Description
Technical Field
The utility model relates to a maritime work platform and boats and ships field specifically are a maintenance loop wheel machine that is used for deck to assist to hang.
Background
The maritime work platform and the ship are provided with deck auxiliary cranes, and the deck auxiliary cranes are mainly used for lifting and supplying food, mechanical spare parts, lifting and dropping boats and the like.
Different from a heavy deck crane, the deck auxiliary crane has smaller lifting capacity and maximum working radius, is flexible to operate, and has much lower use cost, so almost all marine platforms and ships can be provided with the deck auxiliary crane.
As the deck auxiliary crane has higher use frequency, the maintenance and overhaul frequency is correspondingly increased, such as hoisting winches, rotary driving devices, luffing cylinders and other parts, and the easily damaged parts are all arranged above or near the cylinder of the crane, so that the maintenance and hoisting are difficult.
The traditional method is to assist the hoisting maintenance by means of a main deck heavy crane or by means of a crane on another auxiliary platform or vessel. The method has the disadvantages of wasting production resources, occupying operation time of a heavy crane or occupying a crane on an auxiliary platform or a ship, having high cost and even influencing production.
The utility model discloses mainly through designing a hoist and mount method, solve the deck and assist and hang maintenance hoist and mount problem.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a maintenance loop wheel machine that is used for deck to assist to hang.
The technical scheme of the utility model is that: the utility model provides a maintenance loop wheel machine for deck is assisted and is hung, including the davit, install in the base davit bottom, the base side is equipped with the base drum, base drum bottom is spherical recess, davit bottom top spherical structure inlays in base drum bottom recess, the glib talker is respectively designed to the upper and lower extreme on the base drum, be used for filling the grease, carry out fixed connection through gyration fixed pin between base drum and the davit, be equipped with the winch base on the davit side, install hand winch on the winch base, be connected with wire rope's one end on the hand winch, wire rope's the other end passes through the leading wheel and connects the lifting hook, the leading wheel is located the top of davit, be equipped with fixed lug on the davit lateral wall and be used for fixed lifting hook.
The utility model discloses an useful part: the utility model discloses a deck is assisted and is hung and provide a maintenance lifting device, can accomplish oneself and overhaul and maintain under the prerequisite that does not rely on heavy loop wheel machine in deck and auxiliary engineering ship.
Drawings
FIG. 1 is a general layout view of a maintenance crane of the present invention;
FIG. 2 is a schematic view of a base of the maintenance crane of the present invention;
wherein: 1. the device comprises a base, 2, a butter mouth, 3, a suspension arm, 4, a winch base, 5, a manual winch, 6, a steel wire rope, 7, a guide wheel, 8, a lifting hook, 9, a fixed lifting lug, 10, a rotary inhaul cable, 11, a rotary fixed pin, 12 and a base cylinder.
Detailed Description
In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.
As shown in figure 1, a maintenance crane for a deck auxiliary crane comprises a suspension arm, the bottom end of the suspension arm is arranged in a base, a base cylinder is arranged on the side surface of the base, the bottom end of the base cylinder 12 is a spherical groove, a spherical structure at the top end of the bottom of the suspension arm 2 is embedded in the groove at the bottom end of the base cylinder 12, so that friction during rotation can be reduced, a grease nipple 2 is respectively designed at the upper end and the lower end of the base cylinder 12 for filling grease and further reducing rotation friction, the base cylinder 12 and the suspension arm 3 are fixedly connected through a rotation fixing pin 11, when maintenance and hoisting are needed, the suspension arm is inserted into the base cylinder to hoist a part needing to be overhauled by the deck auxiliary crane, the operation is simple and convenient, a winch base 4 is arranged on the side edge of the suspension arm 3, a manual winch 5 is arranged on the winch base 4, one end of a steel, the guide wheel 7 is positioned at the top end of the suspension arm 3, the side wall of the suspension arm 3 is provided with a fixed lifting lug 9 for fixing a lifting hook 8, the middle part of the suspension arm is provided with a rotary inhaul cable 10, and the other end of the rotary inhaul cable is fixed at the top of the suspension arm.
When the lifting column is used for maintenance lifting operation, the lifting hook 8 is connected to equipment needing maintenance lifting, the steel wire rope 6 is recovered by the manual lifting winch 5, and the equipment is lifted to a proper height. Then, the boom is rotated by the rotation cable 10, the equipment is rotated to the above of the open space, the wire rope 6 is released by the hand winch 5, and the equipment is lowered to the deck surface. After the equipment is repaired, the equipment is hoisted to the installation position by using the hoisting column in a similar operation. When the davit was idle, fixed pin 11 can be fixed rotary motion, and lifting hook 8 can be fixed on fixed lug 9, prevents that the lifting hook from rocking.
