DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with 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 fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-4The utility model provides a kind of cover for underground comprehensive pipe gallery, including cover 1, the top of cover 1 is equipped with cushion layer 11, cushion layer 11 is anti-skid wear-resistant layer, also provide protection for cover 1, the top of cover 1 is located below cushion layer 11 and is equipped with placing groove 12, bottom wall of placing groove 12 is linear array and is equipped with empty slot 13, bottom wall of placing groove 12 is linear array and is evenly equipped with filling block 3 at the top of empty slot 13, the bottom of cover 1 movably connects with well frame 2, the top of well frame 2 is fixedly installed with sealing ring 21, cover 1 and well frame 2 are sealed after being combined by sealing ring 21, one side of cover 1 and well frame 2 is connected with hinged device 22, the inner wall of well frame 2 is fixedly installed with bracing plate 23, the top surface of bracing plate 23 bottom is installed with hydraulic device 4, the inner wall of well frame 2 is movably connected with auxiliary device 5 between hydraulic device 4 both sides and cover 1.

[0025] The device has the advantages of lightweight, simple mechanical anti-theft, etc. in actual use. The modular installation filling block 3 is provided, which reduces the overall weight of the cover 1, and the structural strength of the cover 1 is basically equal. The cushion layer 11 is laid above the filling block 3, which prolongs the service life of the filling block 3. When a single filling block 3 is highly worn or damaged, only the damaged filling block 3 needs to be replaced by detaching the cushion layer 11. The lock pin 6 and the cover 1 cooperate to achieve the effect of a simple mechanical lock. By rotating the position of the lock pin 6 using a hex wrench, the lock pin 6 can be clamped inside the circular groove 17 to achieve position fixation and anti-theft function.

[0026] Please refer to Figures 1-3 The filling block 3 is made of honeycomb aluminum material, and the inside of the filling block 3 is uniformly provided with honeycomb cavities filled with carbon fiber reinforced resin. Under the same structural strength, the weight is reduced, so that a single person can carry it by hand. When a part is damaged, only the single filling block 3 needs to be replaced, reducing maintenance costs.

[0027] The overall weight of the filling block 3 is relatively light, and the inside of the filling block 3 is filled with lightweight composite material, which enhances the pressure-bearing capacity of the filling block 3 and reduces the weight of the filling block 3. When installing the overall equipment, a single person can carry the filling block 3 by hand, improving installation efficiency. When a single filling block 3 is damaged, only the single filling block 3 needs to be replaced, without the need to replace the entire cover 1, reducing the maintenance cost of the user.

[0028] Please refer to Figures 1-4 The hydraulic device 4 includes a rotating seat A41, a hydraulic machine 42, and a rotating seat B43. The rotating seat A41 is fixedly installed on the top surface of the bracing plate 23 bottom. The hydraulic machine 42 is rotatably installed in the rotating seat A41. The rotating seat B43 is fixedly installed on the bottom wall of the cover 1. The output shaft of the hydraulic machine 42 is rotatably installed in the rotating seat B43. The output shaft is ejected by the hydraulic machine 42 to open the cover 1.

[0029] Please refer toFigures 1-5 A hole groove 14 is arranged between the cushion layer 11 and the cover plate 1, and is located at the opposite side of the supporting plate 23. The top of the cushion layer 11 is located above the hole groove 14 and is provided with a hidden cover 15. During use, the position of the hole groove 14 can be covered by installing the hidden cover 15. The bottom surface of the cover plate 1 is located below the hole groove 14 and is provided with a sliding groove 16. The inside of the cover plate 1 is located above the sliding groove 16 and is provided with a circular groove 17. The length of the sliding groove 16 is equal to the diameter of the circular groove 17. The hole groove 14, the sliding groove 16 and the circular groove 17 are connected internally.

[0030] The sliding groove 16 and the circular groove 17 are arranged to limit the position of the lock pin 6. The traditional cover plate is closed by gravity and lacks corresponding anti-theft devices. The sliding groove 16, the circular groove 17 and the lock pin 6 are arranged to fix the position of the cover plate 1. The hole groove 14 and the hidden cover 15 are arranged to hide the hole groove 14, which is not a common lock hole and cannot be damaged.

[0031] Please refer to Figures 1-5 A lock pin 6 is rotatably installed in the hole groove 14 of the well frame 2. The overall shape of the lock pin 6 is T-shaped. The top of the lock pin 6 is matched with the shape of the sliding groove 16. The size between the top of the lock pin 6 and the circular groove 17 is matched. A hexagonal groove 61 is arranged at the top of the lock pin 6, and the position of the hexagonal groove 61 corresponds to the position of the hole groove 14.

[0032] The hexagonal wrench is inserted into the hole groove 14 to make the hexagonal wrench and the hexagonal groove 61 clamped. The position of the lock pin 6 is changed by rotating the hexagonal wrench. When the direction of the top of the lock pin 6 coincides with the direction of the sliding groove 16, the cover plate 1 can be opened, and the lock pin 6 can slide out of the sliding groove 16. When the direction of the top of the lock pin 6 does not overlap with the direction of the sliding groove 16, the cover plate 1 cannot be opened due to the limitation of the circular groove 17 to the position of the lock pin 6, which realizes the effect of a simple mechanical lock.

[0033] Working principle: when installing the whole device, install the well frame 2 at the entrance and exit of the pipe gallery, install the cover plate 1 on the top of the well frame 2, then fill the top of the cover plate 1 with the filler block 3 one by one to enhance the pressure bearing capacity of the cover plate 1, then lay the cushion layer 11 on the top of the filler block 3 to achieve the anti-skid and wear-resistant effect, after the cover plate 1 is combined with the well frame 2, the top of the lock pin 6 is located in the circular groove 17, the hexagonal wrench is inserted into the hole slot 14 and then clamped into the hexagonal groove 61, the hexagonal handle is rotated to drive the lock pin 6 in the circular groove 17 to rotate, after rotating 90°, the circular groove 17 limits the position of the lock pin 6 to achieve the locking effect, then cover the hidden cover 15 above the hole slot 14 to hide, when the user needs to open it, the hexagonal wrench is inserted into the hole slot 14 and clamped with the hexagonal groove 61, the lock pin 6 is rotated to overlap with the sliding groove 16 and then pulled out, at this time, due to the angle of the lock pin 6, the circular groove 17 cannot be limited, and the cover plate 1 is moved to achieve the opening effect;

[0034] Because of long use time or accidental damage to the cover plate 1, the conventional cover plate 1 needs to be replaced as a whole, but the device only needs to disassemble the cover plate 1 and replace the damaged single filler block 3, so as to facilitate the maintenance and maintenance of the device.
