Problems solved by technology

[0003] The present invention aims to solve the cumbersome rope winding of the pulleys at the hanging point and the binding point of the object in the prior art, and the object is easy to spin when it is lifted from the ground, the ropes between the pulleys are easy to be entangled, and it is impossible to temporarily suspend the lifting work of the goods. Insufficient, it provides a body-type block block that does not need to increase rope pulling personnel, reduces labor costs, solves the cumbersome and easy-to-spin and entanglement problems between the original block blocks, and can realize temporary parking of goods

Embodiment Construction

[0021] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0022] Such as figure 1 , 2 , Shown in 3 and 4, a kind of integrated block block, wherein:

[0023] Comprise a single block 1, a two-two block 2 and the cable 3 that connects the two-two block of the single block, and the two blocks of the single block and the two-two blocks are fixedly connected to the inner two ends of a pair of aluminum alloy splints 4, and between the single block and the two two blocks The spacing is 0.5mm, and the aluminum alloy splint is provided with two reinforcement support rods 5, one is positioned at one end close to the single tackle, and the other is positioned at one end close to the second and second tackles, and the two reinforcement support rods are all located between the single tackle and the second and second tackles , the reinforced support rod runs through the ...

Abstract

The invention relates to the technical field of power transmission line construction equipment, and discloses an integrated pulley block. The pulley block comprises a single pulley, multiple pulleys and a mooring rope connected with the single pulley and the multiple pulleys. The single pulley and the multiple pulleys are fixedly connected to the two ends of the inner sides of a pair of clamping plates, a temporary winding hook is fixedly connected to the outer side faces of the clamping plates, inward concave joints and outward convex joints are distributed on the temporary winding hook in acrossed mode, the inward concave joints are arc sections and are concaved inwards on the temporary winding hook, the outward convex joints are arc sections and are convex outwards on the temporary winding hook, a ground hook is fixedly connected to the ends, close to the multiple pulleys, of the clamping plates, and a pulley door for controlling the multiple pulleys to be turned on or off is arranged on the side faces of the clamping plates. The integrated pulley block has the advantages that no worker for pulling the rope needs to be added, the labor cost is lowered, the original pulley blockinterval is greatly shortened, the problems that rope winding between existing pulley blocks is tedious, and rotation and winding are likely to be caused are solved, and temporary cargo docking can be achieved.

Description

technical field [0001] The invention relates to the technical field of transmission line construction equipment, in particular to an integrated pulley block. Background technique [0002] Pulleys will be used in the construction of transmission line poles and towers or the installation of auxiliary devices. However, when lifting heavy objects, there are two main methods: adding pullers on the ground or using pulleys, and pulling ropes on the ground during busy hours. Shortage and increased labor costs; using the block method because the transmission pole tower is high, it is cumbersome to hang the block set at the hanging point and the object binding point, and the object is easy to spin when it is lifted from the ground, and the rope between the block blocks is easy to be entangled. For example: China Patent Authorization Announcement No. CN108862080A, the authorized announcement date is November 23, 2018, and the name of the invention is a parallel block block, which inclu...
