Problems solved by technology

[0003] At present, in the lifting system of underwater robots, most of the flip-type locking mechanisms driven by interlocking oil cylinders are used. On the one hand, this type of locking mechanism has a large longitudinal Large, so that the size of the A-frame structure in the lifting system will increase accordingly, which will not only increase the weight of the entire lifting system, but also make the stress condition of the lifting system worse

Embodiment 1

[0018] Embodiment 1: as figure 1 , figure 2 As shown, the present invention includes an upper connection plate 1, a lower connection plate 2, a limit guide rail 8, a lock bolt 3 and an interlocking oil cylinder 5, and a connection support plate 7 is arranged between the upper and lower connection plates, and the inner sides of the two support plates 7 are symmetrically provided with limiters. Two guide rails 8 are symmetrically provided with sliding lock bolts 3, the sliding direction of the lock bolts 3 is parallel to the axis of the guide rails 8, and the outer ends of the two lock bolts 3 are respectively connected with interlocking oil cylinders 5, and the upper and lower connection plates Both are provided with round holes matched with the pre-locking parts.

[0019] Such as image 3 , Figure 4 As shown, one end of the lock bolt 3 is a lug 9, the other end is a semicircular hole 11 matched with the pre-locking part, and its upper end surface has a semicircular slope ...

Embodiment 2

[0023] Embodiment 2: The overall structure of this example is the same as that of Embodiment 1, the difference is that the range of the included angle α between the upper slope 10 of the locking bolt 3 and the horizontal plane in this example is 10°, and the upper cone of the pre-clamping member mushroom head 14 The lower surface is inwardly processed into a matching 10° angle.

Embodiment 3

[0024] Embodiment 3: The overall structure of this example is the same as that of Embodiment 1, the difference is that the range of the included angle α between the upper slope 10 of the locking bolt 3 and the horizontal plane in this example is 20°, and the upper cone of the mushroom head 14 of the pre-clamping part The lower surface is inwardly processed into a matching 20° angle.

Abstract

The invention relates to a locking mechanism used for an underwater robot suspending system, comprising an upper connecting plate, a lower connecting plate, spacing guide rails, a lock bolt and an interlocking cylinder, wherein, a connecting support plate is arranged between the upper connecting plate and the lower connecting plate; the two supporting plates are symmetrically provided with the spacing guide rails; the two guide rails are respectively provided with a glide lock bolt symmetrically; the gliding direction of the lock bolts is parallel to a guide rail axis; the external end parts of the two lock bolts are respectively connected with the interlocking cylinder; and the upper connecting plate and the lower connecting plate are respectively provided with a circular matched with a prelocking component. The locking mechanism of the invention drives the lock bolt to glide along the spacing guide rail through the cylinder, and changes the ordinary overturn of the interlocking and unlocking actions of the lock bolts into slide by utilizing a mushroom head of a locking underwater robot, thus saving the longitudinal dimension space, compressing the dimensions of the interlocking mechanism and the whole structure of the suspending system, lightening self weight and correspondingly improving the stress state; the end face of the lock bolt is an inclined face matched with the contact face of the prelocking component; the contact area is increased to lead the locking mechanism to have self locking function, the carrying capacity of the locking mechanism is improved, and the operation of the locking mechanism is more stable, safer and more reliable.

Description

technical field [0001] The invention relates to a locking mechanism, which is suitable for an underwater robot hoisting system. Background technique [0002] There are two main functions of the cable remote control underwater robot (ROV) lifting system: during the process of releasing the ROV, the ROV is lifted from the deck of the mother ship to the water surface, and then the ROV enters the water to execute the corresponding operation procedures; the ROV completes the operation procedures Finally, the hoisting system hoists the ROV from the water surface to the deck of the mother ship to complete the recovery process of the ROV. Wherein there is an important mechanism in the hoisting system, that is, the lock bolt locking mechanism. The function of the locking mechanism is to interlock the ROV (including the repeater) with the hoisting system during the release and recovery of the ROV. [0003] At present, in the lifting system of underwater robots, most of the flip-type...
