Description

Double pole variable platform jack

technical field

The utility model relates to electric lifting equipment, in particular to a double-rod platform-changing jack.

Background technique

In the installation, disassembly and maintenance work of the existing transformer transformer, heavy tools such as cranes and tripods are often used to reinforce sleepers and round logs or I-beams between the two poles of the transformer as support beams, and then set lifting points under the support beams as support beams. Lifting tools for transformers (double-rod transformers). This type of lifting tool requires multiple people to install the support beam during operation and construction, which is time-consuming and laborious, and the labor efficiency is low. It is also easily restricted by the environmental space during specific construction. Therefore, it is very necessary to design a cheap and light lifting device that is easy to operate, can be used in various space conditions.

Contents of the invention

The utility model solves the problems of inconvenient operation of existing electric power construction lifting equipment, constraints of the space environment, and low labor efficiency due to the need for multi-person cooperative operation, and provides a double-rod platform-changing lifter.

The utility model is realized through the following technical solutions: the double-rod platform-changing jack includes a hanger, the hanger includes a frame body, the long ends of the upper and lower surfaces of the frame body are respectively fixed with fixed rings, The fixing rings on the upper surface are respectively hinged with one end of a tension arm, and the other ends of the two tension arms are respectively connected with two-in-one hoops, and the fixing rings on the lower surface of the frame body are respectively connected with one end of a support arm. Hinged, the other ends of the two support arms are respectively connected with a two-in-one hoop; the center of the lower surface of the frame body is also fixed with a lifting ring, and a movable pulley block is connected to the lifting ring; it also includes a fixed pulley and a A lever hoist, the lifting end of the lever hoist passes through the fixed pulley and the movable pulley in sequence. The two ends of the two tension arms on the upper surface of the frame body are fixed to the two rod heads of the double-rod variable platform with two-in-one hoops for hoisting the frame body. The two supporting arms on the lower surface of the frame body support the frame body, and the two ends are respectively fixed on the double-rod variable table rod body with two-in-one hoops. The hoisting ring at the center of the lower surface of the frame body provides a lifting point for the movable pulley block. The movable pulley block saves the pulling force required for hoisting, and the fixed pulley is hung on the rod body on one side of the double-pole variable platform to change the pulling force direction of the lever block. The lever block can further save the pulling force required for lifting.

The utility model has the following advantages: 1. The structure is simple and light, and 1-2 people can complete the installation and operate the hoisting operation, which saves labor; 2. It is not limited by terrain space and is suitable for various narrow space operations; 3. No need for large-scale Coordinated operation of equipment saves production cost; 4. Large lifting weight can hoist transformers of various specifications and models.

detailed description

The double-rod platform-changing jack includes a hanger, and the hanger includes a frame body 1, and the long ends of the upper and lower surfaces of the frame body 1 are respectively fixed with fixed rings 2, and the fixed rings on the upper surface are respectively It is hinged with one end of a tension arm 3, and the other ends of the two tension arms 3 are respectively connected with two-in-one hoops 4, and the fixing rings on the lower surface of the frame body 1 are respectively hinged with one end of a support arm 5, so The other ends of the two support arms 5 are respectively connected with two-in-one hoops; the center of the lower surface of the frame body 1 is also fixed with a lifting ring 6, and a moving pulley block 7 is connected to the lifting ring 6; The pulley 8 and the lever block 9, the lifting end of the lever block 9 passes through the fixed pulley 8 and the movable pulley block 7 in sequence.

During installation and use, a worker climbs the pole bodies on both sides of the double-pole variable platform jack in turn, installs the two-in-one hoop 4 at the end of the two tension arms 3 on the pole body (higher than the installation height of the transformer), and puts The two-in-one hoop 4 at the ends of the two support arms 5 is also installed on the rod body, and ensures that the height of the lower end of the movable pulley block 7 below the hanger is higher than the installation height of the transformer. Then the fixed pulley 8 is hoisted on the rod body on one side, and the lifting end of the handle block 9 passes through the pulleys of the fixed pulley 8 and the movable pulley block 7 in turn, and then the heavy object is hung with a hook hook, and the handle block can be hoisted. lifting objects.
