Manhole cover automatic locking device and intelligent powder and particle material transportation tank car

Abstract

The invention discloses an automatic manhole cover locking device and an intelligent powder and particle material transportation tank car, and relates to the technical field of powder and particle material transportation tank car equipment.The automatic manhole cover locking device comprises a rotating part rotationally arranged on a manhole cover, a rotation driving part used for driving the rotating part to rotate and a plurality of clamping parts; a clamping opening is formed in the clamping seat, the clamping part comprises a first connecting rod and a pin shaft which are hinged to each other, the end part of the first connecting rod is hinged to the rotating part, the pin shaft is arranged in the guide seat in a penetrating manner, the end part of the pin shaft extends into the clamping opening to be clamped when the rotating part rotates forwards, and the end part of the pin shaft is separated from the clamping opening when the rotating part rotates backwards; due to the fact that the clamping parts are all hinged to the rotating parts, when the rotating parts rotate, the rotating parts can be driven to rotate at the same time, the locking action is more synchronous, and the manhole cover can be locked easily; and only one rotating driving part is arranged, so that the structure is simpler, the operation is more convenient, and the equipment cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of equipment for transporting powder and granular materials, in particular to an automatic locking device for a manhole cover and an intelligent tank truck for transporting powder and granular materials. Background technique [0002] Powder material transport tanker, also known as bulk cement truck, is composed of special vehicle chassis, bulk cement tank body, gas pipeline system, automatic unloading device and other parts, suitable for fly ash, cement, lime powder, ore powder, granular alkali, etc. The particle diameter is not more than 0.1mm for bulk transportation of powder dry materials, mainly used in cement plants, cement warehouses and large construction sites, which can save a lot of packaging materials and loading and unloading labor. [0003] The traditional tanker manhole device is composed of a manhole cover and a manhole collar. The traditional mechanical 6-point or 8-point positioning and lock...

Problems solved by technology

[0003] The traditional tanker manhole device is composed of a manhole cover and a manhole collar. The traditional mechanical 6-point or 8-point positioning and locking bolts are used to lock the two. When opening and closing, people need to climb to the top of the tank to unscrew them. The bolts then open the manhole cover to load the material. After the completion, the above bolts are artificially locked, which increases the possible danger caused by personnel climbing, and the operation is cumbersome, which increases labor costs and wastes time; for example, the application number is "201721194391.0" Utility model patent for "a bulk powder transport tank"

In the utility model patent with the application number "202022359054.0" and the name "An automatic manhole device for tanks", it uses several cylinders to respectively drive the compression device to compress the manhole cover, but its cylinder, compression The devices are equipped with multiple groups correspondingly, and the structure is relatively complicated
