Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The purpose of this invention is to provide an unloading platform to solve the problems existing in the prior art and to make the unloading platform safer.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This invention provides an unloading platform, such as Figures 1-4 As shown, the structure includes a cantilever beam 2 and an energy-absorbing pin 3. The building structure has a structural beam 1. At least a portion of the side of the structural beam 1 facing outwards is attached to and fixedly connected to one end face of the cantilever beam 2. The end of the cantilever beam 2 away from the structural beam 1 is suspended. A first mounting groove 11 is formed on the contact surface between the structural beam 1 and the cantilever beam 2, and a second mounting groove 21, directly opposite the first mounting groove 11, is formed on the contact surface between the cantilever beam 2 and the structural beam 1. A portion of the energy-absorbing pin 3 is located inside the first mounting groove 11, and another portion is located inside the second mounting groove 21. A strain gauge 33 is mounted on the energy-absorbing pin 3, with the working end of the strain gauge 33 corresponding to the contact surface between the structural beam 1 and the cantilever beam 2. After the cantilever beam 2 is installed, a steel plate or steel mesh can be laid on it, and guardrails and protective doors can be installed on the steel plate, thus completing the overall installation of the unloading platform.

[0027] The unloading platform provided by this invention, by setting energy-absorbing pins 3 at the connection between structural beam 1 and cantilever beam 2, allows the platform to bear materials. When the platform is loaded with materials, the energy-absorbing pins 3, structural beam 1, and cantilever beam 2 share the load and deform together. Strain gauges 33 can then measure the stress value at the connection between the energy-absorbing pins 3 and structural beam 1 and cantilever beam 2. When the stress value is high and reaches a warning threshold, operation must be stopped and the mass of materials carried by the platform reduced, thus improving platform safety. Therefore, the unloading platform provided by this invention, by utilizing strain gauges 33 to monitor the platform's load-bearing status in real time, can provide early warnings and offers high safety.

[0028] Specifically, the cantilever beam 2 preferably uses a T-shaped beam, the second mounting groove 21 extends from the flange of the cantilever beam 2 to the web; the flange of the cantilever beam 2 is provided with bolt holes, and the bolt holes of the structural beam 1 correspond to the bolt holes on the cantilever beam 2; the strain gauge 33 is an optical fiber Bragg grating strain gauge 33, and the strain gauge 33 is signal connected with the external monitoring device, so that the stress and deformation of the energy-absorbing pin 3 can be monitored in real time through the detection device.

[0029] In a preferred embodiment of the present embodiment, the energy-absorbing pin 3 includes a pin body 31 and two energy-absorbing assemblies 32, a part of the pin body 31 is arranged inside the first mounting groove 11, and another part is arranged inside the second mounting groove 21, the strain gauge 33 is arranged on the side surface of the middle part of the pin body 31, and the two energy-absorbing assemblies 32 are respectively located on the two sides of the strain gauge 33, each energy-absorbing assembly 32 extends from the two ends of the pin body 31 along the side surface of the pin body 31 to the working end, and the two ends of each energy-absorbing assembly 32 are fixedly connected to the pin body 31. The energy-absorbing assembly 32 has elasticity. When the unloading platform carries a large amount of material at one time, and the bearing capacity of the connection is insufficient, the energy-absorbing pin 3 can absorb energy by using the elastic energy-absorbing assembly 32, thereby giving the unloading platform a strong safety energy-absorbing reserve, preventing the connection between the structural beam 1 and the cantilever beam 2 from suddenly breaking and the cantilever beam 2 from overturning relative to the structural beam 1, and giving the user enough time to check and repair.

[0030] In a preferred embodiment of the present embodiment, the unloading platform provided by the present application further includes a sealing beam 4, and a plurality of cantilever beams 2 are arranged on the structural beam 1 in the horizontal direction, preferably three cantilever beams 2, the end of the cantilever beam 2 away from the structural beam 1 is a cantilever end, and the two ends of the sealing beam 4 are fixedly connected to the cantilever ends of the two adjacent cantilever beams 2, respectively. The sealing beam 4 arranged at the cantilever end connection of the two adjacent cantilever beams 2 can make each cantilever beam 2 form a whole, and the structure composed of the sealing beam 4 and the cantilever beam 2 has higher integrity and more reasonable force transmission path, thereby improving the lateral force resistance of the whole unloading platform. The sealing beam 4 is an I-beam, bolt holes are arranged at the flanges of the I-beam, corresponding bolt holes are arranged on the cantilever beam 2, and the sealing beam 4 and the cantilever beam 2 are connected by bolts.

[0031] In a preferred embodiment of the present embodiment, the structural beam 1 and the cantilever beam 2 are connected by high-strength bolts. Compared with ordinary bolts, high-strength bolts need to be pre-tightened during installation, which can make the connection between the cantilever beam 2 and the structural beam 1 more firm.

Since the installation of high-strength bolts is more difficult than that of ordinary bolts, in order to facilitate the installation of high-strength bolts at the connection between the structural beam 1 and the cantilever beam 2, the first mounting groove 11 and the second mounting groove 21 can be aligned to determine the installation position, and the energy-absorbing pin 3 can be placed into the total mounting groove from the top, then the preliminary clamping and fixing can be formed by using the limiting plates and the limiting surfaces, and then the high-strength bolts can be installed. Compared with directly installing high-strength bolts, this installation method is more convenient, saves the complex steps of multiple positioning, simplifies the construction process, and improves the construction efficiency.

The spring is sleeved on the outside of the pin body 31, which can prevent the side of the pin body 31 from affecting the normal expansion and contraction of the spring, compared with being arranged inside the pin body 31.

One end of the inclined support 5 is connected to one side of the cantilever beam 2, and the other end extends obliquely downward and is connected to the side of the structure beam 1 close to the cantilever beam 2.
