As shown in fig. 2, a protrusion 311 is fixed on the sidewall of the sliding barrel 31, and the protrusion 311 is provided with a sliding hole horizontally penetrating through which the steel wire rope 4 can penetrate. Meanwhile, a set of threaded holes is arranged on the boss 311, and each threaded hole is communicated with a corresponding sliding hole. When the steel wire rope sliding device is used specifically, the bolt 50 can be inserted into the threaded hole, and the steel wire rope 4 can be fixed on the sliding barrel 31 through the bolt 50. In order to improve the protection effect for the vehicle, the outer wall of the sliding cylinder 31 is further wrapped with a rubber sleeve 27, the thickness of the small rubber sleeve is preferably greater than 1cm, and the protruding portion 311 of the sliding cylinder 31 should be optimally arranged in the direction toward the outer side of the highway 1.
As a basic scheme of the invention, the protection structure of the invention is composed of two sets of identical winding drum devices 2 and a plurality of steel wire ropes 4, and three steel wire ropes 4 are adopted in the scheme. The two sets of reel devices 2 are fixed along the extending direction of the highway 1, and the distance between the two fixed sets of reel devices 2 is controlled between 30m and 50 m. When the winding drum device 2 is fixedly installed, firstly, a pit is dug in a roadbed of the highway 1, an embedded steel plate 25 is embedded in the pit, then, a ground leveling steel plate 24 is fixed through a foundation long bolt 23, and then, the installation of the steel winding drum is completed. After the steel reel is installed, the steel wire rope 4 can be tensioned by adopting a hand crank or a mode of installing the motor 100 on the steel reel, so that the steel wire rope 4 can be basically stretched between the two sets of reel devices, and then the locking shaft 51 is inserted, so that the steel reel 21 is locked, the steel reel 21 is prevented from rotating, and the steel wire rope 4 is kept in a straightening state under the action of gravity or the action of vehicle impact as far as possible. For the protection cover 22, the guide holes 221 on the protection cover 22 are used for positioning the steel wire ropes 4, and meanwhile, the steel wire ropes 4 can respectively correspond to the grooves on the steel reel through the guide holes 221, which also enables the three steel wire ropes 4 arranged up and down to be smoothly wound on the steel reel. Meanwhile, the rotating ring 26 arranged on the protective cover 22 limits the upper end of the steel winding drum, the ground leveling steel plate 24 limits the lower end of the steel winding drum, and the protective cover 22 and the steel winding drum are mutually matched to be more favorable for fixing the steel winding drum.
The steel wire rope 4 can be wound on the steel winding drum after the winding drum device 2 is installed, or can be directly wound on the steel winding drum. After the three steel wire ropes 4 are installed, the protection structure consisting of the two sets of winding drum devices 2 and the three steel wire ropes 4 starts to play a role, and the most basic and preliminary temporary safety protection system for the highway 1 is formed. The invention also adds a positioning component which is realized by matching the sliding barrel 31 and the positioning rod 32 when positioning the component 3. Through the lug boss 311 arranged on the sliding barrel 31, after the steel wire rope 4 passes through the lug boss 311 horizontally, the lower end of the sliding barrel 31 is in contact with the road surface of the highway 1, and the sliding barrel 31 and the steel wire rope 4 are supported by the road surface, so that the steel wire rope 4 positioned in the middle of the two sets of winding drum devices 2 can be prevented from falling downwards under the action of self gravity. The positioning rod 32 is additionally arranged on the sliding barrel 31, when the positioning rod 32 is used, the lower end of the positioning rod 32 is inserted into a roadbed of the highway 1, the positioning component 3 formed by the positioning rod 32 and the sliding barrel 31 can further limit and lock the trend of the steel wire rope 4, and particularly when the positioning component 3 is applied to a curve of the highway 1, the trend of the steel wire rope 4 can be limited by the positioning component 3, so that the steel wire rope 4 can be flush with the road edge of the curve of the highway 1. The bolt 50 fixes the wire rope 4 to the slipping cylinder 31, preventing the wire rope 4 from moving under the action of gravity or a vehicle impact. The outer wall of the sliding barrel 31 is wrapped by the rubber sleeve 27, and the shell of an out-of-control vehicle is in contact with the rubber sleeve 27, so that the friction effect of the sliding barrel 31 on the vehicle can be further reduced, and the damage degree of the positioning assembly 3 on the vehicle is reduced.
In the invention, the temporary protection system at the adjacent side of the road 1 is formed by two sets of winding drum devices and at least three steel wire ropes 4, so that the temporary protection system is convenient to observe, and simultaneously blocks out-of-control vehicles by using the steel wire ropes 4, and integrates warning and physical protection. Meanwhile, in the scheme, the steel wire rope 4 can be fixed on the sliding barrel 31 by using the bolt 50, the steel wire rope 4 is prevented from moving relative to the sliding barrel 31 after being impacted, the sliding barrel 31 is fixed on the road surface of the highway 1 through the positioning rod 32, so that the impact force of a vehicle is transmitted to the road surface of the highway 1 through the steel wire rope 4, the sliding barrel 31 and the positioning rod 32, the protection is effectively realized, and the sliding barrel 31 and the positioning rod 32 are organically cooperated with the steel wire rope 4, the steel drum 21 and other components to jointly realize the road surface protection. And, two sets of reel devices of this structure can reuse, can demolish after the construction is accomplished, practices thrift engineering measure expense, and is very suitable for being applied to present highway 1 interim safety protection. By additionally arranging the positioning component 3 and the rubber sleeve 27, the protective structure is not only suitable for straight sections of the highway 1, but also suitable for bent sections of the highway 1, and the elasticity of rubber is utilized to protect out-of-control vehicles, so that the economic loss of the out-of-control vehicles is further reduced. The invention also provides two different operation modes of the motor and the hand crank aiming at the steel winding drum, which are beneficial for construction personnel to select according to different actual conditions and further expand the application range of the protective structure.
The present invention is not limited to the above-described preferred embodiments, but includes all modifications, equivalents, and improvements within the spirit and scope of the present invention.
