Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide a safety protection device for exterior wall construction operations, mainly used to ensure the safety of workers during the construction of exterior walls of high-rise buildings. It effectively solves the safety hazards existing in high-altitude operations due to the lack of reliable, movable, and non-destructive safety belt fixing points. This invention provides a safety protection device for exterior wall construction operations, which provides a stable attachment point for the safety rope through a telescopically adjustable support rod structure. In the event of a sudden fall accident, the top support components on both sides of the support rod instantly increase the friction with the foundation, thereby ensuring that the device can still be firmly attached to the wall in the critical state of the accident, preventing it from falling off, maximizing the safety of the workers, and providing time for subsequent emergency rescue.

[0020] like Figure 1 and 2As shown, this embodiment provides a safety protection device for exterior wall construction operations, including a support rod 2, a central sleeve 1, a top support assembly 3, and a tightening assembly 4. The adjacent ends of two support rods 2 are connected together through the central sleeve 1. The inner cavity of the support rod 2 is hollow, and the far end of the support rod 2 is provided with a top support assembly. In this embodiment, the top support assembly 3 includes a limiting sleeve 31, a traction sleeve 37, a connecting rod 36, and a top support block 34. Threads are provided on the outer wall of the far end of the support rod 2. Internal and external threads are machined on the limiting sleeve 31. The limiting sleeve 31 is threaded to the end of the support rod 2, and an adjusting sleeve 32 is threaded to the limiting sleeve 31 and the support rod 2. The adjusting sleeve 32 is threaded to the outside of the limiting sleeve 31, and the adjusting sleeve 32 is slidably fitted on the outside of the support rod. Thus, by turning the adjusting sleeve 32, the extension length of the limiting sleeve 31 at the end of the support rod 2 can be adjusted, thereby realizing the adjustment of the horizontal extension length of the protection device to adapt to foundations with different spacing.

[0021] A limiting platform 33 is also provided at the end of the limiting sleeve 31 away from the support rod 2, and hinge seats are symmetrically provided on the limiting platform 33. Figure 3 and 4 As shown, the traction sleeve 37 is slidably fitted inside the limiting sleeve 31, and a stop is provided at one end of the traction sleeve 37 away from the limiting sleeve 31. A support spring 35 is provided between the stop of the traction sleeve 37 and the limiting platform 33 of the limiting sleeve 31. Hinges are also symmetrically fixed on the side wall of the traction sleeve 37 for mounting the connecting rod 36.

[0022] like Figure 4 As shown, the outer end of the traction sleeve 37 is provided with an adsorption component 5. In this embodiment, the adsorption component 5 includes a suction cup seat 51, a screw 52, ​​and a suction cup 53. The suction cup seat 51 is rotatably fitted onto the outer end of the traction sleeve 37, and the screw 52 is rotatably mounted on the suction cup 53. The screw 52 is threaded into the suction cup seat 51, and rotating the suction cup seat 51 can adjust the extension length of the suction cup 53. The inner end of the traction sleeve 37 is a solid structure, and a force transmission rope 38 is fixed on its side wall. The force transmission rope 38 passes through the support rod 2 and can be led outward from the middle of the central sleeve 1.

[0023] like Figure 3As shown, at least two groups of connecting rods 36 are located outside the support rod 2, and in this embodiment, two groups of connecting rods 36 are respectively located on the upper and lower sides of the suction cup 53, each group of connecting rods 36 includes a driving rod 361 and a swing rod 362, one end of the swing rod 362 is hinged to the limiting table 33 at the end of the limiting sleeve 31, and the other end of the swing rod 362 is fixedly connected to the top support block 34, the top support block 34 and the suction cup 53 act on the same base; one end of the swing rod 362 is hinged to the driving rod 361, and the other end thereof is hinged to the hinge seat of the traction sleeve 37. In this embodiment, the top support block 34 includes a gripping layer 341 and a friction layer 342, wherein the gripping layer 341 is obliquely arranged above the friction layer 342, and in the initial state, the friction layer 342 of the top support block 34 is pressed on the base, and after the top support block 34 swings, the gripping layer 341 can also be pressed tightly on the building base.

[0024] The arrangement of the top support assembly in this embodiment is that when the falling pulling force rope 38 is pulled, the traction sleeve 37 is forced to move linearly towards the limiting sleeve 31, at the same time, the upper and lower driving rods 361 are brought to shrink towards each other, the movement of the driving rod 361 forces the swing rod 362 hinged at the other end thereof to produce a rotary motion, so as to convert the axial tension of the traction sleeve 37 into a strong pressing force of the top support block 34 on the building base, and then amplify the smaller axial input force into a larger normal pressing force of the top support block 34 on the wall.

[0025] Further, in the initial normal state, the friction layer 342 of the top support block 34 is tightly pressed on the building base, and the entire device provides a working fixed point for the safety rope 6; when the top support block is swung by the swing rod after being triggered by the falling, the inclined gripping layer 341 is strongly pressed against the base surface, thereby significantly increasing the normal pressure of the contact surface of the top support block 34 and the building base, and the multiplication of the normal pressure directly leads to an instantaneous sharp increase in the maximum static friction, at the same time, the inclined angle design of the gripping layer makes the direction of the friction force not only resist the tendency of the device to slide down along the wall, but also generate an inward force directed towards the wall, helping the device to bite the wall more firmly, and greatly enhancing the anti-pulling-off capability.

[0026] In addition, since the top support block 34 and the suction cup 53 act on the same base, at the moment of falling, the suction cup provides a negative pressure adsorption force, and the top support block provides a strong mechanical pressing force and friction resistance, the two of which work together to resist the tendency of the device to be pulled away from the wall, forming a double protection mechanism, improving the overall stability of the device in the stressed state, preventing it from loosening under continuous impact, thereby providing important fall interception protection for the workers, winning valuable time for subsequent rescue, and ensuring the safety of the workers.

[0027] As Figure 5 and 6As shown, the tightening assembly 4 in the embodiment includes a main elastic member 42, an auxiliary rope 41 and a fixed seat. The central sleeve 1 is connected between adjacent support rods 2. In the embodiment, ring seats 11 are arranged at intervals on the central sleeve 1. Guide seats 21 are arranged on the support rods 2 close to one end of the central sleeve 1. Connection holes 22 are formed in the guide seats 21. Rubber sleeves 12 are sleeved between the guide seats 21 of the support rods 2 and the ring seats 11 of the central sleeve 1.

[0028] Arc-shaped strip holes are formed in the central sleeve 1. The main elastic member 42 is arranged below the central sleeve 1 and corresponds to the strip holes of the central sleeve 1. The force transmission rope 38 is connected to the main elastic member 42 after being led out of the support rod 2. In a specific implementation structure, the main elastic member 42 in the embodiment includes an outer sleeve 421, a main connecting rope 425, a spring 422 and a T-shaped movable rod 424. The outer sleeve 421 is fixed outside the central sleeve 1 and communicates with the inner cavity of the central sleeve 1. The outer sleeve 421 is internally fixed with a limiting seat. The movable rod 424 is slidably sleeved in the limiting seat. The top of the movable rod 424 extends above the limiting seat and is fixedly connected with the output end of the force transmission rope 38. The spring 422 is fixed between the movable rod 424 and the limiting seat.

[0029] The fixed seat is located below the main elastic member 42. The free ends of the main connecting rope 425 and the auxiliary rope 41 are tied to the fixed seat. One end of the main connecting rope 425 is fixedly connected with the bottom of the movable rod 424. The output end of the main connecting rope 425 extends out of the outer sleeve 421 and is fixedly tied to the fixed seat. One end of the auxiliary rope 41 is fixedly tied in the connection hole 22. The other end of the auxiliary rope 41 is fixedly tied to the fixed seat. The bottom of the fixed seat is provided with a lifting ring 44. The safety rope 6 is tightly hooked on the lifting ring 44 through the anti-abrasion hot melt insulating gasket 7. The other end of the safety rope 6 is tied to the worker.

[0030] As shown, Figure 8 under the action of an external force, the safety rope 6 first transmits the external force to the main connecting rope. The main connecting rope transmits the external force to the force transmission rope 38 through the movable rod 424, so that the movable rod 424 slides outward along the limiting seat, and at the same time, the spring 422 is stretched. Then, the auxiliary rope 41 is pulled, and the auxiliary rope 41 is changed from a slack state to a tension state to disperse the stress and avoid stress concentration in the middle part of the central sleeve 1, so as to prevent the central sleeve 1 from being broken.

[0031] The safety rope 6 of the worker is tied to the hanging ring 44 of the fixed seat in this arrangement of the tightening assembly 4 in the embodiment, when a falling occurs, a huge impact force is first transmitted to the main connecting rope 425 through the safety rope 6, the main connecting rope pulls the movable rod, the movable rod 424 slides outward against the spring resistance, the spring is stretched, at this time, the movable rod 424 first acts as a rigid force transmission carrier, directly and efficiently guides the tension to the spring and the force transmission rope 38, and the deformation amount and the force of the spring are physically limited by the sliding stroke of the movable rod 424, so that even in the face of a huge impact force, the spring will not be stretched to the plastic deformation zone or the breaking point, effectively avoiding the risk of permanent failure of the spring 422 in the pure spring buffer system due to exceeding the elastic limit.

[0032] After the spring is stretched and the movable rod 424 moves a certain distance, the tension of the main connecting rope 425 on the fixed seat increases, and the auxiliary rope 41 is pulled tight from the relaxed state, the tension in the middle part of the center sleeve 1 is effectively shunted to the auxiliary ropes 41 on both sides, and the auxiliary ropes 41 are connected to the connecting holes 22 of the guide seats at the ends of the support rods, respectively, so that the load is not concentrated on a point in the middle part of the center sleeve, but is dispersed and transmitted to the support rod structures on both sides, effectively solving the problem of stress concentration, greatly improving the structural strength and stability of the entire device when bearing extreme tension, and preventing the center sleeve from breaking. The external load is finally borne by the movable rod and the auxiliary rope, and is dispersed to the support rod 2 structures on both sides of the center sleeve 1, thereby significantly reducing the stress level at the center position and improving the structural integrity and fatigue resistance of the entire device under extreme impact.

[0033] Further, as shown in Figure 7 The guide wheels 8 are fixed at intervals in the support rod 2, and the force transmission rope 38 is guided by the guide wheels 8, which can accurately constrain the movement of the force transmission rope 38 in the support rod 2, avoid wear or jamming caused by direct friction between the rope body and the pipe wall, reduce the resistance when the force transmission rope 38 moves, ensure that the traction force can be quickly and smoothly transmitted to the jacking assembly 3 during a fall, and also evenly distribute the tension of the force transmission rope 38 through point-by-point guidance to prevent local stress concentration and breakage, thereby ensuring the reliability of force transmission.

[0034] Working principle; the external wall construction safety protection device provided by the application is horizontally supported on a stable foundation such as a building window or two side walls by two side telescopic adjustable support rods in a normal working state, the suction cups at the ends of the support rods are pre-adjusted to adhere to the surface of the wall by screwing the suction cup seats to provide basic adsorption force; the jacking block is in the initial position, the friction layer at the bottom thereof is in contact with the surface of the foundation to provide regular friction force; the safety rope is hung through the hanging ring below the fixed seat, the worker ties the safety belt to the safety rope for work; at this time, the force transmission rope is in a relaxed state, the jacking spring is not compressed, and the auxiliary rope is also in a relaxed state, the entire device is stably attached to the wall and does not hinder the worker's movement and operation.

[0035] When a sudden falling accident occurs, the huge pulling force generated by the worker falling is transmitted to the fixed seat through the safety rope, and then the main connecting rope is suddenly pulled tight, the main connecting rope pulls the movable rod to slide in the outer sleeve, and the main spring is stretched to perform preliminary buffering. At the same time, the movement of the movable rod synchronously and rapidly pulls the two side traction sleeves to move towards the center sleeve direction through the force transmission rope; the traction sleeve compresses the supporting spring and drives the driving rod, the driving rod links the swing rod to make the supporting block quickly rotate towards the wall body; and then the grabbing layer of the supporting block is strongly pressed and wedged into the surface of the wall body, and the friction force and mechanical biting force several times larger than the initial state are generated instantaneously, so that the grabbing layer is tightly pressed on the building foundation, and the device is prevented from being pulled off.

[0036] While the main spring is stretched to absorb part of the impact energy, the movable rod slides to the end of the stroke; at this time, the pulling force of the main connecting rope on the fixed seat increases dramatically, and the auxiliary rope is tightened; after the auxiliary rope is tightened, the remaining huge impact load is effectively shunted from the middle part of the center sleeve to the two side supporting rods, which significantly reduces the stress concentration of the center sleeve and prevents it from breaking; under the synergistic action of the suction cup and the supporting block, the device is firmly adsorbed on the wall body under the falling impact, providing a reliable anchor point for stopping the worker from falling further and gaining time for rescue.

[0037] The outer wall construction operation safety protection device provided by the application is simple to manufacture, easy to use, safe and efficient, easy to assemble and carry, and can not only provide a stable and movable hanging point in a normal state, but also trigger the supporting block to increase the friction self-locking through pure mechanical linkage and use the spring buffering and auxiliary rope connection double-path load dispersion when a falling accident occurs, effectively ensuring the reliability and stability of the device as a whole, providing important falling interception protection for the operating personnel, and gaining valuable time for subsequent rescue.

[0038] The embodiments of the application described above do not constitute a limitation on the protection scope of the application, and the basic idea of the application is to realize self-adaptive safety enhancement in a stressed state through mechanical linkage, which can efficiently convert the impact load into the normal pressure between the supporting block and the wall body when an accident occurs, thereby sharply increasing the static friction force of the contact surface, forming a strong mechanical grabbing, and ensuring the safety of the worker. Any modification, equivalent replacement and improvement within the spirit and principles of the application shall be included in the protection scope of the claims of the application.
