Connector for connecting loading arm with tank truck

Abstract

The invention discloses a connector for connecting a loading arm with a tank truck. The connector comprises a base, at least three shaft lugs uniformly distributed and fixed along the outer edge of the base, and a rotary plate rotationally connected with the base, wherein each shaft lug is hinged with a clamping jaw used for connecting the base with the connector end of the tank truck; arc-shaped grooves corresponding to the clamping jaws in number are formed in the rotary plate; the center of each arc-shaped groove deviates from that of the rotary plate; and the lower end of each clamping jaw is positioned in the corresponding arc-shaped groove. According to the connector provided with the rotary plate, the clamping jaws can rotate relative to the shaft lugs by rotating the rotary plate only, and the loading arm is stably connected with the tank truck, so that the automation level in the working process is high, the working process is safe and reliable, and the service life of each clamping jaw is prolonged.

Description

technical field [0001] The invention relates to a connector for connecting a crane pipe and a tanker, in particular, a connector that does not need to pull the claws by hand, but only needs to turn the turntable so that multiple claws can be rotated and opened synchronously relative to their corresponding axle lugs Or tightly locked on the tank car interface end to realize the stable connection between the crane tube and the tank car, which is used to connect the crane tube and the tank car. Background technique [0002] The loading and unloading truck transports media with high viscosity such as asphalt and oil, and generally chooses the bottom loading and unloading crane tube and adopts the bottom unloading method. Bottom loading and unloading crane pipe is composed of connecting flange, outer arm, swivel joint, outrigger (metal hose), connector and balance system for connecting crane pipe and tank car. The crane tube is connected with each other by 5 rotating joints to r...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure of the claw is slender and the strength is not enough, and it is easy to break when the stress on the pull is large;

[0005] 2. It is necessary to turn the screw and pull the claws by hand every time the truck is unloaded, which is cumbersome and inefficient;

[0006] 3. The claw used to connect the connector of the crane pipe and the tank car is unreliable in connection with the interface of the tank car. It may loosen when there is external vibration, etc., and the stability of the working process is low;

[0007] 4. After loading, there is residual liquid on the claws, which may be touched by manual operation, and the safety is low
