plate 31.

[0034] Refer to Figure 1 , Figure 4 andFigure 5 , four parallel fixed columns 11 are fixedly arranged on the bottom plate 1, and each fixed column 11 is evenly distributed at each corner of the bottom plate 1. An anti-slip plate 12 is fixedly arranged at the bottom end of the fixed column 11. Through the four fixed columns 11 arranged on the bottom plate 1, the supporting function of the whole device is realized. At the same time, each fixed column 11 is arranged at the corner of the bottom plate 1, so that each fixed column 11 can be evenly stressed during the supporting process of the device, avoiding the situation that the fixed column 11 is damaged due to uneven stress during the supporting process. At the same time, the anti-slip plate 12 arranged at the bottom end of the fixed column 11 can increase the friction between the device and the ground, avoiding the situation of slipping when the device is in use.

[0035] Refer to Figures 3-5 , a long plate 4 is fixedly arranged on the bottom plate 1. A first fixed plate 41 is rotatably arranged on the long plate 4.

An arc-shaped groove 51 is opened on the side wall of the first fixed plate 41, and the limit shaft 5 penetrates between the two arc-shaped grooves 51. Through the arc-shaped groove 51 arranged on the first fixed plate 41, when the hydraulic cylinder 27 operates, the limit shaft 5 fixedly arranged at its output end can move along the arc-shaped groove 51, so as to realize the adjustment of the unfolding angle of the first fixed plate 41.

[0038] Refer to Figures 6-8, an adjusting plate 6 is fixedly arranged on the bottom plate 1. A sliding groove 65 is formed in the adjusting plate 6.

The protection plate 45 is fixedly connected with the other end of the sliding rod 61 through a connecting rod 64. By means of the sliding groove 65 arranged on the adjusting plate 6, when the first fixing plate 41 rotates, the sliding rod 61 slidably connected with the first fixing plate 41 moves, and the protection plate 45 is driven by the connecting rod 64 to arch outwards, ensuring that the fragments will not splash.

[0039] Refer to Figures 1-3 , both the first fixing plate 41 and the second fixing plate 42 are arc-shaped, and both the first fixing plate 41 and the second fixing plate 42 are made of alloy materials with strong toughness. By setting both the first fixing plate 41 and the second fixing plate 42 to be arc-shaped, when the first fixing plate 41 rotates, the protection plate 45 can be in an arched state.

[0040] Refer to Figures 1-3 , a heating plate is fixedly arranged on the protection plate 45, and the area of the heating plate is not less than the area between the upper pressing plate 25 and the lower pressing plate 23. By means of the heating plate arranged on the protection plate 45, it is realized that the device to be processed and detected can simulate the influence of a high-temperature external environment on the material.

[0041] Refer to Figures 1-3 , a connecting groove 261 is formed in the side wall of the support plate 22, and the second fixing plate 42 is in contact with the side wall of the connecting groove 261. By means of the connecting groove 261 arranged on the support 26, the moving direction of the lower pressing plate 23 is controlled.

[0042] Refer to Figure 3 and Figure 8 , the elongation of the hydraulic cylinder 27 is not less than the length of the connecting groove 261. By setting the length relationship between the hydraulic cylinder 27 and the connecting groove 261, it is ensured that the device can operate normally.

[0043] The specific solution of this scheme is as follows: When using the device, the staff first move the device to a suitable position for fixation. Through the four fixing columns 11 arranged on the bottom plate 1, the overall support function of the device is realized. At the same time, each fixing column 11 is arranged at the corner of the bottom plate 1, so that each fixing column 11 can be evenly stressed during the support process of the device, avoiding the situation that the fixing column 11 is damaged due to uneven stress during the support process. At the same time, the anti-slip plate 12 arranged at the bottom end of the fixing column 11 can increase the friction between the device and the ground, avoiding the situation of slipping when the device is in use. When installing the device, first fixedly connect the protection plate 45 between the first shaft 43 and the second shaft 44. And through the protection plate 45, when the scaffolding bursts during the operation of the device, the protection plate 45 can prevent the material fragments from splashing, avoiding damage to the staff and improving the overall safety of the device. When the hydraulic cylinder 27 operates, the limiting shaft 5 fixedly arranged on its output end can move along the arc-shaped groove 51, so as to realize the adjustment of the unfolding angle of the first fixing plate 41. Through the sliding groove 65 arranged on the adjusting plate 6, as the first fixing plate 41 rotates, the sliding rod 61 slidably connected to the first fixing plate 41 moves, and drives the protection plate 45 to arch outwards through the connecting rod 64, ensuring that the fragments will not splash.
