Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a safety fall prevention device for building construction. Background Art

[0002] As my country's urbanization process continues to accelerate, high-rise buildings will appear in front of us more and more frequently, and construction workers will also face more severe high-altitude working environments. The characteristics of construction are large workloads at heights, complex and changeable working environments, high labor intensity in manual operations, and many dangerous factors in multi-type cross-operations, which make safety accidents very easy to occur. Therefore, the construction industry is one of the most dangerous industries in my country.

[0003] The existing patent (publication number: CN216811088U) discloses a safe anti-fall protection device for construction, including a device body, which includes a bracket, a support rod and a sliding rod. A slide groove is opened on the inner side of the bracket, and a spring 1 is installed on the inner side of the slide groove. A support block is welded on one side of the sliding rod, a hydraulic rod is installed on the top of the support block, and a connecting block is installed on the top of the hydraulic rod. A baffle rod is arranged on the top of the support rod, and a spring 2 is installed on the bottom of the baffle rod. A protective net is connected to one side of the support rod.

[0004] The above-mentioned comparative document points out that the device can use the baffle rod and spring to cushion when a person accidentally falls on the top of the support pole, and prevent the person from hitting the support pole, thereby avoiding injuries caused by the person hitting the support pole. The protective net can be retracted when transporting construction materials and equipment to the construction layer at the top of the building, without the need to bypass the protective net from a distance, thereby ensuring the transportation efficiency of construction materials and equipment. It is suitable for safe fall prevention in construction. However, the device does not have a blocking device on one side of the protective net. When a person accidentally falls, he loses balance and is prone to rolling, which may cause him to roll out of the protection range of the protective net. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a safety fall prevention device for construction use, which has the advantage of preventing people from rolling down from the protective net. It solves the problem that the device does not have a blocking device on one side of the protective net. When a person accidentally falls, he loses balance and is prone to rolling, which may cause him to roll out of the protection range of the protective net.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a safety anti-fall device for construction, comprising a floor, a first rotating seat fixedly connected to one side of the floor, a rotating shaft rotatably connected inside the first rotating seat, first support rods rotatably connected to both ends of the outer wall of the rotating shaft, two first support rods rotatably connected to one end away from the rotating shaft, and two pull rods rotatably connected to one end away from the first support rod.

[0007] A guardrail is fixedly connected to the upper end of the floor, and both ends of one side of the guardrail are fixedly connected to a second rotating seat. The ends of the two connecting rods away from the pull rod are rotatably connected to the second rotating seat, a cross bar is fixedly connected between the two pull rods, and the two first support rods and the upper ends of the pull rods are fixedly connected to an anti-fall net.

[0008] Through the above scheme, through the arrangement of the first support rod, the pull rod and the connecting rod, when the anti-fall net is opened, the pull rod is pulled by the connecting rod to rotate one end of the first support rod, and drive one end of the anti-fall net to tilt up, so as to prevent the possible rolling when a person accidentally falls from a height, and then rolls out of the protection range of the protective net, and through the rotational connection between the first support rod, the pull rod and the connecting rod, the anti-fall net can dynamically adjust its shape and angle as needed, thereby improving the safety of the construction site.

[0009] Furthermore, the bottom ends of the two first support rods are fixedly connected to a third rotating seat, and the two third rotating seats are rotatably connected to the second support rods.

[0010] Through the above solution, the second support rod can rotate inside the third rotating seat.

[0011] Furthermore, four legs are fixedly connected to the bottom end of the floor.

[0012] Through the above solution, the legs are arranged to support the floor.

[0013] Furthermore, one side of the two legs is fixedly connected to a fixing box, and both sides of the two fixing boxes are provided with sliding grooves.

[0014] Through the above scheme, the fixed box and the slide groove are used to install the buffer device.

[0015] Furthermore, two springs are fixedly connected to the upper ends of the bottoms of the two fixed boxes, and the upper ends of the four springs are fixedly connected to sliding boxes in groups of two. Fixed blocks are fixedly connected inside the two sliding boxes, and slots are provided inside the two fixed blocks.

[0016] Through the above scheme, the spring design at the upper end of the bottom of the fixed box enables the device to have the ability of buffering and shock absorption. When a person falls, the spring can absorb and disperse these forces, thereby reducing the vibration of the anti-fall net and protecting the construction workers from secondary injuries.

[0017] Furthermore, both sides of the two sliding boxes are fixedly connected with sliding bars, a plurality of the sliding bars are slidably arranged inside the sliding grooves, and the two sliding boxes are slidably arranged inside the fixed box.

[0018] With the above solution, the slide groove and the slide bar cooperate with each other, so that the slide box is more stable when sliding inside the fixed box, and is not prone to shaking or dislocation.

[0019] Furthermore, the four legs are fixedly connected with a support frame in groups of two, and the bottom ends of one side of two legs are fixedly connected with a support leg.

[0020] Through the above solution, the addition of the support frame and the support legs enhances the load-bearing capacity of the entire device, and jointly shares the weight of the device and the anti-fall net, so that the device can withstand a greater weight.

[0021] Furthermore, one end of the two second support rods away from the third rotating seat is slidably disposed inside the slot.

[0022] Through the above solution, the second support rod is inserted into the slot to ensure that the second support rod is fixed, so that the device can remain stable during use and is not prone to accidental movement or shaking, thereby improving construction safety.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The safety anti-falling device for construction use has a first support rod, a pull rod and a connecting rod. When the anti-falling net is opened, the pull rod is pulled by the connecting rod to rotate one end of the first support rod and drive one end of the anti-falling net to tilt up, so as to prevent the possible rolling when a person accidentally falls from a height and then rolls out of the protection range of the protection net. The anti-falling net can dynamically adjust its shape and angle as needed through the rotation connection between the first support rod, the pull rod and the connecting rod, thereby improving the safety of the construction site.

[0033] See also Figure 2 , Figure 3 and Figure 4 The bottom ends of the two first support rods 4 are fixedly connected to the third rotating seat 11, the two third rotating seats 11 are internally rotatably connected to the second support rods 12, the second support rods 12 can rotate inside the third rotating seat 11, and the bottom end of the floor 1 is fixedly connected to four legs 13, the legs 13 are set to support the floor 1, and one side of the two legs 13 is fixedly connected to a fixing box 14.

[0034] See also Figure 4, slide grooves 15 are provided inside the two sides of the two fixed boxes 14, and the fixed boxes 14 and the slide grooves 15 are used to install buffer devices. Two springs 16 are fixedly connected to the upper ends of the bottoms of the two fixed boxes 14, and four springs 16 are fixedly connected to the upper ends of a group of two. A sliding box 17 is fixedly connected to the two sliding boxes 17, and a fixed block 18 is fixedly connected to the inside of the two sliding boxes 17. A slot 19 is provided inside the two fixed blocks 18. The spring 16 at the upper end of the bottom of the fixed box 14 is designed to enable the device to have the ability of buffering and shock absorption. When a person falls, the spring 16 can absorb and disperse these forces, thereby reducing the vibration of the anti-fall net 10 and protecting the construction personnel from secondary injuries. Slide bars 20 are fixedly connected to both sides of the two sliding boxes 17, and multiple slide bars 20 are slidably arranged inside the slide grooves 15. The two sliding boxes 17 are slidably arranged inside the fixed box 14. Through the cooperation between the slide grooves 15 and the slide bars 20, the sliding box 17 is more stable when sliding inside the fixed box 14, and is not prone to shaking or dislocation.

[0035] See also Figure 1 and Figure 3 The four legs 13 are fixedly connected with a support frame 21 in pairs, and the bottom end of one side of the two legs 13 is fixedly connected with a support leg 22. The addition of the support frame 21 and the support leg 22 enhances the load-bearing capacity of the entire device, and jointly shares the weight of the device and the anti-fall net 10, so that the device can withstand a greater weight. The ends of the two second support rods 12 away from the third rotating seat 11 are both slidably set in the slot 19, and the second support rod 12 is inserted into the slot 19 to ensure that the second support rod 12 is fixed, so that the device can remain stable during use and is not prone to accidental movement or shaking, thereby improving the safety of construction.

[0036] In this embodiment, the safety anti-falling device for construction use is provided with a first support rod 4, a pull rod 5 and a connecting rod 6. When the anti-falling net 10 is opened, the pull rod 5 is pulled by the connecting rod 6 to rotate one end of the first support rod 4, and drive one end of the anti-falling net 10 to tilt up, so as to prevent the rolling that may occur when a person accidentally falls from a height, and then rolls out of the protection range of the protective net. Through the rotational connection between the first support rod 4, the pull rod 5 and the connecting rod 6, the anti-falling net 10 can dynamically adjust its shape and angle as needed, thereby improving the safety of the construction site.

[0037] It should be noted that the protective net is arranged at the opening of the guardrail 7 .

[0038] The working principle of the above embodiment is:

[0039] When it is necessary to unfold the anti-fall net 10, the operator can pull the connecting rod 6. Since the connecting rod 6 and the pull rod 5 as well as the pull rod 5 and the first support rod 4 are all rotatably connected, pulling the connecting rod 6 will drive the pull rod 5 to rotate at the end of the first support rod 4. This rotation will cause one end of the anti-fall net 10 to tilt up, thereby forming an open net surface. The cross bar 9 is fixed between the two pull rods 5 to enhance stability and ensure that the anti-fall net 10 can maintain a stable shape after unfolding. When a construction worker accidentally falls and hits the anti-fall net 10, the anti-fall net 10 will move downward and compress the spring 16 at the bottom of the fixed box 14. The design of the spring 16 It is to absorb and disperse the force generated during the impact, thereby reducing the vibration of the anti-fall net 10. At the same time, the fixed block 18 inside the sliding box 17 will slide downward along the slide groove 15 under the compression of the spring 16. The cooperation between the slide bar 20 and the slide groove 15 ensures the stability of the sliding box 17 during the sliding process to prevent it from shaking or dislocation. The legs 13 are connected by a support frame 21 to enhance the load-bearing capacity of the device. At the same time, the addition of the support leg 22 further improves the stability of the device. The second support rod 12 can be inserted into the slot 19 to ensure that the second support rod 12 is fixed, so that the device remains stable during use and is not prone to accidental movement or shaking.
