Description

Combined lifting system

Technical Field

The invention relates to the field of cargo loading baskets for hanging and transporting by a helicopter, in particular to a combined hoisting system.

Background

When the helicopter is used for hoisting and transporting, the loading basket is hung through the sling, and cargoes loaded in the loading basket are transported.

Disclosure of Invention

The invention aims to provide a combined hoisting system, which is a cargo transportation basket for hoisting and is used for loading cargos in the hoisting and transportation operation outside a helicopter.

The technical solution for realizing the purpose of the invention is as follows: the utility model provides a modular handling system, meshbelt cross-stitch makes the cross net as the protection network, and the collection dress board is placed on the protection network as the lower plate, installs four spinal branch supporting beams on the bottom plate four corners, and four entablature constitute the upper ledge security protection and form the cube framework on a supporting beam. The four sides of the cross-shaped net body are lifted upwards, and the edges of the four sides of the cross-shaped net body are fixed on the four sides of the upper frame to form a closed cubic hanging basket.

Compared with the prior art, the invention has the following remarkable advantages: the invention relates to a combined type cargo basket with a combined frame and a protective net, which can be quickly unfolded into a flat plate shape for loading, and large cargos can be directly loaded by a forklift. After loading, the blocks can be quickly combined into a cube shape for hoisting. The load in the vertical direction is born by the net body formed by sewing the mesh belts, and the net body can relatively uniformly distribute the load around through self deformation when the center of gravity of the cargo is not in the center of the bottom plate due to certain elongation of the mesh belts, so that the phenomenon of stress concentration can not occur. The framework and the protective screening can be separated, and the framework can be quickly decomposed into a plurality of slender steel beams for storage and transportation. The protective net can be used independently as a hoisting net and can be used for loading goods which are not afraid of extrusion.

Detailed Description

The invention is further described below with reference to the figures and examples.

A modular crane system is shown in figure 1. Mainly comprises a supporting beam 1, an upper cross beam 2, a right-angle joint 3, a collecting plate 4 and a collecting net 5.

The collecting plate is located at the center of the cross-shaped collecting net, four supporting beams are arranged on the collecting plate through quick-release pins at four corners of the collecting plate, the four upper cross beams form an upper frame through four right-angle joints, and the upper frame is placed in clamping grooves corresponding to the supporting beams to form a cubic frame. Four sides of the cross extension of the packaging net are respectively lifted and connected with the upper cross beam through the quick release mechanisms to form a cubic hanging basket, and four vertical sides of the hanging basket are mutually connected by the quick release mechanisms of the packaging net to form a closed structure.

When the device is used, the container net is firstly paved on the ground, the container plate is placed in the center of the container net, the four corners of the container plate are connected with the container net through the quick-release mechanisms, and the centering performance of the container plate is guaranteed as shown in figure 2. At this time, the operation of loading cargos can be carried out, and the large cargos can be directly loaded by a forklift or a crane.

The supporting beams are arranged at the four corners of the assembling plate through quick-release pins, as shown in figures 3 and 4.

The four upper cross beams form an upper frame through four right-angle joints as shown in figures 5 and 8. The two ends of the upper beam are provided with semicircular grooves, the right-angle joint is provided with a semicircular shaft, and the upper end of the semicircular shaft is provided with a knob as shown in figure 5. A spring is arranged between the lower end of the semicircular shaft and the right-angle joint shell, the upper half section of the semicircular shaft is flat, and a flat groove is arranged on the upper end face of the right-angle joint shell, as shown in fig. 6 and 7. Half round shaft is under the spring force effect in the draw-in groove of flat part embedding shell, and half round shaft is the unable rotation of lock-out state this moment, holds the knob and upwards mentions then half round shaft can rotate, has inserted the entablature and has lifted the knob behind the rotary joint and rotate the half round shaft in the right angle joint, makes the semicircle face card of axle go into the half slot of entablature, loosens in the flat part embedding draw-in groove of knob half round shaft can be under the spring force effect, accomplishes this moment and fixes, and the entablature can't be extracted. When the device is disassembled, the upper cross beam can be pulled out only by rotating the limit half shaft in the right-angle joint to enable the semicircular surface to rotate out of the semicircular groove. The upper frame is placed in the corresponding clamping grooves of the support beams to form a cubic frame, as shown in fig. 9. The four sides of the net body are lifted and connected with the hanging rings on the upper cross beam through the hooks as shown in fig. 10, and then the hooks on the sides of the integrated net are connected with the connecting rings to form a hoisting system as shown in fig. 11.
