Abstract

The utility model relates to a hoisting and fixing device of a marine instrument for conducting sea test and oceanographic survey, in particular to a vertical shaft working platform device for a ship-borne marine instrument. The working platform comprises a vertical shaft, a guide rail on the vertical shaft and a stop ring at the lower end of the guide rail and is characterized by also comprising a suspension cage and three ejector rods fixed on the ejector rod base, wherein the suspension cage consists of an ejector rod base on an upper fixed disk, a flying ring and a lower fixed disk; the other end of the ejector rod is connected with a locking nut and fixed on a shaft cover that is fixed at the upper end of the vertical shaft by a bolt; a steel cable is connected with the flying ring and connected on a crane through a fixed pulley to hang the suspension cage; and the outer edges of the upper fixed disk and the lower fixed disk are respectively provided with a guide slot. The lower part of the guide rail forms a wedge surface to be clamped on the suspension cage, thus stopping the suspension cage from moving. The working platform device is convenient for assembly and disassembly of the marine instrument, simple and convenient in operation, high in reliability and going to play a huge role in the marine instrument test and marine survey of China.

Description

Vertical shaft working platform device for shipborne oceanographic instrument

Technical field

The utility model relates to a kind of lifting anchor fitting that carries out the oceanographic instrumentation of sea test and oceanographic survey, is specifically related to a kind of vertical shaft working platform device for shipborne oceanographic instrument.

Background technology

The marine acoustics instrument installation requirement condition that is used for sea test and oceanographic survey is very harsh, must be installed in hull bottom, general boats and ships are difficult to reach, unless advancing dock ad hoc loads and unloads, and this need spend expensive expense, and in process of the test, often need instrument and equipment to be debugged and keeped in repair temporarily, very inconvenient.Therefore need a kind of platform that oceanographic instrumentation equipment is installed especially.

Summary of the invention

The purpose of this utility model provides a kind of vertical shaft working platform device for shipborne oceanographic instrument, to remedy the deficiencies in the prior art.

The utility model comprise vertical shaft and on guide rail and the stop ring of guide rail lower end, it is characterized in that it also comprises the cage that is made of push rod base, suspension ring and lower fixed disk on the last reaction plate, three push rods that are fixed on the push rod base, the other end of push rod connects jam nut and is fixed on the well lid, well lid is to be bolted to the vertical shaft upper end, wirerope connects suspension ring, is connected through fixed pulley and hangs cage on the crane, has guide groove on the outer of last reaction plate and lower fixed disk.

The bottom of above-mentioned guide rail is wedge surface and stops cage to move on the cage to be stuck in.

The utility model is convenient to the oceanographic instrumentation Assembly ﹠Disassembly, and is easy and simple to handle, and the reliability height will be played a great role for the test of China oceanographic instrumentation and oceanographic survey.

Description of drawings

Fig. 1 is the utility model overall structure.

Wherein: 1, crane; 2, wirerope; 3, fixed pulley; 4, jam nut; 5, bolt; 6, well lid; 7, push rod; 8, vertical shaft (borehole wall); 9, guide rail; 10, stop ring; 11, cage; 12 push rod bases; 13, go up reaction plate; 14, lower fixed disk; 15, suspension ring; 16, guide groove.

The specific embodiment

As Fig. 1, the utility model comprise vertical shaft 8 and on guide rail 9 and the stop ring 10 of guide rail 9 lower ends, it is characterized in that it also comprises the cage 11 that is made of the push rod base 12 on the last reaction plate 13, suspension ring 15 and lower fixed disk 14, three push rods 7 that are fixed on the push rod base 12, the other end of push rod 7 connects jam nut 4 and is fixed on the well lid 6, well lid 6 is fixed on vertical shaft 8 upper ends with bolt 5, wirerope 2 connects suspension ring 15, be connected through fixed pulley 3 and hang cage 11 on the crane 1, have guide groove 16 on the outer of last reaction plate 13 and lower fixed disk 14.

The bottom of above-mentioned guide rail 9 is wedge surface and stops cage 11 to move on the cage 11 to be stuck in.

The utility model is arranged near the hull line of centers, and it is less to wave angle herein, and the space is bigger in the cabin, is convenient to the installation and the debugging of instrument and equipment.

During use, with the test the marine acoustics instrument or the oceanographic survey instrument and equipment be fixed on cage lower fixed disk 14 on, with crane 1 and wirerope 2 by fixed pulley 3 cage 11 put into vertical shaft the borehole wall 8 (because of the weight of cage 11 and instrument greater than 40kg), require cage guide groove 16 to align with directed guide rail 9 before putting into to determine the direction of cage 11, when cage 11 be put into cage stop ring 10 above the time, wirerope 2 can not relaxed the effect of holding cage 11.Cage stop ring 10 is held cage 11 at this moment, the instrument lower end on the cage 11 parallel with inner bottom hull (prevention is hung instrument and equipment by fishing net during navigation).Use push rod 7 according to the male and female head then, be inserted on the push rod base 12, be inserted in the square groove of following push rod 7 with another root push rod 7 again, uppermost push rod 7 is turned round upper locking nut 4, jam nut 4 is rotated to the inner end (clickwise) of push rod 7 screw threads, cover well lid 6, it is fixing to tighten well lid bolt 5, at last jam nut 4 is up rotated (inhour rotation).Cage 11 dieback (running into severe sea condition can not become flexible yet) on the borehole wall 8 of stop ring 10 and vertical shaft firmly, make the cage 11 and the borehole wall 8 of hull vertical shaft form whole with the inclined-plane, lower end of jam nut 4, push rod 7 and guide rail 9.

By sea test, the utility model has reached designing requirement, for huge effect has been brought into play in the test of China marine acoustics and oceanographic survey.
