[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Embodiment 1, a device for a safety belt hook without unclamping when moving, the structure is referenced Figures 1-2 As shown, it comprises a base 2, the front side of the base 2 is provided with two up-and-down staggered rolling restraint pieces, and the safety belt restraint space is between the two rolling restraint pieces and between the rolling restraint pieces and the base 2.

[0024] The above device is installed at a proper fixed support position for use, the safety belt is placed in the safety belt restraint space, and the safety belt hook of the worker is directly passed through the device without unclamping when it needs to pass through the device. Specifically, the passing process is to slightly lift the safety belt, the safety belt hook moves along the safety belt and touches the rolling restraint piece, and the rolling restraint piece makes the safety belt hook easily and directly pass through the safety belt restraint space of the device through rotation.

[0025] Specifically, the above safety belt is a kind of anti-falling horizontal lifeline, and can also be a safety rope, a safety line, etc.

[0026] The rolling restraint piece is a roller 3 rotatably arranged on the base 2. The roller 3 facilitates the passing of the safety belt hook.

[0027] The roller 3 comprises an inner liner tube arranged at the center, and a plurality of wheel rods are fixedly connected to the inner liner tube in a diverging manner. The wheel rods are preferably arranged in 8, and the function is to facilitate the passing of the safety belt hook.

[0028] The roller 3 is internally provided with a bearing 301, the bearing 301 is sleeved on a bearing shaft 4, and the bearing shaft 4 is installed in the base 2. The rotation of the roller 3 is realized through the bearing shaft 4 and the bearing 301.

[0029] The base 2 is provided with a shaft hole 201 for installing the bearing shaft 4.

[0030] The rear side of the base 2 is connected with one or more brackets 1.

[0031] The bracket 1 comprises a mounting piece 101 bolted with the base 2.

[0032] The base 2 and the mounting piece 101 are provided with mutually adapted mounting holes 202.

[0033] The bracket 1 comprises an arch 102.

[0034] The bracket 1 is provided with two arches 102, which are oppositely arranged, so that the installation is better.

[0035] The device is implemented, and the parts are referenced Figure 3 as shown, and the following sizes, materials and technologies are preferred:

[0036] The base 2 is an iron plate base, and two holes with a diameter of 10 mm and a hole distance of 150 mm on the diagonal line of the iron plate base are drilled as shaft holes 201 for penetrating the bearing shaft 4. The upper half of the iron plate base is drilled with four holes with a diameter of 13 mm as mounting holes 202 for penetrating Φ12 hot-dip galvanized bolts to fix the bracket 1.

[0037] The bracket 1 is that the arch-shaped round steel (arch 102) is welded on the hot-dip galvanized iron block (mounting piece 101) with a length of 100 mm, and four mounting holes 202 with a diameter of 13 mm are also drilled on the hot-dip galvanized iron block 101 according to the hole distance of the four mounting holes 202 of the iron plate base to cooperate with them, and Φ12 hot-dip galvanized bolts are used to fix the bracket on the iron plate base.

[0038] The bearing 301 is embedded in the middle inner lining tube of the roller 3, and the diameter of the roller 3 is 135 mm. The function of the roller 3 is to limit the steel wire rope or safety rope that penetrates into the iron plate base, the roller 3 and the bearing shaft 4 to form a restraint space from jumping out of the device, so as to ensure safety. The size of the restraint space is preferably 90 mm long and 60 mm wide.

[0039] The bearing shaft 4 is sleeved with a wire on both sides, and double nuts are arranged, one of which is an anti-skid nut, one end of which is fixed with the bearing 301, and the other end is fixed on the hole 201 drilled on the diagonal line of the iron plate base.

[0040] The restraint space formed by the device prevents the safety rope or safety line that penetrates into the space from jumping out or running out of the aforementioned device, and achieves the function of restraining the safety rope or safety line in this area. When the safety belt hook passes through the aforementioned device along the safety rope or safety line, it only needs to hold the safety rope or safety line with the hand, and the safety belt hook touches the rolling roller 3, so that it can pass through left and right at will, achieving the purpose of passing through the aforementioned device without unfastening the safety belt hook.

[0041] It should be noted that the aforementioned bracket 1 installation depends on the site, and the safety rope or safety line is usually arranged on the rack pipe. When the safety rope or safety line is arranged on the wall surface or the pipe gallery construction column, the aforementioned bracket 1 can not be used, and a Φ12 expansion bolt is used instead, and the upper half of the iron plate base is fixed by arranging four holes with a diameter of 13 mm. That is, according to the specific circumstances of the site, the mounting hole 202 reserved on the iron plate base can be used to be fixed in different ways.

[0042] It is obvious that the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
