Problems solved by technology

[0002] The erection of transmission line towers relies on the pole to stand in the center of the tower as the palm for lifting operations. The standing and lifting of the pole requires a lot of waves (wire rope pull wires) to be mastered in the direction of the four corners and on both sides of the hanging piece. Holding the pole When hoisting, it must bear the weight of the hanging parts, as well as the weight of the waves at the four corners and the weight of the hanging parts. Their weight is more than twice the weight of the hanging parts. Excavating anchor pits for fixed construction operations will consume huge material and human resources, which will undoubtedly increase the construction cost of the enterprise and bring operational risks

Embodiment Construction

[0013] Such as figure 1 As shown, part of the tower body 1 formed during the installation process of the line tower, the tower body 1 needs to be developed upwards with the help of the round tower crane type holding pole designed in this scheme, and the holding pole is composed of multiple short holding poles 2, The length of the short pole 2 is about 4.25 meters, and its cross section is circular. The upper section of the combined pole is provided with a pole 3 on both sides, about 8-12 meters in length. Connected, when not in use, the state is as follows image 3 As shown, when vertically connected with the pole, the other end is pulled up with the stay rope 4, and the other end of the stay rope 4 is connected with the top of the pole to form a triangular support.

[0014] The combined holding pole 2 is provided with a waist hoop 5 at two positions in the middle and lower sections, the middle hole of the waist hoop 5 is matched with the surrounding of the holding pole, and ...

Abstract

The invention discloses a sphere tower crane type derrick. The derrick (2) is formed by connecting multiple sections of short derricks, the two sides of the top of the derrick are provided with branch derricks (3) which are perpendicularly connected with the derrick, and guide rails (7) are formed below the branch derricks (3). Two pairs of wheels (9) supporting pulley vehicles (8) at the two sides move in the guide rails (7) under the control of a block (10), a pull rope connected with a winch is contained in a pulley groove in each pulley vehicle for lifting weights, and the derrick is connected with a wire tower under construction through a set of pull ropes including waist hoops (5). The bottom of the derrick is provided with a derrick lifting device. The sphere tower crane type derrick is convenient to use and low in cost.

Description

technical field [0001] The invention is applied to the construction of erecting iron towers for power transmission lines. Background technique [0002] The erection of transmission line towers relies on the pole to stand in the center of the tower as the palm for lifting operations. The standing and lifting of the pole requires a lot of waves (wire rope pull wires) to be mastered in the direction of the four corners and on both sides of the hanging piece. Holding the pole When hoisting, it must bear the weight of the hanging parts, as well as the weight of the waves at the four corners and the weight of the hanging parts. Their weight is more than twice the weight of the hanging parts. Excavating anchor pits for fixed construction operations will consume huge material and human resources, which will undoubtedly increase the construction cost of the enterprise and bring about operational risks. Research and invent suitable hoisting equipment for this reason, put into constru...
