(5) УСТРОЙСТВО ДЛЯ УСТАНОВКИ ОПОР . ЛИНИЙ ЭЛЕКТРОПЕРЕДАЧ(5) DEVICE FOR INSTALLING SUPPORT. ELECTRICAL TRANSMISSION LINES

1one

Изобретение относитс к подъемным устройствам специального назначени , в частности к устройствам дл установки опор линий электропередач .The invention relates to lifting devices for special purposes, in particular to devices for installing power line poles.

Известно устройство дл установки опор линий электропередач, содержащее шарнирно установленную на основании падающую стрелу, св занную с поднимаемой опорой, прикрепленной к анкерам посредством канатов .A device for installing power transmission lines is known, which comprises a pivotally mounted on the base a falling boom connected to a raised support attached to the anchors by means of ropes.

Однако это устройство требует использовани дополнительного оборудовани .However, this device requires the use of additional equipment.

Целью изобретени вл етс повышение эффективности путем ликвидации использовани дополнительного оборудовани .The aim of the invention is to increase efficiency by eliminating the use of additional equipment.

Дл этого падающа стрела св зана с опорой двум полиспастами, сбегающие нити которых прикреплены к анкерам, а блоки упом нутых полиспастов снабжены храповыми механизмами .For this, a falling arrow is associated with the support of two chain pulleys, the running threads of which are attached to the anchors, and the blocks of the said chain pulleys are equipped with ratchet mechanisms.

Сущность изобретени по сн етс чертежами,The invention is illustrated by drawings.

На фиг. 1 изображено устройство дл установки опор; на фиг. 2 подн та и раскрепленна стационарными отт жками опора.FIG. 1 shows a device for mounting supports; in fig. 2 raised and fixed by fixed braces support.

Claims

The device contains support 1, fully assembled at the installation site, foundation 2 and anchor 3 stationary fixtures C, 5. 6, 7, two of which C, 5 are connected to anchors 3 With the help of the mounting hinge 8, support 1 is attached to the foundation

2. Spread on the axis of lifting the falling arrow 9 head to the traverse of the support. A falling boom 9 is connected with a cross-piece of support 1 to two chain hoists 10, all blocks of which are provided with ratchet mechanisms. In this case the fixed holders 11 of the polyspasts are fixed on the tip of the falling boom 9 3 movable 12, 13 on the traverse of the support 1. The ropes of the polyspasts 10 are stored so that their free ends escape from the blocks of holders fixed on the traverse of the support. Connect the free ends of the hoist ropes to the anchors. The boom is connected with a tractor 1 with a mounted winch of a tractor. Using, for example, a crane and a mounted tractor winch, the falling boom is moved to its initial lifting position, which is limited by the length of the chain hoists. The device works as follows. Using the cable k, the tangling mechanism rotates the falling boom 9, and the force from the falling boom is transferred to the support 1 through the polyspasts 10. The ropes of the polyspasts are tightened, and the ropes 15 attached to the anchors of the support turn around the mounting joint. In the tensioned position, the ropes 15 perform the role of lateral braces holding the support in the plane of ascent. The main advantage of the tackles performed in this way is that they remain constantly stretched during the lifting process, despite the fact that their size (i.e. the distance from the anchor to the support beam) decreases. The rope released at the same time is distributed in the chain hoists, which leads to a certain amount of distance between the polyplides 10. Holding the support in a given plane during the whole lift is possible due to the presence of ratchets on the collars providing the change in the lengths of the ropes 14 only in the direction of decreasing the delay. E 3- The vertical position of the support is fixed previously fixed on the crossbar and anchors with stationary drawbars +, 5 3 also by attaching to anchors 3 of the same 6, 7, previously attached to the support cross bar. After the support is released, the mounting devices are dismantled. The use of the device for installation of power transmission line supports allows to significantly reduce the labor costs for mounting the support and to refuse additional equipment for keeping the support in the plane of lifting and its braking. The device improves the smoothness of the support, eliminates possible distortions, jerks, increases the safety of installation work. An apparatus for installing power line poles containing a pivotally mounted on the base a falling boom connected to a raised pedestal attached to the anchors by means of ropes, characterized in that, in order to increase efficiency by eliminating the use of additional equipment, the falling boom is connected to two tackles, which run off the threads of which are attached to the anchors, and the tackle blocks are equipped with ratchet mechanisms.
