Abstract

A manhole cover comprises a cover body; a flap which is arranged at an edge part of the manhole cover and used for fixing the cover body; a locking pressure plate which is arranged at the edge part of the manhole cover and used for locking the manhole cover when the manhole cover is closed; preferably, the manhole cover further comprises a locating device which is used for fixing the manhole cover when the manhole cover is opened to an certain angle; and the locating device comprises a locating plate which is connected to the cover body and in which a locating hole is arranged; a locating pin which is matched with the locating hole and fixes the manhole cover by inserting the locating pin into the locating hole; and a locating pin bracket which is used for fixing the locating pin; wherein, the locating pin is provided with a first location into which the locating hole is inserted and a second position from which the locating hole is separated, thus the locating pin can be reliably fixed when the manhole cover is opened, which avoids the permanent deformation of the manhole cover due to collision of the manhole cover resulting from carelessness of an operator or other external factors, and can guarantee the manhole cover realizes the normal sealing function.

Description

technical field [0001] The invention relates to logistics equipment, in particular to a manhole cover with a positioning device and a tank type pallet box with the manhole cover. Background technique [0002] The currently used tank pallet box usually has a manhole and a manhole cover for closing the manhole. The manhole cover of the current tank pallet box usually leans directly on the tank body or frame after opening. Due to the operation The carelessness of the operator or other external factors can easily cause the manhole cover to be knocked and permanently deformed, so that the normal sealing performance cannot be guaranteed. In addition, since the manhole cover cannot be fixed in position after opening, it is not possible to safely and reliably turn the tank pallet box upside down for unloading. Contents of the invention [0003] An object of the present invention is to provide a manhole cover with a positioning device, so as to solve the problem in the prior art t...
