[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Please refer to Figures 1 to 4 , the present utility model provides a column protection device for a construction site, which includes a first protective outer plate 1. A second protective outer plate 2 is arranged on the back surface of the first protective outer plate 1. Two fixed blocks 3 are fixedly connected to the inner wall of the first protective outer plate 1. A limit block 4 is slidably connected to the inside of each fixed block 3. A return spring 5 is fixedly connected to one side surface of the two limit blocks 4 close to each other. One end of the two return springs 5 away from each other is fixedly connected to the inner side wall of the fixed block 3. Three limit holes 6 are opened on the left and right side surfaces of the second protective outer plate 2. Three limit rods 7 are fixedly connected to the inner side wall of each limit block 4. One end of the two groups of limit rods 7 close to each other extends into the inside of the limit hole 6. Auxiliary blocks 8 are fixedly connected to the inner walls of the first protective outer plate 1 and the second protective outer plate 2. A threaded rod 9 is rotatably connected to the inside of each auxiliary block 8. A moving block 10 is threadedly connected to the outer surface of each threaded rod 9. Each moving block 10 is slidably connected to the inside of the auxiliary block 8. A damper 11 and a damper spring 13 are fixedly connected to one side surface of the two moving blocks 10 close to each other. The damper 11 is located inside the damper spring 13. One end of each group of damper 11 and damper spring 13 close to each other is fixedly connected to the clamping plate 12 together.

[0024] The first protective outer plate 1 and the second protective outer plate 2 are installed by the cooperation of the limiting rod 7 and the limiting hole 6. By pulling the limiting block 4, the limiting rod 7 is moved out of the limiting hole 6, so that the two first protective outer plates 1 and the second protective outer plate 2 are separated. Then, by rotating the threaded rod 9, the moving block 10 drives the clamping plates 12 to approach or move away from each other, so as to clamp and loosen columns with different diameters, realizing the ability of convenient loading and unloading, without consuming a large amount of time. When the protective outer plate is impacted, the impact force is gradually buffered through the cooperation of the damper 11 and the damping spring 13, avoiding the direct transmission of the impact force to the column. At the same time, the durability of the first protective outer plate 1 and the second protective outer plate 2 can also be improved, effectively improving the protection effect on the column.

[0025] Furthermore, a stabilizing block 14 is fixedly connected to the upper surface of each limiting block 4. Each stabilizing block 14 is slidably connected to the inside of the fixed block 3. The stabilizing block 14 can move simultaneously with the limiting block 4, and use its own friction against the fixed block 3 during movement to improve the stability of the limiting block 4 during movement, and can also limit the moving distance of the limiting block 4.

[0026] Furthermore, auxiliary handles 15 are fixedly connected to the mutually remote side surfaces of the two limiting blocks 4. An anti-slip sleeve 16 is fixedly connected to the outer surface of each auxiliary handle 15. The auxiliary handle 15 can provide a good force application position for the limiting block 4, increasing the convenience when the limiting block 4 needs to be pulled. The anti-slip sleeve 16 can improve the firmness when grasping the auxiliary handle 15.

[0027] Furthermore, two stabilizing blocks 17 are fixedly connected to the outer surface of each auxiliary handle 15. One end of each group of stabilizing blocks 17 close to each other is fixedly connected to the mutually remote side surface of the limiting block 4. The stabilizing blocks 17 can increase the fixed connection area between the auxiliary handle 15 and the limiting block 4, making the connection relationship between the two more firm, avoiding the possibility of breakage at the connection after long-term use, and increasing the firmness of the device.

[0028] Furthermore, an auxiliary bearing 18 is sleeved on the outer surface of each threaded rod 9. Each auxiliary bearing 18 is embedded in the inner wall of the auxiliary block 8. The auxiliary bearing 18 can reduce the friction generated when the threaded rod 9 rotates, make the threaded rod 9 more sensitive when rotating, and at the same time can also reduce the wear degree of the threaded rod 9 and increase the service life of the threaded rod 9.

[0029] Furthermore, rotating handles 19 are fixedly connected to the mutually remote ends of the two threaded rods 9. A grip 20 is fixedly connected to the outer surface of each rotating handle 19. Through the cooperation of the rotating handle 19 and the grip 20, an effective force application position can be provided for the threaded rod 9, increasing the convenience when the threaded rod 9 needs to be rotated, and effectively increasing the convenience of the device.

[0030] Furthermore, a sliding block 21 is fixedly connected to the upper surface of each moving block 10. Each sliding block 21 is slidably connected to the inside of the auxiliary block 8. The sliding block 21 can move simultaneously with the moving block 10 and use the friction against the auxiliary block 8 during its movement to improve the stability of the moving block 10 during movement and can also limit the moving distance of the moving block 10.

[0031] Furthermore, a protective pad 22 is fixedly connected to one side surface of each of the two clamping plates 12 that are close to each other. A plurality of groups of rubber blocks 23 arranged at equal distances are fixedly connected to one side surface of each of the two protective pads 22 that are close to each other. The protective pad 22 can reduce the damage caused to the upright column during the clamping process of the clamping plate 12. At the same time, the rubber blocks 23 can further improve the buffering capacity of the clamping plate 12 and effectively improve the protection of the upright column.

[0032] Working principle: When in use, first take the first protective outer plate 1 and the second protective outer plate 2 to a suitable position. When it is necessary to protect the upright column, first pull the two auxiliary handles 15, thereby driving the two limit blocks 4 to move away from each other within the fixed block 3. The stabilizing block 14 can limit the moving distance of the limit block 4, thereby causing the limit rods 7 to move away simultaneously. Then align the first protective outer plate 1 and the second protective outer plate 2 and release the auxiliary handles 15. Use the contraction force of the return spring 5 to drive the limit rods 7 to insert into the limit holes 6, thereby combining the first protective outer plate 1 and the second protective outer plate 2. Then rotate the handle 19 clockwise to rotate the threaded rod 9. The auxiliary bearing 18 can reduce the sensitivity of the threaded rod 9 during rotation, thereby causing the two moving blocks 10 to drive the clamping plates 12 to approach each other and making the protective pads 22 and the rubber blocks 23 contact the upright column, so as to protect it by relying on the first protective outer plate 1 and the second protective outer plate 2. When it is necessary to disassemble, reverse-rotate the handle 19, thereby reversing the threaded rod 9 and causing the moving blocks 10 to move away from each other, thereby separating the clamping plates 12 and the protective pads 22 from the upright column. Then pull the auxiliary handles 15 to make the limit blocks 4 drive the limit rods 7 to move out of the limit holes 6, and then disassemble the first protective outer plate 1 and the second protective outer plate 2, achieving the ability of convenient disassembly and assembly and effectively improving the convenience during use. When the first protective outer plate 1 or the second protective outer plate 2 is impacted during protection, the damping effect generated by the cooperation of the damping spring 13 and the damper 11 will gradually relieve the impact force, making it have an effective buffering capacity, avoiding the impact force being directly transmitted to the upright column, and at the same time can also improve the service life of the first protective outer plate 1 and the second protective outer plate 2, effectively increasing the protection ability of the upright column.
