The utility model provides a kind of cable reel damper, it is related to cable reel damper technical field, including cable rack, the front of cable rack is equipped with the cable reel of circular and symmetrical installation, and the back of cable reel extends to the inside installation damper body, further inside the installation rotating bearing of damper body, and inside rotating bearing extends and is equipped with the rotating shaft of the cable reel of installation, and in the end of rotating shaft away from rotating bearing and located the inside installation ball bearing of cable reel, the end of rotating shaft and away from ball bearing is equipped with support block in the periphery, and support roller is installed in the bottom of support block, the utility model is designed, the both ends of cable reel can be effectively supported, to effectively prevent its one end from gravity tilt and pry damper, cause damper damage.

The utility model belongs to the technical field of construction safety equipment, and particularly relates to a platform high-position anti-falling safety protection device which comprises a surrounding plate and four rotating plates, an anti-falling net is installed in the surrounding plate, four grooves are formed in the bottom of the surrounding plate, buffering assemblies are arranged on the four rotating plates, a baffle is installed at one end of the surrounding plate, and the other end of the surrounding plate is provided with an anti-falling net. A storage assembly is arranged on the surrounding plate; the buffering assembly comprises a supporting base, and two limiting rods are installed in the supporting base. The anti-falling safety protection at a high place can be carried out through the anti-falling net, and the supporting seat and the rotating plate can be conveniently stored in the groove through the arrangement of the storage assembly, so that the aim of conveniently carrying the coaming and the anti-falling net is achieved, the occupied space is reduced, and the flexibility is improved; and through the arrangement of the buffering assembly, buffering can be provided when the articles or the personnel fall, the phenomenon that the anti-falling net is damaged due to too large impact force is avoided, and the personnel safety and the service life of the device are guaranteed.

The utility model relates to the technical field of protective fences, and discloses a road protective fence with good buffer performance, which comprises a protective fence body, a plurality of first grooves are arranged on the inner wall of the protective fence body, protective rods are sleeved in the first grooves in a sliding manner, a sponge is fixedly sleeved in each protective rod, and a plurality of second grooves are arranged on the inner wall of the protective fence body. A first shock absorber is fixedly connected to one side of the protective rod, the end, away from the protective fence body, of the first shock absorber is fixedly installed in the protective fence body, and a protective plate is fixedly connected to one side of the protective rod. According to the device, the interior of the protection rod is filled with the sponge, the elasticity of the sponge can be utilized to absorb impact force in a deformation mode when the sponge is impacted, damage of the impact force to an object can be reduced instantly, the first groove and the sliding groove are utilized, and it is guaranteed that a certain buffering process is reserved for the protection rod; and meanwhile, under the action of the first shock absorber and the second shock absorber, the shock absorption and buffering effect of the protection rod is further improved.
