specific Embodiment approach

[0009] Specific implementation manners: the present invention is not limited by the following examples, and specific implementation manners can be determined according to the technical solutions of the present invention and actual conditions.

Embodiment

[0010] Example: such as figure 1 As shown, 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 ...

Abstract

The invention relates to a hand-jack for a rod. The hand-jack for the rod comprises two beams. A supporting rod is arranged on the two beams, the lower end of the supporting rod is connected with a hoop, perpendicular sheets are arranged at the front ends of the two beams, a fixing shaft is arranged between the two perpendicular sheets, and the fixing shaft is sleeved with a winch. According to the technical scheme, the hand-jack for the rod is simple in structure and can be rapidly fixed to an electric pole, the jack-up weight is reduced through the winch, a device can be rapidly and stably hoisted to an operation face, the problem that an altitude plant is not prone to being hoisted is solved, and the safety of a hoisting person and the hoisted device is protected.

Description

technical field [0001] The invention relates to a lifting device, in particular to a manual jack for a pole which is fixed on an electric pole and used by electric power maintenance personnel. Background technique [0002] 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...
