Problems solved by technology

It includes a column set up and down. The column is divided into upper and lower sections. The upper column and the lower column are connected to each other. The bottom of the lower column is fixed to the vehicle. The front end of the lifting arm is connected with a telescopic lifting connection device and a fixed lifting connection device, and a telescopic manual hydraulic cylinder is connected between the upper column and the lifting arm. The telescopic lifting connection device is a lifting rope and The hand hoisting device with a winch connected to it; this kind of crane can solve the problem of manual loading and unloading, but since this kind of crane is fixed on the car, obviously, the loading capacity of each car is limited, when it needs When transporting a large number of products, multiple trucks equipped with such cranes are required to complete the mechanical loading and unloading. Otherwise, manual loading and unloading is still required, and the limitations are very obvious; in view of this, the inventor aims at the current problems. Portable Universal Crane

Embodiment 1

[0039] see Figure 1 to Figure 16, a portable general-purpose crane, including a lifting device 1; the lifting device 1 includes a rotatable swivel 2, a hanging beam 3, a steel rope 13 and a drive mechanism 4 for retracting and retracting the steel rope 13, the hanging beam The lower end of the 3 is connected with the swivel 2, the upper end of the suspension beam 3 is provided with a first fixed pulley 11, one end of the steel rope 13 is connected to the driving mechanism 4, and the other end of the steel rope 13 passes through the first fixed pulley. The pulley 11 is also connected with a hook 14 for hanging goods; at the same time, in order to reduce the load of the lifting device 1, the hanging beam 3 is also provided with a second fixed pulley 12 for the steel rope 13 to pass through, and also includes a rotating Seat 5, the upper end of the swivel seat 5 is rotatably connected to the swivel body 2, and the lower end of the swivel seat 5 is provided with a chassis 51 for ...

Embodiment 2

[0051] At present, the longitudinal beams of the truck chassis are generally made of two types of steel, one is "U"-shaped steel (see Figure 16 ), the other is "I" steel (see details Figure 20 ), when the truck underframe is made of "U"-shaped steel, the horizontal bracket 6 of Embodiment 1 can be fixedly connected with the truck underframe of "U"-shaped steel; the purpose of this embodiment is to: In order to make the crane At the same time, it can also adapt to the trucks produced by "I" steel materials, combined with Figure 17 to Figure 20 The difference between this embodiment and Embodiment 1 is that an adjusting screw 909 is arranged on the lower part of the elongated frame 901, and a screw sleeve 910 is movably connected to the outside of the adjusting screw 909, and the lower end of the screw sleeve 910 is set There is a first collet 911 provided with a first jackscrew 912 for a solid connection. During use, the first chuck 911 is clamped on the bottom of the "I" st...

Abstract

The invention relates to the technical field of loading and unloading devices, and discloses a portable universal crane. During the use, the crane is placed beside a vehicle to be subjected to goods loading or unloading, a chassis is lowered to be supported on the ground, and then, a transverse bracket is opened to extend into an underframe of the vehicle for propping and fixing, so that the loading and unloading of goods can be implemented; during the mounting process, the assembling and disassembling of crane and the goods loading and unloading can be completed by a single person, so that manpower is greatly saved; when the goods loading and unloading of one vehicle is completed, the transverse bracket is loosened and taken down from the lorry underframe, and the crane is mounted on another vehicle required to be subjected to loading and unloading, so that the whole transport vehicle team only needs to be equipped with only one crane to complete the goods loading and unloading; the crane has higher universality, can be used for completing the assembling and disassembling quickly by a single person, can be transported along with vehicles, has high portability, and is excellent in applicability as the crane can be used in mountainous areas, plain or hill areas as long as vehicles are used.

Description

technical field [0001] The invention relates to the technical field of loading and unloading equipment, in particular to a portable universal crane. Background technique [0002] At present, with the continuous progress of the social economy, the industrial economy is becoming more and more obvious. According to the advantages and characteristics of the region, a manufacturing base is established to produce various products, and then different products are distributed to the demand places through logistics. In the process of decentralization, a large number of The products are transported in the form of containers, etc. Generally, the gantry cranes or lifting equipment installed at the port or freight station can be used for loading and unloading. However, when there are some individual products with large shapes, such as emergency boats for emergency use And sports kayaks, etc., when people often transport such products, due to limited conditions, they are usually transport...
