Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a weighable safe intelligent hydraulic protection platform and a construction method thereof. Background Art

[0002] During the construction of a building structure, the construction protection platform is installed on the outside of the structure as a worker operating platform and safety protection. The liftable protection platform is generally powered by manpower, electric power, or hydraulic power, and is lifted layer by layer as the building structure is constructed. The protection platform is generally connected to the outer wall or floor slab of the structure through high-strength bolts. Since the protection platform is also used as a safety protection for structural construction, its protection height is generally 1.5 times the floor height.

[0003] According to JGJ 202-2010 "Technical Specifications for Safety of Tool-type Scaffolds in Construction", 4.8 stipulates that the construction load on the frame should comply with the design requirements, and no overload or concentrated load that affects the safety of the scaffolding members should be placed. Therefore, it is very necessary to monitor the load on the protection platform.

[0004] The load monitoring system of the traditional construction protection platform is mainly used to monitor the load of the protection frame acting on the lifting device when the protection platform is climbing or lifting. This type of load monitoring system can only limit the load when the protection frame is lifted to ensure the safety of the protection frame when lifting and avoid accidents caused by the jamming of individual climbing mechanisms.

[0005] Some people have proposed relevant solutions for monitoring the load during the construction process. Chinese patent document CN201991207 U provides an "Attached Lifting Scaffold Load Alarm", which includes an attached support device, and the attached support device includes a support cantilever, and the support cantilever is provided with a support top rod, and the support top rod supports the main frame of the scaffold. This solution can obtain the load data of each support position through a pin sensor installed at the connection of the support top rod.

[0006] Since the protection frames have multiple supports and are hyperstatic structures, pin sensors need to be placed at each support rod position and processed by calculation to obtain the correct load value. Therefore, the current protection platform load monitoring solution still has room for improvement. Summary of the invention

[0007] The purpose of the present invention is to provide a weighable safe intelligent hydraulic protection platform and its construction method, so as to solve the problem that since the protection frames have multiple supports and are hyperstatic structures, it is necessary to arrange pin sensors at each support rod position and calculate and process them to obtain the correct load value. Therefore, the current protection platform load monitoring solution still has room for improvement.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a weighable, safe, intelligent hydraulic protection platform and a construction method thereof, comprising a tensile and compressive sensor housing, a sensor mounting structure being installed inside the tensile and compressive sensor housing, guide structures being arranged on the front and back sides of the right end of the tensile and compressive sensor housing, and a supporting structure being connected to the left side of the tensile and compressive sensor housing.

[0009] The sensor installation structure includes a mounting unit and a limiting unit.

[0010] The installation unit comprises an oblong hole, a tension and compression sensor connecting pin is installed inside the oblong hole, and a tension and compression sensor is connected to the outer surface of the tension and compression sensor connecting pin.

[0011] Preferably, the limiting unit comprises a limiting protrusion, and a limiting pin of the tension and compression sensor housing is arranged at the right bottom of the limiting protrusion.

[0012] Preferably, the right side of the limit protrusion is fixedly connected to the middle of the left side of the tension and compression sensor housing near the top, and the limit pin of the tension and compression sensor housing is arranged inside a through hole opened in the middle of the front side of the tension and compression sensor housing near the bottom, and the limit pin of the tension and compression sensor housing is connected to the bottom of the tension and compression sensor.

[0013] Preferably, the guide structure includes a guide rail, a guide rail circular hole is provided on the front side of the guide rail near the right end, and a guide rail long hole is provided on the left end of the front side of the guide rail.

[0014] Preferably, the two guide rails are connected to the front and back sides of the tension and compression sensor housing on one side close to each other, the guide rail circular holes and the guide rail circular holes are arranged in a longitudinal array, and the guide rail circular holes and the guide rail long holes are arranged relatively staggered.

[0015] Preferably, the supporting structure includes a load-bearing pin, a floor attachment support is provided on the left side of the load-bearing pin, and the bottom of the floor attachment support is connected to the building structure.

[0016] Preferably, the right end of the floor attachment support is connected to the left side of the tension and compression sensor housing, and the top end of the load-bearing pin is connected to the limiting protrusion.

[0017] Preferably, S1: the guide rail of the hydraulic protection platform is provided with circular holes with fixed spacing, and the housing of the tension and compression sensor is provided with oblong holes with fixed spacing, the center distance of the oblong holes on the tension and compression sensor is the same as the center distance of the circular holes on the guide rail, the tension and compression sensor is installed inside the guide rail and fixed by the circular holes on the guide rail. At this time, since the opening on the housing of the tension and compression sensor is an oblong hole, the housing of the tension and compression sensor can still be displaced up and down inside the guide rail after installation.

[0018] S2: There is a limit protrusion on one side of the tension and compression sensor housing. When weighing, the limit protrusion cooperates with the load-bearing pin, and the load-bearing pin falls on the floor attachment support. At this time, the tension and compression sensor housing is fixed relative to the structure, and the neutral position of the protective frame will be transmitted to the tension and compression sensor through the guide rail, causing it to deform.

[0019] S3: The tension and compression sensor is installed inside the tension and compression sensor housing, and can convert tensile strain or compressive strain into electrical signals for monitoring. One end of the tension and compression sensor is fixed relatively to the guide rail, and the other end is fixed relatively to the tension and compression sensor housing. One end of the tension and compression sensor, together with the guide rail, produces a vertical downward displacement relative to the structure under the action of the gravity of the protective frame. The magnitude of the displacement is equal to the tensile strain or compressive strain value of the tension and compression sensor.

[0020] S4: By reversing the installation direction of the tension and compression sensor and changing the position of the fixed end of the tension and compression sensor, the tension and compression sensor can be converted between detecting tensile stress or compressive stress. The sensor electrical signal is connected to a dedicated processing device through a signal line, and then through a wireless Internet of Things system to achieve real-time monitoring and access to construction load information. In actual use, relevant technicians can access the corresponding load collection points through a mobile phone APP.
