Description

Technical Field

[0001] The invention relates to the technical field of scaffolding load testing, in particular to a scaffolding load testing device. Background Art

[0002] Scaffolding is a temporary construction tool set up at the construction site for workers to operate and solve vertical and horizontal transportation. The installed scaffolding needs to be tested for load, because not only people need to stand on the scaffolding, but also goods need to be placed. In the field where scaffolding can be used, most of the goods are very heavy. Therefore, the installed scaffolding needs to be tested for load. At present, universal testing machines are generally used for pressure application. However, gantry scaffolding is often difficult to fix and install during the test, and it often slips laterally when under pressure, resulting in inaccurate test results, and may cause the gantry scaffold to slip and injure the tester, which is less safe.

[0003] After searching CN208887910U, a gantry scaffolding load testing device is provided, including 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, the lower side of the upper pressure beam has a first slot extending axially, and the upper side of the supporting beam has a second slot extending axially; a first slider is movably provided at both ends of the first slot, and a first plug rod for being plugged into the upper end of a gantry scaffolding column is provided at the bottom of the first slider; a second slider is movably provided at both ends of the second slot, and a second plug rod for being plugged into the lower end of a gantry scaffolding column is provided at the top of the second slider.

At the same time, each fixing column 11 is arranged at the corner of the base plate 1 so that each fixing column 11 can be evenly stressed during the support process of the device, thereby avoiding damage to the fixing column 11 due to uneven force during the support process. At the same time, the anti-skid plate 12 arranged on the bottom end of the fixing column 11 can increase the friction between the device and the ground, thereby avoiding the device from slipping during use.

Through the arc groove 51 arranged on the fixed plate 41, when the hydraulic cylinder 27 is operating, the limit shaft 5 fixedly arranged on its output end can move along the arc groove 51, thereby adjusting the expansion angle of the fixed plate 41.

[0038] Reference Figure 6-Figure 8An adjusting plate 6 is fixedly arranged on the bottom plate 1, a slide groove 65 is provided on the adjusting plate 6, a sliding rod 61 is slidably arranged on the slide groove 65, a guide plate 62 is fixedly arranged on one end of the sliding rod 61 close to the carrying plate 2, a guide groove 63 is provided on the guide plate 62, the shaft body 44 is slidably connected with the guide groove 63, the protective plate 45 and the other end of the sliding rod 61 are fixedly connected by a connecting rod 64, and the slide groove 65 provided on the adjusting plate 6 is realized, as the fixed plate 41 rotates, the sliding rod 61 slidably connected with the fixed plate 41 moves, and the protective plate 45 is driven to be arched outward by the connecting rod 64 to ensure that debris will not splash.

[0039] Reference Figure 1-Figure 3 The fixing plate 1 41 and the fixing plate 2 42 are both arranged in an arc shape, and the fixing plate 1 41 and the fixing plate 2 42 are both arranged in an arc shape. By arranging the fixing plate 1 41 and the fixing plate 2 42 in an arc shape, the protective plate 45 can be in an arched state when the fixing plate 1 41 rotates.

[0040] Reference Figure 1-Figure 3 A heating plate is fixedly arranged on the protective 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 setting the heating plate on the protective plate 45, the device to be processed and tested can be controlled to simulate the influence of the high temperature external environment on the material.

[0041] Reference Figure 1-Figure 3 A connecting groove 261 is provided on the side wall of the support plate 22, and the fixing plate 42 is in contact with the side wall of the connecting groove 261. The moving direction of the lower pressing plate 23 is controlled by the connecting groove 261 provided on the bracket 26.

[0042] Reference Figure 3 and Figure 8 The extension 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 is as follows: when using the device, the staff first moves the device to a suitable position for fixing. The four fixing columns 11 arranged on the base plate 1 realize the support function of the entire device. At the same time, each fixing column 11 is arranged at the corner of the base plate 1 so that each fixing column 11 can be evenly stressed during the support process, thereby avoiding damage to the fixing column 11 due to uneven stress during the support process. At the same time, the anti-skid plate 12 arranged at the bottom end of the fixing column 11 can increase the friction between the device and the ground, thereby avoiding the device from slipping during use. When installing the device, the protective plate 45 is first fixedly set and connected between the shaft body 1 43 and the shaft body 2 44, and the protective plate 45 is used to prevent the scaffold from bursting during the operation of the device. In order to prevent material fragments from splashing, avoid injury to the staff and improve the overall safety of the device. When the hydraulic cylinder 27 is operating, the limit shaft 5 fixed on its output end can move along the arc groove 51, so as to adjust the expansion angle of the fixed plate 41, which is achieved by the slide groove 65 set on the adjustment plate 6. As the fixed plate 41 rotates, as the hydraulic cylinder 27 continues to extend, the expansion angle of the two mirror-image fixed plates 41 continues to expand, so that the shaft body 43 movably connected to the fixed plate 41 is adjusted. At this time, the position of the shaft body 43 remains in an upward state, and as the distance between the shaft body 43 and the shaft body 2 44 gradually decreases, the protective plate 45 begins to bend, and the protective plate 45 is driven to arch outward through the connecting rod 64 to ensure that the fragments do not splash.
