[0002] At present, in pursuit of the beauty of the external structure of buildings, people have produced more unique and alternative buildings. This has brought unexpected consequences to the safety of construction units and construction workers engaged in the construction industry, and the safety situation is not optimistic.
[0003] Among them, high-altitude fall accidents have topped the list for many years, accounting for about 50% of the total number of accidents. Safety accidents have occurred frequently year after year. Therefore, during construction, a new type of portable horizontal mobile fall prevention device that is more stable, non-slip, convenient, easy to check, and easy to replace is needed to ensure the personal safety of workers working at heights or in the air.
[0004] In other words, in the prior art, construction workers perform more construction work on edges, in the air, and on exterior walls, and protective measures and devices cannot guarantee the safety of construction workers, especially peripheral construction. The cost of construction measures is also relatively increased, affecting the safety of construction workers and production progress. Utility Model Content

It can be moved freely in the horizontal direction without the personnel losing stability, and is simple to install and disassemble, making it convenient for personnel to change positions. In addition, it can be carried with construction personnel at any time, and when the operating personnel lose stability, the personal safety of the personnel can be guaranteed in a timely and effective manner.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A portable horizontal movement anti-falling device, comprising: a five-sided steel plate shell, and a flip-type steel plate connected to the five-sided steel plate shell through a steel hinge; a compression lock is provided at the free opening and closing position of the flip-type steel plate and the five-sided steel plate shell;
[0008] A pair of fixed steel track pulleys are arranged on the inner side of the five-sided steel plate shell, and steel plate support members are arranged at intervals below the fixed steel track pulleys, and a non-slip, shock-proof and wear-resistant rubber pad is arranged on the side of the steel plate support member adjacent to the fixed steel track pulley; a pair of limiting screws are arranged on the other side end surface of the steel plate support member and the five-sided steel plate shell, and a connecting piece is arranged on one end surface of the steel plate support member located at the limiting screw, and the connecting piece is movably connected with a V-shaped steel plate connecting piece, and the other end of the V-shaped steel plate connecting piece is connected to a straight-shaped connecting steel piece with holes; a spring is arranged in the area of the five-sided steel plate shell away from the fixed steel track pulley, and the other end of the spring is connected to one end of the V-shaped steel plate connecting piece adjacent to the connecting piece;
[0009] The steel wire rope passes through the gap space between the fixed steel track pulley and the steel plate support; at the same time, the steel wire rope is connected between two safety rope hanging mechanisms, and the safety rope hanging mechanisms are fixedly installed at both ends of the wall.
[0010] Among them, after the flip-type steel plate is opened, the gap space between the fixed steel track pulley and the steel plate support can be completely exposed.
[0011] Specifically, the connecting piece and the V-shaped steel plate connecting piece, as well as the V-shaped steel plate connecting piece and the I-shaped connecting steel piece with holes are movably connected via first connecting bolts.

[0014] Specifically, the gap space between the fixed steel track pulley and the steel plate support is larger than the diameter of the steel wire rope.
[0015] Furthermore, the five-sided steel plate shell is matrix-distributed with a plurality of shell fixing connection bolts.
[0016] Compared with the prior art, the portable horizontal moving anti-falling device described in the utility model has the following advantages:
[0017] In the portable horizontal moving anti-falling device provided by the utility model, the steel wire rope is not easy to deviate under the condition of being stressed. After being stressed, the steel wire rope can be well squeezed in the upper fixed steel track pulley, so that the locked steel wire rope can move horizontally and left and right and prevent falling. When in use, the locking steel wire rope passes horizontally through the horizontal anti-falling device, and after the safety rope is hung on the I-shaped connecting steel sheet with holes and is subjected to downward force, the internal V-shaped steel plate connecting sheet moves upward and the upper fixed steel track is squeezed downward, so that the steel wire rope can be pressed tightly in the steel track groove and tightly pressed between the anti-skid and wear-resistant rubber pad, and at the same time the external pressing lock is buckled, so that the steel wire rope is firmly locked inside the device. From this, it can be seen that the portable horizontally movable fall prevention device provided by the utility model, the construction workers fix the hook on the safety rope on the portable horizontally movable fall prevention device, which can not only quickly and stably fix the safety rope, but also make the portable horizontally movable fall prevention device vertically locked under force, which is convenient to install during the construction process and easier to disassemble after completion; in addition, the use of high-strength engineering materials can expand the force range of this portable horizontally movable fall prevention device to 350kg, which ensures that the safety rope has sufficient bearing capacity and buffering force when it is in working state while being stressed under the weight of the construction workers, thereby effectively ensuring the safety of the construction workers; in other words, the portable horizontally movable fall prevention device provided by the utility model is mainly fixed in its original position by squeezing the anti-slip and wear-resistant rubber pad with the track pulley, thereby greatly reducing the risk factor of construction workers during edge operations or high-altitude operations.

After being stressed, the steel wire rope 15 can be well squeezed into the upper fixed steel track pulley 6, so that the locked steel wire rope 15 moves horizontally and left and right and prevents falling. When in use, the locked steel wire rope 15 passes horizontally through the horizontal anti-falling device, and after the safety rope is hung on the I-shaped holed connecting steel sheet 13 and subjected to downward force, the internal V-shaped steel plate connecting sheet 11 moves upward and the upper fixed steel track is squeezed downward, so that the steel wire rope 15 can be pressed tightly in the steel track groove and tightly pressed between the anti-slip and wear-resistant rubber pad 7, and at the same time, the external clamping lock 3 is buckled, so that the steel wire rope 15 is firmly locked inside the device.
