[0001] This utility model belongs to the field of building construction technology, and specifically relates to a falling object prevention device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] A search revealed a Chinese utility model patent application (CN107989387B) disclosing a construction fall protection device, comprising a fixed base, a filter screen recovery column, and a second filter screen. A lifting rod is fixed to the upper end of the fixed base, and a detachable rotating shaft is connected to the upper end of the lifting rod. A fixing plate is fixed to the upper end of the detachable rotating shaft, and an adhesive tape is connected to the bottom end of the fixing plate. A first filter screen is disposed at the lower end of the adhesive tape. The filter screen recovery column is installed at the lower end of the first filter screen. A reinforcing tape fixing column is installed on the side of the lifting rod away from the center line of the first filter screen, and a reinforcing tape is fixed on the side of the reinforcing tape fixing column away from the lifting rod. A bracket is installed at the lower end of the reinforcing tape, and a motor is fixed to the outer wall of the bracket.

[0004] Regarding the aforementioned technologies, a lifting rod is installed for easy retrieval and reuse. The device is fixed to the bracket by a fixed base and screws at the bottom of the lifting rod, replacing the previous rope binding. However, it cannot effectively move and adjust the first filter screen. Therefore, there is an urgent need to design a falling object prevention device for construction to address these issues. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model discloses a falling object prevention device for building construction.

[0012] Preferably, the telescopic positioning assembly includes an electro-hydraulic rod disposed on the connecting plate, and a positioning pin is provided at the telescopic end of the electro-hydraulic rod.

[0013] Preferably, guide platforms are vertically installed on both sides of the lifting support.

[0014] The beneficial effects are:

[0015] This utility model discloses a falling object prevention device for construction. Through a designed falling object movement mechanism, when an object falls from a height, it lands in the falling object component positioned above a support platform. Due to the weight of the falling object, a moving platform installed on the outer surface of the limiting rod inside the support platform moves, compressing the limiting spring. Simultaneously, a telescopic rod installed on the moving platform pushes an I-beam platform to move relative to the concave groove, lowering the falling object component and the falling platform to buffer the falling object. The elastic platform also cushions the falling object component. Therefore, the falling object component and falling platform effectively buffer the impact of the falling object, preventing it from bouncing and falling back down. This facilitates the removal of falling objects from the falling object component and platform, preventing excessive accumulation that could cause the device to collapse. It is highly practical.

[0024] Reference Figure 1-4One embodiment of this utility model is a falling object prevention device for building construction, including a base 1, a falling object prevention moving mechanism 3 above the base 1, and a supporting lifting mechanism 2 below the base 1.

[0025] In this embodiment: the supporting lifting mechanism 2 includes a lifting column 203 fixedly mounted above the base 1. A square frame 201 is provided on the outer surface of the lifting column 203. A jack 202 is vertically mounted inside the square frame 201 and installed at the lower end of the lifting column 203. A connecting plate 204 is longitudinally arranged below the square frame 201. A telescopic positioning component is installed on the connecting plate 204. A support platform 207 is provided on one side of the telescopic positioning component and installed on the connecting plate 204. The telescopic positioning component includes an electro-hydraulic rod 205 provided on the connecting plate 204. A positioning pin 206 is provided at the telescopic end of the electro-hydraulic rod 205. Guide platforms 2031 are vertically arranged on both sides of the lifting column 203. The guide platforms 2031 are used to guide the movement of the lifting column 203 on the square frame 201.

[0026] In this embodiment: the fall-prevention moving mechanism 3 includes a support platform 302 disposed above the base 1, a damping spring 301 disposed between the support platform 302 and the base 1, a concave groove 307 horizontally disposed below the support platform 302, an I-beam 308 disposed within the concave groove 307, a limit rod 303 horizontally disposed within the support platform 302, a limit spring 304 disposed on the outer surface of the limit rod 303, a moving platform 305 mounted on the outer surface of the limit rod 303, a telescopic rod 306 installed between the moving platform 305 and the I-beam 308, a fall-prevention component mounted above the support platform 302, a fall-prevention platform 310 disposed above the fall-prevention component, and an elastic platform 311 disposed below the fall-prevention component. The fall-prevention component includes a fall-prevention plate 309 disposed above the support platform 302, and a fall-prevention net 3091 mounted above the fall-prevention plate 309. The elastic platform 311 is used to support the descent of the fall-prevention plate 309. The concave groove 307 and the I-beam platform 308 are slidably connected, and the fall arrestor platform 310 is made of soft rubber material. A soft cushioning material is installed on one side of the movable platform 305. Both the fall arrestor net 3091 and the fall arrestor platform 310 are made of soft materials, effectively cushioning and protecting falling objects. The fall arrestor plate 309 and the fall arrestor net 3091 are connected by detachable bolts, facilitating the replacement of the fall arrestor net 3091 from the fall arrestor plate 309.

[0027] Working principle: In use, first move the device to the location where the falling object needs to be prevented. Activate the electric hydraulic rod 205 to push the positioning pin 206 deep into the ground for fixation. The support platform 207 simultaneously supports the device. Activate the jack 202 to push the lifting support column 203 to move up and down within the square frame 201. Stop when the device has risen to a certain height. During fall prevention, gravel and loose cement mortar will fall into the fall prevention platform 310 and the fall prevention net 3091. Because the gravel and loose cement mortar have a certain weight, the gravel and loose water... When mortar falls into the fall arrest net 3091, the fall arrest plate 309 moves downward, causing the support platform 302 to move downward as well. This compresses and buffers the damping spring 301. The telescopic rod 306 pulls the moving platform 305 to move on the outer surface of the limiting rod 303. The moving platform 305 also compresses the limiting spring 304, pushing the I-beam platform 308 to move relative to each other within the concave groove 307. By utilizing the elastic potential energy of the damping spring 301, the fall arrest platform 310 and the fall arrest net 3091 can buffer the downward movement of the support platform 302 when subjected to impact, thus achieving a shock absorption effect.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
