Problems solved by technology

[0004] In order to solve the deficiencies in the prior art, the disclosure provides a hydraulic locking device and locking method for the tailgate of a tank-type vehicle. A hydraulic system with high reliability is used to control the locking of the tailgate, and the tailgate and the tank are completed through the expansion and contraction of the oil cylinder. The locking between the body realizes the fast and efficient locking of the tailgate and the tank body, reducing the leakage caused by uneven locking

Embodiment 1

[0042] Such as Figure 1-7 As shown, Embodiment 1 of the present disclosure provides a hydraulic locking device for a tank-type vehicle tailgate, including a tank body 13, a tailgate head 10, locking rings (4, 8) and an oil cylinder 6, and the tank body 13 A tank body ring plate 14 is fixed at the tail, and a head flange ring plate 9 matching with the tank body ring plate 14 is fixed on the tailgate head 10; the locking ring (4, 8) includes a first lock The tightening ring 4 and the second locking ring 8, one end of the first locking ring 4 and the second locking ring 8 are symmetrically and rotatably fixed on the annular side of the head flange ring plate 9, the first locking The other end of the tight ring 4 is connected to one end of the oil cylinder 6, the other end of the second lock ring 8 is connected to the other end of the oil cylinder 6, and the inner surfaces of the first lock ring 4 and the second lock ring 8 are respectively provided with The matching groove of t...

Embodiment 2

[0055] Such as Figure 8 As shown, Embodiment 2 of the present disclosure provides a locking method;

[0056] Using the hydraulic locking device for the tailgate of the tank type vehicle described in the present disclosure, the steps are as follows:

[0057] Fit the tailgate head cover to the tail of the tank body, and make contact connections between the ring plate of the tank body and the flange ring plate of the head;

[0058] The cylinder rods at both ends of the hydraulic cylinder retract at the same time, and the first locking ring and the second locking ring move closer to the center of the tank body. After the cylinder rods at both ends are fully retracted, the first locking ring and the second locking ring lock the tank The body ring plate and the head flange ring plate are covered.

[0059] As some possible implementations, a compressible sealing ring is provided between the ring plate of the tank body and the flange ring plate of the head. During the locking proce...

Abstract

The invention provides a tank truck tail door hydraulic locking device and a locking method thereof. The tank truck tail door hydraulic locking device comprises a tank body, a tail door sealing head,locking rings and a hydraulic cylinder, a tank body annular plate is fixed to the tail part of the tank body, and a sealing head flange annular plate matched with the tank body annular plate is fixedto the tail door sealing head; the locking rings comprise a first locking ring and a second locking ring, one end of the first locking ring and one end of the second locking ring are both symmetrically and rotatably fixed to the annular side face of the sealing head flange annular plate, the other end of the first locking ring is connected with one end of the hydraulic cylinder, the other end of the second locking ring is connected with the other end of the hydraulic cylinder, and grooves matched with the tank body annular plate and the sealing head flange annular plate are formed in the innersurface of the first locking ring and the inner surface of the second locking ring correspondingly. Through expansion of the hydraulic cylinder, the tank body annular plate and the sealing head flange annular plate are opened and locked by the locking rings, a hydraulic system with the high reliability is used for controlling a tail door to be tightly locked, the tail door and the tank body are quickly and efficiently locked, and the leakage phenomenon caused by uneven locking is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of locking, in particular to a hydraulic locking device and a locking method for a tank-type tailgate. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] For tank vehicles with openable tailgates, it is necessary to lock the tailgate and the tank cover after use. The inventor found in the research that the traditional locking method is manual locking, and a wrench is required for manual locking. The tool uses the fulcrum lever principle to complete the locking; at the same time, in order to make the locking reliable, at least four manual locking mechanisms are required for the tailgate, and the force must be consistent when locking, otherwise there will be leakage at the unlocked part . Contents of the invention [0004] In order to solve the deficiencies in th...
