Abstract

The invention provides a marine telescopic crane which is simple in structure and convenient to operate, can realize flexible lifting, is suitable for the lifting working conditions of different working radiuses, effectively avoids the phenomenon that a steel wire rope deviates and jumps out of a groove, improves the working efficiency and the use safety, and has high use and popularization values. The marine telescopic crane comprises a base fixed on a deck, wherein a tower body is mounted on the base through a slewing bearing; a basic boom is hinged to one side of the top of the tower body; a hydraulic winch is mounted at the upper end of the basic boom; a telescopic boom is mounted in the basic boom; a pulley device is mounted at the end part of the telescopic boom; one end of the steel wire rope is connected with the hydraulic winch; the other end of the steel wire rope bypasses the pulley device and is connected with a lifting hook; a first fixing piece is arranged on one side of the lower part of the tower body; a second fixing piece is arranged at the bottom of the basic boom; and a derricking oil cylinder is mounted between the first fixing piece and the second fixing piece.

Description

Telescopic crane for ship

Technical field

The present invention relates to technical field of crane equipment, be specially Telescopic crane for ship.

Background technology

Ship's crane, is a kind of big deck machinery on ship, and it is the equipment of a kind of ship loading and unloading goods. The Universal hydraulic crane being arranged on towboat is primarily used to lifting the articles for daily use and rubbish incidental, and the crane aboard ship equipped, often there is the hoisting operation operating mode of different operating radius, particularly in medium and small-scale vessel not being particularly convenient for goods jack, simultaneously in lifting work process, owing to crane ship and taken-over vessel can with wave pitching, rolling and heaves, these motions will cause that load swings, thus cause steel wire rope sideslip, de-groove phenomenon and make crane cannot normal operation, affect work efficiency.

Summary of the invention

For the problems referred to above, the invention provides Telescopic crane for ship, its simple in construction, easy to operate, flexible lifting can be realized, be suitable for the lifting operating mode of different operating radius, and be prevented effectively from the phenomenon of steel wire rope sideslip, de-groove, improve work efficiency and safety in utilization, have and use promotional value preferably.

Its technical scheme is such that its base including being fixed on deck, it is characterized in that: described base is provided with tower body by pivoting support, the top side being positioned at described tower body is hinged with basic arm, the upper end of described basic arm is provided with hydraulic wireline winch, telescopic telescopic arm is installed in described basic arm, the end of described telescopic arm is provided with tackle arrangement, one end of steel wire rope is connected with described hydraulic wireline winch, the other end described pulley gear connecting shackle of traverse of described steel wire rope, the side, bottom of described tower body is provided with the first fixture, the bottom of described basic arm is provided with the second fixture, described first fixture, between second fixture, amplitude oil cylinder is installed.

It is further characterized by described tackle arrangement and includes pulley, described steel wire rope it is wound with in the pulley groove of described pulley, baffle plate is fixed between the support of described pulley both sides, described baffle plate inner surface is provided with rib, fixing plate it is equipped with between described pulley and two side stands, described fixing plate one end is fixed through described rib and described baffle plate, the described fixing plate other end is connected to described pulley afterbody, and the gap thickness between described fixing plate and the described pulley of both sides is less than the diameter thickness of described steel wire rope; Described rib scribbles grease.

The invention has the beneficial effects as follows, pass through telescopic arm, can conveniently realize the lifting operating mode of different operating radius, after fulfiling assignment, telescopic arm is reduced in basic arm, not only optimize crane configuration, and take less deck, realize various engineering operation, and rib is set at the baffle plate inner surface of tackle arrangement, the intensity of baffle plate can be improved, fixing plate it is equipped with between pulley and two side stands, then at pulley, fixing formation cavity between plate and rib, steel wire rope can swing wherein, gap thickness between fixing plate and the pulley of both sides is less than the diameter thickness of steel wire rope, avoid steel wire rope sideslip, the problem of de-groove, rib scribbles grease, prevent abrasion steel wire rope, and play good lubrication.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention;

Fig. 2 is the structural representation of tackle arrangement.

Detailed description of the invention

Such as Fig. 1, shown in Fig. 2, the present invention includes the base 1 being fixed on deck, base 1 is provided with tower body 3 by pivoting support 2, the top side being positioned at tower body 3 is hinged with basic arm 4, the upper end of basic arm 4 is provided with hydraulic wireline winch 5, telescopic telescopic arm 6 is installed in basic arm 4, the end of telescopic arm 6 is provided with tackle arrangement 7, one end of steel wire rope 8 is connected with hydraulic wireline winch 5, other end traverse pulley gear 7 connecting shackle 9 of steel wire rope 8, the side, bottom of tower body 3 is provided with the first fixture 10, the bottom of basic arm 4 is provided with the second fixture 11, first fixture 10, between second fixture 11, amplitude oil cylinder 12 is installed, by flexible telescopic arm 6, the lifting operating mode of different operating radius can be realized, after fulfiling assignment, telescopic arm 6 is reduced in basic arm 4, not only optimize crane configuration, and take less deck, realize various engineering operation, tackle arrangement 7 includes pulley 13, it is wound with steel wire rope 8 in the pulley groove 14 of pulley 13, baffle plate 15 is fixed between the support 16 of pulley 13 both sides, baffle plate 15 inner surface is provided with rib 17, the intensity of baffle plate 15 can be improved, it is equipped with fixing plate 18 between pulley 13 and two side stands 16, fixing plate 18 one end is fixed through rib 17 with baffle plate 15, fixing plate 18 other end is connected to pulley 13 afterbody, then at pulley 13, fixing formation cavity between plate 18 and rib 17, steel wire rope 8 can swing wherein, gap thickness between fixing plate 18 and the pulley 13 of both sides is less than the diameter thickness of steel wire rope 8, avoid steel wire rope 8 sideslip, the problem of de-groove, rib 17 scribbles grease, it is prevented that abrasion steel wire rope, and play good lubrication.
