Desilting door structure of tank body

Abstract

The invention discloses a desilting door structure of a tank body. The desilting door structure comprises a ratchet spring device (1), a lock nut (3), a lock arm (5), a ball head lead screw (6) and a gland (8), wherein the ratchet spring device (1) is connected with the lower left side of the lock arm (5); the gland (8) is positioned between two arms of the lock arm (5); the lock nut (3) is mounted in a symmetric center line of the lock arm (5); and the ball head lead screw (6) is connected between the lock nut (5) and the gland (8). According to the structure, a force applied by the outside is uniformly distributed onto a sealing rubber ring by the ball head lead screw, so that local damage to the sealing rubber ring due to uneven stress is avoided, and a good sealing effect can be achieved.

Description

technical field [0001] The invention relates to an improved structure of a sand discharge door, in particular to a tank body sand discharge door structure. Background technique [0002] Tanker is a tank-shaped transport vehicle used to transport various liquids, liquefied gases and powdered goods, such as gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, various acids Alkali liquid, cement lead oxide powder, etc., tank trucks occupy a very important position in transportation, accounting for about 18% of the total number of trucks. Although there are many types of tank trucks, all of them are integral load-bearing structures. The body of most tank trucks is composed of two parts: the tank body and the chassis. The sand discharge doors (holes) of various tanks (including tanker tanks) are generally clamped and sealed with multiple bolts. It takes time and effort to open and close, and the desired effect cannot be achieved, which redu...

AI Technical Summary

Problems solved by technology

The sand discharge doors (holes) of various tanks (including tanker tanks) are generally clamped and sealed with multiple bolts. It takes time and effort to open and close, and the desired effect cannot be achieved, which reduces work efficiency.

The current sand discharge door is mainly fixed by bolts. This kind of fixing method is prone to local damage to the sealing rubber ring due to uneven force, so that the ideal sealing effect cannot be achieved.
