Description
Technical field
The present invention relates to a kind of Lifting Pipe in Deep Sea Mining equipment, and in particular to a kind of Lifting Pipe in Deep Sea Mining heave compensation dress
It sets.
Background technology
In deepsea mining system, since the influence ore-raising pipe of wave is easy to generate periodically heave fortune with wave
It is dynamic, when mining activity carries out, ore-raising pipe not only will intermediate ore storage bin walking in tow, still suffer from that heave movement brings huge bears
Lotus；This is easy to that ore-raising pipe is made to damage, and in turn results in great economic loss.
Current existing Lifting Pipe in Deep Sea Mining heave compensator constructs complicated, cost of equipment maintenance height mostly；With
The foundation of social progress and conservation-minded society, it is desirable that we economize on resources and reduce as far as possible resource consumption, and obtain maximum
Economy and community income；Want to solve the problems, such as this, it is very necessary to design a kind of Lifting Pipe in Deep Sea Mining heave compensator
's.
Invention content
The object of the present invention is to provide a kind of Lifting Pipe in Deep Sea Mining heave compensators, it is intended to preferably realize that deep-sea is adopted
Mine ore-raising pipe heave compensation.
The invention is realized by the following technical scheme：
A kind of Lifting Pipe in Deep Sea Mining heave compensator, including upper fixed cover, lower fixed cover, upper hydraulic cylinder, lower hydraulic pressure
Cylinder and spring；Upper fixed cover and lower fixed cover are equipped with ore-raising pipe mounting hole, and upper hydraulic cylinder cylinder body end is arranged in upper fixed cover, under
Hydraulic cylinder body end is in lower fixed cover, by rotating low pair even between upper hydraulic cylinder piston rod end and lower hydraulic cylinder piston rod end
It connects, more than one spring is set between upper fixed cover and lower fixed cover.
It is above-mentioned state Lifting Pipe in Deep Sea Mining heave compensator on the basis of, upper hydraulic cylinder cylinder body end by upper fixed pin and on
Mounting base is arranged in upper fixed cover, and lower hydraulic cylinder body end is arranged by lower fixed pin and lower mounting seat in lower fixed cover,
Pass through flexural pivot chain link between upper hydraulic cylinder and lower hydraulic cylinder.
It is above-mentioned state Lifting Pipe in Deep Sea Mining heave compensator on the basis of, upper fixed cover, lower fixed cover offside be arranged two groups
Anti- magnetic is to permanent magnet.
It is above-mentioned state Lifting Pipe in Deep Sea Mining heave compensator on the basis of, between upper fixed cover, lower fixed cover be arranged two
Compressed spring.
The advantage of the invention is that：It is realized and is connected by spherical hinge between upper hydraulic cylinder and lower hydraulic cylinder, it can be better
Realize heave compensation function.Equipped with a pair of of compressed spring between upper fixed cover, lower fixed cover, plays heave compensation and obtain auxiliary work
With.

Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
With reference to figure 1, a kind of Lifting Pipe in Deep Sea Mining heave compensator, including upper fixed cover 1, lower fixed cover 2, upper hydraulic pressure
Cylinder 3, lower hydraulic cylinder 4 and spring；Upper fixed cover 1 and lower fixed cover 2 are equipped with ore-raising pipe mounting hole 9, the setting of 3 cylinder body end of upper hydraulic cylinder
In upper fixed cover 1, lower 4 cylinder body end of hydraulic cylinder is in lower fixed cover 2,3 tailpiece of the piston rod of upper hydraulic cylinder and lower 4 piston rod of hydraulic cylinder
By rotating low secondary connection between end, more than one spring is set between upper fixed cover 1 and lower fixed cover 2.
3 cylinder body end of upper hydraulic cylinder is arranged by upper fixed pin 12 and upper mounting seat 11 in upper fixed cover 1, lower hydraulic cylinder 4
Cylinder body end is arranged by lower fixed pin 7 and lower mounting seat 10 in lower fixed cover 2, passes through between upper hydraulic cylinder 3 and lower hydraulic cylinder 4
Flexural pivot chain link.
Two groups of anti-magnetic are arranged to permanent magnet 5 in upper fixed cover 1,2 offside of lower fixed cover, fixed cover 1 and lower fixed cover 2 in realizations
Between keep certain distance, and a part of heave movement can be resisted.
Two compressed springs 6 are set between upper fixed cover 1, lower fixed cover 2, plays heave compensation and obtains booster action.
It is as follows using the course of work of the present invention:8 upper port of ore-raising pipe is fixed on fixed cover 1, when ore-raising pipe 8 with wave into
When row heave movement, which is transmitted to 3 one end of upper hydraulic cylinder by upper fixed cover 1, and a part of heave is compensated by hydraulic cylinder 3
Movement, upper hydraulic cylinder 3 are fixed on by fixed pin 7 in upper fixed cover 1, pass through spherical hinge between upper hydraulic cylinder 3 and lower hydraulic cylinder 4
Realize connection, when ore-raising pipe 8 carries out heave movement with wave, upper hydraulic cylinder 3 can be collapsed with lower hydraulic cylinder 4, be opened, this
Design can also compensate a part of heave movement.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
