[0001] The utility model belongs to the technical field of river channel construction equipment, and in particular relates to a safety anti-falling device for river channel facade construction. Background Art

[0002] At present, the construction of the facade of the river channel wall basically relies on setting up scaffolding on the riverbed as an operating platform during the dry season, and adopts a scaffolding operation method similar to that in land engineering, by building a scaffolding platform as an operating platform to provide work support for construction personnel. This operation method has the following disadvantages: First, the construction process is cumbersome, and it is necessary to do cofferdam construction and other construction before construction to form an operating environment where the scaffolding can be disassembled and assembled; second, the construction process is carried out section by section along the extension direction of the river channel. After each section of the river channel facade construction is completed, the support of the next section needs to be rebuilt, and the disassembly and assembly are cumbersome and laborious, which affects the construction period; third, the existing auxiliary construction facilities are usually open platforms with poor safety and stability, and workers face safety issues during construction.

[0003] In summary, it is necessary to develop and design a safety anti-fall device for river channel facade construction to solve the aforementioned technical problems. Utility Model Content

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0021] See also Figure 1 , Figure 2 and Figure 3 The safety anti-falling device for river channel facade construction of the utility model comprises a rectangular support frame 3, a support panel 9 is installed on the top of the support frame 3, and a circular closed safety guardrail 6 is installed on the support frame 3.

[0022] The support frame 3 and the support panel 9 together constitute a construction platform for supporting construction personnel and materials. During the construction process, materials are transferred to the construction platform using a crane, and construction personnel move on the construction platform. The surrounding safety guardrails 6 effectively prevent construction personnel and materials from falling from the construction platform. During construction, construction personnel can further connect the safety lock on the safety harness to the safety guardrail 6 to further prevent falling accidents.

[0023] See also Figure 4 It can be seen that: in this embodiment, the supporting base frame 3 includes corner end blocks 3-1 located at the four corners, and also includes two long frames 3-2 and two short frames 3-3. The ends of the long frames 3-2 and the short frames 3-3 are welded and fixed to the corresponding corner end blocks 3-1, and a plurality of reinforcing connecting beams 3-4 are installed between the two long frames 3-2. The ends of the reinforcing connecting beams 3-4 are welded and connected to the long frames 3-2.

[0024] In this embodiment, the long frame 3-2 and the short frame 3-3 are both C-shaped steel and the notches are facing outward. Furthermore, a plurality of guardrail fixing seats 3-5 are respectively arranged in the profile grooves of the long frame 3-2 and the short frame 3-3. The guardrail fixing seats 3-5 are C-shaped steel segments and their width is smaller than the groove width of the long frame 3-2 and the short frame 3-3. Vertically through-holes are arranged in the guardrail fixing seats 3-5 and the frame positions (long frame 3-2 and short frame 3-3) where they are located. The bottom of the safety guardrail 6 is plugged into the corresponding jack and locked with a bayonet. When the safety guardrail 6 needs to be disassembled, only the bayonet at the bottom needs to be removed. After the bayonet is removed, the safety guardrail 6 can be pulled out upward and separated from the supporting chassis 3.

[0025] Two telescopic sleeves 5 are installed in the middle of the supporting frame 3. A telescopic tube 6 is inserted and installed inside each telescopic sleeve 5. A threaded hole is provided on the bottom wall of the telescopic sleeve 5 and a positioning screw 10 is provided in the threaded hole. A plurality of positioning holes arranged at equal intervals are provided on the bottom wall of the telescopic tube 7 and the ends of the positioning screws 10 are located in the positioning holes. The front end of the telescopic tube 7 is against the river channel facade and the port is combined with the positioning piece. Figure 3 As shown in FIG, the rear end of the telescopic sleeve 5 is welded and fixed to the rear long frame 3-2, and the front end of the telescopic sleeve 5 extends out from the window opened on the front long frame 3-2 and is welded and fixed.

[0026] By adjusting the positioning screw 10, the telescopic movement of the telescopic tube 7 in the telescopic sleeve 5 can be adjusted, thereby adjusting the distance that the front end of the telescopic tube 7 extends forward (i.e., the distance between the front end of the telescopic tube 7 and the front edge of the supporting chassis 3). Specifically, the positioning screw 10 is first rotated to make its end escape from the positioning hole on the side wall of the telescopic tube 7, and then the telescopic tube 7 is adjusted to move forward or backward, and when the position is appropriate, the positioning screw 10 is rotated again to make its end insert into a positioning hole on the side wall of the telescopic tube 7 again.

[0027] During construction, positioning pieces are set on the river channel facade to assist in construction. The positioning pieces can usually be metal positioning blocks anchored on the river channel facade with anchor nails. The front port of the telescopic tube 7 of the present safety anti-falling device is combined with the metal positioning block (that is, the metal positioning block is embedded in the front port of the telescopic tube 7). This can effectively prevent the present safety anti-falling device from any lateral displacement on the river channel facade during construction. Usually, shaking problems are prone to occur under the action of wind. By setting the telescopic tube 7 in combination with the positioning piece, the aforementioned shaking problem can be effectively alleviated or even avoided, thereby improving the safety of construction operations.

[0028] A roller assembly 4 is installed at the front of the support frame 3 and outside the two telescopic sleeves 5. The roller assembly 4 includes rollers 4-5 that can be displaced forward and backward, and the rollers 4-5 roll along the river channel facade. The purpose of setting the roller assembly 4 is that when the safety anti-falling device moves horizontally along the river channel facade, the rolling movement of the rollers 4-5 on the river channel facade reduces the resistance of the safety anti-falling device when it moves.

[0029] See also Figure 5 , we can see that:

[0030] The roller assembly 4 includes an outer sleeve 4-1 and a telescopic shaft tube 4-2 located in the outer sleeve 4-1, and the outer sleeve 4-1 is welded and fixed to the reinforced connecting beam 3-4 at the location. A wheel seat 4-4 is provided at the front end of the telescopic shaft tube 4-2 and a roller 4-5 is installed on the wheel seat 4-4, and the roller 4-5 can rotate flexibly. A nut is installed on the side wall of the outer sleeve 4-1 and a threaded rod is installed in the nut, and an adjusting hand wheel 4-3 is installed at the outer end of the threaded rod. Positioning holes arranged at equal intervals are provided on the side wall of the telescopic shaft tube 4-2 and the inner end of the threaded rod is located in the positioning hole.

[0031] By operating the adjustment hand wheel 4-3, the telescopic shaft tube 4-2 can be adjusted to shift forward or backward, so that the position of the roller 4-5 (that is, the distance between the roller 4-5 and the front edge of the supporting frame 3) is adjusted and set.

[0032] A pull cable 2 is connected to both the left and right sides of the support frame 3, and a safety hook 1 is provided at the end of the pull cable 2. The pull cable 2 and the safety hook 1 constitute a safety belt assembly. Figure 2As shown in , the ends of the two cables 2 are fixedly connected to the two rear corner end blocks 3-1. During the construction process, the safety anti-fall device is moved by a crane and connected to the anchoring facilities on the shore by two safety belt assemblies, which can prevent the safety anti-fall device from falling when extreme situations such as the crane tipping over and the cable breaking occur, thereby further ensuring safety.

[0033] Two left and right lifting rings 8 are also installed on the support frame 3. The lifting rings 8 are used to connect with the lifting cables and hooks of the crane equipment. In this embodiment, the lifting ring 8 is located above the support panel 9, and includes a lifting ring base and a lifting ring body hingedly connected to the base. The lifting ring base is fixedly connected to the reinforced connecting beam 3-4 at the location by bolts. When in use, the lifting ring body stands upright, and when not in use, the lifting ring body tilts to the side.

[0034] Directions:

[0035] The lifting cable of the small crane equipment located on the river bank is connected to the two lifting rings 8 of the safety anti-falling device, and the two safety hooks 1 are connected to the anchoring facilities on the shore and the cable 2 should be properly tensioned; according to the situation of the river facade, the positions of the rollers 4-5 of the two roller assemblies 4 are adjusted first, and the rollers 4-5 should be pressed on the river facade; when the safety anti-falling device is shifted along the river facade, the small crane equipment is operated to move along the length direction of the river. During this process, at least one safety hook 1 should be connected to the anchoring facilities on the shore. During the shifting process, the rollers 4-5 of the roller assembly 4 roll and move on the river facade; after moving into place, the two sets of positioning screws 10 are adjusted from the bottom to shift the two telescopic tubes 7 forward until they are combined with the positioning parts pre-set on the river facade; then the construction personnel and construction materials can be transferred to the safety anti-falling device, that is, the construction platform, and the above process is repeated after the construction of each river facade segment is completed to shift to the next construction segment.
