Description

A wire pay-off trolley with double doors for transmission line stringing

technical field

The utility model belongs to the field of wire construction equipment for power transmission lines, in particular to a double-door wire pay-off trolley for power transmission line stringing.

Background technique

The high-voltage transmission line pay-off block is a special equipment for overhead line deployment. When in use, the guide rope, traction rope or ground wire and other ropes are pulled and walked on its wheels. At present, the frame body connecting plate of the multi-wheel pay-off block is connected with the block frame body two ends by two block pins, and both ends are all locked and can be plugged and opened. During use, the frame body and the connecting plate form a closed quadrilateral, and the tackle pin at one end of the multi-wheel pay-off tackle needs to be opened to put in or take out the rope.

The "rope splitting" process of the current multi-wheel pay-off block is quite troublesome. The so-called splitting rope is to put the rope in the unfolded state from a certain block on a pole tower into the block, or take the rope out of a block and put it into the block. In another tackle on the same tower. The above-mentioned processes all need to open one end of the pulley connecting plate to put in or take out the rope, all of which are done manually with the help of a lever block, motorized winch, wire puller, small pulley, steel wire rope, wire clamp, etc., and it takes 7-8 people to open and hang the rope. board, and the reset is extremely difficult, the safety hazard is great and the operation time is long, as shown in Figure 1 and Figure 2. Large-section wire pay-off block is larger in volume and heavier in quality, and it will be more dangerous, more laborious and time-consuming to take and place the guide rope from the block with the existing method.

The existing block adopts the all-in-one plastic mode, as shown in Figure 6. The rubber on the outer top is easy to wear and tear, causing the rubber to open, crack, and fall off, gradually losing its function and becoming a waste product.

The diameter of the protective sleeve of the large-section wire connection tube is relatively large (such as 1120mm ² , the diameter of the wire connection tube is 95mm), and the bottom diameter of the pulley groove is also required to be large. The contact area between the wire and the bottom of the pulley is small, and it is easy to roll in the wheel groove and deform under pressure. cause damage.
