Description

A light agricultural lifting device

technical field

The utility model relates to a lifting device, in particular to a light agricultural lifting device, which belongs to the technical field of agricultural production.

Background technique

Since most rural households are buildings with 2-3 floors, although the roof of the building has good wind and light conditions as a drying place for grain, it is not only time-consuming and laborious to transport food to the roof of the building by manpower, but also accompanied by great danger. Seriously reduce the efficiency of agricultural production.

At present, construction cranes are usually used to lift grain, but the traditional construction lifting devices are large in size and weight, which are difficult to carry, and the horizontal extension distance of the boom is short, and the heavy swing is large during the hoisting process, which is easy to damage the wall or glass curtain wall, causing unnecessary damage. necessary loss.

Utility model content

Purpose of the utility model: The purpose of this utility model is to design a light-duty agricultural lifting device for the deficiencies of the prior art. Manpower and material resources consumption, improve agricultural production efficiency.

Technical solution: A light-duty agricultural lifting device described in the utility model includes an equipment base, a hoisting frame and a hoist system, and the hoisting frame and hoist system are fixed on the equipment base after being fixed by the boom base.

The boom is composed of two parts welded by a diagonal bar and a cross bar, and the supporting capacity is strengthened by a reinforcing bar. Fixed pulleys and guide pulleys are installed at the end of the cross bar and the cross bar and the diagonal bar. The hoist system includes a hoist drum, a hoist and Universal switch, one end of the wire rope is fixed on the boom cross bar, one end goes around the movable pulley, and is fixed on the hoist drum through the fixed pulley and the guide pulley at the end of the cross bar, and the suspension hook is installed on the movable pulley.

The hoist system is installed on the operating plate above the operating rod, fixed on the shell of the base of the boom through the balance arm, and is located in the opposite direction of the boom.

The boom base shell is sleeved on the boom base, and balls are installed between the two, so that the hoisting frame and hoist system fixed on the boom shell can rotate around the boom base.

The boom base is fixed above the equipment base through four brackets. The equipment base is made of hollow iron pipes, which can be inserted into wooden sticks independently to extend the base, and the counterweight can be increased independently according to the quality of the lifting object.

Compared with the prior art, the utility model has the beneficial effects that the utility model has the advantages of simple structure, reasonable design, light equipment, convenient movement and disassembly, high operating efficiency and large lifting capacity, and is suitable for agricultural production activities and other lifting tasks that require lifting. the scene of the thing.

Detailed ways

Below in conjunction with accompanying drawing, the embodiment of the present utility model is described in detail: present embodiment is carried out under the premise with the technical scheme of the present utility model, has provided detailed embodiment and concrete operation process, but protection scope of the present utility model is not Limited to the following examples.

Embodiment: As shown in Figures 1 and 2, a light-duty agricultural lifting device includes an equipment base 1, a hoisting frame and a hoist system. After the hoisting frame and hoist system are fixed by the boom base shell 4, they are placed on the Arm base 5.

The equipment base 1 is welded by thick steel pipes, and the support 2 is made of 8# channel steel, which is used to support the boom base 5. When hoisting, a counterweight is independently applied to the equipment base 1, and the lifting objects can also be seen Quality, insert wooden sticks in the equipment base 1, extend the base to facilitate the increase of counterweight.

The boom base shell 4 is set on the boom base 5, and the ball string 3 is adopted in the middle to make the boom base shell 4 rotate around the boom base 5, which is convenient for hoisting and equipment disassembly.

The boom adopts 8# channel steel and is composed of inclined bar 6 and cross bar 7, and the supporting effect is strengthened by strengthening bar 8. The so-called strengthening bar is made of angle steel, welded on inclined bar 6 and cross bar 7, and one end of inclined bar 6 is welded On the boom base shell 4, one end is connected with the cross bar 7, a guide pulley 9 is installed at the welding place, and a fixed pulley 10 is installed at the other end of the cross bar. One end of the steel wire rope 11 is fixed on the boom cross bar 7, and one end is wound Overrunning pulley 12 is fixed on the hoist drum 17 through fixed pulley 10 and guide sheave 9 at cross bar 7 ends, and described suspension hook 13 is installed on the movable pulley.

The operating rod 15 is connected with the boom base shell through the balance arm 14, and is fixed in the opposite direction of the boom, and the connection between the balance arm 14 and the boom is strengthened by the pull rod 15, and the operating table 17 is fixed on the operating rod 16. The hoist and control switch are installed on the console.

When lifting heavy objects, the boom bar 7 stretches out of the floor, and the corresponding counterweight is set on the equipment base 1 to control the hoist 19 to reverse, so that the hook 13 is lowered with the pulley 12. After lifting the heavy object, the hoist 19 is controlled. Forward rotation, after hoisting the heavy object to a suitable height, the operator can hold the operating rod 16 and rotate to a suitable position and put it down to unload the heavy object.

As stated above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
