Abstract

The invention relates to a paper pulp lifting appliance, in particular to a lifting appliance which can automatically grab and release goods bound together. The invention belongs to the field of loading and unloading operation. The invention relates to an accessory which needs to be arranged on a host of engineering machinery such as a crane, a material grabbing machine and the like, and a series of loading and unloading operations such as grabbing, placing, loosening and binding together of goods are finished by remotely controlling a power system of a lifting appliance through a host driver. The operation of 'picking' and 'hanging' the lifting hook is not needed by extra workers, the investment of field personnel is reduced, the loading and unloading operation efficiency is improved, and the safety of field operation is improved. The lifting hook of hoist can the spacing of adjusting, and the adaptation snatchs not unidimensional goods. The lifting hook of the lifting appliance has enough opening range so as to easily grab the steel wire for binding the goods and reduce the operation difficulty.

Description

Paper pulp sling

Technical Field

The automatic loading and unloading lifting appliance can be used as an accessory of engineering machinery such as a crane or a material grabbing machine and the like, only a host driver 1 needs to operate, and cargoes bound together can be automatically loaded and unloaded through power modes such as gas, electricity, hydraulic pressure and the like.

Background

At present, the quantity of paper pulp taken in and out in ports in China is more and more, so the requirement on the efficiency of paper pulp packaging operation is higher and higher. In the operation of loading and unloading the paper pulp bags at the port in China, a common paper pulp lifting appliance needs two operators to carry out hooking and unhooking operations respectively, and in addition, one crane operator is needed and possibly a commander is also needed; there is also a pulp spreader with automatic unhooking function, but still needs an operator to do the hooking work. In conclusion, the loading and unloading operation is not only low in efficiency, but also high in labor intensity and danger of operators, and the labor cost is high. Therefore, in order to overcome the defects of low working efficiency and low personal safety of the existing paper pulp lifting appliance, the full-automatic loading and unloading special lifting appliance for paper pulp is developed.

The goods to be grabbed are not limited to pulp, and the goods can be automatically loaded and unloaded by the lifting appliance as long as the goods are bound together.

The existing lifting appliance needs manual loading and unloading, or needs manual 'hooking', and can only automatically finish 'unhooking'.

Disclosure of Invention

The invention relates to an accessory which needs to be arranged on engineering machinery hosts such as a crane, a material grabbing machine and the like to automatically grab and bind goods together. The lashed cargo is typically lashed together by steel wire. A typical cargo is a pulp bale.

The preferred embodiment of the present invention is a hard-link triple-pack autoloading spreader for binding cargo.

It mainly comprises the following parts: a frame 1, a rotary driving device 2, a lifting hook 3, an alignment seat 4 and the like.

The frame 1 is the main structural part of the spreader. The lifting appliance is formed by welding rectangular steel pipes 1.1, the size of the lifting appliance needs to be designed according to the size and the weight of goods, and a frame of the triple-pack lifting appliance is shown in figure 1. The middle part of the frame is provided with a reinforcing structure connected with the rotary driving device 2 so as to facilitate the smooth transfer of the cargo load.

The swing drive 2 is provided at an intermediate position of the frame 1. In the example, the slewing drive device 2 is a worm and gear type slewing bearing 2.2 driven by a hydraulic motor 2.1, the hydraulic motor 2.1 drives a worm, the worm drives an inner ring 2.2.1 of the slewing bearing with a worm wheel, the inner ring of the slewing device is connected with the frame 1, and the outer ring is fixed on a main machine, so that the whole lifting appliance is driven to perform slewing motion. Of course, other rotary drives may be used.

As shown in fig. 2, the lifting hook 3 completes the opening and closing of the lifting hook through the cylinder 3.1, and only a driver of a crane or a material grabbing machine needs to carry out remote operation, and infinite extra personnel carry out short-distance operation. Of course, an actuating mechanism such as a hydraulic cylinder or an electric cylinder can be selected to complete the opening and closing of the lifting hook.

When the lifting hook is opened, the lifting hook is opened to form a certain opening, and the opening of the lifting hook falls into the range of the binding rope through the operation of a driver of the host; at the moment, the driver operates the lifting hook to complete the closing action, and the binding rope is grabbed into the lifting hook. The process can be operated by only one person of a driver to complete the cargo grabbing action.

The aligning seat 4 is connected with the shaft 3.2 on the hook 3. The alignment seat 4 is adjusted in position by the base 1.1 in order to accommodate different sizes of goods.

Dovetail plates 5 are arranged on the frames at both sides of the lifting hook 2. The dovetail plate 5 is fixed to the base 1.3 welded to the frame 1 using fasteners, which have the main function: firstly gather together the steel wire of comparison dispersion, make the lifting hook of opening more conveniently snatch the steel wire, secondly make things convenient for the host computer driver to observe, play the effect of direction.

Four support tubes 6 are also provided on the frame 1. The support tube 6 is fixed to the base 1.2 welded to the frame 1 using fasteners, which have the main function: firstly, the hoist of being convenient for stands on the goods of binding to keep the certain distance with the goods, the lifting hook of being convenient for snatchs, secondly the hoist time spent not, depositing of the hoist of being convenient for.

4 lifting lugs 1.4 are also arranged on the frame 1 and are mainly used for transferring a lifting appliance. And cannot be used to lift cargo.

As shown in fig. 3, there is another proposal of a flexible-connection four-pack automatic loading and unloading spreader for binding cargoes, which connects a wire rope or a sling through 4 lifting eyes 2 on a frame 1, and fixes the wire rope or a lifting point on a lifting hook of a crane through a lifting component such as a shackle.

Through adjusting plate 3 and adjusting plate 4, the hoist driver operates the quadruple package hoist, touches the goods, makes the hoist correctly pendulum put the goods below. The remaining similar components are in accordance with the preferred embodiments.

Description of the drawings: FIG. 1 is a view of the gripper in an expanded state; FIG. 2 is a view showing a closed gripping state of the gripper; fig. 3 is a combined working state diagram of 4 sets of grippers.

Claims

1. A lifting appliance capable of being automatically assembled and disassembled does not need manual operation of 'picking' and 'hanging' lifting hooks, reduces the investment of field personnel, improves the assembling and disassembling operation efficiency and improves the safety of field operation.

2. The positions of the hook installation positions are adjusted to adapt to cargoes of different sizes and bundled together.
