Description

Hand jack for poles

technical field

The utility model relates to a lifting device, in particular to a manual pole jack fixed on an electric pole and used by electric power maintenance personnel.

Background technique

The electric power department often encounters work on poles in daily inspection and maintenance work, that is, the installation of heavy and large equipment and objects such as transformers and circuit breakers. Due to the limitations of the surrounding road conditions and other environments, the crane cannot reach the site. Therefore, it is very inconvenient to transport the equipment to a high place. Nowadays, setting pulleys are mostly installed at high places, and ropes are used to bypass the fixed pulleys to assemble a simple lifting device. This method is laborious, and if you are not careful, the equipment will fall. fall, resulting in loss of personnel and property. Sometimes even if there is a crane, part of the line is in the farmland. When the crane enters the construction site, it will damage the farmers' crops and cause losses to the farmers.

Contents of the invention

The purpose of the utility model is to provide a labor-saving, high-efficiency, quick installation, and easy to carry manual jack for poles.

The purpose of this utility model is achieved in the following way: the manual jack for poles includes two beams on which support rods are arranged, the lower ends of the support rods are connected with hoops, and vertical pieces are arranged on the front ends of the two beams. A fixed shaft is arranged between the sheets, and a capstan is sleeved on the fixed shaft. the

Due to the implementation of the above technical solution, the utility model has a simple structure and can be quickly fixed on the electric pole. It uses a winch to reduce the lifting weight, and can quickly and stably lift the equipment to the working surface, which solves the problem that the high-altitude equipment is not easy to lift. , and protect the safety of lifting personnel and equipment.

Description of drawings: the concrete structure of the present utility model is provided by following accompanying drawing and embodiment:

Fig. 1 is a structural schematic diagram of a manual jack for a pole.

Legend: 1. Beam, 2. Limit rod, 3. Limit block, 4. Hoop, 5. Support rod, 6. Hanging piece, 7. Winch.

Specific implementation methods: the utility model is not limited by the following examples, and specific implementation methods can be determined according to the technical solutions of the utility model and actual conditions.

Embodiment: As shown in FIG. 1 , the manual jack for poles includes two beams 1 on which support rods 5 are arranged, and the lower ends of the support rods 5 are connected to hoops 4 . Hanging pieces 6 are arranged at the front ends of the two beams 1, and a fixed shaft is arranged between the two hanging pieces 6, and a capstan 7 is sleeved on the fixed shaft. A limit block 3 whose inner surface is a circular arc is arranged at the rear of the two beams 1 opposite to each other. The front and rear of the two limit blocks 3 are provided with a limit rod 2 connecting the two beams 1. The limit rod 2 is locked by locking Nut positioning. The two beams 1 can be arranged in parallel, or in a figure-eight shape with a wide front and a narrow rear. Corresponding through holes are opened in the middle of the two cross beams 1, and the opening angles of the two cross beams 1 can be adjusted by adjusting the positions of the limit rods 2 at different through holes and the tightening degree of the lock nuts.

During use, the hoop 4 is set on the electric pole, and the electric pole is snapped into the limit block 3 at the same time. After locking the hoop 4, position the limit rod 2 again. Pulley is installed on the pole tower top, and the wire rope of winch 7 rises into pulley, and the equipment that needs to be installed is fixed firmly with wire rope, and the crank handle on the winch 7 can realize the hoisting of equipment.

The above technical features constitute the best embodiment of the utility model, which has strong adaptability and best implementation effect, and non-essential technical features can be increased or decreased according to actual needs to meet the needs of different situations.
