Description

Portable framework hoisting device

Technical Field

The invention relates to the technical field of power transmission and transformation, in particular to a portable framework hoisting device.

Background

The number of devices to be replaced is large on 35kV and 10kV frameworks, and only a crane and a pull rod are arranged on the aspect of replacing hoisting tools of the framework devices.

The Crane is a common name of a Crane, and the Crane (Crane) is one of hoisting machines and is a machine which does cyclic and intermittent motion. One duty cycle includes: the fetching device lifts the object from the fetching place, then moves horizontally to the appointed place to lower the object, and then carries out reverse movement to return the fetching device to the original position for carrying out the next circulation. Such as fixed rotary cranes, tower cranes, truck cranes, tires, crawler cranes, etc. In the use process of the crane, the requirement on the site is strict, and the power failure range is extremely easy to expand or even the crane cannot be used. In some 35kV substations, equipment replacement on the framework is limited due to the position in the substation, so that a crane cannot be used, and a pull rod is used.

The pulling rod is divided into a single-foot pulling rod, a herringbone pulling rod and a cantilever pulling rod according to the structural form.

The single-foot shifting lever is divided into: wood single-foot stem, steel tube single-foot stem and lattice single-foot stem. The single-foot pull rod consists of a pull rod, a hoisting pulley block, a winch, a cable rope, an anchorage and the like. The number of the guy cables is generally 6-12, and at least not less than 4. The lifting rod keeps an inclination angle of not more than 10 degrees when lifting. The single-foot pull rod is moved by a sled at the bottom of the single-foot pull rod.

The hoisting capacity of the wooden single-foot pull rod is within 100kN, and the hoisting height is generally 8-15 m; the lifting capacity of the steel pipe single-foot pull rod can reach 300kN, and the lifting height is within 20 m; the lifting capacity of the lattice type single-foot lifting rod can reach 1000kN, and the lifting height can reach 70 m.

The herringbone pull rod is generally formed by binding two round timbers or two steel pipes by using a steel wire rope or hinging iron parts. Its advantages are high lateral stability, less guy cables and small range of movement after hoisting. The bottom of the herringbone pull rod is provided with a pull rod or a pull rope to balance horizontal thrust, and the included angle between the two rods is about 30 degrees generally. When the herringbone dead man is lifted, the dead man inclines forwards, and two guy cables are arranged behind the herringbone dead man. In order to ensure the stability of the bottom of the shifting rod during hoisting, a guide pulley is arranged at the bottom of one shifting rod, a hoisting cable is connected to a winch through the guide pulley, and then the hoisting cable is connected to an anchor through another steel wire rope.

The round log herringbone pulling rod has the lifting capacity of 40-140 kN, the length of the pulling rod is 6-13 m, and the diameter of the small end of the round log is 200-340 mm; the lifting capacity of the steel pipe herringbone drawing rod is 100kN, the length of the drawing rod is 20m, the outer diameter of the steel pipe is 273mm, and the wall thickness is 10 mm; the lifting capacity is 200kN, the length of the pull rod is 16.7m, the outer diameter of the steel pipe is 325mm, and the wall thickness is 10 mm.

The cantilever pull rod is formed by installing a crane arm in the middle of the single-foot pull rod or at the height of 2/3. It features high lifting height and radius, and large swinging angle of boom. However, the crane has a small lifting capacity and is mainly used for lifting light members. The boom can also be arranged on the derrick to form a derrick pull rod.

In the transportation process of the pulling rod, the traffic transportation is inconvenient and traffic violation is easily caused due to the overlong pulling rod. 8-10 people are needed in the use process of the pulling rod, the utilization rate of personnel is low, the pulling rod is easy to incline due to the influence of stress, and personal injury can be caused.
