Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude construction safety, in particular to an H-shaped steel beam horizontal lifeline device. Background Art

[0002] As my country continues to complete urbanization, the construction field is increasingly developed, and various high-rise buildings are springing up. When building high-rise buildings, steel frame structures are generally used. Workers work on steel frames and their safety needs to be guaranteed. Therefore, safety hooks are generally used to buckle on the life ropes of the steel structures to ensure the safety of workers working at heights.

[0003] The existing life rope is generally manually wrapped around the various steel pipes of the steel structure in advance, and thus wrapped and stretched. However, in actual use, the tightness of various parts of the life rope is different. When a fall occurs at a loose part, an accident may occur. When a construction worker falls at a tightened part of the life rope, the fall of the construction worker is not cushioned, and the tightening of the safety rope connected to the hook may cause secondary injury to the worker by falling. Utility Model Content

[0004] In view of the defects existing in the prior art, the utility model provides an H-shaped steel beam horizontal lifeline device, which can solve the problem that the lifeline cannot buffer the construction workers when they accidentally fall, and achieve the effect of buffering the construction workers falling from high altitude and preventing the safety rope from causing secondary injuries when the construction workers fall.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A horizontal lifeline device for an H-shaped steel beam comprises a device body, which comprises two mounting seats arranged at intervals along the length direction of the H-shaped steel beam; a connecting line is arranged between the two mounting seats; buckles connected to the mounting seats are respectively arranged at both ends of the connecting line; a buffer mechanism is arranged at one end of the connecting line, the buffer mechanism comprises a mounting block connected to the buckle, a mounting groove is arranged in the mounting block, a telescopic rod connected to the connecting line is arranged in the mounting groove; a baffle is arranged at one end of the telescopic rod away from the connecting line; a spring is also arranged in the mounting groove, which is sleeved on the telescopic rod and pushes the baffle to keep the connecting line in a taut state.

[0007] With the utility model, construction workers hang the hook on the safety rope on the connecting line. When the construction workers accidentally fall from a height, the safety rope is tightened. At this time, the connecting line is pulled, and the connecting line drives the telescopic rod and the baffle to squeeze the spring, thereby slowing down the falling speed of the construction workers and preventing the safety rope from suddenly tightening and causing damage to the construction workers.

[0008] Preferably, first strip holes communicating with the mounting groove are provided at the side walls at both ends of the mounting block, and the two ends of the baffle extend into the first strip holes respectively.

[0009] With the utility model, when the telescopic rod drives the baffle to push the spring, the baffle slides in the first strip hole, thereby preventing the baffle from crushing the spring due to excessive pulling force of the telescopic rod.

[0010] Preferably, the mounting base includes a base plate, both ends of the base plate are provided with support plates arranged along the width direction of the base plate, the upper end of the support plate is provided with a sliding plate arranged along the length direction of the base plate; the upper end of the sliding plate is provided with a connecting column for snap connection; the side wall of the sliding plate located at the upper end of the support plate is provided with a second strip hole, and the second strip hole is provided with a first bolt that passes through the second strip hole and is embedded in the support plate.

[0011] With the utility model, when a construction worker falls, if the tension on the connecting wire is too large, the connecting wire will pull the connecting column and drive the sliding plate to move, thereby further cushioning the falling construction worker.

[0012] Preferably, a fixing structure is provided at both ends of the base plate, and the fixing structure includes vertical plates arranged at both ends of the base plate, and a horizontal plate extending toward the base plate is provided at the lower end of the vertical plate; a second threaded rod is provided at the side wall of the vertical plate, passing through the vertical plate and extending to the upper end surface of the vertical plate; a third threaded rod is provided at the lower end surface of the horizontal plate, passing through the horizontal plate and extending to the lower end surface of the base plate.

[0013] With the utility model, before work, construction workers need to stick the bottom plates of the two mounting seats on the H-shaped steel beam respectively, then pull the distance between the two mounting seats apart to tighten the connecting line, and then rotate the second threaded rod to make the second threaded rod extend above the bottom plate and press on the bottom plate, and then rotate the third threaded rod to make the third threaded rod press against the H-shaped steel beam, thereby fixing the mounting seat; thereby, it is more convenient for workers to fix the mounting seat.

[0014] Preferably, a protrusion for the first bolt to be embedded is provided on the upper end surface of the support plate.

[0015] With the utility model, when installing the sliding plate, the installer places the sliding plate on the supporting plate and then inserts the first bolt through the second strip hole into the protrusion, thereby conveniently fixing the sliding plate.

[0016] Preferably, the side walls at both ends of the sliding plate extend downward to clamp on both sides of the protrusion.

[0017] With the utility model, the sliding plate slides along the protrusion when being pulled, thereby preferably improving the stability of the sliding plate when moving. BRIEF DESCRIPTION OF THE DRAWINGS
