Abstract

The utility model belongs to the technical field of hoisting equipment, and relates to a pneumatic hoisting cantilever, which includes a column. A first motor is installed on the top of the column. A cylinder is installed, the first pulley is set at the end of the piston rod of the cylinder, the second pulley and the third pulley are set at the upper end of the rotating arm, one end of the suspension rope is fixedly connected with the first pulley, and the other end of the suspension rope is reversed from the second pulley through the second pulley. Three pulleys lead downwards. The structure of the utility model is simple and reasonable, and the rotating arm can be rotated by multiple 360° through two rotating shafts. At the same time, the rotating arm can effectively expand the working radius. When not in use, the rotating arm can overlap with the horizontal plate, effectively saving space. ;In addition, the cylinder is lifted without using power, and the operation is economical.

Description

Pneumatic Lifting Jib

technical field

The utility model belongs to the technical field of lifting equipment and relates to a pneumatic lifting cantilever.

Background technique

Lifting heavy objects is a commonly used operation method in the production process. In the workshop, heavy objects can be lifted and shifted by driving. This lifting method saves time and effort, but for some objects weighing less than 500 kg, it can be lifted by driving. Lifting just seems to be economical and cost-effective, especially when there are many objects of this kind in the production workshop, and most of them need to be shifted, it is even more difficult to handle. This kind of object is difficult to move by manpower, and it is a headache for the staff during production.

Contents of the invention

In view of the above problems, the utility model provides a pneumatic lifting cantilever. The structure of the cantilever is simple and reasonable, and it can quickly and conveniently lift heavy objects within 500 kg during use. Effectively save space.

According to the technical solution of the present invention: a pneumatic lifting cantilever, which is characterized in that it includes a column, the top of the column is installed with a first motor, the output shaft of the first motor is fixedly connected with one end of the horizontal plate, and the other end of the horizontal plate is hinged to the rotating arm. A cylinder is installed on the arm, the first pulley is set at the end of the piston rod of the cylinder, the second pulley and the third pulley are set at the upper end of the rotating arm, one end of the suspension rope is fixedly connected with the first pulley, and the other end of the suspension rope is reversed through the second pulley. Lead down from the third pulley.

As a further improvement of the utility model, a second motor is installed on the outer end of the horizontal plate, and the output shaft of the second motor is fixedly connected to the rotary arm.

As a further improvement of the utility model, a base is fixed at the lower end of the column, and a rib plate is arranged between the base and the column.

The technical effect of the utility model lies in that the product structure of the utility model is simple and reasonable, and multiple 360° rotation operations of the rotary arm are realized through two rotating shafts. At the same time, the rotary arm also effectively expands the working radius. It overlaps with the horizontal plate, which effectively saves space; in addition, the cylinder lifts without using power, and the operation is economical.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.

In Fig. 1, it includes a column 1, a first motor 2, a horizontal plate 3, a second motor 4, a cylinder 5, a first pulley 6, a rotating arm 7, a second pulley 8, a third pulley 9, a suspension rope 10, and a workpiece 11 , Base 12, stiffener plate 13 and so on.

As shown in Figure 1, the utility model is a pneumatic lifting cantilever, including a column 1, a first motor 2 is installed on the top of the column 1, the output shaft of the first motor 2 is fixedly connected with one end of the horizontal plate 3, and the other end of the horizontal plate 3 is hinged Rotating arm 7, cylinder 5 is installed on the rotating arm 7, the piston rod end of cylinder 5 is provided with first pulley 6, the upper end of rotating arm 7 is provided with second pulley 8, the third pulley 9, and one end of suspension rope 10 is connected with first pulley 6. Fixedly connected, the other end of the suspension rope 10 is drawn downward from the third pulley 9 after the second pulley 8 reverses.

A second motor 4 is installed on the outer end of the horizontal plate 3 , and the output shaft of the second motor 4 is fixedly connected with the rotating arm 7 .

A base 12 is fixed at the lower end of the column 1 , and a rib plate 13 is arranged between the base 12 and the column 1 .

The working process of the utility model is as follows: according to the position of the workpiece 11 to be lifted, adjust the pivoting arm 7 to expand to a suitable position, and the adjustment action is completed by the first motor 2 and the second motor 4. After the pivoting arm 7 is adjusted in place, the cylinder 5 The piston rod of the cylinder 5 stretches out, and at this moment, the lifting rope 10 descends, and the workpiece to be lifted is fixed with the lifting rope 10, and the piston rod of the cylinder 5 is retracted.
