They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Referring to Figures 1-6, a safety railing for a construction tower crane includes several platform-shaped bases 1, several rectangular columns 2, and several railing frames 3. A guardrail mesh 4 is fixedly welded into each guardrail frame 3. The guardrail frames 3 and the guardrail mesh 4 together form the railing. Each platform-shaped base 1 has a rectangular insert 5 at its upper center. Each rectangular column 2 has a rectangular slot 6 at its lower center, with the slots connected front and back. The rectangular inserts 5 are inserted into the rectangular slots 6, effectively limiting the rectangular columns 2 to their positions on the platform-shaped bases 1. The guardrail frames 3 are positioned between adjacent rectangular columns 2. Three U-shaped mounting blocks 8 are fixedly connected to the left and right side walls. The three U-shaped mounting blocks 8 on the same side are evenly spaced. The openings of the U-shaped mounting blocks 8 are all set away from the rectangular columns 2. The guardrail frame 3 is inserted into the openings of the U-shaped mounting blocks 8 between two adjacent rectangular columns 2. The first bolt 9 is fixedly inserted between the U-shaped mounting blocks 8 and the guardrail frame 3. The U-shaped mounting blocks 8 are used to install and fix the guardrail frame 3 between two adjacent rectangular columns 2. The rectangular insert 5 is welded and fixed to the platform base 1. The positioning block 7 is welded and fixed to the platform base 1 and the rectangular insert 5. The U-shaped mounting blocks 8 are welded and fixed to the rectangular columns 2.
[0025] Positioning blocks 7 are fixedly connected between the left and right sidewalls of several platform-shaped bases 1 and rectangular inserts 5. A locking mechanism is provided between two opposing positioning blocks 7. The locking mechanism is fixedly connected to several guardrail frames 3. The locking mechanism includes L-shaped slots 10 set on several positioning blocks 7. The same support base 11 is inserted into two opposing L-shaped slots 10. Double-headed bolts 12 are fixedly inserted between the inner wall of the L-shaped slot 10 and the support base 11. The two ends of the support base 11 are respectively inserted into the L-shaped slots 10 of the positioning blocks 7 on two adjacent platform-shaped bases 1, and the support base 11 is fixed in the L-shaped slots 10 by the double-headed bolts 12. The upper end of several support bases 11 is provided with two threads. The guardrail frame 3 has two circular holes 14 on both horizontal sections of the column 13 and the guardrail frame 3. Two threaded columns 13 on the same side pass through the two circular holes 14 on the same horizontal plane. Each threaded column 13 is threaded with a washer nut 15. The washer nut 15 is pressed and fixed to the upper end of the guardrail frame 3. The threaded column 13 and the support base 11 are integrally cast. The two threaded columns 13 on the support base 11 pass through the two circular holes 14 on the guardrail frame 3. After the washer nut 15 is threaded onto the threaded column 13, it is pressed and fixed to the guardrail frame 3. This effectively locks and fixes the guardrail frame 3 and the guardrail mesh 4 together, improving the structural stability and safety performance of the guardrail.
[0026] The upper ends of several rectangular posts 2 are equipped with anti-climbing mechanisms. The anti-climbing mechanisms include circular slots 16 respectively set on the upper ends of the left and right sides of several rectangular posts 2. Each of the several circular slots 16 has a fixing rod 17 inserted into it. Each of the several circular slots 16 has a second bolt 18 passing through it on the inner wall of it. The second bolt 18 is used to fix the fixing rod 17 in the circular slot 16. Several second bolts 18 pass through several fixing rods 17 respectively and are pressed and fixed to the inner wall of the circular slot 16. Two barbed wires 19 are fixedly wrapped around the fixing rods 17 between two adjacent rectangular posts 2. The two barbed wires 19 are fixedly wrapped around the fixing rods 17 between two adjacent rectangular posts 2, which effectively prevents people from climbing the guardrail.
[0027] In use, the rectangular inserts 5 on several platform-shaped bases 1 are respectively inserted into the rectangular slots 6 on several rectangular columns 2. The guardrail frame 3 is inserted into the openings of several U-shaped mounting blocks 8 between two adjacent rectangular columns 2, and the guardrail frame 3 is fixed with the first bolt 9. Then, the two threaded posts 13 on the support base 11 are respectively inserted into the two circular holes 14 on the guardrail frame 3. Subsequently, the two ends of the support base 11 are respectively inserted into the L-shaped slots 10 of the positioning blocks 7 on two adjacent platform-shaped bases 1, and the support base 11 is fixed with double-ended bolts 12. The washer nut 15 is threaded onto the threaded post 13 and then pressed and fixed to the guardrail frame 3 within the L-shaped slot 10. This effectively locks and fixes the guardrail composed of the guardrail frame 3 and the guardrail mesh 4, improving the structural stability and safety performance of the guardrail frame 3 and the guardrail mesh 4. Several fixing rods 17 are inserted into the circular slots 16 on several rectangular posts 2. The second bolt 18 is passed through the circular slots 16 and the fixing rods 17 and then locked and fixed. Two barbed wires 19 are fixedly wrapped around the fixing rods 17 between two adjacent rectangular posts 2, effectively preventing people from climbing the guardrail.
