DETAILED DESCRIPTION

[0026] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0027] Please refer to Figures 1-8 The utility model provides a construction protection wellhead cover plate, including steel cover plate 1 and four groups of limiting column 7, the upper surface annular equidistance of steel cover plate 1 is set with four groups of main circular groove 12, the bottom surface of main circular groove 12 is set through with through hole 13, the upper surface of steel cover plate 1 is fixedly connected with a plurality of recess type lifting eye 2, the inside rotationally connected with movable axle rod 3 of through hole 13, the outside of movable axle rod 3 and located in the inside fixedly connected with hex ring seat 31 of main circular groove 12, the outside of movable axle rod 3 and located below steel cover plate 1 fixedly connected with gear 4, the side of gear 4 is engaged with rack 5, the lower surface of steel cover plate 1 is annular equidistance fixedly connected with four groups of slide rail 6, rack 5 is slidably connected below slide rail 6, four groups of limiting column 7 can be detachably connected in one end of rack 5, the upper side of main circular groove 12 is movably connected with end cover 8.

[0028] The utility model discloses a steel cover plate 1's lower surface is provided with four groups of adjustable limit post 7, has enhanced the fixity of steel cover plate 1 obviously. Limit post 7 is closely combined with the inner wall of well mouth, effectively prevents the situation that steel cover plate 1 is taken away when paving machine or leveling machinery constructs. The position of four groups of limit post 7 is in adjustable state, can be correspondingly adjusted according to the diameter of different well mouth, makes the applicability stronger. The specific working process is: using excavator or forklift hoists steel cover plate 1 to the well mouth above, makes steel cover plate 1 completely covers well mouth. After placing steel cover plate 1, adjust the position of four groups of limit post 7 respectively (since four groups of limit post 7 are in the state of being separately adjustable, thus when placing steel cover plate 1, need not to consume energy to align the center of steel cover plate 1 with the center of well mouth, only need to cover well mouth completely, reduces the time of repeated positioning). Then using sleeve wrench rotates hex ring seat 31, makes it drive movable shaft 3 and gear 4 rotate, the rack 5 meshing with gear 4 will produce displacement change, and then the rack 5 drives limit post 7 to move to the well mouth wall, until with the well mouth wall is combined.

[0029] Specifically, the function of the lifting eye 2 is to use excavator or forklift to hoist the steel cover plate 1. The recessed structure can ensure that the upper surface of the steel cover plate 1 is in a flat state.

[0030] Specifically, the function of the end cap 8 is to seal the main circular groove 12, which can prevent construction materials or external pollutants from entering the inside of the main circular groove 12.

[0031] Specifically, the thickness of the steel cover plate 1 is designed to be 20mm or more to ensure that it has sufficient strength and durability during construction. The steel cover plate 1 with such thickness can effectively withstand the rolling of road rollers or other heavy machinery without deformation or lifting. Such design not only improves the carrying capacity of the steel cover plate 1, but also enhances its stability and durability, reduces the frequency of maintenance and replacement, and improves the safety of the construction process.

[0032] Specifically, the slide rail 6 supports the rack 5, ensuring that the rack 5 can move stably during operation. Preferably, the length of the slide rail 6 is set to be less than half of the radius of the steel cover plate 1, so that the slide rail 6 is pre-set at a certain distance from the peripheral edge of the steel cover plate 1. When the steel cover plate 1 covers the well mouth, the lower surface edge of the steel cover plate 1 can be completely combined with the well mouth, and the existence of the slide rail 6 will not interfere with the covering and combining effect of the steel cover plate 1.

[0033] Further, the outer wall of the movable shaft 3 below the hex ring seat 31 is provided with a lower threaded buckle 32, the outer side of the lower threaded buckle 32 is threaded with a hex nut 33, and the diagonal length of the hex nut 33 is greater than the diagonal length of the hex ring seat 31.

[0034] Specifically, when the position adjustment of the limiting column 7 is completed, the hexagonal nut 33 is fastened using a socket wrench, so that the lower surface of the hexagonal nut 33 abuts against the bottom surface of the main circular groove 12, and at this time the movable shaft 3 is locked and fixed. The diagonal length of the hexagonal nut 33 is greater than the diagonal length of the hexagonal ring seat 31, and the purpose of this setting is that when the hexagonal nut 33 is braked using the socket wrench, the hexagonal ring seat 31 will not be braked at the same time.

[0035] Further, the outer wall of the movable shaft 3 and above the hexagonal ring seat 31 is provided with an upper threaded buckle 34, and the lower surface of the end cover 8 is fixedly connected with a fixed sleeve 81, and the fixed sleeve 81 is threadedly sleeved outside the upper threaded buckle 34, and the upper surface of the end cover 8 is annularly and equidistantly fixedly connected with a plurality of protrusions.

[0036] Specifically, the end cover 8 plays a protective role. After the hexagonal nut 33 is fastened, the fixed sleeve 81 can be threadedly sleeved outside the upper end of the movable shaft 3, and at this time the end cover 8 covers the main circular groove 12, which can prevent construction materials or other sundries from entering the main circular groove 12, thereby protecting the internal components of the main circular groove 12 from being contaminated or damaged. When disassembling the end cover 8, the worker can indirectly rotate the end cover 8 by rotating the plurality of protrusions on the upper surface of the end cover 8.

[0037] Further, the upper surface of the steel cover plate 1 is annularly and equidistantly provided with four groups of mounting grooves 11, and the lifting ring 2 is fixedly connected inside the mounting grooves 11.

[0038] Specifically, the lifting ring 2 is provided in a recessed shape, and such a shape enables the lifting ring 2 to be embedded in the upper surface of the steel cover plate 1 without protruding from the steel cover plate 1, so that the upper surface of the steel cover plate 1 remains in a planar state.

[0039] Further, the upper surface of the rack 5 is fixedly connected with a plurality of fixed seats 51, both sides of the fixed seat 51 are rotatably connected with a plurality of rollers 52, and the rollers 52 are slidingly connected inside the sliding rail 6.

[0040] Specifically, when the rack 5 moves, the rack 5 drives the rollers 52 to slide inside the sliding rail 6 through the fixed seat 51, so that the movement of the rack 5 is smoother.

[0041] Further, the rack 5 is fixedly connected with a fixed block 53 at one end close to the limiting column 7, and the limiting column 7 is fixedly connected with two groups of ear plates 71 at one side close to the rack 5, and the two groups of ear plates 71 are fixed to the fixed block 53 through bolts.

[0042] Specifically, the limiting column 7 and the fixed block 53 adopt a detachable structure, which is convenient for subsequent replacement and maintenance of the limiting column 7.

[0043] Further, the lower surface center of the steel cover plate 1 is fixedly connected with a sleeve 9, the lower surface of the sleeve 9 is fixedly connected with a bottom plate 91, the diameter of the bottom plate 91 is less than half the length of the diameter of the steel cover plate 1, and a plurality of support rods 92 are fixedly connected between the bottom plate 91 and the steel cover plate 1.

[0044] Specifically, the bottom plate 91 serves to provide a flat placement surface for the steel cover plate 1 and the components below, facilitating transportation and stability.

[0045] The above is only the preferred embodiment of the present application, and is not used to limit the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection scope of the present application.
