Description

Movable small-sized hanger rod

Technical Field

The utility model relates to a portable small-size jib of easy installation and dismantlement comprises base and two parts of main part, and the base part is erect and is fixed at the operation scene, and the main part can be dismantled and remove.

Background

Large bulk carriers usually rely on only berthing modernized professional docks, use high-efficiency specialized onshore loading and unloading equipment for loading and unloading goods, and the cargo hatchway of large bulk carriers is generally not provided with a fixed boom, so that the lifting of garbage for cleaning cargo holds becomes a difficult problem. Open-air equipment on a ship deck is subjected to wind blowing, sun exposure and seawater erosion, and is extremely difficult to maintain. The situation that the large bulk cargo ship needs to hoist the garbage in the cargo hold rarely occurs, a fixed type suspender with extremely high maintenance cost is arranged at a cargo hatch only for hoisting the garbage in the cargo hold, so that the large bulk cargo ship is not economical, the large bulk cargo ship is suitable for hoisting the garbage in the cargo hold by using a movable type small suspender, and the large bulk cargo ship is moved into a storehouse to be properly kept when not used.

The existing various movable small-sized booms are not suitable for being used in the cargo hatch of a large-sized bulk cargo ship, and the main reason is that the bases of the existing various movable small-sized booms occupy too large space, various obstacles exist at the optimal position for placing the movable small-sized booms in the cargo hatch of the large-sized bulk cargo ship, and the bases of the existing various movable small-sized booms are not placed in enough space.

At present, most of large bulk cargo ships adopt an alternative method to solve the problem of lifting the garbage in the cargo hold, and the method for lifting the garbage in the cargo hold by using the power of a cable winch at the bow or the stern is as follows: a bent rod extending to a cargo hold is arranged at a proper position of a cargo hold opening, a guide pulley is arranged at the top of the bent rod, a guide pulley is also arranged at a proper position on a deck, a cargo lifting rope is guided to a cable winch at the bow or stern of the ship through the guide pulleys, the cargo hold garbage can is lifted to be above the opening surface of the cargo hold by using the power of the cable winch, then the cargo lifting rope is loosened, the garbage can is pulled out of the cargo hold manually, the lifting weight is a little bit, the garbage can is difficult to pull out of the cargo hold manually, and therefore the lifting weight is limited every time, and the working efficiency is low. The distance of the cable winch is far, multiple persons are needed to cooperate, and once the cable winch is not matched with the cable winch, if the garbage can rises to the top and is not stopped twisting in time, the lifting cable is easy to break and the cable is easy to burst, so that industrial accidents are caused.

Disclosure of Invention

The utility model provides a base accounts for the space too big in order to overcome the base of current various portable small-size jibs, and there are various barriers in the best position that large-scale bulk cargo ship cargo hatch door put portable small-size jib, does not have enough space to put the base of portable small-size jib, therefore current various portable small-size jibs all are not fit for using at large-scale bulk cargo ship cargo hatch door, adopt alternative handling cargo hold rubbish inefficiency and easily cause the hanging cargo cable to stretch out, the rigging bursts to cause this difficulty of industrial accident, the utility model provides an easy portable small-size jib of installation and dismantlement, its base is fixed at the operation scene, and the main part can be removed.

The utility model provides a technical scheme that its technical problem adopted is: the movable small suspender comprises a base and a main body, wherein the base comprises a base barrel and a lock rod, the main body comprises a vertical barrel, a main rod and an auxiliary rod to form a triangular structure, a front guide pulley is arranged at the front end of the main rod, a rear guide pulley is arranged at the rear end of the main rod, a hoisting frame is connected to the rear side below the vertical barrel, a hoisting machine is arranged on the hoisting machine frame, a needle roller bearing is arranged at the upper end of the vertical barrel, and a hoisting rope on the hoisting machine passes through the rear guide pulley and the front guide pulley and then is connected with a lifting hook. A fixed base cylinder is vertically arranged at a proper position of a cargo hatch of a large bulk cargo ship, when a main body part is installed and used, a locking rod is inserted into the base cylinder from bottom to top and then inserted into a vertical cylinder of the main body part, the top end of the locking rod is inserted into a ball bearing, a movable small suspender base and the movable small suspender main body part are connected in series, and the locking rod becomes a rotating shaft for the horizontal rotation of the suspender main body part.

The utility model has the advantages that: the movable small suspender comprises a base and a main body, wherein a vertical cylinder of the base part is vertically fixed at a proper position of a cargo hatch of a large bulk cargo ship, the vertical cylinder is simple in structure and easy to maintain, the main body part can be rapidly installed and detached, and the main body part which is complex in structure and difficult to maintain can be moved into a storehouse to be properly kept when not in use, so that air blowing, solarization and seawater erosion are avoided.
