Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction machinery, in particular to a detachable lifeline fixing device. Background Art
[0002] In the construction of building exterior walls, high-altitude construction work is inevitably required. Lifelines need to be set up on the scaffolding for high-altitude construction work to prevent construction workers from falling and causing life and property safety problems, and to effectively protect the personal safety of workers.
[0003] In traditional technology, steel ropes and rope clamps are usually used as lifelines. The steel ropes are not hung in place, the setting procedures are cumbersome, and the use efficiency is low. Therefore, various lifeline fixing devices are also designed in the prior art to simplify the setting of the lifeline. For example, the patent document with application number 201920401316.X discloses a device for fixing the lifeline of a steel pipe scaffold, including a support rod, a main rope body and a bridge hanger. The outer surface of the support rod is equipped with fixing fasteners at both ends, and a rope tightener is provided on the left side of the fixing fasteners at both ends. A safety buckle is arranged on the left side of the rope tightener, and an anti-drop rope is connected to the bottom of the safety buckle. An intermediate node fastener is fixed on the left side of the main rope body, a card block is connected to the right side of the bridge hanger, and a positioning groove is provided inside the intermediate node fastener.
[0004] Although the above patent utilizes its structure to simplify the lifeline setting procedure, the connection method between the steel rope and the fixed fastener is a method of fixing the steel rope after bending it. The commonly used fixed connection is to squeeze and fix the bent steel rope with a bolt rope buckle. Although three bolt rope buckles are used, when workers are working at high altitudes, heavy tools and equipment fall down and hit the lifeline, or cause the lifeline to slide at the rope buckle position, thereby causing the edge of the lifeline to loosen and collapse, making it impossible to ensure the safety of the workers. Utility Model Content
[0005] The purpose of the utility model is to provide a detachable lifeline fixing device to solve the technical problem in the prior art mentioned above that the lifeline slides at the rope buckle position due to the fall of a large mass object on the lifeline, posing a safety hazard and failing to provide safety protection.
[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a detachable lifeline fixing device, including a fixing fastener connected to a scaffolding vertical rod, a steel rope bent and fixed on the fixing fastener, and a bolt rope buckle for fixing the steel rope, the fixing fastener is provided with an ear plate, the ear plate is provided with a fixing hole, the steel rope is bent through the fixing hole, a number of the bolt rope buckles are equidistantly arranged, and an anti-slip sleeve is provided between two adjacent bolt rope buckles and on the bent steel rope, one end of the anti-slip sleeve is a complete structure, and the other end is provided with an adjustment gap that can shrink the diameter of the anti-slip sleeve, and a threaded head and a clamping bolt that can close the adjustment gap, and an anti-protrusion anti-slip clamp that gradually shrinks the inner diameter of the anti-slip sleeve is provided in the anti-slip sleeve.
[0007] The beneficial effects of this embodiment are:
[0008] 1. Compared with the prior art, when the present application is in use, a bolt rope buckle is used to fix the bent steel rope head and the tightened steel rope, and then when the steel rope head passes through the inner cavity of the anti-slip sleeve, the diameter of the anti-protrusion anti-slip clamp set in the inner cavity of the anti-slip sleeve of the present application gradually decreases; therefore, the steel rope head first enters from the end with a larger diameter of the anti-protrusion anti-slip clamp and comes out from the end with a smaller diameter, so the steel rope head can easily pass through the anti-slip sleeve. After the steel rope head passes through, a clamping nut is used to close the adjustment gap of the anti-slip sleeve, the diameter of the anti-slip sleeve is reduced, and the anti-protrusion anti-slip clamp is clamped on the steel rope head. When the steel rope slides, the anti-protrusion anti-slip clamp clamps the steel rope head while resisting the bolt rope buckle, providing greater resistance, making it difficult for the steel rope to slide.
[0009] Furthermore, the anti-slip clamp is a contraction opening with an obtuse triangle cross section. The obtuse triangle makes the contact angle between the acute angle edge of the anti-slip clamp and the steel rope an inclined acute angle, so that after the steel rope is deformed, a seam resistance structure is formed at the lowest point of the deformation when the steel rope slides, and the anti-slip effect is good.
[0010] Furthermore, the anti-slip clamp includes a welding pad with a circular cross section, and the welding pad is provided with a circle of thorns with a gradually decreasing diameter. The thorns can be inserted into the gaps of the surface wires of the steel rope to provide better resistance.
[0011] Furthermore, the fixing fastener is a structure of two semicircular rings, one end of which is provided with a movable shaft, the fixing fastener is connected by the movable shaft to form a whole that can rotate around the movable shaft, and the other end is provided with a fixing bolt. This structure is easy to disassemble and install, and is convenient for repeated use.
[0012] Furthermore, a tensioning device is provided at a position of the steel rope near the fixing fastener, which ensures that the steel rope is tightened and provides reliable protection.
[0013] Further, the ear plates are equidistantly arranged on the circumference of the fixing fastener, and the four ear plates are arranged so that when the lifeline is set up, one of the ear plates can be used to complete the connection and fixation of the lifeline without adjusting the angle of the fixing fastener.

[0020] The following is further described in detail through specific implementation methods:
[0021] The figure marks in the drawings of the specification include: scaffolding vertical pole 1, steel rope 2, steel rope head 21, bolt rope buckle 3, fixing fastener 4, ear plate 41, fixing hole 411, movable rotating shaft 42, fixing bolt 43, anti-slip sleeve 5, adjustment gap 51, clamping edge 52, threaded head 53, clamping bolt 54, anti-slip clamp 55, anti-slip spur 56, welding pad 561, spur head 562, tensioning device 6.

[0023] Example 1
[0024] Example 1 is as shown in the attached Figures 1 to 3 , Figure 6As shown: a detachable lifeline fixing device includes a fixing fastener 4 connected to a scaffolding vertical rod 1. In the prior art, scaffolding is usually erected using a cross fastener. Therefore, a fixing fastener 4 is designed in this application. Compared with the cross fastener, the fixing fastener 4 is mainly a cross fastener with only one ring. In this way, the fixing fastener 4 of this application can be easily fixed to any scaffolding.
[0025] Fixing fastener 4 Figure 6 As shown, its structure is divided into two parts, both of which are semi-circular structures, one end of which is rotatably connected by a movable shaft 42, and the other end protrudes outside the circumference, and is provided with a fixing bolt 43 that can close the two semi-circular rings. Therefore, the two semi-circular rings of the fixing fastener 4 can rotate around the movable shaft 42, and the nut on the fixing bolt can be tightened at the other end to close it into a complete ring.
[0026] Four ear plates 41 are equidistantly arranged on the circumference of the fixing fastener 4, and a penetrating fixing hole 411 is opened in the middle of the ear plate 41. The inner surface of the fixing block 411 is smooth without any edges. When in use, the semicircular ring of the fixing member 4 is opened, and after being buckled on the scaffolding vertical rod 1, the nut on the fixing bolt is tightened to close the fixing fastener, thereby fixing the fixing fastener 4 to the scaffolding vertical rod 1.
[0027] After the fixing fastener 4 is fixed to the scaffolding vertical rod 1, the steel rope 2 is passed through the fixing block 411 on the ear plate 41 and then bent. The steel rope head 21 of the bent part is reversely overlapped with the steel rope and fixed with the bolt rope buckle 3. After both ends of the steel rope 2 are fixed to the fixing fastener 4 in this way, the steel rope is tensioned using the tensioning device 6 on the steel rope 2 (such as a basket bolt, etc. as the prior art). After tensioning, the steel rope head 21 is overlapped with the steel rope 2 again and fixed with the bolt rope buckle 3. After fixing with no less than two bolt rope buckles 3, the steel rope head 2 is passed through the anti-slip sleeve 5, and the anti-slip sleeve 5 is fixed on the steel rope head 21.
[0028] Anti-slip sleeve 5 Figure 2 , Figure 3 As shown, from the external structure, one end is a complete sleeve structure, and the other end is penetrated by a horizontal adjustment slit 51. Therefore, force can be applied to the end penetrated by the adjustment slit 51 to close the adjustment slit 51, thereby changing the diameter of the anti-slip sleeve 5. A thread is provided on the outer periphery of the end penetrated by the adjustment slit 51, which is a thread head 53. The non-threaded part of the thread head 53 in the direction of the center of the sleeve is separated from the threaded part by a clamping edge 52. The thread head 53 is provided with a clamping bolt 54 that cooperates with it. The inner cavity of the anti-slip sleeve 5 is a circular through-channel for the steel rope head 21 to pass through. An anti-protrusion anti-slip clamp 55 that is integrated with the anti-slip sleeve 5 is provided at the center of the inner cavity of the anti-slip sleeve 5. The cross-section of the anti-protrusion anti-slip sleeve 55 is as shown in FIG. Figure 3The obtuse trapezoid is shown, which reduces the inner diameter of the anti-skid sleeve 5. When in use, the steel rope head 21 is passed through the anti-skid sleeve 5 and the anti-skid clamp 55 of the inner cavity. Since the adjustment slot 51 is in an open state when the steel rope head 21 passes through the anti-skid clamp 55, the inner diameter of the anti-skid clamp 55 is larger than the diameter of the steel rope head 21. After the steel rope head 21 passes through, the clamping bolt 54 is sleeved on the threaded head 53, and the clamping bolt 54 is tightened, so that the adjustment slot 51 is closed, the inner diameter of the anti-skid clamp 55 is reduced, and the edge contacting the steel rope head 21 clamps the steel rope, causing it to deform, thereby preventing the steel rope 2 from sliding.
[0029] After the anti-skid sleeve 5 is installed on the steel rope head 21, the portion of the steel rope head 21 passing through the anti-skid sleeve 5 is fixed to the steel rope 2 using the bolt rope buckle 3, since the anti-skid sleeve 5 can swing at will. After the lifeline is erected, the worker's safety rope buckle can be sleeved on the lifeline and can slide on the lifeline. When the worker falls accidentally, the worker's safety rope can be connected to the lifeline, so the worker can be suspended to prevent the worker from falling.
[0030] Example 2
[0031] Example 2 Figure 1 , Figure 2 , Figure 4-Figure 6 As shown, the difference between it and Example 1 is as follows Figure 4 , Figure 5 As shown, the anti-skid spur 56 replaces the anti-skid clamp 55 in Example 1. The anti-skid spur is divided into a welding pad 561 and a spur head 562. The purpose of the welding pad 561 is mainly because the structure of the anti-skid spur 56 is relatively complex. After the external processing, it is placed in the inner cavity of the anti-skid sleeve 5 for welding. The size of the welding pad 561 is slightly larger than the inner cavity diameter of the anti-skid sleeve 5. Tools are required to knock the anti-skid spur 56 into the anti-skid sleeve 5 for welding. The spur head 562 and the welding pad 561 are integrally processed as a whole. The structure is an elongated cone, and the end of the spur head 562 shrinks toward the center. After the clamping bolt 54 is used to close the adjustment gap 51, it will be stuck in the surface of the steel rope head 21, thereby increasing the resistance of the steel rope 2 to sliding.
[0032] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
