Specific meanings of the above terms in the embodiments of the present application can be understood in specific cases 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 invention includes: the device comprises an underframe 1, a top plate 2, a wedge 3 and a right-angle buckle component 4.
Wherein, chassis 1 is the square shape, and is used for pressing from both sides end that the clamp was located cable pit 5 on chassis 1 and all is provided with scarf 11 for chassis 1 increases along top surface to bottom surface cross-sectional area gradually, is provided with voussoir 3 between scarf 11 and the trench wall of cable pit 5.
Referring to fig. 2, the wedge 3 may be a triangular block, and two sides thereof abut against the chamfer 11 and the wall of the cable trench 5, respectively. Specifically, the triangular wedge 3 may engage with the chamfered surface of the base frame 1, so that when the base frame 1 is pulled to move upward, the wedge 3 is pressed by the chamfered surface 11 of the base frame 1, thereby generating a downward frictional force to prevent the base frame 1 from being lifted.
In the present embodiment, the chassis 1 includes lateral ribs and longitudinal ribs. The transverse ribs can be made of flat steel, round steel, edge steel and other materials and are welded on the longitudinal ribs. The grid structure that runs through along vertical direction is constituteed with vertical rib to many horizontal ribs, can strengthen its deformation energy-absorbing effect when satisfying mechanical strength, increases compressive capacity. Meanwhile, the grid structure can save the use of materials.
In practical application, the underframe 1 can be made into a strip-shaped steel grating plate, and is cut according to actual requirements on a construction site, so that the underframe is applied to non-standard cable trenches and cable wells.
The top plate 2 is covered on the bottom frame 1, and a counter bore 21 penetrating through the top plate 2 along the vertical direction is arranged on the top plate; the vertical projection of the top plate 2 covers the vertical projection of the bottom frame 1.
Specifically, the top plate 2 can be completely covered on the bottom frame 1 to cover the wedges 3, so that the wedges 3 cannot be removed before the top plate 2 is removed, that is, the bottom frame 1 is difficult to move before the top plate 2 is moved.
The right-angle snap-fit component 4 includes: a pull ring rod 41 and a right-angle rod; the right-angle pole includes: a vertical bar 42 and a short bar 43; the short rod 43 is arranged at the bottom end of the vertical rod 42 and is vertical 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 rod 41 is provided with a special-shaped column corresponding to the shape of the special-shaped hole; 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 chassis 1.
Specifically, the right-angle rod can pass through the counter bore and pass through the grid on the bottom frame 1, and then the pull ring rod 41 is changed to drive the right-angle rod to rotate, so that the short rod 43 is intersected with the grid, and the bottom frame 1 is fixedly connected with the top plate 2.
The right-angle rods and the counter bores 21 can be arranged in a plurality of numbers and 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 structures which are not commonly used and are in a cross shape, a straight shape and the like, and can be special structures such as a crescent shape or a plum blossom shape, so that the risk of theft caused by the fact that the vertical rod 42 is rotated 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 which are communicated; 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 matched with the screw thread, so that a worker can rotate the vertical rod 42 to adjust the positions of the short rod 43 and the through hole through the pull ring rod 41. After rotating the right-angle rod through the pull ring rod 41 to enable the short rod 43 to be overlapped with the through hole, the top plate 2 can be moved upwards to enable the top plate 2 to be separated from the bottom frame 1.
Further, the top plate 2 may be made of a polymer resin composite material, such as ECM epoxy repair mortar, and integrally cast. The main bearing function is borne by the bottom frame 1, so that the thickness of the top plate 2 can be thinner, the high polymer resin composite material is adopted, the rapid solidification can be realized, the bending resistance and the compression resistance of the top plate 2 can reach the design strength in a short time, and the requirement of on-site instant manufacture and instant use is met.
Although the present invention has been described in detail with reference to examples, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
