[0023] The utility model provides a protective device for asphalt road construction, such as Figure 1 and Figure 2 As shown, it includes a base ring 1, a lifting ring 2, a protective component 3, a locking mechanism 4 and a clamping block 5; the base ring 1 is arranged on the outside of the manhole cover; the locking mechanism 4 is arranged on the inner side of the base ring 1, the outer side of the lifting ring 2 is connected with the clamping block 5, the clamping block 5 is slidably connected with the locking mechanism 4, and the lifting ring 2 can slide up and down in the base ring 1 and be locked; the end of the lifting ring 2 away from the base ring 1 is connected with the protective component 3; the protective component 3 is arranged above the manhole cover.

[0024] Exemplarily, the base ring 1 and the lifting ring 2 can be connected by the locking mechanism 4 and the clamping block 5, and the lifting ring 2 is arranged inside the base ring 1. The lifting ring 2 can slide up and down inside the base ring 1 through the sliding connection between the clamping block 5 and the locking mechanism 4, and the lifting ring 2 after lifting can be locked by the locking mechanism 4. According to the change of the asphalt paving thickness, the height of the lifting ring 2 relative to the base ring 1 is changed to adjust the height of the protective device, thereby meeting the protection of the manhole cover.

[0025] Exemplarily, after the base ring 1 and the lifting ring 2 are connected, they are both arranged on the outside of the manhole cover. A protective device is provided on the top of the lifting ring 2, which can seal the manhole cover at the top, thereby improving the protection effect of the manhole cover.

[0026] In the present application embodiment, Figure 3 As shown, the locking mechanism 4 includes a vertical groove 41, a bottom groove 42 and a clamping groove 43; the vertical groove 41 is opened on the inner side of the base ring 1 along the axial direction, and the vertical groove 41 extends to the bottom of the base ring 1 away from one end of the protective component 3; the bottom groove 42 is opened on the inner side of the base ring 1 perpendicular to the axial direction, and one end of the bottom groove 42 is connected to the side wall of the vertical groove 41; the clamping groove 43 is opened on the inner side of the base ring 1 perpendicular to the axial direction, and one end of the clamping groove 43 is connected to the side wall of the vertical groove 41; the clamping block 5 can slide in the vertical groove 41, the bottom groove 42 and the clamping groove 43 respectively.

[0027] Exemplarily, the bottom groove 42 is connected to the side wall of the vertical groove 41 away from the protective device, and the side wall of the bottom groove 42 is not connected to the bottom of the base ring 1; the clamping groove 43 is connected to the end of the vertical groove 41 close to the protective device, and the top of the clamping groove 43 is flush with the top of the vertical groove 41 close to the protective device. The clamping groove 43 and the bottom groove 42 are arranged on the same side of the vertical groove 41, and the clamping groove 43 and the bottom groove 42 can also be arranged on different sides of the vertical groove 41.

[0028] Exemplarily, the base ring 1 is placed on the outside of the manhole cover. In the initial state, the block 5 is set in the bottom groove 42. According to the change of the asphalt paving thickness, the relative height of the lifting ring 2 and the base ring 1 needs to be increased. In this case, the lifting ring 2 needs to be driven to rotate manually through the protective component 3, so that the block 5 is rotated out of the bottom groove 42 until the block 5 moves into the vertical groove 41; then the lifting ring 2 is pulled upward until the block 5 moves upward until it is flush with the top of the slot 43, and then the lifting ring 2 is rotated until the block 5 moves into the slot 43 and locked, so as to achieve the purpose of increasing the relative height of the base ring 1 and the lifting ring 2, and avoid the height of the protective device being lower than the height of the asphalt paving. Similarly, according to the change in the thickness of the asphalt paving, it is necessary to lower the relative height of the lifting ring 2 and the base ring 1. In this case, it is necessary to manually drive the lifting ring 2 to rotate through the protective component 3, so that the block 5 is rotated out of the slot 43 until the block 5 moves into the vertical slot 41; then lower the height of the lifting ring 2 downward until the block 5 moves to be flush with the bottom slot 42, and then rotate the lifting ring 2 to move the block 5 into the bottom slot 42.

[0029] In the present application embodiment, Figure 3 and Figure 4 As shown, it also includes a magnetic attraction component 6; a telescopic slot hole 7 is opened at one end of the bottom slot 42 away from the vertical slot 41; the magnetic attraction component 6 is arranged in the telescopic slot hole 7; the magnetic attraction component 6 can slide in the telescopic slot hole 7, and one end of the magnetic attraction component 6 can slide to the inside of the bottom slot 42.

[0030] Exemplarily, the magnetic attraction component 6 can form a magnetic attraction cooperation with the clamping block 5, and use the magnetic attraction force to perform magnetic attraction limiting work on the lifting ring 2 that has not been lifted, so as to prevent the lifting ring 2 from shaking in the working state.

[0031] In the present application embodiment, Figure 4 As shown, the magnetic attraction component 6 includes a telescopic column 61, a magnetic block 62 and a limit block 63; the end of the telescopic column 61 close to the vertical slot 41 is connected to the magnetic block 62; the outer side of the telescopic column 61 is provided with the limit slot 611, the limit block 63 is connected to the telescopic slot hole 7, and the limit block 63 can slide in the limit slot 611; the telescopic column 61 is arranged in the telescopic slot hole 7, the telescopic column 61 can slide in the telescopic slot hole 7, and one end of the telescopic column 61 can slide to the inside of the bottom slot 42.

[0032] Exemplarily, a magnetic block 62 is embedded at one end of the telescopic column 61 close to the vertical slot 41. The magnetic block 62 on the telescopic column 61 can form a magnetic fit with the clamping block 5, and the magnetic force is used to perform magnetic limiting work on the lifting ring 2 that has not been lifted, so as to prevent the lifting ring 2 from shaking in the working state.

[0033] Exemplarily, a limit block 63 that slides with the limit slot 611 is fixed to the inner wall of the telescopic slot 7. When the telescopic column 61 slides along the telescopic slot 7 toward the vertical slot 41, the limit block 63 that slides with the limit slot 611 limits the telescopic column 61, thereby not only limiting the clamping block 5 under the working device through the magnetic block 62, but also automatically unlocking the clamping block 5 when adjusting the height of the lifting ring 2, thereby improving the adjustment efficiency. In addition, the magnetic suction component 6 can be safely and securely installed in the telescopic slot 7 through the limit block 63, and will not be lost during transportation.

[0034] In the present application embodiment, Figure 3 As shown, the slot 43 includes a first slot 431 and a second slot 432; the first slot 431 is opened on the inner side of the base ring 1 perpendicular to the axial direction, and one end of the first slot 431 is connected to the side wall of the vertical slot 41; one end of the second slot 432 is connected to the first slot 431, and the second slot 432 is arranged perpendicular to the first slot 431.

[0035] Exemplarily, the card slot 43 has a locking function, and the first notch 431 and the second notch 432 are "L" shaped. In the initial state, the card block 5 is set in the bottom slot 42. According to the change of the asphalt paving thickness, it is necessary to increase the relative height of the lifting ring 2 and the base ring 1. In this case, it is necessary to manually drive the lifting ring 2 to rotate through the protective component 3, so that the card block 5 is rotated out of the bottom slot 42 and drives the magnetic suction component 6 to slide out along the telescopic slot 7, until the card block 5 is separated from the magnetic suction component 6 and moves into the vertical slot 41; then the lifting ring 2 is pulled upward until The block 5 moves upward until it is flush with the top of the slot 43, and then the lifting ring 2 is rotated until the block 5 moves to the first slot 431, and the end of the first slot 431 sinks to the bottom of the second slot 432. The second slot 432 can be used to limit the block 5, so as to lock the lifting ring 2 after the upward movement, thereby achieving the purpose of increasing the relative height of the base ring 1 and the lifting ring 2, avoiding the height of the protective device being lower than the height of the asphalt paving, and avoiding the shaking of the lifting ring 2 in the working state. Similarly, according to the change in the thickness of the asphalt paving, it is necessary to lower the relative height of the lifting ring 2 and the base ring 1. In this case, it is necessary to manually drive the lifting ring 2 to exit the second slot 432 through the protective component 3, and then rotate the lifting ring 2 to make the block 5 rotate out of the slot 43 until the block 5 moves into the vertical slot 41; then lower the height of the lifting ring 2 downward until the block 5 moves to be flush with the bottom slot 42, and finally rotate the lifting ring 2 until the block 5 moves into the bottom slot 42, and limit the block 5 through the magnetic suction component 6 to prevent the lifting ring 2 from shaking in the working state.

[0036] In the present application embodiment, Figure 4As shown, the magnetic attraction component 6 further includes a damping ring 64 ; the damping ring 64 is disposed on the outer side of the telescopic column 61 , and the damping ring 64 can increase the friction damping between the telescopic column 61 and the telescopic slot 7 .

[0037] Exemplarily, the outer side of the telescopic column 61 is connected with a damping ring 64 that matches the inner wall of the telescopic slot 7. The damping ring 64 can increase the friction damping between the telescopic column 61 and the telescopic slot 7, thereby further preventing the lifting ring 2 from shaking.

[0038] In the present application embodiment, Figure 1 and Figure 2 As shown, the protection assembly 3 includes a cross top frame 31, a center plate 32 and a handle 33; the cross top frame 31 is connected to the end of the lifting ring 2 away from the base ring 1; the cross top frame 31 is connected to the center plate 32, and the handle 33 is connected to the side of the center plate 32 away from the manhole cover.

[0039] Exemplarily, the center plate 32 is connected to the center position of the cross top frame 31, and a handle 33 is connected to the center position of the center plate 32 away from the manhole cover. The handle 33 can drive the lifting ring 2 to rotate and can also operate the lifting and lowering work of the lifting ring 2, which provides convenience for manual operation.
