Problems solved by technology

However, during the use of the tower with inner suspension and outer guy wires, the control requirements for the outer guy wires in the outer guy wire system are extremely strict, and the complex terrain environment in mountainous areas will directly limit the normal use range of the outer guy wires in the outer guy wire system, making the outer guy wires Insufficient terrain space required for the system to work properly
For example, the complex terrain in mountainous areas can allow the extension distance of the outer stay wire to be limited. When the outer stay wire is installed on the pole, the suspension of the stay pole in the center of the transmission line tower truss cannot be successfully completed at one time by using the outer stay wire, that is It is a difficult problem to install the pole in place at one time by using the outer stay wire in the limited terrain, and the fixed end of the outer stay wire on the ground can only fall in the area relatively close to the tower body of the transmission line, so that the outer stay wire The force on the fixed end on the ground is relatively large, and the construction of the transmission line tower will inevitably use components with a relatively large weight, so that there is a greater construction risk during the construction process, and it is easy to affect the transmission line tower.

Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, an electric lifting pole for erecting a transmission line tower includes a pole 2, the bottom of the pole 2 is fixedly provided with a lifting mechanism 1, and the lifting mechanism 1 is used for installing the pole 2, when lifting the pole 2, it also includes a guide mechanism 5, which is used to guide the pole 2 vertically upward when lifting the pole 2, and the guide mechanism 5 passes through the fastener 4 Fixedly arranged on the tower pole 3, the top of the holding pole 2 is provided with a lifting mechanism 6, and the lifting mechanism is used to lift the branch assembly of the transmission line tower when the transmission line tower is erected;

[0024]Wherein, the middle part of the lifting mechanism 1 is provided with a connecting plate 105, and a row of mounting holes 106 are opened on the connecting plate 105, and the connecting plate is installed on the pole through the mounting holes, and the lifting mechanism 1 ru...

Embodiment 2

[0026] In the case of an electric lifting pole for erecting a power transmission line tower described in the above-mentioned embodiment 1, further as follows image 3 and Figure 4 As shown, the guide mechanism 5 is a rectangular frame, and the middle part of each frame of the rectangular frame is provided with a guide pulley 51, and the holding rod is the middle part of the rectangular frame, and the holding rod is in sliding contact with the guide pulley. However, there is no lateral pressure between the pole and the guide pulley. Usually, during the lifting of the pole, the construction system will be unstable due to lateral shaking. If the lateral shaking is too large, it is very likely There will be construction accidents. After the auxiliary function of the guide pulley, the lifting process of the holding pole is more stable, thereby ensuring construction safety.

[0027] Further, the fastening part 4 is welded with reinforcing ribs 41, the reinforcing ribs can strength...

Abstract

The invention provides an electric hoisting embracing pole for building electric transmission line towers in groups. The electric lifting hoisting pole includes an embracing pole body, the bottom of the embracing pole body is fixedly provided with a lifting mechanism, and the lifting mechanism is used for lifting the embracing pole body when the embracing pole body is installed; and the electric hoisting embracing pole further includes a guiding mechanism, the guiding mechanism is used for guiding the embracing pole body vertically upward when lifting the embracing pole body, the guiding mechanism is fixedly arranged on a tower rod through a fastening part, and the top of the embracing pole body is provided with a hoisting mechanism. According to the electric hoisting embracing pole for building the electric transmission line towers in groups, through cooperation of the lifting mechanism and the hoisting mechanism, the spatial position on the side face of the completed electric transmission line tower can be effectively utilized, the embracing pole body is installed as needed, limiting due to the construction complex terrains or small construction ranges of the electric transmission line towers is avoided, and only tiny working plane is required; and meanwhile under the guidance effect of the guiding mechanism, the embracing pole body can further be in place accurately, obstacles avoidance is easy, and occurrence of safety accidents is reduced, the safety risk that electric transmission line towers are built in the mountains in groups is lowered.

Description

technical field [0001] The invention relates to the technical field of transmission line construction, in particular to an electric lifting pole for erecting transmission line towers. Background technique [0002] The most common tower assembly method in the construction of transmission line towers is the tower assembly method of internal suspension and external stays, which mainly uses the erected transmission line tower body to complete the transmission line tower through the supporting system and the external stay system. set up. [0003] At present, with the continuous construction of power transmission and transformation projects, the construction of transmission line towers is basically carried out in mountainous environments. However, during the use of the tower with inner suspension and outer guy wires, the control requirements for the outer guy wires in the outer guy wire system are extremely strict, and the complex terrain environment in mountainous areas will dir...
