Description

Technical Field

[0001] This utility model relates to the technical field of safety equipment, and in particular to a safety rope attachment protection device for the traveling steel beam of lifting machinery. Background Technology

[0002] Cranes are frequently maintained and repaired. Maintenance personnel often walk on high steel beams, and there is nowhere to attach their safety belts, which can easily lead to falls from heights and poses a safety hazard.

[0003] Existing safety rope attachment protection devices, such as the movable safety rope attachment point protection device disclosed in utility model patent application number 202321266658.8, mainly include a steel pipe, a lower adjustable leg, an upper adjustable leg, and a safety belt attachment assembly. The upper and lower adjustable legs are installed at the top and bottom of the steel pipe, respectively. The safety belt attachment assembly is fixed to the outer wall of the steel pipe. The lower and upper inner walls of the steel pipe are respectively provided with lower and upper internal threads, which are in opposite directions. In use, by adjusting the lower and upper adjustable legs, the entire device can be supported between the upper and lower floor slabs. By hooking the safety rope onto the safety belt attachment assembly, it can protect construction workers from falling to the ground in the event of a collapse of the mobile platform.

[0004] However, most existing safety rope attachment protection devices are not suitable for the movement of steel beams on crane machinery, are difficult to install on steel beams, and are not convenient to move with maintenance personnel. They can easily get stuck and pull on maintenance personnel, which is very dangerous. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a safety rope attachment protection device for walking on the steel beam of crane machinery, which is not only suitable for maintenance personnel to walk on the steel beam of crane machinery, but also convenient to follow the movement of maintenance personnel and avoid the device getting stuck and pulling on the maintenance personnel.

[0006] This utility model discloses a safety rope attachment protection device for the traveling steel beam of crane machinery, including a steel beam; it also includes a moving mechanism, a fixing mechanism, and a winding mechanism. The moving mechanism is installed on the steel beam to facilitate the movement of the protection device with maintenance personnel. The fixing mechanism is installed on the moving mechanism and facilitates connection with the safety belt. The winding mechanism is installed on the moving mechanism and secures the safety rope. Maintenance personnel connect the safety belt buckle to the fixing mechanism and partially wind the safety rope around the winding mechanism, then tighten the winding mechanism. When moving for maintenance, the moving mechanism and the fixing mechanism move with the maintenance personnel, facilitating the movement of maintenance personnel on the crane steel beam.

[0007] Preferably, the steel beam includes a steel beam body, a guide rail, two sets of fixed seats, and a steel wire rope. The steel beam body is installed inside the factory building, and the bottom end of the guide rail is connected to the top end of the steel beam body. The guide rail has a sliding groove. Both sets of fixed seats are installed on the steel beam body, and the steel wire rope is installed between the two sets of fixed seats. The guide rail facilitates the sliding of the moving mechanism and prevents the moving mechanism from falling off the guide rail. The fixed seats facilitate the limiting of the fixed mechanism and improve the safety of the device.

[0008] Preferably, the moving mechanism includes a moving block, two sets of locking blocks, two sets of connecting shafts, and two sets of rollers. The moving block is slidably mounted on the guide rail. The moving block has two sets of limiting holes. Both sets of locking blocks are mounted on the moving block and engage with the guide rail. Both sets of connecting shafts are rotatably mounted on the moving block. The two sets of rollers are respectively mounted on the two sets of connecting shafts. By setting two sets of locking blocks, the moving block is prevented from falling off the guide rail. By setting two sets of connecting shafts and two sets of rollers, the moving block can move smoothly on the guide rail, avoiding jamming and improving the smoothness of the moving block's movement.

[0009] Preferably, the fixing mechanism includes a connecting plate, a guide wheel, two sets of wear-resistant washers, and a connecting buckle. The connecting plate is mounted on the moving block and has positioning holes. The guide wheel is rotatably mounted on the connecting plate. Both sets of wear-resistant washers are installed in the positioning holes of the connecting plate, and the connecting buckle is mounted on the connecting plate. Maintenance personnel fasten the hook of the safety rope to the connecting buckle, and the wire rope passes through the positioning holes of the connecting plate. By setting two sets of wear-resistant washers, hard friction between the wire rope and the connecting plate is avoided, reducing wear and extending service life. By setting the guide wheel, the smoothness of the connecting plate moving on the wire rope is improved.

[0010] Preferably, the guide wheel is selected with a V-shaped groove; selecting a guide wheel with a V-shaped groove can prevent jamming between the wire rope and the guide wheel, improve the guiding performance of the guide wheel, and facilitate maintenance personnel to move the device.

[0011] Preferably, the winding mechanism includes bolts, a top plate, and two sets of columns. The bolts are screwed to the top of the moving block, the top plate is rotatably mounted on the bolts, and the tops of the two sets of columns are connected to the bottom of the top plate. The maintenance personnel wrap the safety rope around the two sets of columns, and then tighten the bolts. The bolts spiral down, causing the top plate to descend. The top plate then causes the two sets of columns to descend and insert into the limiting holes of the moving block, preventing the safety rope from falling off.

[0012] Preferably, the two sets of uprights are also covered with rubber sleeves; by setting the rubber sleeves, not only can the friction between the uprights and the safety rope be increased, but the wear of the safety rope can also be reduced.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: maintenance personnel connect the safety belt buckle to the fixed mechanism and wrap the safety rope part around the winding mechanism, and then tighten the winding mechanism. When the maintenance personnel move, the moving mechanism and the fixed mechanism move with the maintenance personnel, which makes it convenient for the maintenance personnel to walk on the crane steel beam.
