Description

Portable hoist

technical field

The utility model relates to a construction site tool in the electric power industry, in particular to a portable hoisting machine, which belongs to the field of power supply equipment.

Background technique

At present, when installing single pole smart switches, assembling transformer benches and other heavy objects in electric power construction, most of them use large equipment such as cranes to lift them, which consumes a lot of manpower and material resources, and increases labor and economic costs. Or in the working space such as the field, the crane can't enter the place to carry out construction operations. At this time, only the method of manual lifting is used, which is not only very low in efficiency, but also extremely inconvenient to operate.

Utility model content

According to the deficiencies in the prior art above, the problem to be solved by the utility model is: to provide a portable hoisting machine which is simple in structure, light in weight, compact in structure, easy to carry and operate, saves mechanical costs, and improves work efficiency.

The technical scheme that the utility model solves its technical problem adopts is:

The portable hoisting machine includes a pole, and a hoop is set at the bottom of the pole, and a cross arm is installed at a distance of 8000-12000mm from the hoop. One end of the cross arm is fixed on the pole through a connecting piece and a bolt, and the other end of the cross arm is passed through a flower basket. Screws and wire ropes are connected with the hoop, and a manual winch is installed on the cross arm, and an oil wire rope is wound on the manual winch, and the free end of the oil wire rope passes through the pulley fixed on the top of the pole and is connected to the lifting weight.

The portable hoisting machine is composed of a 1800-pound manual winch, a 25-meter oil wire rope, a 70*7*1500 cross arm, a hoop and a pulley, and is suitable for poles with a height of less than 15 meters and a lifting weight of less than 400 kilograms. lifting work. During the lifting process, the cross arm is fixed on the pole about 1 meter above the ground, and the hoop is fixed at the root of the pole through bolts. The cross arm and the hoop use a turnbuckle (cable buckle) and a wire rope as the device. The cable-stayed support is used to ensure the tension of the cross-arm. Hang the pulley at the firm support point on the top of the pole. The free end of the oil wire rope on the winch passes through the pulley and hangs the heavy object to be lifted. At the same time, the manual winch has an automatic brake function to prevent the heavy object from falling. With the help of this tool One person can operate the winch to lift the heavy object to the specified height.

Further preferably, the vertical distance between the hoop and the cross arm is 1000mm. Easy to install.

Further preferably, the connecting piece adopts angle steel, and the angle steel is fastened to the pole through bolts and cross arms. The length of the angle steel is greater than the diameter of the pole and less than the length of the cross arm. When in use, place the angle steel and the cross arm on both sides of the pole respectively, and connect the angle steel and the cross arm with bolts at both ends and fasten them on the pole. , It is easy to obtain materials, convenient to install and low in cost.

The beneficial effects that the utility model has are:

1. The portable hoist described above is small in size, light in weight, compact in structure, easy to carry and operate, and is suitable for narrow alleys, fields and other areas where large-scale motorized equipment cannot reach.

2. The portable lifting machine is easy to operate, and one person can complete the lifting work. The automatic braking function of the winch greatly improves the safety and stability of the operation.

3. The portable hoist described above can replace a crane to lift less than 400 kg in a narrow environment, which greatly saves mechanical costs and improves work efficiency.

Detailed ways

Embodiments of the utility model are further described below in conjunction with the accompanying drawings:

As shown in Figure 1, the portable hoisting machine described in the utility model includes a pole 1, a hoop 6 is arranged at the bottom of the pole 1, and a cross arm 3 is installed at a distance of 1000 mm from the hoop, and one end of the cross arm 3 passes through a connecting piece 4 and a bolt 5 is fixed on the electric pole 1, the other end of the cross arm 3 is connected with the hoop 6 through the turnbuckle screw 7 and the steel wire rope 8, the manual winch 9 is installed on the cross arm 3, and the oil silk rope 10 is wound on the manual winch 9, and the oil silk rope The free end of 10 passes through the pulley 11 that is fixed on the top of pole 1 and is connected with hoisting weight 2. The connecting piece 3 adopts angle steel, and the angle steel is fastened on the electric pole 1 through the bolt 5 and the cross arm 3 .

Working principle of the utility model:

When the portable hoisting machine is in use, the hoop 6 is fixed on the pole root of the pole 1 by bolts, and then the cross arm 3 is fixed on the pole about 1 meter away from the ground (or from the hoop), and the cross arm 3 It is connected with the hoop 6 by a turnbuckle 7 (tight wire buckle) and a steel wire rope 8, as a cable-stayed support of the device, in order to ensure the pulling force of the cross arm. A manual winch 9 is installed at the end of the cross arm 3 away from the electric pole, the manual winch 9 is fixed on the cross arm 3 by bolts, a pulley 11 is hung on the firm support point of the pole top, and the oil silk rope 10 is wound on the manual winch 9, and The free end of the oil silk rope 10 passes through the pulley 11 to hang the heavy object 2, and adjusts the telescopic distance of the oil silk rope 10 by shaking the handle of the manual winch, and then adjusts the installation height of the heavy object 2. The utility model has a simple structure and is easy to operate. It is convenient, saves time and effort, and improves work efficiency. It is suitable for narrow alleys, fields and other areas where large-scale motorized equipment cannot reach. At the same time, the manual winch has an automatic braking function to prevent the lifting of heavy objects from falling and improve the safety of the equipment.
