Description

Technical Field

[0001] This utility model relates to the field of safety rope locking technology, and in particular to a safety rope locking device for preventing falls during high-altitude operations. Background Technology

[0002] High-altitude operations, such as building construction, bridge maintenance, and wind power equipment installation and repair, are characterized by complex and highly dangerous working environments, which place extremely high demands on the safety protection of workers. In these working environments, workers usually need to rely on equipment such as safety ropes and fall arrest devices to prevent accidental falls.

[0003] Traditional high-altitude work fall protection safety rope locking devices suffer from reduced rotation efficiency due to friction between bearing components during prolonged use. This also affects the operator's ability to adjust the length of the safety rope, further compromising the rotation efficiency of the wheel. Therefore, those skilled in the art have developed a high-altitude work fall protection safety rope locking device to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-altitude operation fall prevention safety rope locking device. This device uses a lubrication system to lubricate the inner ring, rollers, and outer ring, thereby improving the rotation efficiency of the wheel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-altitude operation fall prevention safety rope locking device, comprising a housing and a sealing cover, wherein the sealing cover is disposed at the center of the front end face of the housing, the center of the upper end face of the housing is provided with a rope inlet, the center of the lower end face of the housing is provided with a rope outlet, a rotating wheel is provided on both sides of the center of the interior of the housing, a support column is provided at the center of the front and rear end faces of the two rotating wheels, a slider is provided at the end of the four support columns, a groove is provided at the center of the rear inner wall of the housing and the rear end face of the sealing cover, the four sliders are respectively sleeved and slidably connected with the two grooves, and a lubrication device is provided at the center of one side of the four support columns;

[0006] The lubrication device includes an oil injection nozzle, a conveying assembly, and a bearing assembly. The oil injection nozzle is located at the center of one side of the support column, the conveying assembly is located at the input end of the oil injection nozzle, and the bearing assembly is located at the outer end of the support column.

[0007] The conveying assembly includes a flow channel, which is located at the inlet of the oil nozzle. An oil storage tank is provided at the upper end of the center of the support column. The outlet of the flow channel passes through the oil storage tank and leads to the inside of the oil storage tank. A one-way valve is provided at one end of the center of the inside of the oil storage tank.

[0008] The above technical solution involves injecting lubricating oil into the flow channel through an oil nozzle, and then adjusting the angle of the equipment by the operator to ensure that the lubricating oil flows into the oil storage tank through the flow channel. Finally, a one-way valve prevents the lubricating oil from flowing back.

[0009] Furthermore, the bearing assembly includes an inner ring, which is sleeved on one end of the outer side of the support column. Multiple rollers are arranged in a circular pattern on the outer side of the inner ring. An outer ring is sleeved at the center of the outer side of the multiple rollers. The outer ring is fixedly connected to the wheel. Multiple oil outlet holes are arranged in a front-to-back pattern on one side of the outer side of the inner ring. The multiple oil outlet holes pass through the outer ring and the support column in sequence and lead to the inner side wall of the oil storage tank.

[0010] Through the above technical solution, lubricating oil is delivered from the oil reservoir to the inner ring and rollers through the oil outlet, which satisfies the lubrication of the inner ring, rollers and outer ring, reduces their friction and wear, realizes the smooth rotation of the impeller, avoids the impact of long time on the rotation efficiency of the impeller, and thus improves the rotation efficiency of the impeller.

[0011] Furthermore, the outer center of the two rotating wheels is provided with a plurality of teeth arranged in a circular pattern near the front and rear, and the outer center of the two rotating wheels is provided with an annular groove. The rear inner wall of the outer shell and the rear end face of the sealing cover are provided with racks. The two racks are respectively engaged with the plurality of teeth. The safety rope body is provided in the center of the inner shell. The safety rope body is respectively wound and connected to the two rotating wheels.

[0012] The above technical solution involves the safety rope entering from one side of the spool, winding around the spool through the annular groove, and then exiting from the other side. As the spool rotates, the safety rope is either wound or released, thus allowing the operator to adjust the length of the safety rope. Furthermore, the meshing between the teeth and the rack allows for rotational locking of the spool, thereby locking the safety rope.

[0013] Furthermore, an adjustment structure is provided at the center of the upper end face of the two rear support columns and the upper end face of the two front support columns. The adjustment structure includes two support blocks, which are respectively set on the upper end face of the two support columns. A fixed rod is provided at the upper end of the center of one side of the support block, and a support rod is provided at the upper end of the center of the other side of the support block. The fixed rod passes through the support rod and extends into the interior of the support rod, and is slidably connected to the support rod. A spring is provided at the center of one inner side wall of the support rod, and a stop is provided at the end of the fixed rod. The stop is slidably connected to the support rod and fixedly connected to the end of the spring.

[0014] Through the above technical solution, when the main body of the safety rope is subjected to a large external force, the support rod and the fixed rod move under the force, which drives the two rotating wheels to move towards the center. This satisfies the meshing between the teeth and the rack, thus achieving the rotational locking of the rotating wheels and locking the main body of the safety rope. When the main body of the safety rope is not subjected to an external force, the compression spring is released, which satisfies the requirement to drive the rotating wheels back to their original position, so as not to affect normal use.

[0015] Furthermore, a clamping device is provided at the upper center of the inner surface of the outer shell. The clamping device includes two first rotating shafts, which are respectively located at the upper center of the two inner side walls of the outer shell. A clamping block is fixedly connected to the outer side of each of the two first rotating shafts. A second rotating shaft is provided at the lower center of one side of each of the two clamping blocks. An electric telescopic rod is provided at the upper center of each of the two inner side walls of the outer shell. The output ends of the two electric telescopic rods are fixedly connected to the two second rotating shafts respectively.

[0016] Through the above technical solution, the electric telescopic rod begins to extend, and the extension movement of the electric telescopic rod is transmitted to the clamping block through the second rotating shaft, causing the clamping block to rotate around the first rotating shaft and clamp the safety rope inward, thus satisfying the secondary locking of the safety rope body and improving its safety.

[0017] Furthermore, the two ends of the two first rotating shafts are respectively supported by a support plate and are rotatably connected to the support plate; the two ends of the two second rotating shafts are respectively supported by a support plate and are rotatably connected to the support plate.

[0018] Through the above technical solution, the rotation of the first and second rotating shafts enables the clamping of the clamping block and the smooth extension and retraction of the electric telescopic rod.

[0031] Reference Figure 1-6This utility model provides an embodiment of a high-altitude operation fall prevention safety rope locking device, comprising a housing 1 and a sealing cover 2. The sealing cover 2 is located at the center of the front end face of the housing 1. The center of the upper end face of the housing 1 is provided with a rope inlet 3, and the center of the lower end face of the housing 1 is provided with a rope outlet 4.

[0035] The two ends of the two first rotating shafts 1501 are supported by the support plate and are rotatably connected to the support plate. The two ends of the two second rotating shafts 1503 are supported by the support plate and are rotatably connected to the support plate. The rotation of the first rotating shafts 1501 and the second rotating shafts 1503 enables them to drive the clamping block 1502 to clamp and the electric telescopic rod 1504 to extend and retract smoothly.

[0036] like Figure 6As shown, the lubrication device 9 includes an oil injection nozzle 901, a conveying assembly, and a bearing assembly. The oil injection nozzle 901 is located at the center of one side of the support column 6. The conveying assembly is located at the input end of the oil injection nozzle 901. The bearing assembly is located at the outer end of the support column 6. The conveying assembly includes a flow channel 902, which is located at the input end of the oil injection nozzle 901. An oil storage tank 903 is provided at the upper end of the center inside the support column 6. The output end of the flow channel 902 passes through the oil storage tank 903 and leads to the interior of the oil storage tank 903. A one-way valve 904 is provided at one end of the center inside the flow channel 902. Lubricating oil is injected into the flow channel 902 through the oil injection nozzle 901.

The one-way valve 904 prevents the lubricating oil from flowing back.

[0037] The bearing assembly includes an inner ring 905, which is fitted onto one end of the outer side of the support column 6. Multiple rollers 906 are arranged in a circular pattern on the outer side of the inner ring 905. An outer ring 907 is fitted around the center of the outer side of the multiple rollers 906. The outer ring 907 is fixedly connected to the roller 5. Multiple oil outlet holes 908 are arranged in a front-to-back pattern on one side of the outer side of the inner ring 905. The multiple oil outlet holes 908 pass through the outer ring 907 and the support column 6 sequentially, leading to an inner wall of the oil reservoir 903. Lubricating oil is transported from the oil reservoir 903 through the oil outlet holes 908 to the space between the inner ring 905 and the rollers 906, thus satisfying the lubrication needs of the inner ring 905, rollers 906, and outer ring 907, reducing friction and wear, achieving smooth rotation of the roller 5, and preventing prolonged wear from affecting the rotational efficiency of the roller 5, thereby improving the rotational efficiency of the roller 5.

[0038] Working principle: When using the safety rope locking device for high-altitude operations, the safety rope body 14 enters the housing 1 through the rope inlet 3 and exits through the rope outlet 4. It then enters again through one side of the rotating wheel 5, winds around the rotating wheel 5 through the annular groove 11, and exits from the other side. As the rotating wheel 5 rotates, the safety rope body 14 is either wound or released, allowing for length adjustment of the safety rope body 14 for the operator. Lubricating oil is injected into the flow channel 902 through the oil nozzle 901, and then transported from the oil reservoir 903 through the oil outlet 908 to the area between the inner ring 905 and the roller 906. This lubrication of the inner ring 905, roller 906, and outer ring 907 reduces friction and wear, ensuring smooth rotation of the rotating wheel 5 and preventing prolonged use that could affect its rotational efficiency, thus improving the overall rotational efficiency of the rotating wheel 5.

[0039] When the safety rope body 14 is subjected to a large external force, it can drive the two rotating wheels 5 to move towards the center, and satisfy the meshing between the teeth 10 and the rack 13, thus satisfying the rotational locking of the rotating wheels 5 and locking the safety rope body 14. Then, through the operator's control of the electric telescopic rod 1504, the electric telescopic rod 1504 begins to extend. The extension movement of the electric telescopic rod 1504 is transmitted through the second rotating shaft 1503 to the clamping block 1502, causing the clamping block 1502 to rotate around the first rotating shaft 1501 and clamp the safety rope inward, thus satisfying the secondary locking of the safety rope body 14 and improving its safety.

[0040] When the safety rope body 14 is not subjected to external force, the compression spring 1204 is released, which satisfies the requirement to drive the wheel 5 to return to its original position, so as not to affect normal use.

[0041] 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.
