Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In describing embodiments of the present application, it should be noted that, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, interchangeably connected, integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediary, or in communication between two elements. The specific meaning of the above terms in embodiments of the present application will be understood in detail by those of ordinary skill in the art.
Referring to fig. 1 to 4, a cable trench cover according to an embodiment of the present application includes: the chassis 1, the top plate 2, the wedge block 3 and the right-angle buckle assembly 4.
Wherein, chassis 1 is the square form, and is used for pressing from both sides all to be provided with chamfer 11 on locating cable trench 5's both sides end on chassis 1 for chassis 1 increases along top surface to bottom surface cross-sectional area gradually, is provided with voussoir 3 between chamfer 11 and cable trench 5's the trench wall.
Referring to fig. 2, the wedge 3 may be triangular block-shaped, and two sides respectively abut against the chamfer 11 and the trench wall of the cable trench 5. Specifically, the triangular block-shaped wedge 3 may be engaged with the chamfer of the chassis 1, so that when the chassis 1 is pulled upward, the wedge 3 is pressed by the chamfer 11 of the chassis 1, thereby generating a downward friction force to prevent the chassis 1 from rising.
In the present embodiment, the chassis 1 includes a transverse rib and a longitudinal rib. Wherein the transverse ribs can be made of flat steel, round steel, prismatic steel and other materials, and are welded on the longitudinal ribs. The grid structure penetrating along the vertical direction is formed by the plurality of transverse ribs and the longitudinal ribs, so that the deformation energy absorption effect of the grid structure can be enhanced while the mechanical strength is met, and the compressive capacity is increased. Meanwhile, the grid structure can save materials.
In practical application, the underframe 1 can be made into a strip-shaped steel grid plate, cut according to practical requirements on a construction site and applied to nonstandard cable ditches and cable wells.
The top plate 2 is covered on the underframe 1, and a counter bore 21 penetrating in the vertical direction is formed in the top plate 2; the projection of the top plate 2 in the vertical direction covers the projection of the chassis 1 in the vertical direction.
Specifically, the top plate 2 may completely cover the chassis 1 and cover the wedges 3, so that the wedges 3 cannot be removed before the top plate 2 is not removed, that is, before the top plate 2 is moved, the chassis 1 is difficult to be moved.
The right angle buckle assembly 4 includes: a tab lever 41 and a right angle lever; the right angle pole includes: a vertical rod 42 and a short rod 43; the short rod 43 is arranged at the bottom end of the vertical rod 42 and is perpendicular to the vertical rod 42; the top end of the vertical rod 42 is provided with a special-shaped hole; the end part of the pull ring lever 41 is provided with a special-shaped column corresponding to the special-shaped hole in shape; the pull ring rod 41 is used for driving the vertical rod 42 to rotate so that the short rod 43 is staggered with the counter bore 21 and is in crossed clamping fit with the underframe 1.
Specifically, the right angle rod can pass through the counter bore and pass through the grid on the underframe 1, and then you change the pull ring rod 41 to drive the right angle rod to rotate, so that the short rod 43 intersects with the grid, and the underframe 1 is fixedly connected with the top plate 2.
The number of the right-angle rods and the counter bores 21 can be multiple, and the right-angle rods and the counter bores 21 are uniformly arranged, so that the underframe 1 and the top plate 2 can be better fixed. The special-shaped holes and the special-shaped columns are very used cross-shaped structures, straight-line structures and the like, and can be special-shaped structures such as crescent-shaped structures or plum-shaped structures and the like, so that the risk of theft caused by rotation of the vertical rods 42 is reduced.
Further, in the present embodiment, the vertical rod 42 is a screw rod; the counter bore 21 is formed by a screw hole and a through hole; the screw hole is in threaded connection with the vertical rod 42; the shape of the through hole is adapted to the shape of the short bar 43.
The vertical rod 42 of the screw rod structure can be in threaded fit with the screw hole, so that a worker can rotate the vertical rod 42 to adjust the orientation of the short rod 43 and the through hole through the pull ring rod 41. After the tab lever 41 is turned to make the short lever 43 coincide with the through hole, the top plate 2 can be moved upward to separate the top plate 2 from the chassis 1.
Further, the top plate 2 may be made of a polymer resin composite material, such as ECM epoxy repair mortar, integrally cast. Because the main bearing function is borne by the underframe 1, the thickness of the top plate 2 can be relatively thin, and the high polymer resin composite material is adopted, so that the rapid solidification can be realized, the bending resistance and compression resistance of the top plate 2 can reach the design strength in a short time, and the requirement of on-site instant manufacturing and instant use can be met.
While the application has been described in detail with reference to the examples, it will be apparent to those skilled in the art that the foregoing description of the preferred embodiments of the application may be modified or equivalents may be substituted for elements thereof, and that any modifications, equivalents, improvements or changes will fall within the spirit and principles of the application.
