Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular to a fall protection device for building construction. Background Technology

[0002] In the construction industry, especially in the construction, maintenance, and cleaning of the exterior walls of high-rise buildings, suspended platforms are widely used as a common transportation tool for the vertical transport of workers and materials. Traditional construction suspended platforms are usually hoisted by lifting ropes and raised or lowered by electric or manual means.

[0003] However, existing construction suspended platforms have some technical defects, such as: most of them rely on simple ropes and pulleys for lifting and lowering, lacking an effective guiding mechanism. This makes it difficult for the platform to maintain a straight line during ascent or descent, easily deviating from the predetermined track, increasing operational difficulty and safety hazards. The connection between the platform and the supporting structure is mostly direct fixing or simple hooks, which may loosen or be damaged after long-term use, thus affecting the safety of the entire system. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fall protection device for building construction.

[0005] The purpose of this utility model is achieved through the following technical solution: a fall protection device for construction, comprising a construction basket for transporting workers or goods during construction, wherein one side of the construction basket has a fixed travel seat, the back of the fixed travel seat is in close contact with the wall, and ear plates are welded to both ends of the fixed travel seat, and at least two positioning uprights are symmetrically and rotatably installed between the two ear plates, the positioning uprights are connected to the construction basket through sliding connectors, so that the construction basket can slide up and down along the longitudinal extension direction of the fixed travel seat and the positioning uprights, and a hoisting rope is connected to the top of the construction basket, the hoisting rope being connected to a winch on the building through a pulley assembly. When the winch releases the hoisting rope, the construction basket slides down the positioning pole under the action of gravity. When the winch rewinds the hoisting rope, the construction basket rises and slides on the positioning pole. At the same time, an inclined support component is provided on the bottom surface of the construction basket. The end of the inclined support component away from the construction basket makes rolling friction contact with the walls on both sides of the fixed travel seat.

[0006] In this preferred embodiment, both ends of the fixed travel seat are connected to the wall via multiple anchor rods, so that the back of the fixed travel seat is in close contact with the wall.

[0007] Preferably, the sliding connecting piece comprises a sliding block piece slidingly connected to the two positioning vertical rods, and a T-shaped connecting plate welded to one side of the sliding block piece.

[0008] Preferably, a plurality of bolt connecting holes are symmetrically formed in the side of the T-shaped connecting plate away from the sliding block piece.

[0009] Preferably, the top end of the construction basket piece is fixedly connected with four connecting ropes, the top ends of the four connecting ropes are gathered together and connected with a connecting ring, and the bottom end of the hoisting rope is fixedly connected with the connecting ring.

[0010] Preferably, the pulley assembly comprises a pulley bracket fixed above the building and a pulley piece hingedly connected to the free end of the pulley bracket, the free end of the pulley bracket is provided with a hinged notch for mounting the pulley piece, and the pulley piece is hingedly connected to the hinged notch through a pin shaft.

[0011] Preferably, the inclined support part comprises two inclined support rods symmetrically inclinedly welded to the bottom surface of the construction basket piece, a U-shaped clamping plate welded to the free end of the inclined support rod, and a positioning walking wheel hingedly connected to the U-shaped clamping plate.

[0012] Preferably, the two inclined support rods are symmetrically distributed on the two sides of the fixed stroke seat, and the end of the positioning walking wheel away from the U-shaped clamping plate rolls and rubs against the wall. A rubber buffer ring is sleeved on the peripheral outer wall of each positioning walking wheel, and the rubber buffer ring elastically abuts against the wall.

[0013] The beneficial effects of the present application are:

[0014] 1) The sliding connection design between the construction basket piece and the positioning vertical rod ensures that the construction basket piece slowly descends under the action of gravity, rather than suddenly falling. This greatly reduces the risk of accidents and protects the personal safety of workers. The inclined support rod and the positioning walking wheel arranged at the bottom ensure that the construction basket piece remains stable during the ascending or descending process, reducing the possibility of lateral swinging and further improving the safety of operation.

[0015] 2) By firmly installing the fixed stroke seat on the wall and using the positioning vertical rod as the guide rail of the construction basket piece, the straight-line motion of the construction basket piece during the lifting process is ensured, avoiding deviation or shaking caused by lateral force and improving the stability of the entire system. The sliding block piece slides up and down along the positioning vertical rod, and the T-shaped connecting plate is fixedly connected to the construction basket piece through bolts. This structure not only ensures the smooth movement of the construction basket piece, but also provides an additional support point, enhancing the rigidity and torsional performance of the overall structure.

[0016] 3) The design of the pulley support and pulley piece ensures that the hoisting rope can smoothly pass through the pulley, reducing frictional resistance, thereby improving the working efficiency of the hoist. At the same time, this also means less energy loss and faster lifting speed. Due to the improvement of the reliability and safety of the equipment, the downtime caused by failure or accident is reduced, thereby improving the overall working efficiency of the construction site.

[0028] In the embodiment, the top end of the construction basket piece 1 is fixedly connected with four connecting ropes 3, the top ends of the four connecting ropes 3 are gathered at one place and connected with a connecting ring 4, and the bottom end of the hoisting rope 5 is fixedly connected together with the connecting ring 4.

[0029] In the embodiment, the pulley assembly includes a pulley bracket 16 fixed above the building and a pulley 6 hinged at the free end of the pulley bracket 16, the free end of the pulley bracket 16 is provided with a hinged notch for installing the pulley 6, and the pulley 6 is hinged with the hinged notch through a pin shaft.

[0030] In the embodiment, the inclined support component includes two inclined support rods 11 symmetrically inclined and welded to the bottom surface of the construction basket piece 1, a U-shaped clamping plate 12 welded to the free end of the inclined support rod 11, and a positioning walking wheel 13 hinged in the U-shaped clamping plate 12.

[0031] In this embodiment, two inclined support rods 11 are symmetrically distributed on both sides of the fixed stroke seat 2, and the positioning walking wheels 13 are rolled and rubbed on the wall away from one end of the U-shaped clamping plate 12. The outer wall of each positioning walking wheel 13 is sleeved with a rubber buffer ring, which is elastically abutted on the wall.

[0032] Working principle:

[0033] The anti-falling device for building construction tightly abuts the fixed stroke seat 2 to the wall, and uses multiple anchor rods 8 to firmly fix it on the wall of the building, ensuring that it will not displace. Between the ear plates 9 welded on the surfaces of the two ends of the fixed stroke seat 2, at least two positioning vertical rods 7 are symmetrically and rotatably installed, ensuring that they can be perpendicular to the ground and can be connected to the construction basket 1 through sliding connectors. The sliding block 14 is longitudinally and slidably connected on the positioning vertical rod 7, the T-shaped connecting plate 10 is welded on one side of the outer wall of the sliding block 14, and the T-shaped connecting plate 10 and the construction basket 1 are fixed together through bolts, so that the construction basket 1 can slide up and down along the positioning vertical rod 7.

[0034] The bottom surface of the construction basket 1 is symmetrically and obliquely welded with two inclined support rods 11, and the free end of each inclined support rod 11 is welded with a U-shaped clamping plate 12, and the U-shaped clamping plate 12 is hingedly connected with a positioning walking wheel 13. These components ensure that the construction basket 1 remains stable during the ascending or descending process, while the positioning walking wheel 13 rolls and rubs against the wall to reduce shaking.

[0035] Four connecting ropes 3 are fixedly connected at the four corners of the top end of the construction basket 1, and their top ends are gathered and connected to a connecting ring 4, and the bottom end of the hoisting rope 5 is fixed through the connecting ring 4. The other end of the hoisting rope 5 is connected to the winch above the building through a pulley assembly. The pulley bracket 16 is fixed to the top of the building, and the pulley 6 is hingedly connected to the free end of the pulley bracket 16, allowing the hoisting rope 5 to smoothly slide thereon, thereby realizing the lifting operation of the construction basket 1.

[0036] Before each use, check all connection parts are fastened. Confirm the winch is working properly, the pulley assembly is not blocked, and the positioning walking wheel 13 can rotate freely. When it is necessary to lift the construction basket piece 1, start the winch to wind the hoisting rope 5, so that the construction basket piece 1 rises along the positioning vertical pole 7. In this process, the inclined support pole 11 and the positioning walking wheel 13 help maintain the balance of the construction basket piece 1 and prevent it from swinging. In order to lower the construction basket piece 1, the winch unwinds the hoisting rope 5, and the construction basket piece 1 slides down along the positioning vertical pole 7 under the action of gravity. The positioning walking wheel 13 continues to maintain contact with the wall, providing additional stability. If abnormal conditions occur during operation, such as sudden power failure or mechanical failure, due to the sliding connection design between the construction basket piece 1 and the positioning vertical pole 7, it can slowly descend under the action of gravity without external power until it stops completely, avoiding the risk of sudden falling. In addition, the rubber buffer ring wrapped around the positioning walking wheel 13 not only reduces noise but also plays a certain shock-absorbing role in emergency situations, protecting the safety of workers and equipment.

[0037] After use, the entire system should be regularly maintained, including lubricating the pulley piece 6, checking the wear of the hoisting rope 5, testing the performance of the winch, etc., to ensure that the equipment is in good condition for a long time.

[0038] The above is only the preferred embodiment of the present application, it should be understood that the present application is not limited to the form disclosed herein, should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be within the scope of the present application, by the above teaching or related art or knowledge to make changes. The changes and variations made by those skilled in the art do not deviate from the spirit and scope of the present application, and should be within the scope of protection of the claims attached to the present application.
