Cable trench cover plate supporting seat

Abstract

The invention provides a cable trench cover plate supporting seat. The cable trench cover plate supporting seat comprises a foundation, wherein the foundation is fixedly connected with a fixing block,the fixing block is internally provided with a sliding groove, the sliding groove is internally equipped with a first supporting block in a sliding mode, a side wall of the fixing block is provided with a first through hole, a side wall of the first supporting block is provided with a second through hole corresponding to the first through hole, the first through hole and the second through hole are respectively internally provided with a first fixing bolt which is respectively in plugging connection with the first through hole and the second through hole, and the first fixing bolts are provided with first locking nuts in threaded connection with the first fixing bolts. The cable trench cover plate supporting seat has advantages of strong mounting stability in a cable trench, simple operation, convenient dismounting, repeatable utilization and accurate height adjustment.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a support seat for a cable trench cover plate. Background technique [0002] When arranging electrical equipment on the second floor of an indoor substation, it is generally necessary to design ground cable trenches. The usual practice is to increase the thickness of the surface layer without changing the structure layer. However, with the construction of intelligent substations, the number of cables in the trench has increased greatly, and the size of general cable trenches is difficult to meet the requirements of intelligent substations. The width of cable trenches has been increased. Deformation makes it impossible to use normally. The thickness of ordinary reinforced concrete cover plate is large, which will reduce the effective depth of cable trench; the cost of composite cable trench cover plate is high, and none of them meet the requirements. The staff considers setting a supporti...

However, with the construction of intelligent substations, the number of cables in the trench has increased greatly, and the size of general cable trenches is difficult to meet the requirements of intelligent substations. The width of cable trenches has been increased. Deformation makes it impossible to use normally. The thickness of ordinary reinforced concrete cover plate is large, which will reduce the effective depth of cable trench; the cost of composite cable trench cover plate is high, and none of them meet the requirements. The staff considers setting a supporting cover plate in the cable trench To continue to use 5mm thick checkered steel plate

[0003] The existing method is to preset a certain height of cement blocks in the cable trench as a support. This method has a fixed height and cannot be adjusted in height. The cement prefabricated support cannot be used again, and other movable support equipment will have position deviation in the cable trench under the uneven pressure of the cover plate, which cannot meet the support requirements
